PADLIOCK'.
SPECIFICATION forming part of Letters Patent No. 278,229, dated May 22, 1883.
7 Application filed Augnst524,1882. (Noniodehi T 0 all whom itmay concern:
Be it known that I, FREDERICK EGGE, a citizen of the United States of America, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Padlocks, of which the following is a specification, reference being had therein to the taccompanyin g drawings.
My invention relates to padlocks, and has for its object to provide a device of this description, in which the shackle shall'have an automatic vertical sliding movement; and with this end in view my invention consists in providing a shackle extending through thecase of the padlock and projecting above and below the same, and adapted to be actuated by tumbler-springs in such manner as to produce an automatic vertical sliding movement of said shackle when the tumblers are operated upon by the key, as will be hereinafter fully explained, and then specifically designated by the claims.
In order that those skilled may more fully understand the construction and operation of my improved padlock, I will proceed to describe the same in detail, referring by letter to the accompanying drawings, forming part of this specification, in which Figure l is a plan view, showing the relative position of all the parts of my improved device when unlocked; Fig. 2, a similar view of the same when looked; Fig. 3, a detail perspective view of the shackle, and Fig. 4 a detail viewot' the key.
Similar letters denote like parts in the several figures of the drawings. 7
A is the shackle, which extends throughout the lock, and projecting above and below the case, and terminates at its lower end in a hook, 'B.- Near the middle portion of said shackle is an elongated opening, C, and at the side is a bearin g, D.
E is a pin,which projectsfrom either or both the upper and under surfaces of said shackle, and may be cast in one piece therewith, or driven through the same in any suitable man ner, all of which will be hereinafter fully explained. a
F is the post or pin, over which the shackle A and tumblers a b c, &c., are placed.
In assembling the parts of my improved padlock I first attach the chain to the hook B, and then place the tumblers and shackle over the post F in any suitablerelative order in such a manner that the pin E will be inserted within the slot H in the tumblers, while at the same time the bearing D will be above the springs a of the tumblers, as will be seen by reference to Fig. 1. Thelock is now in an unlocked condition.
The process and mechanism of unlocking are as follows: By depressing the shackle from the top or pulling it down from the bottom,the bearing D is forced against the springs of the tumblers, thereby compressing said springs, so thatwhen the shackle has been depressed to the full extent, and the pin E is accordingly without the slots in the tumblers, the latter will fly forward and assume the position as shown at Fig. 2. It will be readily understood that the shackle is held in this locked position by the abutment of the pin E against the edges of the tumblers above or below the shackle, as the case may be, but all force which would otherwise be brought to bear upon the tum-,
blers or the pin E is neutralized when the lock is used in connection with a chain or similar device attached to the hook end of the shackle, since the two forces exerted, the one at the top and the other at the bottom of the shackle, counteract each other, and the strain is upon the chain and shackle in a straight line.
The process of unlocking is accomplished as follows: I insert the key I within the key-hole J and against the tumblers. Thekey is stepped irregularly, being milled to correspond to the relative difference in the location of the slots or gatings H in the tumblers, so that when the latter are operated upon by the key the springs a will be forced against the bearing 1) and the slots or gatings H brought into alignment with each other and opposite to the pin E, the abutment to said pin being thereby removed. The latter, by the action of the springs a against the bearing D, shoots forward within the gatings H, and the shackle is thereby released.
It will be observed that my device by its construction is especially adapted to be used in connection with a chain, which latter is attached to the hook end of the shackle before roo . the latter is placed in its proper position within the case, so that it will be readily understood that when the chain is so attached and the lock has been riveted and is ready for use the chain cannot be detached without taking the lock apart.
Instead ofahook at the bottom otthe shackle, the latter may terminate at this point in any suitable form capable of ready attachment to a chain or similar device.
Having thus described myinventiomwhat I claim as new, and desire to secure by Letters Patent, is-
1. In a padlock, the shackle extending through the case of the same, and projecting above and below, and adapted to be actuated by the tumbler-springs, whereby an automatic vertical sliding movement of said shackle is produced when the tumblers are operated upon by the key, substantially as and'for the purposes hereinbefore shown and described.
2. In a padlock, as described, the shackle A, having central elongated opening, 0, bearing D, pin E, and hook B, extending through the lock and projecting above and below the case, substantially as and for the purpose set forth.
3. In a padlock, as described, the shackle A,
having bearing D and pin E, in combination with the tumblers, having slots or gatings H and springs a, substantially as and for the purposes hereinbefore described and set forth. In testimony whereof I affix my signature in presence of two witnesses.
