TOBACCO STEMMING MACHINE Application filed October 28, 1931. Serial No. 571,598,

The present invention relates to improvements in tobacco stemming machines and especially with the means for removing the tobacco strips from the stemming elements, and applying it in particular to the type of stemming machine which has stemming elements mounted on chains at spaced intervals.

It is an object of the invention to provide an auxiliary surface in cooperation with the stripping elements for the purpose of preventing the tobacco from moving out of the range of the cleaning roll or rolls and there by accomplish or provide for the complete removal of the tobacco from the carding member. It is a further object of the inven-, tion to provide various forms for the auxiliary surface.

The invention is illustrated on the accompanying drawings in which like reference numerals indicate corresponding parts throughout and in which:

Figure 1 is a side view with, a number of parts in section of the stemming mechanism of a stemming machine showing the yielding surface brushes.

Fig. 2 is a similar view of a modified con struction,

Fig. 3 is a view similar to Fig. 1 showing a further modified construction.

Fig. 4: is a view similar to Fig. 1 showing the upper right end of the mechanism of a still further modified construction,

Fig. 5 shows a number of detailed views of a modified supporting surface, and

Fig. 6 shows a number of detailed views of the cleaning rolls. 7 The operation of the stemming machine as illustrated is as follows:

The tobacco leaves are held by their butt ends 34 between the

endless conveyor belts

32 and 33, Figs. 1 to 3. These belts advance the tobacco leaves side ways between the upper and lower pairs of

chains

35 and 36 which are carried on. the

sprocket wheels

37, 38, 39 and respectively. Mounted on these chains are bars 4 at regularly spaced intervals each of which are provided with the carding member 5 or other means forstripping the leaves from the stems. It will be seenthat as the bars 4 come around their

respective sprocket wheels

37 and 39 in the 3 direction of the arrows they will meet in a cooperative manner and the carding on the corresponding bars will move along the stem of the tobacco to remove the leaf therefrom. When these'bars o-r stripping elements reach

sprockets

38 and 40 they separate, a part of the stripped leaf being carried upward by the upper bar and a part is carried downward by the lower bar. A cleaning roll 7, Fig. 1, is provided for brushing the stripped leaf out of the teeth of the carding member 5. A cleaning roll alone, however, does not have the desired effect as the stripped leaf will tend to fall behind or in front of the bars L and thereby will be out of reach of the cleaning roll 7. For this reason and according to the invention yielding surfaces are provided to procure a surface for the tobacco leaf. In Fig. 1 the brushes 1 are mounted on a segment 2 secured to the shaft 3 and which providea yielding surface which is so timed as to follow closely behind the strip per bars 4 which are faced with the carding member 5 to which the tobacco leaves 6 cling after having been stripped from the stems. The brushes 1 form a supporting surface for the leaves 6 and keep the leaves from falling inwardly towards the shaft 3 and away from the cleaning roll 7. The stripped leaves are thus held out in contact with the cleaning roll 7 which is rotating in the direction of the arrow and thereby enables the cleaning roll to pull them out of the teeth of the carding 5.

The cleaning roll 7 is shown in Fig. 1 as being composed of wire carding wrapped around a core but it may be composed of thin sheet metal blades as shown in Figs. 2 and 6 or a corrugated roller 10 as shown in Fig. 3 or even a roller having flaps of leather or similar material 23 as shown in Fig.4. In Fig. 2 the

stripper elements

4 and 5 are both preceded and followed by segmental surfaces 8. These surfaces are integral and secured to theshaft 3. The forward part of segment 8 is provided to prevent the tobacco leaf 6 from falling over the front of the

stripping elements

4 and 5 and which will hold the tobacco in the path of the cleaning roll 31.
