MAIL-BOX.

SPECIFICATION forming part of Letters Patent No. '763,97 5, dated July 5, 1904.

Application led November 20, 1903. Serial No. 181,989. (No model.)

To MZ whom t mag/concern:

Beit known that I, CLINTON GRAY, a citizen of the United States, residing at Hammondsport, in the county of Steuben and State of New York, have invented a new and useful Mail-Box, of which the following is a specification.

This invention relates to improvements in mail-boxes, and particularly to that general type of boxes known as rural-delivery boxes, although many of the features of the invention are applicable to boxes employed for other purposes.

The principal object of the invention is to provide a novel form of mail-box with signals that will be automatically set when mail is deposited in the box and with signals that will be automatically moved from position when the mail is removed from the box.

Ai'urther object of the invention is to provide a mail-box in which the letter-receiving tray is provided with signal-actuating means.

A further object of the invention is to provide a mail-box having a pivotally-mounted mail-receiving tray provided with cams that serve as signal-actuating means.

A further object of the invention is to provide a mail-box with a pivoted letter-tray so arranged as to be positively moved to fullopen and full-closed position after the move-- ment has been started by hand.

A still further object of the invention is to provide a signal-actuating mechanism in which a portion of the actuating mechanism serves as a support for the door ofl the letter-box.

A still further object of the invention is to provide a letter-box having a false bottom in order to prevent deposited mail being injured from dampness.

A still further object of the invention is to provide a mail-box with a safety-catch which may be used in place of the lock or in addition thereto for the purpose of maintaining the door of the box in closed position.

A still further object of the invention is to provide a signal that will automatically alter both its size and character in accordance with the position to which it is adjusted.

Tith these and other objects in view the invention consists in the novel construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and particulary pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor detailsof the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure l is a perspective view of a mail-box constructed in' accordance with the invention. Fig. 2 is an end elevation of the same with the door of the box open to permit the withdrawal of the mail. Fig. 3 is a transverse sectional view of the box. Fig. 4 is a sectional plan view of the same, showing a pivoted tray. Fig. 5 is a detail sectional view corresponding to the upper portion of Fig. 3. Fig. 6 is a detail view of some of the parts shown in Fig. 5, illustrating the connections between the pivoted tray and one of the signals. Fig. 7 is a similar view showing the signal moved to front position. Fig. 8 is a detail sectional view through one end of the `pivoted tray, illustrating the pivoted connection between the tray and the box. Fig.` 9 is adetail sectional View through the door of the box, illustrating a construction of catch which may be employed to hold the door in closed position.

Similar numerals of reference are employed to indicate corresponding parts throughout the several iigures of the drawings.

The casing may be of any desired shape and in the present instance is provided with a bottom l,v a front wall Q, a rear wall 3,

end walls

4 and 5, and an inclined top 6. The lower portion of the front wall is provided with a rectangular opening 7 which may be closed by a door 8, hinged or otherwise movably connected to the casing. The Lipper portion of the front wall is curved outward and is in part formed by a pivoted tray 9, which may be moved to open position for the insertion of mail-matter.

The tray 9 is in the form of a substantially semicircular metallic sheet provided at its opposite ends with ianged disks lO, through the central portions of which extend screws or pins l1, carried by the end walls and serving as a pivoting means on which the tray IOO may be partly revolved. In the present instance screws are employed for the purpose of supporting the tray in position, and the disks are provided with -enlarged or thickened hub members 12, having threaded openings for the reception of the screws,and said screws are inserted from the outside of the casing, the screw-heads being afterward concealed by circular guard-disks 13, secured to the end walls and projecting outward beyond a vertical portion of the front wall. These guarddisks are provided with flanges to form a connecting means for the ends of the curved portion of the front wall, so that all the parts maybe rigidly secured together and access to the tray prevented except at the open front.

The outer edge of the tray is provided with a liange 14, serving to limit the movement of the tray in both directions, and said flange may be provided with a suitable operating'- handle 15, if desired. The flange serves as a shield or guard, so that'when in closed position it will prevent rain or snow from entering the box.

In order to assist in the opening and closing movements of the tray and to maintain the same in either open or closed position, a spring 16 is placed between the rear of the tray and the rear wall of the box, one arm of said spring being passed through a sleeve 17, carried by the rear wall of the box, and the opposite arm of said sleeve enters an eye 13, arranged on the rear face of the tray in such position that when the tray is in mid-position the spring will be substantially horizontal and movement in either direction will permit the expansive force of the spring and move the tray to full-open or full-closed position. The inner edge of the tray is provided with teeth or serrations 2O in order to prevent the withdrawal of a letter through the lower portion of the box. 4

In order to signal to the owner of the box on the deposit of mail-matter therein, I ernploy a signal 21, carried by an arm 22, that is secured to a rock-shaft 23, extending through one of the end walls of the casing, said end wall forming one support for the shaft, while the opposite is formed by a small bracket riveted or otherwise secured to the rear wall of the box. This signal may assume either of the two positions shown, and in one position movement is limited by contact of the lower edge of the signal proper with the roof of the box, while in the opposite or non-signaling position the signal engages the rear wall of the box. For the purpose of maintaining the signal in adjusted position I employ a weight 26, secured to the lever at one side of the center of the rock-shaft, the eccentric position of the weight making it effective in either of the two positions of adjustment of the signal.

On the rock-shaft are secured two

arms

27 and 28, that in the present instance are formed of a piece of sheet metal bent in such manner as to form two substantially radial faces, one at an angle of approximately ninety degrees from the other, The rear surface of the tray is provided with two

cams

30 and 31, which are also formed of sheet metal arranged one in advance of the other, so that the signal being in operative position opening movement of the tray will cause the cam 30 to engage the arm 27 and rotate the rock-shaft, moving the signal to an approximately horizontal position, and said cam will continue to hold the signal in this position until the second cam 31 engages with and operates the second arm 28, moving the signal to full signaling position, and so long as the tray is kept open it will be impossible for the signal to reassume the nonsignaling position. This signal is therefore operated automatically when the tray is opened to deposit a letter, and after the owner of the box has responded to the signal and removed the mail-matter he may drop the signal to the lowermost position, the tray at this time being closed.

In order to signal to the carrier that there is mail in the box awaiting collection, I employ a signal of the character shown in Fig. l. This signal is formed of two

members

30 and 31, hinged together in such manner that when moved to signaling position they will open to display the color and attract the attention of the carrier. In the present instance the main member 30/ is carried by an arm 32, pivoted to a stud or rivet 33 at one end of the box. The lower portion of the signal member 30, which may be approximately semicircular in form, is provided with a pair of openings 33 for the reception of eyes 34,

IOO

formed of an integral part of the signal member 31, the eyes being merely strips of metal forming eontinuations of the signal member and bent to form eyes of suitable size, the ends of the strips being riveted or otherwise secured to the member 31. The lower portion of the signal-carrying arm, adjacent to the pivot-pin of such arm, is provided with an angularly-bent portion that rests on a flange 36, carried by a lever 37, also pivoted to the stud 33, the flange being disposed on that side of the pivoted stud where the weight of the signal and its arm are disposed when in signaling position, so that the inclined portion of the arm may rest on the fiange to hold the signal upright. When the lever 37 is moved in the direction of the arrow, the flange is turned until the weight of the signal is turned beyond. or to the opposite side of the vertical line of the stud, and the signal then falls to non-signaling position, the signal member 31" folding automatically against the main signal member 3 and hiding a distinctive color, so that the attention of the carrier will not be attracted. When moved to upright or signaling position, the signal members will automatically open, and thus displaya distinctive color covering a comparatively large surface area.

The carrier-signal is operated automatically on theopening of themain door 8, and for this purpose the inner end of the door is provided with a projecting arm 39, that is connected by a link LiOto the lower end of the lever 37, excessive movement being prevented by extending the lever-connected end of the link beyond the pivot-pin and then bendingl jecting iiangc 45 in order to prevent the entrance of rain or snow to the box -when the door is open.

In boxes of this character, which are generally placed in exposed position, there is always likelihood of more or less moisture accumulating in the bottom of the box, and in order to prevent injury to the mail-matter insorted I employ a false bottom 46, formed of a sheet of wire gauze or netting having its ends and edges turned downward to form vertical supporting-flanges, by means of which such netting is maintained a slight distance above the bottom of the box.

In order to hold the door of the box in closed position, a number of devices may be employed. In the present instance there is shown an ordinary form of spring-lock 50, the locks being of dierent character on different boxes, so that the holder may gain access to the box, while the carrier is provided with amaster-key that will open any of the locks. In addition to this a spring-catch 51 may be employed to hold the door in closed position, and a safety-catch 52 may also be used either in connection with the main lock or as a substitute therefor. The safety-catch is formed of a vertically-slidable bar 53, to which is connected the inner end of a knob 54, extending through a vertical slot in the door, the knob being of suiiicient size to conceal the slot. The door is further provided with a projecting' stud 55, that may be in the form of a headed rivet, and said stud extends through a vertically-disposed slot 56, formed in the lower portion of the catch-bar. This forms a convenient means for locking the door in closed position and may be employed where key-opening locks are not considered, essential. i

It will be observed that all of the parts of the device are formed of sheet metal, and these parts may be die-struck and soldered or riveted together, so that economy of manufacture is assured.
