H. E. WOERNLE METHOD OF MAKING CHAIN BOLTS Filed March 10, 3 923 FEGJ INVENTOR and M) Patented Nov.
UNITED sr'rss HARRY E. WQERNLE, OF PITTSBURGH, 1?
ENNSYLVANIA, ASSIGNOB/ TO MCKINNEY MANUFACTURING COMPANY. OF EI'ITSBURGH PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
, Application filed March 1923 To all whom it may concern:
Be it known that I, I'IARRY E. lVoinnNLn, a citizen of the lnited States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Methods of liflaking Chain Bolts; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to bolts, and more particularly to a method of making, chainbolts such as are withdrawn by pulling, on a chain, a spring being provided to return the bolt to normal position.
The object of my invention is to form a bolt of this character from a single piece oi? wrought metal which is strong and durable, and which, by the simplicity of its manufacture, enables it to be produced at a minimum cost.
In the accompanying drawing, Fig. 'l is a side elevation of my improved bolt, the bolt proper and the spring being shown. in dotted lines; Fig. 2 is a front view partly in section; Fig. 3 is a front view of the bolt removed; Fig. is a side view; Fig. 5 is a rear View; Fig. 6 is a bottom plan view of the bolt casin and Figs. 7 and 8 are plan and edge views, respectively, of the blank from which the bolt proper is formed.
llhe blank 2, which may be formed from a. sheet 0] steel or other suitable metal, has the enlar top-portion 3 V and the shank-portion t extending: down theret'rom. The bolt is forn'ied from this blank by bendin; the upper portion A by means of suitable tools to form the upper tubular portion 5 of the bolt, while the shank-portion t, for a portion of its length, is bent around to form the sen-ii-circular portion 6 with the shoulder 7 at the point where said portions meet.
Below the semi-circular portion 6 the shank-portion lof the blank is bent to form the flat or angular portion 8, a shoulder 9 being consequently formed between said flatportion 8 and the semi-circular portion 6.
The upper end of the blank 2 is convex, as at 10, and when the metal is bent to form the upper tubular portion 5 the upper end of the bolt is formed with the customary rounded or beveled portion 12.
The bolt so formed is inserted in the customary casing 13, which is provided at its METHOD OF MAKING CHAIN BOLTS.
Serial No. 624,155.
lower end. with the slot 14: to receive the flattened lower portion 8 of the bolt. The spring 15 is interposed between the shoul der '7 and the lower end 16 of the casing, said spring: having; the tendency to hold the bolt in locked position.
A clevis 17 is secured to the lower end of the Ilitt portion 8 which projects through the opening 14, and said clevis is connected to said flat portion by the split pin 18. A chain 19 is connected to the clevis 17. The clevis 17 -forms a stop which controls the upward movement of the bolt.
It will be apparent that the bolt may be readily reversed by withdrawing the flat portion 8 from the opening 14 and turning the same, and then reinserting said flat portion in said opening.
By my invention I provide a chain-bolt which is light in weight, and yet has sufiicient rigidity and strength to stand the wear and tear to which it is subjected, while at the same time by being made of one piece of wrought-metal the simplicity of manufacture makes it possible to form the bolt quickly and at the same time at minimum cost.
What I claim is:
1. The method of forming bolts which comprises providing a substantially flat blank having a wide upper portion whose uppern'iost edge is of si'lbstantially arruato term, bending}; said portion to bring the side edges thereof into adjacent position to form a tubular body portion, bending a portion of the blank to semicircular form of less diameter than said body portion, and forming a shank portion below said intermediate portion of angular form in cross section.
2. The method. of forming bolts which comprises providing a substantially flat blank having a wide upper portion, bending said portion to bring the side edges thereof into adjacent position to form a tubular body portion, bending a portion of the blank to semi-circular form of less diameter than said body portion, and forming a shank portion below said intermediate portion of angular form in cross section.
In testimony whereof I, the said HARRY E. WOERNLE, have hereunto set my hand.
HARRY E. WOERNLE.
