UNITE STATES PATENT OFFICE EVERETT S. BUCK AND LEE 1B. METTDLER, OF LOS AN GELES, CALIFORNIA VENTILATING SYSTEM 1 Application filed May 10, 1926. Serial no. 108,004.

This invention relates to improvements in ventilating apparatus and more particularly to apparatus for installation and use in places for public gatherings, such as theaters, school 5 rooms, churches and passenger coaches.

Efforts to secure comfort in crowded theaters, school rooms, churches and other places for public gatherings have led to finally accepted practice of supplying a vast volume of air which is commonly washed and either cooled or warmed anddelivering it at scattered points throughout a room or space and then exhausting it to waste. The air quantities thus handled range from thirty (30) to fifty (50) cubic feet per person per minute, although less than a cubic foot per person per minute, is actually breathed, the remainder being necessary for dilution and air movement, but, because it becomes contaminated and unfitted for breathing purposes this "air is exhausted, as waste, carrying with it the positive or negative heat with which it was tempered. This practice and only by the closest temperature andhumidity regulation,

affords, at best, only average comfort conditions.

provision of means whereby each individual person, as seated in a place for public gathering, may surround himself inan atmosphere conditioned and controlled to meet his personal needs and desires.

Our improvements consist in the novel construction, arrangement and combination of parts as hereinafter fully, clearly and concisely described, definitely pointed out in our claims and illustrated by the accompanying drawing (1 sheet) in which:

Fig. 1 is a diagrammatical floor plan of a place for public gathering and shows an apparatus for conditioning and delivering air in accordance with our invention;

Fig. 2 shows in rear elevation a group of seats equipped with controllable discharge outlets for air;

Fig. 3 shows in side elevation the group of seats as shown in Fig. 2;

Fig. 4 is an enlarged sectional detail of the discharge nozzle;

Among the objects of our invention is the Figs. 5 and 6 illustrate a' modified formlof a controllable outlet. 1

Referring more specifically to the drawing, 10 designates a room or chamber, whichis temperature-controlled, as by any approved heating or cooling system, not shown.

For the supply of breathing air to the room,

1 we provide an air conditioner 11, Which may be of any approved type and construction, such as a washer with air tempering means. From this conditioner 'we provide main ducts 12 having branches'13, which latter lead to the vicinities of fixed'seats, such as the rows of seats 14, shown diagrammatically in F ig; 1. At the discharge end of each branchduct we provide a nozzle 15, as best shown in 4, adapted to control both the flow and di-v rection of the breathing air from the conditioner, to the end that the occupant of the seat may provide himself withthe breathing and comfort condition of his individual need and desire. I

As a means of mounting the nozzle 15, we

. utilize the seat supporting standard 16, which bearing 18 within the nozzleand mount therein a manually rotatable barrel 19, having substantially diametrically opposed intake and outlet ports 20 and 21, respectively, and a projecting manipulating handle wheel 22.

To control the volumeof discharging air, we provide a damper such as 23, for closing or grading the opening of the intake port 20.

e contemplate the provision of a nozzle, as recited, for each occupant of each seat, to

r the end that breathing air may be supplied to each individual member of an audience, according to his needs and desires and this all independent of the general air tempering of the audience chamber. V

In the form shown in Figs. 5 and 6, we show a discharge outlet in .theform of a register carried at the back of a theaterseat and connected with an air condition apparatus in substantially the same manner shown in the preferred'form and which connection in cludes a normally closed valve 30 comprising 7 apedal31 andaspring32. q f In this form the operatorwvhile. seated the vicinity of the register holds thevalve open when he desires the benefit of breathing room.
