LEAF-STEMMING MACHINE.

Application filed July 24, 1919.

The invention relates to apparatus for stemming or removing the stem or midrib from tobacco leaves as a preliminary to the manufacture of smoking or chewing tobacco, or snufi.

The objects or" the invention are to provide an apparatus which will be simple in construction, effective in operation and. economical or" manufacture and maintenance which will not become clogged. wherein the leaf will not be injured, wherein that portion of the leaf near the butt of the stem will be removed, and wherein the stem or rib will be clean and with great rapidity, and without adhering lamina portions.

These and further objects will more fully appear in the following specification and accompanying drawings considered together or separately.

Fig. 8 is a section on the line 88 of Fig. 6.

The apparatus comprises a standard 1 arried on a base (not shown) by means of which the device is carried upon a floor. The standard is provided near its upper end with radiating arms 2 preferably three in number.

The outer ends of: the arms 2 carry cone rollers 3 on which is supported an annulus 1-. The annulus is centered and retained in po sition on the rollers 3 by means of vertically journaled rollers 5. also carried on the arms 2. The annulus eicarries arms 6 on which is mounted an annular table 7.

Serial No. 812,972.

An internal gear wheel 8 is carried by the annulus at and is engaged by a spur gear 9 monnted on a Vertical shaft 10 rotatable in a casing 11 supported on one of the arms 2. A bevel gear 12 is secured to the spur gear 9 and meshes with a bevel pinion 13 carried by a horizontal shaft 14 also mounted on the casing 11. A pulley 15 on the shaft l i is adapted to be driven from a line shaft (not shown) to impart motion to the shaft and thence to the annular table 7 which is thus gien a. rotary mo -rement in the anticlockwise direction about the standard 1.

Carried on arms 16 projecting inward from the annulus d is a ring 17 on which the inner periphery of the table 7 rests. Carried by the ring 17 is a circular series of spaced, axially projecting pins 18, and between the pins and the ring 17 is an annular blade 19. The blade is seated in a rabbet in the ring 17. The pins 18 are preferably formed of half round wire and the flat sides of the pins rest against the blade 19 and are held in position by blocks 20. Each block engages two pins and is sedlired to the ring 17 by a screw. The pins project above the upper edge of: the blade 19 and the upper extremities ot the pins are bent outward as shown.

Carried on arms 21 projecting from the standard on a higher plane than the arms 2 is a. guard 22. The guard is 01" a curvature corresponding to that of the minor periphery ofthe ring 17 and extends partly around the ring as shown in Fig. 1 and is disposed directly above the pins 18 and separated from them a short distance. One end 23 of the guard 22 is arranged on a line which cuts the circle forming the opening in the table 7 and is extended downward nearly to the surface of the table as shown in Figs. 1 and 2. Carried by the curved portion of the guard 221s a series of spring fingers 24 each comprising a horizontal portion 25 on a lower level than the guard. and which normally rests against the flat sides of the pins 18 and upon the exposed upper edge of the blade 19. The end of each portion 25 is bent outward to lie alongside of and parallel to its neighbor. The spring portion 25 is immediately below the bent out portions of the pins whereby the inclined parts of the pins act to retard movement of the spring fingers away fins; 7 trance of dirt or grit beneath the heads.

from the edge of the blade, and retain the portion in the horizontal position. The horizontal. portions 25 of the springs form a continuous spring surface extending from the point A to the point B. V The table 7, and annulus et carrying the pins 18 rotate as whole, while the arms 2, arms 2-1 and guard 22 are stationary.

Mounted within the casing 11 and projecting through the top thereof is a vertical shaft 26 carrying a spur gear .ZGKdrivcn from a pinion 2? on the shaft 10 through the intermediary of an idler pinion 28 within the casing. The shaft 26 is carried in a long bearing 29 forming a portion of the casing 11.

. Keyed to the shaft 26 outside of the caring 11 is a circular turret 30 having a pcripheral recess 31. A. Cil'tjlllttl series ottubular plungers 32 is carried in the turret 30. The upper end of each plunger extends into the recess 31, and the lower extremity of each is provided with an anti-friction roller 3;. The rollers engage a camrigidly secured to the bearing 29 of the casing 11. V A spindle 34F is carried in each plunger and orojects through the upper end there of. ecured to the upper Xtre nity of each spindle is a segmental-head 85. and a spring 36 coiled around the shank of each spindle acts as a cushion for the head 35. The heads term a false bottom for the recess and are movable relatively to the bottom of the recess when the t rret is rotated relatively to the cam 31- as shown in The spindles may be adjusted by means of nuts 37.

Each head is provided with an arc-shaped groove 38 the bottom of which is inclined from the rear or minor edge thereof toward the outer edge of the head and when the heads are in position as shown in Fig. at, a-circular groove extending around the false bottom and near the periphery thereof will he formed. The upper wall of the recess 81 is provided with a dovetailed, circular groovein which is inserted an elastic, compressible ring 39. The ring 39 projects below the upper wall or" the recess and cooperates with the grooves in the heads when the latter are raised, as shown at the right in Fig. A, sleeve 4:0 is mounted on the upper part" of the casing 11. The sleeve encloses the tam 34. and the elements cooperating there with, and engages the lower portion of the turret 80 and "Forms a closed casing which may be filled with lubricant as may the lower part 41 ot the casing l1. Each of the heads is provided with depending flange which overhangs the upper end of the sleeve 40. The flanges form a skirt e:-;tendaround'ithe turret and prevent the A butter. board 42 is supported on one ol the arms 2 and on the guard 22 and tends part way around the inner periphery of the table 7 and is positioned a short distance inside of the same, and a shelf or rest s3 is carried by the butter board.

The extremity of the guard 22 nearest the point A is provided. with a plate as on each side thereof. The plates straddle the pins 18 and each plate has an inclined lower edge for a purpose to be hereinatter described, and the guard carries an adjustable cutting blade 4:5.

A sorting table 4-6 is mounted over the annular table 7 at any desired point.

The operation is as follows:

The leaves properly prepared for the stemming operation are deposited on the table l6 and the. operator takes his stand at that end of the table which lies over the annular table 2'. The leaves are arranged on the sorting table with the butt ends of the st ins towa "d the inner side of the said table.

Power applied to the pulley 15 and the table 2' and turi..t 30 are caused to rotate in the anticlockwise direction. The peripheral speed oi? the turret will be considerably less than that of the inner edge of the table.

T he operator will place the leaves one at a time on the rotating table '1' each with its stein rest ng between two or" the pins 18 and the butt end of the stern in engagement with the butter board That portion of the stem between the pins and the butter board will rest upon the shell 43 and be prevented'from sagging. The rotation of the table 7 will carry the le es toward the turret 30 and as the stems pass under the guard QQ they will engage the lower, inclined edges of the plates ll and be depressed into engagement with the upper cdge of the annular blade 19.

The continued movement ot" the table 7 will bring the stem under the horizontal portion :25 oi the first spring finger which will be raised by the stem. The upward movement ot the finger is resisted. by the inclin d bend of the fingers, and the stem is held n the gap between two pins, the blade 19 and the tinger'24. The stem will remain in tlie said gap until it is finally withdrawn. As the table .irries the leaf further in its travel. that end of the stem projecting inward oi the pins will be directed, into the recess Sl oi the turret 30. The rliitation of the turret so timed relatively to the table and to the cam that as the heads approach the table at the point A, where the periphery of the turret in proximity to the inner oori 'iherv otthe table and to the sins 18.. the heads are at the lower-most point oi their movement; The end of the stem is therefore inserted in the recess be the stem will be clamped betw en the head and the ring 39. The ring being of soft rubber or other compressible material, will be compressed by the stem but the portion of the ring at each side of the stem will con tact with the inclined bottom of the groove and be bent or crowded inward toward the axial line of the turret. This will tend to draw the stem inward and supplement the clamping effect of the head on the stem and prevent its withdrawal from the recess.

As the periphery of the rotating turret begins to travel away from the pins after passing the point A the stem will be drawn through the gap between the pins while the lamina will beprevented from passing be cause of the pins; and the pressure of the spring lingers 24 willforce the stem against the blade 19 and the fingers and blade will also tend to prevent the passage of the lamina.

When the head engaging the butt of the stem reaches the point C diametrically opposite the point A the tip of the longest stem will be at the point B and the stem will be wholly withdrawn from the lamina, which will then be forced off the table 7 by the eX- tension 23 of the guard 22.

V] hen the head engaging the butt of the stem reaches the point C the cam groove will depress the plunger 32 and head 35 and release the stem, which will fall out of the recess of the turret.

If it is desirable that a portion of the stem near the end thereof be retained in the lamina the knife is placed in position on the guard 22 and as the stem is borne under the knife it is severed and the thin end remains in the tip of the lamina. The knife may be adjusted to cut off as much or as little of the stem as desired as it is adjusted toward or away from the point A.

By changing the proportions of the gear chain 26. 2'7 and 28 the speed of rotation of the turret relatively to that of the table may be varied and the machine adjusted to operate on long or short leaves.

The gap through which the stem is drawn is al ays rectangular being bounded by. two of the pins '18, the edge of the blade 19 and a spring finger 2i25,' and these four elements will always be in position to prevent any partof the lamina from being drawn through the As the stem is drawn through the gap its diameter grows gradually less, but the elasticity of the spring fingers supplemented by the resistance to upward movement by the outturned ends of the pins 18 will hold the fingers in cont-act with the stems until the latter are wholly withdrawn from the lamina or are severed by the knife 45.

The outer faces of the pins 18 being fiat, and the'edge of the blade being either flat or sharpened. as desired, will present more or less sharp edges to the stem and the lamina will be scraped from the stem instead of the stem being torn from the lamina as in the present forms of stemming machines.

The wire of the fingers 2t 25 may be, and preferably is, of angular cross section so that there will he formed sharp edges to scrape the lamina away from the stem, and the latter will be removed from the lea cleaned entirely from any part of the lamina.

The spring cushions 36 of the heads 35 and the yielding ring 39 will prevent the stem from being out or broken off by the withdrawing mechanism.

The fa that the end of one spring finger overlaps the next finger insures the stem being always under a finger and held in engagement with the edge of the blade 1.9.

The periphery of the turret 30 at the point A where the butt of the stem is taken is in c se proximity to the pins 18 and when the m is received in the recess 81 the lamina always will be on the opposite side of the pins and when the stripping begins as the peripheries of the turret and table 7 move a ray from each other, none of the laminae will adhere to that portion of the stem between the pins and the head grasping the butt of the stem.

The speeds of the table 7 and turret 30 are constant during the operation, but because ot the difference in diameter of those elcn'ients the speed with which the stem is withdrawn from the lamina will increase gradually as the inner periphery of the table recedes from the periphery of the turret. This movement of the table relatively to the turret will cause the stem to be drawn diagonally through the gap between the pins whereby the angular edges of the pins will have a more effective scraping action on the stems.

As the pins rccede from the turret by the rotation of the table and the angularity of the gap relatively to the point on the turret at which the stem is grasped increases, and the stem is drawn diagonally through the trap, the effective width of the gap decreases. This decrease in the gap width will correspond more or less with the gradually re ducing diameter of the stem as the point of the leaf is approached. and the spring fingers pressing down on the stems at all times will insure the scraping of the stem on four sides all times irrespective of the size of, the stem.
