SPECIFICATION forming part of Letters Patent No. 767,876, dated Aug 16, 1904-. Application filed May 9, 1903. Serial No 156,434. (No model.)
To all whom it may concern:
Be it known that I, OTTO H. EIOHBLATT, a citizen of the United States, residing at Skidmore, in the county of Bee and State of Texas, have invented new and useful Improvements in lVork-Holders, of which the following is a specification.
My invention relates to new and useful improvements in work-holders, by means of which an object to be drilled may be securely fastened in position upon the table of a drillpress.
An object of the invention is to provide adjustable jaws for securely clamping the work in position. i
A further object is to employ an adjustable bed for the jaws which may be moved fromor toward the drill, so as to preventspringing of the work during the operation of drilling. With the above and other objects in view the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, in which Figure 1 is a plan view of a Work-holder constructed in accordance with my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a section on line 3 3, Fig. 2. Fig. 4' is a plan view of a modified form of holder, showing the use of holding-blocks for cylindrical objects; and Fig. 5 is a side elevation showing the use of holding-blocks for retaining cylindrical objects in horizontal position.
Referring to the figures by numerals of reference, 1 1 are parallel beams having longitudinally-extending slots 2 therein, the sides of which are countersunk at their lower edges, as shown at 3. These beams are connected at opposite ends by adjusting-screws 1, which are swiveled in one of the beams 1 and engage the other beam, so that when the screw is rotated by means of a bar 5 engaging the free end thereof said beams may be adjusted from or toward each other. Blocks 6 are slidably mounted within the countersunk portions 3 of the sides of the slots 2, and each block is engaged bya bolt 7, which extends upward through one of the slots 2 and through a slot 8, extending longitudinally of a flange 9, formed at the lower edge of a jaw 10. This flange is adapted to be clamped upon the beams 1 by turning the heads 11 of the bolts 7, engaging the same, so as to bind it upon the beams. Two jaws 10 and flanges 11 are arranged upon the beams 1, and these jaws areoppositely disposed, so that any form of work 12 may be clamped therebetween. An auxiliary jaw 13 is arranged upon the beams 1 adjacent to one of the jaws 10 and is provided with a base-flange 14, having a longitudinally-extending slot 15 therein, through which extend clamping-bolts 16, similar to the bolts 7, hereinbefore referred to, and pro vided with similar blocks 6 within the countersunk portions 3 of the sides of slots 2. Within the jaw 13 are mounted set-screws 17, the ends of which bear upon the adjacent jaw 10.
When it is desired to drill a piece of work, the same is placed 'between the jaws 10, and by turning the adjusting-screws 4 the beams 1 may be brought toward each other a desired distance, a space being preferably left therebetween of suflicient size to permit the passage therethrough of the drill to be employed. The bolts 16 of the auxiliary jaw 13 and the bolts 7 of the jaw 10 adjacent thereto are then loosened and said jaws adjusted toward the work. Jaw 13 is then clamped in position by means of the bolt 16, and set-screws 17 are rotated, so as to clamp the adjacent jaw 10 upon the work 12. The bolts 7 of said jaw 10 can 7 then be tightened, so as to securely lock the same in adjusted position. Where it is desired to hold a cylindrical piece of work between the jaws 10, work-holding blocks 18 are preferably employed, and each of these blocks has a V-shaped recess 19 in its working face, and these recesses are oppositely disposed, so as to receive the opposite sides of the work. I have illustrated these work-holding blocks in Fig. 1, and in Fig. 5 I have shown the blocks 19 having longitudinally-extending V- shaped recesses 2O in the working faces thereof. By employing these blocks cylindrical work may be held in a horizontal position. In the various figures I have indicated the drill to be used upon the work by the numeral 21.
it will be understood that my improved work-holding devices are to be secured to the table of a drill-press in any suitable way, as by means of a clamp or clamps, (not shown,) which may be tightened upon parts of the beams l subsequent to adjustments of said beams through the medium of screws 4.
In the foregoing description l have shown the preferred form of my invention; but 1 do not limit myself thereto, as 1 am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.
Having thus described the invention, what is claimed as new is l. The combination with longitudinallyslotted beams, and means for adjusting said beams from or toward each other; of jaws arranged transversely upon the beams, longitudinally-slotted flanges to the jaws, and clamping means within the slots of the flanges and beams, whereby the jaws may be secured in adjusted positions.
2. The combination of parallel separated beams, each having a longitudinal slot therein, screws connecting the beams for adjusting the same toward and away from each other, transverse jaws adjustably mounted upon the beams, each having a base-flange formed with a longitudinal slot, screws within the slots of said beams and flanges, and devices for tightening said screws to secure said jaws in different positions.
1n testimony whereof I afiix my signature in presence of two witnesses.
OTTO H. EICHBLATT.
