Description
Patented Aug. 30, 1932 CHARLES v. COLVIN AND 3101mm) ros'imn; orrLnn'smo, ncrementi- KITCHEN Application filed September 12, f SeriaIYNo. 481, 35
This invention relates to ventilators, more particularly to apparatus including a fan and motor whereby the fan is driven, which are arranged upon or in some manner associatecl with a hood or canopy in kitchens.
' Air and fumes are drawn by the fan into the hood and exhausted therefrom by way of a suitable uptake or outlet leading to the exterior of the building.
The object of this invention is the production of such construction having parts of special formation and disposition and intended to be applied to a hood which constitutes the base or bottom of a compartment f which is plastered on the outside in the same manner as the ceiling and walls of the room, and the arrangement with respect to the hood being so made as to permit the motor and fan to be removed downwardly through the hood for inspection or repairs without disturbing the hood or breaking any plaster.
In the accompanying drawing is illustrated one combinationof the parts comprising this invention and Fig. 1 shows all the parts assembled with this invention applied to a hood. Fig. 2 represents the top of the hood with all other parts removed, and illustrates the opening in the top. Fig. 3 is a top view of the fan casing only.
Throughout the drawing and description the same number is used to refer to the same part.
Considering the drawing, the ceiling 1 of the room has extending downwardly a frame 2 by which is formed a chamber designated as a whole by the numeral 3. The chamber is plastered and white coated on the outside and around an opening in its bottom to preserve the appearance of the room. In the below the opening 6 is 'attached a plate 7.-
The plate may bedetached from the hood,
opening in the bottom of chamber 3 is sethe plate has an "opening or I8.
Upon the plate 7' is located a fan casing 9 'which is made with an openingvor openings 10 in its bottom arranged to register j'witlr'the 3 r 'openingsfoff the y y y y casing Jupon the bottom thereof is a rotatable damper plate 112 operated by means otfthe handle 13. "The: damper; plate is not ess ti'a'l, but is advantageousundercertaineircum'stances set out thefstatement of operation.

motor may be protected by mover 18 1761 63 ablyfs'ecur'ed to' tha late 17. This intrantion is in no way limited as to the character fsi'ze tor structure olffthe motorand 'fan elements." The motorimay be conn cte'dfbjy 7o conductors 19 and 20 withf'a wallifsw ch21 of 'custoinary pattern i Asset out in Figs l 3, the fan casing has the usual tangential dutlet 22, and this is 1;, introduced lor'a "sh'ortdistance into the elbow 5 .23 of an outlet conduit which may pass upwardly through the ceiling 1 and to the outside of the building.
It is believed to be within the purview of :25,
this invention to employ the hood in any 30 7 position with or without the plastered chamher 3, and the particular shape of the hood is not important.
In explaining the operation of this inven- 32:- tion, attention is called to the fact that as 35 illustrated in Fig. 1 the fan casing 7 is located at one endof the opening 6 of the hood when the outlet 22 is introduced into the elbow 23. Now, if the plate 7 is detached, the fan casing may be moved to the left hand and the outlet 22 will be withdrawn from the elbow 23. This procedure permits the fan casing and motor to be tilted and with :a little care the motor andfan may be passed downwardly through the opening 6 of the hood.
The fan and motor are replacedby contrary discharged by the fan, and the volume of the entering the fan may be controlled by the damper plate 12; If the entrance openings into the fan are wide open and the fan is operated at sufiicient speed, the air may be drawn from the entire lower floor or upper floors, and
in this way the air may be changed throughp out a dwelling by means of the Jsingle ventilating devices herein shown and described. Having now described this invention, and explained the manner of its'use, We. claim 1. In a ventilator, the combination with a hoodhaving an openingin the wall thereof,
" of a fan and motor'therefor, a fan casing having an outlet pipe, an air conduit, the said, outlet pipe constructed to be-removably inse'rtedin'said air conduit, the said motor and fanbeing supported upon the hood in detachable relation thereto, saidmotor and fan casing being removabletogether through said, opening in the hood thereby withdrawing said outlet pipe from said conduit.
I 2. In a ventilator, the combination with a I hood havingan opening in the wall thereof, of a fan and motor therefor, a fan casing 7 having a tangential outlet pipe projecting horizontally at one side, an a air conduit, the
said outlet pipe and conduit being respectivelyconstructed and arranged whereby the outlet pipe may be removably inserted into :said conduit, the said motor and fan casing be ng supported uponthe hood in detachable relation. thereto, said motor and fancasing being removable through the said opening in the hood thereby from said conduit.
In testimony tures.
