sum 2 ur 5 IDEVIClE FOR DEPOSITING MONEY AND VALUABLE OBJEC'IS The invention relates to a device for depositing money or valuable objects and the like into a space, such as a safe, wherein money or other valuable objects can be stored by anybody at any time, so as to safeguard these objects against undesirable use. These safes frequently occur in the form of so-called night safes. In these known, frequently used safes the inserted object is directly dropped into the safe. lf for a criminal or wanton reason a liquid or a burning object would be inserted, there is a possibility that the contents of the safe will be destroyed.

The structure according to the invention is such that the entrance to the device compries means to ensure that only the desired objects can reach this space in the desired state and that inserted objects that may lead to damage cannot penetrate into the space.

Furthermore, the structure according to the invention is such that the means comprise a first feed path to the space, which feed path includes provisions, such as lateral openings or bars, so that undesirable matter, such as liquids or sand and the like, are diverted so as to prevent them from reaching the entrance of the safeguarding space, and that the means comprise a second feed path contiguous to the first one and adapted to be separated therefrom, which second feed path ncludes provisions for guarding the temperature and for exam ining the temperature of the objects, which means release the entrance to the safeguarding space when normal temperatures are detectecl and block the entrance to the space and give an alarm when deviting tempera tures are detected, the entrance being released upon restoration of the normal temperature. As stated above, the structure according to the invention ensures that the inserted object will never directly reach the safe but that it is guided through a barried guide chute (first feed path) to an examination chamber (second feed path). An inserted substance, such as liquid or sand and the like, however, will not reach this chamber, as the liquid, sand and the like will drain off through the bars before reaching the examination chamber.

This examination chamber is an air-tight space sealed by a cover and a bottom. In order to clear the entrance to the examination chamber as soon as an object is inser ted, the cover is removed at that movement. As soon as the inserted object has arrived in the examination chamber, which can be detected by means of a photocell, the cover will seal off the examination chamber. At that moment 2. time switch with time constant, for instance in the form of a piston with piston tube, is actuated, which permits the bottom of the examination chamber to be slid away after a predetermined, adjustable period of time, as a result of which the contents of the examination chamber drops into the safe.

When the inserted objects bums or is hot, however, the bottom will remain closed. This is ensured by a fire alarm, for instance a bimetal contact, mounted in the walls of the examination chamber, which fire alarm blocks the opening of the bottom of the examimation chamber by way of switching means. Only after the means according to the invention have released the path from the examination chamber to the safe and the deposit into the safe has taken place, consequently, the examination chamber is empty, the entrance is released for the insertion of a new object.

The invention will be elucidated hereinafter with reference to the drawings showing the structure in detail:

FIGS. 11-5 are elevational sectional views of an embodiment of the invention:

FIG. 1 shows the device in rest position with the examination chamber with closed entrance and open exit;

FIG. 2 shows the device with the entrance of the examination chamber open and its exit closed at insertion of an object.

FIG. 3 shows the device thereafter with the object sliding down the chute.

FIG. 4 shows the device after the object has been received in the examination chamber, its entrance and exit closed.

FIG. 5 shows the device retumed to its rest position, the object being delivered to the safe.

FIG. 1: in the rest position a slide a is maintained in the lowermost position by means of a spring v1 and a crank lever b so as to seal off the insert opening c. The so-called examination chamber e is closed at the top by the slide f which is pulled to the left by a spring v2. As spring v3 does the same to slide 3, the exit of the examination chamber to the safe is open.

A lamp 0 with photocell fc mounted in the wall of the examination chamber controls an amplifier v, as a result of which a yoke h remains in the position shown in the drawing. Control means 1 of time switch with time constant j has its maximal spring, as a result of which the crank lever m is urged in the position shown in the drawing against the spring action of v4.

FIG. 2: when an object is to be inserted, the slide a is raised so as to clear entrance 0. A dependent protective flap n can be pushed back by the inserted object. When the slide a is raised, the crank lever b simultaneously moves slide f to the right, as a result of which a time switch with time constant j, the time of which can be adjusted by a regulator k, is fully compressed. Slide g is entrained by slide f. In this situation the entrance to the examination chamber is open and the exit of this examination chamber is closed. The energized yoke h ensures that the entrance of the examination chamber remains open.

FIG. 3: after an object has been inserted and-the slide a is retumed to the closed position by means of v1 and crank lever b, the other members of the safeguarding device remain in the position shown in FIG. 2.

FIG. 4: as soon as the inserted object is detected in the examination chamber a by photocell fc as the light beam on the photocell is interrupted by the inserted object, h is de-energized and is tipped by spring v5, as a result of which the slide f can be pulled to the left by spring v2 so as to seal offthe entrance of the examination chamber. As yoke h blocks slide f in this position, no other object can be inserted since also slide a is blocked. This blocking takes place also if due to failure of the operating voltage or due to a faulty lamp 0 the release of the entrance to the examination chamber by slide f is prevented and the slide a is blocked in the closedposition.

FIG. 5: in this situation the time constant j slowly releases control means 11 to its maxima] spring. After the present period of time crank lever m will be urged baekwards so as to enable spring v3 to pull slide g to the left, as-aresult of which the exit of examination cham ber e opens and the inserted object can drop into the safe kl. However, this opening of the exit of the examination chamber can yet be prevented as, if a hot object has been inserted, a bimetal break contact bm is actuated so as to enable crank lever i spring biased by v6 to block the slide g. After restoration of the normal temperature of the inserted object, crank lever i can yet enable slide g to open the exit of the examination chamber to safe kl.

l claim 1. A device for depositing money or valuable objects and the like into a space for safeguarding these objects which comprises a first feed path to said space, said first feed path including provisions for diverting unde sirable matter, such as liquids or sand and the like, so as to prevent said matter from reaching the entrance of said safeguarding space, a second feed path contiguous to the first one and adapted to be separated therefrom, said second feed path including means for guarding the temperature and for examining the temperature of the objects, said means releasing the entrance to said safeguarding space when normal temperatures are detected and blocking the entrance to said space and giving an alarm when deviating temperatures are detected, said entrance being released again upon restoration of the normal temperature.
