Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed December 12, 1906. Serial No. 347,409.

To all whom it may concern:

Be it known that I, ALBERT S. JANIN, a citizen of the United States, and a resident of the city of New York, Rosebank, borough of Richmond, in the county of Richmond and State of New York, have invented a new and improved Trolley, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a trolley of very simple, durable and eco nomic construction, wherein the frame is of such shape that in itself it acts asa guide for the wire to and from the contact roller, and as a fender for the gearing and joints of the frame.

Another purpose of the invention is to provide housed gearing for the members of the frame, whereby in all positions of the' frame the gearing is absolutely protected from entanglement with the trolley wire,

and in fact from any dangerous contact therewith.

A further purpose of the invention is to render the contact roller noiseless in action and to provide the contact roller with an accompanying adjustable scraper and means for holding the roller stationary when desired, and the scraper in any position to which it may'have been adjusted.

Another purpose of the invention is to provide a means whereby with perfect-safety to the operator the trolley may be adjusted from the inside of the car to any. position intermediate of the roof and the trolley wire and be held securely in adjusted position.

The invention consists in the novel constru'ction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved trolley; Fi 2 is a front elevation thereof and a section through the adjusting mechanism Fig. 3 is an enlarged side elevation of an end portion of the contact roller and ad jacent portion of the frame; Fig. 4 is an end view of the parts shown in Fig. 3; Fig. 5 is a of a car and a side elevation of the applied sectional side elevation of the upper portion trolley, the latter appearing in elevated position; Fig. 6 is a sectional front elevation of the contact roller Fig. 7 is an end view of the contact roller; Fig. Sis an outer face view of a bearing plate for a contact roller Fig. 9 is a sectional side elevation of the upper portion of a car and a side elevation of the applied trolley, the latter being illustrated as held closed to the roof of the car;

Fig. 10 is a plan view of the improved trolley and the portion of the roof of the car to which it is attached Fig. 11 is an edge view of one of the end guard plates for the contact roller and Fig. 12 is a view of the outer face of the said guard plate, and also shows in dotted lines an adjustable position of the plate carrying the scraper.

The trolley frame A is of that type known as a pivoted diamond frame, and consists of four upper members 10, two at each side, and four lower members 11, which are likewise arranged two at eachside. The upper members 10 are pivoted to a support to be hereinafter described, and the lower members 11 are pivoted to a base B adapted for attachment to the roof of the car C. The upper and the lower members 10 and 11 of the said frame are pivotally connected by means of rods 12, and the upper members 10 at each side of the center of the frame are braced by stay rods 13 and the corresponding lower members 11 of the frame are connected by corresponding stay rods 14 as is best shown in Fig. 2.

Springs 15 are attached to the end pivot rods 12 and to the lower stay rods 14, the springs from one end portion of the frame crossing those extending from the opposing end portion as is illustrated in Fig. 1. The lower ends of the lower members 11 of the frame are enlarged and are curved inwardly to a pivotal connection with uprights 16 from the ends of the base B, so that in the event a wire should possibly slip along the frame and should momentarily engage with the inner terminals 17 of the said lower members 11 of the frame, the Wire by reason of the shape of the said lower terminals 17 would be made to slip travel up the frame, and would in no manner interfere with segmental gears 18, which are made integral with the inner faces of the said lower terminals 17 of said lower members of the frame, the said gears 18 being made to mesh as is clearly shown in Fig. 1.

The frame A differs materially from frames of like type in that where the upper members 10 are pivotally connected with the lower members 11, the frame is rounded off, as is particularly shown at 19 in Fig- 1, so that no sharp or abrupt surfaces are presented to the wires that may engage with the frame, and

therefore the frame in its entirety is a guide for the wire. If the wire should engage with the upper members of the frame, the wire will be directed to the contact roller D to be hereinafter particularly described and should the wire engage with the lower member of the frame it will still be directed to the top and is absolutely prevented from interfering with the gear connections 18 between the lower members of the frame, as well as the gear connection of the frame, which action of the wire always sliding upward being due to the ovate form of the frame and the fact that there are no stops to be encountered.

The upper ends of the upper members of the frame A are upwardly and inwardly curved and are enlarged, and are inwardly as well as upwardly curved to a greater or lesser extent as is shown at 20 particularly in Figs. 3 and 4. Segmental gears 21 are made integral with or are attached to the upper enlarged ends of the upper frame members 10, and the upper ends of said upper frame members are pivotally attached by means of pivot bolts 22 or their equivalents to cheek pieces 24, which cheek pieces 24 are provided with suitable openings 23 for the reception of the said pivot bolts 22 as is illustrated in Fig. 12. Each cheek piece 24 is provided with a downwardly-curved, outu-*ardlyextending lip 25 at its upper end, and the meshing gears 21 of the said upper members 10 lie beneath and at each side of the lips 25, which act to carry a Wire over the gears 21, so as to prevent the possibility of the wire interfering with said gears. In fact, the lips 25 act as housings for the gears 21 but the upper enlargements 20 are so shaped that in all positions of the frame they act as guards for the gears and keep the wire in proper alinement.

Each cheek piece 24 is preferably of oval shape, as illustrated in Fig. 12, and is provided with a central opening 26, and an opening 27 adjacent to one side at its lower end. A hearing plate 28 is located-adjacent to the inner face of each cheek piece 24. These bearing plates 28, one of which 'is shown in Fig. 8, are of corresponding shape to the shape of the cheek pieces 24, and are preferably provided at the top and bottom of their outer faces with flanges 29 that engage the inner faces of the cheek pieces 24 as is best shown in Fig. Each bearing plate 28 is provided with a central'opening 30, through which a pivot bolt 31 extends from its corresponding cheek piece 24, the head of which bolt is designated as 39. Each bearing plate 28 is also provided with two apertures 32 and 32 located adjacent to the flanges 29, but the said openings 32 and-32 are diagonally opposite, as is also in Fig. 8, and with a transverse slot 35' that extends through from an outer edge to about the center of the plate above the central opening These slots in the bearing plates 28 are adapted toreceive the flattened outer end portions 36 of the shaft 37 for the contact roller D heretofore mentioned, so as to prevent said shaft 37 from turning; and said shaft 37 is also provided at each end with a threaded section 38, adapted to receive nuts 39 whereby to hold said shaft in position.

The contact roller D consists of a metal shell 40 in which shell a rubber cushion 41 is fitted, engaging with its inner face, said cushion being preferably of tubular form .and held to place by a coiled spring 42,

, bands orthe equivalent thereof, said cushion 41 being intended to deaden the sound when the roller is engaged with any object. At each end of the shell or body 40 of the roller,

an annular flange 43 is formed, and said flanges extend around disks 44 that are secured upon the end portions of the shaft 37, and the opposing faces of the disks 44 and flanges 43 are grooved to receive balls 45, so that the contact roller D turns upon ball or roller bearings. These balls or rollers 45 are introduced into their races through openings made in the disks 44, which openings are closed by plugs 46 having recesses in their peripheral surfaces. These plugs 46 are held in place by means of screws 47, since, the recesses that receive the said plugs do not extend through the disks, as is clearly shown in Fig. 6.

A scraper 48 is employed in connection with the contact roller D, being normally below the said. roller; and'said scraper has end flanges 49 that are secured to the inner faces of the bearing plates 28 by means of screws 50 or their equivalents, passed through said 'flanges into the aforesaid openings or apertures 34 in the bearing plates as is clearly shown in Fig. 3.

The contact roller D can be held stationary when desired so as to act in the capacity of a scraper, by introducing set screws 51, or the equivalents thereof, into one or both ends of the roller, which set screws are carried by the bearing plates 28 and ass through openings 28? in the plates and openings 28 in the heads of the roller D and it is evident that by loosening the screw 33 the bearing plates 28 can be turned on their pivots 31, so as to have the roller D above the scraper 48, which is the normal position of said parts, or that the scraper may be brought to a position above the roller. Thus scraper 48 acts independent of the roller D, but in all said conditions of use the pivots 31 are prevented from turn-- ing, due to the shape of their countersunk heads.

I desire it to be understood that the trolley may be drawn down in the customary man-' ner, .but preferably the trolley is operated by the mechanism shown in Figs. 2, 5, 9 and 10, which mechanism is operated from a point within the car. Said mechanism consists of substantially U-shaped bearings 52 located longitudinally of the roof of the car, one at each side of the base B as is particularly shown in Figs. 5 and 10 and the upright member at the outer end of each bearing 52 is provided with a horizontal inward extension 53 at or near its up er end. Each bearing 52 contains a spiral grooved drum 54, and these drums are mounted on a shaft 55, which shaft at its outer end is provided with a pinion 56, and the outer end portion of said shaft is divided and the divided parts are connected by a coupling 57 constructed of insulating material.

The pinion 56 is made to mesh with a gear 58, anc said gear 58 is secured to a shaft 59 that extends down through the clear story of the car as is shown in Figs. 5 and 9, and said shaft at its lower end is provided with a hand wheel 60, or its equivalent, whereby said shaft may be readily turned. The shaft 59 is also provided adjacent to its lower end with a ratchet wheel 61, engaged by a pawl 62 mounted upon a suitable support in the car. Chains 63 are secured to the lower connecting or brace bars 14, preferably at the central portion of said bars, and said chains are likewise connected with the spiral drums 54 at their outer end portions. Thus when the v shaft 59 is turned in one direction, the chains 63 will wind in the spiral grooves of the drums 54, and if desired the frame may be made to closely fold up upon the roof of the car as shown in Fig. 9 and be held in such position or the said frame may be partially closed as desired. When the frame is entirely or partly closed, and it is desired to open the same to bring the contact roller D in engagement with the line wire 64, as shown in Fig. 5, the chains 63 upon turning the shaft 59 in a suitable direction will unwind; and when the frame is opened to it's full extent the chains in commencing to wind in the oppositedirection on the drums will'be engaged by the projecting members 53 of the brackets in which the drums are mounted, and will be checked, thus notifying the operator that the frame has been fully opened.
