To all whom t may concern:

Be it known that l, MARTIN DEILLER, a

citizen of France residin at Newark in the county oic Essex and Stat-e of New Jersey, have invented. certain new and useful lmprovements in Tobacco-Strippers; and I do hereby declare the following to be aull, clear, and exact description. of the invention, such as will enable others skilled in ,the art to which it appertains to make and use the same, reference being had to the accompany# ing drawings, and to numerals of reference marked thereon, which form a part of this specication.

This invention relates to certain improve# ments in Ithat class of tobacco-stripping Inachines shown in my prior patent, N o. 716,627, issued December 23, 1902, the objects of the present invention being to secure amore compact machine, to enable a cylinder or drum to be employed instead of a ilat table, to thus combine the booking device with the table, to provide an improved registering attachment, to secure suitable intermittent action of the diilerent parts, and to obtain other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

lThe invention consists inthe improved toe bacco-stri ping machine and in the arrangements an combinations of parts of the same,

all substantially as will be hereinafter set forth, and iinally embraced in the clauses of the claim.

Referring tothe accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several iiguree, Figure `1 is a plan of my'improved maclnne. Fig. 2 is a side elevation of the same. Fig. 3 is an elevation of the machine from the front end. Fig. 4 is a vertical longitudinal section taken upon linea, Fig. 8, lo'oking in the direction indicated by the single arrow; and Fig. 5 is a similar view of a portion of the machine looking in the opposite direction as indicated by the double arrow on line ce, Fig.

8.` Figs. 6 and 7 showin edge view and lan,

, respectively, certain leaf-holding fingers erevinai-ter described. Fig. 8 is a transverse ver' tical section-of the machine upon line Fig.

o. Fig. 9 is a side view of the forward part of the machine, showing the registering attachment in detail; and'Fig'. 10 illustrates another position of the parts of said registering apparatus. Fig. 1l shows the registering apparatus in edge view. 12 1s a A between themselves the working parts of the i 5 5, each having circular end pieces 6 6 and. a

plan of a certain sliding trip or catch. Fig. 13 is a section of the saine upon line y, Fig. 12. Figs. 14 and 15 are detail views of the rotary cutter in side elevation and edge view and illustrating a slightly-modified construction; and Figs. 16 and 17 are sectional views of said cutter, taken on lines z and 2', respectively, of Fig'. 14, looking in the directions indicated by the arrows.

In said drawings,I 2 2 indicate the side frames or plates of my improved machine, which are vertically arranged parallel to each other at a suitable distance apart to receive machine, which will be hereinafter described.

I Between said plates extends a main or drum shaft 3, upon which is mounted a drum or cylinder 4, comprising longitudinal sections curved peripheral portion 7. AAt the inner adjacent ends of the sections each is provided with a iiange 8, projecting radially beyond the outer surface of the drumsection, said flan es being at their edges beveled each to- War' its drum-section to present sharp cutting edges 9 9. Around the said drum or cylinder 4 are arranged belts 10 to hold the leaves in place upon said drum-sections, each drum-section reicrably having three of these belts. Each Felt is carried around the under surface of the drum, as at 11, Fig. 2, over an p upper ulley 121 at the front of the cylinder 4 and t en downward at a distance from said cylinder over rollers 12 13 beneath the cylinder and upward over rollers 14 15, the latter roller 15 being adjacent to the cylinder 4 at the upper part of its rear portion. The` beltsl are thus doubled around the drum, the inner fold lying against the lower part of the same and the outer fold being carried u on pulleys and heldv taut by means of the pu ley 13, being journaled upon one end of the bellciank lever 16, having a weight 17 at the other end and at its bend a fulcrumal pin 1,8, coniined in a slot 19 of a fixed. arm 20, rojecting from rthe Aiirame of the machine. hus as the leaves are put into the machine, one at each revolution of the drum, they are held by said belts and become superposed one upon the other toform a book, the Weight 17 being lifted as the book thickens. Each belt, it will be understood, 'is independent of the others, and the number or width of the belts may be varied at pleasure.

Each leaf is inserted with its ti first, as shown in Fig. 1, the mid-rib of the eat being IOO IIO

between the flanges 8 of the two drum-sec-` one of the drum-sections and the rib is eut out by a cutter 21, cooperatingl with the sharp edges 9 9 of the flanges 8. Said cutter is stationed at thcfront of the machine or forward side of the cylinder' 4 and comprises a series of curved blades 22, (see Figs. 4, 14, 17 projecting radially from ahub 23, mounted upon a transverse shaft 24, journaled in the side .frames 2 parallel to the'main or drum shaft 3 and adapted to be rotated by means hereinafter described. Said blades are each formed byan arm or bodyportion 25, wedgeshaped in cross-section, the thicker part being at the forward or curved edge of the blade and having upon the opposite sides of said bodyportion knives 26 26, which thus diverge forwardly and project beyond vthe body part of the arm. Moreover, a portion of the arm near the hub and which first enters the slot between the flanges 8 S., is narrower or thinner than the part farther out from the hub, whereby the entrance of each blade between the flanges is facilitated and a shearing action insured. The leaf-rib thus cut out passes inwardly between the drum-sections 5 5 and is directed downward and outward by a guide 27, projecting into the said space from point below the cylinder. A series of rotatingfarms 28 are also provided to enter said slot between the drum-sections and aid in dislodging the leaf ribs or stems therefrom so that they fall to the fioor.

The drum-sections 5 5 are preferably one fast on the shaft 3 and the other slidable and held toward the first by means of a spring 29 on said` shaft between the drum and side frame. Tie-rods 30', of any suitable type, are of course provided to hold the side frames in rigid relation.

At the upper part of the front of the machine just back of the roller 12 for the belts 1() is arranged, between the side frames 2 2 of the machine, a transverse shaft 31, having 32, which exat its central portion an arm tends toward the drum 4 and is bifureated at' its end. Each arm or bifurcaticn of said arm 32 carries a guide-strip 33, adapt-ed to lie against the leaf adjacent to the flange S of the drum and hold'the said leaf down against said drum.y Said strips 33 are preferabl)Y connected by rollers 34, extending across the flanges 8 and cutting edges 9 of the drum, and the forward ends of said guide strips are curved upwardly, as at 35, to facilitate the insertion of the leaves. serve to hold the ribs of each leaf against t ie cutting edges Q 9 of the drum as the leaf en ters the machine, and resiliency of such holding is secured by a spring 36, attached at one end to the said frame 2 of the machine and at It is necessary while the leaves are in the These guide-stripsv tion of said leaf is not impeded, it being un-` derstood that the drum pauses momentarily for such insertion ofthe leaf and that as soon as rotation again commences the fingers 3S close upon the leaf. To this end each drum'- seetion has arranged upon its shaft 3, inside the drum and adjacent toA the cutting end thereof, an arm 39, which projects upward to or nearly to the peripheral wall of the drum- Section and provides thereat a slideway 4() for the stem 41 of theclainping-finger 38,

the drum and the finger being extendedforwardly and curved to fit the drum-surface. Said stem 41 is held retracted, preferably, by means of a spiral spring 42, engaging a stop 43 at the end of the stem and 1at its other end abutting against the slideway 4f). Upon one side of said slideway, as at 44, is `fulcrumed a bent lever 45, one arm of which,` as 46, engagesthe stem 41 of the said finger and the other arm 47 of which is adapted as the drum rotates to engage a fixed pin 4S upon a suitable support 481 from the side frame?. Said pin 48 is so arranged that it will be .engaged by the said bent lever just before the drum comes in position to receive a new leaf, the said bent lever being operated to raise the fingers 3S and hold them raised whilelthe drum comes to a stop, as hereinafter described. 'lhe freshl leaf is then inserted, and as the drum starts up again thelevcr 45 is freed from the pin 4Sand the lingers grip the leaves. lt will be understood that there are two of these.leaf-holding fingers 31S, one o n either side of the slot between the drum-sectionsfand that the sant` 1na be of an \v desired shape,. although, preferably,l quite broad, as shown in l* 6 and 7. By the construction described it will be noted that a movement of the said holding-fingers in a di'- rection exactly perjnndicular to thi` surface of the drum is secured.-

On one end of the main or'druni shaft 3 outside the side frame of the machine is xed a sprocket 49, and at the lower part of the machine is a transverse driving-shaft 50, journaled' in the side frames and carrying a dri inw-sprocket 51 from which a chain 52 transmits motion to the drum-shaft sprocket 49.

above mentioned. Said shaft 50 is driven b v a belt-prille)v 501 or in any other suitable inanv ner, and the said sprocket-wheel 51, which carries the chain to the drum-shaft Si, is prel-v erablv adapted to be connected to or disconnected from said shaft 5() by clutch means .85 said stem protruding through the surface of v IOO IIO

next to be described. Said sprocket 51 is normally loose upon the shaft 50 and at its side next the machine is provided'with an ani nular series of teeth 53, adaptedto be enf" gaged by pawls 54, rotating with the'shaft- Said pawls are each pivoted in radial position" with respect to the shaft upon a supportingspider 55 and at their ends next the shaft are connected, as by links 56, (see Fig. 11,) to a vtion to the sprocket 51.

sleeve 57, slidable on the shaft. A spiral spring 58,-coiled upon the shaft, serves to normally force said sleeve away from the s i-'- lower arm of a bell-crank lever 62, pivoted upon the frame of the machine beneath the same, and being normally held by a spring 63 with the sleeve 57 away from the pawls. A controlling-lever 64, also pivoted upon the frame of the machine, is adapted to engage the other arm of the said bell-crank lever 62'v ,i

and swing the same against the power of its spring 63, said controllin -lever having at its endaway from the sai bell-crank levera rod 65, which extends upward and is connected to a latch 66, (see Fig. 9,) adapted to be tripped by a pin 67 upon a disk 671on the drum-shaft 3 at each revolution thereof.

rSaid pin is stationed at a point such that the said latch 66 will be tripped and the clutch thrown out of engagement to stop the rotation of the drum when it is in exactly the right position to receive a fresh leaf. As soon as the leaf has been inserted the latch 66 is released from the pin 67, as hereinafter described, Iand the clutch therefore thrown in again to rotate the drum.

Preferably a treadle 68, convenient to the operators foot, is connected by a link 69 with the bell-crank lever 62 from beneath so that i said operator can at any momentthrow the clutch and stop thegdrum. The latch 66 is made in two sectiond 70'71, the section 70 beingflcrumedupon a stud 72 and providing ways for the other section 71 to slide longitudinally upon said firstl mentioned section v70. Ears 73 74 project from the sections, between which ears is arranged a spiral spring 75, normally holding the sections in extended relation. A rod `76,

' passing through the ear 73 on the fixed section and through the spring 75, is secured to the ear 74 of the slidable section, and this rod has a turned or hooked outer end adapted tobe slidably engaged by an arm 77 of a transversev shaft 78 ofthe machine, said vshaft having another arm 79, from which a conmeeting-rod 80, extending to a second treadle 31, preferably mounted on the same shaft 82 with the first-mentioned treadle 68. By this vsecond treadle 81 and its connections the operator releases the latch 66 after a new tobaeco-leaf hasbeen'fed onto the drum to again throw in the clutch at the drivingsprocket 51 and start the drum rotating.

' To enable the number of leaves stripped and booked upon my improved machine to be registered,k I apply to the latch 66 the following registering means: The stud 7 2 upon which said latch is pivoted has also pivoted thereon concentric with said latch andoutside the samea disk 83 and at the inner side thereorifa smaller ratchet-wheel 84.y Springpressedfpawls 35 are carriedby :the latch 66 to engage said ratchet-wheel, and thus as the Obviously a registration upon any revolutionof th drum may be avoided, if. desired, by retracting the latch 66 from the path of For driving the rotary cutter 21 I have shown upon the drum-shaft 3 a gear 89, intermeshing with a smaller gear 90 upon the cutter-shaft, and for rotating the stemclearing arms 28 the shaft 91, upon which said arms are mounted, is connected by a sprocket-chain 92 with the driving-shaft 50.

IOO

Obviously, however, any other suitable driv- A ing means might be employed.

A forward portion Iof the frame, in which the cutter 21, guide-strips 33, andbelt- rollers 12 and 121 are journaled, is hinged, as at 93, so that it may be tipped away to ermit access to the drum, as shown in out ine in Fig. 2. A hinged shield or guard 94, is also provided at the rear of the machine to cover the belt-pulley 15 and close in the interior mechanism.

Having thus described the invention, what I claim as new is- 1. The combination with a Ldrum presenting'a circumferential slot with=cutting edges on opposite sides thereof, and means for holding tobacco-leaves thereon, of a rotary cutter having a series of radial arms adapted to turn in said slot, each arm comprising a bod portion flarin both from the hub radially outward 'and om its rear edge toward the forward edge, and knife-blades mounted on the sides of said body portion.

' 2. The combination with the circumferentially-slotted drum, and means for holding ing a body portion vwedge-sha ed in crosssection, with its widest ed e orward, and knife-blades mounted on t e sides of said body portion. l 3. In a ,tobacco-stripping machine, the combination with a rotary drum, circumferentially slotted to receive the mid-rib of a leaf, and means for rotating said drum of curved pressure-strips adapted to lie against the drum on opposite sides of said slot, and means forresiliently supporting said pressure-strips.

4. ln a' tobacco-stripping machine, the combination withy a rotary drum, circumferentially slotted to receive the mid-rib of a leaf, and means for rotating said-drum, of

curved pressure-strips adapted to lie against the drum on opposite sides of said slot, rollers mounted upon said strips and lying between the same and across the drum-slot, and means for resiliently supporting said pressure-strips.

5. ln a tobacco-stripping machine, the combination with a rotary drum, circumferentially slotted to receive the 'mid-rib ofI a leai, and means for rotating said drum, of a resiliently-supported arm extendin, toward the drum in the plane of its slot and eing biurcated adjacent to said slot, a curved pressure-strip u on each bifurcation of said arm, adapted to ie against the drum at one side of its slot and having'its, forward end curved outward, and rollers mounted between and .upon said pressure-strips and extending across the slot of the drum.

6. In a tobacco stripping machine, the combination with a drum and means for imparting to saidI drum an intermittent rotary motion, of leaf-holding fingers normally iying against the surface ci? the drum, supporting means permitting said fingers to move away from the drum lbut always retaining their parallel relation thereto, and trippin means adapted to raise said fingers just be ore the e1 ases drum stops in its rotary movement'and release them just as the drum starts again.

7. The combination with the drum' adapt- .adapted to raise said fingers away from the 4drum at predetermined intervals.

8. In a tobacco-stripper, a frame, a shaft, a drum on said shaft and means for turning the same', an arm on .the shaft providing a radial slideway, a stem in said slideway, a clamping-finger upon said stem outside the drum, a sprinrr normally forcin ward the shait, a bent lever icrumed upon the drum and adapted at one end to engage said stem, and a pin upon the frame adapted to be engaged by the other end of said lever.
