IMPROVEMENT INEEA-riucrA'NDl vx-:NTuin-lflNoRuLRoAlxcARsl d Specification lforming ,part of Letters Patent No. 74,386, datedFebruary l1, 1868.

To all whom 'it may concern.'

`Be it known that I, SAMUELI LLOYD, of the city 'of- 'Washingtom have invented a new and useful VMethod of District of Columbia,

Heating and Ventilating Railroad-Cars; and thefollovving is a lfull, clear, and exact de- 'v scription thereof, reference be'ng -had -to the accompanying drawing, and to the letters of reference marked thereon.

Figure 1 is a vertical section through alocof motive and heating-car. Fig. 2 is a sectional view of the coupling-pipe for conveying heat fromcartocar.. .The object of my invention is to heat and ventilato atrainof railroad-cars by means of hot and cold air conveyed into the cars from.` apparatus on locomotive, and in a heating and ventilatingv car, so as to obviate 'the' use of stoves in-each car, thereby giving greatersef curity to life and economy of room and fuel.

l To enable others skilled in the art to makev and use my invention, I will describe it more fully, reference being had to the accompanyin g drawing, and to the'letters marked` thereon.

Letter A, Fig. l., is a locomotive, having a lhood or opening, a, underneath the cowcatcher, for the purpose of gatheringthe air, which is conveyed by the pipe bV through the flue-chamber, kand s pirally around the interior of the smoke-stack of the locomotive, thereby heating the air in the pipe. The pipe b, leaving the smoke-stack at its base, andy passing along the Voutside ofthe boiler, beneath the locomotive, is connected with the horizontal pipe c, which connects by the iiexible coupling l) with another. horizontal pipe,.` d, whichis coupled with and conveys air to the passenger-cars, the hood a supplying a current of pure air, which it is'unnecessaryto pass through water, and may be either hot or cold, the change-being effected by means of the agitator p, and exhausting into the receiver process.

Letters e e is a jacket inclosing, as far as practicable, the 'hot-'air chamberof the caloricengine. The cold air is received into the jacket by'means of a hood, r, and pipe y,'the supply being regulated by the valve u. It` isn then passed around the hot-air chamber of the caloric-engine by means of a spiralv line, the sections'ot' Vwhich are marked f f ff, and by the pipe j j and valve m, forced by the blower H through- 'the pipe o into the receiver Gr, or by means of the valve l and pipe n, connecting with thevpipe o, passed directly into the receiver by means of .the draft created by the movement of the train. A

Letter F.- is a'furnace Imany as necessary being used-jacketed and 'regulated by valves, as described in the caloric-engine, and containing a spiral coil of pipe, g g, in the lire-chamber, through which a portion of v'the air passes, thereby giving a. greater heating-surface, the heated air from being conveyed by the pipe h the furnace The connection with the into. the pipe j at k.

-furnace may be closed or regulated by means of the valve Letter s is a hood for supplying the cars' with cool air, and is connected `with the blower H by means of the pipe p, and closed by the valve o when hot air 1s used; but the air cali.

be takendirectly intothe receiver by `1neans of a connection between the pipesvt andl'o and the draft occasioned by the movement V,of the train. A

. Letter G is a receiver, partly iilled `with water, through which the air passes by means whose mouth opens under the of the -pipe o, water. y

Letter p is an the purified air from the receiver into the pas\ G by means ofthe pipe o, after 'first passing 4the exhaust hot air through a deodorizing for heating air-as agitator run bymeans of the caloric-engine, or a pulley attached to the axleV i of the car, andv working 'in the water directly over the mouth of the pipe o, thereby driving .the air through the. waiter, so that it will be y thoroughly iiltered and freed of dust.

fw w which mayl be in front of the supply-pipe q as the car runs'.`

The tir, either het er een, is distributedthrough the cars by means of a pipe or pipes, cased or not with a non-conductor of heat, running along the 'bottom of the cars, and

havin gone or more registers .openinglin each. car.

- The open end of the Vfixed conductingpipe of the last car can be closed with a screwcap, so that all the air will pass into the cars',

'each -car being provided with one or more' Ventilating-hoods on top' of each car, Awith valve-openin gs, Vso as to regulate the tempera;` ture and ventilation. i

Letters'd d, Fig. 2, are portions of thevxed;

'conducting-pipes, and aremade of any suitafl bie material, incased or not in a non-conductor of heat. --b b fare male 'screws' or couplings@ c' is a female screw-coupling attached to and Working freely around only one'end, a', of the hose or flexible connection D, so that the other end, 1c', may have a free llateral motion .in a stufin g-box, f so as to facilitatethe coupling o1" uncoupling of the cars, andallowfor the free lateral motion of the cars. Both ends of the fixed conducting-pipes d d are' provided witli male screws b' b and stuing-boxes f f', with a packing of rubber, 'g'I g', or other suitable material, making an air-tight connection sof that ythe flexible' connection can be coupled'to either end of the fixed conducting-pipes d d, so that it Will not be necessary to reverse the ends of the cars to make connection.'

Letter .a' is an extension of the connection into thel stating-box, uponv which thel connec- -tion is 'coupled,takin`g the strain'oii' of the screw-coupling, and supporting the flexible connection 'pipe D when the cars are unon the ground.

Letter h 'is a flat' steel spiral, iirlnly 'connected with the ends a and e', keeping'the ihose extended and in a proper shape, covered With a' layer of Holland duck, a layerof vulcanized rubber, the Wholerprotccted by a covering of stout leather, forming a dexible hose or /connectiom which takes the strain caused by the vibratory motion of the cars o 'from the ixed conducting-pipes d d, and allows for thefree turning of curves.
