HOT-WATER H EAT-RADIATO R.

SPECIFICATION forming part of Letters Patent No. 498,849, dated J une 6, 1893.

.Application led May 7, 1892. Serial No. 432.218. (No modelJ To all whom it may concern:

Be it known that I, GEORGE W. I-IAWES, of Ortonville, in the county of Big Stone and State of Minnesota, have invented new and useful Improvements in Hot-Water Heat-Radiators, of which the following is a full, clear, and exact description.

This invention relates to what are termed hot water radiators and to the pipes and valves through which the hot water is conveyed to and from the radiators and consists in certain novel constructions and combinations of parts in such radiators and the piping connected therewith substantially as hereinafter described and more particularly pointed out in the claims.

Reference :is to be had to the accompanying drawings forming a part of this specification in which similar letters of reference indicate corresponding parts in all the views.

Figures l and 2 represent views of a hot water radiator having two loops or sections, A and 13. with a feed pipe U and an exit pipeO connected therewith: also showing a ley-pass pipe D E extending from the feed pipe to the exit pipe and in contact with the radiator. Fig. l shows the by-pass pipe D E passing under the radiator while Fig. 2 represents the by-pass pipe extending through the base of the radiator. Fig. 2 further shows the radiator as having a hollow base so constructed as to inolose the by-pass pipe D E Fig. 3 is a side View of the combination of pipes y U C D E G II to be attached tothe radiator, as shown in Figs. l and 2. Fig. 4. represents a View in perspective of the lower portion of a radiator in all respects the same as Fig. 2 excepting that the pipes R and S are short pipes attached to the radiator and that between the two pipes R and S is a duct T through the radiator by which they are connected. That portion of the radiator below the line F is solid except an opening or hollow space through which the pipe D E may extend, as in Fig. 2, or as represented in Fig. 4 by the duct T. Fig. 5 represents a side view of the comi( U 73 C C 9) R 77 S 97 (C G 37 H to be attached to the radiator as in Fig. 4.

In operation the hot water will circulate upward through the feed pipe U H into the radiator and return through the exit pipe G C and will also circulate through the by-pass pipe D E but when the valve I is closed the circulation will continue through the feed pipe, the by-pass pipe and the exit pipe U D E C but not through the upper portion of the radiator and the water in the upper portion of the radiator will remain still and become cool while the continued circulation through the by-pass pipe D E will prevent freezing in the radiator, and when the valve I is again opened a much less time will be required to heat the radiator.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a radiator, a feed pipe and an exit pipe therefor and a by-pass pipe or duct extending from the feed pipe to the exit pipe and in contact with the radiator substantially as described and for the purposes specified.

2. The combination in a radiator of a base of such shape as to allow a by-pass pipe to extend through and be inclosed therein, a feed pipe, an exit pipe and a by-pass pipe or duct extending through the base from the feed pipe to the exit pipe substantially as described.
