UNITED STATES PATENT FFICE.

CHARLES WHITTIER, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND BENJAMIN F. CAMPBELL, OF SAME PLACE.

IMPROVEMENT IN STEAM-HEATERS.

Specification forming part of Letters Patent No. 86,1180, dated February 2,1869.; antedated November 10, 1868- To all whom it 'may concern:

Be it known that I, CHARLES WHITTIER, of the city of Boston, in the State of Massachusetts, have invented certain new and useful Improvements in Steam-Radiators and do h ereb y declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the iigures and letters marked thereon.

Of these drawings, Figure 1 is a plan view of a number of sections of a radiator. Fig. 2 is' a longitudinal vertical section taken through the line a' x of Fig. 1,.and Fig. 3 is a cross vertical section taken through the line y y, or, in other words, a view of the cap, connectin g two sections, removed.

Similar letters of reference indicate corre` sponding parts in the several figures.

My invention relates to an improvement in radiators intended for indirect radiation, the sections being placed horizontally together or side by side, and one or more layers being properly connected and incased.

In :my application .for Letters Patent for improvements in radiators, filed contemporaneously with this, I find it difficult to cast perfectly the sections therein mentioned more than four feet long. It is therefore necessary,'when sections are required of a greater length, to cast the pipe separately, and then attach caps upon the ends of these sections, in pairs or alternately.

The round pipes have heretofore been attached to the caps by being screwed up to the latter. This was, however, found quite inconvenient and expensive.

For my class of radiator I cast a cap, e, as shown in Fig. 3, with four lugs, b b b b, and also have corresponding lugs c c cc on the ends of the pipes d d, Svc., and these lugs contain slots e e e e at their outer ends, into which are'inserted bolts ffff, each lug on the cap being opposite to its corresponding one on the pipe. These bolts are provided with nuts, so that they will, upon being tightened, draw closely together .the cap and pipes.

The cap is constructed internally so as to permit of the passage, from one section of pipe to the other, of the thin body of steam in about the same condition as it is while pass ing through such sections of pipe.

I do not mean to be understood as claiming 'i the round pipe connected to caps with screws and nuts, as ordinarily practiced; but

What I do claim as new, and desire to se cure by Letters Patent, is

Sections of flattened pipes, the ends at tached, in pairs, by caps a, such caps being connected to the pipes by the lugs b b b-b, c o c c, and bolts f f f f, substantially in the mannerdescribed.
