MACHINE FOR DRESSING CAR-WHEELS.

SPECIFICATION forming part of Letters Patent No. 443,928, dated December 30, 1890.

Application filed June 12, 1890.

To all whom it may concern.-

Be it known that I, BENJAMIN J. ABBOTT, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Machines for Dressing Metals, of which the following is a specification, reference being had to the annexed drawings, illustrating the invention, in which- Figure 1 is a side elevation of a car-wheel and dressing-disk, the apparatus by which the car-wheel is heated before the application of the dressing-disk, and the apparatus for subjecting the car-wheel to cold water and the dressing-disk to cold air and forming an upward current for the escape of heat from the surfaces in contact; Fig. 2, a section of the housing of the disk on line 09,- Fig. 3, a horizontal section on line y.

This invention relatesto means in machines where a smooth metal surface is made to dress another metal surface for heating the metal to be dressed before applying the dressing-disk and in means for keeping the sur faces in contact from having too high a temperature.

The special machine to which this improvement is more particularly adapted is the one for dressing car-wheels in which the dressing-disk runs ata high rate of speed and the car-wheel at a much lower rate. In such work it is found that little or no progress can be made in dressing the car-wheel till it becomes quite warm. Therefore, to save the cost of running the disk against the carwheel to warm it, I provide means for heating it by a flame or other suitable means before the disk is applied to it. It is also found that both the car-wheel and disk become overheated before one wheel can be dressed. To remedy this I provide means for putting a blast of cold air onto the disk and cold water on the car-wheel. I also provide means for conducting off the heat in a great measure during the dressing process, as the whole is hereinafter fully described and shown.

Ais a side elevation of an ordinary carwheel to be dressed, the axle of which is shown at A and is supposed to be rotated by the usual well-known means.

The dressing-disk in side elevation is shown Serial No.355,l62. (No model.)

at B, and its shaft B is supposed to be connected with pulleys and. belts, whereby a proper velocity is imparted. Over the carwheel is placed a heating-chamber T, which is lined with fire-brick or other material known to withstand fire. From this chamber a flue J leads up through the roof 7 of the inclosure in which the machine is set, and the lower portion of the flue extends through a guide Y, that it may be elevated to permit a car-wheel to be placed under the heatingchamber or removed therefrom. Cords, weights 6, pulleys f, and balancing-weights hold the heating-chamber and its attached flue in any desired position to which they are moved. A cold-blast chamber E is made to project over the upper portion of the disk B, and it is provided wit-h a flue a, which also projects through the roof IV.

D R S is an oil-heater, which projects a flame 3 upon the car-wheel within the chamber T.

F represents an ordinary air force-pump, which by means of a pipe H puts air into a receiver G. A pipe M M M conducts the air through a cooler L and into the chamber E to cool the disk 13. A pipe I I I communicates with the receiver G and a vertical pipe K, and the latter pipe communicates with a horizontal pipe X, which extends into both fines Q and J, and by means of extensionpipes O P upward currents are formed in said fiues by the upward thrust of air. Apipe K communicates with the pipe X and pipe R, whereby a blast is given to the flame s. A vessel 0, containing cold water, is placed below the wheel A for the water to cool the wheel.

The operation is as follows: To place the car-wheel in position, lower the vessel 0 by means of the set-screw U, which secures its standard to the foundation V, and raise the heating-chamber T. Then leave the vessel 0 down and lower the heating-chamber to the position shown and shut the cocks at 0. Start the heater D R S and open cock d. WVhen the wheel A is sufficiently heated, put the disk to work, and so soon as it and the Wheel A become too hot put out the heater. Let the cold air in by pipe M M M and the air into pipes O P, whereby the heated air may escape and the cold air have its effect on the disk. Also elevate the vessel 0 to bring cold Water to the Wheel A.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a machine for dressing metal, an improvement for heating the metal to be dressed, consisting of an adjustable heating-chamber and an upwardly-projecting flue as a part thereof, a suitable heating device projecting a flame into the compartment, and an airblast to force the flame onto that portion of the Wheel Within the chamber, as specified.

2. In a machine for dressing metal, an improvement for cooling the disk, consisting of ahood covering the upper portion of the same and the hood provided with a fiue, in combination with an air-pump, an air-receiver, an air-cooling chamber, and pipes for conducting the cold-air blast into that portion of the disk Within the hood, as specified.

3. In combination With an air-pump, cooling-ohamber, and pipes for putting a cold blast onto the disk, an adjustable vessel to contain a cold fluid placed below the Wheel to be dressed, substantially as specified.

BENJAMIN J. ABBOTT.
