TO ALL WI-IOM IT MAY OONCERN: Be it known that wai-Hom; W. MAUZY, of the city of Richmond, county of Wayne, and State of Indiana., and JAMES HUGHES, of Cambridge city, county of Wayne, and State of Indiana, have invented new and useful Improvements in Straw-Cutters; and we do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making part of this specification, in` which Figure 1 is a. perspective View. Figure 2 represents the feeding arrangement. y Figure 3 represents the cap and spring for holding down .the straw and top roller. V Figure 4 represents one of the side pieces, on which is one of the hearings for the shaft on which the l cutting-knife is secured, andslot in which the top roller revolves, and hole for journal of bottom roller to revolve in, and also slot in which the cutting-bar is secured.

Figure 5 represents the cutting-bar. l

A, in g. 1, is a cuttingdiox and frame.V B is the adjustable cutting-bar, seen through the side piece I), also seen at fig. 5, which may be made straight desired, in place of the shape represented. C is thecuttingknife; 'D'D, the two side pieces or supports for the bearings in which the shaft or journals revolve, one of which is more plainly shown at fig. 4. E-,E arethe two' feed-rollers; F F, the tworatchet-wheels on the ends of the l shafts of the feeding-rollers, also seen at fig. 2. G is a cap, represented by red'lines, and held down by means of the woodensprings H H, one of which lis not seen. 'H H are springs for` supporting and holding down the ix cap G. I One of said springs is not seen in igf. 1, both are fully shown at in iig. 3. I is oneof the pawls,

i, also shown at fig. 2. c is an upright piece. L is av cam-rod, shown also at fig. 2. M is a com, also seen at Ji iig. 2,. N is a ily-wheel. O is a cog-wheel. Pis a pinion; Qa cap, represented by red dotted lines, nia'de of sheet iron, to protect against accident'. R is a pnwl for holding the ratchet of the lower roller; S, a slot crossv wise at the end of the bar B, alsoseen at'g. 5; T, one of the bolts which secures the bar B to the frame inthe slot W iu the side piece D. Said side piece is more plainly seen at iig. 4'.V U is a spout for the cut straw to run down from the knife to the door; V V, the hubswith arms, to which the knife is attached. W, in g..4, is a slot in the side piece D, to receive the end ofthe bar B, where it is rmly bolted, and inwhich it may be moved at pleasure by loosening the screw-bolt T, as seen in fig. 1. X X, in fig. 1, arevslots, in which the top Aroller revolves, and is permitted to rise and fall .while the machine is in motion. Oneof said slots` is more plainly shown at :e in iig. 4. Y, in iig. 4, is a' round hole, not seen in either side piece D, in fig. 1, but with which each is provided; an'd in which the journals of` the lowerV feed-roller revolve. Z, in fig. 1, isa clamp which forms a circle with the rbd L, enclosing theA cam M, more plainly seenat Z in fig. 2r G1, in g il, is `a vibrating lever, also seen at Grl invg. 2. Hl is a pawl, also seen atHl in iig. 2. 1 1, in fig. 1, are bolts by which the clamp Z and rod L are fastened together, also shown at iig. 2. 2, in tig. 1, is the shaft on which theknife O, pinion P, cani M, and {ly-wheel N are secured. 3, in iig. 4, shows one of the bearings in which the Vfly-wheel shaft -revolves, seen alsovat 3 in lig. '1, one of said bearingsin g. 1 not being fully visible.- 4 4 4, in fig. 1, are-oblong perforated slots punched from the inside, and in rows, breaking joints with each other, the edges projectingoutward, for the purpose of holding the straw more firmly. 55 5 5. in g. 1, are holes in the vibrating lever G1, seen also in g. 2. y

Tlie cutting-box and frame A should ho made from tento fifteen inches wide, and four feet long; The frame should be about two feet two inches high. The rollers E E should be made of goed sheet iron. The oblong slots 44 4 shouldbe punched. before the sheet iron is formed in a roller. The shafts oftherollcrs should be made of three-quarter or one-inch round iron. The -heads'may be madeof'wood or iron, and secured to the shaft. The sheet iron is secured to the heads. The ratchets F F, pawls H1 and I, connectinglrod L, and clamp Z, and vibrating lever G, should all be made of cast iron. The bar B should be made of east iron. It isA not necessary that the slot S should be set hack of the bar, as vthe bar may be straight, and the slot S may be on a line with the hack of' the bar if desired. The cap G may be made of wood or thick sheet iron. The springs H H should be made of good hickory, ash, or oak timber. Said cap and springs are intended to press down the/top roller, and the front of thecap to press down the straw 'in front of the roller. The knife-"C should be made of good east steel, and well secured to tbe arms V V, which arel cast with hubs and secured on the shaft 2. Said shaft 2 should be made of one and a quarter inch roundiron. The pieces D D'sliould be,cast with the slots and hole, as seen at fig. 4. The ily-Wheel should be cast iron, as also the cam 1M, which may be castrfast to theviy-wheel, or secured from turning on the shaft, by means of a pin or scrcws,'or may be'keyed on the shaft. 1 f

' Operation.

It will be seen that by placing straw` in the box A, and inserting it between the rollers E E, by applying power to the wheel O, the pinion P, shaft 2, and cam M, are caused to revolve, operating the vibrating lever G1, by means of the ro'd L. AThe pawls H1 and I operating'on the ratchets F F, the rollers E E are turned,

and the straw drawn toward the knife, and being' supported by the barv B, and held down by'the front side of the cap G, is cut by the knife C at each revolution of the ily-wheel N. The length of the cut may be varied. By placing the cam-rod L in the lioles 5 5 5 5, further from the cen'tre of lever G, a shorter cut is obtained. Y We do not claim a. movable or adjustable bar, neither do we claim arevolving spiral knife, nor the feedrollers, as We are aware that they have all been used in different forms by other persons but, V i

What we do claim as our invention', and desire to secure by Letters Patent, is v v 1. The combination of the side pieces D D, constructed as described, containing the bearings for the cutting-mechanism, the shearing-bar B, with square faces, and the spirally bladed knife Cyarranged substan- 4 tially as described. v

2. The 'combination of the 'perforated rollers E, ratchet-wheels F, pawls H1, I, and R, adjustable oscil' lating arm G1, eccentric-rod L, `and eccentric M, respectively constructed and arranged substantially as set forth. 3. The arrangement of the cap G, rollers EE, covers Q, side pieces D D, knife C, and the driving and the fcedmechanism, constructed and combined substantially as set forth. l 4

4. Thevfeederollers E, 'when constructed from sheet metal, and punched from the inside, forming projections as shown, for feeding the ,straw to the knife. i l

5. lThe metallic side pieces D'D, constructed as described, in coxnbination-witb the bar B, knife C; feedfA rollers E E, arranged substantially asset forth.

6. The combination of the eccentric M on the knife-shaft, eccentricirod'L, and oscillating aru'l G, when the latter are so arranged as to regulate the cut by adjusting the point ofattachment, substantiallylin the manner set forth.Y Y
