mrscvnnhsr IN arms :03 PUTTING UP amiss.

TO ALL WHOM IT MAY CONCERN Be it known that I, PATRICK HICKEY, oi the city of Philadelphia, and State of Pennsylvania, have invented certain new anduscfullmprorcm ents in Putting in the Heads of Cans designed for holding Alkalies, Paints, and such like substances; and I do hereby declare the following to be a full, clear, and exactdcscriptlon-oi' the same, re'ferenco'being had to the accompanying drawings making a portot' this specification, in which- Figure 1 represents a sect-ion through one of the cons with the bottom set in, and the top-in its condition when ready to-hare the head laid into its place preparatory to its being permanently securod'thsre, as nill be explaiped. i v

Figure 2 represents a similar section through one of the cans after the head is set and fastened in, and

showing tho collar or tool against which the metal is pressed in fastening in the head.

Fig'uro 3 represents a top plan of the czm'with the collar or -tool in place It has been found to be exceedingly dillienlt to make a tin or other sheet-metal can that nould hold alkalies, paints, and such other substances, and in particular tight ehough to-pr eveut the leakage from' destroying the labels on the cans, or staining them, which injures their marketable or salable value, and trastes the con tents. In patting such material into eons the head must lie-left out, so that the-material can be readily put in; when the can is filled, it must be kept in an upright position, andheld very firmly orsteadily whilst the headis being fastened in, to prevent the contents from being shaken out or spilled. To solder in the headsis expensire and troirblesome, and must be dono'at the works wheropacked;

My'invoution has for its object not only the facilitating of the operation of putting in the heads of can; that are filled with alkali or othcreuchdike penetrative material, but to cheapon, the operation, and make a better joint than has heretofore been done, and by which plan I can dispense with the use of solder.

To enable others skilled in the nrt'to make and use my invention, I will proceed to dcscriboth some with reference to the drawings.

.- The can prefer to make cylindrical, though other forms may be used if found desirablemr for close packs ingin square boxes. The bottom, .A, of the can is set into the body? in the some inannertha't the head is, but before there is anything in the can, and when it can be turned or held in any-manner, and is comparatively a simple operation.- The top of the body B isswagcd out into the form shown in fig. 1, that is, with a bevelled shoulder, 2, and a concentric flange, 3, which shoulder and flange enlarge the cylinder or hody-sulficiently to allow tholicad C to be laid into its place. 'lhis headC, like the bottom, A, may be stamped out n'ith sunken and raised portions or corrugations, to give it stiffness, and has upon it a flaring flange, 4, that willlioagiii'nst sndon the inside of. tho bevelled shoulder 2 of the body 13, as seen iuifig. 1.

I When the'can is filled with the material it is to hold and contain, tho'head G is laid into'its place, and then a steel or othermetal collar, 1), is put around the body B'nnd against the bevelled shoulder 2, the edge of said collar being chamfcrcd oil to snugly fit against said borollcd shoulder-,and'whilst the can is in its upright position and the collar clasped around it, the flange 3 is turned and set down against the flange 4 of the head 0, which lashes a perfectly tight joint, sufiicic'ntly so .nithout soldering to hold the most-volatile or pen'etrativo substances. The collar D, to facilitate its placing and removal, is hinged at a, fig. 8, and diametrically oppo site the hingcthcrc is a tong'uc and-mortise, lap, or clasp-joint, b, for holding the ends of the collar together when in position for serving as an anvil to set tho joint against: When the head 0 is being put in, the can may remsin stationary upon the bench, table, or standl is, thus turning the body of the ean'orer upon .he heads, the joint or line of union is'such that it there should be even thefleast escape of. vapor or gas from the .inside it would not reach thelabol n'hich'is on the body, and hence not destroy or stain it. And whilst no pressure that, could occur inside of the can could force out the heads, yet when access to the contents of the can is desired, by strl'ltingfupou-t-ho inside of the hangs, aud drivirtgit outward, the head may he rosdilyremovod. v

, 'Haylng' thus fully deacribodmy invention, what Iclnim therein as new, and desire to secure by Letterm- Pstent, is- V Q Setting the heads mto alkali, point, or other similar cons, by-means of the flanges 2, 8, hand a collar- 13 encircling the body, so that said head's may be permanently andtightly set into the body whilst full. and sitting in an upright position, substantially as described, and for the par-pose set forth fATkrcK H'ICKEI Witnesses W.
