Leners Patent N 99,551, een February s, 1ero.

IMPRQVBMENT nl PRINTING'PRSBEB'.

ne `schedule referred to in :nm Lenen Pawn ssa are saure.

To all whom it may concern:

Be it known that I, Mnnnl'r'r GALLY, of Rochester, in the county of Monroe, and State of New York, have invented a new and improved Printing-Press, called The Eclipse and I do hereby declare-that d "the following is afull and exact description thereof,

, sition for making the impression, also the inclined ways E and F, and wheels or guides C and D, detached from other parts, and enlarged.

Figure 4 is a side elevation, showing like parts with those of tig. 3, with plate A in position of rest.

Figure' is a modification ofiparts ning. 'L l The first part of my'invention consists in the construction and use of inclined ways, which, in counection with Vwheels,rollers, or guides, shall govern 'and give direction to the-movement of a plate, iu such a manner, that an extended reciprocating movement' may be secured tothe face of said plate, by a much shorter movement of the part or parts which give motion to the plate without a corresponding disadvantage in leverage.

The second part of myinventionconsists in such a construction oi'an ink-fountain for printing-ink, as shall secure a. constant and even flow or conduct of ink from the fountain to the distributing-apparatus, when such ink is too short, or lard-like, to be taken up by the fountain-rollerv of fountains in common use.

The third part of my improvement consists in' an improved construction of a roller-carriage, on which a and therefore sensitive spring is used for giving elasticity to the movement ofthe inking-rollers, without necessitating any projection whatever of springs beyond the body ofthe rollercarriage.

The fourth part of my invention consistsiu so con-v structing, arranging, and connectingthe wedges used for changing' the force of impression ou both sides of `the press, as to secure an almost instant and accurato. change by a single adjustment, and, attire same time, allow the use of the same device for throwing oli the impression at will.

I will now describe more fully tue several parts of my invention, together with their operation.

The plate rollers, or guides' C and I), which move in or upon inclined ways E andF, inclined in opposite directions.

It will be seen, that the movement of wheel or guide D, down the incline F, will cause ythe movement of A, figs. 1 and 3,' is furnished with wheels,

wheel or guide C `up the opposite incline E, which will bring'plate A to the position shown in iig. 4.

It will also be seen,that if the wheels or guides C and .D are so arranged, as to bring the centre of gmv ity of plate A 'and collarAcombined, midway between said wheels or gides, plate Av will be `perfectly bnlauced atevery point in its movement, so long as the ways E and-F are equally inclined in respect to a horizontal line. y

1t will also be seen, that very slight power applied to plate or coliar, will produce the movement described.

A return movement of plate A. will be caused by the descent of guide O down the incline E, which will bring guide D. toits former position.

The guards N'Fand' N" may be used, makingthe ways E and F in form of a groove or slot, cir-the guards l may be left olf.

The short parallel ways c* and aF allow a direct movemeunplnte A, for making the impression.

It wilt be'seen sti'd furiiieryoy reference to iig. 1, thattiie extensive reciprocating movement oi' plate A will becaused by si short lateintmovement oi' the connection-,rods or drawbarsGr", nnd, vasthe guides C and D, which aneconstantly at eqn'ipoise, form the fnlcra for leverage, the difference in the extent of movement of plate A and draw-barG will not cause a.` corresponding disadvantage in leverage.

The construction of ink-fountains has been such heretofore, as to preclude the .use af-certain kinds of printing-inks, which are too short, orv-lard-lke, to be taken up by the fountain-roller, or be conducted even by a well-fountain. I therefore make apressure-fouutuin, by which a lgreuluated pressure upon the ink shall keep it iu contact with the fountain-roller, and also so construct the fountain, as to prevent ilooding of the roller, thus insuring a perfect conduct. The inkfountainv is shown in fig. 1'. g

The tank Z is entirely enclosed, except a small aperture for contact of the ink with the fountain-roller. This aperture heilig small, only allowing 'contact of a line ofink, prevents the f oodiug of the roller when 'pressure .is applied to the ink. g Y

' The gauge Z limits the quantity of ink conducted.

Pressure, bythe use of graduated springs or weights, is applied tothe follower W, a weight, Y, and graduated lever'X being represented in the figure for that purpose. This fountain will conduct, perfectly, ink which-heretofore has been applied only by hand. Rei'- erence, for example, may he made to Mathers Sons best wood-cut ink.

The roler-carriage Q is represented in iig. 1. For this carriage, I use yoke shaped rods, with ,coiled springs, (as in my improvement, case F,)`but diliering entirely in arrangement. Instead of making the yokes fast to the body ofthe carriage, projecting also in front of the same, I place the yokes and springs T on the iside of the carriage, and allow each end of the yoke to move back and forth through a portion of thehody of the carriage, the journal'-box,.for the roller, being made fast to one end of the yoke.' The journal-box 1t is left open on theupper side, and the journal is vheld lin place by the guard S. Theples'sure of the hand behind'the yoke and spring T,.wiil force the joumal-boxRfor'- ward, to such anv extent as to allow the removal of the 'rollerfwhen desired.

I am aware that wedges have been used heretofore for increasing or diminishing the force of the impression of a prin other devices, such as set-screws or pins, straight wedges have been used on both sides of a press. But in such presses as require adjustment at both sides, two adjustments have been necessary, which, if not pcrfcctl y equal and accurate, have occasioned the frequentbinding or breaking ofvdraw-bars, the injury of types, orthe injurious strain o f other parts of the press, besides the loss vof time occasioned by making the-two adjustments.

-In the device, as shown in fig.

I 2, I use two wedges, N N, with equal inclines. These wedges I connect by a bar, O, and place the wedges between inclined bearing-faces Land M; said bearing-faces having alike incline, tomatch the faces of the wedges N ,Nh By moving the wedges further. between their counterbearing faces, the impression will be increased, This ting-press, and, that in connection .with

ing of a misplaced sheet.

Remarlcs.

The straight inclines E and F may be varied, to produce tendency of -plate A forward or backward, if desired, ror the ways may be curved instead of being straight. In the use of a very heavy plate, van additional 4supporting-wheel, Rz, may be used, without changing the e'ect ot' the device, as shown in iig. 5.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A reciprocating plate,

bar O, whichk movement and perfectly adj ust both incombin'ation with wheels, rollers, or guides, moving in or upon oppositely-incliued ways, substantially as herein set forth.

2. A pressure ink-fountain, for printing-inks, substantially as herein set forth.

3. The combination of rods and springs T, journalboxes`R, and guards S, substantially as herein.
