BOX-PILE.

SPECIFICATION forming part of Letters Patent No. 550,109, dated November 19, 1895. Application filed. January 17, 1995. erial No. 536,213. (No model.)

To all whom it may concern:

Be it known that 1, JOHN H. POOLE, of St. John, in the county of St. John and Province of N GW'BIIIDSWICk, Canada, have invented certain new and useful Improvements in Box- Piles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof.

My invention, which will be hereinafter fully set forth and claimed, relates to the construction of piles for heating previous to roll- 1ng.

The object of my invention is a skeleton or box for scrap -piles, together with an improved method of building up the material to be rolled.

Figure 1 is a transverse section of my improved pile-box or skeleton pile. Fig. 2 is a side elevation of the same. Fig. 3 is a perspective view of the same, showing a modification consisting of an extra hoop over the top. Fig. 4 is a perspective view of a scrappile, one of the skeleton plates being omitted. Fig. 5 is a perspective view of a scrap-pile similar to that shown in Fig. 4, but somewhat modified.

I construct a skeleton or box of two side plates A, set on edge a distance apart, which I prefer to roll about half an inch thick and with longitudinal grooves a, one inside about the'center and two outside near the edges. Said grooves are not indispensable, but-facilitate the making of a lighter plate, are more easily punched through said grooves, and cause the bands or tiles to lie flat on,the sides. In each of said plates are punched near the upper edge two or more holes a, one

near each end and preferably through thegrooves, if there are such. Near each end is placed a band, tie, hoop, or clip 13, passing across the bottom edges and up the sides and having their ends turned inward and inserted in the holes a. For said bands or ties half or quarter round iron is preferable, the flat side lying against the plates. Another such tie B may be passed over the top in the center, as shown in Fig. 3.

In making up scrap-piles long scrap-iron bars or plates may be put on the bottom, supported on the cross portions of the bands or ties B, and smaller scrap may be put on the top. When using scrap-steel=such as crop ends of steel plate or bars, nail-butts, old rails, and the like a flat bar or plate with ends turned up is put in the bottom of the pile or a layer of scrap-iron on the bottom and ends of pile and the center filled in with scrap-steel, covering the top with flat bar or plate or pieces of scrap-iron. The joints may practically be made air-tight by filling them with turnings or borings, as they will flux before the steel is affected, and thus seal the pile and prevent oxidation of the interior. Plates similar to the plates A may also be used on the bottom and top of the pile, if preferred.

The filling and size of the piles will of course vary with the nature and size of the sections to be rolled.

A pile thus constructed will be entirely coherent and may be freely handled, charged into the furnace, and removed therefrom to the hammer or rollers and formed into plates, bars, or any desired section.

I claim as my invention-==.

1. In a skeleton pile, the combination of two side plates A placed on edge a distance apart and having holes a near their upper edge and two or more bands hoops or ties 13 each passing across the edges of said plates and up or down the sides and having their ends turned and passed into said holes in the plates, substantially as set forth.

2. A skeleton pile, consisting of two plates A having one or more longitudinal grooves a with holes a. punched in one of said grooves near the upper edge of the plates and bands hoops or ties B near the ends of said plates and passing under and across the bottom edges and up the sides of said plates and having their ends turned and inserted in said holes a, substantially as set forth.

3. A pile consisting of a skeleton made of side plates set on edge and held together by bands or ties passing across two of the edges and having their ends inserted in holes in said plates, a plate at the bottom supported on said bands or ties and having its ends turned up and small scrap in the center and a plate or bars on top and having the joints filled with turnings or borings, substantially as set forth.

In testimony whereof I have signed in the presence-of the undersigned witnesses.

JOHN H. POOLE.
