BARREL STAVE.

' Application .filed December 19, 1921. Serial No. 523,306.

To all whom z't may concern:

' Beit known that I, I'IERBERT J. SMITH, a subject of the Dominion of Canada, and resident of" Kearny, in thecounty of Hudson and State of New Jersey, have invented certain new and useful Improvements in Barrel Staves, ofnwhieh the following is a specification.

outside The invention relates to barrel staves formed of paperboard and the method of making the same, and has for its object to provide a stave comprising avbody of paperboard, preferably including a series of plies of paperboard united by a suitable binder or adhesive, which latter will temporarily moisten the blank sufficientlyto enable the same to be pressed into its ultimate form, which includes longitudinal and transverse curvatures and the narrowing of the staves from the middle toward the ends. mation of the stave is eflected by pressing the softened paperboard blank to impart the desired curvature thereto, and at the same time forming in the body of the blank an intermediate longitudinal groove which increases in depth and width from the center toward the ends, and transverse grooves near the ends which increase in depth and width from the intersection thereof with the longitudinal grooves toward the lateral edges.

The invention is illustrated in the 'accom panying drawing, in which:

Figure 1 is a perspective view of a suitable paperboard blank for forming a stave;

Fig. 2 is a plan view of a complete stave looking toward the inside;

Fig. 3 is an end elevation of the same; Fig. a is a plan View of the stave from the Fig. 5 is a fragmentary sectional perspective view showing the mode of 'applyinga hoop and head to the barrel, and

Fig. 6 isa perspective view of the complete barrel.

Referring to the drawings, 1 indicates the paperboard blank'for forming a single stave, the same preferablycomprising a series of plies of rectangular sheets of paperboard, united by a suitable adhesive, such, for example, as'silicate of soda, which will havev the efiect of first'softening the blank to render the same more or less plastic and pliable, and subsequently to'set or harden and retain the blank in the ultimate form imparted thereto by the succeeding operations.

Such for- WVl iile the blank stillplastic or. soft, due

tothe action of the adhesive, it is placed in a. suitable press, which reducestheblank to 7 its final stave like; form,. namely, with the proper bilge produced by imparting a longitudinal curvature from end to end and a transverse curvature from side to side. During the pressing operation there is formed in the blank a median longitudinal groove 2, which increases in depth and width from the center of the blank toward each end, said groove comprising a relatively narrow shallow middle portion and outwardly'flaring deepening end sections 3 which have the effect of producing thenecessary taper of the stave from the middle section toward the ends. In addition to these grooves 2, there is also formed during the pressing operation [transverse grooves in the respective ends of the staves,wh1'ch grooves increase in depth d i and width from the intersections thereof withthe longitudinal grooves toward the lateral edges of the blank and provide inwardly projecting ledges 5 to support the barrel heads 6 and channel-like elements? to receive the hoops 8. These longitudinal and transverse grooves also constitute material reenforcing or strengthening elementsfor each stave so that the staves maybe handledand shipped without danger of deforming the same. I

In this particular. form and structural arrangement of the staves as illustrated, eight units are sufficient to form a barrel, and

when assembled in the usual manner and the heads 6 and hoops 8 appliedin accordance p with the standard practice, a very strong and light barrel, as illustrated in Fig. 6, results. When the staves are thus made up nto ai barrel, the inwardly projecting portions of 'thestaves formed by the deep'enedend sections serum grooves 2 overhang the heads 6 and serveto lock them in place onthe ledges 5. V

Nhatl claim is:

1. A barrelv stave comprising a blank of paperboard having a continuous intermediate longitudinal groove therein increasing in depth and width from the; center toward each end of the blank. r

2. A barrel stave comprising a blanket paperboard having an intermediate longitudinal groove therein increasing in depth and width from the center toward each end of the blank,oand transverse grooves near 3. A barrel stave comprising a blank formed of several-plies-of paperboard united by an adheslve, said blank having an inter- V mediate longitudinal groove therein increasing in depth and Width from the center to- Ward each end of thebla nk,

4. A barrel stave comprising a blank formed of'several plies of paperboard united by an adhesive, said blank having an intermediatelongitudinal groove therein increas ing in depth and Width from the'cen'ter to- Ward each end of the'blank, and transverse 15 grooves near each cnd increasingin depth and \vldth from 'the'interseotion thereof with the longitudinal-groove to the lateral edges.

5. A barrel stave comprising a blank of paper board having an intermediate longitudinal groove, and transverse grooves near each end increasingin depth and Width from th'einters'ection" thereof with the longitudinal groove to the lateral edges.

Signed at New York, in the county of New York, and State of New York this 8th day of December, A. D. 1921.
