JOSEPH R. BOWER S, OF CONCORD, NEW HAMPSHIRE,
IMPROVEMENT IN DEVICES FOR PREVENTING CHIMNEYS FROM SMOKING.
Specification forming part of Letters Patent No. 188,497, dated March 20, 1877 application filed To all whom it may concern:
Be it known that I, JOSEPH R. BOWERS, of Concord, in the county of Merrimack and State of New Hampshire, have invented a certain Device for Preventing (Jhimneys'from Smoking, of which the following is a specification, reference being had to the accompanying drawing illustrating the same.
My invention is intended to provide a simple and eficient means of assisting the draft of chimneys so as to prevent their smoking; and it consists in placing upon the top of the chimney a horizontal pipe or tube, which communicates below with the flue or flues of the Ghllnllfijflfiild at each end with vertical tubes, as hereinafter more fully described.
Figure 1 is a perspective view of the device as applied to the chimney, and Fig. 2 is a view of the same detached.
a represents a horizontal tube or pipe, se-
cured upon the top of the chimney by suitable December 18, 1876.
vertical tubes are made of various sizes, ac-
cording to the size of the flues in the chimchimneys situated under the lee of taller structures, where vertical currents of air may be generated, which would blow downward into the chimney, such vertical currents will pass into the open upper ends of the tubes b b, and be conducted past the ends of the horizontal tube a, and out at the lower ends of the tubes b I), thus tending to assist the draft of the chimney, rather than obstruct it, upon the same principle by which air may be exhausted from a tube by passing a jet of steam by the open end thereof.
I claim as my invention The combination of the vertical tubes 1) b, open at both ends, with the horizontal tube or pipe (1 having a downward projecting flange or casing, 0, when applied to the tops of chinr neys, as and for the purpose set forth.
JOSEPH B. BOWERS.
