HENRY GROSS, OF TTFFN, OHIO.
IMPROVED PERMUTATION-LOCK".
Specification forming part of Letters Patent No. IGLGQ, dated March 29, lim).
To all whom may conceive.-
.Be it known that I, HENRY G'Ross, of Tifiin, in the county of Seneca, and in the State of Ohio, have invented new and useful Improvements in Permutation Bank-Locks; and/I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
The nature of my invention consists in the construction and general arrangement oi a permutation bank-lock.
In order to enable others skilled in the art to which my invention appertains to make and 2 is a plan view of the same, part in section,
showing the manner of securing the arbor and dial. Fig. 3 is a vertical section of the cam- Fig. l is a perspective of the eccentric `which holds the centers of the wheels stationary. Fig. is a4 side View of the wheel with movable center. vFig. G is a front view of the dial. Fig. 7 is avertical section of Fig. 5, and Fig. 8 is aperspective of the dog or rack-slide which operates the bolt.
A represents a section ot the safe-door to which the lock is attached7 and through which the arbor B passes. This arbor is made in two parts, as seen in Fig. 2, the inner part having at its outer end two holes, into which two pins, a a, on the inner end -of the outer portion of the arbor are placed. The outer end of the outer part of the arbor B forms the knob and the dial (i, which is secured to the door A by an annular ring, I). The object of making the arbor B in two parts is that if burglars should break oft the dial they would still fail to get inside the lock, and the dial could be readily replaced with another of si1nilar make, and the lock be unlocked on the same combination. rlhe outer circumference of the dial is divided into one hundred equal parts, as seen in Fig. G.
On the arbor B, within the lock, are loosely placed three wheels, E. The center F of each of the wheels E is movable-that is, so arranged in a circular hole through the wheel that the center can be turned independent of This is accomplished by having a plate attached to the center F, so as to 'formv a groove around its outer circumference, in which a tongue or lip on the inner circumference of the wheel E iits, Vas seen in Fig. 7. The center F is held stationary in the wheel E by means of two eccentries, b I), pivotedin a recess on the wheel, and acted upon by a spring, d, so as to press them against the outer edge of the center and hold it stationary. That portion of the eccentrics I b which bears against thecenter F is corrugated, so as to insure the holding of the center `in position. Arms or handles attached to the eccentries I) b meet opposite a groove or recess, e, in the side ot the wheel, said groove opening from the outer edge of the wheel, as seenin Fig. 5. A pin, i, is passed through the center F, projecting on both sides, as seen in Fig. 7- Three of these wheels are placed loosely on the arbor B, and on the inner end of the same is secured a wheel, G, which has a cam-Hange, f, along its outer periphery. At .la certain point on this wheel is a slot or notch, h, on each side of the flange j'. The fiange f moves the dog orrake-slide H to either side, keeping the slide passing over the slot, so that it is rubbing over the unslotted portion of the wheel at all times, which prevents eX- perts from picking the. lock, either from sound or feeling, as there is an equal friction at all times and in all parts. On the front sidethat is, the side toward the wheel E--of the wheel G- is a pin, o, which, when the arbor is turned in either direction, catches on the pin i of the first wheel E. This in turn catches and turns the second, and the second turns the third, or the one nearest the outside.
On top of the wheels G and E E rests the dog or rake-slide H, which on its under side is provided with pins It k and three lugs, m m, all placed in a line, the two pins k L being just sufficiently apart to allow the flangef to pass between them. On the outer edge of the slide H is secured a plate, n, having a projection alongside of the outer piu, 7.1. If the wheels Gl and E Fare brought so that the slots 7L and c c come on a line .just under the pins 7tand lugs my, these will 'fall into. the said slots, and consequently the slide moved to or fro, so as to lock or unlock the lock.
t c At the rear end of the slide II in the lock is placed a stop, J, which prevents the slide from moving back, except when it has fallen yas seen in Fig. 17 in Which a pin on the lever I is placed, so that when the slide H is moved back the bolt will be raised, and vice versa. The upper end of the bolt is holloWed out and strikes against a pin in the lock-box, so that it cannot be raised too far. The lower end of the bolt is also cut out, as shown by dotted lines in Fig. 1.
Supposing the lock has been set for the combination 39 21 58, then to unlock the same turn the knob three or more times around, stopping when No. 3977 is againstthe mark c on the annular ring D, this mark being on a line With the pins k k and lugs m m when it is locked. This will place the Wheel E nearest the outside in proper position. Then turn t'o right, passing 39 twice, and stopping When 2l7 comes opposite the mark c, which places the middle wheel in position. Then turn to' the left again, passing 21 once, and stop 4when 5S is against the mark c, which places the last Wheel in position. Then turn slowly to the right until the slidey H drops down and unlocks. For the purpose of changing the combination, there is placed under the Wheels G and E E a bar, M, pivoted to the lock-box, one end of which is attached to and operated by the lever N. By turning this lever down, the opposite end of the bar M is pressed up against the Wheels, and this end of the bar being provided With lugs s s, said lugs enter the grooves e e in the Wheels E E, if
these are properly placed. Then to change the combination proceed in the same manner as for unlocking, but let the numbers come op- 'posite the mark S on the annular ring D,
which mark' is on a line with the lugs s s. When the Wheels E E are placed in proper position, turn the lever N down, which will force the lugs s s into-the recesses or grooves c e, pressing on the arms of the eccentrics b b, and consequently releasing the centers FF. When this is done, the lock can be set with any combination desired at the letter S, but unlock from letter C.
Having thus fully described my invention, WhatI claim as new, and desire to secure by Letters Patent, is-
1. The Wheels E E, 'with slots e e cut upon but one-half of th'e periphery of the Wheels, and with eccentrics b b, in combination with the slide H, having pins 7c and lugs m, all s ubstantially as set forth.
2. The cam-Wheel G, With bent iiangef and notch h for receiving Ithe slide, substantially as and for the purposes herein set forth.
3. The slide H, With pins k 7c, lugs m m, and double hinge p, substantially as and for the purposes herein set forth.
4. The combination and arrangement of thel arbor B, dial C, Wheels E E, cam-Wheel G,Wiih its bent ange f, slide H, bolt L, and arm M, all constructed as described, and operating substantially in the manner and for the purposes set forth. I
In testimony that I claim the foregoing I have hereunto set my hand this 5th day of August, 1869.
HENRY GROSS.
