GLASS-W131i MANTLE AND CLAMP THEREFOR.

Patented Mar. 7, 191%.

Application filed August 5, 1915. Serial No. 43,812.

To all whom it may concern Be it known that l, SETH B. linnsrraw, a citizen of the United States, and a resident of Charleston, in the county of Kauawha and State of West Virginia, have in vented certain new and useful improvements in Glass-Well Mantles and Clamps Therefor, of which the following is a specification.

My present invention relates generally to glass furnaces, and more particularly to the wells or drawing chambers thereof as used a in the drawing of vertical cylinders of glass in the manufacture of window glass, my object being to form tne glass well or drawing chamber by means of vertically disposed fire clay mantles having interengaging portions and to provide in connection with the furnace bindings, clamps engageable with the series of fire clay mantles so disposed in order to hold the same firmly together and prevent accidental displacement.

In the accompanying drawings have shown an arrangement whereby these objects may be well and effectively carried out, as will be better understood from the following description in which reference is made to this drawing, forming a part of this specification, and in which- Figure 1 is a plan View of a well or draw ing chamber constituting part of a glass furnace, and constructed in accordance with my invention. Fig. 2 is a plan of one of my improved clamps, two of which are utilized in connection with each well or drawing chamber as illustrated in Fig. 1, and Fig. 3 is a detail side view of the body plate of the clamp.

Referring now to these figures, and more particularly to Fig. 1, it will be seen that the well or drawing chamber indicated generally at A. is constituted by a surrounding series of vertically disposed fire clay mantles B, the upper ends of which extend above the roof of the furnace, and are usually supported by vertically extending bolts and the like clearly indicated at B in Fig. l, the upper ends of which bolts are suitably united to the superstructure of the furnace in a manner of the present invention and which when used still permits of the relative movement of the mantles B and accidental displacement thereof. It is for this purpose that I provide the mantles with relatively engagwhich forms no part ing ribsand recesses along their vertical slde contacting edges as shown in Fig. 1 at B, and further provide clamps in engagement with the outer mantles of the series as indicated at C and C in Fig. 1, 0

each of these clamps being adapted for co- 1 operation with a buckstave D and D formmg part of the furnace binding and conslsting of vertically disposed channel beams in opposed pairs at opposite sides of the as drawing chamber, the beams facing outwardly as shown. Each of the clamps C, C, to this end includes a body plate C one end of which is bent to engage the outer flange of one of the beams of the particular buckstave in connection with which it is to be used, and further provided with an aperture 0 for the reception of an angle bolt E adapted to be secured therethrough in engagement with the outer flange of the other beam of the same buckstave as particularly apparent from an inspection of Fig. 2, the body plate being thus supported in rigid connection with the buckstave with which it is used, to extend at right angles therefrom. Adjacent its opposite end, the body plate G has a threaded opening through which a. pressure screw bar F is mounted, the outer end F of this bar being squared for the reception of a wrench or suitable tool,.and the $5 inner end thereof being adapted to abut the outer mantle B of the series forming the wall of the well or drawing chamber as before described, so as to create a pressure through the several mantles forming this wall for the purpose of thereafter maintaining the same in close contact under pressure,

in order to prevent relative movement and accidental displacement.

Thus by means of the particular arrangement I have"desoribed, and by the use of the particular clamp as illustrated, I am enabled to obviate practically all difficulty now universally present in connection'with the upkeep of the wells or drawing chambers of lass furnaces; to entirely eliminate accidental displacement and shifting of the mantles forming the walls of such wells or chambers, and to reduce to a minimum breakage of the mantles, thereby saving considerable time, labor, and expense in substitutions and repairs.

I claim 1. A clamp for holding fire clay mantles comprising a body plate having means carried thereby at one end for detachable engagement with the outer portion only of a buckstave, and a screw bar threaded through said body plate for adjustment to engage the mantles, as described.

2. A Clamp for holding fire clay mantles comprising a body plate having one bent end and an angle bolt adjacent and cooper- V. F. BLACK, S. RICHMOND
