WADE H. MCBARNES, OF DECATUR, INDIANA.

VELOCIIPEDE.

To all whom it may concern:

Be it known that I, Mon H. McBannns, a citizen of the United States of America, and resident of Decatur, in the county of Adams and State of Indiana, have invented certain new and useful Improvements in Velocipedes, of which the following is a specification.

This invention relates to velocipedes and particularly to means for propelling the same.

An object of this invention is to provide novel means for propelling and steering the velocipede and while I refer to this invention as applicable to velocipedes, it is to be understood that I mean thereby small wagons, and other vehicles ordinarily propelled by the occupant thereof, regardless of the number of wheels or of the body of the said vehicle.

A further object of this invention is to provide power transmitting mechanism whereby the movement of the arms and legs of the occupants of the vehicle may be communicated to the power or driven shaft, novel means being also provided for permitting the said vehicle to run freely as in coasting without reciprocating the means utilized for communicating the motion of the arm of the occupant of the said velocipede to the driving mechanism.

IVith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote correspond ing parts in the several views, and in which Figure 1 illustrates a view in side elevation of a velocipede embodying the invention, the same being partly in section; Fig. 2 illustrates a sectional View of a fragment of the machine, said section being taken approximately along the longitudinal center thereof; Fig. 3 illustrates a top plan view; Fig. 4. is an enlarged detail sectional view of a modified construction of the sleeve 25; Fig. 5 illustrates a fragmental perspective detail view of a hand brake mechanism; Fig. 6 illustrates a view in elevation partly in section showing a modified construction Specification of Letters Patent.

Application filed February 21, 1911.

Patented Mar. 19, 1912. Serial No. 610,073.

in which gear wheels are used instead of the crank and pitman; Fig. 7 is a side elevation, partly in section, of a modified form of the device; Fig. 8 is a fragmental detail sectional view of the gearing, shown in Fig.

7, and Fig. 9 is a fragmental detail plan view of the gearing, shown in Fig. 8.

In these drawings I have shown a frame for the vclocipede comprising two sills 7 and 8 with connecting bars 9 and 10at the front and rear end respectively, the said sills being spaced apart.

The sills '7 and 8 are formed of angle iron and the sill 7 has a depending flange 7 whereas the sill S has a depending flange 8. the said flanges 7 and 8 being provided with bearings 8", in which a crank shaft 11 is journaled, the said crank shaft being provided with traction wheels 12. One wheel may be secured on the shaft as shown in Fig. 3, whereas the other wheel may be connected to the shaft by the pawl and ratchet mechanism shown in Fig. (3 but I do notwish to be limited with respect to the manner of mounting the wheels on the shaft.

A leaf spring 13 has depending ends 14 provided with bearings for the crank shaft and said leaf spring supports the seat 15 at its rear, the said seat 15 being also supported by a bracket 16 fastened to the sills 7 and 8.

The crank shaft is provided with a pitman 17 and the crank of the shaft is located mcdianly of said shaft so that the crank portion thereof is free to rotate in the space between the sills. The pitman 17 is pro vided with pedals 18 which are adapted to be engaged by the feet of the occupant of the velocipede so that the said pitman may be moved forwardly by pressure on the pedals. A further means for operating the pitman consists of a lever 19 mounted on a pivot 20 extending through the depending flanges of the sills, the said. lever having its upper end bifurcated to form the

arms

21 and 22, to which the links 23 and 24 respectively are pivoted, the said links in turn being pivotally connected to a collar 25 which is mounted on a sleeve 26. The sleeve 26 has a flange 26 on its lower end to limit the movement of the collar 25. The collar 25 has a bolt 27 movable through the aperture 28 of said collar, the said bolt being provided with means 27 for causing it to engage one of the peripheral grooves 29, in

the sleeve 26. By disengaging thebolt from the groove 29, the collar may be reciprocated on the sleeve, but when the bolt is engaged in one of the grooves, said collar is locked against reciprocatory movement on the sleeve.

In the modification shown in Fig. 4, the bolt 28 is shown as a removable member, which is detained in the groove 29 by the cap or cover 27*. The spring 27 wedges the bolt between the cover and the shaft, for preventing rattling of the bolt and cover.

The sleeve 26 has a longitudinally disposed opening, the wall of which is angular in cross section and adapted to fit the actuating shaft 30, which shaft is journaled in the bracket 31 secured to the sills. The sleeve 26 is, therefore, slidable on the shaft so that it moves independently of the shaft when sliding lengthwise thereof and transmits rotary motion to the shaft when the said sleeve is rotated, the latter being pro vided with a hand wheel 32 for the purpose of permitting its manipulation.

The shaft 30 has a beveled gear 33, on one end, which meshes with a gear wheel 3t on a shaft 35 of a forked bearing 36 in which a steering wheel 37 is journaled. By the rotation of the shaft 30 and the consequent rotation of the gear wheels 33 and 3%, the ground wheel 37 is moved for the purpose of steering the velocipede and therefore the said velocipede is under the control of the occupant through the means employed for driving the sail velocipede, and the machine may be simultaneously aropelled and steered by simultaneously rotating and reciprocating the wheel 32 and sleeve 26. As a means for connecting the shaft 35 to the wheels, I aperture the member 9 and. provide a bearing 9 thereon. A bearing member 31, which supports the shaft 30, is secured to a bridge 31, by means of rivets or other fastening means.

The rear axle is provided with a brake band 39 at each end, the said brake band having one of its ends secured to a horizontally disposed portion 10, of a lever 41, which is journaled in the depending end 14: of the flat spring 13. The lever ll has an arm 42 to which an end of the brake band is connected after the said brake band has been caused to embrace the hub of the wheel.

Fig. 5 shows one half of the lever 11 and. itis to be understood that the other half thereof is of a construction similar to that shown and described and as the said lever is shown as continuing across the sills in Fig. 3, it follows that the two ends of the lever may be connected with a friction brake and both actuated by manipulating the middle portion 41 of the lever, which passes over the sills in front of the seat 15. By inspecting Fig. 5, it will be seen that a downward movement of the portion 4:1 will result in causing the arm L2 to draw the brake band against the hub and therefore the degree of movement of the said lever will determine the pressure of the brake band on the hub. The portion i1 is held normally elevated by means of the spring 4L3 which is connected to the said lever and has its opposite end anchored to the seat 15.

The ratchet hub shown in Fig. 6 may be used on both ends of the crank 11, when desired, to permit coasting of the velocipede without communicating motion to the pitman and. pitman actuating mechanism.

Figs. 7, 8 and 9 show the operation of the velocipede by means of gearing which is a slightly modified arrangement as compared with that previously disclosed. In this modified construction, the running gear and the means for controlling the same is in all respects similar to that heretofore described, but instead of connecting the lever to a long pitman, in this last named construction the gear wheel A. is mounted on the rear wheel axle B and a gear wheel C has a crank shaft D, rotatably mounted in the bearings E, E, which are similar to the bearings for the gear wheel. The gear wheel 13 is preferably smaller than the driving gear wheel C and the said driving gear wheel is provided with a crank F to which the pitman G is connected, and the said pitman is pivoted to the lever 19 which is operated in thismodificaticn in the same manner as is the lever 19, described in connect-ion with Figs. 1 and 2.

The gear wheel may be protected by a shield or casing J attached to the sills in any appropriate way.
