To all whom it may concern:
Be it known that 1, JOHN CUTHBERT, a
citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wire-Clamping Devices, of which the following is a specification.
My invention relates to wire binding clamps with which to attach electrically 0on ducting wires to electric fittings, instruments, and other like translation devices.
One of the objects of my invention is to provide a wire clamping connector whereby around the shank of a binding screw, or stud, and subsequently clamped in place by the mere act of turning the screw, nut or other threaded clamping agent.
Another object of my invention is to pr vide simplified means whereby to coil the wire'around a stud or shank of a screw and to hold it in intimate contact therewith during the coiling operation, and to clamp the wire between the coiling means and a rela-' tively stationary part, by a single operation, thus greatly increasing the time efliciency of the device.
Other and further objects of my invention will become readily apparent, to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherei1'1:
Figure 1 is a block of insulating material showing, in plan view, several forms which my invention may take. Fig. 2 isa sectional view, taken on line 22 of Fig. 1. Fig. 3 is a sectional view showing the wire inserted prior to being coiled and clamped. Fig. 4 is a perspective view of one form of clamping screw, inverted. Fig. 5 is a side elevation of another form, or modification that my invention may take. Fig. 6 is a plan view of the same. Fig. 7 is an end view of a cap screw havin a wire coiling projection from the under si e of its head. Fig. 8 is an elevation of said screw. Fig. 9 shows a nut on a screw threaded stud with a wire coiling projection shown in dotted lines.
In all the views the same reference charactors are employed to indicate similar parts.
In connecting electrically conducting wires to terminals of electro-responsive devices, it
has been the usual practice to make a complete turn or ring 111 the end of. the w re,
withpliers, or other like tool, then thread the rlng over a stud or shank of a screw and then clamp the wire ring between the screw head, or nut, and a relatively stationary part, to secure it to the terminal. This is,
in many situations, a difficult operation that means projecting from the part to be rothe end of the wire will be bent or coiled tated on the said screw threaded part, to-
- ward the stationary part to overlie the remote side of the wire and twist it around the said shank to form a ring or coil. Any suitable means by which this maybe accomplished will come within the purview of my invention.
In the accompanying drawings, in which I illustrate several forms for a clearer disclosure of my invention, 10 is an insulating block of slate, marble, or the like, such as that of which instrument bases or switch boards are composed, upon which the terminals of electrical instruments are to be located.
11 is a perforation in the relatively stationary clamping member, and 12 is a metal, interiorly threaded, sleeve provided with a flange 13 that is, in this example, secured in the base 10 by means of a screw 1,4.
To provide a larger surface for contact with the base 10, I show a washer 15, underlying the flange 13 and encompassing the sleeve 12. The flange 13 is perforated, as at 16, 16 or 16 in the several variations. The sleeve 12 may be of angular or other shape to prevent it from turning in the hole 11, or a plate 17 may engage the flange 13, as at 18, or 18, to prevent the sleeve from turning. Any suitable means will answer the purpose.
.In the particular form shown in Figs. 1. 2,
Fig. 4, consists of the shank 21 having a head comprising a flat central portion and oppositely downturned edge portions 2323 each inclined on its trailing side, as at 24., to permit the screw to be turned back without engaging the wire. The head 25, of the screw, may be and preferably is, an integral part of the shank. The screw 21 is provided with two oppositely disposed abrupt shoulders 2626 for engagement with the wire, either one of which may be used to turn' it around the shank of the screw. The shoulders 2626 extend downwardly less distances than the thickness of the wire. When the screw is placed in the threaded perforation in the sleeve 12 and turned inwardly thereinto, one of the shou1- ders 26 will engage the straight end of the wire, as it is shown at 20 in Fig. 3. The wire first having been inserted through the perforation 19 and through the perforation 16 in the flange 13 and beyond the shank 21 of the screw. In turning the screw into the screw threaded perforation of the sleeve 12 one of the abrupt shoulders 26, on the head of the screw, will encounter the wire 20 and will turn the end thereof around the shank or stud 21, as shown in dotted lines in Fig. 3, as at 27, and as shown in elevation in full lines in Fig. 2. Just about the time that the active or engaged abrupt shoulder 26 has made a complete revolution, the-flat base 22 of the screw head, will rest firmly upon the side surface of the end ring of the wire and clamp it to the flange 13 and the wire will be laterally confined around the shank 21 between the two downturned portions 23-23, and therefore cannot slip outwardly away from the shank 21. The parts 23-23 being of less depth than thediameter of the wire, they will not prevent the flat clamping portion 22 of the screw head from tightly clamping the wire ring that has thus been turned around the screw shank:
Fig. shows how my binding clamp may be used in connection with a bar or plate 28, which is perforated and screw threaded, for a shank 29 of a screw. It is slotted, at the end, as at 30, for insertion of a wire, to hold it just as the wire is held when placed in the perforation 1616 of the other figures. The screw is provided with a laterally extended flange 30, preferably integral with the head. 31 and the shank 29, and radially separated at one or more points, and downturned, as at 32, to provide one or more projections or shoulders similar in character to the projection 26, of the screw 21. The downwardly directed projection 32, from the flange 30, is not so long as the thickness of the wire, but when the wire is placed in the slot 30, in the manner shown in Fig. 3, the projection 32 will engage the wire and twist, or turn it one turn around the shank 29 of the screw and just about the time the ring is-thus formed in the end of the wire it will be clamped between the flange 30' and the plate 28. A projection 34, similar in character'to the projection 26 of the screw 21, and 32 of the screw 29, may be placed under the head of a cap screw 33, as shown in Figs. 7 and 8. The projection 34 consists of a small stud placed in the underside of the hexagon head 35 of the screw, or it preferably may be an integral part of the head of the screw.
In Fig. 9 I have shown a screw threaded stud 37 surrounded by a screw threaded nut 38, and a projection 39 on the under side of the nut. Instead of using a perforation or slot for holding the wire 20 in intimate contact with the stud or shank of the screw in any case, I may provide a small stud 40 to project from a fixed part of the clamp which is substantially equivalent in effect to the slots 16 or 30 for this purpose, to which reference has heretofore been made. It will be apparent that the device shown in Fig. 9 will perform the same functions in the same manner, by the use of a nut and stud, as is accomplished by the head and shank of a screw or bolt.
While I have herein shown several forms which my invention make take, it is evident that it is susceptible of further modifications within the scope of the appended claims.
Having described my invention, what I I claim is 1. A wire coiling and binding clamp comprising a rotatable screw threaded member having a part for overlying and clamping the w1re to a relatively stationary part a part or projection for engaging the w1re extending from said clamping member and of length less than the diameter'of the wire to be clamped and means for holding said wire near the axis of said rotatable member.
2. A wire coiling and binding clamp comprising a rotatable screw threaded member for overlying and clamping the wire to a relatively stationary part; a projection from said threaded member for bending the wire, extending toward the stationary part, and of length less than the diameter of the wire to be clamped, said stationary part providing a slot throu h which the wire is to be passed, for holding the wire near the axis of said rotatable member.
3. A wire coiling and binding clamp comprising a screw"; a projection extending parallel with the screw shank, from the under side of the head; a relatively stationary screw-threaded part, to receive the shank of the screw, and means on the stationary part for holding the wire near the shank of the screw, during the bending and clamping operation. 4:.
