6 Claims.

This invention relates in general to the treatment of tobacco and more particularly has reference to construction of tobacco-carrying sticks and of a wall of a tobacco-treating device, which supports the tobacco-carrying sticks.

Several constructions have been developed for supporting tobacco in treating apparatus, but I have found that the structures heretofore employed do not serve adequately in treating ap- 10 ir or other gas is circul tobacco-carrying sticks be removably positioned in the treating apparatus. The supporting means heretofore used were found to be disadvantageous when employed in the treating devices in which air is circulated, in that the supports caused eddy currents to be set up in the air flow. which affected the treatment of the leaves of tobacco nearest-the obstructions.

The primary object of this invention is to devise structure for supporting tobacco in treating apparatus which is free from the disadvantageous features present in the structures heretofore employed.

Another object of this invention is to devise a tobacco-carrying stick having novel means for securing the tobacco thereto.

Yet another object of this invention is to devise a mechanism for effectively securing tobacco to a carrying stick without injuring the tobacco.

Still another object of this invention is to devise a wall construction adapted to detachably receive tobacco-carrying sticks.'

A still further object of the invention is to devise a treating chamber having a wall construction adapted to support tobacco-carrying sticks in cantilever fashion.

With these and other objects in view, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

The present wall of a treating chamber with a plurality of slots, into which are positioned reinforcing strips. The strips may be of such width that they extend through the wall of the chamber. A supporting strip ispositioned between the extending portions of said strips and is affixed to the upper reinforcing strip. The lower reinforcing strip and the 56 supporting strip serve as bearing surfaces to sup-` invention contemplates forming a Harris, Stamford,

port a tobacco-carrying stick in cantilever fashion. In order to prevent side movement of the tobacco-carrying stick, a plurality of blocks are spaced apart between the reinforcing strips in the plane of the wall a distance sufficient to receive the tobacco-carrying sticks therebetween.

The sticks employed may be either square, triangular, or of other geometrical form in cross section, and are provided with means for securing the tobacco to the sticks, which may then be positioned in the sockets provided in the supporting wall.

In order to make my invention more clearly understood, I have shown` in the accompanying drawing means for carrying the same into practical effect, without limiting the improvements in their useful applications to the particular constructions which, for the purpose of explanation, have been made the subject of illustration. This invention, of course, is adaptable for use in connection with supporting articles other than hands of tobacco.

Figure 8 is a detailed view of one form of wall construction.

In Figures 1 and 2 I have shown a chamber 1 190 l for treating tobacco, that is, a chamber in which tobacco is suspended and through which a current of air is circulated to condition the tobacco. The chamber 1 is a portion of a treating apparatus 2, which includes a conditioning chamber 3 105 and the products chamber l. The vconditioning chamber extends about the chamber l and is separated therefrom by partitions 4 and 5, provided with slots 6 and '1, respectively, and by side walls 8. The lower conditioning chamber may, if de- 2 1,982,990 sired, contain a water tank 9, and the upper complete.asherein deseribed,theouterandinner lconditioning tankmay contain a tank 10. through surfaces may be covered with sheet metal 24 or which the extendedwalis of slots 6 pasa.

When 'a hand of tobacco is placed on the stick, the spreading apart of the leaves will be gradual, so as to prevent any breakage thereof. It will be appreciated that the triangular form of the tobacco-carrying stick may be supported in the wall structure hereinbefore described, or, if found desirable, the triangular sticks may be provided with an end portion which is square in cross section, so that it may be fitted into the sockets provided in the wall structure 12.

It will be appreciated from the foregoing description that the invention provides a wall construction which may be easily and economically constructed. and which effectively serves to retain article-carrying sticks in desired positions.

The construction herein described is particuiarly advantageous for use in industries in which it is desirable to maintain material-carrying sticks or supports in a definite relationship, because of the close-fitting socket construction afforded by the present invention. Also the guide construction permits the sticks to be easily and quickly inserted into the close-fitting sockets. The particular stick constructions are of peculiar utility under various conditions of practicaloperation.

While the invention has been described in connection with a tobacco-treating apparatus, I wish v it to be clearly understood that it may be employed in apparatus for treating various other materials, or in any type of apparatus in which articles are to be suspended.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and-variations may be made therein by those skilled in the art without departing from the spirit of the invention or exceeding the scope of l.
