ELEVATINGi'v 0R SEPARATING JACK FOR ELECTRICAL CABLES OR WIRES.

' To all whom igfonay conccrm,

Be it known that I, THOMAS COPE, a citizen of the United States, residing in the city andcounty of Philadelphia, :State of Pennsylvania, have invented a new and jaws forming normally a wedge shaped body, and means for separating the jaws whereby when said body is inserted between the proper'wires-or cables and said means are operated, the relative wires or cables' are raised or separated thus rendering convenient access to the broken or impaired wires or cables when repairs or other treatment of the same may be accomplished.

The invention is satisfactorily illustrated` in the accompanying drawing, but the important instrumentallties thereof may be varied, and so 1t 1s to beunderstood that 'the invention is not limited to the specilic arrangement and organization shown anddescribed. v

Figure l represents a perspective view of a jack for wires or cables elevator or separator embodyiner my invention. Figs. 2 and il represent llingitudinal sections thereof with the members respectively 1n normal and operated conditions. Fig. 4: represents a partial plan view and partial horizontal section of the under member of the jack on an enlarged scale. Fig. 5 represents a perspective view of a' portion of a. detached member thereof. Fig. 6 represents a transverse section on line .fc-m Fig. 3. Fig. 7 represents a perspective -viewv of another member of the invention. Fig. 8 represents a longitudinal lsection of another form of the invention with its members in` normal condition. Fig; it) represents asimilar section with the members in operated condi-A tion. Fig. 10 represents a horizontal section on line'y-y Fig. 9. Fig. 11 represents a. transverse section on line z-z Fig. '9.

Similar letters of'reference indicate corresponding parts 1n the figures.

Referring to the drawings. lA designates y the` body of the device, the same comprising the stationary jaw C, the movable jaw B and the toggle levers D `intermediate of said jaws, one limb of each of said levers being pivotally lconnectedwith the ears E' on the jaw B, and the` other limb of each of which is slidingly connected with the ways F on the jaw C; Depending fronrthe jaw B arev the shoes G and rising from the jaw C are the shoes H, said shoes being adapted to contact, the contacting faces being inclined or wedge shaped, as will be referred to more fully hereafter. Y

J designates a bar or rod adapted to impart draft to the jaw A, the same being vpivot'a'llyy connected at its forward end with *the ear K', the lattenbeing secured to the undersidefof the jaw B. ,The rear end of said bar is pivotally connected with the elevis L, the latter having swiveled to it, the end of the screw M, on which is tted the nut N, the inner face of which is concave and has a bearing in a conical recess P iormed in the rear wall Q, of the jaw C by which'provision said screwis enabled to change its position angularly with the motions of the bar J, as plainly illustrated in Figs. 2 and 3. The screw M is provided withA a head lt for attachment of 'a suitable handle whereby the former may be rotated lVhen the parts are in' position shown in Figs. l` and 2, the device is inserted between `opposite banks or tiers of cables or wires where access to a broken cable or wire, is

desired, the device resting on what may be termed the under -rows or sets of cables or wires as its support.

operated whereby the bar J draws the jaw B in the present case to the right. The shoes G then ride on the shoes H and impart a certain elevation to said jaw B. As the front limbs D of the toggle D follow the motion of said jaw, the rear limbs D2 slide rearwardly in the ways F and so allow said front limbs D to in a radial direction to the required extent without bind- Then the screw is `may be termed the upper rows or sets of cables or wires, a space is provided thereby which permits access to the broken cablel or wire atthe existing place adjacent to the device where the same occurs.

When the screw is rotated in reverse di-l rection the bar .I advances the jaw B to the front when the movable members assume their normal positions and said jaw lowers and isv seated on the jaw C. When the device is closed again, as shown in Figs. 1 and 2, the bar J may be disconnected from the jaw B and removed with the clevis L, the screw M, and the nut N fromtthe rear wall Q of the jaw C, and in lieu of said screw and bar, I may employ the rope or cable T which is connected with the ear K and adapted to bel wound around the roller U which is mounted on the wall Q and which by its rotation serves to cause the draft imparted to the rope'or cable T to move the' jaw B to the right when said jaw begins its elevation as in the previous case.

The limbs D2 of the toggles D and openings in the ways F which receive said limbs are rhomboidal in cross section, see Fig. 5, so that while said limbs' may slide freely in said ways they are prevented from rising therein and so cause the toggle levers and l the jaws to remain connected.

In Figs. 8, 9, 10 and 11, I show a con--` struction similar in general respects to that of the previous figures excepting that each jaw has a single shoe G H respectively and excepting the toggle levers have each a single lower limb, the same being of the form of a slide D3 which rests on the base of the lower jaw B and is movable thereon and operative similar to the limbs D2 of the construction illustrated in tl1e.prcvious figures.

Having thus described my invention what I claim as new and desire to secure by Letters uPatent, is

1. In an elevating device of the character stat-ed, stationary and movable jaws, and

longitudinally movable swiveled screw means connected with said jaws adapted to impart longitudinal draft to the movable jaws.

2. In an elevating device of the character.

-ing means lnterposed between the same adapted to separate one jaw from another lirstby draftl on said jaw, and next by with said jaws.

4. In an elevating device of the character stated, stationary and movable jaws, means connected with Vsaid jaws for imparting 1ongitudinal draft to the movable jaw, means for primarily separating the movable jaw from the stationary jaw,and swiveled screw radial action of a lever which is connected means for further separating said movable i.

jaw to complete operative position.

5; In an elevating device of the character stated, stationary and movable jaws, means connected with said ja'ws for imparting longitudinal draft to the movable jaw, shoes with inclined faces on the jaws adapted for primarily separating themovable jaw, and a toggle 'lever having its` limbs connected with the opposite jaws and adapted for further separating the movable jaw to 'completeoperative position. v

6. In an elevating device of the character stated, stationary and movable jaws, means for imparting longitudinal draft to the movable jaw, and means for opening the latter, said first named means consisting of a 'draft bar, a rotatable screw, said bar being pivotally connected with said screw and with the movable jaw, and a nut on said screw, said nut having a turnable bearing on a member of the stationary jaw, said sorew passing freely through said member.
