, whickthe following is a full, clear, concise,

and-exactdescription, reference being had to the=accompanying,drawmg, forming a part ofthis: specification.

This-invention relates to improvements 1n perforating machines, the ob ect. being to improve the wearing, qualities of the machine {and o'simplify and cheapen the construction t Oneemhodimellt ofthe invent on is illustratedin the accompanylng drawings and 1t will be,obvi0us;that -the improvements may beappliedmo. various forms, s1zes and types of: machines and; thatthey may differ in structural respects, all within the scope of the appended claims.

In=the e drawings Figure 1 is a side elevationo a simplehand machine, parts being-lbrokenaway to show more clearly the features; of improvement; Fig. 2 1s a crosssectional view, thev plane of section bemg indicated by, the line 2- -2 of Fig. 1; Fig. 3 is=:a perspective detail view of the fixed mandrel on the. movable head of the machine; and Fig. 4; is a similar view of one of the rotatablematrix rings.

This machine in general is of the type used for perforating numbers, letters, words or other data, through one-or more sheets of paper, as, for example, checks. It 1nclndes. a. plurality of groups of small punches, some of. which punches m each group are depressed. when the machme is operated to perforate the deslred letter, figure or..character,- In order to select the proper punches in each group for such perorations, the operating head of the machine. is provided-with a matrix ring or late for each-group of punches, at least ot-5 any group in which it is deslred to chan e-the character of perforatlon made by it. 'l he ,ring is provided at different points with groups of holes adapted when any such point .is brought opposite the ends of the punchesand the head depressed or moved toward the goup to receive the ends of the non-perforatin punches. The remainderof the punches o the group are pressed forward by the solid portion of the ring, or plate and serve to perforate the desired character in the sheet.

The present invention relates to improvements in such machines whereby the head:

or punch operating means may bemade much more cheaply and expeditlousl than heretofore and the wearing and lasting qualities of the same be much improved.

Referring to the particular machine, of the drawings, the baseportions 10 and 11- of suitable form and material are bolted orotherwise fastened together to form a rigid member, the two parts being slightly separated at their forward ends to form a slot or mouth to permit the insertion of a sheet or sheets to be perforated. A suitable die plate is carried in the lower portion 19 to cooperate with thepunches 12 in making the perforations. The adjacent part of-the upper member 11 is provided with a suitable guide plate for the-lower endsof the punches, anda plate 13 secured to the upper side edges-of this same part forms a guide for the upper end of the punches.

The upper portion of the machine con: sists of a suitable hollow arm 14, usually of nest metal, pivoted at its rear end to the base portion 11, and carrying the operatinghead at its forward end. To the crossmember 15 near the forward end of this .arm and between its two side members 16,

and 17 is secured a suitable mandrel,18:-by.

means of the screw bolt 19. This .mandrel is cylindrical in form and carries the rotata ble matrix rings 20. A front plate 21having an annular shoulder to fit within-the side members 16 and 17 is secured by screws 22 to the forward ends of the said members-16 and '17 and serves to end of the head.

A. lifting plate 23 for .the punches is carried by the head between a ledge formed on the inside lower-edge of the extension of the front plate 22 and a suitable slot or groove.

in the corresponding extension of thecross member 15. Said lifting plate is adapted to reciprocate vertically between. the side members of the portion 11 of the base and when raised to engage suitable shoulders on;

inclose the forward h 95 the punches 12. When the head is depressed this plate permits,v the punches to be depressed also;

A suitable hand lever 30 is pivoted to the upper ends of a link 31, which in turn is ivoted to the portion 11 of the base. This ever has a pro ection 32 engagmg the upper end of a coiled spring 33, WhlCh rests at its lower end upon the upper side of the base portion 10. The lever is operated to depress the head and when released both lever and head are raised by thespring.

The rings 20 are sections of comparatively thin tubing, preferably steel, and of such size as to nicely fit over the cylindrical mandrel 18. There should be sufiicient clearance to enable them to be easily rotated thereon. These rings 20 are provided at various points about their circumference with suitable apertures arranged to permit ends of the punches so that there will be sufiicient clearance space for their upper ends after they pass through the ring 20. In the upper side of the mandrel 18 is a groove 35 into which a pin 36 for each ring is inserted when the ring is brought to the desired position with the proper matrix over the punch group.

The rings may be provided in any deslred number; four are shown in the present in- I stance. Any desired matrix may be made in such rings. The groups of punches may varyin number and size. The rings may be turned by hand or automatically and any desired number of matrices within practicable limits may be placed in the rings. The machine may be operated by hand or power. With a different form of mandrel or supporting back, the matrix plate may differ, and separate plates, flat or otherwise, for each matrix may be employed. In short, the invention as defined by the claims is not confined in its application to the particular form of machine shown nor to one operating in the same way. I

By placing suitable markings adjacent the holes in the rings through which the pins 36 pass, the operator can tell what pattern is above the punches of that ring and can set the rings accordingly. The patterns may conveniently be so disposed in the rings that the turning of the ring by the pin 36 until the pin strik the upper edge of the side member 17 bri fi gs the next hole in the ring in line with the groove 35, into which the pin may then be inserted to hold the ring in proper position. Or the rings may be turned by the fingers to the desired position. A suitable shield 37 of sheet metal may be secured to the head to entirely cover tion.

By making the mandrel or supporting back of enlarged diameter and grooving it for the punch ends and making the rings or pattern plate of thin material, the cost of the raw materials is greatly reduced since stock materials may be used; the cost of labor is likewise greatly reduced, since the only machining required is the simple operations of making the grooves in the mandrel and drilling the holes on the thin rings, and a longer wearing device is produced since steel may be employed for the rings in place of softer metals. By the use ofnthe thin matrix material together with a suit able backing or support, the invention adapts itself to fields of use not heretofore contemplated for perforating machines, particularly where a plurality of papers or documents are to be marked for each of a list of names or other identifying indicia,

the opening in the front end of the base porplates carried by and movable with said.

head for causing said punches to operate, and means permitting the removal of any of said matrix plates from said head and the substitution of others therefor. 7

2, In a perforating machine, a groupof punches, and an operating head therefor, said head including a comparatively thin matrix ring having perforations to receive the non-perforating punches of the group, and a supporting mandrel for said ring, said mandrel having a space to receive the ends of the punches that extend through said thin matrix plate during the perforating operation.

3. In a perforating machine, a plurality of groups of punches, and an operating head therefor, said head comprising a fixed cylindrical mandrel relatively movable toward and away from the ends of .said groups of punches, a plurality of matrix-rings carried on said mandrel, one for each group of punches, and rotatable on said mandrel, each of said rings having a plurality of groups of openings corresponding to the non-perforating punches of each character to be perforated, and said mandrel having a groove formed therein opposite said groups of punches to receive the ends of said nonperforating punches when they project through the matrix rings in the perforating operation.

4. In a perforating machine, the combination with a plurality of groups of punches, of a mandrel, a plurality of matrix rings on the mandrel, one for each group of punches, and groups of apertures in the rings to accommodate the non-perforating punches of each group.

5. In a perforating machine, the combination with a base, of a plurality of punches supported on said base, a movable head, a plurality of comparatively thin matrix plates carried side by side on said head and movable therewith, said plates being movable relative to said head and having means whereby they cause the depression of a predetermined number of said punches according to their position on said head, and means permitting the removal of any of said matrix plates from said head and the substitution of others therefor for causing a different operation of said punches.

In witness whereof, I have hereunto subscribed my name in the presence of two witnesses.
