The 'Schedule referred no ln these Letters Istcnt und making part of the time.

' Drox, and T. B. ru'rrrnnunr, of Pittsburg, inthe county of Allegheny,laud .State of Pennsylvania, haveproduced a new Manufacture of Hollow Glass-Ware in bas-freliqf, for which Letters Patent No. 35,429 were issued to them on the 3d day of June, 1862, and that the entire interest of said JAMES REDDICK 4in said invention has been assigned tous, as will appear by reference to the records of the United States Patent Oice, liber Xl", page '300, of Transfers of Patents; `and we do hereby declare that'the'following is a full, clear, and exact description oi' that part of our invention'which is embraced inthis division, marked A,

reference being had te Lthe accompanying drawings, makinga part of this specification, in which- Figures 1 and 2 show au elevation and horizontal section of a specimen .of the new manufacture.

Figures 3, 4, and 5, show means adapted for pro# du'cing-said specimen of' the new manuiitcture.

The same letters of reference in the diiierentigures indicate corresponding parts.

Under this patent the nature of our invention does not consist either' in the met-hed or the means for'producing hollow glass-ware in bas-relief, as this waspatentcd to us ou the 4th day of March, 1862; but it consists in the new manufacture itself, to wit, hollow.

`glass articles, with open illuminated bas-'relief work,

as herein described. j

To enable others skilled in ,the art to .produce our new manufacture, we will proceed to describe such means nnd methods as we have found practically useful in its production.

In reducing a lamp-bowl, or peg,. with illuminated ts-relief work on/its surface, as illustrated in digs. 1 and 2,9. base-plate, A, withaI hemispherical, conical, or other desiredformof core on its top, is placed in a glass-manufacturers press, as is usual in making ordinary articles 'of glasswaie.

Around and over this core a lask, or mould, B, oi` the form shown, is fitted sothatjspaces exist between the cor'e and the mould, at those points where illumiu nated bas-'relief w'ork is to be moulded solid.

This mould has the design of vthe desired ornamental bas-relief work wrought in it, as shown in tlg. 4, at a d. The coreissmooth or plain ou its surface.

The plunger O, with the follower of the press, is

i now ,djns'd-for being lowered into the cylindrical chamber D, of the flask B, and `just before it is de pressed melted glass of red color, or other illuminated v color, is put into the chamber D, and allowed to flow aroundl the core, by thesmall passage E, and imme diately thereafter the plunger 0 is pressed down upon the lglass,'and all remaining fluid glass forced outoi the chamber D into thefspaces between the 'core and tho flask, in a. manner togive a s'olid formation to the skeletonbas-relr'ef work The dotted lines show how the plungerdescendsinto the chamber D, and the position that the followerI occupies wheu't'has fully descended.

The next step is to-irivert the mould, with bas-'relief work, plunger, and follower in it, as shown in Iig. 5', leaving the base-plate and core in. their phwes.-

This being done, a two-part desk, G, is fitted ontop l' of the .inverted mould, asshown in iig. 5.

The two-part ilask has a hole, b, in its top, and has:V n

a hinge-joint, on which it opens and closes.

The blower now gathers sufficient flint, or white glass on the end oi' his blow-pipe, and forms it into suitable shape tu blow a lamp-howl, or pegl This ready, thc das): G is opened, and the prepared lump of glass is placed down on the inside of the illuminated skeleton bas-relief work. y

The ilask G having been closed, the blower blows through the orifice b, und, out of the 'lump of glass which was laid on the illuminated bus-relief Work, a

fiiutor other white glass l:|.mp-ho\\l,or peg, H, is. produced, as shown in iig. 5, and figs. 1 and 2, the illuminated workv I standing in bas-rv1ief on the out side oi' thc howl, and, by its brilliant color, in contrast with the light `glass, produces a very handsome and showy effect.

V Instead of blowingthe lower half of the' flint, or A white-glass portion ot the bowl, or peg, the btw-relief work can be produced in the manner described and shown, andthe mould reversed, 'and melted glass put into the mould and pressed by a plunger upon the inside surface oi' the bas-relief work, and the upper portion finished by blowing in the flask G, or iu the old way by treating and bending over with shears or ordinary tools.

li' we want to make a goblet, we pressthe ba-sfrelef work as before described, reverse the mould, and then press the flint, or white glass-in the bas-relief work.

As the forms and sizes of the articles vary, so als must the moulds be adapted thereto.

We have described and shown particularly but one style of article 'and bas-freliqf work, but it is obvious 1 that 'the new rnanuietnre can be extended'to a great variety of articles by simply making changes in the Having described all that part ofourinve'ntion which relates to division A, l

What we claim as new, und desire to secure by Letters Patent, isf- A new manufacture, consisting of blown glass-Ware, 'with illuminated pressed reliefwork on its surface, substantially as .lescribcd,``
