llad-Locks.y FMLN-7,585. Patented Feb.17.1874.
UNITrmN STATES PATENT OFFICE..
HERRMANN AHREND, OF NEWARK, NEW JERSEY, ASSIGNOR TO ROMER` 8L CO., OF SAME PLACE.
IMPROVEMENT IN -PADLocKs.
Specification forming part of Letters Patent No.147,585, dated February 17, 1874; application filed `January 14, 1874.i
To all whom it may concern:
Be it known that I, HERRMANN AHREND, of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Padlocks; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification.
. The nature of my invention consists in the construction and arrangement of a padlock, as will be hereinafter more fully set forth.
In lorder to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is an interior view, showing the lock closed. Fig. 2 is 'a similar View, showing thelock open. Fig. 3 is a cross-section through the line Fig. l; and Fig. et is a side view ofthe key.
A represents the lock-case, and B the shackle or hasp, constructed in any of the known and usual ways, one end of the hasp being pivoted and the other end entering the case, to be fastened by a bolt. The entire interior mechanism of my lock consists of two piecesa bolt, C, and a spring, D. The bolt U is pivoted at a, and has a projection, b, at its upper end, to enter the slot in the hasp B for closing the lock. Below the pivotpoint a is a slot or notch, in the bolt, and below the same the bolt has a projecting arm, d. The spring D passes around a pin, f, at the opposite side of the lock-case, the upper end h of the spring bearing against the end of the hasp B, while the lower end i of the spring rests against the bolt C below the notch a' and under the arm D. The key Gr has two wards, y and z, and, when inserted in the lock and turned, the ward y raises the end 'i of the spring until it comes opposite the notch when the ward z takes hold of the arm d, and turns the bolt on its pivot, so as to withdraw the hook b from the hasp, and the upper end 7L of the spring forces the hasp open. In closing the hasp, the end l1. is depressed, and as soon as the hook b comes opposite the slot in the hasp the end i of the spring closes it.
The spring D thus answers three different purposes, viz; It acts as a tumbler, resting firmly against the bolt, so that it is impossible to open the lock until the spring has been raised by the key sufficiently to admit it in the notch w. It acts as a spring to throw out the shackle or hasp, and holding the bolt open when unlocked. It acts as the spring-power, when the shackle is closed, to move the bolt in the shackle.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The spring D, constructed as described, and arranged in a padlock, to act as a tumbler, throw the hasp open, and move the bolt, substantially as herein set forth.
2. The spring D, constructed as described, and arranged to act as a tumbler, and to throw out the hasp, in `combination with the bolt C, having hook b, notch x, and arm d, all constructed as and forV the purpose specified.
In testimony that I claim the foregoing as my own I aftlx my signature in presence of two witnesses.
HERRMANN AHREND. Witnesses:
REUNE J. D. DUNN, ABRAHAM MANNERs.
