2 Patented Nov. 17, ,832,61 A.. UNITED STATES PATENT OFFICE WILLIAIVI JULIUS PATAKY, OF BROOKLYN, NEW YORK KEYLESS LOCK Application filed December 17, This invention relates to new and usefulim provements in a keyless lock. The invention has for an object the provi sion of a keyless lock which cannot be opened by feeling when the cutouts are in line with the bolt. Generally, keyless locks are con structed with bolts which may be slightly moved when the lock is in the closed condi tion and the combination moved very care fully so as to feel when the cutouts come in line with the bolt, and the lock may be opened without the operator knowing the combina tion. This invention proposes the provision of a plurality of blind cutouts in the combi nation so as to mislead attempts at feeling. The invention has for a further object the provision of a keyless lock which is char acterized by a plurality of lock rings with in terengaging parts so that they may be readily stacked. This is of great convenience in changing the combination of the lock in that the lock rings interengage and can be held in stacked condition without much difficulty. It is a still further object of this invention to provide a keyless lock which is character ized by a boit bent into the shape of an in verted U with the arms of the bolt of different diameter so as to engage into the lock one way only and to double the possible combina tions of the lock. A still further object of this invention is to arrange the lock rings with circular ridges at their top ends engageable in corresponding recesses at the bottoms so as to prevent the insertion of a knife or tool between the rings for possible feeling of the cutouts. A still further object of the invention is the provision in a keyless lock of means for preventing turning of the lock ring unless the bolt is completely in its locked place. For further comprehension of the inven tion, and of the objects and advantages thereof, reference will be had to the follow ing description and accompanying drawings, and to the appended claims in which the va rious novel features of the invention are more particularly set forth. In the accompanving drawings forming a material part of this disclosure:- Serial No. 02,921. Fig. 1 is a side elevational view of a lock constructed according to this invention. Fig. 2 is a plan view of Fig. 1. Fig. 3 is an enlarged sectional view taken on the line 3-3 of Fig. 2. Fig. 4 is a perspective view of one of the lock rings. Fig. is a perspective view of a shank member used in the lock. Fig. 6 is a fragmentary sectional view taken on the line 6-6 of Fig.. Fig. 7 is a view similar to Fig. 3, but illus trating a modified form of the device, and Fig. 8 is a plan view of one of the lock rings used in Fig. 7. The keyless lock has a shank member 10 with a bottom flange 11. A plurality of lock rings 12 are stacked one above the other and superimposed upon the flange 11 and rotatively mounted upon the shank 10. A detachable cover 13 is mounted upon the top of the shank and overhangs the top lock ring 12 so as to prevent the removal of the lock rings. A bolt 14 is extended through the cover 13 and in between the shank member 10 and the lock rings 12. The shank member 10 is circular in hori zontal cross section. The lock rings 12 are formed with inwardly projecting top ledges 1. These ledges are turned down along the outer corners so as to provide top ridges 16, and at the bottoms the rings are of such a diameter so as to fit upon the ridges 16. This is very clearly shown in Fig. 3 where the rings are shown interengaging each other. It should be recognized that the ridges 16 serve to rotatively connect the rings with each other and to prevent the insertion of a knife or tool between the rings, and also to hold the rings in a stacked position, the latter case being particularly true when the rings are removed from the shank. The cover 13 is recessed on its bottom side so as to receive the ridge 16 of the top ring 12. The detachable cover 13 is in the form of a disc which has a central downwardly pro jecting stem 17 threadedly engaging into the top of the shank 10. When the lock is in the closed position, the bolt 14 prevents rotation of the cover and holds the lock closed as a

The arms of the bolt ends at 33 in a cavity within the fange 11 beneath the shoulder are of different diame and has one of its arms extended adjacent ters, as may be clearly seen in Fig. 3, so that the longitudinal member 26 and pivotally the bolt can be placed only one way into the connected to it by a pintle pin 34.

Each of the rings 12 are be withdrawn. since all of the cutouts 19 and graduated on their Outer face with linerals 20 of the different rings 12 are in line with from one to ten. For each one of these nul the arms of the bolt 14. To lock the lock, it merals, there should be, one blind critoit 22 is merely necessary to rotate all of the rings or one of the real cutouts as 19 or 20. A start ing line 23 is formed upon the periphery of the flange 11 so that the rings may be placed relative to each other and in a certain posit tion relative to the shank 10. The shank () is formed with longitudinal cutouts. 24 and 2 for allowing the passage of the arms of the bolt 14. The bolt, is so positioned that half of it lies, within the cutouts 24 and 2, '' in the other half extends beneath the ledges 1 of the rings 12. A means is provided for preventing turn ing of the locking rings 12 when the bolt T4 is not in its complete inner position. This means is of advantage in that it is impossi ble to hurriedly close the lock and close it incompletely by not inserting the holt its full distance, and then turning the rino's 12 so as to hnl? the bolt in the locked position. If not for this means, the name of possi ble combinations of the lock would be re duced if it were closed in a condition with the bolt artially extended. The means mentioned in the previous par agraph comprises a longitudinal, ember 26 slidably mounted in a longitudinal slot 2. formed in the shank 1 (). The longitudinal member 26 extends the complete length of is formed with a plurality of vertically milled lines 30 engageable in corresponding 12 so that the ledges 1 ride into the crit o; its 21 in the lot. Now the bolt cannot be withdrawn. To open the lock, it is neces sary to place the rings back into their initial position and this can he done by knowing the combination and setting the rings as di 'e (fe?l by the ninet': is on their olter faces and by the indicating line 23. When the rings have been set so that the bolt 14 is free, the latter element may be drawin out. In the event that the operator wishes to change the combination of the lock, he need only remove the detachable cover 13 when the bolt 14 is out and then slip all the rings 12 off as a complete unit in stacled po sition. The the rings should be taken apart and their relative positions changed. For example, the bottom ring may be placed on the top. and some intermediate rino at the bottom. The cil to its 19 it ind 20 of the dif ferent rings are arranged a diacent different numera's on the peripleries of the rings and it will be recognized that such changes change the combination. In the modified form of the device illus trated in Fig. 7, a means has been shown for holding the bolt of the lock in its opened condition. The bolt is indicated by reference numeral 37 and distinguishes from the bolt in the preferred form in that its top is bulged out and in that one of its arms. indicated by reference nuineral 38, is longer than the other arm, indicated by numer all 39, and the longer arm is formed near its end with a peripheral groove 40 com municating with a longitudinal groove : 31, rt)

A have the same condition as far as this feature peg 42 projects from the is concerned as we have in the form of the cover 18 and engages in the longitudinal groove 41. This construction allows the bolt device illustrated in Figs. 7 and 8. to be drawn out until the While I have illustrated and described my groove 40 reaches invention with some degree of particularity, the pin 42 and then the bolt may be swivelled around upon the arm 38.

This the scope of the appended claims. is accomplished by forming a plurality of Having thus described my invention, what radial slots 43 in the top ridges of each of I claim as new, and desire to secure by United the lock rings, these slots being so spaced as States Letters Patent is:- to correspond with one indicating number 1.
