IMPROVEMENT IN RECEPTACLES FOR STORING LIME.

Specification forming part of Letters Patent No. 172,105, dated January 11, 1876; application led Y November 22, 1875.

To all whom it may concern:

. Be it known that I, EDWARD B. ENG- LISH, of Philadelphia, Pennsylvania, have invented an Improvement in Receptacles for Storing Lime, of which the following is a speciiication:

My invention is based on the mode of protecting unslaked lime for which Letters Patent No. 118,680 were granted to Henry Bisbing, September 5, 1871; and the object of my invention is to constructabiu or receptacle which affords better facilities for storing and removing the lime than the apparatus described'in the said patent.

In the accompanying drawing, Figure lis a vertical section of my improved lime-bin, and Fig. 2 a view illustrating my invention as applied to a railroad-car.

The apparatus described in the patent ot' Bisbing consists of a box or receptacle with double walls, having intervening spaces packed with plaster-of-paris or other equivalent material, for absorbing the moisture of the atmosphere, and preventing it from gaining access to the contents of the receptacle,

which was furnished with double sliding doors.

This structure, as described in the said patent, did not afford facilities for the ready introduction and withdrawal of the lime, owing to the difficulty of, and the delay incurred in, the removal and replacing of the sliding doors. Hence, I construct a lime receptacle or bin inthe. manner illustrated in Fig. l, in which A represents the front, B the rear, C the inclined top, and D the bottom, of the bin, all these parts consisting of double walls of wood, with intervening spaces packed or lined with pulverized or line lime, or other equivalent material, for excluding moisture.

When the bin is erected against the wall oi' a building the latter may constitute one of the walls oi' the bin.

In the front wall of the bin are two door- I ways, a and b, the upper doorway being furable tackle, by which lthey may be readily opened and closed.

Each door is so constructed that, when closed, it will exclude the moisture of' the atmosphere from the bin. Thus, the upper door is shown as made with a chamber packed with absorbent or nonconducting material, the edges of both doors being furnished with a padding or packing, which fits snugly to the opening ofthe doorway.

Since the lime has the effect of causing the wood to shrink, the doorways would, in a i wood, with intervening lay ers of paper or other material of equivalent character.

. The lime brought from the kilns is passed through they upper doorway into the bin, where it remains unexposed to the atmosphere until a supply is required for immediate use, when the lower door is opened, and the desired quantity removed and placedin cars or carts for transportation to the point where its use is required.

The bin is preferably erected at such a height from the ground that the lower edge'of the Vlower door shall be on a level, or slightly higher than the bottom of the cart or other vehicle into which the lime has to be loaded from the bin. In some cases it may bel most convenient to place the upper doorway at the top of the bin, so that the contents of cars on an elevated railroad may be discharged directly through the said opening 5 and, in some cases,

the lower door may be at the bottom of the bin, and the lime may be discharged from the same through an inclined chute.

A bin constructed with doorways and doors,

substantially as described, may be attached to, or form a part of, a railroad-car, as shown In testimony'T whereof I have signed my in Fig. 2, so that; the lime may be e'ectually name to this specication in the presence of two protected during its transportation from the subscribing Witnesses.
