TRIMBLE DE noonn, or NEW-YORK,.1\T. Y.

COMBINED TYPE-WRITING AND PRINTING MACHINE.

Application filed September 23, 1911.

To all whom it may concern:

Be it known that I, TRIMBLE on Roonn, a citizen of the United States,-residing at New York city, county and State of New York, have invented certain new and useful Improvements in Combined Type-VVriting and Printing Machines, of which the following is a full, clear, and exact description.

My invention relates to improvements in combined typewriting and printing machines, or machines which are particularly adapted to duplicate or turn out circular letters in the copies of which minor changes occur such as in the address and in portions of the matter of the body of the letter.

A further object of my invention is to provide a machine upon which circular letters may be printed, in the main in duplicate, but in which not only the address may be changed but also the body of the letter may be changed at any point at will.

A further object is to provide a device of this character which may be mounted upon an ordinary typewriting machine after simply removing the platen thereof.

A further object is to provide means for indicating to the operator where the distinguishing matter is to be inserted.

A further object is to provide a duplicating mechanism which may be used alone or in combination with the typewriter, as de sired.

A further object is to provide a machine of this character in which the duplicating printing mechanism or duplicator and typewriting mechanism may print through the same ribbon, thus securing uniformity in the impressions.

A further object is to provide improved ribbon mechanism for a machine of this character.

A further object is to provide a construction in which the duplicating printing surface may be raised from the paper when said surface is returning to starting position, or at any other period of the printing operation desired. j

A further object is to provide aconstruction in which the duplicating surface may i be readily removed from the rest of the mechanism and a different, surface substituted without removing the entire duplicating printing mechanism from the typewriting machine.

Specification of Letters Patent.

Patented Apr. 24, 1917.

Serial No. 650,955.

A further object is to provide means for securing uniformity of impression of long or short lines of type on the duplicating mechanism.

With these and other objects in view, as will appear from the following specification, the invention consists in a construction and arrangement of parts, the preferred em bodiment of which is illustrated in the accompanying drawings, in which,

In the embodiment of my invention herein selected for illustration v 1 indicates a portion of the main frame of an ordinary front-strike typewriting machine. 2 indicates the platen carriage mounted in the usual manner upon standards 3. 4 indicates one of the type bars which is mounted in any usual and desired manner to operate upon a platen. The printing mechanism of the typewriter, however, may be of any desired construction, such as a type wheel, or otherwise. 5 is the ordinary spacing lever. The parts enumerated may be of any desired style or construction, and while applicants invention j herein shown is applied to a front-strike machine, it is to be understood that broadly it may be applied equally well to an understrike or a top-strike machine.

In applying my invention to a front-strike machine, I employ a main frame comprising end plates 6 united by cross bars 7 and 8 respectively. One of the end plates, for example, that on the right hand side of the machine, as shown in Fig. 1, has a supporting standard 9 forked at 10 (Fig. 2) to embrace the forward extension 11 of the platen carriage frame 2. This frame also has a standard 12 which is curved to rest upon the upper edge of the platen carriage frame and to extend down within the carriage frame to support and steady the printing mechanism upon said carriage frame. In this construction it will be seen that the printing mechanism is supported and carried bodily by the platen carriage frame and partakes of its endwise feeding movement. This right hand end plate 6 is also provided with a depending arm 13, and the opposite end plate 6 (Fig. 5) is provided with a downward extension 14, within which the shaft 15 of the duplicating platen 16 is journaled. As hereinbefore stated, this platen is substituted in place of the usual typewriter platen. The left hand end frame 6 is also provided with an extension 17 which rests upon the left hand end frame of the platen carriage. Each of the end frames 6 is provided with a rearward extension 18 in the extremities of which is mounted a ribbon carrying drum or roll 19, one spindle 19 on which is provided at one end with a gear 20 intermeshed with a gear 21 on a shaft 22 journaled in one of the rearward extensions 16, said shaft 22 also having a gear 23 adapted to mesh with a gear 24 on a shaft 25 journaled in lateral projections of one of the end plates 26 of the printing cylinder frame. This printing cylinder frame is pivoted upon the forward cross bar 7 of the main duplicator carrying frame. Shaft 25 has a second gear 25 meshing with a gear 27 on the shaft of the printing cylinder 27.

The printing cylinder 27 is provided with a plurality of slots 28 within which the type 29 may be removably mounted by sliding them in from the ends of the cylinder. In order to mount the printing cylinder in operative position, I provide a cylinder support consisting of segmental end members 30, Figs. 10, 11 and 12, which are fixed upon opposite ends of the cylinder shaft 31. Said members are preferably united by a webbing 30. Each of said supporting members is provided with a latch 32 adapted to engage locking slots 33 in the opposite ends of the printing cylinder. This cylinder is provided with a segmental opening 34 adapted to fit over the supporting. members 30, and to be locked thereto to move therewith. \Vithin the cylinder support are mounted the spring held bearing studs 35, upon and between which may be removablymounted a ribbon spool 36, which spool may be ke ed to the studs 35 in any desired manner. The shaft 31 of the cylinder support is eccentrically mounted in bearing bushings 37 (Fig. 6) which in turn are carried by bear ing blocks 38, slidingly mounted on guides 39 on the cylinder carrying frame 26. In order to adjust the printing cylinder to and from the platen, the bearing blocks 38 are provided with studs or pins 38 received within recessed studs 40, adjustablv threaded in plates 41 secured'to the frame 26. \Vithin the recesses of the studs 40 may be placed resilient cushions 42 against which the upper ends of the studs 38 bear to effect resilient pressure of the printing cylinder upon the platen.

The bearing bloc ks 38 are steadied within their guideways by springs 43 interposed between said blocks and frames 26. The cylinder shaft is provided with an operating crank handle 44 by which the printing cylinder may be revolved to effect the printing impression.

In Figs. 1 and 4, the printing cylinder is shown in initial position with respect to the platen, before the printing operation has been effected. In order to print, the cylinder, as viewed in Fig. 1, is rotated by the handle 44 in the direction contrary to the movements of the hands of a watch, it being understood that the cylinder is at such time properly spaced to bring the type carried thereby into printing contact with the platen.

The bearing bushings 37 are each provided with an arm 45, the right hand arm carrying a pin 46 and the left hand arm a pin 47, the pin 46 lying in the path of the crank handle 44, and the pin 47 in the path of an arm '48 secured to the printing cylinder shaft 31. By this construction, when the crank arm 44 is revolved from the position indicated in Fig. 1, it will, upon completing its revolution, strike the bushing operating pin 46, and thereby revolve its arm 45 to the rear. At the same time, the shaft arm 48 at the opposite end of the cylinder carrying shaft will strike the pin 47 and move its bushing arm 45 to the rear whereby the eccentric bushings 37 will be revolved to raise the cylinder shaft 31 and the printing; cylinder away from the platen 16.

Adjacent to the

pins

46 and 47 are provided stop springs 49 which serve to limit the swing of the arms 45 and to hold said arms in the position to which they are thrown by the crank arm n, and correspond ing operating arm 48 of the cylinder shaft. These spring arms 49, in conjunction with the pins A6 and 47, determine the extent of movement of the printing cylinder in either direction.

From the above described construction it will be seen that while the printing cylinder is being returned to initial printing position, it is held free of the platen, but is moved toward the platen by the movement of the eccentric bushings at the end of the return stroke so that upon the next printing stroke the printing operation may be again effected.

In order to secure uniformity of impression by both the type of the printing cylinder and the type bars of the typewriting machine, I provide a single ribbon 50, Figs. 1 and 4, one end of which passes around a ribbon drum 19, and through a slot 51, into said drum where it is rolled upon the shaft or spool proper 52. The ribbon 50 is rolled twice around the ribbon carrying drum 19 for the purpose hereinafter described. The ribbon spool 52 is journaled in suitable bearings in the opposite ends or heads of the ribbon drum 19 so that said spool 52may revolve independently of the rotation of said drum. As shown in Fig. 2, the ribbon spool 52 is engaged by a short shaft 53 having a crank handle 54: by which any slack may be taken up, it being understood that this shaft 53 revolves independently of the drum 19. The short shaft 53, is yieldingly held in operative position by means of a suitable spring 55, and said shaft may be moved longitudinally against the pressure of said spring whereby the shaft may be disengaged from the spool 52, and the ribbon drum thereupon removed from the machine. The ribbon 50 is led from the drum 19 between ribbon guides 56 and 57 secured to the end plates 6 of the printing mechanism supporting frame, said guides 56 and 57 passing beneath and partially around the platen 16. The forward ends of these guide plates may be arranged in any desired manner to properly guide the ribbon and paper around the platen. As here shown, the ribbon is carried between the guide plates, and, therefore, does not comein contactwith the platen in its movement around the same. As shown in Fig. 2, the outer guide plate 57 is provided, opposite the printing line, with an opening 58 to permit impact of the type bars upon the platen at any desired point. The ribbon 50 passes through this opening 58 and passes to the ribbon spool 36 mounted in the printing cylinder support, as above described. The forward extremity of the inner guide plate may be provided with a shiftable paper guide finger 59 slidably mounted upon a rod printing cylinder also-is provided a guide plate 62, between which and the guide plate 56 paper may be introduced to the platen. The guide plate 56 also may be provided with the usual pressure rolls 63 to hold the paper snugly against the platen. The guide plate 62 also forms a passage 62 with the shield 61 by which the paper is led out from the machine.

In operation, the desired subject matter of the body of the latter is set up on the type cylinder. The paper is then introduced and properly spaced to receive the salutation, which may be written in by means of the usual typewriting mechanism. In so writing, the type strikes through the ribbon 50. For the insertion of distinguishing matter in each circular letter, proper spaces are left between the type of the printing cylinder. When the printing, by means of the printing cylinder, has progressed to a point where it is necessary to insert the distinguishing matter, the latter is effected by operating the typewriting mechanism. In order to insure accurate insertion of the distinguishing matter to be printed, I provide a stop lug 29 which may be inserted in any of the type slots of the printing bed, in the type line in which matter is to be inserted, cotiperating with which is a stop 29 on rod 7, which stop is held in the path of the lug by a spring 29 so that rotation of the cylinder will be positiv-ely stopped when these parts come into engagement. Stop 29 has a handle 29 by which thestop may be released after the insertion has been made. I may also provide a guide finger 64: adjustably mounted on the rod 7 of the printing mechanism frame. When the space in the type matter. of the type cylinder comes opposite this finger, the operator is advised that the typewritten matter is to be inserted; moreover, the inserting point may be indicated by type lugs 29 of the distinguishing shape or color. From an inspection of the relative positions of the type cylinder and the platen, it will.

be seen that this typewritten matter is writa printing bed, I provide means such as backing strips 27 and 27 Figs. 14 and 15, which may be slipped into the type slots 28 beneath the type 29 to elevate somewhat the longer lines of type. These strips may be of different thicknesses to accord with the lengths of the lines. No strip is used under a short line, a thin strip is used under a line of medium length and a thicker strip for a longer line.

As the type cylinder is revolved to effect the printing operation, the ribbon is drawn around the cylinder and over the forward extension of the inner ribbon guide plate 56, said guide plate terminating just in front of the point of impact of the type of the type cylinder, hence all danger of smudging the paper by the ribbon is avoided. As the type cylinder is revolved, the ribbon drum 19 is simultaneously revolved through the train of gears and shafts 20 et seq. at a surface speed equal to that of the type cylinder. The diameter of the ribbon drum 19 is approximately one-half that of the type cylinder so that the double wind of ribbon on the spool is exhausted at the moment the type cylinder reaches approximately the end of its printing stroke.

It is desirable that the position of the ribbon relative to the platen and printing cylinder be slightly changed after each printing operation in order that subsequent operations may take place through different portions of the ribbon. For this purpose one of the spring studs 35 within the type cylinder support, which carries the ribbon spool 36 within the type cylinder, is provided with a ratchet wheel 65 engaged by a spring pawl 66 carried by an arm 67 which in turn is pivoted upon the stud 85. As before stated, the ribbon spool52 is frictionally mounted in the drum 19 and may revolve independently of the rotation of said drum. Just as the printing cylinder reaches the end of its stroke, the arm 67 comes in contact with a suitable abutment pin 68 (Fig. 2) fixed to the machine frame, whereby the ribbon spool 36 is given apartial rotation within the printing cylinder, thus taking up any slack of the ribbon ,in its path from its spool 52 to the spool 36, and drawing a slight excess of ribbon from the spool 52, it being understood that when the printing cylinder reaches approximately the end of its printing stroke, the opening 51 in the drum 19 has reached approximately the point 69 (Fig. 4) where the ribbon leaves the drum. While the printing cylinder is being returned to initial position, the ribbon drum 19 is reversed by the chain of gears above specified and the ribbon rewound thereon.

The printin cylinder is provided with a gear wheel 7 0 intermeshing with a gear wheel 71 rotatably mounted on the shaft 15 of the platen, said gear wheel 71 being provided with a spring pawl 72 engaging a ratchet wheel 73 secured to the platen shaft. By this arrangement the platen is rotated positively at the same surface speed as the printing cylinder durin the printing stroke, whereas, the eccentrlc mounting of the printing cylinder shaft heretofore described is suflicient to maintain said gear wheels disengaged while the printing cylinder is being returned to initial position. This ratchet and pawl arrangement of the platen also permits the platen to be rotated by the ordinary line spacing mechanism of the typewriting machine independently of the printing cylinder. For such independent spacing, the platen is provided with the usual spacing ratchet 74:.

If at any time during the printing operation it is desirable to omit one or more paragraphs set up on the printing cylinder, the pins 46 and 4:7 are moved by hand to raise the cylinder and its gear from engages ment with the platen gear, and the cylinder then rotated until the undesirable paragraph or paragraphs have been moved saw um past the printing point, whereupon the pins A are again moved to return the cylinder and platen gears into engagement, and the printing operation continued.

In order to mount the ribbon spool 36 within the printing cylinder and also for the purpose of facilitating inspection of the parts of the machine between the printing cylinder and the platen, the end plates 26 of the printing cylinder frame are pivoted upon the rod 7 whereby said cylinder may be moved to the position indicated in Fig. 1. Under such conditions also the gear wheel 24c is disengaged from the gear wheel 23 of the ribbon mechanism and consequently the ribbonspools may be independently rotated to take up slack of the ribbon and to properly adjust the same in the machine.

In some cases it may be desirable to use a duplicating mechanism alone. To this end I provide the end plates 6 with feet 6 upon which the duplicating mechanism alone may be set up on a table or bench.

While I have herein described a preferred embodiment of my invention, it is to be understood that the same may be altered in detail and arrangement of parts within the scope of the appended claims.
