ATTORNEY um'rsn STATES PATENT OFFICE.
Jon W, OI 1m mum, m You may concern:
Be it known that I JOHN McLacnLax, a citizen f the United sees raiding e East Elmhurst,'in the county of Queens and State of New York, have invented certain Improvements in Cam-Shaft Removers, of which the following is-a specification.
This invention, relates to devices for removing shafts which are contained within a housing, and more particularly to devices for removing cam-shafts of automobile engines When it was desired to remove a camshaft from its bearings for the purpose of rep or replacing said shaft or any of its associated components, it has been customary in the past to resort to laborious and time-cons I i 1 operations. Various implements have employed in such opera- .expeditions manner. Other andi tiona view taken on the tions, but it has been fouild that these often cause serious results, -su as strip ing or otherwise injuring the threads of e cam-- I shaft, cracking the crank-case and other im-' pairme'nts too numerous to mention. Ac-
cordingly, it is one of the principal 'ects of this invention to will remove eam-sha rovide a device w 'ch or the like from their hearings in a manner which will eliminate any degree of dam to the shafts or amociated parts. Ano er object consists in carrying out such operation in a sim le 01' jects of the invention will hereinafter ap- In the annexed drawmg,.Figi 1-e 1 is a side elevation of the im roved device, shown part1 in section, and i L 2 is acrom-seceX-X of Fig. 1, looking in the direction of the arrpwa Referring to the drawing, in which like characters represent hke parts throughout, 5 represents a mam body or tubular casing which is preferably composed of steel. Pro-' of thecham vertical line so as to bear flush the lpeatlmflaaelletterahteat. Anlhathl Milly, use. larlal Io. m
sure throizfihout, as will later appear. Connested wi the chamber-portion 7, and-extending'laterally therefrom and longitudinally of the casing is a boredout portion 9 having a smooth surface, which" provides a guideway in which a threaded member or ull-screw 10v may reciprocate. The mem- 10 is of smaller diameter than the guideway 9, and accordingly there is a clearance therebetween. Integral with the member 10, and formed at one end thereof, is ahead 11 which is of tly larger diameter than the member 10 an slidably engages the guideway 9 and is adapted to reciprocate with the member 10 in said guidewiy, thereby cenand guiding the 'ember 10 therein. Th e head i 11 is provid with a bored-out portion 12 ha internal threads formed therein for the end of a cam-shaft.
At the extremity of the threaded member 10 opposite the head 11 is a slot -.18 which is for the purpose ofperm'itting the use of a screw-driver, when- 1t is n to screw the threaded portion 12 on the'end of a cam-shaft. At 14 is indicated the threaded end of a cam-shaft 15, shown as journaled in a 16 and provided with the usual bushing 1 said bearing being mounted within an casing 18. A nut 19 is threaded on 0 member 10 after the head 11 has the end of the cam-shaft and serves d to iihitaamember 10 from the gui ewa as a r a pear.
In the operation of the P the chamber-portion 7 thereo is fitted over the bushing on the cam-shaft so that the circn1arend8lies flush withthecasinglS. The device held by the1 kaurled rtions 6 against sai casing, an 'e p -screw or threaded member 10 is piished forwardly in the gnideway 9 until the threaded portion of chamber 12 the threaded portion on the end of the cam-shaft 16. If any dimculty is experienced in said threaded a screw-driver may be a plied to slot 13 and .p transmitted ereby to the pull-screw-IO. When said members are engaged the'nut 19 is placed on the end of the pull-screw and threaded Patented Nov. 1, 1921.
improved device, I
thereon'untiLit contacts with the end of the'iol casing 5.' At such time, the continued travel of the nut onthe threaded member will resuit in of the circular portion 8' against casing 18 causing the surface of the crank-case with an preson of the pull-screw from the guideway and the removal of the cam-shaft from proportion and minor details of construction, may be resorted to without departi from the spirit or sacrificing any of the a T tering said member insaid provided inthe end of the t for moving said member in the guideway in vantages of the invention. 7 a e What is claimed is: 1. A device for removin cam-shafts, comprising a casing, 31 cham r portion at one end thereof, a guideway connected with the chamber portion and extending laterally therefrom, a threaded member movable in said guideway, a head member integral with the threaded member for iding and centering said member sai guideway and means for reciprocating said threaded member and head member in the guideway.
2. A device for removing cam-shafts, Icomprismg a casing, a chamber portion at one endthereof, a guideway connected with the chamber portion and extending laterally therefrom, a threaded member movable in said uideway, a head member integral with the t readed member for guiding andcenfilrlgeway, a slot 5 tering provided in the endof the threaded member;
ded member July, 1920;
3; A dev1ce for removing cam-shafts,
comprising a casing, a chamber portion at one end thereof, a guideway connected with the chamber portion and extending laterally therefrom, a threaded member movable in said guideway, a head member integral with the threaded member for guiding and censaid member in said guideway, a slot for moving said member in the guideway in one direction, and a nut on said threaded member for moving' said member in theopposite direction. 4. A device for' removing cam-shafts comprising a casing, a chamber portion at one end thereof, a guideway' connected with the chamber portion and extending laterally therefrom, a pull-screw movable in said guideway, a head member integral with the pull-screw for idin and centering the pull-screw in sa1d gui eway, means in said ead member for engaging a cam-shaft, a slot on the pull-screw for moving said means into engagement with the shaft, and a nut threaded onjthe ull-screw for withdrawin said screw from t e ,guideway and said sha from its bearings.
