Application July 9, 1942, Serial No. 450,262

3 Claims.

The invention relates to shell carrying receptacles, and more particularly to the liner or protective covering for the shells disposed in such receptacles.

l-Ieretofore, the shell carrier liners have been made from paper by the use of several tube sections adhesively secured together and some of which have to be specially machined and treated before their assembly in the casing. These multiple tube liners, therefore, involve the use of considerable material and considerable labor. The object of this invention is to greatly simplify the construction of shell carrier liners by making a liner formed from pulp fiber tubing or tubing formed by a series of convolute or spirally wound sheets of paper. According to the invention, the tube has a reduced tapered portion to take the neck of the shell and a reduced bore beyond the neck for the projectile, both of these reduced portions being reinforced by ribs formed in the tubing during the process of reducing the tube to the desired dimensions. The product of this invention has greater strength longitudinah.

1y than the usual built-up type of shell carrier liner, and the labor, equipment, and time required for its manufacture are greatly reduced over the usual type of shell liner.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawing:

Fig. 1 is a plan view of a shell carrier liner embodying the invention;

Fig. 2 is a sectional view taken generally along the longitudinal section 2-2 of Fig. 1;

Fig. 3 is a detailed sectional View taken on the line 3-3 of Fig. 2;

Fig. 4 is a detailed sectional view taken on the line 44 of Fig. 2;

Fig. 5 is a detailed sectional View taken on the line 5--5 of Fig.2.

Referring to the drawing, the shell liner embodying the invention comprises a tube having a plain tubular portion 8 to fit over the body portion of the shell, a tapered tubular portion 9 to fit the tapered neck of the shell, and a tubular portion Ill provided with a plain inner liner II to fit over the projectile portion of the shell and form a shoulder I3 which abuts against the upper edge of the shell. The portions 9 and In of the tube are characterized by having a series of radially disposed ribs l4 extending lengthwise thereof and formed by the drawing together of sections of the tube from its original diameter, equal to the diameter of the portion 8 of the tube into a smaller diameter, this drawing or contracting operation-resulting in creating a series of folded portions I5 which compacted together form the ribs l4. At its outer end the rib portion of the tube is provided with a ring [6 fitted over the ribs and being formed by a section cut off from a longer portion of the tubular part 8 of the initially formed tube. This ring 16 being of the same outside diameter as the part B and. the outer diameter of the ribs 14 being substantially equal to the inner diameter of ring l6 and part 8, it acts to keep the liner in a straight position when vertically or horizontally disposed. The shoulder forming tube H is a small plain tubular member that is inserted in the tubular portion I0 after the same has been formed and may be secured therein by any suitable adhesive.

A handl for the casing liner is provided by a strip I! of webbing whose ends 18 extend into the upper end of the liner casing and are secured thereto by washers l9 and tubular metal rivets 20. The lower end portion of the shell casing may be arcuately cut out as indicated at 2|, so that the shell may be grasped at this end by the fingers of the operator.

With this construction the liner casing may be readily formed to fit the shell and acts as a cushion for the shell when in the carrying case with one or more other shell units.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention is:

1. In a shell carrier, a shell liner formed of fiber tubing having a tubular portion shaped to fit the body of the shell, a contracted tapered portion shaped to fit the neck of the shell, and a lined tubular portion shaped to fit the projectile of the shell and form a shoulder to enage the upper edge of the shell casing, said tapered portion for a part of its length and said last named tubular portion having bent contracted wall portions forming radially extending ribs of less diameter than the tubular portion having substantially the same outer diameter as the first named tubular portion.

3. In a shell carrier, a shell liner formed of fiber tubing having a tubular portion shaped to fit the body of the shell, a contracted tapered portion shaped to fit the neck of the shell with parts thereof overlapping each other to form radially disposed outer ribs extending length- Wise from an intermediate diameter to the smaller diameter of said tapered portion, and a tubular portion of reduced diameter for the projectile of the shell and having overlapping wall portions forming a continuation of the ribs of said tapered portion.
