EJNITED STATES PATENT OFFIC HENRY CUTLER, OF NORTH VVILBRAHAM, MASSACHUSETTS.

- GRAIN- DRIER.

SPECIFICATION forming part of Letters Patent No. 269,644, dated December 26, 1882.

Application filed June 28, 1882. (Nomoileb) To alt whom it may concern:

Be it-known thatI, HENRY CUTLER, ot'North \Vilbraham, in the county of-Ha'mpden and State of Massachusetts, have invented a new and Improved Grain -Drier, of which the fol lowing is a full, clear, and exact description.

My improvements relate to grain driers of the class shown in Letters Patent granted to the September 20, 1881, and numbered 247,318,

in which the grain is passed through a revolving cylinder heated by steam-pipes.

The object of my present invention is to provide for the construction of driers with large capacity,in which the temperature can be raised to a high point; also, to provide for expansion and contraction without any injury to the machine or the liability of breaking joints and consequent leaking.

To these ends my invention consists in the novel features of construction hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal section of my im-- proved steam-drier. Fig. 2 is a transverse section on line 00 m of Fig. 1, showing the steamhead. Fig. 3 is a transverse section on line 1 o 3/ of Fig. 1. Fig.4 is a longitudinal section ofa. plug for the admission of steam and escape of water through the hollow journal of the drier; and Fig. 5, a transverse section of the .plug on an enlarged scale on line a a, Fig. 4.

A is the cylinder, constructed of wood, and provided with steam head B at its lower end and head 0 at its upper end. The steam-head B is formed double or hollow, with a central partition, to, and radial partition plates b, by

0 which four chambers are formed at each side of thepartition-plate a, of which the chambers at the outside (marked 0) are in the form of sectors separated by the spaces d. The inside chambers between partition a and back plate, d, are marked 0'.

The partition-plate a is formed with numerous holes that receive the ends of pipes j,

which pipes extend lengthwise of the cylinder.

The inner or back plate, at, of the steam-head is apertured to correspond with the partitionplate a, but the holes are of larger size, to receive the pipes 9 that receive the pipes f. The

opposite ends of these pipes g are received and supported by an apertured disk, 0, and these ends are closed. It will be seen that by this construction the smaller pipes fconnect with the outer chambers, 0, while the larger pipesg are open to the chambers c at the inner side of the partition-plate a and back plate, 61.

The head B is formed with a hollowjournal, 6a 2', by which the lower end of the cylinder is supported in the bearingsj. In this hollowjour nal is titted the steam-plug D, that is formed to allow the inlet of steam into the cylinder and the outletofwatcrtherefrom,asnextdescribed. 65

The plug D is formed with a central passage,

k, for steam, and a side passage, Z, for water. At its outer end the plug has a side aperture,

k, for connection with the steam-pipe, so that the steam entering the passage it enters the chambers c of the steam-head, and at the end of the water-passage l is an opening, Z, for connection to a steam-trap. The inner end of this passagel opens out upon the surface of the steam-plug so as to communicate with the inclined passages m m that are formed in the hot low journal 13, and through the steam-head B tov the inner chambers, c, with which the pipes g communicate. By this construction the steam entering by passage is to the steam-head passes into the pipesf, and thereturn steam and water of condensation are carried by the pipesg to the inner chambers, c, of the steam-head, and from thence pass through the passages to to the passage l of the steam-plug. The passage 8 l communicates with each passage m once during a rotation of the cylinder.

The several chambers c at the inside of the partition-plate a, and between it and back plate, d, are connected together at their inner 9o ends, and pockets are thereby formed similar to those represented at n, Fig. 3, which serve to collect the water of condensation, and by the passages in, communicating with these pockets, the water is carried off. 9 5

The steam -plug is provided with annular packing 0 p to prevent the escape of steam. The outer packing is compressed by a gland fi, applied around the outer end of the plug, and

the inner packing, 0, is held in place bya bail, I00

0, connected to a rod, 19, that passes through the center of the plug to the outside, where the rod is provided with a nut for tightening the packing.

The steam-head B and upper head, 0, are conneeted together by stringers q of wood, which are bolted to them, the stringers being thereby held securely by a material that is not affected by heat. Iron segmentsj pass from one stringer to the next, and these segments serve to support the outer wooden casing as attached around the segments by hoops to, thereby giving the cylindrical form and required strength to the casin g.

The shaft of the cylinder is bolted to the inner side of the steam-head B, and passes through the upper head, 0, where it is formed as a journal for support of the cylinder. The shaft is fitted interiorly of the cylinder with partitions s, which extend the whole length of the cylinder, so that they serve to divide the interior into four separate sections, each section containing a cluster of the tubingfg and a ventilating-aperture, t, Fig. 1, so that each section constitutes a separate drier, and the grain being divided equally by the partitions the weight is balanced, so that less power is required to operate the drier.

The separate compartments are fed with grain by means of the buckets a, which are fastened to the outside of the cylinder next to the disk U,and in the rotation of the cylinder these buckets pass successively through a trough a under the cylinder to which the grain is supplied.

The apertures in the cylinder A beneath the buckets are fitted with inclined plates as, by which the grain is moved forward. These plates also cover the apertures, so that the grain cannot pass out of the cylinder when the buckets are at the under side of said cylinder.

Any suitable outlet for the grain from the cylinder after it is dried may be provided, as I do not seek to make any improvement in that part of a drier.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The cylinder having the hollow steamhead B, with the apertured plates 0. d, partition-plates Z), four chambers on each side of plate a, the pipesfg, and the disk 0, as shown and described.

2. The cylinder-head B, having chambers c, hollow jonrnalt, with inclined passages m, and hearings in combination with a plug, D, hav' ing the central steam-passage 7r, lateral waterpassage l, and openings 7; I, as shown and described.

3. The combination, with the head B, having passages hr, back plate, d, and the plate a, of the chambers 0, connected at their inner ends to form pockets at, and communicating with said passages, as shown and described.

4 The combination, with the packing, of the gland 2 around the outer end of the plug 1), the bail 0, and the rod 12, passing through the center of plug, as described.

5. In grain -driers, the combination, with the steam-head B, having the hollow journal 4' and passages m, of the steam-plug I), provided with the separate passages 70 l for steam and water, substantially as shown and described.

6. In grain-driers, the steam-head B, constructed with the separate steam and water chambers, and the hollow journal t' in one piece, substantially as shown and described.

7. In grain-driers, the steam-plug D, having the passages k Z, and provided witlrthe packings 0 p, in combination with the hollow journal 1 substantially as described.

8. In grain-driers, the combination of the buckets a, plates or, and trough a, substantially as described, for operation as set forth.

9. In grain-d riers, the feed-buckets u,t'or su pplying the cylinder, in combination with the cylinderA and trough v, substantiallyas shown and described.
