HENRY C. OSBORN, OF CLEVELAND, OHIO, ASSIGNOR TO THE AMERICAN MULTIGRAPH COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

PRINTING-MACHINE.

Application filed January 6, 1808.

T all ZU/L/H)! it may concern Be itknown that I, llEXRY C. Osman, a citizen of the United States, residing at Cleveland. in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Printing-Hachines, of which the following is a full, clear, and exact description, reference being had to the accon'ipanying drawings.

This invention relates to a printing ma chine adapted to perform rapidl and efiiciently various classes of work.

Among the objects of the invention may be mentioned printing in imitation of typewritten work through a ribbon so arranged that both sides of the ribbon are l'n'ought in contact with the face of the type, thereby lengthening the life at the ribbon; sew ond, printing a plurality of forms successively through the same ribbon, whereby similarity of product is obtained for the first and subsequent sheets of a circular letter; third, printing at one operation of the mach ne both through an inked ribbon with individual type and directly from an inked form, whereby a letter head and the imitation typewritten body oi the letter may be produced at the same operation; fourth, printing in a plurality of colors on the same sheet; fifth, printing the signature in imitation of handwriting on a letter; sixth. cn (lowing the machine with a capacity for us ng a continuous roll of pape' automaticallv severed into sheets: and finally, providing va ions features contributing to the adaptability and elticiency oi the machine.

The invention consists of the means or mechanism. broadly considered. by which the above described results or any of them are obtained. as well as the more particular embodiment of the invention herein illustrated. and hereinafter more fully described.

(3 is a rear elevation of the machine; Fig. 7 is a detail in elevation showing the mechanism for controlling the signature roller; Fig. 8 is an edge view of ii clutch controlling the signature roller; Figs. views of this clutch in disengaged and engaged position respectively; 1* ig. 11, is a perspective of type which may be employed in the embodiment shown.

As shown in the drawings, the frame of the machine comprises the base portion 15, upright end plates 16 and 17 and cross stiffening webs, as for example, 18 and 19. Be tween the frame uprights 16 and 17 is mounted the printing drum 20, on .the shaft 24, and two impression platens 21 and 22. This drum is rotated by any suitable means. a crank 529 on the shaft being shown in the drawings, which is to be taken as illustrative of any power or hand driving mechanism. The printing drum has end members 23 mounted on the main shaft 9% and these end members carry between them partially cylindrical members 25 and 26 whose outer surfaces carry rails :27 providing means for holding rows of individual type, grooved on theirsides as shown in Fig. 11) to receive overhanging edges of the rails. The members 25 and J are preferably formed of hollow webbed structures, as shown in F i g. 2, for lightness and strength. The surface of each is preferably of sufficient size to carry a page form of assembled type. This drum is provided with spools to carry the ends of the ribbon. There may be two of these spools, one for each end of the ribbon. or there mav be more spools, whereby a plurality of ribbons may be used. The drawings show four spools adapted to hold two ribbons. but so arranged that a single ribbon may be held across the entire printing surface without changing the spools. These spools are mounted in the space with in the drum between the menibers F25 and 526. and are designated 31, 32, 33, and 3% respectivelv. T 1e single ribbon shown. designated 30, has one end carried by one of its spools. as 31 for example, and thence passes around one of the type holding segments as 26. thence through the drum between the segmental members and against the barrels of the spools 33 and 34, emerging at a sub- 9 and 10 are face stantially diametrically opposite point and passing across the segment 9.5, the end being carried by the spool In the above described arrangement it will be seen that the type on the segment 26 engage on one side of the ribbon while the explained,

folded 'togeter.

type on the segment engage the opposite side of same ribbon. The ribbon is antomatically fed, as hereinafter described, so that the portion engaged on one side at one point at some succeeding impression comes to be engaged on the opposite side on the nt, the result being that the entire ribbon is used. it is well known that the ink given up by a ribbon is largely from its surface and that much more e 'ectire results can be had by printing from both sides of the ribbon. However, the ibbon dries in use and thus loses its eiiiciency, so that ii one side is first exhausted and the ribbon then turned the other side will not give the expected amount of ink. Furthermore, the change from an exhausted side to a comparatively fresh side intr0 duces a variation in the appearance of the product, which is disadvantageous in attempting to the body of the letter szith a typewritten address. There is also some b r ordinarily in changing the face of the con, so that the operator as in ect the change, For sons it is very desirable to print 3/ and alternately with the two faces of the ribbon, is accompiishedin the present machine.

i has been heretofore stated that each i members 25 and 26 has'preferabiy a of sufiicient size to carry a page type. This enables the first and sheet oi letter to be carried on the o AASYi'ilJB'ES mentioned and both printed at c same rotation of "the drum. The two be ts thus printed not only through the ame ribbon, through adjoining portions the ribbon, while such portions are state of wear. The two sheets, re, perfectly match. These two saeets led out of the machine one on top oi the other, as hereinafter more fully position to be conveniently clined l'l'fhen a single ribbon is used, taking the course above described, the two spools UU idle, the ribb simply resting th spool barrels it does against aller provision in extra enables two independent r d when-"er desired, e i" to spool 32. ement is that be used, operation prints bcrs may carry sheets alternatively in two colors. This is of great value where it is desired to print two colors on a sheet, for by the mechanism just described, a sheet may be printed in one color by one segment, and the same sheet printed in another color by the next segment.

It is to be understood that when both faces of a single ribbon are used, only one platen is in action, while when two ribbons are used, both platens are brought into operation, the paper being suitably deflected between the platens so that each printing surface may print on each platen on portions of the paper which are to form separate sheets. This will be more fully explained The platens 21 and 22 are mounted between the frame members below the printing drum by means of shafts to which have eccentric bearings in the frame members 16 and 17 or in bushings carried thereby. Suitable levers 41 and i2 furnish means for adjusting these platens by rocking the shafts. A ring 4:3 is carried by theouter side of the frame around the platen shaft and is held in adjusted position by a clamp.- ing set screw it. A suitable leaf spring 45 projecting from this ring 'i urnishes means for'holding the lever ll or e2. This construction is shown in Patent $51,004,408, granted September 26, 1911, to Barometer and claimed therein. I By its means the platen may be adjusted accurately to desired position and then may be thrown out of position whenever desired and returned at one stroke to the same active position, When but one of the platens is used, the other is thrown by its lever to idle position, and acts simply as a guide roller.

The space between the segments25 and 26 allows for the letter head and, as each of these segments may carry a page form, each rotation of the drum may print properlyletter head. This is accomplished by means v additional segmental members 47 rried by the end members of the ween the adjacent edges of the 25 and 26. These memirotypes to print the letter head, or in W of such formalletter head, a heading ot individual type may be used, the latter being more suitable for second sheets. The member 47 is shown with a smooth surface and an elect-rety e may be clamped thereto at its edges, when? the memdrum segmental membe s Harry G.

of this nurses her 48 is illustrated with rails suitable for holding either individual type or an electrotype clamped on the face of the rails. Either means may be used, as desired.

To allow access to the interior of the drum for removing the ribbon spools, I make the segmental members 47 and 48 removable. This may be accomplished by allowing these members to extend across the end members 23 of the drum, as shown in Fig. 5, where the segmental members is socured by a screw 49.

To ink the portions of the drum which carry the letter-head, I provide an inking roller 50 which'may be of felt or similar material, and is so supported that it is out of action when the ribbon is passing beheath it but comes into action to ink the direct-printing surface. This movement of the printing roller is accomplished as shown by mounting it in a pair of arms 51 pivoted to the end plates 16 and 17, the arms being drawn toward the drum by suitable springs 53, and cams 54 being provided to hold these arms with the roller normally out of engagement, but allowing it to pass into engagement at the proper time.

Whether the machine )rints its own letter head or not, it is desirable to print from a continuous roll of paper, thereby saving trimming and also doing away with the mechanism for feeding individual sheets, which frequently introduces an element of delay in the operation. In the form shown, the paper, indicated by 55, is mounted in a continuous roll 56 on a suitable core 57, havinggudgeons 58 resting in recesses in the frame members 16 and 17. From the roll, the paper passes across the platen 22, thence downwardly beneath the take-up roller 59, thence upward across the platen 21., thence outward between feed rollers (31 and (32 and finall between the two members and 66 of a (IllfQ adapted to sever the sheets. The take-up roller is adjustably mounted by having its shaft 67 pass through slots (38 in the frame members, nuts on shaft holding it in selected position. This is to give proper registration on the sec nd presentatiomof the :paper to the printing member, where there is such second presentation. This second presentation of the printed sheet normally occurs where there are two dissimilar ribbons on the drum. With a. single ribbonone platen or the other is normally idle. The detour of the paper, caused by the takeup roll, from the impression line of one platen to the impression line of the other. is substantially equal (in the embodiment shown) to half the periphery of the drum plus the distance on the periphery of the drum between the impression lines of thetwo platens.

The feed rollers 61 and 62 preferably consist of several sections on shafts 63 and 64.

These shafts are geared together and are connected by an idler 70 with the gear 69 on the drum, this latter gear also meshing with the two gears 71 and 72 on the two platens. The gear 61 also meshes with a gear 73 which carries a depression cam 74 giving for each rotation of the gear 73 one reciprocation to the lever-'75 which operates the knife 63. The gear 73 is of half the pitch diameter of the gear 69, wherefore it results that the knife 65 is operated once for each half rotation of the drum. The knife is so positioned with reference to the platens as to sever the sheet at the proper point. A suitable table 78 supports the paper between the feed rollersand the knife, and the guiding bowed cover 79 insures the sheet passing between the-knives, but allows it to buckle upwardly when its progress is stopped by the knives being in engagement.

In order to automatically print the signature in imitation of handwriting, I pro vide the following mechanism: On the shaft 64.- of the feed roller 62, and between the spool members constituting that roller, I mount loosely a sleeve 81, carrying on its surface a rubber arc-shaped form of the autograph signature which cooperates with a roller platen 82' on the shaft (33 between the rolls 61. The roller 81 is connected with one disk 84 of a clutch. Adjacent to this disk is another disk 85 and between them are rollers 86. These rollers occupy somewhat closely but freely openings in the disk 85 and occupy larger :ln'1-like openings in the disk 84. A coil spring 87 tends to torque these members so as to cause the rollers to grip the shaft 64. Such torque, however, is normally prevented by the nose 88 of a pivoted lever 89 which engages a shoulder on both disks. This leyer carries a roller 90 adjacent to the periphery of the printing drum near one end. To actuate the siguaturc roller at the proper time, I provide a suitable movable lug 92 which has an inner T head whereby it may he carried at any point on the drum. \Vhen this lug lllov s beneath the roller the nose 88 is withdrawn fr m the shoulder on the clutch menu hers. Thcreupon the spring 87 turns forward the clutch member 85 to shift the rollers into the gripping portions of the slots 80 and thus cause them to bind on the shaft (34; whereupon the signature roller revolves with the feed roller and the signature is printed, the ink for this purpose being supplied by a suitable felt roller 95, which is in position to engage the signature form. As the signature roller is completing its rotation the shoulder on the clutch disk 85 engaging the nose 88 releases the clutch and holds the roller in position.

I will now take up the description of the ribbon feed mechanism, which is arranged to automatically reverse itself when either ribbon spool becomes empty. This feeding mechanism is broadly covered in Patents #997,285, 997,286, 997,287 and 997,615, granted July 11, 1911 to H. C. Gammeter, but the mechanism for adapting such ribbon feed to the machine of the type herein shown is my invention.

The ribbon spools are removably held to suitable driving mechanism, which is best shown in Figs. 1 and 5. This driving mechanism acts on spools 31 and lhe driving mechanism, however, is provided at the spools with gears 101 which mesh with gears 102 connected with the spools 33 and 31, so that these latter spools are also rotated. Accordingly, the operation of the driving mechanism is the same whether a single ribbon is used, passing from spool 31 to spool 32 in the manner shown in Fig. 2, or whether two ribbons are used passing from spool 31 to spool 33 and from spool 32 to spool 34.

The ribbon feeding mechanism is pro vided with two pawls 10% and 124 which are adapted to operate ratchets 103 and 123 respectively, these ratchets being shown as connected with the spools 31 and 32 by suitable means which allow the removal of thespools. These pawls are pivoted at 105 and 125 to plates 106 and 126 respectively, which in turn are pivoted at 107 and 127 to a bar 108. This bar yokes around the boss 109 of the end member 23 of the dam ad lies adjacent to the face of the eccentric 111 stationarily carried by the end member 16. An eccentric strap 1'12 surrounds this eccentric and is connected by a pin 113 with the bar 108. This bar is guided by yoking around the boss 109 and also by the lug 114 on the bar sliding on a pin 115 and carried by the drum flange 28. A spring 130 connects the lower end of either of these pawls 104 and 121 with a suitable pin on the plate 106 or 126, so as to give the nose of the pawl an outward tendency toward the ratchet.

In accordance with the above, when the drum is rotated the bar 108 is reciprocated, and one of the pawls, 104, for example, en-

gages the corresponding ratchet to 'rotate it, the other pawl, as 121, clearing its ratchet. The pawls, in this case, are held in their respective active and idle positions by a detent roller 135 engaging a notch 136 in the end of the plate 106, this plate holdi ig the plate 126 by reason of the connecting yoke 128 pivoted to each of them, When, however, the spool from which the ribbon is fed, as for example the spool 32 in Fig. 4, becomes empty, the tautness of the ribbon causes a retardation of the ratchet 103, which causes the plate 106 to swing over to its other position where the detent roller 135 engages the notch 129. This movement, by reason of theyoke 128, shifts the plate 126 on its pivot so that the pawl 12% comes into the path of the ratchet 123. This shifting takes place before the pawl 101 releases the ratchet 103 and is allowed by reason of the give in the spring 132 connected with the arm 133 which has a lug 131 engaging the outer side of the pawl. As soon, however, as the pawl 104; releases its hold on the ratchet, this spring 132 draws the pawl intoidle position and thereafter only the pawl 124 operates a ratchet. Reference may be had to the Gammeter Patent #997,28Tyeferred to, for a fuller description of this shifting operation to reverse the ribbon. I

The above ribbon feed mechanism is the same whether one ribbon is employed, as

shown in Fig. 2, or whether there are two independent ribbons. In the latter case the gearing connecting the spoolscauses the rotation of one ratchet to rotate not only its spool but the adjacent spool.
