On the other end. of the shaft 9, an actuating arm II is securely ‘mounted, which carries. a roller I2 on apin pro ,‘ hemp material as indicated by A is placed on with its fore end reaching the supporting plate I8 ‘ the. roller 8. When the. lever 2 is moved to a position shown by the dash and dot line B in Fig. 1 by_a driving mechanism (not shown), the roller I 2 is moved to its up position shown in Fig. 3 and bydotted line in Fig.>1 to be in contact with the under-side of the endless band ‘I through means of the link 3,'arms II] and ‘I I. Then, hemp ma .terial is pressed against the endless band ‘I by the rollers I2 and 8, hemp material being carried v forwards by co-action of the endless band ‘I and the roller' I2. When the lever 2 is moved to a __ position indicated by the dash and dot line B in “Big. 3, as mentioned. above, the bar I’! is moved 1 upwards through means of a pivoted lever 4, _ whereby the ldrivingspawl I5 is brought into dis vided on one end, for feeding hemp material. engagement with the toothed wheel I6, so that Actuating arms I3 and I3’ aresecurelymounted 40 ' 45 50 the supporting plate I8 carrying the hemp ma on, a shaft I4 supported on the frame. A driving terialis maintained in its horizontal position. As pawl I5 is operatively mounted on and between hemp materialis carried forwards, the lever 2 is the actuating arms I3 .and I3’ by means of a moved to a. position indicated by the dash and pivot I5’, and is in engagement with a toothed dot line B’, whereby the roller I2 is moved to its wheel I6 securely mounted on the shaft I4. One down position as shown in Fig.1 through means end of an extension of the pawl is pivotally con of the link 3, arms I 0 and II. The rear end of nected with one end of a connecting link I 1 which hemp material on the roller I2 will be brought is connected with one end of the lever 4. I8 rep downwards with said roller, the rear end of the resents a supporting plate for hemp material, a hemp material which rested on said supporting number of which are connected by means of arms plate having been removed, as the bar I‘! is moved 45 I9 at suitable intervals to a revolving shaft I8’ downwards through means of the levers 2 and 4, supported on the frame. On the shaft‘ I8’, a and the toothed wheel I 6 is thereby driven by the toothed wheel 29 is securely mounted, which is pawl I5 to rotate the shaft I8’ and hence the in engagement with the toothed wheel I 6. Beat material supporting plate I8 through means of ers 22 and 23 are rotatably mounted on a ma the toothed wheel 20 meshing with said toothed 50 chine frame 2|, and adjustable pressing mem wheel I6, and a following next one of the material bers 24 and 25 are provided to co-operate with supporting plates is brought to a horizontal posi the beaters 22 and 23 respectively. 26 and 21 tion, on which new hemp material is to be placed, represent blades, 26' and 21' their dies, and 28 and then the roller I2 will be moved upwards an endless band arranged over rollers 29, 30 and again. In this manner, hemp material is carried 55 2,108,568 2 forwards by means of the rollers l2 and 8 and the endless band 1, and in the meantime the pressing member 26 will be moved to its up position and the die 23’ will be moved to its down position by suit Cl able means (not shown) and said pressing mem her and the die will be at rest in these positions for an interval of time. tween the rollers 35 and 29 by hanging thereon in a doubled or folded position. The treated ma terial hung on said cross bars will be moved with the chains 40 and carried through and be When the fore end of the material reaches a position somewhat for ward from the die 26’, the roller 12 will be moved downwards from the feed belt and the pressing member 24 will be moved downwards toward the beater 22, while the die 26' is moving toward the blade, with hemp material resting on it. After an interval of time, the pressing member 24, the ' beater 22, the blade 26 and the die 26’ are brought in their respective operative positions, and the rear part of hemp material will be opened by the tween the endless bands 31 and 28, and as soon as the cross bars are moved off the said endless bands, the treated material will hang down and be received on the pole 48. Thereupon com pleting the hemp dressing. In a short time after the commencement of the reverse movement of 10 material, on the right side the pressing member 24' will be moved upwards and the die 26’ will be moved downwards, and accordingly no work will be effected on the right-hand equipment. Thus, the regular operation of the machine is repeated 15 by means of cams, levers and toothed wheels which are arranged in timed relation in a suitable beater 22. When the fore end of the hemp ma— terial reaches a position near the fore blade 21 and the die 2'l' on passing through between the manner. endless bands 28 and 33, the endless band 38 and the die 21’ are moving downwards and the press when a material is supplied in position on a sup ing member 25 is moving upwards, so as not to interfere with the forward movement of mate rial. In due time, said endless band, die and pressing member will stop, and the fore end of material will advance to a point somewhat for ward of the center of the beater 23. At that time, the endless band 38 and the die 21' will be moved upwards and the pressing member 25 will be moved downwards, and when said band 38 is brought in contact with the endless band 31, ma terial will be moved in a reverse direction as will be evident from the fact that belts 28 and 31 being in contact with each other will cause the lower portions of the belts in contact with the material to move in reverse directions with re spect to each other. In the meantime, the fore end of material will continue its forward move ment, and the length of material between the 40 portion treated with the beater 22 and blade 26 and the untreated portion will reach a position somewhat forward of the center of the beater 23, and the pressing member 25, the blade 21 and die 21’ will not be brought in their working positions, although material is moved in the reverse direc tion, but after an interval of time they will be brought in their working positions, and after said length of material reaches a position somewhat forward of the blade 21 and the die 21' the un treated portion of material will be treated with the fore beater 23 and blade 21. Thus, the treated material is now carried in the reverse direction on passing over the roller 39 of the end less band 38 and by this time the cross bars 44 provided between the chains 40 will come in a position for receiving the treated material be From the foregoing, it will be seen that the machine according to the invention is arranged 20 to entirely open and dress fibre while in operation porting plate, and accordingly the operation of dressing the material can be done economically and continuously requiring only attendants for 25 supplying material on the supporting plate and for dealing with the dressed material delivered, without need of skill. Having now particularly described and ascer tained the nature of my said invention and in 30 what manner the same is to be performed, I claim: A hemp dressing machine comprising a mate rial support, an endless feed band mounted near said support, a guide roller mounted on an inter 35 mittently oscillatable arm for feeding said mate rial and adapted to be moved into and out of en gagement with said endless feed band, two spaced beaters, movable pressing members to co-operate with said beaters, cutting blades and movable 40 dies co-operating therewith for scutching the material passing the beaters, endless intermediate conveying bands arranged one above the other in intermediate spaced relation between said two beaters, endless chains arranged to travel be 45 tween said intermediary endless bands and in contact therewith and provided with a number of cross bars for carrying material from the ma chine, and co-operating endless bands arranged to- contact said upper and lower intermediate 50 endless bands respectively, one of said last named endless bands being movable in and out of contact with a corresponding intermediary endless band to intermittently feed the material 65 to the chain conveyer.
