Specification of Letters Patent.

Patented July 24, 1906.

Application filed March 21, 1905. Serial Nor 251i246;

To all whom it may concern.-

Batangas, Philippine Islands, have invented a new and Improved Stripping and. Cleaning Machine, of which the following is afull, clear, and exact description.

The object of the invention is to rovide a new and improved machine especially adapted for treating the leaf-sheaths or band-like material stripped off the abaca and like plants, and arranged to permit a quick and thorough separation of the pulp and freeing the fibers without injury to the latter, the fibers being completely freed or cleaned of the pulp. The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement,-parts' being broken out. Fig.2 is a transverse section of the same on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of the cleaning device, part being broken out. Fig. 4 is a similar view of the clamping-head for the material being treated. Fig. 5 is a sectional side elevation of the same. Fig. 6 is a side elevation of a modified form of the improvement, and Fig. 7 is a perspective view of the endless-chain carrier for the clamping head.

A suitably-constructed frame A supports a table B, over which the leaf-sheath or bandlike material is drawn by the use of a head C, in which is clamped or otherwise secured one end of said band-like material. The material during its movement over the table in the direction of the arrow a is successively acted on by a stripper D for removing the main portion of the pulp and freeing the fibers, then by a series of rolls E for preventing the fibers from curling up, and finally by a cleaning device F for removing any adhering pulp from the fibers.

The head C'(shown in detail in Fi s. 4 and 5) consists, essentially, of a fixed c ampingj aw C and a movable clamping-j aw C hinged at its forward endat C to =the-for= ward end of the fixed clamping-jaw C, the said jaws being of zigzag shape, as'plain-ly' indicated in Fig. 5, to securely clamp the material between the jaws when the latter are closed. The free end of the hinged clamping-j aw C isadapted to be engaged by a spring-catch C, held on the free end of the other jaw C, to hold the aws in aclosed position with the material clamped between the same during the time the head moves over. the table B. The fixed clampingjaw C is fas tenedat its sides by hooks C or other means to carriers G, fastened to longitudinally-extending traveling beams H, arranged adjacent to the sides of the table B, and the under sides of the beams H are mounted to travel between sets of rollers H H carried by the frameA, and the said under sides are also provided with longitudinally-extending racks H in mesh with pinions I, secured on a transversely-extending shaft I, journaled in suitable bearings arranged on the main frame A. On one outer end of the shaft 1 is secured a gear-wheel 1 in mesh with a pinion I fastened on a driving-shaft I journaled in the main frame A and carrying at one end a hand-wheel 1 under the control of the operator for turning the shaft I to rotate the shaft 1 by means of the pinion I and gear-wheel P. The rotar-y motion given to the shaft 1 and its pinion I causes the latter to impart a traveling motion to the racks H and consequently to the beams H and the head C, attached to the carriers G, fastened to the said beams, so that the said head 0 and the material clamped therein are drawn forward over the table B in the direction of the arrow 0/, it being un-. derstood that the portions of the material not clamped in the head C are dragged behind the head over the table.

The stripper D extends transversely across the table B andis in the form of a heavy block of metal having on its bottom a forward extension tapering to a sharp edge, and,

on the sides of the stripper are formed studs D, carrying rollers D adapted to travel over the carriers G when the latter move'forwardly with the beams H to raise the stripper For the purpose mentioned each of the car- 'riers G has its forward end in the form of an incline G, terminating in a horizontal top G leading to an inclined back G down which the rollers D travel to bring the stripper D into contact with the material trailing behind the head C. The stripper D is provided at its middle with an upwardly-extending stem D mounted to slide vertically in a suitable bearing J, carried by a framework J, supported on longitudinally-extending rails J attached to the main frame A. The up per end of the stem D is pressed on by a le- 'ver D fulcrumed at D on the frame J and carryingat its free end an adjustable weight D to hold the stripper D with suflicient force in contact with the material to enter the pulp thereof and to separate the pulp from the fiber during the time the material is drawn along under the stripper D. As shown, the weight D screws on the threaded end of the lever D to allow of conveniently adjusting the weight to bear with more or less force on the stem D of the stripper D.

Each of the rolls E for preventing the fibers from curling up while traveling over the table between the stripper D and the cleaning device F extends transversely of the table B and is journaled in the lower ends of arms E, fulcrumed at E? on brackets J attached to the rails J The upper ends of the arms E are pressed on by springs E at-' tached to the rails J 2 and extending in opposite directions, so as to allow the arms E to swing either forward or backward, the rollers E, similarly to the rolls D being adapted to travel up and down the inclines G and G of the carriers G whenever the head passes under a roller. When the head 0 has passed a roller E while traveling in a forward direction, then the roller E engages the fiber and holds the same firmly down on the table B to prevent the fiber from curling up during its travel from the stripper D to the cleaning de vice F.

The cleaning device F consists, essentially, of two jaws F and F of which the jaw F is carried by the table B and extends into a transverse recess in the same, and the upper surface of the jaw F is rounded off and has a covering F of rubber, the top of the cover being approximately flush with the top of the table B. The other jaw F is rounded at its under surface and provided with a covering F so that when the fibers are drawn between the rubber-covered jaws F and F the pulp is completely stripped off the fibers to free the latter of any pulp, thus thoroughly cleaning the fibers. The uppermost jaw F is provided with an upwardly-extending stem F fitted to slide in a bearing J, carried by a frame J 5 attached to the rails J and the uper end of the said stem F is pressed on by a lbver F, carrying an adjustable weight F similar to the weight D on the lever D On the ends of the uppermost jaw F are journaled rollers F adapted to travel over the inclines G and G of'the carriers G to raise the uppermost jaw F to allow the head 0 to pass underneath the same, it being understood that after the head has passed the jaw F is immediately forced downward onto the fibers to press the same between the coverings F 3 and F of the jaws to free the fibers of pulp during the time the fibers are drawn between the jaws.

The operation is as follows: The head C when detached from the carriers G and when in an open position permits one end of the band-like material to be placed on top of the jaw C with the pulp side up, and when the stalks have been arranged in this manner then the jaw C is swung down into a closed position and locked therein by the springcatch 0 The head C thus carrying the material is now attached to the carriers G by the use of the hooks C or other means, the carriers then being in the right-hand end position of the machine on the beams H. The operator now turns the hand-wheel I so as to impart a forward traveling motion to the beams H, carriers G, and head C, and during this forward traveling motion the head C is passed under the stripper D, which is raised by the carriers G to allow thehead to pass under the stripper, and when the head has passed the stripper the latter immediately descends, sinks into the pulp, and rests lightly on the fiber, so that the knife or sharp edge skives or strips the pulp from the fiber while the fiber or strands are pulled along by the head C. The main portion of the pulp is stripped ofi the fibers by the stripper D as the head moves onward and drags the fibers along over the table B and under the stripper D. As the head 0 advances the carriers G engage the first roller E to swing the lower portions of the arms E forwardly against the tension of the corresponding forward spring E to raise the rollers E sufliciently for the head to pass under the roller, and when the head has passed the forward spring E immediately draws the arms E back to a normal vertical position, so that the first roller E moves down in contact with the fibers to prevent the same from curling up while moving forward over the table B. This operation is repeated for the several rollers E until the head finally passes under the jaw F temporarily raised, as previously described, the jaw after the passage of the head C immediately descending for engaging the fiber to clean the same of adhering pulp, as previously explained. When the fibers have been drawn through the cleaning device F, then the operator stops the hand-wheel I and disconnects the head 0 from the carriers G for the removal of the cleaned fibers from the head. As soon as the head C is removed from the carriers G the operator turns the TIO time

hand-wheel I in the reverse direction, so as to move the beams Hin the inverse direction of the arrow (1 to bring the carriers G back to a starting positionthat is, back to the right-hand side of the machine, the jaw F being lifted during this return movement to allow the-head G to pass, and the arms E, carrying the rollers E, swing in the reverse direction for the same purpose, and the stripper D is raised to permit the head C to returnto its starting position, the several so that the above-described operation canbe repeatedv as soon as another filled head is connected with the carriersG.

In the modified form illustrated in Figs. 6 1

and 7 the beams H are dispensed with and in their stead endless sprocket-chains K are em:

ployed passing over sprocket-pulleys K and K journaled on the frame A a distancebeyond the ends of the table B. The sprocketchains K are provided with sets of projections or hooks K adapted to engage recesses G formedin the under side of the carriers G, employed for supporting a headCin the manner previously described, it being understood that the head 0, with its carriers and the material-clamped in the head, is placed on a table L, arranged at one end of the machine to allow of pushing the head 0 forward sufiiciently far for the hooks or projections K to engage the recesses Gr to carry the carriers G and the head C along. When the head C, with its carriers G, is moved over the table B, the material is acted on successively by the stripper D, the rollers E, and the cleaning device F in the same manner as above described, so that further description of this part of the machine is not deemed necessary.

hen the head C and its carriers reach the left-hand end of the machine, then the forward ends of the carriers pass onto rollers N,

thus disengaging the hooks K from the aper tures G and allowing the head C and its carriers G to slide down the rollers N, arranged in an inclined plane, for the head C and its carriers to finally land on a receiving-table 0. By reference to Fig. 6 it will be seen that two sets of hooks K are employed, arranged in such a manner that when the head C and its carriers G leave the hooks K at the left-hand end of the machine and pass over the rollers N then another head C can engage the other set of hooks K now standing at the righthand end of the machine. In order to impart a continuous traveling -motion to the sprocket-chains K, gearing P may be employed similar to the gearing previously described and used for imparting a forward and backward motion to the beams H. The gearing for the endless sprocket-chains K may be driven by hand or by pulley and belt from other machinery. As shown in Fig. 7, the sprocket-chains K are preferably connected with each other by transverse bars K at the hooks K to cause the sprocket-chains to travel in unison.
