RAIL-SWEEPING ATTACHMENT FOR STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 438,868, dated October 21, 1890.

Application filed March 17, 1890, Serial No. 34:4,271l (No model.)

To all whom it may concern:

Be it known that I, OTTO STERNoEn-BEYER, a citizen of the United States, residing at Carlstadt, Bergen county, New Jersey, have invented certainlmprovementsinRail-Sweeping Attachments for Street-Cars, of which the following is a specification.

This invention relates to means used in connection with street, tram, or similar ears for sweeping the tracks as the car moves along.

The broom or brooms, for I prefer to use two--one over each rail and on a common shaft-turn on substantially horizontal axes, and their shaft is mounted in a broom-frame which is hung at its other end on the carfaxle, means in the nature of a spring` or the like being employed to raise and hold up the frame and to keep the brooms normally out of contact with the rails. In this broom-carrying frame is pivotally mounted another supplementary or auxiliary frame, in which is rotatively mounted an auxiliary shaft, which is driven from the oar-axle through the medium of gears. The brooms are rotated from this auxiliary shaft through the medium of a belt or chain and sprocket-wheels. A spring or the like serves to rock the said auxiliary frame in such a manner as to disen gage the drivinggears and render them inoperative and to allow the broom-frame to be elevated by its spring. When the operator, by the means to be described, depresses the auxiliary frame, the first effect is to put the gears into engagement and set the brooms in motion, and then to depress the rotating brooms into contact with the track. Thus the means for putting the driving-gears into and out of engagement are to some extent independent of those for depressingthe brooms, and the two do not act altogether simultaneously, but rather succes` sively-that is to say, the auxiliary frame is independently depressed until the gears are in operative engagement-after which the further depression of said frame depresses the broom-frame also, and when the operator allows the broom-frame to rise it rises first to its full extent and then the auxiliary frame rises independently and disengages the gears.

In the accompanying drawings, which serve to illustrate my invention, Figure 1 is a plan of a portion of the floor-frame and wheels of a Streetcar provided with my improvements; and Fig. 2 is a sectional elevation of the same,

the plane of the section being indicated by the broken line in Fig. l.

a represents the floor-frame of the car, b the axles, and c the Wheels. The wheels run on track-rails d. On atransversely-arranged shaft e are fixed two circular brooms f, one over each track-rail. These brooms may be constructed in the same manner as brooms usually used in street-sweepers, or in any suitable manner. The shaft e is rotatively mounted in the ends of two arms g,which are mounted to turn about one of the axles hat g. Mounted in these arms near the axle is a rock-shafth, on which are secured two arms e', in which is rotatively mounted a shaft j, on which is fixed a pinion Zt, adapted to gear with a toothed wheel Z on the car-axle. The broom-shaft e is driven from the shaft j through the medium of sprocket-wheels m on the respective shafts and a chain belt n. Fixed to the boss of one of the arms e', or it may be fixed to the rock-shaft h independentlyof said arms, is an upwardly-projecting arm o, to which is attached one end of a disengaging-spring p, the other end of which is secured to the car. of which is shown in Fig. l) tends always to rock the shaft h and throw the pinion lo out of gear with the wheel l on the car-axle, and thus to stop the rotation of the brooms. An-

This spring (a portion only other spring q, attached at one end to the rock-shaft h and at its other end to the car, tends always to overcome the weight of the brooms and raise them off from the trackrails.

The brooms are pressed down upon the track-rails and the toothed wheels held in gear by means of a rod, chain, or other like connector r, which is attached at one end to the arm o, and at the other 'end to the one arm of a horizontal lever s, pivotally mounted under the car. From this lever another connector r extends to the platformof the oar, passes thence about a guide-sheave, and up through the platform, where it is provided with a ring to engage a hook t on the dashboard. When this connector r is drawn IOO taut and hooked fast, the shaft 7L is rocked, the pinion Zt put into gear with the wheel Z, and the brooms depressed until they bear on the rails. The rocking of the shaft Zt is limited by arms u iixed thereon, the laterallybent ends of which are provided with stout setscrews, which impinge on the respective arms g, and thus depress said arms and the brooms carried thereby when the connector r is drawn taut, as represented in Fig. 2. The set-screws in the arms u are not essential; but they serve to regulate with accuracy the extent to which the teeth of the pinion 7c may enter between thelteeth of the wheel Z.

The arms g g constitute what I have called the broom-frame, and the rock-shaft h and armsi t' constitute what I have called the auxiliary frame. The shaft h being situated between the broom-shaft and the caraxle, it follows that when the auxiliary frame shall have been rocked until the pinion 7a is in gear with wheel Z and the set-screws in the arms u rest on the broom-frame then any further depression of the auxiliary frame will cause it and the broom-frame to move together.

Very little force will be needed to draw the connector r taut, and it may be applied in any desired manner, and when drawn taut may be secured in any convenient manner. W'hen the connector is disengaged, the spring p disengages the driving-gears, and the spring q raises the brooms clear of the rails. The spring 1J need not be very strong and the power of spring q need only bealittle in excess of that required to counterbalance the weight of the brooms and their appurtenances.

It will be obvious that the connectors r and r may be one orcontinuous, and that the device may be operated from one end of the car only; but I have shown the lever s provided with two operating rods, chains, or connectors r and r, coupled to its respective ends and extending to opposite ends of the car, respectively. This enables the sweeping mechanism to be put in operation from either end of the car at will. However, the lever s and connector r" may be omitted and the connectors or rods r and r be continuons, as before stated. If the levers be employed, its pivot bolt or pin c may be extended down to the proper distance to serve as a stop to limit the upward movement of the broom-shaft, as indicated in dotted lines in Fig. 2.

Vhichever way the car is run the brooms turn in a direction opposite to that of the wheels of the car.

Fig. 2 shows the fioor of the car in section; but the iioor is omitted from Fig. l, in order to show the mechanism beneath it.

Having thus described my invention, I claim- 1. In a rail-sweeping attachment for cars, the combination,with a broom-frame pivoted on the car-axle, and a rotatively-mounted broom carried by said frame, of a gear-wheel on the axle for driving said broom, arocking auxiliary frame pivoted in the broom-frame, an auxiliary shaft in said rocking frame geared to the broom-shaft, and a pinion on said auxiliary shaft adapted to be thrown into and out of engagement with the gearwheel on the axle by the rocking of said auxiliary frame, substantially as set forth.

' 2.
