SAMUEL A. NEIIDICH, OI EDGEWATEB PARK, NEW JERSEY, ASSIGNOR TO THE AMERICAN MULTIGRAPH COMPANY, OF CLEVELAND, OHIO, A CORPORATION INKING APPARATUS.

Specification 01' Letters Patent.

Patented Mar. 3, 1914.

Original application filed September 28, 1910, Serial No. 584,202. Divided and this application filed September To all whom. it may concern:

Be it known that I, SAMUEL A. NEIDICH, of Edgewater Park, in the State of New Jersey, have invented a certain new and useful Improvement in Inking Apparatus, whereof the following is a specification, reterenee being had to the accompanying drawings.

This a )plication is a division of application Serial #584,202 filed September 28, 1910, for Letters Patent of the United States for improvement in duplicating machines.

My invention relates to machines adapted for printing impressions having the appearance of being manually typewritten, and may be employed with particular advantage in making assimilated printed and typewritten work in accordance with the process described in Letters Patent of the United States #640,013, granted to me December 26th, 1899.

As hereinafter described, my invention is embodied in a machine comprising a rotary printing drum and a cooperative rotary platen. Said drum is adapted to rint from type set in a flexible chasc detac iably held on said drum, and, the ink for the printed impression is derived from a transfer sheet of textile fabric which is detachably held stationary on said drum over the type faces. Said sheet is sup lied with ink for each impression by mecianism including a series of rollers interposed between said drum and an ink fountain, the terminal transfer roller being presented against said sheet and the other rollers cooperating to intermittently withdraw a definite, adjustably variable amount of ink from said fountain and deposit it upon said transfer roller.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings :-Figure I is an elevation of the left hand side of a duplicatio machine embodying my invention. Fig. II is a fragmentary elevation of the right land side of said machine. Fig. III is a fragmentary vertical sectional view, taken on the line III, III in Figs. IV and V. Fig. IV is a fragmentary plan view of that portion of said machine shown at the left hand side of Fig. I. Fig. V is a vertical sectional view, taken on the line V, V in Figs. I, II,

III and IV. Fig. VI is an end view of the ratchet clutch mechanism for intermittently rotating the inking rollers. Fig. VII is a fragmentary plan sectional view of said clutch mechanism.

In said figures; the duplicating machine frame 1 supports the rotary printing drum 8, having at one end of its shaft the operating ham 1e 12. Said drum 8 carries type and is provided with means to detachably hold stretched over said type in stationary relation therewith, the ink transfer sheet of textile fabric shown in Fig. III. Either said ink transfer sheet 50 or the type 25 may be reinked after each printing impression by the mechanism mounted in the carriage 63 under the removable cover 64: normally retained by the thumb screws 65. Said carriage being fitted to slide in the bearings 66 on said frame indicated in Fig. V, is conveniently shifted toward and away from said drum 8 by the shaft 67 which as shown in Fig. III has the bearing blocks 68 arranged to slide in the carriage flanges (it), and the eccentrics 70 journaled in the bearings 71 in said frame. Said shaft 67 may be turned by the handle 72 shown in Figs. II and IV having at its free end the spring ressed plunger detent 73, to engage tie soctets 74 and 75 in the plate 77 on said frame; the arrangement being such that when said handle 72 is raised said carriage 68 is shifted toward the drum 8, to operative position, and when said handle is lowered said carriage is shifted away from said drum, to inoperative position. A]- thou h the extent of the backward and forwar movement of said carriage 63 is limited by the locations of said sockets 74 and 75; said handle 72 may'be rotatably ad- {usted in connection with' said shaft (37, raving the crown clutch hub 79 fitted to engage the crown clutch collar 80 pinned on said shaft; said handle being rigidly socured in adjusted relation with said shaft by the screw 81 shown in Figs. II and IV. Said inking mechanism comprises five rollers, including the rubber faced ink transfer roller 82 which when said handle 72 is upturned to the position shown in Figs. 11 and IV is presented a aiust said transfer sheet 50 as shown in ig. III, to transfer ink to said sheet. Said roller 82 has IUD the gear 84engaging the gear 86 on the drum 8 so astorotate with the latter, and 1S journaled on the shaft 83having the ec- -;cen tric's..85 journaled in said carria' e 63. Said shaft 83 is rotatably 'adjustabe but is normally held stationary by the set screw 88. The other four rollers of the inking mechanism have means coiiperating to intermittently" withdraw a definite, ad'ustably a'ariable amount of ink from the ountain 87 and deposit it on said transfer roller 82.- As indicatedvin Figs. II and III said ink fountain 87 is detaohabl connected with said carriage 03 bythe tuunb screws 89 which extend through the brackets 90 on said carriage in engagement with said fountain; the latter being precisely located by the dowel ins 91 projecting from said brackets 90 into the socket plates 92 which are rigidly secured in adjustable relation with said fountain by the screws 94 and 95 shown in Figs. III and IV. As shown in Figs. III and IV, the metal faced roller 97 has its shaft 98 journaled in immovable hearings in said fountain, and, the rubber faced roller 100 has its shaft 101 journaled in the eccentric bearings 102 in said fountain. The sup ly of ink 103 in said fountain 87 is uphe d between said rollers 97 and 100 as shown in Fig. III; said rollers bein intermittently rotated in the direction 0 the arrows marked thereon to dispense said ink in a thin film on the surface of said roller 97 from which it is intermittently dofi'ed b the rubber faced dofi'er roller 104 which a ternately contacts with said roller 97 and with the metal faced distributing roller 105 and applies the ink to the latter which is continuously rotated solely by contact with said transfer roller 82. Said dofl'er roller 104 being loosely mounted upon its shaft 100 is only turned when in contact with said roller 97 or in contact with said distributing roller 105; said roller 104 being turned more than five revolutions in the direction of the arrow marked thereon in Fi III each time it contacts with the distri uting roller 105 but being turned in the opposite direction a fraction of a revolution when in contact with said roller 97. Said eccentric hearings 102 for said roller 100 have respective wing levers 108 arranged to be clamped in ad'usted position by the screws 109 on said fountain 87, so that, by turnin said bearings, the axis of rotation of suit? roller 100 may be adjusted toward and away from said roller 97, to var the pressure of contact of said rollers an thus =vary thethickness of the film of ink spread upon the dispensing roller 97; the lateral location and extent of said film of ink being limited b the ad'ustable gates 110 shown in Figs. II and IV. Said gates being wedge shaped are pressed between said rollers 97 and 100 by the spring arms 111 on the cross heads 112 which are adjustable toward and away from each other and are secured in adjusted position by the thumb nuts 113 on the bolts 114 which extend through slots in said fountain 87.

As shown in Figs. I and IV the rubber faced ink spreading roller 100 has the gear wheel 116 on its shaft 101 engaging the gear wheel 117 on the shaft 98 of the metal faced ink dispensing roller 97, so that as said rollers are turned together in the direction of the arrows in Fi s. III and IV, but at different speeds, the 111k 103 is drawn down between them and spread on said roller 97 in a film the thickness and extent of which has been adjustably predetermined. Referring to Figs. I, IV, VI, VII: In order to effect said differential turning movement of said rollers, the shaft 98 of said roller 97 has the gear 119 engaging the ratchet clutch gear 120, which is mtermittently turned by the crank head 121 having the pivoted, spring pressed pawl 122 engagin the ratchet 123 in said gear 120, so that the latter is turned in the direction of the arrow in Fig. VI whenever said head 121 is turned in that direction, but is released and remains stationary during reverse movement of said head. Said crank head 121 is fixed on one end of the shaft 100 of said dotl'er roller 104; both ends of said shaft being eccentric with respect to the central portion thereof upon which said roller 104 turns, so that as said shaft is rocked in its bearings 124 in the carria e 63 the axis of rotation of said roller 104 IS shifted back and forth as above described. Said crank head 121 has the sprin 125 shown in Fig. VII tending to turn 1t into the position where the tltlJUSiable stop screw 127 rests on the ledge 128 of the carriage 03 as shown in Fig. I, in which position said shaft 100 holds the roller 104 in contact with the distributing roller 105 so as to be rotated by the latter. However, said head 121 is intermittently rocked in the direction of the arrows shown in Fig. VI, by the itman 130 shown in Fig. I having the s ot 131 for the crank pin 132 on the crank 133. Said )in 132 has the block 134 to encounter the shoulder 135 on said sitman 130 to thrust the latter upwardly uring art of the continuous rotary movement 0 said crank 133 which is carried by the shaft 137 journaled'in the frame .1 and having the gear 138 shown in Fig. Ill, lixed thereon inside said frame. Said gear is continuously rotated by engagement with the gear 140 carried by the gear 141 journaled on the stationary stud shaft 142 in said frame; said gear 141 being engaged by the gear 143 on the shaft 144 which has the gen r 145 enga in the gear 147 on the main driving sia t 148 which is journaled in both side members of the frame I. Said shaft 144 has the worm fixed right. hand i side i'nember-v -of said frame 1.

said-"shaftl liii' has the wrist 'plate 160 with ,"the cra'nk pin. 101 engaging the .llltk 1G2 which at its opposite end is connected by 'the'pivot-pin'ltitl with tlie yoke 164 shown in Digs-I bar 166 which is fixed in said frame 1.

Said distributing'roller 105 rotates freely between theu )turnedends of said yoke 164 as shown in 1* igs.-III and V, but is lon itudinally reci rocated on its shaftv 170 y said yoke; sai shaft 170 bein journaled in said curriage'tifl as shown in ig. V. Said

shafts

83, 101 and 100 etc. are respectively provided with the normally stationary but rotatably adjustable eccentric bushings 85,

102 and 12; etc., so that said shafts may be adjusted in precise parallel relation with the axis of the printing drum 8, and, it may be observed that such construction not only simplifies'and facilitates the rimary assembling of the machine but a ords means to compensate for wear of the respective shafts, bearings and rollers.

The mechanism above described may be used as follows: The type being set in the desired form is attache to the drum- 8, and covered with the ink transfer sheet as shown in Fig. III. The ink gates 110 bein spaced and set in accordance wit-h the widt i and location of the desired impression, and ink of the proper color and consistency being stored between said rollers 97 and 100 as indicated in Fig. IV; the mechanism is rotated by thehandle 12 to dispense a sufficient quantity of said ink upon the rollers 97, 10+ and 105 to coat the transfer roller 82 with a film thereof sufficient to replace upon the transfer sheet 50 or type 25, after cachim )rcssion, the amount of ink which is remove therefrom by each impression of the type form.

The inking mechanism above described may be rendered inoperative by turning the lever 72 in the direction of the arrow marked thereon in Fig. II to withdraw the carriage 63 of the inking mechanism to in operative position without stopping the maciinc or interrupting the printing operation a'bove described; said in c transfer sheet 50 being saturated withink like the ribbon used on ordinary typewriting machines. However," if the ink fOI'illG printed impressions is-solely derived'from any textile fabric sa'id impressions must be successively lighter because of the depletion of ink from saidfabric, even thoughthe latter be moved between successive impressions to present differentregions thereof for such impressions. 'Therefore,.t he inking mechanism described is'advantagcous in that it is tar-51s 10' Hgea' {-156 on'flthe counter-gell ng jourhaled: a 'tlie 'beajringsf 158' onj it-he I and V which is upheld bylthe; screws-165 'so"asto slide freely on the crosspable'iof reiiiking saidsheet5O after each impression. so} to i maintain it uniformly inked'i'throughout' the o' eration of printing an'yfdes'ired'numbcr'of impressions; for in- 's tance,"several thousand impressions may be made-of uniform appearance during one continuous operation of the machine.

'I do not desire to limit myself to the employment of any fabric on the drum 8, to receive-the ink for the printed impressions as the faces of the type 25 may be directly "inked by the roller 82, said sheet 50 being employed to produce impressions resembling typewriting. Therefore, I do not desire to limit myself to the precise details of construction and arran cment above dc- Scribcd as it is obvious tint various modifications may be made therein without dcpartin from the essential features of my invention as defined in the appended claims.
