PEDOCYCLE.

Specification of Letters Patent.

Patented Aug. 1,1911.

Application filed March 6, 1911. Serial No. 612,515.

To all whom it may concern:

Be it known that I, MIHKEL KoPrnL, a subject of the Czar of Russia, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Pedocyoles, of which the following is a specification.

My invention relates to improvements in pedocycles, the object of the invention being to provide improved means for propelling one of the wheels, said propelling means operated by the weight of the user, who alternately applies his weight first upon one foot, and then upon the other.

A further object is to provide an improved wheel comprising two members inclosing a train of gearing, and a frame-supporting the gearing with improved means for moving the frame and imparting rotary motion through the train of gears to the wheel.

A further object is to provide an improved propelling wheel in connection with a frame, and a foot sup-porting platform, said platform connected with the frame by means of toggle levers mounted to slide in the frame and footrest, and permit the foot rest to raise and lower and transmit rotary mot-ion to said wheel.

. With these and other objects in View, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims. 1

In the accompanying drawings: Figure 1, is a view in side elevation illustrating my improvements. Fig. 2, is a plan view showing the foot rest broken away to illustrate the parts below. Fig. 3, is a view in elevation on an enlarged scale of the propelling wheel with one side of the wheel removed. Fig. 4, is a view in vertical section through the propelling wheel. Fig. \5, is a view in section on an enlarged scale on the line 5-5 of Fig. 1. Fig. 6, is a similar View. on the line 6-6 of Fig. 1, and Fig. 7, is a detail view illustrating the manner of connecting one of the fork arms 3 with the sleeve 34.

In constructing my improved device, I provide a longitudinal bar 1, which is provided at its front and rear ends with forks 2 and 3 respectively, to receive the journal bolts 4 and 5 respectively, on which the front and reafwheels 6 and 7 respectively are mounted. These journals are secured by nuts 8, but other means for securing them may be provided as desired.

9, represents a foot rest to which the foot 10, illustrated in dotted-dines, may be secured by a strap 11 and toe clamp 12, both of which are adjustable on the foot rest by means of brackets 13 and thumb screws 11 to adjust them in accordance with the size of the foot, but the invention is of course in no wise limited to the shoe securing means, as any may be provided that is adapted for the purpose. The foot rest 9 at its rear end, is provided with depending perforated cars 15 to which links 16 are pivotally connected by a bolt 17, a suitable spacing sleeve 18 being positioned on the bolt between the ears 15. This bolt is held in place by means of a nut 19, and the links 16 above referred to are keyed to the rear journal bolt 5. The foot rest 9 and bar 1 are connected by toggle levers 20, which are pivotally connected centrally between their ends by a pin 21, and at their rear ends are connected respectively to the foot rest 9 and bar 1. One of these levers 20 is pivotally secured to the,,sleeve 18 as shown at 23, and the other is -pivot-ally connected to bar 1 as shown at 24. The forward ends of these levers 20 are provided with cross pins 24*, which are positioned in flanged guides 25 and 26 respectively, the former being secured to the bottom of foot rest 9, and the latter forming an integral part of bar 1.

The rear wheel 7 comprisestwo members 27 and 28, which are preferably of sheet metal, and have their edges bent inwardly and overlapped as shown at 29, and these inwardly bent portions of the members form a rim for the reception ofa tire 30, preferably of rubber, but of course may be of other material. are rigidly connected by bolts 31 and nuts 32, so as to compel them to turn together These members 27 and 28 are held in engagement with the teeth of ratchet wheel 33 by springs 37, so that while the gear 35 is free to turn on the journal in one direction, it is held against movementin the opposite direction by means of the pawls.

A triangular frame 38 is provided with an inwardly projecting arm 39, having a hearing 40 which is keyed to journal 5. This frame 38 supports a train of gearing 41 which connects the gear 35 with a pinion 42 fixed tomember 28 of wheel 7. The wheel 7 is supported on suitable ball bearings 43, and is mounted to turn loosely and with as little friction as possible. It is of course to be understood that one of these devices will be provided for each foot, and the operation is as follows: Assuming the parts to be in the position shown in Fig. 1, when the operator puts his weight upon the foot rest 9, said foot rest will move downward, causing the toggle levers 20 to ride forwardly in the guides 25 and 26. At the same time, links 16 will swing downwardly in the are of a circle, turning journal 5. This movement of journal 5 causes frames 88 to move, and as the ratchet wheel 33 is held stationary and the pawls 39 are in engagement therewith, gear wheel 35 is held against rotary movement in this direction, so that the movement of frame 38 compels the train of gearing 41 to turn, and transmit a high speed to pinion 12 and the wheel 7. The momentum of the wheel, when the weight is released on foot rest 9 while it is being applied to the other device, attached to the other foot, will compel the train of gears 11 to continue their movement, which will cause gear 35 to turn, and will permit the foot rest 9 to rise, which movement is compensated for by the pawls 36, riding on the ratchet wheel 33;

\Vith a device of this kind, a high speed may be attained by alternately placing the weight first on one foot, and then on the other, and this alternately shifting of the weight necessitates but slight exertion on the part of the operator, and he may attain any speed desired in accordance with the rapidity of such motion.

While I have shown the front wheel 6 smaller than rear wheel 7, the invention is in no wise limited to the relative sizes of these wheels, nor is it limited to any particular number of wheels, save that one of said wheels must constitute a driver as above explained.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
