TROLLEY-POLE STAND.

full, clear, and exact description of the in-l vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specication.

My invention relates to trolley-stands for use on the cars of electric street or interurban railways, and has for its object the provision of a simple and improved device of this character, which is strong and. ldurable in its construction, inexpensive of manufacture, and efficient in its operation, and which is capable of having a trolley-pole easily and quickly attached to or removed therefrom.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,-

Figure 1 is a plan view of a trolley-stand embodying my invention. Fig. 2 is a side elevation thereof with parts broken away and in vertical section, and Fig. 3 is an enlarged section on the line w, 00 1n Fig. 1. v

Referring to the drawings, 1 designates the top or roof of a car to which is bolted or otherwise suitably secured a base-plate 2 having an annular flange 3 rising therefrom to provide a bearing box for the rotatable parts of the trolley-stand, as shown.

The turn-table of the stand is shown in the present instance as comprising a tableplate 4 having a ring 5 bolted or otherwise suitably secured to the under side thereof from the inner edge of which projects the cylindrical downwardly extending flange 6. This flange fits within the fiange 3 of the base for free rotary movements therein, and has an inwardly turned foot-flange 7, which rests upon ball-bearings 8 that work in registering races in said foot-flange and the Specification of Letters Patent.

base-plate 2. The turn-table is held in engagement with the base bearing 2 3 by a retaining annulus 9, which is secured to the base plate 2 within the foot-flange 7 by screws 10, or in any other suitable manner, and coperates with a set of ball-bearings 11 to hold said foot-flange in properly adjusted bearing engagement with the ballbearings 8. A shallow flange 12 projects from the under side of the ring 5 without the flange 6 and coperates therewith toV forni an annular socket into which the upper edge of the base flange 3 projects.

It is evident that the base 2 and table 4 with its depending flange 6 form a closed magazine'for the reception and retention of a suitable lubricant, which has free access to the bearings 8 and 11 to lubricate t-he same.

Rising from the table-plate 4 adjacent one side thereof are the two spaced bearing lugs 13 which cooperate with suitable bearing caps 14 to form bearings for the opposite end portions of a shaft 15. Fixed to the shaft 15 intermediate said bearing is a bracket or pole carrying member 16 to which the trolley-pole 17 is removably secured. To facilitate an easy and rapid engagement of a pole with or removal of the same from the bracket 16 with its trolleywheel in upright or proper wire engaging position the inner end of the pole has a clamp or split ring 18 rigidly secured thereto and from the opposite sides of which project studs or trunnions 19, which engage within the angled or substantially L-shaped bearing recesses 2O in lugs 21 arising from the forward end portion of the bracket 16.

The rear end of the bracket 16 is provided with a pole seat 22 to which the pole is securely clamped by a clamping member 23. This clamping member is hinged to the bracket, as at 24, and is held in clamped position by a hinge clamping bolt 25 and cooperating nut 26, as is apparent. This clamp may be quickly released and swung from pole engaging position by loosening the nut 26 sufficiently to permit the clamping bolt to be swung from between the coacting forked end of said clamp. The clamping of the pole by the cooperating clamping parts 22-23 holds the trunnions 19 of the pole in the upper angled ends of the slots 2O in which they work, thus adapting the trunnions 19, lugs 21, and clamps 22-23 to coperate to rigidly hold the pole against longitudinal movements relative to the bracket 16. Upon a release of the clamp 522-23 the pole can be moved relative to the bracket 16 to lower the trunnions 19 into the lower forwardly opening portions of the recesses to permit a forward movement of said trunnions from engagement with said recesses, as is apparent.

Peripherally grooved disks or sheaves 27 are carried at the outer ends of the shaft 15 wit-hout the bearings 13, and these sheaves zare partially encircled by coiled tension springs 28, These springs are shown as attachingat one end thereof to lugs 29 provided in the peripheries of the respective sheaves, and thence extend forward and downward around the sheaves, and are swiveled at their opposite ends in any suitable manner to tension adjust-ing screws 30. The screws 30 thread through the end portions Vof a block or cross piece 31 which is mounted upon the table 4 adjacent its rear Y edge. It is evident that the springs 28 cooperate with the sheaves 27 to. hold the pole 17 yieldingly elevated in position for its trolley-wheel to engage a trolley-wire.

It is apparent that I have provided a simple and eflicient trolley-stand which is strong and vinexpensive in its construction and adapted to permit a free horizontal turning ofa pole relative to a car, and also to permit an easy and rapid removal from or engagement of a pole with the pole holding bracket thereof.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. A trolley stand comprising a base plate having an annular flange rising therefrom, a top plate having its marginal edge projected over said base flange and provided with two annular depending flanges which coperate to form an annular channel for receiving the upper edge of the base flange, the inner of said depending flanges having f its lower edge turned inwardly to form a foot flange, ball bearings between said foot flange and base plate and a retaining member removably secured to the base plate within said foot flange and having its outer edge projecting over and in ball bearing contact with said foot flange, and pole carrying means oscillatingly mounted on said top plate. y

2. A trolley stand comprising a base plate having an annular flange rising therefrom, a ring-like member mounted over said flange and pole and having a pair of spaced annular flanges depending therefrom to provide a socket for the base flange to work in, the inner of said flanges projecting downwardly within the base flange and having its lower edge angled inwardly to provide a foot flange, ball bearings between said foot flange and base plate, an annular member removably secured to the base plate within said foot flange and having its outer edge projecting over the foot flange to hold it to its seat upon the base plate, a top plate bolted to said annular member to coperate therewith to form a turn-table, carrying means oscillatingly mounted on said top plate.

3.
