OPERATING MECHANISM FOR STREET-RAILWAY CARS.

SPECIFICATION forming part of Letters Patent N o. 557,853, dated'April *7, 1896. Application tiled October 8, 1895. Serial No. 565,017. (No model.)

To all whom, t may concern.-

Be it known that we, SAMUEL MEssIER, a citizen of the Dominion of Canada, and DAVID J. BORDEAUX, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Switch-Operating Mechanism for Street-Railway Cars, of which the following is a specification.

This invention relates to switch-operating devices for street-railway cars, the object being to provide improved devices of this class to be operated by a person on the car and which are adapted both to turn the switch-points and to clean ice, snow, and other obstructions from the inside of the rail; and the invention consists in the novel construction and arrangement of the several parts of the device, all as hereinafter fully described, and more particularly pointed out in the claims.

In the drawings forming part of this specification, Figure l is a side elevation of one end of a car having applied thereto switchoperating devices embodying our improvements, this figure showing certain parts in section to more clearly illustrate the construction thereof. Fig. 2 is a top plan view of the parts shown in Fig. l, the floor of the car being in this figure somewhat partly broken away. Figs. 3 and 4 are perspective views of the switch-operating devices separa-ted from the car and of a portion of the road-bed and rail and switch. Figs. 5 and 6 illustrate portions of a street-rail and switch parts and a part of the switch-operating device in relation thereto, all as hereinafter described.

In the drawings, A is the platform, and B is a portion of the truck of a street-car, P indicating the usual dasher thereon. On said truck B, directly opposite thereto or supported thereon through the medium of a supporting-bearing C, bolted thereto, is placed a post D, which is adapted to have a vertical and a reciprocatory rotary movement by means of devices hereinafter described. The lower end of said post D is fork-shaped, and between said fork elements aswitching-disk E, having a periphery of the form illustrated in the drawings, is hung, as shown, whereby it is adapted to rotate through contact with the rail 6 or with the switch devices hereinafter described. On the upper end of said post D is placed a swiveling yoke h, which is slot-ted to receive a leverJ, thelatter being pivotally attached to said yoke by a pin which passes through a slot 10 in said lever, whereby the said lever has the requisite freedom of motion in operating said post. The said postsupport C is provided with two vertical slots z' i2 within the walls of its perforation surrounding said post, and the latter is provided with a guide-pin 9, which engages in either one of said slots according to the position which the post may be brought to rotatively before moving the said switching-disk completely to a-n operative position relative to the switch devices of the road or to the rail thereof, the purpose of the engagement of said pin 9 with either one of said slots being to provide means for rigidly holding the said post and switching-disk in operative positions temporarily independently of the devices for operating the same,which are manipulated from the platform of the car. A spring e is applied to the said post D between said support C and the swivel-yoke h, which acts to lift said post and the switching-disk upwardly and maintain the same normally in an upward position, as in Figs. l and 3, said spring being compressed when the switch-operating devices are moved downward by the opera-tor. Y

A chain-sleeve f is iixed on said post D and has a chain-hook CZ, to which the operatingchain 8 is attached to prevent the latter from slipping on said sleeve. The said lever J is pivoted by one end to the truck B,that extends under the platform of the car nearly to the end thereof. A plunger in two parts K K2 (said parts being divided at ly, Fig. 3) extends through a sleeve a, fixed in the platform A. The lower section K2 of said plunger is pivotally attached to one end of said lever J, and the section K of said plunger, which has a head on it, as shown, rests by its weight on the upper extremity of said lower section K2. This construction of said plunger provides for removing the upper section thereof when the car-operator leaves his position, so that said switch devices cannot be inadvertently operated.

A rod Nwhose lower end is supported in IOO a yoke-frame 0, secured under the platform A, extends upward through the latter about to the upper edge of the dasher P and has its upper extremity squared, as shown in Fig. 4:, to receive a crank XV, the latter being removable at pleasure. Said crank has a fixed upturned handle part t2 and a pivoted handle part vzf,which has a lower arm extending along the face of said crank, the extremity of which extends through the crank and constitutes a pin s. A spring on said crank acts against a part of said handle part t to cause the end of said pin s to project beyond the under side of said crank. Said crank \V occupies the position relative to the switch devices illustrated in Figs. l and 2.

A perforated metallic segment R is bolted to the dasher P and has perforations therein to receive said pin s, whereby upon turning the rod N by means of said crank the rod is locked in any of three or more positions by the entrance of said pin into one of said perforations. By grasping the parts "v t2 of the crank, the part o; being pivotally attached to the crank, the said pin s is drawn upwardly and out of engagement with said segment R. Upon releasing the part 't said spring acts, provided the crank is in proper position, to carry the pin s into one of said perfor-ations in segment The said rod N has :fixed thereon a chain-sleeve M, substantially 'like said sleeve f on the said post D, and like said sleeve f it has a chain-hook c thereon for en- 1 gagement with the said chain S, to the end that the rotary movement of the rod N may result in a positive drawing action on said chain.

In Figs. 2, 5, and 6, 5 indicates a part of av street-railway rail, and 6 in said figures indi cates the switch-bed of said rail, and 7 the ordinary pivoted'or swinging switch-points.

The operation of the above-described de` vices is as follows: The adjustments of the lever J as to vertical movement produced by placing the foot of the operator on the footpost K are such that when the lever is op-v erated to move the post D and the switchingdisk E toward the rail 5 said disk will be carried downward only to such 'position as may be necessary to insure the engagement of its periphery between the rails 5 and the switch-point 7 or with the inside of said rail. Before Operating said lever J as just described, the operator, by turning the rod N, by seizing crank XV, turns the post D and the switching-disk E to one of the positions showm in Figs. 5 and 6, or to a position tangential to the side of said rail, for the purpose of engaging whichever side of the switchpoint 7 it may be necessary to do to give the car the proper direction on the track, and immediately that said switch-point has been operated, as desired, the lever J is freed to allow the spring e to lift said lever and the post D and the disk E up away from the rail, as shown in Figs. l and 3.

In using the above-described devices in connection with the disk E it is found that the latter is very useful when brought to the tangential position relative to the rail 5, as shown in Figs. 2 and 5, for removing ice, snow, and other obstructions from the inside of the rail, and when said disk is so used, and thus required to be held in the same posit-ion for a considerable time, the engagement of said pin 9 in the post D, which carries said disk E, with one of the slots t' t? assists, essentially, in rigidly retaining the said disk in the operative position shown in Figs. 2 and 5 relative to rail 5, the said disk then acting as a rolling scraper or cutter having a shearing action against the side of the rail. The arrangement of said two slots for the reception of said pin 9 provides for holding the said disk E either in the position shown in Fig. 5 or that shown in Fig. G. It is obvious that the engagement of the pin .son the crank w with said segment R would tend to hold the said disk E more or less rigidly in one of the positions just referred to in connection with Figs. 5 or 6 but when the said disk is used to clean the rail it is desirable that it shall be under a rigid control and not subject to variations of position, which would be occasioned by the slackness of the chain S.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
