GEORGE D. SPIELMAN, OF LANCASTER, OHIO.
PADLOCK.
SPECIFICATION forming part of Letters Patent No. 256,399, dated April 11, 1882.
' Application filed July 30, 1881. (Model) To all whom it may concern:
Be it known that I, GEORGE D. SPIELMAN,
of Lancaster, in the county of Fairtield and State of Ohio, have invented a new and Improved Padlock, of which the following is a full, clear, and exact description.
The object of my invention is to provide a new and improved padlock which is locked automatically when its jaw is pressed in and.
will spring open as soon as its'key is inserted.
The invention consists in a novel construe tion and arrangement of parts, as hereinafter fully described.
In the accompanying drawings, Figure 1 is a longitudinal elevation of my improved padlock. Fig. 2 is a rear end elevation of the same. Fig.3 is a front elevation ofthe same. Fig. 4 is a longitudinal elevation of the key. Fig. 5 is a longitudinal elevation of the lock,
showing the side plate removed and the lock closed. Fig. 6 is a longitudinal elevation of the same, showing the side plate removed and the lock opened.
Similar letters of reference indicate corresponding parts. I
In the drawings, ajaw, A, with a recess, B, in the under side of the front end,is pivoted in the lock-casing O, and the inner rounded end of this jaw is provided with two recesses, D
0 and E. A spiral torsion-spring, F, is wound around the pivot G of thisjaw and forces the jaw to swing upward. A series of tumblers, H, each one of which has a slightly different shape, and all of which have a different-shaped 5 hook or projection, J, at the lower end, are
pivoted in the casing O by a pivot, K.
Each tumbler H is provided at its rear edge with a band-sprin g, L, the upper end of which rests against the casing G. The casing O has a transverse slot, M, in its rear, and through this slot M the key N is passed into the look. This key is made of sheet metal, and has as many projections and recesses in the front end as there are tumblers in the lock; 7
5, The casing (J is provided with a rigid jaw, O,having a stud,P,at its front end,the upper end of this stud fittinginto the aperture B in the pivoted jaw A.
The operation is as follows: If the lock is locked, the upper ends of the tumblers H are in the recess E of the rear end of thejaw A, and are held in this position by the springs L, fixed in the tumblers. If an attempt is made to force open the look by forcing the outer end of-thejaw A outward, the tumblers will prevent this; but the strain will not be on the pivot K, as the lower rear corner or shoulder, T, of the tumblers rests in a notch, R, in the rear wall of the casing U, as shown in Fig. 5. If a skeleton-key, or any other key not prop- 6o erly fitting the lock, is inserted, some of the tumblers will be pushed forward too far, others not enough, and the projections J of those tumblers that are'pushed inward too far will pass into the notch D, and will thus prevent thejaw A from being opened; but if the proper key, the notches and recesses of which are made to fit the tumblers, is inserted, all the tumblers will be pushed back simultaneously, and their upper ends will leave the notch E, thus releasingthe bolt A, which is forced outward by the spring F, as shown in Fig. 6.
To look the padlock, all that is necessary is to press the jaw A inward,when the lug S between the notches D and E presses back the lower ends of the tumblers, so that the upper ends of the same pass into the recess E again, in which they are held by the springs L.
By varying the shape and number of the tumblers any desired number of different locks can be produced, each of which can be opened by its corresponding key only.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a padlock, the C0lIlbl[1 t1l)lOll,Wlththe casing 0, provided with the stationary jaw 0, having stud 'P, the pivot G, the tumblers H, and springs L, of thejaw A,provided with the recess B in the under side of its outer end, and
.the recesses D E on its inner end, and the spring F, wound around the said pivot, substantially as and for the purpose set forth.
GEORGE. DANIEL SPIE LMAN.
