GEORGE WILLIAM DILLAVVAY, OF MUSOATINE, IOWA.

PERM UTATlON-LOCK.

SPECIFICATION forming part of Letters Patent No. 641,501, dated January 16, 1900.

Application filed April 24,1899- To aZZ whom, it may concern.-

Be it known-that I, GEORGE WILLIAM DIL- LAWAY, of Muscatine, in the county of Muscatine and State of Iowa, have invented cer* tain new and useful Improvements in Permutation-Locks; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification. I This invention is an improvement in permutation-locks; and it consists in the novel combinations and constructions of parts hereinafter claimed.

The accompanying drawings illustrate the best form of look now known to me embodying my invention; but as the form of the look when the invention is once known can be varied in details I do not herein limit myself to the specific constructions of lock shown in the drawings and hereinafter described.

Referring to the drawings, Figure 1 is a top plan of the lock, partly broken away. Fig. 2 is a rear view thereof, partly broken away. Fig. 3 is a detail vertical section on line 3 3, Fig. 2. Fig. 4 is a similar vertical section on line 4 4, Fig. 2. Fig. 5 is a similar section on line 5 5, Fig. 2. Fig. 6 is a detail rear perspective. Fig. 7 is a detail of the handleguiding device. Fig. 8 is a detail top plan view of the tumbler-holder and tumblers. Fig. 9 is an enlarged perspective view of one of the tumblers. Fig. 10 is a detail sectional view of a modification.

Referring to the drawings, A designates the tumbler case or holder of the lock, which, as shown, consists of a rectangular block provided on its upper surface with two parallel series of tumbler guide-fingers a a, separated by a longitudinal groove (L The fingers Ct are preferably beveled on their front edge, so as to facilitate entrance into the slots between the fingers, and in each slot, between the fingers, is placed a reversible tumbler B, which in the construction shown is rectangular in form, so as to fit easily in one of the slots between the adjoining fingers, and each tumbler is provided on its upper edge witha notch b, which notch is nearer to one end of the tumbler than the other and divides the upper surface thereof into a short or idle portion I) and a long or looking portion b Phe Serial No. 714,230. (No model.)

idle portion may bear a number or letter or other indicating character corresponding to the number or-indicating character of the slot in which it is to be placed-11. 6., indicating characters may be marked 011 the block A beside the slots, or, preferably, may be made on a plate A,overlying the fingers a-and assist ing in retaining the tumblers in the grooves. A plate A may also be placed across the fingers a for the same purpose. If the tumblers are set so that all the locking portions b are in line with the front row of fingers a, as indicated in Fig. 3, the notches b coincide with the groove a between the series of fingers a a, and when in this position the tumblers stand normally in non-lockingpositionthat is, not in position to prevent the unlocking of the device. If any one or more of the tumblers B are reversed, so that the locking portions 11 are in line with the fingers 00', parts 19 will then project into the groove a as shown in Fig. 8, and such tumblers will then be normally in looking position-that is, they would obstruct the groove a and prevent the descent of the lockin g bar or plate 0, hereinafter referred to. It is obvious, therefore, that any number of the tumblers B may be made the active or normal lockingtumblers by reversing them or turning them around so that the parts I) are in the rear row of fingers a.

The locking bar or plate 0 stands normally over the groove a and until this plate can enter said groove the bolts will be looked, as hereinafter described. Of course so long as any locking portion 19 of the active tumblers projects into the groove a the locking-plate cannot enter the groove.

When any of the tumblers are in active looking position, as described, before the plate can enter the groove a it is necessary to push such tumblers out of the way until their notches I) register with groove 0L2, and this is accomplished by means of a selector and pusher, which in the construction shown consists of a pin D, mounted on a slide D, guided in a slot E in a hinged or rocking plate E, that is pivoted just in front of the block A, the slot E extending horizontally in front of the line of tumblers, as shown, and by moving the slide D back and forth pusher D can be brought opposite any tumbler in any slot of the block, and then by pushing plate E forward the pusher D is projected into the slot against the tumbler therein and pushes the tumbler backward, as indicated in Fig. 5. The slide D may be shifted by means of an arm D attached to a gear D pivoted on a suitable stub-shaft D above the plate E, said arm having a slot (1, engaging a pin d on the slide, so as to permit the arm to reciprocate the slide back and forth as the gear D is oscillated. The gear D as shown, is operated by a pinion f, slidably but not rotatably mounted on a shaft F, which is connected to a conical plug F, that has a cylindrical head F fitting in a cylindrical bore F in the wall of the safe or casing of the lock, the inner portion of the plug being tapered, as shown at f, and the inner portion of the bore in which the plug is contained being also tapered, as shown at F so that if said plug is pushed too far inward it will jam in the bore, so that it will be impossible to force it inward through the bore. The face of this plug at the exterior side of the wall of the lock (or safe-door to which it is applied) is connected to the stem g of an operating-handle G, which may be pushed outward by a spring G, interposed between the wall of the safe and a disk H on the stem g, as shown in Fig. 5. This spring normally projects the handle G and disk l-I outward, thereby pulling the plug outward with it, the normal position of the parts being such that the face of the plug will be flush with the face of the safe.

The spring G and disk H are inclosed in a conical casin g h, resembling an ordinary permutation-lock indicator, and on the handle G, exterior to the disk H, is a conical plate G the edges of which are tapered in conformity with the taper of the casing h. The plate G may be kept close to casing h by means of a band It on the casing, as shown, so that the plate can rotate with the handle, but has no longitudinal movement therewith. The casing 7L or plate G or both, may be provided with indicating-marks, as shown, there being at least one mark for each tumbler in the lock, and these marks being so located that the operator can by turning the handle G until a certain point on the plate G registers with some particular mark on the casing h bring the pusher D opposite the slot containing the tumbler bearing the same mark. He can then by pushing the handle inward cause the pusher to engage with such tumbler and push the latter inward.

In the construction shown the inner end of the shaft F is loosely connected to a hinged bar f which is hinged at its upper end, as shown at f while its lower bifurcated end f looselyengages or is connected to the tilting plate E, so that when the handle G is pushed inward the plate E is rocked forward, throwing pusher D into one of the slots and pushing back the tumbler therein, as is evident from the drawings. To enable this action to occur, the shaft and handle G are capable of both rotary and longitudinal movement, the handle G being made angular, so that it will rotate the plate G but can slide freely therethrough. The disk H is fixed to the handle G, so that it partakes of both movements thereof, and this disk is provided with a controlling-finger H, which is adapted to enter one of a series of perforations H in the face plate of the lock or door to which it is attached, so as to prevent the rotation of the shaft F and handle Gwhen the lock is pushed inward and to also prevent the latter being pushed inward until the pusher D has been shifted into exact position to engage with some one of the tumblers.

The locking-plate O in the construction shown is preferably suspended vertically above the slot 0, by means of hinged arms 0. One of said arms C engages the bifurcated end I of a pivoted bolt-lockinglever I, which is oscillated into unlocking or bolt-releasing position by the entrance of the locking-plate into the groove of and is thrown into locked position so long as said plate 0 is lifted and kept out of the groove. Of course this plate remains in lifted position orout of the groove so long as any locking-tumblers are in locking position or will be kept out of this groove if any of the non-locking tumblers are improperly shifted in their slots, as might be done by any one attempting to tamper with the locks, for if any one of the non-locking tumblers be shifted backward it will prevent the entrance of the locking-plate into the groove even should the proper tumblers (which had been adjusted to normally keep it out of the groove) be shifted into unlocking position, because it is necessary with my look not only that the locking-tumblers be shifted into unlocking position, but that all the other non-locking tumblers remain in their normal non-locking position. In other words, in my look a certain number of tumblers can be selected as the normal locking tumblers and will normally stand in position to prevent the entrance of the locking-plate into this groove,while the remainingtumblers will normally stand in position to permit the plate to enter into the groove. This locking-plate, therefore, cannot enter the groove until every one of the locking-tumblers are moved into unlocking position, and if any one tampering with the lock displaces any of the non-locking tumblers they will prevent the entrance of the locking-plate into the groove, and although he may subsequently move all the normal locking-tumblers into unlocking position, yet he will not be able to open the lock; but before it can be opened it will be necessary to return all the non-locking tumblers to non-locking position and the locking-tumblers to locking position. This, however, can be easily accomplished by means of one certain setting-tumbler, (designated as B in the drawings,) which setting-tumbler is provided with a notch Z) like the others, adapted to register with the groove (F, but is provided with a rearwardly-projecting finger B which is adapted to engage an oscillating lever or levers J, pivoted on the top of block A in rear of the tumblers, said levers being adapted to engage with the push-plate J, which lies in rear of all the tumblers and will be pushed back by the displacement of any one of them, as indicated in Fig. 5. If, therefore, a mistake has been made in pushing any one of the tumblers, the operator can shift the pusher D in position to engage the setting-tumbler B, (determining this by a known mark on the index-plate G and when tumblerB is pushed backward its inner end operates the levers J, which in turn push plate J forward toward the fingers a, throwing all the tumblers back into theiroriginally-set position. The first tumbler that is thereafterward displaced will force the plate J backward, and by so doing will cause the levers J to return the tumbler B to original position. The plate J may be guided by pins J attached to block A and projecting through perforations in the plate, as shown.

As a further precaution against the descent of the plate 0 and as a means of providing a day-lock, I provide one of the tumblers with positive means for controlling the rise and fall of the plate 0, even if all the other tumblers be in unlocked position, so thatit will be necessary to actuate this particular tumbler after the permutation locking-tumblers have been displaced. For this purpose I employ the tumbler B This is. provided with an upstanding finger 19 which (when the tumbler B is in normal position) stands above and across the slot a and obstructs the entrance of the locking-plate. The front end of this finger b however, is beveled, as at 12 and leads into a notch 6 which is adapted to register with groove a when the tumbler B is moved backward by the pusher D and will permit the descent of the locking-plate it the other tumblers are all in proper unlocking position at the time. This tumbler B is, moreover, provided with a rearwardly-projecting finger B which when the tumbler is pushed inward engages the upturned end k of abent rod K, that extends forward beyond the hinged plate E and has an upstanding finger 7a, which normally impinges against the front edge of this plate. When the tumbler B is pushed backward by the pusher D, it moves rod K backward by the engagement of projection B with arm k, causing arm 76' to fol low up the plate E; but when plate E is pulled back to normal position by spring G and intermediate connections, thereby retracting the pusher, it causes arm 76' to pull rod K forward, and it,through arm it, pulls tumbler B forward, and then the bevel b on the tumbler rides against a bevel C on the locking-plate and forces the latter out of the groove a and holds it up out of the groove, the plate resting on arm b until the tumbler B is again displaced. By this means the locking-plate is positively raised, and in so doing the boltlocking devices are thrown in position to positively prevent the unlocking of the bolts.

As shown, the locking-plate 0' stands over slot a and is weighted, as at 0 so as to cause it to drop by gravity into the groove 0, when permitted but,if desired,the tumbler B could be replaced by a tumbler 13 (see Fig. 10,) which is provided with an inclined groove B", engaged by a pin 0 on the locking-plate, so that this tumbler would move the lockingplate positively into and out of the slot.

For convenience the tumbler carrying block A may be made removable, so that it and the tumblers can he slid out from under the locking-plate to permit the tumblers to be set or rearranged at will and adjusted into normal looking or unlocking position, according to the permutation -sign desired. As shown, the ends of block A are formed with dovetailed grooves A, engaging dovetailed guides of, secured to the support for the block, and when slid into position the face of the block abuts against a plate A'', by which the tumblers are all kept in alinement and prevented from going too far forward. The block may be detaohably secured in position by means of the lever L and slot L or any other suitable attaching devices. The bar K may be detachably secured in a groove a in the end of the block A, as shown, if desired.-

When the tumblers are in normal unlocking position, Fig. 3, the index-marks thereon, on the portion b thereof are covered by the plate A but when they are adjusted to normal locking position the index characters thereon appear on the portion b projecting from beneath said plate, so that by noting the characters appearing on the projecting ends of the tumblers the locking-tumblers will be known and can be selected by the index and handle G. In unlocking it is not necessary thatthe unlocking-tumblers be selected or shifted in any particular order. It is necessary, however, that all the lockingtumblers shall first be pushed back before the day-lock tumbler B is pushed back, and it is further necessary that none of the other nonlocking-tumblers shall have been disturbed. To look the safe, the handle is turned until the index registers with a mark corresponding to the setting-tumbler B, and then is pushed back, whereupon all the tumblers are thrown into normal position by the plate J, and the safe cannot be unlocked until they are properly displaced under conditions just recited. However, if it is frequently desired to open the lock during the day after it has been once opened the setting-tumbler should not be operated, as the other tumblers will remain in unlocking position until the settingtumbler is pushed back; but the tumbler B will then serve as the sole and temporary means of locking the plate.

To change the permutation, the block A, with the tumblers, can be removed from its position and any number of tumblers desired can be made locking-tumblers (which it will be necessary to shift before the lock can be opened) by simply reversing them in their slots or by turning them so that the parts 6 are in rear of the groove a and any tumblers that are not to be locking-tumblers are left in position or turned so that their parts 13 will be in front of the groove a It will thus be obvious that the tumblers can be changed from normal looking to normal unlocking position by simply reversing them or turning them around endwise in their grooves. Suppose, for example, that the permutation was U S X. The tumblers U S X would be placed in their slots so that the parts 12 were at the rear of the groove a and then when the tumblers are in normal position it will be impossible for the plate 0 to enter the groove until each one of these tumblers U S X have been pushed backward by the pusher and none of the others disturbed. These three tumblers may be pushed back in any order, and after they are pushed back it is then necessary to push back the day-lock tumbler 13 whereupon the plate can descend. The tumbler B can then be used also as the day-lock, or by pushing back the setting-tumbler B the entire combination will have to be operated to unlock the safe.

I have simply given an instance of a selection of three tumblers for the permutation; but obviously any number might be employed, as desired; but I do not consider it advisable to select a very large number of tumblers, because of the double safety feature of the lock-to wit, the displacement of a wrong tumbler necessitating the resetting of the entire set before it can be opened.

I have shown the tumblers arranged in a straight series and operated indirectly from the handle. In some forms of lock the pusher might be connected directly with the handle and operated directly thereby and the tumblers may be arranged in a curved series vertically or horizontally or concentric to the pusher, or in simple forms of lock the handle might be attached directly to the pusher and slide in a groove in front of the tumblers.

It is obvious that the invention is capable of modification and embodiment in various forms within the scope of my invention and embodying the essentials thereof, and therefore, While I consider the form which I have illustrated the best now known to me, I do not wish to confine myself to the specific construction shown, but shall undertake to here disclose the many modifications of the device which have occurred to me or may occur to others when the invention is make known to them.
