APPARATUS FOR DRYING or BRICK.

Specification of Letters Patent.

Application filerl February 14., 1916. Serial No. 78,230.

To allwlwm it may concern.-

Be it known that 1, JOHN 0. Boss, citizen offthe United States, residing at Elkhart, Indiana, have invented certain new and useful Improvements in Apparatus for Drying of Brick, of which the following is a specification.

My present invention relates to the drying of bricks and other compressed or shaped plastic products, and has for its object to dry them by direct and uniform application of the air. current in the simplest and most economical manner as regards both apparatus employed and labor incident thereto, and the invention comprises the novel method of operation and features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

An. apparatus embodying my invention is shown in the accompanving drawings, in which Figure l is a transverse sectional view of the drier.

Fig. 2 is a sectional elevation.

Fig. 3 is a view of a modification.

According to my present construction, I provide, preferably, a plurality of chambers 1 formed by parallel walls, the lower part of which walls may be formed of reinforced concrete, as indicated at 2, and the upper of brick, as indicated at 3, though it will be obvious that the complete wall may be built of any suitable heat resisting material. A shoulder or ledge 2 is formed at a suitable point on each wall, such, for example, as at the junction of the lower portion 2 and upper portion 3, and such shoulders may conveniently be formed by widening out the upper portion of the lower parts 2 of the walls, as illustrated by the drawings. Beneath the floor of the chambers 1 are located hot air supply ducts 4, which communicate by the branch passages or feeders 4 with the chambers, said chambers being opened at both ends and provided with tracks 1 upon which trucks 5 may be run into the chambers from either end.

These trucks are of the elevating and lowering type and designed to support at their upper ends the perforate pallets 6, upon which the bricks are loosely piled with spaces therebetween, as clearlv illustrated in the drawings. A truck so loaded with bricks to be dried may be run into a chamber from one end and thereafter the lowering mechanism operated to lower the pallets until their ends rest on the shoulders 2 then the truck may be drawn out of the chamber and receive a pallet of fresh bricks, which may be carried into the chamber and lowered in proximity to the preceding load. The pallets may be of any suitable construction, having open spaces to permit the passage ofair, a convenient form being that shown in the drawings.

The walls 3 are parallel 'so that the chamber formed between them is completelyopen and unobstructed :at the top and the pallets of such width that their edges approach very closely to the inner faces of the side walls, so that the bricks piled thereon will lie so closely to such inner faces of the sidewalls as to preclude any appreciable quantity of air passing around the outside faces of the load of bricks. In other words, only suflicient clearance is left to allow the pile of bricks to be passed into and out of the chamber and only enough air passed up around the outside faces of the pile to efiect a drying action, the bulk of the air supplied to the lower part of the chamber by the ducts 4 being caused to pass directly through the openings in the pallets and up through the passages between the loosely piled bricks, whence it escapes at the top directly to the atmosphere. lVhile I have described the ducts as located directly beneath the track, it is obvious that they might be arranged at one side and communicate with the air chambers through the lower portions of the walls 2.

Instead of using elevating trucks, as shown in Figs. 1 and 2, I may, if desired, use trucks having permanent platforms, as distinguished from removable pallets, such platforms being indicated at 6 and being provided with openings for the passage of air. In this form the side ledges or projections for supporting the pallets would not be needed and the walls could be parallel from the base.

\Vith driers constructed as above described, the air is caused to pass directly up through the brick, escaping directly to the atmosphere, and this without the cost of installing and manipulating movable parts, and keeping these parts in proper adjustment and repair.

The channels are provided with doors at their end capable of being closed after the bricks are in place to prevent escape of the drying air out through the ends of the channels and these channels are also provided with roofs, as indicated in the drawings, to.

keep rain and snow from forming upon the brick, but it Will be understood that these roofs are elevated suiiiciently and supported by openwork upon. one or both sides so as to permit the free escape to the atmosphere of the air carrying the moisture from the brick.

While I have described and illustrated my invention as more especially designed for drying brick, it will be' obvious that 'it may be utilized for drying other articles, among which may be mentioned any articles of clay or like material and also briquets, such as are made from coal dust combined -with other materials.

Having thus described my invention what I claim is:

1. An apparatus for drying brick and other products, comprising a track and side walls forming an open-topped channel, trucks adapted to run on said track within said channel, and having perforated supports for the brick with the sides of said supports in close proximity to the channel Wall, and air ducts for supplying heated air to said track channels below the truck loaded thereon, to come in. close proximity to the channel-walls, and air ducts for supplying heated air to said track channels .beneath said loaded pallets, substantially as described.

In testimony whereof, I aflix' my signature in presence of a Witness.

' JOHN C. BOSS.
