TO WHOM IT MAI CONCERN:

Be it known that I, SAMUEL W. FRANCIS, oi' Newport, in the-county of Newport, and State of Rhode Island, have invented certain new and useful Improvements in Heating and Ventilating Railroad-(lars;v and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accom panying drawings,

'The object of my invention is to provide a simple'and economical means, whereby railroad-cars may be either ventilated, or both heated and ventilated by means of air taken from the front of the locomotive; the heat, when required, being derived from the locomotive-boiler or fire-chamber. To this end the invention may be stated to consist in the combination, with the locomotive, of the air-tube or conduit communicating with pipes opening into the cars, and a removable heat-confining jacket surrounding the said conduit, under the arrange. ment hereinafter described, "so that the said conduit and pipes may constitute either a ventilating or aheating; and vcntilating apparatus, as required; I I v To enable those skillbd in the art to understand and use my invention Iwill now proceed to describe the manncr'iri which the same is or may be carried into Acfl'ect, by reference to the accompanying drawings, 'in which- Y Figure 1 is a longitudinal vertical'section through a locomotive and passenger-car united, to which my improvements have been applied.

' Figure 2 is a top or plan viewof the same.

Arepr'esents a locomotive, B its tender, and G a passenger-car. Applied to the locomotive there is a tube or conduit, D, which opens in front of the locomotive, its end being surrounded by a fiinnel-shaped mouth, a, and covered by a hood, 6. The object of the funnel is to direct the air with more certainty to the conduit, while the hood prevents rain or snow from beating into the open end.

The air-conduit passes down under the boiler of the locomotive, and when it reaches the fire-chamber, divides into two branches, one passing on each side of the fire chamber, as seen in fig. 2'. The branches extend across to the tender, and are theremounted so as to form one tube, which is carried out through the back of the tender, and fits in the end of a pipe, E, placed on the passenger-car G. I A packing, 0, between the two pipes, makes 'a tight joint, at the same time that the tube D is free to slide in the end of the pipe E, so as to conform to the movements of the car and'tender. I

Thepipe E enters the body of the car, and is then divided into two branches, one passing under each row. of seats 12. A number of openings, f, closed by registers is formed in each branch E, and by opening or 0105'- ing the registers, the hot air is admitted into or excluded from the car. v

The operation is as follows: When the train is in motion, air enters the conduit through its open end in front of the locomotive, and thus a supply of air, free from dust and other impurities, is always obtained.

The air passes through the conduit, and is almost immediately heated by the heat communicated from the boiler and firc-chamber-along which the conduit extends. I i i That part of the latter which is contiguous to the boiler and fire chamber is completely covered by a'jacket, F, within which the heat radiated from the boiler and fire-chamber is confined, so as to increase greatly the action of the heat upon the conduit and air passing through it; The air, which by this means, becomes highly heated, passes along through the tube into the pipe E, and is there discharged into the body ofthe car 0 "through the registers; and by opening orclosing one or more of the latter, the car may always be kept at the proper temperature.

In summer, when no heated air is required, the apparatus may be used as a ventilator by removing the 'jacket F, which is held in position by bolts and nuts, or other suitable means.

The conduit, in such case, will beexposedto the outside air, and the heat-from the boiler will be dissipated to a great extent, so that the air passing through the conduit will remaincool, and will pass in this state tothe cars, which it enters through the requisite valves, as before.

By this simple arrangement, therefore, I am enabled to use the apparatus either as a ventilator or a combined heater and ventilator. 7

Having now described my invention, and the manner in which the same is or may be carried into effect, what I claim, anddesire to secure by Letters Patent, is'- v The combination, with the locomotive, of the air-tube or conduit communicating with pipes opening into the cars, and a removable heat-confiningjaeket surrounding the said conduit, under the arrangement herein shown and described, so that the said conduit and pipes may constitute either a ventilating or a heating and ventilatingapparatus, as herein shown and described.

In testimony whereof, I have signed my name to this specification before two subscribing witnesses.

' 'SAML W. FRANCIS.
