WIRE CLAMP Filed June 8, 1927 mmvrox. 6715.972? 6. Coon Patented Get. 7, 1939 STATES PATENT orriee WIRE CLAMP Application filed June 8, 1927. Serial No. 197,412.
My invention relates to such tools as are adapted to be used in connection with work required on high-voltage transmission lines, and it refers especially to a tool of this type, by means of which the linemen are assisted in performing their work with a minimum of hazard While the current is on and without interruption of the service.
It is proposed by my present invention to provide a tool of this character with clamping jaws, arranged and insulated so as to be operated at a safe distance from a workman, so that, for instance, by'means of the tool, the workman may be able to hold a hot wire in place while the wire is being served; to
hold a jumper in place while it is being connected with a hot wire; or to hold a hot wire while it is being out.
Another object of my invention is to provide a tool of this character, which is simple in construction and operation and may be manufactuerd cheaply so as to be sold at a low price.
Other objects and advantages will appear .25 from the following detailed description of a preferred embodiment of the invention, which is illustrated in the accompanying drawings, it being understood that I reserve the right to make such changes and modifications in the form shown as come within the scope of the appended claims.
In the drawings:
Figure 1 is broken side elevation of a preferred embodiment of the wire clamp of my invention, the View showing the reciproeating clamping jaw in its normal position against the stationary jaw;
Figure'2 is a broken side elevation, similar to Figure l, but showing sectionally a line wire clamped between the jaws; and
Figure 3 is a view of the reciprocating jaw, as taken in a plane indicated by the line 33 in Figure 2, the rod upon which the jaw is mounted being broken.
The wire clamp of my invention is indi cated in the drawings as a whole by the numeral 1 and comprises a supporting rod or handle2, preferably of wood or some other suitable, light and strong insulating material having secured thereon at one end a ferrule 3 which has upwardly extending bracket 6 which is preferably made integral there with. The bracket is provided with hook 7 at its upper extremity. The tapered shank 4 of handle 2 is secured within the ferrule by means of rivet '5. A clamping jaw 8 is formed on, the bracket and extends at an angle thereto adjacent hook 7, the bracket being provided with teeth 9 extending transversely of the jaw, and the bracket has also thereon and extending from the same side thereof as the jaw, guide members 10 and 11, which are preferably forked in alignment with each other and with the jaw 8, the member 10 preferably being formed at the end of the ferrule 33, and the member 11 being formed between the jaw and the member 10, preferably somewhat nearer to the jaw than to the member 10. Within the forks of the members 10 and 11 and extending with its end therefrom is slidably fitted a rod 12, which is of non-circular shape so as to be prevented from rotating, cotters 13, which extend removably thru the respective members 10 and 11, are adapted to retain the rod within the forks of the members. The rod 12 is provided with a clamping member or jaw 14, arranged obliquely to the bracket 6 co-angular with the jaw 8, which is provided with teeth 15 adapted to register with the teeth 9 on the aw 8.
A pin 18 is fixed in the rod 12 and acts as a retaining and thrust member for washer 19 and is spaced below forked member 11 so as not to interfere with the complete closing to the axis ofthe supporting of the jaws. V1 ashers 19 and 20 arefreely mounted on rod 12 and the interposed, compression spring is adapted to normally retain the jaws in closed position.
To use the clamp 1 for holding a wire 17 or to release the ci amp from its engagement with a wire, the operator moves handle 35 and swings the long armizof the bell-crank lever'j toward the hand grip 32 for releasing the wire, thereby communicating the swinging motion of the lever thru the operating bar 22 to the rod 12 and thus moves the jaw 14 away from the jaw 8. The opposite move ment of the handle 35 will also result in an opposite movement of the jaws. This move *ment, of course, is easily accomplished, since the arm 34 is considerably longer than the arm 26.: It should also be observed that the clamp is easily guided into clamping en agernent with the wire 17 on account 0 the oblique relation of the jaws 8 and 14 to the supporting handle 2. The wire clamp may be suspendedion one of the line wires by means of hook 7 when not required. The hook, however, also serves for the purpose of holding a line wire in the groove of a pin-type insulator, while a'tie wire is being served.
I claim as'my invention:
