TOIALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be itiknovm that I, EDWIN F. BAILEY, of Holderness, in the coun'ty'of Grafton, and State of New Hump. shir`e,have invented a new and useful Card-Board Dri'er; .and I do hereby declare the same to' be fully described in the following specification, and represented in the accompanying drawings, of which#- Figure lis afront elevation,

Figlire 2 an end view,

VFigure 3 'a transverse section, and.

Figure 4 a longitudinal section of it. Y

Figur-c 5 'is a vertical `section of it, taken through one of the air-distributing channels, and its steamheating pipes, and so as to exhibit the framing for supporting the eard-board carriers. l l

V'.lhe purpose of the invention is to dry sheets of pasteboard, 'or card-board, or other articles of like character, after being made.

vIn the drawings, A is a eloseboir or building, formed as represented, and provided with a ventilator, B; such ventilator'bei'ng placed at the middle part ofthe top of the said box or building, and furnished witha valve, C, to be opened or closed as occasion may require, by means of a rope, D, or other device. Each side of the box A is open, and provided witlr sliding-doors E E for the purpose of closing such sidefasgoccasion may require. Within the said box there are arranged two frames, FF, and with a space, G, between them, such space being at the middle of the box, and continuing vertically up to the upper part H thereof.. Each of tho frames F F is to-'be constructed as a frame is usually made for holding a series ofdrawers, that is to say, with parallel guides for supporting the drawers,- and enabling them to be moved into 'and drawn out of the frame. The frames F, however, have the guides arranged at inclinations with the horizon, as shown at a a a, in iig.' 3,4 and they are for supporting a series of card-board carriers G', one of which isshown in top view in Figure 6, itgbeing a rectangular frame, having wires or threadsstretched across it. They, that is, the carriers, with cardboards on them, are to be run into the frames F, or the divisional parts thereof, and are separated by such, and so arranged that there maybe a space both above and below each of the said carriers, for the hot air to circulate through. Between each ofthe said frames F and the door openingnext thereto, and in or within the floor of the box or chamber A, is a channel, H, for receiving air, the top ofthe said channel being foraminous, or providedfwithnumerous openings, to enable the air, when forced into the channel, to 'cscapc therefrom against one or'more pipesI arranged immediately over the air-channel; such pipe or pipes, when in use, being connected with a steam-generator or other proper means of heating such pipe or pipes, by the introduction of steam, hot water, or hot air therein. I t is intended that the air-channel or channels H shall be connected withan airblast apparatus by which air may he forced into it or them., Such air, on being discharged against the heating pipe or pipes, will become heated by such, and from thence will be caused to flow upwardand through thc frames F F, and-in colntact with the wet sheets of said-board arranged within such. The vapor created by the evaporation of the moisture of the card-boards will rise and be discharged withv the air through the ventilator.

A card-board drier of the above-mentioned kind will be found `of great advantage to paper-makers, or those engaged in making pasteboard.

1 I make no claim to the fruit-drying apparatus, as described in the United States Patent No. 28,775, in

which several series of inclined drying-frames are so arranged directly over one another and an air-heating chamber that the hot air, after having passed between the frames of one series, is caused to pass between those of the next one. With my improved arrangement of the frames, each set has'a hot-air space or chamber in front ofit and over the apparatus forheating the air, and suchair passes between all the frames at once, each current of aircarrying olf its moisture wit-hout going a second time between any two frames. The air charged with the moisture escapes into a common vertical space, G. Thus it will be seenl that my arrangement is much more favorable for drying the card-boards than that described in such patent.

I claim the arrangement of the forjaminous air-channel or channels, supporting-frame or frames, provided withinclined guides, and the box` A, constructed and provided with doors, and for the purpose.specified.

the heating pipe or pipes, the carrier with each other and the airchambers at either end, and a ventilator and valve thereto, substantially as'described I EDWIN F. BAILEY.
