SAMUEL A. THOMAS, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN MOUTH-PIECE LIDS FOR GAS-RETORTS.
Specification forming part of Letters Patent N0. 16] ,716, dated April 6, 1875 application filed March 15, 1875.
To all whom it may concern:
Be it known that I, SAuUEL A. THOMAS, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Mouth- Piece Lids for Gas-Retorts, of which the following is a specification:
The object of my invention is to provide a lid or cover for gas-retorts which will be selfsealing-that is to say, gas-tight without the necessity of luting, and which will accommodate itself at all points to its bearing upon the mouth-piece; to which ends my improvement consists in providing the lid with a flexible rim or flange, as hereinafter more fully set forth.
In the accompanying drawings, Figure 1 is a'perspective section of a retort mouth-piece and lid embodying my improvement 5 Fig. 2, a plan or top View of a portion of the same; and Fig. 3, a section, showing another application of my invention.
The mouth piece A is, in this instance, shown as constructed for application to a D- shaped retort, to which it is attached by bolts passing through its rear flange, A. The front or opening of the mouth-piece is, by preference, provided with a conical bearing-surface, a, extending all around its periphery. The lid B is of similar outline to the opening of the mouth-piece, and is provided with a rim, flange, or lip, I), which fits over the bearing-surface a of the mouth-piece, and is formed of plate-iron,
or any other suitable material of a flexible character.
The lid may be held in position by the hinged bolts 0 and clamping nuts 0, as shown, or by the ordinary transverse bar and central screw, or any other form of fastening preferred.
The rim 1), it will be observed, has a narrow bearing upon and entirely around the bearingsurface a, and, by reason of its flexibility, adjusts itself accurately and closely thereto, and enables a gas-tight joint to be made without luting or cementing.
In the modification shown in Fig. 3, the bearing-surface a is formed upon a flange extending around the periphery of the mouthpiece, and the flexible rim 1) bears upon packing a, which it presses up to the face of the flange.
I am aware that inclined or conical bearingsurfaces have been proposed upon the mouthpieces of retorts, in connection with lids havin g correspondingly-inclined faces, and do not desire to claim such device.
I claim as my invention As a new article of manufacture, a mouthpiece lid for retorts provided with a flexible rim or flange, substantially as set forth.
