T0 all wlwm it may concern:

Be it known that I, JOHN STEVENS, of Port Byron, in the county of Cayuga and State of New York, have invented. a oertain new and "usefu1 Imprvement in Paper Vessels; and I do hreby.deelare that the following is a full, elear, and exact deseription of the construction and operation of the same, reference being had to the aecompanying drawings, in which- Figaro 1 is a vertical sectioirof a ohamber. vessel, construeted in aocor danoe W1th my 1nvention. Fig. 2 isa seetion of one edge of the rim detaehed. Fig. 3 is a similar view of one edge of the bottom detached. Figs. 4

and 5 are plans, respectively, of the pieoes of paper for formiug the rim and bottom.

M y improvement relates to the eoustruction of paper vessels, such as ohamber-p0ts, &c., whieh require a projeetng rim or flange at the top, and a closed bottom. The invention cousists, first, in the oombination, with the cylinder or body of the vessel, of a rm formed separately and applied to the body by fitting in a groeve or ofl'set formed in the upper end of thebody, so asto present a flash surfa ee on the inside; and, seeond, in eombining with the said body a separate bottom orbase,

made of angular form, with skived edgesto make.a flush joint, and 'seoured on the under side by oement applied in the groove between the bottom a'ndthe edge of the body, al1 as hereinafter deseribed.

In tledrawings, A represents the cylinder or body of the-vessel, whieh is madeof straw' to receive the Iower flange of the rim, as hereinafter described. IJB is the rim. It consists of two right-angle'd or nearly right-alk glad flanges, .b 0, the first of\=whieh is. verti inside,whil the last is horizontal and may, if desired, be slightly convex in eross-seetion,so as to form an easy support for any body restin g thereon, and may he of any desired pro- 3 jee-tien. This rim is formed from rims of paper d 41, (Fi g. 4,)Whih are slitted part way through from the inside, as shown at e, the

-s1itted edges being that part whieh turns down ro form the vertioal flange b,ihile the unbroken outer edge h lies flat, te form the horizontal flauge 0. These pieces of paper are pasted or oemented together, one overanother,till the proper thiekness is attained, and the whole isthen pressed to the requisite form in a die. The rim thus formed is de mented in plaoe in the groove 01 offset a. 0 is the base er bottom of the vessel. The eentra1 portion f is preferably made round or arehing upward, while the outer edges are turned up to form the flanges g g, which stand slghtly angular tb the body. of the vessel,

and rest at their upper edges aga-iust the inner periphery of the vessel. These edges upon the outer side, are skived 01 dressed ofl, so that the junetionbetween the said edgesand the sides of the vessel will be flush o;;nearly imperoeptible, and will present nqpmieetijon -whenthe interior is painted. spacek,is

This bottom is also formedfrom disks of paper l l, Fig. 5, w hich 1o .form the desix ed thicknss,g and,then pressed tothe desiiedsh'ape. in -a die, 01. they may be placedon a form and' pa)stdtogether, one after another, to give the desired shape,
