Description
UNITED STATES PATENT OFFICE.
JAMES M. ALBERT, OF VANDALIA, ILLINOIS.
NUT-LOCK.
SPECIFICATION forming part of Letters Patent No. 536,118, dated March 19, 1895.
Application filed January 21,1893. Serial No. 459,144. (No model.)
.To @ZZ whom t may concern,.-
Be it known that I, JAMES M. ALBERT, of
vVandalia, in Fayette county, in the State of Illinois, have invented a certain new and usefnl Improvement in Nut-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
This invention relates to positive key locks for the screw-nut attach ment of bolts, the said key lock seated in recessed slots in said bolts, and bent over into recessed lock slots in said screw nuts; and said invention consists in features of novelty hereinafter fully described and pointed out inthe claim. r
Figure I is a side view of a bolt in which the locking key is inserted in its slot-bed, and the nut screwed into its operative position, the out end of the key being straight with its body previous to being bent within the recessed lock-slot of the screw-nut. Fig. II is an end view, and shows the out end of the bolt, the screw-nut seated thereon, and said uut provided with a radial series of recessed lock slots, in one of which the projecting end of the key is bent over,.and in a measure embedded to secure a permanent lock of Asaid Screw-nut to saidbolt. Figs. III and IV are detail, longitudinal sections, taken on line III-IV, Fig. I, and show the key embedded in its recessed seat `in the bolt respectively, before and after the lock-bend of said key into its radial recessed seat in the nut; and Fig. IV also shows, in broken lines, an additional key-slot, for use when it is required to double lock the nut. Fig. V is a'detail, side View, and shows amodification in which the radial series 0f lock-slots on the screw-nut are dispensed with, and the lock key is bent around the smooth face of the nut; and Fig. VI is a detail, side View; and shows a jamnut added to the combination. Said jam-nut may have a smooth outer face, as shown in said figure and in Fig. V, or it may be provided with like Aradial key bed slots, as are shown in Figs. II, III and IV.
Referring to the drawingsz-I represents the bolt, 2 the-head of said bolt, and 3'its screw.
4 represents the tapered slot or key-bed or beds, (as the case may be, when there is more than one key used,) recessed in said screw, and 5 is an angular enlargement at the head nut from its screw-bore l l.
of said key slot, in which the angular enlargement or head 6 of thelocking key7 is inserted. The said key is tapered or gradually enlarged in thickness from head 6 to its outer point 8, thereby providing the greater comparative strength at its turn locking end where it has to withstand the greatest strain, so as to effect a more reliable lock.
9 represents the screw nut, screw seated on said bolt; and l0 are tapered radial slots that diverge outwardly in the outer face of said After the nut has been turned into place, the out end 8 of the llock-key 7 is bent around into the radial slot bed l0, that at t-he time being registers with said lock-key, and said key thus besides locking the nut, is'itself locked in said slot of said nut, so that the abrasion against outside objects cannot easily break said locking point of the key from its stem, and thus endanger the unlocking of the nut.
9 represents a modification of the screwnut, in which the radial slots l0, are omitted, and the point 8 of the lock-key 7, is therein bent up against the unslotted face of said nut. The slot faced nuts of the previous figures are preferred, but this modified form may also be used.
l2 represents a jam-nut that may be screw seated on the screwtip of the bolt l outside the initial screw-nut, which jam-nut, while it may be used in combination with my slot faced nut 9, is more generally used with the modified, smooth faced nut 9', to provide an extra security to the hold of said nut on its screw bolt, as said smooth'faced nut, does not provide the extra security that is found in the recessed, radial locking beds lO, in which the locking point of the key engages. When said jam-nut is used, the lock-key 7 extends through and beyond said jam-nut, and its locking point 8 is bent around against the face 0f said nut, as shown in Fig. VI. The jamnut may have a plain face, as shown in Fig. VI, 0r it may be provided with recessed, radial slots 10, as shown in Figs. II, III and IV.
A single locking-key may be used, or two or more of said keys may be used, an equal number of ,slotted key beds 4 in the bolts being provided to that of the keys used.
While the nuts shown in Figs. I, II, III and IV, with recessed radial locking slots 10, for
IOO
lock bedding the bent points of, the keyor keys are preferred, as adding to the safety of the lock, and preserving the locking points of said key or keys from breakage by abrasion, yet the other elements of the device may be used in combination with smooth faced nuts, as shown in Figs. V and VI, andthe device may also be used when preferred in combination With a jam-nut 12, as shown in Fig. VI.
Vhen my lock-nut is used in connections of mowers, harvesters, and other traveling machinery in Whichthe lock-nut frequently comes in violent contact with stones, clods, roots, and other obstructive substances, a still further guard against the unlocking of the nut on such untoward occasions may be adopted, by slightly changing the routine of the combination. To eiect this, the outer point 8 of the lock-key 7 may be bent round into the recessed, radial locking slots l0 in the face of the screw nut 9 and the jam nut 12is then screw seated outside said nut 9, and its bent lock-key. The radial, recessedlocking slots in said case are preferably recessed clear across the face of the screw-nut 9, as shown in broken lines in Fig. II, and in broken lines in Figs. III and IV, and the locking point of the key is bent round and clearly embedded 1 in one of said recessed slots, so as not to interfere with the seating of said jam-nut. The
`III and IV, yet it may in some cases be bent downward instead of beinglaterally enlarged, and the head 5 of the slotted key-bed 4 is then slightly further counter-sunk into the bolt to provide a catch hold for said bent head of the lock key.
Iclaim as my invention- In a nut-lock, the combination of the screw bolt l provided with the longitudinal tapered slot or key bed 4 having the angular enlargement 5, the tapered locking key 7 seated in said tapered slot 4 and having an angular head or enlargement at its small end which fits in the angular enlargement 5 of the key bed, and the screw` nutengaging the screwthread of the bolt and fitting over the key 7, said nut being formed with tapered radial recesses deepest` adjacent to the bolt, and the `large end ofthe key beine` adapted to be bent :over into engagement with one of the recesses, lsubstantiallyas and for the purpose set forth.
