UNITED STATES PATENT OFFICE..
SAMUEL A. BRUMBAGH, 0F HARRISBURG, PENNSYLVANIA.
IMPROVEMENT IN vNUT-LOCKS.
Specilcation forming part of Letters Patent No. 172,960, dated February 1, 1876; application filed f i January 7, 1876. v
lock for the fish-plates.- railway-joints, and for other purposes in which the nutsl areexposed to vibratory strain; and the invention consists of screw-bolts'with nuts which are set into recesses ot' washerplates provided at the under side with ratchet-teeth. The Washers of two adjoining nuts are connected by a key that enters the ratchets by a point and tooth at diagonally opposite ends, and locks thereby the nuts.
In the drawing, A represents a rail-joint fish-plate, or any other part ot' machinery that is to be rmly lockedg'B, the connecting-bolts, and C, the screwfnuts that are countersunk into correspondingly-recessed Washers D.
The washers D are provided at the lower side facing the iish-plate with ratchet-teeth @,'cas't or otherwise applied thereto. A key, E, extends froin one washer to the other, being made of arc shape at one end, so as to encircle the ratchet of one Washer, by whosev overlapping tlange and raked tooth the key is retained. The opposite end or point of the key E enters the teeth of the adjoining Washer. The arc-shaped end of the key is further provided With a projecting tooth, a, which is t.
nearer to one end of the same, so as to be diagonal to the point of the key..
When thekey is applied, the nut and washer to which the arc-shaped part of' the key is applied is screwed up tight, until the point of key rests on the outer teeth ot' the adjoining washer, which is then screwed up as tightly as possible, so that the point of key catches at inside of a tooth of the same. The washer that engages the point ot' key is then slightly unscrewed, which forces the tooth of the arcshaped end of the key in diagonal direction into the first Washer, as shown in Fig. 1, so as to produce the perfect locking of the nuts, of which one serves to hold the other rigidly in position.
Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- A nut-lock for fish-plates of rail-joints, &;c., composed of a connecting-key, locking With an arc-shaped and toothed end into the toothed and recessed washer of one screwnut, and by its pointed opposite end diagonally to said projection or tooth into the toothed and recessed washer ot' the countersunk screw-nut ot' the adjoining bolt, substantially in the manner and for the purpose set forth.
