tlhll'lhl) STATES EDWARD W. MENNIE, OF DETROIT, MICHIGAN.
COT'I'EB-PIN EXTRACTOR.
Application filed February 24, 1921. Serial No. 447,563.
To all whom it may concern:
Be it lrnown that l, EDWARD vV. Mnn'mn, a citizen of the Dominion of Canada, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and improved Cotter -Pin l lxtractor, of which the following a specification.
This invention relates to means for pull.- ing out cotter pins which are so positioned as not to be readily accessible, and its object is to provide a tool of this character which can be cheaply constructed which will be strong and e'llicient in operation, and which cannot get out of order.
This invention is embodied in a pair of handles pivoted together, one of the handles having a pointed jaw adapted to enter the eyes of cotter pins, and the other handle having a jaw which serves as a fulcrum member, the two aws being adapted to swing past each other.
It also consists in bending one of the jaws so that its end 18 substantially parallel.
to the axis of the handles.
It further consists in the details oi? construction illustrated in the accompanying drawing and particularly pointed out in the claims.
In the drawing, Fig. l is a side elevation of the preferred form of cotter pin extractor having its pointed jaw engagin a cotter pin. Fi 2 is an elevation of the aws thereof when a cotter pin has beenpractically extracted. Fig. 3 is a plan of the jaws. Fig; 4.- is a plan of amodification of this extractor. Fig. 5 is a side elevation thereof.
Similar reference characters refer to like parts throughout the several views.
'l he handles 1 and. 2 Oil this extractor only be 01 any desired size and shape, but I meter to :iorin one pointed and the other with a chisel end. The aws beyond the rivet- 3 may be in practical. alincment with the handles, as indicated in Fig. l, or at an angle thereto. as indicated in F An essential part oi? the tool is a pointon one jaw, whether it extends at right angles to or is parallel to the rivet.
In Figs. 1, 2 and 3, the jaw at is bent so that the point 5 is substantially parallel to the rivet 3. The end 6 oi the jaw 7 is also bent across the end of the pointed jaw so that it may "form a fulcrum in the general plane of the tool. ll hen it is desired to remove a cotter pin 8 from a castellatcd not 3-), as indicated. in Fl 1, which is often very diilicult to do because of the location of the nut, the point 5 is worked into the eye 10 ot' the pin, as shown in Fig. 1, after which the handles are brought together. The end 6 rests on the nut 9 and acts as a fulcrum and the re sult is an easy and quick extraction of the cotter pin.
It the eye 10 were at right angles to the position shown in Fig. 1,the tool shown in Figs. at and 5 may sometimes 7e or great value, especially when the work can alone be reached by a tool whose handles 11 and 12 are at right angles to the aws. In this case, the jaw 13 is substantially straight and. pointed and. the fulcrum j aw let has its end 15 bent to extend adjacent to the pointed end of the jaw 13.
In all of these forms, the aws must be so termed that they may swing past each other for otherwise the pins could seldom be entirely extracted from the mechanism on which the fulcrum jaw is resting.
It will be understood that the details and proportions of the various parts may all be changed without departing from the spirit of my invention as set forth in the following claims.
I claim 2- 1. A cotter pin extractor consisting ot a pair of handles pivoted together and jaws on the handles adapted to swing past each other as the handles are brought together, the end oi? one of the jaws being pointed, a nd the end. 01 the other aw being bent to extend across beyond the pointed jaw.
2. A. cotter pin extractor consisting ot a pair of handles pivoted together and ja vs on the handles adapted to swing past each other as the handles are brought together, the end of one oi the jaws being pointed, and the ends of both the jaws being bent to overlap.
