Application filed January 21, 1908. Serial No. 411,895.

To all whom it may concern:

Be it known that T, Anrnun LinNcnLo'r Jaiuns Tarr, a subject of the King of Great Britain, residing in the city of Duncdin, in the British Dominion of New Zea land, inventor, have invented certain new and useful ln'iprovements in Fiber-Dressing tions or steps, in the process of treating and Machinery, of which the following is a specification.

This invention relates to new and useful improvements in fiber dressing machines and it relates more particularly to a machine capable of treating hard fibers such as Manila stalks, hemp or sisal and soft fibers such as Lin/mt 'ussitutssimmm or straw in either a green or a subsequently dry condition.

The invention aims asa primary object to provide novel means for effecting an end to end dressing of the fibers during their continuous travel througl'i the machine and to provide for a novel dressing operation in which the dressing devices travel at a greater speed than the fiber feeding or carrying devices.

The invention aims as a further object to provide novel details of structure and arrangement, residing more particularly in the essential elements comprising cooperating carrying cylinders and a chain provided with various fiber dressing devices and movable with relation to portions of the peripheries of said cylinders.

In the drawings forming a part of this specification, Figure 1 is a longitudinal sectional view of a machine constructed in accordance with the present invention. Fig. 2 is a top plan view of such machine.

Similar characters of reference denote corresponding parts throughout the said views.

The various operating elements of the present machine are supported directly or indirectly from a frame 1, which at its forward end is provided with bearings for the upper and lower transverse parallel shafts 2 and 3 that carry the respective fiber carrying cylinders d and 5 which cylinders rotate in relatively opposite directions. Such opposite rotation is effected by means of intermeshing pinions 6 and 7 provided on the shafts 2 and 3, the latter shaft carrying also a band wheel 8 which may be connected with any source of driving power.

Above the cylinder t a number of cooperating pairs of fiber feeding and breaking rollers 9 are mounted in any suitable manner, the fiber being introduced between the l l l cooperating rollers 9 from an inclined shelf 10. 'idditional feeding rollers 11 are mounted above the cylinder 4: in suitable spring pressed bearings 12 of approved form by means of which the rollers 11 are held in contact with the peripheral surface of said cylinder 4t. If desired, for certain operadressing fiber the foremost roller 11 may be circumferentially corrugated as shown in Fig. 2. i

For the purpose of removing any fibers which might otherwise cling to the surface of the rollers, OSPOClilllY when the fiber is treated in a wet condition scraping blades 13 are provided for each of the cylinders l: and and the rollers 11, which blades lie against the periphery of said rollers as is obvious. T he rollers 11 are positively driven. Toward this end their shafts lat are provided with pinions 15 which are smaller than and in mesh with the pinion 6.

In the rear of the cylinders 4: and 5 and the mechanism appurtenant thereto, upper and lower transverse shafts 16 and 17 are supported, between which are arranged intermediate shafts 18 and 19. The shaft 18 is carried by stationary brackets 20 and the shaft 19 is carried by brackets 21 which are adjustable longitudinally of the corresponding brackets 20 by conventional bolt and set nut connections as 20 the bolts passing through registering slots 22 in said brackets The shafts 16 and 17 carry at their ends chain or belt supporting pulleys and the shafts 18 and 19 carry guide pulleys 2d and 25, the pulleys 25 being more in the nature of tension pulleys, and being of course positioned with relation to the pulleys 241 in accordance with the adjustments of the brackets 21. The shaft 16 also carries a band wheel 26 which may be operatively connected to the band wheel 8, the latter being stepped as shown in Fig. 2.

Parallel belts or chains 27 are passed over the pulleys 23, 24- and 25, said belts or chains, being of course driven by the upper pulleys 28.

The belts or chains 27 conjointly support transverse scrapers 28, which may be combined for the different processes of treat ment with small, rollers 29, combs 30, or narrow brushes 31, all of these elements, 29, 30, and 31 being shown incidentally in Fig. 1.

For the purpose of wetting the fibers, if desired, during the dressing and cleaning operation water may be sprayed thereon through a pipe 32 which extends transversely of the machine in the rear of the rollers 11.

For the purposes of treating dry fiber, a guide tucker 3% is employed, such guide tucker being arranged transversely in the throat of the passageway between the cylinders 4t and and being capable of a slight movement or play with relation to said cylinders, as by crank mechanism (not shown). As an adjunct of said guide tucker and located rearwardly thereof I preferably employ an air blower 34. It is obvious that the guide tucker 33 and air blower 8% are not necessary in treating wet fibers, as these will cling to the surface of the cylinder t.

In ope *ation, the fiber is fed through the breaking rollers 9 and the rollers 11 and cylinder rand passing over the periphery of the latter is treated by the devices ca "ried by chains 27 which devices, traveling in the direction of rotation of the cylinder at but at a greater speed than the said cylinders dress the fiber, scraping, rolling, combing or brushing off waste parts as needed. During the continued rotation of the cylinders and 5, the fibers enter therebetween and are discharged therefrom. Arrows indicate the relative directions of motions. quicker movement of the fiber dressing at tachmcnts throws the back ends of the fiber against the baflier plate and so the said back ends of fiber are driven between the dressing attachments and cylinder 5, the fiber still passing through between both cylinders. Thus it is dressed from end to end, which operation, has hitherto been dilficult of attainment unless by complicated arrangements.

The frame 1 may be provided with a suitable drain (not shown) through which the water introduced from the pipe 32 is led otl.

Having thus fully described my invention, I claim 1. In an apparatus of the type set forth, in combination, two oppositely rotatable The 2 cylinders arranged to co-act in delivering fibers therebetween, one of said cylind rs receiving and carrying material fed to its peripheral surface, the said material being ultimately carried between the cylinders, and fiber dressing means cooperating with the peripheral surfaces of the cylinders and movable continuously in one direction with relation to the peripheral surfaces of both cylinders. V

2. In an apparatus of the type set forth, in combination, a rotatable cylinder, means for feeding fibers to the peripheral surface of said cylinder, chains movable concen trically of a portion of said peripheral surface, said chains having movement at a speed greater than the speed of travel of said cylinder, and fiber dressing devices carried by said chains.

3. In an apparatus of the type set forth, in combination, two oppositely rotatable cylinders, means for feeding fibers to the peripheral surface of one of said cylinders, and fiber dressing means comprising chains movable concentrically of adjacent portions of the periphenl surfaces of said cylinders at a speed of travel greater than the speed of travel of said peripheral surfaces and fiber dressing devices carried by said chains.

a. In an apparatus of the type set forth, in combination, two oppositely rotatable cylinders, one of said cylinders receiving and carrying material fed to its peripheral surface, fiber dressing means cooperating with the perhoheral surfaces of said cylinders and moving continuously in one direction with relation to the peripheral surfaces of both cylinders, and a guide tucker disposed in the throat of the passageway between said cylinders.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.
