IMPROVEMENT IN RADIATORS.

Specification forming part of Letters Patent No.

151,170, dated May 19,1874; applicatirn filed February 2, 1874.

To all whom it may concern Be it known that 1, JOHN SPRINGER, of Clinton, in the county of Rock and State of Wisconsin, have invented an Improvement in Radiators, of which the following is a spcciti cation:

This invention relates to improvements in the construction of that class of radiators usually denominated as stove-pipe drums; and has for its object so constructing the same that, while acting in its legitimate capacity as a radiator, it will also, to a certain extent, operate as a regulator of the draft, and keep its Figure 1 is a vertical section through the center of my radiator. Fig. 2 is a perspective of the interior part of the same with the Like letters indicate like parts in each figure.

In the annexed drawings, A represents the outer case, provided with inlet-pipe a and outlet-pipe b at opposite ends, through the cen' ter of the heads at. B is the inner drum, provided with inlet-pipe Itand outlet-pipe k. 0 G are two collars, sleeved one on each of the pipes h and 7c, and the ends of these collars are connected together by the metallic straps m, the whole forming a frame, to which is secured spiral flange E," which is designed to nearly or quite fill the space between outer and inner-drums. D is a stop, operated from the outside of the drum A, and so arranged that at will its inner end may be made to rest against one of the collars O.

the outlet-pipe b.

frame and flange will revolve, thereby increas{ ing the draft, while at the same time it will prevent the deposit of soot uponthe inner walls of the flue. The cold air enters the in ner drum B through the pipe h. The air in its passage through this drum is heated by the radiation of heat through. its wall, and finds an exit through the pipe is into the same or adjoining rooms.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In heat-radiators, the remlving flue, madeby the. spiral flange E, arranged to revolve between the inner drum B and theouter drum A, substantially as and for the purposes set forth.

2. The combination of the drums A B, pipes to b h k, collars O 0, stop vD, spiral flange E, substantially as described and for the purposes set forth.
