ROBERT ELLIS, OF NIAGARAFALLS, NEW YORK.
SPECIFICATION forming part of Letters Patent No. 712,784, dated November 4, 1902.
Application filed September 1O 1902. Serial No. 122,802. (No model.)
To aZZ whom, it may concern:
Be it known that 1, ROBERT ELLIS, a citizen of the United States, residing at Niagara Falls, in the county of Niagara and State of New York, have invented'certain new and useful Improvements in Bicycle-Frames; and I do declare the followingto 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 of reference marked thereon, which form a part of this specification.
This invention has relation to improve-' ments in bicycles; and it consists in the novel construction andarrangement of the frame, whereby a yielding motion is imparted there-- to, all as will be hereinafter fully explained, and particularly pointed out in the appended claim.
The annexed drawings, to which reference is made, fully illustrate my invention, in which- Figure 1 represents a side view of my device. Fig. 2 is a plan View of the same. Fig. 3 is a detail sectional view of the hub, block; and part of the frame n. Fig. at is a vertical; detail sectional view of the same, and Fig. 5 is a detail of the front portion of the frame v.
Referring by letter to the accompanying drawings, A designates the bicycle-frame, comprising the usual forward brace-bar a, upper bar I) and sleeve c, and vertical seatpost d.
B represents the hub, which isprovided with two rearwardly-pr'ojecting arms e e, having openings or bearings f f in their endsto receive the arms or journals g g, extending from one side of said hub to the other'side" and which passes through an openingh'in' the block 2', thereby pivoting said block'to" the side arms of the hub. The endj of this block is curved, as at'k, correspouding with the exterior of the hub, and at the opposite end of said block is a lug or pin Z, that enters an opening an in the U-shaped skeleton frame n, thus pivoting said frame to said block. At the outer ends 0 0 of the U-shaped frame 11 are provided lug'pp, having openings r 1", through which pins 3 8 pass, which also pass through openingstt in the bifurcated ends to u of a second U-shaped frame 1), thus pivoting the two U-shaped frames to one an other at this point. The forwardeud of this frame 22 is provided with a sleeve 'w, having on each side thereof lugs x 00,- providedwith openingsy y to receive the ends ,2 a of a pair of springs a a, which are pivoted to lu'gsb 1), extending on each side of bar 0, said bar being constructed with a narrow stem (1, that engages the sleeve w, and having the shoulder e andforward end f, that is pivoted to the seat-post in the slot 9.
Thus it will be seen from the above descrip tion, when taken in connection with the accompanying drawings, that by the construc= tion of my device the rear portion of thezbi cycle-frame is yielding and affords elasticity thereto through the medium of the springs aforesaid, and a bicycle constructed as herein described is durable, light, easy-riding, and
at the same time cheap to manufacture.
. What I'claim is i In a bicycle, the frame comprising the bars .a, b, sleeve'c, post 01 and pivoted upper and lower frames o, n the upper frame provided with the sleeve 10', having the-side perforated lugs w, 00, the bar 0, constructed with the re= 'frame, the whole adapted to operate 'substan tially. as "described.
In testimony whereofI affix my signature in presence of two witnesses.
ROBERT ELLIS. Witnesses:
HORACE BLACKBURN, MILDRED JOHNSON.
