THOMAS TULLY, OF SPRINGFIELD, ILLINOIS.
Specification forming part of-Letters Patent No. 127,716, dated JuneA l1, 18.72.
To all whom it may concern:
Be it known that I, THOMAS TULLY, of Springfield, county of Sangamon,and State of Illinois, have invented new and useful Improvements in Machines for Cutting Leather or other similar materials; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing and to the letters of reference marked thereon making a part of this specification, in which- Figure 1 is a side-elevation. Fig. 2 is a top view with the knife-stock removed to show the strippin g-wires below, at'i t' z'. Fig. 3 is an end view. Fig. 4 is a bottom view of the knifestock. Fig. 5 is a sectional view of knifestock, stripping-wires, the cutting-bed, and the connecting eccentric rods. Fig. 6 is a sketch of the sheet of material cut by the knives.
Nature and VObject of the Invention.
This invention relates to the manner of cutting leather or other materials, so that the same may be pulled or stretched out laterally and form a net-work for horse-covers and other purposes without thev expense of knitting or fastening the meshes together; and consists, first, in arranging the knives in alternate series in the same stock, so that the cuts of the knives will accomplish the purpose, as hereinafter more fully described; secondly, in the arrangement of stripping-wires, in combination with the knives, over the material, so that the same will be prevented from rising with the knives; thirdly, in the manner of connecting the ratchet-bar with the eccentric rod, whereby the feed motion is intermittently fourthly, inthe general arrangement of parts hereinafter more fully described as a -combined machine.
In the drawing, A represents the side frames, which are ofmetal and made sufficiently strong to sustain the feed and other rollers which are to be properly journaled into them. A' are foot pieces, permanently fastened to or cast with the side frames, and are to be bolted to the bed B, or floor, or any other convenient device. A" are tie-rods for binding the frames properly together. C, C', D, D', E, and E' are gear-wheels on the ends of the feed-roller shafts, which are made to mesh into each other. D" is a ratchet-wheel, fastened to the outside of cog-wheel D. F, F', G, and G' are the feed-rollers. v H is the knife-stock. H' is the bed on which the material rests when cut. a is the main shaft, by which motion is communicated to the machine by the handle b b'. On this shaft lare the eccentrics .c c, around which are the straps d" d", elongations of the connecting-bars d d, which are pivoted to the upper end of the knife-stock H, one on each side. At d' the ratchet connecting-bar e is pivoted, and which is moved laterally by the revolution of the main shaft a. This bar e is pivoted, by a thumb-screw, e', to the ratchetpawl bar f at f', where there are two holes, one giving the proper feed for the cuts in the material to form the reticulated part, and the other allows the knives to cut the whole distance and form the fringe. f operates the pawl g, which is kept down by the spring g'. h and h' are the cutting-blades, fastened into the stock in any convenient manner.l c' t are the stripping-wires, arranged one on each side of a blade and fastened into strips t" i', which are fastened by any convenient method to the side frames A A.
Operation.
The material, properly prepared, is fed into the machine from the left side of Fig. 1, between rollers F and F', and by turning the crank the eccentric a brings down the knifestock H. At the same time the lateral movement of the bar d to the right carries the rod e with it and pulls the crooked lever j', and the pawl g moves the ratchet D", which, being fast to the gear-wheel D, causes it to revolve and carry with it the under roller F', at the same time moving the gear D, which is on the upper roller F, which also moves 5 and as on the other end of F the large gear E is fastened, this gear E revolves and carries with it the gear E', which is on the end of the lower roller G', and which roller being moved the gear C' on its end carries with it the gear C on the end of the upper roller G, and thus the direct motion given to the two feed-rollers F and F' by the action of the ratchet D" is transmitted to the take ott77 rollers G and G', all
moving in the same direction 4coinoidently and stopped when the pawl is released in the up- Ward motion of the knives by being moved backward in the revolution of the eccentric o. The connection of the pawl g with the rod al is so arranged that the'intermittent feed is precisely adapted to leave a short space-say, one-quarter of an inch-between the cuts of the knives; and by shifting the thumb-screw to the other hole, at f', the material is cut cntrely the distance required for the fringe. The knives are about three inches in length, and the distance between them corresponds with the width of the strand it is designed to have the net. The knives are set in the stock in two rows, which lap each other nearly onehalf their length.
Having fully described my invention, what l claim, and desire to secure by Letters Patent of the United States, is
1. The alternate arrangement of the knives h and h in two rows, substantially as and for the purpose described.
2. The combination, in a leather-cutting machine, of a series of knives and a series of stripping-wires, when arranged for operation, substantially as set forth. u
3. The ratchet-connecting rods e and f, with the connecting eccentric rod d, substantially as and for the purpose described.
4. The combination of the spur-gear wheels on both ends of the feed and take-off rollers with the ratchet-feed arrangement and the knife-stock, all operated intermittently by the eccentric c, substantially as and for the purpose described.
Signed this 10th day of October, 1871, at the city of Washington.
