APPARATUS FOR DRYING TILE.

SPECIFICATION forming part of Letters Patent No. 751,852, dated February 9, 1904.

Application filed April 28, 1903. Serial No. 154,648. (No model.)

To all whom it may concern,.-

Be it known that I, DAVTD FORD HENRY, Jr. a citizen of the United States, residing at Port Murry, in the county of vWarren and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Drying Fireprooiing-T ile, &c. of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to the drying of clay and other wares preparatory to burning, and has particular reference to improved apparatus for eecting a rapid, economic, and thorough drying of freproofing-tile.

r1`he invention consists in the novel structural features and arrangement of parts hereinafter fully described and claimed, and illustrated by the accompanying drawings, where- Figure 1 is avertical longitudinal sectional View of apparatus constructed in accordance with my invention. Fig. 2 is a top plan View of the same, partly in section. Fig. 3 is a front elevation. Fig. 4 is a sectional elevation of the discharging end of the apparatus, taken on line 4 4 of Fig. 2. Fig. 5 is a plan view of the air-inlet mechanism shown in Fig. 4. Figs. 6 and 7 are detail views of the pallet hangers or carriers. Fig. 8 is a similarrview of the pallet.

Referring to the drawings, 2 designates the drying chamber or tunnel having ware-inlet opening 3 at the upper end of front end wall 4, and rising from said end is stack 5, while at the bottom of the chamber and near its discharge end is air-inlet 6. Extending from the ioor nearly to the crown of the chamber are baile walls or mantels 7, and alternating therewith are similar walls or mantels 8, depending from the chamber-crown nearly to the iioor. thus formed which communicate alternately at the top and bottom, thus providing a circuitous or indirect passage for the ware, also for the air.

At the outlet end of the drier is compartment 9', and beneath the latter and open thereto at 10 is chamber or passage 11, which eX- tends to the front of the drier, where it is open in front of end wall 4.

A succession of compartments is` Extending across the drier adjacent its top and bottom are shafts 12, carrying sprocketwheels 13, and passing over and around the sprockets are the endless conveyer-chains 14, which return from the discharge to the inlet end of the apparatus through chamber 11, sprockets being provided therefor at the ends of said chamber, with horizontal guideways or slides 16 between the sprockets to sustain the chains and prevent sagging.

17 represents hangers pivoted in pairs at 18 to the inner sides of chains 14, with inwardlydisposed lifts 19, hinged at 20 to the lower ends thereof and adapted to turn upward thereon, the arrangement being such as to prevent the lifts from dropping below horil zontal position.

At the front or inlet end of the drier and in the path of the conveyer is table or support 21, adapted to receive the ware-carrying pallets 22 and sustain them in position between chains 14, to be engaged at the ends and carried upward and forward by lifts 19 and hangers 18. The pallets are formed, preferably, of perforated sheet or plate metal strengthened by turning the edges thereof, as shown at 22.

l/Vith the hangers loosely pivoted between the chains'the pallets, if properly loaded, will remain in upright position throughout the entire course, passing upward and downward around the sprocket shafts and wheels and around mantels 7 and 8 until they finally emerge into the upper portion of compart- -ment 9. In this compartment the chains and hangers descend on opposite sides of car or truck 23 and automatically deposit thereon the pallets of dried tile, the chains and hangers descending therefrom through openings 10 into return-passage 11. The pallets may be Adeposited on the car in courses three or more partment 9, intercepted by turn-table 26, the 100 empty cars may enter and the loaded cars emerge from either the end or side of the structure, as may be most convenient in passing to and from the kilns.

For actuating the conveyer a shaft 27 is supported on the exterior of the drier on brackets 28 and operatively connected to upper shafts l2 by worm-gearing 29.

Stack 5 is arranged at the ware-inlet end of the drier, and air-inlet 6 adjacent the waredischarging end, so that the conveyer and aircurrents move in reverse directions, thereby effecting a rapid and thorough drying of the ware. The dried tile approaching the discharge end of theA drier are enveloped by the dry inilowing air, and as the latter iiows forward toward stack 5 and becomes laden with moisture absorbed from the tile it comes in contact only with the greener tile in preliminary stages of drying.

Air may be supplied to inlet 6 by any suitable means, that here shown being a blower 30, arranged to draw its supply from a conduit 3l, leading to kilns (not shown) in which the ware is burned, thus utilizing heat from burned or burning kilns which is usually wasted. When heated air from kilns is not available, the blower may draw its supply from the atmosphere through inlet 32, the double-acting valve or damper 33 serving to simultaneously open inlet 82 and to close the kiln-passage, and vice versa. Before entering the blower the air may be drawn through a nest of steam coils or pipes 34E, and thus heated, the same being designed more especially fil use where hot air from kilns is not availa e.

It will be understood that the number of mantels or baffle-walls may be increased or diminished as required and that the distance between adjacent hangers or pallet-carriers may be varied. Manifestly the apparatus may be variously embodied as regards structural details without departing from the spirit and scope of the invention.

I claim as my inventionl. In drying apparatus, a drying-chamber, a succession of/open vertical partitions forming a circuitous conveyer course therein, and a conveyer movable through said course.

2. In drying apparatus, a drying-chamber, a succession of :open vertical partitions therein forming a circuitous conveyer course, a
