Be-it known that I, EPHRAIMHERRINGTON, a citizen of the United States, residing at At- 1anta,in' the county-of Fulton and State of Georgia, have invented certain new and useful Improvements in Tricycles; and I do de- V clare the followingto-be a full, clear, and exstructionof the same as hereinafter shown and described, my improvements being more especially adapted for the class known as tricycles. v

In the accompanying drawings--Figure 1 represents a plan view of a tricycle provided with my improvements. Fig. 2 is a plan illustrating the propelling mechanism. Fig.3 is a side'view of the improved tricycle. Fig. 4 is a side view, partly in section, of the seat and toggle arms connected therewith, and other details; Fig. 5 illustrates the bearing boxes of the-rear axle in transverse section. 'Fig.6 illustrates in section the bearing. box in the forward wheelof the vehicle. A Fig. 7 shows a I 4 modification in construction of the bearing boxes. 'Fig. 8 shows in vertical sectionone of tions.j

the travelers which are connected withjthe motorsprings. Fi .9illustrates a lever, conv nectedwith the shaft of a drum, andconnec- 'Adesignates the main frame on which is o a platform B, The-two rear wheels O of the tricycle are on an axle a which is mounted in bearing boxes 12, secured to the said frame.

Underneath the platform B, are placed a series of spiral springs. c, in position parallel with each other, being separated by the'slats; dr Iwo guide-rods c are passed through each off-thesprings a longitudinally and are fas-:

tenedat' their extremities to theframe' work. Connected with each of'the springs c atone. end, is a plunger-block or travelere, in which is mounted a pulley e, the said traveler-haw: ing movement betweenthesaid uide-rods.

As seen in Fig. 2, the travelers e are arranged to move alternately in opposite directions when the springs c are either expanding or being compressed. A cord e hasone end fas; tened to the frame at fand is passed about the pulley e in the nearest travelere; from thence the said cord is passed to and about said drum being loose on a shaft g,imounted.

in the rear part of the frame A. The drum D has a ratchet h fast on one end ofthe drum, and attheopposite end is a ratchet h which is fast on said-'shaft'g," a pawl i servingto prevent backward rotation of the drum on said shaft. v A

E indicates a lever, the lower endof which is loosely connected with the shaft g, near the ratchet wheel 71, on said shaftr Nearthehandle end of the lever E, is pivoted a bent finger piece It, and rearward therefrom, on saidle+ ver, are severally mounted two pulleysland Z, said'pulleys being in line asshow'nyand a pivoted bent lever m is also mounted onlever E, in line with the said pulleys, the lower end of said lever m being raised by asprin'gn. A pawl n is connected with the leveriE, near the lower end of the latter, said pawlbeing in position to be pressed by pivoted leverminto connection with the ratchet h of. the drumD. A cord n is connected with .thefinger :piece is, and passed under the pulley Z, over thepulley Z and connected with the pivoted, bent lever m.

Aswill be seen, the lever Eis located near the seat F, and when the operator grasps-the handle of said lever, pressing the finger piece 70, the cord is drawn so' as to actuate the pivotedlever-m, and the latteripresses down the pawl n' into connection with the ratchet h of the'drum D.: Thus the operato.r,:by suc- 'ces sive' movements of the lever E, may rotate the shaft gand windthe cord each the drum communicatedi to the axle 'a,throu'gh;the;fol-

loWing descI- ibed .gearing..:i Loose on. shaft-Lg is a gear-wheel m which is prevented from rearward rotation by a pawl 97. which engages a ratchet wheel 0 which is fast on said shaft. The gear-wheel m connects with a pinion r, on a shaft 7", mounted in the frame-work, and on the shaft r is a gear wheel r which engages a gear wheel Won the axle a, of the carrying wheels 0.

The propulsion of the vehicle may be assisted by the operator sitting in the seat F which is mounted on two spring arms or standards G, the lower ends of which are loosely connected with the shaft g, and are constructed to straddle two ratchet wheels 0 on said shaft, two pawls 0 connected with arms G, being in position to connect with the ratchet wheels 0'. The toggles I connect the seat F with the platform B, and pivotally connected with said toggles is a bent arm or connecting bar 19 which extends forward between the "pedals p which are pivotally mounted on lugs fastened to the platform B.

J indicates a lever in position forward of the seat F, and having at its lower end a short arm 11 extending rearward. Near the elbow a: formed by the arm 19?, the latter is pivoted to theforward ends of the pedals p and also to the connecting bar 13, and the arm 19 near its rear end is pivotally connected with the lugs which carry the pedals.

The operator places his feet on the pedals p and with his heels bears down on the rear ends of the pedals and at the same time pulls back the lever .l, the seat being thus raised somewhat by the action of the toggles I, and the pawls 0 being also raised on the ratchet wheels 0', and connecting therewith; he then with his feet presses down the forward ends of the pedals and moves the lever J forward, by which action the seat is depressed and the pawls 0 engaging the ratchet wheels 0' on shaft 9, rotate said shaft or assist in suchrotation.

The forward wheel H of the tricycle'is.

mounted in a bifurcated standard L, which has a loose connection with an arm or bent standard K which extends from the frame A, the standard L having a stem 8, extending through an aperture in the arm K. A short arm 5'' is fastened to the stem 5, and when the vehicle is going directly forward, the arm 5' extends directly forward.

To the bent standard K is fastened a crossbar 8 in the ends of which are mounted the pulleys .9 At each side of the platform B is a frame or standard M in which is mounted a shaft s having a crank s on its inner end;

and on the shaft 8 is a chain wheel N which I may be connected with theshaft by ratchet j and pawl r4, and is connected by a chain belt I O with a chain-wheel N on the hub of one of the carrying wheels 0. On each of the shafts s, at its outer end, is a spool or drum 8 which is loose on the shaft but may be connected therewith by a ratchet and pawl s", so that the operator by turning a crank 8 forward, may

impart motion to the chain-wheels N, N, without rotating the spools s; but when he turns either of the cranks s backward, the spool s is connected with the shaft by ratchet and pawl s and is rotated with said shaft. The cords if are fastened to the arm .9 on the stem of the standard L, and said cords, extending in opposite directions, are passed about the pulleys on the ends of the cross-bar to the drums s on the shafts s. The cordst are made somewhat elastic by the springs 11., connected with them. To the drums s, the other cords t are attached, each of which is passed under a pulley 7.6, which is carried by an arm extending from a standard M, and attached'to the upper end of a pivoted lever P, carried by an arm R of said standard. The lower end of each lever P grasps one half of a clutch v, keyed to the axle a, the other half of said clutch being formed on the hub of a carrying wheel 0.

When the operator desires to turn the vehicle to the right, he turns the cranks, at his right, backward, winding the cord t, connected with the drum, 8, on his right, and turning the arm 8, and the forward wheel H, to the right; the cord 6 being also wound on the drum by the same movement, actuates the lever P, and opens the clutch 2), when the wheel 0 becomes loose on the axle and there is no friction in turning the vehicle. After making the turn, the operator turns the crank 5 forward which unwinds the cord 15 from the drum, releasing the lever P, when the clutch o is immediately closed by a springw on the axle a.

Fig. 5 illustrates in section the bearing boxes I) of the rear axle 0., which said boxes may be secured to a cross-bar b of the main frame, and in Fig. 0 is shown, in longitudinal section, the hub of the forward wheel H on its axle w, theshell of the hub being indicated by y. The hub of said wheel I-I contains a bearing box for its axle w, and the bearing box of axle w and those of axle a are allsub-' stantially similar in construction. Each of said bearing boxes is provided with inner end plates 11 and outer plates 1 the latter being fast on the axle. A circle of rollers z are loosely placed against and around the axle,'

and surrounding the rollers z is a rim 2." which is also loose. Around the rim 2 and between said rim and the shell 1 is another circle of loose rollers .2 Ball bearings a are placed in annular grooves, between the shell y. and the end plates 31', and similar bearings are provided between the inner end plates 1 and the outer end plates 11*.

the main driving power, but additional power I oo is furnished by using the pedals, the crankshafts and sprocket wheels, and the weight of the rider by an occasional movement of his body; and such additional force is of considerable utility in going up a steep ascent, &c. The rider, by the use of thelever E, winds the compressing cord on the drum D when going along on a level or a downward incline.
