BICYCLE-FRAM E.

SPECIFICATION forming part of Letters Patent No. 617,604, dated January 10, 1899.

Application filed January 12, 1898. Serial No. 666,449. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, JOHN A. REED, a citizen of the United States, residing at Morvin, in the county of Clarke and Stale of Alabama, have invented certain new and useful Improvementsin Bicycle-Frames; andldo hereby 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.

This invention has reference to a novel construction in a bicycle, and it relates more especiali y to the structure of the bicycle-frame, the object being to provide an adjustable frame which can also be taken apart quickly and conveniently, so that it can be packed in a small compass for transportation or otherance with this invention.

and enters the groove 4 in the stem 3.

A further object of the invention is to furnish improved means for adjusting the saddle.

The invention consists in thev features of construction hereinafter described and specically claimed.

In the accompanying drawings,forming part of this specilication, Figure 1 is a side elevation of a bicycle-frame constructed in accord- Fig. 2 is a top plan view. Fig. 3 is a vertical longitudinal section taken on the line 3 3 of Fig. 2. Fig. 4is a horizontal section taken on the line i 4t of Fig. 1.

Referring now to said drawings, 1 indicates the steering-head, and 2 the steering-post. The stem 3 of the handle-bars is straight and extends ini-o the steering-post 2, while on its rear side it is provided with a longitudinal groove el, it being understood that the stem lits snugly within said post. The cap 5 holds the `upper set of balls in place, and it is held in place by a jam-nut 6. A set-screw 7 extends through said cap 5 and through an opening S in the upper end of the steering-post In this way it is seen that the set-screw can be clamped tight to hold the handle-bars in the correct position; but when it is desired to raise the handle-bars the said set-screw can be loosened to allow the stem 3 to move longitudinally, it being obvious that the stem will not turn, owing to the fact that the end of the set-screw 7 is situated within the longitudinal groove 4 therein. The cap 5 is provided with a plurality of screw-threaded openings 9, so that the cap can be turned to compensate for wear and yet permit the set-screw to be inserted.

The frame of the bicycle is similar to what is known as the diamond framethat is to say, it is provided with a top frame 10, the lower frame 11, the backstays 12, the back fork 13, and the diagonal frame 14. These parts are connected together in an adjustable and also separable manner, so that the frame of the bicycle cannot only be adjusted, but the frame can be quickly taken apart and dismembered. There are two top frames or bars 10 and their front ends enter the sockets l5, that project rearwardly from the steeringhead. The front ends of these bars 10 are held within the sockets by means of set-screws 16while the rear ends of the bars 10 extend through openings in a seat-block 17 and are held rigid with relation thereto by the setscrew 18. To the rear ends of the bars 10 are secured coupling-fingers 19,such construction preferably comprising a bifurcated rear end of the bar 10, between which the reduced forward end of the coupling-finger is pivoted.

The backstays 12 are hollow and their upper ends receive the fingers 19, while said stays are provided with set-screws 20 for holding said coupling-fingers in place. Near the rear end of the back fork are the upright projections 21, to the upper ends of which the lower ends of the backstays are pivoted. The crankhanger 22 is provided with rearwardly-extending fingers 23, that enter the forward ends of the sides of the fork 13, the forward ends of the sides of the fork being socketed and provided with set-screws 24: to engage said fingers 23. On the front side of the crank-hanger there is anger 25, that enters the lower socketed end of the lower frame 11 and is held therein by a set-screw 26. The upper end of the lower frame 11 enters the socket 27, projecting rearwardly from the steering-head, and which is also provided with a set-screw 28 to engage the upper end of said lower frame.

The seat-block 17 is provided with the upright l rear side, through which the set-screw 32 evtends, whereby said set-screw serves to hold IOO both the seat-stein no and said socket 3() rigid with relation to said seat-block 17. To the lower end of the socket 30 the diagonal frame 14 is pivoted, the lower end of said 'frame being pivoted to the upper end of an upright projection 34 upon the crank-hanger.

It will he seen from the 'foregoing description that a bicycle-frame constructed in this manner can he readily adjusted, as is obvious, and,further1nore, that it can be quickly taken apart by loosening the several set-screws referred to.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination with the steering-head of a bicycle-frame, the steering-post provided with an opening andthe cap at the upper end of said steering-head provided with a plurality of screw-threaded openings to receive a setscrew, of the Stein of the handle-hars eXtending into said steerin g-post and provided with a longitudinal groove to receive said set-screw.

2. In a bicycle-frame, a steering-head with which the front ends of the top and lower frames are adj nstahly and separably connected, the backstays pivotally, ad j ustahly and scparably connected with the rear end of the top frame and pivoted at their lower ends to the rear end portions of the hack fork, of said back forks ad justably and separably connected at their forward ends with the crankhanger, said crank-hanger being adjustably and separably connected with the lower end of the lower frame, and the diagonal frame pivotally connected at its upper end with the top frame and at its lower end with the crankhanger. v

3. In a sectional bicycle-frame the several parts of which are relatively adjustable, the seat-block adj nstably mounted upon the top frame and provided with an opening, asoeletpiece extending through said opening, a setscrew, and the diagonal frame pivotally connected with the lower end of said socket-piece and pivotall7 connected at its lower end with the crank-hanger.

In testimony whereof I affix my signature in presence of two witnesses. i
