COOLING-CHANNEL FOR ORDERING TOBACCO.

SPECIFICATION forming part of Letters Patent No. 520,441, dated May 29, 1894.

Application filed March 81, 1893.

To ctZZ whom it may concern.-

Be it known that I, SAMUEL P. MAYO, of Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Cooling-Ohann els for Ordering Tobacco; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in cooling channels for ordering tobacco, the 0b- JGClI being to provide simple and inexpensive means for effectually moistening air for the process of ordering tobacco.

With this end in view my invention cons sts in certain novel features of constructron and combinations of parts, which will be hereinafter described and pointed out in the claim.

In the accompanying drawings, Figure 1 is a view in side elevation the front of the apparatus being broken away to show the interior construction, and Fig. 2 is a similar view, with the side removed.

A represents a conduit or channel preferably square in cross section, and provided with an air inlet a and outlet 1) both of which are preferably smaller in diameter than the main or body portion of the conduit or channel. The shape of this channel is immaterial as it could be cylindrical or any other -shape desired.

In the enlarged or body portion of the channel are placed a series of sheets of metal designed when in operation to be covered by a film of water. These sheets can be plain flat sheets as shown at c, and if desired can be covered on one or both sides with a cloth (1 which absorbs the water as it falls on the plate and by capillary attraction and gravity of the water becomes saturated from one end to the other. Instead of using plain sheets of metal as described it might be desirable to employ sheets corrugated as shown at e. These corrugations retard the progress of the Water downward and consequently expose it for a greater length of time to the action of the steam to be hereinafter referred to. At

at g a single sheet of gauze, either of which Serial No. 468,464. (No model.)

answers the purpose of the sheets 0 d and e heretofore described. At It I have shown a plain sheet similar to c perforated as at 2'.

These perforations retard the flow of the thin film of water and expose the water for a longer period to the action of the steam. These sheets whether they be plain, corrugated, wire gauze or cloth are preferably supported at their lower ends by rods j which latter hold them in position equi -distant apart and prevent them from swinging. These plates extend across from one side to the other of the conduit or channel and nearly the entire length and separated a suitable distance apart to permit air to freely pass between them to receive moisture.

The pipe or channel may lie in various po sitions from nearly horizontal to vertical but preferably inclines at about an angle of fortyfive degrees. Perforated pipes Z extend across the upper ends of the plates and discharge a constant supply of water thereto, the water being supplied to all the pipes Z through main 0 and the latter is furnished with a suitable valve 0' by which the supply is regulated.

A steam pipe S is located in the bottom of the conduit or pipe, and is provided throughout its length with a series of discharge nozzles or openings 8, the latter being so located relative to the sheets that a jet of steam is discharged into each space between the sheets and between the end sheets and the sides of the conduits. The current of air may be blown from the bottom or drawn from the top, or it may be drawn from the bottom or blown from the top. In either of the latter two instances the steam pipe S should be at the top instead of at the bottom as shown.

The operation of the device is simple and is as follows:The current of air forced or drawn into the conduit or channel is divided and passes between the plates or sheets. The air passing over and in contact with the water with which the plates are covered, absorbs moisture and the steam which has been discharged into the spaces between the plates or sheets and which is carried on by the current of air, becomes cool and condensed by conpipes whereby passages are left between them,

and steam pipe entering the lower end of the channel or conduit and provided with discharge jets at points opposite or at the lower end of the spaces between the sheets of material, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

SAMUEL P. MAYO.
