To all whom itmay concern? Be it known that I, TRI BLE DIQRQODE, a subject of the Queen of the Netherlands,

residing in the borouglrofManhattan, city and county and State of NewYork, have invented certain new'and useful Improvements in Combined Ty1)e-\/V1'iti11g.a11cl Printin g Machines; and I do herebydeclare the following-to be a full, clear; and exact description of the invention, such aswill en-- letter and insert ng the Salutations in-the" several copies individually. i The ob ect of theinventmn is tOTJIOX'IClQ, a comb ned typewritlng and printing mechanism of this character wh ch is simple-inconstruction, vrhch may be manufactured at low cost, which maybe operatedby unskilled persons and with which circular letters may be produced partly by aprinting operation and partly by a typewriting operat'on with the typewritten and paintedportions having-the same appearance and the appearance of-typewritten Work. A further ob ect of-the invention is to so construct the mechanism asto permit of insertmg not only the salutations, but also any other desired portions of the circular letters by means otthe typewriting mechanism the construction being arranged to facilitate-ops eration of the typewriting mechanism to print the desired typewritten matter atthe proper points on the sheet.

Inaccordance with the inventioma typewriting mechanism is provided with the usual roller platen movable transversely of the machine and, in add tion thereto.; a sec- 0nd platen adapted to be used in'the printa ing operation, and a support for a typeform consisting of a multiplicity of indi-- vidually set-up type is arranged in position roller, effected by the line-spacing mechanism of the machine, causes thepap'erto be forwarded over the surface of the second platen sothat a succession of OPQl'ilt'lOllS'Of the line-spacing mechanism will moye the sheet of paper into the position required for printing thereon from the form of type. Preferably, the platen for coaction with the type-form is flat and is arranged in avertical position immediately over the trontfof the roller platen of the typewriting machine. a In addition tothe two platens on the carriage of thetypewriting mechanism, rollers;-

are provided on the carriage,forsupporting;

the ends of an ink-r bbon which extends from one rollerraroundthe roller platenand then over the face ofthe fiat platen tothe other-roller; Thisink-ribbon supplies the ink for-printing :both from the key-levers .of'thetypewriter flHCl'fFOHl the type-form sothat the'bodv of the letters printed on the machine ancl the 'salutation printedby the typewriting mechanism must necessarily be identical in color. -Also, an adjustable stop isprovidcd for limiting the pressure whichthe type-form maybe caused toexertagainst the sheet'and the coactirg platen seas-tofurther fac'litate the production of letters which are identical in appearance both as tothe body ofjthe letter printed froin the type-form and the salutation'and other-parts printed with the typewriter;

In order to aid the operator in positioning the sheet with' reference-to theplaten roller 1 when printing the salutation or' any other po tion of the letter wh ch-is to lie-printed with the typewriting mechan sm; a plurality of adjustable stops is provided wh ch may be positioned so asto arrest themoveinent' of the sheet around the platen roller. When the edge of a sheet comes in contact with a stop positioned by the operator with refer ence to-the desiredarrangenient of "the" printed matter upon the sheet; the operator knows that he may then operate the t 'e-.

Also;- this. platen is mounted upon the typee writer carriage insuch a position that the movementof. the paperaround theplatenor other portion of the letter andthat there after the matter printed with the type fornr 7 will be received upon -tlie' sheet in the-:de' thereof along with the roller platen under-- sired relation to the "matter previously tvp'ewrittenthereon. In combination with these;-

steps, means are provided for moving the? edgefot av sheet-out of' eoa-ction' with, a step i aftertli'e stop-"has served its purpoiew the type-form;

Fig. 5 is a perspective view of one of the stops;

Fig. 6 is a perspective view of one of the type; and

Fig. 7 is an elevation of an impression V controlling device hereinafter described.

Referring to these drawings, a typewriting mechanlsm of the usual or any suitable construction is shown in Figs. 1 and 2, having a plurality of key-levers 7, operated by keys 8, in the usual manner.

The typewriter has a transversely movable carriage 9, adapted to move under the control of an escapement mechanism in the usual manner, it being supported upon rails 10. In the particular type of typewriting mechanism chosen for illustration, the shifting of the platen roller for printing upper and lower case letters is effected by moving the carriage 9 and all the parts mounted thereon in a vertical direction. For this purpose, one of the rails 10 is mounted upon supports 11 which may be moved upward by means of a shift-key 12. The platen roller 13 ismounted for rotation in bearings formed upon the frame of the carriage 9 and its position is such that the type of thekey-levers 7 coact with the front face of the roller 13. Two reels are shown at 14 for use in supporting a'narrow ink-ribbon which is adapted to extend between the arms of a guide 15 (Fig. 1). This ink-ribbon mechanism, however, is that which is commonly employed with a typewriting mechanism of the construction chosen for illustration, and

in adapting the machine for use in accordance withthe present invention, this'inkribbon mechanism is not employed.

The carriage 9 of the machine has a second platen mounted thereon in addition to the roller platen 13 and these two platens together with the ink-ribbon mechanism employed therewith are adapted to move together transversely of the machine under the control of the escapement. The second platen is flat and is arranged in a vertical plane extending upwardly from the front face of the roller platen 13. This flat platen is shown at 16; it consists of a sheet of hard rubber mounted upon a metallic base-plate 17. The plate 17 with the platen 16 affixed thereto is secured to the frame of the carriage 9, as shown in Fig. 4', so that it moves crosswise of the machine with the roller 13. The platen 16 forms one member of a printing couple, the other member of which consists of a form of type located directly opposite the platen 16 upon a supporting plate 18. This plate 18 has bearings 19 formed on the rear face thereof which bearings receive eccentrics 20 mounted upon shafts 21, the plate 18 being adapted to slide upon the eccentrics 2O transversely of the machine. The two shafts 21 are mounted in bearings 22 secured to framemembers 23 rising from the base on which the typewriter mechanism is mounted. At one side of the machine, the shafts 21 extend through the bearings 22 and have. cranks 24 secured thereto. The outer ends of these cranks 24 are connected by a link 25 and this link is pivotally connected to the upper end of a long lever 26. This lever 26 is connected to an operating lover of any suitable construction; in the present case, the operating lever is shown at a treadle 27 pivoted upon the floor and provided with a suitable foot-piece 28. An adjustable stop is preferably provided adapted to coact with the lever 27 so as to limit the extent of its downward movement. Such an adjustable stop is shown at 29 in Fig. 2, it being mounted upon the floor under the support for the machine.

The type of the type-form are preferably of the construction shown at 66 in F 6. For the support of these type, a plate 30 is provided having a plurality of under-cut grooves extending across the face of the plate in parallel relation as shown in Fig.

,4. The type are individually assembled upon this plate 30 by moving them lengthwise into the grooves in the plate, the lines of type being held in proper position in their grooves by any of the well known means. The plate 30 may be provided with lugs or rails 31 adapted to be received in transverse grooves in the supporting plate 18 so that the plate 30 with the form of type thereon may be readily mounted in position and withdrawn when desired.

For the purpose of guiding the platen 16 in its transverse movement, a bar 32 is preferably provided extending between the frame-members 23 immediately in the rear of the plate 17. The front and rear faces of this bar are accurately finished and brackets 33 are secured to the plate 16 and extend in rear of the bar 32. These brackets are so spaced apart as to permit of a limited extent of vertical movement of the plate 17 and the platen thereon. such movement beins effected by the shift-key 12 heretofore referred to.

The transversely movable carriage also supports the ink-ribbon mechanism. This mechanism consists of a single ribbon of substantial width which extends around the estates platen roller 13 and over the face of the flat platen 16. The ends of this ribbon are carried upon suitable rollers and one or both of these rollers is provided with mechanism for effecting the feeding of the ribbon. In Fig. i, a roller is shown at 34 mounted upon the frame of the carriage 9 to the rear of the platen roller 13. The ribbon 35 extends from this roller 34: between a pair of guides, and around the platen roller 13. These two guides, 36 and 37, are plates of thin sheet metal secured to the frame 9 of the carriage and having their forward ends curved so as to be concentric with the roller 13. Between the two plates is a narrow space through which the ribbon 35 passes and between the plate 36. and the roller 13 is a narrow space through which the sheet of paperpasses. The two

plates

36 and 37 terminate on the front side of the roller 13 immediately below the striking point of key-levers of the typewriter. The forward edge of the plate 36 is serrated and the fingers thus formed on the edge of the plate are bent inwardly as shown at 38 in Fig. 4:. These fingers press the sheet of paper against the roller 13 and thus insure feeding movement of the sheet as the platen roller 13 is turned and also hold the sheet against displacement when the type-form is operated. The ribbon 35 passes vertically upward from the roller 13 between the platen 16 and the type-form and at its upper end is wound upon a roller 39.

' This roller i journaled in brackets extend" til ing upwardly from the plate 17. On one end of the roller is a ratchet wheel4l0 (Fig. 2) engaged by a pawl 41, pivoted on a pawlcarrying arm 42. This arm is loose on one of the trunnions of the roller 39 and is moved in one direction by a spring 43 and in the opposite direction by a stop 44 secured upon the front face of the supporting plate 18. When the plate 18 is moved to carry the type-form into coaction with the platen, itsmovement causes the arm 12 to be turned against the tension of spring 43, so that pawl 41 will turn the ratchet and the roller 39 a distance equal to one tooth of the ratchet.

Each machine is provided with. a plurality of stops which may be of the construction shown in Fig. 5. Each of these stops has a part -fl5 adapted to fit into the end of a groove in the plate 30, and a trans versely disposed part 46 whose end extends into the path of movement of the sheet of paper to be printed upon. The several stops for a machine may be different as to the length of the portions 46 thereof. When a stop such as that shown in Fig. 5 is seated in the end of a groove in the plate 30, as shown'at 47 in Fig. 2, the movement of a sheet of paper effected by the line-spacing mechanism of the typewriter will carry the edge of'the sheet into-engagement with the stop. The stop will then arrest further movement of the sheet or the sheet will become bowed if the line-spacing mechanism is again actuated. In preparing the machine for use, the operator may place a stop in such position that it will be engaged by a sheet when the sheet is in position for type vriting the salutation. 01:, several stops may be arranged in position for arresting the sheet at several positions corresponding to the positions where typewritten matter is to be inserted. In order to permit of moving a sheet beyond the position in which it coacts with the stop, a strip 4:8 is provided at one edge of the plate 18. This strip is carried by arms as which are pivotally mounted upon the top and bottom of the plate 18. The'strip has a plurality of slots cut in its edge of a width slightly greater than that of the portions 46 of the stops and the fingers formed by the provision of these slots are bent inwardly as shown in Fig. 3. Secured to or formed integral with the lower arm 49 is a lever 50. By moving this lever, the several fingers of the strip 48 may be moved forward so as to engage a sheet which has been arrested by a stop and move the edge of the sheet with the fingers until. it is carried beyond the end. of the stop. The slots in the strip 48 permit the strip to pass over any stops which have been positioned in the type-channels The sheet may then be moved upward to a further extent by operation of the line-spacing mechanism.

It may occur sometimes that when a sheet has reached such position that its edge is in contact with a stop and the operator is writing with the typewriting mechanism, it will be necessary to shift the carriage vertirally for printing an upper case letter. In order that shifting of the carriage at such time may not cause bowing of the sheet due to its coaction with the stop, I provide means for efiecting the automatic actuation of the comb-plate 418 by the carriage-shift ing mechanism. For this purpose, the frame of the carriage has a lever 51 (Fig. 2) secured thereto having a cam surface 52 which normally lies under and in front of the lever 50. When the carriage is raised vertically by operation of the shift-key, this cam surface acts on the lever so as to cause it to move in the direction for actuat ting the comb-plate 4:8 in the manner above described.

The ends of the shaft of roller 13 are received in depressions in .the frame of carriage 9 shown in Fig. 2 and are held therein by strips 58 which may be moved out of the way by handles 59 thereon. When thus moved, the platen roller, the flat platen 16., the ribbon mechanism, and the parts as? sociated therewith may be raised out of coaction with the typewrltmg machine:

Theplaten roller 13 is prorvided Withthc Ill) and knob 54: simultaneously with one hand,

such simultaneous operation being desirable when the sheet of paper is in contact with a stop and it is desired toeffect a line-spacing movement of the sheet. An impression controlling device for the type-written matter is shown in Figs. 1 and 7 This consists of a spring metal piece 55 secured to the ribbon guiding device 15 and arranged to be struck by each of the key-levers 7 just as the latter is brought to the position for striking the sheet. This piece is shown in Figs. 1 and 7 as mounted on the guide 15 for the ink-ribbon of the typewriting machine. This guide is provided with a screw 56. To position the piece 55, this screw is loosened and the fingers 57 of the piece 55 are passed over it. These fingers are bent inwardly as shown in Fig. 7 so that they bear against the guide 15 and the screw 56 mav be tightened up such an amount as will hold the piece 55 in the desired position. The upper end of piece 55 presents two diverging arms and a curved edgebetween them. The upper end of each key-lever will strike this upper end of the piece 55 at a point on the key-lever near the type thereon. By adjusting the position of piece 55 with screw 56, the strength of the blows of the key-levers upon the sheet may be decreased to any desired extent. This impression controlling device aids materially in the production of printed and typewritten letters which are the same in appearance over all parts thereof, particularly, when the typewriting is done by. an operator who strikes the keys with considerable force and who. without the use of the impression controlling piece would print the typewritten matter with a heavier impression than it would be desirable to obtain when printing from the typeforms The operation of the mechanism thus constructed will now be described. The body of a letter is set up by suitably arranging type in the Channels in the plate 30. If desired, the type-form may be arranged to print the entire letter except for the salutation. or spaces mav be left at various points in which any desired words may be inserted by typewriting. This having been done,

' the plate 30 is positioned upon the supporting plate 18 by arranging it at one side of the plate 18 and then moving it laterally sothat the lugs or rails 31 enter the grooves '1 provided in the plate 18. The edge of a sheet of paper is then inserted between the rear face of the platen roller 13 and the guide-piece 36, and the roller 13 is then rotated to carry the sheet around the roller until its edge projects beyond the edge of the fingers 38. A stop such as that shown in Fig. 5 is placed in the end of a channel of the plate 30 in such position that it will be engaged by the edge of the sheet when the sheet is in the position for receiving the salutation or other matter to be written with the typewriting mechanism. The roller 13 is then turned until the edge of the sheet engages this stop whereupon the typewriting mechanism is operated in the usual manner to print the salutation. This having been done, the operator manipulates the lever 50 so as to cause the edge of the sheet to be disengaged from the stop and at the same time turns the platen roller 13. If no other matter is to be typewritten, the roller 13 is turned so as to carry the sheet upwardly between the ribbon 35 and the platen 16 until the proper position of the sheet with respect to the type-form is shown by the engagement of the edge of the sheet with another stop positioned in a higher channel of the plate 30. The sheet will still be held against acc dental displacement by the fingers 38. which. throughout the operat on above describ"d are in eng gement with the sheet. At this time or before moving the sheet upwardlv. the carriage is moved to a predetermined position with reference to the coacting scale on the frame of the typewriter so that the sheet will be in proper position for printing with reference to the typeform. The operator then presses the operat ng lever 27, thus rocki g the shafts 21 in their bearings and when the shafts are so rocked. the eccentrics thereon cause the plate 18 and the tvpe-form supported thereby to move toward the platen 16 so that the printing faces of the type in the type-form engage the sheet through the inking ribbon with the desired degree of pres ure. On release of the lever 97. a. spring 65 returns it to its normal position thus retracting the ty e-form and the operator mav then turn roller 13 until the unncr edge of the sheet is carried above the platen 16 far eno gh to permit of grasning'it and withd awing it from between the type-form and the platen. The support for the type-form a d the tynewriting mechanism are so positioned relatively that a word printed on a sheet with the tvpewriting mechanism will aline accurately with words print d from the t peform intended to be read in the same l ne with the typewritten word or words. This makes it possible to have one or more words of a line in the body of a letter typewritten while the other words in the same line are printed without the difi'erence in the method employed appearing on inspection of the letter.

It will be seen that in this way multiple copies of a letter may be printed from a menses type-form. and on each one of the copies an individual salutation may be written with the typewriting mechanism. These two printing operations are effected with the same ink-ribbon so that objectionable differences in the appearance of the completed matter such as are almost invariably present when part of the printing is done with one ribbon and the remainder with another are avoided. It will be noted also that there is no restriction as to the location of the typewritten matter with respect to the matter printed from the type-form; not only may the salutation be written in with the typewriter, but also any other part or parts of the complete letter may be typewritten. This requires merely that suitable spaces be provided when setting up the form of type and the positioning of stops to aid the operator in typewriting at the points corresponding to these spaces. a r r The provision of an adjustable stop for arresting the movement of the mechanism for printing from the type-form is important in that it limits the degree of pressure of the type-form upon the sheet; in this Way, it is possible to guard against having some of the letters printed from the type form much heavier than others as a result of which difierences in the appearance of the body and Salutation of the letters would appear, at least upon some of the copies,
