CABLE-SQ'EE ZEE.

Specification of Letters Patent.

Application. filed January '7,

York, have invented a new and ,improved- Cable-Sjueezcr, ot which the l'ollowing is a lull, clear, and exact description.

ln,thc forming of cables for suspension bridges and the like, in which each cable is lormed ol a plurality ol separate strands or wires bound together considerable ditlicultv,w

is often encountered in squeezing the strands` together, to form perfectly cylindrical cable, in lninging sull icicnt pressure to draw all strands into lirin engagement with e ch other7 and in holding the strands in position while the permanent clamps, wrappings or other inclosing means, are being placed in position.

rllhe obj cct of my invention is to provide a device which .may be easily and quickly applied to the mass of strands going to .make up the cable, which will torce them together into a perfectly cylindrical mass, and which may be very readily loosened and moved after the permanent securing means has been applied adjacent the point last squeezed into shape.

Reference is to be had to the accompanying drawings forming a part of this speciiication, in which similar characters et' reference indicate corresponding parts in all the tigures, and in whichY Figure 1 is an end view or' a cable squcezer constructed in accordance with my invention; Fig. 2 is a top plan view of the device shown in Fig. 1, the device for drawing the members together being broken away; F ig. 3 is a sectional view on the line 3-3 in Fig. 'l and Fig. -1 is a side elevation showing a inoditied forni o1 pressure-ap,lying means, parts being broken away and in section.

My improved cable squcczer is formed oll two separate semi-circular members 1() and 11, hinged together at one end and having means for forcing the opposite ends together. Each member has an inner bandv portion 12 presenting a smooth slnliace for direct contact with the strands or wires going to make up the cable, and outside of this inner band portion is an outer or reinforcing' portion 13 of any suitable forni in cross section. The

two members are secured together by a pivot pin 14, one of the members having two leaves or "aro ections 15 15 tor receiving Patented June 29, 1909.

1909. Serial No. 471,098.

,i-ixpt `pin, and the other member having t center leal or projection 16 disposed intermediate the two leaves or projections 15, 15. frs these hinged leaves or projections overlap and their inner surlaces lie in the arc ol' the same circle with the inner surlaces ol the two members, it is evident that there is no transverse line or groove extending entirely across the device at the hinge and into which any wire or strand could be lorced during the squeezing operation. 'lhe opposite end ol one member is provided with two lingers or projections 1T, 1T, extending on opposite sides ot a central 'linger or projection 1S carried by the other member. 'lhese overlapping i'ingers or projections 1T and 18 lie diametrically opposite to the hinge pin 14|- and when drawn past cach other to the proper extent, the inner surfaces of the two members and their m'erlap'ping projections at both the upper and the lower portions, lorm a perfect cyliiulrical bore or passage.

For drawing the two members together, each is provided with two upwardly-extending parallel lugs 19, 19 and cach pair of lugs supports a transverse pivot in 20. These lugs extend upwardly from t ieir respective members to such an extent that a line connecting the pivot pins 20 will lie entirely outside of the cylindrical bore or passage and beyond the overlapping iingers or projections 17 and 1S. Connecting these two pivot pins is a suitable means for drawing them toward each other and causing the two members to come to the position indicated in Fig. 1. 'In the specific form illustrated. in Fig. 17 this pressure-applying means includes two sections 21 and 22, each pivoted to its corresponding pivot pin 20, and one of said sections constituting or having a cylinder 23, and thc other constitutingl or having a piston 241 mounted within said cylinder. The section 21 having the cylinder 23 is ro vided with a cylinder head 25 and a glane 26 tor forming a tight joint about the piston rod portion ol the section 22. Adjacent the cylinder head 25 is an inlet 27, to which a suitable delivery pipe may be connected, and at the opposite end oi the cylinder is a small air-escape passage 28, through which air may enter or escape from the cylinder during the operation ol the device. In use, one ol the sections is detached from its pivot pin 20, the two members 10 and 11 are opened up on the hinge pin 14 and are the l brought together again about the large number of wires or strands going to make up the cable. TheV detached section is again secured to its pivot pin 20 and liquid is forced into the cylinder 23 under high pressure until the fingers or projections 17 and 18 have been overlapped, so that the inner surfaces of the two members lie in the are of the same circle. The permanent clamping means is then applied to the cable to retain the strands in position, the liquid is permitted to escape through the opening 27, and the cable squeezer is moved along the cable a short distance to a convenient point. lt is unnecessary to separate either of the sections from its member after the device has once been placed around the strands.

F or use with small cables or in center cores oi large'cables, a turnbuckle may be used in place of the hydraulic means illustrated in Fig. l. In Fig. 4 I have illustrated such a turnbuckla which includes two flat sections sure-applying means. Thus, the two meme bers in themselves constitute levers and permit oi' a greater pressure being applied to the strands ol the cable than is exerted at the pivot pins 20.

Having thus described claim as new and desire to Patent:

A cable squeezer, comprising two semicircular members having overlapping leaves or projections at one end, a hinge-pin extending through said leaves or projections, overlapping fingers diametrically opposed to sai l hinge pin, outwardly-extending lugs carried by said members yadjacent said ngers, and means for moving said members toward each other and about said hinge pin, said means including two sections, having their outer ends pivotally connected to the lugs of the members, said sections being in alinement with each other between the two connections, and said sections being longitudinally movable relatively to each other.

In testimony whereof l have signed my name to this specification in the presence of two subscribing lwitnesses.
