RLES F. LINCOLN, OF ANDOVER, CON- FOLDING BICYCLE.

SPECIFICATION forming part of Letters Patent No. 518.330, dated April 1?, 1894.

Application filed December 26, 1893. Serial No.4=94;747. (No model.)

To all? whom it may concern.-

Be it known that I, MICHAEL B. RYAN, of Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and useful Improvement in Folding Bicycles, of which the following, taken in connection w1th the accompanying drawings, is a specification.

Like letters of reference indicate corresponding parts.

My present invention relates to bicycles and more especially to a new style in which the frame folds upon itself, and in which a peculiar form of frame is devised giving great strength. Figure 1 is a side elevation of the bicycle 1n usual form for use. Fig. 2 is an elevation representing the article folded. Fig. 3 is a sectional elevation of clasping device on line w, a: of Fig. 1. Fig. 4 is a sectional elevation on l1ne y,y, of Fig. 1. Figs. 5 and 6 are a modification.

The principal object of my present invention 1s to produce a bicycle, so constructed that 1t can be easily folded and thus take up less space in length, when not in use or when transported or stored. This object I attain by means of a novel construction of parts which will be hereinafter explained.

In a device of this character, it is essential that the frame itself should not be weakened and the several parts must be fully secured byeaslly and quickly adjusting locking mecharusm. All of these requisites I have provided. The general style, wheels, pedals and runn ng parts are of the ordinary pattern in use; indeed, my improvements are easily applied to all the ordinary bicycles in market.

It is unnecessary to explain the ordinary parts. I will therefore confine my explanation more especially to the special improvements to which my present invention particularly relates.

Referring to the drawings, the frame proper consists of the front standard A. the bar B. the back standards 0. and D.with the braces E. and F. The connecting bars or rods G. and H. are peculiar to the folding mechan- 13m. The brace E. being secured at its lower end with standard D. rises in an angle of sufficient degree to give a strong longitudinal interlocked, and the opposite end of a. overlapping rod H. similarly. I also preferably form a catch or something of like nature upon the inside of part N. one at the top and the other at the bottom as indicated by b. b. Fig. 3. I also extend the ends of button a. and suitably form each end, so that the ends a. and a of button a. will slide into catch parts I). b. and thus more securely hold the button a. in place, and also more firmly hold the rods G. and H. interlocked. The cam device for securing or interlocking the buttona. is shown in Figs. 1 and 3, and consists of a cam part c. d. and the cam lever 70. The cam part may be formed of two plates, in which case 0. would represent one and d. the other, or they may be formed of one piece the cam part being represented by c. and the wedge part by d. The cam lever k. is formed to overlap or hook over the edge of part (1. as

shown in Fig. 3. When the cam lever is. is thrown up the upper end or hook or catch part slides around the plates and the plates are released or loosened, of course the end of the cam bar or lever will slide around on the part c. and the wedge 01' bevel formed by the part d. will press more or less upon the end of lever according as thelever is shifted. When the lever is pressed down the hook end will follow the bevel of the wedge of part cl. until it reaches its thickest part and by this means will tightly clamp the cam plates and the button a. to which, the cam plates are attached. A rivet g. passes through the button, cam plates and cam' lever into the part N. This form of cam device operates very similarly to the ordinary window catches or fastenings employed to secure the two sashes together. In Fig. 1 the dotted lines indicate the position of the cam lever 70. when thrown up, releasing the button a. and permitting it to be turned so as to release the interlocked bars G. and H.

The cam device may be held in place by a variety of means, and arranged to operate in several well known ways, upon the button. The brace F. is secured to brace E. and extends upward to bar .13. to which it is united. Upon the upper end of brace F. is formed upon it, a sleeve M. said sleeve extending from point indicated by I. to K. Fig. 4, the bottom of sleeve M. resting upon a collar L. attached to or integral with brace F. To the sleeve M. are secured the rods or bars G. H. the opposite ends being secured to standard A. This construction forms an elongated hinge joint by which the two parts of the frame are united. The braces E. and F. may beeach formed of one continuous piece of metal or they may be composed of several pieces joined together in any suitable manner. The essential thing being that they be so formed and placed as to give the requisite stability to the frame structure and aid in supporting a movable folding connection between the different parts of the frame and provide a suitable interlocking device in connection therewith. The mode of folding the bicycle is as follows: Throw up the cam lever h;-turn the button a. quarter round. This releases the bars G and II. and the standard A. and forward Wheel is turned or folded back, the sleeve hinge M. allowing the bars G and H. to be turned carrying standard A. and parts with them. The two portions being brought together can be secured by a simple catch, lock or similar device. To reverse the operation it is only necessary to bring the bars G and H. forward against the support N. fitted to receive the said bars and which forms the upper end of brace E. Then turn the button Ct. its ends entering the catch device attached to part N. therefor and indicated by b. b., and finally tightening cam 70. by turning the cam lever h. downward to its proper position. The cam devices will bring the button a. tightly upon the bars G and II. The several parts will thus be securely interlocked, and the whole frame as strong, stiff and secure as if made of one rigid immovable frame.

The operation of folding or unfolding the machine takes but a moment, and the advantages of such a construction are self evident.

I do not confine myself to the precise construction shown and described as it is evident that the details may be varied and still not depart from the spirit of my invention. For instance the brace F. may be shortened so as to merely form a bearing for a hinge joint at or near its junction with brace E. and the upper end of brace F. dispensed with, in this case the rod H. would be bent or inclined to correspond with brace E. and hinged at a point near the lower end of brace F. and rod G. would be hinged directly to bar B. at point I, the two hinges being placed substantially in a line one above the other. Such a modi fication I illustrate in Fig. 6. In both instances,I get the principles of my folding device and the longitudinal bracing and frame support hereinbefore mentioned. Aga1n,the folding connection between the standard and back frame, might consist of one rod, 1nstead of the two rods G and H. although this latter construction would not be as serviceable.

I prefer the form illustrated in Fig. l the modification, however, shown in Figs. 9 and 6, (Fig. 5 being a section on line 2, a of Fig. 6,) would be a strong and serviceable construction.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
