HAMILTON, CANADA.
HOT-WATER BOILER OR TANK.
SPECIFICATION forming part of Letters Patent N 0. 616,030, dated December 13, 1898.
Application filed November 15, 1897. Serial No. 658,548. (No model.)
at Toronto, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Hot-\Vater Boilers or Tanks, of which the following is a specification.
This invention relates to hot-water boilers or tanks, and pertains more especially to boilers or tanks utilized in connection with a range or stove in which the contents of the boiler or tank is heated by means of pipe connections with a water-front or water-back located in the fire-pit of the range or stove; and the object of the invention is to provide a boiler of this character which shall be of a maximum strength to Withstand the pressure of the contents thereof when expanded and which shall be cheap of construction and of a minimum weight commensurate with the requisite strength.
The invention consists in the parts shown in the drawing, described in the specification, and more specifically pointed out in the claims.
In the drawing the figure illustrates a partial longitudinal vertical sectional view of a boiler or tank constructed and arranged in accordance with my invention.
, Heretofore in the construction of hot-water boilers or tanks the tanks have either been formed of sheet metalsuch as galvanized iron, sheet-iron, steel, &c.-in order to secure a light inexpensive boiler, or of a sheet of copper, which must be of sufficient thickness to withstand the pressure of the contents of the boiler when heated. The objection to the tanks of sheet metal is that they corrode and are only of a limited life,while the copper tanks are heavy and expensive and are not used to a large extent for that reason.
Referring to the drawing, in the construction of the tank I employ two similar malleable cast-iron rings 1, one at each end of the tank, to which the body and the top and bottom, respectively, of the tank are secured.
and an inner concentric portion 3, provided with an internal flange 4, upon which the outer edge of thetop and bot-tom, respecternal surface.
Arranged between the rings 1 and embracing a portion of the body2 thereof to a point slightly above the groove 6 is a cylinder 7, of copper or other like non-corrosive metal, the ends of the cylinder being contracted or forced into the groove 6 in the body-of the rings and secured thereto by a winding of wire 8, preferably gun-wire or wire of a great tensile strength, wound to a degree to be flush with the exterior surface of the cylinder 7.
Surrounding the cylinder 7 and of an internal diameter substantially equal to the external diameter of the cylinder 7 is a cylinder 9, of sheet-steel or other light material of great tensile strength, the cylinder 7 being of a length to extend beyond the rings 1, the ends being bent over the web 5 and embracing the same, as shown at 10. 1
11 and 12 designate, respectively, the upper and lower heads of thetank, formed of malleable cast-iron, each being of a diameter'to rest upon the flange 4 of the rings 1 and pro- Videdwith an inwardly-projecting boss 13, screw-threaded internally to receive the ends of a tubular rod 14, by which means the heads are secured together and in engagement with the flanges upon the rings 1. The head 11 is provided with internally-screw-threaded annular lugs 11 11 to receive the pipes for securing a circulation of water in the waterback or water-front, and the head 12 is provided with a like lug 12, into which a suitable draw-off pipe screws.
found around the outer layer of the cylinder for a short distance ata point substan tially midway its length is a layer 15 of wire, preferably gun-wire or similar wire of great tensile strength.
The preferred means for securing the ends of the wire to the outer cylinder is to provide diminutive apertures in the outer cylinder, into which the ends of the wires are inserted and secured by sweating.
In order to render the tank thus described perfectly water=tight and at the same time to secure the several parts of which it is composed together, they are sweated together during the operation of forming the tank as follows: The rings 1 are first placed in a lathe and the outer peripheral surface is trued, when they are tinned and the inner copper cylinder is secured thereto, as heretofore described. The outer steel cylinder is now secured upon the cylinder, and the ends are forced inward over the web of the rings, as described. The ends of the cylinders thus formed are then inserted into a suit-able sweating-flux provided for this purpose and the several parts are sweated together, when the heads,which are previously tinned, are placed upon the flanges and the rings are secured thereon, first, by the central annular connecting-rod, and, second, by sweating the edges of the flanges and the rings, which is accomplished through the medium of a blowpipe.
If desired, I may form the cylinder of wire wound around the inner cylinder, instead of sheet-steel, as heretofore described, and accomplish the object of myinventionto wit, provide a reinforcement for the inner noncorrosive cylinder.
It will thus be seen that the tank thus formed is water-tight and not liable to leakage due to corroding of the metal thereof, as all the parts exposed to the contents are either tinned or formed of a non-corrosive material, and which is of a maximum strength to withstand the pressure, the parts being rein forced and braced at the points of greatest strain. In order to secure the heads in place, I first sweat on the head 12 within the flanges 3 and screw the rod 14 into the boss 13 at the bottom. I next insert the top of the rod 14 into the threaded boss on the top head, and by utilizing the lugs 11 and 11 I am enabled to turn the head 11 so as to screw it down tightly upon the top of the rod and bring the bottom edge of the head down tight against the internal flange 3 of the ring at the top of the boiler. The edge of the head may then be sweated in the usual way in position.
' hat I claim is 1. A boiler or tank comprising annular end rings, an annular body interposed between same and secured thereto, internal flanges upon the rings, the heads having their edges resting upon the flanges and provided at the center thereof with threaded bosses and a central rod provided with screw ends fitting the bosses and means for turning the top head, so as to bring it down in place after the bottom head has been fastened as and for the purpose specified.
2. A boiler or tank comprising annular end rings, said rings comprising a body portion and an inner concentric portion joined by an integral web, an annular groove in the outer face of the body of the ring, in combination with a cylinder of copper or other non-corrosive material, the end fitting upon the body of the rings and depressed into the grooves and an outer cylinder fitting upon the aforesaid cylinder, the end projecting beyond the rings and bent over the webs thereof and heads fitting upon the rings and secured thereto, the severalparts being joined together by sweating, substantially as described.
3. A boiler or tank comprising annular end rings, said rings comprising a body portion and an inner concentric portion joined by an integral web, an annular groove in the outer face of the body of the ring, in combination with a cylinder of copper or other non-corrosive material, the end fitting upon the body of the rings and depressed into the groove, a winding of wire upon the cylinder ends housed in the grooves, and an outer cylinder fitting upon the aforesaid cylinder, the end projecting beyond the rings and bent over the webs thereof and heads fitting upon the rings and secured thereto, the several parts being joined togetherby sweating, substantially as described.
In testimony that I claim the foregoing as my invention I have signed my name in the presence of two subscribing witnesses.
JOHN II. STONE.
