KITCHEN VENTILATOR.
Application filed March 18, 1925. Serial No. 16,336.
To all whom it may concern Be it known that VVALTER H. ANDERSON, a citizen of the United States, residing at San Rafael, in the county of Marin and State of California, has invented certain new and useful Improvements in Kitchen Ventilators, of which the following is a specification.
My invention pertains principally to a kitchen ventilator constructed to be form-ed with part of the smoke pipe from a stove or the exhaust gas pipe from a gas stove. The objectis principally to exhaust the air from the kitchen and blow it out the chimney, but the blower may also function to give increased draft to the fire when this is desired.
My specific construction illustrated herein shows a 'T' junction of a smoke pipe with a horizontal lead pipe to a chimney or wall flue and an electric motor mounted in the open end of the T to draw air from the kitchen. This T junction is preferably supported from the ceiling by a pair of hollow tubes which form the conduits for the electric leads to the electric motor from a conveniently placed hand switch. The T junction has a curved baffle plate in order to divert the air from the fan so that it may act on the ejector principal and draw the smoke upward from the stove instead of blowing it downward. A damper of the butterfly type is shown in the up-take part of the T junction and another butterfly valve in the horizontal section to shut ofi the outlet to the kitchen when the fan is not in operation. The fan is so mounted in the T junction pipe, that it may readily be removed and if desired, can be turned in the reverse direction in order to function as a circulating fan for the air in a room.
My invention will be more readily understood from the following description and drawings, in which:
Figure 1 is a section in a vertical direction through my T junction smoke pipe, with the ventlating fan mounting showing the installation with a stove and smoke flue.
Figure 1 shows a stove or range A, uptake P smoke pipe B, T junction ventilator C, horizontal smoke pipe D, chimney flue E and ceiling F.
The T- junction pipe C has an enlarged horizontal portion 1, and a reduced portion 2 leading to the horizontal smoke pipe D, and an inlet 3 in which is installed the electric motor, as will be hereafter described. The junction pipe 4 is seamed or riveted at 5 to the horizontal portion 1 and has the usual depressed beading 6 to engage the uptake smoke pipe B. A damper 7 of the butterfly type is preferably inserted in the junction pipe 1-. A curved baflie plate 8 is riveted to the pipe 4, and forms a partial arch, directing the air from the fan.
The electric motor and fan is mounted as follows:
A ring shaped rim 9 has a series of spider arms 10, to which is bolted an ordinary electric ventilating motor 11, having a shaft 12, on which is mounted the fan blades 13. Thus the rim, spider and fan may be regarded as a separable unit. The inlet 3 of the junction pipe is curved as shown at 14 in order to engage the rim 9, and is shown having a split portion 15 at the top and bottom, with lugs 16 on opposite edges thereof, through which bolts 17 are secured to draw the split portions 15 together, and thereby clamp the rim 9 and securely hold the motor in position. By this construction, the motor may be easily removed for cleaning and oiling or the like, or to clean out the junction pipe; and it may also be reversed so that the fan may function as an air circulating fan in the room.
A butterfly valve 18 mounted on a horizontal shaft 19 is secured in the horizontal portion 1 of the T junction pipe, and swings cross-ways to engage the baffle plate 8, thus shutting OK the inlet from the kitchen.
The T' junction pipe is supported from the ceiling F by tubes 20, which preferably have a screw threaded connection to brackets 21 secured to the ceiling, and are fastened by clamp screws 22 to each side of the horizontal portion 1. These tubes 20 form conduits for the electric leads 23, which extend down the wall as shown at 24, to a conveniently placed hand switch 25. The tubes have openings 26 for the entrance and outlet of the electric leads. It is, however,
preferable to have the Wiring concealed and pass from the ceiling directly into the tubes 20.
The manner of use of my kitchen ventilator is substantially as follows:
If no ventilation is required, the butterfly valve 18 would be closed, however, if it is desired to ventilate the kitchen, this may be opened to any desired degree, and the fan started. The battle 8 directs the air from the fan upwardly, thus preventing it blowing down the smoke pipe B. This action also tends to increase the draft, and in. fact may be used as a forced draft for the stove. As above described, the fan may be reversed if required for circulating the air in the room.
Having described my invention, what I claim is 1. A kitchen ventilator comprising in combination. a stove pipe, a flue, a horizontal pipe crossing the stove pipe and leading into the flue, and a motor driven fan mounted in the horizontal pipe on the inner end.
2. A kitchen ventilator comprising in combination a stove pipe, a flue, a horizontal pipe crossing the stove pipe and leading into the flue, and a motor driven fan mounted in the horizontal pipe on the inner end, with a baffle at the joint diverti-ng the blast from the stove pipe.
3. A kitchen ventilator comprising in combination a stove pipe, a flue, a horizontal pipe crossing the stove pipe and leading into the flue, a spider mounted in the inner end of the horizontal pipe and having a motor axially supported therein and a fan on the motor shaft adapted tosend an air blast through the horizontal pipe into the flue.
4. A kitchen ventilator comprising in combination a stove pipe, a flue, a horizontal pipe crossing the stove pipe and leading into the flue, a spider mounted in the inner end of the horizontal pipe and having a motor axially supported therein and a fan on the motor shaft adapted to send an air blast through the horizontal pipe into the flue, the spider being :removably and reversibly mounted on the pipe.
5. A. ventilator comprising a T junction pipe having an enlarged horizontal ventilating pipe, a smaller vertical products of combustion pipe, a batiile between the two pip-es, a damper in each of the two pipes, and an electric motor secured in a bell shaped opening in the horizontal pipe, said. opening allowing readily removing of the motor, and a fan directly connected-to the electric motor.
6. A ventilator as claimed in claim 5-, in which the bell shaped inlet to the horizontal pipe is split, and the electric motor is mounted in a ring having spider arms connected to the motor, and clamping bolts to secure the ring in the split part of the opening.
In testimony whereof I affix my signature.
lVALTER H. ANDERSON.
