CHARLES M. HANNA, 0F LOGANSPORT, INDIANA STEAM-HEATING SYSTEM.

Application filed September 26, 1913.

To all whom it may concern Be it known that I, CHARLES M. HANNA, a citizen of the United States, residing at Logansport, in the county ofCass, State of Indiana, have invented certain new and useful Improvements in Steam-Heating Systems; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in steam heating systems and more particularly to means for effecting the free, continuous circulation of steam therethrough.

It has for its object to provide a continuous, uninterrupted, automatic circulation of steam from the boiler through the system of pipes and radiators and return by means of a vacuum device connected therewith.

It still further has for its object to provide a heating system which is simple, durable and inexpensive in construction, easy to operate and very effective and satisfactory in use.

The invention consists in the several features and the combination and arrangement of said features as more fully hereinafter described and claimed.

Referring to the drawings :-Figure 1, is a perspective view of my heating system ready for use. Fig. 2, a sectional view taken through the boiler, showing the feed plpes, drain pipes, condenser pipe for returning Water of condensation from the condenser to the boiler and the air duct for supplying air to the condenser.

In the drawings in which similar reference characters denote similar parts throughout the several views, 1 represents a steam boiler, which may be of any well known make or construction, provided with an outlet pipe 2 which is connected to a continuous system of pipes 3, which feed or dehver steam to the several radiators, connecting with return pipe 4 of the boiler. It Wlll be seen that the outlet pipe 2 is placed over the hottest oint of the boiler while the return pipe 4 1s placedover the coolest point of the same.

A series of radiators 5 are provided each of which is connected to the system of feed pipes 3 by means of a short pipe 6, and 7 are valves for regulating the inlet or steam Specification of Letters Patent.

to said radiators. A system of drain pipes 8 connect with each radiator by means of short pipes 9, and 10 are outlet valves for regulating the draining of the radiators through said pipes.

The system of drain pipes 8 connect with and terminate in a condenser 11, a pipe 12 connects the bottom of said condenser with the boiler and serves to return the water of condensation from the condenser tothe boiler, and a pipe 13 connects the feed pipes 3 with the pipe 12 and serves to drain the feed pipes 3 into said pipe 12 and thence to the boiler. An air duct 14 is connected with the top of the condenser 11 and is adapted to extend through the Wall of the building in which the heating system is located or installed and furnish cool air to the condenser, and 15 is a damper in said duct for regulating the inlet of air therethrough to the condenser. A pipe 16 extends laterally from the lower portion of the condenser 11, its outer end being provided with an exhaust valve 17, and 18 are vacuum valves mounted on said. pipe 16.

The operation is as follows :The steam from the boiler passes into the system of feed pipes 3 through pipe :2 and enters the several radiators through the short pipes G, the amount of steam fed being regulated by means of the valves 7, and the steam pushes the air and causes it to pass out of the radiators, together with any water condensed from the steam, into the system of drain pipes 8 and from thence into the condenser 11 and it then passes, in advance of the steam, into the vacuum-valves. The water resulting from the condensed steam, is returned to the boiler from the condenser 11, which is preferably above the water line of the boiler, through the pipe 12 and the feed pipes are drained through pipe 13 into pipe 12 and from thence into the boiler, thus affording a complete automatic, continuous, circulation of steam throughout the entire heating system, the steam being fed from the hottest point of the boiler and returned to the coolest point of the same.

The valve 17 is for the purpose of afi'ording means for exhausting the steam when it is desired.

I do not desire to be understood as limiting myself to the specific details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement in the adaptation of the device to various conditions of use Without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variations and modifications as properly fall Within the scope of my inve tion and the terms of the following claims.

What I claim is 1. In a steam heating system, a boiler, a condenser, a series of radiators, a system of steam feed pipes connecting the boiler with said radiators, a system of drain pipes connected to said radiators and terminating in the condenser, vacuum valves connected to said condenser, a duct connected to the upper portion of said condenser for admitting cool air to the outside of said condenser, means for regulating the admittance of air through said duct and a pipe for returning the Water from the condenser to the boiler, substantially as described.

:2. In a steam heating system, a boiler, a series of radiators, steam feed pipe connecting said radiators With the boiler, drain pipes connected to said radiators, a condenser connected to said drain pipes, a laterally extended air duct inclosing the upper portion of the condenser and adapted to admit cool air to the outside of the same, vacuum valves'connected to said condenser and means for returning the Water vfrom the condenser to the boiler, substantially'as described.

In testimony whereof, I aflix my signature in the presence of tWo Witnesses.

CHARLES M. HANNA.
