MOTOR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 781,933, dated February 7, 1905.

Application filed May 16, 1904. Serial No. 208,264.

To all whom! if party ('oncm'n:

Be it known that I, \VILLIAM O. Bnowx, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Motor-'lrucks, of which the following is a specification.

The object of this invention is to construct a motor-truck more especially adapted for use with cars or vehicles driven by internal-combustion engines in which it is desirable to transmit varying degrees of speed to both axles upon which the truck is mounted. Since it is necessary in using internal-combustion engines to run the engine at a substantially uniform speed and impart varying degrees of speed therefrom by means of intermediate gears to both axles, great difficulty has hitherto been experienced in constructing a truck which would allow for the swing or movement incidental to the travel of the car and at the same time provide for the perfect operation of the gears. To overcome this diiliculty and provide a mounting for the gear-wheels which will allow for sway and vibration is one of the objects of the present invention.

A further object of the invention is to so locate the engines that they may all drive directly onto the power-shaft by providing a mounting to which the shaft and engines are all secured in fixed relation to one another and at the same time so supporting said mounting that the engines will not be subjected to the strain or stress incident to a support held in unyielding position upon the axles.

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings illustrating the invention, Figure l is a side elevation of the motor-truck; Fig. 2, an end elevation showing one of the axles partly broken away; Fig. 3, a top or plan view, and Fig. 4 a cross-sectional view.

The truck is supported on axles A,mounting the wheels 11, and said axles are rotatably mounted within journal boxes 11', slidably mounted in depending yokes (e of the usual character, and the journal-boxes are provided with pedestals B, to which are secured leafsprings 7), the ends of which are rigidly secured by supporting-rods 1/, which are secured at their lower ends to longitudinally-extending bars B, to which are attached the yokes before referred to. This arrangement provides a resilient mounting for longitudinally-extending bars, which are intended to support the operative mechanism of thcpresentinvention. Between the two wheels are arranged two frames, each consisting of top cross-rails C, carried by and rigidly mounted on the longittulinally-extending bars, to the end of which rails exterior of the bars B are depending supporting rails or bars 0, and the frame in each instance is completed by means of lower cross-rails c, rigidly secured to the depending side bars. The upper and lower rails project outwardly from the side rails, and to the projected portions of the lower rails are bolted casings D of internal-combustion engines, and each casing is provided with end flanges (Z, to which are bolted the engine-cylinders (1, so that each of the casings supports,in fact,two inter nail-combustion engines, which are rigidly carried by the frames, which in turn are supported upon resilieutly-mounted longitudinally-extending bars C, thereby affording a resilient mounting for the engines with respect to the axles of the truck.

The piston-rods of the engines are all adapted to actuate a central power-shaft E, so that four cylinders will operate at different times on the power-shaft, thereby eliminating the necessity for using a large fly-wheel, thereby depending upon the engines rather than the fly-wheel for maintaining a momentum. Upon the power-shaft is loosely located a main differential gear e, adapted to be clutched to the shaft to impart varying degrees of speed by means of any variable-clutch mechanism, (not shown,) the means for controlling the speed of said gear forming no part of the present invention, and said gear meshes with secondary gear-wheels c of lesser diameter, which gearwheels are each carried by secondary shafts journaled within journal-boxes carried bv brackets c",de1.)ending from the longitudinallyextendingsupporting-bars, so that the support for the engine-shaft and the secondary gearwheel shafts will be the same and the gearwheels 6 and a will mesh perfectly with one another. The secondary shafts are connected, by means of universal joints f, with tertiary shafts F, which shafts are rotatably mounted in journal-boxesf, carried by sockets f which latter are rigidly secured to the ournal-box of the adjoining axle by means of a neck f. The opposite sockets are connected by means of a cross rod or bar F, which is loosely inserted into and held within the sockets, allowing a considerable amount of play or vibration to the same. ()u said tertiaryshafts are located tertiary gear-wheels G, meshing with gearwheels 9 on the axles, which arrangement causes the tertiary and axle gear-wheels to mesh perfectly with one another, since they are supported at all times by the same support, so that the rise and fall of the frame supporting the engines and connected mechanism will not impair the meshing of the lastmentioned gear-wheels.

At the ends of the upper cross-rails are sockets H, within which are mounted upper studs it, outwardly extending from links it, at the lower end of which are lower studs if, and said lower studs serve as a mounting for the arms located at the end of supporting crossbars I, which arrangementallows the cross-bars a certain amount of side play or movement which is necessary for the support of the car. The ends of the side bars, as shown by Fig. 1, are connected together by end plates 6, which are bolted or otherwise secured to the crossbars and form, in connection therewith, a box or frame for the support of the car-bolster. Within the space inclosed by the end plates are located leaf-springs J, carried by means of hangers j, which project over the top edges of the cross-bars, and to said springs is secured a bolster K of any usual and well-known type, having in its center a pivot is for pivotally mounting the car thereon. The ends k of the bolster are positioned between the end plates to prevent side movement of the bolster upon the springs, but to allow of this upand-down travel between the end plates the side movement being all provided for by means of the links hitherto described. In order to take up the side play between the journals of the secondary and tertiary shafts and also the side motion caused by the movement of the universal joints in the rise and fall of the frame, it is preferable to mount the tertiary shafts to allow for a sliding movement in the journal.

In operation the power is applied uniformly to the power-shaft by all the engines, and an equal reduced speed may be imparted from the main actuating gear-wheel to the secondary gear-wheels, which are held at all times in mesh therewith by having the same support. The secondary shafts impart power through the universal joints to the tertiary shafts, which have a common mounting with the axle-journal boxes, so that the rise and fall of the axles'will not impair the mesh of the axle gear-Wheels and tertiary gear-wheels. The resilient mounting of the engine provides against impairment by reason of the jolts or jars incident to travel, and the mounting for the car allows for an up-and-down movement and a swinging movement and at the same time provides a perfect pivotal mounting for allowing the car-trucks to turn when necessary. By the use of a single power-shaft, imparting rotation equally in opposite directions, the pull of one of the secondary gear-wheels equalizes that of the other, so that practically all friction is relieved from the power-shaft.

It will be seen from the foregoing description that the parts are all perfectly mounted and located to cooperate with one another and that a perfect meshing of the proper gearwheels is secured without impairing the resiliency of the car or engine-mounting.
