Description

Jan. 22, 1957 n ventor A ttorn e vs United States Patent() APPARATUS FOR FACILITATING THE ADJUST- MENT OF VALVE STEMS OF INTERNAL COM- BUSTION ENGINE FOR TAPPET CLEARANCE Evan Meirion Arthur, West Heath, Birmingham, England Application January 5, 1954, Serial No, 402,315 1 Claim. (Cl. 33181) This invention relates to means for facilitating the grinding in of valves and consequent required adjustof the valve stem for tappet clearance in connection port 1.1
and two upstanding sheet Patented Jan. 22, 1957 by a feeler gauge withon the engine to make correct adjustment. The jig comprises a sheet metal members to form a foot supmetal webs 12 from spot welded together which end lugs 13 project upwardly from each of the posed semi-cylindrical walls 13 of each pair and each threaded for receiving a screwed pin. 15
on which the valve stem justment is obtained by Op- 13a are shaped in each lug hole thus formed is screw means of a feeler gauge between the end of the screw pm and the end of the valve stem 'fitted in the jig.
The valve stem can be spun on the cradles to test for straightness.
The final adjustment can be readily checked in position on the engine as the valve with Having th the guide thereon y placed in position for testing.
