Patented June 29, 1954 APPARATUS-AND METHOD FOR CONDITIONING TOBACCO Rush D. Touton, Wynnewood, Pa., assignor to Wurton Machine Company, Philadelphia, Pa., a corporation of Pennsylvania Application: October'l'l, 1952,'Serial No; 315,236

8 Claims.

This invention relates to apparatus-andmethod for conditioning tobacco and more particularly to apparatus for wetting the butts of tobacco leaves, tiedin hands, preliminarily to the conditioning of the tobacco leaves asa whole.

It has long been customary in the preparation of tobacco for processing, as, for example, the

manufacture of cigars, to subject it to treatment for adjustment of its moisture content, more particularly, as we are concerned here, by the addition of moisture.

The" addition of moisture to butt and leaf portions of dry tobacco with a view of adjusting moisture content thereof to that desired and with that uniformity throughout the butt and leaf portions which will condition it for processing has long presented a problem, more particularly because the butts of tobacco leaves absorb moisture much more slowly than do the leaf portions; and. this characteristic is enhanced when the leaves are tied into hands by a tie encircling and constricting the butts. Hence a treatment which will effectively condition the tips and median portions of tobacco leaves will not be effective to simultaneously effectively condition the butt portions of the leaves.

Heretofore highly efficient procedures and apparatus have been developed for the conditioning of the leaf portions of tobacco leaves, but the butt portions have required preliminary treatment, as hand dipping or the provision of spray means for wetting the butts, prior to treatment of the leaf portions.

According to this invention, apparatus is provided for effecting dipping of the butt portions of hands of tobacco leaves, while manipulating the butt portions relative to the leaf portions, from a description of the operation of which the method according to this invention will be made apparent.

The apparatus according to this invention may be used alone or in combination with apparatus for conditioning the leaf portions of hands of tobacco, such, for example, as is illustrated and described in United States patent to Rush D. Touton, No. 2,379,118, dated June 26, 1945.

Having now indicated in a general way the nature and purpose of this invention, I will proc'e'ed to a detailed description of the construction and operation of a preferred embodiment thereof, with reference to the accompanying drawing in which:

Figure 1 is a plan view of the form of apparatus embodying the invention.

Figure 2 is a vertical section taken online- 2-2 in Figure 1.

Referring to the several figures, 11 indicates a frame serving to support, in bearings 2, 2", a pair of spaced shafts 3, 3' which carry rollers 4", 4" over which travels an endless belt 5.

An auxiliary frame 6 mounted on the frame I 2, between the rollers 4, 4'" serves to support, in bearings l, 1', a pair of spaced shafts 8, 8' which carry rollers 9, 9' over which travels an: endless belt I'll of the width of belt 5: and the lower reach of which rides on theupper reach of the belt 5;

At one side of the belt 5 and adjacent to the edge thereof is a tank H adapted to-besupplied with Water through a supply pipe 12 equipped with a. valve (not shown) controlled by a float I-3 to maintain a controllable level of water in the tank. The water supplied through pipe I2 may be heated or cooled by any constant means.

Supported from a longitudinal member of frame 6, by slot and pin connection for adjustability and spaced from the edges of belts 5 and NJ is a guide member It which extends from above the plane of the belts forwardly and downwardlyinto tank Ii and has its lower end portion [8' turned to-extend upwardly at an angle. A second guide member is, supported from frame 6, bya slot and pin connection for adjustability, extends from above the plane of the belts 5 and Ill rearwardly and downwardly into-tank I I and has its lower end portion [9' bowed downwardly beneath the upturned end portion [8 of the member [8. The member I 9 is spaced further from the edges of belts 5 and. it than is member IS.

The shaft 3 supported fromthe frame carries. a sprocket it with which. is engaged an endless chain l5 which with an endless chain 16.

engaged with a sprocket [.1 serves as a conveyor to convey hands of tobacco received from the belt- 5 for treatment tocondition it, for example, with apparatus and by procedure fully illustrated and described in the aforementioned United States Patent No. 2,379,118, or by other apparatus and/or procedure as may be desired.

It will, of course, be understood that the belt 5 is driven by a suitable prime mover, as an electric motor, connected in any suitable manner, as, for example, by chain and sprocket to the shaft 3. Likewise the chain 15 may be driven from the prime mover by the belt 5 in passing over roller 4'.

While the apparatus described above will comprise a complete apparatus, it will desirably and usually, for maximum production with economy of space, be associated with a duplicate arrangement in opposite spaced relation with a single tank I I as illustrated in Figure 1.

In the operation of the apparatus illustrated, it will be understood that the belts 5 and lb and the chains l5 and IE will be travelling in the direction indicated by arrows, Figures 1 and 2.

Toproceed, hands 'of tobacco 2f! will be successively placed, by operators, on the belts 5, ahead of the belts Ill, in opposite extension, with their butt portions extending beyond adjacent edges of the belts; and preferably with their leaf portions somewhat overlapped or shingl'edall-as clearly showrrin- Figure 1L.v

In the travel of the belts the leaf portions of the hands will be carried under and be engaged by the belts l0. Then the butt portions of the hands 20 engage the guide members l8 which depress or bend the butt portions, relative to the leaf portions which are held by belts [0, down below the plane of the leaf portion into the water in tank I I. As the butt portions reach the upturned end portions l8 of guides [8, they are engaged by the downwardly bowed end portions IQ of guide members l9 and thereby bent upwardly above the plane of the leaf portion; and then released to assume a normal extension beyond the edges of the belts.

Finally the hands 20 are delivered by belts 5 into the nip of chains 15 and [6, which serve to convey the hands for further treatment as indicated above.

Variously the butts portions of different tobaccos and the different conditions will require more or less water, heated or cooled water, defiection downward into the tank II and upward. The requisite condition, i. e., amount of water in tank ll, temperature of the water and deflection, will be obtained by adjustment of float I3, guides l8 and I9 and supply of water to tank I I at requisite temperature.

It will now be appreciated that the apparatus according to this invention serves at onceto effect a clipping of the butts portions of hands of tobacco and a manipulation of the butts by downward and upward bending thereof with respect to the leaf portions, which manipulation serves to distribute the water taken up in the dipping toward the leaf portions and facilitate its absorption by the butts of the leaves comprising the hands; and some time a manipulation or flexing of the leaf portions is effected.

It will be understood that various modifications of the apparatus and procedure above described in detail may be made without departing from this invention as defined in the appended claims.
