FILLING-IN ATTACHMENT FOR PRINTING-MAOHINES.

Application filed November 15, 1911.

To all whom it may concern:

Be it known that I, ERNEST DUsoHER, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of Wisconsin, have invented a new and useful Improvement in Filling-In Attachments for Printing-Machines, of which the following is a specification.

My invention relates to improvements in printing machines and its object is to provide a type bed which may be introduced on the main type bed of the machine in connection with type forms thereon, to carry a supplementary form exchangeable and adjustable with relation to the other forms carried by the machine.

In connection with this main object my device is adapted to the insertion and removal of supplementary type forms such as are used in printing different Salutations on copied letters and in printing the addresses on envelops, and to the automatic regulation of the ribbon during the changing of the forms.

Further objects will be apparent from the following description.

My device is simple in construction and accurate in operation, .theparticular form shown being especially adapted but not necessarily confined to use in connection with a printing machine such as described in applicants companion application Serial No. 652,105, filed Sept. 30, 1911, for printing machines and improvements thereon.

In the drawings with which I have illustrated my invention and which form part of this specification, Figure 1 is a plan view of a printing machine of the class mentioned equipped with my improvement; Fig. 2 is a view on the line XX, Fig. 1 showing a side.

elevation of my improvement; Fig. 3 is a section on the line YY, Fig. 1 showing the action of the ribbon lifter; Fig. 4 is a plan view of my improvement; Fig. 5 is a side elevation of my improvement, part in section; Fig. 6 is an enlarged detail of a portion of Fig. 5 in a different position of the parts; Fig. 7 is a perspective of the supporting bracket used in connection with my improvement; Fig. 8 is a perspective of the supplementary type form used in connection with my device; Fig. 9 is a section of a detail. illustrating the supplementary type Specification of Letters Patent.

Serial No. 660,425.

form mounted in printing position on the printing block, and Fig. 10 is a detail in section showing a portion of the type form and one of its type.

In the above drawings I have shown a printing machine having a supporting frame, a type bed B carried by the frame A, on which a form C may be supported, and with which a traveling platen D cooperates in making a printing impression. My sup-' plementary type bed or printing block E is shown mounted on the type bed B and carrying a supplementary type form, type holder or name plate F which is so positioned by the printing block E as to cooperate with the platen D in the same manner as the form C on the bed B.

On the frame A are mounted sprocket wheels 2 carrying sprocket chains 3 at each side of the machine on which is mounted the platen D in the form of a roller which traverses the type form and having a Wear wheel 5 at each end through which printing pressure is imparted to the platen. The type bed B is so positioned with relation to the path of the platen D carried by the sprocket chains 3 that the platen normally travels orbitally about the type bed, and above the surface of the type in the form and out of contact with it.

Printing pressure on the platen is secured by means of pressure bars 6 at each side of the machine under pressure from the spring 7 which may be adjusted to different degrees of pressure. The under surface of the pressure bar 6 is formed with rectangular notches 8 which bear upon a portion of the periphery of the wear wheels 5 producing an intermittent pressure and repeated impacts on the platen and thereby on the form.

A tabulating rail 9 is shown at each side of the machine on which travels the wear wheel 5. The upper surface of the tabulating rail is formed with a steel ribbon 10 resiliently mounted on it by means of which local adjustments of pressure on the form may be secured.

' A color inking ribbon 1.1 is mounted on the machine between the path of the platen and the type form and is carried over suitable rollers 12 connected by gears 11 with the sprockets 2 to be operated. An operating handle 15 connected with one pair of sprockets 2' operates theplaten ,D andthe ribbon 11 in the usual manner, that is the ribbonis stepped across the bed or type form at suitable intervals while the handle is turning, the ribbon remaining stationary while each impression is being made. The specific construction for accomplishing this result is not shown, any form being adapted for use with my invention andnot constituting part thereof. Two .forms for accomplishing this result are illustrated and described in' Patent No. 1,014,094, issued to lVilliam A. Sorg on the 12th day of November, .1912, and in my application for patent, Serial No. 681,382, filed on March 1, 1912.

My supplementary type bed or printing block E consists ofa body part 16 of comparatively narrow width and extending transversely across the type bed and parallel with the line of motion of the platen D. The body 16 rests directly on the type. bed

. B on which .it is adjustable vertically by means of setscrews 17, thisadjustment being permanent when once made, to bring the printing surface 18 to such an elevation that standard type 19 in the supplementary type form F have an equal elevation with the type commonly used in the form C on the bed B. V y

The printing surface 18 as commonly used for addresses or Salutations extends less than the width of the type bed B, and at both ends of theface 18 the body 16 iscut away or depressed in elevation so that the type in the form F when resting on or above these-parts of the body 16 do not have printing contact with the ribbon 11 during the passage of the platen D. r

The sides of the body 16 are formed with grooves 20 extending the full length thereof for the engagement of the name plate F which is formed with lugs 21 adapted to travel in the grooves 20 during the longitudinal movement of the plate F along the printing block. The lugs 21 extend down the sides of the printing block and into the grooves 20 and allowthe type 19 carried by the name plate to rest upon the printing surface 18 when the name plate has reached that part of the block. Aspring 22 is fixed a on one side of the block Eby means of a The spring has contact tips 24 and 25 adapted to lie between the lugs 21 on one side of the name plate F when the name plate is in printing position on the printing surface 18. The spring tip 24 has a beveled surface adapted to permit the movement of the name plate toward the tip 25 while the .tip 25 is seated in a notch 26 in the block and presents an abrupt face preventing the return movement of the name plate when once engagedby it. As the name plate is moved along the blockE the front lug 21 of the plate engages the spring 24: and passes under it and moves on opening up the tip 25 by pressure from inside. lVhen the tip 24 engages the rear lug 21 of the plate its pressure is instantly felt by the operator as well as the release of the tip 25 which at the same instant drops behind the forward lug 21. The movement of the plate is thus stopped and for the purpose of printing it is firmly held on the block but it may be advanced by the operator and moved off the block in the same direction in which it was moved onto the block.

An extension 27 having thesame width as the block E is connected with the block by means of screws 28 and extends beyond the machine permitting a plate F to be pushed from the block and from under the color ribbon 11. The movement of the plates F along the block is accomplished by means of a pusher 29 which slides in a slot in the block on a rod 30 which is mounted on the block. A spiral compression spring 31 is mounted on the rod 30 in front of the pusher 29 and is compressed by it during the forward movement of the pusher in advancing the plate and upon the release of the pusher returns it sharply and automatically to its original position. The pusher 29 is formed flush with the depressed surface of the approach of the printing block and is adapted to be operated by hand such as by the finger or thumb of the printer. In order to secure the engagement of the end of the name plate F by the pusher a spring stop 32 is mounted The recess 33 is short and when the pusher i isadvanced to engage a plate the end of the stop 32 is forced upward to the level of the normal surface of the rod 30 thus forcing its upper extremity above the level of the pusher as illustrated in Fig. 6 where it is adapted to engage the edge of a plate F and advance it during the further movement of the pusher.

As soon as the pusher has returned to the position shown in Fig. 1 the stop 32 is retracted by the action of the spring 34 and the paper is free to travel out of the machine without obstruction.

To prevent the interference of the plates F and the ribbon 11 during their advanceting the platen to bring the ribbon into contact with the type without resistance, and is formed of smooth wire to permit the unobstructed travel of the ribbon.

The body 16 of the block E rests upon the bed B, the approach extremity of the block is in contact with the bar 37 of a supporting bracket 38 which is mounted on the type bed B being fixed adjustably to the edge of the type bed. by means of tap screws 39 and set screws e0 which are adapted to adjust the elevation of the bar 37 to any desired point. The bracket is formed with an angle shaped part 41 embracing the corner of the type bed B and the longitudinal movement of the block E is prevented by lugs 42 and L3 lying transversely on the under surface of the block which engage the upper leg of the angle part 41.

In operating my device it is positioned on the type bed at the same time that the form C is placed thereon and is fixed laterally with relation to the ends of the type bed (by spacing blocks) in the usual man ner. The ribbon is placed above it in printposition resting on the spring 35. The first name plate is then placed on the printing block E and after proper adjustment of the form C and pressure bars 6 paper is placed on the ribbon and the platen is operated in the usual manner producing a printed impression from both the form C and the plate F at the same time.

When it is desired to change the name plate F a new one is placed on the approach of the printing block and the pusher 29 is advanced moving the plate F forward on the block. The first used plate F is forced off the printing surface 18 along the block toward the extension 27 from which it may be removed by hand.

The replacing of the plates F on the block may be accomplished without interrupting the operation of the printing machine be tween the passages of the platen over the form. For convenience in positioning sheets or envelops on the type forms paper guides a5 and 16 of different lengths may be mounted on the machine said guides 15 also acting as lifters for the paper. Strippers 1-? may also be used to engage the lifted sheets and envelops and remove them from the machine. Paper slides 48 are mounted on the bar 37 to deliver printed sheets from the machine. These guides, strippers and slides will. be found fully described in my companion application above referred to.

The name plateor supplementary type form F has the form of a plate witha series of slots 50 in which are mounted suitable double shouldered type 19 adapted to engage the side of the slots for support to prevent lateral movement of the type when in printing position and to hold the type assembled when not being used in the machine. Each of two opposite sides of a ype has two shoulders 51. The type 19 are laced in the slots 50 in suitable form for printing salutations, addresses and the like and are locked in the slots by compressing the shoulders of the type at the end of the series or of a suitable blank similarly located, into engagement with the sides of the slot 50. The grooves between the shoulders 51 of the type on each of two opposite sides of the type in which the sides of the slots 50 in the name plate engage are of suflicient width to enable each type to engage the name plate freely and to rest on the raised surface of the block without being supported by the name plate during printmg.

The end portions of the plate are depressed below the level of the type bearing slots which are open at one end to receive type. The end portions of the plate described have depending lugs 21 formed integral with the plate at each corner of the plate for engagement with the grooves in the sides of the printing block as described.

The manner in which the type are fastened to the name plate so that they can move up and down between their shoulders 51 permits the type to stand in printing position, vertically independent of said plate aS illustrated in Fig. 9, with their lower ends resting on the raised portion 18 of the block and in non printing position as illustrated in Fig. 10 before and after the plate is positioned on said raised portion.

It is evident that my printing block may be used in the present or modified form in connection with any machine of the class described in which a type bed, an inking ribbon, and a traveling platen cooperate. It is also evident that for different purposes the length of the printing surface on the block may be increased with relation to the type bed and that if desired a series of printing blocks similar to that described or of any suitable construction may be used in making up a form having variable parts.

In accordance with the patent statutes I have described the principles of operation of my invention together with the apparatus which I now consider to represent thebest embodiment thereof but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
