ATENT KNIFE FOR CUTTING BARREL-STAVES.
SPECIFICATION forming part of Letters Patent No. 372,998, dated November 8, 1887.
Application filed March 19, 1887. Serial No. 231,493.
To all whom, it may concern.-
Beit known that I, WILLIAM E. WOODROW, a citizen of the United States, and a resident of Cambridge, in the county of Dorchester and State of Maryland, have invented certain new and useful Improvements in Knives for Outting Barrel-Staves; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of a machine for jointing barrel-staves provided with my improved knife or cutter. Fig. 2 is a view of the knife or cutter. Fig. 8 is a View of the die. Figs. 4 and 5 are sectional views of the knife or cutter and of the die. Figs. 6 and 7 are views of a modified form of the knife or cutter and of the die. Figs. 8 and 9 are sectional views of the same. Fig. 10 is a view of astave cut with the knife and cutter, and Fig. 11 isa View of a barrel made from the staves.
Similar numerals of reference indicate corresponding parts in all the figures.
My invention has relation to knives or cutters to be used in that class of machines for jointing barrel-staves having a reciprocating cutter and a stationary die; and it consists in the improved construction and combination of parts of such a cutter and diewhich may cut notches in the edges of the staves for the purpose of having registering-notches for ventilated barrels, as hereinafter more fully de scribed and claimed.
In the accompanying drawings, the numeral 1 indicates the cutter, and 2 is the die, which parts are secured,respectively,in any suitable manner to a reciprocating frame and to a stationary bed, the reciprocating frame 3 having its ends suitably guided in frame-pieces 4 and having means for drawing it downward, a treadle, 5, being shown in the drawings for that purpose. 6, and this-cutting-edge consists of straight portions 7 and laterally-curved portions 8, curved to one side. The die is formed with registering straight and flat portions 9 and with concave portions 10, and it will be seen that when a stave, 11, is placed between the The cutter has a sharp lower edge,-
(No model.)
standing at an angle to the plane of the cutter and die, so that the straight cutter will cut more off at the ends of the edge of the compressed and bulged staveblank than at the middle, giving the stave the proper shape for forming the bilge of the barrel, while the curved portions will cut notches in the edge of the stave, which notches 12 will register with each other when the staves are joined together in a barrel forming ventilating-apertures 13 in the sides of the barrel, which apertures will be sufficiently regular to cause the barrel to have a neat and finished appearance, while having ample veutilatiomrendering the barrel more desirable than the common barrel having holes choppedin the sides for ventilation,and rendering the manufacture of this barrel no more costly than the manufacture of barrels with plain staves, the notching being accomplished while, jointing the staves without being accompanied by any additional labor or expense. The knife or cutter is preferably formed as shown in Figs. 4 and 6, the knife being formed from a flat piece of steel,which is pressed or rolled between suitable dies or rollers to form corrugations forming the curved portions of the edge, the corrugations 14 extending the entire width of the blade and being pressed through the entire thickness of the metal,and the cutting-edges of the curved portions are ground from the concave side,forming clear rounded. or curved cutting-edges. The concave portions of the die are extended the entire width of the die when it is used with this form of cutter, which I prefer to use, as it is cheaper of manufacture and more accurately made than a cutter made in any other man ner, the curves being made before the steel is tempered, and consequently being made while the metal is pliable and ductile.
In the four figures representing the modified form of the cutter and die the cutter is shown as having the curved portions ground out of a straight blade from one side and the straight portions ground out from the other side, and the die is shown with the concave portions ground out to correspond in shape to the curved portions of the cutter; but although the cutter and die may be made in this manner, I prefer to make them in the first-described manner, as the cutter is less expensive to manufacture than the other form and the cutter may be continually ground until it is entirely ground out without changing the shape of the curved portions, while in the other form the curved portions and straight portions are liable to change shape as they are ground, being ground from opposite sides, while in the first form of cutter the grinding is all done from one side and-the shape of the curved portions does not depend upon the grinding of them.
Having thus described my invention, Iclaiin and desire to secure by Letters Patent of the United States In a machine for jointing compressed staves VILLIAM E. \VOODROWV.
