DEFLECTOR- FOR VENTILATING SYSTEMS.

Application filed May 27, 1927. Serial No. 194,622.

This invention relates to in'iprovenients in deflectors for ventilating systems and it consists the matters hereinafter described and more particularly pointed out in the appended claim.

In the auditoriums of theater buildings and other places of public gathering, the arrangement of the deflector casing for the discharge mouth of the ventilating system presen s a somewhat difficult problem due to its appearance which does not harmonize or fit in with the wall furnishings and decorations usually found in such places. Ordinarily such months are either covered with a grille or the months are placed in an out of the way position, both of which detracts from the most efficient operation of the ventilating system.

The primary object of the invention is to provide a deflector arrangement which may be placed in a richly furnished or ornamented wall and which no matter from what angle the same is viewed, will it detract from the appearance of its surroundings.

A further object of the invention is to provide such a deflector wherein the blades thereof are pivoted at the front of the casing so as to present to view only the front edge thereof; the remaining portion of the blades being so painted or covered as to have a low visibility which blends into the usually dark interior of the casing which thus becomes invisible from the front thereof, leaving the opening appearing as a barred one which appearance is produced by said front edges of the blades.

These objects of the invention, as well as the many advantages thereof, will more fully appear as I proceed with my specification.

In the drawing:

Fig. 1 is a view in front elevation of a deflector arrangement embodying the preferred form of my invention.

Fig. 2 is a horizontal detail sectional view through the same on an enlarged scale as taken on the line 2-2 of Fig. 1.

Fig. 3 is a vertical detail sectional view through the same as taken on the line 33 of Fig. 1.

Fig. 4 is a transverse sectional view through one of the deflector blades and illustrates diagrammatically the arrangement of the different contrasting surfaces thereof of high and low visibility.

Referring now in detail to that embodiment of the invention illustrated in the accompanying drawings, 1. indicates as a whole the casing of the deflector usually positioned in av building wall 2 and 3 indicate the louvers or blades associated with said casing. The casing comprises upright parallel side walls 4 aand horizontal top and bottom walls 55 respectively which define a rectangular frame open at its front and rear. This frame is set in a corresponding- 1y shaped opening 6 in a building wall and to the front thereof is fixed associated facing enhancing members 7 of suitable ornamentation. This facing provides the front part for the casing as a whole and engages that surface of the wall about said opening 6 to conceal the same. The rear end of the easing frame is connected in any suitable manner with a duct 8 leading from a suitable blower or exhaust apparatus. Quarter rounds 9 or other mouldings are fixed. to the rear ends of said casing and cover and en gage the rear surface of the wall 3 about the opening 6. The interior surface of the easing frame as well as like surface of the duct 8 are painted a nonlight-reflecting color such as black which renders them low in visibility when viewed from the front of the casing.

In the casing thus described, the blades 3 ai'e'arranged in laterally spaced relation and parallel with the side walls thereof. Each blade is preferably made of wood to reduce resonance and vibration and is of a suitable thickness and width. The opposite sides 33 of the blade are painted dead black and the front edge 8" which is semi-circular is painted a contrasting color of high visibility as indicated diagrammatically in Fig. 4. If desired said front or go may be longitudinally fluted but this is not absolutely necessary.

On each end of the blade is secured a metallic shoe 10 secured thereto by screws as best shown in F 3. The front or too end of this shoe which is made semi-circular to it the front edge of the blade, has a pin 11 arranged coaxially with said edge and this pin seats in a recess in the front marginal portions of the top and bottom members 55 of the casing frame to provide a pivotal axis for said blade. The rear or heel end of said shoe projects beyond the rear edge of the blade and carries a thumb screw 12 WhlCh be manlpulated to lock the blade in the desired angular position as best shown in Fig. 2, the shoe and screws also being painted hlae'k to lower their visibility. By means of this shoe construction .the blades may be arranged to deflect or direct the air passing from the duct through the casing, to the desired part of the room to be ventilated.

hen such a deflector casing is in the Wall :of' a theater or the like nothing is visible of the same, except the facing plates and the. front edges of the blades, no, matter from Whatangle the casing as a Whole is viewed orwhat angle the blades happen to be Thus theca'sin-g appears as if havinv a plurality of narrow, vertically arranged bars, Which in its simplicity harmonizes ;any Wall decoration. Thus the deflector easing which has heretofore been an eyesore .is not only rendered more etilcient in operation so star as the desired allglliitl'lby of the blades are concerned but s also more considered by Way of illustration only so that I do not wish to be limited thereto ex.- cept as may be pointed out in the appended clann.

I claim as my invention:

A deflector of the kind described embodylng therein a casing open at 1ts front and r v .'1'- r I I 1611i plu anty Oi deflector .Olaues, a shoe on each end of the deflector blade and having a pin positioned near the front edge of the blade and engaging a part ofthe casing at the front edge thereof to form the pivotal axis of said blade and means on the other end of the shoe adapted to be engaged with a fixed part of the casing to lock the blade in the desired angular position therein.

In testimony whereof, I have hereunto set my hand this 21 day of May, 1927.

IRVING C. STERNBERG.
