Application filed January 13, Serial 1T0. 529,528.

Toall whoin it may cbn'cem- E v 5 Be it known that I, JOHN F. D NIKE a citizen of the United States, residing at Adonis, in the county of Polk and Statev of Missouri, have inventednew anduseful Improvementsin valve-springTools, of which the following is a specification.v

'Z'his invention. relatesto tools especially des gned for use n .removmgwalves. from internal combustion-engines andihas for an object the provision of, a tool by means of which .the valve spring maybe compressed to facilitate, thefremoval of thevalve.

Another object of the ,invention; is. provisionof a tool as above set forth,- which is adjustable to permit ofitsuse with valves 1 of different lengths and upon. engines where the invention further. includes thefollow ling. novel features and. details of construction, to be hereinaftermorefully;described,

illustrated in V the accompanying: .1 drawings and pointed out in the appended claims.

In the drawings I Figure 1 is asideeleyation of a tool constructed in accordance with the invention and illustrating its application Whenin use.

Figure 2 is a top plan view of the same.

Figure 3 is an edge View.

Figure 1 is a section on the line 4 4: of Figure 1.

Figure 5 is a view similar to Figure 1 but showing the position of the parts when the valve spring is compressed. 7

Referring to the drawin'gs in detail, wherein like characters of reference denote corresponding parts, the tool which comprises the subject matter of'the present application includes a frame having right angularly disposed members 10 and 11, the' said frame further including an angle piece 12 to which is secured upon opposite sides, plates 13, the latter forming the member 10. The member 12 is of sectional formation one of the said sections being formed by the formed tl eangle piece 12, the said bolt the plates 14;, the; thumb nut 16 serving to hold thesections iii-adjusted position,

; Piyot'a -lly mounted 'u-pionla bolt 19 between replaces.n w a m 2 t id a mbeslot-.517 sis-Ve a. in: the act-16a which-is iconneoting thespaced plates 14:. Theother bolt 15 is carried by the member 12 ajnd ex tends through :a slot 18 provided in each of Iii l'g provided with fspaced openings 21 Wherelend fof thisarm is bifurcated as shown at ,i2 2 for the reception of .the. ste1n.23, of ,a valve 24.

Carried bygthe member 10 of the. frame and positioned between the plates 13 of this member is a valve engaging element 32. This element is adapted for engagement with the valve 24. and is mounted between the plates 13 upon a bolt 33, which bolt. is V removably received within openings 34 so as to adjustably positionthe element 32."

In the use of the invention the .tool is positioned as illustrated in Figure 1. Adownward movement of the outer end of the oper-- ating lever 27 will move the inner end of the arm 20 upward so as to compress the same i i as illustratedin Figure 5 ofth'e drawings,

whereupon the valve may be readily removed.

By adjusting the sections of the'mem- 7 her 11 of the frame, the tool'may be adjust-. ed to valves of different 1engths,'while it may be also adapted for use with different,

types of engines where the-position of the I valves within the cylinder block may vary. The tool is adjusted to the length of the valve through the adjustment of-the member 11, while the element 32 may be moved longitudinally of the member 10 of the 7 frame to properly position the said element for engagement with the valve.

For the purpose of holding the valve springs in compressed position, thereis mounted upon the pivot pin 28, a dog 35, which is adapted for engagement with a series of spaced notches 36 provided in the member '12, Pivot-ally mounted upon the operating lever 27, as shown at 37 is an arm 38 which is connected to the dog 35 by a link 39. A spring llconnecting the arm 38 and the lever 37 serves to normallyforce the dog 35 into engagement with the notches in the member 12. I

"When the valve spring has been compressed by the use of the tool, the dog 35 will engage one of the notches 36 and hold the spring in compressed positionuntil said dog is released by operating the pivoted arm 38.

The invention is susceptible of various changes in its form, proportions and minor details of constructionand the right is herein reserved to make such changes as properly fall within the scope of the append ed claims.

Having described the invention what is claimed is: V V

1. A valve spring tool comprisinga frame including right angularly arranged members, a valve engagingelement carried by one of said members,,a spring engaging arm pivotally mounted upon the other member, an operating lever pivotally securedto the frame and a link connecting the arm and lever. I

2., A valve spring tool comprising a frame including right ,angularly arranged member's, a valve engaging element carried by one of said members, a spring engaging arm pivotally mounted upon the-other member,

the frame and engageable with said arm'and a link connecting the supplemental lever with the operating lever.

" 3. A valve spring tool comprising a frame including right angularly arranged members, one of said members being of sectional formation and including'a pairof spaced plates, meansfor adjustably connecting the spaced plates to the other section of said .4 an. operating lever piv'otally secured to the 1 frame, a link connecting-the arm andlever, a supplemental clever pivotally secured to member, an ,armpivotally and adjustably mounted between the spaced plates, means located at one end of said arm for receiving the valve stem, whereby the arm may engage the valve spring, an operating lever pivotally secured to the'sectional memberof the frame, a link connecting the arm andoperating lever and means adjustably secured to.

one of'said members, a spring engaging arm" pivotally mounted upon the othermember, an operating lever pivotally secured to the frame, a link connectingthe-arm and lever and a latch carried by the operating arm. and

engageable withthe frame for holding the tool in adjusted position.

Intestimony whereof I aflix my signature.
