serial No. 534,701.

In the accompanying drawing, 1 repre-` sents a portion of a safe which is of the usual construction and has within itself no specific reference to the present invention. The safe 1 is provided with the usual door opening, which in this instance is circular and in which opening the door 2 is to be entered and closes the safe in the usual manner. The door 2 is suspended upon a hinged yoke of the usual construction and so connected that the door can be rotated axially. '.lhe yoke is not illustrated as it does not have any specific reference tothe present invention. The periphery of the door is provided with a series of lugs or extended [langes 3 and the periphery of the door opening is also provided with a series of lugs or inward extending flanges, fl,which are so arranged with reference to each other that when the door is closed and rotated the lugs will interlock, thereby, providing means for securely locking the door against outward movement and at the same time necessitating the rotation of the door to bring it in position to be opened. These various lugs or extended flanges upon the door and the door janib are of the usual construction and hence need no detailed description. The door 2 is provided with a chamber, 4, in which chamber the time lock and the bolt releasing mechanism, the springs and the various parts pertaining to the lock mechanism are located. It will be understood that within this chamber 4 is to be located the time locks designed to release the bolts at a predetermined time, which time locks are of the usual construction and form no specific part of the present invention. The lock plate 5 is formed of such a size that the various parts designed to be carried by said lock plate can be properly connected and arranged with reference to each other.

It is well understood that the lock plate 5 should be set in a true vertical position so that the various lock bolts will pass in and out without binding. Difficulty is sometimes experienced in setting` the lock plate, and iii-order to overcome this difficulty provide springs G, the ends ot' which abutV against the liront wall of the chamber fl and the front face of the lock plate 5, which springs are located around the lock plate holding screws 7, which screws are entered in screw threaded apertures S formed in the door 2.

lt will be understood that by providing the springs 6 and locating the springs around the plate holding screws 7, that said springs can be compressed or released by turning the screws 7 in opposite directions, thereby providing means for truing up the lock plate 5. lt is well understood that in the manufacture of safes hard steel or like material is employed and by reason this, much dii'lieulty is experienced if liling must be done in order to true up the lock plate, but by'providing the springs 6 this ditliculty is overcome. It. will be understood that at places where screw threaded apertures are to be formed soft blocks of steel are cast in the door. rllhis art, however, is old, and is well understood by those skilled in the art.

'llo the lock plate 5 is securely attached the spring-case 9 by means of the screws 10. YWithin the spring-case 9 is located the-cross head 11, which cross head is formed of a length to correspond substantially with the spring case 9, but should be so formed that the cross head is free to move up and down for the purpose hereinafter described. Directly below the cross head 11 is located the short bar 12 which is formed integral with cross head 11, which bar is for the purpose of providing means for elevating the cross head through the instrumentality of the setting lever 13, which, lever is located or formed integral with the shaft 14, which shait is properly ournaled in the flange 15 and the lock plate 5. The shaft 1st is provided with the angular extension or shank 16, which angular extension or shank is for the purpose of providing a setting stem, upon which the key 17 is placed when it is desired to compress the springs 18 and 19. The springs 19 move the head 23 upward until it engages the T-head 22 located upon the bar 21. For the purpose of reducing the rictional contact between the end of the bar 12 and the lever 13, said lever is provided with the anti-friction roller 20. F rom the cross head 11 extends the bar 21, which bar is provided with the Ilhead 22, which T,

head is for the purpose hereinafter described.

Upon the bar 21 is mounted the sliding head 23, which sliding head is substantially of the form shown in Fig. 12 and as shown it consists of two parallel blocks held in proper spaced relationship by means of the bridge bar 24.. rllhe sliding head 23 is guided by means of the flanges 25, said flanges being formed integral with the spring case 9. rllhe bar 21 is located between the members of the vhead 23, which members form a guide for the movement of the bar 21.

rlhe tie or bridge bar 2li is provided with the lug or flange 26, to which lug or flange is pivotally attached the link 27', which link is pivotally attached to the disk 23, which disk is mounted upon the stud 29, which stud may be formed integral with the lock plate 5 or it may be made separate and attached in any convenient and well known manner. To the disk 23 is pivotally attached the lock bolt actuating links 30, which links are formed substantially alike and are each connected to the lock bolts 31 and 32, which lock bolts reciprocate for the purpose of locking the door and releasing the door as hereinafter' described. n

lt will be understood that the links 30 and the lock bolts 31 and 32 are to be pivotally connected together by means orp the pins 33, which pins are held in proper position by means or' the integral screw threaded portions 3l, seated in the screw threaded apertures 35, in the lock bolts 31 and 32. For the purpose of allowing reciprocating movement the links 30, and the lock bolts 31 and 32 the lock plate 5 is provided with' the elongated slots 36.

1t will be understood that when the crosshead 11 is moved upward by means of the lever 13 there should bev no upward movement of the head 23, and in order to pr'event this upward movement of the head during the time the springs 13 and 19 are being compressed, the detent or arm 37 is pro vide-d which engages, when in a lowered position, the projection 33 formed upon the lock bolt 32 which prevents an end or outward movement of said lock bolt 32. lt will also be understood that when the lock bolt 32 is held against endwise movement there can be no rotary or oscillating movement of the disk 28 by reason of the links 30 being coupled to said disk and lock bolt 32. By the movement of the lever 13 in a direction to elevate the cross head 11 the springs 18 and 19 are compressed and held in compression by the bell crank or lever 37 and the projection 33 and there can be no action of the springs 19 until released as hereinafter described.

lilith the parts just above described and in the position described the door 2 is in condition to be locked as follows: The door 2 is 3:operly seated in its opening and rotated in the direction of the arrow, shown in Fig. 5 and until the door has assumed the position illustrated in Fig. 6. By this rotary movement ot the door the inclined end of the blade or plate 39 comes in contact with the inner edge 40 of one of the lugs 4, said particular lug being `located in proper relationship with reference to the beveled ended blade or plate 39. By a continuance of the rotation for a limited distance the sliding bolt 41 will be moved inward by means of the flange or blade 39, which inward movement swings or rocks the lever 42, which lever is held in contact with the nut 43, which nut is located upon the bolt 41; as the lever 42 swings inward, the lever 37 is moved upward, thereby bringing said` lever out of engagement with the projection 38, after which the bolts 31 and 32 are moved outward by the action of the springs 19 and their outer ends extended beyond the periphery of the door and into proper sockets or recesses Yformed in the door jamb.

It will be understood that the levers 37 and 42 should be `:formed integral with each other or securely connected together and pivotally mounted upon the screw 43, whichscrew is attached to the lock plate 5. lt will be understood that the blade or plate 39 should be formed integral with the bolt 41 or securely connected thereto, so that the movement of said plate or blade will carry with it the bolt 41. For the purpose of holding the lever 42 in proper contact with the nut 43 or the inner end of the bolt 41, the spring 44 is provided, which spring abuts against the lever 42 and the springcase 9. After the door has been rotated and the lever 37 brought out of engagement with y 30 in an outward direction forcing, with them the lock bolts 31 and 32.

It will be understood that after the bolt 41 has been :forced in and the door locked the door can not be opened until the lock bolts 3l and 32 are brought inward or their outer ends detached vfrom their sockets.

Upon the spring case 9 is mounted the plate 45, upon which plate is pivotally mounted the trip lever 46, which trip-lever is pivotally mounted intermediate its ends. From the trip-lever 46 is extended the trip arm 47, as best illustrated in Fig. 10. When the lever 46 is rocked bymeans of the ordi nary and common time lock lever 48, said lever being pivotally mounted upon the time lock case 49 and when rocked in the direction indicated by the arrow. (see Fig. 1) the arm 47 is moved downward, thereby disengaging said arm from the trip lever 50, thereby freeing said trip-lever 50, at which time said trip lever 50 is free to swing in the direction of the arrow, adjacent said lever, thereby, releasing the catch lever 51 and permitting the upper end of said catch lever to swing in the direction indicated by the arrow. As the, top or upper end of the catch lever 51 swings as above describedits bottom or lower end swings or moves in the opposite direction upon its pivot 51, thereby, releasing the lug 52, which lug is carried by the bar 53, which bar is slidably mounted upon thespring case 9 and is carried by the extension 7 8, which extension is formed integral with the bar 21, but upon the opposite side of the spring housing 9 from which the lug 26 extends from the bridge bar 24. It will be understood that when the lug 52 is brought into an elevated position it will ride upon the inclined edge 55, until it comes opposite the notch 56, at which time the rock bar 57 is elevated, which rock bar on account o1 its rounded corner 58 and rounded corner 59 of the luge 52 has a tendency to swing `the lbar 53 toward the catch bar 51 and engage the notch slot 61 and into the spring aperture or* housing 62. When the lu`g52 is released from the notch 56 the springs 18 will carry the bar 2l downward bymeans of the cross head 11, which movement carries with it the head 23 and rocks the disk 28 by means of the link 27, said rocking movement of the disk causes the locking bolts 31 and 32 to move inward and unlock the door, at which time the door is free to be rotated and swung open.

For the purpose of moving the head 23 downward with the bar 21 whenthe springs 18 are released, the bai-21 is provided with the T-head 22, which Thead carries with it the head 23, thereby causing a rotation of the disk 28 and moving the lock bars inward. F or the purpose of normally holding the arm 47 in an elevated position and in position to engage the trip lever 50 the plunger 63 is provided, which plunger presses against the top or upper end of the lever 4.6, and for the purpose of holding the plunger in such position, the spring 64is provided, which springis located around the plunger 63 `and in the barrel`65, which barrel is secured to the plate 45 by means of the screws 66.

Through the base plate 5 is located the short shaft 67, upon which` shaft is mounted the rock plate 68 which rock plate is provided with the recess 69 and into which recess is seated the bottom or lower end of the lever 46 and when the lever 46 is moved by the time lock lever 48, the rock arm 70 will be moved in the same direction which movement rocks the detent or catch 71 in the position so as to come in contact with the edge of the disk 28 and when the catch 71 is in the position illustrated in Fig. 6 the detent is in position to catch the shoulder 7 2 and prevent any backward movement of the said disk 2S in the event the springs 19 do not perform their function. It will be understood that the rock arm 70 must be seated in the notch a formed in the detent 71, so as to properly actuate said detent. It will be understood that by providing the detent 71 and the shoulder 7 2 there can be no rotation of the disk 28 and hence the lock bolts can not be forced inward and the door opened. It will be understood that the detent 71 never goes into service eXcept when the springs 19 do not perform their function and when they do not throw the links 30 over the center. The principal purpose of locking the disk 28 against rotation is to prevent the lock bolts from being moved so as to disengage them from their sockets in the event the safe proper is injured by explosions or other injury.

It is well understood that experienced burglars will sometimes locate the lock bolts by drilling into the side` of the safe and when they locate themwill move the lock bolts endwise or force the bolts inward, thereby, unlocking the door. pose of over-coming this fault the lock plate 5 is provided with the stop lug 73, which stop lug is so located that one of the links 30 will come in contact with said lug, thereby, preventing the rotation of the disk 28, this feature being best illustrated in Fig. 6. Vhen the link 30 is brought into contact with the stop lug 7 3 the pivotal point of the link is past or above the common center.

For the purpose of preventing the links 30 from displacement from the pin 33 the overlapping straps 74 are provided, which vStraps are connected to the lock plate 5 by means of the screws 7 5 or their equivalents. In some instances burglars attempt to destroy the time locks by a small explosion, thereby permitting the clock or clocks to run down quickly and operate the time lever, thereby releasing the door. In order to prevent the releasing of the lock bolts by reason of a slight explosion the time lock case 49 is set upon a bendable plate or `sheet 7 6 and when pressed in or forced in by the explosion the lug 77, which is formed integral with said plate 76 will come in the path of the pin or lug 78 and prevent any movement of the lock bolts.` The bendable plate or sheet 7 6 is secured to the lock case 49 in any convenient and well known manner and the lock case 49 is carried by the door Q.

For the purpose of preventing the trip lever 50 from ,swinging too far upon its For the purpivotal point when released, the spring case 9 is provided with the stop flange 50a, which is so located that the trip lever 50 will strike said stop flange when the reciprocating bar 53 moves upward. For the purpose of giving a quick movement to the trip lever 50 as the reciprocating bar 53 moves downward said trip lever is provided with the shoulder 51a the movement being imparted to the trip lever by means of the collar or flange 7 8a coming in contact with said shoulder 51a.
