GRAIN-BIN.

SPECIFICATION forming part of. Letters Patent No. 255,507, dated March 28, 188.2.

Application filed January 31, 1882. (No model.) I

To all whom it may concern:

Be it known that I, EBENEZER HOLMES, of Chicago, in the county of Cook and State ot' Illinois, have invented certain new and useful Improvements in Grain-Bins; and I do hereby declare that the foilowing is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and to the letters ot` reference marked thereon,which form a part of this specitication, and in which- Figure l represents a partial transverse section ot' a grain-elevator having my improvement; Fig. 2, a plan view of a series of the grain-bins in an elevator, and Fig. 3 a secl tional perspective view ot' several grain-bins.

Similarletters designate corresponding par ts in all the gures. n

A denotes the lower story of a grain-house, in which the cars or teams are loaded or unloaded; BB, the bins for storing the grain; and C, the licor above the bins, from which the grain is spouted into any one ot the bins from the elevator or scale-hoppers. The bins B B are generally7 from live to thirteen feet square and from l'orty to sixty feet deep, cach with a hopper-shaped bottom, b, that is provided with aslide or valve for discharging the grain from the bin.

For the purpose ot' building the .bin-walls of a sufcient strength to resist the side pressure ofthe grain when piled to such a height, these walls are generally constructed of solid timber by spiking planks two inches thick, and,

according to the size and height ofthe bins,

either four, six, or eight inches wide,`one tlat upon the other, and so as tobreak joints with every course, and that the planks ot' the longitudinal walls will alternately interlock with the planks of the transverse walls.

Whenever a bin has been entirely emptied, and before it is to be refilled with another' kind or quality of grain, its bottom should be cleaned ot' any remaining grain or dust, for which purpose a man is sent down with a broom, and means have to be provided for said man to climb from the top down to the bottom ot the bin. v

Heretofore rectangular frames made of veeighths-inch round iron were secured into the binwalls aboutevery sixteen or eighteen inches vertically apart, and so as toiproject equal distance from each side ofthe bin-wall, for forming the steps in two adjoining bins. These fr'ames were placed between the several courses ot planks at the proper height by notching the top ot' the planks for the step-frames to be inserted, and than secu-ring them by the next course of planks, being spiked on top, and this was repeated every eighth or ninth course ot' planking.

As will be noticed, with rectangular frames thus placed and secured a vertical row of them could furnish steps only for two bins, and when the notches were made alittlelarge these frames slid laterally in the partition and did not give a sure foot or hand hold to the man climbing up or down.

Now, my invention consists in forming the steps of round iron rings d, secured between the planks at the junction of a longitudinal and transverse bin-wall, and so as to project equal distances into each ot' the four adjacent bins. For this purpose everyeighth or ninth course of two-inch planking thatforms the binwalls is notched out for inserting a ring, d, and then the next above course ot' planking being placed uponit and secured by spikes will hold said ring rigid in its position.

The advantages gained by the ring-shaped steps are, iirst, that bar-iron is much easier bent. to the form of a ring and welded than to bend it to a rectangular shape and weld it; second, that for forming steps in a series ot' grain-bins but onehalt` as many ring-shaped step-frames will be required'(each ring providing steps in four adjoining bins) as with rectangular fraines, each of which provides steps only in two adjoining bins; third, that a ringshaped step is held more rigidly in the notches ot four planks than a rectangular frame will be held in the parallel notches ot' one plank fourthly, that the steps thus formed in the corner ot' a bin give a better hold for ay man to climb upon and less chance for his feet to slip than where rectangular steps project from one ofthe side walls; and, lastly, that by the use of the ring-shaped stepsiaigreatfsavinglinmaterial and labor is obtained.

What I claim isl. In grain-bins, and in combination there- IOO with,theringshaped step-frames builtinto the In testimony that I claim the foregoing as ro partitions between four adjacent bins, substanmy invention I affix my signature in presence tially in the manner set forth. of two witnesses.
