REFRlGERATlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 236,712, dated January 18, 1881.

Application filed July 16, 1880. (N0 model.)

To all whom it may concern Be it known that I, JACOB LORENZ, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Refrigerating-Oars, of which the followingis a specitication.

In the accompanying drawings, Figure 1 is a side elevation and part section of the body of a car embodying the new improvements. Fig. 2 is a sectional plan, and Fig. 3 is a vertical transverse section of the same.

In the construction of these cars many features are involved which will be found fully described in Patent No. 145,066, issued to L0- renz and Bender, December 2, 1873, and in Patent No. 204,586, issued June 4, 1878, to the same parties. Both these patents relate to refrigerators, and should be consulted in connection with the improvement herein specified.

As shown, the car is constructed with three walls, B, D, and F. This triple wall or casing is complete, and applies to sides, ends, roof, and floor. The space C, between the two outer casings, is left hollow and forms an air-jacket. The space E, between the inner walls, is filled with mixed charcoal and ashes, or any other suitable non-conducting substances.

The doors M are constructed with an airjacket and a non-conductor, the same as the general walls. The doors open inward and close tightly against rabbets, as shown. The shifting of contents of car may block the doors and prevent their being opened. A small door, N, called the sub-door, is hung in one of the main doors. This door closes tightly, but opens outward. Ingress to the car may thus be had shouldthe main doors be found blocked.

The air-spaces of thefloor are not connected with the spaces in the side walls, 850. Openings P, Fig. 1, at each end of the car allow a free circulation of air in the floor-spaces. The openings P, and in fact all external orifices, should be gauzed or otherwise protected from sparks and dirt. Holes H at each end of the car allow air to circulate in main air-spaces. Metal tubes G, placed in the space between the inner casings, F and 1), permit air to leave the interior of the car at the top through openings I, and discharge into the air-jacket near The inner casing,

the floor through exits J.

F, is perforated, as at K, so as to expose the tube G to the condensing influenceof the cold interior of the car. The air, entering the tubes G at the top, condenses,descends, and exits at J into the air-jacket O. The orifices through out may be gauzed or otherwise protected, and may be provided with regulating-dampers. and ends of the car, as shown.

At the ends of the car, alongside the tubes G, are arranged the entry-tubes t, as shown in Figs. 3 and 2. These tubes admit air from the exterior of the car and discharge it into the car, near the floor, through openings 1. The tubes 15 operate, by condensation of air, the same as tubes G, and perforations K are provided for them also. The inlet-tubes t are only needed when the car contains substances likely to develop impure gases. In ordinary cases the inlet-tubes are omitted in construc: tion, or suppressed in use by the closure of dampers M inside the car. may be arranged at the sides of the car, if desired.

Across the floor of the car, say a couple of feet from each end, are fixed the ledges a. The spaces at the ends of the car within this ledge form the ice-pans, and should be lined with zinc or galvanized iron. For short trips the small quantity of ice needed is laid in these end pans. For long trips more ice is required, and it is desirable that the ice be placed in well up above the floor of the car. Provision is made for the high storage of a goodly quantity of ice, as will now be explained.

At each end of the car a slatted shelf, S, is hinged to the inner end wall of the car. These shelves have hinged legs U, and when the shelves are not in use they, with their legs U, fold neatly up against the end of the car, as shown at the right-hand end of Fig. 2. When the shelves are down and in use they are in position to hold ice, which may be stored clear to the ceiling of the car. The ice-pans T are directly under the shelves and catch all drip from the ice. Slatted gates or patitions R hinged to the sides of the car close against the edges of the icc-shelves and prevent the falling of ice. When the gates B are not in use they open neatly against the sides of the car.

The tubes G are arranged in the sides The inlet-tubes t The gates R are provided with hooks V, into which a downward projection on the front edge of the shelves engage. When the iceshelves are loaded the gates are closed, and a slight lifting of the shelves permits the hooks V to pass under the projections of the shelves, which, in dropping back, lock the gates shut. In Fig. 2 the left end shelf and its gates are in position for use, and the right-hand ones are folded out of the way.

Any proper kind of fastenings may he arranged on the shelves and gates, and the shelves may, if desired, be fixed immovably to the car. The gates may be fixed or arranged as a simple movable partition, or the shelves may be arranged as cribs to hold sufficient ice, and be supported a fair distance from the floor in any suitable manner.

A longitudinal trough, c, islocated beneath I the floor in the center of the car. The flooring of the car projecting over the sides of the trough, as shown in Fig. 3, leaves but a small portion of the trough uncovered. The resulting crack permits the trough to be cleaned, and forms the entry for the drainage of the floor. The inward projection of the floor prevents any mussy spilling of the contents of the trough when the car tips in rounding curves. The floor slopes to the trough, so as to drain well. Gutters b conduct water from the icepans T directly to the trough, and the sloping of the floor drains the body of the car. Trap-doors d at the ends and centerof the gutter give free access to the gutter at these points. c is the king-bolt of the car, and the gutters b are placed diagonal, as shown, to clear it.

At the center of the trough, under the car, is placed the outlet-trap O, which permits the outward flow of water but prevents the inward flow of air. Into the outlet of the trough is screwed the nipple 1). (Shown in Fig. 3.)

This nipple may be so adjusted that no water will leave the trough till it is nearly full. The intention is to allow the water to accumulate in the trough and be discharged at the end of a journey, and at the same time to guard against overflow. The trouglie is, in fact, a reservoir, and for short trips no outlet is needed, as the contents may be drawn 01f at the end of the trip.

I claim as my invention- 1. The combination, with a hinged car-door arranged to open inwardly and operate as usual, of a panel or sub-door arranged in the face of said door, and adapted to open outwardly, substantially as and for the purpose set forth.

2. In refrigerator-cars, the air-space O in the floor of the car, completely inclosed by airtight Walls, and provided at each end with opening P, communicating with the outer air, substantially as and for the purpose set forth.

3. The combination, with the metallic airtubes, of the inner lining of the car, provided with perforations to expose the air-tubes to the cool interior of the car, substantially as set forth.

4. The combination, with a car-body, icereceptacles, and drains, of a longitudinal central reservoir located beneath the fioor, and provided with an overflow-outlet and air-trap, substantially as set forth.

5. The combination, with a longitudinal reservoir located beneath the floor ot' the car, of the floor sloping from the car-walls to the reservoir, and projecting over the shores of said reservoir, substantially as set forth.

6. The ice-pans at the ends of the car, combined with drain-gutters and a central reservoir, substantially as set forth.

7. The ice-crib formed of a shelf and gate hinged to the Walls of the car, and adapted to fold against the walls of the car when not in use, substantially as set forth.

JACOB LORENZ.
