THEODORE REMLINGER, OF ELIZABETH, NEW JERSEY.

PAIDLOCK.

To all whom it may concern.

Be it known that I, Ti-rnononn REMLINGER, a subject of the Czar of Russia, residing at Elizabeth, in the county of Union and State of New Jersey, have invented. certain Improvements in Padlocks, of which the following is a specification.

The objects of this invention are to provide a padlock which shall be difficult of opening by unauthorized persons; to provide means besides the key means for giving added security; to obtain a novel and improved construction of such a padlock, and to secure other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a view in elevation of my improved padlock from the key side, locked and with the key-hole doors closed; Fig. 2 is an edge view of the same; Fig. 3 is a side view of a portion of the padlock, showing the keyhole doors open; Fig. 4 is a View similar to that shown in Fig. 1, with the front wall of the padlock removed; Fig. 5 is a view similar to that shown in Fig. 4, with a certain slide plate and parts carried thereby removed; Fig. 6 is a section taken on line 66 of Fig. 4, or just above the lock bolt, the keyhole doors being open; Fig. 7 is a section on line 7-7 of Fig. 1; Fig. 8 is a section taken on line 88 of Fig. 4, and Fig. 9 is a detail section on line 9-9, Fig. 5, looking in the direction indicated by the arrow.

In said drawings, 10 indicates the front wall of the padlock, or wall having the keyhole 39, and 11 is the opposite or back wall. 12 indicates the edge wall of the padlock, standing edgewise between said walls 10, 11, and held thereto by stays 13 riveted into all three parts, as shown in Fig. 9.

14 indicates the top wall of the padlock, beneath the shackle 17, and which top wall is shown as a separate piece from the edge wall 12, although it might be integral therewith. This top wall has edge lugs 15 riveted into the side walls 10, 11 of the padlock to hold it in place, and at one end bends downward, as at 16, and is apertured to provide a slideway or bearing for the tongue 20 of the lock bolt 21. The shackle 17 is hinged, as at 18, between the front and back walls 10, 11 of the padlock, and at its other end Specification of Letters Patent.

Serial No. 536,132.

has an apertured extremity 19 to enter the padlock chamber 22 and receive the tongue 20 of the lock bolt. The body 21 of the lock bolt lies flat against the back wall 11 of the padlock and is slotted, as at 23, to slide on a stud 24 fixed on said wall, but the tongue 20 is offset from said body 21 so as to be midway between the front and back walls 10, 11 of the padlock, as clearly seen in Fig. (3. In front of said body 21 of the lock bolt lie four tumblers 25, 26, 27 and 28, their thickness being such that the front face of the front one 28 is flush with the front face of the lock bolt tongue 20. These tumblers are all pivoted on a common pin 29 on the back wall 11, and have individual springs 251, 261, 271 and 281. The tumblers all have vertical slots, as 282, 283 and 284, connected intermediate of their upper and lower ends by slanting slots, as 285 and 286, all said slots adapted to receive a stud 30 on the lock bolt 21. It will be understood that as the lock bolt is slid, the stud 30 passes from the top of one set of vertical slots, as 282, to the next, as 283, and the object of the slanting connecting slot 285 is to insure that the stud 30 cannot go too far, or into the next connecting slot 286, but will hit the side of the vertical slot 283. The key post 31 is on the back wall 11, below the lock bolt and turn blers, and the bit of the key, not shown, is adapted to raise the tumblers and slide the lock bolt, as will be understood. In the drawings, I have shown a construction requiring two complete rotations of the key to slide the lock bolt into fully locked or unlocked position.

Lying flatwise against the front tumbler 28, and serving to hold said tumblers against the lock bolt 21, or in place on their pin 29 and stud 30, is a slide plate 32, parallel to the front and rear walls 10, 11 and intermediate thereof. This slide-plate is mounted upon the front wall, by means of posts 33 having reduced ends 34 riveted into said front wall and opposite reduced ends 35 which enter slots 36 in the slide-plate. The slide-plate is thus adapted to move or reciprocate in the same direction as the lock bolt, and is normally held at the left hand limit of its movement by a spring 37, as shown most clearly in Fig. 4. The said slideplate 32 is apertured, as at 38, to provide ample clearance for the key-post 31 and keyhole 39 in the front plate or'wall, no matter in what position the slide-plate may be. Around the said keyhole 39, at the outer side of the front wall 10 of the lock casing, is a raised frame 40, within which are hinged doors 41 and 42, adapted when closed or folded against the front wall to meet at their edges and cover the keyhole 89, the edge of one door, as 42, having an overlap 43 to cover the joint between the doors. Said door 42 has at its inner side a catch-member 44 which is adapted as the door is closed to project through a slot 45 in the front wall into the interior of the casing. The doors are normally thrown into wide open position by means of leaf springs 411, 421 secured at one end to the inner side of the front wall 10 and projecting through apertures 412, 422 in said front. wall to press at their free ends against the said doors.

The slide-plate 32 has a catch member 46 which is adapted to engage with or release the catch member 44 on the door 42, according to the position into which the slide plate is reciprocated. In normal position of the slide plate the catch members are in engagement, as shown in Fig. 7.

On the outside of the front wall 10 are knobs 47, 48 and 49, 50 arranged in vertical pairs on opposite sides of the door frame 40. Of these knobs one, as 50, has a cylindrical stem 51 extending through a slot 52 in the front wall, and a screw 53 is driven loosely through the slide-plate 82 into said stem 51. By this means the said knob 50 will freely rotate, and yet at the same time can be pushed upon to slide the slide-plate 32 against the power of its spring 37. The other knobs 47, 48 and 49 have stems which are round, as at 471, to turn in the front wall 10, and which beyond said round portions are squared, as at 472, 482, 492, to receive disks 54, 55 and 56, respectively. These disks fill the space between the front wall 10 and slide plate 32, being loose enough to rotate freely. Furthermore, each disk is notched, as at 541, 551, or 561, and adjacent to its periphery are projections 542, 552 or 562, on the slide plate, said projection being adapted to enter said notches, respectively, when the disks are turned into proper position.

In order to enable the knobs 47, 48 and 49 to be set so that their corresponding notched disks will be in alinement with their respective projections, as shown in Fig. 4, so that the slide-plate 32 can be slid by means of the other knob 50 and the doors 41, 42 opened to expose the keyhole, said knobs are provided at their peripheral edges with characters, and other characters are stamped upon the face of the front wall 10, as is common and well known in combination locks.

To further increase the difliculties of an unauthorized person striving to open my improved lock, I have formed the rear of the lock of exactly the same outward construction as the front. To this end the rear wall 11 has a door frame 57 in which are fixed doors, or doors which though perma nently closed present the same appearance as do the front doors 41, 42 when closed. Also knobs 58, 59 and (30, (31 are rotatably mounted upon said rear wall 11, said knobs, however, merely having short round stems riveted loosely into the rear wall, as shown in Fig. 7.

Having thus described the invention, what I claim is:

In a lock, the combination of a casing having a front wall with a keyhole and a hinged outer door adapted to cover said keyhole, a catch member on the inner side of said door adapted to project through said wall, a rear wall of similar outward construction to said front wall with its door permanently closed, a slide plate inside said casing parallel to said walls, means slidably supporting said plate, knobs outside the front and rear walls having stems extending rotatably through said walls, said knobs being similar and similarly disposed, means securing the stem of one of said front knobs to said slide-plate, the front wall being slotted for this stem, notched disks fast on the stems of the other front knobs and lying against said slide-plate, projections on said plate adapted to enter the notches, a catch member on the slide plate adapted to engage the said catch member on the hinged door, and a lock bolt and tumblers between said slide plate and the rear wall.
