SAFE"LOCK' QSPECIFIOATION forming part of Letters Patent No. 591,200, dated October 5, 1897.
T aZZ whom it may concern:
Be it known that I, ANDREW'STEVENSON, a citizen of the United States, residing at Fllens burg, in the county of Kittitas and State of Washington, have invented certain new and useful Improvements in Safe-Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in burglar-proof safe-locks, and it contemplates the provision of a lock constructed with a view of preventing burglars from driving the dial pin or shaft and the tumblers through the lock'casing and thereby opening a safe.
The invention also contemplates the provision of means whereby in the event of the dial pin or shaft and the tumblers being driven wholly or partially through the loclocasing a stop will be automatically thrown into engagement with the bolt and by preventing inward movement of the same will effectually prevent opening'of the safe.
WVith the foregoing ends in view the invention will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which- Figure 1 is a transverse section of a portion of a safe-door equipped with my improvements, the same being shown as closed and locked. Fig. 2 is a section taken in the plane indicated by the line y yof Fig. 1. Fig. 3 is a similar View taken in the plane indicated by the line a: w of Fig. 1. fF ig. 4 is a section taken in the plane indicatedby the line w w on Fig. 2. Fig. '5 is a perspective view of the inner plate of the lock-casing. Fig. 6 is a perspective View of the plug for closing the opening in said plate. Fig. 7 is an enlarged perspective view, partly in section, of the sleeve in which the dial pin or shaft is journaled. Fig. 8 is an enlarged perspective view of said pin or shaft; and Figs. 9 and 10 are transverse sections taken in the planes indicated by the lines .2 z and p 19, respectively, of Fig. 1.
In the said drawings similar numerals indicate corresponding parts in all of the several views, referring to which 1 indicates the body of a safe, 2 the door Application fil d June 25,1897. Serial No. 642,258. (No model.)
thereof, and 3 the lock-casing at the inner side of the door, all of which may be of the ordinary or any suitable construction. The lock-casing 3 is provided with the usual opening 4 in its rear plate and the removable plug 6 for closing said opening, and it is designed to contain a locking-bolt 7, the usual spring-actuated dog 8, and the usual tumblers 9, which, in the position shown in Fig. 2, are designed to prevent movement of the dog and bolt, and, when their slots are coincident, are designed to permit the ,dog to rock in the direction indicated by arrow-and thereby permit withdrawal of the bolt from its keeper and unlock the safe.
11. indicates a sleeve which is disposed transversely of the door and is preferably formed of steel or Norway iron. This sleeve 11 is exteriorly threaded at its inner end to engage a threaded aperture 12 in the innerwall of the door 2, and is similarly con-. nected to the outer wall of the door and thereby held in position. Said sleeve is also secured in position by a screw-key 13, which occupies a threaded bore formed partly in the exterior of thesleeve and partly in the door, said key being designed to effectually prevent the sleeve from being turned and removed from the door by a person at the outer side of the same. The interior diameter of the sleeve 11 is reduced at about the distance shown from the outer end thereof to form a shoulder 14., and is further reduced at apoint adjacent to its inner end to form a shoulder 15, 'for a purpose presently described.
16 indicates the pin or shaft, which carries the dial 17 and the plate 9 for Working the tumblers 9, to which plate'Q it is preferably connected by screw-threads, as shown in Fig. I. Said pin 16 snugly fits the sleeve 11, being provided with shoulders 18 19 to engage the shoulders 14. 15, respectively, of the sleeve, as shown. In virtue of the two shoulders be ing provided on the shaft or pin 16 to engage corresponding shoulders in the sleeve 11 it will be seen that a burglar will be effectually prevented from driving the pin or shaft upwardly, and even if a burglar is successful in reducing the diameter. of the outer portion of the pin or shaft to that of the portion of the sleeve between the shoulders 14 he will still be prevented by the shoulders 15 and 19 from driving the pin inwardly,and at the same time the bearing afforded by said shoulders and 19 will permit the pin to turn freely and will thus render drilling of the same very difficult. In order to practically prevent drilling of the outer enlarged portion of the pin 16, and also to prevent its diameter being reduced by other means, I provide the said portion of the pin 16 with three (more or less) pins 20, of chilled steel or other hard metal. These pins are arranged in diametrical holes bored in the enlarged portion of the pin or shaft and intersect or extend at angles to each other, as better shown in Fig. 10, whereby it will be seen that a drill introduced endwise in the shaft or pin will be effectually blocked in its forward movement by at least one of the hard-metal pins.
From the foregoing it will be appreciated that I have provided a construction which will effectually prevent a burglar from driving the pin or shaft 16 and consequently the tumblers inwardly, so as to release the dog 8, and thereby unlock the safe, and that while highly efficient for the purpose stated my improvements are very simple and do not add materially to the cost of the look.
It will also be observed that the sleeve 11 and pin orshaft 16 may be made of standard size and may therefore be placed in looks such as at present in use at a small'cost.
In order to prevent unlocking of the safe in the event of the pin or shaft 16 being forced inwardly and the tumblers 9 being carried out of engagement with the dog 8, I provide a stop 21, which is preferably in the form of a lever and is designed to engage the bolt 7, as indicated by 22. The opposite end of the lever 21 is backed by a spring 23, which has a tendency to force and hold the said lever in engagement with the bolt. Said lever is, however, normally held out of engagement with the bolt, so as to permit of the ordinary free working of the same by the rod 24:,which is connected at one end with the springpressed end of the lever and has its opposite end passed through the casing-plate 5 and impinging against the plug 6. In consequence of this it will be seen that when the pin or shaft 16 and the tumblers are forcedinwardly and the plug 6 is moved before the tumblers the rod 24 and the lever 21 will be released, and the spring 23 will force said lever into engagement with the bolt, so as to effectually prevent the same from being withdrawn from its keeper.
I prefer to employ the lever 21 and its appurtenances for the purpose stated, but I do not desire to be understood as confining myself to the same, as any stop that is normally held out of engagement with the bolt and is released by the movement of the dial pin or shaft and the tumblers in the direction stated may be employed.
I also do not desire to be understood as con fining myself to the details of construction herein pointed out, as many changes may be made in practice without departing from the scope of my invention.
Having thus described my invention, what I claim is I 1. In a safe-lock, the combination of a safe door having a threaded transverse opening and a longitudinal groove in the wall of said opening at the inner end thereof, an exteriorly-threaded sleeve arranged in said opening and having a longitudinal groove at its inner end serving in conjunction with that in the wall of the opening to form a socket and also having its interior diameter abruptly decreased at an intermediate point in its length and the interior shoulder formed by such reduction, a key arranged in the aforesaid socket and adapted to prevent turning of the sleeve and a pin or shaft arranged and adapted to be turned in the sleeve and having a shoulder for engaging the shoulder of the sleeve and also having one'or more inlaid pieces of hard metal between its shoulder and outer end; said pin or shaft being adapted to carry a tum bler-operatin g plate,substantially as specified.
2. In a safe-lock, the combination of a safedoor, a lock-casing at the inner side thereof, a sleeve extending through and fixed in the safe-door and having its interior diameter abruptly decreased at an intermediate point in its length and the interior shoulder formed by such reduction, a rotatable pin or shaft arranged and adapted to be turned in said sleeve and extending into the casing and having a shoulder for engaging the shoulder of the sleeve and also having one or more inlaid pieces of hard metal between its shoulder and outer end, a locking-bolt, a tumbler-working plate on the pin or shaft, tumblers, mechanism controlled by the tumblers for holding the bolt in its locked position, a stop having a tendency to engage and hold the bolt against inward movement, and means for holding the stop out of engagement with the bolt so long as the tumblers are not moved out of their original position, substantially as specified.
3. In a safe-lock, the combination of a locking-bolt, suitable means for holding the bolt in its locked position, astop having a tendency to engage and hold the bolt against movement in a direction to unlock the safe, and means for holding the stop out of engagement with the bolt so long as the means for holding the bolt in its locked position is not displaced or rendered inoperative, substantially as specified.
4. In a safe-lock, the combination of a safedoor, a lock-casing at the inner side thereof, a rotatable. pin or shaft extending through the door and into the casing, a locking-bolt,
' a tumbler-working plate on the pin or shaft,
tumblers, mechanism controlled by the tumblers for holding the bolt in its locked position, a stop having a tendency to engage and hold the bolt against inward movement, and means for holding the stop out of engagement ing against the portion of the casing coincident with the tumblers, whereby the stop will be normally held out of engagement with the bolt and when the tumblers and said portion of the casing are moved out of their original position will be released, substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses.
ANDRE W STEVENSON.
