MARTIN C. SCHWAB, OF CHICAGO, ILLINOIS.

SYSTEM FOR COLLECTING AND DISTRIBUTING PARCELS.

Specification of Letters Patent.

Patented June 13, 1911.

Application filed December 27, 1909. Serial No. 535,224.

- To all whom it may concern:

Be it known that I, MARTIN C. SoHwAB, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have'invented certain new and useful Improvements in Systems for Collecting and Distributing Parcels, of which the following is a specification.

The present invention relates to that class of systems for collecting and distributing parcels, an example of which is shown and described in my companion application filed October 25th, 1909, Serial No. 524,499. The system described in said application has one or more conveyors, called sending conveyers by which all of the parcels from various points or places hereinafter called sending stations are carried to a point or place called the central station and there delivcred onto a conveyor called a collecting conveyor where they are assortedvand distributed to appropriate conveyors, called distributing conveyors by which they are carried and delivered at various distantly located points or places hereinafter called distributing stations and these may be classified as regular and special. The characteristics which are necessary in the several conveyors are fully described in my former application so that a full description of their construction is not necessary in this application, excepting as to some features that are not shown in said former application.

The fundamental object of the present invention is to conomize in the matters of space and laboi required in assorting the parcels and distributing them to the appropriate conveyors by which they are carried either directly to the regular distributing stations where they are distributed to the delivery wagons, or the like, or else to the special distributing stations whence they are ultimately sent to the regular delivery stations or elsewhere.

One of the principal differences between the present system and that of my former application is that the system shown in said application has but one horizontal collecting conveyor located at the central station while the present system has a plurality of such conveyors and accessories thereto necessary to accomplishing the object aimed at by the present invention. The peculiarities of the plurality of conveyors are that they veyers and portions of adjacent parts.

are located in proximity to each other with a view of oconomizing floor space and to permitting an attendant to pass parcels from one conveyor to the other. Also, they are substantially parallel with each other in the sense that they are movable in substantially parallel directions, and are endless in the sense that each is in the form of a complete circuit through which the parcel may be carried one or more times until it reaches and is ready to be removed by the proper attendant. Also, they are located at substantially the same horizontal level so as to be within convenient reach of the attendant. Also, one is located within or is surrounded by another, in the sense that the outer one surrounds a common imaginary vertical line.

It is desirable, in order to obtain the highest attainable advantages of the system that the collecting conveyors have all of these peculiarities but it will be understood, of course, that these are separate features of the invention and any of them may be omitted in instances where it is not desired to avail of the advantages incident to them. The parcels are delivered onto the collecting conveyors by a plurality of sendin conveyors and when removed from the col ecting conveyersiby the attendants they are delivered -on to the receiving ends of a plurality of distributing conveyors which are located in proximity to the collecting conveyors in the respective relations hereinafter fully described.

The invention consists in the features of novelty that are hereinafter described with reference to the accompanying drawings, which are made a part of this specification and in which:

. Figure l is a diagrammatic view of a collecting and distributing system of simple form embodying the principal features of the invention.

Fig. 2 1s a plan view, largely diagrammatic,

of the endless collecting con- Fig. 3 is an end-elevation thereof viewed in the direction of the arrows 3, Fig. 2. Figs. 4 and 5 are views similar to Figs. -2 and 3, respectively, of a system of modified form embodying the features of the invention shown 1n Figs. 1, 2 and 3, and some additional. features. Fi .6 is a vertical section of still another mod ifi'cation. Figs. 7 and 8 are, respectively, a plan and vertical section of fragments of a system of still another modification this being elected as the preferred form, for the purposes of this application.

A represents the central station, B, B, etc., the sending stat-ions, C r'egular delivery stations, C the special stations, respectively, of which there may be any desired number located wherever desired, D, D etc. the sending conveyers and E, E etc., the distributing conveyers, all of which conveyers radiate or extend to points in proximity to the endless collecting conveyers, F and F, located at the central station. Each of the collecting conveyers comprises four parts, sections or divisions, f, f f and 7, respectively arranged in the form of a rectangle, and the several sorters and examiners have their stands or stations in proximity to suitable portions of these conveyers.

In my former application there was but a single sending conveyer extending from each sending station to the central station which delivered all of the parcels on to the single endless collecting conveyer so that all of the parcels passed within reach of each and possibly all of the sorters until each; parcel reached the sorter whose stand was within easy reach of'the receiving end of the appropriate distributing conveyer. In instances where the endless conveyer is of great length and a great many sorters are required an individual parcel may be taken from the endless conveyer and may have to be again-returned to it, and so on until it. reaches the proper sorter, and this represents a loss of space, time and labor. It is, of course, well known that the parcels handled are divisible into classes, according to the conditions under which they are sold or are to be delivered. For instance, some are aid for and are to be sent out by the regu ar deliveries: others are C. O. D. and are to be sentout by the regular deliveries: others are to be chargedandsent out by the regular deliveries, and others, falling in any of the preceding classes, are to be sent out by special delivery. According to the present invention these several classes may be separated and divided to any desired extent at each sending station and separately sent out to corresponding collecting conveyers. For the purpose of illustrating the invention, I have shown in. the drawings a sys tem having provision for thus separating and dividing the parcels at the sending stations and sending them to the central station in two divisions. One of these may include cash and C. 0-. D. parcels, which will amount to by far the greater part of the business and these may be sent from any sending-station to the endless collecting conveyer, F, by the sending conveyers, D The proper sorters stationed along this collecting conveyer will then remove the parcels and throw them directly into the receiving ends of the appropriate distributing conveyers, E, by

which they are carried to the delivery stations, C, where they are again assorted and thrown into appropriate delivery boxes or bins, 0. The other division may include pareels which' are to be charged and parcels which are to be sent out by special delivery, or both, or require other appropriate attention, and these will be sent from the sending stations by the sending conveyer, D, to the collecting conveyer, F. The special delivery parcels, if paid, will be thrown by the sorters stationed at the collecting conveyer, F, to the receiving end of the distributing conveyer, E, by which they are carried to a place or station C" appropriated to the special delivery of parcels by messengers or otherwise. The parcels to be charged are taken from the endless collecting conveyer, F, directly by an examiner stationed by it (in the system shown in Fig. 1)v and the account of the purchaser looked up. If it is found to be correct it is O. Kd and thrown on to the conveyer, F, whence it is taken and thrown on to the receiving end of one of the distributing conveyers, E or E! spcial delivery or regular delivery.

WVith one endless collecting conveyer located within the other it is necessary that the delivery ends of the sending eonveyers be located at difi erent levels in order that the sending conveyer for serving the inner collecting conveyer may cross and pass the outer collecting conveyer. Various arrangements for accomplishing this result will suggest themselves to those skilled in the art. In the drawings I have shown both of the collecting conveyers located in practically the same horizontal plane and I have shown the delivery end of the sending conveyer, D, which serves the inner collecting conveyer, as being located at a sutficiently high level to permit the parcels resting u on the outer collecting conveyer to pass. Beneath the delivery end of the sending conveyer, D. By reason of this difi'erence in the levels of the inner collecting conveyer and the delivery end of its sending conveyer an inclined chute, d, is arranged between them so as to guide. and direct the parcel from one to .the other, but this. chute must be considered as forming a part of the sending conveyer, within the meaning of the term conveyer as already defined. Guides 03" are used wherever they are necessary in order to guide the parcels in their transit from one level or from one direction of travel to another and are of the shape appropriate to the individual requirements, but in all instances when used they may be considered as a part of the conveyer, generally speaking. \Vhere the volume of business is comparatively small one exa'miner may be sufiicient to handle all of this special branch of the business so that while he is examining accordingly as it is to be sent out by one parcel the others may remain upon the inner conveyer and be carried around and around thereon until he is at liberty to handle it but this is not. feasible where the volume of business is very large and hence I have provided the somewhat modified systems. It should be understood that the invention is not limited to the specific proximity or relative locations of the several parts of the system to each other, excepting where this is necessary to a carrying out of the invention. With the system shown in Figs. 1, 2 and 3 it is proposed that the examiner or examiners, and possibly a sorter for disposing of special delivery parcels, shall stand in the space surrounded by the inner collecting conveyer, but where. the volume of business is large enough to warrant it, the system may be arranged otherwise.

In the system shown in Figs. 4 and 5, the distributing conveyer E for special delivery parcels crosses both the inner and the outer collecting conveyers'and extends practically the entire length of the inner conveyer so that all of the sorters stationed at the inner conveyer may throw special delivery parcels on to the conveyer, E. But this system contemplates the services of a large number of examiners and each of these examiners must havea desk or table equipped with the necessary reference books. For example, in Fig. 4 I have shown tables, (I, for as many examiners as may be required. The reference books are arranged alphabetically and divided into sets each including certain letters of the alphabet, as, for example, A to D, E to H, I to L, etc., and each of these sets is assigned to one of the examiners. The sorters stationed at the inner conveyer deliver the charge parcels on to the tables of the appropriate examiners and having examined and O. Kd them the examiners will dispose of them by deliverin them on to the outer collecting conveyer F, if they are to be sent out by regular delivery or directly on to the distributing (-onveyer E, if it is Within reach, or on to the inner collecting conveyer F, from which they are removed'by the sorter and by him delivered on to the distributing conveyerE if they are to be sent out by special delivery. ()n the other hand if they are not in condition to be 0. Kd, and require other special attention they are disposed of accordingly. The proximity of the sorters stands and the examiners tables may be such that the sorters may throw parcels directly on to the tables, (as shown in Fig. 6) but in seine instances the distance will be too great to permit this and in these instances a suitable number of distributing conveyers, H, are arranged with their receiving ends within convenient reach of the sorters and their delivery ends above the examiners tables which latter are to be considered as special distributing stations. Furthermore the parcels delivered on to the examiners tables may accumulate, but it is desirable that they should be taken up and passed upon by the examiners in the order in which they are received. To this end inclined chutes, I, are so arranged that the parcels from the conveyers, H, will fall upon and slide down them and on to the examiners tables so that the accumulation, if any, will be upon the chutes and the parcels will reach the examiners tables in the order of their delivery, and these chutes are to be regarded as parts of the distributing conveyers. It will also be desirable to provide suitable guide boards, J, in order to prevent the parcels while in transit from falling off of the conveyers and these may be of any desired or suitable construction and supported by any suitable means.

In some instances the examiners tables are double. That is to say, they are constructed and arranged so that one examiner may be stationed at each side and in these instances, each of the conveyers, H, is of sufficient width to serve one of these double tables. It is desirable, however, that the parcels for the two examiners stationed at the double table shall be kept apart and to this end a stationary dividing board, H, is arranged longitudinally over each conveyer belt and a. corresponding dividing board, I, rises from each of the chutes I. This constitutes what is the equivalent of a plurality of entirely separate and independent conveyers.

In Fig. 6 I have shown a modification in which the conveyers, H, are dispensed with. The special delivery distributing conveyor, E, is placed between the inner and outer collecting conveyers and the examiners tables, G, are placed outside of the outer endless collecting conveyer, F. This allows room within the space inclosed by the inner collecting conveyer, F, for the sorters to stand and, in addition thereto brings the inclined chutes, I, within such reach of the sorters that parcels for the examiners tables may be thrown on to them directly, without the intervention of the conveyers, H.

It will be understood that the inclined chutes may terminate directly at the top surface of the examiners table, or they may be continued to a vertical side wall, 9, thereof, but in any event they constitute parts of the tablesin the form of shelvesor platforms above the tops of the tables proper, on which the parcels will accumulate within easy reach and from which they may be taken one at a time by the examiner. This arrangement will also bring the special delivery distributing carrier, E, within convenient reach of the sorters.

All of the parts which are instrumental in carrying or conductin the parcels from the sending stations B and B to the collect ing conveyers F and F are to be considered as integrant parts of the sending conve ers,-

consideiedasja whole. .In the-form 0 the invention shown in Figs. 1', 2 and 3, these parts include spiral blades K and K arranged Within avertical tube K which extends to any desired number of floors, Where said tube .is provided with openings, k and is, at the sending stations, B and B, for the admission of parcels to said blades, inclined chutes, k and 70 which form continuations of the lower ends of the blades, K and K, anddeliver the parcels on to the delivery belts D and. D and the inclined chutes (l on to which the parcels are delivered by said belts and are in turn delivered on to the belts forming the divisions or sections f, f, of the collecting conveyers I and F, respectively.

In the system shown in Figs. 7'and 8 the several sending stations, B, B, etc., are located on the same floor and at each station is located a' wrappers desk or table, L, L, etc., having through its top two op'enings, from which chutes, D and cl", extend downward and through openings in the floor, terminatingdirectly over an endless belt, D", which is arranged horizontally in the room below and sufliciently close to the floor thereof to enable a wrapper to throw parcels on to the belt.. Suitably supported stationary ide boards, M, similar in function "to the guide boards, J, already referred to are arranged at the sides of the belt and a stationary dividing board, M, similar 'in function to the dividing boards, H, already referred to is suitably supported between the guideboards M, above the belt 1). The delivery end of the belt, D, is directly over the upper ends of two chutes, D and d,which are located one above the other, as appears in Fig. 8, the upper one of which is inclined downward and crosses the outer collecting conveyer, F, term nating at its lower end in proximity to the collecting conveyer, F, while the lower one is similarly inclined and terminates at its lower end in proximity to the outer collecting conveyer, F. Thus the wrapper at each station may divide and separate the parcels intended for the collecting conveyers, Fand F, and they will be kept separate throughout their transit. It will be understood that any desired number of wrappers tables may be served by one continuous belt which, together with the dividing board, M, becomes the function e uivalent oitwo separate conveyers and it will also be understood that the end table of the series will be located at the delivery end of the conveyer and with its chutes, D, (1, directly over the chutes, D, d, instead of over the belt. I

The drawings do not show details of the mechanism for supporting and driving the v conveyer,

several conveyers, but a propriate mechanism for this purpose will readily suggest itself to any one skilled in the art,

While the several conveyers for use in systems embodying the invention may be of any desired construction, still in the system shown in Figs. 7 and 8 a conveyer of the particular construction there shown is not only well adapted for this particular system, but it may be used in other systems.
