Letters Patent No. 108,355, dated October 18, 1870.

IMPROVEMENT IN TOBACCOfCASING MACHINES.

The Schedule referred to in these Letters Patent and making part of the same I, EDWARD HOLBROOK, Jr., of the city ofLou isville, county of Jefferson and State of Kentucky, have invented a certain new and useful Improvement in Tobacco-casing Machines, of which the following is a specification.

This invention consists in providing a small troughshaped case, secured to a suitable frameA or plat-forni, on one end of which case rests the stands or housing of a pair of small rolls, made somewhat similar to a clothes-wringer, the .outer surface of which is covered with a thick coating of India rubber; the upper journal-boxes of the rolls are made to slide in the stand, in order to adjust the rolls, which is done by a set-screw in the top.

The rolls are provided. with an apron or table, both on the receiving and discharge side, but the one on the receiving side is provided with angos at the sides, in order to keep the tobacco in place, and is also used as a table on which to lay the leaf-tobacco preparatory to being sprinkled with the 'desired liquid preparation, which is supplied from a ,small trough immediately above the entrance to the rolls.

The lower edge of this trough is made nearly sharp,

4with a long slot-hole in the under edge through which the liquid passes down into anothertrough-shaped boni, attached to an adjustable slide, on the under side of the iirst trough.

The under side of this last-named trough is perforated with holes, in order to distribute the liquid more evenly over the surface, and to regulate the quantity required on the leaves before entering the rolls, theliquid for the purpose being supplied from thev large trough below, by means ol" elevator-cups att-ached t0 an endless chain, operated by power applied to suitable pulleys above and below.

The one at the lowcrend is made to work in bearings made similar to a elevis, with a screw on one end, which passes through the end of the trough,

-with a thumb-nut on the out-side, in order to take up the slack of the chain.

This chain and the rolls are driven by power applied by means of a series of suitable pulleys and spur-gearing, a portion of which is attaehedto a small wooden iame erected on the platlbrni at the side of the large box, while. the others aro attached to the rolls on the box.

The object of my invention is to provide an economical and expeditious means of saturating leaf tobacco with any desired liquid preparation, preparatory to Aa further process Vin its manufacture;

and also to distribute the liquid more evenly over. the

whole surface, in order that it may be pressed sufficiently dry for use as it passes through the rolls.

The manner of operatingl this invention is to pre-A pare the desired liquid, and put it in the large trough below, the bottom of which descends to the elevators, by which the liquid is carried up and deposited in a small trough over the rolls, the leaf tobacco being placed on the apron or table, ready to receive the liquid as it falls gradually on the leaves as they pass through the rolls.

The top of the liquid-trough is made to answer as a table, on which to prepare the tobacco.

Having thus fully described my invention, a more complete understanding of which may be had by reference to the drawing* Figure l is a vperspective view of the back part of the machine, showing the gearing by which it is driven.

Figure 2 is a view ofthe front of the machine, with apart of the covering left oif, showing the interior ot' the liquid-box and elevators.

Ris the covering of the liquid-box, which is also used as a table on which to prepare the leaf tobacco.

L and N are the pulleys of the elevator-chain.

I) I? is t-he chain.

M M M are the elevator-cups, by means of which the liquid is raised from the box B, and deposited in the trough K.

Q is a thumb-nut, by which the slack of the clevator-ehain is taken up.

O is the clevis-bearing at the lower end, and is a guide for the chain, secured to the side of the boxframe.

Z is the discharge-table ot' the rolls.
