IMPRCVEMVENIT IN PAPER BARRELS.

Specification forming part of Letters Patent No. 176,869, dated May 2, 1876; application filed September 18, 1875.

To all whom it may concern:

Be it known that I, GEORGE W. LARAWAY, of Port Byron, county of Cayuga, and State of New York, Vhave invented certain new and useful Improvements in Barrels; and I do hereby declare the following to be a full, clear, and exact description of the same, ret'erenpe being had to the accompanying drawing, formand it consists of a barrel made in the manner hereinafter fully described and claimed. I take vegetable or animall fiber, or a mixture of the two, and reduce it to a pulp by any of the well-known processes in common use. The pulp, while in a plastic state, is molded into the form ot' a barrel (shown'in the drawings) by peculiarly constructed molds and pressing mechanism, which I propose to make the subject of a separate patent.

The inner wall of the mold is immovable, while the outer Wallis capable of being powerfully contracted after the pulp has been placed in the recess between them with sufficient pressure to consolidate the fibrous material or materials, driving the Water out of and leaving it as solid and compact as wood. The outer wall of the mold may be made irnmovable, and the inner wall capable ot' being contracted; or both may be made capable of movement. The recess in the mold, when the Wall or walls thereof are contracted, is made of such a form as will produce a barrel having recesses c, enlargements b at eachend to take the place of the 'chine and hoop, and strengthen the ends, and a bilge, a, which may be made thicker than the ends, and project beyond a right line joining the enlargements b, so as to permit the barrel to rock and allow it to be easily turned on end, as is the case with ordinary wooden barrels. Drawing-heads d, made ot' pulp and compressed in molds, tit into the recesses c, and may be fastened therein in any suitable and well-known manner to complete the barrel.

For greater ecpnomy and strength the ends of the barrel may be iliade of stronger material than the-body by filling the lower part of the mold with pulp formed from strong ber, such as manila or the like, for about onethird of the length of the barrel, then filling in pulp of straw, or other cheap ber, forV another third, or to form the body, andthen l iillin g the remaining third with pulp from the same ber as the first third.

I do not contlne myself to making the ends two-thirds and the body one-third of different tibers, as the employment of a dil'erent ber for the ends and body, whether one-third or any proportion suitable, comes within the' scope of my invention. Common stock can thusbe used when desirable, and the barrel left strong at the ends, where strength' is most needed. A

I do not confine myself to the exactV form of the barrel shown in the drawing, as it may be varied without departing from my invention.

What I claim as new, and desire to secure by Letters Patent, is

l. A molded pulp barrel having homogeneousv enlargements and body, substantially as shown-and described.

2. A molded compressed-pulp bilged barrel, substantially as described.

3. A molded pulp barrel, the fibers ot' the ends thereof being of stronger material than those of the body, substantially as described.
