TOOL FOR REMOVlNG VALVE PARTS.

APPLI CATION FILED 001130. 1917.

Patented ept 3, 1918.

It ll til of convenient length all z-ioiom iii may canoe-27%:

lie it known that Gannon 3 Prices, at citien of the llnited States of i uuerica, residing at ll ashington, District of Columbia, have invented certz'iin new and useful im provoments in Qllools for Removing Valve l'larts of which the following is a specification.

The present invention relates to tools and consists in the combinations and arrangements oi elements hereinafter described and particularly set forth in the accompanying claims.

1: he. invention has for its purpose to pro vide n tool of this character particularly adapted for use on internal combustion engines of the valve-in-the-head-Ltype for removing certain parts of the vaive actua ing mecliianism; and one which may usefully nerve in various other Ways,

Another object of the invention is to produce a tool for the purposes above stated which simple in construction, cheap to produce, and which may he used Without requiring any special skill.

The invention is disclosed hy way of illustration in the accompanying drawing wherein the figure is a perspective view of the tool.

Referring to the construction of the article in further detaih the some consists of a bar l of tool steel, or other suitable metal for handling: and Whose diniensions in cross-section are sutlicicntto Withstand the uses to which the tool would he ordinarily put. The bod) of the bar 1 is of polygonal design in cross-section whereby the surfaces 2 thereof will a'li'ord suitable Workings; faces to be engaged by a Wrench for turning the tool when occasion rel un'es.

lue end of the bar 1 is appreciably flat toned as shaped member n and said hook is disposed at right angles to the body of a bar and h: s for its function to engage with the rocker arm of.the valve to remove the push rod of said valve. in its application the hooked member is placed beneath the rocl er arm and through the leverage ati'orded by the length of thc'bar l sutlicicut tension may be exerted against the spring of said valve arm to easily disconnect the rocker arm from its actuating mcmber.

The opposite end 5 of the bar .[iattcned at 3 and formed to provide a hoolo SIEGNOR D ONE-HALE and tapered extreme end thereof is cated as at 6 to provide the pair of Wedgeshaped members 7 as shown. The function of the two members 7 is to engage with the tensioning spring of the valve, and the space 6 between said men'ibers affords the neces sary clearance for the valve stem In oneration the members 7 are inserted betu een the coils of the spring, and by sullicicnt levof the bar 1 the valve and its cage may be removed.

Another purpose to which the hooked end i of the tool may be put is that for turning a wingomt when the latter is located in an ii'iaccessible place or requiies great strength to he moved. In such an instance the bifurcated end is simply placed in position to engage the Wing members of the uutand a wrench applied to the bar when the bar may he turned as will be understood.

The bar 1. or handle of the tool. is "or polygonal design in crosssection, to the end that the same may be manipulated by the use of a wrench as will be understood. i tlmn'tlle terminating end of the hook portion is at a-point immediately otisetfrom the juncture of the initial hook portion and the handle.

Another purpose to which the members 7 oi the tool may be put is that oi using either or both of said members in the capacity of a screw-driver when the slot to be engaged is of such dimensions that said members 7 may be inserted therein. in this instance also the bar may be turned strmucntality of a Wrench.

it is obvious that those skilled in-the art may vary the details of construction and arraugreuu-nt of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may" be required by the claims.

Having thus fully described my invention. What i claim as new and desire to secure by Letters Patent is:

1. it tool of the character described comprising a handle having one end thereof provided with a hook portion said hook portion being substantially of mi-circular design and dismosed suhstaut ally at right angles to the central h ritudinai axis of said handle, the end of said hook terminatsurfaces and the cut away or hittinon opposed throueh the ining at a point immediately oil'set from the juncture of the initial hook portion and the handle, substantially as set. forth.

2. A tool of the character described comprising a handle of polygonal design in cross-section whereby to be gripped by a manipulating tool, said handle having one end thereof provided with a hook portion substantially oi semi-circular design and disposed at right angles to the central lon- 1 gitudinal axis of said handle, substantially as set forth.

In testimony whereof I affix my signature in the presence of a Witness.
