To all whom t may conce/rn:

Be it known that I, Lno W. LAWRENCE, a citizen of the United States, residing at Winston Salem, county of Forsyth, and State of North Carolina, vhave invented a new and useful Improvement in Tobacco- Stemming Machines, of which the following is a specification.

This invention relates to an improvement in tobacco stemming machines.

One of the objects of the invention is the production of a simplified machine capable of greater production thanhas heretofore been found obtainable, and with decreased initial and maintenance cost. Another object of the invention is the production of a machine in which bunches or hands of tobacco leaves may be introduced withinits range of action, automatically arranged, and then successively operated upon to effect the stripping of the stems. Another object is the production of a machine in which the leaves are automatically fed or advanced in bunches, automatically arranged as they are advanced, and then successively and progresslvely operated upon to strip the stems. Another object is the production of a manipulating mechanism for effecting the arran ment of the stem butts substantially in a line to prepare them for engagement with stripping means. Another ob]ect is the production of feeding means for advancing the leaves to stripping position, and stripping means coperative with the feeding means within the range of action of the latter, in order to eliminate the necessity heretofore existing for transferring leaves from feedy lng means to stripping means, thus avoidn the diiculties attendant upon re-handhng. Another object is the production of a stripping medium traveling with the feeding means at stripping position, and stem drawing means coperative with the stripping means to effect the stripping of the stems as the leaves are fed forward. Another object is the production of a machine in which all of its component parts are continuously operative so that no time is lost or diliculty encountered due to intermittent operation of one or more of the several mechanisms. Another object is the production of self clearing stripping devices. With these and other obJects not specifically men- Afurther provided stem tioned in view, the invention consists in certain parts, constructions and combinations which will be hereinafter full described and then specifically set forth 1n the claims hereunto appended.

In the accompanying drawings which form a part of this specification and in which like characters of reference indicate the same or like parts, Figure 1 is a side elevation of a machine constructed in accordance with the invention; Fig. 2 is a plan view of the structure shown in Fig. 1; Fig. 3 is a detail sectional view of the manipulating devices, the stripping devices, and the stem drawing means; Fig. 4 is a cross-sectional view taken mainly on the line 4 4 in Fig. 3, but in part stepped back from said line; and Fig. 5 is a detail sectional view of the manipulatin devices.

In carrying the invention into effect, there are provided means for feeding a bunch of leaves, and means arranged and adapted to engage and act upon the leaves successively to strip their stems. There is further provided stem butt arranging means adapted to gather and aline stem butts that are moved in irregular formation into its range of action by the feedin means. There is rawing means arranged and ada ted to successively engage stem butts acte upon and delivered to it by the arranging means. There is further provided stripping means cooperative with the stem drawing means and operative within the range of action of the feeding means.

In the best constructions, the leaf feeding means, the stem butt arranging means, the stem drawing means, and the stripping means all operate continuously and within the range of action of the feeding means, so that the tobacco leaves are slpported by .the feeding means to the end o the stripping operation, thus eliminating the necessity for mechanism for transferring leaves from .the stem butt arranging means to the stripping means, and thus completely avoiding the dropped leaves or drops which resulted from imperfect action of such transferring yieldingly mounted and the other floating, whereby a manipulating action upon the stem butts is pro uced to arrange them substantially in a single line for successive de livery to the stem drawing means. In the best constructions also, the stem drawing means consists in a pair of stem drawing rollers the axes of which are arallel to the lineV of movement of the fee ing means and which rotate at high speed in order that the stem may be drawn from the leaf during a relatively small and slow movement of the feeding means. In the best constructions also, the stripping medium consists in stripping members that are prolected into engagement with the leaves advanced by the feeding means at stripping position, and then retracted to clear them from strip. In the best' constructions also, the stripping means travels with the feeding means an at substantially the same speed, at stripping position. All of the above mentioned means, mechanism and devices may be varied in construction within wide limits.

The machine selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the precise details of the structure shown and described. Moreover, certain parts of the invention are capable of use independent of other parts, and such independent use is contemplated.

Referring to the drawings, which, as before stated, illustrate but one ofmany ossible concrete embodiments of the invention, 6 indicates the main frame of the machine, and this frame is mounted upon the supporting legs 7. Extending laterally from the main rame 6 are two side brackets 8 and 9, one on either side of the machine. Similarly mounted, but above the brackets 8 and 9, are two shorter side brackets 10 and 11. Mounted in suitable bearings in the side brackets 8 and 9 is a shaft 12 extending across the machine. Similarly mounted in the side brackets 10 and 11 is a shaft 13, also extending across the machine. Fast upon the shaft 12 is a drum or pulley 14, and over this drum runs a belt 15. The belt 15 also runs over a small idle pulley 16 fixed upon a shaft 17 which is journaled in suitable journal boxes 18, one in the side bracket 8 and the other in the side bracket 9. Both of these journal boxes are adjusted for belt tightening purposes by means of adjusting screws 19. Similarly, fast upon the shaft 13 is a drum 20 over which runs a belt 21. The belt 21 also runs over an idle pulley 22 fast upon a shaft 23 which is 'ournaled in boxes 24, these boxes being a justably secured to the side brackets 10 and 11 by means of bolts 25, only one of which is shown. These two belts 15 and 21 constitute the tobacco leaf feeding means of the machine, and they operate continuously. The means for so operating them includes two intermeshing gears 26 and 27, respectivel fast upon the shafts 12 and 13. The gear 2% is in mesh with an intermediate pinion 28, and this intermediate pinion is in mesh with a driving pinion 29 fast upon a shaft -30 extendin across the machine and mounted in suita le bearings in the main frame 6 before referred to. Upon the opposite end of the shaft 30 is fixed a worm wheel 31 which meshes with a worm 32 fast upon a shaft 33. The shaft 33 is the main power shaft of the machine and carries a fast pulley 34 and a loose pulley 35. The shaft 33 is driven by means o a belt not shown.

For the purpose of assisting the machine operator in placin bunches of tobacco leaves u on the feed be t 15, there is provided a w ip rail and stem abutment which consists in a late 36 secured to two projections from the s1de bracket 8 by means of screws 37. In4

placing a hand of tobacco leaves upon the elt, the operator first unties the hand, then Whips the stem butts on the edge of the plate 36 to loosen the bunch of stem butts, and then lays the bunch of leaves u on the belt with the ends of the stems touc ing the plate 36. I-t will be noted that the plate 36 is spaced a considerable distance from the edge of the feed belt. This is for the urpose of properly positioning the stem utts to be acted upon by mechanism subsequently coming into actlon.

As indicated by the diagrammatic illustration of the tobacco leaves in Fig. 2, the stem butts are fed forward in irregular formation, super osed and unevenly spaced, or, in other wor s, as they naturally lie after the hand is untied and the stem butts are loosened up. It is highly desirable that the stem butts be arranged substantially in a single line before the stripping operation is begun. There is therefore provided stem butt arranging means which consists in a pair of co-'acting manipulating disks 38 and 39 respectively having curved peripheral operating surfaces 40 and 41. The disk 38 is fast upon a shaft 42, and the disk 39 is fast upon a shaft 43. The shaft 43 rotates in a bearing 44 bolted to the side bracket 8 before referred to, but is not driven. The disk 39 therefore floats and is rotated only when stem butts lie between yit and the disk 38. The shaft 42 is splined to the long hub 45 of a bevel gear 46, the hub being journaled in a suitable bearing 47, which bearing is bolted to the side bracket 10 before referred to. In mesh with the bevel gear 46 is a bevel pinion 48 fast upon a short shaft 49 which also carries a sprocket 50. The sprocket 50 is drivenby means of a chain 51 which also runs over a s rocket 52 fast upon the shaft 30 before re erred to. The upper disk is thus driven continuously. For the purpose of permitting stem butts to pass between the superposed disks and to cause them to be manipulated into a single line in so passing, t e upper disk 38 is ieldingly mounted. With this end in view, t e upper end of the shaft 42 is provided with an enlarged head 53 against which one end of a spring 54 bears. The other end of the sprin is adjustably positioned by means of an adjusting screw 55 mount/ed in a spring inclosing housing 56 threaded upon the hub of the bevel gear 46. By inspection of the disks in Figs. 1, 3 and 5, it will be readily seen that they are mounted in relative angular relation and that they co-act to form what may be termed a stem gathering throat into which the'feed belt moves the stem butts in irregular formation as they are placed upon said belt b the machine operator. Since only one o the disks is driven, the Stem butts will not be positively seized by the disks and carried along thereby as presented to them. The upper disk will yleld and rise as the stem butts pass into the throat and if two or more stem butts are super osed the spring 54 will tend to press them own into a single line. This tendency is aided by the lower disk which will not turnat the same speed as the upper disk but will be more or less retarded v in accordance with the particular formation of the bunch of stem butts. It may even in some instances be rotated backward slightly as the upper disk presses downwardly u on the bunch of stem butts. The action is rther aided by the differential speeds of the `It will be understood that this stem butt manipulating and arranging means delivers the stem butts successively at a definite position;

For the purpose of avoiding the delays and difficulties heretofore encountered in transferring leaves from a feeding means to a stripping mechanism, the machine illustrated is so organized that the stem butt manipulating and arranging means delivers the stem butts successively at stripping position and directly to stem drawing means operating in conjunction with stripping mechanism, and within the range of action of the feeding means. The stem drawin means includes a stem drawing roller 5 formed on one end of the power shaft 33, and a co-acting stem drawing roller 58 formed on a shaft 59. This shaft 59 is mounted in a pair of journal boxes 60 one of which is clearly shown in Fig. 1. These journal boxes are yieldingly mounted and held to their work by means of a pair of springs 61 and adjusting screws 62. The shaft 59 carries a gear 63 which is in mesh with a driving gear 64 fast upon the power shaft 33. The stem drawing rollers may separate enough for operation upon a sin le line of stem butts, without disengaging t e gears 63 and 64. By an inspection of Fig. 1, it will be noted that the main operating surfaces of the stem drawing rollers are spirally knurled` that their entrance ends are in part threaded and in part conical, the conical ends respectively overlying and underlying the manipulating disks 38 and 39. The purpose of the conical ends of the stem drawing rollers is to guide stem butts delivered to them by the arranging means into the range of action of the threaded part of the rollers. The purpose of the threaded part of the rollers is first to guide the stem butts into the range of action of the knurled part of the rollers, and second to begin the drawing action `without `danger of breaking the stems. The rollers rotate at high speed and the gripping power of the threaded part thereof is inferior to that of the knurled part. While feeding the stem butts toward the knurled part of the rollers, the threaded part exerts force enough to start the drawing action, with more or less slip however, so that the stems will not be broken. By the time the stem butt reaches the knurled part of the rollers, slippage ceases and the drawing action is completed by the continued operation of the rollers. The spiral nurling of the rollers produces a feeding effect upon the stems along the rollers as said stems are drawn therebetween. When the stem butts are fed along ,close together, the stem drawing rollers act upon them successively and progressively; that is to say, the drawing action upon one stem is begun before the drawing action upon the preceding stem is completed.

For the purpose ofeii'ecting the stripping of the stems as they are fed along by the feeding means and arranged by the manipulating means, and without causing interruption of the travel of the leaves through the machine, continuously operative mechanism presenting a substantially continuous stripping medium traveling with and at substantially the same speed as the feeding means at stripping position, is provided. This mechanism consists in a pair of stripping devices, superposed and substantially alike in structure and action. These devices each include a plurality of stripping members capable of being projected into engagement with the leaves advanced by the feeding means, and retracted out of engagement therewith. Since these devices are alike, a description of one will answer for both. The head of the drum 14 nearest the stem drawing rollers 57 and 58 is marked stripping members is provided with a recess in constant engagement with an orbital stationary cam 68. This cam is adjustably secured to the side bracket 10 by means of bolts 69. By an inspection of Fig. 4, it will be understood that as the drum 20 and support 66 rotate, the stripping members 67 will be projected beyond the support and into engagement with the leaves carried by the feeding means, just before the stem drawing means comes into action. It will be further understood that just after the stem drawing action is completed, the stripping members will again be housed within the support, and that this housing action will disengage the stripping members from the strip and leave the latter free to fall clear of the oncoming leaves. The support 65 of the drum 14 is similarly provided with a plurality of stripping members 70 the movement of which is controlled by a cam 71 similar in all respects to the cam 68. It will be further understood that the speed of the stem drawing rollers is high and that the speed of the feed belt is relatively low, and that in consequence the stem stripping operation is completed while the stripping members are interlocked, as shown in Fig. 4, so that the leaves cannot escape the action of said members. It is to be further understood that the strip will fall below the drum 14 into a chute or other receptacle not shown. i

In view of the foregoing, a detailed description of the operation of the machine is deemed unnecessary and is therefore omitted in the interest of brevity.
