Description

.A. B. ANDERSON VENTILATOR AND THE'LIKE Oct. I 1
Filed June a, 1925 Patented Get. 11, 1927.
UNITE STTES E T .FHCE- ALFRED B. ANDERSON, OF NEW HAVEN, CONNECTICUT.
VENTILATOR AND THE LIKE.
Application filed June 6, 1925. Serial No. 35,337.
a simple and efficient device by means of which proper ventilation is obtained when used as a ventilator, and when used as a w chimney top an induced draft is created and maintained.
In carrying out the invention, the improved device consists of a structure of a suitable size and shape composed of suitable 1:; material, preferably sheet metal as shown in the several embodiments of .the invention illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of the im proved device constructed in accordance with the invention, and applied to a chimney to a.
Figure 2 is a vertical longitudinal section of the improved device, and Figure 3 is a vertical section showing a modified means for securing the device in a position for operation.
Referring to the drawings, the improved structure consists of a rectangular or other suitably shaped casing 1, having a flanged base 2 which is adapted to be seated on the top of the chimney such as 3 and secured in any suitable manner. The casing 8 has a roof or canopy 4 over the top thereof and said canopy is supported by rods 5 which are secured to the casing in any suitable manner. The canopy & hangs over the top of the open casing and is located so as to leave a space 6 therebetween. The overhanging sides and ends 7 of the canopy cover the flue 8 of the casing 1, and this flue communicates with the flue in the chimney 8. A number of perforations 9 are provided in the casing near the upper end thereof. These perforations are covered against direct admission of air by lower baifle or deflector plates 10 ar ranged on all sides of the casing 1. The said plates are composed of a band secured around the casing in any suitable manner and said plates are arranged in an angular position relatively to the casing. Upper plates 11 arranged in an angular position, slanting upwardly instead of downwardly as in the case of the other plates 10, provide deflectors the same as the lower plates,'and
said upper plates serve to prevent downward or back draft into the flue of the casing. Near the bottom of the casing on all sides orifices 12 are provided and these orifices admit a'current of air which enters the flue at a lower point and mixes with the air rising in the flue, whereby an induced draft is created to cause the device to operate more effectively as a ventilator or the like.
In Figure 3 a slight modificationis shown in which case the casing is cut out at the lower end to form ears 13 extending at right angles to the casing and vertical ears 14 which extend downwardly into the flue.
the top of a chimney in the course of erection of the latter. Furthermore, this latter means of securing the device may be used when the ventilator is to be secured to the top or sides of a vehicle such as railway cars or the like.
It will be understood in the operationof the improved device that rain or snow, and even dust or grit, to some extent, is prevented from entering into the flue of the device. The arrangement of air admission orifices and deflectors is such that the outside current of air will be diverted from. blowing downwardly through the flue. Instead. the current of air from the outside is directed upwardly and mingles with the air rising up through the flue, thereby, as previously stated, an induced draft is created.
Various modifications in the construction and application of the improved device or means heretofore described may be made without departing from the spirit of this invention, and it is intended that any modification coming fairly within the terms of the claim shall be covered thereby.
I claim:
In a ventilator of'the class described, a casing forming a single flue, said casing having an open top; deflector plates adjacent to and surrounding said open top on all sides; said plates being added memberssecured to said casing and arranged so as to lie in opposite angular positions relatively to each other and a series of holes in said casing beneath said deflector plates, substantially as and for the purpose set forth.
Signed at vNew Haven, county of New Haven, State of Connecticut, this 18th day of April, 1925.
ALFRED B. ANDERSON.
By these means the ventilator may be secured to
