THOMAS MIDGLEY, OF COLUMBUS, OHIO, ASSIGNOR OF ONE-HALF TO THE COLUMBUS BICYCLE COMPANY, OF SAME PLACE.
CRANK-HANGER FOR BICYCLIES.
SPECIFICATION forming part of Letters IPatent No. 603,149, dated April 26, 1898.
Application filed November 26,1897. Serial No. 659,864. (No model.)
Too/ll whom it may concern.-
Be it known that LTHOMAS MIDGLEY, a citizen of the'United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Crank-Hangers 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.
My invention relates to frames for safetybicycles,has especial reference to crank-hangers for such frames, has for its object the strengthening of the hanger by the use of interohangeable ring-sections; and it consists in certain improvements in construction,which will be fully disclosed in the following specification and claims.
In the accompanying drawings,which form part of this specification, Figure 1 represents a plan view of a blank to form a section to engage one of the rear forksof the frame;
Fig. 2, a like view of a blank to form a section to engage the frame-tubes; Fig. 3, an end view of one of the blanks formed into a section; Fig. 4, a perspective of the reinforcements; Fig. 5, an end view of one of the sections with the semitubular reinforcements applied, the tubing of the frame being omitted; Fig. 6, a vertical section through the lower end of the frame and the crank-hanger; Fig. 7, a top plan View of the several sections assembled upon the tubular reinforcement of the crank-hanger; Fig. 8, a longitudinal section through the forks and the crank-hanger; Fig. 9, a top plan view of one of the sections to engage the forks, and Fig; 10 a like view of one of the sections to engage the frame-tubes.
Reference being had to the drawings and the letters thereon, A and B indicate the frame-tubes, and C and D the rear forks, of a bicycle-frame of anyapproved form of construction, and E the crank-hanger, which is composed ofa tube a, which constitutes a reinforcement and upon which are assembled separate sections 0, d, e, and f.
F indicates the blank from which the end sections 0 d are made, and consists of a strap having a body g, which when the blank is bent into a section forms the ring or body G of the section and, with extensions h h, offset on each side of the blank at t i and k 70, the former allowing space for the tube to rest upon the ring or body of the section adjacent to the flat rectangular tang H of the section, and the latter extending part way across the adjacentpenter section 9 or f.
I indicates the blank from which the center sections 6 and f are madeand is substantially a duplicate of the blank F, except that it is larger and also consists of a strap having a body 1, having extensions m m and offset on one side only at n n, which forms a lateral extension of the flat rectangular tang I of the section and laps over the adjacent center section. a
The sections formed from the blanks are interchangeable-that is, the end sections 0 (1 may be applied to either end and the center sections e f may be applied to either side of the longitudinal center of the reinforcingtube a by simply reversing them.
The blanks are formed by blanking or cutting in dies under a press, and the blanks are then bent in other suitable dies for forming the sections, the whole being done in two operations and the metal being cold. The extensions at the ends of the blanks must be pressed close together to form the tang of the sections.
K K indicate the substantially semitubular reinforces applied to the inner end of the tubes of the frame and between which the tangs of the sections a, d, e, and f are inserted.
The reinforces K K are not full semitubes, as they are each half the thickness of the tang of the section to which they are to be applied, less than a semitube or circle.
The sections 0, d, e, and f are brazed on the tube a, the reinforces K K in the'ends of the tubes of the frames, and the tubes brazed to the crank-hanger in the usualmanner and form a cheap and durable construction.
Having thus fully described my invention, what I claim is- 1. A section for forming a built-up crankhanger for a bicycle composed of a continuous piece of metal having a tubular body and a flat rectangular tang offset or projecting beyond the body on one side.
2. A crank-hanger for bicycles composed of a tubular body or reinforcement and separate sections, each section having a tubular body and a flat rectangular tang overlapping the body of the adjacent section, in combination with semitubular reinforces on each side of the tangs and within the frame-tubes.

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