' T0 all whom t may concern:
j in opposite directionsto provi Be it known that I, DANIEL A'LEFs, a citizen of the United States, residing at Great Bend,in the county of Barton, State of Kansas, have invented certain new and useful Improvements in Valve-Lifters; l'and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to valve .lifters and has for an object to provide an extensible jaw on one of the handle levers of the valve lifter whereby the toolmay be adjusted to fit various sizes of valves.
this character that will be formed of a few simple parts that may be manufactured ata minimum cost and that will not easily get out of order.
With the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.
In the accompanying drawing illustrating this invention, Figure 1 is a sectional view showing the application of the invention, the tool being in elevation. Fig. 2 is a longitudinal sectional view through the tool showing the adjustable jaw in dotted lines in an adjusted position. Fig. 3 is a perspective view of the -tool adj ustable jaw with the cap removed. Fig. 4 is a perspective view of the cap.
Referring now to the drawing in which like charactersV of reference designate similar parts, the tool is shown to comprise a pair of handle levers 10 and 11 crossed near their working ends and pivotally connected together at their crossing by a pivot pin 12, the levers beyond their crossing being curved e jaws 13 and 14 one of which terminates in a forked working end 15 and the other of which terminates in an enlarged externally threaded head 16l upon which is screwed a cap 17.
The forked jaw 15 is adapted to receive the valve stem 18 and engagebeneath the lower end of the valve spring 19 while the cap 17 of the jaw 13 is designed to bear upon y the top of the valve 20 as shown in Fig. 1. When the handle levers are compressed the valve will be held seated by the jaw 13 while the forked jaw 15 will move upwardly and compress the valve ring 19 to permit withdrawal of the usual ey whereupon the valve may be withdrawn for cleaning and repairs.
It is well known that in various types of engines the valves are disposed at various distances below the top of the valve chambers, and it will be seen that the jaw 13 of j this tool is extensible to adapt the tool to be A further object is to provide a tool of applied to valves disposed at various distances below the top of the respective valve chamber. By simply retracting or advancing the cap 17 on the threaded head 16 the jaw 13 may be adjusted as above described and for the purpose above described.
From. the above description it will be seen that I have provided an extremely simpleV and durable valve lifter that will be formed of a few strong and durable parts that will be effective in operation and will not easily get out of orde What is claimed, is A device for compressing valve springs consisting of crossed levers pivoted together DANIEL ALEFs.
