Application filed September 8, 1914. Serial No. 860,543.
Valve-Pick-Up Tools; arid I 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.
My invention has for its object to provide an extremely simple and efiicient pick-up tool, especially adapted for use in picking pp valves having only a slot in their exposed aces.
To the above end, generally stated, the invention consists of the novel construction and arrangement of parts hereinafter de scribed and defined in the claim.
In the accompanying drawings, which illustrate the invention, like characters in-,
dicate like parts, throughout the several views.
Referring to the drawings, F igure 1 is a view, principally in section showing the intake port and intake valve of an explosive engine, and also showing in side elevation the improved pick-up tool applied to the said valve; Fig. 2 is a plan view of the exposed face of the intake valve; Fig. 3 is an edge elevation of the improved pick-up tool; Fig. 4 is a detail view, on an enlarged scale, showing the free ends of the legs of the pick-up tool in normal positions; and Fig. 5 is a view corresponding to Fig. 4, but showing the legs as they will appear when sprung toward each other.
The numeral 1 indicates the intake port of an explosive engine, and the numeral 2 indicates a normally closed opening in the engine casing, leading to said port. Said opening is axially alined with the seat of the intake valve 3 and the said valve may be inserted onto or removed from its seat therethrough. In the exposed face of the valve 3, which may be of the puppet or any desired type, is formed the customary slot 4, into which a screw driver or like tool may be inserted to oscillate the valve when grinding it to its seat. It is usually a very difficult matter to pick up such valves in removing the same from their seats. The improved pick-up tool provided for this pur-' pose 1s made from a single piece of relatively thin, flat spring metal. This piece. of
metal is' bent upon itself to form an intermediate loop 5 and outwardly bowed legs 6, the free ends of which are slightly and reversely curved at 7 and normally in contact at their extremities, adapting the same to be spread when said legs are sprung toward each other. This position of the legs is shown in Fig. 5.
To pick up the valve 3 and remove the same from its seat through the opening 2 the pick-up tool, in its normal position, as shown in Figs. 3 and 4, is inserted through the opening 2 and its lower extremities inserted into the slot 4 of said valve. In this position of the tool the same is held in the hand Z, as indicated in Fig. 1, and by pressing on the legs of said tool to spring the same together, the lower extremities thereof are spread or expanded in a manner previously described. This expansion of the lower extremities of the legs 6 will cause the same to frictionally engage the opposite faces of the slot 4 and thereby very tightly grip the valve 3. When the valve is thus gripped by the pick-up tool, the same may .be easily lifted from its seat and removedthrough the opening 2. If desired, the
outer faces of the lower extremities of the legs 6 may be knurled or roughened at 7, as shown in Fig. 1, to afford better gripping surfaces.
What I claim is:
A pick-up tool made from a single piece of flat spring metal bent to form outwardly bowed legs, the free ends of which have slight reverse curves. that are normally in direct contact at their extremities, and which legs, when sprung toward each other, cause the said slightly reversed curved end portions to shift their point of contact inward from the extremities of said legs with the resulting separation of the said extremities.
In testimony whereof I affix my signatur in presence of two witnesses.
GEORGE H. HAMMOND.
