APPARATUS FOR SCUTCHING AND CLEANSING FIBROUS STEMS, LEAVES, AND THE LIKE.

SPECIFICATION forming part of Letters Patent No. 336,395, dated February 16, 1886. Application filed September 21,1885. Serial No. 177,723. (No modeLl Patented in England July 13, 1985, No. 8,161. i

To .Z whom it may concern.-

Be it known that I, WILLIAM EPIIImIM DEATH, a citizen of England, residing at Brixton, in the county of Surrey, England, have invented a new and useful Improvement in Apparatus for Scutching and Cleansing Fibrous Stems, Leaves, and the Like, (for which I have made application for patent in Great Britain, No. 8,464, July 13, 1885,) of which the following is a specification.

For the purpose of scutehing fibrous stems, leaves, and the like, so as to clear the tibers from the pulpy, gummy, and ligneous portions, it has been usual to expose the material to the action of a scutching-wheel having blades or beaters which successively strike the stems, while in some cases jets of water are made to play upon them. The action of the blades or beaters being, however, limited to the small portion of the material which for the time is held up against them by the edge of the table on which it is fed, the operation is tedious and imperfect. According to my invention I remedy this defect by placing within a short distance of the seutching blades or beaters and concentric with the circle in which they revolve a curved shield or guard, along which a current of Water is made to flow, so that the fibrous stems which extend along this shield, being buoyed up by the Watercurrent, are kept within range ot' the scutcliing blades or beaters and are eftectually and rapidly operated on by them, while the matter that is disengaged from the bers is washed away.

Figure 1 ofthe accompanying drawings is a longitudinal section, and Fig. Zisan end view, of a scutching apparatus with myimprovement applied thereto. A

On a suitable framing, A, is mounted a rapidlyrevolving drum, B, having fixed 011 its periphery anumber of beaters, C. Under this drum I iX the curved guard or shield D,

along which liows a stream of water from a tank, E, which is kept supplied so as to overtlow. The stems or materials F to be operated on are held by hand upon a table, G, so as to bend over its edge and extend down along the shield D in the Water-stream, which buoys them up, keeping them within range of the beaters O. Then the parts of the material F that extend along the shield are sut'iiciently acted on the material is withdrawn and turned end for end, so as to expose the rest of it to the action ofthe beaters. The seutehing-drum is cased by a bent cover, H. The table G is k adjustable by screws, so that it can be set more or less closely up toward the beaters C, and it has over it a bent guard-bar, K, to act as a fence for the hands ofthe operator. The tank E and shield Dare held by bolts passing through slotted holes, so that they can be fixed more or less closely up toward the circle of the beaters C. The matter cleared from the bers is washedl down the incline L by the stream that liows along it.

Having thus described the nature of my invention and the best means I know for carrying the same into practical effect, I claim- The combination, with the revolving drum B, having attached beaters C, the feed-table G, and the curved shield D, of the water-tank E, supported at the upper edge of the shield and having communication therewitl1,for causing a current of water to dow down the shield and buoy up the fibers thereon, substantially as described.

In testimony whereofI have signed my name to this specification, in the presence oftwo subscribiug witnesses, this 11th day ofSeptember,

WILLIAM EPHRAIM DEATH. XVitnesses:
