MERRICK MURPHY, OF ST.4 LOUIS, 4MISSOURI.,
IMPROVEMENT INPAPER-BAG MACHINES. i
` Specification forming part of Letters Patent No. 146,774, dated January 27, 1874; application led December 2', 1873. 4
i which the following is a full, clear, and exact y i yy; description, reference being had to the annexed drawing making a part of this specification, in
whichl g y Figure l is a perspective view, part being broken away. 3 position of the spring and knife when the lati lli ter is down. Fig. 2 is a sectional elevation. The dotted lines indicate the position of the spring and knife just before the paper is cut.
The dotted lines indicate the Part of the knife-head is broken away, showing the eccentric and the recess in its periphi ery for the reception of the dog. Fig. 3 is a plan of the lower knife. A
`Like letters of like kind indicate like parts. The object of my invention is to provide a device for cutting paper from a continuous roll into sheets of a desired size rapidly, and it is especially applicable to cutting from such rolls blanks from which paper bags are to be formed. It further consists in having such a construction that; by a simple change of one 1pavrtmerely, any desired outline or configuration may be given to the cut edge of the blank, thus adapting the machine to the production of blanks suitably shaped for various purposes.
`As my machine is to be specially used by me in the manufacture of paper bags, I have shown in the annexed drawing, and will now describe,
the construction when arranged for this purpose.`
Two suitably-arran ged uprights, A A afford bearings for the shaft B, having attached firmly i to it the heads C C. Between the head C' and upright A', and hanging on the shaft B, but fastened rigidly to the upright A', as seen, is an eccentric, D. A portion, a, of the periphery of this eccentric is removed, for the purpose hereinafter explained. The heads C C furnish bearings for a shaft, E, one end thereof passing through the head C', and, beyond said head C', provided with an arm, b. This arm bis opposite the recess afin the eccentric, and operates therein in manner hereinafter explained. Rigidly attached to the same shaft E, and, re-
spectively, just inside the heads C O, are two y similar arms, c o', tha-t project similarly from the shaft E. A cross-piece, d, extends trans versely, connecting lirmlyat the extremities of the arms c c. The inner ends of these arms have lugs c c', which engage with the springsg g', which arc attached to the heads C C. The uprights also afford bearings for the roller F, upon which the paper is wound, and for the two sets of feed-rollers fm m and n u', arranged as seen. The cross-piece d, or striker, is simplya straight piece of metal having a blunt edge. Abed, G, y is arranged beneath the shaft B on a line with y the feed-rolls m and n. To this bed is attached a knife, H, having a serrated edge, whose outline is shown clearly in Fig. 3. This knife lies on its side, so that the paper can pass freely over it, and it extends slightly beyond the `edge of the bed G, as seen.
The paper from the roll having been led through the rolls m my and n n', and motion being given to the drivin g-shaft, and from it, by` suitable gearing, as seen, to the feed-rolls m-m/ and n n', the operation is as follows: As the shaft B revolves in the direction indicated by the arrows, the heads, carrying the striker d, as above described, revolve with it. The arm or dog b moves over the periphery of the cam D until, reaching the point o, the swell of the l cam causes the dog to raise the striker till the dog, falling into the recess a in the cam, allows the springs g g to throw the striker sharply l down in such manner that it makes a vertical blow, severing the paper.` `The dog, immediately passing from the recess a, causes the` striker to rise in season to free it from the pa per and to avoid any interference in the least with the movement of the succeeding portion of the paper; for the movement of the dog imparts a movement upward to the striker that is supplementary to that given by the rotary movement ofthe heads C C. rlhe blank that is cut is ready to be folded into a bag by any suitable devices .which may be attached to and form a part of this cutter, as, for instance, in my machine patented 21st January, 1873, No. 135,145, or be separate and distinct from it. y
The outline of the fixed knife may be varied y at pleasure, the operation of the machine not depending upon any particular configuration. of the cutting-edge of such knife.
By this arrangement of the rotary striker a AUNITED STATES PATENT Orr-reno f vertical blow is given, such being the direction most favorable, and at the same time the obj eotion to vertical strikers, Viz.,interfering with the continuous movement of the paper, is entirely obviated, for with this device the paper moves continuously, Without intermission.
I ani aware there is no novelty in the use of a lower knife having a serrated edge of the irregular outline shown, or in the use of a revolving upper knife, or in cutting,` paper bags or other articles from a continuous roll of paper, and consequently I do not claim such; but
That I claim as my invention, and desire to secure by Letters Patent, is-
specied.
