ADDRESSING-MACHINE.

-Specification of Letters Patent.

Patented Nov. 5, 1912.

Application filed October 5, 1909. Serial No. 521,156.

To ail whom it may concern;

lie it known that I DAVYDD C. HUGHES, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have in vented certain new and useful Improvements upon .\ddressing-Machines, of which the following is a full, clear, and exact description.

y invention relates to improvements in o'flice appliances and has special reference to printing and addressing machines.

The object of my invention is to improve the type inking devices of such machines and to substitute for the inking rolls and pads generally employed, an inking ribbon of the kind used on type writers.

Further special objects of my invention will appear hereinafter.

The several parts of my invention and the invention as a whole, hereinafter set forth in detail, will be readily understood by reference to the accon'ipanying drawings, which form a part of this specification, and illustrate the preferred form or embodimentof the invention. v

In the drawings; Figure 1 is a side elevation of an addressing machine embodying my invention; Fig. 2 is a plan view thereof; Fig. 3 is an end view of one of the type plates used in the machine; Fig. 4 is an enlarged sectional view of the retractive ribbonroll on the line A'A, of Figs. 1 and 2; Fig. 5 is a sectional detail on the line BI% of Fig. 4; Fig. 6 is a vertical, longitudinal section on the line C- C of Fig. 2; Fig. 7 is a plan detail,-with the printing roll re moved, to disclose the guard plate or envelop deflecting plate which overlies the ribbon;-

Fig. 8 is a sectional detail of the printing roll on the line DD of Fig. 2; and, Fig. 9

is a detail of the spacing block belonging to the printing roll.

I have chosen to illustrate my invention in connection with an addressing machine'of the kind disclosed in Letters Patent, 876, 913 granted to Russell N. Rogers, January 14, 1908, and more particularly to the machine disclosed in a contemporaneous application executed by said Rogers, to wit, Serial Number 521,115, of even date herewith. This is asmall compactvmachine adapted to be placed upon a deskor table and to be operated by a person standing or sitting beside it. It is of the class'in which address carriers or type plates are employed or used repeatedly with successive lots of envelops,

are capable of employment alone or in conjunction with less than the whole number of the mechanisms shown.

As will be understood from the following description, the invention is not confined to the specific structures illustrated in the drawings, as both the construction and arrangement of the elements and parts thereof may be readily modified without departing from the spirit of the invention.

, Ihemechai'iism which I have added to the Rogers addressing machine maybe employed upon other machines without important changes; to this extent it may be considered as complete in itself. But in an operative sense the mechanism necessarily includes printing or pressure means and the plate feeder and envelop mechanisms, where with it coacts to perform a complete printing operation. I shall, therefore, describe such coacting mechanisms in considerable detail, presenting same in the following order: The frame; on which all the other members and mechanisms are mounted. The rotary printing mechanisms by which the type are impressed on the envelops. The envelop holder; vhich is adapted to contain a supply of envelops. The envelop feeding mechanism; which automatically feeds the envelops one at a time from theholder to the printing mechanisms. The type plate magazine; which is adapted to contain a stack of type plates. The type plate conveyer; by which the type plates are removed from the magazine and conveyed to the printingmechanism. The type plate re ceiver; which receives the plates as they emerge from the printing mechanism. The type plate repacking mechanism; by which theused plates are rearranged or repack'ed in the receiver. The inking mechanism; for inking the type of successive plates.

The frame 'fOI' convenience is made in several parts, namely, the side frames, 1-1, having feet to rest upon a desk or table :a bottom plate or spreader 2:-a top or bed plate, 3:and two carefully alined lateral extensions, 4- The spreader, 2, which connects the lower parts of the side frame, is provided with a depressed, level, middle portion, 2, bordered by twoguide flanges, 2", and serves as a shelf for the plate container or drawer, 52. The rear end of the spreader is provided with upstanding flanges or lugs, 2, which are stops for the plate drawer. The bed plate, 3, occupies, preferably, a horizontal plane and is secured between the top rails of the side frames, 11. This plate serves as a support for the type plates in their movement from end to end of the frame, and its upper surface contains parallel grooves, 3, for the hereinafter describedconveyer belts or chain. These grooves, being of suflicient width, accommodate the plate propelling lugs on the conveyer belts; also the ribs of the type plates, as hereinafterdescribed. The edges of thebed plate, at the inner sides of the grooves, 8, act as guides for the type plates. The extensions, 94, provide the bearings for the several shafts of the printing and envelop feeding mechanism.

The printing mechanism has as its principal members, the rolls, 5 and 6. These are fixed upon the shafts, 7 and 8, respectively. The length of the roll, 5, slightly exceeds the width of the body of type on a type plate. The shaft, 7,.extends through, and has fixed bearings inthe frame members, 1 and 4; While the shaft, 8, is arranged in vertically movable spring pressed 'bearing blocks,'99, in the bearing pillars, 1 1 which permit the shaft, 8, and the roll, 6, to rise when a plate and envelop pass beneath. A space somewhat less than the'combined thickness of an envelop and a type plate, always remains between the rolls, 5 and 6. The shaft, .7, is ,rotated by means of a crank, 17, connected thereto by a one way clutch,

. 18', which prevents backward turning of the machine. The rolls, 5 and 6, should rotate at substantially the same peripheral speeds and the shafts, 7 and 8, therefore, are connected by properly proportioned gearing; preferably a train ofbeveled gears, inclosed in a two part "casing, 20;'shown in Fig. 2.

The bearings of the shaft, 8, are far enough apart to admit the widest envelop or sheet to be printed and allow itto pass between the printing rolls. The shaft, "8, parallels the top of the machine frame (the laterals) and, obviously, the opening, which extends from one pillar, 1? to the other, permits the side plates of the envelop holder.

printing of a sheet that is much wider than the length of the printing rolls, 5 and 6, adapting the machine to a wide range of work.

The envelop h0Zder.W' hen the word envelop is used herein, it is intended to include envelops, cards, sheets and the like. As these vary in size, from small envelops and tags to the largest wrappers and letter sheets in ordinary use, the envelop holder is made adjustable, to the end that it may be easily expanded or contracted, to suit the work in hand. It may be bodily shifted from side to side, so that the imprint of the type may be placed on any desired port-ion of the envelop or sheet, and is so constructed that the envelops may beplaced at difierent angles therein, as best suits the quality and nature of the paper. Referring now to the drawings, 22, 22, represent the wings or These plates have bottom flanges, 22 to give them stability; and the latter are freely slidable in the grooves, 23, of a long transverse bar, 28, supported at the ends ,of the laterals, 4.. The wings, 22, may be moved lengthwise thereof. After adjustment on the bar, the wings are secured by small set screws. The spacing of the wings or end plates closely corresponds to the width of the envelops for which they are guides. The envelop holder has two bottoms, 24 and 25, one (24:) which is preferably fixed, and the other (25) movable and adjustable. These bottoms are extensible and collapsible, to follow the movements of the wings, 22.

- The envelop feeding mec-ham'sm..1t is evident that the envelop holder may be used as a mere manual convenience in feeding envelops, one by one, to the printing mechanism; but such use is not intended; for, by the addition of a few simple parts upon and adjacent to thebar, 23, and shaft, 8, the feeding of the envelops is made automatic. The parts referred to, are two roll sections, 26, 26, on the shaft 8; certain rubber bands or peripheral surfaces, 27, thereon; several small projections or fingers, 28, on the edge of the bar,.23, and certain stop-and-release dogs, 29, arranged beneath the roll. The rolls, 26, are fixed on the shaft, 8, and are of substantially the same diameter as the printing or pressure roll, 6. On each of these rolls, 26, are two or more of the rubber bands, 27, which project from the surfaces of respective rolls, 26, and present peripheries of slightly greater circumference. The fingers or projections, 28, extend from the edge of the bar, 23, almost into contact with the parts oftlie upper roll. The rubber bands, 27, and the projections, 28, are usually staggered and present a feed gap or opening, which 'is lon itudinally waved or irregular. The efiect of this arrangement is that the first envelop which passes between the projections, 28, and the drawing suifaces, 27, of the rolls, 26, forces the second envelop back upon the tops of the projections, 28, so that only one envelop may leave the holder at a time. E represents in Fig. 6 the first envelop, and E the second envelop in the holder. Horizontal adjustment of the bar, 23, toward or from the adjacent roll sections, to alter the' feeding gap, is accomplished by turning the thumb wheel, 31. on the cam shaft, 31, which is joined to the bar by the hangers, 31. The vertical adjustment'of the bar is governed by the, thumb wheel, 30", on the shaft, 30 which works the supports of the bar, 23. During the use of the machine, the rolls, 5 and 6, rotate in the direction of the arrows; their adjacent surfaces moving forwardly. With proper adjustment of the envelop feed members the upper roll, (parts 6 and 26 inclusive) constantly engages the first or top sheet in the holder. The friction of the rubber surfaces, 27, of the roll upon the envelop or'sheet is greater than the friction between that envelop and the next. In

consequence the first or uppermost envelop of the pack, if free, will be drawn down by the rotating feed roll; and on the passage of one envelop, the roll will begin to act on the next. It follows that a continuous stream of envelops will be fed through the gap unless means are used to interrupt or intermittently nullify the action of the feed roll. As it is not-desirable to intermit the rotation of the upper or feed roll, and as the type plate feed,is intermittent, a' mechanism is used for momentarily staying or delaying the exit of each envelop, and holding it until a type plate arrives beneath it. Another -=purpose of the intermitting mechanism is to free each envelop somewhat in advance of the arrival of the type plate so that the imprint may be properly positioned on the face of the envelop, not at the end thereof. As better explained: The intermitting mechanism is adjustable so that the envelop may be freed at any desired moment before printing begins, which enables the operator to place the address on the envelop at that point which appears best. The dogs, 29, are the chief parts of this intermitting or hold back mechanism. As shown in the drawings there are several of these dogs, each z having an upturned or hooked end to work up and downheneath the upper roll. When raised, they stand in the path of the envelop and nullify the tractive effort of ,the

feed roll, holding back the end of the envelop. On the approach of a type plate the dogs are lowered and thus disengaged from the envelop, allowing the feed roll to pro pel the envelop forward. One of the dogs is over the roll, 5, and, to make room there for, the roll has the groove, 5 Other dogs may be located within the lateral, 4, which has an opening in its top, through which the dogs may work, as shown in Fig. 7. The

dogs are preferably formed on arms, 29, all

of which are fastened on a single rock shaft, 29 so that they may be worked simultaneously from a single point. A torsion spring (not shown) on the rock shaft, 29 normally holds the dogs in depressed condition, and a cam, 29, shown by dotted lines in Fig. 6, is employed for positively. raising the dogs and holding them in raised position until the moment for the release of the envelop. This constitutes the envelop timing mechanism. The cam shaft, 29, having the thumb wheel, 29, is ponnected with the dogs, and by means thereof the latter may be accurately positioned between the upper and lower members of the printing mechanism.

The type plate magazine appears in F igs 1. and 2. It is a structure which is secured in uprightposition upon the rear end of the machine frame and has stationary and movable members, 32 and 32, adapted to hold a stack of ty'peplates, P. Each type plate comprises a thin metal plate, P, having two relatively deep ribs, P, on its underside or back, the same being formed by crimping and folding the plate. The plates when stacked, as in Fig. 1, present their ribs downwardly, one resting on the other, and the ribs of each holding it off of the type on the other. The rear or upper edge, P of the plate is longer than the lower edge, P and arms, or ears, P, are formed on the ends of the plate. The plate is preferably wider than it is long, and the holding strips,

P, are arranged longitudinally on the plate.

The type,-.which I prefer shall be metallic,

ranged on the shaft 7, and are of such size that the tops of the belts are about flush with the periphery of theroll, 5. to prevent interference with the printing. The sprockets, 48, are placed on a shaft, 49, which is held in adjustable bearings, 50, at the rear end of the frame. The positions of these parts are such that the upper legsor reaches of the belts run smoothly in the bed plate grooves, 3. Obviously, the cdnveyer will be driven by the rotation of the roll, 5, and crank, 17, the top of the belt moving toward said roll. At intervals the belts are provided with lugs, 46, which run in he .of the roll, 5, adjacent to the ends thereof,

in position to receive the ends of a type plate as it emerges from the rolls, and adapted to deflect the plate and turn it downward into the forward end of the plate drawer, as shown in Fig. 6.

The type plate )"Gjfltr'fiidl'l":The function of this portion of the mechanism is to clear the lower end of the plate chute, (the deflectors) 53, so that one plate after another may fall into the drawer. This is done by pushing each plate backwardly in the drawer as soon as it falls thereinto. As shown, the lower parts of the plates fit between the sides of the drawer, while the ears thereon overhang the edges of the drawer and support the plates in inclined position therein. Riding on the edge of the drawer in'this manner, thef plates are easy to shift; even when the drawer has been nearly filled with plates. (The clearing, shifting. or packing mechanism is of simple, durable construction, comprising two bell cranks, 5-6, 56, joined by a rod, 56", and pivoted on the for ward ends of the machine frame. lower ends of the bell cranks are so positioned that when swung backwardly they engage the ears of the plate last to dro from the deflectors or chute, the bell cranrs being above and at the.sides of the drawer. The bell cranks are actuated by a lever, 57, pivoted on the side of the frame and itself actuated by an eccentric rod, 58, the strap of which incloses an eccentric, 59, located on the shaft, 7, at the end of roll, 5.

The inking mechanism.l employ an inked ribbon, R, to supply the ink necessary to imprint the-types of successive plates upon the envelops. This ribbon resembles a typewriter ribbon and as shown in the drawings, passes beneath the bar, 23, and through the constantly open gap or space between the printing rolls, 5 and 6. It intervenes between each type plate and envelop and at the time that they are passing through or between the printing rolls and the pressure of the rolls upon the type forces the ink from the ribbon onto the surface of the envelop, leaving the desired imprint.

The I from the machine.

difficulty and adapt the ribbon to move forward in eiract time with the plate and the envelop, from the instant that they come together until they part on the discharge side of the printing rolls, I mount the ribbon on two rolls, R and R one of which (R pays out the ribbon as required, while the other, (R takes u the slack. I prefer not to retract the ribbon after each printing operation. Instead of doing so, I arrange the ribbon to move constantly in one direction, namely, forward, until the magazine is emptied of plates, and. accomplished the retract-ion or rerolling of the ribbon at the time that the refilled drawer, 52, is removed It will now be evident that I hold the ribbon under slight tension, and that it .is moved forward step by step, each step being substantially equal to the length of the body of type on the type plate which occasions the movement. The de- "tails of the structure herein shown are as follows; 39, represents a cross bar which bridges the bed plate. It is elevated above the bed to allow the passage of the type plates. The ribbon roll, R is supported by a yoke or light frame, 0 pivoted on the cross bar, 39. The yoke and roll are sub- -ject to vertical adjustment by the set screw,

1". The shaft 7", of the roll, R is freely revoluble in the snap bearings, 1', provided therefor in the arms of the yoke. A spring contained in roll R tends to rotate it in the,direction of the arrow (Fig. 1.) Such rotation is normally prevented by a ratchet pawl,-o pivoted on the yoke. The ribbon when drawn from the roll tightens the contained spring. When the pawl is disengaged the spring automatically rotates the roll and retracts or rewinds the ribbon. The internal constructions of the roll is shown in Figs. 4 and 5. In order that a long ribbon may be unwound from the roll without so far tightening the spring as to cause excessive tension on the ribbon, I employ several smallsprings, which are connected in series, the strength of the group substantially equaling the strength of but one of the springs, The roll, R is a hollow drum, which contains an inner casing, 1"". The hub, r, of this casing extends through the end of the roll, R and is attached to yoke, W, by an arm, 1* (see Figs. 2 and 4.) One springm is attached to the casing, 7'. Its inner end is attached to the hub, r, of the housing, r, of the second spring, 7". The second spring has its outer end attached to said housing, 7", and its inner end fastened tothe hub, r, of the next spring housing, 1 The third spring, T, has its outer end attached to the housing, r while its inner end is attached to the shaft, T The hub of a small gear wheel, 7", is also attached to the shaft, 1*, and this gear is connected with shaft, 7", being turned by the spring, r

the roll proper, B, through a planetary gearing, shown in Figs. 4 and 5. Small and large pinions, 7' and r, are carried by a stud, i on the end of the casing, r and the larger gear pinion, r meshes with a small pinion, 9 that is fastened to the end of the roll, R forming its journal bearing on the shaft, r". The take-up roll, R is identical with R save that its spring is weaker, being just sufiicient to take'up the slack of the ribbon. The moving of the ribbon is done 'by the conveyer acting through the plate and aided by the printing rolls, and, obviously, the roll, R is not required to overcome the spring in the roll,

R The shaft, r of the take-up roll, R is held in a bracket, r extending forward from the front end of the frame. The roll shaft bearings are such that the rolls may be easily removed from the bracket r. The rolls are positioned to hold the ribbon above the path of the type plates. At the point between the printing rolls, the ribbon is held away from the upper roll byla plate, 55, which contains a largenotch or opening, 55*, so that the ribbon may rise against the envelop when elevated by a type plate. plate, 55, also serves as a guide plate'and protector for the envelop, causing it to be discharged above the plate chute in the manner depicted in Fig. 6. This plate is attached to the bar, 23, and is adjustable therewith. lt preferably extends from endto end of the upper roll and contains notches, 55, through which the dogs, 29,

operate to catch the end of the envelop, as before explained. Adjacent to the pawl, r, I arrange an upright shaft, 7*, having an arm, 1' adapted forengagement with the pawl, 1 in the frame top and another, 1', on the shelf 2. its lower end is equipped with an arm, 7", that is positioned to engage the side of the drawer, 52. A torsion spring, 1", holds it in such position. When the drawer is withdrawn, the arm, 1", is freed, and the its arm, I, strikes the pawl, r, causing it to disengage the ratchet wheel, 1, on the end of the roll shaft, 7". The heavier spring in the roll, R thereupon over-powers the lighter spring in the roll, R and rewinds the ribbo-n on the roll, R

At times it is desirable to omit one or more lines from the addresses printed on envelop-s, as in making up mailing Wrappers for towns or localities, as distinguished from persons. The type upon successive type plates are arranged in rows that are substantially constant in position beneath the ribbon, and by merely shifting the printiug roll, 6, above the ribbon, I am able to restrict the imprints as desired. This constructio-mis well shown in Figs. 1, 2, 6, 8

The

This shaft isheld in bearings, r g

and 9. For metal type a relatively hard surfaced roll, 6, is required. The rubber or other composition is placed on an arbor or sleeve, 6, having metal flanges, 6, to hold ,are provided with bosses, 26, and'the block,

6, contains a recess, 6 to fit either of the bosses. The end pressure against the block servesto hold it in engagement with the boss and the latter prevents its disengagement from the shaft, 8. By removing the block from the posit-ion shown in the drawings, the roll is allowed to shift and uncover a part of the ribbon, obviously freeing the underlying line OI'pllIlQS of type from the pressure needed to imprint them on the envelop or wrapper. tAs a precaution against loosing the block it should be placed between the spring and the; opposite roll, 26, after the printing roll is thus shifted.

The operation of the herein described inking mechanism is as follows: It will be understood'that when ,the machine is put in order the spring rolls are; initially placed under tension by the workman who assembles the machine, little, if any, of the ribbon remaining on the take-up roll, R Most of it will, at that time, be on the supply roll,'R To start the operation, the magazine, 32, is filled with type plates and the empty drawer is placed on the shelf, 2, in the under part of the machine. The inward movement of the drawer forces out the arm, 9", and allows the pawl, r, toengage the ratchet wheel, r, and lock the roll, R against rotation by its spring. A number of envelops being then placed in the holder the operator turns the crank, thereby setting the conveyer and other parts in operation. The conveyer extracts a plate from the magazine and moves it forward toward the printing rolls. On its close approach thereto, the envelop previously drawn down by the upper "roll, is released by the retraction of the dogs,

29, and meets the type plate between the rolls. From the moment of this engagement the ribbon is tightly bound between the type and the envelop, and as the latter are forced between the rolls, the ink is transferred from the ribbon to print the envelop.

During the movement of the plate and enera-bly until all of the plates from the magazine have been restored to the drawer, 52.

Upon the removal of the filleddrawer to make room for another empty drawer, the

arm,: 1", will be released; whereupon the pawl, '1", will be lifted from the'ratchet, and the roll, R being freed, will rewind the ribbon, in readiness to act with the next set of plates. The ribbon may be released at any time by hand, but the automatic action herein described is'much preferred, and my invention contemplates the use of a pawl,

cover which will prevent its operation except through the medium of the drawer.

It will be evident that the narrow ribbon herein depicted may be replaced by one which is wide enough to print an entire page, for use with type forms that are adapted to such work.

As before stated my invention is not limited to the structure herein shown and described.
