3 Claims. (Cl. 340-281) This invention relates to mail delivery equipment and, more particularly, to a signal type mail box of the type disclosed and claimed in my copending application, Serial No. 76,540, filed December 19, 1960, for Mail Receptacle and Signal Therefor.

It is an object of the present invention to provide a mail box having manually initiated apparatus for energizing a signal in a remote location in response to the insertion of mail into the interior of the mail box.

A further object of the present invention is to provide a manually operated mail receptacle having an entrance slot for the reception of mail which is normally maintained in a closed position so as to prevent the entry of moisture, rain, and other foreign matter into the interior thereof, but which may be opened for the insertion of mail, during which opening operation, a remote signal is energized to signal the insertion of such mail for pick-up purposes.

An additional object of the present invention is to provide an extremely simple, substantially foolproof, and easily operated signal mail receptacle of the type described which can be manufactured in large quantities at a relatively low cost, and which can be readily installed in any desired location.

All of the foregoing and still further objects and advantages of this invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing, wherein:

FlGURE 1 is a perspective view ofa signal mail receptacle system made in accordance with the present invention in actual use;

FIGURE 2 is a perspective view, with parts broken away, of a signal lamp unit in an open position, and showing energization means made in accordance with one form of the present invention;

FIGURE 3 is an exploded fragmentary perspective view of certain parts of the assembly shown in FIGURE 2;

FIGURE 4 is a longitudinal cross sectional view taken along line 4-4 of FIGURE 1, illustrating a slightly modifled form of energization means;

FIGURE 5 is a transverse cross sectional view taken along line 5-5 of FIGURE 4;

FIGURE 6 is a perspective view of an electrical supply unit forming a part of the assembly shown in FIGURE 4;

FIGURE 7 is a fragmentary side elevational view of certain parts shown in FIGURE 4 in an actuated position;

FIGURE 8 is a schematic wiring diagram of the form of the invention shown in FIGURES 1 and 2;

FIGURE 9 is a schematic wiring diagram of the form of the invention shown in FIGURES 4 and 5; and

FIGURE 10 is an enlarged fragmentary perspective view of certain main operating parts of the present inven tion.

Referring now to the drawing, a mail receptacle system made in accordance with the present invention is shown to include a mail receptacle 15 having a main mounting plate 16 for attachment to a wall or other supporting surface, and having a closure 18 hingedly mounted thereupon by means of pivot pins 2th for movement between a normally closed position as shown in the drawing, and an open position, in which position the mail therewithin may be removed and the actuating parts thereof reset.

The top of the closure 18 is provided with a transversely extending mail receiving slot 22 which is normally maintained in a closed position by means of a flexible springtype plate 24 extending across the entire width thereof, 7

and guided for movement between the normally closed position and an open position by means of guide brackets 26 secured to the interior of the closure 18.

Mounted upon the lower end of the slide plate 24, are a pair of anchor brackets 28 secured to one end of a spring 3%). The opposite end of the spring 3% is secured to flanged brackets 32 of the guides 26, whereby the springs 30 normally urge the plate 24- toward the slot closing position shown in FIGURES 4 and 5.

A mounting pin 36 having one end formed into a handle and extending slidably through a vertical slot 35 in the closure member 18, is secured at its inner end to the bottom of the slide plate 24 and serves as a mounting for a depending push bar 34 having a transversely extending flange 38 for abutment with latch means hereinafter nized that downward movement of the mounting pin 36,

as shown in FIGURE 1, will effect the opening of the mail slot 22 for the insertion of the mail 42 therewithin.

A mounting block 45 is secured to the base of the mounting plate 18. A stanchion 46 is supported upon the block 45 and has a transversely extending pivot pin 5% pivotally supporting a latch lever 48 having a detent 52 at one end normally receiving a transversely extending portion of a control bar 54 connected to the actuating lever 56 of a two position switch 58. A tension spring 60 acting between the block 45 and the opposite end of the lever 48, normally urges the detent 52 at the opposite end of the lever into an engaged position with the control bar 54, thus retaining the switch 553 in a normally open circuit position against the action of the tension spring 62 tending to urge the lever 56 toward a position which will close the circuit through the switch 53. However, the lever 48 intermediate the pivot pin 50 and the detent 52, is provided with a transversely extending flange 64- which is in the path of downward movement of the abutmentflange 38 of the push bar 34, so that in response to downward movement of the pin 36, the abutment flange 38 will effect downward movement of the lever 48 through the flange 64, to release the bar 54 of the control switch lever 56, to allow the spring 6?. to move the switch 58 into a circuit closed position.

A first set of terminals 66 is mounted at one end of the block 45 for connecting a pair of leads 6% thereto that lead to a source of energy for energizing the system. Another set of terminals 70 is mounted at the opposite end of the block 45 for connecting a pair of leads 72 thereto which are connected at their opposite end to the base 74- of a lamp '76 mounted by means of a tongue 89 secured to the housing 78 of the base 74 for frictional insertion with a sleeve 82 of a bracket 84 mounted upon the interior roof of a housing 86 remote from the receptacle 15. This housing 86 has a light transmitting panel 33 provided with suitable indicia, facing the lamp 76, whereupon energization of the lamp 76 will illuminate the panel 88 to produce a visual signal in response to the closing of the circuit through the terminals 66, 7 6) connected to opposite ends of the switch 53 which is moved to a circuit closed position in response to downward movement of the pin 36 in a manner hereinbefore described.

In accordance with one form of the present invention illustrated in FIGURES 1 and 2 ofthe drawing, a transformer 90 mounted within the housing 36 will energize the lamp 76 from a wall receptacle, such as by inserting a male plug 94 of a connecting line 92. In the other form of the invention illustrated in FIGURES 4 to 6 of the drawing, an external source of power is eliminated in attain favor of an internal source of power in the form of a dry cell 96 mounted within holder 19.

It will now be recognized that an extremely convenient and effective mail reception has becn provided which will automatically illuminate the signal panel 88 at a location remote from the receptacle 15, immediately in re sponse to downward movement of the pin 36 for opening the slot 22 for the insertion of mail 42, or for any other purpose. Immediately upon release of downward pressure upon the pin 35, the closure plate 24 will return to the closed position, thus preventing the entry of foreign matter, or the like into the interior of the receptacle until the mail 42 is removed. The mail is removed simply by opening the closure 18 about the pivot pin 20 of the main mounting plate 16, thus providing access to the interior of the housing for removing the mail 42, and resetting the latch to the switch 58. If desired, a lock may be installed upon the closure 18 for preventing unauthorized entry into the interior of the mail receptacle.

While this invention has been described with particular reference to the construction shown in the drawing, it is to be understood that such is not to be construed as imparting limitations upon the invention, which is best defined by the claims appended hereto.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
