Specification of Letters Patent.

Application led October 7, 1916. Serial No. 124,309.

county of Henrico, and State of Virginia,`

have invented certain new and useful Improvements in Fail-Bottom Fasteners, of which the following is a full and clear specification. Y,

The object of this invention'is to provide i the lower endof a shipping vessel with a lsheet metal band that will at the same time perform the function of a hoop, a chime, and a bottom fastening, and will also greatly n stiffen and strengthen the lower end of the ment of the combined hoop,

vessel, where the greatest Strength is needed to enable it to withstand. the rough usage these articles are subjected to in transportation.

In the drawings- Figure 1 is a side elevation of a portion of the bottom of a .candy pail or other`shipping vessel constructed in accordance with our invention;

Fig. 2 a vertical section thereof;

Fig. 3 a horizontal sectional view showing the band in process of being fastened;

Fig. 4 a detailview showing the band being pressed into position; and

Fig. 5 a detail perspective view of a fragchime, and bottom fastener.

In the drawing annexed, laf. designates the body of the pail or other vessel, and t the bottom thereof, which fits up against the bottom edge of the pail body. To clamp the pail body in place, we provide a sheet metal band c which closely ts the pail at the bottom edge thereof and is fastened Securely to the exterior of the pail by any suitable means, preferably by nail-like points d lntegral with the band and driven into the pail body and clenched on the interior thereof, as fully disclosed and claimed 1n our co-pending application Serial No.'l

94,158, led April 28, 1916.

The lower edge of the band is bent inwardly and upwardly to form an annular chime e of arch form in cross-section, the extreme edge of this chime portion pressing against the lower face of the bottom and serving to clamp the same hard up against the lower edge of the pail body.- The edge of the bottom fits solidly against the 4inner face of the band, so that the bottom is held rigidly in place without extraneous fastening devices.

It will be observed that our device serves the three-fold function of a hoop for the lower end of the pail body, a fastening means for the bottom, and also as a chimelike foot flange for the pail, this flange being arch-like in cross-section to obtain the 'maximum of strength for any given thickness of sheet metal. In this way, we provide an exceedingly simple and inexpensive way of Vfastening the bottom of the pail and at the same time strengthen the pail just where the greatest strength is needed, and it will be observed that these advantages are obtained withoutexposing the contents of the pail to any metal surfaces, except the inner clenched ends of the points d, the parts of these points that are exposed on the interior being so small as to be negligible.

It will be observed that the free edge of the arched chime e bears against the bottom on an annular line at a distance from the inner face of the pail wall. The result of this is that when this inner annular edge is pressed hard against the bottom all around and the bottom is made of thin material, the bottom "will be slightly bulged upwardly at its center, thus slightly arching the bottom upwardly. This not only insures a very tight joint between the bottom and the lower edge of the fp ail body, but also insures maximum strength in the bottom and in the pail structure. `With the bottom thus arched upwardly, it will be observed that it will more ei'ectually resist strains due to the weight of the contents of the pail, and it will be observed that a material part of the strain due to the weight of the contents will be taken up in a sort of circumferential thrust against the free edge of the chime, thereby tending to hold the bottom tight against the bottom edge of the pail body. It will be observed also that the free edge of the chime e is forced into the lower face of the bottom and forms a groove therein, thereby anchoring the free edge yof the chime in the body of the bottom at a distance from the rim thereof, whereby the bottom and the ce will Patented ai. is, raie. f

sufficiently hard to force the free edge of the chime to form a groove in the bottom member, and then, while thus held tightly in place, the anchoring devices d are driven into the body of the pail.

Having thus described our invention, what we claim is:

l. The combination with a cylindrical shipping vessel having a grooved bottom fit.-

-ting up against its lower edge, of ametal band fitted around the bottom ofthe vessel and having its upper edge anchored thereto and its lower edge depending below the bottom and bent inwardly and upwardly, the upwardly-bent edge being pressed against the under surface of the bottom and forcibly in'to said groove, to thereby clamp the bottom against the lower edge ofthe pail and support the bottom entirely upon the said edge, said edge serving to hold said bottom against lateral displacement.

2. The combination with a cylindrical body and a bottom vfitting up against the lower edge thereof, of a combined hoop and chime and bottom fastener having an annular arched portion whose edge is anchored rigidly in the under surface of the bottom at a distance from the edge.

3. The combination with. a cylindrical body and a bottom fitting up against the lower edge thereof, of a combined hoop and chime and 'bottom fastener having an annular arched portion whose edge is4 anchored to the under surface of the bottom at a point inside of the inner face `of the body of the vessel.

4. rlhe combination with a `cylindrical body and a bottom fitting up against the bottomv edge thereof, of a combined hoop and chime and bottom fasteneroonsisting of a band embracing thel lower edge of the body and the edge of the bottom and having an-` choring means at its upper edge engaging the cylindrical body and an arch-like chime formed at its lower edge, this chime extending inwardly and upwardly and being anchored in a groove in the lunder surface of the bottom. Y

5. In a cylindrical vessel, a bottom fitting against the lower edge of 'said vessel, and

a Inet-al band surrounding the lower edge of the vessel and anchored thereto, the lower annular edge of this band extending beyond lthe lower face of the bottom and being curled inwardly t'o an arch form in cross section, the upwardly-directed annular edge of this archlike portion being forcibly embedded into thebottom at a point inside of the plane of the wall of the vessel to thus clamp the bottom against the lower edge of the vessel and cause the bottom to arch upwardly, the bottom being supported entirely on said upwardly-bent edge.

in testimony whereof we hereunto affix our signatures this 6th day of Gotober, 1916.
