Specification forming part of Letters` Patent No.v 7,878, dated January 1, 1851; Reissue No. 5719, dated Tnnuary 19, 1858. v f l To all whom vit may concern Be it known that I, STEPHEN P. Recetas, of Boston, in the county of Suffolk'and lState of Massaehusettshave invented certain new and useful Improvements in Printing-Presses; and I do hereby declare that the following description, taken in connection with thev accompa-nyin g drawings hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, by which my invention may be distinguished from other-s of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent.

The inking apparatus consists of aseries of rollers, G G G G', Fig'. 3, Piate 2,l arranged side by side inthe slotted' boxes H' H H H, Ste., in each of the rotating cheek-plates I`I y[ I, Figs. 3, 4, and 5, Plate 2, which plates are `O O in the ends of the rods 1j 1 which rods are connected to the spinal springsQ Q arranged as shownin Fig. 4,.so as 'to permit the desired play of saidhuttons. The journals of `one of the hiking-rollers G rest upon sliding -bearers 1t It, which niove up and down, and

are guided by the slots S S and pins TT, Figs. 4 and 9, Plate 2|. The sliding motion of these bearers is effected by means of a horir/.ontal stud att-ached to the exterior of said bearers, which asthe rollers turn round on the cylinder F F l" come in contact withthlc stationary cams ,U U on the side frame-work, and press the roller G" upward, so as to bring it in contact with the ink-.delivering roll V V in the fountain W W after each passage of the rolls over the form. The raising of this roll G i'roin the distributing cylinder FfF F ,l

enables it to take the ink from the deliveryroll, and leaves said roll G' free to turn and take the layer of ink from the delivery-roll of the full width which it ispermittcd to give out. The delivery-roller V V is scored transversely, iu the way now., commonly practiced byme, and has combined with it an adjustable-scraper, u. a., regulated bythe screws b b, tte., so as to deliver a thin -thn or sheet of in-k to the roller G. The. fountain W W and roller V V--may be lnoved horizontally toward the distribuling-.cylinder by means of the stationary screws c e, operating :with the nut-plates d d, attached tosaid'fountain A in al manner which will be readily understood The delivering ot' the ink frcnnth'c fountain ortho turning` of the deliveringfroilf1.VV is regulated or varied by the fi'ollowingl arrangement or combination of the mechanical devices: 0n the journal of. said delivering-roll a grooved ratchet-wheel, e e, Figs. 1 and 2, Plate l, is -irmly fastened, havngteeth on each side of the groove. A band, ff, passes under and over this wheel, and has a weight, g, attached to its lower end, and pawl h, secured to that part which passes over said wheel, which paw] engages with the teeth of the ratchetwhcel, as shown in said gures. Near its other end saidband isattached to the top of a leveristud, i, which is moved by a roll, k, fastened to the inner face of the gear- `wheel M, before referred to. end of said band passes through a staple, l, on the side of the stop-leve" n gn, the band having a proper stop on its end which en- 'gages or abuts against the staple l of the stoplever. The said 'stop-lever n 'n and the leverstud i have' proper filiera on the frame-work, and by pushing the former forward or baclc ward the weight g will pull the pawl h, over 'a lesser or greater number of teeth on the ratchet wheel c e, and the lever-stud i, operated by the roll k on the gear-wheel M, will turn Asaid 4wheel and the delivering-roll correspondingly, the'stop on the end ot' the band ff, which engages with the staple vl of the stop-lever, arresting the descent of the weight g, and consequently at each revolution ofthe Ainking apparatus regulating thetake-up of `the p .ml on theV ratchet wheel e e.

In order to prevent the ink from getting on vthe tympan at each impression, I make' the bearers so as to move in when the impression is being produced, and out when the inkingrollers are passing over the form. This is etfected by making said bearers of the shape shown at() 0 0 in Figs. 3, 7, and 8, Ilatc 2,

and arrangingthem so as to slide forward and back, the backward motion being accomplished by' the spiral springsp p p p, which passv from one bearer to the other around the arms q q of the distributing-cylinder, and the forward 'motion .being produced by the caminder, as above described, the ,inkingrollers have continuous rotary motion, in lieu of a f reciprocating motion as is usual in presses, by

vwhich improvcn'ient much time and power is saved. 'The said ycylinder is held in position by means ofthe bent levers or dogs tt tt, f f which project from each end ot' the shaft au,

on which they tu'rnfeach being attached to ythe end of a spiral spring, ce, which operates j so as to turn tliem always to one position when they have been moved from they same. The `ends of the dogs t t t thave proper studs,

which engage with slots on the side of the 1distributingcyliiidcr, and the clieekplates I I, in revolving, throw each of said levers out ot' conneetion'with said cylinder alternately,

The extremev so as to let the inking-rollers pass round and always keep in contact with said cylinder. By these means the bed E remains stationary while the rolls Cr are carried over the i'orm by means ot' the revolving cheek plates i I.

It only remains for me now to describe the platen and the mode of operating the same,- together with the means used for holding the paper down on the same. The laten"`vV \V, Figs. 1 and2, Plate l, and'Fig. 3, Plate 2, is arranged so as'tobe adjustahleby means of the screws a: ai a: in the plairv yyof the vi brating frame y y z z, which trame turns on the shaft a', having-proper bearings in Ithe frame-work, and' is hung by.. means ofthe con necting-arms b b b" b to the eccentric points on the et'terior faces of the-revolving circular plate c' and the gear-wheel M, both of which are fixed to the revolvingshaft K K. Ihe revolutions. of the said plate c' and wheel M, it will be seen, will cause the platen' to vibrate or move alternately to the form to get an impression and from the same to get a new sheet or card, the lowest inclined position which it takes being the most convenient for placing the sheet. A gage-plate, d', extending across.

the-.end ot' an arm, l e', (secured by the screw- `clamp at f'to the vibrating framey y z 2,)

has diverging springs g g', Fig. 11,`secured'to its upper side, which catch the edge of the sheet, .and a spring'holder, h h', secured ,by

the same clamp to the vibratin g frame directly over said gageforms with the vibrating platen, a pair of nippers, as it were, to hold the sheet firmly against the tympan (supportedv by the platen-plate) so as to disengage it from the form.

In printing cards I use a gage-bant' @'with a projecting lip, k', under which the card slides, the arm of which bar is secured by the screwcla-mp f to the vibrating frame, so as to move up to the form with the platen; but when the,

platen is receding the under side of the arm 'i tabuts against a finger, l', on the crankm', whichallows the platen to open or descend from it and let the card which has been printed slip down into a proper receptacle beneath the press. The crank m is then turned by means -of the arms n' n', 1which connect said crank with one of the connectingarms b b', before referred to, and by so turning said crank the Vfinger l' is moved downward and permits the descent of the gage-bar i i against thc platen so as to receive another card.

Having thus described my improvements in.

printing-presses, I shall state my claim, as follows; ,l

What I to have secured to me by Letters Patenti, is-

1'.v The gage-bar for cards, hereinabove referred to, in combination with the vibrating platen and stop-finger and crank which operates the same, in thel manner and for the purpose hereinabove described. l Y

' 2. The use of a segment of a cylinder in combination with the stationary form-bed, so that the rotary inking apparatus may move claim as my invention, and desire bed,- the revolving cheek-plates l I, f'or cnrryover the form and then after taking ink from combining' with the (luiken/roller n grooved the fountain distribute it on Suid Cylinder, as ratchet-wheel and Weighted pnwl-bnnil, operhereinabove set forth. ating with the lever-stud,ean1-1'olle1, anni stop- 3. In combination with the stationary forlnlever, substantially as hereinabove Specified. 6. Supporting thejonrnnls of one of the inking rollers on slitlingbearers so that it may be moved np against the (leliveringroll by ineens of' studs on said bearers and (mans, operating the sume ns hereinabove set fort-b.
