UNITED STATES PATENT OFFIGE.
' WINFIELD S. CHEDISTER, OF NEWARK, NEW JERSEY, ASSIGNOR, BY MESNE ASSIGNMENTS, TO WILLIAM SOHLEUSSNER, OF BROOKLYN, N. Y.
PERM UTATlON-LOCK.
SPECIFICATION forming part of Letters Application filed December 2, 1891.
To 0. whom it may concern:
Be it known that I, WINFIELD S. CHEDISTER, acitizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Permutation-Locks; 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.
My invention relates to permutation-locks of the type in which the unlocking is accomplished by means of devices whose move ment is regulated in accordance with sound indications; and it consists in providing such locks with simple and accurate means for controlling the permutation appliances. Locks of the same general class have been patented to me under the Nos. 273,466 and 286,903, and under the respective dates of March 6, 1883 and October 16, 1883; but the apparatus is very much simplified by my present invention, the details of which will be fully understood by reference to the accompanying drawings, in connection with the subjoined description.
In the drawings, Figure 1 is an elevation of my lock secured in place. Fig. 2 is a vertical section along line 0c 00 in Fig. 1. Fig. 3 is a rear elevation of my lock removed from its supportj Fig. 4 is a front View of the same with the inclosing case removed and with some ofthe parts shown in section. Fig. 5 is a section along the line y yin Fig. 4.. Fig. 6 is a section along the line 52, looking in a direction opposite to that in which one looks in examining Fig. 4. Fig. 7 is a detail of the click-wheel which forms a part of my invention, and Figs, 8, 9, 10, and 11 are also detail views;
Referring to the drawings by letter, A is the key or handle of my lock, which passes through the wall or support B, to which the lock is applied. Outside the said wall or support and surrounding the said key is an escutcheon C, which is secured in place by screws 0 c a passing through its rim. As shown in Fig. 2, the key has secured to it by a pin or rivet b a disk D, on which is a circular flange d, against which the inner end Patent No. 478,567, dated July 12, 1892.
Serial No. 413,791. (7N0 model.)
of the escutcheon rests, thus preventing the key from being withdrawn while the escutcheon is in place. Behind the wall B the key passes through the inner lock-case E and also throughaslot f in the click-wheel F. The 5 5 click-wheel has on its inner side a ring G. provided with a notch g and supplied with a pin g. It is evident that the click-wheel will turn every time the key is turned. Be yond the click-wheel is a box H, secured to the rear lock-casing E. The ring G on the click-wheel projects into this box. The box does not form acomplete circle,'but is broken at h, as shown in Figs. 4: and 6. Within the box is a series of permutation-ringsland J, each of which is held in place by a separate spring K. Now each of these rings has one or more pins 71 2', which co-operate with corresponding pins on adjoining rings. Thus the ringI has two pins on its outer surface, between which plays the pin g on the ring G. On its inner surface the same ring I has a single pin,which plays between two pins on the outer surface of the ring J. The ring Jhas upon its inner surface a longer pin t", which extends through 75 an opening in the rear case Eand into a slot 0 in a disk 0, which is slitted at one portion of its edge and a part is bent down to form a catch 0. The disk normally rests Within the mouth of a cap P, being constantly pressed 8o outward by a coiled spring p within the said cap. On a ledge r in the said cap is a'pin r, which forms a detent designed to co-operate at the proper time with the catch 0'. It is clear that the movement of the key will give motion first to the click-wheel and then intermediately by means of the co-operating pins to the permutation-rings and the disk 0. Now however far the disk 0 is moved it will not bring the catch 0 into engagement with the detent 1" so long as no inward pressure is exerted upon it, since the spring p serves to keep the disk far enough away to prevent such an operation. If, however, the key is pushed in at the same time that it is turned, its inner end will press the disk 0 inward far enough to cause the engagement of the parts mentioned.
On the outer portion of the case, but within, the said outer portion, I secure a spring 3, mo
which projects out into line with the teeth on the click-wheel and so makes a sound or click when the wheel is turned.
At T,I show the hooks or catches of the look, at U the bolt, at V the spring for throwing the bolt, and at W' the usual tumbler. The latter rests upon the periphery of the permutation-rings or upon one or more of them .until certain slots 0 v in the said rings are brought into a position corresponding to each other and to the notch g in the ring G. This operation of bringing the said notches into the proper position for releasing the bolt is obviously accomplished by certain predetermined movements of the key adapted to operate each ring to the point desired. Such movements are accompanied by clicks,which can be heard by the operator. It is obvious that, given the proper starting-point, the same series of operations will bring about the desired result every time. The objectof the cap P,the disk 0, and the connected parts is, in combination with the other parts described, to furnish the proper starting-point.
In operating the apparatus the first thing todo is to press in on the key (sufficient play for that purpose being given between the wheel F and the box H) and then turn to the right until the catch 0 is brought into engagement with the detent 4''. Then the key is released and turned without pressing in either to the right or left, or both, according to a predetermined code, depending on the number of clicks heard. The cap P is provided at one point with a mark it, which, in combination with a dial M on the outside of the lock-case and in combination with certain radial lines on the said dial, serves as a guide for changing the combination at will. The cap is held in place by screws to to, whose heads catch over the edge of the cap. Ordinarily the arrangement is such that the mark it stands in alignment with the radial line 0, thus calling for certain predetermined movements in order to release the bolt; but the screws to 20 may be loosened and the cap moved so as to bring the mark it into alignment with any other radial lines, as 1, 4, 7, or 11. In that case it is evident that a different series of movements will have to be performed, and that therefore a new combination will have been secured by such alteration.
The number and arrangement of the pins on the permutation-rings and the number of teeth on the click-wheel and on indications on the dial may be Varied at will.
What I claim is-- 1. In a permutation-lock, a permanentlyat-tached key and a click-wheel operated thereby, in combination with a series of permutation-rings and a tumbler controlled by the said rings, the said rings being held within a suitable box and being operatively connected with a click-Wheel, as and for the purpose set forth.
2. In a permutation-lock, a click-wheel and an operating-key, one or more permutationrings operatively connected with the clickwheel, a disk connected with the last ring of the series and pressed outward against the key by a suitable spring, a catch on the said disk, and a detent normally out of the path of movement of the said catch but within its path when the disk is pressed inward by the key, as and for the purpose set forth.
3. In a permutation-lock, an operating-key joined by suitable intermediate apparatus, with a device, as O, carrying a catch, as 0, which engages with a detent, as 4, when the parts are operated under pressure, the said detent being held in an adjustable cap, whereby the movement of the key is susceptible of adjustable limitation, as and for the purpose set forth.
4. In a permutation-lock, a cap attached to the inner case thereof on the outside, the said cap carrying a detent for fixing the startingpoint for the combination and being capable of adjustment, in combination with a scale or dial on said inner case, as and for the purpose set forth.
5. In a permutation-lock, a series of co-opcrating rings held within a box by suitable springs, in combination with a click-wheel carrying a ring capable of entering the said box and connected with the operating-lock key, and a disk carrying engaging devices,
:the said disk being normally held out against the key by a spring and the said key having a reciprocating play, as and for the purpose set forth.
In testimony whereof I have signed my name,in the presence of two witnesses, this 28th day of November, A. D. 1891.
