IMPROVEMENT IN VENEER-CUTTING MACHINES FOR BARREL-MAKING.

Specification forming part of Letters Patent No. 182,499, dated September 19, 1876; application filed February 19, 1876.

To all whom it may concern:

Be it known that I, JASPER A. WATERMAN, of Reading, in the county of Hillsdale and State of Michigan, have invented certain new and useful Improvements in Veneer-Cutting Machines for Barrel-Makin g, of which the following is a specification:

This invention has for its object the forming of a barrel without staves, the body of the barrel being made of a continuous roll or sheet of wood cut from a log, and having the proper bilge-projection given to it in the cuting, and not formed by goring, as has heretofore been the case.

The machine for efiecting this purpose is fully described as follows In the accompanying drawing, forming part of this specification, Figure l is a front eleva- 1 tion, Fig. 2 a vertical transverse section, and Fig. 3 a plan, of the machine.

In these figures, A is a frame, provided with a curved knife, B, which knife is adjusted in its bearings by the screws 0 G. The frame A is set close up to any suitable log already centered in a lathe. As the said log revolves in the lathe, it is obvious that the knife A will rapidly reduce it to a continuous sheet as long as it is fed up to the log. Near each end of the knife A is a beveling-knife, D, and near each knife D are two cutters, 6 6 The outer cutters e e cut the sheet of wood to the de sired length for the height of the barrel, and the inner cutters e 6 out the croze in the barrel-sheet, while the beveling-knives D D form the chimes. As the sheet of wood thus out passes from the knife A, it is guided through and between the two rolls F F between which rolls the sheet has its bend reversed, so that vthe crozes and chimes are set to the inside of the sheet. The roll F, being a former, or facsimile of the diameter and length of barrel, is provided with a longitudinal knife, Gr, which at every revolution of the roll F severs a length of wood sufficient to form the circumference of the body of one barrel. The said knife, instead of being a straight line, may be curved or irregular in shape at its cuttingedge, so that the seam of the barrel shall not form a straight line, but shall be either a curved line, or a line made up of a series of curves or broken lines. The two rolls F F are mounted in suitable bearings, and a rubber or other spring unites the two rolls, in order that sufficient spring may bepermitted to the roll F to allow for the projection of the knife G beyond its surface.

By the coaction of these several devices, a most eflicient and simple machine is made to continuously turn out barrelblanks all ready for hooping and heading.

Having thus fully described these improve ments in machines for making barrels as of my invention, I claim-- 1. The curved knife B, for cutting a bilgeshaped sheet of wood, in combination with rolls F F, substantially in the manner hereinbefore described, for the purpose set forth.

2. The combination, with the knife B, of the shaping-roll F, provided with the knife Gr, whereby a sheet of wood is cut from a log, and formed with a bilgeprojection into a barrel-blank, substantially in the manner hereinbefore set forth.

3. The combination of the roll F, provided with the knife G, with the feed-roll F whereby a sheet of wood is both fed from a log and cut into a barrel-blank, substantially in the manner hereinbefore set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

JASPER A. WATERMAN.
