.. Slwcilcation forming part of Letters Patent l\'o. 42,4 @5, dated kApril 26, 1564.

To all whom' t may concern. y Be itknown that I, Envflnn HoLBnooK,

Jr., of Louisville, inthe coiinty of `Jefferson andState of Kentucky, have invented a new and Improved Mode of Forming Tobacco` Sheets, and I do'hereby declare the following to be a full and exact description of the same,

reference being had to the accompanying draw` ings, making part of this speeiiication, in

ywhich# y A. Figure l is a plan of a machine illustrating myinventionl.,l Fig. 2 is a side elevation there# of. Fig. 3 is avertical longitudinal section in the line x fr, Fig.` I. Fig. 4L isfan end eleva-` tion. Fig. isa` Similar letters of reference indicate corresponding partsin. the several iigures. i

l The object 'ofthis invention is to `press i stemmed leaf-tobacco into sheetswith rapidity, economy, and cleanliness, preparatory-to its being divided into slabs andlumps.

To this end theinvention consists, first, in laying the l`leaves. in flat form between movable boards dr plates, and by the aid of a suitable;

table, of one or more adjustable stops or gages to arrest the motion of the `feed-boards when passed to a proper position within the press. In order that. others skilled in the art to l which my invention yappertains may be enabled to fully understand and use the same, I

will proceed to describe its construction and operation. y f

In the drawings, A A m'ayrepresent a feeding-table mounted upon supports A2, and inclosed by the side pieces, A3 A3. Thistable, as shown in Fig. 2, is formed in two sections, which are indicated, respectively, bythe letters A A', one oi saidV sections, A, being elevated somewhat above the other, in order that two persons :may work with convenience and expedition at the table, and thus have a ertical transverse section in l constant supply of tobacco in readiness to be submitted to the action of the press.

.B B represent nat boards, between which the tobacco is arranged inV proper quantity to form asheetrbefore being passed into the press, said boards being moistened or lubricated to prevent the gumm y matter in the tobacco from accumulating thereon, and permit the tobacco to readily slide tl'ierefrom after having been pressed in sheets.

A portion, A4, of the side pieces, A?, is provided with "hinges a, whereby it is :adapted to be turned down to allow the workman to feed .the `rotate@ ont@ `the; table A with facility.: l l

The table or Vtables A A are provided with casters o', toadapt the boards B E', with the Q tobacco between them, to be more readily slid` v into the press.

G represents the upper wall, C C the adjustable side walls, and C3 the bottom, ofa press, which is inclosed by a suitable retainc1302.

, D D represent screws which pass through` r the walls UIQ C of the press and are employed in connection `with a compound crank, D', by

meansof which the screws may be turned in y such manner 'as to move the walls C in oppoy site directions, thus increasing the space between the latter and allowing the boards B B',

with their charge of tobacco, to be passed into the press without interception, which done the crank D may be operated reversely, so as to cause the walls C, to approach each other until they come in contact with the carrying-boards.

lTo facilitatethe feeding ofthe tobacco to the press, I employ one or more adjustable gages, E', which may be of semicircular or othershape, and may be provided with a hand-lever and a spring-catch to place and retain them in their prominent or working position. These gages, when turned to lthe position shown in Figs.` 1 and 3, serve to arrest the feed-boards B B at the proper .point as they are passed Y into the 4press withtobacco between them.` 7

'Ihe correct adjustment of the'sheets within the press' is thus effected without difficulty or i delay, and when the pressing has been com-v pleted the said gages,.by turning them fora ward or backward, as the case may be, are lowered to thelevel ofthe table, so as to per# mit the vfeed-boards to pass freely over them "in forwarding the pressed sheets to the cutf ting mechanism.

The bottom C3 yof thepress is formed with a f projection, 0*, which enters a receiver, C5, to l' Awhich latter' water or other liquid may be supplied through a pipe, c, and aperture c. This bottom C3 constitutes a ram or a compressing 'medium similar to a piston.- Liquid being inl troduced into the receiver kO5, the ramG3 ascends with great force and compresses into ,l `-compact sheets the tobacco which may be.

placed betweenthe samev and the' upperk wall, y j The'tobaoco having been thoroughlycompressed, the liquid in the receiver Cf" isallowed v' topassout at a suitable valve, when the ram j C falls to its lower'position. .This operation- ,jof "elevating and `lowering the rain C3' may be 'ply .the tobacco from the feeding-table. @I have thus described aform vof press which I have applied yto my invention with goodefl feet; but `having `made this' the subject of ay separate application, I do notdesireY to be understood as limiting myself tothe use of this yparticu1arpress-'` j l .l

"The' drawings also represent an improved slabbing apparatus, which, having been made the` subject of a separate application, requires no'specic descriptionhere.ky

. I do not desire to beunderst'ood as limiting myself tothe use of atable withtwo sections only. Y.'Ilieobject of this part of my invention performed as rapidly as theworkmen can supis to provide a succession of different levels o'n which the fcedboards may be placed for the reception of the leaves, so that when the series of feeds or layers are completed theylmay,

withl convenience, be slipped successively one upon another and all passed into the press tol gether. It will be manifest that for this lpurposea table of three,.four, or more sections "or levels maybe employed to receive-as many pairs lof feed-boards.

Having 'thus described my invention, the l following' is what I claim as new thereinand desire to secure `by Letters Patentz 1. Forming tobacco sheets from theleaves by laying the leaves inliiat form between movable boards or tes'and pressing, substantially as set l'forti'.

2. Afeeding-table 'formed inftwo orjvlmo're sections, A', arranged latk'different heights, substantially as andl for th'e'purpose explained.

` 3.,'lhe wheels or rollers a, in combination v with thertableA A', adapted for use, substan- .d l -tially as and for the purposes described;` 4., In combination `with the aforesaid feeding-table, one ormore adjustable gages, E2,-

employed, in the'vmann'er described, to regulate-the introduction of the tobaccointo the press.l f
