IMPROVEMENT IN STEAM-RADIATORS.

Specificationl forming part of Letters Patent No. 175,241, dated March 28, 1876; reissue No. 7,139, dated May 30, 1876; application iiled May 2, 1876.

To all whomz't may concern Be 4it known that I, JOHN O. COPE, of the city of Philadelphia, in the county ci' Phila`- delphia and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Radiators; and l do hereby declare that the following is a full, clear, and exact description thereof', that will enableothers skilled in theart to which it appertains to make and use the same, to the accompanying drawings, and to the letters otlrefercnce marked thereon, which form a. partot this specification.

My invention relates to radiators where the radiator is Aplaced in the cellar, or lower part of the building, and the heated air carried through pipes or iues through the building; and the nature of my general arrangement ot' parts, as will be hereinafter more fully set forth. l.

.In the accompanying drawing, Figure'l is a central vertical section yof my improved radiator.

A represents the chamberor-case of the radiator, with doors B Bat the front end. C

is the inlet-pipe. for cold air, and D the exitpipe forhot air. E is the pipe at the top of thev coil, through which the steam enters. E is a similar pipe at the bottom of the coil. G G are the pipes forming the steam-coil, and H H are the return-bends.

My inventiol-iis a horizontal steam-heater ot' wrought-iron pipe, to'beplaced in the cellar or lower partei' a building, to act 'as a heater by radiatioin'froin.which the heat is to ascend through dues constructed for the purpose. y 1 The steam williirst enter the coil through the pipe-E at the top, running crosswise of the coil, to which the nrst row of pipes G are attached, and the pipe diameter' to supply-all the pipes G with their quota ofsteam, each row of wrought-iron pipes G to be set at a slight inclination to allow ot' drainage for the condensation.

The ends of the pipes G are connected by` return-bends H H, made 'in two parts. One e'nd of each part is tapped to suit the pipe, and the other end is iitted with a anged ground joint, li, suitable for lead or rubber, and bolted to a corresponding joint, thus forming the return-bend. The opening in the mund-joint end of the half return-bend i8 li i reference being had thatclass of steambot-toni is precisely the. construction andA Figs. 2,3, and 4 are detailed views of tlie returnbends.

E will be of sucient little oblong in the direction of the which it is attached, to admit a full dow of steam in case otl any variation in length of pipe. The bolt-holes are also made oblong or elongated, and parallel with the opening in the flanged end of half return-bend. The pipe E is made ot' cast-iron, in sections, so that the heater may be enlarged without disturbing the part already on its under side, provided with short necks a, at Isuitable intervals, and each-neck tted with a fianged ground joint, to correspond with the anged jointof the return-bend, which forms the connection with the first row ot' pipes G. The pipe E has also a iianged ground joint at each end, to which another section of the heater maybe added.

similar, except that the necks are on the upper instead of the under side. The coil is supported by buck-stays J, two on each side at the ends, to which iron rods I are bolted, said rods passing under each horizontal row of pipes. y

The chamber A, surrounding the heater, is to be as near airtight as possible, with the exception 0f the supply and delivery pipes.

The supply-pipe (l, for fresh air, is intropipe to duced at the very lowest part of the front ot' y chainber'A, and is to-extend to thefroof ot the building being heated. The delivery' or hotair pipe D is in the extreme upper part of the back end of the chamber, and in a line drawn diagonally from the pipe U, both of said pipes being provided with suitable dampers b.

The half return-bend H forms an acute angle from the tapped tothe ground-joint end, thereby giving' the proper inclination to the pipesG. Y

Having vthus fully described my invention,

- what I claim as new, and desire to secure by Letters Patent, is The combination of the chamber A, coldairpipe C, hot-air pipe D, sectional steam-v pipes -E E', inclined pipes G,constr`ucted and arranged with bisected return-bends H H, sub,

stantially as and for the purpose Yherein set forth.. l In testimonyy that I `claim the foregoing I yhave hereunto set my hand this 28th day of April, 1876.
