' Application filed March 15, 1926. Serial No. 94,632.
This invention relates to a machine and process for the reduction to raw fiber for spinning, weavingand converting into merchandise, the stalk or leaf of fibrousplants, and the foremost object of the machine is in the provision of certain novel expediences for the complete separation of the bark, chaff and other foreign substances from the fibrous filaments ofthe plant afterthorough dehydration of the latter, during which time the plant is subjected to a continuous .air draught, to insure a 'positively' clean condition of the fiber upon emerging from the machine;
' The invention further aims among its objects to increase materially the. percentage of raw fiber extracted from plants while in a green stage, concurrent with the obvious saving'in material, freight, and other eX- pense incident to the production of fiber in this manner. I
till another object of the invention resides in the novel assembly of rollers whereby the commodity may be conducted through the machine on substantially a horizontal plane, during its subjugation to'the process of bark elimination, and by being so conducted, any disruptive bending, folding, or twisting action is avoided which may prove detrimental. to the quality or tensile. strength of the product, rendering it unfit for ultimate use. 1
Yet another object of the invention resides, especially in the decortication of Letchguilla, Mcgue, and similar fibrous plant leaves, a means in the form of yieldable rollers, to avoid injury to the extracted fiber strands, by preventing the flattening or crushing into an oval shape the natural tubular or cylindrical fiber more prevalent in this type of plant, and in addition, to establish an equally effective holding and decorticating *means for the leaves of nonuniform size. v
With these and other novel objects and-advantages in view, the invention has particu lar reference to its salient features of-con struction and operation of parts which will be manifested in the course of the following detail description and illustrated inthe appended drawings, wherein:
Figure 1 represents aside elevationalview of the machine illustrating the means'for im iarting reverse movement to a multiplie ity of brush cylinders disposed staggered relationship on the machine.
'Figure 2 is a side elevational view of the opposite side of the machine.
Figure 3 represents an 'end elevational view of the machine.
Figure t represents a fragmentary end elevation in longitudinal cross-section,
' from the machine.
, As hereinbefore mentioned and defined as being included among the prime objects of the present invention, it is especially pointed out in proceeding further that in traveling through the machine, the plant maintains strictly a horizontal plane throughout, and
no bending, buckling or disruptive action aside fromthis plane is required to free the woody part of the plant from the'fiber proper, thus enabling the finished product to emerge from the machine positively free from bark, chaff, and without bends, waves, or undulations created throughits passage about irregularly surfaced rollers.
Now, in proceeding more in detail with the drawings, particular attention" is directed to Figures 1 and 2, depicting opposite side elevations of a machine, constructed according to the invention, and in which is shown a frame 1, supported upon legs 2, spaced apart.
Along the frame 1, a multiplicity of rollers are provided,'whi ch 'are divided into units containingpreferably two'of such rollers and a cylinder brush, more specifically referred to hereinafter as cylinders. These units aresituated both above and below the "horizontal plane of the frame 1,'allowing their contacting surfaces to aline with the plane surface of the frame. Theunits situ ated abovethis plane maintained IIIPOSI."
tive relationship by having their ends mounted in adjustableend bearingsfi, a detail example of which is clearly depicted in Figure 6, and defined later. The lower rollers, as apparent in Figure 4: have their shafts extended through spaced plates 4, on the inner sides of the frame 1, and provided with suitable ball bearings, the latter not being shown.
Embodied in each of the units above the surface of the frame 1 are a pair of rollers 5, suitably jacketed with rubber or with a material having equal resiliency, and whose ends are provided with brass or equivalent bearings 6, having vertical movement under tension being imposed upon the bearings 6 by springs 7.. against which look set screws 8 are adapted to bear, as in the detail view of the bearings shown in Figure 6. Intermediate each of therollers 5, a brush cylinder 9 is rotatably mounted, which is provided with cutters 10, spaced radially about the body thereof and extending from end to end as shown in Figure 9. This brush cylinder is likewise mounted in the end bearings 3, at approximately the center thereof. Reference to the Figure will disclose that directly below, and in contacting engagement with the circular line of travel of the cutters 10 of the cylinder 9, a baflie plate 11 is provided which is of substantially T shape in'crosssection, and in the cross member thereof, a yieldable pad or facing 12 1s caulked as particularly shown in F lgures 7 and 8, and against which the cylinder cutterslO contact, during rotation thereof.
In vertical alinement with each of the rubber surfaced rollers '5, see Figure 4, a
steel roller 13 is rotatably mounted to slightly contact therewith, such point of contact being, as mentioned previously, in alinement with the surface of the frame 1. These lower units each include likewise a brush cylinder 9, and while the bafiie plate 11 is inverted, or reverse to its position in the upper units, the purpose thereof is the same. The plates 11 have facilities for their proper adjustment with respect to the cylinders 9, as obviously disclosed in Figure Al, such adjustment being accomplished in the lower plates by set screws 14 through brackets 15 into which the ends of the plates 11 are thrust, while the upper plates are equipped with end flanges 16, through which a bolt 1'? protrudes from the frame 1. It is preferred that the plates 11 nearest the feeding end of the machine be so adjusted as to leave a slight space between its point of contact with the circular path of the cutters 10 of the cylinder 9, and the distance'between each remainingassembly be successively diminished by adjustments in accordance with the diminishing bulk of commodity as it travels through the machine.
Therubber jacketed rollers 5, aside from truding end of each of the shafts of the rollers 13, and a like number of cylinder worm gears 19, mounted upon a longitudinal shaft 20, is provided to transmit rotation to the rollers 13, from the power applied to rotate the brush cylinders 9. A reduction to the minimum of friction is established by the application of a worm drive such as illus- 'trated, however, alterations may be made in this arrangement to accord with. circumstances of different scope. The shaft 20, it will be observed especially in Figure 2 is mounted in bearings 2-1 affixed to the sides of the frame 1, and its end protrudes beyond the end of the frame, where it carries a sprocket, about which a chain 22 is mounted and surrounds a similar sprocket 23, situated upon a shaft 24, the latter extending longitudinally beneath the machine the full length thereof; 'Now, referring to the end View of the machine in Figure '3, the power receiving end of the shaft 24: is shown as carrying a beveli 25, which enmeshes a similar gear 26, situ ated upon a shaft 27, laterally extending across the machine and supported in bearings 28, afiixed to the legs 2; This shaft27 likcwise carries on one end, a drive wheel 29, and an idle wheel 30, in addition to a wneel 31 for the purpose of transmitting power to the brush cylinders 9, which arrangement will be more concisely set forth hereinafter. On the opposite end of shaft 27, a wheel is mounted and is likewise adapted to impart rotation to the brush cy inders 9, to balance the power applied thereto, and to avoid any possibilities of said draft. Particular attention is directed to the iner inwhich motion is imparted to the linders 9, to establish a constant forward movement of the stalksthrou hout themachine. and in this regard, r 'ence is directed to Figures 1 and 2, in which a plu rality of pulleys are shown, one of which is situated upon the protruding shafts of each of the cylinders 9. Now, i alternate cylinders are situated above and be low the line of linen El of theplant stallrs as they proceed through the machine, the pcculiar alternate mounting of the 'belt 342 on the pulleys .33, transmitsmotion to each of the pulleys from the wheel 39, to'move the said cylinders'in reverse directions with respect to one another, but at all times accordance with the movement of the pla Referring now to the means for extracting and dispensing with the bark and woody refuse of the plant after its disentegration, resulting from its passage through the machine, a plurality of hoods 35 is provided, one of which is adapted to be situated directly above each of the plates 11, and an apron 36 is mounted below the machine as shown, to include all of the cylinders 9. Although illustrating only three hoods, it is of course obvious that as many may be applied as required to accommodate all of the Said cylinders. For the purpose of creating a draught through the machine, to insure thorough cleaning of the bark and chafi' from the fiber as it travels therethrough, a large blower 37 is aiiixed to one of the legs 2, or at another convenient point, and which is operated through a belt 38, surrounding a pulley 39 disposed upon the longitudinal shaft 2 1. See Figure 5. series of pipes 40, extend upwardly from the hoods 35, and are directed to the blower 37 and a similar communication from the apron 36 is established through a pipe 41 therebeneath. Through this arrangement of pipes, the blower 37 is enabled to maintain a dual suction from above and below the assembly of rollers and carry off all substance extracted from the fiber during the process of disintegration, such suction being augmented by the fanning action of the brushes 9, while in high speed of rotation.
It has been found to be of practical value to establish in the machine, an arrangement whereby the masses of fiber may be divided into bunches, of a predetermined size upon issuing from the machine which may greatly aid in the handling of the product. An example of this arrangement is depicted in Figure 10, and which is composed of a num ber of spaced, vertically disposed. wires l2, which depend from the plate 11 nearest the issuing end of the machine, and secured to a cross member 13, which is, in turn secured at either end to the sides of the frame 1. The fiber in passing from the machine, must pass between the wires 42, and be thereby separated into bunches the width of the space between the wires. An example of the manner in which this arrangement is applied in operative position on the machine may be seen in the longitudinal cross-section in Figure 5.
While the machine and process disclosed is not restricted necessarily to the producing, cleaning and development of fiber in a dehydrated state, such a condition is of course more desirable, since the plant is obviously more susceptible to disintegration, and thus yields the fiber more readily when passed through the machine in addition to the considerable saving in transportation costs from the point of harvest. With this in view, the plants are harvested and perforated by a suitable machine to aid in the expulsion of sap and moisture, after which it-is dried in the sun, kiln dried, or by other artificial processes. hen this is done, the plants are in condition for subjection to the cleaning process by the machine. a
It will be seen in the drawings, Figure 2 that'a carrier belt 1 1, of a material applicable to the purpose, is provided, which is directed over a roller 15, adjacent to the first set of rollers 5 and 13. The plants are placed upon this belt id in such a manner that the tops thereof will first be received between the rollers 5 and 13, and travel in this position as indicated by the arrows in Figures 1 and 2 throughout the machine.
Notice will be taken in Figure 1, that the first two sets of rollers 5 and 13 are provided with interineshing gears 46, and as the remaining upper rollers 5 are idle, as aforesaid, power is supplied to these first rollers from A the worm drive on the opposite end of the shafts of the rollers 13, to insure the proper reception of the plants.
The non-resilient rollers 13 are adapted in practical use of the machine, to travel at the rate of approximately 250 R. P. M., while the brushes 9 rotate at a higher velocity of about 2500 R. P. M. This arrangement provides for the passage of a commodity between the rollers at a rate of approximately 150 linear feet per minute. Due to the resiliency obtained in the rollers 5 and 13, both through the surrounding jacket of the former, as well as through the yieldable hearing 6, the pressure imposed upon the plant by these rollers during its passage therebetween is only of such extent as to shatter and break the woody part of the plant, and does not in any respect injure the fiber strands or deteriorate the tensile strength thereof. During its passage between the rollers, the plant must pass across the plates 11, which, as mentioned previously, are equipped with yieldable pads 12. In thus passing, the revolving blades 10 of the brush cylinders 9 swipingl'y contact with the plants. against this yieldable plate and toward the direction of travel of the said plants, thus imparting to the fiber strands apolishing, rather than a scraping action, and simultaneously, through the draught created by the velocity of its motion, the cylinders are instrumental in imparting a vibratory efiect upon the disintegrated plant, thereby aiding 1 materially in releasing and removing therefrom, the loose and clinging chaff, in addition to the air forces drawn through the machine by the blower 37.
Thus, the fiber passes entirely through each of the units and ultimately emerges from the last set of rollers in a very short period of time, and in a clean and polished condition positively free from chaff, bark or substance of any foreign character, after which it is conveyed onto the endless belt 47, shown in Figures 2 and 4-, by which it is transported to a baler or other means of preparing for shipment, in a raw condition for ultimate weaving and converting into merchandise.
It will be understood of course, that while the machine has been specifically described as to its details of construction and use, certain minor changes and modifications as to its various structural elements and purpose may be resorted to if desired, without departing from the spirit or intent of the invention, provided such alterations are within the scope and meaning of the following claims therefor.
