Application filed October a, 1910. Serial No. 586,057.

To all whom it may concern:

wholly written or Be it known that I, DAVYDD C. Hn'onns,

a citizen of the United States, and resident of Chicago, Cook county, Illinois, have invented a certain new, useful, and Improved Dating-Machine, of which the following is a full, true, clear, and exact description,

such as'will enable others slnlled in the art to which it appertains to make and use the same.

My invention relates to improvements 1n so-called printing and addressing machines, and has special reference to improvements whereby the letters, statements, circulars and the like printed by the machine will be dated at the time that they are printed.

The object of my invention 1s to so 1mproie the construction and equipment of machines for addressing, and printing letters, statements, circulars, and the like that the same may be dated simultaneously with their production, and in a manner that will give them the appearance of having been produced by a typewriter machine.

Another object of my invention is to provide a dating mechanism or device upon or in connectionwith an addressing machine, and which shall be readily adjustable with relation to the other parts of the machine, to the end that the position of the date upon the printed sheet may be varied to suit the requirements of the body of printed matter.

A further object of my invention is to provide a date printing attachment of rotary character which shall be self-contained and capable of being attached to or removed,

- pressed upon the paper, and in this connection itmay be stated that my further purpose is to provide'an improved addressing and dating machine .using a plurality of so-called address plates, and in which the printing operation shall be performed with a minimum quantity and expenditure of ink fabric.

Still further objects of myi'invention will appear hereinafter.

My invention consists generally in an ad dressing machine utilizing a plurality of address plates, and including a dating device: for printing a date upon each article ,which is addressed.

My invention also consists in a letter printing, addressing and dating machine adapted to perform at each operation all three of the functions mentioned.

These and other features of my invention will be more readily understood by reference to the accompanying drawings in which I have illustrated a preferred form of my invention.

These drawings constitute a part of this specification, in which drawings Figure 1 is a top plan view of the forward portion of a printing machine various parts of which are broken away to expose the dating mechanism to view; Fig. 2 is a transverse vertical section on line 22 of Fig. 1; Fig. 3 is a vertical longitudinal sectional view taken on line 3-3 of Fig. 1;

Figs. 4 and 5 are sectional views of the dating mechanism taken substantially on line w-mof Fig. 2, these views showing the type in and out of the printing plane re spectively; Fig. 6 is a view of that portion of the dating mechanism included between the parallel dotted lines in Fig. 5 looking in the direction of the arrows; Fig. 7 is a top view of'the type holder; Fig. 8 is a fragmentary view of the carrier showing the type holder in side elevation; Fig. 9 is a sectional view taken on line 99 of Fig. 8.

My invention relates especially, but not necessarily, to that class of printing machines of the character employed for addressing letters, envelops, cards and the like,

for duplicating letters and circulars; more particularly in imitation of ordinary typewritten matter. It is desirable that these machines be arranged to date the letters, cir- Patented Sept. 7,1915.

I in connection with printing machines of this character which meets all of these requirements in a single and satisfactory manner. -The machine with which I have chosen to illustrate my invention is of the Rogers type where successive pieces of printable material are fed to a rotary printing mechanism by which they are printed and discharged. The following explanation of the nature and functions of my invention will clearly point out that the invention is. not necessarily limited to the particular machine illustrated in the drawings and that, by suitable modification, it may be madcapplicable to various other printing machines or mechanisms without departing from the spirit of the invention.

The machine illustrated in the drawings is known as a multi-printing and addressing machine. It is of the class wherein the date,

superscripti'on or address, Salutation and body of the letter are printed in a single operation as the successive sheets of paper are fed to the printing mechanism.

The machine has a rotary printing mechanism comprising two large drums 1 and 2 co-axiall mounted upon a shaft 3 and, in the pre erred construction, independently rotatable together with a platen orpressure v.roll 40f a length substantially equal to the combined length of the two drums, This roll co-acts with the drums to print the pieces of paper, cards, or envelops 5" which are successively fed at timed intervals from the feed mechanism 5.

In the particular machine illustrated it is desirable to reduce the size of the parts as much as possible, and to this end I provide a comparatively small type plate drum 1 and letter drum 2. With a small type plate drum, however, it is not advisable to print at each revolution of the drum, since the wear and tear on the machine and plates would be too great; therefore, I prefer to so proportion the parts of the machine that an address plate will be brought forward to the printing mechanism at each second revolution of the plate drum. Thus it isevident thatfor each printing operation the plate drum must make two revolutions while the letter drum is making one. I prefer to rotate the plate drum at a constant speed and to vary the speed of the letter drum 'to suit the conditions just described. For this reason I connect the plate drum directly to the surface of the letter drum. At the same time, While the type plate drum is smaller in diameter, the peripheral speed of the type speed of the letterdrum. It will be underplate on the same must be the same as the peripheral speed of the type drum in order that the type plate will move at the same surface speed as the surface speed of the letter drum.

The printing mechanism is rotatably mounted in the side members '6 of a suitable supporting framework which maintains the various parts in' coiiperative relation to each other. one end of the shaft and serves as a means of operating the machine. The large drum 2 is provided with a plurality of type" grooves on its periphery in which grooves the type 8 are set up to represent the body of a letter or circular. This drum is referred to as the letter or body drum. The drum 1 is known as the type plate drum. It co-acts with the pressure roll to press the type plates and pieces of paper into printing engagement 'as they pass through the space between said drum and roll. The type plates 9 are individual in character each usually representing a name and address. They are brought forward at intervals along the guide'or bed plate 10 by a conveyer chain 11 leading from the magazine (not shown) at the rear of the machine in which they are initially stacked. The forward end of the conveyer chain is co-axial with the drum 1 and is carried upon a sprocket wheel 13.

The type plates are moved through the space between, and are pressed by, the roll and drum, being thence discharged "into a chute 14 by which they are directed into a receiver (not shown) in the lower part of the machine. Figs. 2 and 3 show a type plate which has passed the printing mechanism and is on the way downwardly to the receiver.

The ink is supplied to the type or the type plates and to the type on the letter drum 2 by means of a wide inked fabric or ribbon 15 extending through the space between the A crank or handle 7 is secured to letter drum and the platen roll. This ribbon, as shown in Figs; 1, 2 and3 .is held above the type in a tensioned condition by suitable holders15and 15", these holders acting to intermittently feed the ribbon through the printing mechanism in'time for the printing operations. The ribbon, as clearly seen, is sufliciently wide to overlap part of the type plate drum so as to supply ink to the type upon the type plates. As the articles to be printed are successively fed downwardly along the guide plate 5 they pass above the ribbon through the space in the printing mechanism, and since the type are below the ribbon they print through the ribbon and as a result the imprints resemble that done by the ordinary typewriter.

' For the purpose of accommodating the dating mechanism the major portion of the type plate drum is grooved or made smallerv in diameter, as more clearly shown in Fig. 2, so that the dating mechanism lies principally within the periphery of the drum and hence within the printing plane or level. This portion of the drum is made wide enough to allow considerable adjustment of the dating mechanism in an axial direction so that the date may be positioned at different heights on the letter. The dating mechanism, as shown, may be placed on either side of the conveyer chain sprocket wheel 13.

I prefer to make the dating mechanism in the nature of a self-contained structure attachable or detachable as a whole, but it is clearly obvious that it may be constructed as a part of the printing mechanism if desired. It is rotary in character and preferably associated with the type plate drum of the printing mechanism. For this reason I provide an arc-shaped carrier or frame 16 extending substantially half around the smaller periphery 1' of the drum and conformed on its inner and outer edges to the curvature thereof. By constructing the carrier in this manner it is adjustable circumferentially of the drum and independently thereof so as to position the type holder 17, which it carries, relatively to the body and superscription of a letter, statement or the like; thus making it possible to place the date in various positions on the edges of the sheet of paper. The articles to be printed are preferably fed so that the printing begins with the left hand margin and the address or superscription and also the salutation begin at this point. Since the date is usually close to the right-hand margin of the article it follows that it will be printed toward the end of the printing operation. The reason then is obvious for arranging the dating mechanism so that it is adjustable because the printing of thedate may be ad- 'justed to lag the proper amount behind the beginning of the printing operation of the article.

The frame or carrier has an extension 19 on one of its ends which serves as a means for clamping the frame in its adjusted position on the drum. Like the frame, it is conformed to the periphery of the drum, so that the frame and extension together embrace the drum for more than half of its periphery. This extension is pivoted at 21 to the frame,as clearly shown in Figs. 4 and 5, for the purpose of permitting the removal of the dating device. It is operated by means of the screw 22 carried in the tail 23 and acting against the end of the frame. This arrangement enables the dating mechanism to be conveniently removed from the drum'or clamped in position thereon by simply turning the screw in the proper direction to ti hten orloosen the clam The parts 0% the machine depicted in the drawings are so proportioned that as before mentioned a type plate is brought forward at every second revolution of the type late drum. The particular embodiment of my invention herein described is therefore constructed to adapt it to this condition. The. type holder or type block 17 as will be seen, is peculiarly shaped. It is curved at its upper and lower ends, the arcs of curvature being concentric to the circumference of the drum. This holder is radially movable so as to carry the type 24 into or out of the. printing plane, as shown in Figs. 5 and 4,

respectively, the holder being guided in its movement by the sides of the carrier or frame 16. Two spiral springs 25 are anchored respectively to the bottom of the frame and to opposite edges of the type holder and constantly tend to maintain the holder in its lower or non-printing position. For the pur ose of shifting or moving the type holder 0 the dater into and out of the printing plane I provide a cam 26 which co-acts with a small roller 27 on the type holder. This cam is formed, as shown, to alternately raise the type holder in to prlnting position and withdraw it therefrom, so that the type holder is raised into printing position during the revolution of the drum in which a type plate is passing through the printing mechanism, and is in its depressed or withdrawn position out of the printing plane, during the revolution of the drum wherein no type plate is passing through the printing mechanism. In other words, the type holder is in its rinting position every second revolution of the drum. The cam is mounted upon a small shaft 28 journaled in the sides of the frame and this shaft carries a small toothed wheel which is actuated through the medium of a long pawl 30 by the bell crank lever 31 pivoted at 32 to the side portions of the carriage. A small spring 33 constantly holds the pawl in engagement with the toothed wheel. The spring also holds the longer arm of the bell lot site sides of the type holder,

crank lever 31 in its operative position, that is, m a position wherein it projects beyond the surface or periphery of the drum. During the rotation of the drum this arm strikes the up er platen roll and actuates the pawl to shii the cam around one point or step at a time thereby alternately shifting the type holder into and out of printing posit1on. This 0 eration occurs in advance of the arrival o the type holder at the printposition, as is evident by the direction of rotation of the drum.'

One of the objects of my invention is to produce printed articlesin imitation of the ordinary typewritten letters and to make the printed date consistent in this respect with the rest of the printed article, I rint the date through an inked fabric or ri bon. Under certain conditions I could obviously widen the main ribbon 15 sufliciently to lap the dating type. But it frequently is the case that the date and address only are printed and not the body of the article, hence it would be quite expensive and uneconomical to use the main ribbon. Furthermore, in this particular machine the ribbon 15 has a reciprocating progressive movement and it might not be moving in the proper direction at the instant the date is being rinted. I therefore provide a separate and independent inker for the dating mechanism. This consists of a small inked fabric or ribbon 35 through which the type print. This ribbon extends along the face of the type (as shown in Figs. 4 and 5) and is stretched between and wound upon two reels or spools 36 and 37 disposed on oppothe reels being removably journaled in the sides of the frame. In order that the ribbon may present a-relatively new inked surface for each impression of the type, I rotate IOIIG of the reels so that theribbon is pulled forward or moved a slight amount with each revolution of the drum. One of the flanges of the reel 36 is toothed to form a gear and this meshes with a small pinion 37 of a reducing train of intermeshing gears. The gears of this train are suitably journaled in the sides of the frame. The other end of this train of gears has a toothed wheel or ratchet wheel 38 which is actuated by means of a small spring pressed pawl 39 carried upon the longer arm of the bell crank lever 31 so that each time the bell crank lever strikes the roll it steps the toothed wheel around one tooth and, through the medium of the train of gears just mentioned, rotates the vreel 36 and winds the ribbon on said reel a proportionate amount. The reason I have provided the speed reducing train of gears is that the rate at which the ribbon moves is just sufiicient to enable all of its inked surface to be completely used and it is practically worn out. This eliminates the necessity of shifting the ribbon back and forth and hence provides a much simpler structure. A drag or brake spring40 acts on the edges of the reel 37 for the purpose of constantly maintaining the ribbon under tension and keeping it properly stretched in position. The ribbon is guided onto the type by means of a small guide 41.

The type 24, which are preferably used with this mechanism, are metallic and have grooves 43 in their side edges as shown in Fig. 9. They are set in a type channel 44 mally maintains this opening in the channel wall closed, but, as shown, it may be sprung away sufliciently to permit the entrance or removal of the type.

It is sometimes desirable that a printed impression be made for each revolution of the drum. For this purpose I provide holes 49 in the type holder and also in the sides of the frame. These holes register when the type holder is in its raised or printing position, and by inserting pins therein the type holder may be held in said position.

It is also desirable at times to dispense with the use of the dating mechanism without removing it from the drum. For this purpose I provide holes 50 and 51 in the bell crank lever 31 and the' sides of the frame, these holes being adapted to register when the lever is in its depressed or non-.

operative position. By placing a pin in the holes when they are registered with each other the entire mechanism may be placed in an inactive condition, the effect. being the same as if the dating mechanism were removed.

It is to be noted that my invention in a sense constitutes an auxiliary printing mechanism co-acting with the main printing mechanism of the machine, and if desired may be permanently related to said main printing mechanism.

While I have shown one embodiment of my invention for the purpose of an understanding thereof, I do not desire it to be limited to the particular structure since it is obvious to those skilled in the art that my invention is capable of various modifications without departing from the spirit thereof.
