Specification of Letters Patent.

Serial No. 521.526.

T 0 (db whom it may concern:

Be it known that I. l nmnn1'( u[ KLmN- voonL, a citizen of the United States of America, and resident of Newport. in the county of Campbell and State of Kentucky, have invented certain new and useful Tmprovements in Vehicles, of which the following is a specification.

This invention relates to certain new and useful improvements in vehicles designed primarily for use in transportation or delivery of light articles, the device. as herein illustrated, being shown as designed for actuation by foot power. but it applicable to other means of propulsion and to other uses such for instance as operating machin cry.

The present invention aims primarily to produce a simple and efficient. easily driven vehicle in which a plurality of levers are so attached that through the same a pressure or power is produced through the medium of the crank shaft without interruption, so that the dead center or point will be passed. the pedals or analogous portions being designed to be given more than a half revolution at each depression of the treadle. The means whereby this end is accomplished is simple yet etiicienti. durable. and reliable in its action.

The invention has for a further object to provide means whereby. when the vehicle turns a curve. an alarm is automatically sounded as a 'arning to persons. in order to avoid collision and accident. T provide n'ieans whereby when the vehicle is caused to turn to make a slight curve 0' a larger curve around a corner. for instance. the lever on one end of the driving axle will be caused to engage or ride over the cooperating ratchet and a more or less sound or signal will be given by the bell. If the vehicle moves on without power. after the. pressure on the pedals is removed. then the levers will be driven over the two ratchet wheels and a signal sounded. Means are provided for throwing out the bell when desired.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings. which. with the numerals of reference marked thereon. form a part; of this specification. and in which- Figure 1 is a side elevation of a device embodying my present improvements with a portion broken away. Fig. 2 is a top plan view. Fig. 3 is an elevation of the front axle with the ratchets and other portions shown in section. the front wheels and other portions being broken away. Fig. 4 is a pers wctive detail showing the bell and its actuating lever detached.

Like numerals of reference indicate like parts in the several views.

Referring to the drawings. 1 designates the front axle and 2 the front. wheels thereon. 3 is a sprocket wheel, and -t are ratchet wheels fast one upon each end of said axle outside of the wheels 2. The wheels 2 are loose upon the axle for a purpose which will hereinafter be made apparent. The axle 1 passes through a sleeve surrounding the same. The wheels 2 and the sprocket 3 are fast on this sleeve so that the sprocket revolves the wheels 2. I

5 is the rear axle and (3 the rear wheels thereon.

T are guards for the rear wheels which may be attached in any suitable manner to the side bars t.

t) is the frame of the truck of any suitable construction. the center longitudinal bar 10 thereof being raised or elevated and rising therefrom is the seat post l1. '12 being the seat supported thereon on suitable springs 13.

H is a shaft mounted in suitable hearings on the elevated central beam 10 and fast on this shaft is a sprocket wheel 15. around which passes a sprocket chain 16. which pass-es around the sprocket wheel 3 on the front axle. whereby motion is communicated to the latter. On the shaft 1+ are the cranks 17 and 18 oppositely disposed and provided with the lateral terminals 19. on which are the rollers 20 loosely mounted thereon and held in any suitable manner. as by nuts or the like. upon the ends of the portions upon which they are n'iounted.

To the rear cross member 21 there are pivotally mounted. as at 22. the levers or foot pedals 23 and 24-. The forward ends of these foot pedals have the rests 25 for the feet. and to the rear thereof is journaled in each pedal a wheel 26. beneath each of which passes a chain 27 or the. like. one end of which is connected in any suitable manner, as at 28. to a cross bar 29 at the rear of the machine. inch chain passes beneath a triangular mcmber 30. being secured thereto 1 near its forward end, as at 31, in any suitable manner, the said triangular member 30 being hinged to the under side of its member 24, as seen at 32 in Fig. 1. The rear end of the triangular member has a lug 33 with a slot through which the chain passes. The forward end of the chain :27 has a sliding connection with an inclined rod 34, seen best in Fig. 1, which is socured to the under side of a pivotally mounted arm 85, whose pivot is at 36 on the rear cross bar 37 of the truck. The under side of each of the pivoted members 35 is provided with a curved or cam shaped portion 38, as seen best in Fig. 1, which is designed to rest upon and have contact with the roller 20 of the crank arm, as will also be readily understood upon reference to Fig. 1.

The rear portion of the frame of the truck is mounted upon springs, as 39, as seen in Fig. 1.

With the parts constructed and arranged as above described, the operation of this part of the invention will. be readily understood. The foot treadles are so arranged that when one up, the other is down, and, as the pivoted members 35 rest upon the rollers or rotatable sleeves 20 of the crank arms, as power is applied to the pedals, the downward movement of one causes the pivoted arm 85 to bear upon the roller 20 of its crank arm, thus causing the shaft is to revolve. The movement is such that the shaft is given more than a half revolution at each downward depression of the pedal and pressure or power is produced on the crank shaft without interruption, so that no dead center is, encountered, the crank passing the dead center upon each downward movement of the pedal. Alternate up and down movements of the pedals gives continuous revolution to the shaft 1st and through its sprocket wheel and the sprocket chain and the sprocket wheel on the front axle propels the vehicle. The sliding connection of the forward ends of. the chains with the members 3st on the pivoted arms 35 allows of the increased movement. The triangular members provide for the proper lifting of the pedals and for the proper actuation of the pivoted members 35, as power is applied to the pedals. The rollers, in connection with the curves upon the under faces of the pivoted members 35, serve to insure minimum friction of the parts so that case of movement is assured.

The device is provided with a suitable guiding handle 40 carried by the stem tl, suitably mounted in the forward portion of the truck or frame of the device, and, at its lower end, this stem carries a yoke 4-2, in which is supported a transverse rod 43, to opposite ends of which are connected the rods 4:4: which are crossed at substantially the midlength of the device, as seen best in Fig. 2. The forward ends of these crossed rods have suitable connection, as by chains 4L5, with the lateral members 46 secured to the rear ends of the side bars 8, by means of which the vehicle may be guided.

On each front wheel, I secure a bell 47,

the hammer arm -18 of which has detachably connected therewith a rod or the like 49, the free end of which is connected in any suitable manner to a member 50, hinged at 51 to a plate or the like 52, which may be secured in any suitable manner to the wheel, as, for instance, to one of the spokes 53, or to a portion of the hub, or in any other suitable manner. This plate 50 is designed to, at times, cooperate with the ratchet 4- to sound an alarm. 5t is a spring arm designed to bear upon the member 50 but adapted to be thrown up or out of engagement with the said member 50, when desired. The construction is such that under normal conditions, that is, when the vehicle is moving in a straight line, no alarm will be sounded, but when the vehicle turns a curve or corner or deviates from a straight line, then the wheels 2, being loose upon their axle, the member 50 rides over the iatchelwand the alarm is sounded once at each revolution of the wheel. The faster the vehicle moves or the greater the curve, the greater the alarm. Should the vehicle continue to move, after power is removed from the pedals, then the members 50 will be driven over the two ratchet wheels and both alarms will be sounded. It to be understood that the front wheels, being loose upon their axle, when the vehicle turns a, corner or moves upon a curve, the alarm on one wheel will be sounded. Vhen. turning a curve in the oppositc direction, itis the alarm upon the other wheel that is sounded. hen the pedals a re at rest and the machine goes forward in a straight line, the alarms on both wheels will. be sounded.

Ivlodifications in details may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.
