ing ceramic ware, but it will be'understoody that the drier can be used for drying other materials without departing from the essential features of the invention. a

One object of the invention is to provide a drier with a rotating table upon which the material to be vdried is placed, and a. further object of the invention is to provide meansA for circulating heated air in the drier while the position of the material is being shifted in respect to the currents of heated air.

In the accompanying drawings: u Figure 1, is a Sectional elevation of a drier made in accordance with my invention;

Fig. 2, is a sectional plan view of the drier shown in Fig, 1;

23' Fig. 3, is a sectional elevation of a drier,

having side circulating passages; Fig. 4, is a sectional plan view of Fig. d;

Fig. 5, is a sectional elevation of a modication of the drier shown in Fig. 1;

Fig. 6, is a sectional plan view of Fig. 5; Fig. 7, is'a view of a drier in which the turntable is mounted on a vertical shaft, and ,illustrating an overhead drive;

Fig. 8, is a sectional plan, view of Fig. 7 Fig. 9, is a sectional elevation of a drier in which the material to be dried is mounted on a series df platforms or tables carried by a single vertical shaft; I

Fig. 10, is a sectional plan view of Fig, 9; Fig. 11, is a sectional elevation of a drie-r having a centrally located turntable and a circulating fan at each end, and

Fig. 12, is a plan view of the drier shown in Figrll.

Referring in the first instance to Figs. 1

and 2, 1' is the casing of the drier. -Some distance from one end of the casing is a vertical partition 2 in which is an opening 3. Lolcated in the opening is a circulating fan l l 59 mounted on a -horizontal shaft 5 extending through one end of the casing 1 and having -a belt pulley 6 thereon for a power driven belt. p

'Z' is abase'located within the casing and DRIER.

' the lower edge of the vertical partition conforms to one side of the turntable so as to cause the air to circulate over the turntable and return under the table to the space back of the fan, as shown by the arrows. In the 5 space back of the fan in the present instance are heating pipes 14.- which may be of any form and arranged in any manner desired.

In the-present instance, I provide deflectors. Y

or shutters 15 in front of the fan. These shutters are preferably pivoted so that they can be ladjusted to allow more or less air to circulate and to direct the air as desired.

j At the end of the casing opposite to the fan are doors 16 to allow for the loading of the turntable with material to be dried and to remove the dried material.

It will be seen that as the heated air is circulated, the material being dried is turned, and if more than one article is being dried, the position of the diiferent articles is changed, so that the article or articles are more evenly dried than when they are 18 are two partitions extending forward from the vertical partition 2a, one on each side of the turntable 9a. These partitions preferably extend to the full height of the drier and terminate short of the forward end of the casing to form a circulating passage. The partition 2a in this instance` terminates at the side partitions 18 so as to allow for free circulation of air, as

shown in Fig. 4. 14:a are coils of heating ip'es, and 15a are the deflectors or shutters.

cors 16a are at the front end of the drier. In Figs. 5 and l 6, a drier is shown in which the fan 4l is mounted on a vertical shaft 5b extendingthrough the roof of the drier and driven 1n any suitable manner. A horizontal partition 19 having an opening for the fan is connected to a vertical Apartition 2h extending across the drier and having an opening therein, in which are located the shutters 15?. The heating `pipes 14h are located in the space back of the partition 2b and under. the fan. The turntable 9b is driven in the same manner as the table shown in Fig. 1.

In Figs. 7 and 8, the turntable 9 is mounted on a vertical shaft 8c having its lower bearing in a step 7 c and extending through an upper bearing 20 in the roof of the drier. On this shaft 8c is a wo-rm wheel 10c driven by a worm on a shaft 12e. In this instance two circulating fans lc are shown, and there are twovertical partitions 2c separated by a channel 21 formed by two short longitudinal partitions 22. The heating pipes are located back of the fans and the channel. Thecirculation of heated air is clearly shown by the arrows in Fig. 8.

In Figs. 9 and 10, I have shown a series of turntables or platforms 9d lon a vertical shaft 8d driven from above. The shaft 8d is mounted in bearings similar to the shaft in Fig. 7, and the lower turntable preferably rides on rollers 23 located under the table near the outer edge. In this instance, the air is circulated in arhorizontal path as in Fig. 4:.

In Figs. 11 and l2,- the turntable 9e is located `at the center of the drier casing le, and there is a circulating fan 4 at each end of the drier, the fans being located between two partitions 22. rIhe air circulates in va horizontal path over the center of the turntable, returning', over each side of the turntable, as shown by arrows, Fig. l2. There are doors at each side of the casing opposite the turntable.

In each one of the machines described above, the material is rotated as itis subj ected to heated airin circulation, thus thoroughly and evenly drying the material.

I claim:

l. 'Ihe combination in a drier, of a casing enclosing a drying chamber; a turntable located within the chamber, the table supporting the material to be dried; means for circulating air across the table and in shaft and worm gearing through which the l table is turned by the shaft; a fan at one end of the drier for circulating. air in the chamber; and means for heating the air.

4. The combination in a drier, of a casing enclosing a drying chamber; a base; a vertical shaft mounted on the base; 'a turntable carried by the shaft; a driving shaft geared to the vertical shaft; a partition having a fan opening therein; a circulating fan located in said opening; a shaft on which the fan is mounted; Aand means for heating the air in circulation.

5. The combination inv a drier, of a casing enclosing a drying chamber;'a vertical partition located near the rear end of the casing and having a fan opening therein; a circulating fan insaid opening; heating means in the space between Ithe partition and the back wall of the casing; a turn- `table located in the space between the partition and the front of the casing; and a door in the front of the casing.

6. The combination in a drier, ofla casing enclosing a drying chamber; a vertical partition in said chamber; a turntable on one side of the partition; heating means on the other side thereof; a horizontal partition extending from the lower end of the vertical partition to the turntable; and means for circulating air in said chamber.

7. The combination in a drier, of a casing enclosing a drying chamber; avertical partition in said chamber; a turntable in the chamber; means for circulating air around the partition and over the turntable; and shutters for controlling the flow of air, said shutters being located between the partition and the turntable.
