Patented July 3, 191'?.

.Application `filed December 31, 1914. Serial No. 879,964.

T0 au a0/1,0m it may concern.'

Be it known that I, HARRY citizen of the United States, Alliance` J. Hron, a Y residing at i in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Locks, of which the following is a specification.

The invention relates to locks for fire proof cases or cabinets vhaving all the locking parts placed within the case to protect the same from fire or other elements, and being arranged for locking without the use of a key while requiring a key to unlock them. Such a lock is set forth in my former application, filed June 8, 1914, Serial No. 843,603.

The object of the present improvement is to construct and arrange the parts so that the locking elements located on the separable parts of the case or cabinet can be engaged for locking by a preliminary operation of the lock, while the cabinet parts are adjacent to but not in Contact with each other; and so that by a further and final 0peration of the lock, the separable rims of the case or cabinet can be drawn, clamped and positively held in sealing Contact with each other.

The general object of the invention, and other attendant advantages, are attained by journaling or swiveling the locking plate on the periphery of a disk eccentrically secured crosswise on the inner end of the operating stem, by mounting` the latch upon the eccentric disk and providing a keeper notch and stops for the latch upon the periphery of the locking plate, and by providing stopping means for limiting the rotation of the locking plate in opposite directions.

The objects of the invention, thus briey set forth, are attained by the preferred embodiment thereof illustrated in the accompanying drawings, forming part hereof, in which- Figure 1 is an inner side elevation of the lock showing fragmentary parts of the case or cabinet clamped together and the locking elements in locked position;

Fig. 2, a section of the same on line 2 2, Fig. 1;

Fig. 3, an elevation similar to Fig. 1, but showing the position of the locking elements at the end of the preliminary locking operatien;

Fg- 4, a Similar elevation showing the parts throughout the drawings.

The operating elements of the lock may,

include the stem 1, the handles 2, the key cylinder 3, the key 4, the eccentric disk 5; and the locking elements may include the locking plate 6, the latch 7, and the locking post `8.

The stem 1 of the lock is provided with the journal 9 on its inner end extending into l and through the corresponding` bearing 10, provided in the wall 11 of the case or cabinet; and when this wall is made of spaced surface plates 12, with intervening` heat resisting material 13, as shown, the journal bearing 10 is preferably made in the bushing 14 secured between face plates 12 of the wall, which face plates are provided with apertures corresponding to the journal bearing in the bushing.

The annular shoulder 15 is preferably provided on the stem of the lock in abutment with the outer face ofthe wall, and on the head 16 of the stem are secured the diametrical opposite radial handles 2 which can be conveniently grasped by the hand of the operator for manipulating the lock and opening and closing the case.

The stem 1 is also provided with the axial bore 17, which extends from the inner end of the stem outward to a point within the outer end thereof, thus leaving a solid front face 18 for the outer end or head of the stem; excepting that the slot 19 is provided therein for the entrance of the wings 2O of the key 4, which slot is preferably provided with a central enlargement 21 for the shank 22y of the key.

The key cylinder 3 is fitted neatly in the bore of the stein, and is provided in its outer end with the diainetric slot 23 having the central enlargement 24 for receiving the Wings 20 and the shank 22 of the key; and on its inner end with the diametric tongue 25 protruding inward beyond the inner end of the stem.

The operating disk 5 is eccentrically secured on the inner end of the operating stein as by means oi' the screw threaded shank 26 on the inner end or' the stem entered in the 'corresponding aperture 27 in the disk and .held thereon by the nut 26 screwed upon the shank; the shank and the aperture being iiattened on one side to stop a rotation of the disk with reference to the stein.

The peripheral flange 28 extends outward from one side oit the periphery of the disk, in which flange is provided the diametrically opposite guide-Ways 29 which receive and guide the latch 7 in its endivise movements, which latch is diametrically located on the inner side of the eccentric disk.

The latch 7 is slidably retained by the cap screw 30, having its shank extended through the longitudinal slot 3l ifoiined in the latch, and screwed into the body of the disk. The latch ispalso provided with the cam orifice 32 which receives the diametric tongue 25 on theV inner end ot the key cylinder; the edges ot which tongue operate against the squared end 34 ot the orifice 'for moving the latch in one direction, as shown in Fig. 4, and the ilat sides of the tongue may abut the saine end ot the oriiice and may stop its movement in the opposite direction as shown in Figs. l and 2. The spring 35 is also provided iii bearing engageinent with the latch and the disk so as to move the same in the opposite direction from its operation by the cylinder tongue, for the locking operation of the latch.

The locking `plate 6 is rotatably mounted or journaled on the eccentric disk so that it fits neatly around the entire periphery and has a portion 36 oi' its periphery circulaily formed concentric with the center of the disk, over which peripheral portion of the locking plate vthe lateral tongue 37 on one `end of the latch extends when the same is in its unlocked position as shown in Figs. 3, 4 and 5; and While in this position the spring 35 acts to draw the tongue inward until it is stopped by a sliding engagement with the periphery of the locking plate Whenever the key cylinder is turned to bring the tongue 25 on its inner end transverse the latch, jas shown in Figs. 3 and 5, which is lthe position vto, which the cylinder must be turned to Withdraw lthe key from the stein o the lock.

The stop 38 is provided at one end of the stop slide portion 36 of the locking plate, for 'stopping the 'relative rotary movement of the latch and the operating disk with reference to the locking plate in one direction; and the keeper notch 39 is provided in the periphery or' the locking plate at the other ,end of the stop slide portion 36 thereof,

into which notch the tongue of the latch is adapted to enter and be held 'for holding vkand securing the operating and locking elements in locked position, as shown in Fig. 2; the entrance oi the tongue into the notch being eliected by the' action of the locking spring 35, Whenever the tongue of the latch is rotated to register with the notch.

To prevent a binding of the latch tongue against the- sides 40 and 40a of the keeper notch, the stop pin 41 is preferably provided on the side of the locking plate in the path of the lug 42 on the periphery of the eccentric disk; which lug is adapted to impinge and be stopped by the pin after the latch tongue clears the one -side 40 oit the keeper notch and before it impinges the other side 40"L thereof, as shown in Fig. l. It will be understood, however', that the use ot theseparate stop pin 41 is not essential7 for in lieu thereof, the side 40 of the keeper notch may be extended, as shown, and Will serve as a stop for the latch tongue, to pre vent its moving beyond the keeper notch.

The stop post 43 is provided on the inner side of the Wall l11 oi' lthe case or cabinet, for limiting the rotation of the locking plate in opposite directions. This post preferably protrudes into the slotted aperture 44 provided in the locking plate, one end 46 ot which 'slot forms an abutment for liin iting the rotation of the locking plate in one direction in' its normal unlocked position, as shown in Fig. 4; and the other end 4Gn forms an abutment for stopping the r0- tation of the locking plate in the opposite direction in an abnormal unlocked position, as shown in Fig. 5.

And finally, the hook 47 is provided on the extended end 4S of the locking preferably diametrically opposite from the keeper notch 89 in the periphery thereof, which hook is adapted to engage and cooperate ivith the locking post 8 secured on theinner side of 'the Wall 11a, to the rim of Which Wall the rim Aof the wall 11 is designed to be clamped and locked.

The locked relation of the parts is shown in Figs. 1 and 2, with the lateral tongue 37 of the latch engaged in the keeper notch 39 iii the periphery of vthe locking plate. In' this relation of the parts, it is evident that by inserting the Wings of the key through the slot 18 in the stem into the slot 23 in the key cylinder, the cylinder can be rotated by the key so that the tongue 25 on its inner end Will move the latch longitudinally, against the action of the lock plate, 1

in the periphery of the locking plate. After the latch tongue is thus disengaged, the ecw centric disk may be rotated by the stem and the handles, and the tongue of the latch will pass over and along' the stop slide portion 36 of the locking plate, as shown in Fig. 4.

The hook 47 being' engaged with the locking post S, the first portion of this rotation swings the upper end of the locking plate to the right, as the lock is illustrated, by the rotation of the eccentric disk in the locking plate; and the turning of the eccentric disk in the locking plate carries the lateral tongue of the latch from above the keeper notch, over and along the stop slide por tion 36 of the locking plate, and also moves the locking plate downward until the end of the hook 47 is disengaged from the locking post, as shown, approximately, in Fig. 3.

If the key is permitted to remain in the lock with the tongue 25 on the key cylinder holding the latch tongue free of the stop slide, during the further rotation of the eccentric disk, and after the hook 47 is disengaged from the locking post, the locking plate may hang without rotation on the eccentric disk, until the latch tongue strikes the stop 38 on the locking plate, as shown, approximately, in Fig. 3; after which this plate is rotated with the eccentric disk to carry the hook 47 clear beyond the side of the locking post 8, and the turning may continue until further rotation is stopped by contact of the end 46 of the aperture 44 with the stop post 43 on the wall of the case, as shown in Fig. 4.

When, however, the key is turned for removing from the stem, which turning rotates the cylinder tongue crosswise and permits the latch tongue to press against the stop slide by action of the locking spring; or when the swivel bearing of the locking plate upon the eccentric disk is fitted closely enough to irictionally engage these parts; the locking plate may begin to rotate with the eccentric disk, just as soon as the hook thereon is disengaged from the locking post, and may continue rotating until the plate is stopped by the post 43; after which the latch tongue will slide upon the stop slide and the eccentric disk will slide within the swivel bearing of the locking plate, until the latch tongue impinges the stop 33 onv the locking plate, as shown in Fig. 4, which prevents turther movement of the locking elements. In this relation of the parts, which is ret'erred to herein as the normal unlocked position of the lock, the handles of the stem are preferably located in horizontal position so that they can be readily grasped for raising and lowering the upper portion of the case or cabinet on which they are mounted.

For rengaging the hook of the locking plate with the locking post, and drawing.l clamping and locking the separable parts ott the case or cabinet together; the stem otl the lock is first rotated by its handles in the reverse direction, until the shank 49 ot the hook impinges the side of the locking post S, with the hook immediately below the post, as shown in Fig. 3; and as shown, this operation may be made when the rims oi2 the case or cabinet parts are spaced apart at a substantial interval from each other.

In event the key has been rotated to rc move it from the stem, so that the cylinder tongue has been turned crosswise and the latch tongue is drawn against the stop slide by action of the locking spring, as shown in Fig. 3; it is evident that the locking plate will be rotated more or less positively into this position by the turning of the eccentric disk, and the rictional engagement ot the latch tongue with the stop slide; and even though the key is not turned for removal :from the stem, and the latch tongue is held free from the stop slide as shown in Fig. 4, the irictional engagement in the swivel bearing on the latch plate on the eccentric disk, or the mere weight of the hooked end of the locking plate, serves to carry the hook laterally from the position shown in Fig. 4 to the position shown in Fig. 3, when the eccentric disk and latch are rotated to the position shown in the latter gure.

lVhen the parts of the lock are in this position, it is vident that a further rotation ot the eccentric disk in the same direction will cause the latch tongue to slide upon or move freely along the stop slide 36, depending upon the position oi" the key cylinder; and the turning of the eccentric disk in the swivel bearing of the locking plate, carries the same upward so that its hook will first engage and then draw the locking post to clamp the rims of the separable parts of the case or cabinet together. The parts are so arranged that when this is accomplished, the tongue of the latch will have moved directly above the keeper notch, into which the tongue is drawn by action of the locking spring, as shown in Fig. 2; the stop pin 4l on the locking plate and the stop shoulder 42 on the eccentric disk being arranged to stop the parts in proper position so that the latch tongue will freely enter the keeper notch without rubbing against either side thereof.

To prevent such a turning of the partel iu the reverse direction as will permit a locking oi the latch tongue in the keeper notch, when the hook is disengaged 'from the locking post. when the case or cabinet is opened as shown in Fig. the contact ot the end 46 of the slot 45 against the pin 43 servos to stop the rotation ot the eccentric disk and the locking plate in the reverse direction,

before the latch. tongue is rotated iar enough to enter the keeper notch; the stopping of the disk and latch being accomplished by the relative positions of the center of the eccentric disk and swivel bearing with reference to the center oiA the locking stem, which prevents a further turning of the disk in its sivivel bearing after the locking plate is stopped to prevent a i'urther downward and lateral movement of the center ot the eccentric disk toward the stop pin A3.
