IMPROVEMENT IN GRAlN -ELEVATORS.

Specification forming part of Letters Patent Ho. 138,994, dated May 20, 1873; reissue No. 6,127 dated. January 12, 1875.; application filed J anuary-B, 1875.

DIVISION A.

To all whom it may concern: I

. Be it known that we, HENRY I. GnA-sn, PHI- LANDER'F. CHASE, and EDWIN D. GHAsE, of the city of Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Elevating, Conyeying, Storing, and Shipping Grain; and we do hereby declare that the following is a full,

clear, and exact description thereof, that will enable others skilled in the artjto-which it appertains to make and use the same, reference being had to the-accompanying drawings, and to the letters of reference marked thereon, which form-apart of this specification,

Figure 1 is afront elevation of the grainhouse, the left half of the same being shown in section Fig. 2, a. sectional elevation, asseen with proper grain houses or bins ext-ending out from them, the latter being about sixteen feet square and'about the same height, ar-

ranged inrows running outfrom the elevatorbuildings, and built thus low and directly upon the ground to obviate the enormous pressure of accumulated grain in housesof many storice, and more freedom from damage'by fire; second, in providing an'opeu passage between each double row of grain-bins extending from the ground upward, and in which' open-passage the conveyors have an independent foundation, and. extend from the elevator to the rear of i the line of bins to securesaid conveyers from derangement from settling of any part of the bins; third, in the employment of parallel lines of conveyors for doing the work of moving the grain, the elevators being merely used to raise it above the level of the top of the bins.

The following is the-construction of the elevator-houses and their annexed line'of bins, the number of each not being material to the principle involved. The numbers here used merely indicate proportion between the elevator-buildings and the bins or store-houses. (See Fig. 4.) Six elevator-buildin gs built -in a line, each about forty feet high by about twenty feet square, each having a grain-sink beneath. it about twelve feet deep, with an ordinary elevator about forty feet high, operated by an upright shaft and line of shafting in the top and bottom. of the houses. These elevatorbuildings are shown at Fig. 4. in the drawing, but the elevator proper A is shown attached to the outside of one of the bins, and rising from a grain-sink, merely to illustrate the connection of thebins with the same. There are no grain-sinksunder the bins. Each elevator house has a grain-house .or'long line of bins, O D, attached to it, consisting oftwo rows of bins, D D, extendingont at right angles with an open passage, Gr, between each double row of bins. in which. passage the upper .andlower line of conveyors are built, so asto secure for them an independent foundation, as before mentioned.

The elevator-building has a wagon-way on-thc first floor through the house, for the convenience of receiving grain from wagons. The lower conveyor, E, is built upon the ground, and the upper conveyer is supported from the ground or from the lower-conveyor by posts k k. A building for grain on this plan, covering one. acre, consists of six .double lines of bins, O D, about sixteen feet square, and about two hundred feet inlength, holds about six. hundredthousand bushels in secure storage, at a cost of about ten cents per bushel, whereas on the old plan of, high elevators the storage would cost about thirty-five cents per bushel. ThebinsD D are each about sixteen feet square, built of' studding two by eight, and fourteen inches apart, covered with one-inch boards, the floor sloping toward the conveyor E The bins are tied by stock-boardse e e, nai .d to the stndding, one set horizontally across-each way at the top of each bin, and another set in a similar manner is placed in the middle of each bin. .'Spouts f f discharge grain from the sloping floors of the latter into the conveyor E The upp'er conveyors, E, also discharge grain byspouts laterally into the bins on either side.

A platform, 9 g, from which to superininto the lateral bins D D.

tend this conveyer, issupported partly by the posts In It and partly by the sides of the bins. A similar platform is placed over the lower conveyor. Each conveyor consists of a continuous line of screws, made in sections, united by gudgcons. Each section is a continuous spiraliron scrcwor flight about eighteen inches in diameter, winding along a central shaft, E about eight inches in diameter, and about twelve or more feet in length, coupled to each adjoining section by gudgeons, and supported in journal-boxes suspended from the top of the conveyer-trough.

The operation of this system of handling and storing grain is as follows: When corn or grain is to be stored it is shoveled into a hopp'ered sink, B, under the elevator, from whence it is raised by elevating to the top of the house,

where it is spouted into a weigh-hopper, and thence into the conveyer E and carried along the Arehimedean screw at the rate of fifty or more bushels per minute; whence it passes through the traps in the trough hr conveyor 111 shipping produce, it passesfrom each bill by spout f into the lower conveyer, E and is brought back to the elevator, which discharges it into the weigh-hoppers, and is spouted thence into the cars on the adjoining track.

When the operator desires to change from cats to corn or other grain, he first inserts a bunch of broom-corn into trough of conveyer, holding the projecting portion of the broom while the screw carries it along, and sweeping itself clean to a single grain.

The advantages of this system are, first, thatit is unnecessary to. elevate grain any higher than from forty to forty-five feet, and will not strain. the buildings when stored in bins but;

sixteen feet high, and is vastly more secure from damage by fire. Such storage is obtained at about one-fourth of the ordinary cost, as the plan ,above described holds about six hundred thousand bushels, and covers one acre,

at a cost of about fifty thousand dollars, while i an ordinary elevator holding the same amount 'cost's about two hundred thousand dollars;

steam are fully su flicien t, whereas to elevate the same quantity requires fifty pounds of steam; third, the bins, built sixteen feet only in height, hold grain at a much less risk of damage by fire, by reason of the small amount of material used in their construction, so much so that grain will not be very materially damagedby a fire, but in such case can be all saved in a slightly-damaged condition.

Having thus fully described our invention, what we claim therein as new, and desire to secure by Letters Patent, is-.-

l. The system described of receiving, con veying, storing, and shipping grain in rows of bins O D, of one-story in height, arranged-on either side of an upper and lower line of convevers, E E one line'for receiving and distributing grain, the other for discharging the same, constructed to operate substantially as and for the purposes set forth. 4

2. The system described of a-combination of elevator-houses, Gr Gr,- in one line, of not more than two stories in height, from each of which runs back at a right angle a double line of store-bins, having an upper and lower lineof conveyers E E built on independent foundations, substantially as. and for the purposes set forth.

3. The construction and combination of the binsG D, walls d d, stays e e e, floor z, spouts ff, passages g gyconveyers E. E", posts k k, spout b, platforms h, and elevator A, substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands.
