MACHINE FOR STRIPPING AND BOOKING TOBACCO.

SPECIFICATION forming part of Letters Patent No. $346,028 dated July 20, 1886.

Application filed April 14,1885. Serial No. 162,180.

To all whom it may concern:

Be it known that I, Josnrn DE LA Man, a citizen of the United States, residing at Poughkcepsie, in the county of Dutchess and State of New York, have invented a new and useful Machine for Stripping and Booking Tobacco, of which the following is a specification.

My invention relates to the production of a machine for manipulating tobacco-leaves for cigar manufacturing purposes, ordinarily called stripping and booking, which has heretofore been and is still largely done by hand.

The following is a complete description of my machine, its mode of construction and operation, as it is fully shown and illustrated in the accompanying drawings.

I have a frame an d table so constructed that by a simple lever motion I can change the plane or surface of the table from ahorizontal to an inclined position, which I do to make the machine work easier. The sliding frame, Fig. 6, that holds the most essential parts of my machine, moves to and fro on the table. The table F is in a horizontal position when the operator feeds the leaf, and causes the sliding frame to reccdc from him by pressing his foot on the. treadle J, which, by levers G G and straps L L, is connected to the front edge of the sliding frame. The rollers B B are rotated by cords d on each side of the table, which are fastened to each end of the table and pass once around the ends of the large rollers in grooves prepared for them, and their companion rollers are rotated by fllClJlOl1-bZtl1dS b,impinging against those rotated by the cords above described, partially by friction on the cleats. To bring the frame back to the operator, the end of the table next the operator is dropped by pulling back the handle of the adjusting-brackets E and the foot taken from the treadle, when the movable frame descends by gravity to the operator. The bed of the table F has a slot, on, in the middle, in which runs a slide attached to the shaft (Z, on which the larger rollers are journaled and revolved. This slot serves to guide the central stem of the tobacco-leaf after it is cut out by the cutters, and the stem passes through the slot and falls on the floor, while the sides of the leaves are deposited on the table each side of the slot.

The object of having a table, instead of a drum, is to better book the leaves and keep them in position, whichcan be more satisfactorily done upon a standing stationary level place than upon a drum or revolving surface. I therefore construct a frame, K, of iron or wood, standing on four legs, having its surface inclined about ten inches to thefront,and on this I place the slotted table, so adjusted that the front of the table can be raised from its supporting-frame and lowered thereto at the pleasure of the operator. On each side of the table,at the edge,I place a cleat about one inch high and an inch and a half wide, which form the track on which the frame-containing rollers move. I construct a movable or slid ing frame of the same width as the table,havin g flanges that extend down a little over the cleats, in which frame are j ournaled the shafts that carry the rollers, the spring, and booking-rollers, and cutters, which comprise the principal operative parts of my invention or machine. side and beneath the table, are journaled on a rod under the front edge of the frame on which the table rests, and are connected by a rod, G, passing from one to the other under the table and mortised in each at about one-third of their length from the front ends. These levers play from a position parallel to the top of the frame nearly down to the floor. Two belts, one on each side of the machine, connect the front edge of the sliding frame with the long ends of these levers, passing over pulleys situated on the outside of the table-frame and over the ends of the long arms of levers G G. I place beneath the frame on which the table rests, and journaled to the front part of the tableframe,near the ground, a treadle, J, reaching to the front of-the machine near the right foot of the operator. To this treadlc is attached a pulley, I, near its middle point, and a cord or strap, 1, passes beneath this pulley attached at one end to the middle point of the rod connecting the levers, and at the other end to the upper part of the rear of the tableframe. This treadle gives motion to the levers that moves the sliding frame on the table. This frame consists oftwo sides of cast-iron or wood, which are held in upright position by the axles of the rollers B B and A A, and two rods at their extremities. I

To cause thelarger rollers to revolve with a regular positive motion, I have a groove cut in the outer ends of the sections of this roller, in which runs a cord,d,that passes once around the roller, and is secured to each end of the table, and lies taut along the above-described cleats F. To revolve the smaller companionrollers in the desired direction, I transmit motion from the larger rollers by means of rubber or friction bands I), or rings on each outer end of the smaller rollers, which impinge upon the eorrespondinglarger roller, and are caused to revolve with the larger rollers, but in the opposite direction. Both the rollers are cut into two parts in the center, over the slot in the table, and their inner ends are provided with steel fiat rings or disks h h and g, having sharp cutting-edges. The rings on the ends of the smaller rollers project about one-fourth of an inch beyond the surface of their rollers, and these edges work within those of the larger rollers, forming cutting-edges or shears with them. The left side or half of the larger roller is provided with a groove and a lug on its shaft, or a lug on the roller and groove in the shaft,which prevents thishalf of the roller from moving sidewise on the shaft. The righthand half of this roller and the shaft are pro- Two levers, G G, one on either IIO vided with screw and threads Kand k,whereby as it revolves it moves on the shaft and expands or contracts the distance between the steel plates on the inner ends of the parts of the roller, so as to conform to the size of the tobacco-leaf.

If the two larger rollers and shaft are taken out of the frame and reversed from right to left, then the leaves may be fed from the opposite end of the machine, and the motion of the frame from the operator will contract the space between the cutters to correspond with the diminishing size of the stem of the leaf. The plates h 7b of the smaller rollers work within those of the larger ones, and are held firmly against them as they revolve by a spiral spring, 2', on the shaft between the parts of the smaller rollers, pressing them apart constantly. This spring is covered by a brass tnbe, 9', to protect itfrom dirt. Both these rollers A B are covered with felt or rubber b b, or other suitable'material, and are kept moist or wet, to prevent the leaves from drying while passing through the machine. To prevent theleavcs from being too much pressed while being booked on the table, I take the weight of the sliding frame on the slats or cleats above mentioned by the larger rollers traveling on said cleats. For the purpose of pressing the tobacco-leaves together, keeping them covered and protected, I place two other rollers, O G, in the sliding frame, one on each side and near the cutting-rollers, journaled in perpendicular slots cin the frame, and enough shorter than the cutting-rollers, so that they will drop down between the cleats on the table, and I hold them down by spiral or other springs 0, applied to the shafts of the rollers within or outside the frame. I also place two spring-rollers, D, in said frame outside of these and above them, whose office is to hold continually taut two aprons, M M, which cover the table and pass around the booking-rollers O 0 near the cutters, and the aprons are fastened at one end to the spring-rollers, and at the other end the aprons are attached to the ends of the table. The apron on the back side of the frame is attached to a rod, N, slipped in eyes a, fastened to the table for convenience of removing or examining the tobacco beneath it. These aprons may be made of muslin or cloth of any kind or other suitable material.

The spring-rollers are so wound and set that they keep the aprons taut continually.

The tobacco can be removed when the frame is at the front of the table by lifting the far end of the apron by its rod out of the eyes and casting it over the frame. The aprons are kept moist continually.

To operate my machine, the lever-braekct, jonrnaled on a rod attached to the frame on which the table rests, is forced back and its arms rise against the bed of the table between the sides of the frame and elevate that end of the table to nearly a horizontal position. Then the sliding frame is set in motion by power applied to the treadle, and as the cuttingrollers begin to move the operator feeds the leaf into the donble shears formed by the cutting-rollers, the stem being between them, and he smooths the leaf as it lies on the large rollers. The stem is thus out out, and the leaves are deposited on the table, each side of the slot, and through the slot the stem falls upon the floor. The one leaf is now booked and lies on the table beneath the front apron. The lever at the left hand of the operator is pulled back and the power taken from the treadle, the front edge of the table is lowered, so that the sliding frame descends by gravity to the operator ready to have another leaf fed. It will be observed that the front bookingroller is so near the large cutting-roller that the apron which travels around it catches and presses the leaf on the table and. one or the other of the aprons constantly covers the leaves outside the cutting-rollers and protects them from the air.

Having thus described my invention, its construction, and operation,whatI claim, and de sire to obtain Letters Patent for, is-- 1. The combination, with the sliding frame and the stripping and booking devices, of the inclined frame and the levers and short arms for elevating the same, as shown and described.

2. In a stripping and booking machine, the slotted table with levers and short arms for elevating the table, in combination with the sliding frame carrying the expanding-rollers and cutters, booking-rollers, spring-rollers, and stem-guide, as shown and described.

8. In a stripping and booking machine, the combination of the slotted table, the sliding frame, the two spring-rollers, two aprons, two booking-rollers, the rollers carrying cutters, the stem guide, the inclined frame, levers for elevating the table, and means for open ating the sliding frame, substantially as shown and described.

4. The rollers A A, provided with disk-eutters upon their inner ends, and having an expanding-spring arranged between them, in

combination with the rollers B B, having cutters upon their inner ends, one of said rollers being provided with screw-threads, and the stationary shaft- (I, having screw-threads which engage those of the roller, as set forth.

5. In a stripping and booking machine, the slotted table, in combination with the sliding frame, the cutting rollers A A and B B, the former being held apart by an expandingspring and the latter separated automatically by the screw-nut K and screw-thread on stationary shaft (Z, and the stem-guide 0, carried by the sliding frame and working in the slot of the table, as shown and described.
