JOHN r. LEWIS, or NORTH BnAnnocK, AND Jenn W. KAGARISE, or wrLKINsBURG,-

rENNsYLvANIA. l .Y

, BUcKs'rAY.

T all 'w zom t 'may concern Y Be it known that we, JoHNF. Lnwis and JOHN l/V. Keeaiusn, citizens of the United States, and residents, respectively, of North Braddock and lWillrinsburg, both in the county of Allegheny andj Stat-e ofv Pennsyl- Vania, have invented vcertain new and useful linprove'inents in lduclrstaya'ofA which the following is a specification.

@ur invention relates to the construction of furnaces and has particular reference to a novel buclrstay for use in connection with open hearth furnaces.

One object of our invention is to provide an improved form of vbuclrstay composed of a substantially lrectangular rolled or forged lsteel slab having a novel water passageway therein. p

Another object is to provide a buclrstay which may be more easily and cheaply manufactured than those heretofore used. Y

Heretofore buclrstays of this class have had an aperture drilled throughout their length to provide a p'assagewayfor the cooling water. rThe drilling of these buclrstays requires a great amount of labor' and'is costly. i

To provide a buclrstay of reasonable cost and of great durability, we manufacture it of a rolled or forgedsteel slab. of the required length. This slab, usually rectangular in cross section, is then machined. or forged to form an open recess along one of its narrow faces, and closing plate is into the passageway and tapped to receive the circulation pipes.

The construction of our improved buckstays will be fully understood by reference to the accompanying drawings,in which :-v

Figure 1 is an elevation of part of an open hearth furnace showing buckstays embodying our invention.

Figure 2 is a sectional plan through part of an open hearth furnace showing buckstays embodying our invention, in position thereon.

Figure 3 is a sectional. elevation through the furnace of Figure 1 onthe line III-III of Figure 1. I

Figure 4 is a side elevation of one of the buckstays.

Fig. 5 is a front elevation of one of the buckstays.

Specicaton of Letters Patent. :Fatal-@Qd Aug. F22 1922( lApplication filed May 9, 1921. Serial No. 467.824.

Figure 6 is a cross section on VI-VI of Figure 4L. l

Figure 7 is a similar cross section on the line VI-VI of Figure 4l showi g the weldingmetal applied'to hold the cover plate in position. Referring more particularly to the drawings, the the furnace which is of usual construction. Extending along the furnace` wall 2 is a se ries of vertical buckstays 3 rsecured to the girder 4: along the tops thereof..V

rllhe usual doors 5 are mounted to reuprocate vertically in the door frames 6 which are secured to the buclrstays 3. i

the line numeral 2 designates they wall ofl` The buckstays constructed according to offset causing the open side of the recess to be of greater dimensions than the main portion thereof and forming shoulders `11, the side walls of which are beveled outwardly as at 12. l l

A cover plate 13 is mounted on the shoulders 11 and is of such size as to completely close the open side of the recess 10. The edges of the cover plate 13 are beveled as at 14 to co-operate with the beveled portion 12 of the recess walls and forni a V-Shaped retaining pocket 15 for the reception of welding met-al 15a used to weld the plate in position. It will readily be understood that by welding` the plate 13 in position a permanent, tight and practically integral construction is obtained.

An inlet port 16 is formed through the end of the stay and communicates with the recess 10 and has its outer end countervbored and threaded to form a seat 17 for plate 13 adjacent the upper end of the recess l and an outletpipe 2l' is *screwed therein. A 'second outlet or` drain and cleanout.r ort 22 is formed through the outer face of t e stay and into therecess adja cent the f bottom thereof, and is provided `With a screw plug- 23 or` other` removable j closure adapted to be opened When itis desiredto flooder clean out the recess. t

l Themany advantages of af buckstay conf structed as shown VWill `be readily appreciated by those skilled in the art. i The re-` cess lO may be formed uichly and cheaply, and may ,be so shape that the greatest amount of cooling yarea may be had.

` While'we have shown one particular embodiment of; our invention, it will ybe .un- `derstood.,that We do not Wish to be limited "tothe =exact construction shown .since varil se ous modifications may bemade Without de parting from the Spirit :of our invention as defined inthe appended claims.
