SPECIFICATION forming. partof Letters Patent No. 703,594, dated July 1, 1902. Application filed April 19, 1901. Serial No. 56,600. (No model.)
To aZZ whom it may concern: 7.
Be it known thatl, PAUL 'J. KAMPER, a
citizen of the United States, residing at Sioux I City, in the county of Woodbury and State of Iowa, (whose post-office address is Sioux City, Iowa,) have invented a new and useful Improvement in Hand-Motors; and I do dea means of propelling the vehicle which will enable it to attain a much higher speed than ordinarily possible and atthe same time toreduce the amount of power required. These objects I attain by the construction shown in the accompanying drawings, forming a part of this application, in which- Figure 1 is a sectional elevation of my invention, taken on the line B Sin Fig. 2, showing also the front wheel and part of the frame of the motor. Fig. 2 is a half elevation of the Working parts looking in the direction of the arrow in Fig. 1, the line Y X being the center line of the vehicle. Fig. 3 is a sectional view of pawls, cam-ring, and lever, taken on line V W of Figs. 1 and 4:. Fig. 4 is a plan elevation of lever, showing parts of cam-ring and pawl cut away. Fig.5 is a sectional view of clutch and shaft taken ,on the line U Z of Fig. 2.
Referring now to the illustrations, in which like parts are designated by similar letters of reference, A A is the frame or body of the vehicle.
13 B are the rear wheels, and C C the front wheels.
D D is the elevated framework from which the operating machinery is suspended.
T is a seat located upon the front" of the elevated framework.
H is a shaft running parallel with the axles and located near the central part of the vehicle, the ends of the shaft revolving in suit- 1 able bearings attached to the frame A. I is a ratchet-wheel firmly secured to said shaft at the center. A lever J, forked at the lower portion, embraces said ratchet-wheel between the lower ends of said forks, and the shaft H extends through the lower ends of said forks and is adapted to revolve therein. Pivotally secured to said l'ever at the lugs a a, respectively, are two pawls K and K, which are adapted to engage the ratchet-wheel I. Said pawls are made to engage the ratchet-wheel by means of a spring 1), extending between the upper ends of said pawls, Fig. 3, and either of said pawls may be thrown out of engagementwith the wheel by means presently described. A link L is pivotally secured to the upper end of said lever, J and a lever M, having a handle M, is also pivotally secured to the opposite end of said link. The lever M is pivotally situated upon a shaft 6, extending between the upper extremities of the frame D. The lever J is a jointed extension of the link L, and the pawls are freely jointed at the points a a to said lever J. The lower ends of the pawls are adapted to abut against the teeth of the ratchet-wheel for the purpose of imparting a continuous motion to said wheel, the levers being reciprocating drivers of the pawls, which in turn impart the motion to the ratchet-wheel. Firmly secured to the respective sides of said lever M and adapted to turn on said shaft 0 are chainwheels ff. Situated upon the shaft H on either side of the ratchet-Wheel and under the wheels f f in the same plane are chainwheels G G, adapted to-revolve upon said shaft, said chainwheels having ratchetclutches. Near the ends of the shaft H, within the frame, are large chain-wheels h h, which are firmly secured to said shaft and turn therewith. Ratchet-clutchest t, adapted to engage with the clutches upon the wheels G G, are keyed upon said shaft H by means of the lugs 15' t and turn therewith, being capable of sliding thereon. The coilsprings 01 i, abutting against the collars s s, secured to said shaft I-I, force said ratchets together, and the collars a" 9:, secured to the shaft H on the opposite side of thewheels G G, hold said wheels fi'rmlyin position. The rear wheelsare firmly secured to the axle O, which revolves in suitable bearings upon the framework. Firmly secured to said axle within the frame in the plane of the wheels h h are the chain-wheels P P. Chains l ZeX- t-end, respectively, from the chain-wheels ff to the chain-wheels G G, and chains on on extend from the large wheels h 71 to the chainwheels P P upon the rear axle. WVhen the lever M is raised to a vertical position, the chain-wheels ff, secured thereto, are turned forward, and the chains Z Z cause the wheels G G and the large wheels h it to turn in the same direction, while the chains in m impart the same forward motion to the wheels P P, which causes the rear wheels to turn forward. As the lever M is brought toward a horizontal position the chain-wheels G G are turned backward upon the shaft H, slipping past the ratchets. As the lever M is brought down the lever J assumes a vertical position, and if the forward pawl is engaged the ratchetwheel I is turned forward, and being firmly secured to the shaft H a forward motion is imparted to the vehicle. In Fig. l of the drawings the front pawl is shown engaged, which would cause a forward motion of the vehicle. The driving means consist of both the pawls and the chains attached to the chain-wheels, both being operated by the lever M. IVhen the lever M is lowered, the pawl operates, and when raised the chainwheels are utilized. The ratehets permit the shaft II to revolve free of the chain-wheels. When the lever M is brought down, the chain-wheels G G are turned backward, thus moving in the opposite direction from the shaft H and slipping past the ratchets t 25. As the ratchet-wheel I has a continuous motion, the pawl slips over the wheel when brought to a horizontal position for the purpose of resuminganew contact with the teeth of the wheel. The upper part of the leverJ is encircled by a movable cam-ring 6, having a lug or extension 6 projecting downward and adapted to press upon the upper end of either of said pawls, which forces the opposite end of said pawl out of engagement with the wheel I. By turning the ring so that the lug is not in contact with the pawl the free pawl is engaged with the ratchet-Wheel and the vehicle propelled in either direction.
My invention is especially adapted for use upon railways as a hand-car, and if so used the running-wheels of the vehicle should be provided with flanges. I do not, however, limit myself to this particular adaptation, but claim for my invention the right to its exclusive use upon any kind of road orhighway. Neither is my invention limited to the particular construction here shown or described; but it is applicable to any form of vehicle where propelling power is used.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A horizontal shaft secured to the frame of a vehicle adapted to revolve in suitable bearings thereon, a ratchet-wheel secured to said shaft, pawls abutting against the teeth of said ratchet-wheel, an operating-lever pivotally secured in bearings supported by the frame of the vehicle, levers connecting said operating-lever with said horizontal shaft, said pawls being pivotally secured to the lever connected to said shaft, the end of said connecting-1e ver freely encircling said shaft, in combination with chain-wheels firmly secured to said operating-lever, chain-Wheels freely encircling said horizontal shaft, said last chain wheels having ratchet clutches adapted to enmesh with ratchet-clutches secured to said horizontal shaft and adapted to slide thereon, springs for pressing said ratchets into engagement with each other, chains connecting the wheels on said horizontal shaft with the wheels secured to said operating-lever, and means for imparting the motion of said horizontal shaft to the axle of the vehicle when the shaft is turned, substantially as described.
In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.
