T 0 ab! whom t muy concern..-
Be it known that l, JOHN H. WILLIAMS, a citizen ol' the Uniivd States residing at Hast llevcland. in the roomy of Cuyahoga and State of Ohio. have invented new and useful improvements 1n Test-Clamps, ol which the following is a specification.
This invention is a line-ta iper for electric wires designed for use on ridier insulated or uninsulated Wires.
'l he object of the invention is to form an improved device having points which will cut through the insulation on insulated wires for the purpose of com listing a connection Without scraping or otherwise injuring the insulation. The invention illustrated in the accompanying drawings, in which- Figure l is a perspei-.tivo View of the implement applied. Fig. 2 is a side elevation thereof with the rubber sleeve removed, the sleeve bein used to rotect the operator in use on big -voltage ines. Fig. 3 is a top plan View.
Referring specifically to the drawings, the tapper lrasthe form ol' a sprin clamp having two members 6 and 7, preferaly made of llat spring metal. These are fastened together at the rear end by a screw 8, which also serves as a binding-post for the wirr 9. The members are halved and crossed, as at l0, forming two jaws 11 between which the wire or conductor is gripped. Une of these jaws is litted with a screw-plug 12, screwed into a hole in the jaw, and this plug has several needles i3 projecting therefrom toward the other flaw. A rubber sleeve 14 covers the roar or handle portion of the clamp for use on wires having dangerous currents.
The clamp bem applied to a wire, as shown in Fig. 1, tie members are pressed where they cross, which brings the jaws together and forces the needles 13, through the insulation of the wire into contact, the ourrent passing through the clamp and out the wire 9 te the other side of the circuit. The needles cause no injury to the insulation. The plurality of needles assures a good oontact, `because they will readily out through any insulation or non-conducting material which may cover the wire and give a number of oints of contact.
Fclainh- A line-tapgier comprising a pair of crossed spring mem ers having jaws one of Whioh has a penetrating-point projecting toward the other jaw, the members being secured together at their rear ends by a screw, and a Wire secured thereto by the screw. Y
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses. JOHN H. WILLIAMS. Witnesses:
