TAYLOR UBIL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALF HIS RIGHT TO THOMAS R. BROWN, OF SAME'PLAOE.

IMPROVEMENT IN MOUTH-PIECES AND LIDS FOR GAS-RETORTS.

speeincation forming part of Letters Patent No. lease/4i, dated July 1o, 1877; appiieation sied June 5, 1877. 1

To all whom it may concern:

Be it known that I, TAYLOR UBIL, of the city and county of Philadelphia,'in the State of Pennsylvania, have invented certain new and useful Improvements in Mouth-Pieces and Lids for Gas-Retorts, of which the following is a specification:

The objects of my invention are to provide suitable means for eecting an air and gas tight joint between a retort mouth-piece and its lid; and, further, to reduce the damage resultant from breakage of the lugs or supports of the lid and fastening by an improved means of connecting the same to the mouth-piece.

To these ends my improvements consist, first, in the combination of a retort mouth-piece, having a groove orrecess extending around its outer face, with a lid having a groove or recess of symmetrical outline to that of the mouth-piece, and containing a yielding or elastic packing, which projects above its face, and

, tits into the groove of the mouth-piece, being compressed therein by the screw and cotterbar or other fastening, by which the lid is pressed up toits position when closing the mouth-piece.

My improvements consist, secondly, in the combination of a retort mouth-piece, having a recessed side flange, with a removable hingepiece fitting into the recess of said ange, and secured thereto so as to be readily renewed in the event of breakage, without affecting the position or the other connections of the mouth-piece.

In the practice of gas-engineering, various expedients have been from time to time proposed and practiced for the purpose of preventing the entrance of air and escape of gas between retort mouth-pieces and their lids. Various materials in the nature of` luting have been employed for this purpose, and in some instances copper or-lead has been inserted in grooves in the mouth-piece, and compressed therein `by a projecting rib or tongue on the lid. Fusible alloy has also been similarly employed.

- An objectionable feature in such application has, however, existed in the fact that the packing is to a greater or less degree forced out of its groove by the entering rib upon the application of pressure by the fastening device, and thereby exposed to the destructive effect of the direct action of heat.

In the use of my improvement the projecting portion of the packing material is covered and protected by a receiving-groove, into which it is compressed, and a tight joint is thereby insured without the necessity of frequent renewals.

Retort mouthpieces are, further, ordinarily constructed with the lugs or bearing-pieces, to which the lid andfastenin g are to be hinged, cast upon them, and in such case the breakage of a lug, which frequently occurs in the operations of drawing or charging, entails the removal and loss of the entire mouth-piece. My improvement enables a broken lug to be readily and speedily replaced without the removal of or detriment to the mouth-piece Aor retort, or their connections.

In the accompanying drawings, Figure 1 is a front or face view of a retort-mouth embodying my improvements; Fig. 2, a vertical central section of the same; Fig. 3, a horizontal half-section at the line l l of Fig. l; Fig. 4, a vertical section through the side iange and hinge-piece; Fig. 5,`a view, in perspective, of l the hinge-piece detached; and Fig. 6, a section `on an enlarged scale, showingwamodication in the form of one of the packing-grooves.

To carry out my invention, I form upon the front or face of the retort mouth-piece A a groove or recess, a, extending entirely around said face, and being, preferably, of a curved or segmental cross-section, and upon the in side of the'lid A1 a groove, al, symmetrical in outline, or corresponding with the groove a, but dovetailed or undercut on one or both sides, the better to retainl the packing b, with which it is filled. The packing may consist4 amants: i @rr-ron.

of pressure yby the 'cotiser-bar G and 1 screw i0',

, or by any other fastening device which may be employed, the projecting portion of the pack- A erable, is notfessential, and in Fig. 6 a kidney form or triple-curve section of the groove is shown. Y

It will be further obvious that the relative positions of the retaining and receiving grooves might be reversed, it' desired, without departing from the spirit of my invention, the prominent feature of which consists in providing a cover or'receptacle for the projecting portion 0f the packing.

A side flange, A2, is formed uponthe mouthpiece A, within which flange is formed a recess, az, to receive a removable hinge-piece, D, which fits neatly therein, and is secured by a bolt or bolts, d. The base of the hingepiece D is of sufficient area to give firmness to the union made between it and the recessed flange, this feature causing this part of my inupon which the cotter-bar-Cand lid Al are pivoted.

In case of breakage of either of the projecting `lugs, the hinge-piece can be readily removed, and another substituted at-tritling cost,

without affecting the position of the mouth- .piece and stand-pipe.

I am aware that joints "have been made in gas-retort mouth-pieces by the compression of a yieldingpaeking betweeu'a 4,recess and an entering rib or projection, asin the patents of .W. H. St. John, No. 16,075, November 11, 1856,

and N. Aubin, No. 17,068, April 2,1, 1857. I do not, therefore, broadly claim" the -use of packing in combination with grooved surfaces ina joint.

I claim as my invention and desire to secure by Letters Patent- 1. Thec'ombination, witha gas-retort mouthpiece having la groove lor `recessaround its outer face, of a lidhaving a groove of corresponding outline lilled with 'yielding `o'"f'e1as tic packing, which projects and 'tits into the grooveof the mouth-piece when the lid zis closed thereon, substantially as seti'orth.

2. The combinationof .a retort'xnouth-pi'ece, having a recessed sid'eiangeI and a gremovable hingepiece,'with a plate 'fitting into the recess of said ilange, and fbolted thereto, sub-l stantially as set forth.
