SPECIFICATION forming part of Letters Patent No. 712,829, dated November 4, 1902.

Application filed August 12, 1902. Serial No. 119,431. (No model.)

To all whom it may concern.-

Be it known that I, JOHN EDWARD MIL- LARD, a citizen of the United States, residing at Poughkeepsie, in. the county of Dutchess and State of New York, have invented new and useful Improvements in Motor-Vehicles, of which the following is a specification.

My invention relates to improvements in motor-vehicles; and it consists in a steam motor-vehiclein which the generator, engine, water-tank, and fuel-tank are mounted entirely on the running-gear in the peculiar and advantageous manner hereinafter described, and particularly pointed out in the claims appended.

In the accompanying drawings, Figure 1 is aplan view,with parts broken away,illustrating the generator, engine, water tank or tanks, and fuel-tank arranged on the running-gear of a motor-vehicle in accordance with my invention. Fig. 2 is a longitudinal vertical section takenin the plane indicated by the broken line 2 2 of Fig. 1 and illustrating the spring-supported body of the vehicle in position. Fig. 3 is a transverse section taken in the plane indicated by the broken line 3 3 of Fig. 1 looking in the direction indicated by arrow. Fig. 4 is a rear elevation illustrating the rear axle of the running-gear and the manner of mounting thebody thereon. Fig. 5 is a detail plan view of the frame forming part of my improvements, and Fig. 6 is a detail longitudinal vertical section taken in the plane indicated by the broken" line 6 6 of Fig. 5.

Similar letters of reference designate'corresponding partsin all of the several views of the drawings, referring to which- A is the front axle, and B the rear axle, of the running-gear of myimproved vehicle, and O is theframewhich is interposed between and supported by said axles and has for its general purpose to carry a steam-generator, an engine, a water tank or tanks, and a fueltauk, as willbe hereinafter fully described and claimed.

The front axle A, Fig. 3, is provided at its ends with bearings Ct for the bell-cranklevers b of a steering-gear, and at its middle it has an enlargement c, on which is supported by a rubber or other spring cl a bearing f, having a longitudinally-disposed aperture 9 for a purpose presently described. Said axle A is also provided with a truss-bar h, which is connected at its ends to the bearings a and supported at its middle by uprights 't', rising from the axle. On this truss-bar h, at the middle thereof, is a pillow-blockj, to which is connected the forward spring is for supporting the body D, presently described. The spring (1 between the bearing f and the enlargement c of the axle A has for its purpose to cushion the frame 0 and the machinery carried thereby, as will be presently made clear.

In addition to the beltcrank levers b, on the spindles of which the forward traveling wheels m are mounted, the steering-gear (shown in Figs. 1 and 3) comprises a rod 11, interposed between and connecting the inner arms of the levers b, and a shaft 29, which has a crank q, connected to the rod 71, and is so arranged as to be conveniently manipulated by a person seated in the body D. Said steering-gear, however, forms in itself no part of myinvention, and I therefore desire it understood that any other steering-gear may be employed without involving a departure fromthe scope of my invention.

The rear axle B, Fig. 4, comprises two sections 7', which carry the rear traveling and drive-wheels s and between which is interposed an equalizing-gear contained in a case i. The equalizingear per 86 forms no part of my invention, and I have thereforedeemed it unnecessary to illustrate the same. Between the gear-case t and collars u, loosely receiving the sections *r, are truss-bars 1;, While on said gear-case is a pillow-block w, to which the rear spring a for supporting the bodyD is connected. Mounted on the upper truss-bars 'u and loosely receiving the axlesections 9" are blocks y, upon which are supported by rubber or other springs z'bearings a, provided with longitudinally-disposed apertures b.

The frame 0 is provided at itsforwa'rd end with a longitudinal central horizontal lug c and at its rear end with longitudinally-disposed horizontal lugs d, disposed at either side of its longitudinal center. The lug c is disposed in'the bearing f of the forward axle A and the lugs 61 in the bearings a of the reai axlenli, and consequently it will be seen side.

that the distance between the axles A and B may be increased when it is necessary to take up slack of the chain intermediate of the sprocket-wheel of the equalizing-gear on the rear axle and the engine; also, that the front axle is adapted to rock in the direction of the width of the vehicle, so as to enable the vehicle to run freely on rough or uneven roads and Without liability of the frame 0 being twisted. The arrangement of the springs cl and 2 between the axles and the hearings in which the frame-lugs c d are disposed is advantageous, since said springs serve to cushion the frame C and the machinery carried thereby and prevent the transmission of shock and jar thereto.

As best shown in Fig. 5 of the drawings, the frame 0 comprises a case E and bands F G, arranged in rear of said case and side by In the case E of the frame 0 is arranged a steam-engine F, which is preferably, but not essentially, of the compound type. The drive-shaft a of this engine might be connected with the sprocket-wheel of the equalizing-gear on the rear axle B in any suitable mauner without involving a departure from the scope of my invention. I prefer, however, to transmit motion from the driveshaft of the engine to the sprocket-wheel c of the equalizing-gear on the axle B by the means best shown in Figs. 1 and 2, which means comprises a jack-shaft H, arranged in the case E and having a fast sprocket-wheel d connected by a chain c with the sprocketwheel 0 of the equalizing-gear, and also having two loosely-mounted sprocket-wheelsf g? of different sizes connected by chains g with sprocket-wheels 71 on the engine-shaft a and a friction or other suitable clutch 2' keyed or feathered on the shaft H and designed to be moved, through the medium of a lever 1, into engagement with either of the sprocket-wheels f g and out of engagement with both. \Vhen the clutch 2' is in engagement with the small sprocket-wheel g the vehicle will be driven at a high rate of speed,

and when the clutch is in engagement with the large sprocket-Wheel f the vehicle will be driven at a lower rate of speed; but the power will be increased as is desirable for hill-climbing. \Vhen the clutch i is out of engagement with both of the sprocket-wheels f 9 the engine may be actuated without moving the vehicle to fill the boiler with water or for any other desired purpose. The lever I is carried up into such a position as to enable a person seated in the vehicle to conveniently manipulate t he same, as are also the throttle-lever and reversing-shaft (not shown) of the engine.

In the band F of the frame 0 is secured a boiler J, which is connected by a pipe o containing a throttle-valve b, with the engine F and is equipped with the usual burner-case and smoke-pipe, the latter being connected with the exhaust-pipe c of the engine. In the band G of the frame is secured a watertank K, which is suitably connected with the boiler and contains a fuel-tank L, suitably connected with the burners in the burnercase under the boiler. When desired, an auxiliary water-tank M may be employed, said tank being arranged in the case E of frame 0 in advance of the engine F and suitably connected with the boiler through the tank K or direct, as desired.

N N, Fig. l, are adjustable connections between the bands F G of the frame C and the rear axle B. These connections preferably comprise threaded bolts a pivotally connected to the bands F G and extending through apertured lugs on collars b mounted on the sections 1" of axle B, and nuts c ,mounted on the bolts at either side of the lugs on the collars 12 By adjusting the nuts 0 on the bolts a the distance between the axle B and the jack-shaft H may be readily increased to take up slack of the chain 6 The frame C and the front axle B may be connected toget ter in such manner as not to interfere with the rocking of said axle in the direction of the width of the machine by reachrods R, or in lieu of said rods curvilinear sockets S may be provided on the forward end of the frame 0 to receive the heads of lugs T on the axle A. In either case it will be observed that the frame 0 will be held to the axle A without interfering with the rocking of the latter.

W'hen desirable, the reach-rods R and the connections formed by the sockets S and the lugs T, movable therein,may all be employed, as shown in Fig. 1.

It will be appreciated from the foregoing that in my improved Vehicle the generator, engine, water tank or tanks, and fuel-tank are arranged on the running-gear alone and have no connection with the body D. In virtue of this the body, which may be of any description, may be mounted on springs in such manner as to assure easy riding. It will also be observed that as no part of the body is taken up by the machinery the body may be adapted to carry freight in addition to passengers.

The described arrangement of the machinery on the frame C is very compact, and yet it will be noticed that ready access may be gained to the several parts for the purpose of cleaning or repairing the same.

In practice I contemplate providing the case E of frame 0 with a removable cover (not shown) of metal, cloth, or other suitable material, this with a view of excluding dust, grit, &c., from the working parts of the engine, so as to prolong the usefulness of the same.

\Vhen my improvements are embodied in a large vehicle having a long frame 0, I contemplate arranging a boiler inthe band G as well as in the band F and placing water and fuel tanks in the case E in advance of the engame.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and arrangement of parts,

as such changes or modifications may be made in practice as fairly fall within the scope of the invention as claimed.
