REAR-FORK END FOR BICYCLES.

SPECIFICATION forming part of Letters Patent NO. 587,933, dated August 10, 1897. Application filed March 9, 1897. Serial No. 626 ,646. (No modeL) To all whom it may concern;-

Be it known that I, ROBERT G. CORNFORTH, a citizen of the United States, residing at Seymour, in the county of New Haven and State of Connecticut,have invented certain new and useful Improvements in Rear-Fork Ends for Bicycles; and I do 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. 7

My invention relates to rear-fork ends for bicycles, and has for its object to produce a socket for the adj llS'filDg-SCIGW which shall be I 5 formed by making transverse cuts in the blank and pressing the strip of metal between the cuts in one direction and the strips outside of the cuts in the opposite direction to form loops which comprise the socket.

With this end in View I have devised the novel rear-fork end which I will now describe, referring by reference-characters to the accompanying drawings, forming a part of this specification, in which-- Figure 1 is an elevation, and Fig. 2 an edge view, of so much of a rear-fork end for bicycles as is necessary to illustrate my present invention; and Fig. 3 is a view the reverse of Fig. 1 and showing the adj listing-screw placed 0 centrally of the rear-fork end instead of upon one side, as in Figs. 1 and 2.

A denotes the blank from which my novel rear-fork end is formed. The blank is struck out and formed from sheet metal and com- 3 5 prises a body 1, having a slot 2 to receive one end of the axle and arms 3, the continuations of which (not shown in the drawings) serve as the tube connections. These tube con nections are not shown in this application, as they 0 form no portion of my present invention. I preferably use, however, in connection with my novel adjusting-screw socket the tube connections described and claimed in the pending application of Frank H. Beecher and my self, Serial No. 602,859, filed August 15, 1896.

metal 9 between the cuts in one direction and I pressing the strips 10 outside of the cuts in the opposite direction, thus forming three loops which together comprise the socket, which is threaded to receive the adjustingscrew, the position of the adjustingscrew relatively to the fork end being determined by the position of the loops which comprise the socket. This socket may be formed by pressing either strip 9 or strips 10 outward farther than the other strips. In Figs. 1 and 2 I have shown strip 9 as pressed outward farther than strips 10, so as to place the socket at one side of the rear-fork end, and in Fig.

3 I have shown strips 10 as pressed in one direction the same distance that strip 9 is pressed in the opposite direction, so that the socket is formed approximately at the center of the rear-fork end.

Having thus described my invention, I claim- Arear-fork end for bicycles formed from a blank of sheet metal and having an adjusting-screw socket formed by making transverse cuts in the blank and pressing the strip of metal between the cuts in one direction and the strips outside of the cuts in the opposite direction to form loops which comprise the socket, substantially as shown and described.

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

ROBERT G. CORNFORTH.
