To describe more in detail the several parts of the motor: 1

The boiler C illustrated is'ofthe multi-tubular'type and consists of acylindric shell,1O,

having a flat bottom, 0, a curved or, dome shaped -top,.c, and a pluralityof tubes, m

connected with and opening through thesaid O, communicating at its top with an exit-pipe 'orsmoke-staclz, O and between the boilerbottom and top plates. The boiler constructed h in the manner described is surrounded at: its a top and sides by an exterior shell or casing,

shell and the said exterior shell,O ,is placed a bottomless shell, O,which extends about the top and sides of the boiler proper and divides the space inclosed between the exterior shell' and the boiler into two parts or chambers. The exterior casing, C, is extended at its lower edge below the bottom plate, 0, of the boiler, and the side walls of the boiler-shell (Y are simibottom plate, a, and the flame and heated products of combustion pass upwardly through the tubes 0, then downwardly in the space between the boiler-shell and the shell 0, around the bottom of said shell 0*, and then upwardly adjacent to the exterior casing, 0 and make their escape through the smoke-pipe. The boiler illustrated is provided with the usual safety-valve, O pressure-gage O, and watergage 0 (1 is a steam-pipe leading fromthe topof said boiler to the engine-cylinders F F,

said steampipe, as more clearly shown -in Figs. 1 and 2, being extended from the top of the boiler downwardly through the floor of the car-platform, and then horizontally to the point opposite the said cylinders, where it is carried across the car, and is connected with thesteam-chestsf f of the cylinders by means of suitable branch pipes. A branch, 0", of the pipe 0 is connected with the latter at a point adjacent to the top of the boiler, and extends downwardly through the car-platform and beneath the bottom of the car, and is connected with the exhaust-pipe from the cylinders, as

will hereinafter fully appear.

The oilburner D, herein shown as applied to heat the boiler G, is constructed as follows:

. The burner consists, in its essential features,

of a porous or perforated bed or filling, J, made of fire-brick, asbestus, or other porous substance, but which may be made of sand or grave] or of cast-iron vertically perforated, as shown, and a shallow receptacle or trough, D", which is adapted to receive and hold the said porous bed or filling. The said trough D is, supplied with oil or other liquid hydrocarbon by means of a supply-pipe, K, the oil delivered to the trough rising through the porous bed and being burned at the top of the said bed, in the manner set forth in the said prior application hereinbefore referred to.

In the particular construction of the parts herein illustrated the porous bed J is of annular form and the trough D is of similar shape. As a convenient construction in the parts, a casing constructed to surround and support the parts of the burner is formed by a cylindrie side wall, d, herein shown as forming a continuation of the shell of the boiler, and a'flat bottom plate, D. Upon this plate are formed or attached two concentric annular flanges or rings, D D, forming,with the plate, the annular trough D. The said plate D is preferably provided with a series of studs or prominences, d, upon which the porous bed rests, thereby forming a space or opening beneath the said bed. With this space the oilsupply pipe K, which in this case is made of circular form and located beneath the plate D is connected by means of short vertical branches It. (More clearly shown in Fig. 5.) The supply-pipe K is connected by a branch, K, with an oil-tank, K, which is preferably located beneath the seat at one end of the car, asindicated in dotted lines in Figs. 2 and 3, said supply pipe being preferably provided with aregulating-valve,K-such, forinstance, as is shown in a prior application, Serial No. 210,047, filed in the United States Patent Office August 5, 1886. The ringD, whichforms the outer wall of the trough D in the particular construction illustrated, extends considerably above the top of the porous bed, and-is curved outwardly and attached at its upper margin to the wall d of the casing. The ring D, forming the inner wall of the trough,-terminates slightly above the level oft-he top of the porous bed, and the upper edge of said wall, in connection with the lower edge of a concave or flanged casting, D sustained centrally vwithin the burner, forms a narrow annular passage, j, by which air to support combustion is admitted to the top of the porous bed. The casting D may be conveniently sustained by legs d, resting upon the plate D in the manner shown. Air isadmitted to the central space of the burner through openings d formed for the purpose in the middle of the plate D, the air entering the said space passing therefrom through the annular passagej to the space over the porous bed, where combustion takes place. For controlling the openings d d a suitable valve is provided, herein shown as consisting ofa rotating plate, L.pivoted at the center of the plate B and provided with apertures d. For operating the valve L the latter is preferably attached to a vertical shaft, L, mounted to rotate in a hub, d, upon the plate D", to the lower end ofwhich shaft is attacheda spur-wheel, U, which is engaged by another spur-wheel, L mounted upon a shaft, L, which extends upwardly through the floor of the car-platform, and is provided with a hand-wheel, l, by which the shaft may be turned and the valve moved. An additional .means for controlling the burner is herein shown, consisting of a valve in the smoke-pipe 0", said valve being actuated bya lever, 0 provided with a weight, 0, holding the valve normally open.

(1 is an annular flange formed or attached upon the upper surface of the plate D between the frame D and the air-inlet openings (P, for the purpose of confining any'oil which may overflow from the trough D". Any. oil overflowingin the mannerdescribed remains upon the plate d until vaporized by the heat of-the burner.

D6 is a door applied to the sidewall, a, of

the burner-casing, and d is an opening placed g in the ring D opposite the said door and adjacent to the top of the'porous bed, saiddo'o'r and openingd being for the purpose of allowing access to said bed for the purp ose'of lighting the oil in starting the fire. 7

I prefer to construct the boiler and burner made as above described of such size and shape and to so locate them upon the car.-

frame that the top of the boiler will not ex-' tend materially higher than does the hand rail (indicated at A) commonly present upon car-platforms."- This construction obviously enablesthe driver or operator'to command an unobstructed view of the trackand roadway ahead when standing upon-'the-platform. It

is to be understood, however, that the proportions orsize of the generating apparatus may be variedin practice from theseshown -as,

for instance, the top ofthe generating apparatus; located in the manner shown may beconsiderablyhigherthan the hand-rail A without 1 obstructing the View of aperson standing upon v tus.

ond-smaller tank or chamber,E, these tanks in the particular construction illustrated being the platform. T

The feed-watertank E, which is located at the end of the car opposite that at which the boiler'O is placed,consists of a cylindric vessel of generally thesame shape and size as the exterior-casing of Y the generating appara- Beneath the said; tank is located a secboiler, which is introduced therein through the open pipe or tube E or otherwise, and which, while in-said tank, is free from steam or other pressure. a

E is a pipe which is connected at one "end with the top of the chamber E, and is pro- :vided at its opposite discharge endfwith an enlarged and perforated head, 6, located in'the lower part of the upper chamber, E. The

part of the pipe E between-its ends. is extended'to a point'above the usual water-level of the tank E, so as to prevent the passage of water by gravity from the said tank to the chamber E. Said pipe E is preferablyfmade of considerable length and arranged spirally within the tank E.

E is a pipe extending from the lower part.

of the'chamber E upwardly to a point above the water-line of the tankE and opening into the lower part of said tank.

M. is the exhaust-pipe from'theengine-cylv inders, said pipe being connected by branches m withthe cylinders, and being extended beneath the car-floor to the chamber E", within the upper part of which itdischarges, as'clearly shown inFig. 2. The-water within thetank 'E'fills the greater part of the said tank and 1 covers thecoiled portion of the pipe Eflandl p a the exhaust-pipe is forced "by thep ressure of: j ,the' exhaust steam through the said "tube E,

the steam enteringthe said'cham-ber E'through and passes from the perforated headisa'thereof .into the water WhlClllS within the said tank.

In-itspassage through the icoiled part of the pipe Ethe pipe is heated and aportion'of' the heat of the steam is thus transmittedto the water-,.-iwhile at the same timeapartof the steam i-s coudensedwithin thepipeand returns to the chamber E. Theexit end of thesaid tube E is preferably provided with the perforatedheade, in orderlthat the steam may be divided into fine jets as it enters thewater;

thereby' facilitating its 'condensation, "Theychamber E is employed mainly for 'thefpiu'n pose of equalizing thep re ssu're of the-steam, which obviously comes in puffsthroughthe exhaust-pipe, and thereby'prevents-the noise which would be caused by the passage of the steam'directl y from the exhaust-pipe into'the water; A considerable'part of the steaiii delivered into thechamber'E willobviously be conrff densed'therein,and the water of condensation.

from the 'coilE" retur'nsto the said chamber,

so that in'the operation of the device water will accumulate in considerablequantities in the bottom of said chamber E.

The 'pi e rr is for; the purpose of causingthe continualdis charge from the said chamber ofthe water which-thus accumulates therein, and for this .purposethe openlowerend of the said pipe E is located at apoint close tojthe bottom of said chamber E, so that said lowerend of the pipe will always bebeneath the surface of the water containedinthe chamber. It is entirely obvious that when the parts are thus c'onstrncted the pressure of thefexh'aust'steam within the chamber E "uponthe top of the" water .therein'vcontaine'd will force the said water upwardly through the pipe E5, and

thereby cause its discharge into. the chamber Y E. The discharge end of the pipe E maybe located eitherin the upper or lower part of the tanklEyi'ts location at thelower part "of? the tank being preferred, in orderto'insure i against the free escape of steam fromith'ei' chamberE m the open 'air inc'ase the water is low inthe tank and-thewater is forcedout of the chaniber Efaster than it accumulates; so as to allow steam to follow'the' water through the saidpipe When the pipe E isarranged rzs I asshownin the drawings, it will preferably be 7 provided with a"check-valve, c, tofrestrain any-backward flow ofwater. therein, and to,

thereby prevent'the water in the tank being "siphoned into the-chamber Efwhen the, steam;

pressure is removed from the said chamber.-" i' The steam-generatingdevice, 'consi'stingflof the boiler and the burner connected therewith in the mannerdescribed and the water'tank E, may be sustainrd upon the frames of the carplatformsin any suitable way. One desirable construction for this purpose is herein shown in Figs. 2 and 3, in which the parts mentionedare each supported by a circular casting or.

ring, A, which is provided with an inwardlyextending flange, a, adapted to engage the oil'- set or shoulder at the lower part of the boilercasing C in one case and tofit beneath the bottom of the chamber E in the other case. The said ring A is desirably supported upon the car-frame by means of arms a a, cast integral therewith and extending rearwardly along the inner side of the platform-support a, to which they are secured by bolts a At their sides and adjacent to the platform the rings A A are desirably provided with horizontal flanges at, extending over and resting upon the transverse frame-piece a of the carplatform. In the device shown the castings A are formed to provide sockets a. a for spring-buffers A and are constructed to support trackclearers A A.

N is a pipe by which water is carried from.

the tank E to a feed-pump, N, from which it is forced through a feed-pipe, N to the boiler. The said pipe N is provided with a vertical part, n, within the chamber tank E, said part n terminating near the bottom of the said tank. The feed-pump N is made in the ordinary manner and is actuated from an eccentriqh, upon the shaft H of the driving-gear.

N is a rod connected with a valve controling an air-inlet opening to the feed-pump, whereby air may be admitted to the said pump at the times when the pumping of the water is not required in a familiar manner. The said rod N extends from the feed-pump to a point beneath the platform A, where it is connected with ahand-lever, N, extending upwardly through the said platform in position convenient for its manipulation by the driver.

The steam pipe or tube 0, for allowing the escape of steam from the boiler, is connected with the exhaust pipe N, as shown in Fig. 3, so that steam allowed to escape from the boiler will pass through the said exhaust-pipe into the tank E, where it is wholly or partially condensed, and thus disposed of without noise. Inasmuch as the tank E is in free communication with the open air, any uncondensed steam passing from the water will make its exit quietly and without noise from the top of the pipe E either when the steam comes directly from the boiler or when it passes from the exhaustports of the cylinder.

Inasmuch as the engine-cylinders F F and other operative parts of the driving-gear are mounted upon the frame I, which is supported upon the wheel'axle in the manner before described. aud the ear-body is supported upon said axles through the medium of springs in the manner common heretofore, itis obviously necessary to provide .for a movement of the parts of the several steam, feed-water, and ex haust pipes, which are attached to the carbody with relation to the portions of said pipes immediately connected with the driving-gear and supported upon the frame I. For this purpose I have herein shown each of the said several pipes as provided at points between the ends of the car and the said driving-gear .with flexible sections 0, formed by thick rubber tubes 0, connected at their ends with the.

pipes and re-enforced by exterior spiral wrappings, 0, of wire.

The slide valves of the steam cylinders shown are provided with a common form of link-motion reversing-gear, P, the reversinggear belonging to both cylinders being controlled by a single transverse rock-shaft, P, which is connected with the links by means of arms p and connecting-bars p. Said shaft is provided with a rigid arm, p, to which is connected an actuating-rod, P, which extends to a reversing-lever, P, mounted upon the carplatform A. A single counterbalance-weight, p for both reversing-gears is herein shown as applied to an arm, 1), fixed upon the shaft P.

To provide means for changing the speed at which the car is driven, and at the same time to increase or decrease the driving-power, I provide, for connecting the transverse driving-shaft H of the driving-gear with the axle B of one of the car-wheels, two or more sets of gear-wheels, either of which may be thrown into action, as desired. For-this purpose, in the device shown, the wheel axle B is provided with aspur-wheel, Q, adapted to intermesh with aspur-wheel, H, upon the said shaft H. The spur-wheelH is considerably smaller than the spur-wheel H,and on the other hand thewheel Q is smaller than the wheel Q, so that when the wheels Q and H are in position to intermesh with each other the car may be driven at the highest speed and with the least power, and when the wheels Q and H are in engagement the car will be moved more slowly, but with increased power. To provide a convenient means for shifting the gear-wheels to cause the engagement of one or the other pair thereof, the wheels Q and Q are desirably attached to a sleeve, Q, splined to the wheelaxle B, so that it may slide freely longitudinally thereon, and the said wheels Q and Q are placed at a less distance apart than the wheels H and H, sothat when the wheel Q is engaged with the wheel H the wheel H will be free from the wheel H. When the parts are thus constructed, it is entirely obvious that the shifting of the sleeve Q a short distance in either direction will bring the wheel in either position for engagement with either one of the wheels upon the shaft H, as desired. For shifting the said wheels 'Q and Q',I have herein shown the sleeve Q as p'rovidedwith an annular groove, q,which is engaged by a ring, q, to which is connected one arm of a bell-crank lever, Q supported upon a vertical pivot, q",

' and connected with an operating-rod,Q,'vvliioh "surroundthe same by acasing', R, attached to;

This casing lzpreferably provide .witha re-; movable top',-R,by, means of whicheaccess. may vbe had to the driving-gear for the purpose of oiling the same or for-making repairs; 1

I The middle part of the car-floor is desirabl ,cut away over the casing R, and the opening: thus made is covered by .a*grating,.YR sn'stainedslightly above thetop of, the casing, so

body in the yielding of .the' springs, said top? being adapted forconvenient removal toal or receptacle, E, communicating-at the topv 85 low access to the interiorof saidc'asing. The supporting-frame I may beconstructed;

in any convenient or 'preferred, manner; but,-.

. as herein shown, itconsists'of two longitudi II nal bars, I I, to the ends of'which the beari ngs't' 't' are attached, said bars being extended; 2 beneath theseveral-parts of. the, driving-gear' and upturned at their ends for attachment to.

the said bearings i t, as clearly shown in Figs.

3 and3. The said bars I I are rigidly con nected by suitable cross-bars, 1, upon which the cylinders F andfbearings for the severalshafts are attached orsustained.

One important feature of novelty in the driving-gear is embodied in the" construction wherein motion is communicated from the piston-rod of each of the engine-cylinders to the driving-shaft G by means of a cross-head, F, and two connecting-rods, F F, extending from the cross-head toward and past thecylinder at. I I

or receptacle, E, communicatmg at its topwith x05 the open 'air, and a chamber, E, connected I bothsides of the latter. By this construction a desired length of connecting-rod may be pro-- vided, while at the same time theentire driv-' ing gear may beeasily placed within the space-- between the caraxles.

By the employment in a motor for street cars of a steam-generator at one end of the car and a tank for feed-water at theopposite end 'of the car, in the manner shown, these parts are so placed as togoccupy none of the space in the car-body, so that the space for passen-' gers is not curtailed, while at the same (time the weight of the boiler is counterbalanced by the feed-water tank, and an objectionable pre ponderance of weight at either end of the car is thereby avoided.
