TOBACCO-STEMMING MACHINE.

SPECIFIGATION forming part of Letters Patent No. 589,68 5, dated September 7, 1897.

Application filed November 7, 1896. Serial No. 611,312. (No model.)

To 11.1 111710722 ('15 7716117] concern:

Be it known that I, MILTON O. BAUGHAN, of Richmond, in the county of llenrico and State of Virginia, have invented a' new and useful Improvement in Tobacco-Stemming Machines, of which the following is a specification.

lli'y invention is a machine for removing stems from tobacco-leaves; and it consists in certain novelconstructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention I have had in view the provision of mechanism especially designed to handle tobacco from the point or tip end of the leaf, thus following the plan adopted in stemming tobacco by hand. I thereby follow natures law rather than oppose it, asis the case where the stems are stemmed from the butt-end of the leaf toward the point.

By my improved machine I provide devices for effectually removing the stem, whether such stem be intact and unbroken from end to end or brolten or cracked in one or more places.

In the drawings, Figure l is a top plan view,and Fig. 2 is a side view,of my machine. Fig. 3 is a side view of the stemming device. Fig. i is a plan view of the same. Fig. 5 is a detail section on about line 5 5 of Fig. 3. Fig. 6 is a section on about line 6 6 of Fig. 3. Fig. 7 is a view of the feed end of the stemming device. Fig. 8 is a section on about line 8 8, Fig. Fig. 9 is a detail plan view of the folding mechanism. Fig. 10 is a side view, part in section, of the folding mechanism. Fig. 11 is a section on about line ll 11 Fig. 12 is a section on about line 12 12 of Fig. 10. Fig. 13 is asection on about line 13 13 of Fig. 9, and Figs. 1a and 15 are detail views showing means for preventing the stem from being carried down between the belts.

In the construction shown the invention is carried out by arranging the stemming devices in pairs, providing two main or upright frames A A; but manifestly the invention may be carried out in single sets of devices, or they maybe duplicated to a further extent if it be desired to increase the capacity. The two frame or pair arrangement is, however, preferred, because thereby I arrange the stemming, iufeeding, and leaf-discharging devices so they are unobstructed at their outer sides, as will more fully-appearhereinafter, and I connect the frames A A by a crossyoke B, fixed to said frames and having at its ends depending lugs or portions I3, having box-guides Z), corresponding with the box- 62 guides 12 in the frames A. This yokeB is arranged over the lower stem-feeding pulley D, while a yoke O, having guide-lugs 0, connects the frames A, near the front ends of the said frames. I

As thefolding, stemming, feeding, and discharging dcvices are alike on both sides of the machine the description of one set will answer for both or all.

The machine includes a lower stem-feeding 7o pulley D, a rear guide-pulley E, infeeding belts F and G, a stein-discharger consisting of a stem-guide II and a belt I, a cutter J, and a spring K for keeping the stem in position against guide-plates L and M, together with the folding devices presently described.

The upper and lower belts F and G pass at their rear ends around respectively the lower stem-feeding pulleyD and the pulleyE and attheir front ends around the pulleys F and G. Between the pulleys F and G the belts F and G move in close relation to each other and practically in contact until they reach a' point in rear of the crown of the lower stemfeeding pulley D, when the belt F passes off to the pulley E. This pulley E is mounted in bearings which may be a djustcd by a screw E, and is arranged with its lower surface below the crown of the lower stem-feeding pul- Icy I). The upper pulley F is mounted in adjustable and spring-pressed boxes, so it can yield when necessary, and supporting-pulleys g and a tighteningimlley g may be arranged within the belt G, as shown.

The lower stem-feeding pulley D is jour- 5 naled to the frame A and projects laterally therefrom, as shown. This pulley has a bandface D at its outer end, a circumferential groove D at the inner edge of said band-face, and a feeding face or portion D between the 10 said groove and the frame A. This feedingface is preferably milled, as shown, or otherwise suitably roughened to give it a hold upon the stem of the leaf and aid in pulling and in feeding such stem to the stem-guide in the operation of the device.

Above the main lower stem-feeding pulley D and in line with the feeding-face D thereof I provide an upper stem-feeding wheel I, journaled in yielding bearings and receiving the stem-discharging belt I, which leads at its lower run upwardly and rearwardly from the wheel I and passes around a guide-pulley 1 which may be adjusted by means of ascrew In rear of the stemming-pulley I provide the stem-guide H and the cutter .I, both of which may be held to the frame A by the same fasteningbolts, as shown. The cutter J is in the form of a blade having its point J running in the groove of the lower stem-feeding pulley and extending to about the crown of said pulley, as shown. At its upper rear edge the cutter J extends at J between the infeedbelt F and the stem-discharging belt and guards against'such belts coming in contactwith each other.

It should be understood that the infeedingbelts F and G do not press upon the stem of the leaf, but work to one side of it on the folded leaf, also that the lower stem-feeding pulley D and the wheel I, having the stemfeeding belt I, constitute the stem-feeding device.

The stem-guide II consists of a casting or frame II, having its upper plane surface at 1-1 arranged parallel to and in close proximity to the surface of the stem-discharging belt, and the pulleys I1 of which I may use one, two, or more, as desired, suitably journaled and arranged to protrude slightly above the plane surface of the frame 11. At its point H the frame II extends close to the stemfeeding pulley in position to receive the stem when out from the leaf. In advance of the stem-feeding devices I arrange the spring K, located between the infeeding-belts and the frame A, secured at one end to the frame A and arranged at its free end to press the stem over against guide-plates L and M in position to be cut by the knife operating in the groove of the stem-feeding pulley D, where it can be acted on by the knife or cutter.

It will be noticed that the belts F and G do not run against the frame, but a space is left between such belts and the frame A for the stem of the leaf, and to hold such stem and prevent its being drawn wholly or partially between the infeeding-belts F and G, I provide the gageplates L and M, arranged alongside the inner edges of the infeeding-belts, and preferably one above and the other below the same, as shown. I also prefer to make one of the gage-plates, preferably the upper one, as shown, adjustable up and down, which may be accomplished by passing its fastening-screws through slots m.

The lower stem-feeding pulley D and the pulley I may be geared together by means of the intermediate gears N and O, meshed with each other and with gears on their respective.

pulleys, and a similar form of gearing may be employed to connect the pulleys supporting the iufeed ends of the belts F and G.

In the operation of so much of my invention as has been described the folded leaf when delivered to the belts F and G will be carried thereby to the stem-feeding devices, being held during such passage with its leaf portionbetween the belts F and G and its stem portion held by the gage-plates between such plates and the adjacent frame A. It should be stated that in so supplying the leaf it is fed tip end foremost. As the leaf approaches the stem-feeding devices its stem is engaged by the free end of the springK, which serves to keep such stem in position against gage-plates L and M, to be acted on by the knife operating in the groove of the lower stem-feeding pulley D, where it will be severed from the leaf by the cutter J when it reaches such cutter. The cut stem will then be carried by the milled surface of the lower stem-feedin g pulley and the stem-discharging belt to the stem-guide, and will then be carried upward between such guide and the stemdischarging belt until it is discharged at the top of the stem-guide. As the stem is thus carried upward the leaf from which it has been stemmed will be carried downward by I the belt-sF and G and discharged between the lower stem-feeding pulley and the rear guidepulley for the belt F. Thus, as in the hand operation, the stem is drawn in one direction and the leaf in the other and the stemming of the leaf is effectedin a thorough manner without injury to the leaf, which is held at all times during the stemming operation, and until the stem is entirely removed, between the belts F and G.

. It will be understood from the foregoing that the knife need only clip the stem, the removal of such stem being effected by the movement of the stem and leaf, one up and the other down. a

It will be noticed that the infeedingdevices, the stemming devices, and the stem-discharging devices are supported at one end by the framing A and are unobstructed at their opposite or outer ends, and this is an important feature, because, in addition to rendering the machine simple in construction and easy of access to all of its parts, it avoids any contact of the moving parts with the free edges of the folded leaf during the stemming operation, and thus prevents any injury to the leaf and permits the feeding to the machine of leaves of any size, whether large or small.

In supplying the folded leaf to the infeedbelts it is preferred to employ mechanism by which to fold the leaf longitudinally and to direct it properly to such belts, and in the construction shown I have illustrated the preferred folding and delivering devices, which include a table or support P, to which are journaled rollers 19 and p, which feed a spread leaf forward to a pair of reverselvrotating brushes Q, which brush the sides of the leaf downward on opposite sides of the stem or center, folding the leaf upon itself, and it is fed so folded between two belts R, the stem lying above such belts and the leaf-sections depending between the belts in position to move alongside a deflectorplatc S, which is twisted from a plane approximately vertical at S to ahorizontal plane at 5 so it will turn the leaf to a horizontal position when it leaves the belts R. I extend the plate 5 slightlybe: yond the delivery ends of the belts R and preferably arrange it to deliver the leaf hori zontally to the infeeding-bands F and G of the stemmingunachine.

To prevent the stem from being carried down between the belts R, I provide means which may, as shown in Figs. it and 15, con sist of the gage-plates R, located over the belts R, and extended at their f rontends forward to a point immediately below the meeting points of the opposite wheelsp p. In supplying the leaf it is placed with its stem above and its lateral leaf portion below the gage-plates and is fed in such manner to the brushes, which carry the leaf portions on opposite sides of the stem downward and deliver it between the belts It. It will also be seen that in such operation'the tip end of the leaf will also be carried down between the belts, and the leaf will be so carried between such belts R and the belts F and G, as it is desired to present the stem to the severingcutter not at the point but at a short distance back from the point.

By the described construction I provide.

mechanism whereby the spread leaf is folded, carried when so folded forward, turned at right angles to bring it into alinement with the belts of the infeeding devices, and is then stemmed in a manner closely resembling the operation now practiced by hand.

The folding devices may be geared in any suitable manner with any moving part of the stemming devices before described.
