ADOLPH NYHUS, OF LA CROSSE, WISCONSIN.
GOTTER-PIN EXTRACTOR.
Specification of Letters Patent.
Patented July 20, 1920.
Application filed December 24, 1919. Serial No. 347,073.
tors, of which the following is a specification.
This invention relates to extracting devices specially adapted for removlng cotter pins; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a side View of a cotter pin extractor constructed according to this invention. Fig. 2 is a perspective view of the triangular a-w. Fig. 3 is a detail view showingrhow the jaws engage the cotter pin.
Two opposed jaws 2 and 3 are provided on the ends of crossed and pivoted shanks 4 which work on the pin 5 like shears. One jaw 2 is conical and terminates in a point. The other jaw 3 is triangular in cross-section, and its face is arranged radially of the pivot pin 5, and so that the point of the conical aw 2 comes against its outer angle, and with one side of its face parallel to the pivot pm 5.
This formation of the jaws enables them to engage with a cotter pin 6 as shown in Fig. 3, and open out its loop when same has become distorted. One shank or handle also has a hook 7 which can be used occasionally; (The triangular jaw can be used for spreading the end portions of the pin, and also for straighteningthem before extracting the pin.
\Vhat I claim is:
An extractor for cotter pins, comprising two crossed and pivoted shanks, one shank having a jaw provided with a flat triangular face arranged radially of the pivot of the shanks with its base parallel to the said pivot, and the other shank having a curved and conical jaw the point of which is ar-' ranged opposite to the apex portion of the said triangular face.
In testimony whereof I have aifixed my signature.
ADOLPH NYHUS.
