PACKING-CASE.

SPECIFICATION forming part of Letters Patent No. 237,874, dated February 15, 1881.

Application filed January 3, 1881.

To all whom it may concern Be it known that I, RALPH S. JENNINGS, of Baltimore city, State of Maryland, have invented certain new and useful Improvements in Packing-Gases; and I hereby declare the same to be fully ,'clearly, and exactly described as follows, reference being had to the accompanying drawings, in which Figure l isaside elevation of the body-blank. Fig. 2 is a vertical sectional view of the edge of the body on an enlarged scale, showing the direction of the grain of the wood; Fig. 3, a side elevation of the interior side of the longitudinal seam; Fig. 4, a perspective of the interior of the case 5 Fig. 5, a sectional view of the head-joint. and Fig. 6 a side elevation of one end of the case.

My invention relates to. packing-cases in general, but more particularly to such as are designed to contain pulverulent material and it has for its object to provide a case which, by reason of its strength, toughness, cheapness,

and elasticity, is adapted to subserve the ends of bagging or plank cases, and which, by reason of its imperviousncss to water, is fitted for many uses for which barrels have heretofore been deemed necessary.

The above characteristics render the case of such almost universal availability as to make the mention of the uses to which it may be putunnecessary.- It is mainly designed, however, for packing fertilizers, which in the case of so-called fsuperphosphates or acid phosphates are so corrosive in their action as to speedily rot and spoil the bagging in which they are packed. This prevents them from being kept for any great length of time in the bags. In the case of Peruvian guano or other fertilizing compounds consisting wholly or in part of the deposits from the guano islands or bat-caves, the odor of the material is so pungent and ofiensive that a practically air and water tight package has long been a desideratum. I have succeeded in constructing a strong and water-tight package at a figure which will admit of its use in packing even cheaper material than fertilizers.

In the drawings, A is the body of the package, which consists of two or more (preferably three) layers of veneer, c c 0", the outer and (No model.)

inner layers having the grain horizontal, while that of the middle layer is vertical. They are cemented together by means of any suitable cement, a composition of about eleven parts of pitch to one of dead-oil answering well. The longitudinal seam d is secured by stitching, and the heads are attached to the walls by means of strips of bagging or burlaps F, that are secured by stitching a to the edge of both walls and heads, and are overseamed, as shown atf, forming a soft and yielding chine, upon which the package may be trundled. Now, the stitching a. is liable, by reason of the close contiguity of the needle-holes, to cause the veneers on the outer and inner sides of the walls A to splita result which was conduced to by the approximate parallelism of the grain to the line of stitching, both being substantially horizontal. To obviate this I stitch (as at a) or cement to the outer walls a strip, B, of veneer having the grain vertical or inclined, and in case it'is stitched I make its lower edge curved, scalloped, or sinuous in outline, so that the stitches, which are parallel to its edge, cross the grain of the inner and outer layers, 0 a, and splitting of the same is prevented and the chine of the case is strengthened.

The burlaps F'is waterprooted by inaking it double and interposing a layer,f, of the p i tch a d gga d gil or equivalent water-proof composition- ,To protect the stitches on the inside from the corrosive action of the contents of the package, I cover the longitudinal seam d with a strip of veneer or other suitable material, C, and spring a veneer hoop, D, around the inside, near the heads, and over the line or lines of stitching. The heads themselves are lined with a sheet, E, of veneer, which covers the open joint between the heads and body. (See Fig. 5.)

To facilitate the handling of the package I secure at opposite points, nearits edge, at either end, ears '5 z', of burlaps or bagging. It will thus be seen that the package is lined inside with wood, and with wood aloneno stitches are in contact with the contentsand that the heads are secured to the walls by a waterproof joint.

No claim is herein laid to the mode of attaching the heads-namely, by a sheet or flap of textile fabric covering the open joint between the heads and body-as that is the subject of another application for Letters Patent,

What I claim is- 1. A composite veneer package having the grain of its exterior layer horizontal, and havin g a re-enforcin g strip surrounding the edge of its body and a textile-fabric flap stitched to said strip, as and for the purpose setforth.

2. A composite veneer package having the grain of its exterior layer horizontal, and having a re-enforcing strip secured around the edge of the body, the said strip having its grain vertical, and being secured to the body by a line of stitching parallel to its curved lower edge, as set forth.

joint, as set forth.
