SUIT FOR CIRCULATING CONDITIONED AIR ABOUT A PERSON Filed Aug. 11, 1944 Patented Dec. 31, 1946 SUIT FOR CIRCULATING CONDITIONED AIR ABOUT A PERSON Edward L. Schulz, Syracuse, N. Y., assignor to Carrier Corporation, Syracuse, N. Y., a corporation of Delaware I Application August 11, Midi, Serial No. 549,017
This invention relates to the arts of refrigeration and heating, and more particularly to the air conditioning of the human body while working under high temperature conditions or low temperature conditions.
Operators working in the cabs of overhead cranes, furnace and laundry operators, airplane pilots in jungle operations and laboratory technicians are confronted withhigh temperature ambient conditions which frequently prevents them from working efficiently and sometimes results in complete stoppage of work.
Under some conditions the room in which the operators must work may be air conditioned; however, there are circumstances in which air conditioning of the room or cab or space in which the operator must Work cannot be physically accomplished and there are also circumstances under which'air conditioning of the entire space in which the operator works is uneconomical.
It is an object of the instant invention to provide an air conditioning article of clothing for operators working under extreme temperature conditions.
It is another object of the invention to provide an air cooled jacket for operators working under high temperature conditions.
It is still another object of the instant invention to provide an air cooled combined jacket hood for operators working under high temperature conditions.
Other objects and the nature and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing, wherein:
Fig. 1 is a vertical cross section of a room at a high temperature in which an air cooled operator is working; I
Fig. 2 is a view in elevation of a combined hood and jacket in accordance with the invention;
Fig. 3 is a vertical section taken along line 3-3 of Fig. 2; and
Fig. 4 is a fragmentary detail of the air hose inlet showing its association with a portion of the jacket.
Referring to the drawing the self-contained refrigeration apparatus lo includes compressor, condenser, evaporator, evaporator fan and filters and is so located with respect to the operator II that the cold air circuit which includes passage over the evaporator of the unit I may flow to the operator H through the flexible cold air conduit l2 and may be connected to the jacket l3 at the level of the hip as shown in solid lines or alter-. natively the cold air hose I2 may be draped over 3 Claims. (Cl. 2-2) flexible suspension l4 attached to the ceiling of the room l5 and connected to the jacket l3 at shoulder height. Because of high temperature operating conditions within the room IS, the operator l I is provided with the air cooled jacket l3, so that he may carry out his work eificiently.
While but one operator is shown in the drawing, there may be more than one operator within the room I5 provided with duplicates of jacket 13 and more than one hose l2 may lead from the refrigeration unit ID to the various operators.
While the unit H] has been shown as being located within the room IE it may be located outside of the room l5.
Figures 2 and 3 show a garment having a hood and jacket combination; the helmet portion of the garment may be omitted under certain circumstances and a gathered construction about the neck substituted. Y
As shown in Figures 2 and 3, the garment l3 comprises a body portion l6, sleeves I! provided with adjustable wrist straps l8, a hood 19, a transparent plastic eyeshade 20 having an air outlet 20a associated therewith, a slide fastener closure 2| for the front thereof, built-in support 22 which serves to support the garment in such relation to the shoulders of the wearer that the shoulders of the garment are spaced from the shoulders of the wearer, and a cloth deflector 23 stitched to the interior of the body portion H5 at 23a and 23b, which serves to diffuse the incoming air. The built-in support 22 comprises a pair of generally U-shaped elements stitched to the body portion H5 at 22A and 223. The length of the U-shaped elements of the support 22 are of generally less dimension than the corresponding dimension across the shoulders of the garment front to back so that the U-shaped elements support the shoulders of the garment above and away from the shoulders of the operator. The jacket [3 may be gathered at its bottom as shown at 24'.
The material of the jacket l3 including the Hood l9 may be a closely woven cotton poplin, the weave of which effects a control on the rate of air escaping through the-material. also escape at the plastic eyeshade and in fact the plastic eyeshade may be eliminated under certain circumstances and if desired. Inside the hood, may be provided fasteners 25 for holding a helmet 25 adapted to be worn by the operator, so that when the operator turns his head, vision will not be impaired since the hood and helmet will move substantially as a combined unit, and
The air may aerasac at the neck through the space between thegathered margin at the neck and the neck-or the wearer. As the pressure between the jacket and the body of the wearer is greater than the ambient within the high temperature room, the jacket breathes" in the sense that air passes outwardly through the pores of the cloth.
While the waist of the jacket may fit snugly, it
will at times be desirable to have it lit a little looser especially when the hose connection is near the shoulder blades, so that air will then be able to flow downwardly over the limbs of the wearer.
The hose is generally attached with friction fit to the jacket It so that if the wearer, such as an airplane pilot, has to disengage himself from the hose, he may do so quickly.
The cloth deflector 23 prevents direct impingement of the air leaving the hose on the body of the wearer and, in eilect, it diffuses theair so that one spot onthe body of the wearer is not subjected to forceful and uncomfortable impact.
The support 22 which supports the shoulders of the garmentin spaced relation to the shoulders of the wearer enables circulation over the body in a manner which could not be eflected if the jacket rested upon the shoulders. The construction of the support in cooperation with the garment is such that an area or space 'is formed for circulation about the support and over the shoulders which is highly beneficial in cooling the person.
The escape of air from the jacket l3 takes place through the sleeves, through the cloth itself, at the waist and about the eyeshade when a helmet is used, or between the gathers about the neck when the helmet is omitted.
It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawing and described in the specification but only as indicated in the appended claims.
What is claimed is:
1-. A garment for use by an operator working in a space wherein the ambient is at an abnormal temperature which comprises a jacket, support 46 the operator.
