SPECIFICATION forming part of Letters Patent No. 402,663, dated May '7, 1889.
Application led .Tammy 18, 1888. Renewed Ianuary 29, 1889. Serial No. 297,982. (No model.)
To @ZZ whom it may concern:
Be it known that I, WILL/TRD D. DoREMUs, acitizen of the United States of America, residing at Vashingtomin the District of Columbia, have invented certain new and useful Improvements in Padlocks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of'reference marked thereon, which form a part of this specification.
My invention has relation to improvements in padlocks; and the object is to improve eX- isting lock mechanisms and increase their security against false keys and knavish manipulation.
My invention consists in the novel construction of parts and their combination, as will be hereinafter fully described, and specially as the same is particularly pointed out and claimed herein.
I have fully and clearly pointed out my improvements in the accompanying drawings, wherein- Figure l is an elevation of the padlock with one of the plates removed, showing the mechanism in locked relation. Fig. 2 is a similar view showing the mechanism in unlocked relation. Fig. 3 is a similar view showing the tumblers removed and the key inserted, the lug of the detent-piece being shown as lodged against the end of the dog. Fig. 4 isa similar view showing the position of the elements when a straight key is inserted. Fig. 5 is a detail of the dog. Fig. 6 is a detail of the detent-piece. Fig. 7 is a detail view of one of the tumblers, showing the spring bent to act to release the dog. Fig. S is a detail of one of the tumblers, and Fig. 9 is a perspective of the key.
In the drawings the similar notations used in the different iigures designate like parts, and, reference being had thereto, A designates the lock-case consisting of face plates a, one only of which is shown, connected by a rimpiece, 1, in which are formed the usual open ings, 2 3, to take the hinge end and nose of the shackle, and having a key-hole, l). In the casing is pivoted the shackle 4, formed on its free end with notch 5, to engage the catch end of the dog. The shackle is pivotally mounted on a rivet, 6, and this rivet, in connection with those supporting the dog, the tumblers, and the stop of the detent, holds the casing tightly and securely together. In the heel of the shackle is a hole, 7, in which engages one arm of a spring, 8, mounted on a stud or rivet, 9, the other arm of the spring being lodged against the tumblerrivet, as shown, the purpose being that when the shackle is released Yfrom the dog the spring will lift and throw the shackle back, so that the lock may be removed from the staple or other object to which it is attached.
B designates the dog, pivoted on a rivet, 10, in the casing. This dog is formed with a notch, 11,to engage the nose of the shackle, and has an arm, 12, which is engaged by a spring on one of the tumblers, and is moved in engagement with the notches ofY the tumblers when they align. On the lower eXtension of the dog is formed a lug, 13, to engage the notches of the tumblers when in alignment, and in the edge of this 'lug 13 is a groove, 14, to receive a flange of the lug on the detent-piece.
In the casing is rigidly secured a key-guard, 15, arranged with its face nearest the keyhole, on an incline, to permit the end of the key to slide in freely and be guided into the space between its upper end and the stop and guide-pin, against which the arm of the detent rests. This guard also serves as a rest to hold the tumblers from falling down too far.
C designates the detent,-piece. This'is piv- IOO its support with its greatest diameter in the direction of the lug 13, as indicated in dotted lines, and so that when a straight key is inserted the arm 19 of the detent-piece is moved back, and the lug 17 thus moved down against the face end of the lug13 of the dog, stopping the dog from entering the notches of the tumblers, although they might be moved into alignment by the key. Across the face of the lug 17 is a groove, 18, leaving a flange on the outer edge of the lug, the purpose being to permit the ange of the lug 17 to move down under the groove 14. of the lug 13 on the dog, when the detent is moved by the insertion of the key, and this also permitting the arm 19 of the detent to be pushed back and the detent to be rotated far enough for the key to be withdrawn. Below the lug 17 is a notch, c, in which the lug 13 of the dog enters, when the lock is unlocked, as in Fig. 2, and specially as shown in Fig. 3 of the drawings. The detent-piece is also formed with an arm, 19, carried down to the rim of the case and terminating in an angular lng, 20, the face end of which sets at an incline across the key-hole of the lock, substantially as seen in the drawings. A spring, 21, is fixed in the detent and operates to always throw it in normal position, and to limit the movement of the detent a pin, 22, is fixed in the case. The pin, 22, also serves as a key-guide in connection with the keyguard 15. The spring 21 may bear against the rivet 23, as shown. A lkey-seat, 24, is formed in the under side of the detentpiece, into which the end of the key projects.
D designates the tumblers, which are pivoted on the rivet 23, and are of the usual form, as shownin Figs. 7 and 8, the springs being arranged to bear backward against the rim of the case, except that in one instance I utilize the spring of one, as 25, to throw the dog fromengagement with the shackle when the lock is unlocked by arranging the free end of the spring to bear upon the arm 12 of said dog, as seen in Figs. 1 and 2 of the drawings.
E designates the key having the requisite number of steps 26 to engage the tumblers, and formed with a notch, 27, bent or struck in the shank, the purpose of the notch being to provide a seat for the free end of the arm of the detent-piece to rest in after the key is inserted and the tumblers are lifted, and thus permit the lug 13 on the dog to engage the notches of the tumblers and that in the detent.
The parts may be assembled in the case by arranging the shackle on its rivet7 then adjusting the spring which lifts it in place, then putting the dog on its rivet, then arranging the detent -piece in position, then mounting the tumblers with the springs bearing as shown, and then adjusting the cover or face-plate on and riveting it in the usual manner. The lock is manipulated by inserting the key and pressing it in until the end of the arm of the detent moves into the notch of the key, when by continued pressure the tumblers are lifted to align and the dog released and thrown with its lug into the notches. The key may be withdrawn when the lock is unlocked, and then the parts thrown in locked position by simply forcing the nose of the shackle into the case and under the catch of the dog.
1. In a padlock, the combination, with the tumblers and the dog, of a detent-piece, C, pivoted in the casing, and formed with a lug to engage the end of the dog and prevent it from engaging the notches of the tumblers, and an arm terminating in an inclined end piece to set across the key-hole of the lock, substantially as and for the purpose stated.
2. The combination, with the casing, of the key-guard and tumbler-rest 15, arranged at an incline over the keyhole, the tumblers pivoted to rest on the guard and rest 15 in their downward movement, and the detentpiece pivoted on the lock and formed with an arm adapted to set across the key-hole, substantially as and for the purpose specified.
3. The combination, with the casing having the shackle, of the spring actuated dog having a lug to engage the notches of the tumblers, the tumblersLa detent-piece pivoted in the casing and formed with a lug to engage the said lug of the dog and an arm terminating in an angular piece to set across the keyhole, and a key formed with an angle in its shank, whereby the tumblers may be lifted and the detent moved out of engagement with the dog, substantially as described.
In testimony whereof I afi-"1X my signature in presence of two witnesses.
