SPECIFICATION forming part of Letters Patent No. 430,815, dated June 24, 1890.
7 Application filed March 17, 1890. Serial No. 344,097. (No model.)
To all whom it may concern.-
Be it known that 1, DAVID M. THOMAS, residing at Audenried, Carbon county, and State of Pennsylvania, have invented new and useful Improvements in Padlocks, of which the following is a specification.
The object of my invention is to construct a lock of the character stated in such a manner as to form a safe and durable fastening, practically from the danger of being picked, and which can only be unlocked when operated by those familiar with its workings; and, further, to arrange and construct the several parts so as to form a simple and effective lock, readily understood and operated, and positive in its action and ultimate result.
My invention consists in the peculiar construction and novel arrangement of the parts thereof, all of which will be hereinafter fully described in the specification and particularly pointed out in the claims, reference being had to the accompanying drawings, in Which- Figure 1 is a front view of my improved padlock. Fig. 2is a similar viewthereof with the cap-plate removed. Figs. 3 and 4 areeviews of the same, hereinafter specifically referred to; and Fig. 5 is a detail perspective view of the tumbler and the locking-bar.
In the accompanying drawings, A indicates the easin g, preferably constructed of the form shown.
B is the shackle, pivotally secured at one end to the casing, its opposite end being pro vided with a tonguehavinga slot, which fits in the soeketd and is adapted to be en gaged by the beveled end of a spring-actuated locking-bolt 0, operating in a socket c and provided with the usual shoulders c 0, arranged about the key-hole D, as shown, the said look so far as described being of the well-known construction.
Above and to the rear of the locking-bolt G, I arrange a chamber E, which consists of a central portion 6, a front section forming a' vertical socket e, a rear portion forming a vertical socket c and the horizontal channels c 6 connecting said portions 2 6' e as most clearly shown in Fig. 2 of the drawings.
F denotes a tumbler journaled to operate in the central portion 6 of the chamber E,
which is provided with a downwardly-projecting stud f, arranged to project in a recessed portion g of a bar G, arranged to slide in the channels 6 6 its ends adapted to alv t-ernately project into the sockets 6 e such movement being accomplished by turning the tumbler to the right or left, as the position of the parts may require. I
I denotes a metal ball held in the socket e, which serves to hold the bar G in locked position when the parts are adjusted to hold the locking-bolt in a locked or unlocked position.
J denotes a metal ball, preferably of somewhat larger diameter than the ball I, which, when in its normal position, seatsin the lower portion of the socket e to the rear of the locking-bolt C, and serves to hold same from being unlocked.
The tumbler G is formed with an extension which projects through the cap-plate, its outer end being preferably non-circular to receive the upper end of an operating-lever R, which also serves as the key -hole guard, being adapted to be normally adjusted over the keyhole.
The manner of operating my improved lock is as follows: \Vhen the parts are in the position shown in Fig. 2 of the drawings, they Will serve to hold the locking-bolt from being unlocked. Now, when it is desired to unlock the shackle the lock is tilted to a position shown in Fig. 3, which allows the ball I to run to the upper end of the socket e and be freed from the adjacent end of the bar G. The operator then moves the lever R to the left, which causes the lug of the tumbler to engage the edge 10 of. the bar G, and slides it across the socket 6 under the ballI, as shown in dotted lines, same figure. This movement permits the large ball to roll to the upper end of its socket 6 The operator then turnsthe lever to the right, causing the lug to engage the edge 20 of the bar and slide the same across the socket e andunder the ball J. The lock is then turned to its normal position, which causes the small ball I to again drop in front of the end 30 of the bar, the parts being then in the position shown in Fig. 4, which is the IOO of the proper key. To place the parts again into position to hold the bolt 0 from movemen t, the lock is again tilted, the ball I leaving its position and the bar G slid to the left. The lock is then again turned to its normal position. The ball J will drop behind the bolt 0, and the bar G then slid to the right, allowing the ball I to again drop into position in front of its end 30.
From the foregoing description, taken in connection with the drawings, it will be observed that my improved padlock in outward appearance is precisely similar to the ordinary padlocks now in use, and its construction is such that no new key or locking-bolt mechanism will be required.
My improvements, in connection with the ordinary padlock mechanism, While making a substantial lock, which will have all the requirem ents of a padlock as to simplicity, durability, and cheapness, will render the same practically impossible to be operated. by any one not conversant with the interior construction.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. In a padlock, the combination, with the casing, the shackle, and the locking-bolt, of a socket formed at the rear of bolt, adapted to receive the end of said bolt when slid back, a ball, a sliding bar adapted to be extended across said socket, whereby, when said lock is tilted and the ball rolled out of engagement with the locking-bolt, said bar may be slid under said ball and hold it up, and means for shifting said bar G, substantially as shown and described.
2. In a padlock, the combination, with the casing, the shackle, and the locking-bolt, of
a chamber E, formed over said locking-bolt, a socket 6 the channel 6 communicating with said chamber and socket, a tumbler j ournaled in the chamber E, a slide-bar operating in the channel, adapted to be engaged and operated by the tumbler, a ball disposed in the socket c and an operating-handle disposed on the outside of the lock and connected to' operating above the locking-bolt, arranged to operate the sliding bar G, and a combined key-hole guard and lever connected to the tumbler to operate the same, substantially as described.
4. In a padlock, the combination, with the casing, the shackle, and the locking-bolt, of a tumbler disposed over said locking-bolt, sockets e e fldisposcd one to each side of the tumbler, a sliding bar G, connected with the tumbler and adapted to be shifted in opposite directions by the reverse movements of the tumbler, a ball J, held in the socket 6 adapted to hold the locking-bolt in locked position, said bar G adapted to hold said ball J in position, and a second ball I, operating in the socket 12, adapted to hold the bar G in locked position when projected in the socket 6 and means for operating the tumbler, substantially as shown and described.
