Specification of Letters Patent.

Patented Nov. 24, 1914.

Application filed June 18, 1914. Serial No. 845,795.

To all whom it may concern:

lie it known that \\'e,'Mosns Mosnnn, a citizen of the United States, residing at Cincinnati, Hamilton county, Ohio, and (Ann lhn'rnns, a, citizen of the United States, residing at Hamilton,-Butler-county, Ohio, have invented certain new and useful Improvements in Safe-Doorgof which the following is a specification.

In round door safes one plan of const'ruction is to screw the door into its door-jamb and to prevent unscrewing by suitable loclcing devices. In such type of safe, which we will refer to as the screw door type, the door, in being screwed to the jamb, is given about one revolution and so, also, in being unscrewed from the jainb. In another plan of constructing round door safes, the door is screwed to placebut the screw'is of 1nter rupted character and the helical character of the interrupted thread is so gentle that the screw feature is hardly recognizable. In this second type of safe, which we will refer to as the lug type, the door, in being seated home in the door-jamb, is given but a mere fraction of a turn,-and so, also, in unseating the door.

Our improved door is a compound door in which one component carries the other telescopically, one component being of screw door type and the other cpmponentbeing of lug type, each component having its 1ndividual lock.

Our improved door will be readily under stood from the following description taken in connection with the accompanying drawings in which Figure 1 is a front view of a safe fitted with our improved door, the door being shown in open position: Fig. l a side elevation of the' door with its inner or screw-member protrudod from the front member as when the door is in closed or locked position: Fig. 3 a similar side elevation of the door when the inner-or screw-member is retracted into the front or hig-member of the door: Fig. l a front ele ration of the door: Fig. 5 a rear elevation of tlie doorfFig. (3 a horizontal section of the door with both of its'members seated, and locked into the door-opening of the safe, the section being substantially in the plane of linen ofFigs. 2, 3, 4, 8, 9 and 13: Fig. 7 a similar horlzontal section with the mitew memher of the door retracted into the "lug-member: Fi 8 a front elevation of the door with a portion of the escutcheon plate broken away: Fig. 9 a front elevation of the door with the front plate of thegearcasing removed: Fig. 10 a diametrical section of a portion of the door in the plane of line 0 of Fig. 12: Fig. 11 a diametrical section of a portion of the door in the plane of line b of'l igs. l, 8, 9 and 13: Fig. 12 a plan of the rear portion of the screw-door, a portion of the lug-door appearing in sec tion in the plane of line (i of Figs. 9 and 1,3; and Fig. 13 a vertical section of the lugdoor viewed from the rear in the plane of line 0 of Figs. (3, 7 and 10.

As the door-members are to be considered in various angular positions, such fact should not be lost sight of in consideraing the planes on which diametrical sections a re taken in the various figures of the drawings.

But in our loved construe-hi0 which We will now rihe We employ an inner door and place ie in s renderne loci: on Lhe inner door thu 5 thougl'i of course, a time loci; may ployed upon the outer door also.

Now, understanding thal; the safe has a circular door-opening provided with lugs and adapted to be closed by means of a. lug' 'ed door lumed'a small fraction of u 1 and turned backward, we proceed with the draw ing's.

33, a gear mounted in gear-casing 8 concentric with the axis of the bearings; iii an arm projecting inwardly from this gear and engaging the front end of spindle 30, this gear being journaled within journal 12 of the lug-door so that the gair and arm and spindle may turn independent of the lug-door, the arm being of such width that it may make at least seven-eighths of a turn, relative to the lug-door without being interfered with by the spindle oi the combination lock; 35, a pinion. journaled in the geareasing and engaging gear 33, theillustration showing this pinion as having its axis coincident with that pinion 1l employed in turning the lug-door; ill a noncircular aperture in pinion -35, of the same .l'orm as aperture in pinion l-lso that the same i'ilug-wrein'h may engage and operate the two pinioi'is siinnltaneously; 37. a time lock on the inner portion of the screw-door, the screw-door being illustrated as recessed at its rear to receive a portion of the time lock; 38, an escutcheon plate surrounding the time lock and closing the recess in'the rear of the screw-door; 39, a plate of ma ohineable metal rigidly secured to the rear face ol the lug-door to facilitate the attach ment oi parts it the lug-door he of nonmachineahle metal; 40, (Fig. a, pawl pivoted in the root of the rearmost thread of the screw-door and adapted to he held outwardly by the time lock, and engaging the rear end of the thread of the screw-portion oi the door-jamb as is usual in safes having doors of screw type ;-l-1, a radial pin rigidly held in the recess in the lug-door: and 42. a helically trending notch in cylinder 28 adapted to engage pin 41 when the cylinder 28 inst approaches complete retraction within rlurecess of the lug-door.

Assume the door standing open with the screw door telescoped back within the lugdoor. as indicated in Fig. 3. ll, now. the lllQJlOOI be in such angular position that it may freely enter the door-jamh, the compound door mav he closed and. by applying the plug-wrench in both pinions. the lugdoor may be given the eighth of a turn angeessary to bring about the proper engagement of the lug. and the combination lock may be thrown. Thls securely locks the sate so far as the lug component of the compound door is concerned and this would. he

the pcrforn'iance for ordinary day locking. In this 'i'ier't'ormance the screw door has taken no part for it has simply ridden idly with the lug-door within which it is telescoped. though the eighth turn which has been given to the lug-door has incidentally iii-ea given to the screw-door.

If, now, it be lesired to completely utilize the eompouiul-door the plug-wrench is partially witlulrawn so as to engage only with pinion 35, whereupon the screw-door may be screwed home, the lugaloor being already home, and the time look, at the proper time, may throw its pawl and lock the screw-door.

\Vhen it is time to open the completely locked safe the pluguvrench is applied 10 pinion 35 and, the time lock having gone oil guard, the scrcw door may he witlnlrawn from its seat and telescoped hack into the door lug after which, the lug-door having been unlocked, the plug-wrench may be iii-- serted further so as to engage pinion l-l, whereupon the lug-door may be given iLs eighth turn to release its lugs so that the compound door may be opened',the screwdoor riding idly in the lugdoor. When the compound door is standngopen, or when it is closed, and the screwdoor has not been screwed into its seat, the screw-door is simply idly supported by the lug-door, and in the absence of preventive means, the screwdoor may shift its iosition in the lug-door, or, when the compound door was standing open; the screw-door could he pulled bodily out of the lug-door within which it is telescoped. It is desired that when the com-' pound door is pushed to closed position the angular relationship of the two doors relative to each other and relative to the lugs and threads in the jamb be such that there will be no interlj'erenee of parts when the compound door or either of its components is turned. It is for this purpose that We n'ovide pin ell and slot 42. 156th components olithe door being completely"home, the first action is the unscrewing of the screw-door from its jamh and theitelescoping of that door bacl; into the lug-door. At just about the completion of this unscrewing operation of the screw-door the notch 42 engages pin all, and when the unscrewing and telescoping is completed the scrc\\'-doo1' is held in definite angular relationship to the lug-door and cannot move rearwardly from it except by rotary motion of the screw-door relative to the lug-door. thus preventing a ny shi fting of the screw-door relative to the lug-door in an axial direction as the result of momentum in closing the compound door. lV hen the screw-door is to be put into servicethen the earliest fraction of its rotation relative to the lug-door disengages it from pin 41 leaving the screw-door quite free to slide rearwardly within the lug-door. It will thus be seen that as the screw-door complotes its telescoping into the lug-door it does so by a screw action, the pin and notch representing the two elements of the screw so that this screwing feature becomes effective only at near the con'i 'iletion ol the inward teleswpic action and at the beginning of the outward telescopic action.

in the exemplification herein shown, is a construction in which a complete homing of the compound door is effected by a completerotation, the first eighth turn com pletely homing the lug-door and giving to the screw-door an eighth turn, While seveneighths of a. turn farther given to the screwdoor alone completes its homing. These values will of course be changed if the number of lugs in the circular series be changed or if the pitch of the thread be changed.

In the exemplification herein shown the two pinions are mounted with their axes coincidenhso that a plugwrench may operate upon the outer one alone orupon both simultai'icously. This is desirable but not at all essential, as the pinion for turning one component or" the door may have one position and the pinoin for turning the other component oi the door may have an entirely different position, a condition which would,

of course, require that the'tool employed for turning the pinions should. operate first upon one of them and tlren be shifted to operate upon the other, or else that each pinion be provided with an operating tool.

While, for facility in description, the term Sate has been used, it is to be understood that that term is to include not only such portable structures generally designated as safes but also such larger fixed safe structures as are generally designated as vaults. In vaults the door sometimes closes an opening directly in the front Wall. of the vault, while in. other cases it is employed in closing an opening in the front Wall of a vestibule projecting from the vault. It is to be understood that our invention is to be considered regardless of Whether the safe .bc a small safe-structure, or a large vault-structure, or Whether the door-opening be directly in the front of the structure or ina vestibule added to the general structure.

It is furthermore to be understood that the structure illustrated and described constitutes but a single exempliiication of our invention. We have sought to set forth the principle of our invention and the best mode in which We at present contemplate embodying that principle.
