GEORGE HULL, OF BINGHAMTON, NEW YORK.

CAR-WH EEL.

SPECIFICATION ozmiznga part of Letters Patent No. 483,064, dated September 20, 1892.

Application tiled February 6,'1892. Serial No. 420,531. (N0 model-l To a/ZZ whom t may concern.-

Be it known that I, GEORGE HULL, of Binghamton, in the county of Broome and State of New York, have invented a new and Improved Oar-Wheel, of which the following is a full, clear, and exact description.

My invention relates to improvements in Acar-wheels; and the object. of my invention is to produce a simple form of wheel which may be secured to any car, butis especially adapted for use on street-cars, which by simply running it upon atrack will quickly and thoroughly clean the track from ice. It is well known that street-railway tracks are very liable to fill with water; that in a sudden cold snap the water freezes, so as to fill the grooves of the track, th us rendering traffic almost impossible, and that it is necessary to construct the wheel so that it will clean the groove of the track and also clean oft the tread ot' the track.

. With this end in View my invention consists in a car-wheel the construction of which will be hereinafter described and claimed.

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

Figure l is a broken side elevation, partly in section, of the wheel and the wheel-cleaner as applied to a car. Fig. 2 is a crosssection of a segment of a wheel. Fig. 3 is a broken detail side elevation of a modified means of securing the cutting-fiange and tread-cutters to the wheel; and Fig. 4 is abroken detail side elevation of the bearing-surface of the wheel, having a smooth tread and a cutting-flange.

The wheel 10 is of the same general shape as an ordinary car-Wheel and is journaled on the axle 11 of the car 12 in the usual way. rIhe tread 13 of the wheel is adapted to run upon the tread of the rail in the usual manner, and this portion of the wheel is provided with a series of transverse knives or teeth 14, which are not very deep, and which by contact with the tread of the rail are adapted to crush the ice upon the rail, and consequently clean the rail from ice. These knives or teeth are preferably formed integral with the wheel, as shown in Fig. 1; but they may be formed upon a separate band and shrunk upon the wheel, as shown in Fig. 3. The

wheel has a flange 15, which is adapted to eX tend downward into the groove of the rail, as shown in Fig. 2; but the ange instead of being solid, as is usually the case, is formed of a series of cutters 16, which may be ground to an edge or which may be made in the form of spurs. These cutters or spurs are preterably used in connection with the wheel having the toothed tread, as shown in Fig. 2; but they may be produced upon the wheel having a smooth tread 13a, as shown in Fig. 4.

In practice the wheel is journaled to the axle of the car, and by reference to Flg. 2 it will be seen that the knives 14 will bear upon the tread of the rail 22, while the cutters 16 will project downward into the groove of the rail, and when the wheel is revolved it will clean the ice from both parts of the rail. .It is not necessary to provide all the cars with wheels of this kind, as several of them may be provided with the wheels described, and by running these cars over the track the rails will be thoroughly cleaned.

To prevent any possible clogging of the teeth 14 and the cutters 16 ot' the wheels, the following cleaning mechanism is used, which mechanism is shown in Fig. 1.

Hangers 17 are suspended from the carbottom adjacent to the wheels, and secured to a shaft- 18, which is journaled in the hangers 17, are star-wheels 19, the teeth of which project between the cutters 16, and on the hubs 20 of the star-wheels are wire bristles 21,which are adapted to brush the teeth 14 and thoroughly clean them. The shaft 18 is revolved by means of the main wheels 10, the cutters 16 of which engage the teeth of the starwheels 19.

The wheels described above may be journaled to the axle of any kind of a car or they may be independently rotated,ii` desired, the essential thing being to bring the revolving wheels into contact with the rails.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the car-wheel having a flange formed of cutters, ot' a cleaner supported adjacent to the wheel and adapted to contact therewith, said cleaner being revolved by contact with the wheel, substantially as described.
