MACHINE FOR GETTING THE PULP OUT OF PLANTS FURNISHING TEXTILE FIBERS.

Application filed July 2,

To all whom it may concern:

Be it known that I, ANDRE HAUsnu, citizen of the Confederation of Switzerland, residing at Mexico, D. F., Mexico, have invented certain new and useful Improvements in Machines for Getting the Pulp Out of Plants Furnishing Textile Fibers, of which the following is a specification.

The present invention relates to a clearing device for fluted rollers.

In certain machines for detaching the fibrous matter from the leaves of plants fluted rollers were employed for withdrawing said fibrous matter from certain crush ing and opening members and to squeeze out the water. I-Ieretofore such fluted rollers were easily getting choked from the pulp collecting between the recesses of the fluting. The present device is intended to provide means for keeping such rollers constantly clean while working so as to be kept ready for work.

The invention is illustrated in the accompanying drawing where similar reference characters denote like parts in several views and where Fig. 1 shows a perspective part view of a roller, Fig. 2 an end View, Fig. 3 a View of a clearing blade and Figs. 4 and 5 end views and cross-sections of certain guide-plates.

The rollers are generally working in pairs, but in the drawing only one roller is shown, this roller B integral with a shaft F is provided at the bottom of the recesses between the flutings with radial furrows I into which blades A are fitted slidably in a radial sense. Guide-plates O having radial slots II registering with said furrows are fixed to the face ends of said rollers by means of screws so as to rotate with the roller and outside of these plates other guide-plates D are sleeved to the shaft and secured fast to the framing of the machine, not shown, by means of two bolts E. An eccentrically arranged groove G cut into the inner face of these latter guide-plates constitutes a race or runway for lugs K provided at the ends 1923. Serial No. 849,178.

of the blades A which are extended over the end faces of the rollers through slots H of plates G into the inner face of guideplates D.

The eccentric races G are disposed in such a way that when roller B is rotated the blades of the side of the roller which is engaged with the fellow-roller will be completely sunk into the furrows but will suc cessively be withdrawn while moving to the other side so as to expel on this outer side any waste matter which could have collected between the flutings of the roller.

I am aware that a hollow roller with a plain surface has already been known hav ing radially arranged blades extended through slots in said rollers surface and kept in position by an eccentric rim rotated with the roller. But the purpose of such construction was to form rollers with partly fluted and partly slotted surfaces. In these rollers, when arranged in pairs, the fluting of one roller would alternately engage the slots of the fellow-roller and the eccentric was made adjustable in order to vary to some extent the depth of fluting according to the required treatment of the fibrous matter fed between said rollers. Rollers of such kind would never work satisfactorily as cleaners, as will those described and shown by the present inventor. Therefore I do not claim such a device, but what I claim as new and want to secure by Letters Patent is.

I claim:

Cleaning device for fluted rollers having members sunk into furrows provided in the recesses of the fiuting and means adapted to move said members in aradial sense, said means consisting in plates arranged rotatably with said roller and having slots registering with said furrows and stationary guide plates having eccentric races for lugs provided at the ends of-said members all substantially as shown and described and for the purpose set forth.

In testimony whereof I aflix my signature.

ANDRE HAUSER.
