VENTILATING SYSTEM.

Application filed November 3, 1922. Serial No. 598,834.

To all whom it may concern:

Be it known that I, ERNST GLANTZBERG, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Ventilating System, of which the following is a full, clear, and exact description.

y invention relates to a ventilating system and aims to provide new and useful improvements in connection with a structure of this nature and is more particularly adapted for use in connection with large hotels, schools, etc.

It is well appreciated that a great amount of difficulty has been experienced in the ventilation of large buildings of the type specified in the preceding paragraph. This difii culty is to be predicated by the fact that it has been heretofore considered necessary to provide either ventilating ducts communieating with each room and hall to be aired, or to utilize fans in each room and hall which would force the air to circulate therethrough.

These expedients, to say the least, have been unsatisfactor the first involving a great amount of expense incident to the installation of the ducts, etc., as well as presenting in many instances an unsightly appearance at the outlet or intake ends of these ducts. The provision of a number of fans for ventilating purposes is also open to objections in that the noise of these fans has been annoying aside from the fact that the installation in this instance also has been expensive, it being noted that the maintenance or a series of separate ventilating units has run into a prohibitive figure.

Thus my present invention aims to provide a ventilating system by means of which an entire floor or a number of the same may be ventilated, it being also noted that the occupants of the floor may optionally cause a cessation of air flow in any one of the rooms thereof, if this is desired.

A further object of my invention is the provision of a system of the character specified, which will eliminate the necessity of a number of separate installations or a series of ducts, thus avoiding expense incident to this type of system.

Further objects of the invention will appear in the annexed specification, taken in connection with the drawings, which latter eration, the single present one practical embodiment of the same, and in which,

Figure 1 is a sectional plan view of the floor of a building equipped according to my improved system, this view being taken substantially on line 1-1 of Fig. 2;

Fig. 2 is a vertical section through the building.

It will be seen that in the embodiment illustrated I have shown my invention as applied to a building which is U-shaped in cross section. In other words, the building includes a pair of wings 5 and 6 and a main connecting portion 7, each floor being provided with a main and branch corridors 9 and 10, respectively, the latter communicating with a series of compartments or rooms 11 each being provided with windows 12 and transoms 13, preferably above the doors 14, which latter communicate with the corridors 10.

This is obviously merely one type of building to which my improved system is applicable, it being noted that I have described the conventional arrangement of so corridors and rooms in a building of this type, although obviously any other arrangement of the partitions of the building might be resorted to without in the least affecting the operation of the system.

Attention is invited to Figure 2, from which it will be seen that I have provided a battery of fans 15 of any desired type, one of which is provided in this form for each two floors. Each such fan or blower is shown conventionally as driven by electric motor 17 Conduit 18 is utilized to enclose the fan. Such conduit has its upper portion connected to an opening 16 at the inner end of the main corridor 9 of an upper floor and has its lower portion connected to an inner end of a similar opening 16 for a lowerfloor.

In normal operation, assuming that the doors 14 are closed and the transoms 13 opened and that one of the fans 15 is in opfan servin to ventilate a plurality of floors in that the air will be drawn in through windows 12 and transoms 13 of each room 11, halls 10 and main corridor 9 and opening 16 of one floor, and expelled in a reverse direction through the similar elements of the other floor; it being also noted in this connection (reference being had to Figure 1) that even the outer- Je i;

most ends of the halls 10 will have a certain amount of air flowing through them. the occupant of any room desires to control the amount of air passing through the same this may readily be accomplished by closing the transom 18 associated with this room, in which instance the air will be incapable of passing into the room.

Thus my invention is adaptable to old buildings as well as to new ones, and an architect, in connection with the latter type of buildings, is enabled to provide an excessive Ventilation with a relatively small fan or blower by simply enlarging the transon'is 13 to a size insuring this being accomplished although it will be seen in many instances that the occupant of a room. may obtain an excess of ventilation by opening the door 14 of the chamber thus presenting an unobstructed passage for the flow or" air.

From the foregoing it will also be appreciated that l have provided a ventilating system in which the necessity of a number of separate units for ventilation of separate chambers or rooms is avoided, it being also seen that the necessity of a large installation is eliminated, thus reducing the cost to a minimum.

Furthermore, each of the rooms and halls will be eliiciently ventilated at a minimum of expense, and thus all the objects set forth in the preamble of this specification will have been accomplished.

Obviously numerous modifications of structure and adaptations of the system may readily be resorted to without in the least departing from the scope of my claims, in which:

1. A ventilating system including in combination with a building having adjacent floors presenting corridors, chambers communicating with said corridors and windows in the outer walls of said rooms, of a fan, and means for connecting said fan to dififerent floors whereby to cause ai to be sucked through said windows, rooms and corridors out one floor and to be expelled into the corridors, rooms and through the windows of the second floor with which said tan is connected.

2. A ventilating system including in combination with a house having similar floors each presenting corridors, chambers in communication with said corridors and windows in the outer walls of said chambers, of a fan and a conduit within which said fan is positioned, said conduit having its ends connected to different floors whereby upon said fan being operated air will be sucked through the windows, chambers and corridors of one floor, through the conduit, and be expelled through the corridors, chambers and out the windows of the other floor with which the opposite end of said conduit is connected.
