No. 558,367. Patented Apr. 14,|(1)896.
UNITED STATES PATENT OFFICE.
SYDNEY S. DTI-VAL, OF RICHMOND, VIRGINIA.
PERNIUTATION-PADLOCK.
SPECIFICATION forming 'part `of Letters Patent No. 558,367, dated April 14, 1896.
Application iiled September 23, 1895. Serial No. 5,6 3,364. (No model) To @ZZ whom, t 11m/y concern:
Be it known that I, SYDNEY S. DU-VAL, a
citizen of the United States, residing at Rich-` mond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will en'able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
My invention has for its object to improve permutation-locks whereby it becomes practically impossible to unlock the same unless the person knows the combination, and whereby the lock is improved and simplified in the construction and arrangement of its parts.
The invention is particularly adapted for use in padlocks; also, the invention may be easily adapted for use in locks of other kinds.
In the accompanying drawings I have shown two forms of my invention, one form being applied to a padlock having a swinging shackle and the other to a padlock the shackle of which slides 3 but I do not wish thereby to be limited to the particular form of invention shown so long as the principles of my invention are embodied.
Referring to such drawings, Figure l is a face view of a padlock provided with my invention, the padlock having a swinging shackle. Fig. 2 is a view of the same with the outer face of the case removed. Figs. 3 and et are views similar to Fig. 2, except that they show the parts in rdifferent positions. Fig. 5 is a sectional view taken on the-line 5 5 of Fig. 3. Fig. 6 is a sectional view taken on the line G 6 of Fig. 3. Figs. 7, 8, and 9 are detail views. Fig. lO is a plan view of another form of lock, in which the shackle slides, one of the face-plates of the casing being removed. Fig. Il is a vsimilar view to Fig. l0, except that the parts are shown in different positions. Fig. l2 is a detail plan view of the disk 3.
The casing 25 of the lock may be shaped and put together in any usual or approved As shown in Fig. l, the lock is provided with two knobs 26 and 27, by which the interior operating mechanism is operated. Secured to the face-plate of the lock and arranged concentrically to the said knobs are dial-plates 28 and 29, over which travel pointers 30 and 3l, carried, respectively, by the shafts of the knobs 26 and 27.
The lock illustrated in Fig, l. has a swinging shackle 1,With the notched and beveled end of which engages ahook or dog 2, mounted within the casing. A spring 9 bears against the dog 2 and forces it in position to engage with the end of the shackle whenever it is forced into the casing of the lock. A hook or catch 5 is pivoted to the dog 2, and its end rests upon and engages with a cam or ratchet wheel 8, which is mounted upon the spindle 33 of the knob 27, being held in constant engagement therewith by the spring l0. It will be understood that whenever the knob is turned so as to rotate the ratchet or cam wheel 8 in the direction of the arrow, Fig. 2, the dog 2, if free to be moved, will be drawn out of engagement with the shackle and the latter left free to be moved. Upon the shaft 32 of the upper knob 2G there is mounted a disk 3, in the edge of which there is formed a notch or recess ll'. This disk is mounted op- 'posite to the upper end of the dog or catchbar 2, and the latter is provided with a pin i2, which projects toward the disk. Except when the disk 3 is turned so as to bring the recess l1 in its periphery opposite to the pin l2 it operates to prevent the catch-dog 2 from being moved to release the shackle, as is apparent from an examination of Figs. 2 and 3 of the drawings.
et represents a band which encircles the disk 3, and is held in frictional engagement therewith by a spring 14, so that the band and disk turn together under ordinary circumstances. This band is slotted, as indicated at 13, the slot being so disposed that it may be brought opposite to the recess ll in the disk, and these two, the slot 1l and recess 13, brought opposite to the pin 12. The band is provided with an outwardly-projecting pin 6, the pin being so disposed as not to engage with the pin 12 when the band is turned, as illustrated in Fig. 7 of the drawings. The catch 5 is provided with a pin or stop-piece 7 whichis so disposed as to lie in the path of the pin 6 upon the band whenever the catch is raised toward the disk 3.
Having thus described the parts of the IOO lock, I will now set forth their operation, it being supposed that the parts are in the positions indicated in Fig. 2 of the drawings, the shackle being confined in its closed position.
The person manipulating the lock first turns the lower knob in the direction opposite to that indicated by the arrow in Fig. 2 to the proper point. as indicated by the dial 29, so as to raise the catch into the position indicated in Fig. This brings' the pin 7 into position to intercept the pin C whenever the band carrying the latter turns sufliciently far. The next manipulation is to turn the upper knob in the direction indicated by the arrow in Fig. 23, which turns the disk 3 and the band -i until the pin upon the latter en gages with the pin 7, when the movement of theband is stopped, while the rotation of the disk may be continued. The upper knob should be turned at least one complete revolution, in order to insure the engagement of the pins G and 7. After the pins 6 and 7 have come into engagement and the further rotation of the band -t thereby stopped the disk should continue to be rotated until the recess ll therein is brought opposite to the slot lil in the band. lVhen this position of the parts is arrived at, it maybe indicated by means of the dial. and pointer associated with the upper knob. The next manipulation is to turn the lower knob sufficiently far to permit the catch 5 to fall again into the position indicated in Fig. l, thus releasing the band et. This being done, the upper knob is again turned so as to carry the disk 23 and the band linto position to bring the recess and slot opposite to the pin l2 of the catch bar or dog 2, this position of the parts being indicated by means of the pointer and dial. The parts having been brought to this position, the lower knob is turned in the direction of the arrow, Fig. 2, which will operate to brin g the parts into the positions indicated in Fig. 4, releasing the shackle.
XVhen it is desired to again secure or lock the shackle after the ca tch-barQhas engaged therewith, the catch 5 is raised and the upper knob turned sufficiently far to bring the pins (i and 7 into engagement, which results in stopping the further movement of the band with the disk, after which the disk is turned sufiiciently far to carry the recess ll out of register with the slot I3, after which the shackle cannot be released except by following the steps of the combination as have been heretofore set forth.
In order that the combination may be easily chan ged, I iirst mount the disk upon a reduced portion 36 of the spindle or shaft 32 and hold it in frictional engagement with the shoulder of such `reduced portion by means of a spring-washer 1G, as represented in Fig. S. The spring-washer produces asutlicient friction between the shaft 32 and the disk 3 to cause them to turn together under ordinary circumstanees, and yet when the disk is forcibly held the shaft may be turned therein, as indicated by dotted lines.
In order to change the combination, the parts are brought into the positions indicated in Fig. 4 and there held by means of the lower knob. Vhile thus held the upper knob is turned, its shaft or spindle rotating within. the disk, but without imparting motion thereto. It will be understood that whatever number the pointer indicates upon the dial will thereafter be the number to which it should be turned when the parts are brought into the positions indicated in Fig. 4, permitting the release of the shackle. If desired,
the shaft 32 of the upper knob may be provided with a ratchet-wheel, and such a construction is indicated in Figs. l0 and ll.; but ordinarily this is not required.
In Figs. l() and l1 is represented a form of my invention in which the shackle slides into and out from the lock-easing, and wherein the two ends of the shackle are each provided with hooks by means of which the shackle is locked in place. The parts 2, 3, 4, 5, and S in this lock are substantially the same as the si milarly-numbered parts in the form of my invention already described. The locknowbeing described is provided with a second hook or catch-bar 2', which engages with one end of the shackle, and pivoted to this hook or catch-bar is a hook 5', which is held in engagement with and is operated by the ratchet or cam wheel 8, the hook 5 engaging with one side of the said wheel or disk and the hook 5 with the opposite side. In this form of my invention the band -l.-, instead of being provided with a pin (5, has its edge adjacent to the slot 155 turned outward, as at G', to form a stop, and instead of providing the catch 5 with a pin 7 its end is so shaped' that it engages with the outturned portion (5 of the band when it is desired to arrest the motion of the band relative to the disk 23, and the catch 5 is raised for that purpose. Vhen the parts have been brought to the position indicated in Fig. ll, the shackle is released by turning the ratchet wheel or disk 8 in the direction indicated by thc arrow, and this movement, through the two catches 5 and 5', withdraws the hook-bars 2 and 2 from engagement with the shackle, which is thereby freed and may be removed from the lock. In this form of my invention I have shown the spindles 32 and 33 as being squared at their ends to receive a key by which they are turned instead of having the knobs shown in the other form of my invention.
It will be understood that the bar 2 might be connected with and arranged to operate a bolt instead of engaging with a shackle, the other operating mechanism remaining the same as shown in the drawings, and that in either case the bar operates as alocking-bar. Hence in the claims hereof I wish to be understood, in using the words locking-bar, as referring to the part which is controlled IOC) IIO
by the permutation mechanism, and which when operated serves either mediately or immediately to effect the direct locking or securing action.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
l. In a lock, the combination of the locking-bar having a projecting pin and a permutation mechanism comprising a disk having its periphery recessed, and a band fitted to the periphery of the disk, and provided With a slot, the band being free to be moved about the said disk independently thereof substantially as set forth.
2.
