'.IO ALIi WIIOM IT MAY CONOERN:

Be it known that I, WILLIAM Snnvrss, ofSidney, i n the county of Shelby, and State of Ohio, have invented certain new` and useful Improvements in Apparatus for Soldering Tin Cans; and I do hereby declare that the following is a full, clear, and exact description ofthe same, refe-r'nee being had to the accompanying drawings, making a portion of this specification, in which- Figure 1 is a side View of an apparatus constructedaccording to my invention;

Figure 2 is a vertical transverse section of the same.

Figure 3 is a side view of the same on a reduced scale, showing the manner of removing the can after the soldering-operation is performed. I

Figurci; is adetached section of a portion of the same on an enlarged scale.

Similar letters of reference indicate corresponding parts in all the figures'.

This invention is designed more particularly for use in making tin fruit-canspbut it may also rbe employed to advantage in the manufacture of other cylindrical vessels of suoli material, and its object is to enable the operation of soldering the-joints of such tinwareV to be performed with much greater convenience and economy of timethan is practicable by the ordinary method of soldering.

The invention consists in a tubular holder, furnished, near one end, with an annular clasping-lip, in such manner that the can `may be readily secured upon the said holder, and held in such position that its joints may be soldered with very great facility.

The invention further consists in the combination, with the aforesaid holder, of a knob or equivalent device, whereby the easy removal of the ni`shed or soldered can or article from the holder is secured.

To enable others to understand the nature and construction of my invention, I will proceed to describe it with reference to the drawings. I

A represents a cylindrical shell, which may be made of stiff sheet metal, and which is made somewhat-for instance, about an inch-longer than the cauur vessel to be soldered; and secured around one end of this shell is an annular sheet-metal stra-p, B, placed preferably upon an intermediate band, a', whieh'keeps it at a short distance from the shell A, the innermost edge, a, of'which is made iiaring outward, the said edge constituting a lip,tlaring from the surface of the shell A, as shown more clearly in g. 2. Secured in that end of the shell A at which ,the strap B is situated isv a strong transverse bar, Z1, to the outer side of which is attached a knob, C, the purpose of which will be herein presently set forth. g n

In using the apparatus, the sheet-metal blank from which the cylindrical body of the can or vessel is to be formed, having been first bent into proper cylindrical shape, is placed around the shell A, with what is designed for the upper edge of the can'pushed underneath the lip, a, of the said shell, and with its longitudinal edges lapping past each other to any desired degree. The bottom4 of the can is then tted upon the outer or lower end of the body of the can, the position ofthe said body and bottom of the can upon the apparatus .being shown more clearly in the red' outline of g. 2. By this means the upper edge of the body is held snugly in position by the lip a surrounding the same, while the lower edge is correspondingly retained in place by the lanch of the bottom placed thereon, as just mentioned. The partsrof the can being thus secured in position, the joints are soldered by the usualor any suitable means or appliances, which being donc, the knob C is placed betweenY the prongs of a forked or bifureated tool, b, fixed to a suitable support, as shown in red outline in iig. 3, and the can, being grasped by the hands, as represented in the said ligure, is then withdrawn from the'apparatus. .lne apparatus, by -thus serving to hold the body and bottom of the can in position while the joints thereof are being soldered, docs away with the necessity of the means ordinarily employed as prerequisites of such solderingoperation.

The shell may be made slightly tapering toward that end thereof opposite the lip a, if desired, to facilitate the detachment of the soldered or finished can or article therefrom.

I I a`m aware that cylinders provided with a lip of about half an inen wide to bite on the lap of the seam to be soldered have heretofore been used; but these have proved of little value where perfect uniformity of size is desired, as the cylinder to bc soldered is aptto bulge away from the former onV the opposite side from said lip or clip; and; in case the material is less tha-n the average thickness. it will notI beheld by it at all. lh l, therefore, I do not claim; butl What I claim as my invention, and desire to secure by Letters Patent, is

1. "The holder, composed of the shell A, furnished with the annular lip (1,' substantially as and for tho purpose herein set forth.

2. The comonaton, with the holder,

purpose specified. Y
