LOCK.

Application filed February 20, 1915.

To all whom it may concern; 1

Be it known that I, EUGENE Krns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in 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. 7

This invention relates to new and useful improvemcntsin locks and the principal object of the device is to provide a lock where in the necessity of providinga. key is eliminated.

Still another object of the invention is to provide a lock which cannot be opened eX- cept'by the persons knowing the proper combination.

Still another object of the invention is to provide a lock having a plurality of movable stops which are adapted to be adj usted" to form various combinations and in which it is possible for the user to readily change the combination, thus avoidingany possibility of persons becoming familiar with the single combination.

Still another object of the invention is to provide a lock wherein the possibility of changing the combination unless the lock is opened is eliminated.

. A further object of the invention is to provide a device which is readily applicable to padlocks, door looks or any other type of lock.

lVith these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a side view in elevation of a lock constructed in accordance with this in vention.

Referring to the drawings, the numeral 1 designates the casing of the device comprising the main compartment 2 and the extension 3. The outer Wall 4 of the casing is provided with the lock bolt opening 5, the latch opening 6, the stop block adjusting bar opening 7 and the opening 8 through which the stop block carrier is adapted to be removed for changing the combination. The sides of the casing are provided with alined openings through which the shaft 8 for the latch extends and this shaft 8 is provided at its outer end with the usual knobs 9 for controlling the movement of the latch. A similar pair of alined openings is formed near the lower end of the chamber or body 2- and are adaptedto receive the shaft 10 which controls the operation of the lock and carries at its outer ends the knobs '11 by which the same is turned.

Formed within the casing is a suitable supporting wall 12 for the stop block carrier and immediately above the wall 12 isa supporting wall 1-3 forthe lock bolt and the lock block. A suitable wall 14 is formed at a point above the wall 13'and is adapted to form a guide for the receipt of the lock bolt. Extending upwardly in close proximity to the front wall 4L of the casing and between the wall 14: and the upper wall thereof is a vertical wall 15 provided with an aperture 16 alining with the aperture 6 for the reception of the latch. A suitable wall 17 extends upwardly from the bottom of the casing to a point slightly below the open ing 7 and has attached thereto the block 18 provided with the reduced extension 19 having the opening 20 through which the ad justing bar for the stop block is slidable.

Slidable through the opening 6 in the wall a and through the opening 16 in the wall 15 is the latch 21 provided with the bevel face 22 and formed integrally with the latch and extending inwardly therefrom is the extension .13 which is slidable between the fingers 24 formed integrally with one of the side walls of the casing 2. This extension is provided with the notches 25 and seated in the notches are the inward ends oi? the ingers 26 formed at the ends of the arms 27 of the latch operating member 28- which is formed with the outer extension 29 projecting from one of the side faces of the arms 27 as clearly shown in the drawings. This latch operating member is adapted to be engaged by the oppositely extending arms 30 which are secured to the shaft 8 and carried on a suitable sleeve 31 as clearly shown in Fig. 3.

Slidable through the opening 5 in the wall 1 and resting on the wall 18 is the lock bolt 32 provided with the reduced extension 33 which is formed with a series of stops or shoulders against which the lock block 35 abuts. This lock block is provided with a plurality of shoulders which conform to the shape of the shoulder 841 and the rear end of the block engages the rear wall of the chamber 2 of the lock casing 1. As illus trated in Fig. 9 it will be noted that the lock block is of greater width than the bolt and is so constructed as to be engaged by the stop block carriage upon its upward movement so that the block will be lifted thereby permitting the shoulders to disengage. The bolt is formed with a finger 36 which extends outwardly from one side thereof and is adapted to engage the walls of the tapered groove formed in the stop block carriage as will be more fully hereinafter described. The opposite side of the bolt is provided with the downwardly extending rack bar 38 provided on its under side with. teeth for engagement with the bolt actuating gear which will be more fully hereinafter described. Y

The stop carrier is designated generally by the numeral 39 and consists of the rear wall 10 provided with a plurality of forwardly extending partition walls 11. This rear wall is formed with a plurality of vertically extending slots 42 formed centrally of the *alls ll and these slots are adapted to receive the blocking arms of the stop blocks which will be more fully hereinafter described. The forward end wall of the stop block carrier 39 is provided with a suitable knob 18 and the whole carrier is made or a size to readily slide through the opening 8 provided in the front wall therefor. 1

The stop blocks used in connection with the device are best illustrated in Fig. 8 and each comprises an oval body 14: provided at its rear face with a groove 15 and centrally with a stem 16 provided at its extreme rear end with the locking arm -17. it is to be understood that this body may be made oval as illustrated in'llig. 8 or may be made circular as illustrated in Fig. 11 without dcparting from the spirit and scope of the invention.

The stop block carriage used in connection with the device is best illustrated in Fig. 10, though in this "form it will be noted that the reinforcing arms are shown but it is to he understood that thesearms may be eliminated at the desire of the user. This stop block carriage comprises a strip oi metal 45% formed with a central slot 19 extending lo-ugitudinally thereof which is provided at its forward end with the oil set portion 50. The rear end of the strip has formed integral therewith the outstanding wall 51 which engages the side walls of the casing 1 and forms a guide for the rear end of the stop block carriage. A longitudinally extending tongue 52 is formed to one side of the slot 19 and is adapted to form a guide to prevent the stop blocks from turning when inserted in place in the carriage. At the forward end of the body 18 is a depending standard 53 provided at its lower end with a pair of vertically extending parallel guides 5a which straddle the wall 17 and form a guide for the lower end of the device. Formed near the lower end of the standard 53 and extending in a direction parallel to the strip 4-8 are the teeth 55 which are adapted to be engaged. by the tooth on the controlling wheel. as will be more fully hereinafter described. In order to hold the two portions of the strip in parallel relation there are provided the connecting member 56 which are provided at spaced intervals and hold the said portions formed by the slots 49 in spaced parallel relation at all times. These connecting members bowed outwardly as illustrated in Fig. 5 so as to avoid interference with the retaining arms 47 of the stop blocks 41 1. A suitable tapered groove 57 is formed at the forwt rt end of the upper arm of the carriage and this groove is adapted to receive the finger 36 of the lock bolt 32 upon rearward more ment, of said lock bolt. The slot 19 is of a width suflicient to receive the stems 46 of the stop blocks 4. 1 so that the blocks may he slid longitudinally of the stop block carriage to aline with the spaces left upon their removal from the carrier 39. H

The adjustability of the stop blocks is effected by the stop block adjuster consisting of a rack bar 58 which is segmental in cross section as illustrated in Fig. 7 and is slidable through a segmental opening 59 formed in the gear wheel 60 which gear wheel meshes with the gear teeth on the rack bar 61 which is slidable transversely through the lock. The outer ends of this rack bar'61 are provided with suitable knobs 62 by which its movement may be controlled. The segmental rack bar 58 is provided intermediate its ends with an upstanding lug 63 provided with oppositely disposed curved faces for engaging the stop blocks so that upon inward or outward movement of the rackbar 58 the stop blocks may be slid longitudinally of the stop block carriage. In order that the lug 63 may pass by one or more ofthe stop blocks without moving the same the rack bar 61 is moved to cause the rack bar 58 to partly rotate so as to swing the lug downwardly into a horizontal position and thus the rack bar 58 and lug 63 will be free to move without disturbing any of the blocks. This wheel 60 is formed with a sleeve 61 which is rotatable in the aperture 20 of the extension 19 of the block 18.

In order to move the rack bar 58 longitudinally there is provided the gear 65 which is secured to the shaft 66 and meshes with the teeth of the rack bar. A suitable pinion 67 is mounted on the shaft 66 and this pinion in turn meshes with the gear wheel 67 on the shaft 68 which gear wheel 67 meshes with the gear wheel 69 which is attached to the shaft 10.- It will thus be seen that upon rotation of either of the knobs 11 the rack bar 58 may be moved longitudinally so as to adjust the stop blocks 44 along the carriage. The shaft 66 is extended beyond the sides of the casing and has mounted thereon the dial wheel 70 provided with a plurality of characters 71 around its periphery which are visible through suitable openings formed in the escutcheon plates, and the edge of this wheel is provided with a plurality of out-- standing teeth or lugs 7 3 which engage the oflset portion 74 of the spring tongue 75 which in turn ismounted on a suitable block 76 secured to one of the walls of the casing. The lugs 73 are positioned in radial alinement with the characters 71 and it will. thus be seen that as the characters appear before the opening in said escutcheon plates, the tongue 75 will ratchet over the lugs and serve to hold the dial wheel against accidental movement.

Keyed to the shaft 10 is a sleeve 77 carrying the arms 78 which engage the springs 79 mounted on the ears 80 of the wheel 81. This wheel 81 is provided with the radial arm 82 carrying a tooth 83 for engaging the teeth 55 of the standard 53. It will thus be seen that upon rotation of the shaft 10 the arms 78 will engage the springs 79 and thus cause the wheel or disk 81 to revolve but it will be apparent that unless the stop block carriage moves upwardly freely the tooth-83 engages the teeth 55 and will stop the rotation of the disk and the springs 79 will give to allow the arms 78 to pass' In this way it will be apparent that unless the proper combination is set up within the lock the same cannot be forced. A similar construction is provided for driving the gear train controlling the rearward movement of the bolt which'train will be described as follows:

Mounted to rotate freely on the shaft 10 is the gear 84 carrying the outstanding ears 85 which in turn support the springs 86. These springs 86 are arranged to be engaged by the arms 87 of the sleeve 88 which is keyed or otherwise secured to the shaft 10 and the gear 84: meshes with a pinion 85 mounted on the stub shaft 86 and this pinion meshesv with the gear 87 mounted on the stub shaft 88 which gear in turn meshes with the rack 38 so as to operate the bolts. It will thus be seen that unless the lock block 35 is raised the bolt cannot be forced backwardly as the spring 86 will give and permit the arms 87 to pass but it will also be noted that the springs will offer sufficient resistance to operate the bolt provided the block 35 is raised. It is to be noted that the lock block is provided with a dovetail groove 89 for the reception of the dove-tail rib 90 formed on one of the side walls of the chamber 2. It will thus be seen that the block will be free to move in a vertical plane but will be held against accidental movement in other directions. Referring to Fig. 11 in which there is illustrated a padlock, it will be seen that the lock casing is designated by the character 91 forming a chamber 92. Formed integrally with the inner face of one of the walls of the casing are the inwardly extending guide tongues 93 which act as guides for the latch, which will be more fully hereinafter described.

The latch above referred to is designated by the numeral 94 and is provided with the beveled end 95 and said latch is adapted to engage the notched end of the shackle 96 which is pivoted as at 97 to the lock. The lower end of the shackle is provided with the curved end 98 which is adapted to engage the bevel face 95 of the latch to force the same backwardly against the compression of the spring 99. Suitable guide walls 100 are formed integrally with the back wall of the casing and serve as guides which cooperate with the tongues 93 and also form stops against which the lugs 101 on the latch abut when said latch is moved forwardly and in engagementwith the shackle. It will thus be seen that the forward movement of the latch is limited so that when the shackle is removed the same cannot move beyond a predetermined distance. Formed integrally with the rear'end of the latch is an extento its open position.

The carriage above referred to is designated generally by the numeral 109 and is constructed. identically with the carriage 18 and is slidable vertically within the lock casing. The stop carrier designated by the numeral 110 is constructed identically with the stop carrier 39 and the stops 111 are constructed and operate the same as do the stops as hereinbefore referred to. The for-- ward end of the lock casing 91 is provided with an opening 112 through which the stop carrier may be withdrawn to vary the combination and. this opening is closed by a suitable plate 113, the upper endof which is formed with the angular extension 11 1 which is engaged by the end of the shackle when the same 'is in locked position. .t will thus be seen that the removal of the plate unless the lock is in open position is prevented.

The stops 111 are adjusted along the carriage 109 by a rack bar 115 which is identical in construction with the rack bar 38and is controlled by the gear 116 which is rotated by the rack bar 117. The rack bar 115 is moved longitudinally by a mechanism which will be more fully hereinafter described.

The mechanism above referred to comprises the disk 118 provided with a plurality of teeth on its periphery which engage the teeth of the rack bar 115 and this disk 118 is provided with the characters 119 which are visible through a suitable opening formed in the casing 91. This disk is secured to the shaft 120 and rotatably mounted on said shaft is the disk 121 carrying the angular extension 122 provided with a tooth 123 for engaging the teeth 12 1 on the standard of the carriage 109. The connection between the disk 118 and the disk 121 is of the same construction as the connection between the disk or wheel 69 and the disk 81. It will thus be seen that any attempt to force the lock will be frustrated.

In the modified form of the stop block carriage illustrated in Fig. 12, it will be noted that the forward end of said carriage is provided with an enlargement 122 provided with an opening 123 and is adapted to be pivoted to the casing. The standard designated by the numeral 124 is curved and provided on its inner face with the teeth 125 for engagement with the tooth on either the extension 82 or 122. In this modified form it will be noted that the carriage instead of moving straight upwardly as in the previous construction will swing on the pi vot which extends through the opening 123 and will engage the various lock releasing means, thus permitting the door or padlock to be opened.

It will be apparent from the foregoing that in use the combination is set by removing the stop carrier 39 and removing certain. of the stop blocks 4:4; and placing the same in the carriage. The carrier is then replaced into the position shown in the drawing and the lock is ready for operation. The user first turns the bar 58 into such a position that the arm 63 at its end extends upwardly to engage the stop blocks 1 1 and upon revolving either of the knobs 11. it will be apparent that the gear train controlling the movement of the bar 58 will move said bar so as to slide the 'iirst of the stop blocks to the proper position. The bar is then turned by the operation of the rod 61 so that the arm or finger 63 turns downwardly and escape beneath the stop blocks and upon turning the same upwardly it will be apparent that the next block may be set to the proper position. This operation is repeated until. the blocks are alined with the openings left for them by their removal from the carrier 89 and the bar 58 is then moved entirely back into the lock whereupon the user upon turning the arm will operate the gear train to swing the extension 82 around so that the tooth 83 engages the teeth 55 of the standard 53.

The engagement of the tooth 83 with the lowermost tooth 55 will move the standard upwardly, thus lifting the carriage until the same engages the under side of the lock block 35 and upon further rotation of the gear train it will be apparent that the bolt actuating gear train will be set in motion to slide the bolt b'ackwardly and out of locking position. The carriage is held against fall ing back to its locked position by the finger 36 which engages the upper inclined wall of the groove 57 and it will be apparent that the farther into the casing the lock bolt is moved the higher the carriage will be raised, thus lifting the lock block clear of the bolt and permitting the same to be entirely withdrawn. from locking position. In this way it will be apparent that the lock may be thrown to open position and may again be lockedby reversing the direction of rotation of the knob to return the parts to their original positions whereupon -the bar 58 is thrown into such a position that the lug 63 extends upwardly and engages the blocks i lof the carriage to assist the same to their original or starting position. Due to the fact that any of the blocks may be removed and placed in the carriage it will be apparent that the combination may be readily riage to aline the same in such a position that they will pass the carrier and means for moving the carriage against the bolt releasing means to release said bolt.
