Patented Nov. 7, 1939 BRACKET FOR, TROLLEY RETRIEVERS Charles ll. Earll, deceased, late of York, Pa., by Maude M. Lambert, administratrix, York, Pa., assignor to Charles 1. Earl! Company, Inc., York,

Original application November 2, 1936, Serial No.

, 1 Claim. (c1. 191-93) This invention relates to improvements in brackets to be mounted on the dash of trolley vehicles and adapted to receive trolley retrievers of the type in which a drum adapted to receive 5 the trolley rope is mounted in an enclosed case which also encloses mechanism by which the drum is rotated under light tension to wind up and pay out rope under normal operation of the trolley and encloses mechanism by which the 10 drum is automatically operated to wind up the rope when the trolley has jumped the wire.

This application is a division of the application filed by Charles I. Earll, November 2, 1936, Serial No. 108,889, now Patent No. 2,131,223, dated Sept. 27, 1938.

An object of the present invention is to provide a construction adequately rigid to support trolley retrievers of the type just described, to provide against rattle and thus avoid the necessity of a tightening mechanism, and to meet the requirements of trackless trolley operation as distinguished from ordinary trolley operation.

Another requirement is that the bracket shall have a streamlined exterior form with rounded outer sides of increasing diameter joined to the dash with an outward flare of substantial radius.

With the objects stated and other objects hereinafter explained, the invention consists in 30 the construction hereinafter described and claimed.

Referring to the drawings:

Figure 1 is a lonigtudinal central sectional view of a complete trolley retriever embodying the invention.-

and side view of the back member on a reduced scale compared to Figure 1.

Figure 4 is a back view of the bracket which 40 is carried on the dash of the trolley car, or vehicle, to receive and retain the retriever.

Figure 5 is a fragmentary view of a retaining pin for locking the retriever in the bracket. The back of back member I of the retriever is provided with preferably three segmental annular .ribs 6 having grooves l in their outer faces adapted to interlock with segmental annular ribs 9 on the front face of bracket 8, these ribs 9 having inwardly extending portions fitting grooves l sothat when the back member is placed against Figures 2 and 3 are respectively a back View the bracket with its ribs 6 in position between ribs 9 of the bracket and then rotated to cause the segmental ribs to interlock, the back member Will be held firmly in position. To facilitate the entrance of the ribs 9 into the grooves 1, there is provided circular ledges 1 between the ribs 6 concentric with and of the same radius as the bottoms of the grooves I. To prevent rotation of the back member tending to unlock the segmental ribs the bracket is provided with locking pin ill to engage notch I2 in the periphery of the back member. Locking pin H! as shown is carried in a shell I ll slotted to permit movement of stud I! carried by the pin. In one side of this slot is formed a notch H into which stud ll may be turned to retain the pin against falling down while the retriever is being attached or removed. To prevent the back members from being turned too far in interlocking its ribs 6 with ribs 9 of the bracket a stop 6' is formed at one end of one of segmental ribs 6.

By means of the three grooved ribs 6 of the back member interlocking with the three ribs 9 of the bracket, there is provided a construction which has adequate rigidity to prevent injury to the retriever resulting from collisions and bumps of considerable severity, which has no rattle even when the clearance in the grooves is greater than that required for the easy attachment and detachment of the retriever, and thus avoid the necessity of a tightening mechanism to prevent rattle.

Bracket 8 as shown is ring shaped, and is provided on its rear face with a plurality of inwardly extending lugs 50, each having an opening for a screw or other means for securing it to the dash of the vehicle. The side 50 of one of the lugs serves with lug 6' of the back of the back member to stop the back member from being rotated too far in engaging it with the bracket.

Having thus described the invention, What is claimed is:

A support for a trolley retriever comprising a bracket ring continuing the substantially smooth rounded contour of the retriever casing, the

bracket ring being provided on its rear face with a plurality of inwardly extending lugs for attaching same to the dash of a vehicle, the front face of said ring being co-planar, three equally spaced inwardly extending annular ribs on the front face of the ring, a circular back member of the retriever mounted on the bracket ring and comprising a flanged plate having means for supporting portions of the retriever, an annular surface adapted to engage said front face of said ring, said plate having three equally spaced rearwardly extending portions being adapted to pass between the three ribs on the bracket ring and provided with grooves on the outer faces for slidably receiving the ribs of the bracket ring when rotated to cause the ribs to interlock, and means adapted to releasably lock said ring and back member together against relative rotation when said members are interlocked.
