VALVE-TOOL.

Specification of Letters Patent.

Patented Oct. 26,- 1920.

Application filed December 29, 1919. Serial No. 347,895.

' To all w 710m it may concern:

Be it known that I, EDWARD W'. Sinne- LnY, a citizen of the United States, residing at New l/Vashington, in the county of Crawford and State of Ohio, have invented new and useful Improvements in Valve- Tools, of which the following is a specification.

This invention relates to improvements in tools for removing the spring of a tappet valve of a gas engine.

The primary object of the invention is to produce an extremely simple, cheap and eifective tool by means of which the spring of the valve can be readily compressed so that the cross key may be removed from the valve stem to permit of the subsequent removal of both the spring and valve.

A further object of the invention is to produce a tool of this character which shall be of such a construction so that the same may be operated upon various sizes and styles of tappet valves.

The drawings illustrate a simple and satisfactory embodiment. of the improvement reduced to practice.

Figure l is a perspective view of the improved tool. r

Fig. 2 is a top plan view thereof.

Fig. 8 is a side elevation showing a valve engaged by the tool, the spring thereof compressed.

Fig. 4 is a greatly enlarged sectional view approximately on the line l-4c ofFig. 3.

lily valve tool includes base 5 formed from a strip of flat material, metal pre ferred. The base 5, at one end thereof is bent at a right angle upon itself providing the front portion G ef the device. The front plate 6 is given a half twist to provide an extension 7 which has a plurality of spaced apertures 8 therethrough.

The handle member of the device is also constructed of a single piece of metal which is centrally bent upon itself to provide inwardly diverging or inclined arms 99. The arms 99 at the ends thereof are provided' with alining openings and through the said openings, as well as through one of the apertures 8 is passed a pivot member 10. The pivot is preferably in the nature of a bolt, the threads thereof being engaged by a nut 11. The diverging arms 99 of the handle 12 permit of the reception therebetween of valve stems 18 of varying crosssectional diameters. In addition to this the lower edges of the said arms engage with various sizes of coiled springs l l that bear against the washer plates 15 carried by the stem. The valve cage 16 rests on the base 5. A pressure of the handle member 12 from the base will compressthe spring 14: to 1 ermit of the removal of the key 17.

By removing the pivot 10, and adjusting the handle on the front of the base the same may be operated upon valves of different lengths as will, it is thought be fully understood.

7 It will of course be understood that after the key is removed the spring is permitted to expand and then is removed entirely from the valve stem. The tool is operated in the same manner when the spring is replaced to permit of the reinsertion of the key through the valve stem, and it is thought that the simplicity and advantages of the construction will be apparent without further detail description.

Having thus described the invention, what I claim is 2- A tool for facilitating the removal of springs of engine tappet valves, including a base having an offset end, and a handle which is adjustably pivoted to said end, said handle being arranged directly over the base and formed from a single piece of metal which is centrally rounded on itself and provided with arms which extend from the said rounded portion at an inclined angle with respect to each other, the ends of the said arms being pivoted to the base, and the handle providing a substantially hollow V-shaped member whereby varying sizes of coiled springs, washer plates and valve stems may be arranged between and in the path of engagement with the arms of the handle.

In testimony whereof I affix my signature.

EDWARD W. SHEIBLEY.
