PEARL SMITH, OF BARDWELL, KENTUCKY.
WIRE-WORKING TOOL.
Specification of Letters Patent.
Patented Feb. 18, 1908.
Application filed-August 5 1907. Serial No. 387079.
T 0 all whom it may concern:
Be it known that I, PEARL SMITH, a citizen of the United States, residing at Bardwell, in the county of Carlisle and State of Kentucky, have invented certain new and useful Improvements in Wire-Working Tools, of which the following is a specification.
This invention is a wire-working tool, and more particularly a hand-tool for coiling or twisting a piece of wire around another wire or other object, the invention being especially designed for applying insulator tie-wires.
The object of the invention is to provide a tool of this-kind which is simple in construction and which can be easily operated.
In the accompanying drawing Figure 1 is a perspective view of the tool. Fig. 2 is a sec tion on the line 22 of Fig. 1. Fig. 3 is a perspective view of a portion of the tool showing the same equipped with a modified form of wireholder.
The general structure of the tool is that of pliers, the handles of which are indicated at 5 and 6, respectively, and the jaws at 7. The handles are crossed and pivotally connected, and are normally held open by a spring 8. The jaws are also shaped to form a wirecutter 9.
The handle 5 carries a wire-twisting device comprising a wire-holding hook 10 mounted on a rotatable disk 11 having in its periphery ratchet-teeth 12. The ratchet-disk is secured to the handle 5 by means of a washer 13 fit ting in a central circular hole in said disk, and a plate 14 fitting on top of the washer and overlapping the disk. The washer 13 and plate 14 are fastened together by screws 15 which also screw into the handle 5 whereby said washer and plate are secured thereto. The ratchet-disk, the washer and the plate have radial slots 16 for a purpose to be hereinafter described, and adjacent these parts the handle 5' is enlarged as indicated at 17 sufficiently to form a support therefor. In the enlargement is a slot which is adapted to register with the slots 16.
The ratchet-teeth 12 are engageable by a pawl 18 fastened to the handle 6 and extending under a guide-plate 19 011 the handle 5.
A spring 20 secured to the handle 6 presses against the pawl and holds it in engagement with the ratchet-teeth 12. To the handle 5 is secured a spring 21 engaging the ratchetteeth 12 to prevent backward motion of the disk 11.
In use the ratchet-disk 11 is turned until the slots 16 register. placed in said slots, and the tie-wire is brought around the insulator and around the line-wire and placed in the hook 10. The handles 5 and 6 of the tool are then opened and closed which, by the engagement of the pawl 18 with the ratchet-teeth 12, rotates the ratchet-disk 11 whereby the tiewire is coiled or twisted around the linewire. The tie-wire will be held in the hook by the hand of the operator until the coil or twist is started. Both ends of the tie-wire are fastened in this manner.
In Fig. 3 is shown a modified form of wireholder comprising a base-plate 22 secured to the ratchet-disk 11, and having spring-jaws 23 between which the tie-wire will be placed. This form of wire-holder is to be used if a tight wind or twist is desired, and the form of holder first described will be used if a medium tight wind is desired.
The tool herein described is simple in construction, and easy to operate, and by its use the tie-wires can be quickly applied.
I claim:
A wire-working tool comprising a radially slotted ratchet-disk mounted on one of the handles, and having a central opening, wireholding means carried by the ratchet-disk, a radially slotted washer fitting in the aforesaid opening, a radially slotted plate fitting on the washer and overlapping the ratchetdisk, means for fastening the washer and plate to the handle, and a pawl on the other handle engageable with the ratchet disk.
In testimony whereof I aflix my signature, in presence of two witnesses.
PEARL SMITH.
