mas-veneer IN COUPLINGS FOR RAILROAD-TRAIN HEATERS i- The Schedule referred to in these Letters Patent and making part of the same.

To. all whom. it may concern Be it known that I, J 01m R. GUY, of Springfield, inthe county of Clark, and State of Ohio, have injvented a new-and useful Improvement in Apparatus for Heating Railroad-Cars; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure 1 is a perspective view of the furnace; Figure 2 is avertical section of the same; and Figure 3 is a side elevation, partly in section,- of the pipe for connecting the cars. The same letters are employed to designate the same parts in the difl'erent figures. In the annexed drawings, A is the exterior casing, within whichis a' furnace, B, of ordinary'construction, for wood or coal. The'diaught from the furnace passes through the pipe G.

' Disjhe hot-air chamber between the furnace and In this chamber is placed a fan, E, or other equivalent machine, for forcing the air through the pipe E from the hot-air chamber into the other cars in the train. This furnace isintended to be placed in the baggage-car, and the heated air is driven therefrom through pipes connected through the train, with registers in each car for regulating the admission of the heated air.

The fan is driven by a belt, F, passing over the pulley E and over another pulley placed on an axle of the car.

In order that the pipes may be connected from car to car, it is necessary that a coupling-pipe shall be used, which will permit the usual longitudinal vertical and lateral motion of the cars, and at the same time one which may be easily attached or detached. This I accomplish by the coupling shown in fig. 3, in which G is the pipe, permanently attached to the car. On the ends of this pipe I place sockets, H, the mouths of which are made flaring, as shown in the sectional part of fig. 3.

I is the coupling-pipe, on each end of which is a ball fitting accurately into the socket H. The socket being made of iron, this ball should be made of some softer metal, such as copper. An elastic packing may be used on the ball, as indicated inthe section, if preferred. 1 do not, however, regard this as essential. and-socket joint will accommodate every movement of the cars. The length of the sockets will permit the necessary longitudinal play, and as the ball will draw out of the socket when the cars are disconnected, and may be guided into it on coupling the cars, it will be seen that it presents no incom'enience in coupling or uncoupling the cars. This tubular coupling maybe used for heating the cars with either hot air or steam, or for trai'ismitting gas for illuminatingthe carsj Two of these furnaces may be used, connected either with separate of pipes, or, by a branch-pipe, with one set, to be employed alternately as'the car is runuing in opposite directions.

The furnace-door should be locked, and wire gauze or peribrated plates attached .to the draught exit to prevent the escape of coals in case of the overturning of the car.

The fan may be used to force cold air through the cars for ventilation in warm weather.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

In combinatioirwith the permanent pipes G and elongated, open sockets H, constructed with flaring months, the tubular coupling formed by a single rigid pipe, I, terminating with balls I, fitting said sockets,

This ball-
