To all whom t may concern,.- j

Be it known that I, SAMUEL N. SILVER, of Auburn, in the county of ndroscoggin and State of Maine, h'ave invented certain new and usefulImprovements in Velocipedes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and usethe same. y

vide mechanism for increasing and decreasing the propelling-power and varying the speed of the machine at the will of the rider. i' A further object of the invention is to provide a velocipede with mechanism whereby power may be applied on `both sides of the axle, thus producing both a pushing and a pulling action to revolve the axle andpropel the machine.

A further obj ect of the invention is to combine with the mechanism for revolving the axle devices for securing a rowing movement in the propulsion of the machine, adapting the latter to be operated both by the hands and feet of the rider orriders.l

With these ends in view the invention consists in the combination, with suitable guides, of an adjustable block connected to the axle and provided with devices for sliding said block within its guides.

The invention further consists in the comliination, with an axle .provided with a drum loosely mounted thereon, of a movable block suitably supported between guides, a band or other iiexible connection between said drum and block, and spring mechanism arranged relative to said drum and adapted to wind said AVO band thereon.

The invention further consists in the features of construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure l represents a plan view of a three-wheeled vclocipede constructed in accordance with my invention. Fig. 2 represents a side view of same. Fig. 3 is a detached view ofthe adj'usrableblock and its supporting-guides and adjusting devices. Figs.

My invention relates to improvements in 1 velocipedes, the object being,primarily, to pro- A. represents the frame of the machine, providedon each side, near its rear end, with pendent bearings c a for an axle or propellingshaft, B, and at its forward end with a sleevebearing, a', to receive the spindle c of a yoke,

C, .the latter carrying a guide-wheel, D, and

by a collar, b, formed upon the axle, and at the opposite side by a ratchetwheeh'b. rigidly secured upon the axle. The drum F, on the side adjacent to the ratchet-wheel b', 'is provided with a pawl, b2, and spring b3 for holding the'pawlin contact with the wheel b".

Upon one side of the drum F is secured one end of a strap, band, or other ilexible connection, G, the other end of the same being secured to the ring or loop h of the adjustable block H. Upon the other side of the drum F is secured one end of a coil-spring, I, the other end of which is attached to the end bar, a2, of the frame.

.l J represents the operating-lever of the machine, fulcrumed on a rock-shaft, K, which is pivotally supported in bearings 7c la of the frame. Thelever J consists of two parallel bars, 7' j, which form guides, between which is arranged the Vblock H, the latter having ilanges or lips to retain it between its guides.

J J represent treadles secured upon arms projecting from each side of the lower end of the lever J.

L represents an adjusting -screw, passing through the upper end block, j', of the lever, i

IOO

provided` with aerank, l, by means of which the screw is turned to adjust the block H near to or away from the fulcrum of the lever J.

M M represent arms projecting from each side ofthe upper end of the lever J, to receive pivotal pendenthandlesN N. The lower ends of the latter are connected by rods n tothe ends of thecross-bar d, to control the guidewheel D.

O represents a riders seat suitably sup-v ported upon the frame.

, The operation of the machine asmthus constructed is as follows: Thelever J is operated by means of the handles N N and treadles J J vmachine and lessen the power, the leverage on the axle is decreased by adjusting the block H away from the fulcrum. Thus the machine may be adapted to roads of diiferentkindsincreased power being obtained for a rough road and increased speed where the road is smooth and even.

In Figs. 7 8, and 9 is illustrated an application of my improvements to a four-wheeled velocipede adapted to be operated by two riders. In these three figures several important modifications of the device illustrated in Fig. l are shown. In this modified con'- structiontwo rotating drums are employed, and two operating-levers, each carrying two adjustable blocks, and having double connec-A tions with the axle and drum-shaft, operating to both push and pull the latter, thus preventing the reaction of the shaft and carryingwheels and avoiding the strain to which the parts might be liable where only single connections were employed.

At A* represent the drums, arranged one on either side of the center'of the axle, the inner' portions, a* at, of said drums carrying the retracting-springs a a, and the outer portions, a an, carrying the beltsor bands B* B5, said bands being wound on their respective drums.

The inner bands, B* B, are connected to the ends of rigid connecting-rods C* C4, the opposite ends of the latter being pivotally connected to adjustable blocks D4D, arranged above the fulcra of the levers F1* E". These levers are of the same construction as the levers shown in Fig. 1, already described, to serve as guides for the block, and are-arranged one on each side of the frame A, and t'ulcrumedl in elongated bearings e* e4 of said frame, to permit a sliding movement of the levers. The outer bands, B5 B5, connect with `blocks F" Ft,

arranged below the fulcra of the levers E4 Ei. The blocks D* D4 are adjusted by means of4 screws G* G'i passing through the blocks and through the top blocks, cl" cli, of the levers, and bearing at their lower ends against the end blocks of the levers. Each of said screws G4 is provided at its upper end with a bevelgear wheel, g4, adapted-to mesh with vertical bevel-gear wheels g5 g5, mounted on a transverse crank-shaft, g, passing through a tube, gi, connecting the levers and carrying the operating-handles HA1 H, connected with acrossbar of the forward guide-wheels by rods h h4. The ends of the shaft gG are providedk with cranks g8. By the construction thus described the driving-shaft is given both a push and pull at each stroke of the levers, and the blocks D* D* may be readily adjusted to or from the fulcra of the levers to vary the power and speed at the will of the riders.

Vhen it is desired to operate the machine by two levers adapted to work independently and alternately, the levers E* may be arranged horizontally beneath the axle.

In Figs. 10, l1, and l2 I have shown a modified form of my improvement, which is adapted to be propelled by alternate movements ofthe feet. In these ligurcs a backbone, A8, and a pivoted bow-brace, BS, are employed, the former supporting the guide-wheel GS, and the latter being connected pivotally to bearings 08 upon either side of the axle D8. The backbone AS is secured upon the axle, and supports the riders seat as. On each side of the backbone is arranged a propelling le'ver or treadle, E8, fulcrumed on a shaft, es, supported in bearings of a depending frame, FS. These levers carry the adjustable blocks Gs Gs and Gr9 G9, to which are connected the straps H H8 and their connections, these being two straps for each lever, wound upon each other.,

Fig. 10, upon thev drums I8 IS, secured loosely upon the axle DS, and each provided with a coil-spring, J8, arranged upon drums, and secured at their outer ends to a cross-bar, K8, below the axle. VThe ends of the straps H are secured, respectively, .to the blocks Gr8 Gf8 and to rigid connecting-bars hJ h, the'latter being secured to the remaining blocks, G G.. The

lbackbone Aa carries at its lower end a guidewheel, C8, operated b a handle M8 arranged adjacent to the` seat of the machine, and supported upon the backbone by suitable braces,

its lower end withabevelgear wheel, gm, meshing with that ofthe shaft and adapted to ad-i just the blocks when the crank is operated.

In Fig. 13 is illustrated a further modification of the devices for adjusting the blocks for varyingthe leverage upon the axle. In this device the blocks are provided with a rack, o,

having a gear-pinion, om, arranged between them and adapted to be operated by any preferred means to adj ust the blocks. The blocks and racks are` provided withV grooves to fit within the levers and be guided therein.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
