CREASING OR INDENTING DEVICE.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed October 13, 1903. Serial No. 176,892.

To all whom, it may concern: 1

Be it known that I, HENRY G. RAZALL, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of WVisconsin, haveinvented certain new and useful Improvements in Creasing or Indenting Devices; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to devices for creasing, indenting, or otherwise breaking the surface of paper; and it consists in certain peculiarities of construction and combination of parts constituting an attachment to a cylinder printing-press, all as will be fully set forth hereinafter in connection with the accompanying drawings and subsequently claimed.

In the said drawings, Figure 1 is an end elevation of part of a printing-press with my device attached thereto Fig. 2 is a sectional view of said parts. Fig. 3 is a view in front elevation of said parts. Figs. 4:, 5, and 6 are detail views illustrating different forms of the creasing or indenting disks used with my device.

My invention as embodied in the devices illustrated affords a means for creasing or indenting sheets of paper immediately after the same are printed and before they leave the press, so that the first sheet is being creased or indented while the second sheet is being printed and said second sheet is being creased or indented while the third sheet is being printed, and so on continuously, thereby effecting a great saving in time and expense.

Referring by numerals to the drawings, 1 1 designate portions of the frame of a cylinder printing-press, 2 the feed-table, and 3 the revolving cylinder, all of ordinary construction, and hence I have not deemed it neces sary to show the cylinder-fingers nor any of the details of said parts nor the flat bed-plate and means for reciprocating the same under the revolving cylinder.

4 designates a rod supported by the frame of the press above the cylinder 3 and having feed-rollers 5 bearing upon the said cylinder, there being also a pulley 6 on said rod 4:, from which a driving cord or belt 7 runs toa like pulley 8 on a hub on the end of a shaft 9, hereinafter described.

10 10 designate brackets extending from the side portions of the frame of the press and provided with lugs 11 and with transverse bores for the reception of the ends of the rod i 12. 13 13 are bell-cranks supported on and fast to said rod 12, the upper arms of said bell-cranks carrying the adjusting-screws 14, whose inner ends bear against the bracketlugs 11 and which after adjustment are set by the nuts 15 15, as shown. The lower ends of the bell-cranks 13 terminate in hubs which receive the ends of the shaft 9, which is further supported by the central hanger 16, whose upper end is formed into a split ring with a screw, whereby it is clamped to the described rod 12.

The creasing or indenting disks are mounted on the shaft 9,- as shown at 17 17, and may consist of any desired number of said disks, according to the width of the creased or indented strip desired, there being preferably collars 18 18 with set-screws on each side of a disk or group of disks, so that the same may be moved to the desired location on the shaft 9 and there made fast. In Fig. 4 I show a portion of one of these disks for making short indentations, while in Fig. 5 I show part of a perforating-disk and in Fig. 6 a disk for making a continuous crease.

The operation of my device will be readily understood from its construction, taken in connection with the accompanying drawings. Sheets of the desired size are fed from the table 2 to the cylinder3, whence they are carried down to the form on the bed-plate and printed, and then the fingers of the cylinder draw them up between the cylinder 3 and the disks 17 and they are creased or indented while still on the cylinder and before they are discharged onto the fly, thereby entirely obviating the necessity of running the printed sheet through a separate machine or machinesfor the formation of creased or indented lines, as is now customary.

While I have illustrated the preferred construction of my attachment, it will be understood that mechanical changes in the detailed construction and arrangement of the parts may be made within the scope of the claims without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cylinder printing-press, the combination with the frame thereof and a revolving cylinder, of a horizontal rod supported above said cylinder by the frame of the press, a series of feed-rollers on said rod bearing upon the said cylinder, and a pulley upon said rod beyond the line of said cylinder; brackets extending from the side portions of the press frame, and provided with transverse bores; a

transverse rod, supported in the bores of said brackets; hanger-arms rigidly secured to said rod, and terminating in hubs; a revoluble shaft journaled in said hubs; a pulley on one end of said shaft; a driving cord or belt running from said pulley to the pulley on the feed-roller rod; and a series of creasing or inthe said cylinder, and a pulley upon said rod beyond the line of said cylinder; brackets extending from the side portions of the pressframe, and provided with transverse bores, and with upward-projecting lugs; a transverse rod supported in the bores of said brackets;

bell-cranks on and fast to said rod, the upper arms of said bell-cranks carrying adjustingscrews whose inner ends bear against said bracket-lugs, and the lower arms of which bell-cranks terminate in hubs; a revoluble shaft journaled in said hubs; a pulley on one end of said shaft; a driving cord or belt running from said pulley to the pulley on the feed-roller rod; and a series of creasing orindenting disks carried by the said revoluble shaft, and adapted to bear against the said re- .volving cylinder.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in

the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.

HENRY Gr. RAZALL.
