AND THE LIKE Walter E. Billman, Philadelphia, Pa.
Application May 29, 1944, Serial No. 537,888
The present invention relates to new and useful improvements in bolt or screw clamping devices adapted for holding such articles firmly while being worked upon.
An important object of the present invention is to provide a plurality .of cooperating clamping plates between which screws or bolts of various sizes may be clamped in tight engagement without danger of injuring the threads thereof, the clamping holder being adapted for placing between the jaws of a vise in order that the screws or bolts may be worked upon, such as bumng the screw 2 Claims. (01. 29-284) 2 out should at any time the head of the bolt be sheared off.
The outer surface of the plate 6 is rabbeted or notched, as shown at [2, to reduce the thickness of the plate at the end portions thereof to-accommodate the head In of the bolt so that the heads head, milling slots in the screw head, cutting off the screws to shorter length, polishing, filling,
drilling, or performing other desired work thereon.
A still further object is toprovide a device of this character of simple and practical construction, which is efiicient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same in intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a plan View of the clamping holder shown in assembled position between the jaws of a vise and with parts broken away and shown in section, and
Figs. 2 and 3 are sectional views taken respectively on the lines 2-2 and 33 of Fig. 1.
Referring now to the drawing in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates the clamping holder generally, which includes a pair of side clamping plates 6 and I and a center or intermediate clamping plate 8. As shown, all three of the plates are of truncated triangular formation, the larger bases of the plates 5 and 8 and'the smaller base of the plate I being in aligned relationship at one end and the larger base of the plate I and the smaller bases of the plates 8 and 5 being in aligned relationship at the other end.
At each end of the holder a. bolt 9 is freely inserted through the plates 6 and =8, the end of the if bolt being threaded for threaded engagement in the plate I. The bolt 9 is formed with a head It having a hexagonal recess II to receive a socket wrench adapted for tightening the bolt in the plate. The bolt 9 has a screw driver kerf in the end thereof so that the bolt may be turned of the bolts will not interfere with the clamping of the holder between the jaws l3 and M of a vise.
Both clamping faces of the center plate 8 and the opposed clamping faces of the end plates 6 and l are formed with semi-circular opposing recesses l5 having threads l6 formed thereon adapted to receive the threads of bolts or screws positioned in the openings thus formed so as to clamp the bolts or screws in position without danger of damage to the threads of the latter.
A portion of certain of the openings I5 may be smooth bored, as shown at l l, in Figure 3..
The openings I5 may be formed of various sizes to accommodate bolts or screws of various sizes or diameters and the plates adjacent the respective openings may be suitably marked to indicate the diameter thereof.
By placing the screws or bolts between the clamping plates the same will be firmly held in position while working thereon, and if desired the assembled plates may be secured in position between the vise and the jaws, as indicated.
It is believed the details of construction and manner of operation and advantages of the devices will be readily understood from the foregoing without further detailed explanation.
Having thus described the invention, what I claim is:
1. A clamping holder of the class described comprising a plurality of truncated triangular plates positioned in aligned relationship, the larger bases of the first and second and the smaller base of a third plate being aligned at one end and the larger base of the third and smaller bases of the,first and second plates being aligned at the other end, a plurality of screw-threaded holes of uniformly diminishing diameter along the line of separation of the first and second plates, each hole being formed half in one plate and half in the other, and a plurality of screwthreaded holes of uniformly increasing diameter along the separation line between the second and third plates, each hole being likewise half in one plate and half in the other, and a securing device holding said plates in aligned relationship.
2. In a clamping holder of the class described, comprising a plurality of truncated triangular plates, the larger bases of a first outer and an intermediate plate and the smaller base of a second outer plate being in aligned relationship at one end and the larger base of a second outer and the smaller bases of the intermediate and first outer plates being in aligned relationship. at the other end, a plurality of screw-threaded holes of uniformly diminishing diameter along the separation line between the first outer and the intermediate plates. each hole being; formed half in one plateand half in the other, and a. plural.- ity of holes of uniformly increasing diameter along the separation line between the intermediate and the second outer plates, each hole be,- ing likewise formed half in one plateand half" in the other, notched corners on the ends of one outer plate, aligned holes extendingirom thenotched corners transversely t iqugh all the plates, said holes in the second outer plat-e being screw-threaded for the reception of fastenin bolts.
