Be it known that I, JOHN IVI. DEAN, a citizen of the United States of America, residing at Grrandv Rapids, in the county of Kent and State of Michigam have linvented certain new and' useful Improvements -`in Tobacco Stemming and Booking Machines; and I do hereby declare the following to be a full, clear, and eXact description ofthe invention, such as willenable others skilled n n the art to which it `appertains tomake and use the same. p l v This invention relates tok tobacco stripping and booking machim-isk and has, for its primary object andfpurpose theprovisionof a machine which will `strip the stems from the leavesof tobacco and at the same time book the parts ofthe leaves from which the stems are removed. 'A further objectof 'the invention is to provide a machine of this character in which the stem of. a leaf is fed into the machine and cutting knives brought against the leaf each side of the stem whereby as the leaf is carried into Vthe machine,

a severing of the stem therefromis accom plished, the stem beingfejected from the ma# chine and the remainder of the'leaf carried around a-drum on whichit' remains, succeeding lleaves lbeing booked one over the other on the drum.- Various other objects and purposes, including mechanisms foi-.

controlling the machine, for stopping the same either `automatically or at will,"for

grasping the end ofthe stem to positively feed the leaf into theinachine, for elevating the front part of the machine'for' removal of a pack or book of leaves, and for accomplishing many other novel operations notI specifically enumerated. at this time, will ap# pear as understanding of the invention is `v had from the following description taken in connection with the accompanying drawings.

At their v`front ends arms 8 4carry .a shaft 97. eWheels or pulleys 12 are rotatably mountedonfthe rod 47, while similar wheels orpulleyls '11 'are fixed on the shaft 97, .one on eaclifsidefofa grooved wheelialsovfixed on said'shafft 97.

The arms 108 project downward at aninclination and extend `below the planeof the arms 109 which are approximately horizontal. rlhe lower edge of the feed-.wheel extends into the slot between plates 69 and 70,1nhile at its upper portion it extends intdthe groove ofthe wheel 35, beingdriven thereby. Extensions 108 are made to the arms 109 yin front, the same carrying a smallproller 16 forbearing -upon the stem of a leaf ofto bacco as it is startedunder `the feedwheel. It is apparent that'the .entire mechanism mounted atthe lower end ofthe arm 'Qinay vbe .elevated into the dotted `line position shown in Fig. 7 or 10 by merely grasping the front fportion of the mechanism and pulling hard i enough to disconnect the -rod 47 from .the spring actuated plugs .104 in which the ends of `said rod seatgland Athat v ing the adjustment andthe/ Ii tightening said :set screws.Y l f l These arms are secured in 'fixed posij fend on one side of the supportp.

Vlhe arms 22 `and '34 serve in the capacity of belt tensioners,it\being designed that ythe samemay ybe operated kby lsprings..` Drum 6 is driven iby the belts. thereafter the device may be returned to Two othergbelts A pass around rollers :17,

18, 21 and 13, thence under the drum 6, being located outside lofthe belts B and driven in .unisontherewitlr lSaid belts'ii and B are A through the head 7 isa` narrowbelt-73 of leather in which a lurality of notches'73FL are cut as shown iniliig. 3. The belt is cut atits upper portionat veach side at angle and is provided with a central upper'groove 73b as shown in F ig. 6, this construction precluding interference of the belt with the cutting knives, hereafter described, and aiding in receiving the steml of the leaf of tobacco fed into the machine. This belt passes around a drivingk roller 101, iiXed on i a shaft 100, thence downwardly and forwardly under a tension roller 86 carried at the lower end of,A a` depending pivotally mounted arm 90,'thence upwardly overa roller 87 suitably mounted on a projecting part 88 of the main support, and thence to the rear through thehead 7. The belt 73 is pressed upwardly against Vthe feed wheel 15 by a roller 76 over which itpasses. Roller 76 is Xed on a short shaft or pin`77 at the rear yend of a lever 78 pivotally mounted be-L tween its ends at 103 on the head and actuated by spring; 85 to oress Vroller 76 against the belt' 73. It is evident that with this construction, the'stem of a leaf of to bacco, when entered under thev roller 16 down the inclined 'groove 89 made in the upper .side of the vhead k7 in front of. the

roller, will, when they belt 73 comes to such position that the end of the stein mayl enter a notch 73a, be drawn under the roller 16 and thence under the feed wheel 15, the stem passing under the slot between theplatcs 697and while the sides of the'leafsprea'd over the carrying belts A and B. yThis has the effect to tension or stretch the 'leaf at each side of the stein as it passesunder the wheels 16 and 15and renders the same particularly easy to cut at such tensionediparts when brought into contact with a rotary cutting' knife, as will now be described.

Tlieknives 74 and 75 are of circular forni and are located below the plates 7 Candi-39, respectively on opposite sides of theslot between the plates. a plane slightly below'the; other knife 75 and is oppositely beveled Vas shown. Said knives are fixed at'the upper ends of vertical shafts 94 and 93 which are rotatablyV mounted at ther rear ends ofY brackets 67 pivotally mounted on the underside of the head 7 in spaced apart relation, one at each side of the -slot between platesk 69 and 70. Each bracket is pivotally mounted between its ends on a vertical .shaft 82, which passes upwardly through one end ofl across bar 68 disposed below brackets and extends across the space between the saine, and

each vertical shaft y82passes throughv its" Vbracket and connects 'with the head 7. A

coiled spring 79k under compression.V is disposed between the front ends vof the brackets 67, the'tendency being toV bring the rear ends of the'brackets together7 which tend- One knife 7 4t is located in encyy is controlled-by an adjusting screw 81 threaded'npwardly vthrough bar 63 and provided with a. beveled head to contact with associated beveled lugs projecting from the brackets 67 back of their pivotal vmounts as '5 shown in Fig. 4,. this adjusting the brackets and the knives 7e, and 75 to any, desired position with respect to'eachvother. A locking washer 801s used with adjusting screw'81 to keep it ina-ny position to which it may be adjusted.

Directly in front `of the knives 74 and are located two fingers 72, pivotally mounted on the head 7 under the plates 69 and 70, on the pins y'102. {One of these 5 fingers is located'vat each side of the slot, its forwardend being beveled on its-under side andits rear end on its upper side, and. drawn normally across the slot rby .springs 9.5 andV 96. The ystein vof the'leail of tobacco passes under the inneredges` of saidngers72, theleaf at points adjacent the stempassing with the belts l yand 5 over said lingers and the adjacent head 7 towhich they are attached` this aiding in stretching the .leaf at the stern for easy' cutting all of thev tobaccorof anyy value ,from the stem, it being apparent that'the oppositely beveled circular knives sever the stem` from the leaf,

the stem being delivered into an outlet tube eoy 91 at the back of the head 7 being guided therein from the knives under the part 92 of the head 7, as vshown iniig. 3.

An electric motor 65v is located adjacent the left hand side of the support, having' conwliich the neetion with ashaft 66 through a universal v joint connection shown at 62, and (Sei Fig. Shaft 66' is rotatably mounted on and-under a swinging arm 614located horizontally substantially .in abn-ement with the motor shaft,v and the shaft 66 atV its Vfree end carries :i spiral gear 30 adapted to mesh f with 'a similar gear 31'on`. the lower end of the vertical shaft 32.
