Specification of Letters Patent.
Patented April 9, 1907.
Application filed May S, 1906. Serial No. 314,984.
T all whom it may concern:
Be it known that I, IVILLIAM IVA'r'rs SLEE- MAN, a citizen of the United States, residing at Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Connecting- Rod Heads, of which the following is a specific-ation, reference being had therein to the accompanying drawings.
My invention relates to improvements in connecting-rod heads, the construction of .which is herein fully set forth and illustrated by the accompanying drawings, which form a part hereof, and in which- Figure l is a side elevation. Fig. 2 is an end elevation. Fig. 3 is a pers )ective view of the head partially disassembled.
The object of my invention is to provide a connecting-rod head for engines and like mazo ehinery which may be more easily and cheaply machined and assembled than any of the present styles of connecting-rod and at the saine time retain all the desirable features as to strength, appearance, and -finish that any of the present styles of head possess.
My construction is as follows:
The head consists, essentially, of the jaws l, which are rigidly connected at the rear and open at the front end. 'Ihe inner opposing 3o faces 2 2 of said jaws are concave or grooved longitudinally, said grooves preferably being portions of a true circle, so that said jaw may be bored out and finished with a drill or on a lathe, boring-mill, or any like machine-tool.
The upper and lower or opposite faces of the brasses 3 4 are made convex, which faces are also a portion of a true circle to conform to the concavity of the jaws between which they are inserted from the open end.
The forward face of the front brass et is made wedge-shaped in the usual manner, and a wedge 5 of the usual form is provided for adjusting said front brass, the adjustingscrews s s being for this purpose.
The front or openend of the head is closed j by means of the head-block 6, the upper and lower faces of which are convex in conformity to the concavity of the inner faces 2 of the jaws l, In the concave face of each of said jaws, near to the open end, is formed a transverse groove 7 7, which receives the tongue 8, formed upon the periphery of the head-block. Said block 6 is inserted between or removed from said jaws by giving the same a partial rotation or a lateral movement, as shown in Eig. 3, tongues 8 occupying grooves 7.
A bolt 9 is inserted through the jaws and head-block, and when the nut 9 is firmly screwed up the various elements of the head are held firmly together. T he tongue S bears all the strain which is exerted upon the head-block by the action of the wedge 5 or the stress due to power exerted upon` the wristpin. Hence any shear upon the bolt 9 is avoided, the only strain upon said bolt being that of tension due to any tendency of jaws 1 to spread apart.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a connecting-rod head, aws having longitudinally and transversely grooved op- )osing faces, brasses adapted to occupy said longitudinal grooves, the forward face of the front brass being beveled for the purpose set forth, a head-block having rounded ends and a tongue thereon adapted to oceu )y said transverse grooves, said head-bloc being insertible between said jaws by a lateral or rotary movement, means of securing said block in position, a wedge positioned between said brasses and said block, and means for adjusting said wedge.
In testimony whereof I allix my signature in presence of two witnesses.
