APPARATUS FOR SORTING, POSTMARKING, AND CANCELING MAIL.

Specification of Letters Patent.

Patented Aug. 17, 1920.

Application filed September 7, 1918. Serial No. 253,065.

To all whom it may concern Be it known that I, IVALTER H. Bowns, a subject of the King of Great Britain, residing at Greenwich, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Apparatus for Sorting, Postmarlc ing, and Canceling Mail; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel apparatus for facilitating the postmarking and cancellation of stamps on mail matter.

In post offices handling large quantities of letter mail the letters are usually placed in bulk on a sorting table, which is provided at one side with a plurality of longitudinal channels into which the letters are inserted edgewise by hand, the short letters being placed in one channel, and long letters in another, and the letters are discharged from said channels by suitable means, such as belts or conveyers into receivers wherein they are arranged or stacked side by side, preparatory to canceling same, the letters are customarily removed by hand from "the receivers and placed on the feed tables of automatic machines, which successively separate the letters, postmark them and cancel the stamps thereon. I will hereinafter refer to such postmarking and canceling machine as a canceling machine.

It has heretofore been attempted to run letters direct from the sorting table into such canceling machines; but these attempts have not been practically successful as it frequently happened that two or more letters would be bunched and passed simultaneously into the canceling machine and clog same; or one letter would telescope another before the canceling machine could act thereon, thus producing imperfect work, jamming letters, and causing annoying delays in the operation of the canceling machines.

The object of my invention is to avoid such objectionable and annoying occurrences and enable the letter to be automatically passed from the sorting table to and through the canceling machine without manual handling; thus greatly facilitating the operation of canceling the mail, and lessening the amount of manual labor required in so doing.

This invention is applicable to various types of present known letter sorting tables, and canceling machines, and as both of such machines are well known and familiar to those skilled in the art, I have conventionally indicated in the drawings only such parts of the sorting table and wanceling machine in connection with my improvements as will enable the invention to be clearly understood and adopted and used by those familiar with the art; and while I have shown one intermediate mechanism for directing the letters from the delivery end of the sorting table into the canceling machine, it should be understood that the invention is not restricted to the particular form or construction of parts or arrange ments thereof shown in the drawings, and that all such constructions and arrangements as come within the purview of the claims hereto appended are considered within the scope of the invention which I desire to protect.

In the claims I refer to a canceling machine, but intend thereby to include any mechanism for postmarking, stamping, or printing upon letters, etc. And by the term letters I intend to include any articles which can be operated upon by such canceling machine.

In the drawings Figure 1 is a diagrammatical plan view of parts of a sorting table, canceling machine, and the intermediate letter chute, as arranged and coordinated to operate in accordance with my invention.

Fig. 2 is an end elevation of Fig. 1 partly in section.

Fig. 3 is a detail view illustrating the use of the pusher plate after the sorting operation is completed.

The sorting table conventionally indicated in the drawings is shown as if having but one channel 1 into which the letters are inserted edgewise by hand, and they are moved endwise longitudinally of the channel and discharged therefrom by a suitable conveyer (such as an endless belt, 1") onto one end of a receiving chute 9 whereon they are stacked and moved facewise by a rotary stacker 3 which may be of any suitable kind, and operated by any suitable means so as to successively push the letters tacewise forward into and along the chute 2, as indicated in the drawing. The rear wall 2 of the chute forms a stop to arrest the letters e'ected from channel 1 and aline same.

The chute 2 is arranged adjacent and to one side of the end of the sorting table 1 at substantially right angles to the channel 1 and preferably sons to direct the letters rearwardly relatively to the table. To iacilit-ate the movement of the letters the chute may be inclined downwardly fromthe stacker so'that the movement of the'let ters in the chute is tacilitatedby gravity and 'they'will-notbe unduly compressed as they reach the discharge end of the chute.

If desired the movement of the letters longitudinally of the chute may be facilitated by'anydesired accelerating device or mechanism such as is commonly employed; 7

rating roller 5 and wiper 5 of the cancelmgma'chine which, being constructed and operating as usual, successively separates the letters from the stack on the table and passes them onto the marking and cancelingdevices (not shown).

By reference to Fig. 1 it will be seen that the delivery end ofthe sorting-table is to machine, so that the chute conducts the letters direct from the discharge end of the sorting table into the feed end of the canceling machine. I V

The canceling machine is preterably of the well k'nown Universal type, such as shown 'fo'r example in Patent #1,02-2,191 of April 2, 1912, and needs no further explanation herein. 7

The construction and operation of the sorting. table per seand of the canceling 7 machine per 8e are well known, and therefore do not require speclal or detailed explanation or illustration herein as any one familiar with the art will fully comprehend same.

The essentially novel feature of my invention is the relative arrangement of the sorting table, chute and canceling machine so that they are coordinated and coiiperate to first deliver the letters edgewise from the V discharge end of the table into the receiving end of the chute; then move the letters face wise lengthwise oi the chute, and deliver the letters directly from the chute to the feed table of the canceling machine, so that the letters are moved endwise from the stack in the chute into the canceling machine in such manner that no manual handling of the letters is required from the "time they are inserted into the channel of the sorting table until they arefinallytdischarged (after being postmarked and canceled) from the deliveryend of the canceling machine; and no letter shuntingor readjustingor repositioning devices are" required between the chute and sorting table, or between the chute and feed table. i

When the last letterhas been fed from the sorting table the operator may adjust the pusher plate" (Sfbehind' the lastletter in the chute, as indicated in Fig. 3; said plate 6 being'attached-to a slide 6 mounted on a' rod 6 and connected by a cord 6 -with a-weight 6 said' cord running over a guide pulley 6 so that the pusher plate acting under-the in fiuence of the weight tends to push the letters down thechute to" the canceling machine, and relieves theoperator of the duty of fe ding such letters to the canceling machine by hand.

Then the machineis operating--normally, however, the chute being full, the pusher plate'is swung out of the way to one side of the chute as-indicated in Fig. 1.

It will be seen that the letters are moved first endwise from the sorting table, then facewise along th'e'chute interposed between the overlapped ends of the sorting table and canceling machine, then again edgewise through'the canceling machine. Theletters arefed from the sorting table to the rear of the stack ofletters'in the feed chute of the one side of and overlaps or passes by the receivingend or feed table of the cancelingcanceling'machine; thus preventing clogging. After the chute is once filled the letters are automatically pestmarked and canceled between the manual operations of sorting the letters on the table and of removing the cancele'd and postmarked mail from the delivery end of the canceling machine"; and when the machine, the distance b'etween, the" stacker 7 wheel and the canceling machine feed table and the'inclination of the chute from the stacker wheel to the canceling machine teed table-being so regulated'and adjusted as to insure proper and'satisf-actoryfeed of the letters from the sorting machine to the cancelingfmachine.

The stacker wheel when properly-arranged and operated as described insures the pres entation of the letters against the feed rollers of the canceling machine in such manner and with such pressure that the feed rollers will properly act upon the letters and forward them to the markingand canceling devices. The stacker star wheel thus performs the function of a constantly operating pressing or feeding device to insure that the letters will be presented to the feed rollers of the canceling machine with sufiicient pressure to insure the proper action of the lat ter; and this is one of the important features of my automatic mechanism for handling the letters from the time they are dropped into the channel of the sorting machine to the final stacking of such letters in the canceling machine.

The invention is not limited to the specific features of construction nor the specific combination of parts illustrated in the draw-- ings; and is not intended to be restricted by the nomenclature herein to stamp canceling machines as it obviously is adapted for other uses than canceling mail; and the means for forwarding the letters facewise to and against the feeding devices of the canceling machine may be used in connection with the feed devices of a stampcanceling or other machine, independently of or apart from the sorting machine.
