' W. H. HORN COTTER PIN REMOVER Filed June 20, 1923 To all whom it may concern:
comma-rm 1.
n. HORN, or POLLOCK, sourn'nanora.
Application filed June 20, 1929.. Serial recesses.
Be it known that I, WILLIAM H. Home, a citizen of the United States, residing at Pollock, in the county of Campbell and State of South Dakota, have invented certain new and useful Improvements in Cotter-Pin Removers, of which the following is a specifica- 1 tion.
' ceivee the said shank 1.
.as indicated by the numeral of wood or any washer 8 relates to tools for use in extracting cotter pins. It frequently happens that cotter gins which require to be extracted are foun .to be so located that they cannot be reached by ordinary tools or, if reached, suflicient pulling force cannot be exerted to extract the pins. The present invention, therefore, aims to provide a tool which may be employed under the conditions above recited as well as under more favorable conditions, and which will permit of cotter pins being extracted with case where ordinarily considerable labor and time would be consumed in accomplishing this result.
In the accompanying drawings:
Figure 1 is a vertical longitudinal sectional view through a cotter pin extracting tool embodying the invention;
hEigure 2 is a view in side elevation of the too Figure is a detail transverse sectional view on the line 3-3 of Figure 1 looking in the direction indicated by the arrows.
This invention The tool embodying. the invention .com--' shank which is indicated by the 1 and which atone end is threaded 2. A handle 3 other suitable material is bore 4 .of a diameter to fit prises a numeral provided with a the shank, and the handle is fitted uponthe threaded end of the shank and constitutes a hand grip by grasping which the tool may be held in one hand 1n proper en gement with the cotter pin to be remove A 'nut 5 is threaded onto the ortion 2 of the shank 1 and bears against the inner-or lower end of the handle 3, the nut the said threaded portion of the shank. second nut 7 is threaded onto the threaded extremity ofthe shank and bears against a which in turn bears against the op site or outer end of the handle 3;
being driven transversely through the shank 1, as clearly shown in Figure 1 of the drawings.
Theopposite end of the shank 1 is reduced in diameter and threaded as indicated by the the said shank 1s fitted into a threaded socket 20 formed {in an extracting head 21 which is in this manner associated with the said shank. The ektracting head 21 is provided with two prongs one indicated by the numeral 22 and the otherby the numeral 23. The prong 22 is curved laterally obtusely to the axis of th shank 1 and is gradually tapered from inner to its outer end, the said prong being of substantially circular contour in cross section throughout its length. The other prong, 23, is likewise curved laterally but substantially to hook form, it being therefore substantially in the form of a hook having a pointed entering end 24 presented substantially in the direction of the handle end of the shank. As compared contour of this prong, it will be noted by reference to Figure 1 of the drawings, that the pointed end of the prong 22, which end is indicated by the numeral 25, is presented at an angle away from the reduced end or forward end of the shank.
In the use of the tool embodying the 22 is worked nto pin to suitably open or expand the same, 1f this should be found. desirable or an: ry, and after this has been done the pointed end 24 of the prong 23 is hooked into the eye of the pin, and, with the handle 3 in one hand, the other hand is employed .to sha ly slide the hammer member rearwar y upon the shank 1 to pact against the nut 5 and thus transmlt a sudden pulling force to the cotter pin for "purpose of extracting-the same.
It w111- further be observed that the deliveran in with the pointed-.end 25 of the prong 22 projects be-i Y yond the foremost part of the prong so that the said rong 22 may be worked into the eye-of e cotter pin without any interference on the part of the prong 23 reason of said prong23 00111251111170 contact with any adjacent part. It also be noted that by rem vabl fitting the head Y 21 onto the red eeden and by employing the key or taper in 12 as an abutment for the hammer mem er 9, the head 21 may be readily removed and a new or difl'er'ent shaped head substituted therefor,'andlikewise by removing the said head and the pin 12, the member 9 may be removed from the shank. Also it will be evident that the nut 5 or any equivalent part of the handle securing means, and the taper pin or key 12 constitute spaced abutments upon the shank between which the hammer member is disposed and slidably movable.
Having thus described the invention, what is claimed as newis:
1. A cotter pin remover comprising a shank, a hammer slidably mounted upon the shank, and a head. detachably secured to one end of the shank and provided with spaced diverging prongs, one of which is hookedshape and constitutes an extracting prong, the other pron being disposed substantially in the longitudinal plane of the shank and provided with a pointed terminal deflected laterally with respect to the shank and constituting an expanding prong.
2. A cotter pin remover comprising a shank having one end thereof provided with a reduced threaded extension, a handle fixed to the opposite end of the shank, a hammer member slidably mounted on the shank between the threaded'extension and handle, and a detachable head having a threaded socket formed therein adapted to receive the threaded extension of the shank and provided atone side with a hooked-extracting prong curving laterally and having its entering end presented substantially in the direction of the handle and at its opposite side with a tapered expanding prong disposed substantially in the longitudinal plane of the shank with its entering end pointed and deflected laterally away from'the firstmentioned prong.
In testimony whereof I afix my signature.
