R. M. DAVIDSON. PERFORMING AMEGHANISM.
A1PLICVAIION FILED JAN. 29, 1908.
WITNESSES: INVENTOR @Mmmm BY vide, in a RoDnRieK M'. DAvrDsoN OF ELMIRA, NEW YORK.
PERFQRATING MEGHANISM.
To all whom it may concern:
Be it known that I, RODERICK M. DAVID- SON, a citizen of the United States, residing at Elmira, in the county of Cheniung and State of New York, have invented certain new and useful Improvements in Perforating Mechanisms, of which lthe following is a specification. x
This invention relates to improvements in mechanisms for forming lines of perforations in traveling webser sheets of paper.
One object of my improvements is to promechanism of this character, a rotating cylinder carrying a radially reciprocatin perforating blade so operated as to be with rawn below the surface of the cylinder immediately after the paper has been perforated, thereby avoiding the necessity of employing withdrawing rolls to draw the paper from the perforator teeth and the oonsequent tendency to-tear the paper at the perforations whilejpassing through the machine.
A further object is to rovide means for setting the perforating glade at different points around the cylinder to locate the perforations Where required on thepaper; and to )rovide the cylinder with means for attac ing more than one perforating blade, independently adjustable, whereby several lines of perforations at variable distances apart may be produced for each revolution of the one cylinder.
' Iattain my objects by constructing and arranging the parts of the perforating mechanism in the manner illustratedin the accompanying drawings, in whichh Fgure 1 represents a front elevation of the perforating mechanism, in so far as my improvenients are concerned; Fig. 2, a plan view of the p'erforating cylinder showing one of the adjustable cylinder segments containing the perforating blade; Fig. 3, a transverse'section on the line a-a in F ig. 1 and Figs. 4 and 5, similar sections, respectively, on the lines b-b and c-c, in Fig. 2.
Like numerals designate like parts in the several views.
l The' two cylinders, 2 and 3, which carry the several parts of the perforating mechan-.l
ism, are mounted to rotate between thej' Specification of Letters Patent.
Application filed January 29, 1908. Serial No. 413,288.
Patented Sept. 8,41908.
frame-plates 1, 1, portions only of which are shown in Fig. 1. At one side, the cylinder shafts are extended at 4 and 5 to receive the driving gears through which motion is imparted from the main gear train of the machine.' (For an example of one application of this mechanism see my co-pending application Ser. No. 413,289, iiled January 29, 1908, for improvements in perforating, cutting, and delivery apparatus). Upon the cylinder 2 is mounted a cylinder segment 6, which is adjustably fastened upon the cylinder 2 by means of the countersunk nut 7, which receives a screw stud on the clamping block 8, which slides in a dovetailed groove 9, formed around the cylinder 2, said groove being provided at 10 with an aperture through which the block may be inserted in the groove. At each side of the central groove are shallower grooves 12, adapted to receive plates 11, attached to the under side of the segment to fasten together the two parts thereof formed by cutting the slot for the perforating blade. The cylinder ends are flanged at 13, to hold the block in proper longitudinal alinement upon the cylinder. The segment 6 is provided with a longitudinal groove or chamber to receive the perforatng blade 14. This blade is fastened to a cross bar 15, within said groove, the ends of which project outwardly from each end of the block into engagement with slotted openings at the ends of arms 16 and 17, fastened to a shaft 18 mounted to oscillate in the segment 6. One end of the shaft 18 is provided with an arm 19, upon which is carried a conical roller 20 on a pin 21, said pin being screw threaded and adapted to be adjusted longitudinally in the crank arm 19, by means of the adjusting and lock nuts 22. The roller I20 engages a cam surface 23, cast or otherwise fastened upon the inner face of one of the frame-plates 1,' said cam surface being .fbeveled to correspond with the roller, and being so formed as to impart the necessary 5 movement to the roller and the crank arm 19 to project the perforating blade, when said I blade is approaching axial alinement with the cylinder 3, and to depress the blade immediately it has passed the line of centers between the two cylinders, as will appear from an inspection of Fig. 3. In order to hold the roller 20 against the cam surface and to retract the erforating blade after 'each outward stro re thereof, a coiled spring 24 is placed on the extended hub of the arm 17, one end of 4which spring is fastened to the segment 6, and the other end to a collar 25 adjustably mounted upon the shaft 18,`
whereby the tension of the spring may be re ulated as re uired.
- 7hile the per orating blade may be used in conjunction with any form of receiving, or female cylinder, I preferably form said receiving cylinder with a plurality of circumferential grooves as illustrated in Fig. 1 g into which grooves the teeth of the perforating blade enter, when ejected from ,the segment. By employing this Agrooved c linder, I may set the segment around the cy inder 2, in any position, regkardless of the alinement of the perforating lade with the cylinder 3; and I may also attach additional segments carrying these perforatiiig blades, and` position them about the cylinder 2, as requirement may arise. As der 2 is capable of carrying as many as four of these cylinder segments, each of which and the erforating mechanisms carried thereby wil be the same as that above dcscribed, and operated in the saine manner as they rotate with their rollers in contact with the cam surface 23. This construction will be of particular advantagcwlien the paper is to be provided with separate stubs, coupons, etc., where more than one line of perforations is required upon 'each finished sheet oi' roll at varying distances apart.
B y providing the crank arms with the conicalrollers, mounted upon adjustable crank i `strueted, the web or sheets of pa pins, l ani. enabled to readily adjust the throw of the perforating blade, and to take up wear that thc blade will be caused to be thrown outwardl more or less from the segment, by causing t ie roller to ride higher or lower upon the cani 23. If desired, however, a cylin-` drical roller may be employed upon a corresponding cam surface, and the adjustment of the| blade accomplished in a diiierent manner.
With a perfoiatiiig mechanism so Yconer will -pass freely between the cylinders wit ioutv danger of being carried out of the line of travel by the teeth of the perforating blade, or blades, and no ulling strain is required to beplaced u on t e paper to free it from the teeth. T ie mechanism is made compact and readily adjustable to meet requirements.
