To all1 whom' it 'rmi/yv concern:

Be'it known that I, EDGAR M. WoRDEN,

aic'itile'n of the United States, residing at Ladysmith, county' of Rusk, and State of Wisconsin, have invented a certaininew and useful Tool for Operating Upon Cotter- Pins, of which the following is a specification.

My invention relates to an implement to be used in handling Cotter pins as the same are used in connection With bolts or other operative parts of machinery to key or hold said parts in proper operative position.

A primary object of myinvention is to provide a device having the characteristics of ordinary'pliers vvhieih shall nevertheless be especially adapted tothe work of removing, straightening, and inserting cotter pins from operative. parts of machines, especially automobiles.l

I .-1 further object of my invention is to provide a tool having the characteristics above described which shall be simply constructed and have the parts thereof so arranged as particularly to adapt the tool to the special purpose indicated and at the same time in nowise interfere with its use as a wrench, pliers, or Wire-cutter. Otller'objectsof my invention will appear in connection :with the detailed description thereof :rnd are particularly pointed out in the claim.

' In the drawings, which represent one form of my invention-Figures1,2, and are plan views of my tool showing the same in different opera-tive positions relative to. the Cotter pin. Fig. 4 is a partial plan with the same portions in section. Fig. 5 is a side view. Fig. 6 is an end View. F ig. 7

.is a view from above of the tool as shown unusually wide spread of said jaws and the handles,1 as clearly shown in Fig. 1, for a purpose'to be later; described. Each of the circular centr l portions 4 of my tool is provided with notches 8 WhichI are brought into register when the pincers are partially* opened to be used as wirecutters,.as' clearly.

shown in Fig. 4. Thejaws 5 and 6 are outwardly curved, as shown, and are provided on the interior .thereof with corrugated surfaces 9and.10,respectively, to adapt said jaws to be used as either a pipe wrench or nut wrench. The ends of the jaws are provided vvith pinching surfaces 11 andv 12, re-

spectively, which are formed so as to meet-l inparallel relation when the jaws are closed, as clearlyshown in Fig-3. A

Each of the above features isor'Inayibii` of substantially the character found in tools` of this nature inrcommon use.

My improvements are designed to 'adapt this tool, Without interfering in'` any Way with its other uses, to the special function. of handling cotter pins vused as keys for bolts or other operative parts of machines, particularly in connection with automobiles, in which a large number of parts arekeyed into position by means'of cotter pins, and where the necessity frequently arises of removing said pins for the purpose of eti`ecting adjustment or repair of such parts. It frequently happens that when the cotter -pin has been removed it will be found. Ato be bent or injured in some .way so .that before it can be reinsertcd to key on the partirom which A l prongs 14of said cleft being longer than the other and adapted to insert under the edge of the eye of a Cotter pin to prythe same up suttlciently to begrasped by a pin 15 to be later described or inl another position the head of the Cotter pin may be received Within the cleft 13 and thereby pried up or lifted. To Withdraw the Cotter pin fr'om its seat, I provide the pin 15 yvhich isrigidly extended from the face 12 lof the jaw 6 andiseat's in an opening 16 in the end of the jaw 5, the pin 1'5afnd the opening 16 extending substantiallyat lright angles to the faces 11 and 12 but" being preferably slightly curved, as shovvng. to more` readily permit the insertion andvvithdrawal of the pin 15 from' the hole 16;"When the eye of the cotter pin is suii- For eiently exposed or has been pried up eo ns lio expose. ify by eilher the prong le or the melt' 13, the pin l5 Will he inserted through Said eye I and closed into the hole 1G, when, :P5 will be readily imderS'l'ood, the Coller pin .muy he Withdrawn from ills seul, however slrongly wedged therein or bent or fflefornled may he the condition of said coller pin. lt muy he .noted that the arrangement of die memberl l :1nd 2 so lo `give the Wide spread lo mid members and lhe jaws, when opened, perj jews 5 und 6 with .im extended portion 1T havin@` therenerose tinnsveree Grooves 18 and l), respectively, said grooves .lying in the faeeS of Suid extended portion l? so LhfilV when the jews nre closedy lhe grooves will register one above the other in parallel relie tion thus forming round holee or .seals of slighl'l y leSS diameter than that of thecotter pins usually employed.
