THEOPHILUS P. CHANDLER, OF PHILADELPHIA, PENNSYLVANIA.

WIRE-SUPPORT.

Sp eeification ofLetters Patent.

Patented May 1 1, 1909.

Application filed July 14, 1908. Serial No. 443,524.

To all whom it may concern:

Be it known that I, THEOPHILUS P. CHAND- LER, a citizen of the United States, and resident of the city and county of Philadelphia, State of Pennsylvania, have invented an Im rovement in Tire-Supports, of which the f0 owing is a specification.

My invention has reference to electric and other wire supports and consists of certain im rovements which are fully set forth in the fol owing specification and shown in the accompanying drawings which form a part thereof.

The object of my invention is to provide a simple and efiioient device for supporting electric and other wires, more particularly for use in connection with electric railways, which may be attached to the wire in a positive manner so as to grip or hold it firmly and without the necessity of brazing, soldering or other permanent means of union.

My object is also to provide a construction of suspended wire support which is adapted for supporting the wires from above, below or laterally; and my invention is more particularly directed to the immediate means by which the wire is supported, rather than the particular specific use to which it may be applied when employed in commercial use.

The invention is an improvement upon the class of suspension device set out in Letters Patent No. 779,640 dated. January 10, 1905, and while embodying the great advantages of the construction therein set out also combine with them additional features of construction which secure greater strength and more perfect construction.

My invention consists in a support for an electric or other wire comprising two clam ing body parts united in the direction of t e length of the wire, said arts being provided with oppositely grooved portions for inclosing the sides of the wire and also with interlocking portions for reventing the spreading apart of the two 0 amping body parts and combined with detachable means for uniting the two parts in their interlocking engagement.

My invention further consists in the said wire support above specified when the opposite ends of the respective clamping parts are formed with additional grooved portion oppositely directed to the grooved body parts and an oblique entrance between the two said grooved portions of each of the clamping parts, whereby the said parts may be first placed obliquely over the wire and the oppositely directed grooves of each clamping portion made to grip the wire from opposite sides by bringing them into alinement with the wire, so that not only is the wire gripped between the two clamping parts but it is also gripped between the oppositely directed grooved portions on each of the clamping parts.

My invention also comprehends details of construction which, together with the features above s ecified will be better understood by re erence to the drawings, in

which?- Figure 1 is a side elevation of a conductor support embodying my invention; Fig. 2 is a plan view of the same; Fig. 3 is an inverted view of the same; Fig. 4 is a cross section of thesame; Fig. 5 is a View similar to Fig. 3 during the application of the supporting parts; Fig. 6 is an inverted view showing how the clamping parts are applied; Figs. 7 and 8 are end views showing my invention applied to conductors of different cross section; Fig. 9 is an elevation of a modification of my invention when the conductor is supported from below Fig. 10 is a plan view of the same, and Fig. 1 1 is'a perspective view of another modification of my invention.

A and B are two parts between which electric conductor F is gripped. These two parts are of similar construction and when placed into engaging position they interlock with each other both vertically and laterally and firmly hold the conductor without the necessity of soldering or brazing. These parts A and B are of considerable length where they engage the conductor and also have contracted necks, which when brought together form a screw threaded hub C over which the screwthreaded sleeve D is placed and by which the parts A and B are locked together. This hub C may also have an in ternal screwthreaded hole for reception of a bolt or screw L by which the suspending device maybe attached to a support. InFig. 1 this screw L is held in the insulator N, such as attached to cross wires in electric railways. In Fig. 9 the bolt L is employed as the means of clamping the conductor support A B upon an arm N of any permanent fixture such as a cross arm or bracket of a pole. The parts A and B have their opposing lower parts internally grooved as at E to receive and clamp the conductor F between them. The opposite ends of the parts A B are respectively provided with parts A and B whicharealso grooved andfitted upon the facespfthe conductor F opposite to those gripped by the grooves of the corresponding body-parts A and B. As these end portions A B extencL to both sides ofthe conductor the;grooved part E on one side is cut away as at K and the grooved parts A and B are cut away as at K so as to form. a wide throat J for rec-cp tion of the conductor F to eachof'the parts A and B.

"To apply the parts A and B, they-are-first placed. diagonally across the con ductor -Fvas shown in Fig. 6, then-pressed uporrthe-conductor and-subsequently turned into alinement therewith as shown in Fig. 5,;and

ultimately forced tightly against the conductor and pushed together endwiseuntil they engage as in igs. '1, 2 and 3. In this condition, the parts A and 'B -willdirectly clamp grooved parts'in the same transverse-ahnethe conductor F between their ment, and the end parts A and B will clamp the-conductor fro n opposite sides-and-also respectively in opposite directions to pthe main body-parts A B. In other words, the parts A and A grip the conductor upon opposite sides; and likewise, the parts B B grip the conductor upon opposlte -sides. From this, it will be seen'that each. of the two parts AB ofthe-support will individually sustain the conductorand thatbothof the said parts together grip the conductor-1n the same transverse plane.

To lock-the two parts A B together adj acent to the conductor, I provide each of the said parts witha vertical tongue H and-a longitudinal tongue lat one end and with corresponding vertical undercut portions H and reeessesl on the other end, whereby the tongues of each of the said parts AB will 'fit into the undercut portion andrecesses of-the other ofsaid'parts. The verticaltongues- H and undercutsH interlock the-parts A B- to- ;gether in a horizontal plane and'the tongues I and recesses I interlock the-parts A 'B-together both vertically and laterally. It/is evident that either the par-ts H H or the parts I I may be omitted if desired; and more broadly considering -my invention, both of said sets of parts H'Hand l-lmay It is also evident that ends, they may be interlocked at oneend only, as preferred.

In Figs. 1 1306 inclusive I -have shown -n1y invention adapted as a hanger suclras may be used 111 'electrlc' railways, whereas I mF- -gs.

"the parts A-Bmay extend from-the conduc- -,,t0r inanydirection desired.

InFigs. 7 and 8, I have shown the support -;having the groovedportions E shaped to engage a grooved form of conductor. While it isrrnost desirable to have the surface of the JLOIldllCtOl F exposed continuously along its oconitact surface, this is not essential as the parts A B may be extended so as to envelop to a greater or'less extent the conductor. While my invention is especially useful as a supporting device for suspended electric wires-01* conductors and-has been more" fully described 'inconnection with such use, I do -not restrict myself to-any-use-as the-supporting device may be used for wires or rods :adapted for ,any purpose. Wl hen con structed as in=Figs.- 9,*1-0'and1-1it is especially well adapted for use of'the wire orrod 1 as a-raiil or" trackway as in :tel-phersystems and may or not, as desired, also conduct electricenergy.

"In Fig. '11 the body parts Axand B- are flanged and rest directly upon the cross arms or ties to which theyarebolted orspiked. l have used the term "conductor in abroad :senseirrespective:of whether it is intended for conveying current or not and hence do not Wish to-be lim-i-ted'inany manner-to specifie-app'lications of my invention.

t have'shown my invention in the form in which it is excellently adapted for comniercial use butl do. not'limit myself to the details as these in ay be modified-without departing-fromthe spirit of the invention.
