CAPSU LE=DRYI NG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 433,991, dated August 12, 1890. Application filed June 24, 1889. Serial No. 315,33Q. (No model.)

To all whom it may concern;

Be it known that I, THEODORE C. MERZ, a citizen of the United States, residing at Detroit, county of iVayne, State of Michigan, have invented a certain new and useful Improvement in Capsule-Drying Apparatus;

and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Myinvention has for its object the production of an apparatus for drying capsules in a simple and rapid manner; and it consists of a combination of devices and appliances, hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of my apparatus. Fig. 2 is an end elevation of the dryingframe removed from the drying-chamber. Fig. 3 is an elevation of the drying-room, showing the ends of the frame. Fig. 4 shows a portion of the frame with the capsule-plate placed thereon.

I11 carrying out myinvention, A represents a suitable room or inclosure in which warm air may be confined, and B represents any suitable stove or other source of heat-supply whereby the room may be properly heated.

0 represents a series of angle-irons extending from the partition a of the room through the latter and beyond for a distance. These angle-irons are supported at one end by the walls of the room and at the other end by. the bands D D. These bands are supported and held in position by the rods d, the whole forming a light and strong truss or frame-work. The angle-irons are so placed, as shown in Fig. 2, that a series of racks are formed, on

which may be placed in radial positions the,

plates bearing the capsules, as shown at E in Figs. 3 and 4. At the outer ends of these radial racks may be placed small drop-doors F, so as to retain as much heat in the room as possible. To place the capsule-plates on the racks, the operator raises the door F and shoves a plate in, as shown in Fig. 3 and by the dotted lines in Fig. 1.

this along by the insertion of another plate,

and so on until the rack is filled, and each rack may be successively filled in this way.

G is a fan adapted to revolve within the He then pushes circle formed by the radial racks and to circulate the air around the racks. This fan may be revolved in any suitable manner-as,

for instance, by the belt 9 passing overa suit- I able pulley.

The operation is obvious. The radial racks having been filled with the capsule-plates, the fan is revolved and the hot air of the room circulated around the capsules, thus rapidly drying and hardening them. The plates can then be pushed along to the outer end of the racks, and the fan still revolving the cool air outside the room is circulated around the capsules. By making the delivery end of the racks slightly lower than the other end, as shown, the sliding of the plates from one end to the other is facilitated.

What I claim is- 1. An apparatus for drying capsules, consisting of a drying-chamber, an open framework provided with racks composed of an inner annular series of longitudinal angle-irons, an outer annular series of longitudinal angleirons and the annular bands D D',and radial rods d, connecting and supporting said angleirons, the capsule-mold plates E, supported by and adapted to slide in a right line along said angle-irons, and a rotary fan located within the circle formed by the inner series of angle irons, substantially as described.

2. An apparatus for drying capsules, consisting of a drying-chamber, aninclined framework arranged partly within and. partly outside the drying-chamber and comprising a series of racks composed of inner and outer concentric series of longitudinal angle-irons G, inner and outer annular bands D D, and radial rods d, the capsule-mold plates E,havingtheir inner and outer edges respectively engaging the inner and outerseries of angleirons and adapted to slide thereon in a right line, and a rotary fan located within the circle formed by the inner series of angle-ironsand arranged both within and outside the dryingchamber, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
