HOUSE MAIL-BOX.

SPECIFICATION forming part of Letters Patent No. 518,924, dated April 24, 1894.

Application filed July 18,1893.

To all whom it may concern:

Be it known that I, EDWIN FREDERICK KIN- sEY, of Washington city, in the District of Columbia, have invented a new and useful Improvement in House Mail-Boxes, of which the following is a specification.

The object of my invention is to provide a mail box to be attached at or near the front doors of residences, offices, or other buildlugs, to the face of a wall or in a niche specially formed to receive it, and which shall indicate to the mail carrier the presence of mail deposited therein by the occupants of the house, which shall indicate by a signal bell to the occupants of the house the deposit of mail by the mail carrier, and through the medium of which box also the purchase of stamps, stamped envelopes, and postal cards from the mail carrier in definite quantities may be effected and change made, and all without risk of loss of money or mail, as will be hereinafter fully described with reference to the drawings, in which- Figure 1 is a front and Fig. 2 a side eleVation of the box. Fig. 3 is a rear view with the back plate removed. Figs. 4, 5 and 6 are vertical transverse sections showing different positions of the parts. Fig. 7 is a vertical. longitudinal section taken near the front and looking from the rear. Figs. 8 and 9 are respectlvely a vertical transverse section and plan vlew in section of the stamp selling devices shown on a larger scale and Figs. 10, 11 and 12 are details.

In. the drawings A represents the body of the box, which is designed to be stamped up out of sheet metal, and to be attached to the front door or wall by bolts arranged within the casing so that the same are not accessible from the exterior, and the box cannot be surreptitiously taken off and carried away.

I will first describe the external features of the box which are directly manipulated by hand, and will afterward explain .the mechanism Within whereby the external features are made to co-operate with each other in carrying out the objects of my invention.

B is an end door hinged on a level with the bottom of the box, and provided with ahasp and staple with padlock for fastening the same. This door opens into the bottom of the box and gives access to the letters, 850.,

Serial No. 480,853. on model.)

- ient place in the house for the use of its occupants.

O is a drawer, which is trough shaped in cross section and slides in guides in a horizontal position near the top part and on the front side of the box. This drawer is designed to receive the letters, &c., deposited by the occupants of the house and intended to be collected by the postman, and also any money which may be placed therein in payment for stamps, postal cards, &c. This drawer is provided with a suitable lock, the key to which is held in the possession of the postman and fits the drawers of all other boxes.

D' is an indicator plate which bears the word mail, and is arranged to be elevated to the plain view of the postman by the act of the house holder in putting mail in the box, for the purpose of calling the attention {Of the postman to the fact that there is mail Waiting for collection. This indicator plate is raised automaticallyby the occupant of the house in depositing mail, or money for stamps, &c., and is released or dropped again by the act of the postman in collecting the mail or delivering stamps, &e., by devices which will behereinafter described.

E is the lid or cover, which is flanged around its edges to fit over a corresponding flange on the box to exclude rain, &c., and is hinged at its rear side. This lid is raised to give ,access to the interior both in the deposition of mail by the postman, and the insertion of mail by the occupants of the house.

F is the stamp selling casefwhich is affixed to the beveled upper front edge of the box, and is operated ashereinafter described.

To the lidE Figs. 4, 5and 6 there is pivotally connected on eac side a link E E which at their lower ends are in turn connected to a hinged lea hear the middle of its end portionsJThrsleafis hinged at its rear edge e to the stationary back plate of the box, so that when the lid E of the box is raised, as in Fig. 6, the linksE' lift and hold the leaf E transversely across, the box, so as to prevent access being had to the bottom of the box, and thereby preventing the surrep- ICO titious abstraction of mail already deposited in the box by the postman. When the lid of the box is raised for the insertion of the postmans mail, the leaf F. acts as a partition across the box to receive the mail, and then when the lid is closed this leaf drops and allows the mail to fall to the bottom of the box whence it can only be removed by the occupants of the house through the door Attached to the rear side of the leaf E is a wire E which runs through the back of the box to the interior of the house and connects with a bell or other signal which is rung by the lift of the leaf E when the postman deposits the mail, thereby notifying the occupants of the house. This wire E runs undera small grooved pulley E journaled in the back plate, and to prevent this wire from dropping away from the roller or getting misplaced a loop or keeper Ffof wire, see Fig. 12, is made to embrace the same. This pull wire I do not claim broadly in this relation as it is shown in my previous Patent No. 442,983, granted December 16, 1890, but I do not kn ow that it has ever been combined with a guide pulley and keeper as above described.

()rdinarily entrance into the top of the trough shaped drawer O is obstructed by a hinged and curved leaf 0 closing up against a lip 0 Figs. 4 and 5, but when letters are to be deposited to be collected and mailed by the postman, this leaf is deflected by the hand by pressing forwardly on its upper edge, as in Fig. 6, this leaf being hinged at the point 0 near its middle in the stationary end walls of the box. This curved leaf 0' is slotted as shown in Fig. 11 to give passage to the link bars E when the leaf is deflected as shown in Fig. 6. WVhen letters are thus inserted in the drawer for the postman notice is given to the postman by the automatic lifting of the indicator plate D, which I will now explain. This plate is guided vertically against vertical ribs cl struck up from the back plate, and rest upon a horizontal lip cl of the back plate, and plays vertically through the flattened tube d in the top of the box. At the bottom side of each end of the indicator plate there is formed a foot (1 which is arranged to be acted upon and lifted by the lift wings G which are formed on or attached to the ends of the hinged leaf 0, and project rearwardly at right angles to the leaf, see Fig. 11, so that when the hinged leaf 0 is deflected by the house holder in the act of depositing letters, to be mailed, in the drawer, this deflection of leaf (3 causes its wings O to lift the indicator plate D into view as in Fig. 6. The leaf 0 when released drops from gravity and the weight of the wings C and it is necessary to maintain the indicator in its elevated position. For this purpose there is at each end of the box a latch L fulcrumed at the point Z which is also lifted by the wings C through pin Z. The rear end of this latch rests under the foot of the indicator plate, Fig. 4, and when raised to its highest position the forward end of the latch is caught, Figs. 6 and 10, beneath a beveled face spring catch 0 on each end of the drawer C, so that although the hinged leaf 0 drops again after being deflected, the indicator plate is still held firmly in elevated position by the latch L as in Fig. 4. When the drawer 0, however, is pulled out by the postman for the removal of the mail, (in Fig. 1 it is shown partly so drawn out) the catches a are taken away from the latch L, and the indicator plate drops again to its lowest position upon the lip cl of the casing. This lip is formed by cutting and pressing inwardly a portion of the back plate, which leaves a slot in the back plate at this point. This is not only a convenient way of forming the lip, but it also makes a drainage slot and water shed that catches all the water that may enter through the indicatortube d and discharges it outside the box again.

I will now describe the stamp selling devices shown in Figs. 1, 2, 8 and 9. In the case F is arranged three (or more) endless chain belts F F F, Figs. 8 and 9, distended in parallel position along the horizontal upper edge of the box. I do not confine myself to any particular construction of belts but as shown each one of these belts consist of a metal body and a facing of leather or canvas marked with the denomination of stamps in different quantities, thus on belt F appears stamps 5 cents, stamps 10 cents,stamps 15 cents and so on. The next belt F will be marked for stamped envelopes in the same way, the third F will be similarly marked for postal cards, and so on for as many belts as may be used. The three classes named however, will be usually found sufflcient. These belts are to be set so that the kind and amount wanted will show through the glass covered window f in the case F, and money is placed in the drawer to. pay for them. These belts revolve around spiked rollers f'f f journaled in the case and are adjusted to the desired position by conical sprockets a. fixed on shafts a extending through the case and terminating in knobs a for turning them. These shafts are normally forced downwardly and outwardly by spiral springs a so that the sprockets are not in engagement with the chain belts until forced up against the tension of the springs. These shafts are locked against being thus forced up by a longitudinal bar G, Figs. 7, 8, and 9, which is pivoted or hinged at one end g, and at the other end is connected to a link G that descends to and connects with a lever Gr lying inside of the box near its front face. This lever is fulcrumed at g Fig. 7 near its middle, and its free end is normally held up by a beveled face lug g on the outlet door B for mail. Then this door is closed therefore the link G and locking bar G are drawn down and the bar G lying in front of the upper ends of shafts a prevents them from being raised, and hence the sprockets cannot act upon the belts. The result is that chil- IIO dren or unauthorized persons cannot change or tamper with the readings or indications which appear through the window f of the case.

Whenever, however, the door Bis opened by the occupant of the house, the free end of the lever G2 drops down, and the link G and locking bar G are raised. This locking bar is provided with three holes a 'of a size large enough to allow shafts a to protrude through them, and when the bar is lifted these holes pass into coincidence with the shafts, see Fig. 8, so that whenever the occupant of the house is present he may by'the opening of the door B set the stamp selling chains to indicate his want, and by leaving the money in the drawer the postman will deposit the proper stamps, postal cards,or stamped envelopes with proper change in the house holders compartment to be in turn received by the house holder.

After the postman has made the proper exchange the chains of the stamp selling devices will all be set to zero ora blank space again. This is effected through the tappet arms h carried by the belts which are struck and carried along to restore the belts to zero or ablank space by a hook or arm i on the drawer 0 Figs. 8 and 9 as the latter is manipulated by the postman. To permit this to be done without interference between the belts the spiked rollers and sprocket wheels of the belts are made of different diameters see Fig. 8, those at the top being larger and decreasing in size toward the bottom, so that the tappet arms h of the different belts lie in dilferent planes. These tappet arms all reach down to the range of engagement of the arm 1' which operates through a slot in the back of the case F, and for this purpose the arms of each belt are made longer than the one next below it.

In order that the sprocket wheels may pass into and out of engagement with the belts freely and without catching and hanging, the teeth of the sprockets may be beveled on the two sides which rub against the belt in going into and out of engagement therewith, and this, together with the yielding character of the belts, allows free engagement and disengagement.

To prevent any entanglement of letters or. mail matter with the working parts of thedevice, an inner lining Z of sheet metal is placed just inside the end walls and back of the case, so as to make a perfectly smooth throat for the passage of mail matter into the box. The shape of the end walls of the lining is shown at l234 in full lines in Fig. 4, and dotted lines in Fig. 6, and the back'of thelining as shown at Z in Fig. 3.

In constructing the drawer Oitis intended to be arranged to slide freely but so con-nected to the box that it cannot be pulled entirely out and disconnected from the box.

In constructing the lid E it is formed with a projecting lip e which is engaged by the back of the same hand of the postman that drops the mail, so that the postman in depositing the mail is only required to use one hand. This lip projects horizontally, extends the full length of the lid, and is made integral therewith. The downwardly projecting flange of the lid and the upwardly projecting flange on the box are also made quite deep, so that the lid has to be raised quite a distance before any opening of the box is olfered, so that the closure of partition leaf E and the ringing of the bell is certainly effected before any one could open the lid to rob it with a wire, or tamper with its contents. This I find to be necessary forthe reason that the slack of the signal bell wire, and the looseness of the connections will allow the lid to be raised far enough to permit the insertion of a wire, with.- out either ringing the hell, or closing the partition leaf. By making the flanges of the lid and box deep, and deeper in front than behind so as to accommodate the radial movement of the lid, a very considerable movement of the lid must be made before even a crack is afforded for the insertion of a wire, and this insures the ringing of the bell and closure of the partition leaf. 7

To accommodate the pivot pin of the link bars EQ'the upper edges of the end flanges of the box are notched or slotted as shown in Fig. 6.

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