` il The' Schedule referred to in these Letters Patent and making part of the same.
To all whom, 'it m'ay concern f Beit known that I, Mnnm'r'r (litmiv, ot' Rochester, in the county of Monroe, and Stute ot' New York, lim-'einventedttnew :ind usei'ul In'iprovement in Printing-1resses; und I'do hereby dechire that the. t'ollo\ving is a, full, cleer,nnd` exuct description ot' the consume, rcierencc being had to the accompanying drawings, nmkingnv port ot' thisslieciticetion, in which`- Figure 1 is :t side elevation, showing the construction and relative'nrrnngemeut of the wu'vs and pulleys or guides which give direction to the roller-eu-I'i'inge.

This invention consistsk First, in :in improved construction ot' the ways which guide the movement ot' the iuking-rollers, suid we vs bearing such relation to the nlcdistributingcyl- ,inders as to insure :ui enst movement to said rollers,
' und, :it the sume time, unse them free from the distributiiigt-cylinders on coming in Contact with, or leuving the sinne, mid thus :ivoid the tcuringot' rollers so iiequent in presses where the t'oriner are drnwn over the dist-i'iln1tingcyliluiers. l
Second, in the ,construction und use otl cuius, which the gripper or risk'et-ii'nger,
govern the movements ot' the drew-hairs, in cmmection with the driving-ermilcs.
Third, in t compound lever i'or giving motion to the hiking-rollers, one 'ot' the .single levers ol` which `:ilwm/s hns e positive motion :it the time oi'inlting the typesmvhile the other parts muy be dismmnectcd, il' desired, leziving the inking-rollers upon the distributing-cylinder or cylinders for u longer distrilnxtimi. When the simple levers forming the compound lever ure connected, und `not together, szlid inking-rollers haven. positive motion in both directionsover the types, never beingr :illowcd to rundown by their own weight. Y y f Fourth, in ai device for disconnecting the single lc- -vers ot' which such compound lever is nnule up, und rendering one portion ,of the sume, together with the inking-roliers, inoperative, while the reimiining lever continues in the positive motion above described.
Fifth', in n'cntchfor preventing thc sziid diseonnecting-device from being released :it :my other time tlm-u when the single levers, composing the compound lever, v:ire in proper position for conneciion.
Sixth, in curved wedges` or sleeves, phnfcd lwtweeu the pins, trmmions, or journals, which susto-in the thrust or draught of the impression ot' :t printing, press, :ind the bearings of such pins or journnls, Afor adjusting the degree ot'the-impression.
Seventh, in uset-hitch, t'or ndjusting the dele-ree'ot'v v'the impression, in'eonneetion willi the curved wedges or sleeves :Lbove referred to. v
,lightlu insprings, l|nlia-rubbcr packing, or other elaistie nutterinl, to tithe oii the positive pressure ot'the ink-ibuntuin set-screws, so :is to prevent the bilnling.; ot" the gziuge or cut-ott' upon `the suriiu-e ot' the roller which fee-ds the inlii'ronl the trough or funk.
Ninth, in placingon the lover-proiection oi' the plntrm-rocker n lug, which, in connection vwith :tiizrnge or stop ou the tranne-work, holds 'the pinten in position during the impression.
Tenth, in giving the. typo-bod u. bnckwnrd inclinetion, when used with u rocking, rolling, vibrating, or oscillatingr platen, for the purpose o't' iii-stelling the form to the i'nce of the bed by its own grovity, preventing loose type trom wol/hing ont, :md the. form bngging. l lu the dra-wingslhe way al ai* lr a,'wjiich governs the direction oi' the. rollers Il, 2, 3, hns :i straightpau-t, in line with the time ofthe types, and :t series ot' curves :it `thutlmrt nearest the ink-distiilmting cylinder or cylinders.V
This series ot' curves maybe varied iordiiierent numbers ot'hiking-rollers.` ln iig. l, threehiking-rollers nrc. represented, l p :Ls-resting upon the distrilmtingfeylinders 4 lhe direction of movement ot' the wheels or guides acts in unison-with the strrd or wheel (J,
back again to their' position 'l' 8 determines the direction of the hiking-rollers, as they leave and approach the distrilrating-cylinders.
Roller 1 simply cornes in contact with cylinder- 5, and leaves it directly, passing toward cylinder 4. At the same time the rollers 2 and 3 are lifted ottl from cylinder 4, without being drawn over' its surface..
This is donc by the movement oi' the wheels or guides S into the curve di.
As roller I nears cylinder' 4, it also is raised clear of said cylinder, bythe passage of wheels or guides 7 into curve af. The wheels or guides 7 and 8 then both pass through curve ai' into the straiglrt part ai.
It will be seen that the passage of tile wheels or guides 8, through the series of crrrves a e2 a", into the straight way ci, will give an easy, undulating motion to the rollers, and, at the same time, willv pre vent the' composition ofthe rollers 1, 2, 3, from being torn, as it is liable to be when said rollers are drawn over the surfaces ot the cylinders in the usual manner.
lt, will also be seen that this arrangement so re-` moves-the hiking-rollers and distributing-cylinders from the plane ot' the face of the types as to allow the printing of sheets larger than the face of the platen, or with margins extending beyond the face ot' the platen, and thus prevents the contact of said sheets with the ink upon said rollers and cylinders.
ln lig. 4, the traverse-cam U, iuconnection wit-lr stud or wheel i, governs the 'movementot' draw-bar l), while thccrank-pin e is passing through the slotd.
l)uring-a part otthe sweep of the crank-pin e, it 'that part of the traverse through which the stud'or wlrecl is passing` being concentric with the crank-pin.
The remainder oi' the traverse being eccentric to the crank-pin, allows the said movement oi' the latter in the slot (l, at the same time holding the draw-bar quiet, so as to impart a time ot' perfect rest to the :plate The traverse may either be a cap, as represented, to be attached to the crank-pin outside of thecdraw-har, or it may form part ot' the crank-wheel inside of the drznv--barn l 'lhe combination ot' levers for giving motion to the inking-rollcr's is a rranged as follows:
ll, ligs. 'l and 2, is a shaft, to which roller-arms I,--
iig. l, are attached, through whichtby any means ot' connection, motion is given to the inking-rollcrs of a press.
'.lo shaft H, l attach a lever', K, which may be entirely separate from the roller-arms or levers above mentioned, or may form part ot' oneof them.
l also pivotlanothcr lever, L, at H2, tigs. 2 and 3, said lever having a positive vibra-ting motion, at the iinr e,tbr moving the inking-roller's over the types, and
on the*distributing-cylindcrs, such positive. motion being impart-ed by a stud or whccl,(), working in positive traverse-earn U' ot' the main spur-wheel l", to which traverse-earn, nrotion is communicated by the, driving-shaft F.
Y I connect the levers L and K by means of a hookconncction, M, pivoted tolever K, at E", and hooked upon a strrd or pin, E, attached to lever L.
lt will be seen, that when levers L and K are. in the posit-ion shown in tig. isi, by raising the hook M iom the stud Ef, the lever L will be ,allowed its positive movement;without motion ofthe lever K, and, whenever' the hook )l is hooked upon the strul ll, both levers L and K will have a positive rrrotion, acting as a connected compound lever.
As lever L acts through the shaft H, to which the roller-arms or roller-levers arc attached, it will be seen lthat the inking-rollcrs, when moved 'in either direction over the types, will have a. positive. motion, or that said rollers may be retained any length of time upon the inking-cylindcrs, for distribution, by disconnecting the levers L and K, when in the position'represented in lig. 3.
4said wedge For disconnecting said levers, I use the lever N, with short` arms y, said lever being pivoted atf.
It will be seen, in fig. 3, that by working the lever N, the short arm g will raise the hook M, and discouneet the levers L K. \Vhcn the hook M is lifted end of short arm g ot' lever N moves toa position in front of a-projecting portion, 1', of lever K, which portion acts as a stop to prevent any movement of lever' K dlp-ing a complete vibration, or a number of vibrations, ot' lever L.
A drip-hook or latch, I, drops into a connection with a rnortisc in the end ot' the short 'arm g, and prevents thc lever N from being worked, except when the levers" L and K are in juxtaposition.
The latch l is relieved from the nrortise inthe end of short arm g by a projection, I?, drivingr against a profrorn the stud E", the
ejection, t", of said latch.
1twill be seen, that as vsoon as lever L 'moves away from lever K, thc latch I will fall into position, and prevent the working of lever' N at the wrong time, and prevent dropping ot' hook-connection M.
Upon thc pins, trnnnions, orjournals I, igs. 10, 11, 12, and 13, which sustain the force or draught of the impression ot' a printing-press, I place curved wedges or sleeves i` or i, the concave face of' said wedges or sleeves being concentric with and in contact with said pins, trnnnions, orjournals I, said wedges or sleeves being placed between said pins,- trnnnions, or and their journal-boxes or bearings.
The convex or outside face ot' said wedge or sleeve is concentric with and in contact with a part or wlrol'e of the concave or inner' face ot' said box or bearings Irl, the latter rrr-.1de either movable or stationary, in connection with the frame-work, type-bed,o'r platen, said trarne-work, bed, or platen being constructed in any manner', whether the tace of said type-bed, or thel plate for receiving the sheet, is plane, cylindrical, segment-al, or ot anyot-her construction; or whether' the outside box or bearing M (either movable or stationary) is rrscd either in connection with impressionbars, connection-rods, draw-bars, or their equivalents, or forms apart of the same.
. By turning the sleeve or wedge i i? to ditere'nt positions about the trnnniorr, pin, or journal I, the impression may be changed, to any degree, from zero to the strongest power ot the press, according as the position of said trunnion, pin, or journal is thus changed wit-h respect to t-lre box or bearing M3.
As the surface ot' pin or journal I and concave face ot' wedge or sleeve t" i, are concentric with each other', and the outside face ot' -said wedge or sleeve and the 'face of the box or bearing are concentric with each other, said outside and inside faces ot said wedge or sleeve. being only slightly eccentric wit-lr each other, it Iwill he seen, by referring to tigs. 11 and '12, that the tendency ot thc wedge or sleeve to turn under draught or l'rressurc, when set in any position, is very slight. vIn tig. 1l the. wedge v" is 'represented as a complete crescent, and in tig. 12,"it is increased toa. sleeve. It will be seen, that when under pressure or draught, onehaltl ot' said wedge or sleevetends to move in one direction, and the other half in an opposite direction, as shown b v the direction ofthe arrows in tig-1l and iig. 12. As but little diti'crence in the positions of or sleeve is necessary for any change required in the impression, the variation between the tendencies to turn in either' direction will be slight, and more than overcome by the friction of the surfaces under pressure or draught. No device, therefore, is necessary for holding the wedge o-r sleeve in posit-ion while under pressure or., draught. Sonie devicc,'howcver, isv necessary for moving and setting said wedge or sleeve` to the degree of impression required, and, whcretwo or nrore of said wedges or sleeves actin rrrrisorr, sornc device is required for connecting them ftogcthcr.
journals v In the latter ease, Iuse the connect-ii.|g-b ar T, tig. 14, or an equivalent. i
As thef'riction ot' thel bearing-surfaces in 11 and 12, more than overcomes the tendency` ot' the crescent Ai2 to turn under pressure or draught, the position of the crescent cannot be changed when desired, with ease, when any great amount of pressure or draught remains continuous. In -such a case, I cut one limb et' the crescentaway, more or less, thus destroying the equipoise of the .two limbs, as shown in fig. 10, or cut one limb of' the crescent entirely away, forming the curved wedge 'i2 'of iig. 13. In that part of' the press A2, fig. 7, which contains or supports the pin, trunnion, or' journal, with `which said wedge or sleeve comes in contact, I place a conical-headed screw, the head of which forms a V- shaped catch, L2, for the catch-hook XV, in whatever position the screw L2 may be turned.
In fig. 1, T represents a projection upon the sleeve or wedge fi, i2, or a bar, connecting Vtwo or more wedges vor sleeves,`when more. than` one are required. Upon the projection or barfl, is a handle, of' the fbllowing construction 'llhrough the socket U passes a rod, with a .ball or handle, Y. Upon said rod is a socket-spring, a, tig. 8, and attached tothe cud of the rod, opposite handle V, is the catch -hook NV. By pressing upon the ball or handle V, the hook W will be released from the catch L2, and the wedge or sleeve vi iP', iigs. 1 and 14, may be turned, at will, to any position within the scope of its movement. To set the impression to any particular degree desired, it will only be necessary to move the cone L2, by turning the screw to which it is attached, out, or further into the supporting-part A2, and bring-4 ing the hook W' land cone l? into connection. This will vary the position ot' bar or project-ion l`, and thus vary the position of' wedge or sleeve 1' i2, figs. lV and'14. y y
The manner of working the ink-fountain and vibrat ing feed-roller is represented in fig. (i.
.The crooked lever V* works the pawl V, by contact with a cam, Y, on thc crank-wheel F.
rI he ink is fed from the fbuntain-roller u2 on to the vibrating roller Y, while rollers n2 and V are in contact, such feeding being effected bythe working ot' the lpawl Y and ratchet nl; and thesame movement of' said pawl being continued, forces the vibrating feedroller V6 against the distribnting-cylinder 4, said pawl pressing,r against the vibrating yoke V2. 'lhisrequires but one movement f'or feeding the ink from the fountain on to the vibrating feed-roller, and also for working the vibrating feed-roller to and from the distrib# uting-cylimler.
I, coat or line the tank or shell n, fig. 9, which coutainsthe ink, ot' an ink-fountain, with porcelain or other substance non-corrosive to ink, to prevent the metallic substance of said tank or shell f'rom eorroding or discoloring the ink. v
The construction of' the bed l is shown in tig. 15, showing an end view and a longitudinal plane section.
The f'ace of the bed is represented by B, the Vlongi-I tudinal braces are Vrepresented by 7' l", und `the transverse braces by l. y
The core-prints or vent-holes, made in casting,` are represented by If, and F5.
The several braces ot' the bed converge to a ecmmony bearing-line, E, which corresponds with the driving-shaft Ill of fig. 2.
The bed, constructcdyl-s above described, may be made, together with the supporting frame-work, in one piece. In such ease, said frame-work will form the end braces l, the be`d still remaining a hollow-chainbered shell, the core-prints making the openings er vent-holes I1" F5 through the` sides of the supporting frame-work, in those parts which fbrm the end braces. In applying thc spring material to the ink-fbuntain f 3, fig. 17,on the ink-feed roller S", 17, I use the following method, as one ot' the most convenient in manufacturing and dura-bib for use:
`l place a piece or pieces ot' rubber packing or other elastic material, h, upon the knife or cut-off f, said material being removed far enough from the edge of' 'said knife as to avoid contact with the ink; I tben place upon this elastic material a thin bearing-plate or slips, f7, to receive the direct pressure off the setscrews e Tile pressure of said set-screws is conveyed indirectly to the ent-ofi' f3, but prevented from being a positive lirresistible pressure by the intermediate elas-v cut ott' on any part of the length of the roller S", without binding 0r set-ting said roller.` Y
The gauge thus constructed is 'made movable, so lthat it may be cleaned separately from the roller The holesn u, tig. 16, in the fi'isket-finger, are made large enough for small feed-guides to be placed under them 'on the tympan-sheet. These holes have two prominent advantages over notches cutinto the side of the finger: til-st, the finger is lunch stronger, having material left on all sides of the hole; and second,
sheet, holding it in place more firmly, also preventing tearing or wearing Vfrail sheets, by contact with the corners made by notching the finger.
S, tigs. 1 and .5, is the lug, placed on the lever-proieetion of' the platen-support or rocker It, which draws upon the upper face of' the flange Y, while projection S2 draws upon the under facc. ot' said flange, for the purpose ot' firmly holdin,"r the platen in position during the time for taking 'the'ilnpressiolt The bed I3,- tigs. l. land 2, is made tovincline ba-ckward at any angle between fbrty-tive degrees and the, vert-ical, in order that the type may rest ,npon' the face oi' saidA bed, by its own gravity, preventing the loose type from workl ter from bagging.
connection with a cylinder, b v (l. l. Gordon, and also in connection with a reciprocating platen inclined par-4 allel to the bed, by P. "\V. liatcher` v I'Ieretofbre the general construction ot' presses has precluded the use of abed inclined backward at the. same time with a vibrating, oscillating, or rocking platen, on account oi' the necessarily extended sweep of' the platen.
.By constructing a platen ot" the general nature of the one here shown, the sweep is unitevi-allyshortened, thus allowing the use of such a bed.
Having thus described my invent-ion,
That I claim as new, and desire to secure by I.efters latent, is
1. In `a `printing-press, such a construction et tluways in or ou which the wheels or guides of the ink-` ing-rollers run, shall raise such hiking-rollers free from the distributing-cylinder or cylinders when appreaching or leaving.. the same, substantially and -f'or the purpose described.

'5. The latch l?, combined with the levers L Ii, for the purpose of holding lever K und hooke'ouncetion M in position f'or reconnection, and preventing the gauge, to prevent the binding of' the knif'e or cnt-off tic material z, so that the fion-1 ot' ink can be entirely the entire edge of the finger is left for clamping the Y ng out of' the f'orm, and the lati I am aware 'that an inclined bed has been used `in release of lever N at an improper time, substantially as specified. 4 l Y 6. The wedge or sleeve t' i2, pin, truunion, or journal I, box or bearing M", and adjusting-bar T, combined substantially as and'for the `purpose set forth'.
