SPECIFICATION forming part of Letters Patent No. 510,895, dated December 19, 1893.

Application filed December 16, 1892. Serial No. 455,367. (No model.)

To all whom it may concern: A

Be it known that I, ANDERSON BLAGKWELL COSBY, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented a new and useful Tobacco-Cutter, of which the following is a speciication.

This invention relates to tobacco cutters; and it has for its object to provide certain improvemen ts in that class of machines whereby either plug or leaf tobacco can be cut into iine pieces or cuts, for the purpose of smoking or chewing.

To this end the invention primarily contemplates an improved tobacco cutter having special feed-devices and adjustments whereby various cuts can be accurately had.

Vith these and other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings-Figure 1 is a side elevation of atobacco cutter constructed in accordance with this invention. Fig. 2 is a side elevation from the side opposite to that shown in Fig. 1. Fig. 3 is a central vertical longitudinal sectional view of the machine. Fig. 4 is an end view. Fig. 5 is an enlarged elevation of one of the side plates of the movable feed box or trough, corresponding to the one shown in Fig. 1. Fig. 6 is a similar view of the opposite side plate of the feed box or trough plate corresponding to the one shown in Fig. 2. Fig. 7 is a detail sectional view on the line 7-7 of Fig. 2. Fig. 8 is a detail plan viewr of the construction shown in Fig. 7. Fig. 9 is a detail sectional view partly in elevation of the pawlactuating mechanism. Fig. 10 is a detail view of the lower positive stop or check pawl.' Fig. 11 is a detail sectional View of the fast pulley and the connections therewith.

Referring to the accompanyingdrawingsz- A represents a suitably connected metallic frame, or casing comprising the opposite inclosing side frame pieces a, which support and accommodate the various parts of the machine.

Arranged at the upper corners of the side frame pieces a, and at one end of the same are the opposite removable bearings B. The

bearings B, have the extended plates b, bolted to the inside of the frame pieces a, andare further provided with the laterally extended bosses b', the inner ones of which loosely receive the outer perforated ends b2, of the opposite hinged feed-box or trough plates C. '[he opposite box plates C,are thus pivotally mounted or hinged at their outer ends to the opposite bearings B, so as to leave their inner ends. free to move up and down,and said plates C, are held spaced from each other and securely on their points of pivot so as to be free to move up and down within the frame A, by means of the feed table c. The feed table c, is provided near its outer end with the opposite cleats c', which embrace the transverse oscillating eccentric shaft c2, the opposite ends of which find a bearing in the opposite bearings' B, and which is further provided at its opposite ends with the eX- tended reduced spindles c3, the function of which will be hereinafter morefullydescribed. The feed table, c, referred to, has its inner end beveled as at c4, so as to loosely rest on one o f the feeding rolls to be described, and it will be apparent that the saidv feeding table together with the opposite plates C, form an inclosed feed box or trough which serves to feed the plugs or tobacco leaves to the cutting devices.

To the innerends of the opposite box-plates O, are pivotallyy connected the upper ends of the lever links D, the lower ends of which are pivoted to the opposite weighted lever arms d, near their points of pivot at d. The said opposite Weighted lever arms d, are pivoted at one end to the opposite frame pieces a, at CZ, and have their outer swinging ends connected by the weight d2, which normally depresses the free ends of said lever arms and through the medium of the linksD, normally holds the inner end of the feed box or trough on the rotary chopping block d3, in the manner to be described. Said rotary chopping blockd, has the usual wooden peripheryand.

is mounted on the revolving shaft d4, journaled in opposite sides of the frame pieces a, and carrying at one end thereof theA large gear wheel d5 through which motion is transmitted to the block, when the machine is in operation. When cleaningA the machine, the

IOC

inner connected ends of the feed box or trough can be lifted above the chopping block, and held so, by means of the lifting chain E, connected at one end to the weight d2, and at the other end to the transverse winding shaft e, which shaft is journaled transversely through the frame A, and earries at one end the hand wheel c', by means of which the shaft can be turned, and which may be held from turning by means of a suitable pin e2, passed between its spokes into a perforation or opening in one of the frame pieces a.

Within the feed box or trough at the inner end of the bottom or feed table c, are the bottom feed rollsl` and F', respectively,the first feed roll F, being larg er than the feed roll F', and in a slightly lower plane than the same, so that the tobacco passes directly from the table c, onto the larger feed roll F, and from thence is elevated to a higher plane over the smaller higher roll F', which serves, together with the other feeding devices to be described, to bring the tobacco intoa proper position to be received by the chopping block and be carried to the cutting devices. Both of the lower feed rolls F and F', are longitudinally corrugated and each is mounted on a transverse shaft f, the opposite ends of which project through slots f', in the box plates C, and are journaled in suitable bearingopenings in the opposite adjustable lower roller plates G. The opposite lower roller plates G, are suitably conneeted and braced by a stay rod g, and the hinge or pivot rod g', which connects one end of said plates, and serves to pivot the same at such end on the outside of the plates C, thereby leaving the other ends free to move, and such other ends are provided with curved under edges g2, against which work the opposite adjusting cam levers g3. The opposite adjusting cam levers g3, are provided with suitable handle ends by which the same are manipulated, and are pivoted to the box sides c, at g4, said levers having at their pivoted ends the laterally extended eccentric portions or heads g5, which contact with the under curved ends of the lower roller plates, so that as the' said eccentric heads are thrown to either side of the center or point of pivot, the said lower roller plates are correspondingly raised or lowered so as to properly adjust the lower feed rolls with respect to the upper feeding devices.

At one end of the roll shafts f, are secured the adjacent gears H, which are connected by an intermediate connecting gear h, which is arranged above and between both of the roll gearsand is mounted on a suitable journal projecting from one of the plates G, and said intermediate gear h, also meshes with a supported gear h', which is journaled on the connecting pin or bolt h2, which connects the upper ends of the gear supporting links h3, the lower end of one of which is pivotally connected to the plate G, back of the intermediate gear h, while the lower end of the other link is designed to be loose on the bearing of the second, intermediate or auxiliary gear h4. The second intermediate gear lt, meshes with the supported gear h', and is mounted on a suitable stud, journal or rod, extending from one side of one of the box plates C, and arranged in front of said second intermediate gear is one end of one of the suspendinglinks I, l', The link I, in front of the gear h4, overlaps and is connected to the same point as one end of one of the links h3, and the other end of said link is connected to the lower end of the link I', by means of the journal pin z', on which is mounted the suspended gear wheel i. The gear wheel ',meshes with the wheel h4, and the upper stationary gear wheel or pinion 2. The upperstationary gear Wheel or pinion i2, is mounted on one end of the transverse drive shaft Z3, the bearing at one end of which forms a pivotal support for the upper end of the link I'. Motion is communicated to these several gears through the ratchet mechanism hereinafter described, and by reason of the two link connections 'for the supported and suspended gears it will be seen, that, as the lower feed rolls are adjusted, as described, and as the feed box or trough adjusts itself, the several intermeshing gears adjust themselves to each otherwithout any unnecessary binding orl friction to interfere with the free operation of the maehiune.

Pivotally mounted at their innermost perforated ends on the outside of the opposite bearings for the transverse shaft t3, are the opposite adjustable upper roll plates JL The upper roll plates J are thus pivotally mounted or hinged at one end so that their other ends are free to move outside of the opposite box plates C, above the lower roll plates, and such other free ends are pivotally connected, by means of the linksj, to the eccentric heads of the eccentric lever arms j', similar in construction to the lever arms g3, and adapted when thrown to either side of their centers or points of pivot, to raise and lower said plates and theseveral upper feed rollers K, K', K2 and K3, respectively. The several upper feed rolls are longitudinally corrugated similar to the lower feed rolls, and are mounted on the transverse shafts L, which have their ends journaled in the opposite roll plates J, and are adapted to be arranged above the upper edge of the opposite box plate C, so as to have a free vertical adjustment, and said shafts carry upon one end thereof, outside of one of the movable roll plates J, the adjacent gear wheels L', between which are arranged the intermeshing gears Z. Theintermeshing gears Z, are journaled upon one end of the stay rods Z', which connect the two upper roll plates with each other and accommodate the spacing sleeves Z2, usually placed upon stay rods, and one of said intermeshing gears Z, also meshes with the fixed gear wheel Z3, mounted upon one end of the drive shaft 53, on the end opposite the stationary gearwheel or pinion Z2, which receives its motion from IOO the gear wheel i', before referred to. When the train of gearing just described is in motion, the upper and lower rolls turn in the same direction so as to positively and accurately feed the tobacco toward the cutting devices, and by reference to Fig. 3 it will be seen that the upper rolls K and K, are in different planes corresponding tothe disposition of the lower rolls F and F', and are arranged directly above such lower rolls so as to form a narrowing passage for the tobacco, and to insure the feed therefrom positively between the nearest rollers K', and F. The other upper feed rollers K2 and K3 are practically in the same plane with each other but in a lower plane than the rolls K and K and and such block the tobacco is fed, the weight depressed box or trough lifting to accommodate the tobacco as will be apparent.

The ledger blade or bar M, connects the inner ends of the opposite box plates C, and is provided with the opposite right angularly disposed anges m, bolted to said plates, and said blade or bar, as stated, is normally held in contact with the wooden chopping block by means of the weight cl2. The said stationary blade or bar carried by the weight depressed feed box or trough is smoothed at its front edge as at m', and beyond which the feeding devices project the tobacco so as 4 to be cut by the knife N, traveling against and in front of said blade or bar. The knife, is clamped in a suitable knife head or stock fn, to one side of which is pivotally attached the connecting links n', the other end of which engages the central crank of the knife crank shaft O, which serves to reciprocate or give the knife its up and down movement. The vsaid shaft carries upon one end the balance wheel o, and at the same end the slotted crank arm o', while to the other end of the shaft is attached the loose and fast pulleys o2 and 03, respectively, which are designed to receive `the drive belt o4, which passes through anv adjacent U-shaped belt guide o5, attached to one end of a suitable bar o6. The crank shaft O, is journaled in suitable bearings at the upper ends of the opposite bearing arms or uprights P, extended from the opposite side frame pieces a, and asthe same revolves it communicates a reciprocating motion to' the knife, so that the same travels up and down in front vof the ledger blade or bar, to shave off the tobacco as ne as desired, which is regulated by the feeding devices of the movable feed box or trough. The knife N, is held' steady in its reciprocations and out of yinterference with the inner end of the feed box or trough by means of the opposite swingingknife arms Q. The free ends of the knife arms Q, are pivotally attached'to 'opposite lsides ofthe knife stock while the other ends thereof are loosely mounted on the reduced spindle ends c3, of the oscillating eccentric shaft c2, journaled in the frame bearings B. The swinging knife arms Q, not only swing to hold the knife to its reciprocating movement, but also have a longitudinal vibratory movement which is imparted to the same by the oscillation of the eccentric shaft c2. An oscillating motion is communicated to the eccentric shaft by means of a swinging or vibrating arm R, one end of which is adj ustably bound to the extremities of the spindles c3, by means of the set screw o", while the other free end of the arm carries the sliding stud r', working in the lower slotted end of the connecting bar r2. The connecting bar r2, is adj ustably connected to the slotted crank arm o', at one end of the crank shaft O, by means of the bolt r3, and the other end of said connecting bar is threaded to receive the adjusting screw r4, which is loosely connected to the stud r', so as to adj ust the free end of the armR, on said connecting bar. Now it will be read-ily seen, that, as the crank shaft rotates, and carries the slotted crank arm therewith, the connecting bar r2, raises and lowers the free end of the arm R, which thereby oscillates the eccentric shaft back and forth to give the knife arms areciprocatingorlongitudinal Vibratory movement. This additional movement of the knife arms, serves 'to impart a lateral vibration of the knife to and away from the ledger blade or bar in addition to its reciprocating movement. The knife is therefore given a combined vertio'al-reciprocatory and lateral-vibratory movement, so that justbefore the knife begins to descend, the same is drawn toward the ledger blade or bar so as to work there-against to cut the tobacco, and after having passed through the tobacco and against the chopping block, the eccentric has turned so as to throw the knife away from the ledger blade or bar during its ascent. The extent of this lateral vibration of the knife can be regulated by adjusting the bar r2, inthe crank arm, which serves to increase or reduce the throw of the eccentric. As the ledger blade or bar wears away thethrow of the eccentric can be shifted to oscillate from a diiferent position in its bearings, by means of adjusting the connection of the arm R, with the bar fr?. This will be apparent.

Journaled in a bracket extension S, at one IOO side of the frame A, is the ratchet wheel shaft s, carrying at its outer end the -actuating ratchet wheel T. Motion is communicated to the ratchet wheel T, by means of the spring actuated pawl z, carried by the swinging pawl arm t'. The swinging pawl arm t loosely embraces the bearing for the shaft s, alongside of the wheel T, and accommodates the turning pawl rod z', carrying at one end the pawl 2, and at its other end the spring box or housing t2, secured on said rod by means of the set screw t3. A pawl actuating spring t4, is entirely inclosed within the box t2,`so as to be free from dirt, grit and dust, and has one end thereof fastened toy said box and the other end to the pawl' arm so that the pawl ,5, is a1- ways positively in engagement with the teeth of the ratchet wheel. The free end of the pawl arm t', has pivotally connected thereto the connecting arm U, the other end of which is pivoted to the feed adjusting bar u. The feed adjusting bar fu., is pivoted at one end to the outer face of the fast pulley oa, and carries at its other end a iianged stud bolt u', adapted to work in the graduated curved slot u?, in the outside face of the fast pulley 03'. The outer end of the flanged stud bolt receives the binding nut u", which serves to bind the bar u, tightly against the face of the fast pulley to hold the same in any adjusted position and thereby regulate the swing ot` the pawl arm, and therefore the feed of the ratchet wheel. When the pawl, z, issecuring a new hold on the ratchet wheel, the same is prevented from slipping by means of the positive stop or check pawl V. The stop or check pawl V, is pivoted at one end toa suitable point of attachment at one side ofthe frame a., below the ratchet, and is normally held in engagement therewith by means of the spring o, connected thereto and to a suitable point of attachment.

The ratchet wheel shaft s, carries atits inner end the pinion W, which pinion meshes with an adjacent gear wheel w, which is mounted on a` counter-shaft lw'. The counter-shaft w', is mounted in suitable bearings below the ratchet wheel shaft and carries on both sides of the gear wheel w, the pinions w2 and w3, the first of which, to2, meshes with the large gear wheel d5, whichv communicates motion to the rotary chopping block, while the other pinion meshes with the gear wheel t, so as to communicate motion to the several feed roll gears herein described. It will of course be understood that dierent sizes of ratchet wheels` T, may be employed according to the nature of the work to be accomplished.

From the foregoing it is thought that the construction, operation and many advantages of the herein-described tobacco cutter will now be apparent. It will be seen that the tobacco which is .fed onto the feed table of the feed box or trough passes between the several corrugated feed rolls, on` the line shown in Fig. 3 as the feed line, and as the ratchet devices intermittently turn the several feed rolls and the chopping block, a cer- The various adjustments of the knife and feeding mechanism has been set forth.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacricing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
