MULTIPLE SCORI ENG AND SLITTING DEVICE Filed May 29, 1926 INVENTOR f 'wmdm fie fbmpi/zk M ZwJa/M/ 4Z4 ATTORNEY Patented Oct. 1, 1929 UNITED STATES PATENT caries MULTIPLE SCORING AND SLIT'I'ING DEVICE Application filed May 29,

This invention relates to devices for ruling, slitting and scoring paper passing through a cylinder printing press in the direction of its length.

The device possesses several distinctive ad vantages, one of which is that it is arranged in the form of an attachment capable of being adjustably applied to the bed of a press and having a pivoted head carrying the knives, etc.

A further feature is in the provision of a head, spring pressed againstthe press cylinder, adpistably mounted on its support and capable of yielding, thereby avoiding any possible damage, either to the cylinder or to itself.

Another object is to provide a head having a manually removable spindle on which may be mounted one or more cutters, perforating discs or ruling rollers all of which are readil interchangeable.

These and allied objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a side elevational view of an embodiment of the invention, illustrating its application to a conventional type of cylinder printing press.

Figure 2 is a front elevational view of the device as dismounted.

Figure 3 is a longitudinal sectional view taken substantially on line 3-3 of Figure 2.

Figure 4 is a transverse sectional view taken on line 4-4 of Figure 3.

Figures 5 and 6 are detail views of the cutter carrying spindles used.

The numeral 10 is used in the drawing to designate in general the bed of a press on which is mounted a chase 11, carrying a type form 12, the same being movable conjunctively with an impression cylinder 13, between which' the paper is passed, these elements being common and well known.

A rail 14, secured steadfast transversely of the press bed, relative to the axis of the cylinder, is used as a support for one or more heads 15, the lower part of which presents clamp elements 16 movable along the rail and 1926. Serial 110. 11.2579.

These sides contain round registering openings 23 to receive interchangeable spindles 24 or 25, differing in length, each spindle having an enlarged head 26 at one end and an annular groove 27 adjacent the other end,

these grooves being adapted to receive the inner end of a detent pin 28 mounted in a drilled opening intersecting the passage 23 in one of the forks 22.

The pin 28 extends outward beyond the opening in the fork and is provided with a fixed collar 29 to receive the thrust of a flat spring 30, retained on the pin by upsetting its extremity as at 31, the free upper end of the spring extending into a position easily accessible by an operator in retracting the pin, while the'lower end of the spring is fixed on the side of the block by a screw 32. 1

From the foregoing it will be seen that the spindles are readily removable by merely grasping the extending end of the spring 30,

and pressing it outwardly sufiicient to clear the detent from the groove, and it will be understood that these spindles are used as arbors or mandrels for the circular cutters 33, sim- 8 ilar ruling discs or perforators 33? all of which are interchangeable and mountable between the forks 22, the discs being spaced by one or more washers 34 to vary the distance between the marks made thereby. It will also be seen that the discs are bevelled on one side and they are reversible to further vary this distance.

If it be preferred, the perforating disc 33' may be mounted on the extending portion of ,95

the longer spindle 25 and held in position by suitable collars as seen in Figure 2, thus providing a multiple mounting.

A single raised lug 35 at the rear of the head 15 is drilled and screw threaded to re- 1 00 ceive a bolt 36 suited to pass through an opening 37 in the block 20, this opening being larger than the diameter of the bolt .and counter-bored, as at 38, to receive the enlarged head 39 of the bolt.

Rigidly fixed on the outer end of the bolt I 36 is a knurled actuating knob 40 by which the bolt may be easily turned, and operable on the bolt is a knurled look nut 41 to maintain it in adjustment.

A coiled compression spring 42 encircles the bolt to abut the inner surface of the lug 35 and the adjacent surface of the block 20, acting to press the same outwardly and the cutters 33 against the cylinder to any desired extent.

It will be seen that the block is adjustable across the length of the cylinder, can be adjusted contactually with respect to its peripheral surface, and is yieldingly mounted; it is also clear that several scoring, slitting or perforating discs can be accommodated at the same time and that substitution is rapidly and easily effected without the use of any tools Whatever, fingers alone sufiicing.

Although the foregoing is descriptive of the preferred embodiment of the invention, it Will be apparent that minor changes may be made in its construction, without the exercise of invention or conflicting with the scope of the claim hereto appended.

Having thus described my invention, what- I claim as new and desire to secure by Letters Patent is In a multiple scoring and slitting machine, a head having clamping elements,lugs formed with said head, a block pivotally connected at its lower end to said lugs, said block having an opening therethrough, an adjusting bolt extending through said opening and the front of said head, a spring on said bolt interposed between the block and the head, a turning knob and lock nut on said bolt, the

upper portion of said block being fork shaped and having a removable spindle mounted therein, scoring discs rotatably mounted on said spindle in said fork, one or more Washers interchangeably mounted intermediate said disks to permit varying the distance between the score marks and a perforating disk on one end of the spindle outside the said block,

all of said disks being located above the head of the machine.

In testimony whereof I have signed my name to this specification.

GENNARO DE PAMPHILIS.
