VENTILATING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 699,352, dated May 6, 1902.
Application filed August 17, 1901. Serial No. 72,436. (No model.)
To all whom zit may concern.-
Be it known that we, JOHN TITUS, a resident of Oyster Bay, and WILLIAM TITUS, a resident of Old Westbury, in the town of North Hempstead, in the county of Nassau and State of New York, citizens of the United States, have invented certain new and useful Improvements in Ventilating Apparatus; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a partial vertical sectional view of a ventilating apparatus made according to our invention. Fig. 2 is a horizontal sectional view thereof, taken in the line mm of Fig. 1. Figs. 3 and 4 are detail views of devices included in the apparatus.
This invention relates to that class of ventilating apparatuses in which two volumes or streams of air of different temperatures are mingled prior to their access to the room or place to be ventilated.
The object of said invention is to provide simple and effective means for automatically regulating and controlling the temperature, volume, and pressure of the commingled air as the same is supplied to said room or place.
To this end theinvention comprises certain new and useful combinations of parts hereinafter fully described and specified in the claims appended hereto.
A is a cooling-chamber or cooler, which may be of any suitable construction-as, for example, and as shown on the drawings, an iceboX with a horizontal diaphragm a, by means of which a circuitous passage is given to the air as it passes through to more thoroughly refrigerate the same. From the cooling-chamber extends upward a vertical cold-air shaft 15, and placed in suitable relation with the cooling-chamber is an air-forcing apparatus, preferably, and as shown in the drawings, a rotary fan-blower O, which may be driven by a pulley b, and whereof the inlet from the atmosphere or from any desired source of airsupply is shown at c in Fig. 1. This air-forcing apparatus or blower C has two outlets e and d, which extend from the throat of the blower, as shown in Fig. 1. Of these outlets d communicates with the cooler A, while 6 communicates with a secondary vertical air shaft or pipe D, which is parallel with the cold-air shaft B, so that in the operation of the blower (J air is simultaneously forced into the secondary air-shaft D direct from the blower and into the cooler A and thence into the cold-air shaft B. In the throat e of the blower is provided a swinging valve E, which acts in conjunction with vents a b at oppo site sides of said throat, as shown in Fig. 1. This valve is so arranged that by adjusting it in one direction or the other the supply of air to the one shaft or the other may be increased or diminished at will, the air-supply to the one shaft being diminished as that of the other is increased, and conversely, while by bringing the valve against one or the other of its vents the supply of air to one or the other, as the case may be, of saids shafts may be entirely out off. The required adjustment may be given to this valve by means of an arm a attached to an outer end of its pivot b and held by a pin 0 which passes through a hole in the arm into any one of several,
corresponding holes in a fixed section d, as shown.
Located between the two air-shafts B and D is a mixing-chamber E, which at one end communicates with the coldair shaft B and at the other with the air-shaft D. The'end of this mixing-chamber which communicates with the shaft B has a register f, preferably of the semirotative kind, for controlling the inflow of air from said shaft to said chamber. In like manner and for like purpose that end of the chamber which communicates with the secondary shaft D is provided with a register g. Each of these registers has a radial arm h, and these arms of the two registers are connected by a rod 1', so that an impulse or movement given to the one register will be transmitted to the other. The registers are so provided that when one of them opens 5 or enlarges its passages to increase the volsuitable way-as, for example, by a linkjwith the movable part of a suitable thermostat F, so that changes of temperature acting upon the registers f and g the relative volumes of air passed into the mixing-chamber from the two air-shafts are automatically controlled. The mixing-chamber has an outlet into the room or place to be ventilated. This outlet is shown at k and is provided with a register m, by which the outflow of air therefrom may be controlled. The thermostat just hereinbefore mentioned should of course be suitably placed in the room or place to be ventilated. To the registermof the outlet is of the air-mixing chamber E is provided a projecting tube or nozzle 'n, to which in any suitable manner is attached a flexible tube'GJ The free end of this flexible tube being open, air may be conducted at will to any part of the room or place to be ventilated-as, for example, into any desired relation with a couch, bed, chair, or the like, as may be desired.
Upon the chamber E and with its lower end communicating with said chamber is a cylinder H, in which is a longitudinally-movable plunger I, the upper projecting end of which bears against the under side of a loaded lever J. This lever is connected by a link 0" with a crank-arm s on the register m of the outlet k of the chamber. When the pressure within the chamber exceeds a desired or foredetermined limit,the plunger I is lifted,thereby actuating the lever J to operate said registerto more or less close the same, thereby regulating the volume of the mixed air from the chamber to the room or place to be ventilated and controlling the pressure under which it is so admitted to an extent proportioned to the degree to which the air is throttled in its passage through said register. Any desired number of mixing-chambers and their herein-described adjuncts may be employed in connection with the two air-shafts, according to the number of stories of the structure to be ventilated. The two volumes of air, that from the air-shaftD being of the higher temperatureas, for example, the normal temperature for the time being of the outer atmosphere-=while that from the cold air shaft is refrigerated or of lower temperature, meet and commingle in the mixing-chamber, and thus reach a temperature common to both before issuing from said chamber to the room or place to be ventilated.
