Specification of Letters Patent.
Patented Dec. 12, 1905.
Original application filed April 13, 1904, Serial No. 203,053. Divided and this application filed n15 3, 1905. Serial No. 268,195.
To atZZ whom, itmay concern:
Beit known that I, ALFRED GEORGE BAKER, a British subject, residing at Dunedin, New
Zealand, have invented new and useful imthe claims.
This case is a division of my application for Letters Patent filed April 13, 1904, Serial No. 203,053.
In the accompanying drawings, illustrating the invention, Figure 1 is a perspective front View of the machine. Fig. 2 is a perspective rear view of part of the machine. Fig. 3 is an enlarged cross-sectional view through A B of Fig. 1. Fig. 4 is an enlarged longitudinal sectional view of part of the cutter-roller. Fig.
5 is an enlarged view of part of the directing plate.
A base-plate 1 has standards 2, 3, and 4 secured thereto or integral therewith. The standards 2 and 4 are provided with bosses bored to form bearings for a shaft 5, mounted therein. On one side of the standard 2 are pulleys 6 and 7 on the shaft5 for the purpose of connecting power by means of a belt for driving the machine, and on the other side of the standard 2 is a fly-wheel 8, keyed to the shaft 5. A pinion 9 is keyed to the end 10 of the shaft 5, so as to gear into a spur-wheel 11,
keyed to a second shaft 12, mounted in bear-' ings formed in the boss 13 on the standard 3 and in the boss 14 on the standard 4. The spur-Wheel 11 forms also a disk-crank the pin 15 of which is connected by means of a connecting-rod 16, provided with swivel-joints 65, to the outer end 17 of a lever 18, to which a chisel-edged shearing-knife 19 is adjustably secured, the inner end of the lever '18 being pivoted to a lug 20 on the standard 3, and by these means the adjustable shearing-knife 19 oscillates up and down as the spur-wheel 11 revolves. A disk-crank 21 is keyed to the shaft 12 at the opposite end 22 to that on which the spur-wheel 11 is keyed and is connected to a slotted lever 23 by the pin 24 and the connecting-rod 25. The pin 26 slides in the slot 27 in the lever 23 and may be secured to the lever in a desired position for the purpose of regulating the stroke of the lever. A pawl 28, pivoted to the lever 23, is adapted to engage the ratchet-wheel 29, keyed to the shaft 30, and a pawl 30, mounted in the base-plate 1, is adapted to engage said ratchet-wheel 29 to prevent it springing backward when in action. The lower end of the lever 23 is pivotally secured to the shaft 30, which is supported at one end 31 by a bracket 32, bolted to the base-plate 1, and also by bearings in the bosses 33 and 34, cast integral with the roller-frame hereinafter described.
The ratchet-wheel 29 operates the feed-roller 44 and the cutter-roller 40 as follows: The pinions 35 and 36, keyed to the shaft 30, gear into spur- pinions 37 and 38, fixed one on each end of the spindle 39 of the cutter-roller 40, said spindle being supported in hearings in the roller-frame. The spur- pinions 37 and 38 on the spindle 39 of the cutter-roller 40 gear into spur-pinions 41 and 42 on the spindle 43 of the feed-roller 44, said spindle 43 being also supported in bearings in the rollerframe.
A leading-roller 45 hasits spindle 46 mounted in bearings slidable in vertical slots 47 and 48 in the cheeks 49 and 50 of the roller-frame for the purpose of adjustment to secure horizontal delivery of the sheet of material. Guidepieces 51 and 52 are attached to the cheeks 49 and 50 of the roller-frame to prevent the material springing and to assure an accurate lead for a sheet 53 of material, such as lead, to the cutting-roller 40. The sheet 53 is fed through between the cutting-roller 40 and the feedroller 44 and out into strips by means of the disk knives 54, more clearly illustrated in Figs. 3 and 4. V
The cutting-roller 40 is built up of a series .of washers 55, Fig. 4, and disk knives 54, provided with sharp cutting edges 54, placed side by side alternately on a spindle 39, so as to enable the disk knives to be removed for repairs or grinding. The diameter of the disk knives 54 exceeds the diameter of the Washers 55, so that they may cut sheet 53 into strips. The feed-roller 44 is slightly milled, so as to afford a grip of the sheet of lead and draw it through without twisting it. The diameter of the feed-roller44 is slightly greater than the diameter of the cutter-roller 40 and disk knives 54 together, the difference being preferably one one-hundred-and-twentieth of an inch in aroller of three inches diameter,so that when a slight notch 44 is formed in the periphery of the feed-roller 44 the diameter of the notched portion Will be equal to the diameter of the cutter-roller 40 and disk knives together, the object being to cut the sheet of lead clean and give even travel thereto. The feed-roller 44 is provided with shallow grooves corresponding to the edges of the cutter-disks, so that for thin sheets the edges of the disks may travel in these grooves, and for thicker sheets the feed-roller is raised, the limit of adjustability being reached when the edges are flush with the surface of the feed-roller.
The sheet after being cut into strips is forced by means of the feed-roller 44 and the cuttingroller 40 between two plates 56 and 57. One edge 58 of the lower plate 56 is'supported by a bracket 59, attached to the base-plate 1 between the cheeks 49 and 50 of the roller-frame. The inner edge 60 of the lower plate 56 is supported by the washers of the cutting-roller 40. The edge of the plate 56 is serrated and beveled to lit the disk knives 54 and Washers 55 on the cutting-roller for the purpose of preventing the strips of material from clinging to the cutter-roller and being carried round said roller. The upper plate 57 is also supported by the bracket 59. Liners 62 of a thickness equal to the thickness of sheet-lead used are placed between the brackets 59 and the upper plate 57 to keep said upper plate 57 that distance from the lower plate 56. A lower knife 63 is secured to the bracket 59. As the material already cut into strips passes out between the plates 56 and 57 the shearingknife descends and, in conjunction with the lower knife 63, cuts the material into cubes. A lug 64, forming part of the upper plate 57, is provided for the purpose of guiding the shearing-knife past the cutting edge of the lower knife 63.
The machine is constructed so that by the revolution of the shaft 12 the slotted lever 23, pawl 28, and ratchet-wheel 29 will by means of the rollers first force the material out between the plates 56 and 57 in strips a desired distance, and then the slotted lever carrying the pawl returns for another stroke, while simultaneously with such return the shearingknife 19 descends and cuts off the strip of material into cubes and then returns, whereupon the slotted lever begins its former motion.
Having now described my invention, 1 declare that what I claim as new, and desire to secure by Letters Patent, is'- 1. A machine for cutting material into strips and blocks comprising a feed-roller and stripcutter roller, means for rotating said rollers in unison, a ratchet-wheel operatively connected to one of said rollers, a rocking lever, a pawl carried thereby engaging the teeth of the ratchet-wheel, an operating-shaft, a crank,
a link having one end connected to said crank and the other end adjustably connected to said lever, a pivoted knife-blade for severing the material after leaving the rollers, and operating connections between the knife-blade and operating-shaft, substantially as described.
2. A machine for cutting material into strips and blocks consisting ofa feed-roller and adisk strip-cutter roller, said rollers being geared together, a ratchet-wheel, geared to one of said rollers, a slotted lever, a pawl carried thereby engaging with the ratchet-wheel, a shaft 12, a crank connected to one end thereof, a pin adjustably secured in the slot of the lever, a link connecting said pin with the crank, a crank on the other end of the shaft 12, a lever having one end pivoted to the framework and a swiveled connection between the other end of the lever and the last-named crank, a knife on said lever adapted to cut the material after it leaves the disk cutterroller and means for rotating the shaft 12.
Intestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ALFRED GEORGE BAKER.
