KEY HOLDER AND PROTECTOR Filed April 13, 1940 Patented Aug. 19, 1941 UNITE D STAT ES OFFICE 2,253,332 KEY nonma- Aunxrltorrnoronl Robert E. Jackson, DedharmlMassi Application April 13, 1940, serialNo. 329,585 8 Claims. (Chm- 4 15) This invention relates to devices for containing keys and preventing unauthorized use thereof, and more particularly to the containing of house or apartment keys.

The principal objects of theinvention include the provision of a housing, having a combination other locked structure; the provision of such a housing having a drop shelf or drawer which contains the key and dropsupon proper Ina-.- nipulation of the combination; and the provision of a key holder and protector of simple design and effective in operation, having safety features to prevent unauthorized removal of the key or the holder itself.

Other objects and advantages of the invention will appear hereinafter.

Reference is to. be had to the accompanying drawing, in which Fig. 1 is a. front elevation of the device with drawer closed;.

Fig. 2 is a view similar to Fig. '1, but showing the drawer open;

Fig, 3 is a side elevation of the parts of Fig. 1;

Fig. 4 is a side elevation of the separable front element of the housing;

Fig. 5 is a rear elevation of the housing, look"- ing in the direction of arrow5 in Fig. 3;

Fig. 6 is a rear elevation of theparts shown in Fig. 4, and looking in the direction of arrow 6 in that figure;

Fig. 7 is a sectional View on line 1--1 of Fig. 2

Fig. 3 is a sectional view on line 8-8 of Fig.7; and

Fig, '9 is a detail view of a screwhead guard.

The numeral It] indicates a front plate having side flanges l2 and an inverted V-shaped The sides 26 of housing l8 provide guideways for the reception of a slidable drawer 28 which, however, is connected to the front plate ill for vertical sliding action thereon. The. bottom of the drawer part. way up the posts. The drawer 28, posts 30, and plate 34 are all made integral in one piece.

Plate 34 carries on itsv rear 'face a combination lock-36, the 'dials' 38 of which extend thru anap'erturefdll in the plate H] to the front thereof, so that they may be manipulated thru a.

hinged door 42 in the plate when the drawer is in up or locked position. A shelf 44 having two. depending hooks 4'6 constitutes a latch for the, lock, where when the drawer is up, and the hooks arejengaged', the parts are locked, and the front" plate ll! of course prevents access tothe key. A lip 48 extending forwardly from the, top of plate 34 prevents entire removal of the drawer 28' by engagement: with the bottom Qof the door opening in plate Ill.

" Plates 5i! are secured to the studs 32 by screws 152;;and screws ware rotatably mounted in these housing I3. is open, and the bottom of the draw er 28 closes the, same when the latter is in raised or locked position.

The drawer is enclosed on all sides except the front. Two spaced posts rise from the top of the drawer andform further guides for the drawer movement as they slidingly engage raised elements or studs 32 which are integral with the back of the plate l0. Between posts 30 there is a plate 34 extending from the top of Plates and'held' against axialmovement by nuts the bosses 22; so asto secure the front plate I0 to'the housing I8, When door 42 is open, the heads of screws 20 are revealed, and can be turned by a screwdriver.

The platesifl constitute an enclosure on plate to to retain the plate 34 and posts 30 and thus the drawer 28, so that tpgetherwith lip 48, the

drawer 28-, although slidingly mounted on plate it]; cannot 'be'removed' therefrom without removing screws 52 and plate 50 from the studs 32. These elements being on the rear of plate 10; it will be clear that the plate 50 cannot be removed without first removing the plate ill from the housing I8. 'Referring to Fig; -9, which shows the top part of-a plate 50; there is a pin 56 set into the -20-'in the relation shown in Fig. 9; The purpose orthis plate is to conceal" the heads of be apparenhand as a matter of fact, the screw heads'can be turned by a screwdriver only thru the door as will be apparent from the arrangementofthe-par-ts, as shown in Fig. 7. The plates 58 being "pivoted on the pin 56 may be swung up'to reveal the screw heads of the screws 20 by a person who isaware of their secret. Plates 5!! are cutaway at the corners as shown, in

order to avoid impinging on the screws 52.

The door 42 is, provided with bosses 60 which are apertured to receive hinge pins 62, and as seen in Fig. 7, boss .60. is curved. at. the edge of the door .to ride on the plate 34 when the door islswung. open. A pin or set screw 64 is mounted to project from the boss 60 and a cooperating slot 66 is provided in the plate 34 at a point Where the pin 64 will engage in the slot when the drawer 28 is in its upward-most position and when the door is open. However, if the door is unlocked and the lock is not engaged with its hooks 46, the drawer may descend.

In the operation of the device, the housing [8 is secured to any support desired by screws or bolts passing thru the slots 68 shown in Fig. 5, and then the completely assembled front plate Ill and drawer 28 are positioned within the housing so that the screws 20 aline with the threaded bosses 22. The drawer 28 is dropped, the hinge plates 58 are swung up to reveal the heads of the screws 20, and by simple manipulation of a screwdriver, the assembled plate and drawer are secured to the housing [8. The hinge plates 58 are swung into position to conceal the heads of the screws 20, the door 42 is shut, and the drawer 28 is thrust up from the bottom so as to engage and lock with the hooks 46.

It will be apparent from the above that the protective housing may be secured at some convenient location on the outside of a house or dwelling and the key to the house may be located in the compartment in the drawer. The device being locked, an authorized person knowing the combination may swing open the door 42, manipulate the dials of the lock to unlocking combination, and then upon closing the door and releasing the pin 64 from the slot 66, the drawer will drop revealing the key. In order to close and relock the device, it is only necessary to close the door 42 and push the drawer upwards into locking engagement with the hooks 46. The door can then be opened and the dials on the lock changed.

It will thus be seen that the present inventor has produced a key holder and protector which may be applied to any dwelling or building to hold the key for the same so that the key will never become lost or forgotten. This device is particularly useful for rental or sales agents who may have a great number of houses to show prospects and who must carry or maintain in their offices a great number of separate keys. By using one of these key holders for each of their houses, such an agent does not have to be equipped with a key for each house or apartment but merely has to know the lock combination, and he may thus obtain access to and show all of his houses or buildings without the necessity of carrying a great number of keys.

Likewise professional people, such as doctors, who are called upon to leave their homes at all hours of the day or night for emergencies will not be forced to stop to remember to take their front door key with them, simply by using the device disclosed in the present application.
