I11 my case, however, the two plane surfaces which make the V projection or recess, as thecase may be, cover the whole edge of the stave, so that in each case the edge is formed wholly of'two inclined plane faces, which, starting from the inner and outer faces of the stave, meet and in- This construction is of material advantage in severalrespects, as will i be hereinafter pointed out.

In an ordinarytbarrel the stav esfhave plain and destroy the arch of the barrel, thus rendering the package f crazy. Bymy improve ment the staves are so interlocked as to obtain very much greater strength and stability. At

thesame time the barrel has a certain elasticity', which permits it to spring and yield to blows to a certain extent when being handled,

for the faces I) b and a a can move on one an-' base of the wedge, the edges fitting closely to gether at these points, while the apex of the In order to join and interlock the staves wedge does not touch the bottom of the recess. Ioo

' In this way the elasticity and springiness of the barrel is increased, and it has imparted to it a ing also to the joint between the heads of the barrel and the body, which will presently be described. The faces and edges of both the staves and the heads, presenting only planes and straight lines, enable the manufacturer to do the entire work with ordinary tools, or even buzz-saws, instead of necessitating the employtools ground I 'withlongitudinaledges, each composed of: two

inclined-plane surfaces, which start, respectively, from the inner and outer faces of the ment of specialmachinery orof to curves and angles.

The staves should be crimped'with-rollers or otherwise to take a permanent set with: suitable shape for a bilged barrel, so that in, set-- ting up thebarrel the projecting edge of one stave will readily enter the V-recessed edgeof the other stave, and the staves of the whole circle of the barrel will readily come together, and will not neediheating. andtrussing.

WVith a view to remove,- as far aspracticable, the tendency of the headto work out of place and press the staves apart, toenhance its capacity to resist the j arsandlblowsrwhich occur during the handling of the filled barrel,

and at thelsame time to so secure the head'ias toabsolutely prevent it fromrbeingforced'dnward by outside blows or pressure, I@ use a head, B, representing the fru'stum of a. right cone, the planes of which-are parallel, the base of the frustum beingnpon the inside'of' barrel when the head is inplace.

the base of which presents a square shoulfder, upon which the larger diameter or inner side of the head is to rest.

Thus the conical head heretofore described, when in place, is in As it itcannot be pressed farther into the barrel by any externally-applied force, nor will it have any tendency to strain on the hoops or to press the staves apart, as it would were its periphery beveled or wedge shaped.
