This invention relates to improvements M paper shredding machines of the kind adapted to manufacture paper excelsior from newspapers or the like. Q V
An object of my invention isto provide an' improved paper shredding or cutting machine embodying means for tearing sheets of paper into a plurality of narrow strips and also means for crimping the said strips;
Another object of-my invention is to ro-' vide an improved paper shredding machine embodying novel paper feeding mechanism' which operates automatically to cause onl such amounts of paper to befed to the cutting or shreddin .mechanism of the machine as can he satis actorily accommodated therehvc A still further ohjectof my invention-is to provide an improved paper cutting or shreddingmachine emhodying novel means for.
. manufacturing crimpedfpaper excelsior from waste papersuch as newspapers.
Other objects more or less apparent will present themselves or will he specifically pointed out-in the description to follow.
Inthe accompanying drawings:
structed in accordance with my invention;
Fi g. 2 is a sectional view of the cutting discs, showing their showin'gparts thereof in section.
Referring to the drawings,.thenumerals 1 and 2 represent the spaced sides of a suitable I supporting frame having a motor 3 mounted thereon. i Thesides of the frame are substan- 45- abiy otatably mounted within the blocks 6 and 7, respectively, are the ends of shafts 8 and 9, and each of said shafts have, respectively,
a'series of 10.and11 secured thereon.
. 50. The discs are of circular shape and are pro-.

vided .with sharp cutting edges at their peripheries. The discs of each series rotate with v the. shaft on which they are mounted, and by means, such as nuts 12, they are held in firm contact with one another. The discs 11am so arranged with respect to the discs 10., that the cuttingedges of the former are positionedhetween the cutting edges of the latter, with .a slight clearance between. In order to ada just the clearance, so'that difi'erent thicknesses of paper may he properly'accommodated h the discs, a screw 13 having right and le hand'threads is rotatably mounted'hetween each pair of blocks 6 and 7, with the ends of the same extending into the said blocks. By turning the screws. 13- in one direction the blocks 6 and 7 may be, separated so asto separate the cutting edges of the two sets of discs,
and when turned in the opposite direction the I two sets of discs maybe moved so their out tingedges are brought toward each other.
So as to adjust the positions of the two sets of discs on the progecting parts 4:; and 5 of the frame and without changing their lfiliite t'ive positions, a screw-M is rotatably atyond a bar 15 secured to the ends of the said projecting parts 4: and 5.. A nut 16 on each of the screws M, serves as means for permitting the movement ofthe blocks 7 and 8, as a unit, either toward or away from the bar 15, thereby affording means for. adjusting the posi tions of the-discslO and 11. i
at tached at one end to each of the hloclrsi', with its opposite end extending through and heihe motor shaft is provided with apulley 17 over which extends an endless belt 18, the
said helt also extending over a large pulley i9 securely mounted on the shaft 8. The
shaft 8 carries a" gear 20 which meshes with a gear 21 carried hyithe shaft 9, and thus.
upon the rotation of the'motorshaft, the two sets of discs 10 and 11 maybe rotated in opposite directions. 5
Rotat'alilymounted on the frame and within suitable provided thereon, are
purpose of having the plate 31 above the belt 30 is to enable only a certain number of sheets of paper to be carried toward the cutting discs,
forward roller'29'is provided with a pulley 29, while the shaft 23 is provided with a pully 23a of approximately the samesize.
An endless belt or chain 32"ex tends rover,
pulle s29 and 23a thereby enabling thebelt 30 t0 shaft 23'.
q Rotatably mounted on the frame at points adjacent the roller 29, is a roller 33 havin its ax s located in suitable bearings provi'd on "said frame. Also located on the frame at points adjacent the roller 23 is a roller 34 which has its axis also rotata ly mounted in suitable bearings provided on he said frame,- An endless. belt conveyor 35 exte 'ds over roll-.
.ers 33 and 34 and serves to receive quantities of paper, sheets from the conveyor belt 30 and carry them to the conveyor belt 24. The
Theaxis of the.
actuated from power exerted'through with the gear ated in the same direction at a'considerably' greater speed.
Located directly above the roller 34 is a spring pressed roller- 38, the axis of which is rotatably mounted in blocks movably located in upwardly extending supporting members 39 secured tothe sides 1 and 2 of the frame. Suitable springs interposed between the tops of the. supporting members 39 and the blocks within which the axis of the roller 38 is mounted, serve to press the said roller downwardly so it normally and yieldably presses 'against the conveyor belt 35.
v Rotatably mounted on suitable brackets 40 which are secured to the sides 1 and 2 of the frame, are the axes of a plurality of rollers 41, the said rollers being spaced above the uppersurface of the conveyor belt 35 and separated from each other by an intervening space. The space located between the rollers 41 are connected by a series of pulleys 42 and to permit the passage of paper sheets of a thickness corresponding to the capacity of the machine. The axesof the rollers 34 and 41 are connected by a series of pulleys 42 and belts 43,- thereby enabling the said rollers 41 to be rotated through the power delivered to the gear 37 of roller 34. The rollers 41 are rotated in a clockwise direction while the conveyor belts are being rotated in the same direction. If there is too much paper delivered'to the conveyor belt 35 by the first Iconveyor belt 30, the rollers 41 hold back the excess quantity thereby enabling the conveyor belt 35 to only deliver a suflicient thickness of paper sheets to conveyor belt'24 as can be properly accommodated by the space between the cutting edges of discs 10'and 11.
In order to cause the strips of paper passing from the cutting-discs 10 and 11 to be cr1mped,-I have rotatably mounted a pair of longitudinally corrugated drums 44 and 45 whereby they intercept the said strips of paper falling from -the said discs. The axes of' the drums are rotatably mounted in the -on the forward part of the frame in positions i sides 1 and'2 of the frame, with the corrugations of one drum meshing with the dormtions'offthe other. The axis of drum 44 is provided with agear 46 which meshes with an idler gear 47 sup orted at the sidel of the frame, the
25 secured to shaft 8. Thus when the shaft 8 is rotated by the motor 3,
'the drums 44 and 45 are rotated in opposite directions. The strips of paper passing from the cutting discs 10 and 11 fall onto the corrugations of drum 44 and are carried ferwardly between the two drums, after-which they are crimped and fall downwardly. The drum 45 is rotated by the drum 44, the corrugations being in mesh and acting inthesame manner as 'intermeshing gears.
said i ler gear being in mesh.
A number of sheets of waste paper is ordinarily placed by the operator on the conveyor belt 30 whiclicarries a certain portion thereof-to the conveyor belt 35. 'The conveyor belt finally delivers a certain amount of the paper to conveyor belt 24, which in turn carries the paper-to the set of discs 10, after which it passes between the cutting edges of discs 10 and 11 and is.cut or torn into a plurality of strips. The strips fall onto the corrugations of drum 44 and thereafter are carried between the two drums 44 and 45, finally emerging therefrom with transversely disposed crimps located therein. The crimping of the strips, enables air to enter between the contact strips, thereby causing the individual strips to separate one from the other as they fall from the drums.
the said conveyors being am Eed ment and synchronized with}: e mechanism, and means synchronized with the conveyors and mounted adjacent one of the belt conveyors for rejecting sheets of said paper over and above a certain thickness whereby 'a stack of said sheets of pa r of a certain thickness, may be delivere to the shredding mechanism at a given time.
In testimony whereof I have aflixed my signature. HARRY W. WILSON.
