[o all whom t may concern.'

Be it known that I, HERMAN Gr. LinnEN- THAI., a subject of the Emperor of Germany, having declared my intention of becoming a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented cert-ain Improvements in Printing Mechanism, of which the following is a specifica tion.

My invention relates to printing machines, and consists primarily of mechanism which is particularly serviceable when used as an` auxiliary attachment for machines of the type known as offieeor duplicating" machines for printing letters, circulars, etc.. which have the appearance of having been separately Written on a typewriting machine. Vhen used for this latter purpose, my invention is especially adapted for printing electrot-ypes of signatures, signing clauses, letter heads, etc.

In the above mentioned types of office machines, bthe body of the letter or circular to be printed is set up by selecting and. sliding individual type-letters from a niagazine into grooves of a plate or rotatable cylinder and printed through the medium of an As it is desirable to have the signing clause or signature inade by an electrotype and printed in a different color ink from the body of the letter, such signatures aiid signing clauses were heretofore made by a separate. operation. In other printed, the type constituting the body of the letter had to be removed from the rotatable cylinder and replaced in the magazine; then an electrot-ype of the signature was inserted-in the rotatable cylinder, after which a different. color ink-ribboii was brought into operation and the letter again passed through the machine to receive the impression of the electrotylie. This not only required a loss olfdtime-in inserting the electrotype and passing the letters. cir., thro-ugh the machine twice, but oflcn caused the same to become marred and unerenly printed.

The chief object'of my invention is to construct' printing mechanism of the above type that. will make itpossible to print` in one operation.y letters having a signature or other matter produced in a color which is different from that ofthe body of the letter. Another object is that the construction of my invention will be durable, easy to adjust and which may be easily attached-to and cooperate with another printingmachine when it is .so desired. l

These and other objects and advantages@- I attain in the following manner, reference being had to the accompanying drawings, in which: v

Referring to the drawings.tlie main frame l of a rotary printing machine forms a rotary support for a shaft 2 liaving a typedrum 3 and a handle 4 fixed thereto. A platen roll 5 is rotatably mounted on the frame 1 adjacent the type drum S. and it is between the latter and the platen roll 5 that the blank sheets of paper are inserted. 'The foregoing elements may be of any known type and do not form a part of my invention.

Side brackets or frames and 7 are secured to the main frame 1 and form the support for two rot-ary shafts 8 and t) and a shaft loehaving eccentric trunnions 10. Intel-meshing gear wheels 11 and 12 are keyed to the shafts 8.and t), respectively. 12 is loosely mounted .on a lsleeve 6a; the latter forming a bushing for and concentric with one of the trunnions 10". The other of the ti'unnions 10. extends into an ecrentli'r recess in a VIArviutff. .\n elliptical 11( gear slotv13a is formed in the gear 13 and forms .a' driving means more fully referred to here v and 18 fixed thereto. A gear 19, intermeshingwi'th gear 16, is rotatably mounted on a 21. Another gear 23, made integral `with the gear 19 in the present instance, Vis also journaled on the stud-shaft 21.' Two st-ud shafts 24 and 25 extending from the bracketI 6 form a bearing fortwo gearsA 26 and 27; the' gea-r 26 being in mesh with the gears '12 and 13; and the gear 27 being in mesh with the gears 13 A ina-in driving gear wheel 28 in the present instance is fixed on the shaft. 2 and meshes with the gear-23. A f Y v `The sleeve 15 forms a guide for a lever 29 by passing through a slot 30 inthe said lever@ l In like manner, a rod 31 attached to the bracket 6, acts as a guide for the lever 29 by passing through a. slot 32 therein, (Fig. 9). A shaft having eccentricl trunnions 34 is journaled in the brackets 6 and 7.'

.A pendentor carriage 351is journaled on the shaft 33 and is grooved at 36 for the reception of type or electrotype 37. An anti-friction wheel 38 is journaled on a pin 39 extending from the carriage 35 and 'adapted to be engaged by the cam 17A to rock or' swing the said carriage in a manner more fnllyreferred to hereinafter. l A chain 40 has one end Yattached to a ltrunnion 34 and the other end attached to an arm 41 extending -fron the lever 29. The chain 40 is always kept taut by the action of a. torsion spring 42 which has one end attached and has the other en d frolled onthe spool 47, as clearly shown o'p Figs-3 a A.d 6.

A double-arm liever? 4 9 is pivo ed on the carriage 35 at a tension spring 51 has one end connectef to the frame 6 andi the otherend to one lijm of the lever 49% In like manner, a tension springt, 52 is at-i tached to the other anni of thef lever 49g and to the carriage The .sa d spring'` 51 is stronger than the spring 52 s` that the the `spring 52. A double pawl 55 is oted Von the shank of a screw 56; the said screw having its inner end engaging a tapped bore of av sleeve 57 adapted to av slot 58 in an extension 59'of -the carriage 35.

A shifting lever 60 is provided with a slot 61 througlrwhichpasses the shank of the' screw 56, and a tension spring 62 is centrally connected to the pawl 55 and to the shifting lever 60. A second sleeve 63 is also movable within the slot 58 and a pin 64 passes through the sleeve 63 and is screwed into a locking plate G5. A portion of t-he screw 56 alsopasses-through a bore in the' plate 65 so that the said late 65 cannot -possibly have arocking motion with respec't to the carriage A35, but can slide in a direc-v tion as prescribed by the slot 58. The plate Y A 65 isprovided with a pin 66 which coperates with V-shaped lslot 67' formed in-l gageinent with its. respective ratchet wheel 53 -or 54. A pin 69 passes through the lever 49 and a plate70, and is screwed into the sleeve 57, (Fig. 7). The-pin 64 valso passes through the plate 70 sothatthe latter acts as4 .a slide operable against the outside surface of the extension 59. v

A rubber coated 'roller .71 is loosely mounted on the shaft 10, and has a pin 71 projecting frombne end and engaging Tthe slot 13 in the gear wheel. A13. A hand Wheel 73 is keyed on the trunnion 10a adjacent the sleeve. 72, and pin 74, threaded at .the free end, projects from the frame 6 and extends through the slot 72. A lever 75 is mounted on the threaded portion of thepin 74, and when turned,'tends lto lock or unlock the hand Wheel. A tension spring 76 has oneend attached to a pin 77 extending from the frame 7 and the other-end attached to a pin 78 carried by the carriage 35;- the function of the spring 76 bein to move the carriage 35 in the direction o the arrow, Fig. 5, to print. The shaft 8 is'adjust-ably mounted in eccentric bearings 79 in the frames 6 and 7, and is provided with wheels 80'and 81 which contact with wheels 82 and 83 on the shaft 9 and form a conveying means for the Qother end attached to a pivotedv latch leveji 4 I88. The carriage 35 carries a lug 89 which spring 51 would normally tend to,` ttenuatei 1vis adapted to strike the lever 88; the latter tending to tighten the spring 86 and' act as a bufi'er -for the carriage 3 5 so as to prevent the anti-friction roller 38 from pounding on the cam 17.

The 'hand wheel 73 is slotted at 'looj l A Y In order that theoperation will be easily understood, it will be assumed that the machine is at present equipped for writing and signing a letter; the mainlcylinder 3 being set up to print the body of the letter' and the carriage 35 carrying an electrotype to print the signature.

The operation is as follows: The blank paper is inserted at and between the cylinder 3 and the platen roller 5. The handle 4 is then turned in the direction of the arrow, Fig. 1, and the paper is thereby fed toward the top of the rubber coated roller 71. In passing between the cylinder 3 and the platen roller` 5, the body d of the letter is printed thereon. D being rotated, the gear 28 imparts motion to the chain of gears 23, 19 and 16, and 23, 27, 13, 26, 12 and 11. The gear 16, being keyed to the sleeve 15 rotates the cams 17 and 18. The cam 18 acts against the anti-friction roller 43 to lower the lever 29, (see Fig. 9), and thereby pull the chain 40. In so doing, the eccentric trunnions 34 are turned (in the direction indicated by an arrow, Fig. 11) against the action of the torsion spring 42, so as to lower the shaft 33 and necessarily the carriage 35. lVhen the carriage 35 has been lowered the prescribed distance, the anti-friction roller 38 is opposite a steep portion of the cam 17 so that the spring 76 will contract and swing the carriage 35 so that the electrotype 37 will contact with the paper to print the signature. The roller 71 is driven 'through the medium of the pin 71a extending` into the slot 13a and, as the gear 13 is timed to give the roller 71 the same surface speed as the cylinder 3, feeds the finished letter toward the conveying wheels or rollers 80-83 from where they are ejected. After the electrotype has finished printing, (Fig. 12) the cam 18 passes away from the anti-friction roller 43, and the torsion spring 42 turns the trunnions 34 in the direction of the arrow, Fig. 13, and by so doing, winds the chain 40 thereon and raises the shaft 33 and carriage 35. As the chain 4() is wound on the trunnion 34, the lever 29 will be raised t0 the position shown in Fig. 13. After the electrotype has been raised, the cam 17 engages the anti-friction roller 38 and swings it into the position shown in Fig. 11, and the operation is again re eated to print the next letter. When it is esired to change the position of the elee'trotype impression with respect to the body portion of the letter, the clamp band 20 is loosened and the hand wheel 20 turned until the gear 16 moves ont ot' mesh with the gear 19.

The cams 17 and 18 can then be shittedto' any desired position, after which by again turning the hand wheel 2" *he gear 16'can be brought into mesh wit the gear 19. Thus it willy be noticed that v`h my invention, a signature or other impression can As the cylinder 3 is' be made on any desired position of a sheet of paper, and that the camscan readily be adjusted to change the time and position ot the impression. For example, if the carriage 35 is operating to print a signature at the extreme bottom of the letter and it is desired to have the signature printed in another position with respect to the body of the letter, it is only necessary 'to turn the 1 hand wheel 2Oa to unmesh the gears 16 and 19 and turn the cams 17 and 18 to a position l that will allow the carriage 35 to move in contact with the roller 71 at the proper time to make the impression in the desired place. l The roller 71 may be bodily adjusted to ward or from the carriage 35 by loosening the lever 75 and turning the hand wheel 73 to vary the character of the impression. Or, if it is desired to change the alinement of the roller 71 with respect to the carriage, it is only necessary to turn the eccentric nut 7'f.

The movement of the carriage 35 effects the feeding ot the inked ribbon 48 over the face of the electrotype 37 in'the following manner: Considering that the shifting level' 6() has been manually lowered to the posi tion shown in Fig. 6, the forward movement of the carriage, (see arrow, Fig. 6l allows the spring 52 to slide the pawl 55 over one of the teeth of the ratchet wheel 54 without turning the latter. On the return l movement of the carriage 35, the latter will move faster than and away from the pawl 55, and, as the spool 47 having the ratchet wheel 54 thereon is directly connected to the carriage 35, the ratchet wheel 54 and spool 47 will be rotated thereby. causing the inked ribbon 48 to be wound on the spool 47 to bring a fresh portion of the said inked ribbon .into contact with the electrotype 37. 'hen the spool 46 is nearly empty, the shifting lever 60 can be raised until the uf)- per tongue of the pawl 55 meshes with the teeth of the ratchet wheel 53, and the spool 46 is rotated to rewind the inked ribbon thereon by the movement of the carriage 35 in exactly the same manner as above described relative to the. spool 47. The lever 6() is locked in its raised position owing to the fact that the lower end oi the V-shaped slot- 67 will be pressed against the pin (it). The spring 51 will act as a safety means to prevent the ends of the inked ribbon from being torn away from their respective spools in the operator fails to notice when either spool becomes nearly empty: the spring 51 being just strong enough fo resist. without stretching. thtl friction necessar)Y to rotate the spools under ordinary conditions. but will stretch it any additional strength of the sp1-ing 51, the.pa\vl 5T will move in the same path with the carriage 35 and the' spring 5l will stretch.

In the form of my invention shown in Fig.v 14, I have dispensed with the chain and substituted an arm 907 hivingan antifriction roller 01. at one end.Y-attached to a split clamp' hand on one ot the trunnions A cam '02 on the sleeve 13 operates against the anti-friction roller 91 to move the arm and thereby turn the trunnion to lower the carriage 515. I may use the torsion spring 42 to operate against the action of the cam 90 for raising the carriage 35, or I can use a tension spring 91. In the latter case, the saidlcnsion spring)r 04 has one end attached to a projection 95 on the frame and the other end attached to, a lever 96 extending from one of the tronnions 34. Also in Fig. 14, I have shown means for adjusting the carriage 35 to a1 low for variable printing impressions. In' this latter case, the trunnion 30 is milled overa portion of its surface to form worm teeth 97 and the split band 98 placed thereon. The split band may be clamped to the said trunnion by means of a screw 09. An extension 100 of the band 08 forms the housing tor' a rotatable worm 101 which meshes with the teeth 9T and has a'slot 103 formed therein. When it is desired to raise or lower the shaft 55:; and carriage 35 independently of the regular operation of the machine, the-screw 09 is loosened and the'worm 101 turned by a screw driver o1` 'other means. For most classes of Work, I prefer to use the' construction of the printu ing elements shown in Fig. 11 as the same permits a very accurate adjustment.

In Figs. 15 and 16, I have shown a construction Where the carriage adjustment means can be used, in case I desire to use the chain formation. In cases where it is desired to attain a very accurate adjustment of the cams to properly position the electrotype impression with respect to the body ofthe letter, I have shown (Fig. 1S) a construction where the cams can be adjusted without throwing the gears 10 and 19 out ot' mesh.`

The form shown in Fig. 10 shows means for supplying ink direct to the eloctrotype by means of a series of rollers 101..` 103 and 106, journaled in a'tray 107. The hottom ot the tray `107 is shaped so asilo form drip receptacles 108 and 1 00 for the rollers 10.7 and 106 respectively .and an inl( `fountain 110 into which the roller 104 extends.` The ,tray 107 has bars 111 connected thereto and adapted to slide within slideways 112 iu the frames 6 and 7 and to be locked by set screws 111, A gear 1.13 meshes with the gear 1.6 and a gear 114 loose on the roller 105. The gear 114 meshes with a gear 115 fixed to the roller 106. Another gear 114 Vis keyed to the roller 10J and meshes with gears 110 and 11T .fixed to) the rollers 104 and 100 rcspectively. Adjusting inca for the roller 107i comprise a set screw 118 and a (xnnprcssion spring' 111:1 which are housed within the tray 10T and adapted to press against the axle of the roller 10i. and to move the latter toward or away from the roller 10? when the set screw 11S is turned. Motion is imparted p through the gears Milf-11S to the roller 104 which conveys the ink to the roller lt'which in turn carrics the ink to the roller 100. The electrotype during the forward swing ot the Carriage contacts with the roller 100 and receives ink therefrom. The roller 106 also tends to feed the carriage atthe same time as the latter is being inked, thus insuring an equal distribution of ink over the electrotype.

In Fiff.' '30. I have shinvn another form of supplyinrY ink directly to the electrotype and consistsmt two "rotatably mounted rollers 120 and 1:21. .The roller 120 covered with an ahsorbcm .natcrial which is kept saturated with ink. ln operation. the surlace of the roller lift is. icpt cow-rml with ink b v tiring in contact with the roller 190 and thecarriace movesy the clectrotype in contact with the roller 121 and receives a coatingF of -inlr therefrom. d ip pan 122 is placed lnrneath the rollers 120 and 1:21 so as to catch any inl( that' may drop there from.

lVhile I ha vc described the carriage 35 as carrying an electrotype of a signature in the operationvof my invention. it will be under stood that any kind of type can he placed within the grooves oi' the carriage to print letter heads or othc;` desirable n'laterial. Also. two or more carriages can be arranged in tandem form to print different imprcssions in one passage of the paper through vthc machine.

lly using.r the carriage 21.3 in the manner describetLI am ahle to attain cleabcnt even impressions on long and short paper, and thc type carrying area of the bottom of the 'ari-lage may he of any size.

It will he further nnderstfimd that while 'l' have illustrated and .described my invention in combination with a rotary printing machine my invention can be used with other forms of machines or independently of another machine.
