' SPECIFICATION kforming part of Letters Patent No. 372,779, datedrNovember 8, 1887.

Application filed January 30, 1886. Serial No. 190,370'. (No model.)

Beit known that I, HIRAM G. WILsoN, of the city of St. Louis and State of Missouri, vhave invented a new and useful Improvement 5 1n Heaters for Cars and other Vehicles while in Motion, of which the following is a speci' iication.

My invention relates to the heating of cars, but 1s adapted also to the heating of other 1o compartments.

The object of the invention is to provide i'or the warming of the floor of the car or other compartment, and to furnish a steady warm temperature throughout the oar, the heat berIhe ordinary way of heating cars by exposed pipes has a wellknown objection of unequal heating, making the heat too great in one place and too little 1n another. Attempts have been made herey2o tofore to remedy this difficulty; but, .so far as I am aware, the devices suggested have never come into use. These have. consisted oi' various devices for distributing hot air through the iioor of the car, and in some cases products of combustion have been passed into the airchamber underneath the iioor of the car and about its sides.

My invention consists in the special construction, as hereinafter described. I use ordinary heating-pipes to conduct the products of combustion, or any heating medium, and arrange them on the iioor of the car or other vehicle. These pipes may be two inches in diameten (more or less.) They are laid directly on the iioor of the car, and are covered with any suitable material to form a floor, the iioor having supports under it to form an airchamber, and the floor last' named-that is, the upper floor-is perforated throughout its 4o entire surface with holes one-quarter of an inch, or thereabout, in diameter, as shown in F1gures2 and 3. The iioormay be covered with carpet or matting, as may be desired. This will not interfere with the distribution of air. The heater may conveniently consist of a baseburner stove With up and down drafts, and this may be incased with asbestus or any suitable material to prevent radiation outward from the point of combustion, and the magashown in the zine may be placed at any point inside or outside' of the car.

As hereinafter described, I contemplate adding this door to cars already in use, or to cars built for the purpose, as a temporary or removable iioor over the ordinary door, and when this temporary iioor, with the heatingpipes, is in place the seats of the cars may be raised by the addition of an eXtra cushion. As above intimated, this same arrangement of devices may be applied to a room of a building.

The precise construction of my invention is accompanying drawings, in which 'l I Fig. 1 represents a plan of the floor; Fig. 2 a transverse section, Fig. 3 a longitudinal section, and Fig. 4 an inverted plan, thereof.

`In the drawings the permanent floor is represented at C, and is the door of the car or other equivalent structure of the ordinary forni. On this iioor is laid a series of supports, B. These consist of short pieces of scantling or other similar material. Ihey are arranged in interrupted or broken lines, as shown in the figures, so that they nowhere form a closed space, but leave a free circulation of air possible throughout the chamber between the upper and lower iioors. The upper or temporary floor is preferably made in sections of about three to tive feet, oi' any suitable iiooring material, and these sections are preferably attached to the supports B, so that the sections or the supports can be laid down or taken up together. The temporary iioor is perforated throughoutv its entire surface with holes to allow the passage of air from the heat` ing-chamber below up into the space above. The air-chamber between the upper andlower iioors is heated by the ilues or pipes D, which passlengthwise through the iioors from the heater, extending through the supports and being exposed to the air within the heatingchamber, so that the air is heated by contact with these pipes. Y

I am aware that various plans have been heretofore devised for heating cars or like structures, and that an air-chamber beneath the iloor of the car, through which the products of combustion from a lamp or other heater are passed, is not new7 and I do not broadly claim such a structure.

I claim as my invention A heating-chamber consisting of a temporary perforated floor laid upon supports B, placed on and combined with the permanent or lower floor and arranged in broken or interrupted lines to allow circulation of air, and heating-pipes D, running through this airro chamber between the upper and lower floors, substantially as described.
