Application filed February 17, 18538.` Serial No. 264,409. (No model.) p

.To a/ZZ whom it may concern: Beit known that I, MAJORROMEYN JEWELL,

of Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Roller Copying-Presses, of which the following is a specification.

The present invention relates to improvements in that class of roller copying-presses in which the moistening of the paper is automatically effected by a damping-roll, and the paper thereafter conducted between pressure-rolls, as represented, for example, in Letters Patent of the United States granted to Lash, Nos. 333,312'and 354,794, on which the present invention is an improvement, and is designed to overcome the various difficulties incident to the constructions heretofore in vogue. 1

A The improvements relate more particularly to the construction of the frame in such manner as to permit a convenient and speedy removal and insertion of the various rolls; to admit of the pressure on the copying-rolls being nicely adjusted and 0f the rolls being readily relieved from pressure Without destroying their adjustment; to provide convenient means for dividing the paper into suitable lengths or sheets after the copying operation, and to facilitate .the introduction of the paper in vthe iirst instance between the rolls.

In the accompanying drawings, Figure l represents a longitudinal vertical section through my machine and its sustaining cabview showing a portion of one side of the water-tank and the pivoted roller-bearing therein.

Referring to the drawings, A represents the press proper; B, the knife or shearing device on one end thereof, and C the case or cabinet upon which the press is mounted.

The frame of the press consists, essentially,

Vof two vertical side plates a, placed at a suitable distance apart and rigidly connected by cross-rods a or equivalent cross-connections, which will hold them iirmly in their proper relations. On their inner faces the side plates a are provided with `flanges c, which support the ends of a removable pan or tank d, intended to hold the water for dampening the paper. The side plates are also provided with open bearings e to receive the ends or end journals of a cross-roll f, on which is wound a long sheet or web of copying-paper g. The paper passes from the roll downward through the water in the vat and beneath the horizontal roll 71. therein, this roll being supported in a manner which will be presently described. From the roll h it ascends between a squeezing or drying roll t', and a pressure or copying roll j, their joint effect being to remove the surplus moisture from the paper and leave it inV the proper condi-4 The paper is cona greater or less extent previous to the copybe perceived that the frame-plate is provided with a vertical slot a', extending from the upper edge downward, and with two slots a? and a3, opening laterally from opposite sides of the first-named slot. Each slot a2 terminates at its outer end in a bottom seat a4, adapted to receive the journal of the roll Z, which is inserted by dropping it through the slot c and then passing it through the slots a2 to its place.

AThe bearing blocks t" of the roll 'L' are j dropped through the slot a and shoved lat- 4 in dotted lines in Fig. l, at will.

erally through the slots a3 to their'places. In order that these bearings i" may be adjusted horizontally to regulate the pressure ofV the roll z', adjusting-bolts 3 are tapped through ears 4 en the frame and arranged to act against the bearings i. Check-nuts 5 are applied to these bolts to prevent them from working out of adjustment.

The boxes or bearings j of the lower pressure-roll j are elongated vertically and the slot d carried below the lateral slots, so that when the bearing is dropped to its place in the slot d it will receive, as shown in Fig. 3, a iirm support on both sides.

The bearings 7s of the upper pressure-roll k are seated and slide vertically in the upper ends Yof the slots d', and are supported by spiral springs 7a2, encircling spindles k3, which are extended upward from the lower bearings j loosely into a hole in the upper bearings 7a.-

The downward pressure upon the roll 7c is secured by means of a bail m', having eccentric ends m, which act on the bearings 7.3. The bail is provided at its ends with journals m2, seated in the supporting-arms mi, which are in turn connected to the frame at one end by pivots mtand at the opposite end by bolts m5, provided with adjusting-nuts m6. By means of these nuts the arms ymE may be adjusted with great nicety to secure the exact pressure required upon the copying-roll 7o. By throwing the bail backward its eccentrics are caused to relieve the roll 7c from the pressure to prevent it from being fiat-tened on its side when it remains for a long time in an inactive position, and also to admit of the roll rising in order that a sheet may be withdrawn at any time, when copied, to any point in its length.

The adjusting-bolts m5 are connected at their lowerends to the frame by pivots m7, and the ends of the arms m3, through which they pass, are forked, so that the bolts may be thrown downward out of action, as shown This action, without destroying the adjustment of the nuts, releases the arms m3, so that they may be thrown upward in order to permit the removal of the various roll-bearings through the slot a.

Heretofore it has been somewhat difficult to pass the copying-paper beneath the roll h in preparing the machine for action. To avoid this difficulty, I now mount the roll h in bearings which will admit of its rising freely, so that the 'fingers of the operator may pass the paper thereunder. Irecommend for this end the mounting of the roll, as shown in Fig. 5, with bearing-arms 7L connected at their upper ends to the sides of the pan or vat by pivots 7a2. A spring h3, of the form shown or other suitable form, is connected to the pan and bears on the larms h to hold them down in position. The use of these springs is not, however, essential, as the weight of the roller will ordinarily keep it down in place. The arms may, if desired, be pivoted to the side plates of the frame instead of to the pan, and they may be modified in form and arrangement at will, provided only they permit the roll 7L to rise and fall freely.

As this machine is intended to operate mainly on a long web of copying-paper which is to be subdivided after becoming dry,Ipro vide for the machine a special cabinet, such as shown in Fig. 2, having its top adapted to sustain the machine, and having at the delivery end of the machine an opening c', through which the paper may descend to the interior. To facilitate the removal of the paper, I recommend the provision of a second slot or opening cZ at the opposite side of the cabinet. The end of the sheet being passed upward through this opening and retained at the outside enables the operator to quickly withdraw it, and this regardless of the quantity which may be contained within the cabinet.

In order that the web containing the copies may be conveniently divided into sections or sheets of the ordinary length, I mount on the machine, at one end, the knife or shears B before referred to, and provide at the top of the machine a horizontal skeleton plate a5, to receive the sheets as they are cut from the web. The shears' may be of any suitable construction, but inthe form shown they consist of a cross-bar b, provided-with a fixed blade b', and of a vertical swinging bar b2, provided with a vertical blade b3. The upper bar b2 is provided at one end with a horizontal journal b5, turning on a pivot b, sustained by ears on the lower plate. A spiral spring 117, suitably inclosed for the purposes of protection, acts laterally against the blade b2, holding it as it descends with a yielding'pressure against the edge of the plate b', this action insuring a clean sepa- IOO IIO

ration of the paper whether moist or dry. The

ward the bar is released at one end and may be then lifted and disengaged at the other. Vhen the knife is located upon the press in the position shown, the web of paper may be conveniently drawn upward through the opening c2 through the cutter and supported upon the plate a5. The plate and sides of the press serve as guides for cutting the paper to the proper length, for supporting it after being cut, and for insuring the cutting action at right angles to its edges.

It is to be noted that in my machine the lower roll h is merely a guide to compel the passage of the paper through the water, and that it is not a damping-roll in the sense in which that term is used in the art.

Having thus described my invention, what I claim is- Y l. In a roller copying-press, and in combination with the pressure-roll, the eccentrics for depressing the same, the arms which sustain the eccentrics, and the screws for adjusting the arms, whereby the degree of pressure may be accurately adjusted and the roll relieved of or subjected to pressure at will without disturbance of the adjusting-screws.

2. In a roller copying-press, and in combination with the pressure-roll, the bail with its eccentrics, the bail-supporting arms pivoted to the frame, and the adjusting nuts and bolts adapted to swing into and out of engagement with the arms, as described.

3. In a roller copying-press, the main frame having its side plates provided each with the slot extending downward therein from the upper edge and with roll-adjusting screws in the outer walls of the slots, in combination with the (zo-operating pressure-rolls, the roll boxes or bearings adapted for insertion and removal successively through the open ends of the slots, and pressure devices hinged to the frame and overlying the slots, whereby the ready removal and insertion ot' the rolls is permitted Without disturbing the adjustment of the screws.

It. In a roller copying-press, the combination of the bed or table a5, the copying-rolls 7c and j at one end of said bed, the stationary transverse bar b at the opposite end of the bed, and the hinged knife-bar b2, arranged to co-operate with the bar b, whereby the table is rendered available to support and guide the paper passing between the copying-rolls,

and also rendered available to vsupport and guide and gage the length of the sections cut from the end of the copy-sheet.

5. In combination with the roller copyingpress having the delivery devices at one end and the knife at the other, the cabinet provided with two openings `for the passage of the paper.

6. The sustaining-cabinet fora roller copying-press having in its top near opposite ends two openings for the passage of the paper, whereby it is adapted to admit, hold, and deliver a long web of paper without entangling the same.

7. In a roller copying-press, and in combination with the water-pan, a roller H, mounted in said pan independent of the wringing and copying rolls and movable freely in an upward direction from its operative position, whereby the operator is enabled` to lift said roll to pass the copying-paper thereunder.

8. In a roller copying-press, and in combination with the water-pan, the rollerh, its pi-voted sustaining-arms, and the springs acting thereon.

9. In a roller copying-press, the combination of a support for a rollof paper, a waterpan containing a roll beneath which the paper is carried through the pan, two elevated pressure copying-rolls, and a squeezing or wringing roll acting forcibly against one of the copying-rolls and independent of the roll in the pan.

10. In a roller copying-press, a water-pan and means for `guiding the web of paper through the 4Water therein, in combination with two rolls vl and j, independent of the damping devices, to squeeze the moisture from thepaper, and a third roll 7o, bearing upon the roll j, to effect the copying action.

In testimony whereof I hereunto set my hand,this 30th day of December, 1887,in the presence of two attesting witnesses.
