'N. E. PARISH.
MECHANISM FOR MAKING BICYCLE CRANK HANGERS.
.No'. 588,804.- Patented Aug. 24,1897.
UNITED STATES PATENT OFFICE.
NEFF E. PARISH, OF CLEVELAND, OHIO, ASSIGNOR TO THE PARISH & BINGHAM COMPANY, OF SAME PLACE.
MECHANISM FOR'MAKING BICYCLE-CRANK HANGERS.
SPECIFICATION forming part of LettersPatent No. 588,804, dated August 24, 1897.
Application filed June 29, 1896.
T on whom it may concern:
Be it known that I, NEFF E. PARISH, a citizen of the United States,and a resident of Cleveland, county of. Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Mechanism for Making Bicycle-Crank Hangers, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.
The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.
The object of my invention is to provide a cheap, light, and strong bicycle-crank hanger. I accomplish this object by pressing from a tubular blank closed. bosses to which the members of a bicycle-frame may be attached.
Figure I represents a vertical cross-sectional view of the die-holder, die, and blank; Fig. II, a horizontal cross-sectional view of the die and blank; Fig. III, a perspective view of the completed hanger, and Fig. IV a perspective of the interior of the die.
The die-block A is threaded atthe bottom to receive the base-cap B and at thetop to receive the guide-cap C and is formed with a central bore to receive the circular die D. The die D is made in four sections 01 and is formed with a cylindrical bore. 7 Indentations d, conforming to the bosses on the hanger, are formed upon the inside of the die.
The guide-cap C is bored and tapped to receive the gland c, which is formed with an annular boss 0, similar to and of the same diameter as boss 17. Both of said bosses o and b fit into the bore of the die and are of a diameter such that the blank may be interposed between them and the die D.
The gland c is pierced centrally by the plunger-bore 0 which receives the hydraulically-operated plunger E.
The die-block A having been placed upon a suitable support, the blank F is inserted in the die and the guide-cap C screwed down upon it. Thegland c is then screwed down upon the blank F, which is made sufficiently long to slightly project above the top of the die Serial No. 597,427. (No model.) I
D. The conical bosses Z) and c then enter the bore of the blank and wedge it firmly against the sides of the die. The blank is then filled with oil, beeswax, or other suitable liquid or plastic material. The plunger is then forced into the wax, which communicates the pressure to the inside of the blank, pressing the metal outwardly into the indentations and forming the bosses f. By withdrawing the plunger and removing the guide-cap the die can be withdrawn from the die-holder and the hanger removed from the die by separating said die into its several parts.
The bosses formed in this manner are closed and of great rigidity and stiffness, making the Whole structure of the hanger one of great durability and strength, and are made with a minimum .amount of metal, no waste of metal being involved in the operation.
Other modes of applying the principle of set forth in the following claim are employed.
I therefore particularly point out and distinctly claim as my invention In apparatus for drawing bicycle-hangers from metal tubing, the combination with a separable die, of a die-holder consisting of an integral block formed with a central bore adapted to be fitted by said die, and provided with an upper and a lower cap of larger diameter than said bore, each cap having screwthreaded engagement with said holder, the one cap provided with a blank clamping means adapted to form a gland for a hydraulic plunger, said clamping means provided around its central bore with a conical annu lar boss the outside diameter of whose larger base is less than the inside diameter of the die, the other cap provided with a similar 5 boss, both said bosses adapted to enter the blank and clamp it against said die, substantially as set forth.
In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 24th day of June, A. D 1896.
NEFF E. PARISH.
.Witnesses:
A. E. MERKEL, DAVID B. DAVIES.
