CAR-HEATER. ,1

SPECIFICATION forming part of Letters Patent No. 224,194,'dated February 3, 1880.

Application filed October 15, 1879.

To all whom it may concern Be it known that 1 MICHAEL LIMPERT, of Pittsburg, Allegheny county, and State of Pennsylvai'lia, have invented a new Improvement in Heating Attachments for Cars, of which the following is a specification.

Figure 1 is a plan view of a car to which my improvement has been applied. Fig. 2 is a bottom view, partly in section. Fig. 3 is a sectional side elevation taken through the line 00 as, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish improved heating attachments for cars and other vehicles so constructed as to heat the floor of the vehicle and introduce a supply of warm fresh air into the vehicle.

A represents the frame of a car, which'frame is connected with the running gearing in the usual way. From the frame A are suspended one or more fire-boxes, B. The rear side of the fire box B is made close, to prevent the fire from being drawn back beneath the car. An air-space is formed in therear part of the fire-box B by a grate, G, to prevent the rear side of the firebox B from becoming unduly heated, the air passing in and out of the saidair-space through holes in the ends of the fire-box, as shown in Fig. 3. When only one fire-box B is used, it may be placed under the middle part of the car.

The fire-box B is covered with a sliding door, D, and a hinged door, E, an air-space being left between the said doors D E to prevent the upper. door, E, from becoming unduly heated. The upper door, E, forms a part of the floor of the platform or body of the car.

With the side of each fire-box B is connected the outer end of a pipe, F, the inner end of which is connected with a box, Gr, secured to the middle part of thecar-frame A, sothat the smoke and other products of combustion may pass from the fire-boxes B into the said box G. From the box G apipe, H, leads up through the car, as shown in Fig. 3, i to discharge the smoke and other products of combustion into the air. The pipe H may be placed at the center or in one corner of the car, as may be desired. The box G and the lower part of the pipe H are divided into two compartments by a partition, I, as shown in Figs. 1 and 2, to prevent the smoke from passing directly through the pipes F and box G from one fire-box B to the other and being discharged beneath the car. The box G is made with a sliding bottom, J, for convenience in cleaning the said box. The pipes F are inclosed in boxes K, from the upper sides of which openings lead into the car, which openings are provided with registers L, so that the entrance of heated air from the boxes K may be controlled as required. In openings in the bottom of the boxes K are placed registers M, so that the admission of cold air to the boxes K to be heated may be controlled as required. The pipe H should be inclosed with a casing or other guard, to prevent passengers from being burned by contact with the said pipe H.

I am aware that it is not new to adapt heaters to be placed under the platform or middle of cars, so as to transmit the heat through the floor, or to provide a heater placed in one corner of the car with a jacket communicating with the open air by ducts through the side of the car and exhausting by means of a fan under the car, or to supply the heater with cold air through a pipe extending through the top of the car and provided with a double hood, the air being passed through water in a tank, thence around the heater under the car to a register, through'whioh it enters the inside of the car.

I claim- The combination, on a car, with two fireboxes, one at each end, of the pipes F, the two separate boxes G G, and the divided pipe H, as and for the purpose specified.

' MICHAEL LIMPERT.
