Definitions
- One object of the invention is to do awa with all these auxiliary devices.
- a -inrther object is to secure improved means to prevent the twistingof the fibres round the drum shafts during the scutching operation and a still further object is to provide special means whereby the dust resultingfr'om the operation is removed automaticallyf 7
- the invention essentially consists in the special arrangement and combinations of parts as herein after fully described and pointed out in the I appended claims.
- Fig. 1 is a diagrammatic elevation and vertical section of a complete machine, composed .of two pairs of scutching drums, which each treat successively rather more 40 than half the length of the straw, this straw being reversedby any suitable device after havingbeen treated in the first mechanism.
- Fig. 2 gives a cross section, showing especial-ly the cooperation of a band conveyor 7 with a curved guide against whichit is kept pressed by'its tension. V.
- FIG. 1 indicates the drums proper of which there are two, Whose blades or scutching members: 2 fit one between the other when the drums revolve and strike successively the straw suspended between the two drums 1.
- the blades 2 have a curved form, as shown especially in-Fig. 1, so that the diameter of the drumsinereases from the inlet 3 towards the outlet 4 of the machine.
- Each drum is closed at its ends by discs 5 of large diameter mounted on the driving shaft 6. .VVith each pair of drums there cooperates a curved guide 7 formed for instance of a'rail and carried by curved plate 8.
- an endless belt 9 is kept pressed and passes over the pulleys 10 and, 11, of which the pulleys 10 for instance act as driving pulleys and are supported by tension de vices 12, so as to be able to regulate the tension of the belts 9 and to press. the latter automatically against the guide-rails 7.
- Each pair of drums is enclosed in a protecting casing 13, fitted on top with an exhaust chimney 14.
- V i i t will be observed that in a machine constructed as above described the straw to be scutched is conveyed only by aid of the belt conveyor, rope or other similar member 9 cooperating with the guide track or rail 7 bent in the form of a circular are, so that the necessary pressure, to maintain the straw to be scutched, between the belt conveyor andthe" guide track, is obtained automatically by the pressure exerted by the belt, rope or other member on the guide track as a consequence of the tension which tends to straighten it.v
- the blades or knives acting on the straw must be provided with a i curved Working surface so that the diameter of the drums increases gradually from the inlet opening for the straw to be scutched till the exit opening.
- the guide track 7 canbe placed so as to allow of the action of the blades nearer to the point where the iibre is held, which allows shorter iibres to be scutched than heretofore and an energetic action to be obtained in the central portion.
- pairs of drums revolving towards each other, scutching members mounted on the said drums, a flexible member formed by a belt or rope extending longitudinally above the drums and a curved guide track, arranged below the said flexible member and cooperating with the same, whereby the necessary pressure to maintain the material to be scutched between the flexible member and the guide track is produced automatically by the pres n fln' bln -l U Q il'o l0 sure or e Mn is memaei on no can ait c track.
- the said blades being curved longitudinally, whereby the drums have a diameter increasing from one end to the other, a guide track arranged longitudinally above and between the said drums, the said guide traciz being bent in the shape of a circular arc corresponding to the curved shape of the scutching blades, means for carrying the said guide track and a conveying belt, the said belt cooperating with the curved guide-track whereby it is pressed on the said guide track with a given pressure to maintain the material to be scutched between the said belt and the said guide-traclc l. in a scutchin g machine, pairs of drums,
- the said blades being curved longitudinally, whereby the drums have a diameter increasing from one end to the other, a guide track arranged long tudii c. ly above and between the said drums,-the said guide track being bent in the shape of a circular arc corresponding to the curved shape oi the scutching blades, means for carrying the said guide track, a belt acting as a conveyor and cooperating with the said guide track, pulleys on which the said belt is guided, the said pulleys being inclined relatively to the vertical plane and means for tensioning the said belt on the said guide track.
