Description
Patented June 16, 1931 UNITED STATES JOHN F. JEWART, OF BLASDELL, NEW YORK VENTILATING STOVEPIPE Application filed April 10,
This invention relates to stove pipes, the primary object of the invention being to pro vide a stove pipe which will act as a ventilator to cause the impure air of the room in '5 which the stove pipe is positioned, to pass off through the chimney.
An important object of the invention is to provide a stove pipe having a horizontal open ended section and hinged closure for closing the open end, means being provided for holding the closures in their closed positions.
Another object of the invention is to provide closures that will automatically move to their closed positions when a back or down draft occurs in the chimney, thereby assuring against soot and smoke being blown into the room.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departin from the spirit of the invention.
lReferring to the drawings:
Figure 1 is an elevational view of a stove pipe constructed in accordance with the invention, a portion of the pipe being broken away to illustrate the closures. 7
Figure 2 is an end elevational view thereof.
Figure 3 is a sectional view taken on line 3-3 of Figure 2.
Referring to the drawings in detail, the chimney comprises the usual vertical section 5 that has connection with the stove proper, and a horizontal section 6 that connects with the chimney 7. The horizontal section 6 has one end thereof extended beyond the pipe 5, as at 8, the front end of the extension 8 being normallyopen and closed under abnormal conditions, by means of the hinged closures 9 that have curved outer edges to conform to the shape of the pipe section 6.
' Flanges 10 are formed at the end of the ex tension 8 and provide stops for the hinged closures 9. The closures 9 are connected 0 with the bar 11 that extends vertically across 1930. Serial No. 443,148.
the end of the section 8, the her being pro- 7 vided with an-opening disposed at a point intermediate its ends for the reception of the shaft 12 that extends therethrough. Secured on the inner end ofthe shaft 12 is a bar 13 that has curved extremities 14 curved in such a way that they will contact with the rear surfaces of the closures 9, the curved portions cooperating with the circular enlargement 15 formed on the shaft 12, in exerting a pressure against the closures 9, to hold them in their closed positions when the bar 13 has been turned to a position transversely of the closures, as clearly shown by Figure 3 of the drawings.
' An operating handle 16 is formed at the forward end of the shaft 12 and affords means whereby the bar 13 may be moved to allow the closures to swing to their open positions, or to move the closuresto their closed positions. Under normal conditions the bar 13 is moved to a position as shown by Figure 1, where it lies parallel with the bar 11, allowing the closures 9 toswing inwardly so that air from the room may pass through the section 6, and into the chimney 7-so that impure air in the room may be disposed of.
The reference character 17 designates a damper which is of the usual and well known construction, the damper being of a diameter T to completely close the extension 8 of the pipe 6, when the damper is turned at right angles to the position as shown by Figure 1, so that the air passing through the pipe section 6 may be regulated to meet various require-' ments.
It might be further stated that the closures 9 are of such constructions that they will swing freely on their hinges, to the end I that should a down draft or back draft occur, the closures 9 will be swung to their closed positions as shown by Figure 3, preventing smoke and soot from being blown into the room by such down or back draft. 1
From the foregoing it will be obvious that due to the construction shown and described, the usual chimney and stove pipe may be utilized for carrying off impure air which col lects near the ceiling of the room, without the danger of smoke and soot being blown into the room by down or back draft in the chimney.
It might be further stated that the 010- sures are mounted in such a Way that they will swing freely, to the end that the draft up the chimney Will cause the closures to swing to their open positions.
I claim:
' A stove pipe Ventilator comprising abody portion embodying a pipe to be connected with a stove pipe, a closure for closing one end-of the body portion, a bar extending across one end of the body portion, said closure embodying a pair of sections connected with the bar, a shaft extending through the bar, across bar on the inner end of the shaft and :adapted to engage the sections to move the closure to its'closed position, and the said bar having curved portions adjacent to the ends thereof to exert a pressure on the closure. 7
In testimony that I claim the foregoing as my 'oWn, I have hereto aflixed my signature.
JOHN F. .JEWART.
