I Specification forming part of Letters Patent No. 14,016, dated January 1, 1356; Reissue1 No. 5S I, dated I August v10, 1858.

Figure 1 beingavertical section; Fig. 2, a front elevation; Fig. 3, a detached side view of the toothed wheels on the cylinder and the racks on the sidesof the form-bed,or vthe bed upon -which the types are placed, thus forming one and the bed upon which'tley rest.-

The nature of nay-invention may be understood as follows l First. The employment or use of two-disks, one being annular and the other circular," each so fitted to the other that while'one is revolving one Way (that is, in one direction) theother is moving in a precisely opposite direction. The circular disk is placed within the annular ring in order to eiiect the object of allowing the two disks to rotate each ina contrary direction to the other, this for the purpose of dislcomplete body (for-the time being) of the types;

`tributing the ink, which is to be by these tables conveyed to the rollers which -ink th form of types.

Second. In providing a rotating reci procatingv cylinder and reciprocating form or type bed so arranged that at the proper time it will impinge, and thus give the impression to the form at the proper time, as will be described. Third. I employ a reciprocating form or type bed, which may be placed atany given angle, and thus used with a rotating cylinder so arranged as to rotate and reciprocate its motions by the arrangements to be described, in .Order to drop or pile the printed sheet at the desired place and in the proper time.Y

Fourth. 1 employ a set. of one or more rollers, and imparting to said rollers an oblique vibrating motion over'the disk and plate or annular ring for the purpose of giving an equal distribution of the ink.

, To enable those skilled in the art to make and use my invention, I struction and operation.

will describe its conof the swinging frame.

A A represents a properly-shaped frame to variable motion from one line to the othersof the portionsof the bed, this vcam c in theface of the wheel G peribrming its proper part. The shaft .F has a plain wheel upon its periphery 5 but upon it sside is a grooved cam, which n is to control the movements of the arm I. The grooye is shown at a as presented inthe-y dotted H is a shaft, having an arm, I, on one end. The outer end of this arm works by means of a stud in the cam a within the g'rooved cam G. The shaft H has also the two arms J J attached toit, and the outer arms, J, have a shaft, K, tted in them, said shaft passing through slots b bin the lower end of an upright swinging frame, L, which is hung on a swinging frame, M, placed within the upper ends of uprights attached to the lframe A. To one of the side pieces of the swinging frame L there is attached an upright, d, having a pawl, e, at its upper end.

N represents the type or form bed, which works uponwgiies or ways on the side pieces The form-bed is connected by pitnien o o, one at each side, to the toothed wheel Efa-nd WheelA G, the pitmen being attached to said wheels near 'their peripheries, as clearly shown in Fig. 2.

To each side of the form or type bed N there is attached a rack, P, one of which is permanently iixed, while the second rack, P', is made with slots, so that it may be adjusted 'for the purpose oi' .always insuring full and complete Vgear with the segment, notwithstanding its movement to and from the point of contact or meeting of the face of the type with the sheet of paper upon the face of the cylinder or segment, land the withdrawal from such contact .in the alternate movements which necessarily take place as the press assumes its various positions for Vthe purpose of accomplishing its, various operations. These racks' gearinto n. i ser toothed wheels Q Q, Which are att-ached o ne f, made in it, linl which groove the end of a` lever, S, is fitted. This lever is attached to the frame by a pivot,'y, and the opposite end of the lever is forked and encompasses the shaft of an ink-rellerl, the end of which s adjoining lthe lever Sis fitted in an oblong slotin an upright, h, attached to the frame.

The opposite end 'of the rollerThas its bearing in an'upright, c', attached tothe frame. The v roller T'is 4placed directly in front/of the type or form bed and moves the inking-rollers, one or as many as may be required, these being fitted in the same uprights. U represents a feed-board placed over the upper part cf the cylinder R; and V is a flyboard placed underneath the cylinder.

To the upper part vof the ty'pe or form bed N there is attached a circulardisk, W, having a bevel-wheel, j, attached to its axis on its Y outer end. The plate W is encompassed by an annular disk, X, which has a bevel geared rim, k, on its outer side, in which a pinion, l, gears, said pinion also gearing into the wheel jon the axis ofthe disk W. A rim, m, having ratchet-teeth cut in it, is also .placed 4on the outer lside of the disk X near its periphery.

Tl'ie'cylinder R is provided withngers n, to catch and hold the sheet of paper.` These l'i gers are operated in the usual manner.

Operation: The two racks P ll bear one vagainst the upper edges of the teeth of one wheel Q, andthe other rack again st the other edges of the teeth of the other wheel, so that u no play is allowed between the teeth of thek racks and those'of the wheels. Thisis effected by adjusting the rack P to a propc'r'position.

The sheets of paper to be printed are placed upon the feed-board U, and the form is secured A to thebed N in lany proper way. Motion is given the shaft B and a reciprocating mot-ion -is communicated to the type orform bed N by. the pitmen o'o. When the type or form bed rea ches yits highest point, the lower end of the swinging frame thrown toward the cyl-4 inderby the shaft K, which receives its motion from the shaft H, the shaft H .being operated by the arm I, the end of which works in the groove c in the side of the wheel G. The cylinder R has a' rotating reciprocating motion', 1 Y givendtby the racks? Pfand 'the-'toothed' 'wheels Q Q. The sheets of paper are caught 4kin the usual way by the fingers or grippers n on the'cylinder, andas they a-re carried around vbetween the cylinder andthe form the impression is given. The cylinder then deposits the printed sheets upon the fiy-boardV. J ustbei'ore the type or form bed commences to move upward the shaft K` throws the lower end'of the swinging frame, and conse' v quently the form, olii: from the cylinder, and the pawl e Vacts against the rim m and causes theannular 4disk X to revolve a given dis- `inked by theirs'contact with the disks.

oblique vibratory movement causes the inkto tance. The circular disk W is caus'cdtorotate a corresponding distance 'in an opposite direction by means ot the gearing, (Beej k l.) Thedisks X W are supplied with ink from a fountain ot" common construction, and the rotation of' the disks described serves to distributc it evenly upon said disks. Then one or all of the rollers are thrownin au oblique position, when in contact with'the bed, by the lever S. which is operated by the irregular groovaor mmf-,1in the side of the wheel Q. As the form or type' bedN descends, the two disks pass behind the rollers T, which become The be evenly distributed on the rollers. The form is inked while passing both up and down behind the rollers. By adjusting the rack P as shown the sheets of paper will beproperly presented to the form and to the impression,

which will not be slurred, as all unnecessary play is thus taken up bythe adjustment referred to, such adjustment compelling their movements always to Work in perfect harmony one with the other. Thusall wear or other. in-

accuracy may be at once taken up by the adjustment.

Apress constructed upon the principles here laid down is extremely simple, economical to manufacture, efficient, and rapid in its operation.

v`Wl1at I claim as my invention, and desire "to secure by IIettersPatent, s- A l'. The arrangement and combination of a rotating disk, W, with an annular ring or outside disk, X, the two revolving each in an op posite direction to the other for the purpose of breaking up the ink, so that it shall by such contrary motions become evenly distributed, and thus imparted to the rollers which ink the form of types.

2. I claim-moving the rollers T (one or more being used) for inking theform from the parallel position they necessarily assume l for this purpose, chan gin gto an oblique position,which shall give to thema lateral motion when in contact with the distributing-disks. ot some equivalent, for the purpose specified.

3. I claim the arrangement of a which alternately varies its motion during its reciprocating movemen t-viz., first, traveling under and in contact with a cylinder tongive an impression, then being withdrawn from 'contact with thecy linder and -remainin g with-n ,s "drawn during the return movement to prevent an impression, suchbed reciprocating and at the same time alternating from one of these positions to the other, thus performing two separate and distinct motions, entirely independent of and in a contrary direction to each other, while remaining in gear with the cylinder, whensuch bed shall be used with a cylinder or its equivalent having a part revolution with a reciprocating movement.

4. I claim attaching to the reciprocating form or type bed an adjustible rack, as well as a stationary rack, which two rack-s shall form-bed .play into gear upon a cylinder or segment of in a vertical position, or any given angle from 1 a horizontal position; but I do claim so placing the bed when used with a rotating reciprocating cylinder or segment of a cylinder which shall place or pile the sheets of printed paper upon the fly-board1 as herein set forth v and described.
