GRADUATED-SPACING TABLE.

Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed April 9, 1909. Serial No. 488,959.

To all whom it may concern:

Be it known that I, THOMAS V. BOYLE, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Graduated-Spacing Tables, of which the following is a specification.

My invention relates to graduated spacing tables for use in punching angle irons, rails and other work, to locate the holes without first marking the same upon the work, and my object is to provide certain novel features of construction and arrangement which will be hereinafter specifically designated and referred to.

In the accompanying drawings which illustrate my invention, and form a part of this specification, Figure 1 is a side elevation of a device constructed in accordance with my invention and broken away. Fig. 2 is a cross section therethrough on line 1919 of Fig. 1. Fig. 3 is a detail plan view of a portion of the graduated table. Fig. 4: is a detail sectional view through the lower bracket and table. Figs. 5 and 6 are detail perspective views of the stop blocks, and, Fig. 7 is a detail perspective view of one of the adjustable shaft bearings.

Referring specifically to the drawings, a carriage 1 travels longitudinally upon the upper edges of vertical spaced side members 16, constituting the stationary frame, one of which side members 16 has a horizontal outstanding table 8, and the carriage 1 having an outstanding horizontal bracket 2, above said table 8 and parallel therewith. The carriage 1 further has a clamping device 1 to clamp the work and feed the same beneath the punch 15 upon the movement of said table, which is effected by means of a handle 7 at the extremity of its bracket 2.

The carriage bracket 2 has a plurality of vertical openings 2, enlarging downwardly, and upstanding ears 5 adjacent each of said openings, to which ears 5 are intermediately pivoted controlling levers 3, having depending controlling bars 6 loosely secured at their upper ends thereto at one side of the pivot, which bars have flaring lower ends 6 Levers 3 also have counter balancing weights & upon their ends at the opposite sides of their pivots, to hold the said ends downwardly against an upstanding ledge 2 of bracket 2, when said levers are moved to the horizontal position shown in full lines in Fig. 4, it being understood that a selected lever is moved downwardly to lower its bar 6.

The table 8 has a plurality of longitudinal parallel channels 17, in its upper face, corresponding to the number of levers 3, each of which channels 17 has a plurality of circular apertures 17 equally spaced apart as shown by reference to scale 17 These openings are adapted for the reception of the stop blocks 9, shown in various shapes in Fig. 3, and comprising, as shown in Figs. and 6 a cylindrical body 9 and a head 9*, which may extend from one side of the center of said body, the body 9 being inserted in openings 17*, with heads 17, resting in, and projecting above the channels 17 into the path of its corresponding bar 6.

In punching long work, a shaft 14: extending transversely between the sides 16 of the stationary frame, and provided with rollers 10, may be utilized to feed such work, the ends of said shaft resting in journal blocks 13, having diagonal side flanges 13 for engagement in selected ones of the vertical se ries of diagonal slots 12 in the opposing faces of spaced parallel vertical beams 11 secured upon the inner surfaces of the said frame sides 16, and thus rendering said shaft vertically adjustable to accommodate different sizes of work.

Thus in use, a rail or other work having been clamped in the device 1, and stops 9 having been placed within various openings 17, in channels 17, according to the desired spacing of the openings to be punched in the work, and the corresponding bar 6 having been depressed by downward movement of its lever 3, the carriage 1 is moved until bar (3 engages the first stop 9, when the first punching operation takes place. Should the spacing for a certain hole, be say, two and three-eighths inches, a stop block 9 having an offset head 9 is placed in the three-inch hole with its head extending five-eighths of an inch in advance thereof, (going by the graduation 17). By the employment of a plurality of channels and levers, and the structure thereof and of the steps, I am thus able to provide for a number of jobs, which may be continuously run through, or one job may be set up or spaced while another is be ing punched. Further, levers 3 are as shown in Fig. 1, of different lengths, in order that the inner ones may be readily grasped, and inasmuch as bars 6 have slight sidewise movement in their tapering openings 2 thecarriage is stopped with the opening directly above the stop block.

From the foregoing, it will be seen that the carriage may be moved in either direction to feed the work beneath the punch.

Having fully described my invention, I claim:

1. In a spacing machine of the character described, the combination with a movable carriage having means to clamp the work, of a spacing table provided with a plurality of longitudinal parallel slots, and with openings therethrough in said slots, a plurality of stop members, corresponding in number to said slots, carried by said carriage, a plurality of stop blocks for insertion within se lected openings in said slots, and means for independently moving said carriage stop members into, and out of, the path of said stop blocks.

2. In a spacing machine of the character described, the combination of a spacing table having a plurality of longitudinal parallel slots, and openings therethrough in said slots, a plurality of stop-blocks, comprising body portions for engagement in selected ones of said openings, and varyingly shaped heads extending upwardly out of said slots, and a movable carriage having elements to contact with said heads of said stop blocks.

8. In a spacing machine of the character described, the combination of a spacing table having a plurality of longitudinal parallel slots, and equi-distantly spaced openings therethrough within said slots, a plurality of stop blocks comprising body portions for engagement in selected ones of said openings, and heads carried by said body portions and projecting upwardly out of said slots, certain of said blocks having their heads ofiset from their body portions, and a movable carriage having elements to contact with said heads of said stop blocks.

4. In a spacing machine of the character described, the combination of a spacing table having a plurality of longitudinal parallel slots, and openings therethrough, within said slots, stop blocks for insertion within selected ones of said openings to project out of said slots, a movable carriage having a portion thereof projecting above said table and provided with vertical openings therethrough alined with said table slots, contact bars depending through said slots, levers pivoted upon said carriage portion to which said contact bars are connected to project the same into, and out of, the path of said stop blocks, and counter-balancing weights carried by said levers.

5. In a spacing machine of the character described, the combination of a spacing table having a plurality of longitudinal parallel slots, and openings therethrough within said slots, stop blocks for insertion within selected ones of said openings to project out of said slots, a movable carriage having an outstanding bracket projecting above said table and provided with a series of vertical downwardly enlarging openings alined with said table slots, levers pivotally mounted upon said bracket independent of one another and provided with counter-balancing weights, and bars pivotally connected to said levers and depending therefrom through said bracket openings and movable into, and out of, the path of said stop blocks.

6. In a spacing machine of the character described, the combination of a spacing table, a movable carriage, relatively engageable stop members carried by said table and said carriage, means carried by said carriage to clamp the work, a frame upon which said carriage moves embodying vertical side members, a roller shaft for the work, extending transversely between said side members, and journals for the ends of said shaft, vertically adjustably mounted upon said side members.

In testimony whereof I aflix my signature, in presence of two witnesses.

THOMAS V. BOYLE.
