Letters Patent No. 80,505, dated July 28, 1868.

BAILRDAD-GAE HEATER'.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN RICE, of l loomington in the county of Monroe, and State of Indiana, have invented a newr and useful Car-Heater; and I do hereby declare that the following is a full and` exact description of the same, reference being had to the accompanying drawings, and to the ietters of reference marked thereon.

This invention relates to `certain improvements in heatingapparatus for' railroad-cars, and consists princivpally in the construction and arrangement oi' the heater, as will be fnllydescribed hereinafter.

Figure 1, sheet 1, represents a side elevation ci' one form of my improved beater.

Figure 2a plan view of thesame.

'Figure 3, a sectional view of the flexible joint.

Figure 4, an elevation of the pipe-coupling, unccnpled.

Figure 5, sheet 2, represents a side eleva-tion -oi' another form or my heater,and

Figure 6 a plan view ol` tbesame.

In the drawings, sheet 2, A represents an iron box or chamber, which is securely attached beneathl the car, above the trucks. This box should be made sufficiently strong to prevent the trucks from forcing themselves up through the floor of the carin case of accidenti.

B represents the fire-box proper, which is attached below box A, at itscentre, as shown. This re-box is constructed with double walls and doors, for the purpose of shutting in the heat, and preventing the Ere-box from beingcoolcd by its rapid motion. It is also provided with suitable openings for draught upon each side,

" which have, of course, regulating-dempers, which latter may be operated from the car by any proper leverarrangomcnt. The iirc-box is divided into two parts, being separated by the chamber I, in Whichvlatter water maybe placed for the purpose of giving the heated air proper moisture. 'This chamber is covered with. an iron plate, which separates it suitably from thc other partsof the heating-apparatus. Openings, however', should be left, topermit the steam to rise and pass into the other parts. l

Opening into it, above the plate, upon either side, are the air-tubes D D, which extend in either direction, and communicate with the hotair chambers E E, one being located at each end of the our.

C C represent chambers communicating withthe chambers of the iire-bcx below. These are also covered in with iron plates, to shut-'oli` communication with other parts of the apparatus. Gpening intotnese also are the smoke-tubes F F, encirclingV the air-tubes D D, which former communicate with the smoke-chambers G G. It will also be observed that the air-tubes pass across these chambers, and thus-eccixfe heat directlyfrom the re below. Being also surrounded bythe tubes which convoy away/,the smoke and products of combustion, they retain the original heat, and constantly receive frcshsupplies from this source.

H H represent passages out through the smoke-tubes into the air-tubes, for` the purpose of tappingthe latter, and obtaining a supply of heated ai" at'any desired point.' i

I represents an iron plate covering the entire heating-apparatus.

z' represents the-smokespipe holes communicating with the chamber below.

i12" represent the cold-air entrances, which opcn'into chambers B below.

il 1? represent registers over the hot-air chambers, and 1,'3 t, registers over the openings H H.

It will be observed that, by the general arrangement before described, two large chambers are formed, JJ, around the smoke-tubes F F. In these also the air must necessarily become very much heated. This may be utilized by simply having a register open into it. The register t, placed over passages II Il, may be set a little distance above the tubes, which arrangement will allow the heat from chambers J J to pass out with the heat from the air-tubes.

In street-railway cars it may be desirable to make and tend.the lire within the car, in which case suitable doors should be made in the exterior plate, I, and interior plate over the fire-chambers.

The operation of my invention is es follows:

The tire is built in the tire-box B, either from above or below, as the case may be, and water is placed in chamber B. Cold air is admitted 'through the entrances i151, which open into the chamber B below. Upon entering thisl chamber', the cold air unites with the steam rising from the water below, thus receiving proper moisture, and passes into tubes D D, upon either side.

The first part of these tubes passes through the fire-box, and is highly heated thereby, which heat, being communicated to the air, is retained by it in its continued passage through the tube, the air being still further heated bythe hotgas and smoke in pipes F, which surround pipesD. These tubes may be extended the entire length of the car, it` desired.

By this arrangement the air is heated to a very high temperature by the time it lreaches the chambers E E. From there it is drawn ofi` by means of registers. Passages may becut through the smoke-pipes, andthe air-pipes tapped at any desired point, so that, if considered necessary, a register may be placed at every seat. The smoke and products of combustion arising from the tire-box, pass through the smoke-tubes, as described, into smokechambers G G, and are discharged finally through the smoke-pipe il.

The air-pipes may be extended with the smoke-pipes, if desired, and be carried with them up the sides of the car, in which case they may be tapped at both top and bottom, if desired'. Suitable openings in the outer box may be made, for the purpose of cleaning the tubes, when necessary. If desired., an additional pipe may be placed about the snmke-pipe, to insure a more perfect retaining of the heat. This, however, is not deemed necessary ordinarily. The air and smoke-tubes will necessarily expand more or less under the influence of the heat, and it is therefore proposed to make the partitions free at one end, i'n order that they may slide forward when the tubes expand, and backward when they contract.

In sheet No. l is shown a modiiication of my invention, and also the manner of conducting the heat from car to car.

In the drawings, I( represents an iron box, which may be securely attached beneath the floor of a baggagecar, or other suitable place.

K represents the re-box proper, which may be fired from above or'bclow, as desired.

L represents the air-tubes, which may open into a chamber provided with suitable outward openings, or they may communicate with the open air. These tubes pass directly through the tire-box, and also through the smokepipes, as previously described.

L1 represents the hot-air chambers, with conductors L2.

M represents the smoke-tubes, M1 the smoke-chamber, and M2 the stroke-pipes.

N N11 N2 representithe pipes which conduct the heat from car to car.- N3 represents the flexible joint, and N4 the coupling. The Ijoint is composed of the socket n and ball nl, the latter of which is provided with the groove u2, in which packing is inserted.

The pipe is smaller in size'than pipe N. This allows the joint to more freely to some extent, without v permitting the escape of the heated air.

The coupling consists of the pipe l, which is provided with the grooved and packed head or, which fits snugly into pipe l 2, the latter being provided with the enlarged opening, as shown, for the purpose of permitting the connection to be easily made. These different pipes are of sulhcient length' to permit .the pipe Nl to play forward and back in the pipe In without danger of disconnecting.

'lhe disconnection is easily made when the cars uncouplc, as the pipe N1 simply draws'out of the pipe N2. It deemed necessary, these pipes may be also made double, for the purpose of more perfect-ly retaining the heat.

The apparatus herein described may be used in summer as a ventilator, for which purpose it is exceedingly well adapted. i i

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'ihe heating-apparatus A B, constructed and arranged as described, that is, having the chamber B, air-tubes D in smoke-tubes F, chambers C C, E E, G G, and registers and discharge-pipcs, asshown, the whole being attached to and combined with a railroad-ear, and operating substantially in the manner described, and for the purpose set forth.

vThis specification signed and witnessed, this sixteenth day of May, 1868'.
