[57] ABSTRACT A vertically disposed press having two spaced' apart vertical legs and also having a horizontal work support bed between the legs which is adjustable vertically so as to support a work piece beneath a hydraulic press carried by the frame. The bed is mounted in cantilever fashion by means of rollers at one end which ride up and down on opposite sides of one of the vertical legs. When the bed has been positioned at the proper elevation, it is easily locked in place to both of the legs for securely supporting the work piece in position. The press also includes a hydraulic cylinder connected by a tension member to one end of the bed and by means of which the bed can be easily and quickly adjusted in a vertical position along the vertical legs.
8 Claims, 5 Drawing Figures SHEET 2 OF 2 PATENIEB JAN 7 I975 1 H-FRAME HYDRAULIC PRESS BACKGROUND OF THE INVENTION Prior art H-frame hydraulic presses usually employed pulleys, cables and winches and the like and which were connected to both ends of the bed for positioning the latter in the frame. These devices were difficult to operate and adjust and employed numerous parts which were not only expensive to manufacture, but were difficult to maintain. Furthermore, these prior art presses could not be quickly adjustable nor did they provide adequate spacing in the bed for conveniently holding the work piece. or fixtures.
SUMMARY OF THE INVENTION The present invention provides an H-frame hydraulic press having two spaced apart vertical supportmembers which are rigidly secured together at their upper ends and which can support a hydraulic press means for performing work on a work piece that is located between thevertical members. The press also includes a generally horizontal work support bed which extends between the vertical members, the bed including a cantilever beam which is supported by rollers at one of its ends on one of the vertical supports. The roller support member securely embraces opposite sides of the one vertical member and its rollers engage opposite sides of BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front elevational view of the hydraulic press embodying the present invention;
FIG. 2 is a side elevational view of the press shown in FIG. 1;
FIG. 3 is a top view of the press shown in FIG. 1;
FIG. 4 is an enlarged, fragmentary view of one end of the bed shown in FIG. 1, certain parts being shown in section. or broken away for the sake of clarity; and
FIG. 5 is an enlarged, perspective exploded view of the bed and a certain portion of the frame shown in FIG. 1.
DESCRIPTION OF A PREFERRED EMBODIMENT The main frame of the press is comprised of two spaced apart vertical support members land 2, each of which in turn is comprised of a pair of parallel plates 3 and 4 having a series of aligned holes 5 therein and along their length. Cross braces 6 are welded between the plates 3 and 4 so as to form the rigid vertical support. The upper ends of the vertical supports are rigidly secured together by a cross brace 7 which is comprised of two channel members 8 and 9 arranged on opposite sides of the legs 3 and 4 and welded thereto so as to form a rigid main frame structure. Mounted centrally on the cross brace 7 is a portion of a hydraulic press means 10 by means of which hydraulic force can be imparted to a work piece (not shown) carried between the vertical legs and on the bed to be described.
To the lower end of the vertical legs are rigidly attached twofeet members 13, 14 so as to provide a stable base for the press. I
A work piece bed B extends between and across the vertical legs and can .be adjusted to any vertical posi tion so as to support a work piece on which work is to be performed by the hydraulic press means 10. The generally horizontal work support bed includes a cantilever beam 20 that is fabricated from two steel channels 22 and 24 that are rigidly secured together by the cross braces 25 welded therebetween. The channels 22 and 24 are located on opposite sides of the vertical legs and can slide up and down relative thereto. It will be noted that the space between the channels 22 and 24 is considerable so as to easily accommodate a work piece or other jigs or fixtures. The bed also includes a generally upwardly extending roller support member RS which is comprised of two plates 30 and 31 that are welded to their channels 22 and 24 of the beam. As shown in FIG. 5, a brace 33 is also welded between the plates 30 and 31 and has a hook 34 welded centrally thereon. It will be noted that the plates 30 and 31 are located on opposite sides of one of the vertical legs. Two pairs of rollers 36 and 38 are rotatably supported between the plates 30 and 31, one pair of rollers bearing against one side of one of the legs and the other rollers 38 bearing against the opposite side of the other of said legs. More specifically, the rollers 38 are mounted on shaft 37, the ends of which shaft are located in elongated slots 37 in the plates30 and 31. This permits the rollers to be adjusted in the slot and thus permit accurate leveling of the beam 20. Set screws 39 are threadably engaged in the plates 30 and 31 and abut against the shaft 35 to thus provide limit stops for the shaft in its adjusted position.
Thus, the rollers bear against the two legsand support the beam in cantilever fashion.
The beam can be rigidly secured at their legs by means of the removable pins 40 and 41 which extend through the holes 43 and 44 in the beam and the holes are aligned with holes 5 of the legs.
The hydraulically operated cylinder C is fixed by brackets 48 adjacent the top of the frame and a tension member 50 in the form of a flexible chain is connected between the rod 51 of the cylinder C and the hook 34 of the roller support member RS.
The bed can thus be readily adjusted at one of its ends by means of the cylinder, the rollers acting to absorb the weight of the beam and thus the bed can be vertically positioned without any binding between the parts. When the beam is located in the proper vertical position, the pins 40 and 41 are inserted through the aligned holes in the beam and legs thus locking the bed tween said vertical members; said bed including a cantilever beam and a roller support member rigidly fixed' to one end of said beam, said roller support member engaging one of said vertical support members, rollers carried by said roller support member and for engaging said one of said vertical members and thereby supporting said beam in cantilever fashion, and means for rigidly securing said beam to each of said vertical members, a fluid operated cylinder secured adjacent the top of said press, and a tension member connected between said hydraulic cylinder and said bed whereby the latter can be vertically positioned along said vertical members by said hydraulic cylinder and rigidly fixed with said vertical members in any one of a number of positrons.
2. The press set forth in claim 1 further characterized in that said beam includes two steel chambers rigidly secured together in spaced apart parallel relationship, and said roller support member includes two spaced apart, upwardly extending plates, and said rollers are rotatably mounted to and between said plates.
3. The press as described in claim 1 further characterized in that said fluid operated cylinder is secured to said one of said vertical members, and said tension member is a flexible chain; said roller support member having a hook fixed thereon, and said chain is adjustably connected to said hook.
4. The press as described in claim 2 further characterized in that said fluid operated cylinder is secured to said one of said vertical members, and said tension member is a flexible chain; said roller support member having a hook fixed thereon, and said chain is adjustably connected to said hook.

and a tension member connected between said hydrauv terized in that said fluid operated cylinder is secured to said one of said vertical members, and said tension member is a flexible chain; said roller support'member having a hook fixed thereon, and said chain is adjustably connected to said hook.
