Iam INLET,

Application iled September 22, 1926. Serial No. 137,152.

This invention pertains to ventilators and more particularly to ventilators of the type used in theatres-and auditoriums and placed beneath the seats for dispensing warm or One of the objects of this invention is to provide a ventilator of simple and rugged construction and which may be easily adjusted to regulate the passage of air there- Another object is to provide such a ventilator which may be adjusted and whose adjustment is not easily. tamperedy with.

Further objects will appear from the following description taken in connection with the accompanying drawing in which:-

Figure 1 is a perspective view illustrating the manner in which the ventilator may be placed beneath the seats in a theatre; Figure 2 is a longitudinal section of a ventilator embodying this invention;

ligure 3 is an end elevation of the same, an

Figure 4 is a detail illustrating another embodiment of this invention. y

Referring to the accompanyin drawing 1 designates a casing which may e formed with vertical sides 2 and an arched roof 3. The ends 4fof, thecasing are open except that a Screen 5 of wire mesh or similar material is mounted therein to prevent the entrance linto the ventilator of scraps of paper and similar litter which ordinarily accumulates on the floor of a public place.

The bottom of the casing 1 1s open and may be provided with a marginal flange 6 adapted to it into an opening in the" floor 7. Side or end flanges 8 may be arranged to rest on top of the floor and provided with means such as screws 9, for fastening the same to the ioor. The sides 2 may be provided with flanges 23`welded or otherwise secured to the flange 6.

At the middle of the bottom opening of the casing a pivot bar 10 spans the opening and Has hinged thereto a pair of dampers 11. The dampers 11v are connected by' links 12 to the wings 13 of a win nut 14 threaded on to a-screw 15 swivele 55 shown inthe full lines in Figure 2 t e ventilator is closed and the passage of air therep in'a lug 16 on4 I 6o the roof of the casing and extending downthrough is eut oil'. By inserting a screw driver or similar tool into the head 17 the screw 15 may be operated so as to raise the nut 14 and lift the dampers. The dampers are shown in openposition in 'dotted lines in Figure 2. The dampers may be set in any intermediate positionbetween fully open position and fully closed. Thus the air through the ventilator may be controlled and, therefore, the distribution of air Ato different parts of the auditorium may beregulated. When the dampers 11 are in closed position they may be arranged to rest upon internal flanges 18 mounted in the casing.-

In 'the embodiment of Figure 4, the nut 13 has its wings extended, and provided at the ends of the wings with inclined cam slots 20. Each of these slots is slidably engaged by a headed pin 21 on a bracket 22 Xed to the upper side ofone of the dampers 11. Vhen the nut is raised by the screw 15 the dampers will beraised thereby,

the pins 21 sliding along the slots 20, as-

shown in Figure 4. y

The end vscreens 5 may be mounted in any suitable frames 19 which frames are then mounted in the ends ofthe casing. l

It will be seen, therefore, that this invention provides a simple and eective ventilator which, having its dampers pivoted at the middle of the casing distributes the air in two directions therefrom. The dampers may be accurately adjusted to any desired opening. and both dampers are adjusted simultaneously-to the same opening. The adjustment requires the use of a tool fitting the head 17 so that such adjustment cannot ow of.

easily be tampered with except by a proper attendant. y

It is obvious that various changes may be made in the details of construction without departing from the spirit of this invention; it is to be understood, therefore, that this invention is not to be limited to the specific details shown and described.

Having thus described the invention what is claimed is:

1. A ventilator, comprlsin a casing having an open bottom adapte to lit a floor .opening and having .o en ends, a pair of dampers pivoted in sai casing at the middle ofthe bottom thereof, and a single means forv simultaneously adjusting vsaid dampers on said pivot. o,

2. A ventilator, comprisin a casing having an open bottom adap to fit a iloor opening and having open ends, a pair of dampers pivoted in said casing at the middle of the bottom thereof, and means operable by a too1 for nslmultaneously adjusting'said dampers on said pivot.

3. A ventilator, comprising,-a casing having an open bottom adapted to t a floor I opening and having open ends, apair of dampers pivoted in said casing at the'middle of the bottom thereof, a screw operable from outside of said casi-ng, a nut for said screw, and connections from said nut lto said dampers adapted for simultaneously adjusting said dampers on said pivot.

4. A ventilator, comprising, a casing hav- 15 ing an open bottom adapted tot a Ifloor opening and having' open ends, a pair of d'ampers pivoted in said casing atl the middle `of the bottom thereof, a screw operable from on said pivot. v

In testimony whereof I afix my slgnature 25- this 4th day of December,1925.
