.To all whom it may concern..-

Be it known that I, SAMUEL llIARTIN, of Mill Rock, in the county of Oolumbiana and State of Ohio, have invented certain new and useful Improvements in Tricycles, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved tricycle,which can be propelled by one, two, or more persons, and is especially adapted to attain a great rate of speed and to carry passengers or freight.

The invention consists of two drivingwheels actuated by hand and foot levers and suitable ratchet-wheel connections, of a shaft on which is mounted the driving-gear, a swinging frame and seat, of a guide-wheel mounted in turning bearings held in place by suitable connections from the main axle, of a device for operating the guide-wheel, and of a brake of special construction.

The invention also consists of various parts and details, hereinafter more fully set forth and claimed. I t

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View, partly in section, of my improvement. Fig. 2 is a longitudinal vertical section on the lines 00 w of Fig. 1. Fig. 3 is a vertical cross-section on the lines y y of Fig. 1. Figs. 4 and 5 are detail views of the drivingwheel hub and ratchet-block. Figs. 6 and 7 are detail views of the ratchetwheel. Figs. 8, 9, and 10 are detail views of the lever and wheel carrying the sliding ratchet-wheel pawls. Fig. 11 is a sectional plan view of the guide-wheel fastening. Fig. 12 is a longitudinal vertical section of the machine, the guiding-wheel and connections being detached and parts broken away. Fig. 13 is a front elevation showing the frame and brake system.

The main shaft A is provided near each end with the hubs B B, turning loosely on the shaft A, and on which hubs B B are mounted the driving-wheels O O. The hubs B B are provided with recesses B on their outer faces, in which recesses B are formed the ratchetteeth B. The shaft A projects into each recess B with its square ends A A, on which are secured the ratchet-blocks D, having each a recess, D, in which slide the pawls D", and held in contact with the ratchetteeth 13 by the force of the coiled springs D placed in the recess D between the axle end A and the pawls D A cover, D, is placed over the outer open face of the hub B, and secured by the nut D screwing on a bolt formed on the extreme end of the shaft A. This. cover D protects the ratchet-block D from dust and mud. Next to the inner edge of the hub B is placed on the shaft A the sleeve E, provided on its rim with a screwthread, on which is screwed the frame-block E. to which is attached the main frame F. The frame F consists, principally, of the horizontal arms F, attached to the frameblocks E of the horizontal connecting-rod F, from which project downwardly the stays F on the lower end of which is hung the front end of the swinging platform G.

To the rear end of the frame-block E are secured the forked stays F*, to which are attached the upright rods F to the lower end of which is hung the rear end of the swinging platform G, and which rods F are connected by the horizontal connecting-rod F- To each of the arms F is attached an upright rod, F which is onits lower end connected by the rod F with the arm F, and on its upper end by the stay F to the upright F and by the inclined stay F to the connecting-rod F. The lower ends of the upright rods F F are connected to each other by the horizontal rod F, and the lowerends of the vertical rods F F are connected to each other by the horizontal rod F.

To the cross-rods F", F, and F are pivoted the bent rods G, to which are pivotally connected the arms G attached to the under side of the swinging platform G.

Next to the sleeve E on the shaft A is placed the wheel 'H, carrying the four or more pawls, H, sliding in sleeves H, formed on the wheel H, and held in contact with the ratchet-teeth 1, formed on the outer face of the ratchet-wheel I, by the force of the coiled springs H The wheel H is provided with a hub,H, in contact with the inner edge of the sleeve E, and around which hub H is placed A in any suitable manner, and is provided on each face with the rat chet-teeth I.

On the hub l of the iat'cliet-wlteel I is placed the belt-pulley J, which turns on the same, and-is prevented from slipping off the said hub I" by the nut 1 screwed on the inner end of the hub I". The belt-pulley J is provided. with sleeves J, in which slidethe pawls J", held against the ratchet-teeth,l formed on the inner side of the ratchet wheel I, by the force of the coiled spring J It will be seen that the ratchet-teeth 1, formed on each face of the ratchet-wheel I, are engaged on the outer edge by the sliding pawls .H of the wheel H, and on the inner edge by the sliding pawls J of the belt-pulley J.

To the connecting rod F are pivoted the lower ends of the levers K, which extend in an inclined position upward,and are provided with the handles K. To each of these levers K is attached the end of a belt, K*, which passes downward and overa pulley, K placed on the cross rod F-,and upward over the beltpulley J, to the rim of which the other end of the belt K is attached.

To the belt K is buckled a short strip, K, of leather or other material, to which strip K is attached the stirrup K having a foot-piece, K, and sliding on the inclined rods G, attached to the platform G. It will be understood that by raising the levers K, in the direc tion of the arrow a, and at the same time pressing the stirrups K which slide on the rods Gr downward, it will cause the pulley J to turn on the huh I of the ratchet-wheel I by means of the belt K". The coiled spring K attached to the rod F", will assist the lever K to resume its former position on the returnstroke of the same in the direction of the arrow a.

To the belt-pulley J is attached one end of a coiled spring, J, the other end of the same beingsecurcd to a forked brace, J which has its lower bearing on the cross-rod F, and its upper forked end being placed over the shaft A. This coiled spring J assists the lever K to assume its former position on the returnstroke in the direct-ion of the arrow a. Rods G, similar to rods G", cxtendfrom the rear of the platform G upward, and they and the rods G carry the seat G which is thus suspended centrally in the middle above theaxlc A, and conveniently large to adtnit two or more persons. The guide-wheel L is m unted in segmental pieccs L, which are provided on their outer rims with grooves L, in which fit the blot-ks M. bolted to the castings M, which are held in position by the inclined stay-rods M secured to the main frame F at the horizontal cross-rod F, and additionally braced by the rods M, extending from the forked rods F to the cross-rod F, and from thence to the castings M;

To the shaft L of the guide-wheel L are attached the outer ends ofthe forks N of the lever N, which imparts a turning motion to the guide-wheel L by the device now to be described.

To the horizontal cross-rod F is secured the curved rack 0, provided with the teeth 0, in which engages the pointed pawl O, placed on the lever-frat'ne P, and held in contact with theteeth 0 by the force of the spring 0 The lever-frame P is provided with the handle I and the two small rollers 1? P", pivoted to the frame P, one at each side of the pawl O", and resting against the edge of the rack 0, so that when the handle I? is moved to either side it will cause the pawl O to disengage the rack O, and at the same time will swing the lever N sidewise. and consequently turn the guide-wheel L. The lever N may be locked in such side position by allowing the pawl O to again engage the respective teeth 0 on therack O. the handle I? and the frame P projecting radially front the guide-wheel L.

-To the outer ends of the horizontal rods F are attached the brakes Q Q, one for each driving-wheel 0. Each of the brakes Q consists, principally,of the brake-frame Q, to the upper end of which is attached the forked brake-shoe Q The brake frame Q is provided with a slot, Q, through which passes the cross-rod F so that when the brake-frame Q is pressed downward the brake-shoe Q is forced against the rim of the drivingwvheel C. The lower end of the brake-frame Qissecurcd to alever, U, pivotally attached to the lower cross-rod, F. This lever U is also provided with brake-shoes U, and is held in its normal" position, as shown in Figs. 12 and 13. by a spring, U", attached to the lever U and the cross-rod F; The. levers U are connected with each other by the arms U and the crossrod U. It will be seen that by pressing the cross-rod U downward.with the feet it causes the brake-shoes Q and U to engage the rims of the wheels 0, and when the downward pressure on the cross-rod U ceases then the springs U will force the levers U to their former position. thereby releasing the brakeshoes Q and Ufrom the rims ofthe wheels 0.

The operation is as follows: The le ers I l are raised frotn their normal position (shown in Fig. 12) and are moved upward by the operator in the direction of the arrow b until they assume the position shown in Fig. 2. The levers H are then moved downward by the operatorin the direction of the arrow b", which causes the ratchet-wheel I. and consequently the shaft A, to rotate. The shaft A receives a similar motion by means of the lever K, the belt K, and the stirrup K by raising 'tltelever Kin theinvcrse direction ol'thearrow to, causing the belt-pulley J to rotate, which transmits its rotation by means of the pawls J to the ratchet-wheel I, and the latter, being secured to the shaft A, causes the shaft A to revolve, and consequently the driving-wheel O by the arrangement in the hub B, as before described. The levers H are operated by one person standing on the swinging platform G, and the levers K are simultaneously raised with the hands of another person seated in the seat Gatthesametimethatthe feet ofthis operator, placed in the stirrups K", press the latter downward, thus transmitting double power to the belt-pulley J. The action of both operators on the levers H and K and the stirrups K causes the shaft A to revolve in the same direction, and thus propel the machine forward by the united power of the two operators.

The swinging platform G affords easy riding on driving the tricycle over uneven or rough ground.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent? 1. In a tricycle, the shaft A, the ratchetblock D, provided with the slot D, thesliding pawls D the springs D the hubs 13, and the driving-wheels 0, all arranged as shown and described.
