UNITED STATES PATENT OFFICE.
HENRY RITOHIE, OF NEWARK, NEV JERSEY, ASSIGNOR TO HENRY RITCHIE, SAMUEL C. THOMPSON, AND G. W. WESTERFIELD.
PADLOCK.
Specification of Letters Patent No. 9,963, dated August 23, 1853.
To ZM 'whom t may concern.'
Be it known that I, HENRY RITCHIE, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Spring-Padlocks; and I do hereby declare that the following is a full, clear, and lexact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a view of my improved padlock, in a locked state; the front plate of the case being removed in order to show the interior. Fig. 2, is the same View as Fig. 1; the padlock being unlocked.
Similar letters of reference indicate corresponding parts, in each of the two iigures.
This invention relates to a new and use ful improvement in spring padlocks, and consists in the combination ofa bolt, toothed tumbler, and guard, so arranged as to prevent the bolt from being forced from the shackle in the bow, by means of blows, or by violently striking the case of the lock; the toothed tumbler also allowing the lower end of the bow, when pressed in the lock, to operate the guard, and thus allow the bolt or its projection to pass into the shackle.
To enable others skilled in the art to fully understand and construct my invent-ion, I will proceed to describe it.
A, represents the case of the lock, which case is of the usual form; and, B, is the bow, attached tothe case, A, in the usual manner; (a), being the pivot of the bow.
C, is the bolt within the case. This bolt is of irregular form, as shown in both figures; and it works upon a pivot, The upper spur or projection, (c), is the portion of the bolt which passes through the shackle, (d), of the bow, B. The position of the shackle is shown by dotted lines. The spring of the bolt, C, is represented by, (e).
D, is a tumbler, working on a pivot, (f) see dotted lines. This tumbler is underneath or behind the bolt, C. The spring of the tumbler is represented by, (g). On the upper part of the tumbler there is a small rounded prominence or tooth, (n), which passes into the shackle (d) and rests or bears against t-he edge of the spur or projection, (c), when said spur or projection is in the shackle; as seen in Fig. 1. On the right side of the tumbler, there is a projection, (7L), which rests or bears upon a ledge (z',) when the parts are in the posi tion shown in Fig. 1. The spring, (g), keeps the tumbler in this position. On the projection, (la), there is a tooth, (j), which bears against the right side of the bolt, C, and underneath a notch in the bolt, when the parts are in the position shown in Fig. 1.
E, is a guard or lever, having its fulcrum at, (7c). This guard is kept firmly upon the upper part of the bolt, by a spring, U); and the outer edge of the guard is opposite a shoulder, (m), in the upper part of the bolt, that is, when the parts are in the position shown in Fig. 1, and the padlock is in a locked state.
By referring to Fig. 1, it will be readily seen that, when t-he padlock is in a locked state, it is impossible to force back the bolt or drive the spur or projection, (c), from without the shackle, (CZ) because the tooth, (j), bears against the right side of the bolt, C, and underneath the notch, and the guard, E, against the shoulder, (m). In order t0 withdraw the bolt from the shackle, the guard, E, and tooth, .7', must first be elevated or raised so as to clear the bolt. This is done by means of the key, which irst acts upon the tumbler, D, and raises the stop, (j) the tumbler also raising the guard, E. The key then acts upon the bolt; and the spur or pro ject-ion, (c), is withdrawn from the shackle, (al). When the key is turned entirely around, the parts return to their original position; and in order to lock the bow, B, it is merely pressed downward; the lower end of the bow forcing back the prominence, (n), and causing the tumbler to free the guards from the bolt, until the shackle, (d), comes opposite the spur or projection, (c), when said spur is forced into the shackle, by the spring, (e), of the bolt.
am aware that several devices have been employed for preventing the bolt from being forced backward by striking the case of the lock. H. C. Jones has one patent in which he employs two bolts; one termed a slide bolt, and the other a turning bolt; both of these bolts work or pass into the shackle; and 'the idea is, that if one bolt .be forced out of the shackle by blows, the other bolt will remain in the shackle. There is no doubt but what this plan is an improvement over the single bolt originally used; but two bolts may be forced fro-m the shackle by repeated blows; as H. C. Jones employs no guard or stop; neither has he a tumbler and bot-h bolts are also liable to derangement by striking the case. In my improvement, I employ only one bolt; and I prevent that bolt from being deranged or forced back by blows, by means of the tumbler and guard.
I-Iavng thus described my invention, What I claim as new, and desire to secure by Letters Patent, s-
The combination of the bolt, C, guard, E,
and the double toothed tumbler, D; one tooth, (n), of said tumbler, ttng in the shackle, (d), and the other tooth, (j), ttng in the notch at the back of the bolt. The
bolt, guard, and tumbler operating as set l5 forth in the body of the specicaton.
