To all whom it may concern:

Be it known that I. ARTHUR O. FEILBACH, a citizen of the United States, residingat North Milwaukee, iii the county of Milwaiikee and State of lVisconsin, have invented new and useful Improvements .inv

Tools for Lifting Valve-Springs, of which the following is a specification.

This invention relates to a novel construction of tool, more particularly adapted for lifting automobile valve springs for the purpose of removing the pinsv or holding means for the valves.

The principal object of the invention is to provide means for lioldino` the spring in raised position so both hancs may be used for withdrawing the pin.-

Another object of the invention is to make the device adjustable, so it may be used on different makes and sizes of automobiles.

The invention also consists incertain other features of construction and'in the combi-nation and arrangement of the several parts, to be hereinafter fully described,I

illustrated in the` accompanying drawings and specifically pointedv out in the appended claims. v.

In describing my invention in detail,

i reference will be hadto the accompanying drawings wherein like characters denote like and corresponding parts throughout the several views, and in which:

Figure 1 is a View showing the tool'in Fig. 5 1s a view showing `,another arrangement of the parts.

Fig. 6 is a sectional detail of the socketed member.` e

In these views,- 1 indicates the head Vof the tool which is provided with -an extension 2 having a plurality of screw threaded holes 3 in its outer part. 4 indicates a screw threaded rod having its lower end pointed and its upper endbent at right angle to provide a handle 5. This rod is to engage nut 6 is ada ted to lock said rod in adjusted position in the holes. The head 1 is provided with a large bore 7 and a small bore 8, these bores passing through the-head at right angles to the extension 2. The spring engagging member consists ef. a rod 9 passingsp'eciiiation of Letters Patent. Patented Jan. 13, 1926. Appiication sied January 27, 1919. semi in). 273,372.

through the bore 7 and having its lower end bent at right angles. This bent end is provided with a hole not shown. The bent end is engaged by the fsocketed stein 11 of the forked member 12. This stem is provided withl a plurality of holes 13 to receive, a pin 14: which passes through any oneof the holes 13 into the hole in tlie'bent end of the rod 9, whereby t-lie fork member may be adjusted on the rod 9. The forkedend 12k is of circular foi-mation and itsy upper face is recessed as at 15 -to 'form a seat for the' springcup of the valve stem. A block .16 is adjustably secured to the rod 9 by means of the bolt 17. This block forms a Seat -for a coil spring 18 carried by the rod 9 andl having its other end bearing against the `lower end of the head. In thisrway the spring tends 'to force the fork member, and the extension 2 of thevhead apart. The block 16 carries a small rod 19, the upper end of which engages the small bore 8 in I the head and acts as a guide for the rod 9 o and prevents turning movement of said rod. 20 indicates a hand lever having its lower end forked and pivoted Vby a p in 21 to the head Beyond the pivotal point the forked ends extend at an angle to the handle and 'i these ends are connected with the block 16 by the links 22.

It will thus be seen that: 'when the handle is depressed into the position shown in Fig. 2, the block 16 and the rod 9 will be moved upwardly so as to compress the sprin 18 andY the parts will be held in this position due to` the inclination ofthe forked ends of the handle.

As shown in Fig. 1, the device is placed in position on the ,motor with the pointedend ofthe rod 4engaging the' upper faceof the valve land the fork 12 `is placed' under the spring cup on the ,valve stem. The

handle 20 is then depressed so as to raise the'.

rod 9 and this action will compress the Valve f spring and raise the cup thereof above the pin in the stem. As the parts will be held in .,'this position it will be seen that both hands of the mechanic may be used for withdraw'f ing the pin.

forked member on the bent end of the rod 9- and by placing the rod Il in the proper hole' in the extension' 2. This rod `2 is adjusted in the hole, so asto bring' the parte 4into 1051 As before stated. the tool may be adjusted to fit motors of-diferent sizes by moving the.

be replaced by one of a dierent size to accommodate different sizes of motors.

Inpcases where the'links 22 and the block 16 would come in contact with parts of themotor and thus be prevented from moving, I place said block above the head with the links extending downwardly to the head, as shown in Fig. 5. In this case'the spring 18 is omitted and the parts are returned to normal position by hand.

It is thought from the foregoing description that the advantages and novel features .of my invention will be readily apparent.

I desire it to be understood thatl may make changes in the constructionv and in the combination and arrangement of the several parts, provided that such changes fall withl .in the'scope of the appended claims.

ing the spring cup, a block connected With the last 'mentioned rod, a lever pivoted to the head and links connecting the same with the block.

3. A tool of the class described, comprising a head, an extension thereon, having a plurality of screw threaded holes therein,

a. screw threaded rod adapted to engage any one of said holes, a spring engaging member consisting of a rod slidingly carried by the head'and having a bent end, means carried by said end for engaging the spring cup, a block adjustably secured to last mentioned rod, a spring on said rod located between the said block and head, a hand lever pivoted to the head and links connecting said lever with the block.

In testimony whereof I affix my signature.

ARTHUR O. FEILBACH.
