CLAMP. APPLICATION FILED MAR.16, 190Gx A TTORNE Y5 Jo o/,1 whom; it Wm, concern) "iiir isemeeop i the United States, residing at Littles tdwiifin thec'ounty of Adams and State of Pennsylvania, have i-nvented'a new and'use "i'ul Clampmfwhiclfthe following is a 'specification! '1 w 1 This invention relates to devices employed ticularly'ferclampingtwo wires.

The device'ina'y be employed for clamping for elamping' twobodies together, morepartogether'the ends of two wires, for clamping two vwires intermediate the ends, 'for "coup 'li'n'g two wires'in 'tran-s-verse relations, and? the .likeZ-C' i 1 P 1 i r The devide may be employed for connectiiig teleg'raph, -telephone, or similar wires .in

couple two wires either at their ad'acentends 05- or intermediate the same, as will e obvious.

In Figs.- 3,- 4, 5, and 9 there is shown the clamping device arranged for supporting stranthwiresupon fence-posts, and n this arrangement the ends of theiouter plate are of r m greater'length than the inner'plate and di verge, as at 23 24, for hearing against the W guy-wi s 1 i and with a bridging-wireill cou ling a pair post represented at 25. In the arrangement shown in Figs. 3, 4, and 5'one wire only will be required for the plates, (represented at 26,) this single wire being attached at the ends to the iost 25 and extending through a plurality oi the pairs of clamping-plates, there being as many ofthe pairs of clam ingplates as there are stramhwires27, the utter passing through transverse apertures in the plates, preferably between the clamping. iolts 28, as shown. By this simple "means the strand-wires are firmly supported in position relative to the post.

in Fig. lithe-manner of employing the improved claniping device for suspending a cable irom -a stay-wire is shown, the staywire being represented at 29, the cable at 30,

of the clamping-p ates disposer ypon the stay-wire with a )air of the clamping-plates disposed upon t e cable, the latter necessarily larger than the clamping-plates upon the stay-wire to correspond to thegincreasing sire of the cable.

lin Figs. 7 andS the device is shown provided with three oi; the clamping-bolts, which arrangement, will be employed where it is desired to'eou ple the wires with greater firmness or where the wires are subjected to abnormal strains.

The device is simple in construction, can i he inexpensively manufactured, readily a'pplied, and will hold the wires against all '(llfiplacements so long as-the holding means 128 are not entirely detached.

lit will be obvious by this anangemtmt l that when'bolts are employed as the securing means :the binding-nuts may he loosened or l almost entirely removed without danger of l the displacement of the wire, as thd'plates cannot be separated solong as the bolts are in amsitien through the plates. 3 n :Fig. it) another form ol'post is shown combined with theinrproved clamping devices, the post'bc'mg cmistrueted from an elongated, U-shaped rod '32 of suflicient strength, with the spaced ends inserted into the ground or into a suitable supporting-base and with the clamping devices embracing the spaced sides of the rod with a central aper: turc to receive the strand-wire 27. PM clamping devices are substantially the same as shown in Figs. 7 and 8, except that they are larger and wider, as the U-shaped rod 32 is of larger gage and with the sides spaced farther apart, but otherwise the constructhm is substantially the same.

Havin thus described the invention, wha't iselaiincr is l. A device of the character described comprising an inner and an outer plate, said plates being oppositely disposed and the inner plate having its end portions op iositely bowed and fitting snugly within the hendof the outer plate, and clamping means extending through the inner and outer plates between their bends and terminals.

2. A device of the character described comprising an inner and an outer plate, said lates being oppositely disposed and each iblded at the center, the inner plate having its terminals bowed in opposite directions to constitute clanrping-jaws fitting snugly within the bend of the outer date, said plates having alining apertures therein between their bends and terminals, and a clamping device extending through the apertures.

3. A device of the charlwtcr described 1 comprising a folded spring inner clampingplate, a folded spring outer clam iing-plate, and means extending through Hltit plates for contracting them.

in testimony that I claim the foregoing as my own I have hereto a'llixed my signature in the presence oi two witnesses. 1
