BODY CONDITIONING APPARATUS SUI'I' Filed Deo. 1e, 41959 INVENTOR Pau&.Banl
Hfs ATTORNEY Patented i Sept. 16, 1941 l* UNITED STATES PATENT OFFICEl BODY CONDITIONING APPARATUS SUIT Paul A. Bancel, Upper Montclair, N. J., assignor to Ingersoll-Rand Company, New York, N. Y., a corporation of New Jersey Application December 16, 1939, Serial No. 309,636
(Cl. 12s-144) 6 Claims.
This invention relates to air ventilating apparatus and, more particularly, itrelates to a suit continually supplied to the space in order to ventilata it.
A further object is to provide a suit having a ventilated space about the wearers body in which air is introduced in such a manner that it travels over the entire body of the wearer before escap.
ing from the suit.
These and other objects will be apparent from 'the following disclosure of which the drawing bient temperature may be in the neighborhood of y 100 F. and consequently, such a person is also at such a temperature. Furthermore, the humidity is so high that a person can get no relief by the evaporation of body moisture or perspiration with the result that he suilfers considerably. If the metabolic heat couldbe absorbed or removed from such a person, he would be cooled and enabled to work although the ambient temperature was high.
In orderl to remove the metabolic heat, I propose subjecting the persons body to an atmosphere of air at ambient or body temperature which is dry enough to absorb the metabolic heat solely by evaporation of moisture from the wearers body. Dry air, or air of low relative humidity for such a purpose, may be produced conveniently in some localities by expanding vcompressed air which has been cooled to ambient temperature -and dried at about 100 pounds gage pressure to substantially atmospheric pressure.
Accordingly, it is an object ofthe present invention to provide a method and means to cool and ventilate a persons body.
It is an object of the present invention to provide means whereby the metabolic heat of a per-7 son may be removed by use of air of low relative humidity.
Another object is to provide means whereby a person may be cooled by the evaporation of body moisture into a medium of low relative humidity.
Still another object is to provide means whereby compressed air may be expanded and employed tocool and ventilato a persons body.
It is an additional object of this invention to provide a suit or garment wherein a ventilated space is provided around the wearers body.
It is also an object to provide a suit having a ventilated space about the wearers body which permits freedom of movement by the wearer.
Yet another object is to provide a suit having a space about the .wearers body wherein air is forms a part and in which c Figure 1 shows a sectional view of the present invention, Figure 2 is a view partly in elevation and partly in section of the present invention,
. With reference to the drawing, it will be seen that the body is covered by a close tting absorbent inner garment, such as a woolen garment, in order to absorb any moisture or perspiration and to provide a uniform dispersion of such mois-Q ture into the surrounding air. With such a garment, the cooling eifect is uniformly spread over the wearers skin, and, at the same time, the garment acts as a "buffer" in that it prevents direct contact-between the wearer and the warm inner surface of the suit 2 which completely envelopes the wearers body except for the head, hands and feet. The suit 2 is made of some material which is impervious tov air and' appropriate seals 3 are providedat the wearers ankles to prevent any leakage between the suit andthe ankles. Similar seals 5 are placed at the 'wearers kwrists and,
for the same purpose, a seal 'I surrounds the l wearers neck.
The suit may be donned by opening the "zipper 8 at the front of the suit and the belt Il which viously, the air supplied directly by the compressor is at a high pressure.u By expanding this air in the manner explained hereinafter the pressure is reduced to a pressure slightly greater than atmospheric pressure. The conduit I3 is Y u ankles.
supported at the wearers backon a hook I clamped to the belt II and the suit 2 by rivet I1.
From the back of the s uit the conduit I3 extends to the front of the suit where it is coupled by means of coupling ||3 to another conduit 2|.
As shown in Fig. 4, the end of conduit I3 is provided with a bushing 23 having a central 1 channel 25 and provided with threads 21. The
bushing. 23 is designed to cooperate with the -member 23. The conduit 2| is supplied at the open end thereof with the nipple 3| having bayonet points 33 adapted to be inserted through the slots 35 in the rear wall 31 of the member I3. Adjacent the open end of the nippleA 3| a partition wall33 extends acrossthe bore 4I of the nipple and has an oriiice 43 centrally located therein'. When the air supplied by the compres'- sor at a high pressure passes through the orilnce, it expands substantially by the irreversible adiabatic process with the result that, as theA pressure decreases and the volume increasesthe relative humidity of the air is greatly lowered, while the temperature is substantially unchanged. Within the member I3 is placed a guide wall 45 on which the nipple 3| rests when it is iny serted in the member. The nipple is held within the member`l3 by the co-action of the bayonet points 33 and the rear wall 31.
Between the bushing 23 and the guide wall 45 a rubber washer 41 is placed which surrounds the en d of the nipple 3| This washer acts as the bushing 23 and the nipple 3|.
The check valve is provided with holes 5| of suflicient diameter so that they will not be entirely covered by the end oi' the nipple 3| when that nipple pushes the check valve away froml the seat or washer 41. Since the member 23 is connected tothe bushing 23 by threads 21, the member 29 will be continually secured to the conduit I3. Ii the nipple 3| is not held in the member I3, the air pressure supplied through conduit I3 will hold vthe check valve 43 on the seat provided by 'washer 41 and thus prevent escape of air from the conduit I3. However,-
when the nipple 3| is inserted into the member I3, it will remove the valve 43 from its seat,
' permitting the passage of airaround the valve v The fitting 53 is provided with appropriatepas- -a cushion for the check valve 43, lying'between v Beil, located adjacent the wearers-wrists, must be provided in order that 'there will be a circubelt shall not prevent the passage of air by the i wearers waist, corrugations 63, .10, 1| and 13, formed of the same material as the suit, are provided within the suit. It will thus be seen that a Ventilating suit has been provided which enables dehumidied air totravel freely over the wearers body in order that the wearer may be cooled.
