Specification of Letters Patent.

Application filed January 25,1904. Serial no. 190,630.

To all whom it may concern/.-

Be it known that I, WALTER Soorr, a citizen'of the United States of America, ands resident of Plainfield, Union county, New Jersey, have invented certain new and useful Improvements in Paper Transmitting and Controlling Devices, of which the following is a specification.

M invention relates to printing or other mac es, and has more particular reference to means for transmitting and controlling sheets.

The object of my invention is to prevent the smutting of the printed sheet while passing through the machine and to deliver the said sheet with-the printed side up.

In transferring a sheet from the im ression or other cylinder to the transfer or ot er cylinder the parts are generally so arranged that the printed sheet travels around the said transfer-cylinder with the printed side adj acent to or in contact with the said cylinder.

In this way the sheet frequently smudges. To prevent this, I employ a circumferential and stationary guide or guides adjacent to the cylinder, against which guide the sheet is blown by air-pressure from within the cylinder around which it travels and is, further more, in the present instance delivered with the printed side up. This delivery operation is effected by having the guide extend only part of the way around the cylinder or by cutting away a portion of the said guide at the delivery-point A delivery-table or other means is placed adjacent to the delivery-point, so that as the sheet comes adjacent to the same the air-pressure will blow the sheet outward and downward, thus delivering the sheet with the rinted side up. The cylinder is, as is usual provided with gri pers' or with other means for carrying t e sheet around with it. These grippers take the sheet as it passes from one cylinder to the other, so that it will travel around with the said cylinder, the air-pressure blowin the sheet out of contact with the said cylmder and up-gagainstthe guide,which confines it as it travels around the said cylinder. When the delivery-point is reached, the grippers release the sheet and the air blows it downward, with the printed side up, on the delivery-table or other means of a similar nature.

in the present application I have shown my invention adapted to be used in connection witll a bed,andcylinder press; but it is my invention.

obvious that it may be applied to other forms of resses aswell. Q

n the drawings, Figure 1 is a side elevation of parts of a printing-machineembodying Fig. 2 is a detail View in section of the transfer-c linder. Fig. 3 is an. end view of a press 100 ng in the direction of the arrow in Fig. 1. Fig. 4 is a diagrammatic view showing a modification of my invention. 1

Similar characters of reference indicate corresponding parts in the different views.

1 indicates a feed-table, while 2 is the impression-cylinder, and 3 the reciprocating ed, all of any usual or suitable construction. Placed adjacent to the impression-cylinder is in this case a delivery-cylinder 4, provided with the grippers 5 of any suitable construction and constructed with a plurality of apertures 6 for the emission of air under pressure, acting against substantiall the entire surface of the sheet, so as to reep the body thereof out of contact with the c linder. These apertures, While they coul extend all the we around the cylinder, are in this case place only at a point immediately in the rear of-the gri )pers and extend for a distance equal to the ength of the sheet to be acted u on. The apertures 6 are preferabl dispose at ariangle to the radius of the cy inder 4, as shown in the drawings.

Adjacent to the cylinder 4 there is located a circumferential and stationary guide 7, extending in this instance only part of the way around the c linder 4.namely, from the pointwhere t e grippers 5 of the cylinder 4 seize the sheet and to a point 8, located some distance away from the point at which the grippers 5 release the sheetso that the said sheet is free to move outward and downward by reason of the air-pressure issuing from the apertures in the cylinder 4. 9 is the deliverytable, located below the cylinder 4.

The air-pressure issuing from the cylinder 4 may be obtained in any suitable way and can, as shown in the drawings, be received from a source of su ply, as the blower 10, suitably connected wit the inside of the cylinder 4-. by meansof the pipe 11.

The sheet passes from the 'feed board around the im ression-cylinder and receives an impression etween the said impressioncylinder and the bed, after which it is carried up to the delivery-cylinder 4, where it is seized by the grippers 5, thereby transferring the sheet from one cylinder to the other. the cylinder at rotates, the grippers :3 will carry the sheet around vrith them: but the sheet will be held away and out of contact with the said cylinder 4 by reason of the air pressure issuing, from the said cylinder 4, which will blow the sheet up against the slationary and circinnferential guide.

the grippers to the position shown. in Fig. 1, Where t the air-pressure and downward upon the delivery-oible below. In this Way it Will be observed that although the printed side of the sheet is udiacent to tl e cylinder ll it is held out of contact with the same by reason of the airprcssure, and yet travels around with the said cylinder by means of the grippers 5 or by other sheetcarrying means. It will also be observed that when the sheet arrives at the proper point the grippers release the sheet and the sheet is delivered niiththe printed side up.

The cylinder 4 will conveniently be provided with a high surface. as l 2, at the point i where thegrippers 5 seize the sheet, or the main portion. of the cylinder 4 will be turned down exec .t at the point where the grippers locate i. This is done to give the sheet sutiirient space to be free iron: contact with the cylinder.

The confining-guide 7 can be made as one or more members and can, further, as shown in Fig. 2, he made adjustable, so to provide or ditlcrent lengths of sheets. in the said Fig.2,13 indicates a telescoping portion on the guide whereby its length "an he increased or decreased, the screws 14 being: utilized to properly secure it in position after it has been adjusted.

The cylinder 4, as previously pointed out, may he a transfer or other cylinder. in Fig. 4 i have shown my invention applied to a twocolor press, in which 15 indicates the lirst plate-cylinder, 16 the first inipression-eylinden 17 a. transfer-cylinder similar to the cyiindex. 4, 155 the second iinpression-cylinder, 19 the second plate-cylinder, and 20 a delivery-cylinder similar to cylinder 21 is e. delivery-table or other delivery means. The
