To all' whom it may concern.' j

Be it known that I, Jer-IN THOMPSON, a citizen of the United States, residing in Little Falls, Passaic county, and Stateof New Jersey, have invented certainnew :and useful Improvements in Means for Bracing the IValls of Furnaces; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, ref? erence being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this speciication. Y

In the boiling of oil, as in the refining thereof, the receptacles or boilers for the oil are usually supported on masonry partitions in rows, the said partitions forming the sides of the several furnaces. The great heat to which it is necessary to subject t-he oil occasions constant injury to the said partitions, manifesting itself usually in a bulging of the same, and necessitates frequent repairs thereto. Aside from the con` siderable expense which must therefore now be laid out to keep the partitions in order, it is a matter of extreme difficulty to repair `them wit-h the expedition required by the circumstance that the oil in the boiler `at the time the repairs are being made must not be allowed to cool below a certain temperature, necessitating, as this does, that the repairs be therefore effected in a condition of intense heat radiated from the hot oil into the space of the furnace.

The object of this invention, therefore, is to provide means for reinforcing the walls `in such a way as to keep them in order for very considerably longer periods than is now the case; and this object I have accomplished in and by the means shown in one adaptation thereof, by way of illustration, in the accompanying drawings and hereinafter described in detail.

In these drawings, Figure 1 is a front elevation, partly in section, illustrating my invention; Fig. 2 is a longitudinal sectional view taken substantiallyY centrally of one of the units appearing in Fig. l; Figs. 3 and i are horizontal sectional views taken on lines .fn-.r and y-y, respectively, of Fig. 2; and Fig. 5 is a detail view, partly in section.

The partition walls to be reinforced are shown at a, the same representing the sides of the furnaces arranged side by side, each such furnace having' a back wall (not shown), a boiler-front or frontwall b provided with lire, ash-pit and clean-out doors C, Z and e, and` a grate f. g designates the boilers in which the oil is heated, the same being supported in the usual manner side by side on the walls a. j

On the foundation between each two of the walls a are arranged the parallel sills z' suitably distanced from each other and each extending crosswise of the space between said walls and fitting between the same; each of these sills is preferably formed of metal and has on its under side a central longitudinal strengthening rib j. The ends of each sill are furthermore rounded out or recessed, as at 7c. Atthe ends of each sill and stepped on the foundation are the uprights or columns Z, each being tubular, having both ends closed, provided with'an inwardly projecting foot m which underlies the adjoining end of the sill (whose rib is cut away at that point), 'whichr rests upon it, and having its relatively outer face n Hat and bearing squarely against the face of the adjoining wall a and its relatively inner face o semi-cylindrical or convex in plan. The sills and up rights or columns being in place as described a floor of cement p may belaid.

At the upper ends of the uprights or columns of each pair thereof are formed the internally threaded bosses g, facing each other, and into these are screwed the ends of a tubular brace r formed of two sections of pipe s having right (or left) hand threads on their adjoining ends which receive the coupling t for adjusting the brace longitudinally. In the assembling, the coupling is primarily on one pipe-section, and after the two sections have been alined and turned in the bosses tobring them as close together as possible the coupling is turned until it couples the sections, whereupon a lock-nut t is jammed against it to secure it where adjusted.

The several uprights are provided with internally threaded bosses u at their lower front sides; all, except the rear upright (the right hand upright in Fig. 2), are also provided with similar bosses fr at their upper rear sides. Connecting the upper rear boss with the lower front boss of each two adjoining upriglits on the same side of the furnace is an adjustable pipe fw, the connec tion between the ends of which and the bosses may be afforded by the nipples as and elbows y; each pipe w comprises two pipe sections to having their threaded adjoining ends receiving a coupling e and a lock-nut e similar to coupling t and lock nut t. If, now, water or other cooling fluid be admitted to the front lower boss of one of the front uprights, it may circulate through the tubular bracing structure thus formed, passing alternately up through the uprights and down through the pipes w at one side of the furnace (a part of it going across to the upriglits at the other side of the furnace through the braces r) and down through the uprights and up through the pipes tu at the other side of the furnace (the side appearing in Fig. 2), finally discharging at the front lower boss of the other front upright. In this way the bracing structure is protected from the warping and other injurious influences of the heat ofthe furnace.

The cooling medium is preferably introduced into the bracing structure under pressure, and it is desirable to connect the front lower bosses u of the front adjoining upriglits of two adjacent furnaces by piping 2 whereby the several bracing structures of the series of furnaces Will form a single system through which the cooling medium circulates from one end of the series of furnaces to the other.

I find it desirable to provide means for preventing the cooling medium short-circuiting and so failing to flow through one or more of the braces r relatively remote from the inlet and outlet of each bracing structure, whereby that part of the latter would be unprotected by the cooling medium. To' this end in the discharge ends of some or all of the braces (excepting the rearmost one), that is, in the ends adjoining the upriglits appearing in Fig. 2, reducing plugs 3 may be screwed, the ports through which, designated 4E, are graduated in size, the smaller port being in the plug for the front brace. The size of these ports may be such as the circumstances, pressure, heat in the furnaces, etc., may require.

The object in rounding the exposed face of each upright is to facilitate the handling of the firing tools of the furnace attendant; the opposite faces being flat and broad offer good support for the walls a.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination, with opposite walls of a furnace, of a tubular bracing structure therefor having an inlet and an outlet for a circulating cooling medium and comprising hollow supporting members engaging said walls Y and a tubular brace securing said members in fixed relation to each other, the interior of the brace communicating with the interior of each member, substantially as described.

2. The combination, with opposite Walls of a furnace, of a tubular bracing structure therefor comprising hollow supporting members engaging said walls and respectively having an inlet and an outlet and a tubular brace securing said members in fixed relation to each other, the interior of the brace communicating with the interior of each member, substantially as described.

3. The combination, with opposite walls of a furnace, of a tubular bracing structure therefor having an inlet and an outlet for a circulating cooling medium and comprising tubular upriglits bearing against the adjoining faces of said walls and a tubular brace securing said upriglits in fixed relation to each other, the interior of said brace communicating with the interior of each upright, substantially as described. y

4l. The combination, with opposite Walls of a furnace, of a tubular bracing structure therefor having an inlet and an outlet for a circulating cooling medium and comprising two hollow supporting members respectively engaging said walls and means for conducting the cooling medium through said members, substantially as described.

5. .The combination, with opposite walls of a furnace, of a tubular bracing structure therefor having an inlet and an outlet for a circulating cooling medium and comprising two series of hollow members, one series en gaging one wall and the other the other wall, and means for conducting the cooling medium through each series of members, substantially as described.

6. The combination, withA opposite walls of a furnace, of a tubular bracing structure therefor having an inlet and an outlet for a circulating cooling medium and comprising two series of hollow members, one series engaging. one wall and the other the other wall, means for conducting the cooling medium through each series of members, and tubular braces connecting the members of one series with those of the other and each having the interior thereof communicating with the Vinterior of each member, substan- Y tially as described.

7. The combination, with opposite walls of a furnace, of a tubular bracing structure therefor comprising two sets 0f hollow supporting members respectively engaging said walls and means for conducting a cooling medium through the members of each set in succession, substantially as described.

8. The combination, with opposite walls of a furnace, of a tubular bracing structure therefor comprising two sets of hollow supporting members respectively engaging said walls and means for conducting a cooling engaging said Walls and each having a foot 15 projecting toward the other, a sill interposed between said uprights and resting on each foot thereof, and a brace disposed above the sill and connecting said uprights,

substantially as described. 20 In testimony7 that I claim the foregoing,

I have hereunto set my hand this 10th day of November, 1910.
