To aZZ 1071 0122 it may concern: show an interior construction. Fig. 3 shows Be it known that l, ALvAN A. SIMONDS, a the shaft employed in one form of my interior citizen of the United States, residing at Day support. 55

One form of conthe operator full access thereto. struction for accomplishing these results is In Fig. 1 I have shown in section two differshown in the accompanying drawings, and dcent constructions for supporting a thin web of 5 scribed in this specification, and the invention paper and directing the air against the same. is fully pointed out in the claims. One of the constructions consists of a small In the drawings, Figure 1 is a view of a roller, D, journaled in the side of the box or portion of a drier constructed in accordance tube, This roller is of less diameter than the with my invention, the drying tube or box and distance from the path of the paper web to 50 the parts connected therewith being shown in the lower side of the box. This admits of a section. Fig. 2 is a plan View of the same passage of air beneath the same; but as the with a portion of the top broken away to air in such case would be directed away from 'tion.

tube beneath the paper web may be directed against it, I place over the shaft D a guide, (2,

the paper, I place a guide, d,.inclining from the bottom upward toward the paper to direct the air against the same. In the other construction shown I employ a shaft, D, which is provided at intervals with narrow fixed collars D. The diameter of these collars is equal to the distancefrom the path of the paper web to the lower'side of the box, and, the paper web coming in contact with the upper part of these collars, is supported in its proper posi- In order that the air admitted to the consisting of asheet of rigid material provided with slots or openings through which the collars I) may project. The portion of this guide between the slots is supported just above the shaft D, and its edges arebent downward and attached to the bottom of the tube or box A. Instead of making D of a sheet of thin material, it may be made of a solid material with openings for the shaft D and recesses for the collars D The operation of the construction shown and described it is thought will be clearly understood from the foregoing description. In introducing the thin web of paper the pipe 0 is turned, giving the operator access to the interior of the drier at that end. The web being introduced through the narrow slot, the operator returns the pipe 0 to its place, and, opening one of the doors a, carries the web through the box to the rolls on the other side. The web, coming in contact with the collars D of shaft D, is supported in proper position during its traverse through the box or drier, while the air admitted to the under side of the paper web will have a sufficient space to pass beneath the paper and will be directed against the same. It will be no ticed that the guide (1, when made of sheet material, is made to extend to both sides of the shaft D merely for convenience and to give it rigidity. Such guide might be divided in the center along the line of the shaft and the part farthest from the air-inlets dispensed with, the inclined portion rising from the bottom of the box to the top of the shaft between the shaft and the air-inlets being the only part necessary to effect the result desired.

It will be noticed that in the description of the operation herein the paper web is spoken of as moving from the end provided with a narrow slot toward the other 'end. I do not desire to limit myself to such a movement of the paper, but the paper, if desired, may be passed through the drier in a reversed direction.

I have shown anddescribed a drier consisting of a narrow box or tube having air-inlets at the top and bottom at one end and an opening the full size of the tube at the other end; but this construction is not claimed herein, as it forms the subject'matter of my application, No. 202,119, now pending. I

\Vhat I claim, and desire to secure by Let- 1. The combination,with a box or tube having an opening at each end for the passage of the paper web therethrough, of an air-inlet in the top near one end of said box, and doors or lets at top and bottom near one end, of a support for the paper web, consisting of a roller having a space. beneath the same and a guide inclining from the bottom of the tube upward toward the paper, substantially as described.

3. The combination, with the tube or box having openings at each end forthe passage of a paper web therethrough, air-inlets at top and bottom near one end of said box, a sup-.

porting-roll for the-paper web, consisting of a shaft provided with rigid collars and an airguide on the side nearest the air-inlets inclining from the bottom of the box to the topof the shaft between the collars, substantially as described.

4. The combination, with the tube or box having openings at each end for the passage of a paper web therethrough, of a support for the web within the box,consisting of shaft D, provided with collars D and the slotted guide (1, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
