PERFORATTNG AND CREASING ATTACHMENT FOR PRlNTlNG-PRESSE? Specificationbf Letters Patent.

Patented May 28, 1907.

Application filed July 6, 1905. Serial No. 268,404.

To all whom it may concern: 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 Wisconsin, have invented cer tain new and useful Improvements in Perforating and Creasing Attaclnnents for Printing-Presses; and I do hereby declare that the following is a full, clear, and exact f description thereof.

My invention refers to perforating and creasing attachments for printing presses, (provide a device of the character Inentione which may be readily attached to a cylinder press without dis arranging the mechanism thereof, another object being to so locate said attachment that it will catch the paper as it is delivered from the cylinder of the press, after having been printed, and draw said paper between a pair of perforating or creasing rollsfrom which it Wlll be delivered by the usual fingers to the table, and thus the aper is printed and perforated or creased g ordinarily required to print and discharge said papers, said invention consisting in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings: Figure 1, represents a fragment of a cylinder printing-press in elvation from the gear side of same and illustrates in connection with the press ,Fig. 2, a transverse section of the same; Fig. 3, a cross-section on line 33 of Fig. 2; F ig. 4, a detail view of frag ments of the creasing-disks on an enlarged scale; Fig. 5, an elevation of the same; Fig. 6, a detail section of the paper after being creased; Fig, 7, a side elevation of a portion ':of the frame of the attachment, illustrating a perforating disk and therewith; Fig. 8, a transverse section of the same on line 8-8 of Fig. 7. Fig. 9, an enlarged detail of a portion of the perforating-disk and bed therefor, and FigslO and 11 another form of perforating disk.

My invention, as embodied in the attachment illustrated,- varies with relation to what is set forth in my Patent No. 796,450,

parts cooperative granted August 8, 1905), for improvements in creasing or indenting presentmeans, as previously stated, perforates or creases tie paper just after it leaves the cylinder of a printingpress, and

uring the time boxes a of devices, in that my 1 dispenses I indicates a portion of a cylinder-press frame, B the cylinder shaft and C the printing- Between the arms, D of said rarne is secured a rod E on which is mounted the usual strippers F, the arms also serving as bearings for the paper-discharge rolls G that are driven by a gear-wheel H through an intermediate gear-wheel I meshing with the driving-gear J of the printing-cylinder. The gear-wheel I is mounted u on a stud K projecting from the arm D of t 1e frame, and the gear-wheel H istoothed so as to form another gear face H of larger diameter through which motion is transmitted to the perforating or creasing attachment.

The brackets L for the support of the erforating or creasing mechanism are for ed, and also provided with feet M for attachment to the frame A, and with braces N, at their upper ends which are bolted to the arms 1) of said frame. An upper shaft 0 and a lower shaft P, which carry the several percylinder.

forating or creasing devices, have their bearings in adjustable boxes o b, respectively fitted between the forks of the brackets L, and secured to the shaft 0 at one end is a gearwheel Q which meshes with and is driven by the gear-face H of gear-wheel H. The boxes I) of the shaft P rest upon filler-blocks c interposed between said boxes and the base of the bracket L. Below the filler-blocks and resting in recesses in the base of bracket .J, are springs (1 having tension-adjustment, by a set-bolt e. The shaft 0 is held in position by coil-springs f interposed between the said shaft and the boxes I), in opposition to set-bolts 9 located in caps h secured to the top of forks of the bracket L.

The shaft P is driven at the same speed as the shaft 0, through gears 71, j, respectively lo cated upon the ends of the said shafts, as illustrated in. Fig. 3.

As illustrated in Figs. 1, 2, and 3 the shaft 0 of the attachment is equipped with two gangs or sets of creasing disks S. Each gang is mounted upona thimble T having longitudinal adjustment upon the shaft, and the thimble is held against independent rotation by a. key K fitting into recesses in the thimble and into a corresponding key-way K in said shaft. The key is confined within the thimble by u disk with a spacing-r1ng U (having an annular groove until I 15, so that the 'filler block 0 being the desired number are in place. They are then clamped by a s anner V which is threaded upon said thimb e. The lower shaft P is similarly provided with corresponding sets of disks which break joints with the upper sets disks of the lower shaft mesh with the grooves 0 of the upper sets ofdisks and vice versa. While Ihave described the thim ble T and grooved spacingrings U equipped with creasing-disks, it is obvious that for the latter 1 ma substitute elongated disks W, having elongated perforating teeth shown in Figs. 4 and .5, as in practice it has been found that where an elongated perforation is desired, it can be obtained by combining the perforating-disk with the grooved ring, or the same result may be obtained by interposing the perforating-disk between shear-disks, as illustrated in Figs; 10 and 11.

As shown in Figs. 7, 8 and'9 the machine is arranged for perforating round holes, the removed and a set of boxes p (one of which is shown), for an idle wheel, the cylindrical bed Z of shaft X substituted, the springs (3 serving to force said shaft together with the smoothing roller Y, upward and thus causing the latter to impinge against a cylindrical bed Z, the object of which is described hereinafter. The erforating -.wheel A is provided with a eather g which rests in the keyavay K of shaft 0' upon which said wheel is mounted and secured. longitudinally thereof by a setscrew 7 The wheel A order to produce a clean out round perforations with this soft metal is secured to a shell C, this bed being preferably molded to the shell and heldthereon by.

annular dove-tailed shoulders intermediate of the ends thereof which are also dove-tailed at their inner edges. The shell 0 is secured to. the shaft P by set-screws t which impinge against keys fitted in the key-Way of said shaft similarly to those previously described.

he smoothing roller V is adjusted in line with the perforating wheel and as the latter revolves each tooth or pin embeds itself into the soft metal bed Z, which supports the paper while being perforated, and will thus produce a clean cut. The holes made in said metal bed are ironed out by the smoothing roller until the bed at this pointhas become worn. The bed may then be adjusted longitudinally of its shaft to bring a fresh surface the thimble T and tors-Patent 1s:

Having thus described my invention what Lclaim as new and desire to secure by Let- 1. The combination with a cylindrical printing-press, of a detachable perforating or creasing machine consisting of a bracket secured to the frame .of the press, a pair of shafts mounted in said bracket at the discharge side of the printing-cylinder, perforating or creasing disks secured to the said shafts, and a driving means connecting one of the shafts with the driver of said printingcylinder.

2. The combination with a cylindrical printing press, of a detachable perforating or creasing machine consisting of a bracket secured to the cry end of same, a pair of perforating or creasing disks mounted on shafts, adjustable boxes for the shafts supported in said bracket, and a driving-gear mounted upon one of said' shafts in mesh with the drivinggear of the paper-discharge roller of the press.

The combination with a cylindrical printing press, of a detachable perforating. or creasing machine consisting of a bracket secured to the frame of the press at the delivery end of same, upper and lower shafts ad.- justably mounted in said bracket, meshed gears on the shafts at one end thereof, perforating or creasing disks adju'stably secure each of said shafts, a driving-gear secured the upper shaft ininesh with the driving.

press, and intermediategears interposed between the last named gear and the printingcylinder driving-gear.

4. Ina perforating mechanism, a wheel provided with a series of radial pins, a pliable metallic cylindrical-bed inthe path of said pins, and a smoothing-roller in opposition to said bed. I I

5. In a perforatin mechanism, a wheelhaving a series of ra ial pins, a drive shaft for the wheel, a soft metallic cylindrical bed in opposition to the pins, a shell for said bed and a shaft for the shell, means for adjusting said shell longitudinally of the shaft, and a smoothing-roller in opposition to the aforesaid bed.

In testimonythat 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 G. RAZALL.
