ROBERT WILLIAM VILTON, OF LONDON, ENGLAND.
APPARATU S FOR CUTTING PAPER, 800.
SPECIFICATION forming part of Letters Patent No. 509,989, dated December 5, 1893. Application filed February 16, 1893. Serial No. 462,629. (No model.) Patented in England November 29, 1892. No. 21,818.
To all whom it may concern.-
Be it known that I, ROBERT WILLIAM WIL- TON, a subject of the Queen of Great Britain, residing at 49 Albany street, Regents Park, London, in the county of Middlesex, England, have invented certain new and useful Improvements in Apparatus for Cutting Paper and other Materials, (for which I have applied for a Patent in Great Britain, No. 21,818, bearing date November 29, 1892,) of which the following is a specification.
The object of this invention is to construct an apparatus for cutting paper, leather, textile fabrics and other materials, such apparatus being especially applicable to cutting ofi printed sheets from a continuous roll of paper. Now according to this invention I provide two shear blades or knives each blade having two cutting edges. Each blade is fixed in a reciprocating frame which I cause to move vertically or horizontally by means of cams, cranks and connecting rods or other suitable means.
In order that my said invention may be fully understood I will proceed to explain the same with reference to the accompanying sheets of drawings in which- Figure 1 represents an elevation of an apparatus constructed according to this invention for cutting off printed sheets such as newspapers from a continuous roll of paper. Fig. 2 is section of same; Fig. 3 a plan of same. Fig. 4 is a modification of same adapted for cutting paper shavings.
The same letters denote the same parts in.
all the figures.
a is the frame of the machine; I) and c the knives or shears fixed in reciprocating frames d e. The frame at is connected by links ff to levers g g. These levers are keyed to sleeves h h and oscillate on the shaft 1;. The levers g 9 also have at one end a roller engaging with grooves in the cams jj which are keyed to the cam shaft 7a. The frame 6 is also connected by links 1 Z to the levers m m which are keyed to the shaft 'i, rollers on the end of the lever engaging with grooves in the cams n n which are keyed or otherwise secured to the shaft 7a.
In order to insure that the cutting edges of the knives shall always be in close contact the frames (1 e reciprocate between rollers o 0 and r r whereof the rollers 0 0 are secured to the shafts p p rotating in bearings q (1 fixed to or forming part of the frame a of the machine and the rollers M are secured to the shafts s s which rotate in blocks 8 s which slide in the plumber blocks 8" s.
The pressure of the rollers -r r on the frames d and e is regulated by means of springs H the compression of which is adjusted by the screws 10 'u, and hand wheels 4; '2). By this means absolute contact of the cutting edges is insured at all points without undue pressure.
To avoid injury to the cutting edges of the knives I arrange that when the knives are farthest apart the cutting edges are in contact at the ends as shown in Figs. 1 and 4. w is the table to carry the paper to be out between the knives. It will be evident from the shape of the cams that the blades are caused to rapidly pass one another and remain sta tionary until the next sheet is printed. When another quick cutis made the blades again remain stationary until another sheet is printed and so on the cams imparting a rapid motion to the knives or blades with a period of rest between each cut. As each blade has two cutting edges two sheets are cut off during one revolution of the shaft 2', that is to say when the frame e is depressed and the frame (1 raised and also when the frame 6 is raised and the frame 61 depressed. If the blades 12 and c are parallel or nearly so the cutting is practically instantaneous. m :r are fast and loose pulleys to receive a driving belt. It will however be found in practice preferable to drive the cutting apparatus by means of a pitch chain. or other positive means of transmission from the printing machine.
' Fig.4:shows amodified form of the apparatus adapted for cutting paper or other material into small shreds or shavings the frames d and (2 being reciprocated by means of the cranks A. A. B B and connecting rods 0 G and D D respectively. F F are pedestals or plumber blocks in which the crank shaft N rotates. The frames (1 and emay in this case move in fixed guides the knives being adj usted by screws attached to the frames in the usual way. The material to be cut is fed slowly forward between the knives and a sh avingor shred of any desired width (according to the rate of feed) is cut at each reciprocation.
The material may be fed to the knives by means of rollers as in hay cutters.
Having now described my said invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an apparatus for cutting paper and other materials the combination'of two reciprocating blades or knives each blade or knife having two cutting edges with a device for reciprocating the same for the purpose stated.
2. In an apparatus for cutting paper and other materials the combination of two double edged knives or blades 1) and a secured to re- ROBERT VILLIAM WILTON.
