To all whom it 'may concern:

Be it known that I, ANGEL Pons, a subject of the King of Spain, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Fiber- Cleaning l/faehines, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure l is a side elevation of the machine embodying the principles of my invention; Fig. 2 a front elevation with the feeding table removed; Fig. 3 a plan view; Fig. 4 a detail section of the rim of a carrying wheel and its accompanying platen segment; Fig. 5 a view of the face of a carrying wheel; Fig. 6 a face view of the corrugated stripping blade held in posit-ion in front of the scraper; and Fig. 7 a sectional view showing the way in which the stripping blades are attached to the rim of the cleaning wheel.

My invention relates to machines for cleaning fibers of plants, and more particularly to machines for removing the lieshy integument of leaves such as the South American aloe (Ag/aoc Ssalz'cnscs) from the ribs and fibers thereof.

My invention consists of certain arrangements of parts and details of construction which will be hereinafter more definitely pointed out in the claims, and the object thereof is to provide a fiber cleaning apparatus which will completely remove the tissue between the ribs or fibers of these leaves; which may be operated with a minimum of hand-labor; and which is simple in construction and easily adjusted to suit special requirements.

T o this end my invention generally, contemplates the use of a series of cleaning blades or beaters, held upon revolving wheels, and carriers for moving the leaves across the path of said blades, in such manner that the entire surface of a leaf will be presented for cleaning.

.ln the accompanying drawings, wherein like letters bear reference to like parts, A designates any suitable base or platform on which my apparatus is to be mounted, and B the supporting frame of the machine.

Fig. 3 shows most clearly the relative arrangement of the apparatus and of its cleaning wheels and leaf-carrying wheels,

there being two oppositely disposed cleaning wheels and a carrier wheel for each with a transferring carrier wheel between the two main carrier wheels.

Beginning at the front end of the machine, C designates a table or support from which the middle portions of the leaves are fed edgewise to the feeding wheels D D, which are mounted on a shaft D. These wheels are toothed, spurred or otherwise adapted to engage with a leaf and move it forward to the first of the carriers. The forward end of the table is provided with downwardly curved arms c c which project under the feed wheels D. Thus, in the rotation of the wheels D, (whose driving mechanism will be later described) the middle of the leaf to be treated is drawn in between the feed wheels and the arms c, the ends of the leaf hanging downwardly on each side and one end being in a position where it may engage a guide-plate /L and be guided into alinement with the curved opening between thecleaning wheel Gr and a breast plate in opposition thereto.

E designates oneI of the main carrier wheels which is designed to move the leaf transversely across the moving face of the cleaning wheel G. This wheel E has a central circumferential rib c; parallel circumferential grooves being formed on each side of said rib, and two rows of outer teeth or spurs c c which extend radially from the periphery of the wheel at the edges thereof, these teeth being preferably inclined in the direction of the wheel movement. The carrier wheel E is mounted on a shaft ll which in turn is connected by a sprocket wheel and chain to the main driving gear, as will be hereinafter described.

The shaft D which bears the feed wheels D D, is mounted on a platen segment F which is pivoted at its rear -end to one of a pair of spring-pressed segments F2 F which tit over the upper are of the wheel E. The segment F and the other platen segments are supported from a longitudinal skeleton frame R by sliding bolts f and are held down toward the carrier wheel, or on the face thereof, according to the adjustment of the bolts f by coil springs f. The position of the platen with respect to the face of the carrier wheel is regulated by means of nuts Z screwed on the upper ends of the bolts f and bearing against the. frame R. Platen segments may be permitted to touch the carrier wheel or they may be adjusted a suitable distance therefrom. The variation in the position of the platen segments will vary the pressure of the springs f thereon.

The platen segments F F 2 F 3 are arranged upon the carrier wheel and the said wheel moves the leaves under the jointed platen or gripping device thus formed. The carrier wheel and the platen segments thus form a gripping device, one part of which may be rotated, the other part being held against a rotative movement and being permitted to have only a radial or outward movement away from the carrier wheel. The platen segments are in cross section of the form shown in Fig'. 4. The inner faces thereof, that is to say, the faces which co-act with the face of the carrier wheel are formed with the two outwardly eX- tending longitudinal ribs f2, between which is formed a longitudinal groove to receive the central rib e of the carrier wheel. The outer margin f3 of the segments projects in a curve beyond the line of the outside row of teeth e on the carrier wheel. The urpose of the ribs f2 is to press the middle of a leaf down firmly onto the carrier wheel E and in conjunction with the central rib e of the carrier wheel and its toothed edges e, to hold said leaf against endwise movement under the action of the cleaning wheels. The overhanging curve of the outside margin of the platen segments is to give a sharper downward bend to that end of the leaf which is to be acted on. There are three platen segments shown, but it will, of

course, be understood that I may use any desired number. These platen segments are hinged or pivoted together at their adjoining ends, the ends of the platen overlapping to form the hinge and the overlapped parts being rounded off to permit the platens to have a free pivotal movement and also to permit the leaves to pass readily from under one platen segment to the neXt segment without any liability of damaging the fiber. By pivoting the platen segments or sections together at their adjoining ends they may yield and may be moved outwardly away from the face of the carrier wheel as the leaves are carried under and past said platen segments by the carrier wheel. It will thus be seen that the holding device is given an undulating movement toward and away from the carrier wheel. This is of great importance as it enables it to work on leaves of varying thicknesses and to pass said leaves through the machine rapidly one after the other. It will be understood that by adjusting the nuts on the bolts the platen segment-s may be properly placed with respect to the carrier wheel face and the pressure of the springs on the platen segments may be varied by thus varying the position of the platen segments; and the outward movement of the platen segments under the influence of the leaves passing under said sections may be regulated by vertically or outwardly adjusting the bolts carrying said segments. By providing a jointed or sectional platen I am enabled to feed leaves into the carrier, the plurality of sections admitting of play to suit the varying thicknesses of leaves, several of which may be carried through the machine at the same time. Thus the rapidity of the machine and its effectiveness are materially increased.l

It will be noted that by means of the adjustable bolts connected to t-he platen sections, said sections may be so adjusted as to be out of contact with the carrier wheel. By this means there will be no friction between the carrier wheel and the platen when no leaves are held between the said two parts. By overlapping the ends of the platen sections and pivoting said sections together', the platens present a practically continuous gripping surface to the carrier wheel; and by rounding olf the lower corners of the overlapped portions of the platen sections, as shown in Fig. l, the leaf will not be obstructed in its passage under the platen sections and the joints between the connected sections.

It will be noted that the grooved and ribbed surface of the platen sections interlock with the corresponding grooves and ribs on the carrier wheel face and thus grip the leaves in such manner that they are firmly held to withstand the action of the cleaning wheels. The teeth on the outer edges of the carrier wheel assistin moving the leaf under the platen sections.

It will be noted that the platen segments may be held slightly away from the carrier wheels so that there will be an approximate sliding engagement, that is to say, the carrier wheels will move or slide along under the platen segments and said segments 'will be held against movement except that they will move outwardly or away from the carrier wheel as the leaves pass under them.

It will be noted on reference to Fig. l that one of the springs f is arranged directly in front of each of the cleaning wheels (which will be hereinafter described) so that said spring will serve to firmly hold the leaf while it is being acted upon by the adjoining cleaning wheel.

G is a cleaning wheel mounted on a shaft G, for scraping, stripping or cleaning one end of a leaf. Its plane of rotation is at right angles to that of the carrier wheel E and it is located forward of the shaft E. As arranged, the end of the leaf is carried across the face of the scraper wheel G and at the same time in a direction opposite to the rotation of said wheel. The rim G2 of the cleaning wheel is provided with outwardly projecting radial ribs g2 which extend transversely of the rim and to which the stripping blades and scraping blades are bolted. rI`he stripping blades I, which are preferably made of brass, are of the peculiar' form shown in Fig. 6. They are corrugated with a rounded edge and act to compress the middle or fleshy part of the leaf so that the scrapers I may act more easily to clean the leaf. The scraping blades are made wedge shape in cross section and are held between the stripping blades and the ribs g2 by suitable bolts which pass through slots formed in the stripping and scraping blades and through apertures in said ribs. The scraper blades I may be adjusted by means of bolts gi which pass through the arm g2 and bear against the inner edge of said blades.

II is a curved bed or breast plate of brass or other material not liable to become rusted or corroded by the moisture from the pulp scraped from the leaves. It is curved to conform to the circumference of wheel G; and it is supported on a bed H which forms part of a fran'iing plate B. 0n either side of the wheel G are the frame plates BL whose edges conform to the curve of the bed plate Il and are separated therefrom by a space of a suitable width.

The operation of the machine so far described is as follows :-The leaf is placed with its middle on the table 0,' the two ends of the leaf hanging downwardly from said table with one end on the side toward the wheel G. The leaf is then moved edgewise by hand into engagement with the feed wheels D I) which move the leaf inwardly under the platen segments 7" until it is lalight by the spurs or teeth on the edges of the revolving carrier wheel E. IVhile this is being done one depending portion of the leaf engages the guide plate h and is guided into alinement with the curved opening between the breast plate or cleaning bed II and the frame plate B2. As the carrier wheel E rotates it carries one end of the leaf across the face of the rotating wheel G and this wheel in its rotation draws the strippers I and scrapers I down the half length of the leaf, thus cleaning that half of the leaf of its coating and the fleshy web or matter between the fibers. The peculiar form of stripping blades and scrapers or beaters will be hereinafter described. The leaf has now been cleaned for one half its length and it is necessary that the other part thereof be cleaned. For this purpose I provide the machine with another cleaning wheel N oppositely disposed to the wheel Gr; and a carrying wheel L for moving the leaf across the surface of the cleaning wheel. Before moving the leaf to the carrying wheel L, for presentation of its uucleaned surface to the second cleaning wheel, it must be shifted somewhat and so that the part of the leaf which has before been held by the carrier wheel and its co-acting platen and was, therefore, untouched by the scraping or cleaning wheels, may be acted upon. In order to thus move it to the new carrier and shift the grip on the leaf to the cleaned part, I provide the intermediate spurred or toothed transfer wheels J and J mounted on a transverse shaft J* whose driving gears will be hereinafter described. The transfer wheels are off-set at one side out of alinement with the carrier wheel It) so as to take hold of that portion of the leaf previously scraped by the cleaning wheel Gr. The sec ond carrier wheel is out of line with the first. carrier wheel, its vertical plane, however, being parallel with the vertical plane of the said first carrier wheel N. rThe transfer wheel J is arranged between the carrier wheels E and N, said wheel being out of line with the said carrier wheels, its vertical plane being parallel with the vertical planes of said carrier wheels. The transfer wheels J and J are spaced apart from each other and are of somewhat di'tterent characters, the inner one J being ribbed on its circumference lilte the carrier wheels, that .is to say, it is substantially of the same shape in transverse section as the said carrier wheels. The outer carrier wheel J is located adjacent the outer side of the second carrier wheel N and is simply provided with radial teeth. These wheels rotate in a direction reverse to that of the rotation of the carrier wheel E; and are of such size and are so placed as to bridge the space between the two wheels ll and L, as shown clearly in Fig. l. Opposite these wheels are platen segments J2 and J, these segments being of the same character as those already described with respect to carrier wheel E. These platen segments are supported and pressed toward the transfer wheels by spring Bolts y" connect the segments with the rigid frame work of the machine, said bolts being surrounded by the springs; and by adjusting the nuts ou the ends of the bolts j the platen segments may be adjusted toward and from the transfer wheels and the pressure of the springs on the segments be increased or diminished as desired. It will be noted that the segmentl J2 extends upwardly on the circumference of the wheel J toward the front end of tht` machine, that is, toward the carrier wheel IC somewhat farther than the segment J". lt will also be noted that the rear end of the segment, J3 extends upwardly ou the circumference of the rear carrier wheel L substantially as high as the forward end of the segment J2. The circumferences of the transfer wheels at the upper ends of the segments J- and J3 are substantially in a transverse line with the circumferences of the carrier llO cleaning bed H. 'i its lower end to the upper end of the platen wheels at those points, for a purpose which will clearly appear hereinafter in the description of the general operation of the machine.

Two guide rods Y2 and K2 extend downwardly from the upper end of the breast or The rod K2 is secured at segment J2 while the rod K2 is secured to the forward end of the segment J 2. By means of these rods the depending cleaned portion of the leaf as it emerges from the cleaning bed is guided to the space between the transfer wheels and their co-acting platens. Because of the location of the transfer wheel J with respect to the carrier wheel E the cleaned portion of the leaf will be delivered to the said wheel and its platen before the leaf is released from the carrier wheel E and its platen; and the transfer Wheel J and its platen J3 will receive the leaf, or the cleaned portion thereof, when said leaf is near the lower end of the platen of the car,- rier wheel E. By this means the leaf will be gripped at two points in its length when it is released from the carrier wheel E and the fiber extending between the transfer wheels will be held in a flat or substantially horizontal position, and will be maintained in this position during` its presentation to the second carrier wheel and its platen. It will be noted that the transfer wheels are arranged on each side of the second carrier wheel and that the second carrier wheel and its co-acting platen extends into the space between said transfer wheels, the transfer wheels and the said second carrier wheel being arranged in parallel vertical planes.

The second carrier wheel L is of the same construction as .the carrier wheel E and need not, therefore, be specifically described. This second carrier wheel also rotates in the same direction as wheel E and in a direction opposite to the rotation of the transfer wheels. This wheel is mounted on the shaft L', which will be hereinafter described as the main driving shaft of the machine. Above the carrier wheel L are arranged the platen segments M M and M2 which are of the same construction as the segments F F2 and F 3 arranged above the carrier wheel E and are hinged together at their adjoining ends in the same manner as the said platen segments F.

The cleaning wheel N heretofore referred to is mounted on a shaft N to rotate at right angles to the carrier wheel N on the opposite side thereof from the cleaning wheel G so that it is adapted to operate on the uncleaned portion of the leaf. This wheel is provided with a. cleaning bed and with cleaning blades and stripping blades I and I of the same construction as those carried by the cleaning wheel G. The second cleaning wheel N is somewhat smaller than the wheel G. The

bearings of the cleaning wheels are provided with screws g4l mt which are parallel to the horizontal plane of the journal boxes and serve to take the shearing strains off the bolts which hold the journal boxes to the frame plates. By setting up these bolt-s the cleaning wheels may be adjusted and thus rigidly held in proper position with respect to the cleaning bed or breast plate against which they work.

It will, of course, be understood that any desired system of gearing for driving the apparatus may be employed, the system shown, however, is very desirable and has given very satisfactory results.

In the apparatus, as shown, the shaft L', as heretofore stated, is the main driving shaft from which connections are made to the shafts of the other carrier wheel and the transfer wheels. This shaft L carries the worin wheel L2 which is engaged by worms 02 on a` shaft O, this latter shaft having a belt wheel O which is driven from any suitable source of power. @n the opposite end of the shaft L from the worm wheel L2 is secured a sprocket wheel L3 over which a sprocket chain Z2 runs to a sprocket wheel P on an intermediate shaft p, this latter shaft being mounted in a vertical frame post S. The shaft 79 also carries a gear P2 which engages with a pinion P on the shaft J4 which carries the intermediate or-transfer wheels J and J. This pinion is so proportioned to its engaging gear P2 that the circumferences of the transfer wheels will move at the same speed as the circumferences of the main carrier wheels. The object of this is that the leaf will be moved at a uniform speed when it is simultaneously engaged by the carrier wheels and the transfer wheel. The shaft J 4 carries a sprocket J5 on the opposite end thereof from the pinion P; and from this sprocket a chain jf' runs to a small sprocket on the feed shaft D thereby driving said shaft in the proper direction to feed the leaf to the carrier wheel E. The shaft E of the carrier wheel E is provided with a sprocket wheel E2 from which the sprocket e2 runs to a sprocket wheel L4 on the main drive shaft L. It will, of course, be understood that these sprocket wheels are so proportioned that the two carrier wheels are driven at the same speed; and the drive connection is so arranged that said wheels rotate in the same direction.

The cleaning wheels G and N are preferably driven independently from belt wheels G5 N5 mounted on the shafts of said wheels. These wheels are intended to revolve at a speed of about four hundred and fifty revolutions a minute, while the carrier wheels make about twelve revolutions a minute.

The frame of my machine I preferably form of plates bolted together solidly as shown and supported by any suitable bed. A skeleton frame R. hereinbefore referred to, is supported by the post S substantially midway between its ends and by posts li secured to the main fame of the machine.

The general operation of the machine is as follows The leaf to be operated on is laid across the table C and is pushed forward, edgewise, by the operator to the feeding wheels D which deliver it to the carrier wheel E by which it is carried upwardunder the platen segment F. As the carrier moves the leaf across the face of the first cleaning wheel the leaf is cleaned from a point near its middle to one end. lhen the leaf reaches the intermediate carriers, or t 'ansfer wheels, the cleaned portion thereof is gripped by said transfer wheels and their platens and carried downward until it is released from the platens of the first carrier wheel. It is then carried upward by said transfer wheels and delivered to the second carrier wheel by which it carried under the platens coacting with said second carrier. The portion now hanging down from the second carrier wheel on the opposite side thereof from the cleaning wheel Gr and on the side adj oining the cleaning wheel N is the remaining uncleaned portion of the leaf. This nneleaned part of the leafis guided into the opening between the breast plate or cleaning bed and the second cleaning` wheel. When it has passed across the face of the second cleaning wheel the leaf fiber has been entirely cleaned and scraped from end to end and is delivered to the rear of the machine completely cleaned of all pulpy matter.

YVhile I have shown carrier wheels for moving the leaves across the face of the cleaners and from one wheel to another and believe such construction to be preferable, l do not wish to be limited thereto as other forms of carriers might be used without departing from the scope of my invention. It is obvious also that many minor changes might be made in the proportions and arrangementsI of parts, without departing from the scope of the invention.
