TRACTION ATTACHMENT FOR CAR-WHEELS.

Specification of Letters Patent.

Patented Dec. 29, 1914:.

Application filed February 7, 1913. Serial No. 746,859.

To all whom it may concern Be it known that I, WILLIAM H. FIEN- .HOLD, a citizen of the United States, residing at Champaign, in the county of Champaign and State of Illinois, have invented new and useful Improvements in Tractlon -Attachments for Car-Wheels, of which the following is a specification.

My present invention relates especially to the class of traction attachment for car wheels, and the provision of a device of thls character which when attached provides the same with a smooth, broad engaging surface, thus enabling the wheel to be propelled upon dirt roads or highways of simllar nature.

Car wheels now in vogue are constructed to operate freely upon their supporting rails, and in carrying out this requirement, the rims of the same are provided with a peripheral flange to prevent lateral displacement. With this in view it is apparent that the wheels are unfit to travel upon dirt roads or other highways inasmuch as the flange cuts deeply into the roadbed.

My invention, as above set forth, provides a traction attachment which when connected to the wheels renders their engaging surfaces even, and comparatively broader than usual. From this it is recognized that the wheels are rendered capable of traveling on streets and roads without ruining the same, consequently rendering the cars suitable conveying wagons.

With the above and other objects in view my invention relates to such details of construction and in the arrangement and combination of parts as will be hereinafter fully described and specifically pointed out in the appended claim.

In describing my invention in detall reference will be had to the accompanylng drawings wherein is illustrated the preferred form of my invention and in which;

Figure 1 is a side elevation of an ordinary car wheel showing my invention disposed in connection therewith. Fig. 2 is an end elevation showing one section of the traction device in engagement therewith. Fig. 3 is a fragmentary view of my invention showing the method of attaching the sections at their ends. Fig. 4 is a sectional view taken on line 4- of Fig. 3. Fig. 5 is a sectional view of my device illustrating a detail in elevation.

Referring now more particularly to the drawings wherein is illustrated the preferred form of my invention, the numeral 10 designates the body portion of an ordinary car wheel which as is usual carries a hub 11. The hub mentioned is of the ordinary type and is adapted for engagement with an axle 12. The wheel is equipped with the usual tread 13 which has one of its margins extended to provide a peripheral flange 14:, which, as Well known, is adapted to abut the inner side of the head of the rail to prevent lateral displacement of the wheel.

While the Wheel above mentioned is of the usual form, it is to be understood that this has been shown merely to illustrate the application of the invention and that my inventlon is readily applicable in connection with other different forms, and from this it 1s apparent that the above form is merely shown to illustrate the applicability of the device.

My invention consists more essentially in a pair of semi-circular sections 15, the adjacent abutting edges of which are enlarged as shown at 16 to provide suitable reinforcements.

To facilitate the attachment of the sections about the rim and flange of the wheel, the same are provided with cut-out portions 17 and 18, respectively, the first mentioned receiving the enlarged rim of the wheel while the cut-out portion 18 receives the flange as illustrated. This construction enables the sections to be snugly disposed about the wheel, so that their enlarged ends may abut as illustrated in Fig. 1. To provide means for securing the adjacent ends of the section together, the enlargements upon one of the sections are provided with openings 17' and transverse apertures communicating therewith. The other enlargements are also provided with openings 18 and transverse apertures, the last mentioned openings being comparatively larger than the other opening for the reasons hereinafter mentioned. Bolts 19 are employed, which are disposed through the transverse apertures mentioned, the head portions of the bolts fitting in the openings 17 as is recognized. Nuts 20 are carried within the opening 18', and engage the bolt in such a manner as to securely draw the adjacent ends of the sections together. Semi-circucured in place a continuous broadened rim is formed. Any suitable means may be employed for securing the rim to the sections, but in the drawings I have shown bolts and nuts 22 and 28, respectively, serving this purpose. The bolts and nuts have proven very efficient in actual practice inasmuch as they prevent the accidental displacement of the rim portions, thus more readily assuring the entire operation of my invention.

The sections 15 mentioned, may be constructed of any suitable material, either molded or cast metal if desired. Each section 'may be cast as a Whole, thus reducing the cost of manufacture of the device to a minimum. The rim portions 21 are further preferably constructed of steel or the like metal, inasmuch as the same is constantly in engagement With the rough and uneven surfaces of the road.

The greatest of stress is laid upon the simplicity of my invention, and it is thought that the advantages and novel features of the same Will be comprehended from the foregoing disclosure.

Such changes as are permissible by the subjoined claim may be resorted to Without departing from the spirit of my invention.

Having thus fully described my invention, What I claim and desire to secure by Letters Patent is A device of the character described including a pair of semicircular sections adapted for detachable engagement With each other the inner periphery of said sections conforming to the contour of a car Wheel, and a rim carried on the outer periphery of said circular sections for the pur-- pose specified.
