WWI/way I Patented July 20, 1943 UNITED STATES PATENT OFFICE 2,324,803 WORK HOLDER La Verne s. Snyder, Baltimore, Md. Application May 2, 1942, SerialNo. 441,440 1 Claim. (0129-89) The present invention relates to new and useful improvements in work holders, particularly for welding, although it will be understood, of course, that the device may be used for any other purpose for which it may be found adapted and desirable.

The primary object of the invention is to provide, in a manner as hereinafter set forth, a holder .of the aforementioned character comprising a novel construction and arrangement whereby the device may be expeditiously adjusted for firmly securing pieces of work of various shapes and sizes in position for welding.

Other objects of the invention are to provide an adjustable work holder or clamp of the aforementioned character which will be comparative- 1y simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of an adjustable work holder constructed in accordance with the present invention.

Figure 2 is a view in side elevation of an intermediate portion of the adjustable supporting arm.

Figure 3 is a top plan view thereof.

Figure 4 is a View in vertical longitudinal section through a portion of the adjustable supporting arm.

Figure 5 is a View in side elevation of one of the clamps, showing the adjustable jaw in vertical section,

Figure 6 is a view in front elevation of one of the clamps.

Figure '7 is a detail view, showing a modified construction for the supporting arm.

Figure 8 is a cross-sectional view through the modification, taken substantially on the line 88 of Figure '7.

mounted on the other end portion of the frame 5 is a thumb screw I. A substantially V-shaped jaw 8 is rotatably mounted on one end portion of the screw I for adjustment toward and away from the stationary jaw 6.

The jaw B has formed therein a socket 9 for the reception of a ball head ID on one end of the screw I. The head I0 is joined to the screw I by a neck II. A spring pressed detent I2 is provided in the jaw 8 for engagement with the neck I for removably securing said jaw in position on the screw I. An operating handle I3 is) provided on the upper end of the screw I.

Threadedly mounted in sockets which are provided therefor in the frame 5 is a plurality of shanks I4. The shanks I4 are square in crosssection to receive a wrench or other tool. Stop collars I5 are provided on the shanks I4 for engagement with the frame 5. vided on the outer ends of the shanks I4.

A duplicate clamp H is mounted on the clamp 4 through the medium of an adjustable supporting arm I8. The adjustable arm I8 includes alternating links and connectors A and B, respectively. The connectors B comprise shanks I9 having integral balls 20 on their ends. The links A comprise complemental double ended jaws 2| formed to provide sockets for the reception of the balls 20. Bolts 22 clamp the opposed jaws 2I' on the balls 20 for frictionally securing any desired adjustment of the arm I8. The bolts 22 are provided with securing nuts 23. Lock washers 24 are provided on the bolts 22 beneath the nuts 23. As illustrated to advantage in Figure 4 of the drawings, the heads of the bolts 22 are countersunk in the links A.

The links A are provided on both ends of the adjustable arm I8. These end links A are clamped on one of the balls I6 on each of the clamps 4 and I1. One of these links A is also clamped on the other ball I6 of the clamp 4 and on the ball 3 for adjustably mounting said clamp 4 on the post 2. The opposed end portions of the jaws 2I are vertically and horizontally slotted, as at 26, to accommodate the shanks I9 of the connectors B. This permits the links A and the connectors B to be conveniently swung to substantially any desired position for obtaining various adjustments.

It is thought that the manner of using the device will be readily apparent from a consideration of the foregoing. Briefly, one of the pieces of work to be welded is mounted in the clamp 4 and the other piece is mounted in the clamp I'I. These clamps are then adjusted to position the Balls I6 are protwo pieces of work relative to each other for welding, which may be expeditiously accomplished by reason of the adjustability of the arm [8 and the mounting of the clamp 4 on the post 2. If desired, one or more of the nuts 23 may be loosen-ed to facilitate adjusting the clamps 4 and I! relative to each other. These nuts 23 also permit the frictional grip of the jaws 2| on the balls 20 to be regulated as desired. The substantially V- shaped jaws 8 are primarily to accommodate round work. However, other shapes of jaws are to be provided to accommodate other shapes of work. For example, flat jaws would be provided for flat work.

In the slight modification illustrated in Figures 7 and 8 of the drawings, links C are coupled by the connectors B. The links C comprise jaws 21 for the reception therebetween of the balls 20, said jaws 21 being spaced from each other sufficiently to permit the shanks I!) of the connectors 13 to swing around therebetween.

It is believed that the many advantages of an adjustable work holder constructed in accordance with the present invention will be readily understood, and although preferred embodiments are as illustrated and described, it is to be understood that further modifications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A Work holder comprising a clamp including a substantially U-shaped frame, shanks projecting from the frame at right angles to each other, balls on said shanks, means engaged with one of the balls for adjustably mounting the clamp on a support, and another clamp adjustably mounted on the other of said balls, LA VERNE S. SNYDER.
