This invention relates to an improved' tool adapted more particularly for use byV automobile mechanics in removing and replacing valve spring pins, washers, and the like.

Briefly, the improved tool comprises a pair of pivotally connected members provided at their outer ends with pin engaging' jaws and at their opposite ends with spring pressed handles. ln addition, a spring returned device is associated with said menibers and is adapted to facilitate removal and v insertion of said pin.

One feature of construction is the formation of the pivotally connected jaw carrying members of sheet metal, making this p art of the tool exceptionally simple and inexpensive to manufacture.

`Another feature of the invention is the specific construction ofthe plunger-like de-` vice which is employed in association with the sheet. metal members, this devicebeing operable by a lever which mounted on said sheet metal members.

Other features and advantages of the invention will becomeapparent lowing description and drawings. i In the accompanying drawings forming a part of this application and in which like numerals are employed vto designate like parts throughout the same:

Figure l is afsideyiew of a'tool constructed in accordance with the invention.

Figure 2 is a longitudinal section through the major lportionl thereof with certain of the details shown in elevation.

Fi ure 3 is across section taken approximate y upon the plane 'of the line 3 3 of Figure 1. 1

Figure 4 is a top plan View of the structure seen in Figure 1.

Figure 5 is a detail view of the jaws showing how theyniay be engaged witha valve pin. l

Figure 6 is a perspective view of a coupling device between the plunger-like part and the operating lever. Figure 7 is a detail view of 'the jaw equipped end of the toolshowing the inanner in which it may be used forv removing and inserting a washer.. l

In the drawings, the reference character 1 designates one part and 2 the complemental part of the'jaw carrying member. The part 1 is of the.4 channel shaped cross section shown in Figure 3. Moreover, the part 2 is is pivotally from the fol-- what may 'be conveniently designated as arms 3. The outer ends of these arms are provided with longitudinallybowed Lportions 4 terminating in pin gripping jaws 5. The opposite ends of the parts l and 2 are formulated into appropriate handles 6 which are provided at their free ends with inturned extensions 7 fitting into tlie'opposite ends of a coiled spring 8. A pivot and connecting-pin 9 passes through the portion formingthe juncture between the arms 3 and the handles 6. It is yet to be pointed out that as shown in Figure 3, ears or lugs 10 are stamped inwardly from the side walls of the part 2 to provide stops which serve a purpose to be hereinafter described.

Considering now the plunger-like device which cooperates with the'p'arts 1 and 2, this will be more clear by referring tol Figure 2. In this figure, it will be seen that the device comprises a cross head 11, through the central portion of which one end of a coiled spring 12. is connected. The opposite end elongated strips of metal 1.3 are in turn connected to the end portions of the cross lhead 11 and extend forwardly through the channel portions of the arms 3, and terminate in' close spaced proximity to the aforesaid vjaws '5. It will be noted however that the strips are bent atright angles as indicated at 14 and `terminate in spaced parallel extensions 15 whichare in alignment with the aforesaid jaws 5'. Moreover, the central portions of the strips 13 are'provided with inbent portions 16 having openings through which are inserted hooks 17 formed on U-shaped member `18 which is locatedI between the metal strips 13. A linkof appropriate design 19 -is connected to the bight portion of the U-shaped member 18 and has an eye at its outer end which is in tiirn connected to a cross pin 20 carried by the central portion of a lever 21, disposed'on oneside o f the tool and pi-votally mounted 'as In practice it will be seen that the' coil spring 8 which is of the expansion type,

tends to maintain the aforesaid jaws 5 in close spaced gripping relation. Hence, by engaging these jaws .5 with the projecting l\ l l v l mil a substantially d in; an opening in the valve stem, 1t will be easy n an obvious tuck,'and ca ly so that a porti the jaws 5 asv in ger like device w tracted position may and the ends enga in 23-as there shown. T ever 21 about its pivot, the vice can be move pin out' while res valve stem. However, vice is more particular when inserting the pin in be withdrawn-slig tf the end projects into 'd in Figure 5, the hich is there shown in be moved upwarded with the valve en byl pushing the plunger like detion to pull the -against the er like dely adapted for use the valve stem this end it will be seen that ll be forced betweenan d the end portion 1 ll be engage will be rocked to he jaws 5, leaving slightly. Then ligned with the lunger device in into the opening, t to accomplish this ld also direct device can be sher 24 in place (see d in a direc ting the jaws like device wi 'Ihen the lever 21 pull the pin one end portion this projecting en valve stem openin released tofforce t e c thus making it otherwise ditieu attention to the fact used for placing 'a wa in between t d can be a lt task.

bodiment of the 1nd described, it is t minor changes co d of invention' claimed may the same is used. description is While the referred ein vention has een sh to be understo within the fiel resorted te if desired the aforesaid members,

arms of which are con-v I a pull link, a lever i invention, what I 'claim as new an re to secure by Letters Patent is:

1.In -a tool of pivotally conn arms having j aws of the `class described, a `Ipair ected handles provi formed at their outer ends,

la plunger-like device including gripping elements associated with said jaws, and a pivotally mounted operating lever connected with said plunger like in onedirection.

2. In a tool of of sheet metal parts shaped formation, said parts includingopposedspaced handles and arms, said arms being disposed in telescoping relation, being pivotally connected together, and being lprovided at their outer ends with strap-like erL tensions which are longitudinally bowed and terminate in pin gripping jaws, and spring means interposed between the free ends of said handles.

3. In a tool structure 'of the class dethe class described, a pair scribed, a pair of pivotally connected jaw equipped members, and a plunger-like device associated therewith, said deviceI com rising a cross head, a pair of spaced paralle strips connected at one end to the cross head and stamped Vinto channel device for moving it provided at theirbther ends with gripping elements, spring cross head and adapted to be connected with one of the tirst named members, and manually operated v means for actuating ,said

means connected with said 4. In a tool structure of the class described,

a pair ot pivotally connected handle memterminating in pin4 gripanda plunger like device associping jaws,

said handle members, said device ated with comprising a pair of spaced parallel metal strips provided at one end with gripping ele-.

ments, 'a cross head extending between and connected with the opposite "ends of said' strips, acoil sprin connected with the intermediate portiono the crosshead and adapted to 'be connected at its opposite en d vwith a substantially U- shaped member, the nected with said strip, pivotally mounted on one of the aforesaid handle members, and a connection between said link and the intermediate 'portion of said lever.-

In testimonyl whereof I aix my signature.
