ORSEMUS G. DAVIS, OF LUDINGTON, MICHIGAN.
PRESERVING. AND FREIGHT CAR.
SPECIFICATION forming part of Letters Patent No. 236,789, dated January 18, 1881.
Application filed March 3,1880. (ModeL) To all whom it may concern:
Be itknown thatI, ORsEMUs G. DAVIS, of the city of Ludington, in the county of Mason and State of Michigan, have invented certain new and useful Improvements in Preserving-Oars and Freight-Oars; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure l of the drawings is a representation of a side elevation of my car, partly broken away to show my improvements. Fig. 2 is a view of the stove and pipe, and Fig. 3 is a transverse sectional view of the car;
The nature of my invention relates to a carbody for preserving articles during transportation; and my improvement relates, essentially, to means for maintaining the air within the preserving-room of the car at a required temperature, as set forth in the following description, and pointed out in the claim.
In the drawings, Adesignates the car-body, and B its roof, which is provided with the usual center strip, 0, and side guards, D. Upon the platform are arranged the ordinary guards E and any suitable or well-known braking devices.
The car-body is divided into two compartments, one of which, G, is used as the stoveroom, and the remaining compartment, H, as the preserving-room. The walls of the preserving-room are disposed as' follows, so as to constitute a series of walls with spaces between them, to wit: A wall, I, is constructed Within the car-body so as to leewe a space, I, between the said wall I and the wall I of the car-body. The opposing faces of the walls I 1 are lined with zinc and the space between them filled with charcoal. The wall I is lined inside with heavy stiff paper, and an air-space, K, left between this wall and the next inner wall, L, which is also lined inside with like paper. An air-space, M, is also left between the wall L and the last inner wall, N, which last-named wall is lined with zinc upon its inner face. At the lower corners of the preserving-compartment are gutters or water-ways P, to collect any water therein, and this may be carried by short pipes into the stove-room. The spaces between the aforesaid walls have ribbing R, and apertures R are made through the paper and paper-lined walls, so that the spaces between them will communicate. At the corners of said walls are angle-straps, which strengthen the structure.
It may here be observed that no bolts pass entirely through the walls, since the metal thereof would communicate cold to the preserving-chamber.
The doors S, which open into the preserving-chamber, are formed with spaces similar to the above-described walls, and are formed with beveled edges adapted to fit closely into the sills.
T designates the stove-pipe, from which a heating-pipe, U, extends into the preservingroom, and thence back again to the stove-pipe. In the two branches of the pipe U, between the stove-pipe and the partition V, are valves V, both valves being controlled by a single stem, V In the stove-pipe, between the arms of the pipe, is arranged a valve, U, the method of heating the preserving-room being as follows:
The valve U being closed and the valves V opened, heat will pass into the pipe U, and thence back into the stove-pipe and up through the flue, which extends up through the roof. When the valves V are closed, however, and the valve in the stove-pipe opened, heat will be shut off from the pipe which leads into the preserving-room, and the heat will then pass directly along the stove-pipe and up through the flue.
To determine the temperature of the preserving-room I provide a thermometer, W, at one end of the said room, which is visible through an opening, W, having glass windows.
In summer ice may be used in the stoveroom in lieu of a stove, and any suitable means employed for conducting the cold air into the preserving-room. Suitable means will in such case also be provided for collecting such drippings as may occur in the stove-room. The
car-top will be provided with suitable pipes, preserving-room and. returning therefrom to W, for purposes of ventilation. the pipe T, substantially as and for the pur- What I claim isposes set forth.
