This invention relates toi'mprovements. in acid.

acid chamber.
Chambers of thistype comprise a.bo.ttompan composed ofilead ,andji'n ,whichthe, acid collects, and a lead chamber. or. casing; suspendedin. a.
suitable framework aboyelthe; pan.. In. some .instances thelower edge, oflthe. side wallor curtain of the chambergis .b'urned't'd the. upper edge of the side wall or upstandofthe pan; and in.
othencases the chamberisssupported with the lower part of the curtain encircled by and spaced from the said ,upstandiand;withitheilower edge of the, curtain below theplane of, the upper edge of-theupstand and elevatedhbovezthe bottom of. the pan. In the latter case the acid in'the pan forms a liquidisealiat theibottommfithe-chamber. In either. case it is customaryto provide.an.ex-- ternal 1 support and reinforcing, backing. for. the said upstand. Conventionallytlielsaid casing,.or lead;chamber is suspendedQin a framework which embracesboth the pan andthecasing as.h erein,- after more specifically set forth.
The present inventiomhas for itsprimary object the provision of an improvedmeans for supporting,
and reinforcing the upstandingwall ofrthersaid pan, said'supporting'means being of a character to afford ready access when necessary to the outer face of said wall for inspection and repair, and particularly to afford access to the critical area at the juncture of the upstanding side wall of the pan and the bottom wall, within which area the pan is most subject to deterioration.
More specifically the invention contemplates a novel supporting structure for the pan upstand composed of a number of sections individually readily detachable so as to uncover the adjoining portion of the pan wall.
The invention further resides in certain novel structural arrangements and details hereinafter described and illustrated in the attached drawings wherein:
Fig. 1 is a fragmentary elevational and partial sectional view showing the lower portion of a chamber made in accordance with the invention;
Fig. 2 is an enlarged fragmentary vertical sectional view showing more clearly the details of the illustrated embodiment of the invention;
Fig. 3 is a section on the line 3-3, Fig. 2;
Fig. 4 is a section on the line 44, Fig. 2, and
Fig. 5 is a view in perspective of one of the elements of the structure.
With reference to the drawings, the pan previously described. is indicated by theirefer-ence unite said uprights. The-lead curtain l.-. 013217118:

The structure asdeseribed; above is conventional and form'svnoepartv of myg invention, excepthasto certainrdetailss described below. 7
The frame memberssd-are, in.the.presentV-in-r stance, T-shaped. in cross -sectionghassbestdllus trated. inFig. 4, andrthe lowerendsmfvtheseisec tions seat upon andarersecured tc'foot platesalza which rest upon and .aresecuredt'o'the: founde tion 2 by-means ofboltstlta Thezwall-or upstand l t-of the pan l restsfflatly agai-nstthesurfaceselii oftheheads [fir-0f the. respectivesframewrnemberstr; In accordance with the invention the said wall I4 is reinforced or backed in the areas intermediate the said members 5 by plates ll of segmental form, best shown in Fig. 5, one of which extends between each adjoining pair of said upright frame members. The plates l'l conform substantially in height to the wall l4 and have at each end an outwardly off-set flange l8 which in assembly overlies the respective side portions of the head l6 of the frame member as best illustrated in Fig. 4. The flanges l8 are apertured at H! for reception of studs 2| which are secured in and. project from the said head portion l6 of the frame member whereby through the medium of associated nuts 22 the said plates may be secured against the outer faces of the said head l6. By reason of the fact that the flanges [8 are off-set forewardly from the body of the plate I! to the required extent, the inner faces 23 of the plates are in effect flush with the faces l5 of the frame members 5 and form with the latter a substantially continuous backing surface for the wall l4. Each of the plates I1 is provided at the top with an outwardly projecting flange 24 and at the bottom with a reinforcing channel 25, the lower flange '26 of this channel seating upon the foundation 2. As best shown in Fig. 2, the wall H extends outwardly over the top of the flange 24 and is secured to the latter by means of bolts 21.
In accordance with the conventional practice in the operation of chambers of this character in the production of sulphuric acid, means is provided, not illustrated, for flowing water downwardly over the curtain of the casing 3. Adjacent to the bottom of the curtain and to the top of the pan l, a trough 3| is provided which is secured to the outer face of the casing and extends completely around the latter. The trough is provided at one or more points in the bottom thereof with discharge ducts 32 through which the ance with conventional practice the pan I is provided in its bottom with one or more dis-charge openings 33 which is normally closed by a suitable stopper 34 at the lower end of a stoppermanipulating rod 35, said rod extending upwardly to-the top of the wall l4 so that it may be available for removal or reinsertion of the stopper 34 as may be required.
It will be apparent that whereas the aforedescribed construction afiords a continuous backing for the wall 14, and an adequate support for said wall, the detachability of the individual plate elements I! provides a ready means for access to the outer surface of the wall for inspection and repair. It is to be noted also that since the plates H extend completely to the bottom of the wall I4 that removal of the plates will afford access to the area at the juncture of this wall with the bottom of the pan where deterioration of the pan structure is most apt to occur.
Attention is directed to the links 9 and the manner in which they are secured in the structure, as illustrated in Figs. 2 and 3. It will be.
has assumed a normal position in the assembly as shown in Fig. 2. The plates 38 thus form normal seats for the retaining nuts 39 on the upper ends of the links and the latter are stressed in alignment with their longitudinal axes.
While the invention has been described and il lustrated in connection with the open or liquid-sealed form of chamber, it is apparent that it is applicable also to the closed" form of chamber, wherein, as set forth, the lower end of the curtain is joined to the upstand of the pan.
I claim:
7 In a sulphuric acid chamber, a pan having an upright side wall, a supporting framework, a lead chamber supported by said framework with the bottom edge thereof within said pan and elevated from the bottom of the latter but below the upper edge of the side Wall, said framework com-' prising an annular series of uprights of T-section embracing said pan and arranged with the head 7 portions of the Ts confronting the upright side wall of the pan and forming flat abutments for the outer face of said wall, and a plate section spanning the space between each adjoining pair of said uprights with theside edges thereof contiguously to the side edges of the said head portions of the uprights so as to providea'continuous flat backing for the said outer face of the wall, said plate sections having at the sides' REFERENCES CITED The following references are of file of this patent:
