IRVING BLOUNT, OF BROOKLYN, NEW YORK.

TANK.

Specification of Letters Patent.

Patented June 26, 1917.

Application filed February 6, 1915. Serial No. 6,611.

To all whom it may concern:

Be it known that I, IRVING BLOUNT, a citizen of the United States, and a resident of the borough of Brooklyn, city and State of New York, have invented certain new and useful Improvements in Tanks, of which the following is a specification.

My invention relates to an improved construction of tanks or other like containers to be used in the treatment of different materials, especially garbage, refuse and the like.

One of the objects of my invention is to so construct the tank that the temperature of the material to be treated therein will remain uniform for a comparatively long period of time. I 7

Another object of my invention is to so construct the tank that it will be strong and efiicient in operation and may be manufactured and assembled at low cost.

Other objects will appear from the hereinafter description taken in connection with the accompanying drawing which forms a part of this specification.

Referring to the drawing in which one construction of my invention is illustrated;

Figure 1 is a longitudinal section through the center of the tank.

Fig. 2 is a fragmentary side view showing a bracket by which the tank may be mounted upon proper supports.

Fig. 3 is a longitudinal section of a modified construction. v

The part marked 10 on the drawing represents the cylinder of the tank which is preferably constructed of metal, to one end of which is secured a dome shaped head 11, by suitable means, such as rivets or bolts 12. To the other end of the cylinder or body of the tank is secured by means of suitable bolts or rivets 13 a funnel shaped end or head 14. In the dome shaped head 11 is an opening 15 and connected to the head and communicating with the cylinder through the opening. 15 is a pipe 16, to which may be connected the feed pipe not shown. A similar section of pipe 17 is secured to the lower end of the funnel shaped head 14. This piece of pipe is provided with outturned flange ends 18 which are bolted or riveted on the outside of the funnel shaped head 14. On opposite sides of the tank are secured the reinforcing plates 20 and 21. Secured to these reinforcing plates by means of bolts or rivets 22 and 23 which extend through the wall of the tank are. L shaped brackets 24 and 25 which support the tank on a suitable bed or housing not shown. These L shaped brackets are provided with strengthening ribs 26 and 27. Surrounding each of the reinforced plates 20 and 21 are spacing members 40 and 41 which are substantially Z shaped in cross section. One flange 42 or 43 is secured to the wall 10 of the tankand the other flange 44 or 45 projects outwardly in the manner shown in the drawing. 46 is an outer cylinder or jacket somewhat larger in diameter than the main cylinder or wall 10 of the tank. Holes 48 and 49 are cut in this jacket at opposite sides thereof. openings extend the spacing members 40 and 41. The rims 50 and 51 where the holes are cut in the jacket are secured to the outturned flanges 44 and 45 of the Z shaped spacing members 40 and 41. To the edge 52 of the jacket is secured an L shaped ring 53. One flange of this ring is secured to one limb 5a of the expansion ring 55 which is U shaped in cross section, the other limb 56 being secured to the outwardly extending flange 57 of the ring 58 which is secured to the upper end of the tank 10. The opposite end 46 of the jacket 46 is funnel shaped and the edge 46 is bolted to the outer face of the flange 18 of the pipe 17 By the construction as hereinabove described, the jacket is separated from the main body 10 and the funnel shaped head 14 of the tank, leaving spaces a and 1) between the tank on the shell.

In the modified construction shown in Fig. 3, the outer flange of the spacing member 40 or 41 is overturned at 45 to form an expansion connection similar to the expansion ring 55 hereinabove described. The edge 50 or 51 of the jacket 46 is outturned to form the flange 51, by which the jacket is connected to the limb 45 of the expansion member.

All the parts are tightly corked or fitted so that there may be a vacuum in the spaces a and b. The expansion joints are so constructed that there may be the proper amount of expansion between the jacket where it is connected to the upper end of the tank. The lower part of the jacket is so shaped that it is not necessary to provide any expansion connections, as the change in temperature will allow the part of the jacket at 0 to expand toward or from the body of the tank without undue strain.

In operation, the material to be treated is placed in the tank through the opening 15,

Through these and the lower pipe 17 in this case may be closed. When the tank is filled with the material steam or hot water is admitted thereto through the pipes 19 and the temperature of the material may be materially raised. On account of the construction of the tank there will be a comparatively small amount of radiation of heat and the material will be treated for a long time without the loss of heat or without the necessity of supplying more steam thereto.

I/Vhile I have described my invention as adapted for the treatment of garbage and other material, it may be used for many other purposes where it is desired to retain the temperature of the material in the tank. If the material is to be treated cold, or at a low temperature, or if the material placed in the tank is to be retained at a low temperature, the construction of the tank is such that this also can be efliciently accomplished.

It is obvious that the vacuum between the walls of the tank may be produced by attaching an ordinary vacuum pump to the tank at either wall, preferably the outer wall, the attachment being effected at an opening made for the specific purpose and subsequently closed, or to a permanent vent not shown which may preferably be provided with a valve for opening and closing the same.

While I have shown certain features of my invention in the accompanying drawing, it is to be understood that said drawing is merely illustrative, and that I am not con- Copies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents,

um acket being free from and surrounding said supporting brackets, said supporting brackets being secured only to the wall of the tank. 2

2. A tank or container having a main inner. wall and a surrounding outer wall secured thereto by air-tight connections, a plurality of supporting brackets secured to the inner wall, expansion joints between the outer wall and the inner wall surrounding said supporting brackets.

3. A tank or container having an inner wall, a plurality of supporting brackets secured thereto, a Z-shaped flange secured to the inner wall surrounding said supporting brackets, an outer wall surrounding the tank and secured thereto by expansion joints.

In witness whereof I have hereunto set my hand at the city, county and State of New York, this fifth day of February, 1915.

IRVING BLOUNT.
