for burglar proof chests adapted to hold the" collections made at the individual stores, the-' aters and stations,,which chests or safes, as

they areirequired in large numbers by thevarious individual organizations, must to meet this demand, be manufactured andsold at a relatively small cost, and they further must for this trade be so constructed as to enable the proprietors to obtain insurance at preferential rates. The chestsprovided at present for this puropse are not satisfactory in that when constructed to meet the requirements they are-too expensive. I The doors and the labor required to fit and mount the same, and particularly thehinges, are a considerable itemof expense.

The present invention relates to a chest and to a door structure and details for mounting and securingthesame whereby: the use of hinges is avoided andthe maximum of security and convenience is obtained-at the minimum of expense, the structure being one which can be produced: in large quantities much more cheaply than any chest prevlously offered which is adapted to the same general purposes, -The invention further provides for the normal retention of thedoor in mounted position without danger of accidental release and forthe convenient removal of the doorwhen open and it may providedouble custody where it is found desirable, there be v ing for this purpose an mner compartment so arranged that while it ispartially accessible to the employees of the lndiv dual stores or I stations who are acquainted with the combination in order that they may depositthe money as collected, which is usually made into packages and introduced through a slot organization who carries thekey for this s purpose;

Instead of a; single inner compartment guarded byan inner door, the inner door may be so arranged as to provide beyond the chest the top of the safe flIlCluEL with" the door removed.

Referring to the drawings by numerals, each of which is used to indicate the same or similar parts in the different figures, the construction shown comprises a chest body 1, which may be of any preferred or convenient shape and provided with ears 2, by which it may be anchored in a suitable concrete structure or secured within a safe or similar enclosure in accordance with the prevailing practice. In order to obtain the benefits of the preferential insurance rates, the walls of the chest body should be made at least an inch thickof any suitable steel or steel alloy used for this purpose. The chest as shown is provided with a chest door opening 3, near the front end and spaced inwardly therefrom as shown, the opening 3 being shown as substantially semi-circular and slightly less than half the area of the chest door 4 and the door jamb opening to be hereinafter described. As shown, opening 3 occupies the upper half of the cross section of the chest being spaced slightly above the centerwith its straight side at the bottom of the opening. The chest door or main door 4 is of circular outline'and preferably of one and one half inches or more in thickness throughout its area to comply with the requirements for the above mentioned preferentialinsurance rates. This main or chest door 4 is without hinges or similar supportin means, being mounted to rotate in a circu or door jamb or seat 5 of corresponding size located outside the door opening 3 and within the end or end edge of the chest body 1.

The door may be rotatively secured in any suitable manner preferably the door jamb or seat 5 is formed with. an" annular inwardly disposed roove 7, the outer wall of which consists o a likewise inwardly disposed annular rib 8 and the door is formed as to its outer edge with a peripheral groove 9, which receives the rib 8, and the door is likewise provided with a peripheral outwardly projecting; rib 10, forming the inner wall of groove 9-which rib engages and follows the groove 7 in the jamb or seat. The door 4 is supported and guided-mainly in and by circular-or short cylindrical seating surface 61 forming the outer portion of amb 5. This surface is closely engaged by a correspond- 'ing cylindrical surface 62 on thedoor which guides and supports the door, said surfaces being finished concentrically. The ribs 8 and ferred to as the inter-engaging members or ribs, are each. of them interrupted or discontinued at intervals, so that the door being in closed position in which it may be locked, it may, having been duly unlocked,'be rotated to full open position and the stop to be described being released, be then further rotated in the same direction to a position in which the arcuate portions of the rib 10 to be further described, overlie the spaces between the portions of the rib 8,permitting the door to be removed and replaced.

To provide for opening the door, the door or door member 4 is formed with an aperture 12 which is preferably. semi-circular in outline as shown and adapted. to register with door opening 3, being similarly shaped and located relatively to the center of seat 5 about which the door 4 rotates when mounted in the chest. The aperture 12 is shown as of a size somewhat less than half the area of the door 4 so that its arcuate edge 13 is conveniently spaced inwardly from the edge of the door providing a suitable marginal portion 14 to support the ribv 10 or the arcuate sections thereof to be described. The flat side 15 or other portion of the aperture 12 in the door .I

4 which is nearest t-hecenter is also preferably, spaced outwardly from the center of the jamb 5 and of the door. This opening 12 is thus practically of the same size as the door opening 3 and to, open the door mounted as described it is rotated to bring the opening 12 in the door into registration with the door opening 3, see Figure 12. To close the door it is rotated 180 degrees from this position or through any suitablearc depending on the 1 already described, the door jambseat 61 conifi tains a. stop groove 16or the equivalent to be engaged by a stop pinl'T to limit the normal rotation of the door from open to closed position and vice versa, the object of the stop mechanism being to prevent the door from,

becoming disengaged, otherwise than with the intent of the operator. Vhen, however,

' as already pointed out, it is desired to remove the dooror insert it, the stop pin 17 is withdrawn.

To provide for its normal engagement andv eral edge 18 of the door in a hole or guide 19 Which extends throughthe peripheral face of the door, is urged outwardly into engagement with groove 16 by a coil spring 20 in thehole behind thesliding pin or stop bolt 17 and the sliding pin or stop bolt '17 is provided with a laterally projecting lug or handle 21 which slides in a bayonet slot 22 formed in the back of the door and extending into the hole or guide 19so that it is out of reach except when the chest door is Open; Thislug or handle 21 can be engaged by the operator in snobvious manner when the door is open, the operator reaching inside for this purpose and being thus engaged, the stop in l7'c'an be withdrawn and locked in withc rawn position by rotatingthe pin or bolt 17 until the lug'or handle 21 moves into the -base24 of the bayonet or L shaped slot 22. When the stop pin or bolt 17 is thus withdrawn, the door being opened and therefore essentially unlocked,

it can be rotated oppositely to the direction of closing beyond open position to a position in which it is released and may be removed,

As already suggested, the" interlocking ribs 10 on the door and 8 on the door jambare discontinued or interrupted at intervals forming rib sections which interlock and hold the door in its seat in all positions to which it can be rotated when the stop pin or bolt 'l7'is advanced engaging the groove 16. The

exact length spacing. and arrangement of the sections and the form of the interlocking means is capable of widevariations, apreferred, arrangementbeing illustrated in Figure 4, showing the door, and Figure 7 showing the door opening in the chest, the door being removed, and Figures Sand 15,'show-' ing the door in position in the chest.

In accordance with the illustration, Figure 4, the riblOon the door consists of spaced arcuate outwardly projecting sections. At the top in the closed position of the dooris the section 26 which is, relatively long, comprising an arc of about 90 degrees, and proceeding around the door in' right handed ro tation as seen from the rear in Figure 4,.next

to the r1b28 is a space 27 which is about the ribs and Spaces Onfthe door and door j same length as rib 26,.and next beyond this spaceis a short rib 28.- Next is a space 29 a little shorter than this rib, and beyond the space 29 is a rib 30 shown asa little shorter than the rib; 28, next is a space 31 longer than rib 30. Following this is a rib'32 about the length or" thespace 31 and beyond this is a space 33 of a little less,thanthe length of' rib 26. While the spacingin the formpof the invention shown has been described, the exact spacingof the ribs and 'their length is immaterial'otherwise than as it contributes to the resultand object which is to hold the ,f

door and permit it to be rotated from open to closed position and vice versa, and to permit projecting rib 8 on the door jamb comprises in the preferred formof the invention as shown the following arcuate sections suitably spaced, i. e.,,at the top is a long section 35 of the rib 8 comprising an arc-of a length a little less than the length of the space 27 on the door, and proceedingin right handed rotation as the chest is seen in Figure 8, this is followed by a space 36 a little longer than the rib 26 on the door, following which space is a rib 37 a'little shorter than the space 33 on:

the door; Beyond this rib 37 is 'a space 38a little. widerthan the rib 32 on the door and next beyond this space 38 is a short rib 39a little shorter than'space 31 on the door. Beyond the rib 39 is a'space 40 a little longer pass the rib 28 on the door. As pointed out regarding the sections of the rib 10 on the door, the spacing of the sections of the rib 8 on the doorjamb maybe widely varied, and

is only material to the result that the door be held against removal in closed position and in normal openiposition and throughout the path of rotation from one positionto the other. Inthe form shown the rotation-ofthe door is normally limited to this path or a slightly longer one by means of the removable;

than rib 30 on the door. Beyond this space 10 is a rib 11 a little shorter than space 29 on. the door and between the rib 4:1 and the top rib 35is a space l2 which, is long enough to stop latch 17, but this may be omittedorthe result otherwise accomplished within the scope of the invention, the door being preferably capableof rotation when the stop latch is released, to. a position in which the sections of the rib 10 on'the door are thrown'out, of

contact with the sections of. the rib Son the" 'jamb and into registration with the spaces between said ribbed sections whereby the door may be removed, or when. presented in the same angularposition may be inserted. In the construction shown the position of registrationis indicated by the comparison of the contained in the description of the door j amb Y To reach position? clockwise from the closed position, Figure 8, a

to full open position and the stop 17 having been withdrawn, the door is further rotated in the same direction until space 27 on the door registers with rib section 35 at the top of the door j amb, see Figure 15. In this position the rib sections on each-member register with the-spaces onthe other, permitting the" removal and replacement of the dooras aforesaid.

In addition-to the stop pin 17, the door is provided with a bolt which slides outwardly beyond the periphery of the door and is controlled'by any suitable lock 46 shown as ofthe combinationtype. The outer end of the-bolt 4-5 in locked position occupies a keeper slot 47 in the door jamb. There .is also a second slot 49 to be engaged by the Jolt in the partly open position, Figure 10, in which position the combination of the lock canbe changed by means of a pin placed in slot ll), Hole 49 is also utilized in this connecton. In this position of the door the stop 17 can conveniently be reached and withdrawn. The door is also shown as provided with handles or hand grips 4-8.

. The locking bolt 45, the lock 46 and the stop 17 are in the preferred form of the invention shown located in the semicircular half of the door which is at the top in the closed position of Figure 1. This portion of the door overlies a semicircular depression 65 in the rear face of the door and forms the outerwall or base of the same, the exact shape of the depression not being of great importance. By means of th s depression the stop member 17 is made easily accessible from the rear while the slot 16 which it engages is near the front. The depression also provides room for the lock 46 without reducing the capacity of the chest and keeps the entire area of the door of the desired normal thickness, avoiding unoue weight and expenditure of material, and allows ample thickness at the edges to accommodate the rib 10, the groove Eland the. cylindrical seating surface 62 at the front.

The dcprcssiou65 is closed at the side which is at the bottom in the position stated by the d ametrical wall or thickened portion 64-, which has its rear surface in the rear radial plane or finished rear surface 80 ofthe door Which contacts the forwardly disposed rearmost surface 81 of the jamb, sealing the periphery of the opening 3 at all points in gas the closed positon, Figure 1.

In the conduct of chain stores and oil stations. it is desirableto have the chestor safe so arranged that the collections may be deposited. in each individual safe by the employees of the store in which it is located, the employees being. however, harredfroin access tothe safe in a manner which would enable them to remove the contents. the money being subsequently removed by an employee who acts as collector for the organization and has sole access to the contents of the safes of the entire cha n or a considerable portion of it for this purpose. To this end, the present structure be provi with a second or inner door 50 which clo s one door opening 3 inside the main or chest door. the inner door 50 being held in closed position by a su table typeof key lock 51 to which the collector referred to will carry the key and by suitable tenons 59 fitting in slots 60. This door in the form of the invention shown is semi-circular, fitting the door opening 3 which is finished with a peripheral seat 52 to receive the door, the seat being slotted at the bottom to admit any suitable tongues or projections or edge portions 53 at the bottom of the door, the door being then swung into position and secured by means of the lock 51. This lock is shown as having a bolt 54 which enters a keeper 55'formed in or secured to the body of the chest wall. To provide for the deposit inthe safeof the money as collected, the inner door 50 is slotted at 56 or the safe may be provided with achute 57 for the admission to the inner compartment 58 of envelopes or packages of money or other valuables. This latter is in accordance with the practice in moving picture houses in which the safe is placed below the ticket window so that the money can be packaged and dropped into the safe as and when a sufficient quantity is collected.

In Figures 13 and 14 I have shown a slightly modified construction providing for double custody, the inner door 66 in this instance be ng arranged horizontally and opposite or slightly below the bottom of the chest door opening 3, the inner door 66 with its frame 67 and the supporting lip therefor 68, which is formed on the inside of the chest body 1, for this purpose, comprising a horizontal partition which divides the inside of the chest into an upper chamber 69, which is immediately accessible through the door opening 3 and a lower chamber 7 O, which is accessible only from the upper chamber 69 by way of the inner door 66, or, more properly, the inner door opening 71, which is closed thereby. The inner door 66 is shown as provided with a slot 7 2 for the admission of envelopes, and similar packages of money and the like and is secured in an suitable manner as by means of a lock73 w ich'is preferably of the key type, having a bolt 7 4, which enters a suitable keeper slot 75 at one side of the door jamb or groove 76 in the frame 67 in which the door rests, the door having at the other side a suitable tongue or tenon 7 7 which enters a corresponding slot 78 in. the door frame.

-The manner of using and operating the chest and particularly the chest door has been quite fully explained in connection with the. descriptionof the structure. Assuming that the chest door4 has been removed and is to be placed in position, it is engaged by the handles 48 and inserted in the jamb 5, being rotated to the position in which the sections of'the rib 10 on the door register with the ,spaeesbetween the sections-of the rib 8 on the jamb asindicated in Figure 15. In this position the stop 17 i and the bolt 45 being withdrawmthe stop pin 17 being held in withdrawn positionby inserting the lug 21 thereon pass thesections of the rib 8 in the j amb and enter the groove 7 in the jamb when the door can best be rotated to the position shown in Figure'lO, .in which position the stop or stop pin lTmay be released and allowed to enter the-stop groove 16 Thebolt 45 may be caused to enter the slot 49 as a'c0nvenient means for locating the doorin' this position. \Vhen the stop 1'? has been released and allowed to move by expansion of the spring 20, to operative position, the bolt 45 being withdrawn, the door maybe rotated to closed or to full openposition to suit the I convenience of the operator, being'locked in closed position by the-entrance of the bolt 45 into the keeper slot47', the door opening I '3 bei'ngpreferably eccentric as to the jamb and door and the aperture 12 in the door being likewise preferably eccentric as shown. The openingB is uncovered and the chest is opened by rotating the door toa position in which the opening 3 and aperture 12 are in registration and the chest door is closed by rotating to place the aperture 12 completely out of registration and out of alignment at all points with the opening 3. To give the desired protection for the contents of the safe and to avoid cracks and openings between the door and the door jamb, which would be a source of weakness in case of an attempt-to crackthe safe, the surfaces of the grooves and ribs 7, 8, 9 and 110 are preferably finished and suitably fitted likewise the cylindrical outer surfaces 61-62 of the jamb and door, the rear surface of the door and the forwardly disposed rear surface 81 of the door ja'mb providing a close fit as to the meeting surfaces 'which contributes to the closing and guardingof the door opening 3 in the closed-positionof the safe. The use of the inner door 50, Figure 1, permitting the insertion of envelopes or similar packages of moneyor the like through the slot 56 to be retained in. the safe, said packagesbeing only accessible to, the'person, presumably the authorized agent of the owner, having possession of the key, the lock 51 being shown as a key lock, though any suitable lock may be used within the scope of theinven- 'tion, has been fully explained. The door is shown asanchored to prevent removal from thesafe by means of a chain 83.

The use of the construction, Figures 13 and 14,'is similar except that the contents of the upper chamber ,69 is accessibleto all those having access to the safe for any purpose while the lower compartment into which packages and envelopes may be introducedby wayof aslot 72 is closed by a separate lock, usually a key lock, so that the contents from reaching may be handled by a collector-or other per- 7 son duly authorized I have thus described specifically and, in

v 1. In a chest having a circular seat, adoor opening which is eccentrically located within the seat, and a compartment of a cross sec-.

tional area substantially larger than the door opening and substantially coaxial with said seat, door having a rotary engagement with the seat and having an aperture whlch 15 also eccentric and adapted to bemoved into and out of alignment with said-opening thereby openinggand closing the same by rotation of.

the door, and means for locking the door against rotation.

2. In a chest chest body having a circular seat and a door openin which is eccentrically' located as to the seat, a door having a rotary engagement with the seat and having an apers ture which is also eccentric and adapted to be moved into and out of alignment with said opening, opening and closing the same by rotation of'the door, means for locklng the door against rotation, a removable stop limiting. the rotation of the door but permitting it to be moved from open to closed position and" vice versa, interengagingmeans on the door and safe body guiding and holding the door in operative relation to. the seat and provid mg for such rotation, the same having a polnt of disengagement reached when the door is rotated to 'a predetermined point beyond the arc of rotation permitted by the stop when in engagement.
