` Sept 16, 1952 E. A. KosToPouLos VENTILATING AND INSLATING UNDERSHIRT Filed Dec. 27, 1949 I INVENTOR: l fmanue/jro//oa/of V ATTORNEY Patented Sept. 16, 17952 .VENTILATING 'AND'I'NSULA'rrNG ,Y jUNDERsi-:mrrY z .Emanuel Kostopoulos,'l)rexelHill, Pa. Application December 2,7,v 149119, Serial'NoL The invention* describe may be' manufactured and used by or for the Gov- "ernment .for governmental purposes without the payment to me of vany royalty thereon.

This invention relates to an undergarment to be worn under very heavy clothing in extremely cold climates for the purpose of spacing the clothingfrom` the body to provide a quiet or dead air space between the clothing and the skin, which will serve as a heat insulating layer, and which y will also minimize the absorption of perspiration by the clothing. K.

It is an object of the invention to provide such an undergarment in the form of a vest, which is formed of a material which doesnot readily absorb moisture, which will not unduly irritate the skin, and which is so constructed as to lend itself to rapid production on conventional knittingV machines.

A further object of the invention resides in d herein, if patented,

@roxanne (c1. ca -176) n 'i'.(Granted under-the act of March il, F1883, as 'amendedAprlBm 1928; 370 O. G.

large diameter or thickness to adequately space the clothing from the skin of the wearer.y

These vertically extending cords are horlthe provision of an undershirt adapted to be disposed between heavy clothing and the skin of the wearer, which is constructed of relatively thick cords or chains horizontally spaced to provide a plurality of vertically-extending dead air spaces extending to the neck of the garment and across the shoulder portions thereof.

Another` object of the invention consists in the provision of such a garment in which the vertically-extending cords or chains are united by non-elastic inlay or filler threads and elastic threads, whereby freedom of bodily movement is permitted without permanent distortion of the' garment.

Other objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawings, in which:

Figure 1 is a front elevation view of the ventilating undershirt or vest;

Figure 2 is an enlarged fragmentary Vdetail view showing the manner of incorporating inlay or filler threads and the elastic threads; and

Figure 3 is an enlarged detail view showing in a general way the construction of the cords and threads, part of the cord being broken away to more clearly show the knit construction.

' Referring to the drawings more specifically,

the numeral l indicates the undershirt or vest zontally spaced to provide a series of quiet or dead air spaces 6 therebetween and may be maintained in their proper relationship by inlay or filler threads 'l which may be vertically spaced as clearly indicated in the drawings. The vertically aligned spaces 6 also provide longitudinallyextending channels which direct perspiration vapors, etc., toward the neck and shoulders where it may more readily escape, particularly when the throat portions of the outer garments are loosened.

Both the cords 5 and the ller threads 1 are preferably formed of nylon or other material having low moisture absorbing qualities and the filler threads 'l are formed in a zig-zag path to connect adjacent cords 5. This construction is shown morev clearly in Figure 2 in which the verticalv portions of the threads which are inlaid in the cords are indicated by the numeral 8 as shown in dotted lines in that gure.

In order to further maintain the cords or chains in their relationship and to provide a snug iit of the garment about the body of the wearer, elastic threads 9 of rubber covered by plaiting l0 of nylon thread are provided. These elastic threads 9-I0 are incorporated in the body of the garment in zig-zag formation and substantially parallel in juxtaposition to the filler threads 1 which also connect the cords 5. As indicated above, this Ventilating undershirt or vest lis intended to be worn in extremely cold climates vand is placed next to the skin of the wearer so as to space the heavy garments usually worn in extremely cold climates, from the wearers body. Consequently, when this undershirt is worn, a plurality of vertically extending dead air spaces 6 are provided which serve to insulate the body and also prevent the outer garments from absorbing perspiration, etc., from thebody, which would tend to nullify the heat-retaining qualities of the garment. Also this spacing of the outer garments allows any moisture such as perspiration to evaporate more readily and the vapors may pass upwardly through the channels B and escape around the neck of the garment. Moreover, by reason of the fact that the several elements of the shirt are formed of nylon or other material having little or no moisture absorbing qualities, the chilling oi the wearers body by being in contact with wet garments is avoided. n

In accordance with the patent statutes I have rality of horizontally spaced vertical cords ,ofv

relatively large diameter formed of Warpknitted nylon, and vertically spaced filler threads cirela.- tively small diameter connecting said cords.

2. A Ventilating undershirticomprising aplurality of horizontally spaced vertical cords ofl relatively large diameter formed of Warp-knitted nylon, the spacing of said cords being y at leastv as great as the diameter thereof, and vertically spaced ller threads of 'relatively' small diameter connecting adjacent cords. Y

i3. A Ventilating undershirt comprising a -plur'ality .of horizontally spaced verticallyarrang'ed cords` of V relatively large diameter, vertically spaced ller threads of relatively smallrdiametei- 4 connecting said cords, and elastic threads also connecting said cords.

4. A Ventilating undershirt comprising a plurality of horizontally spaced vertically arranged cords of relatively Ylarge diameter, and sets of filler threads and elastic threadsarranged in AZig-Zag V'atterxjlto connect adjacent cords.
