GEORGE D. BULMER AND CHARLES BULMER, OF WHITE HOUSE, ASSIGNORS OF ONE-THIRD TO VILL'IAM R. JONES, OF BRADDOOKS, PA.
NUT-LOCK.
EBPEGIFICATIQN forming part of Letters Patent No. 325,235, dated September 1, 1885.
Application filed June 11, 1885.
To all whom, it may concern:
Be it known that we, GEORGE D. BULMER and CHARLES BULMER, of White House, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Im provement in Nut-Locks; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which Figure l is a plan View of the blank of our improved nut-lock. Figs. 2, 3, 4:, and 5 are top, edge, side, and perspective views of the finished lock. Fig. 6 is a section of a railjoint showing our improved lock in position. Like letters of reference indicate like parts. Our improved nut lock is made of steel. It is cut out of a plate of the proper thickness by suitable dies to form the blank shown by Fig. 1. This blank has two rings, a, the adjacent edges of which are united by a narrow web or filament, 1). Each ring is severed or cut, as at c, on one side, preferably in a plane off the center, to make a better cutting-edge, and the cut in one ring is on the opposite side from the other. The blank is then bent at the web or filament b, so as to fold the rings a together. This folding is done in such a manner as to bring the short arms a closely in contact with the adjacent part of the blank, while the long arms a are separated and extend in opposite directions and their ends curved outward or bent into helical shape. The points may be bent out at the time of folding the blank by interposing a suitable tool between the ends, or it may be done when the blank is stamped or cut out, or otherwise, as may be desired. The blank having been folded or bent so that the rings assume a helical form and the edges a turned out, the lock (N0 model.)
is complete and ready for use. When put on a rail-joint, it is placed on the bolt (Z between the fish-bar e and nut f. In screwing up, the nut slips over the ends a as on a ratchet, and they are compressed between the adjacent surfaces of the fish-bar e and nutf, and give the desired spring action to thejoint. The two ends a being opposite, support thenut equally 011 both sides and prevent its canting on the thread. If it is attempted to turn back the nut, the edges a bite into the surface of the fish-bar e on one side and nut f on the other, and prevent accidental unscrewing and necessit-ate the use of considerable force in intentional unscrewing.
Our improved lock has remarkable strength, a very long and effective spring action, holds with great tenacity, and can be made at a reasonable cost.
\Vhat we claim as our invention, and desire to secure by Letters Patent, is-
l. A nut lock consisting of two helical rings united together at one edge and curved in opposite directions, substantially as and for the purposes described.
2. A nut -1ock consisting of two helical rings united at one edge and folded together so that the adjacent ends overlap and extending in opposite directions, so that the outer separate ends terminate on opposite sides of the center, substantially as and for the purposes described.
In testimony whereof we have hereunto set our hands this 8th day of June, A. D. 1885.
GEORGE D. BULMER. CHARLES BULMER.
