ADJUSTABLE BASE United States Patent Office 3,546,918 Patented Dec. 15, 1970 3,546,918 ADJUSTABLE BASE Donald J. Trainer, P.O. Box 367, 172nd St., Grand Haven, Mich. 49417 Filed Sept. 3, 1968, Ser. No. 757,065 Int. Cl. F16m 11/12 US. Cl. 72446 18 Claims ABSTRACT OF THE DISCLOSURE front to back direction and means are provided to lock the saddle in various positions of adjustment relative to the saddle support. A die holding plate is rotatably secured to the top of the saddle and is adjustable relative thereto. Means are also provided to lock the plate in various positions of adjustment relative to the saddle. Additional support for the saddle support means are provided at a front portion thereof and at a central portion thereof.

This invention relates to an adjustable base for cut-off dies and the like. In one of its aspects, the invention relates to a base containing a base member, a saddle support means adjustably tiltable laterally relative to the base, a saddle adjustably tiltable in a front to back direction relative to the saddle support means and a die holding plate adjustably pivotable about a fixed axis relative to the saddle.

Tishken 3,111,054 discloses an adjustable cut-off machine for severing precurved moving stock, which machine is multiply adjustable to accommodate different curved sections. The machine has a die housing which is tiltable in a front to back direction relative to a bracket, a carriage supporting the bracket for rotation about a generally vertical axis, a carriage support positioned beneath the carriage and secured thereto for tilting in a lateral direction relative to a base. An elevator base is provided for raising the carriage support relative to the base and is shiftable laterally relative to the base. The whole machine, being large and rather bulky, has a moving die incorporated into the machine.

I have now discovered a portable base which can be used in connection with cut-off dies and for other machines, which base is adjustable in ten different ways. The machine employs a die holding plate which is supported by and rotatable relative to a saddle. A saddle support is tiltable in a lateral direction relative to the base and supports the saddle so that it is tiltable in a front to back direction. This construction reduces the size of the base required and permits the base to be used for many different purposes.

By various aspects of this invention, one or more of the following, or other, objects can be obtained.

It is an object of this invention to provide a small compact base which is tiltable in front to back and lateral directions for use in supporting die-cutting machines and other similar apparatus.

It is a further object of this invention to provide a base which is tiltable laterally, front to back, and rotatable about a generally vertical axis.

It is yet another object of this invention to provide a ten way adjustable base wherein a supporting platform for a machine is raisable, shiftable laterally, tiltable laterally, tiltable in a front to back direction, and rotatable about a generally vertical axis.

Other aspects, objects, and the several advantages of this invention are apparent to one skilled in art from a study of this disclosure, the drawings, and the appended claims.

According to the invention there is provided an adjustable base for supporting machinery useful in performing die operations on longitudinally moving, precurved stock. The base comprises a base member having a back, front and sides. A saddle support means is carried by the base and is adjustably secured thereto such that the saddle support means is tiltable about a first axis laterally of the base. Means are provided for releasably maintaining the saddle support means fixed relative to the base.

A saddle surmounts the saddle support means and is adjustably secured thereto so as to be tiltable about a second axis generally transverse to the first axis and generally to permit tilting in a front to back direction. Means are provided to releasably secure the saddle support means to the saddle in a plurality of relative positions. A die holding plate surmounts the saddle and is adjustably rotatable relative thereto about a third axis, generally transverse to the second axis and generally transverse to the first axis. Means are provided for releasably securing the die holding plate to the saddle in a plurality of relative positions. Preferably, the first and third axes intersect at a common point, at which point a die or other similar machines can be positioned for use.

Preferably, the base contains a riser plate supported by the base member so as to be raised and lowered relative to the base member and contains means for releasably securing the riser plate to the base member in a plurality of relative vertical positions. Further, a slider plate is preferably supported by the riser plate for movement laterally of the riser plate. In this embodiment, the saddle support means is secured to the slider plate. Means are preferably provided for releasably securing the slider plate in a plurality of fixed positions relative to the riser plate.

The invention will now be described with reference to the accompanying drawings in which:

FIG. 1 is a perspective view of the base which embodies the invention, the base having positioned thereupon a cut-off die;

FIG. 2 is a side view of the base shown in FIG. 1;

FIG. 3 is a plan view of the base shown in FIG. 2;

FIG. 4 is a partial side sectional view taken along lines IVIV of FIG.'3;

FIG. 5 is an end view of the base shown in FIGS. 1-4;

FIG. 6 is a partial sectional view taken along lines VI-VI of FIG. 2; and

FIG. 7 is a partial sectional view taken along lines VII- VII of FIG. 4.

Referring now to the drawings, an adjustable base 16 supports cut-off die 14 at the end of forming rolls 12. Precurved longitudinally moving stock passes through the forming rolls 12 and into the dies 14 for out off operations. As the forming rolls 12 and the dies 14 are conventional in the art of roll forming, they will not be further described.

The adjustable base 16 has a base member 18 which supports a riser plate 20. A sliding support member 22 is fixed for relative lateral movement on the riser plate 20. A saddle support 24 is secured to the sliding support 22 for tilting movement in a lateral direction relative to the sliding support. A saddle 26 surmounts the saddle support and is secured thereto for tilting motion in a front to back direction relative to the saddle support. A die holding plate 28 is positioned on top of the saddle and is rotatable about a generally vertical axis.

BASE MEMBER The base member 18 comprises a base plate 30 having a rigid upstanding track plate 32 as a back portion thereof. The track plate 32 has forwardly offset upright rails with substantially parallel vertical sides.

RISER PLATE The riser plate comprises a flat plate 36 having on each side thereof clamping flanges 38. The flanges are adjustably secured around the upright rail through bolts 40. Blocks 42 threadably engage rods 44 which support the riser plate 20. Sockets 46in base plate are provided to retain the bottom of the threaded rods 44.

In operation, when bolts are loosened, threaded rods 44 can be turned to raise and lower the riser plate 20 relative to the upper upright rails 34 and the base member 38. When a desired vertical position has been selected, the bolts 40 are tightened against the upright rails 34 so as'to fix the riser plate 20 relative to track plate 32 of adjustable base 16. In this manner, the back end of the machine supporting portion of the adjustable base is raised. The manner of raising the front portion of the machine supporting portion of the base will be described hereinafter.

SLIDING SUPPORT PLATE The sliding support plate 22 comprises a sliding plate 48 having a rearwardly and downwardly depending hook flange 50. Slots 49 are provided in the bottom of the plate (FIG. 6) for engaging bolts 51 which are secured to plate 36. As seen in FIG. 4, the hook flange is positioned between the track plate 32 and the plate 36. A block 52 extends forwardly of the bottom portion of the sliding plate 48 and threadably engages a threaded rod 54 which is journalled at either end in blocks 56 (FIG. 6).

In operation, when it is desirable to move the sliding plate 48 relative to plate 36, the bolts 51 are loosened and the threaded rod 54 is rotated, thereby causing plate 48 to slide along the top portion of plate 36. When the desired position has been reached, the bolts 51 are tightened to secure the sliding plate 48 tightly in the position of adjustment relative to plate 36.

SADDLE SUPPORT MEANS The saddle support means 24 comprises a back plate 58, a pair of parallel side plates and 6-2 fixed to the back plate 58 and extending forwardly thereof, and a front plate 64 fixed to the forward edges of the side plates 60 and 62. The front plate 64 has a curved, upwardly facing arcuate slot 66.

A front supporting member 68 extends upwardly from base member 12 and is fixed thereto through bolt 74 which engages the front supporting member 68. The front supporting member 68 is fixed to flange 72 of the base member 18. A horizontal slot is provided at the bottom of the front supporting member 68 to permit lateral adjustment of the front supporting member 68 as the sliding support 22 is adjusted laterally of the riser plate 20. A bolt 78 extends through front plate 64 at slots 66 and engages a vertical slot 76 of front supporting member 68. The vertical slot permits the saddle support 24 to be raised and lowered as the riser plate 20 is raised and lowered relative to base member 18.

The operation of the lateral movement of the saddle support means relative to the base member is as follows: bolt 74 is loosened prior to the lateral adjustment of the sliding support 22 relative to the riser plate 20. As the threaded rod 54 is turned, the front supporting member 68 is moved a corresponding amount. When the lateral position has been reached, and the front end of the saddle support means has been properly positioned, bolt 74 is 4 tightened to secure the base in the proper lateral position.

Similarly, prior to raising the riser plate, the bolt 78 is loosened to permit the front end of the saddle support means to be raised or lowered as the riser plate 20 is raised or lowered. The front end of the saddle support means is raised or lowered a corresponding amount as the threaded rods 44 are turned to raise or lower the riser plate 20. After the proper vertical position has been obtained, the bolt 78 is then tightened to secure the saddle support means 24 fixed relative to the front supporting member 68.

The back portion of the saddle support means 24 rests on the top surface of the sliding plate 48. An upwardly facing arcuate surface 68 is formed in the top edge of plate 48. A shoe 96 having a lower arcuate edge of the same general configuration as the arcuate surface '98 is fixed to the back of back plate 58. Thus, the saddle support means rests at the back portion on the sliding support 22 through the shoe 96 on the arcuate surface 98.

Arcuate slots 80 are formed in the back plate 58. Bolts 82 are fixed to sliding plate 48 and extend through the arcuate slots 80 to secure the back plate 58 against the sliding plate 48. The bolts 82 are adjustable.

The saddle support means 24 is braced at a central portion thereof by a post 84 having an upper member 85 and a rounded head 86. The upper member is adjustable upwardly and downwardly so as to permit raising and lowering of the support with the up and down movement of the saddle support means. Different size adjustable posts can be used to permit a wide variety of vertically adjustable positions for the cut-off die relative to the base member. A support bar extends between side plates 60 and 62 and contains a socket 92 for receiving the rounded head 86 of the post 84. At the bottom portion thereof, the post is laterally slidable within angle bars 88 on base plate 30.

Oppositely facing support bars extend forwardly from sliding plate 48. The support bars have forwardly extending portions 102, outwardly extending portions 104, and forwardly extending portions 106. A threaded rod 108 is journalled at the ends thereof in the forwardly extending portions 106. A bar 110 (FIG. 4) threadably engages the threaded rod 108 and is positioned within slots 112 of depending plates 114. A cross plate 116 is secured to the side plates 60 and 62 and is secured to the depending plates 114.

The side plates 60 and 62 of the saddle support means have valleys 118, a peak 120 and valleys 122. The valleys 118 and 122 permit substantial front to back tilting of the saddle relative to the saddle support means.

The construction is such that the saddle support means is tiltable in a lateral direction, i.e. about a horizontal axis perpendicular to a sliding plate 48, relative to sliding plate 48 and also relative to base member 18. The operation of the lateral tilting of the saddle support means relative to the sliding plate 48 is as follows: bolts 82 and 78 are loosened. Threaded rod 108 is rotated and post 84 is moved laterally as the tilting takes place. During the tilting, the bolts 82 will slide in slots 80 and the bolt 78 will slide in slot 66.

It is obvious that the center of curvature of slot 66 as well as the center of curvature of slots 80 lies on the axis of rotation of the carriage support means. The radius of curvature of the slots and the radius of curvature of the arcuate surface 98 determine the axis of rotation of the saddle support means. It is, therefore, apparent that the base can be made so as to tilt laterally about an axis at any given height. Preferably, the tilting axis will pass through the working area of the equipment supported on the die holding plate 28.

When the desired tilting position has been reached, proper vertical adjustment is made to post 84, and bolts 82 and 78 are then tightened to fix the saddle support means relative to the sliding support 22.

THE SADDLE The saddle 26 comprises a top plate 124 and depending side plates 126. An axle 128 having end bolts 130 extends through the depending side plates 126 and through the side plates 60 and 62 of the saddle support 24 at peak 120.

Arcuate slots 132 and 134 are formed in each depending side plate 126. Bolts 136 extend through the slots 132 and 134 and are fixed to each side plate 60 and 62.

The depending side plates 126 have rounded bottom edges 138 with a center of curvature at axle 128. Arc plates 94 are fixed to the side plates 60 and 62 and have arcuate upper edges which bear against the surface 138 and help to support the saddle 26.

A tab flange extends downwardly and outwardly of the bottom portion of one of the depending side plates 26. A swivel shoulder 142 is rotatably journalled in the tab flange and, in turn, threadably engages a threaded rod 144. A second swivel shoulder 146 is rotatably journalled in plate 148 which is fixed to side plate of the saddle support. The threaded rod 144 is journalled in the swivel shoulder 146.

The operation of the front to back tilting of the saddle relative to the saddle support means is as follows: when it is desirable to tilt the cut-off die supported by the base in a front to back direction, bolts 136 are loosened and threaded rod 144 is rotated so as to move the saddle support about an axis passing through axle 130. When the desired position is reached, the bolts 136 are tightened to secure the saddle 26 relative to the saddle support means 24.

The top plate 124 contains a large circular hole 152 with a machine annular recess 150. Arcuate slots 160 and 162 are provided at either side of the top plate 124 and have a center of curvature at the central portion of the large circular hole 152. A tabular flange 174 extends out from plate 124 and rotatably supports a swivel shoulder 172.

THE DIE HOLDING PLATE The die holding plate 28 has a large circular hole 158 and a machined annular recess 154. An annular ring 156 is positioned within the machined annular recesses and 154 so as to guide the rotation of the die holding plate 28 relative to the top plate 124 of the saddle 26. Bolts 164 are fixed to the die holding plate 128 and extend through the arcuate slots and 162 of the top plate 124.

A L-shaped tubular flange 166 extends down from an outer edge of the die holding plate 28. A swivel shoulder 168 is rotatably supported by the L-shaped flange 166 and threadably engages a threaded rod 72.

The operation of the rotation of the die holding plate relative to the saddle is as follows; when it is desirable to rotate the die holding plate about an axis perpendicular to the top plate 124 of the saddle 26, the bolts 164 are loosened and the threaded rod 170 is rotated. The rotation of the threaded rod about its longitudinal axis forces the die holding plate 128 to rotate about an axis through the center of the large circular hole 152 relative to the top plate 124. When the desired position has been reached, the bolts 164 are then tightened to maintain the die holding plate 128 fixed relative to the top plate 124.

Whereas the invention has been described with reference to the positioning of arcuate slots in a certain plate and fixed bolts in adjacent plate, it is obvious that within the scope of the invention, the position of the fixed bolts and the arcuate slots can be interchanged without departing from the spirit of the invention.

The base described thus provides a novel supporting means which can support a machine which can be positionally adjusted ten ways. The machine can be raised or lowered and it can be moved laterally. The machine can be tilted to the right or left and it can be tilted in a back to front direction. Further, the base provides a rotation of the .machine about a fixed relatively vertical axis. Thus, the

machine positioned on the base can be rotated about three transverse axes. In the preferred embodiment shown in the drawings, the machine can be rotated about three mutually perpendicular axes.

In addition to the cut-off die, the base can support a punch press, a drill, or forming dies. Many other uses of the base will be suggested to those skilled in the art.
