Patented May 23, 1933 PATENT `OFFICE JOHN AJEMIAN, OF DETROIT, MICHIGAN VENTILATOR Application led May 27, 1930. Ser'ial No. 456,003.
My invention relates to a new and useful improvement in aventilator adapted particularly for use on stoves and in connection with canopies positioned over stoves, although from the construction of the fan or draft producing mechanism it will be apparent that the structure may also be used for Ventilating purposes generally. It is an object of the present invention to provide in a canopy positioned over a stove, an auxiliary support or shelf which may be, when .the same is not used, swung inwardly of the canopy and substantially concealed from view.
Another object of the invention is the provision in connection with a canopy of a concealed draft producing means which will assist in the expelling of vapors and odors arising from articles being cooked on the stove. l
Another object of the invention is the provision in a draft producing means of a regulating damper whereby the draft produced by the mechanism may be regulated and this to a line degree.
Another object of the invention is the provision of a device of this class which will be simple in structure, economical of manufacture,` and highly eflicient in use. i
Other objects will appear hereinafter.
The invention consists in the combination and arrangement of parts hereinafter described'and claimed.
The invention will be best understood by a reference to the accompanying drawing which forms a part of this specification and in which, i

In the drawings I have illustrated the invention used with a stove 12. A canopy 13 is positioned over the stove and provided with an outlet flue 15 connected with the usual oven flue 15. A shelf 16 is provided and has a groove 15 formed in its end edges into which project screws 14 extending through the end walls which project forwardly from the back 21 of the stove. The mountings of the shelf at opposite endsv of the canopy are similar so that a'description of one side will sullice for both. Secured to the under surface of the shelf 16 at opposite sides is a depending lug 17 to which is pivotally connectedan arm 18 which is also pivotally connected to the arm 19 which is pivotally mounted on the end wall 20, these arms serving as a toggle. When the shelf is moved to outward or operative position, as shown in Fig. 2, the arms 18 and 1 9 are in the position illustrated in full lines. A fiange 16 is mounted on the rear edge of the shelf 16' to prevent outward movement of this shelf and a flange 16'. projects upwardly from the front edge ofthe shelf 16 to serve as an abutment when the shelf is swung to inward or inoperative position. Positioned in the flue 15 is a cylindrical support 22. A diametrically extending bar 23 is secured to the support 22 at its upper end and projected centrally through the bar 23 is the screw 24 provided with the lock nuts 25 and having formed on its inner endfthe recess 26. A screw 27 is provided with the lock nuts 28 and the conical seat 29 at its inner end is projected through the diametrioally extending supporting bar 29 which is secured to the inner surface of the cylindrical support 22 adjacent its lower end. The screw 27 is in alignment with the screw 24 and these screws serve as a support for the axle 30 of the fan. Blades 31 project radially outwardly from the axis and are secured at their outer ends by the cncircling band 32.
' succeeding section with it.
34 adapted to engage the outwardly bent,
tongue on its adjacent section 48. An
upwardly bent tongue 38 is formed on the l section 33. rlhe construction is suchv that the,
sections 48 may be swung into over-lying position relatively to the section 33 thus opening the supporting member 22 and permitting passage of vapors through the outlet flue 15. By rocking these sections on the screw 27 as a pivot, the lopening into the support 22 may be closed or reduced in size. Each section, through the engagement of its tongue 34 Vwith the tongue 35 of the next succeeding section serving to drag the next The tongue 38 on the section 33 serves as an abutment for the end section 48 when these sections arepin closing position. In this way the escape of vapors may be controlled withoutproducing any excessive draft in the lroom in which the stove is positioned. y
The end-most of the swingably mounted sections 48 is provided with an outwardly projecting handle 36 on which 1s attached one end of each of the chains 103 and 104 which slide in the channels 105 formed by the band 106. These chains extend around rollers 107 and 108 respectively and project beyond the channel. A pulling on the chain 104 will move the sections 48 into overlapping relation to open lthe ventilator and a pulling on the chain 103 will move these sections to closing position.
In Figs. 9 and 10 I have shown a slightly different form of control mounted on the draft producing member. A cylindrical support 38 is adapted to be mounted on the outlet flue 15 as described for the support 22. Projecting diametrically across one end of the support 38 is a supporting bar 39. The support 38 is closed by a pair of semi-circular dampers 40 and 46. A rod 41 extending diametrically of the supports 38 serves as a hinge for the damper section 40, one end of this rod being angularly turned to provide the operating handle 42. The outer endV of the rod 41 is angularly turned, as at 43, to engage the eyelet 44 which is formed by the angularlyv turned end of the rod 45 on which the damper section 46 is fixedly mounted. The construction is such that by rocking the rod 41 these damper sections may be moved to closed position, as shown in full lines in Fig. 10, or to opening position, as shown in dotted lines in Fig. 10.
Supported upon the bar 39 is a boss 47 against which engages one end of the rod 30 which carries the blades 31 connected by the band 32 the opposite end of the rod 30 engaging a screw such as the screw 27 shown in Fig. 5. It is believed obvious that the ventilator construction shown embodying the fan and the mountings therefor may also be used for Ventilating purposes generally and need not, of necessity, be limited to a stove ventilator. t
While I have illustrated and described the preferred form of my invention I do not wish to vlimit myself to the precise details of structure shown but'desire to avail myself of such variations and modifications as may come within the scope of the appended claims. j f
`IIa-ving thus described my invention, what I claim as new and desire to secure byuLetters Patent is: l
1. In a device of the class described: a cylindrical supporting member; a pair of bars, one of said bars being mounted in each end of saidY supporting member and extendingy diametrically across the same in alignment with each other; a screw projecting inwardly through each of said bars centrally thereof in alignment with each other; a Ventilating fan; a central axle for said fan engaging at opposite ends the opposingy faces of said screws and rotating thereon; a closure-.for one end of said supporting member comprising a plurality of sections each of said sections being swingably mounted on one of.
said screws outwardly of the bar through which the screw is projected.
2. In a device of the class described: a sup'- porting member, a pair of bars, one of -said bars being mounted at each end ofsaid supporting member and extending dia1netrically thereacross; a screw projecting through each of said bars at the center thereof, said screws being in alignment andv each having a recess formed in the opposing faces; a ventilating fan; an axle for said fan having its opposite ends tapered and engaging in the recess in said screws for vrotatably mounting said fan thereon; a closure for one end of said supporting member comprising a plurality of sections each swingably mounted on one of said screws outwardly of the bar through which the screw is projected; a guide member carried by said supporting member; and a flexible member guided-by said guide and operatively connected with the sections of said closure for moving the same to open and closed position. 1
In testimony whereof I have signed the foregoing specification.
JOHN AJEMIAN.
