PROCESS OF MAKING MU FFLES OR RETORTS.

SPECIFICATION forming part oi Letters Patent No 357,079, dated July 26, 1887.

Application filed January 29, 1887. Serial No. 225,858. (No model.) Patented in Germany February 8, 1880, No. 11.676, and February 11, 182, No. 19,337, and in Austria-Hungary February 1'2, 1881. No. 39,314 and No. 4,l14.

To all whom it may concern:

Be it known that I, CARL WERNIOKE, a resident of Konigshiitte, Prussia, in the Empire of Germany,- have invented an Improved Process of and Apparatus for Producing Muffles or Retorts for Spelter-Furnaces and the Like, (for which I have received Letters Patentin Germany, No. 11,676, dated February 8, 1880;) and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same, reference being made to the accompanying drawings,.iu which- Figure l'is a side view of my improved apparatus for making muflies or retorts. Fig. 2 is an edge view of the same. Fig. 3. is a top view of the same. Fig. 4 is a horizontal sec Fig. 5 is a vertical longitudinal section of the same. Fig. 6 is a vertical cross-section of the same. Fig. 7 is a vertical longitudinal section of the same, showing the parts in position after the muffle or retort has been completed.

This invention relates to a new process of stamping into shape muffles, retorts, or the like, instead of molding them in the usual form heretofore practiced; and it consists of the new apparatus, hereinafter described, for permitting the production of such muffles, retorts, and the like in the inverted position by the process of stamping, and also in the process itself.

In the accompanying drawings, theletter A represents the base of the apparatus, the same consisting of two or more planks properly planed or smoothed and bolted together by bolts a. This base A supports the upright jacket B of the apparatus, which jacket, as appears from Fig. 4 of the drawings, consists of three (more or less) upright parts properly fitted together. These three (more or less) parts of the jacket B are crowded against one another in the desired relation by an outer framing, O. This framing (3 consists of series of beams b,that are placed against the faces of the jacket, and of bolts d, that connect said beams, and of cross-bars e, that traverse said beams, and of wedges f, that are inserted between said bolts dand cross-bars e, for the purpose of properly tightening the connections.

l Thesections of framingO may be supported, if desired, on brackets 9, that project from the jacket B, as shown in Fig. 2. The core D of the apparatus, which in cross section has the form, and which is closed on top, as at h in Figs. 5and 7, is suspended by upright bolts 1 from a strap, 9', that is placed across the top of thejacket B, the bolts 72 extending through holes in the top h of the core. A spacing block or washer, k, with tpreferably sloping sides, as in Fig. 6, is interposed between the strap j and the top h of the core, the boltsi passing through this washer, as shown. When thus suspended by the bolts 73, the core D has its lower end a short distance above the top of thebase A, as is clearly shown in Figs. 5 and 6, the base being properly recessed to receive in the recess the lower portion of said core.

A small frame, I, is interposed between the lower end of the jacket and the part of the core which is nearest the same, as is also clearly shown in-Figs. 5 and 6.

In order to prevent the elevation of the jacket while stamping the muffle or retort into place between the jacket and the core, I prefer to unite one of the sections of the framin O by jointed rods E (see Fig. 5) with the base A, these jointed rods having loops m for receiving and retaining wedges n, as shown.

The parts being in the position shown in Figs. 5 and 6, I now proceed to fill the space between the core and the jacket with the matter for the retort or muffle, which matter rests on the framing Z, and is stamped or rammed down tightly by suitable means until about two-thirds of the height of the muffle or retort has been thus introduced. After this Iremove the bolts t, the strap j, and the washer k, and I thenforce the core D down until its lower end reaches contact with the base A, as in Fig. 7. I then place upon the holes, which exist in the top of the core D for the reception of the bolts t, small tin or zinc plates 0, and proceed to ram into place the remainder of the substance necessary for completing the said walls and the closed end of the muflie. The

dotted structure F (shown in Fig. 7) represents the completed muflie, and it will be seen that the end or bottom of the mufiFle is produced above the top of the core. The driving down form shown in Fig. 4, or any other proper while withdrawing the core.

of the. core from the position shown in Fig. 6 to the position shown in Fig. 7 is facilitated, because the core is narrower at the uppercnd than at the lower end, and by driving down the core that part of the muffle which has first been rammed into place is loosened and receives additional force from the subsequent ramming in of the remaining portions neces sary for producing the complete muffle. After the niuffle has been thus produced I withdraw the bolts 00 and (1, remove the base and the framing G, withdraw the core, take the jacket apart, and obtain the complete mnflle in proper shape and consistency. The thin plates 0, which were placed over the holes of the top it of the core, will prevent air-suction from disturbing the continuity of the parts of the niuflle \Vhile with- Other articles besides muffles may be produced with this apparatus and according to this process. What I mean by a closed end in this specification is the usual bottom in which there may be one or more small holes.

I claim- 1. The process herein described of making vessels of clay or analogous substance, which vessels are closed at one end and open at the other, the said process consisting in first forcing the material for the open end of the vessel into an annular space around a core and in afterward forcing the material for the closed end of the vessel against and around the end of the core, as specified.

2. The combination of the vertically-mov- 4o able core D, having closed top It, with the bolts 2 strap j, sectional jacket 13, recessed base A, and framing C, substantially as and for the purpose herein shown and described.
