DEVICE FOR CONNECTING.PRlNTlNG-PRESSES WITH FOLDING-MACHINES.

SPECIFICATION forming part of I etters Patent No. 355,352, dated January 4, 1887.

Application filed December 22, 1883. Serial No. 115,393. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. STONEMETZ, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Connecting Printug-Presses with FoldingMachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to means for connecting a printing-press with a foldingmaohine, whereby the same connecting mechanism will be applicable to the attachment of a folding-machine to any printing-press irrespective of the position of the heading on the printed sheet as it comes from the press, so that the folded sheet will have its heading on the outside. With most presses the heading V will comein the right position on the folded sheet if the sheet as it comes from the press is passed directly to the first folding-rolls; but with some presses it is necessary to reverse the sheet before folding it, in order to bring the heading on the outside of the folded sheet; and the object of the present invention is to provide means which will permit a folding-ma- I chine to be attached to either style of press sheets of paper as they pass to the folding devices. Fig. 2 is a plan or top view of the devices interposed between the press and fold ing-machine, the position being the same as in Fig. 1. Fig. 3 is a side elevation of part of a press and folder and the sheet-carrying with a pair of rollers, B O, that are arranged in different planes, and one set a little in advance of the other, so as to cause the sheets to pass into the nip of the tapes passing around said rollers. The latter are journaled in suitable brackets located at the upper end of the table A, at or near the side edges thereof. Endless tapes I) and a pass around the rollers B G and travel above the table A, the lower ends of these tapes passing around rollers D and E, located at the receiving end or side of a paper-folding machine. journaled in brackets Ror top extensions of the frame-Work of the folding-machine S, and are driven from the main shaft of the folder, this shaft itself deriving motion from the printing-press Z through the medium of a sprocket wheel and chain, or other connection. I

f are tapes, which pass around roller E and around tension or guide pulleys F, located at the side of the folding-machineopposite the rollers D E. These tapes travel above the folding-rollers O, and serve to properly present the sheets of paper to the same.

N designates a folding or tucking blade, which operates in the customary manner, for pressing the sheets of paper between the rollers O. The table A, with its conveyer-tapes, bridges the space between the folding-machine and printing-press, and rests upon the latter in close proximity to the delivery-wheels J. At the lower end of the table A are located brackets or arms 1?, which are secured to the side edges of said table, as is clearly shown in the drawings. These arms or brackets extend beyond the table, are somewhat curved, and have an eye, 1), as is shown in Fig. 1, or a fork, p, as is illustrated in Fig. 3.

From the upper portion of one side of the These rollers are v folding-machine project parallel brackets R,

IOO

arms of the table A, and constitute the bearings on which said table can be turned when the table is to be removed from operative connection with the press. Furthermore, they receive the journals of the rollers D E, said journals being designated by the letters at e in Figs. 1 and 3.

In Figs. 1 and 2 the brackets or perforated arms I? of the table A are shown as being hung or fitted on the bearings r, in which the inner roller turns, and when in this position the table A extends immediately over the foldingmachine to the printing-press, located on the opposite side of the same, and serves, in connection with its eonveyer-tapes, to carry the printed sheets from the printing-press and present the same to the folding devices in a position the reverse of that they were in when leaving the printing-press. This reversal of the sheets is rendered necessary at times, in

order to bring the heading of the folded paper on the outside thereof, and is effected by passing the sheets coming from the press between the rollers D E, which obviously causes the sheets to travel in an opposite direction from that they followed when descending from the press; or, in other words, the printed sheets that have been conducted to the rollers D E by the two sets of tapes of the tableAare reversed by said rollers and carried in an opposite direction by the tapes arranged above the folding-rollers.

When the style of press in connection with which the folding-machine is to be used does not require the printed sheets to be reversed in order to bring the heading of the paper on the outside thereof, the brackets or arms P of the table A are placed on or attached in the setting up of the machine to the trunnions or bearings 1', in which the outer rollerturns, and when the table A, its appurtenances, and the folding-machine are in this position, as is shown in Fig. 3, the travel of the printed sheets is in a direct line from the printing-press to the position they assume for proper presentation to the folding-knife.

It will be understood that when the reversal of the printed sheet is not required, the folding-machine is placed at a little distance from the press, with the side carrying the rollers D and E toward the press, as shown in Fig. 3, and in setting up the folder the tapes 0 and b are strung around the rollers D and E, :respectively. On the other hand, when the same machine and conveyer is to be-used with a press that requires the reversal of the sheet, the folder is placed nearer to the press and with the side having the rollers D and E away therefrom, and in setting up the machine the upper tapes, 0, are passed around the roller E and the lower ones, 1), around the roller D. Thus the same folder and connecting devices can be set up and used with a press of either style, and the folding-machine, with its sheetconveying attachment, can be manufactured complete at the factory and shipped ready for arate from and independent of the tapes fof the folder, instead of making the latter a continuation of the'former.

In the form of machine illustrated in Fig. 3, the rollers D and E, that drive the three sets of tapes, I), c, and f, are operated by means of a pulley, H, and a belt, 9, which passes around said pulley and another smaller pulley, G, which latter pulley may be fitted on the journals of either one of the rollers D E. This arrangement permits the various tapes to be run in the desired direction without necessitating the running of the pulley H always the same way, it being obvious that by shifting the pulley G from one roller-journal to the other-the proper IDOVGIIIGHU of the tapes is ob tained and the adjacent portions of the tapes b 0 caused to always travel in a downward direction. The rollers D E are geared together by spur-wheels I, as is clearly shown in Fig. 2, in which the position of the three sets of tapes is also fully represented.-

In the construction shown in Fig. 1 I dispense with the band-pulley and use a large driving spur-wheel, H, which meshes into a pinion, G, on thejournal of the roller D. This spur-gearing is more positive in its action than the bandpulleys, but not so cheap as the latter.

It will be understood that the large gear H, as shown in Fig. 1, as well as the gears I, as shown in Fig. 3, are full gears, the same as shown in Fig. 2, and the teeth are only partly shown in the first-named figures for convenience.

I do not in the present case claim, broadly, a sheet-conveying attachment for folding-machines, consisting of a hinged or swinging table or platform having conveyer-tapes, as this forms the subject-matter of an application for patent heretofore filed byme on the 14th day of March, 1883.

What I do claim as new, however, and de sire to secure by Letters Patent, is-

1. The combination of a paper-folding ma chine having brackets with two sets of fixed trunnions or fixed hollow roller-bearings with a shiftable conveyer table or platform adapted to rock or turn on said trunions, the conveyertapes and their guide-rollers, and the folding devices, substantially as herein set forth.

2. The combination of a paper-folding machine having rollers D and E, the shiftable table A, having top rollers, B O, and endless tapes I) a, passing, respectively, around the rollers B E and D O, and the endless tapes f, separate from the tapes of the eonveyer atno I tachment, passing around the roller E and guide pulleys or spools on the folding-machine, substantially as herein set forth.

3. The combination of theshiftable table A, having pulleys B O, conveyer-tapes b c, and apertured or forked brackets or arms, with a folding-machine having rollers D andE, and two separate bearings for the brackets of the shiftable table concentric with the rollers D and E, substantially as herein set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
