AIR DIFFUSER AND REGULATOR.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application led August 16, 1918. Serial No. 250,191.

To all whom t may concern j j Be it known that I, FRANK A. A. BARRS, a. citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Air Diffusers and Regulators, of which the following is a specification.

This invention relates to a means for controllingthe admission of air for ventilation into a room and for directing and diffusing the air as admitted.

In any Ventilating system where heated or cooled air is delivered into a room, unless some means is taken to upwardly direct and diffuse the inpassing air, objectionable draft is experienced inthe line of the delivery, while there may be stagnation of air in other parts of the room.

The invention, which is the subject of this application, is designed to avoid these objections by providing the air delivery inlet to the room with a means not'only for controllingr the amount of air admitted but for directing and diffusing the inflow.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a vertical section through the air register and diffuser on the line 1-1 in Fig. 3.

Fig. 2 is a face view showing the connection of the operating means to the air directing planes. Fig. 3 is a plan on the line 1, and

Fig. 4 is a plan of the rope operated nut by which the directing planes are set and 3 3 in Fig.

held at anyl desired angle and of the yoke is divided by partitions 5 into a series of separate outlets 4, and these partitions are Carried a suilicient distance into the duct 2 below fthe delivery aperture to insure reasonable uniformity of ow through the several divisions of the duct.

The partitions 5 of the delivery aperture are preferably disposed horizontally and each subdivision has a closing and iniow directing plane 6 pivotally mounted at 7 in the front edge of each side of the frame 3 in line with the underside of the subdivision aperture 4 and closable upward against stops 8 projecting from the inner side of the outlet frame.

The pivots ofthe inflow directing planes are retained in position by cover strips 27 secured over them to the edge of the frame 3. These inflow directing planes may be set at any desired angle in relation to the plane of the wallv 9- and may be closed against the stops 8 by a link rod 10' which is pi-votally connected to a spur lever 11 backwardly and upwardly projecting from the pivot edge of each plane 6 adjacent its midlength. The lower end of this link lrod 10 is pivotally connected at 29 to the end of a screw 12, on which screw is threaded as a nut a rope sheave 13. This nut sheave is rotatably mounted between bearings 14 in a yoke 15 which is provided with trunnion pins 16 on which the yoke is carried in brackets 17 secured to and downwardly projecting from the underside of the outlet frame 3.

This trunnion mounting of the nut carrying yoke 15 allows the nut sheave 13 to adjust itself to the angular movement of the -screw 12. The brackets 17 also carry the pins 18 on which small rope guide sheaves 19 are mounted, around which sheaves an endless operating rope 20 is conducted from the pendant vertical line of the rope to the horizontally disposed groove of the nut sheave 13. By placing the guide sheaves 19 back of the nut sheave 13 the rope 20 is more effectively retained on the sheaves, but a guard 29*l may be carried around the front of 13 to prevent accidental displacement of the rope.

By this manner of mounting, the nut sheave 13 may be rotated in either direction by the endless rope 20, and, being heid against endwise movement, will, through the agency of the screw 12, raise or lower the link rod 10 to close or set all the planes 6 to any desired angle and will support them as set.

Secured to and projecting forward from the upper side of the outlet frame 3 at a slight upward angle is a hood or canopy 21, which prevents the upwardly directed current of air from being projected against the ceiling. The air delivered into a room may thus be controlled in amount and directed Lateral diffusion of the air currents so delivered from each division of the air admission is effected by a series of diffusing 'vanes 22 secured to and upwardly projecting from each plane 6. These vanes are flanged along the lower edge where they are secured to the planes and the upward and the forward edge is substantially concentric with the ypivotal mounting of the planes 6 that the vanes will freely pass within the division of the delivery aperture.

These lateral diffusing vanes 22 are piv-A otally connected atv 23'to the back or pivotal edge of each plane 6 and are secured in any desired position of angular adjustment by a clamping bar 24, which passes through an elongated aperture 25 partially sheared in each vane and the partially sheared portion downwardly turned to the side opposite the flange, on which flange and downwardly turned portion-the bar 24 may be clamped .to secure the vanes-by a small bolt 26 at each end of the bar and lintermediate of the same.

These three bolts of the clamping bar may be slackened and the vanes set at any desired angle to either or both sides .and se- 4 cured. This setting and clamping of the lateralv diffusing vanes are. supposed to be done by one who knows the ventilation vrequirements of the room.

By dividing the {iow of air delivered to a room and by controlling the direction of the divided flow upward 'or downward and by v'laterally diffusing it, the ventilation `of a plished, and -while I am aware that prior to room may be much more efectively accom- .my invention the admission of `air for the heating or ventilation of'a room has been controlled by a register having narrow pivotally mounted louvers or shutters, which may have had the effect of directin the'low to some extent, I am notaware o any system wherein-the inow has been divided, di-

. .rected and diffused as by the devicehereinbefore described.

Having now particularly described myim ve'ntlon, I hereby declare that what I claim protected in by Letlaterally directing vthe low'of the admitted air.
