FRAME FOR VELOCIPEDES.

SPECIFICATION forming part of Letters Patent No. 562,067, dated June 16, 1896.

Application filed November 7, 1895. Serial No. 568,165. (No model.)

To allai/hom t may concern:

Be it known that I, JAMES S. COPELAND, a citizen of the United States, and a resident of the city and county of Hartford, in the State of Connecticut, have invented certain new and useful Improvements in Frames for Velocipedes, tbc., of which the following1 is a specification, reference being had tothe accompanying drawings, forming a part hereof.

This invention relates in general to the construction of frames for velocipedes and the like, which are composed of tubes or other members and tubular bodies, and more especially to the means for securing one tube or member to the frame or structure at its end to the side of another tube or tubular body which is disposed transversely to the first tube or frame-brace-such, for example, as the main standard and the crank shaft bracket of a bicycle-frame. Owing to the severe strains to which bicycle and other like frames are subjected it is necessary that such joints be very strong and that weakening of the parts to be connected be avoided as far as possible. It is also desirable that the use of superfluous material be avoided and that the joint be compact and present a neat appearance.

It is the object of this invention to provide for the construction of a joint which shall answer these requirements, and the means by which this result is secured will be fully described hereinafter with reference to the accompanying drawings, forminga part hereof.

In the drawings, Figure l is a transverse section of a crank-shaftbracket with a socket for the attachment of the main standard secured thereto in accordance with this invention. Fig. 2 is an elevation of the same. Figs. 3, 4, and 5 are detail views of a thimble employed in making the joint. Figs. 6 and 7 are views similar to Figs. l and 2, but showing a portion of the main standard applied to the socket. Fig. 8 is alongitudinal section of a crank-shaft bracket with the socket and a portion of the main standard, showing also an additional feature of construction which may be employed, if desired. Figsl 9 and 10 are det-ail views illustrating more clearly the same feature. Figsll and 12 are respectively a longitudinal section and a side elevation illustrating an application of the invention in a slightly-different form to the joining of a main tube and an obliquely-disposed tube.

As represented in Figs. l, 6, 8, and lO of the drawings, the crank-shaft bracket A or other tube or tubular body to the side of which the standard B or other member of the frame is to be secured has formed therein, at a point corresponding with the desired 6o position of the tube B, a hole a, which is of less diameter than the tube B. A socketpiece C, being a relatively short length of tubing, has one end struck up or otherwise manipulated to form an inwardly-projecting flange c and to iit snugly against the tube A, the aperture left within the flange corresponding substantially with the hole d. A thimble D is formed from a short tube (shown in Fig.

4) of a diameter to ft in the hole a and the 7o aperture of the flange c by striking up or spreading the end, as at d. The thimble is inserted in the hole a and the aperture of the flange c of the socket-piece C, preferably from within the tube A, and its other end is upset, as at d', to secure the socket-piece C firmly to the tube A. The tube B, which has its end formed to fit against the tube A and is of a diameter to fit snugly within or upon the socket-piece C, is then slipped into place 8o ,and all of the parts are thereafter more firmly united by brazing or other similar means.

It is obvious that if desired the tube B may be made to fit either upon or within the socket-piece C, and accordingly the term socket-piece is herein used whether the part referred to receives the part B upon or Within itself. It willalso be observed that the socket-piece affords a substantial support for the tube or other frame member B, 9o and that by the described device it is held rigidly and strongly to the tube A, whereby the joint between the tube or otherframe member B and the tube Ais even less liable to be broken than when the socket-piece is integral with the tube A, although the amount of material is less and the cost of construction is much less.

If desired, the end of the tube B may be provided with tongues b l) to enter holes a a 10o in the tube A and to be upset, as clearly represented in Figs. S, 9, and l0, to thereby more firmly secure Athe rtube B to the-tuberi. This, however, vis ari-additional feature' and is not essential to the proper carrying out of the invention, as hereinbefore described.

In the construction represented in Figs. 11 and 12 theinain tube Af has formed therein a hole a2 of such size and shapeas to admit the end of the tube or member B Which isto be secured thereto. Vithin the tube A' is placed a tubular bushing E, which has a hole e of less diameter than the tube' B'. The socket-piece C', as before, is formed with an inwardly-turned i'lange c', Whichts snugly against the tubular body or bushing E, the aperture left Within the iiange corresponding substantially with the hole a. The thirnble D', substantially as before,is crimpedover both the edge of :ther hole ini ithe `bushing E and the` iiange of the socket-piece C. ,"All of the. parts arerf iirmly Junited' by brazing'` or `other similar` means.

Although I have herein i shown and described my invention asapplied to the join-1 ing of the parts of a velocipede-fra1ne,it will beiunderstood jth'atitfis not limited tot Athat or `to any particular use,- but may be ein-4 ployed wherever one member.- of a frame Yor structure isito be secured at its extremity to a tube or tubular body.
