CONI)T STGR SUEPORT.

Application led September 5, 3.922.

T0 all en 7mm t may concern Be it lrnoWn that I, Homin i?. CHANDLER, a citizen of the United States of America, residing at Mansfield, in the county ot Richland and State of Ohio, have invented certain new and useful Improvements in Condue-'tor Supports, of which the following is a specification.

My invention relates to supports for con# ductors and has particular reference to that class oi supports by means of which a trolley conductor is suspended 'from an overhead support such as an insulated hanger, etc.

rllhe object olz my invention is to produce a simple, economical and reliable device which is easily and quickly installed. A

My invention resides in the construction, combination and relation of the various parts more fully hereinafter described and claimed.

In the accompanying drawings ll-igure l is a side view in elevation et my invention and shown as supporting a trolley conductor.

Fig. 2 is an end view of Fig. l.

Fig. 3 is a longitudinal sectional view of Fig. 2 on the line Fig. l is a transverse sectional view of Fig'. l on the line 4--4l- Fig. 5 is a transverse sectional view similar to Fig. 4l, but With the jaws open ready to receive a trolley conductor.

Fig. 6 is a sectional view on line -l of Fig. l of one oit the jaw or clamping menibers.

In the preferred construction embodying my invention shown in the various figures, employ a hanger H provided with a threaded Stud S. Secured to the stud by means of threads l is a aw 2 provided with a head 3 and means d at the lower end for engaging); the trolley conductor 5. ln combination with the jaw 2 is a jaw also provided with means 7 to cooperate with the means d for gripping' the conductor 5. The jaw 6 is also provided With an integrally formed annular collar 8 surrounding' the head 3 and provided with the external threads (l. The two jaw members are held in assembled position by 'forming a recess l0 in the collar and by rolling' or peening over the upper edge et the head 3 so as to form the annular lip ll which overlaps the collar 8 limiting the movement ot the jaw 6 relative to the au' 2 in one direction and ipareventing; the separation ot the Serial. No. 586,186.

parts in this direction. Mounted upon the collar 8 is an operating member l2 having threads to cooperate with the threads 9 and a projecting4 bead 13 which engages with the projectingmember le on the jaw 2. Either the collar 8 or the head 13 will prevent the separation of the jaws dependingon which one or' these elements, 8 or 13, engages With the member le. It will be noted that the tu'o'javs have, when assembled, a limited vertical or longitudinal movement.

is the member G is arranged to contact andA cooperate with the lower face oit the hanger lll and to pivot thereon7 l prefer to 'form the upper tace of the collar 8 With an arcuate contour as shown in Figli, although this is not necessary in the operation of my device.

in the installation o1" my device l prefer to mount the hanger H in position iirst and then secure the clamping device lto the hanger H by rotating` the clamping device in engagement with the stud S until the up per tace oit the head 3 engages with the lower face et the hanger H. lf, when this engagement takes place, the means 4 and 7 are vnot in alinement with the trolley Wire, vthe clamping' device is then rotated Sulliciently in the opposite direction to bring the means e and 7 into alinement with the trol ley Wire. To novv bring` the jaws into clamping engagement with the trolley conductor the operating member 12 is rotated until the bead 13 engages with the projecting member let. lli/1 hen this engagement takes place ful`- ther rotation of the operating memberl in the same direction will cause the jaw 6 to rise until some portion oi' the upper tace of the collar 8 engages with the lower face of the hanger lil. llt the trolley Wire 5 is Sulliciently large, the point of engagement is likely to be the lett hand corner L of the collar 8 and especially so 'it the top surface of the collar 8 is left flat instead oi" being curved as shown in Fig. 6. lit the upper `face is curved as shown in Fig. 6 the Contact may take place at various points along the upper surface depending upon the size oit the trolley Wire. .It Will usually be found that when the collar Si is brought into Contact With the lower face of the hanger lil. that the 1ne1nd and i' of the j'avvs 2 and o, respectively, will be in slight engagement with the conductor lff the rotation of the operating member l2 is conducted and in the same disok rection as previously, the jaw 6 will then be moved toward the jaw 2 about the point or' contact between the collar 8 and the hanger H as a fulcrum, and the conductor held in strong engagement between the members il and 7.

It will be seen by an inspectionoi Fig. 5 that my device will still operate and in a similar manner just described.r should the jaw 2 be secured to the hanger H, but in such a manner that the upper surface of the head 3 should rest a considerable distance below the lower surface of the hanger H. In that case the collar 8 would be moved upward as the operating member 12 was rotated until the collar 8 engaged with the annular lip 1 1 at the point K and further rotation ot' the member 12 would cause the jaw 6 to pivot about its engagement with the annular forcing the jaws into secure engagement with the conductor 5. v o

There are, of course, many' modifications which might be made from that herein disclosed and which would be obvious to one skilled in the art, and which modifications would fall within the scope of my invention, therefore, I do not wish to be limited otherwise than by my claims.

I claim:
