IIVVENTOR I2 -1 BY ALBERT R. PRITCHARD, OF NEW YORK, N. Y.

HEATING APPARATUS.

Specification of Letters IEatent.

Patented Jan. 6, 1920.

Application filed November 28, 1917. Serial No. 204,313.

To all whom it may concern:

Be it lmown that I, ALBERT R. PRITCHARD, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Heatin Apparatus.

My invention relates to the art of heatmg and has as its principal object the provision of convenient means whereby the amount of heat radiated in a room may be controlled at will. I

Further objects of the invention will appear to those skilled in the art upon a perusal of the following specification and claims.

In the drawing filed herewith and formmg part of my application for patent, Figure 1 is an elevational view of a composite radiator embodying my invention. Fig. 2 is a detail view broken away to illustrate the interior construction of the lower part of the apparatus shown in Fig. 1.

Referring more particularly to the drawing, 1 is an inlet pipe connected to the hollow base 2 of a composite or compound radiator through an inlet valve 3, said base 2 having a pipe 2 therein which leads the steam supplied by pipe 1 to pipe or nipple l. Pipe 4 may be provided if desired with a second inlet valve 5 and conducts the steam or other heating fluid from the hollow base 2 to the lower end of the radiator element 6. Leading from the upper end of the radiator element 6 is an outlet pipe 7 provided with a valve 8, the pipe 7 connecting with the hollow top member 9 of a second radiator element arranged to receive its heating fluid from the first-mentioned radiator element 6. The said second radiator element or unit comprises a plurality of down cast members such as 10, which lead from the member 9 t0 the base member 2, connection being provided Within the base member 2 between the lower ends of the down cast members 10 and the final outlet pipe 11. Pipe 11 has a valve such as 12 therein.

From the foregoing it will be seen that the amount of radiating surface in use can, according to my apparatus, be efliciently and conveniently controlled by closing or opening the valve 8 intermediate the first and second elements. It will be understood that when element 6 only is in use, the apparatus is operated upon the one pipe principle. In the arrangement shown and described, the

apparatus operates upon the two pipe principle when all the heating surface is in use. However, it will be evident that the apparatus can be arranged to operate upon the one pipe principle when all the heating surface is being employed without departing from the spirit of my invention.

It will be seen, also, that more than two radiator elements may be arranged accord ing to my invention to receive the heating fluid one from the other in series, and that the relative size and disposition of the heating elements is immaterial.

Having thus described my invention, I claim:

1. In a heating apparatus in combination, a radiator element, inlet connections at the lower part of said element, a second radiator element, a connection intermediate said radiator elements leading from the upper part of said first-mentioned element, a valve in said intermediate connection, a valved inlet to said first element and a valved outlet from said second-mentioned element.

2. In a heating apparatus, a radiator comprising a hollow base member, a hollow top member, radiator members intermediate to said base and top members, and a radiator unit intermediate said base and top members, said unit having avalved connection with said top member.

8. In a heating apparatus, a radiator comprising a hollow base member, a hollow top member, radiator members intermediate to said base and top members, a radiator unit intermediate said base and top members, and valved connections between said unit and said base and top members.

4:. In a heating apparatus, a radiator ap' paratus comprising an upcast unit including a plurality of radiating members, a. downcast unit receiving steam from said upcast unit and including a plurality of radiating members, a valve whereby the flow between said units may be controlled, and a valve whereby the inflow of said upcast unit may be controlled.

5. In a heating apparatus, a radiator apparatus comprising a unit having hollow top and bottom members, and means, for conducting heating fluid between said members, and a second unit comprising a plurality of radiating members connected as a whole to said top member of said first unit.

6. In a heating apparatus, a radiator apparatus comprising a unit having hollow top top and bottom members and means for conducting heating fiuid between said members, 10 a second unit suspended as a whole between said top and bottom members, and a valved connection between the top of said second unit and said top member of said first unit.

ALBERT R. PRITOHARD.
