DRYlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 506,917, dated October 17, 1893.

Application led October 11, 1892. Serial No. 448,499. (No'model.)

.To all whom it may concern.-

Beit known that we, JOSEPH J. DE KINDER, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and AXEL S. VOGT, a subject of the King of Sweden and Norway, and a resident of Altoona, county of Blair, State of Pennsylvania, have invented a new and useful Improvement in Drying-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

Our invention has for its object the production of a machine in which various materials may be treated and thoroughly dried, and it is especially adapted for the drying of what' are known as brewers grains; and our invention consists incertain arrangements and combination of mechanism whereby the heat is evenly distributed to the material to be dried and is prevented from passing into that portion of the receptacle unoccupied by the material to be dried.

In the drawings-Figure l is a longitudinal section partially in elevation of our apparatus. Fig. 2 is a section on line 1 2, Fig. l. Fig. 3 is a section of one of the pipes. Fig. 4 is a detached perspective view of a modied form of port closing device. Fig. 5 is a section on the line 3-4, Fig. 4. Fig. 6 is a view similar to Fig. 2 of a modified form of apparatus.

A is the receptacle for the material to be dried,fwhich is preferably a perforated cylinder having doors lor movable portions, A', for the insertion and removal of the material, and surrounded by a solid casing B having corresponding doors, B B2' C are the steam or other heat-inlet pipes. Through the cylinder A passes the conduit or ipe D, which is secured to said cylinder A and opens into the pipe C. This pipe D rests in bearings a. upon the support or stands a', and it is adapted to revolve, and may be revolved by means of the wheel E secured to said pipe D beyond the cylinder A (Fig. l). Within the cylinder A, opening into said conduit D and projecting therefrom at an angle to the axis of rotation of said pipe D, are the perforated pipes F. These pipes are made in two sections, f, f (see Fig. 3), connected together by the joints f2, said joints having the inwardly projecting iiange f3, forming what may be called a port between the two sections of pipe F.

G is an angle-iron frame, forming a valve, the extent of which is greater than the width of the port. One end of this angle frame or valve is pivoted to one side of the flangefs, and the projecting portion of the angle frame or valve is adapted to rest on lthe flangefs.

H is a rod connected to one arm of the angle frame, and connected at its other end to an arm f5 projecting from the angle-iron frame or valve G. Upon this rod is the weighted sphere or ball I, through which ball the rod H passes loosely. In place of the ball or sphere j being suspended on the rod H, it`may be placed between the rod H and the an gle-frame (see Figs. 4 and 5). As may readily be seen, as the pipes F revolve, the ball I will slide upon the rod (or between the rod and the frame), tilting the frame, and according to the position of the ball, open or close the port. The closing of the port occurs when the pipe is standing inclined upward in the position projecting upward from the conduit or pipe D, and as the pipe moves downward from the vertical position it opens, the closed position being that where a portion of pipe F projects beyond the material to be dried.

Instead of using a single central conduit,a series of conduits or pipes may be usedfas shown in Fig. 6.

Having now fully described our invention, what we claim, and desire to protect by Letters Patent, is

l. In a drying machine the combination with a receptacle to receive the material to be dried, of a heat conduit extending through said receptacle and adapted to rotate with said receptacle, pipes opening into and projecting from said conduit at an angle to the yaxis of rotation of said conduit, said pipes being provided internallywith a port, an angle framed valve adapted to cover said port, said angle framed valve being hinged, and a weight upon said frame adapted to move upon said frame when said pipe is revolved.

2. In a drying vmachine the combination 3. In aV drying machine the combination- With a receptacle to receive the material to be dried, of a heat conduit extending through said receptacle and adapted to rotate with said'receptacle, pipes opening into and-projecting from said conduit atan angle to the axis of rotation-of said conduit, said pipe being formed in two parts, a joint uniting said parts, said joint having an internal flange which forms a port within said pipes, an angle framed valve adapted to cover said port, said angle framed valve being pivoted and a weight upon said valveand adapted to move z 5 upon the frame when said pipe is revolved.

4. In a drying machine the combination with a receptacle to receive the material to be dried, of a heat conduit extending through said receptacle and adapted to rotate with 3o said receptacle, pipes opening into and projecting from said conduit at an angle to the axis of rotation of said conduit, said pipes being formed in two parts,ajoint which unites said parts, said joint having an internal flange 35 which forms a port in said pipes, an angle 'framed valve Aadapted to cover said port, said angle framed valve being hinged, a rod or bar .secured to said frame, and a weight through kwhich said rod or bar passes and upon which 4o Ysaid weight is adapted to slide.

In testimony of which invention We have hereunto set our hands.
