lVlPROVEMENT IN STEAM OR HOT-AIR PIPES.

Specication forming part of Letters Patent No. 36,141, dated August l2, 1862.

To all whom it may concern:

Be it known that I, R. T. CRANE, of Chicago,

in the county of Cook and State of Illinois,

have invented a new and Improved TfConnection for Heating-Pipes; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the accompanying drawing, making a .part of this specication, said drawing representing a longitudinal vertical section ot' my invention. y

The object of this invention is to arrange the pipes which are used for heating buildings or rooms by steamor hot air in such a manner that the steam or hot air can be passed through one or more of said heating-tubes and the heat regulated in a simple, cheap, and expeditious manner.

This invention consists inthe arrangement of one or more partitions between the ends of the heating-tubes,in combination with two or more inlets and two or more outlets, in such a manner that the steam or hot air admitted through either inlet passes through a portion of the pipes only, and that by these meansa portion of said pipes can be heated while the rest remain cold, and that the heat radiating from.

the heater can be regulated at pleasure.

To enable those skilled in the art to make and use my invention,I will proceed to describe its construction and operation with reference to the drawing.

A A representaseries of heating' pipes, the ends of which are inserted into T-connections B B', similar to pipes and connections used for steamheaters of the ordinary construction.

With ordinary heaters the steam or hot air is admitted to the T-connection at one end and out through the T-connection at the opposite end of the heating-pipes, and in order to pass from the inlet to the outlet opening said steam or hot air has .to pass through all the pipes, and consequently the heat which is transferred from the steam or hot air to the pipes radiates with equal force from the surfaces of all the pipes. By this arrangement the temperature in the room or building to be heated cannot be regulated. The steam or hot air can either be admitted 0r cut oft, and when admitted the temperature of the pipes will rise sooner or later to a degree nearly equal to that of the Steam or hot air, and. the heat in the room or building becomes oppressive on mild or com'- paratively mild days, and if the heat is cut off all the pipes become cold and the temperature in the room or building is reduced nearly to that of the outside atmosphere. cases, therefore, it will be too hot when steam or hot air is admitted to the'heater and too cold if the steam or air is cut oft. This difficulty I have obviated by means of one or more partitions, a a', which are inserted into the T- connections B B between the ends of adj oining pipes, as clearly shown in the drawing, and the inner space of said connection is thereby divided in two (or more) compartments, b cb c. The lower compartment, c, of the T-connection B communicates with the steam or hotai'r pipe through the inlet-opening d, and the upper compartment, b', ofthe T-connection B communicates with the discharge-pipe through the eXhaust-opening d. AThe compartments b and c are provided with openings e e', and the opening e admits steam or hot airinto the upper tier of heatingpi pes, A, whereas the opening e serves to discharge the steam or hot air from the lower tier of pipes, A. The pipes .leading to and from the openings d d e e are provided with suitable stop-cocks, so that the steam or hotV air can be admitted into either one of the compartments b c and discharged from the corresponding compartment, b or c', as may be desired. If it is desired to use the lower tier of pipes, A,alone,the steam or hot air is admitted into the compartment c, and thence hit passes through the pipes A to the compartment c and dischargeopening e.

If it is desired to use the upper tier of pipes, steam or hot air is admitted to the compartment b, from which it passes through thepipes A to the compartment b and out at the discharge-opening d. It needs no further explanation to show how steam can be admitted to both compartments b o and through all the pipes A A whenever it is desirable toobtain .the full heating power of the apparatus.

By increasing the number of partitions between the ends of heating-pipes and providing a corresponding number of inlet and outlet openings the pipes can be divided into as many tiers as may be desired, and the heat emitted from the heater canbe regulated at pleasure.

It remains to remark that` the T-connections In many,

B B', with the partitions a a', may be cast each in one or in several separate pieces.

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

The arrangement of one or more partitions, a a', in the interior of the T-conneetions B B and between the ends of heating-pipes A A',

in oonnbination with inletopenings d e and outlet-openings d e', substantially as and for the purpose shown and described.
