15 Claims.

This invention relates to construction for mail boxes, particularly to mail boxes adapted for apartment houses or the like.

One of the objects of this invention is to provide a simple and thoroughly practical construction for mail boxes, particularly for that type of mail box in which a series of separate or private compartments is provided. Another object is to provide a compact and strong mail box construction in which the individual compartments may be rapidly and inexpensively constructed and assembled and in which the individual compartments may be dependably united into a single compact unit capable of being reliably and inexpensively mounted in place and capable of efiicient action under the varying conditions of practical use. Another object is to provide a mail box construction having great durability and great simplicity of manual actuation. Another object is to provide a mail box construction capable of being inexpensively built up to provide as many individual compartments as may be desired, and to provide a construction of the abovementioned character well adapted to meet the conditions of hard practical use. Other objects will be in part obvious or in part pointed out hereinafter.

ihe invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings in which is shown one of various possible embodiments of this invention,

view on an enlarged scale taken substantially along the line 7-7 of Figure 1, and

Figure 8 is a rear view of the assembled door unit.

Similar reference characters refer to similar parts throughout the several views of the drawmgs.

Referring now to the drawings, it is first pointed out that I have chosen to illustrate my invention in connection with a mailbox having three individual compartments, but I desire it to be understood that many features of my invention may be carried out where the construction embodies any other suitable or desired number of individual compartments. In Figure 1 I have generally indicated at 10 a mail box illustratively having three compartments generally indicated at 11, 12 and 13, as will also be clear from Figures 4 and 5.

Certain portions of each individual compartment are preferably of substantially identical construction; thus, the compartment 13, for example, is made up in part of a single sheet of metal suitably bent preferably at right angles to provide a rear wall 13a, a side wall 13b and an opposed side wall 130 (see particularly Figure 5). Similarly, compartment 12 is in part made up of a single piece of sheet metal shaped to provide a back wall 12a, a side wall 12b and an opposed side wall 120, while the compartment 11 is similarly provided with a back wall 11a, a side wall 11b and an opposed side wall 110.

Any suitable number of sheet metal members, shaped as above described, illustratively shown as three in number in the drawings, are then placed side by side so that adjacent side walls abut against each other flatwise. Thus (Figure 5) the side wall 13c of compartment 13 rests flatwise against side wall 121) of compartment 12, side wall 120 of compartment 12 rests flatwise against side wall 11b of compartment 11, and so on. These abutting side walls may be rigidly secured together in any suitable manner, preferably by spot welding at an appropriate number of suitable points.

Over the upper open ends of the thus alined compartments there is then placed an upper end closing wall member (see Figure 2). The member 14 is made of suflicient length to close the open ends of all of the alined compartments and is provided with a flange 14a bent downwardly so as to overlap the alined back walls 13a, 12a and 11a, the latter being secured to this flange 14a in any suitable manner, preferably as by spot welding. I V

The upper end wall member 14 is provided at its front end with a vertically directed flange 1412, the plane of the front face of which coincides with the plane of the front edges of the side walls 1317-430 of the compartment 13, l2b-12c of the compartment 12, and so on.

The lower open ends of the compartments are closed by a flanged sheet metal member 15 (Figure 2) having at its rear edge an upwardly directed flange 15a overlapping the alined rear walls 11a, 12a, 13a, etc. to which it is secured as by spot welding. The lower end wall closing member 15 has at its front end a downwardly directed flange 1519, the plane of the front face of which preferably coincides with the plane of the front face of the flange 14b.

The angular end sections of the members 14 and 15, produced by the flanges above desribed, even though of relatively light sheet metal, afford great rigidity and strength, which characteristics, by reason of their attachment to the several alined compartments, are thus given to the ultimate mail box construction itself. Furthermore, the substantially U-shaped cross-section of the sheet metal member out of which the back and the two side walls of each compartment are formed, is similarly characterized by great strength and rigidity.

The end members 14 and 15 are provided with suitably spaced openings into which flt ears formed as extensions of the upper and lower ends of the side walls of each compartment; thus, referring to Figure 3, ears 12c and 12/ at the upper end of the side wall 12b of compartment 12 and ears 12g and 12h at the lower end of the side wall 12b project through suitable openings in the members 14 and 15, respectively, and are bent over. Preferably the ears of the abutting side walls are alined and extend in pairs through the same opening through the upper and lower end members, being bent over away from each other, as is clearly shown in Figure 4. In the latter figure, ear 12) of side wall 120 and ear 11c of the adjacent abutting side wall 111) extend through the same opening in the upper wall member 14 and are bent thereupon in opposite directions. These ears form a strong and rigid mechanical connection between the ends of the side walls and the upper and lower end wall members and further strengthen and reinforce the resultant assembled construction.

The front open ends of the compartments ll, 12, 13, etc. are closed by a door arrangement in which the lower portion, preferably the lower half of the open end of each compartment, is closed by a separate or individual door and the upper portions, preferably the upper halves, of the front open ends of all of the compartments, are closed by a single door. Thus, referring to Figures 1 and 5, a lower part of the compartment 11 is closed by a door 16, the lower half of compartment 12 is closed by a door 1'7, and the lower half of compartment 13 is closed by a door 18. These doors 16, 17 and 18 are preferably made of suitably heavy sheet metal, preferably brass, and as is clear from Figures 1, 2 and 5, these doors are of such a width that the lateral and bottom edge portions thereof exactly overlie the front edges of the side wall members of their respective compartments and also the lower end wall member 15. In Figure 5 the door 18 will be seen to be of such a width as to be exactly received between the planes of the outer faces of the side wall members 1% and 13c of the compartment 13. And as is better shown in Figures 1 and 2, the lower end portion of the door 17 for the compartment 12 laps over the flange 15b of the lower end wall member 15 to an appropriate extent, preferably an extent commensurate with the thickness of the member 15 itself.

The upper portions of the compartments 11, 12, 13, etc. are, as above noted, closed by a single door, but this door is made up of individual door members 19, 20 and 21, respectively (Figures 1 and 4) for the compartments 11, 12 and 13, these door members being joined together to move and to be controlled as a unit. Each of the door members 19, 20 and 21 is proportioned with respect to the respective compartments with which they coact substantially similarly as are the individual doors l6, l7 and 18 above described, and like the latter are preferably of sheet metal of suitable weight and are preferably of brass. Moreover, the individual doors 15, 17 and 18 are preferably of identical construction, while the individual door members 19, 20 and 21, etc., are preferably also of substantially identical construction.

The door members 19, 20, 21, etc., having their adjacent side edges abutting, are secured -together to move as a unit by peculiarly advantageous features of construction. Extending across the upper portion of the door members, but slightly spaced from the alined upper edges of the latter, is a strap 22 of metal, preferably iron (see Figures 2, 3 and 8). This strap member 22 is better shown in Figure 8 in which is shown a rear view of the assembled door unit. The strap member 22 may be secured to the alined door members 19, 20, 21, etc., in any suitable manner, for example, by riveting, but preferably by welding.

Spaced downwardly from the strap member 22 by a distance, the appropriateness of which will be pointed out hereinafter, is another strap 23, also preferably of iron and extending across the rear face of the several door members 19, 20, 21, etc. Strap 23 is secured to the several door members in substantially the same way as is the strap 22. The left-hand and right-hand end faces of the straps 22 and 23, as seen in Figure 8, terminate short of the left-hand end edge of door member 21 and of the righthand end edge of the door member 19, respectively, by a distance substantially equivalent to the thickness of the side walls 131) and 110, respectively, the intermediate side walls of the several compartments being cut away, as is indicated in Figure 3, at 12p and 12q to accommodate the cross straps 22 and 23, respectively, when the upper composite door is closed. The above-mentioned left-hand and right-hand ends of the strap members 22 and 23, when the composite door member is closed, preferably snugly fit in between the side wall 13?) of compartment 13 and the side wall 110 of compartment 11, and thus aid to snugly fit the composite door in place and to hold the individual door members in proper position with respect to their respective compartments.

Considering now the manner in which the lower individual doors and the upper composite door member are mounted in position, I prefer to employ a hinge construction generally indicated in Figures 1, 2 and 8 at 24; this hinge construction coacts in a peculiar and highly advantageous way with the various features of construction hereinabove described. The hinge 24 includes a hinge plate 25 (see Figure 8) extending across the rear faces of the door members 19, 20, 21, etc. and adjacent the lower ends thereof, The hinge plate 25 is rigidly secured to these door members preferably in a manner more clearly described hereinafter and thus coacts also with the cross-straps 22 and 23 to make a strong, durable and solid single door unit out of the several door members 19, 20, 21, etc.

The hinge 24 is provided with as many hinge plates, coacting with the hinge plate 25, as there are lower doors 16, 1'7, 18, etc. in the construction and as is better shown in Figure 8 there are provided hinge plates 25, 2"! and 28 for the doors l6, l7 and 18, respectively.

All of the hinge plates of the hinge 24 are provided with spaced loops (as is better shown in Figure 2) the loops of the hinge plates 26, 2' 7, 28, etc. preferably alternating with the loops on the hinge plate 25 and being interfitted therebetween, as is clearly shown in cross-section in Figure 5, the thus alined openings in the loops being adapted to receive a hinge pin 29 preferably of a suiiicient length to extend across all of the several compartments of the construction.

Moreover, the hinge 24 is cut away, preferably only in the looped portions thereof, at a suitable number of spaced points indicated in the drawings (see Figure 8) as at 30, 31, 32 and 33, these points coinciding substantially with the midpoint of the side walls of the several compartments (see also Figure 5). Into these cut away portions are inserted what may be termed hangers shaped substantially as indicated at 34 in Figure 3. These hangers are preferably made of sheet metal and may be inexpensively stamped to provide a substantially rectangular shank 34a and an apertured ear 3412, the latter being rounded and shaped to match the exposed rounded contour of the loops of the hinge. These hangers 34 are alined with the looped portions of the hinge plates and the hinge pin 29 threaded through both the loops and the hangers 34, the extreme ends of the hinge pin 29 (with a hanger 34 on each end) being then suitably headed-over to hold the parts in assembled relation.

The hangers 3-4 are secured to the side walls of the several compartments in any suitable manner, but I prefer to'form what are in effect sockets to receive the shanks 34a of the hangers 34. This preferred construction I am enabled advantageously to carry out by stamping or pressing the sheet metal of the side walls of the several compartments into appropriate shape. As is best shown in Figures 1 and 5, the side wall members of each compartment are depressed inwardly to form a lateral or inward depression of substantially the dimensions of the shank 34a of the hangers 34; these depressions are indicated generally at 35, it being noted that there is thus formed between contiguous side walls of adjacent compartments a socket into which the shank 34a neatly fits. This socket is clearly shown in plan view in Figure l with respect to the side walls 121) and 130 and is shown in horizontal cross-section in Figure 5 with respect to the contiguous side walls 11b and 12c.

The shanks 34a of the hangers are fitted into these pockets or inwardly pressed portions of the side walls and are welded to the latter; the hinge 24 is thus dependably secured in place against bulging or warping and, moreover, reacts upon the side walls of the several compartments to dependably hold them against being forced out of alinement. The hinge plate 25, which as above noted extends across the door members 19, 20, 21, etc., as well as the continuous hinge pin 29, dependably coact with the hangers to achieve such advantages as have just been noted.

It is to be understood that the assembly of the hinge parts and the door parts with respect to the compartments may be achieved in a sequence of steps other than those specifically above outlined. V

The side walls of the several compartments preferably are cut away as at 36 (Figures 2 and 3) to accommodate the hinge plates of the hinge.

The hinge plates are preferably made of brass and are secured to the brass door members 19, 2G, 21, etc. and doors 15, 1'1, 18, etc. by iron rivets indicated in Figure '7 at 37, the rivets being appropriately headed or shouldered as at 37a, the head end of the rivet being upon the inner side of the hinge plates. The openings in the hinge plates are preferably counterbored, as is indicated at 25a in Figure 7. While I may simply head the rivets over in the usual manner and achieve good results, yet I prefer to spot weld the joint or joints between the iron rivet 37, the brass doors or door members and the brass hinge plate or plates, causing such an intimate union between the iron and brass as to preclude removal of the rivet. Thus, in spite of the fact that it is exceedingly difficult if not impossible to weld brass to brass, I am nevertheless enabled to achieve the mechanical advantages of a welded connection between these parts.

Bridged across the horizontally extending. cross straps 22 and 23 and suitably secured thereto but preferably in the manner described below and upon the inside face of the composite door l920-21, is a lock generally indicated at38, The lock 38 is provided with a latch 39 coasting with a suitable opening in the upper end wall member 14; t -e latch is adapted automatically to spring into the opening in the wall 14 and is provided with any suitable mechanism whereby it may be Withdrawn by means of a key. A suitable opening is provided in the door member 20 through which projects a cylindrical extension 3801 of the lock casing and within which is mounted the mechanism for receiving a key, as is indicated at 40 in Figure l.

The lock 38 is intended to be actuated by the mailman to open the door unit 19, 20, 21, etc. to place the mail in the respective compartments and the mailman carries a special key for actuating the lock. Upon actuating the look by means of the key the door unit is swung downwardly in counter clockwise direction, as viewed in Figure 2, and about the hinge pin 29 as an axis. Upon the rear side or" each door member 19, 20, 21, etc. is secured a sheet metal rack 41 (see Figures 2 and 8) of any suitable construction and adapted to receive a name card 42. These name cards are intended to identify the parties whose mail is to go in the corresponding compartment and as is better shown in Figure 8, these name cards are placed in the card panels or racks 41 upside down. When the upper door unit is swung downwardly as above described, these name cards are exposed to the view of the mailman but are right side up. Moreover, it will be noted that they are thus positioned where they are not obstructed by mail matter as is usually the case if the name panels are mounted upon the back walls of the various compartments.

The lock or lock casing 38 is preferably (18 tachably secured in place and a suitable number of screws 43, shown illustratively in Figure 8 as four in number, pass through the lock casing and are threaded into suitable threaded openings in the upper and lower cross straps 2223 and in the door member 26, as is better shown in Figure 6. The threaded ends of the screws are recessed or hollow, as is indicated at 43a, and this recess may be formed by simply drilling a hole axially into the end of the screw. Over the front face of the door member 20 is riveted, as by rivets 44, a plate of sufficient expanse to amply overlap the openings in the door member 20 through which the recessed ends of the screws 43 are exposed. These rivets 44 are of appropriate strength but are so attached that their outer or exposed heads may be readily enough knocked off as by means of a chisel and hammer.

In case the lock mechanism becomes inoperative, the proper representative of the postal authorities knocks oil the heads of the rivets 44, removes the plate 45, and then by means of any appropriately tapered tool inserted into the recessed ends of the screws 43 unscrews the latter, permitting the lock 38 to drop off of the cross straps 2223, whence the upper unit can be opened, the defective lock repaired or replaced by the same screws, the plate 45 riveted in place again, whence the apparatus is restored for normal use.

Each of the doors 16, 17 and 18 is, as above noted, independently operable, and each is controlled by a separate lock mechanism, the lock with its casing being generally indicated (Figures 2, 5 and 8) at 46; each lock is provided with a bolt 47 adapted to be moved by the key operated mechanism into a suitable opening in the lower end wall member 15 (see Figure 2). A suitable aperture 48 in the door is provided to permit the insertion into the lock mechanism of an appropriate key.

Positioned adjacent the lock mechanism 46 and preferably immediately thereabove, is an opening 49 in each of the doors, this opening 49 being preferably of rectangular shape through which is adapted to be exposed a card bearing the name of the tenant or party to whom the particular apartment is allocated. In Figure 2 this card is shown at 50.

Considering now how the card 50 and the lock 46 are held in place, reference may first be made to Figure 8 of the drawings. Secured to the bottom of each door 16, 17, 18, etc., and resting fiatwise against the inner side thereof, is a sheet metal plate 51 secured as by riveting to the door. Out of this plate 51 are struck up a suitable number of ears 52, 53 and 54, having end portions extending substantially parallel to the door itself (see Figure 2). Upon these cars rests the lock casing 46 and is secured thereto preferably by screws 55 (see Figures 2 and 8), the plate 51 havinto also a suitable opening through which the round key-receiving portion of the casing passes.

The plate 51 is extended upwardly, as at 51a, to overlap the opening 49 in the door and at this extended portion it is stamped or pressed into substantially the same cross-section better shown in Figure 2, whereby a card 50 may be slid in between the plate portion 51a and the door 17 and over the opening 49.

The plate 51 is also bent at its right and lefthand ends to form guiding flanges 56 and 57, the latter having a shape substantially as indicated in the lower portion of Figure 3. These guide flanges 5657 are bent so that their free ends (the ends nearest the observer viewing Figure 8) are somewhat nearer together than their remote ends. the remote ends being spaced apart by a distance equivalent substantially tothe width of the compartment. Preferably these guiding flanges are somewhat curved, as is best shown in the lower right-hand portion of Figure 5.

Upon closing any of the lower doors, these guide flanges 56-57 guide and hold the lower or free end of the door exactly into a position where it overlaps the front edges of the side walls of the corresponding compartment and they thus coact with the hinge construction above described to prevent a door overlapping or jamming against either or both of the adjacent doors.

Referring now to Figures 1, 2 and 5, suitable frame members 58, 59, 60 and 61 surround or frame the upper door unit and the lower individual doors, the frame members 58 and 60 being suitably secured by angle iron members 62 and 63 (Figure 5) respectively, and the frame members 59 and 61 being secured to the flanges 14b and 15?), respectively (Figure 2).

The angle members 62-63 and the end members 14-15 may be made of sheet iron and the frame members 58, 59, 60 and 61 of brass, the latter being readily weldable as by spot Welding to these sheet iron members. Also, the sheet metal of which the compartments 11, 12, 13, etc. have their side and rear walls made is preferably of sheet iron, thus permitting ready spot Welding together of contiguous side walls.

Any desired number of complete boxes may be related together, as shown in Figure 2; adjacent end or side walls are appropriately apertured to receive a wooden spacer 64 reduced at its ends to fit into these apertures. A bolt 65 with washers 66 and 67 passes through the spacer 64, the latter being somewhat yielding permitting the abutting end or side flanges of adjacent boxes to be snugly brought and held together, as is indimind at 68.

The hinge axes 34 are preferably of brass to match with the hinge and hinge loops, the brass axes 34 being readily spot welded to the sheet iron side walls. Similarly, the plates 51 are preferably of sheet iron and may be readily welded in place to the brass doors, and the same is true of the name panels 41 (see Figure 8). The manner of welding together the brass hinge plates and the brass door members and doors I have described above in detail. Thus, it will be seen that I am enabled to provide a thoroughly practical mail box construction in which all of the exposed parts are of brass or other suitable metal, which may be polished or ornamented in any desired manner and present a neat and ornamental appearance while the unexposed parts can be made of less expensive material, such as sheet iron, tin, and the like.

It will thus be seen that there has been provided in this invention a mail box construction in which the several objects hereinabove noted, as well as many thoroughly practical advantages, are successfully achieved. It will be seen that the construction is of great strength and durability, is compact and is of thoroughly dependable, reliable and convenient action in practical use. Furthermore, it will be seen that there is no waste space and that even though the partitions intervening adjacent compartments are relatively thin, the various features of the construction make certain that the doors properly mate with and overlap these dividing partitions and, moreover, do so without interference of one door with an adjacent door. Furthermore, it will be seen that the construction lends itself to rapid and inexpensive manufacture and that the construction is well adapted to meet the varying conditions or hard practical use.

As many possible embodiments may be made of the above 'nvention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbeiore set forth as shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
