' SPECIFICATION forming part of Letters Patent No. 604,006, dated May 10, 1898.

Application filed August 14, 1897. Serial No. 648,226. (No model.)

To all whom it may concern: 7

Be it known that I, HENRY C. DUENSING, a citizen of the United States, residing at Beecher, in the county of Will and State of Illinois, have invented a new and useful Improvement in Traction-Wheels, of which the following is a specification. My invention relates to traction-wheels,and particularly to means for preventing the accumulation of snow and ice on the tread of the wheel. Its object is'to provide a construction in which the tread of a tractionfwheel maybe heated while the wheel is in motion, so as to prevent such accumulation. I attain this object by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is an elevation of a part of a traction-engine embodying my invention, showing part of the boiler and-one of the Wheels with steam connections. Fig. 2 is a vertical section on the line W W 'of Fig. 1 with the wheeltnrned so that the pipe isin a verti- Fig. 3 is a cross-section of the rim of the wheel, taken on the lineX Xof Fig. 1. Fig. 4 is a vertical section of part of the rim of the wheel, taken on the line Y Y of Fig. 2.

The traction-wheel is provided with a hollow rim formed by fastening an outer rim or casing 2 upon the inner rim 4, leaving the airtight compartment 1 between same. A gasket 3 extends around the wheel between the two rims on either side, the rims being fas tened together, compressing the gaskets, by

means of the bolts 14. The bolts 14 also serve to secure the rims to the spokes 15'.

The pipe 5, communicating with the compartment 1, is secured to the inner rim 4 and turns with the -wheel,'the lower part of the pipe revolving in its connection with the pipe 10. The connection between the pipes 5 and 10 comprises a stuffing-box 7 8. The pipe 5 is provided with ports 6, communicating with the pipe 10. The outer end of the pipe 5 is closed by a cap 9. I The pipe l0 communicateswith the boiler 11 and is provided with a cock 17 for controlling such communication.

The compartment 1 in the rim has therein a partition 13, near the pipe 5. On the side of the partition away from the pipe 5 a' cock 12 is provided for discharging the exhaust.

The pipes 5 and 10 are removably secured other side of the partition, where same conil denses' and where the exhaust maybe dis- 7 charged through the cook 12. v

The advantages of my device will also be readily understood. Heretofore much difliculty has been experienced with traction-en gines through the formation of ice on the tread of the wheel, especially Where the tread is provided with projection 18,, the ice either forming large lumps or forming a smooth sur face between the projections, and thus materially interfering with the movement and power of the wheel. this objection by preventing the formation of ice while the engine is in operation and also providing" convenient means for removing ice which may form upon the engine while same is not in use.

It will be seen that the details of construction may be considerably altered without departing from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A traction-wheel having a hollow airtight rim, with a partition 13 therein, and a discharge-cock on one side of said partition opening out of the rim, in combination with steam connections communicating with said rim on the opposite side of the partition, and adapted to convey steam orhot air into said My device overcomes rim. while the wheel is in motion, for the purposes specified. I

2. A traction wheel having a hollow airtight rim; in combination with a pipe 5 communicating therewith at one end, having its other end bent in line with the axle of the wheel, and having a port 6 therein; an airtight connection in which said other end is journaled; and a pipe 10 secured to said connection for conveying steam or hot air through the port 6 and into said rim, for the purposes specified.

3. :A traction rwheel having a hollow, airtight rim with a partition 13 therein, and a discharge-cock on one side of said partition its other end bent in line with the axle of the wheel and having a port 6 therein; an air-' tight connection in which said other end is journaled; and a pipe 10 secured to said connection for conveyin g steam or hot air through v the port 6 and into said riin, for the purposes specified.

4. A traction-Wheel having an inner rim 4 and an outer rim 2 secured to same and. grooved so as to form an air-tight compart-- ment between said rims, and a gasket 3 interf vening said rims on either side, in combination with steam connections, adapted to convvey steam or hot air into said compartment while the wheel is in motion, substantially as 20 and for the purposes specified.
