HARRISON W. HOLLEY, OF LYNCHBURG, VIRGINIA, ASSIGNOR OF ONE- FOURTH OF HIS RIGHT TO EDWARD T. POLLARD, OF SAME PLACE.

MACHINE FOR ROLLING AND CUTTING TOBACCO.

SPECIFICATION forming part of Letters Patent No. 225,833, dated March 23, 1880.

Application filed August 20, 1879.

To all whom iii-may concern Be it known that I, HARRISON W. HOLLEY, of Lynchburg, in the county of Campbell and State of Virginia, have invented a new and Improved Machine for Rolling and Cutting Tobacco, of which the following is a specification.

Figure l is a plan of the machine. Fig. 2 is a longitudinal sectional elevation on line 00 00, Fig. 1. Fig. 3 is a side elevation of the same. Fig. 4 is an enlarged sectional elevation of rollers with lubricating-box and scraper between them. Fig. 5 represents a plan of grooved rollers used in forming twist-tobacco. Fig. 6 represents a plan of rollers with circular knives for cutting plugs to any desired widths.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide further improvements on a machine for rolling and cutting tobacco for which I received Letters Patent N 0. 209,808, dated November, 12, 1878.

In the drawings, A represents the supporting-frame, which is constructed of side plates that are firmly braced by transverse pieces, and arranged to form at one end a guiding box or trough for a feed-belt, B, and for the rest of their length a trough for containing the pressure and cutter rollers and the lubrieating-boxes and scrapers.

The feed-belt, which is preferably an elastic metallic band, is tightly stretched over the rollers G D, of which D forms, in connection wilth a top roller, D, the first set of pressurero ls.

The leaf-tobacco is prepared in the ordinary manner and placed on the feed-belt. Put in motion by the pulley or wheel E, the belt conveys the tobacco through between the rollers D and D, by which it is lightly pressed and shaped. These rollers then pass it over the tops of one of the lower combined lubricatingboxes and scrapers, F, and between a second set of rollers, G and G, that are of greater diameter than the first rollers, and consequently press the tobacco more closely together. Pushed or passed in like manner between the still larger rollers H H, the tobacco is subjectedto greater pressure, and thereby reduced to the required thickness. The axles of these rollersare all set in the same horizontal plane, but each succeeding pairis of greater diameter than the preceding one. Were they all of the same diameter, the tobacco would pass through the first set, if the speed of all were equal, faster than the second set could take it up. From between the last set of compressing-rollers the pressed tobacco passes over one of the lubricating-boxes and between the rollers I and K, the former of which is provided with a simple blade, a, extending across its entire length, while the latter is preferably a solid roller of sole-leather or some other elastic material. As these rollers turn the knife cuts the pressed tobacco into the desired lengths.

The set-screws b b serve to adjust the relative position of the lower to the upper rollers, so that any desired pressure may be applied to the tobacco, and the screw 0 serves to adjust the roller 0 horizontally for the purpose of regulating the tension of the belt.

The guides L, fixed against the inner sides of the trough, extend between each set of rollers and serve to determine the width of the plug of rolled tobacco. These guides are interchangeable with others of different thicknesses.

The boxes F reach across the trough, and are divided into two parts or reservoirs by centralvertical diaphragms, d, and they are provided with inclined scrapers f and covers g, that also serve as scrapers. Proper packing of cotton-waste or other material is put in each box, and oil is provided to one reservoir and water to the other for the purpose of softening the gum, &c., that adheres to the rollers from the tobacco, and the boxes are so arranged that a scraper is brought against a roller between the oil and water feeds, and so that the oil-packing will wipe off the water and prevent it touching the tobacco. By means of the scrapers and oil and water the rollers are kept perfectly clean. Oil and water and scrapers may be also in like manner supplied to the belt, as herein shown.

The feed-belt and pressiug rollers are revolved in the same direction by suitabletransmitting-gearing, (shown in side elevation in Fig. 3 of the drawings,) and the cutting-rolls are moved in the same direction, the power for these purposes being applied through the crank or pulley E.

In lieu of the smooth rollers usedin the machine for making plug-tobacco, the grooved rollers O, as shown in Fig. 5, are used for making twist-tobacco, or rather to press or shape the tobacco in a round form that the twist may be afterward given to it; and in the same machine the rollers P, provided with circular knives 19, (shown in Fig. 6,) are sometimes used for cutting pressed tobacco to any desired widths. The knife 0 can be made to cut the plugs of tobacco to any desired length by increasing or diminishing the size of the pinions or gears that work the roller I that carries the knife.
