MAC HlNE FOR MARKING OR PRINTING MAIL-MATTER.

SPECIFICATION forming part of Letters Patent No. 464,704, dated December 8, 1891.

Application filed October 17, 1890- To all whom it may concern.-

Be it known that I, CHARLES BICKFORD, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Marking or Printing Mail-Matter, of which the following is a specification.

letters, postal-cards, and other like pieces of mail-matter to be marked or printed in such manner as to give the piece the usual postmark and stamp-canceling marks, in which the printing or marking mechanism shall be made operative by the movement of each piece of mail-matter into position to be marked, said mechanism remaining inoperative at all other times, so that there can be no operation of the ter is in position to be acted on.

The invention consists in the several improvements hereinafter described relating to an organized postmarking and canceling machine, or toa machine forprinting any desired marks on detached piecessuch as cards, envelopes, &c.for other purposes than postmarking and canceling-such, for example, as printing names and addresses on envelopes, printing business-cards, &c.

In the accompanying drawings, forming a part of this specification,Figure 1 represents a side elevation of a post-markingand cance1- ing machine embodying my invention. Fig. 2 represents a section on line 2 2, Fig. 1. Fig. 3 represents a section on line 3 3, Fig. 6, looking toward the left in the last-named fig- Fig. 4 represents a section on line 4 4, Fig. 1, and a plan view of the mechanism below said line. Fig. 5 represents a rear elevation of the machine; and Fig. 6 represents a section on line 6 6, Fig. 4, on a larger scale than the last-named figure. Fig. (5 represents a section like Fig. 6, but showing the impression-bed moved forward. Fig. 7 represents a section on line 7 '7, Fig. 6. Fig. 8 represents a modification. Fig. 9 represents a section on line 9 9, Fig. 4.

The same letters and numerals of reference indicate the same parts in all the figures.

In the drawings, or represents a horizontal bed or table which supports a pack of pieces I) of'rnail-matter, and is'provided at one end Serial No. 368,375. (No model.)

with a delivering-slot c, Fig. 1, arranged to permit the letter at one end of the pack to drop into a guide which is located below the table and is adapted to guide each piece as it falls from the table at until said piece strikes a tilting-table 23 below the guide and by its weight moves said table and sets in operation the mechanism which prints the postmarking and canceling characters on the piece and feeds the piece endwise to the packing mech anism, all as hereinafter described. The

guide dis here shown as composed of two ver 7 tical plates 10 10, the upper portions of which are curved outwardly, as shown in Figs. 1 and:

6, and attached by any suitable means to the-v supporting-frame of the machine, said curved portions forming an enlarged mouth-or ,en--.-' trance to the vertical space between said in passing along the descending side of the course of the belt, project through slots 2 2', Fig. 2, in a vertical plate j, which is ar ranged at one end of the table a, said teeth projecting through the plate j just far enough to engage the upper edge of the piece b at' the inner end of the pack on the table a and force said piece downwardly into the guide 01.

The pack of pieces is pressed toward the platej by means of a sliding follower it, im-' pelled by any suitable meansas, for exam- Said separator is composed of pie, by a weight Z, attached to a cord m, one

end of which is secured to a lug n on the follower k, said cord passing over pulleys 0 0 plate j is provided with an ear or lug p, which is secured by a screw q to a vertical wall a at one edge of the table a, Fig. 2, said earhaving a slot which receives the screw q, so that the platej may be adjusted to vary the project-ion of the teeth It through the slots in the plate j, and thus adapt said teeth to letters and pieces of different thickness. belt f is impelled in the direction indicated 9 below the table a, as indicated in Fig. 1. The

loo

by the arrow in Fig. 1 by power applied to I the lower pulley g, which supports it, through a shaft 0*, having a bevel-gear s, meshing with a bevel-gear t on said pulley, the shaft 0" being driven by connections with the main driving-shaft of the machine, as presently described. The pulleys g g are j ournaled in bearings suitably a'liixed to the supportingframe of the machine.

it represents a vertical shaft which is journaled in -fiXed bearings in the supportingframe of the machine and is provided with a head or carrier 1;, on the periphery of which are mounted the forms or printing characters which apply to the pieces b the desired post and canceling marks. One of the said forms or printing characters 10 is shown in section in Fig. 6. The head or carrier '0 is located so that the printing-form w thereon is caused by the rotation of the shaft to to project through an opening in one side of the guide (Z, as shown in Fig. 6, once during each rotation of the shaft u, and thus effect an impression upon a piece 1) within the guide, said piece being supported by a rotating bed 00, formed on a head m, which is affixed to a shaft y, located at the opposite side of the guide (1 from the shaft 10. The shaft is journaled in bearings z z in a slide or carriage .2, which is adapted to movehorizontally in fixed guides .2 .2 Figs. 2, 6, and 7, on the supporting-frame, said carriage and the shaft y being movable toward and from the shaft u to bring the segmental impression-bed 0c, aflixed to the shaft y, into contact with a piece of mail-matter that has been deposited between the two shafts and press said piece against the printing-form w on the shaft to. The shaft 20 is provided with an eccentric 12, which is engaged with one end of a connecting-rod 13,

the other end of which is provided with an elongated slot or opening 14, through which the shaft 1 passes, as shown in Fig. 7, the shaft being inclosed within said slot by a loose sleeve 15, which bears on the sides of the slot and turns with the oscillating movements of the connecting-rod. The slot 14 is considerably longer than the width of the sleeve 15, and is of such length that the reciprocating movements of the connecting-rod 13, caused by the rotation of the shafts a, have no effect upon the shaft y and carriage 2 until a plug or key 16 is forced into one end of the slot 14 by mechanism set in operation by the descent of each piece b of mail-matter, as hereinafter described, theslot 14 being shortened, it were, by the thickness of the plug 16, so that the reciprocating movements of the connecting-rod are imparted to the shaft 'yduring the time that the plug 16 remains in the slot 14. Theplug 16 is adapted to slide vertically between guides 15 on the sleeve 15, Figs. 3, (5, and 7, and is pivoted at 17 to one end of a lever 18, which is pivoted at 19 to an ear 20 on the connecting-rod.

21 represents a plunger adapted to slide vertically in a socket in the connecting-rod 13 and connected to the lever 18 at its lower end by a pin 22.

23 represents a tilting table, which is hung or pivoted at 24: to supports 24: on theframe of the machine and is nearly counterbalanced by a Weight 25, said weight being slightly heavier than the table, so that the swinging end of the table is normally slightly elevated, but is adapted to be depressed by the weight of the lightest piece of mail matter. The swinging end of the tableis under the guide d and below the printing-form and impression-bed, its location being such that when a piece of mail-matter has entered the guide and reached a position between the printingform and the impression-bed it will strike the swinging end of the table 23 and slightly depress the latter.

26 represents a light finger, which is pivoted at 26, Fig. 5, to an car on the table 23, and is normally held against the under side of said table by a spring 34, said finger moving with the table and being adapted also to move downward independently of the table. The finger 26 is arranged so that the depression of the table 23 will bring the swinging end of said finger into the path of rotation of an inclined or cam-shaped rib 27 on the shaft u, so that the inclined or cam-shaped under side of said rib will engage the finger 26 and press the latter downwardly upon the plunger 21. Said plunger is thus depressed and caused to in1part,through the lever 18, an upward movement to the plug 16 and insert said plug in the slot 14 in the connecting-rod 13.

The arrangement and timing of the described mechanism is such that the plug is inserted in the slot 14 when the connectingrod is at the endof its throw. (Shown in Fig. 6.) The insertion of the plug into the slot 14 causes' the connecting-rod in moving from the position shown in Fig. 6 to move the'shaft y and the impression-bed 0c thereon to the p0sition shown in Fig. 6, so that the impressionbed is caused to press the piece of mail-matter against the printing-form w and at the same time co-operate with said form in moving the piece endwise to a packing device, both the printing-form and the impressionbed being continuously rotated, as presently described. The return movement of the connecting-rod back to the position shown in Fig. 6 causes it to move the shaft y away from the shaft 'Lb, the plug 16 being at the same time released from the grip, which during the opposite movement of the connecting-rod held it between the sleeve 15 and the end of the slot 14, so that during said return movement the plug drops from the slot 14, its downward movement being accelerated by a spring 35, Figs. 6 and 6. The descent of the plug makes the connecting-rod once more loose, so that it reciprocates idly without moving the shaft y until the next piece of mail-matter strikes the table 23, when the above-described operation is repeated. It will therefore be seen that there is no operation of the printing mechanism until a piece of mail-matter is in position to be printed and that, after one printing opconnecting-rod. Said block 38 is in effect one oration the printing mechanism cannot operate. until another piece reaches said position.

To enable the impression-bed to adapt itself to the thickness of the different pieces of mail matter, I make the connecting rod slightly, elastic or capable of yielding, so that a piece of maximum thickness will not receive too great pressure between the form and bed. To this endl provide oneend of the connecting-rod with abox 36, containing a spring 37, which presses a block or plunger 38 against the plug 16 when the latter is-inserted in the end of the slot 14, and is enabled by the spring 37 to yield and thus permit the arrest of the lateral movement of the shaft 3 by the contact of the impression-bed with a piece of mail-matter when the connecting-rod is carrying the impression-bed toward the printingform before the completion of the throw or movement of the connecting-rod. As before stated, the shafts u y are continuously r0- tated, so that whenever the impression-bed 00 on the shaft y is brought forward and presses a piece of mail-matter against the printingform said bed and form serve also as feeding devices to move the letter or piece endwise away from the position it occupied when first dropped onto the tilting table 23. The rotation of said shafts maybe effected in any suitable way. I prefer to impart power to the shaft uand impart the same to the shaft 3 through the intermediate gears 28 and 29, the former meshing with a gear 30 on the shaft u and the latter with a gear 31 on the shaft y. The shaft r, which imparts motion to the lower pulley g of the belt or separator f, is provided with agear 32, meshing with the intermediate gear 29.

The pieces of mail-matter are moved by the described feeding action of the impressionbed and printing-form to a packing device,

. which consists of a series of vertical rows of guide cl and in position to receive a piece of mail-matter emerging therefrom at each operation of the impression-bed and type-form. The shaft or hub 41 is provided with a horizontal disk 42 below the said pockets, said .disk constituting a bottom for the pockets and supporting the pieces of mail-matter therein. The step-by-steprotation of the shaft or hub 41 causes thearms to move.

the pieces laterally in a curved path onto a table, which is preferably an endless apron 43, supported by loose rolls 44 44, the upper port-ion of said apron being just below the disk 42 and extending outwardly therefrom substantially at right anglesv to. the

guided. To said apron is affixed a vertical bracket 45, having a series of horizontal arms.

46, which project between the packer-arms 4O, said arms 46 collectively furnishing-a vertical support against which the pieces of mailmatter are pressed by the movement of the arms 40, said movement being in the direction indicated by the arrow in Fig. 4. A ver- -tical wall or guide 47, extending along one edge of the apron 43, projects through the arms 40, as shown in Figs. 4 and 9, its inner end being slotted to form fingers 48, Fig. 9,

alternating with the members of the rows of arms 40,. said fingers arresting the movement of the letters in the direction of the circular accumulated on the apron 43, said apron moving to permit the bracket to yield to the accumulation of letters. A pack of letters is thus formed on the apron 43, and said letters may be removed from time to time, as occa sion may require. The letters are kept in place on the apron by the bracket 45 at one side of the pack, the wall 47 at one end of the pack, and another wall 49, extending along the edge of the apron opposite thewall 47. The bracket 45 is yieldingly impelled or drawn toward the packing device by means of a weight A, connected by a cord B to the bracket, said cord running over a pulley O, as shown in Fig. 9. A spring may be arranged to perform this function instead of a weight, it being desirable to give the bracket at all times TOO a yielding pressure on the mail-matter moved against it by the packing device.

To prevent the band or apron from moving far enough to allow the bracket to pass over the outer drum 44, and thus permit the escape of letters at the outer end of the pack, I provide the apron with a downwardly-projecting arm D, Fig. 9, which is arranged'under the bracket and strikes the outer drum 44 when the bracket reaches a position over said drum, thus arresting the outward movement of the bracket.

The preferred means for rotating the hub or shaft 41 and its packing-arms are asfollows: A ratchet 50 is affixed to said hub or shaft below the packer and is. engaged by a pawl 51, which is mounted on the swinging end of a lever 52. Said lever is pivoted at 53, to a fixed support, and has a slot 55, Fig.4, which receives a pin 54, Figs. 4, 6, and 6, affixed to the slide or carriage z, in which the impression-bed supporting shaft is journaled. The movements of said carriage, caused as above described, oscillatethe lever 52 and cause it, through the pawl 51 and ratchet 50, I

ter or piecev moved out by the action of the printing-form and be d finds'a pocket in the packing device ready toreceive it. The backward movement of the packing device during the backward movement of the pawl 51 is prevented by a retaining-pawl 56, Fig. 4.

57 represents a fixed casing located above the packing device and supported by a fixed standard or bearin g 5 8, Fig. 5, passing through the hub 41. Said casing contains a train of gears 63, Fig. 5, the arbors of which project through the top of the casing and are provided with pointers or indicators 59, which rotate over dials 60 on the top of the casing. One of the said arbors projects downwardly below the casing and is provided with arms 61, which have downwardly-projecting pallets 62, which are arranged to be struck by upwardly-projecting pins 63 on the packing device. Each pin 63 in passing a given point strikes one of the pins 62 and gives a partial rotation to the arbor with which the pins 62 are connected. The gears 63 are formed so that the total number of movements of the packer will be indicated by the pointers 59 and the accompanying dials, the number of pieces passing through the machine being thus automatically counted.

The printing-form w is inked by means of an inking-roll 64, journaled on one end of a lever 65, which is pivoted at 66 to a fixed support and is normally held by a spring 67 in position to ink the printing-form. It is not desirable, however, to ink the form'when the latter is revolving idly without printing. Hence I provide means for automatically holding the roll out of its operative position,

so that it will not bear on the revolving form,

excepting when the latter is about to effect an impression on a piece of mail-matter. To this end I provide. the lever with an incline 69, which is acted on by a pin 68 on the lever 52. The contact of the pin with said incline when the impression-bed is in its retracted position holds the lever 65 in such position that the inking-roll cannot bear on the form; but when the impression-bed is moved toward the form the corresponding movement of the lever 52 causes the pin 68 to permit the lever 65 to be moved by the spring 67 into the position required to bring the inking-roll into contact with the form.

The printing-form is preferably made slightly eccentric, its ends projecting farther from the center of the shaft it than its central portion. This peculiarity of form compensates for the changes in the position of the impression-bed caused by the movements thereof toward and from the printingform, the bed moving slightly toward the form at the commencement of the printing operation and slightly away from the form during the closing part of the same. The eccentric shape of the printing-form enables it to make a uniform impression on the paper supported by the alternately advancing and retreating bed. The impression-bed may be made eccentric for the same purpose, and, if desired, both the bed and printing-form may be made eccentric, it being my belief that the latter arrangement will produce the best results.

The operation of the machine above described is substantially automatic, the only attention required from the operator being to place the pieces I) in position on the table a and to remove them from the apron 43. It is obvious, however, that the automatic separator shown in Figs. 1, 2, and 5 may be dispensed with and the letters separated from the pack and dropped into the guide (I by hand. WVhen this is done, I prefer to provide an automatic stop 70, Figs. 6'and 6, whichis pivoted at 71 to an car on one of the side pieces of guide d, and is normally forced by a spring 72 through a slot 73 in said side piece, as shown in Fig.6, so that it holds each piece of mail in the proper position for the action of the printing devices. On the upper side of the head or piece on which the impression-bed is formed is a rib-or cam 74, which is arranged to strike the stop and withdraw the same from the guide, as shown in Fig. 6, in time to permit a piece b, which has previously been arrested by the stop 70, to be moved forward by the printing devices.

75 represents a pin or stud attached to and projecting upwardly from the tilting table 23, the upper end of said stud being above the guide dandin such position that the operator can by pressing downwardly upon it depress the said table in case a piece of mail-matter dropped thereon is too light to depress the table.

a? represents a projection or counterbalance for the impression-bed, said projection being on the opposite side of the shaft y from said bed.

Itis obvious that various modifications may be made in the construction and arrangement of the devices and parts of the machine above described without departing from the spirit of the invention. For example, instead of employing the tilting table 23, I may use a fixed table 76, having a slot through which extends a projection 77 on a finger 78, said finger being pivoted at 79 and pressed upwardly bya spring 80, so that the projection 77 normally stands above the table 76. The weight of the falling letter strikes the projection 77 and depresses the latter and the finger 78, the latter being brought within the path of the cam 27 and caused thereby to depress the plunger 21.

The machine may be used for printing busi-- ness-cards, addresses on envelopes, Ave, instead of postmarking mail-matter.

It will be obvious that the positions of the printing-form and the impression-bed may be reversed, the form being applied to the shaft y and the bed to the shaft it, without affecting the essential principle of the invention, although in such case a different inking mechanism from that shown in the drawings would necessarily be employed.

For the sake of convenience I have hereinafter referred to the printing-form and its Ioo carrier and the impression-bed and its carrier as printing members.

The pressure of the spring 37, which permits the yielding of the impression-bed when the latter is in contact with the piece to be marked, may be regulated by means of a screw-cap 36, which is screwed upon the box 36 and supports the outer end of the spring, said cap being adjustable to compress or relax the spring, as the case may be.

It will be observed that the slotted vertical plate j, which supports the forward end of the pack of letters on the table (6 and receives in its slots the teeth h of the separator, being adj ustably secured to the wall a of the table a, as above described, enables the teeth or projections h of the separator to project to a greater or less extent from the supportingface of the plate j, and thus adapts said teeth to letters or pieces of different thickness, so that when running a pack of pieces of a given thickness the plate j may be adjusted to give the teeth a projection suitable for the thickness of said pieces, and when running thicker or thinner pieces the plate may be adjusted to give the teeth a greater or less projection.

The slot 0 is made adjustable to the thickness of the pieces of mail-matter, so that there will be no liability of two or more thin pieces being carried down at once. To this end I provide the table a with an adjustable slide a adapted to be moved to increase or decrease the width of the slot 0.
