UlTED STATES WILLIAM P. MGINTYRE, OF NEW YORK, N. Y.

BOILER.

Application filed March 6, 1923.

This invention relates to improvements in water tube boilers designed for use in steam or hot water heating systems.

it is the object of the present invention to provide a boiler in which hot water may be heated or steam produced quickly and with a minimum consumption of fuel and to provide a boiler having these advantages and the further advantage of simplicity and compactness in construction.

In the accompanying drawing,

Figure 1 is a sectional elevation of a boiler embodying my invention in its preferred form;

Figure 2 is a horizontal sectio 2 of Figure 1, and

Figure 3 is a horizontal section on line 3 of Figure 1.

Referring to said drawing, the boiler shown is designed for the heating of Water or the making of steam for use in heating apparatus. It comprises a tubular shell A between the inner and outer walls of which is provided a chamber A for the water to be heated. This chamber A is provided with an inlet pipe (4 from a suitable source of water supply and with discharge pipes Z) for the discharge, into the heating system, of the hot water or steam produced in the boiler, the boiler being also provided at its top with the usual pipe opening for the escape of the heated gases. It also includes a set of heating coils C, D all of which are cone-shaped, the central coil C being inverted and the others grouped about and in close proximity to it. Above these coils there is also provided a hollow mid-section or hollow disk E which communicates at its sides and top through tubes 0, a with the interior of the water chamber A, and each of the coils C, D communicates at 0, (Z respectively with the interior of the shell A and atc, d with the interior of the mid-section or disk E.

As a result of this construction, with the coils C. D communicating at their lower ends with the water chamber A and at their upper ends with the interior of the mid section E, and with said mid-section comon line Serial No. 623,105.

municating with the interior of the water chamber at the sides thereof and also at the top thereof, and with the coils grouped together in close proximity with each other, and the central one inverted, it will be observed that, in a very small area, a large quantity of tubular water-conveying members are grouped together and exposed to the heating agent in the tire box B so that a continuous circulation and rapid heating of water or making of steam is obtained. The coils thus grouped together in close proximity to each other serve as a baflle to the flames and heated gases, retarding their passage through the boiler and diverting them sidewise so as to insure contact thereof with all portions of the tubular casing and coils. The hollow mid-section E is also imperforate so far as openings through it to the smoke escape pipe are concerned, so that it also serves as a battle to the flames and heated gases, directing them radially outward toward the tubular casing and compel ling them to pass around and over the midsection in order to reach the smoke escape pipe.

lVhat I claim is:

In a boiler, the combination of tubular casing including a water chamber provided with inlet and outlet openings, a hollow midsection located in the upper portion of the casing and communicating at its sides and top with the water chamber, an inverted cone-shaped heating coil located below the mid-section and communicating at its lower and upper ends with the water chamber and mid-section respectively, and a plurality of non-inverted cone-shaped heating coils grouped about and in close proximity to said inverted coil andeach communicating at its lower and upper ends with the water chamber and midsection respectively, said mid-section extending across the easing into close proximity to the inner wall thereof and closed to the passage through it of the heated gases to the escape pipe therefor.

In testimony whereof, I have hereunto set my hand.

WILLIAM P. MCINTYRE.
