Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed August 30, 1904. Serial No. 222,768.

To aZZ whom it may concern:

Be it known that I, ARTHUR M. SHEAKLEY, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Fiber-Cutting Machines; and I do declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in machines used in cutting Manila fiber or old Manila rope into suitable lengths to be prepared for use in making mortar for plastering purposes and the like; and it consists in the peculiar and effective construction and relative arrangements of parts herein specified.

My object is to produce a machine which will quickly and effectually out the fiber into suitable lengths and convey the same to a suitable picking or other machine, and I accomplish said object by the construction hereinafter fully described, and particularly pointed out in the claims appended.

Referring now to the drawings, Figure 1 represents a top plan .viewof my improved machine. Fig. 2 is a sectional view of a feeder and cutter. Fig. 3 is a side elevation of a shaft-box. carrier. Fig. 4 is a side elevation of a shaft-box. Fig. 5 is an end elevation of same. Fig. 6 is a front elevation of a cutterblade. Fig. 7 is a side elevation of a cutterwheel. Fig. 8 is a sectional view of a shaftbox holder. Fig. 9 is a side elevation of my improved fiber-cutting machine. Fig. 10 is a sectional view of a feedroller. Fig. 11 is a longitudinal sectional view, on a reduced scale, of the conveyer and conveyer-box.

Similar numerals of reference indicate corresponding parts in the several views.

On suitable upright supporting-beams 1 are fastened beams 2 and 2. Across the upper sides of said beams 2 and 2 are fastened beams 3, 4, 4, 5, 6, 7, and 8 at any desired points. On the beams 3 and 4 and 4 is fastened an iron plate 9, which plate is provided with a slot 10, said slot having an upwardly-projecting rim 11. Over one end of said slot is a dust-flue 12, as shown in section in Fig. 1. A

shaft 13 is mountedon said plate 9 and extends across the slot 10 at the center thereof.

On said shaft is rigidly attached a cutterwheel 14, provided with arms 15, which wheel rotates in the slot 10. On each of said arms are two outwardly-projecting lugs 16, forming component parts of said arms. On said lugs knives 17 are bolted or otherwise fastened, said knives extending downward from said lugs. Said lugs are a sufiicient distance apart and extend a considerable-distance from the arms 15, thus leaving a space 18 between the knives and the arms. Beneath each lug 16 set-screws 19 extend through the arms and into the knives 17 and are adapted to be used to adjust the position of said vknives.

20 is a feed-box resting on the beams 5, 6, and 7, which feed-box has a narrow portion 21, which opens into the slot 10 just in front of the shaft 13.

The shaft 13 extends across the beam 5 and is seated in a bearing 22 on the beam 6. At the end of said shaft-which extends over the beam 6 is a clutch mechanism 23, operated by means of a lever 23, at the end of which clutch mechanism is a bevel-gear 24, intermeshing with two bevel-gears 25 and 26, attached to shafts 27 and 28, respectively,which shafts are journaled on the beam 7. On the shaft 28 is a sprocket-wheel 29, on which is a linked belt 30, connecting it to a larger sprocket-wheel 31, which wheel is on a shaft 32, journaled on the under sides of the beams 2 2. On one end of the shaft 32 is a small sprocket-wheel 33. A link belt 34 connects the sprocket-wheel 33 to a sprocket-wheel 36, located on the end of a shaft 37, which shaft is journaled on the plate 9. On the shaft 37 is suitably arranged a roller 38, said roller being located in an iron block 47, secured on the plate 9 just under the part 21, said roller extending upward to a level with the floor of the feed-box 20. On theend of the shaft 27 is a sprocket-wheel 39. A link belt 40 connects said sprocket-wheel 39 to a sprocketwheel 41, fastened on a shaft 42, which shaft is journaled on the plate 9. On said shaft is a corrugated roller 43, which roller fits between the sides of the narrow portion 21 of the feed-box 20 just over the roller 38. Said roller is square-seated on the shaft 42, said square portion in the roller being tapered from the ends to the center, as shown in Fig. 10. On the side of the roller 43 which is farthest from the sprocket-wheel 41 the shaft 42 is seated in a box 44 having guide-arms 45,

which box fits between two arms 46, forming component parts of a base-plate 47, which base-plate forms a component part of the block 47. Said arms curve slightly toward the roller 43. On the free end of said shaft 42 a weight 43 is suspended from said shaft by means of a rope 49. Near the sprocketwheel 41 the shaft 42 is seated in a box 50, which box is pivotally mounted between the jaws 51 of a Y-shaped standard 52.

A plate 53 is fastened onto the beam 4 and extends upward in front of the roller 43, in which plate is a feed-opening directly in front of the roller 43. A cast-iron plate 54 is bolted or otherwise fastened onto the plate 53 and has a similar coinciding feed-opening. On the plate 54 iswelded a steel cutting-blade 55, which cutting-blade has a similar coinciding feedopening, as has the plate 54. This blade 55 is so arranged as to coact with the knives 17 as the wheel 14 revolves.

Under the slot 10 is a conveyer-box 56, open at one end and closed at the other. Near the open end are secured two shafts 58 and 58, arranged one above the other, and near the closed end is secured a shaft 57, on which shaft are secured sprocket-wheels 59. On the shaft 58 are secured sprocket-wheels 60, and on the shaft 58 are secured smooth pulleys 60. Link belts 61 operatively connect said sprocket-wheels and pulleys. On said linli belts are rigidly attached slats 62, which drag on the floor of the conveyer-box 56. On the shaft 58 outside the box 56 is fastened a pulley 63, on which is a belt 64, connecting said pulley to a similar pulley 65 on a shaft 66, which shaft is journaled on the beams 5 and 6, on the other end of which shaft is a bevelgear 67 which intermeshes with a bevel-gear 68, which last-named gear is rigidly attached onto the shaft .27.

The operation is as follows: Any suitable motive power is applied to the shaft 13, which revolves the wheel 14. The clutch device 23 is thrown together by means of the lever 23, as is apparent. This starts in motion the feed- rollers 43 and 38 and also the conveying apparatus in the conveyer-box 56. The rope or other material is then fed between the rollers 43 and 58 and is cut into the desired lengths by means of the knives 17 and the cutter-blade 55. and then it falls onto the conveyer below said wheel and is conveyed to any point desired. The shaft 42, being pivotally mounted, allows large or small ropes to pass beneath the roller 43, and said roller, being pivotally mounted, as shown in Fig. 10, always stays in a position relative to the size of the material passing under it. The space 18 allows the cut material to fall down onto the conveyer and not choke up around the knives. The dust-chute 12 is to convey dust, &c., to outside of the building. The set-screws 19 are for the purpose of adgusting the knives l7 and keeping them so that they will always pass in close contact with the blade 55. This construction is particularly advantageous in view of the fact that the knives are not always true when made and are inclined to bend one way or the other; but by use of the set-screw they may be adjusted to the required position.

The purpose of having a slight curve in the standards 46 is to prevent the box 44 from binding as. it moves up or down between said standards.

The advantage of having two shafts at the open end of the conveyer 56 is to permit the slats 62 to travel vertically for a short distance, thus allowing all material thereon to drop off and not carry it back into the conveyer again. A suitable box or other covering may be placed over the wheel 14 when the same is in motion, thus preventing it from throwing any of the cut material outside of the machine.

Many changes may be made in my invention without departing from the spirit thereof. Hence I consider myself entitled to all forms of the invention as fairly fall within the scope of my claims.

Having thus described my invention, what I claim as new and useful, and desire to se cure by Letters Patent, is-
