O. METZERO'IT LATCH FOR THE DOORS OF-SAFETY DEPOSIT STRUCTURES Filed Jan 10, 1941 /& if
d/z'rezMizervZ2j Patented Oct. 14, 1941 LATCH FOR THE DOORS OF SAFET DEPOSIT STRUCTURES Oliver Metzerott, Hyattsville, Md. Application January 10, 1941, Serial No. 374,011
9 Claims.
The present invention relates to safety deposit box structures.
Safety deposit boxes, such as are designed and used for banking institutions and others providing means for the safe accommodationof-valuables of their customers, usually comprise a series of compartments of varied sizes, each closed by its individual door, and each containing a removable receptacle for the accommodation of valuables. The doors for these compartments usually include duplex locks, one of which is operated by a key retained by the banking institution and the other possessed by the owner of the comp-artment, and the lock bolt can be operated only upon the simultaneous insertion and operation of both keys. .It sometimes occurs that the door of a safety deposit box is closed and locked without the valuables container having been placed within the compartment. This sometimes happens inadvertently, while in some instances it has resulted from trickery on the part of the box renter by purposely withholding the box and later claiming damages for the supposed loss of the box and its contents. It is the primary object of the present inventionto provide means whereby the door cannot be closed unless the receptacle has been properly replaced within the compartment. The appearance of an open door in the series of safety deposit'box compartment is a visual indication that the box has not been replaced.
In carrying out this object, use is made of a latch or bolt movably mounted upon the inner face of the door in such manner that upon opening of the latter the latch will be automatically projected to such position as to engage with the jamb of the door or with a wall of the compartment so as to prevent closing of the door. The latch or bolt is so arranged as to be operated to retracted position when the door is swung to closed position only when the container is properly positioned within the compartment.
The means here proposed for accomplishing this result is of such nature that it may be easily and comparatively inexpensively applied to safety deposit boxes or compartments now in use, and no radical departure from the present construction of such devices is necessary. It will be understood that the mechanism here shown and described is illustrative of a simple form of the invention for accomplishing the desired result, and variations from this construction may be resorted to in adapting the inventionto other or different forms or constructions of safety deposit box' structures.
In the drawing: Figure 1 is a fragmentaryhorizontal sectional view taken through a conventional type of safety deposit box and showing the application of door retarding means'involving my invention,
1 Figure 2 is an elevationof the inner face of the door,
Figure 3 is afragmentary sectional view, on an enlarged scale-through the lower corner of the compartment and door and illustrating the means on the'receptacle for" moving the latch to releasing position,
Figure 4 is a fragmentary sectional View through the-casing and door and showing a mod ified form of the invention,
Figure-5 is'a sectional view taken substantially upon the line 5-5 of Figure 4, and a Figure 6 is a view similar to Figure 4 and show ing a further modification of the invention;-
The safety deposit box structure includes a compartment defined by the side walls l0 and the bottom wall I I; the front end of the compartment being closed by a door I2 hinged at l3. The inher face ofthis door carries a housing M for the lock structure, the details ofwhich are imma-- terial, but which mechanism is controlled by the application of proper keys as will be understood. The receptacle for the accommodation of the valuable's' is' represented at I5, and it will be understood that this receptacle slides freely within the compartment.
The inner face of the door I2 is provided with horizontally aligned spaced keeper or guides [6, within which slides a latch or bolt H. A spring l8 encircles the latch or bolt and'is interposed between one of the keepers l6 and. a collar I9 on the bolt. This spring normally tends to force the latch so that One end thereof projects beyond the lines of the door. The latch, near its projecting end, is equipped with a detent or tooth 20' adapted, when the latch is in projected position, to engage behind an edge of the adjacent keeper so as to lock the said keeper with its end in projected position. The keeper for this end of the latch will be so constructed as to permit of lateral play of the latch within the keeper, and a flat spring 21 may be employed, if desired, to yieldably hold the latch in such position thatthe toothlll is engaged behind the keeper. When thus locked in this projected position, any attempt to close the door will be resisted by the latch, as the latter will engage the jamb of the door or the inner face of the compartmentwall and thus maintain the door in the partly opened position as shown by dotted lines in Figure 1.
The door may not then be entirely closed and locked until the latch has been raised to move the tooth 20 from looking engagement with its keeper I6.
The valuables receptacle I is provided in its forward end with a forwardly projecting arm 22, so positioned as to underlie the forward end of the latch I! as the door moves to closed position. The forward end of this arm is provided with a cam or inclined face 23, upon which the latch end rides in an upward direction as the door is swung to closed position. It will be understood that the arm 22 will be accurately positioned upon the box or receptacle l5 so that when the latter is correctly inserted within the compartment, the operative or inclined face 23 of the arm end will be disposed in the direct path of the latch as the door is moving to closed position. As the latch rides upwardly upon the face 23, the tooth clears the lower edge of the keeper l6, and continued closing movement of the door will cause the latch or bolt IT to be retracted against the-tension of spring 18. By this arrangement it is obvious that the absence of the receptacle with a properly positioned operating arm 22 within the compartment will prevent closing of the door.
In Figure 4 of the drawing the door 12 is shown as provided with a slide bolt or latch 24 disposed laterally of the door and slidably upon pins 25 projecting from a base plate 26 properly affixed to the interior face of the door. The latch 24 is provided with slots 21 for the reception of these pins. A trigger 28 is pivotally mounted as at 29 intermediate its ends upon the plates 26. end of this trigger rides in a recess 30 in the latch 24, and a spring 3| normally forces the trigger to such position as to project the latch 24 below the edge of the door l2. The trigger projects inwardly of the compartment in such manner as to engage the inclined face of an arm 32 projecting from the forward end of the receptacle l5.
In this form of the invention, upon opening of the door the spring 3| immediately causes the latch 24 to be moved to projected position with the inner end of the trigger elevated. Should an attempt be made to close the door in the absence of the box l5 within the compartment, such movement will be resisted by engagement of the lower end of the latch 24 with the outer face of the compartment. Upon insertion of the boxwith its properly positioned arm 32 within the compartment, closing movement of the door.
One
causes the trigger to ride upon theinclined face a of the .arm 32, to rock upon its pivot 29 and to retract the latch member as shown in full lines in the drawin The modification shown in Figure 6 is a slight variation of the structure of Figure 5. form there is no projecting arm upon receptacle l5. The latch 24 is operated by the trigger 28 as shown, and this trigger has a toe 33 at its inner end to engage directly with the forward face of the receptacle l5 when the latter is properly potails may be resorted to without departing from In this 1 the spirit of the invention as defined by the claims.
Having thus described my invention, what I claim as new and useful is:
