To all whom it may concern:

Be it known that T, OTTO a subject of the Emperor of Germany, siding at Chicago, in the countyv of Cook and State of Illinois, have invented a certain new and useful Improvement in Intting Machines, of which the following s a full, clear, concise, and exactdescrlptron, reference being had to the accompanylng drawings, forming a part of this speclfica- G. L. 'HIRSCH,

.tion.

My invention relates to paper cutting machines and is more particularly of servlce in connection with the cutting of strips of paper or similar material from rolls of said material. My invention contemplates the provision of, a plurality of cutting devices sultably adjustable to cooperate with suitable rolls whereby to perform the object above set forth.

My invention also includes novel features of construction of especial importance in connection with apparatus of this general character. However, I will explain my 1nvention more in detail by reference to the accompanying drawing illustrating one form of a device embodying my invention, in which:

Figure 1 is a front view of said device; Fig. 2 is a sectional view on lines a-a of Fig.- 1; Fig. 3 is a partial side view 1nd1- cating certain operating mechanism, and Fi s. 4, 5 and 6 are details of construction.

eferring more particularly to Fig. 1, I have arranged my machine so that it may be placed within a box 1 having a side 2 and lid 3. The device is mounted'on the side portion 2 of the box which thereby constitutes a base plate for the device. On

this base plate 21 mount two end frames 4, A, which end frames have two legs 5 and 6, which legs 5 and 6 areheld in the base plate 2 by means of screws as illustrated in Fig. 2. A bracket 7 extends from each,

of the frames 4 and is designed to receive a roll of paper or similar material 8. 1n

' F'g. 5 l have shown more in detail the manbil tit

ner of holding the roll 8 in place. The arm 7 *isprovided with ,an aperture through which extends the bolt 9. The bolt has at one extremity a nut 10 and at the opposite extremity a head 11. A disk 12 is carried by the bolt 9 and when the paper is to be introduced it is placed against the disk 12 which thereby moves toward the right (Fig.

..clamping the v and the BJtlZBIlSIOIl 31. The handle 16 need 5) to permit the paper roll 8 to be put in plac'e. A spring 13 normally holds the disk 12 and the head 11 toward the left (Fig; 5).

Brakes 14 are suitably pivoted on the base plate 2 and pressed upwardly against the The structure roll 8 by spiral springs 15. of Fig. 5 is used only at the left hand end of Fig. 1, whereas'the right hand end is provided with a handle 16 so that the roller 8 may be rotated directly by means of this handle 16 if so desired, this handle 16 being integrally associated with the plate against which the roller 8 presses at the right hand extremity of Fig. 1. A take up roll 17 is also provided having at one extremity a projecting shaft 18 and at the opposite extremity a handle 19. The shaft extension 20 of the handle 19 is carried within a groove provided in the right hand frame 4 (Fig. 1) and is there rotatably held in place by the spring catch 21. The other shaft extremity 18 of the take up roll 17 l is held in a groove 22 of its arm 4: by a plate 23. A catch 24 controlled by a spring 25 holds the plate23 in place normally and a fingerhold permits removal of the plate 23 so that the take up roll may be taken out. This take up roll has a trap door 27 which is mounted to the remainder of the roll by a hinge 28. A pivotally mountedarm 29 normally in the position shown in Fig. 2 normally prevents further inward movement of the trap door 27. When, how,-v

ever, it is desired to fasten a strip 30 of paper within the take up roll the arm 29 is swung around its pivot 1n acontraclockwise direction so that the door 27 may be moved toward the center, whereupon the strip 30 is inserted between the edge 31 oftheroll 17 and the trap door 27 is again moved outwardly against the edge 31. The arm 21 is then swung clockwise until it engages the pin 32, in which position it remains suitably paper between the door- 2 not be used except when it is desired to J dle 16 is used. The vertical extensions of the arms 4.- carry a shaft 35, which shaft is its rotatably mounted in the frames 4%, but which shaft has a flattened portion throughout its length between the frames 4 as shown more clearly in the sectional view of Fig. 2. This shaft carries a ratchet wheel 36 and may be rotated by means of a handle 37.- A spring catch 38 controlled by the spring 39 normally holds the ratchet wheel 36 into whatever position it is rotated by the handle 37. When the-catch38 however is released, the shaft may be rotated in the opposite direction as will be readily apparent. I have mounted upon the shaft" 35 three suitable frameworks each carrying knives 40, 40, 40. These frameworks consistof the arms 41 held in place by means of the headed shaft 42 so as to carry between them'the knife 40,

which knife is mounted'on a hub 43. The free ends of the arms 11 are loosely mounte'doh the shaft"35. Between the arms 41 and on "the shaft 35 is mounted a sleeve 44 c'arrying a'wing screw &5, which sleeve is independent of the arms 41. The sleeve carries suitable springs 46 which press against a bifurcated armi'47, which bifurcatedends are also "held by theheaded shaft"42. The knife-40 impingeslagainst the roll 43am]. when it is desired to" exert pressure by the knife 40 against the roll, then the shaft 35 rotated contraclockwise (Fig. 2) and is held in its rotated position by means of the wheel 36 and awl 38. It will thus be seen that the position of the cutters can be adjusted longitudinally offthe shaft and. the c'uttei framework then fasteiied'in place by use of the spring screw 45, whereafter the shaft 35may be rotated to get the required spring pressure against said cutter. The arm Hals'o carries an extension 48 which carries a guideway or chute 19 for thestrip of paper 50 that is being cut from the strip 30 by .the knife or knives 40. removed if desired or swung out of place so that the severed strip may also be rolled on the take up roll. the wing screws 45 may be loosened, it is. apparent that the knives 40.inay b'e placed in any desired position" on the shaft 35sec as to cut strips of any desirable Width and so as to make it possible to cut a plurality of strips if de- Silfedh g l rom what has been thus set forth, it is the operatinn of my impr nt ed mac ine will be'enti'rely. clear. While I have herein described one chine as embodying various features ef my invention, I do not of'ieourse limit myself to this'specific structure, but

' Having thus described one form of The guides can be iaaeaaa rying out my invention, what I claim as new and desire to secure by Letters Patent is:

1. A machine "of the character described ;,having means for holding a roll of ribbonlike material, a take up roll, means for re- ;-.winding said material, rotatable cutting means for cutting a strip from said material and a-chute for guiding the severed strip, said chute having side walls to confine the longitudinal displacement of said strip.

2. A machine of the character described having means for holding a roller of ribbonlike material, a take up roll, means for rewindingsaid material, an idler roll over which said material is carried, rotatable cutting means cooperating with said idler roll -to... c u t a strip from said material and a chute for guiding the severed strip, 'said chute having side walls to confine the longitudithe longitudinal dis p shaft. carrying said cutting means, means for rotating said shaft to adjust the pressure of said cuttingmeans against said material and a fiat leaf spring interposedbetween said shaft and said cutting means, said means-including a ratchet wheel and" a rotatable spring pressed pawl.

5. In a machine of the character described a take up roll havinga portion of its outer shell pivotally mounted to the remaining portion of the roll, whereby material may be clamped between these'two sections of the roll, and means whereby this pivoted section may be swung inwardly to release said clamp portion to permit removal of the material from thereof. a p r I i witness whereof, I hereunto subscribe jthe saicl roll longitudinally my name this 2nd day of. September, A. D,
