LOCK.
SPECIFICATION forming part of Letters Patent No. 767,004, dated August 9, 1904.
Appiication iiled April 24:, 1902. Serial No. 104.577. (No model.)
To all whom it may concern.-
Beit known that I, KAROL MUor-Iowrcz, residing at Warsaw, Poland, Russia, have invented certain new and useful Improvements in Locks with Tumbler-Bolts; and I do hereby 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.
This invention has relation to locks, and
has for its primary object to provide a lock employing a series of circular tumblers operated by a key, said lock beingso constructed as to render it extremely dii'licult if not entirely impossible to pick the same; and the invention consists in the novel construction, arrangement, and combination of parts, as hereinafter fully described, illustrated in the drawings, and pointed out in the appendec claims.
In the accompanying drawings, Figure l shows a padlock constructed in accordance with this invention, the front plate and front wall of the lock-case being removed. Fig. 2 is a vertical central cross-section of Fig. 1, showing' the key in position. Figs. 3, 4, 5, and 6 are detached views of the tumblers. Fig. 7 shows a modification in the means for limiting' the motion of the tumblers.
In carrying out my invention, I employ a series of tumblers-say four, as fr r2 fr '/""of circular form, each having' a corresponding slot and arranged side by side inthe cylindrical lock-case?) against the bottom plate c, in the center of which latter is formed a pin Z for the bore of the key. i
In the upper portion of each tumbler an elongated arched slot is cut, thereby forming on the circumference of each tumbler a nose, the four noses being designated f7 f8 f f1, and shoulders fwf limiting the movement. All these noses jointly constitute the bolt, which in the locked state of the padlock is passed through the ears g of the shackle li. As a matter of course the shackle can also open on a hinge-joint, as is common; but in the present instance preference is given to a two-eared shackle inserted into appr0- priate openings in the side wall of the lockcase, for the reason that the latter form of shackle renders it possible in practice to replace this part by other shackles of any dc- The tumblers are provided with slots p pipi, shaped in suoli a manner that in the locked state of the padlock, the passage formed by the safety-guards m, presently described, is not obstructed by the tumblers. The key is not coniined to the one particular form of the bit shown, thus rendering it possible to ininitely vary and modify the disposition of the tumblers. The possibility of modifying the tumblcrs both as regards their form and disposition is provided for by the application in this padlock inside the case at both sides of the keyhole of twosafety-g'uards ou, provided between the bottom plate e and the plate la, covering the tumblers on the front side. These safety-guards, jointly with the appropriate slots in the tumblers, forni a free passage accessible for keys with any form of bit; but said safety-guards being provided with steps or shoulders, whereby said guards exactly correspond in shape to the profile of the proper key, as is apparent from Fig. Q, any key will pass through the passage, but none, with the exception of the proper key, will turn within said passage.
At the right-hand side, as viewed on the drawings, of the passage of the tumblers are provided arched slots Q/ q2 q:i q, intended ori the tumbler turning to give passage to the corresponding step of the safetyguard m. when the tongues or projections s' .s2 s3 s, penetrating into the passage, obstruct same.
In case of an attempt to open the padlock, as described, with a picklock, provided even that one of the tumblers might be turned, its tongues would follow the picklock and not allow the latter to be withdrawn otherwise than on the tumbler being brought back to its initial position. It is evident that the IOO same takes place in opening' the padlock with the proper key. Withdrawn in the open state of the padlock. It is only on the padlock being locked that the key is released. rIhus the bearer of the key has always the certainty that the padlock is locked.
In order to prevent the opening of the padlock by means of a key with an ordinary bit tted so as to answer in height to the shortest step o3 of the proper key, all the tumblers, with the sole exception of the tumbler '/"3, corresponding to that step, are provided on the right-hand side of the passage with sectorslots z5 of a larger radius than the height of said slot.
The movement of the tnmblers in both directions is limited by a stop Z, engaging shoulders f12 f1?, provided on the periphery of the tumblers.
The construction of locks with the circular tumblers can vary with regard to the number of the tumblers as well as with regard to the form and dimensions of the slots provided in them. The stop l, previously mentioned, can be replaced, as shown in Fig. 7, by a spring u, engaging the indentation 'u on the circumference of the tumblers with an audible click, which, as well as the change in the pressure exerted by the key upon the palm of the hand, gives notice of the completely opened or locked state of the padlock.
What I claim, and desire to secure by Letters Patent, is-
l. In a lock, the combination with a casing The key cannot then be provided with va hasp-receiving opening', of a series of tumblers revolubly mounted in the casing, each provided with a slot and with a shoulder or projection, the said projections being adapted to be engaged by bits on an 0perating-key, guard-plates arranged to form a passage for the insertion of an operating-key, said plates being provided with steps or shoulders, as set forth, and an arm or projection on each tumbler adapted to engage a hasp inserted through the opening in the lock-Casing.
2. In a lock, the combination with a casing provided with a hasp-receiving opening, of a series of tumblers revolubly mounted in the casing and provided each with a slot, the said slots being of varying' widths, and each tumbler being provided with a shoulderl or projection, the said projection being adapted to be engaged by bits on an operating-key, guardplates arranged to form a passage for the insertion of the operating-key, said plates being provided with steps or shoulders, as set forth, an arm or projection on each tumbler adapted to engage a hasp inserted through the opening in the lock-casing, each of the tumblers with the exception of the one having the widest slot being provided with a sector-slot t for the purpose set forth.
In testimony whereof I aliix my signature in presence of two witnesses.
