VELOCIPED E.

SPECIFICATION forming part of Letters Patent No. 369,860, dated September 131, 1887.

Application filed April 7, 1887. Serial No. 234,029.

To all whom it may concern.-

Be it known that I, DANIEL E. KEMPSTER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in RowingTricycles or Vehicles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to rowing tricycles or vehicles similar to that patented by me September 16, 1884, and numbered 305,198.

My improvements which I now desire to secure are herein fully described, and specially pointed out in the claims.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a top plan view of my rowi'ng-tricycle; Fig. 2, a longitudinal vertical section Q on the line x in Fig. 1; Fig. 3, a perspective view of the tricycle,showing an oarsman in the act of rowing; Fig. 4, a side elevation, partly in section, of the righthand clutch and clutchpulley removed from the driving-wheel; Fig. 5, a vertical longitudinal central section of the right-hand driving-wheel hub, its attached clutch, clutch-pulley, axle, and a portion of the frame; Fig. 6, a rear elevation of the U- shaped frame, sliding seat, and axles with driving-wheel hubs thereon; Fig. 7, a longitudinal vertical section of one of the foot-bar clamps; Fig. 8, a perspective view of one of the pulling handles or slides with its antifrietional roller-bearings and a portion of the propelling-cord attached, also a longitudinal section of one of the hollow screws for adj usting said cord.

Reference being had to the drawings, the frame or body of the machine is composed of the U-shaped axle or portion a, the side bars or portions, a a, the front cross-bar, a and the rearwardly extending and upwardlycurvcd arms a a.

b bare the driving-wheels, the hubs of which have screwed fast on their inner sides the clutches c c. The driving-wheels, with their (No model.)

clutches attached thereon,'are loosely mounted on axles d d, extending out from the frame a, i

and are provided with ball-bearings and means for adjusting the same in the usual manner with this class of vehicle.

e is the steering-wheel, mounted in the forked spindlef, which terminates in a central hearing or steering-head, g, on the cross-bar a. The wheel 6 is provided with a mud-guard, h, attached to the fork, as usual. The cross-bar a hasloosely pivoted on its ends small grooved guide-pulleys is k, and the curved arms cfa of the frame have also loosely pivoted thereon small grooved guide-pulleys 7a In. Parallel rods Z Z extend from the cross-bar a to the curved arms a, and are held rigidly by check-nuts m thereon.

at n are flexible bands or cords of any strong pliable material, preferably wire rope. 0 0 are the grooved clutch-pulleys, mounted loosely on shoulders or hearings on the sides of the clutches fast on the driving-wheel hubs, and are held on said clutches (so as to freely revolve thereon) by the circular plates or flanges 0'0, affixed by screws to the side of the said clutch-pulley.

Within the cam-shaped recesses formed in the clutches c are placed a number of loose balls or rolls, c,which wedge between the clutch and clutch-pulley when said pulley is revolved in one direction, thus locking together the said pulleys and. driving-wheels, and revolving the latter in the proper direction to propel the tricycle forward. As the clutchpulleys are revolved in a reverse direction, they instantly free themselves from engage ments, so as to permit the clutches and their drivingwheels to continue their revolutions in a forward direction. The bottom of the groove in the clutch-pulleys is faced with leather or rubber, 0 which prevents the wire cord from slipping when the power is applied thereto. If preferred, the leather or rubber facing may be dispensed with, and the cord be prevented from slipping by winding it several times around the clutch-pulley, and, if necessary, attach it thereto at a point which would not unwind from off said pulley in the ordimachine, and is adapted to be adjusted and held fast on the frame by the screw-clamps p 19. On said foot-bar are the sandals (1 q, hung so as to swivel thereon, and are provided with the foot-straps q q. On thetoes of said sandals are attached the connecting-rods r r by the ball-and-socket joints r 1". Said rods are made in two parts, so as to telescope together, or be adjusted as to their length, and are held rigidly by the screws r 1. These rods are connected or pivoted to short armsff on the forkf, and thus bya slight pressure of the toe of either foot the fork f is caused to swivel and turn the wheel e, so as to steer the tricycle in any direction desired. 8 s are the spoon brakes, and s the brake-lever, all of which are fast on the brake-shaft 8 extending across the machine.

t t are the pulling-handles on the slides t t. Said slides are provided with anti-frictional bearings or rolls 1 for running on the rods or supports U, and they are also provided with hollow screw P, which, by turning so as to unscrew, forms a means of tightening up the cords n, as they stretch from constant use. One end of said cord passes through said screw, and is prevented from drawing out by a knot or ball affixed on the end thereof, and the opposite end of the said cord is firmly attached to the opposite end of the said slide. Thus it will be seen that the propelling-cords are practically endless, as both ends of the same are attached to the same pulling-handle or its slide, which amounts to the same thing, the said slides being mounted on their respective rods or supporting-ways Z Z, and free to reciprocate thereon. I

As shown in Figs. 1, 2, and 3, the cords n pass from the pulling slide forward down around the guide-pulley k on the front of the machine, thence backward to and once around the clutch-pulley 0, and then still backward to and up around the guide pulley k on the arms of, and then forward to the pulling-slides, where they are adj ustably attached. The movement of these pulling slides back and forth, as in act of rowing, oscillates the clutchpulleys, and thus alternately'locks and releases their clutches, and thereby causes the rotation of the driving-wheels in the direction to propel the tricycle forward.

a is the reciprocating seat, having anti-frictional rollers, and o v are parallel bars forming ways or tracks for said roller-seat, the said bars being supported by the frame a and a spring, 8 over the brake-shaft.

The capability of adjustment of the foot-bar p and connecting-rods r. r adapts the tricycle to the use of any person, no matter what the length of leg, as the machine can be readily adjusted to lit the rider and bring his weight over or near the center of the driving-wheels, where desired to obtain the best result.

The construction of the frame with the two side pieces, a a, rigidlyjoining a front crossbar, as shown in Figs. 1 and 3, makes the frame more adaptable to a fore-and-aft adjustment of the foot-bar, and also adds great strength to the frame for supporting the lateral strain occasioned by the steering wheel turning short curves when the tricycle is traveling at a rapid rate of speed.

The construction of the frame with the rearwardly-extending portions or arms a a is a great advantage, as by so doing I am able to obtain a great length of stroke, as required in rowing, on a comparatively short machine, which adapts it to great speed and to readily turning short curves, the stability of the machine being fully insured by the U-shaped frame bringing the center of gravity below the centers of the driving-wheels, the frame of the tricycles being composed of weldless steel tubing properly bent and brazed together, thereby producing a machine very compact, strong, and light.

The pulling-handles are capable of swiveling as well as reciprocating on their supporting ways or rods Z Z, and-thereby permit said handles to rise and fall, and thus adjust themselves to varying positions of the hands, as required for different parts of the stroke. Furthermore, said pullinghandles being entirely independent of each other permits their use alternately, as in canoe practice, and also facilitates the turning of the tricycle, as one handle may be pulled stronger than the other, and thus assist in turning the machine.

I do notwish to confine myself to the use of only three wheels on my machine, as my improvements are equally applicable to vehicles having four or more wheels, and I now contemplate the construction of vehicles embodying my inventions capable of carrying two, three, or four riders or rowers, and the special features of their construction will form the subject-matter of future applications for Letters Patent.
