TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 381,705, dated April 2%, 1888.

Application filed September 8, 1887. Serial No.2i9,102. (No model.)

To all whom, it 27mg concern.-

Be it known that I, \VILLL-UI LAWLESS, of Ottawa, in the county of La Salle and State of Illinois, have invented a new and Improved l.wo-\Nheele-d Vehicle, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved two-whecled vehicle in which the seat can be conveniently adjusted to suit the driver.

The invention consists of shaft-bars carrying a crossbenin on which is held a spring supporting the outer ends of the scat-bars, which are pivoted at their inner ends on the shattbars.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improvement. Fig. 2 is a plan view of the same. Fig. 3 is an end elevation of the spring-clip, and Fig. 4 is a sectional end elevation of the seat bars on the line a: a: of Fig. 1.

The axle A carries the wheels (not shown in the drawings) in the usual manner, and the inner ends of the shalt-bars B are secured in any suitable manner to said axle A. A crossbeam, (3, connects the two shaftbars with each other a suitable distance in front of the axle A, and on the under side of said cross-beam O is secured a plate, D, which projects rearwardly, and on which is fastened in its middle the spring E, extending upward at its outer ends, on which are pivotally hung the clips F, adapted to engage hooks G, formed on the clips H, secured to the seat-bars I, carrying at their rear ends the seat J which is of suitable shape and size. The spring E holds the seat-bars against the under side of the crossbar when the seat is not occupied, and the said crossbar serves as a stop to limit the upward movement of the seat-bars, thereby preventing the liability of the occupant of the seat from being thrown out in passing over rough and uneven surfaces.

The seat-bars I are held in an inclined position, and are each provided at their front ends with a pivot, K, passing through a vertical slot, L, formed in the bearing L, secured to the under side of each shaft-bar B. On the outer threaded end of each pivot K a nut, K, screws against said bearing L, so as to prevent the pivot K from passing out of the slot L. Each pivot K is fulcrumed in an eyebolt, N, which extends downward and passes through an annular projection, L, formed on the lower end of the bearing L and extending inward. On the lower threaded end of the eycbolt N a nut, 0, screws against the under side of the projection L", so as to hold the pivot Kin any desired position on the bearing L.

()n the under side of each seat-bar I is secured a. curved bar, 1?, and the two curved bars I? are connected with each other by the foot-rests Q, preferably made semicircular in cross-section, as illustrated in Figs. 1 and 2, and serving as a rest for the feet of the driver occupying the seat J.

It will be seen that the spring E forms a fulcrum for the seat-bars I, so that the seat bars and the seat J can be adjusted in any de sired position by adjusting the respective nuts 0 and K on the bolt Nand thepivotK,wliereby the latter is raised or lowered in the slot L of the bearing L, thus elevating or depressing the seat J. It will further be seen that the spring E, supporting the seat-bars I easily and freely, insures easy riding for the driver in the seat J.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. In a two-wheeled vehicle, the combination, with the shaft-bars and a cross-bar connecting the same, of a spring carried by the said cross-bar and having upward] y-proj eeting ends, and seat-bars pivoted to the under side of the shaft-bars, projecting rearwardly under the cross-bar, and pivotall y hung from the ends of the spring, whereby the upward movement of the seat-bars will be limited by the crossbar, substantially as described.

2. In a two-wheeled vehicle, the combina tion, with the shaft-bars and a crossbar con necting the same, of a spring carried by said cross-bar and having upwardly-projecting ends, seatbars adjustably and pivotally connected to the shaft-bars, and clips pivoted to ICC the spring and engaging hooks on the shaftsaid cross-beam, in combination with seatbars, substantially as herein shown and debars supported by said spring, a pivot formed scribed. at the end of each seat-bar, a slotted bearing 15 3. In a two-wheeled vehicle, the combinasecured to each shaft-bar and carrying the 5 tion, with the shaft-bars, of a slotted bearing pivot ends of the seat-bars, and an eyebolt secured to each shaft-bar, seat-bars, each havheld on each pivot and passing through the ingapivot onits end held in said slotted bearsaid bearing, substantially as shown and deing, and an eyebolt held on the said pivot scribed.

and bearing for adjusting the said seat-bars, WILLIAM LAYVLESS. I to substantially as shown and described. Witnesses:
