SPECIFICATION forming par-t of Letters Bai-.ent No. 400,522, dated April 2, 1889'. Application iiled April 23, 1888. Renewed December 19, 1888. Serial No.294,ll7. (No model.)
To all whom, it may concern;
Be it known that we, JOSEPH R. VALEN- TINE and ALEXANDER T. GRIGG, citizens of the United States, residing in the city of Pueblo, in t-he county of Pueblo, in the State of Colorado, have invented a new and useful Railway-Motor, of which the following is a description.
The invention relatesto that class of railway and other vehicles which receive locomotion from an engine which is located upon the vehicle itself. v l
The leading object of the invention is the provision of means whereby, when the engine is in operation, the vehicle may be instantly arrested in its progress when in motion, or instantly set in motion when at rest without arresting or retarding the movement of the engine or in any way modifying its action.
The invention consists in the combination, with a vehicle which has two or more pairs of supporting-wheels and an engine mounted upon the vehicle of a pair of driving-wheels which are operated by such engine, and a means whereby the driving-Wheels may either be instantly brought into contact with the earth or with a track-rail to impart motion to the vehicle, or whereby, when in contact, such contact may be instantly discontinuedv to terminate the effective action of the mpelling power.
The invention consists, also, in the connection of the driving-wheel-operating mechanism .with the brake-operating mechanism, whereby the brakes are operated by the same mechanism by which the driving-wheels are held in operative contact with the rail or with the roadway, or are withdrawn therefrom.
The invention consists, also, in other novel parts or combinations of parts, as will be hereinafter described, and then distinctly claimed.
In the drawings, Figure l represents a side elevation of a street-railway car, portions being broken out, which is provided with our improved means of propulsion. Fig. 2 isa top plan view, the body of the car and the brakeshaft and its support having been removed. Fig. is a perspective elevation looking' from the front toward the end of the car. Fig. 4: is
a detail face view, drawn to an enlarged scale, of the bearing-plate and its slidinglink. Fig. 5 is a section on the line .r of Fig. 4.' Fig. 6 is a detail vertical section on the line y y of Fig. l.
As seenv in Fig. l, the engine B, which may be of any suitable or preferred construction, is by preference located upon the,a front portion of the car A.which is provided with front and rear supporting-wheels, w w', of any suitable kind.
Upon each side of the car a bearing-plate, O, having a perforated upper extension, c', and a bifurcated lower extension, c, is secured to an exterior longitudinal sill, C, of the bedframe. The lower extension, c, receives within the jaws c2 c2 of its bifurcated portion the body of a slidinglink, (l, within the opening of which is received the upper and lower members, c3 c4, respectively, of a journal-box, O3, which members have in their coincident faces curved recesses, as shown, to receive the end e of the axle E4 of the driving-wheels E. The coincident faces of the jaws c2 c2 and the corresponding surfaces of the journal-box are slightly curved, as seen in Fig-i, in the arc of a circle of which the engine-shaft is the center. The link d is provided upon its inner and upon its outer face with washers or guides d, which are secured by screwbolts d6, the washers projecting beyond the b ody of the link and overlapping each side' of the jaws c2, as seen in Figs. 4 and 5. The members of the journal-box extend at their ends somewhat beyond the faces of the link in which they are held, and are provided with flanges c5 c5, which embrace the body of the link.
`A spring, cl2, composed of rubber or other suitable material, is secured by pins d4 d5, or other means, within the space between the journal-box C3 and the base dict' the link. A truss-bar, C4, which extends across the lower extremity of the bearing-plate O and islmade fast by its ends vto the sill C, serves to give increased firmness to the bearingplate and the wheel-operatin g mechanism connected therewith.
The upper extremity of the sliding link CZ is connected by a pivot-joint, d, with the lower TOO member,f, of a toggle-lever, l the upper membenj, of which is secured by a pivot-pin,f2, to the upper extension, c', of the bearing-plate C. An actuating-lever, J, having its fulcrum upon the bed-frame of the vehicle, is pivoted at its lower extremity to a connectingbar, l, which in turn is pivoted to a fixed arm, 71., which projects obliquely downward from the transverse rocker-shaft ll, which has its 1o bearings in journal-plates 71', which are secured to the longitudinal sills C. A fixed upper arm, il?, upon the rocker-shaft ll, projects in a direction from su eh shaft opposite to that of the lower arm, 71, and at its upper extremity I5 is pivoted to a bar, G, which extends along the sill C and the bearing-plate C', and is received by its opposite end upon the pivot-pin f3, which connects the members f f of the toggle-lever F. Each driving-wheel E has 2o upon its outer face a circular grooved bearing or chain wheel, E', which receives motion from the shaft l) of the engine B through the medium of the endless chain K.
It will be observed that the driving-wheels have a broad periphery, to permit free lateral movement in rounding curves without liability to dei-ailment. As shown, these wheels are unlianged; but a llange may be employed when desired.
3o ln the operation ot' the raising and lowering mechanism, which will be readily under- I pressibility ot' only three-'fourths of an inch l it follows that the dri ving-wheels cannot,when elevated, be brought int-o contact with such rail by any jolting movement of the car. \Vhen the lever J is released, the drivingwheels, by their own gravity, descend upon the rail, when a very slight foiwvard move- 5o ment of such lever renders the engagementot the wheels with the rail rigid and effective for all purposes. 'lheinclination ot the ways or jaws similarly operates, when the lever .l is thrown backward, to facilitate the elevation of; the drivi11g-wheels.
The lever J, which, as already described, is connected by a series of arms, bars, and levers with the wheel-carrying link (l, is connected also by a chain, l', with a link, Z2, of the brake-chain l, so that when the lever .l is thrown forward to thrust the driving-wheels downward upon the track the brakes L are by the saine movement of the lever released from engagement with the supporting-wheels w y1c', and so that when the drivin g-wheels are lifted such brakes will by the same movement be again brought into contact with such supporting-wheels. It will thus be seen that under this construction both the drivin g-wheels and the supporting-wheels may be wholly controlled by a single operator.
Having described our invention, we claiml. The combination, with a ear, of: an engine which is ixed upon the car, a pair of drivingwvheels mounted in the frame of the car impelled by such engine and movable in ways which are concentric with the axis of the engine-shaft, and a compound lever operable from the en gine-plattorm either to lift the wheels from the track or to hold them in positive and rigid engagement therewith.
2. The combination, with a car, of an engine mounted upon such ear, a pair of driving-wheels mounted upon such car and adjustable up or down in ways thereon, a connection between the driving-shaft of the cnginc and the axle of the driving-wheels, and a lever whereby the driving-wheels are movable either into or out of engagement with the car-track.
In a car which is provided with a brakerod and with brake-chains and brakes, the combination of driving-wheels, an engine, a lever which is operable to adjust such wheels either upon or away from the track, and a chain which connects such operating-lever with the brake-chains, whereby both the driving-wheels and the supporting-wheels are controlled b v a single operator.
