T FFliC CHRISTIAN F. OTTO, OF ZERBST, GERMANY.
LOCK.
SPECIFIOATIO1\T forming part of Letters Patent No. 228,379, dated June 1, 1880.
Application filed October 21, 1879.
To all whom it may concern:
Be it known that I, CHRISTIAN F. Orro, of Zerbst, Germany, have invented a new and Improved Lock, of which the following is a specification.
The invention consists in an improved lock provided with a controlling-latch consisting of a flat bar provided with a pin extending into a slot in the tumbler and with a vertical projection at the end; and in a combination of a spring, a latch-bar, a projection, and a notched bolt, all as hereinafter described.
In the accompanying drawings, Figure l is a front view of the lock, the bolt being within the casing and the front plate being removed. Fig. 2 is the same view, showing the bolt extending into the keeper or mortise, and also showing a strange key introduced into the lock. Fig. 3 is a front view, showing part of the front plate broken off, and also showing a latch-key introduced for releasing the control ling-latch. Fig. 4 is a horizontal longitudinal section on the line a: w of Fig. 3. Fig. 5 is a view of the key, showing the construction of the ward. Fig. 6 is a plan view of the ward of the key. Fig. 7 is a perspective view of the lower part of the key. Fig. 8 is a view of the latch-key.
Similar letters of reference indicate corresponding parts.
A represents the front plate, and B the rear plate, of the casing of a lock, the two being united by screws in the ordinary manner.
The bolt O is provided on one side with the notches D, D and D into which the projection E of the tumbler E, pivoted to the rear plate, B, by means of the pin F, passes, and the notch G, into which the rear part of the latch-bar H passes. On the other side it is provided with the two large notches I and 1 into which the movable part of the ward passes, and with the notches J J and J into which the projection K, on the lower end of the tumbler L, pivoted to the rear plate, B, by means of the pin L, passes.
The bolt is guided by the top plate, M, and by a bar, N, attached to the rear plate, B, and provided with the recess N for the bolt and the recess N for the tumbler L.
A spring, 0, acting upon a pin, 0, on the tumbler L, presses the same toward the bolt 0. A spring, D, presses the tumbler E toward the bolt, and a spring, Q, which may be arranged as shown in the drawings, or in any other suitable manner, presses the latch-bar H downward.
The tumbler L is provided with a small inclined slot, l, into which a pin, 71 attached to the latch-bar H, passes. One end of thelatchbar H is provided with a vertical projection, H, which catches behind the edge of N when the latch takes in the notch G in the bolt.
The main key It has a ward consisting of the fixed part S and a movable part, T, which may be almost entirely rotated on the pin U, provided with a check-pin, U. The pin U is of less diameter than the shank of the key. but the sleeve of the rotating part T is of the same external diameter as the shank, as is shown in Figs. 5, 6, and 7.
The operation is as follows: The bolt 0 being in the position shown in Fig. l, the key It is introduced and turned in the direction of the arrow a. The movable part T of the ward rotates until it rests against the lug W, between the two notches I and I as is shown in Fig. 1. The fixed parts of the ward rotates with the key, presses against the tumbler L, and moves the same in the direction of the arrow 1), thus disengaging the projection K from the notch J As soon as the fixed part of the ward is in the position shown in Fig. 1, then the pin U has rotated sufficiently to catch on the shoulder of the movable part T, and causes the same to rotate with the rest of the key, and presses against the tumbler E, and thus disengages the projection E from the notch D. The part T then presses against the upper edge of the notch I and raises the bolt 0. As the key turns on the parts S and T will withdraw from the tumblers L and E,
respectively, and the projection E will pass into the notch D and K will pass into J The next rotation of the key will raise the bolt the same distance, and it will be in the position shown in Fig. 2.
It is evident that the lock will operate in the same manner if only one turn of the key or more are required, and I do not limit myself to the construction shown, but may arrange the lock so that one or more turns of the key are required. To draw the bolt back the key is turned in the opposite direction and the same movements occur, but in reverse order. The movable part T, which is longer than S, passes below the tumbler L, and S passes below the tumbler E.
If the bolt is in the position shown in Fig. 2, and the key Y, that does not fit to the lock, is introduced, the ward of the key will press the tumbler L in the direction of b, which will cause the latch-bar H to move in the same direction and the rear part to enter into the notch Gin the bolt 0, and the projection H to pass beyond the end of N. As the spring Q presses the latch H downward the projection H will pass down as soon asit has passed over the edge of N, and will remain in this position, thus securely locking the bolt, as shown in Fig. 3. The bolt cannot be moved by any key (not even the key belonging; to the lock) until H has been released. This can be done in many different ways; but the simplest would be to use a key, Fig. 8, which catches below the curved plate V, attached to H, and raises them both until the projection is above N. As the pin it passes through the slot l in the tumbler L the spring 0 will be able to press H in the direction of d as soon as H is raised above the upper edge of N, and will thus release the bolt, so that the proper key can be used. The owner of the proper key is thus enabled to detect if a strange key has been used,and can make the lock inoperative himself upon leavin g the house, so that a person with the proper key cannot open the lock unless he knows the arrangement of the latch device, and this can be arranged so that none but the owner knows it.
It is evident that by varying the lengths of the parts of the ward and by varying the number of fixed and movable parts of the ward and the number of tumblers, any desired number of variations of this look may be produced; and I do not limit myself to the use of one movable part of the'ward andto two tumblers, but may provide more than one and any suitable number of tumblers.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The lock-bolt, in combination with a controlling-latch consisting of a flat bar, H, provided with a pin, h, extending into the slot 1 in the tumbler L, and with a vertical projection, H, at the end, as herein described, and for the purpose set forth.
2. The combination of the spring Q, latchbar H, provided with the projection H, and the bolt 0, provided with a notch, G, as herein described, and for the purpose set forth.
CHRISTIAN FRANZ OTTO.
