p U NIT WILLIAM SCHAAKE, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR I'O WESTINGHOUSE ELECTRIC & MANUFACTURING COMPANY, A. COBZPORATION- PENNSYLVANIA.
TEOLLEY-CO'NDUCTOR HANGER.
Application filed February 1, 15121. Serial 110.119.,116.
To all whom it may concern:
Be it known that I, WILLIAM SCHAAKE,& citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Trolley- Conductor Hangers, of which the following is a specification.
My invention relates to trolley-conductor hangers and it has for its object to provide a device of this character which shall be simple and durable in, construction, economical to manufacture and effective 1n -operation. r
In practicing my invention I provide a pair of pressed metal conductor-gripping ears or clamps each having a portion pressed out of a wall thereof to receive one of the initially straight freev ends of a uniform cylindrical hanger rod of substantially inverted U-shape. After'the insertion of the ends bodyingmy. invention, as viewed in .the di rection of, theconductor.
Fig. 2 is a view taken at right angles to Fig. 1, and i 2 Fig. 3 is a view taken along the line III-III of F 1g; 1.
Similar pressed-metal clamping members 1 and 2, having jaw portions 3 for engagement with a trolley conductor 1 and inwardly-bent engaging upper portions 5, are clamped in position by a screw bolt or r0- tatable member 6 that extends freely through the member 2 into a threaded portion 7 on the member 1. Portions 8 of the members 1 and 2 are formed by means of cuts or slits 9 therein and are pressed laterally inward for cooperation with upper and lower portions 10 and 11, respectively, to constitute approximately vertical sockets for the reception of ends 12 and 13 of a hanger rod or suspension member 11 that is of substantially inverted U-shape and is suspended from a messenger cable 15. Initially, the ends 12 and 13 of the hanger rod 11, that is preferably of uniform circular cross-sectional area throughout its length, and the portions 8, are substantially straight.
After the insertion of theends 12' and 13, in the sockets formed by the portions 8, 10 and 11, pressure is applied transversely to the longitudinal axis of the, hanger rod 11 to force the portions 8 toward positions in the planes of the portions .10 and l1. This action bends the ends 12'a'n'd -13 into substa'nti ally undulate-wave or corrug'ate. form, with porti'ons 16 bent slightly laterally between theportions 10 and 11 and, also, bends the iportions] 8 of the member's 1 and 2 against the concave sides of'the portions 16'. j After" the parts of the hanger'are assembled inrworking position, a further tightening of, the bolt 6v will not only tighten the hold of the clamping members 1 and 2 upon the trolley conductor'1, but will also tend to straighten out'the interlocking curved'portions of the suspension member 11 and the clamping members-T1 and 2 and thereby in: crease the grip of the members 1 and 2 upon both the trolleyeonductor'1 and the ends 12 and 13 ofthe suspension member 11. v
This structure withstands relatively great separating stresses and-provides-a very simple and economical device; I V v While I, have shown and described a preferred form ofmy; invention, I desire it to be understood that modifications may bemade therein by those skilled in the art without. departing fromthe spirit and scope of my invention as defined in the appended claims. f
I claim as my invention 2 1. A conductor hanger device comprising a hanger rod of substantially uniform crosssectional area throughout its length and a trolley-conductor clamp having a rod-receiving portion, said rod and said rod-receiving portion being held together by pressing the same after assembly.
2. A conductor hanger device comprising a hanger rod, and a conductor clamping member having rod-receiving means consisting of a plurality of portions longitudinally displaced along, and alternately disposed on opposite sides of, the rod, said rod and said means being formed and related to interlockingly engage each other.
3. A conductor hanger device comprising a hanger rod, and a conductor clamping member having rod-receiving means consisting of a plurality of portions longitudinally dispressed out of the plane of a Wa placed along, and alternately disposed on opposite sides of, the rod, said rod and said means being compressed laterally to interlockthe same together. 7
at. A trolley-conductorhanger device comprising a pressed-metal conductor-clamping member having a port-ion pressed out of the plane of a Wall thereof to therewith constitute rod-receiving means and a hanger rod having an end portion inserted in said re,- ceiving means, said end portion and said means being compressed laterally of the rod to form undulate-curve or corrugate interlockin portions in the rod and inthe clampi-Yig m er v V 5. A trolley conductoij hanger device comprising a pair of pressed-metal conductorclampingmembers each havin. a portion it thereof to therewith constitutea socket, and ahangerrod member of substantially inverted U shape having its free ends inserted in said sockets, said rod and said clamping members being compressed laterally opposite said sockets to form undulate-curve or c'orrugate portions in the rod for interlocking the same with respect to the clamping members.
6. A trolley-conductor hanger device coinprising a pair of pressed metal conductorclamping members each having a substantially vertical Wallv portion and a portion pressed out of the plane of the Wall to there- With constitute a vertical socket. and a hanger-rod member initially of substantially inverted U-shape having straight free ends for insertion in said sockets, said rod and said clamping members being compressed laterally opposite said sockets to form longitudinal-Wave or corrugate interlocking portions in the rod to position the clamping members.
7 A trolley-conductor hanger device comprising a pair of pressed-metal conductorolamping members each having a portion of arcuate form that is initially pressed out- Wardly from a blank Wall thereof to form a vertical socket and a hanger-rod member oi substantially inverted U-shape initially hav ing straight free ends for insertion in said sockets, said rod and said clamping members being pressed together opposite said sockets to form compound bends in the said free endsand to interlock said arcuate portions against said bends.
8. A conductor clamp comprising an :1;-
elongated member having a portion of sub stantially Wave shape and a conductor clamp having portions longitudinally spaced alternately on opposite sides of said member in interlocking relation thereto. I
9. A conductor hanger device comprising a suspension member, a plurality of trolley-- conductor clamping members through at least one of Which/ said suspension member is threaded and means for securing said clamping members one to another to more tightly grip said suspension member.
10. The combination with a trolley con ductor and a suspension member, of connectmembers slotted to receive the ends of said suspension member and a movable member for tightening the grip of said clamping members upon said conductor and said suspension member upon the actuation of said movable member. s I
11. The combination With a trolley con duo-tor and a suspension member, of connecting" means comprising a pair of clamping members through which the ends of said sue-- pension member are respectively threaded and a bolt for securing said clamping mem bers to said conductor and for increasing the grip upon said suspension member upon the tightening of said bolt.
In testimony whereof, I have hereunto subscribed my name this 29th day of January, 1921.
