Nov. 15, 1931s. W. R. KÍEPLER 2,136,443 STAND FOR TANKS Filed Sept. 15, 1937 ATTORNEY. Patented Nov. 15, 1938 2,136,443 UNETEDA STATÈS PATENT OFFICE 2,136,443 STAND FOR TANKS William R. Kepler, Wauwatosa, Wis., assigner to A. 0. Smith Corporation, Milwaukee, Wis., a corporation of New York Application September 15, 1937, Serial No. 163,877 4 Claims. This invention relates to stands for support ing large tanks and is particularly applicable to the supporting of vitreous enamel lined beer storage tanks such as are disclosed in my Letters Patent No. 2,092,165 issued September 7th, 1937, for Supports for cylindrical vessels. The enamel lining of these tanks is fired in a furnace at a temperature of about 1700° F., at which temperature the metal of the tank is fairly soft. In the firing operation the tank is placed onto a preheated transfer car and moved into the heated furnace and iired until the enamel lining is sufliciently fused. The car is then with~ drawn from the furnace and the tank removed. This last step of removing the heated tank from the car Without injuring the heated tank walls or fused lining presents quite a problem. It is the object of the present invention to facilitate the handling of the tank in loading it onto and removing it from the car. An embodiment of the invention is illustrated in the accompanying drawing in which: Figure l is a side elevation of a tank supported by the beam of a crane or other suitable hoisting device; Fig. 2 is an end View of the disclosure of Figure l, showing the tank supported upon a transfer car; Fig. 3 is a vertical section of a supporting stand taken on the line 3--3 of Fig. 5; Fig. 4 is a vertical section of a stand taken on the line 4_4 of Fig. 5; and Fig. 5 is a top plan View of a stand. As disclosed in my Letters Patent mentioned above, the tank l is provided _at each head with a pair of supporting brackets 2. Each bracket has a horizontally disposed foot-plate 3 having a downwardly extending circular foot 4. The foot 4 has a socket 5 in its under side to be engaged by a hook 6 of a hoisting beam l supported by any Vsuitable crane or derrick (not shown). To permit the insertion of the hook 6 into the socket 5, a stand 8 is interposed between a sup porting base 9 and the foot 4. This stand is preferably composed of an alloy metal capable of withstanding the heat of several firing opera tions so that it may be used a number of times. It is detachably secured to the foot-plate 3 by bolts li! which pass through apertures in ears ll and I2 of the stand. The foot 4 engages a complementary socket I3 in the upper face of the stand and bears upon the base of the socket. The stand has the shape of a hollow truncated cone having an inturned reenforcing flange I4 at its base and an enlarged head l5 to provide for` thesocket i3. The wall thickness of the stand is substantially uniform to avoid excessive stresses in cooling. ’ . A vertical slot i6 is formed in the side wall of the stand to permit entrance of the hook 6 tothe socket 5 into which the hook is guided by the up wardly tapering inner wall of the stand. The stands are bolted onto the brackets 2 preparatory to hoisting of the tank and are posi 15 tioned so as to present their slotted sides to their respective hooks 6 for easy engagement and disengagement thereby. Various embodiments of the invention may be employed within the scope of the following 20 claims. I claim: 1. In combination, a stand for an object to be hoisted interposed between said object and a sup porting base, said stand having a slot therein, and 25 a hoisting hook to enter said slot and engage the underside of said object. 2. In combination, a stand for an object to be hoisted interposed between said object and a sup porting base, said stand being of tubular struc 30 ture and having a vertical slot in its wall, a hoist ing hook to enter said slol'J and engage a socket in the underside of sai-d object, and means within said stand to guide said hook into said socket. 3. In combination with a cylindrical tank to be 35 hoisted, a bracket secured to said tank and hav ing a socket in its underside, a tubular stand removably attached to said bracket and having a vertical slot in its side, a hook to enter said slot and means within said stand to guide the hook 40 into said socket as the hook is raised. 4. In a support for a cylindrical tank to be hoisted, a bracket secured to. said tank, and hav ing a socket in its underside, a tubular stand re movably attached to said bracket and having a vertical slot in its side to receive a hoisting hook for engagement with said socket.
