DRYING-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 506,916, dated October 17, 1893.

Application filed October All, 1892. Serial No. 448,498. (No model.)

To all whom it may concern:

Be it 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 1o 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 0f 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 ourinvention consists in certain arrangements and combination of mechanism whereby the heat is evenly distributed to the material to be dried, and is prevented frompassing into that portion of the receptacle unoccupied by the material to be dried.

In the drawings-Figure l is alongitudinal section partially in elevation of our apparatus. Fig. 2is a cross-section of drying cylinder. Fig. 3 is a cross-section of modified form of drying cylinder. Fig. 4 is Vis a section of one of the pipes.

A is the receptacle for the material to be dried, which is preferably a perforated cylinder having door or removable portion A B B2 being the doors in the outer cylinder for the insertion of the material surrounded by a 3 5 solid casing B. l

C are the steam or other heat inlet pipes, which are secured to the receptacle A and rest in bearings a supportedupon stands a. The pipes C are adapted to be revolved, and may be revolved by means of the wheelD secured to said pipe C through the cylinder A. Secured to the heads of said cylinder so as to revolve with it is a series of pipes E, which pipes open in the iiared out portion of pipes C. Projecting from the pipes E, preferably radially, are a number of perforated pipes e. These pipes e are shown in section in Fig. 4.

In the upper portion of each of these pipes is a frame Work or guide-Way G, which is se- 5o cured together and to the pipe. The lower portions of this guide-way approach each Vother so as toleave but a slight space g.

H is a ball or sphere the cross section of which at its greatest diameter is greater than the space g, so that said ball is adapted to, and will, fill said space. The ball H is placed in said guide-way, and when the pipe assumes a vertical position, projecting above the conduit pipe to which it is connected, the ball H will roll down the guide Way and fill the space g, preventing anyl steam or hot air reaching the upper end of the pipe, and as the pipe passes gradually downward in the rotation of the receptacle A, the ball leaves said orifice and runs along the guide Way, opening said 6= orifice and allowing the steam or hot air to pass through the entire length of the pipe. lVhen the pipe is ascending the ball kwill move along the guide-way toward the orifice g and will close the same when the pipe is above its 7o corresponding conduit'pipe, which is the position of the pipe when it is partially above the material to be dried.

The operation is as follows: The material tobe dried is placed in the receptacle A and the same rotated, steam or hot air being admitted as before described, and as the pipes rise above their conduits, as before described, the ballsmove down the ways and close the orifice or space g, and as they pass downward, move away from said orifice, opening the orifice or space g, so that automatically the upper portion of the pipe is closed when it is in the upper portion of the receptacle and again automatically opened as it passes into 8 5 the lower portion of the cylinder. The position of these Ways may be varied so as to cut off more or less of the pipe when the oriiice is closed, according to the quantity of material in the receptacle.

If desired, in place of a seriesof steam conduits E, one central conduit E may be used, as shown in Fig. 3, from which the pipes e project, as shown in said gure. The steam may be admitted at one end of the cylinder only if desired.

Having now fully described our invention, whatwe claim, and desire to protectby Letters Patent, is

l. In a drying machine, in combination Ioo with a receptacle adapted to rotate, pipes adapted to receive and distribute a heating,r medium and at an angie to the axis ot' rotation of said receptacle and a spherical valve and seat in each pipe.

2. In a drying machine, the combination with a receptacle adapted to rotate, of a conduit passing through said receptacle and adapted to a heating medium and rotate with said receptacle distributing pipes opening into said conduit and projecting from said conduit at an angie to the axis of rotation, and a spherical valve and seat in each distributing pipe.

3. In a drying machine, in combination JOSEPH J. DE KINDER. AXEL s. voer.
