The object of the invention is to provide.

a tank of thinsheet metal and so constructed as to entirely eliminate, or at least greatlyreduce. the sweating of the tank.

Flushing and similar tanks collltl'tlclfll tl" sheet metal and enann-led are sightly and sanitary but are objectionable on account of the sweating or condensation of n oistnre on their outer surfaces. Various constructions and arrangements to avoid sweating or take care of the condensation have been devised.

The present invention has for its object a tank 0 the character named which is so constructed as to eliminate, or practically eliminate, the sweating. or condensation referred to,

T e invention comgzises a tank constructed as hereinafter descri d and claimed.

In the aceom anying drawing Figure 1 is a rear view of t e tank partly broken away; Fig. 2 is a vertical transverse section through the same; Fi 3 is a plan view, partly broken away; l ng. 4 18 a perspective view of the blank from which the bot y )ortion is formed showing the same partly -nt. up; Fig. 5 is a sectional view of a modification: and Fig. (l is a, perspective view of icntmn.

.'l be tank may he of any suitable shape and size, preferably of rectangular form with roamed corners as is the vpreaent practice in llnshin tanks. The tank has a front wall 1, em walls 2, rear wall 3 and bottom 4.

The front and end walls are double, that is formed with an outer Sheet 5 and an inner sheet 6 se arated by the intervening air :4 race 7. '1 his double wall at the front and t to two ends is preferabl formed from a. single sheet which is out o the she )e shown in Fig. 4 and then folded alon f t a line 8 to bring the two parts paralle and form the rounded connecting portion 9 which forms the top edge of t 10 ank.

portion 10 of the blank forms the outemwall and the narrower portion 11 forms the inner walls. The wider part 10 has its edge rfolded inwardly to clo'l the sure 7 at the bottom of the walbnflbe onble plate is bent to form the fmntt-ahd the end wall and 18 are fol ed inward 8 and bottom-4 are pre a single and of a size to have its edges the bottom and ed portion (5- sndwwith t e edyis ol-the inturned porttonslQand 1 3 oft e onter llteet. These parts are united in any sintable'sgay, such as by solderm brazm or-whldtng, Kreferably by welding by t to eleetti low pipe system. Smee the edgds d! the parts abut. a single welded joint served to unite the bottom or back to the indohnd front wall portions and also unite the of the inner and outer end wall= There is a vertical joint 14 of this character along the back near each end and also a joint 15 on the bottom extending acroI-near each end and near the front. t vi.

Fig. doubled walls have their open al a upwardly. the rounded conncctmg portaen 9 being at the bottom. In this case-theta space 7 is not hermetically sealed, audit-litre. l to 3. Fig. 0 shows another modlfiiatin in which the double wall extends: and andforms the back as well as them send front of the tank, the double wallallw uig their ends meeting on the back atflet 'lzhe rounded connecting portion 9 in lllll Infldliir eatiou may be at either top or bottom- ,The meeting edges are weld. and the joint is then I to smoothen it and reduce the thickness-at the weld to substantially the thickneaa. of sheets so as to secure a uniform coating of enamel. v The front wall may prolect out slightly at the top and also near tie bottom for a more ornamental eflect and to more efl'ectually retain the enamel. The entire body after completion is covered w|th enamel and the surfaces of the air space 7 will be either galvanised, paintedmr enameled in order to prevent. corrosion. For this a one of the sheets will be provid ytth a hole through which the coating l quid can be mly. Theba' wall portions;

A cover of any su table shape will be provided. The tank will be provided with the usual openings in its bottom or elsewhere for the supply pipe or valve and for the flushing valve or outlet pipe. and will also be provided with any smtable valve mechanism and operating means.

The tank described has a body formed of two sheets unitedhy a ,sm le omt thereby reducing to a nnnnuum tie abor costin manufacture. The front and and walls are hollow and in the preferred form provide a hermetically sealed dead air space which practically overcomes all sweating or condensatimu- The back is usually in contact with the wall so that sweating at this point is reduced to a minimum aml the bottom is of restricted area so that the amount of condensation thereon is not sutlieieut to he objectionable. It may be covered by a water-proof felt mat which acts as a noncondnctor and prevents sweating.

What I claim is:-

l. A sheet metal flushing or ltkG tank having its front and end walls formed double and spaced apart and providing a hermetically sealed air space, and a bottom and back secured to said double walls.

2. A sheet metal flushing or like tank havmg double walla spaced apart and formed from a single sheet of metal doubled on itself to form the inner and outer walls, and a bottom secured to said double walls.

8. A sheet metal flushing or like tank having double walls spaced apart. said walls being cmnposed of a single sheet of metal doubled on itself to form the inner and outer walls, the bent or curved portion forming the top of the tank, and a bottom securfid to the free lower edges of said double wa 4. sheet metal flushing tank havin front and end walls spaced a art and fOllllQt from a single sheet of meta doubled on itself to form the Inner aml outer walls, the bent or curved part forming the top ofth tank, and a bottom and back secured to t e lower so edges of said walls.

' 5. A sheet metal flushing or like tank having double Walls spaced apart and formed from a single sheet of metal doubled on itself tofurm the inner and outer walls, a rear wall mured to the free vertical edgesof the double end walls and a bottom secured to the lower edges of the double end and front walls.

0. A sheet metal flushing or like tank having double walls spaced apart'and formed from a single sheet of metal doubled on itself to form the inner and outer walls, the edges of the outer portion bein bent inwardly and meeting the edges 0 the inner portion, and, a bottom secured to the free edges of said outer and inner walls.

7. A sheet metal flushing and like tank having double front and rear walls spaced apart and formed from a single sheet of metal doubled on itself to form tlie inner and outer walls. the outer wall portihar hav; ing its rear vertical edges and its edges bent inwardly and me ting the edgesv of the inner wall, and the back and bottom having their edges contactin with the free edges of the wall portion an 'oined thereto.

8. A sheet metal flushing or ike tank havbott m 7 ing double walls with a hermetically sealed air space there-between. and a back and bottom, the meeting edges of said parts being united by a welded joint.

i). A sheet-metal flushin or like tank having double walls separat 'by a hermetically sealed'air space, and a bottom and back, the

edges of the bottom and back end of the inner and outer wall portions being united by a single joint. k

10. A sheet metal flushing or like tank having the meeting edges of the sheets welded and reduced to substantially the thickness of the sheets. the whole being covered with a coating of enamel.

11. A sheet metal tiushing or having the meeting edges of the sheets joined by a butt weld joint which is and the whole covered with a coating of enamel.

In testimony whereof, I have hereunto set my hand.
