Be it known th at I, GEORGE W. MILLER, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented newr and useful Improvement-s in Bailway-Velocipedes, of which the following is a specification.

lily invention has forits object certain iinprovenients in the axle-bearings, the brake, and the operating mechanism of railway-ve- .locipedes In the'drawings, forming a part of this specication, Figure l is a front elevation of arailway-velocipede; Fig. 2, a broken side View, looking from the left of Fig. 1, with wheel A removed, showing its axle in section. Figs. 3 and a show the brake device, the former being a side view of the latter, looking from the left hand, and the latter a top view ofY the former, and a top view of the right-hand side of Fig. l; Fig. 5, a side view of the operating mechanism, looking against the end of the seat-board o, and against the side of the handlever h in Fig. l; Fig. 6, a broken portion of Fig. 5 folded up; and Fig. 7, the same as Fig. 2, showing two pivoted bearingwheels instead of one.

The forward truss, 1' r, of the velocipede-franie [is provided with pendent castings forming rect-angularly-recessed boxes a. a at each end, in which boxes t-he revoluble axle Bis loosely located. IThe recess in these boxes is wider than the diameter of the axle B to a degree that said axle cannot be in frictional contact with only one wall of the recess at a time, Fig. 2-that is, when the device is running forward the axle will bear against one wall, and when the device runs backward the axle will shift over and bear against the oth er wall, thus having the least possible stationary bearing to the track-wheel axle. To these boxes a a bearingwheels c c are pivoted, in a position that their lower periphery cornes a little below the upper side or wall of the rectangular box c. Each of these wheels c has an independent pivot rigidly secured to the box c. In such a construction the points of friction are only three-at the bearing-wheel pivot, where said wheel rests on the track wheel axle, and where said axle comes in contact with one wall of the box a. This makes the device very simple, easy of draft, steady in (No model.)

motion, and greatly facilitates the operation, both in running the velocipede and in the care of-it. If it is needed to support the frame or` truss, a like recessed box a." may be located near the center, secured to the frame, as in Fig. 5. The truss r r, with its burden of frame,

seat, and operating mechanism, is placed detachably on the round revcluble axle B, said axle being received in the rectangular recesses of the boxes c a', as before stated, and the lower periphery` of the bearing-wheels cc resting on the upper side of the axle B.

To prevent danger of the device jumping from the axle, detachable pins or bolts e e are inserted through the side walls of the boxes c a', below the axle, Fig.) 2. By referring to this figure it will be observed that when the velooipede is in motion the loose axle B has only two bearing-points, one against the pivoted wheel c, which thus supports all the burden with an easy friction, and the other against the side wall of the box ci', which steadies the axle, preventing a trembling or wavering motion, so common in roller-bearings. If preferred, two bearing-wheels, c c', Fig. 7, may be employed, in which case the axle B has no stationary bearing-point, `as in Fig. 2, but equal ease in running is attained. To the bar R of the frame, which bar extends rearwardly from the right-hand end of the truss r, is secured a perforated casting, e, in which is pivotally located a brake-bar, y, said .bar extending from a point forward of the axle B, thence rearwardly to the casting e, thence at right angles through said casting to therear side of wheel A, and thence upwardly, terminating in the usual brake-shoe, x, Figs. 3 and 4. An S-shaped spring, S, is secured at one end to bar R, and the other end catches under a projection on the brake-bar 31,-as shown in said Figs. 3 and 4.

In operating the brake, the operator, sitting on sea-tc, bea-rs down on the forward end of bar y, which sets the brake-shoe against the wheel A. l/Vhen the foot is removed, the spring S raises the front end of bar i, which releases the brake. Such a brake device is very conveniently operated,and agreat fri ctional bearing secured against the wheel with but slight movement of the bar y, and requires but little strength of the operator.

To a rear extension of bar R a third wheel IOC) .are held by the elasticity of the bail.

is connected in the manu facture of the device. (Not here shown.)

The velocipede is driven by a gear with which the foot-treadle I? and the hand-lever h are connect-ed by a crankshaft, i. rIhis gear meshes with a gear secured to the revoluble axle B, said gears being shown in dotted lines in Fig. 5, merelyto show their relation with other parts. A rocking bar, n, with open recess e, is detachably placed over and on a rod which pivotally supports the hand-lever 7L, Figs. l and 5. This bar u extends rearwardly and catches under the forward end of the seat-frame f, which forms a stop, holding said bar n in a horizontal position when at rest.

A bail, c, is pivotally connected with the forward end of bar n. Its two downwardlyextending arms are bent in toward each other at the ends and inserted in eyes on the front side ofthe footlever, iu which eyes said ends These ends may thus be sprung out of the eyes when d .desiring to detach the bail and rocking bar n for packing or repairs.

rlhe foot-treadle P is pivotally connected with the lower end of the hand-lever by bars. t t. By means of such a construction of pivotally-eonnected parts they may be folded up, as iu Fig. 6, for storage or The rear ends of bars t thave a senesten -what I claim as new is- 1. In a velocipede, the combination of the brake pivotal casting secured to the frame, the brake-bar extending from the front side of the axle rearwardly, thence atvright angles through said casting, and thence upward, terminating with a brake-shoe, and a spring secured to the frame and catching under the projection of the brake-bar, all substantially as described and shown.

2. The combination of the seat-frame, the hand-lever and foot-treadle, the recessed detachable rocking bar, the pivoted detachablyconnected bail, and the bars having the adjusting pivot-holes connecting the foot-treadle and hand-lever, all constructed and adapted to operate substantially as set forth.
