This invention relates to an improved safety delivery receptacle and has for one of its principal objects the provision of a device by means of which milk in bottles and also other products may be delivered to a dwelling without disturbing the occupants and also in such a manner that the delivered products will thereafter be free from molestation or theft and also secure against the action of the elements, such as rain, frost or the like.

One of the important objects of this invention is to provide a safety receptacle for the delivery of various commodities, particularly foods or the like which can be readily incorporated, into the wall of a dwelling of any type, either old or new, and which will render the delivery of such commodities simple and easy without the necessity of any special locks or similar devices, while, at the same time, effectively preventing unauthorized disturbance of the delivered products, as by theft or the like.

Still another and further important object of the invention is to provide a means for delivery of milk or the like which will enable the housewife to conveniently gain access to the delivered articles, which, however, are securely locked against prowlers or others, and which, furthermore, will automatically unlock itself after the delivered articles have been removed, so that the apparatus is then immediately ready for further delivery operations.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawings and following specification.

The invention, in a p-referred form, is shown in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a front elevation of the improved safety delivery device of this invention, showing the outer door closed. l

Figure 2 is a view somewhat similar to Figure l, but showing the outer door open.

Figure 5 is a sectional View taken on theline 5 5 of Figure l, looking in the direction indicated by the arrows.

Figure 6 is a sectional view taken on the line E-S of Figure 3, looking in the direction indicated and showing the device in position for removal of the delivered articles.

Figure 7 is a detail view of the automatic locking and release element for the inner door, showing the same in unlocked position.

Figure 8 is a view of the same device, showing it in position to lock the inner door.

As shown in the drawings:

The reference numeral I8 indicates generally the outer framework of the improved safety delivery means of this invention, the same being adapted to be tted into a corresponding opening formed in the wall l2 of a house or the like, and provided with an outer door I4 mounted on hinges I6 and provided with an operating handle As best shown in Figure 2, the outer door I4 is adapted to be releasably held in closed position by means of the two co-acting parts I9 and 28 of a spring clip positioned just inside the door.

The apparatus may be made of any desired size, but is primarily designed for the delivery of milk, and therefore, preferably the interior portion thereof is of approximately a size to conveniently hold a quart milk bottle. The inner opening is also closed by adoor 22, which door is normally in shut position and operated from its front side by means of ahandle 24.

The inner face of thedoor 22 is best illustrated in Figure 3, the same being mounted onhinges 26, and alatching element 28 is mounted on the frame l0 below the door, adapted to maintain the door in locked position under certain conditions. The inner door is adapted to be releasably held in closed position by m'eans of aclip 30 similar to theclip 28 for the front door.

As best shown in Figure 5, thedelivery platform 32 is positioned behind the inner door and is mounted onhinges 34 for movement into an article delivery position as shown in Figure 6. Hingedbrackets 36 support the platform when it is in lowermost position, and these brackets are of sufficient strength to enable the platform to contain and safely support a considerable weight. Ahelical spring 38 is attached to theplatform 32 for the purpose of drawing the same into uppermost position, as sho-wn in Figure 5, when there is no weight on the platform.

An automatic latching element for theinner door 22 is provided, and, as already stated, comprises essentially alatch 28 which is mounted insuitable slides 44 on the frame l0 below therear door 22 and behind the same.

Mounted in a recess in the lower end of thedelivery platform 32 is a metal spring or the like 46 which is adapted to ride under the lower end of thelatching element 28, and as best shown in Figures 7 and 8, will push thelatching element 28 into uppermost position with respect to thedoor 22 when theplatform 32 is in lowermost position. This effectively prevents any rearward pushing of thedoor 22, and accordingly locks the same against unauthorized entry from without.

In operation, the milkman or other delivery l person, when making his rounds, opens the outer door I4, it being assumed, of course, that the delivery platform is empty and that the tension of thespring 38 has raised the same into the position shown in Figure 5, whereupon thelatch 28 will be in the position shown in this figure and in Figure 7. This, accordingly, leaves thedoor 22 unlocked. The operator thereupon, after having opened the door I4, pushes the bottle of milk or other commodity through the housing against theinner door 22. opening the same, and the action of opening this door will push thedelivery platform 32 downwardly about itshinges 34 into the position shown in Figures 3 and 6, after which the bottle of milk or other commodity is deposited on the platform.

Theplatform 32 is preferably lined with a metal plate or the like 50 so as to be more proof against wear and also to provide a more satisfactorily operating apparatus. The weight of one bottle of milk will be suicient to hold theplatform 32 in lowermost position against the tension of thespring 38 and thereupon the delivery man may insert more bottles or other commodities, placing the same on the platform. After the delivery operation is complete, thehandle 24 of thedoor 22 is grasped and the same closed, the bottom edge of thedoor 22 riding over the correspondinglybeveled face 48 of thelatch element 28, assuming the position shown in Figures 6 and 8. This closing action of thedoor 22 coupled with the downward movement of thelatch 28 is made possible because themetal cam element 46 comprises a leaf spring which is fastened in position by means of a nail orrivet 54, and is allowed to move downwardly a suffcient distance to allow the closing of thedoor 22 on account of a beveled edge or cut-awayportion 58 of the corresponding portion of theplatform 32, all as best shown in Figures 7 and 8. A lug orprojection 52 on thelatch 28 prevents the vsame from falling out of theretainers 44 and also limits the upward and downward action of this element.

The delivered articles are thereupon in a position to be readily removed by the housewife or servant, and after the last article has been removed, the tension of thespring 38 will cause thepiatform 32 to immediately resume its verti- ,cal position as shown in Figure 5, whereuponielatch 28 will fall by gravity into the position shown in this figure and in Figure 7, leaving the device in condition for a further delivery operation. Themetal lining 50 of theplatform 32 also insures against wear along the arc where the lower outside corner of thedoor 22 contacts the same when the door is pushed open and theplatform 32 accordingly moved downwardly.

It will be evident that herein is provided a safety delivery receptacle which will be quite a boon to milkmen and housewives generally and also other purveyors of food and` articles, which, if left outside upon delivery, are likely to be tampered with or stolen. The device of this invention eliminates the use of any special keys cessible to the housewife or servant.

cats or the like cannot possibly enter through the two doors and their locking means.

I am aware that many changes may be made and numerous details of construction varied throughout a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.
