BENJAMIN B. LEWIS, OF BRIDGEPORT, CONNECTICUT.
CHIMNEY-TOP DRAFT-REGULATOR.
SPECIFICATION forming part of Letters Patent No. 594,257, dated November 23, 1897.
Application filed May 27, 1896. Serial No. 593,358. (No model.)
the purpose of obtaining a better and more reliable draft for the heating apparatus connected with the same.
More specifically, my invention pertains to that class of chimney-tops terminating with a cap of stone and under which openings are left on its several sides communicating with the flue or flues of the chimney and is intended to guard against the failure of draft often experienced in chimney-tops thus constructed when a strong wind is blowing directly against one of its sides. Under such circumstances the momentum of the air thus driving directly against the flue opening serves to create a pressure within the chimney-top, which in turn relieves itself in part by an expansion downward, thus at times reversing the natural upward draft of the chimney. The apparatus employed by me for this purpose is that of a flue-opening shield having an exterior face approximately of the size of the flue-opening and removed to such a distance from the exterior face of the chimney as to allow the passage of smoke and gases between it and the edge of the stone cap above and the side of the chimney beneath and being supported by side pieces extending into and forming side linings of the flue-opening or by some other suitable form of attached arm passing into the flueopening.
In the accompanying drawings, Figure 1 is a plan view of a chimney-top supplied with the flue-opening shield, the cap having been removed. Fig. 2 is an exterior elevation of the same with cap.
In the plan view Fig. 1, A A:A A are the elevated portions of the chimney-wall, upon which rests the chimney-cap.
O O O O are flue-openings directly beneath the chimney-cap.
D D D D are the flue-opening shields at such distance from the face of the chimney as to leave openings both above and beneath for the passage of smoke and gases.
E E are supporting side pieces extending within the flue-opening. In three of these flue-opening shields two interior flanges H H are shown and also two exterior flanges K K. The action of these flanges upon the outward sides of the supporting-arms of the flue-opening shield is that of holding it in a fixed position within the flue-opening. In two of these flue-opening shields a reversible clamp L is shown, having side arms pivoted to the shield at the points M M. The interior ends of the side pieces E E of the shield are shown bent inward to allow of the passage of the interior flanges H H of the shield within the flue-opening when placing it in position. In the other two of these openings the clamp L is shown in a reversed position to that previously shown, having been turned a half-revolution upon its pivoting-points M M, thus bringing it within the flue-opening and pushing outward and holding in an approximately straight line the interior parts of the supporting side pieces E E.
When a flue-opening shield provided with the reversible clamp, as shown, and also having the interior flanges H H is to be applied to a flue-opening, the bar connecting the pivoted side arms of the clamp isv first turned outward toward the face of the shield, and the ends being bent inward are thus passed within the flueopening. The bar of the clamp L is then turned a half-revolution upon the pivoting-points M M, thus pushing outward and clamping securely in place the interior parts of the supporting side pieces E E.
It is evident that the exterior shield protecting the flue-opening may be held in place when preferred by a framework of attached metal rods or any suitable form of supporting-arms passing into the flue-opening.
What I claim is- 1. In a chimney-top, the combination of a stone cap B and a flue-opening shieldD,whose supporting sides E, E, constitute side linings of the flue-opening, substantially as shown.
2. In a chimney-top, the combination of a stone cap B, and a flue-opening shield D having supporting side's E, E constituting side linings of the flue-opening, and having interior flanges H, H, substantially as shown.
3. In a cl1imney-top, the combination of a stone cap B, and a flue-opening shield D having supporting sides E E constituting side linings of the flue-opening with interior flanges H, H, and exterior flanges K, K, substantially as shown.
at. In a chimney-top the combination of a 10 stone cap 13, and a flue-opening shield D having supporting side pieces E, E, constituting side linings of the flue-opening, having interior flanges H, H, and exterior flanges K, K, and having also a reversible clamp L, substantially as shown.
