JOHN BROOKS, OF PLAIN FIELD, NEW JERSEY, ASSIGN OR, BY MESNE ASSIGN- MENTS, TO THE POTTER PRINTING PRESS COMPANY, OF SAME PLACE.

PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 539,377, dated May 14, 1895 Original application filed August 5, 1889, Serial No. 319,795. Divided and this application filed April 19, 1890- Serial No. 348,716- (No model.)

To all whom it may concern:

Be it known that I, JOHN BROOKS, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey,

have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification.

My invention relates to cylinder presses having an auxiliary feed cylinder or automatic to sheet conductor to which the paper is fed antomatically by a web cutting mechanism as heretofore shown and set forth in a prior application filed by me August 5, 1889, Serial No. 319,7 95, of which this is a division so far 1 5 as the combination of an automatic-sheet conductor, and an oppositely extending feed-table with an impression cylinder common to both is concerned.

The object of my invention is to combine :0 with a press, having an automatic sheet conductor, a feed table surmounting the delivering end of the machine, whereby instead of using the web cutting mechanism the sheets may be fed separately by hand in the usual manner from the feed table, and the latter surmounting the delivering mechanism will occupy as little space as possible and promote convenience in the press room.

My invention consists in combining with the 30. impression cylinder and its auxiliary feed cylinder by which the sheets are supplied automatically from the Web cutting mechanism, a feed table tangent to the impression cylinder at an opposite side thereof from the direction from which the sheets are fed from the cutting mechanism.

Referring to the accompanying drawing, a sin gle-cylinder press isillustrated, of which A is the impression cylinder, B a skeleton 4o feed cylinder or sheet conductor, and O a delivery cylinder.

D, is the type bed, and the mechanism for driving the same in proper relation to the impression cylinder A, is of the character corresponding to that referred to fully in my Letters Patent No. 413,491, issued October 22,,

1889. The means of driving the web cutting mechanism indicated at E, is also fully described in said patent and these elements will not therefore require specific description here.

The sheets follow the course indicated by arrows, and the grippers a, b, c, of the several cylinders may be operated by any suitable mechanism so as to transfer the head of the sheet from one cylinder to another at the proper time, such as that mechanism described in Letters Patent No. 433,716, granted to me August 5, 1890.

The construction of the skeleton feed cylinder B in a series of flanges having intervals between them lengthwise of the cylinder, and the arrangement of the conveying belts d and distending arms e, in conjunction therewith, also corresponding to those described in said application.

The feed gage for the feed table consists of a series of arms f, extended between the flanges composing the feed cylinder; the gage shaft g, receiving its automatic motion to lift the gage and clear the sheets when the grippers b arrive in position to seize said sheets in the usual manner. Such automatic motion may be imparted to the shaft g, throughthe rock arm g, from any suitable part of the machine. V

F, indicates the flier for delivering the sheets which are conveyed thereto from the delivering cylinder by suitable conveying belts n The flier is also operated from any suitable part of the machine through the rock arm 4..

Having now identified the well known ele ments assembled in the accompanying illustration, I will describe the feature of novelty, Y which consistsin'combinin g with the feed cylinder B, above the impression cylinder A, a feed table H, tangential to the impression cylinder A at a point corresponding to the point of contact of the feed cylinder therewith. The feed table H, is thereby brought adjacent the go delivering mechanism 0, F, for the sheets, lying in an opposite direction with reference to the impression cylinderA from that occupied by the automatic feed mechanism E, B. The

feed gage f, occupies a position in the circle of 5 the impression cylinder A, corresponding to the point of contact between the two cylinders A, B, where the grippers a, b transfer the head of the sheet when the automatic feed E, cl, is used, and the feed gagef, has a slight lifting movement so as not to interfere with the passage of the shaft of the grippers a.

In operation, the web is, is fed to the cutting mechanism E, from a roll placed in any suitable position. The paper theretlrom follows the course of the arrow upon the conveying belts cl, and after being cut the sheets are seized by the grippers a. The feed gagef, is raised out of position being inoperative when the automatic feed is used. The sheets are transferred from the cylinder B to the cylinder A, by the action of the grippers a, b, and J- thence passed in the direction indicated by arrows, into printing contact with the form bed D, being again transferred from the cylinder A, to C, by the action of the grippers b, y c; thence to .the flier. When "the feed table is used thefeed cylinder '13, and cutting mechanism E, are thrown out of gear with theI press, and the feed gage f, brought into posi tion and operation. The separate sheets E upon the feed table are supplied 'bythe'op-; erator against the feed gage in the usual mani ner, being seized by thegrippers b, following a similar course of printing as above de- 1 scribed.

In combining ahandfeed with an automatic 1 feed, the constructions heretofore adopted} have embodied afeedtable located abovet'he automatic cutting mechanism E and feeding;

mechanism or sheet conductor B, which "increases the height at which the operator stands when supplying the sheets to the feedta'ble, and requires greater amount of verticalsp'ace in the press room as well as inconvenience in handlingthepaper. Thehereinini'provedarrangenient of the feed table H in juxtaposition to the delivering mechanismC, F, promotes convenitnce in handling the paper, which uhen composed of separate sheets is done entirely at the one end of the press; the printed sheets being taken also therefrom. 1 Access for supplyingand'removing'the paper; is thus had at a single portion ofthemac'hinefl the roll of paper from which the webis supplied to the cuttingmechanism E,when used, occupying an independent space at the opposite end of the machine not interfering in any i way with the convenience of the operator at the feed table.

Another important advantage consists in rendering the automatic cutting mechanism E and feeding mechanism or sheetconductor B, accessible for adjustment or repairing or for arranging the paper in starting the press, when ,a feed table is also-em ployed in the construction of the press.

Having thus fully described my invention, what Iclaim, and desire to secure by Letters Patent, is-

1. The combination in a cylinder printing :press having an auxiliary feed cylinder above the impression cylinder for automatically feeding the paper, of a feed table tangent to the impression cylinder at a point thereof corresponding to the point of contact of the feed cylinder therewith.

2. In a printing 'press,the combination with the'impressioncylinder, afeed cylinder above the same, and an automatic cutting mechanism for supplying the sheets .to the feed cylinder, of 'a'feed table extending directly to the surface of the impression cylinderfrom an opposite sidethereof to that occupied by the said automatic cutting and feeding mechanism.

3. The combination in a printing machine of an impression cylinder, 'a skeleton auxil- Tiaryfeed cylinder above the same, to which the'sheetsof paper maybeautomatically sup- "plied, of'a feed table tangent to the impressioncylinder at the point of contact of the feed cylinder therewith and a feed gage opposite thefeed table, within the circle of the skeleton feed cylinder.

4. The combination, in a printing press, of an impression cylinder, a sheet conductor leading to the same, an automatic cutting mechanism forsupplying sheets to the sheet conductor, a feed table extending directly to 'the surface of the impression cylinder from an opposite side thereof to that occupied by said automatic cutting mechanismand sheet conductor, substantially as described.
