VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 357,110, dated February 1, 1887.

I Application filed October 4, 1886. Serial No. 215,220, (No model.)

.To 11 whom, it may concern.-

Be it known that we, IRVING A. WESTON and WILLARD A. SMITH, of Syracuse, in the county of Onondaga, in the State of New York,

have invented new and useful Improvements mechanism, for a noiseless and automatic ratchet which-permits the drivers, or one of' them, toturn independently when the machine turns a corner, and to connect the same and transmit motion from the actuating devices when the machine goes ahead, for an adjustable securing device which permits the linkbelt to be adjusted readily, and certain other functions and advantages in the operation of this type of vehicles, as hereinafter explained.

With these ends in view our invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, in ,which' like letters indicate corresponding parts in all the views, Figure 1 is a side view of atricycle of the noiseless automatic clutch.

embodying our improvement, and illustrating the general arrangement of the parts. Fig. 2 is a top plan of the same, showing the diverging side bars connected to the goose-neck and axle-support and the two sets of independentlymoving actuating devices connected to the said side bars, the rear seat being removed and the front-seat supports being in section. Fig. '3 is an end view taken back of the drivers, showing the axle-support, divided axle, and noise.- less automatic clutch. Fig. 4. is a detached detail of the front-seat support. Fig. 5'shows an enlarged section, taken on line as m, Fig. 6, Fig. 6 is an enlarged section of the noiseless automatic clutch takenonline z 2, Fig. 5, showing the an enlarged detached plan of the bifurcated goose-neck, showing the manner of attaching the side bars thereto. Fig. 8 is an enlarged detached detail of the goose-neck, illustrating the improved means for guiding the steeringwheel rectilinearly normally and cushioning the front end of the machine. Fig.9 is asection of the same, taken on line 3 3 Fig. 8. Fig. 10 shows an enlarged detail of the adj usting device for tightening the linlebelt; and Fig. 11 shows a front end view of the same, also enlarged.

A A are the driving-wheels. B is the guidewheel, the drivers being journaled in bearings u a formed in the axle-support s, Fig. 3, said drivers being mounted upon independent or divided axle U U. The guide-wheel B is supported in the yoke-frame B, and the stem of the spindle O is journaled in the guide eyes or sockets a a of the neck E, Fig. 1, the stem 0 turning freely in its support.

The neck E wepreferably construct as illus trated in Figs. 1 and 7, and may be termed a bifurcated goose-neck formed from one piece of metal. To the arms a c of the said neck E we secure the diverging side bars, D D, and upon these side bars we secure the frontseat supports d d, Fig. 2, and the two sets of independently-moving actuating mechanisms, comprising the pedals P P, sprocket-wheels G G, and sprocket-wheels G" G secured to the divided axle, as shown in Fig. 3, and the linkbelts L L, the said side bars, D D, being connected with the axle-supports, as shown at Figs. 1 and 2 aforesaid.

In order to guide the steering'wheel normally in a straight line, we provide a spiral, X, secured to the stem of the steering-wheel yoke, as best shown at Fig. 8 of the drawings, the said spiral being fastened about midway its length to the stem, leaving its free ends bearing upon opposite sides of the neck, as best shown at Fig. 9. Thus the tension-0f the spring is exerted upon each side of the neck equally, which tends to guide the steeringwheel rectilinearly, and at the same time the spiral forms a cushioning device, which enables the steering-wheel and front end of the machine to pass an obstruction and yield readily thereto without jolting the operator.

F is the noiseless automatic clutch, composed IOO of the case or shell f, secured to the hub of the driver A, and the circular disk 9, secured to the axle U. The shell f is circular in shape and is provided on its internal periphery with fluted or parallel serrations f, as shown at Fig. 5. The diskg is provided with curved seats 9 for the dogs H H, and the dogs H H are pivoted in the curved seats, the free end engaging the serrations of the shell or casef. Springs h h are secured to the sides of the dogs H, and bear against the shell or case fwith sufficient pressure to prevent rattling, and stops h, Fig. 5, restrict the movement of the dogs when the wheel to which the clutch is applied moves in a reverse direction.

It will be observed that when power is applied to the wheel carrying the clutch to propel it forward the dogs H engage the serrationsf of the shellf, which is secured to the wheel, locking the wheel securely to the shaft or axle U by means of the dog-carrying disk 9, secured to the axle, and thereby the said driver is propelled forward by the actuating mechanism driven from the pedal, the said dogs H H and their stops It being reversely arranged on opposite sides of the center.

Now when it is desired to turn the machine, simply reversing theaction of the pedals]? per mits the dogs H to slide back to the stops h,thus disengaging from the serrations in f, which lib crates the drivcrA and permits the same to turn independently of the opposite driver and al lowing the machine to turn corners freely, while the stops it prevent the dogs from being thrown too far out ofposition. The springs h on the dogs also serve to keep the dogs in frictional contact with the case or shellf, and when the power is applied to start the machine ahead the dogs H move into engagement with the serrations in f, and thus lock the wheel to the axle, as previously described.

The axle-support s is best shown at Fig. 3, and has the hearings to u for the divided axle, and is connected, as already described, to the neck E, Fig. 1, by bars D.

Where two independent sets of actuating I mechanism are employed, the rear seat S, Fig.

1, is mounted on the axle'support, as shown in Fig. 3. The front seat S is mounted on a frame, (1, constructed as shown in the detached detail, Fig. 4, the seat-support being adjustable vertically.

In order to take up the slack in the linkbelt L L, we connect the forward sprocketwheels, G G, to the supportingframe D, as best shown at Figs. 10 and 11.

The stirrup I, carrying the journal t" of the pedal-crank, is pivoted to the support I at i, said support I being bolted or otherwise secured to the supporting-frame D of the machine. A set-screw, 1*, bearing against the journal-bearing of the pedal-crank and sprocket-whecl, serves to adjust the sprocket-wheel, so as to tighten the link-belt when desired.

The side bars, D D, as will'be observed, are secured at an angle with each other to the goose-neck and axle-support, for the purpose of making a strong and stiff frame with a minimum amount of weight therein. The divergence of the bars has a tendency to greatly strengthen the construction, and the said side bars form a connecting frame or support between the stecring-whcel and drivers, upon which the actuating mechanism is supported, as already stated.

The advantage accruing from the employment oftwo sets ofindependently-moving actuating devices in connection with the divided axle arises from the fact that the machinecan be driven tandem by two operators, and the turns can be readily made by disconnecting one wheel from the use of the automatic clutch without stopping the machine, and it is obvious that the clutch can be applied to both wheels and either of the drivers released at the will of the operator.

Our improved construction of the device for guiding the steering-wheel normally in a straight line is equally applicable to tricycles in which but one set of actuating mechanism is employed, and so, also, is the take-up device for tightening the linkbclt L, and two of the herein-described automatic noiseless clutches may be used in the same tricycle attached to the drivers, as previously described.

The operation of the machine with our invention applied thereto will be readily understood from the foregoing.

The steering-wheel is guided normal] yin a straightline by means ot'the equalizing-spring, and cushioned forward, as explained.

\Vhen driven tandem by two operators, andbut one clutch is used, the machine is turned by backing the pedals connected to that part of the divided axle which carries the clutch.

WVe are aware that clutches having internal racks and spring-pawls have been used in connection with foot-levers for propelling velocipedes; hence we do not broadly claim such devices.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The neck E, for supporting the steeringwheel stem, provided with a guide-eye through which said stem passes, a spiral spring mounted on the stem and secured at about midway its length thereto, and the upper and lower ends of the spring bearing against opposite sides of the neck to guide the steering-wheel normally in a straight line and to cushion it in passing obstructions, substantially as specified.

2. The combination, with the bifurcated neck E, of the diverging side bars, D, connected to the arms a of the neck E at one end and to the axle-support at the other end, and actuating means, substantially as described, secured to the diverging side bars, substantially as and for the purpose set forth.
