KNOCKDOWN BARREL.

Specification of Letters latent.

Patented Nov. 10, 1914-.

Application filed November 13, 1913. Serial No. 800,887.

To all whom it may concern Be it known that I, ALBERT J. BUHTZ, a' citizen of the United States, and resident of Seattle, King county, \Vashington, have invented certain new and useful Improvements in Knockdown Barrels, of which the following is a specification.

My invention relates to barrels and particularly to knock down barrels, or barrels so constructed that they may be disassembled for shipping when empty.

The object of my invention is toproduce an improved and more practical type of construction, whereby the barrels may be partially assembled into segmen s which will nest for compactness of transportation and maybe easily and cheaply as'sembledwhen they are to be used.

My invention comprises the novel parts and combinations of parts which will be described in the specification and defined in the claims. 7

In the accompanying drawings I have shown my invention in the form which is now preferred by me.

Figure 1 IS an end view of a barrel con structed in accordance with my nvention,

the construction being that used where the head is to be removable and the head being removed. Fig. 2 is an elevation and partial section of a barrel end. Fig. 3 shows in perspective one of the segmental binding strips used for the staves at the end where the head is to be removable. Fig. 4 is a perspective of a segmental binding strip as made for the end of the barrel where it is not required to remove the head. Fig. 5 shows, in perspective and nested as they would be for shipment, the three stave segments which may be used to form'the body of the barrel shown in Figs. 1 and 2. Fig. 6 shows the. removable head. Fig. 7 is a section of a corner of a barrel showing how the head is secured in place and the corrugations by which the bindings are more securely held in the staves. Fig. 8 is a cross section of a stave binding before it is put in. place.

In my invention I assemble a number of staves so as to form a segment of the completed barrel. The size of these segments,

that is, the number which would be required to make a barrel, may be somewhat varied, but I consider the most practical number to be three, and have showna barrel having the staves previously assembled into three like segments. The staves are supposed to be of wood and, in general, of a standard type of construction. The staves 1 as Izhave herein shown them, do not have chamfered chines, nor are they crozed to receive the head.

A number of staves l, sufiicient to form a segment of the desired width, are secured to- 4 gether by sheet 7 metal bindings 2 and 3, placed at opposite ends, these being longitudinally curved to conform to the curvature of the barrel. The binding pieces 2 and 3 are alike, except that the pieces 2 are modified in one wa to permit ready insertion and removal 0 the head 4 after the barrel has been completely assembled. Each piece 2 and 3,'is bent over the ends of the staves, so as to incase their ends. A section 20 extends from the outer end corner of the staves toward the center; the section 21 extends over the ends of the staves and the-section 22 extends alongthe inner surface of the staves to a point substantially coincidentwiththe outer surface of the head, where an inwardly projecting flange 28 is formed by bending the metal upon itself. Themetal then 0011-.

tinues toward the center of the barrel as a section 24: of a width substantially equal to. the thickness of the head-4 and is then bent invirdly to form a flange 26w'hichengages the inner surface of the head. v

in the binding strips used for both ends of the barrel, but the one which is placed at the end of the barrel which receives the removable head, is modified by having sub-- stantially one-half of the length. of the fiange23 cut away. The portion cut awaymay be concentrated in one cut, as I'have shown in the drawings, or it may be divided intoseparated parts. The head 4,- which is placed in this end of the barrel, has its edge notched, or recessed to conform to the sections of the flange 23 which remains. That is, the gaps 4C1 match the sectionsof the flange which remain and the projecting parts 40 match with the gaps in the flange. In in- I I The above constructions are found alike serting the head the projections 40 are,

shaped to the required form. At this time the cross section would be as shown in Fig. 8. To securely bind the whole together, certain partsof the binding piece preferably those which lie in the plane of the head, are crimped or corrugated, as shown at 25, the corrugations being ressed into the wood. These corrugations siiould preferably be offset from the normal plane of the plate, wholly at that side which is next the staves, as is shown in Fig. 7. These corrugations would thus be embedded in the staves and would then appear as shown in Fig. 7 The barrel segments thus formed may be nested, as shown in Fig. 5, for convenient shipping, the heads and hoops being also bundled. When the barrel is to be assembled, the segments which form the complete barrel are brought together and the bottom head inserted between the flanges 23 and 25 and hoops placed upon the barrel and driven tight. In Figs. 2 and 7 I have shown wire hoops 5, although any kind of hoops may be used.

By reason of the fact that the bindings employed to secure together the staves of a segment are made of sheet metal which hugs closely to the surface of the staves and by reason of their location at the ends of the staves, or at the chines, where the barrel is of the least diameter, they do not interfere with the application or removal of hoops of any of the kinds most commonly used. By reason of the fact that they embrace or are folded about the chines and further because of the inwardly projecting, head-holding flanges, they have a sufficient transverse depth in the direction of the diameter of the completed barrel, to give them such stiflness as will cause them to hold their shape under any ordinary handling conditions.

at I claim as my invention and desire to patent is:

1. In a barrel, in combination, staves, means permanently joining the ends of a plurality of staves to form separable and distinct segments, said rreans being provided with head securing members, and means for to form separable and distinct segments, said bindings at one end of the barrel having two inwardly projecting flanges separated lengthwise the barrel to receive the barrel head therebetween, and means independent of the said bindings for securing a plurality of the segments together to form a barrel body.

4. As an article of manufacture, a barrel segment composed of a plurality of bilged staves having metal bindings fixedly secured over their chines, said bindings being provided with head holding means and having transverse stiffness which maintains the curvature of the segment in conformity with that of the completed barrel.

5. In a barrel, in combination, staves, a sheet metal binding embracing the ends of a plurality of staves to form a segment, said binding being folded to, form two inwardly projecting flanges adapted to receive the head between them, the part of the metal connecting said flanges and the corresponding part of the outside arm of the binding having inwardly extendin projections embedded in the staves, and hoops securing a plurality of segments to form the barrel.

In testimony whereof I have hereunto aflixed my signature this 7th day of November, 1913.
