Specification of Letters Patent.
Application filed February 26, 1914. Serial No. 821,296.
To aZZ whom it may concern .1
3e it known that l, HENRY G. MoCoMn, a citizen of the United States, residing at New York city, county of New York, State of New York, have invented certain new and useful Improvements in Cotter-Pins, of which the following is a specification.
lily invention relates to all split pins, such as cotter pins, split keys and similar devices, and the objects of my invention are to provide an improved construction of such devices, but particularly of cotter pins, whereby they may be readily spread or opened butwhich costs substantially no more to manufacture than the usual forms of such devices.
My pins or keys are substantially like those now common, except that I provide each with a sufficient bevel along the side of a tang, (preferably a bevel along each s de of each tang) to allow the ready lnsertion of a blunt pointed instrument between, and the spreading of, the tangs By extending the bevel or be'vels continuously the full length of each tang, the pin or key may be spread from any point along its length. In the particular case of cotter pins, the bevels preferably extend continuously from the end of a tang, around the eye and back to the end of the other tang, since in addition to the other advantages, the blank of such a cotter pin may be as readily drawn as the ordinary, substantially semi-circular blanks. It is immaterial to my invention whether the bevel or bevels have plain or other surfaces so long as a spreading tool may-be readily introduced there ,rerred form of cotter A tron my invention pinthrough whic I d ooth in its broad may be readily u and specific aspews.
In the accompanying drawingl have illustrated. 'in perspective my improved cotter p This cotter pin comprises two substantially semi-circular tangs 1 and 2 joined by the eye Both "es of both tangs are provided with bevels 4:, which extend from an end of one tang, around the eye as shown at 5, and back to the end or the second tang.
In this case the surface of each bevel is plain and at an. angle approximately 45 to the flat ii er surface of the pin. Almost any 1 n tool, however blunt, as, for t driver, directed by the beveled surface, may be readily inserted be tween the tangs of such a cotter pin at .vh atever point it may be desirable to spread the tangs'. Considerable time in spreading the tangs is thereby saved and the blank for such a pin may be as readily drawn as the blanks of the usual and more strictly semicircular forms. A certain amount of metal may also be saved approximating an eighth of the total amount heretofore necessary for a given size of pin. It is to be especially noted that the ends of the tangs are well rounded, that the fiat faces are in direct contact throughout their entire length andthat while the beveled portion of each. tang extends from the eye to the end they do not extend around said end. This latter feature, and also the rounding of the end, greatly facilitate the insertion of the pin in place and permit of the tangs being spread from any point along their length.
I am aware that for a long time prior to my invention, probably substantially ever since cotter pin blanks were first drawn like wire through dies, the edges have not been formed by surfaces meeting at right or acute angles to each other, but the edges have been somewhat rounded as it is well understood by those skilled in wire drawing to be necessary. The curvature of the rounding of these edges has been on radii of the order of 'inch, which altogether fails to obtain the results I contemplate. I do not of course, intend to cover such prior constructions in the appended claims, but I do contemplate certain modifications of the construction. I have illustrated which also embody my invention, and I intend in the claims to include all such modifications.
What I claim as new and desire to secure by Letters Patent of the United States is 1. A split pin comprising two adjacent tangs, one of said tangs being beveled along a side adjacent the other tang, the bevel extending from substantially the head of the pin to substantially the end thereof to allow the ready insertion at the side of a blunt pointed instrument to spread the bangs.
2. A split pin comprising two adjacent tangs, one of said tangs being beveled along a side adjacent to a second tang adapted to allow the ready insertion at the side of a blunt pointed instrument to spread the tangs.
3. A cotter pin comprising two adjacent Fail lid
tangs, one of said tangs being provided with a continuous bevel extending along a side from substantially the end thereof to the eye, around the eye, and along-the adjacent edge of the second tang to substantially the end thereof adapted to direct the insertion of a blunt pointed instrument'to spread the "tangs.
4. A cotter pin provided With an eye and two parallel engaging tangs which present an nnbroken end surtace to facilitate insertion of a spreading tool.
In Witness whereof, I have hereunto set the insermy hand this twentieth day of. February 1914.
