Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed July 23, 1914. Serial No. 852,533.

the service of distributing and collecting. articles of food, clothing, merchandise, pareels, and the like.

More specifically, the invention contemplates the fulfilling of a long felt demand for a more suitable manner of conveying articles of food, clothing, parcels, and the like, from the exterior to the interior of homes, apartments, flats, room's, etc, and, at the same time, to provide an improved method of delivery of outgoing parcels, such as articles for the laundry, dye-works, and the like, for collection.

Great inconvenience has heretofore been attendant upon distributing supplies to the home of the consumer and collecting such articles as are desired to be returned for various purposes to the conveyor.

Such service has heretofore been rendered generally atthe danger of losingthe articles by theft, or under the inconvenience of having the conveyor enter the private domain of the consumer.

According to my invention the risk of loss by theft is eliminated, and the privacy of the consumers premises is preserved.

I provide, at a convenient point on the consumers premises, a cabinet or closet accessible from both the inside, and the outside of the premises. This cabinet may consist of one or more compartments, each of which is provided with suitable doors. This cabinet forms a seal, or look, for the reception or deposit of articles, and is a channel through which the various articles of food, clothing, parcels, etc., may pass.

One object of the invention is'to provide a collection or depositing cabinet, in which articles may be deposited, and through which articles may be transferred only in a predetermined direction.

Another object is to provide a cabinet service door having a plurality of compartments in which one or more of the compartments serve for the transmission of articles in only one direction and one or more of the compartments serve for the transmission of articles only in the other direction.

A further object of the invention is the provision of automatic locking means Which Wlll prevent successive opening of the same door, so that an article may not be deposited and Withdrawn from the same side of a given compartment.

A still further object is the provision of signaling mechanism to indicate automatically the occupied or unoccupied condition of a compartment.

The subject matter of this invention is a Special adaptation of the broader idea disclosed in my prior copending application, Serial No. 844,622, filed June 12,1914, and is, in some respects, a continuation thereof.

My prior application shows and claims an interlocking mechanism. However, the function of the mechanism in the present application is different from the one above mentioned.

In the said application, the interlocking mechanism for controlling the doors comes into action While one of the locking bolts is being withdrawn,-that is, the interlocking mechanism is effective only when one of the doors is open,-the function of the interlocking mechanism being to prevent oppositely disposed doors from being opened at the same time.

In the present application, the locking bolt I ofone of two oppositely disposed doors is always engaged by the interlocking detent, and prevented from opening until released. The locking bolt of the other door is completely disengaged from the interlocking detent and access can be gained to the interior of the cabinet through this door only. That.

operative or unlocked door, causes the interlocking detent to release the opposite door, and to engage the bolt of the door just operated.

I employ the term operating the door to mean an opening and closing thereof.

It can thus be seen that each door, after an operation thereof, becomes locked and can only be operated after the opposite door has been operated. In the drawings forming part of this application, I have illustrated a specific embodiment of my inven tion.

The invention is capable of wide application, and of a great variety of uses, and while one specific embodiment is herein described and shown, this description and illustration is intended in no wise to limit the scope of the invention, but is a description of an operative embodiment for the purpose of complying with the statutes.

In the drawings,

Figure 1 is a perspective view. of a door embodying my invention;

Fig. 2- is an elevation of the interlocking mechanism, part of the housing being sectioned on the line 2-2 of Fig. 3 to expose the interior arrangement of the several parts;

Fig. 3 is a View on the line 3-3 of Fig. 2;

Fig. 4: shows an elevation of the casing and lock with parts broken away, and the locking and detent mechanism in the position they assume when the compartment is vacant Fig. 5 is a view similar to Fig. 4 showing the parts in the position that they assume when a parcel or article has been deposited in the compartment, and the door closed.

Both Figs. 4 and 5 are views of the hall side of the cabinet;

Fig. 6 is a perspective view of the ratchet and cam mechanism which forms part of the interlocking mechanism, as will be described later.

I have found a particular advantage in locating the cabinet in a door structure. This is because of the fact that the door is always kept clear of articles of furniture on the inside, and, hence, is always accessible. The door naturally marks the location of the owners premises and is also accessible from the outside.

To illustrate the operation and utility o the cabinet service door, let it be supposed that the conveyer (milkman, grocer, butcher, laundryman, etc.,) wishes to deliver goods to the occupant of an apartmenthe will open the outside door to one of the compartments, place the parcel or package within the compartment and close the door. This door is now locked and interlocked to prevent eX- terior removal of the parcel from the compartment.

A second conveyer wishing to deposit an article or parcel is apprised by the indicator that this compartment is taken, therefore,

he employs one of the remaining compartments, going through the same routine as the first conveyer. The second door is thereby locked and interlocked, and the signaling mechanism indicates that the compartment is taken. In this manner all the available compartments in the cabinet may be filled by conveyers without disturbing the privacy of the apartment or of the conveyer coming into the presence of the housewife or servant within the apartment. \Vhenever the housewife or servant wishes to remove the articles deposited within the compartments, she may gain access by opening the corresponding door on the apartment side, the signal indicating which compartments contain articles and which ones are vacant. As the articles are removed, and the doors closed, the interlocking mechanism is automatically operated to release the bolt on the corresponding door on the outside of a given compartment. At the same time, the inner door is locked, and remains interlocked, until the outer door is again operated.

In order to provide a channel for outgoing packages and parcels, one of the compartments may be employed to allow of the operation of its doors in such a manner as to form an outgoing channel. In this case, a removable key or a simple combination lock may be employed on the outside, which key or combination is placed in the hands of the authorized conveyer.

In Fig. 1 I have shown a door 10 having the usual hanging and lock stiles, and top and bottom rails, but the space usually occupied by the panels and cross rails of the door is, in this case, occupied by the cabinet 11.

The cabinet 11 is securely fastened to the stiles and rails of the door and projects on each side thereof to form a symmetrical object. In the embodiment shown in Fig. 1, the cabinet comprises four compartments,

12, 13, 14 and 15, each having an outer door and an inner door for permitting access to the individual compartment. Each of these doors is provided with locking means 16, and adjacent each door is a sight opening 20, back of which a movable target bearing a legend is displayed. Similar locking means 16 are provided on the back side of the door and indicator openings adapted to display a signal are also disposed on the opposite or inner side of the door, similar to the ones shown on the outside in Fig. 1. Three of the compartments shown in Fig. 1 are for use as in-going compartments or channels, and the upper compartment 12 is to be used as an outgoing compartment or channel. The lock 16 for the compartment 12 is shown as different from the locks 16 of the other compartments, as it can be opened on the exterior to remove '7 objects from the compartment 12, while the remaining compartments cannot be opened to re- I move an object deposited in the corresponding compartment. "The lock for the compartment 12 may comprise a simple combination lock, or it may be otherwise guarded, as by a key in the hands of the conveyer.

In Figs. 2 to 6 inclusive, I have shown in detail the meansfor securing the alternate locking bolt 21 of each locking means 16 is provided with a socket shown, in Figs. 4 and 5, as a slot 22 through the body of the bolt. A. sliding rod 23 is adapted to engage the socket 22 of each of these locking bolts 21, in turn. When the rod 23, which forms an interlocking detent, enters the slot 22, the corresponding bolt 21 cannot be withdrawn and the door thereof cannot be opened. This provides, therefore, a suitable means for preventing opening of the door after a package has been deposited in the corresponding compartment. Further mechanism is provided for moving the rod into the socket 22 after the door is closed so that the object deposited in the compartment may not be removed by opening the door until some action is taken by the housewife or maid on the opposite side of the cabinet, which would necessarily occur when the object or parcel is removed. The movement that I employ is the operation of the inner door, as it is evident that the object or parcel cannot be removed without opening and operating the inner door. Hence, if means be provided for alternately moving the rod into the socket of the bolt of the door last closed, a complete cycle of operations will be insured, which cycle will be suitable for the purpose of insuring proper movement of the deposited article.

The rod 23 has a number of arms 24, 25 and 26. The arm 25 slides in a suitable guide 27 to prevent turning of the rod and also 'to operate the signaling mechanism, as will be later explained. The arms 24 aiid 26 are engaged by cam mechanism adjacent each one of the locking bolts 21. This cam mechanism comprises a ratchet portion 30 (see Fig. 6) and a disk portion 31 bearing the cams 32. The cam and ratchet structure is mounted on bearings 33, one of which bearings passes through an opening in the casing 34 and the other of which passes through an opening in a bracket 35 mounted on the casing 34. The ratchet portion comprises a pair of arms 36 and eccentric portions 37. A spring 38, mounted in the casing 34, bears upon the eccentric portion and tends to hold the arms 36 in the dotted-line position shown in Fig.4. When the arms 36 are in such position, one of these arms projects into'the path of the bolt 21 and,

. upon closing of the door and movement of the bolt to the locking position, which action is indicated in Fig. 5, the arm 36 will be rotated to such a position that the spring presses on the opposite side of the eccentric portion and snaps the arm structure into the full-line position shown in Fig. 4. This has turned the disk portion bearing the cams 32 through substantially 180 degrees and one of the .cams 32 will be brought into engagement with the rod 26 andwill force the rod 23 into the socket 22 of the corresponding bolt 21, as shown in Fig. 4, or as shown at the right of Figs. 2 and 3. The corresponding door cannot be opened, as it is impossible to withdraw the bolt 21 to release the same. Movement of the rod 23 to engage the socket in the bolt 21 has also caused actuation of the indicator or signal mechanism. The signal mechanism comprises a pair of targets 40, 41, adapted to be dis-.

played before the sight openings 20, shown more clearly in Figs. 1, 4 and 5. The targets 40 and 41 are connected by a pair of arms pivoted on the rod 42. This rod is supported by bracket 43, mounted in the casing 34. The arm 44 contains a slot 45 disposed diagonally so that movement of the arm 25 in the horizontal guide 27 will cause an angular movement of the arm 44 and a consequent movement of the targets 40 and 41 in and out of position back of the sight openings. A spring-pressed catch 46 holds the rod 23 at either end of its movement so as to prevent accidental displacement, as

by slamming of the door, or the like, and

consequent false operation. The locking means 16 may be provided with a fixed key 47 which is set into a countersunk depression 48 to avoid as much as possible any projecting parts on the door itself.

The operation of the mechanism above described in detail will now be set forth briefly: When the conveyer desires to deliver a package or parcel to the occupant of the room or apartment, he selects such compartment in the cabinet as he finds to be indicated as vacant by the target back of the sight opening 20 and opens the door thereof by turning the key 47. The bolt 21 slides back and allows the door to open. At this time, the spring 38 bearing on the eccentric portion 37 moves the arms 36 from the fullline position shown in Fig. 4 to the dotted line position in Fig. 4. The conveyer places the object or parcel to be delivered in the corresponding compartment and closes the door. Movement of the bolt 21 to the closed position causes engagement of the upper edge of the bolt 21 with one of the arms 36 not be opened.

and. as the bolt moves inwardly. the arm 36 is actuated to turn the eccentric so that the spring 38 bears on the opposite side and forces the structure into the full-line position shown in Fig. 4. At the same time, one of the cams 3:! has engaged the rod '34 and forced the same into the slot 22 of the locking bolt. The package or parcel is now locked in the compartment and cannot be removed from the outside, as the outer locking means 16 is held against operation. The movement of the rod '23 to engage the slot 22 has released the lock 16 on the inside of the compartment which contains the package. At the same time that the rod 23 was moved to the interlocking position. the signal was actuated to indicate on both sides of the cabinet that the compartment was taken." The housewife or maid can tell at a glance which one of the compartments contains an article and she may then open the door remove the object, and close the door. The operation of the parts in connection with the closing of the inner door is the same as described for the outer door. This leaves the inner door locked against opening and leaves the lock of the outer door in released position so that another package or parcel may be deposited. This description applies to the compartments l3, l-l and 15, as they are in-going compartments. The upper compartment 12 operates in the reverse order and is an out-going compartment, that is to say. when the compartment is empty, the outer locking means 16 is engaged by the interlocking detent and can- The inner door may be opened and an article deposited therein for out-going service and closing of the inner door releases the lock on the outer door so that the conveyer may have access thereto, and may remove the article, parcel, or the like. This compartment may be used for laundry. or the like, and furnishes a very convenient means for notifying the conveyer whether his services are required or not, as

he can tell by the position of the indicator whether any service is desired without making further inquiry.

It is apparentthat a great many modifications will at once suggest themselves to those skilled in the art and that the specificmechanism that I have illustrated is but one form of mechanism for securing the results which I have found desirable. All of these modifications fall within the spirit and scope of my invention and I desire the appended claims to be read with as broad an interpretation as possible, as I consider my invention to be broadly new. It is evident that the cabinet need not necessarily be mounted in a. door, but greater advantages are secured by so doing, as I have indicated. It is also apparent that a greater or less number of in-goiiig and out-going compartments may be provided and that a great number of variations of the structure may be made to suit individual conditions.
