EDVJ'ARD S. 'GILFILLAN, OF BOISE, IDAHO.
Application filed June 19,
1 0 aZZ to 710m it may concern Be it known that I, EDWARD S. GILFILLAN, a citizen of the United States, residing at Homefield, R. F. D. do. 1, Boise, in the county of Ada and State of Idaho, have invented a certain new and useful Air-Girculation Garment, of which the following is a specification.
The purpose of my invention is to cool the body of the wearer of one of my garments by air currents up or down, in or out, through the garment, caused by the movement of the body of the wearer and effective because of the construction of the garment.
A; further purpose of my invention is to form a garment intended for circulationof air upon a pumping principle and preferably to hold the end of the sleeves and legs of the garment away from the wearer in order to increase the effectiveness of the pumping action.
' A. further purpose of my invention is to support a union garment or separably connected garment intended for air circulation use by suspendermso that the upper part of the garment may not only be relieved of the weight of the lower part thereof, but spaced from the wearer and fitted for air circulaion.
A further purpose of my invention is to hold the front and back of the blouse of an air circulating garment away from the body of the wearer and to lift the garment to give shoulder spacing for circulation.
A further purpose of my invention is to provide air openings at the side of agarment in connection with spacing means for the upper part of the garment to secure circulation. A. further purpose of my'invention is t provide air openings for a garment with means for covering them, both to close them and to improvethe appearance. 7 p
it further purpose of my invention is to provide a suspender-supported union garment with removable closures along the shoulders and outer sides of both arms, as the means of entrance to it.
A further purpose of'my invention is to removably connect theupper part of a union.
garment by means of suspenders, preferably at the front and most desirably using the same suspenders by which the lower part of the garment is supported.
Further purposes of my invention will Specification of Letters Patent.

appear in the specification and particularly? in jhe claims thereof.
l have preferred to illustrate my invention by but one of the various, forms in which it may be advantageously used, selecting therefor a. form which is simple and inex- 1 taken upon a: line corresponding to 3 3 of Fig. 2.
Fig. 4c is a broken side elevation of a garment shown in Fig.'1, with the arm raised.
Fig.5 is a broken elevation of the bottom of one of the legs of'the garment inthe drawings.
Similar numerals of reference indicate like parts.
The principle upon which my invention operates is that the wearer in working, actually pumps air,that is, forces the air up and down around his body, evaporating any perspiration and cooling him by the air itself and by this evaporation.
l have preferred to form my garment as a union garment, recognizing, however, the fact that'the integrality or non-integrality of the upper and lower parts of the garment does not affect the principle of my invention, providing the cooperative structure invented by me be secured. Again, I show the union garment as made up of a blouse (by which term I intend to include all types of cover ing for the upper part of the body without discrimination between shirts, coat-like structures, garments technically known as blouses and the like) and a nether garment of which I prefer the pantaloons,though the bifurcation of the lower part is not essential. in any event, the combined garment is most useful when worn without other body covering.
In the garment I show arms 10 and legs 11 secured to a body 12. I have .formed the parts particularly subjected to greatest wear and strain, including the legs and the.
give weight or body or stiffness enough to these parts so that they will lap with 17 away from the shoulder of the wearer,
may be secured at intervals by the suspender support of the nether part of the garment during the movement of the wearer. The fullness of the back and trout provide for air pumping action front and back, as the wearer leans forward and subsequently raises his body or arms, which action is rendered more eil'ective by stiffening as at 18 and 19 by which the ends of the sle ves and legs are held away from the wearer and open for air passage. The stiffening may provide enough weight to assist in keeping sleeves and logs from undue wrinkling if desired, though for many uses such weight would prove objectionable.
The air pumping action is also assisted by providing for extension of the sides forwardly and rearwardly by openings or slits in the sides of the garment beneath the arms as at 20. These openings may be of any desired form or length. They are most effective when they extend from the under of the arm into the nether garmentsay half way down the upper leg portion of the pant-aloons and are free to flap open and i l at with the movements ot' the wea er to assist in the pumping action. The slits could even be. netted as at 21, though reducing their utility. To more effectively oid exposure of the body through the ings when active work is not being performed, 1 provide flaps, as at 22. which may be butt ned at 23 to cover the openings, but which are shown as buttoned back from the openings, as at 2%.
The g..:ment front is intended to be con structcd of relatively firm material, e. haviug enough body to tend to Fall forward bv its own wei T his because oi the blouse construction and support would give a pumping action in itself, which is increased by the further movement permited by reason of the side slitting. The slitting offers the additional adventu of givi g increasing air inlet with the :LClClltlOllitl torward movement of the front. The relatively firm material of the "front may, of course, be the same material of which the remainder of the garment is constructed.
The garment is provided with removable fastenings from the neck to the lower end course, particularly suitable where the blouse is permanently attached to the nether garment.
v here the nether garment is bifurcated and secured to the blouse fixedly, I prefer to provide it with a seat flap 26, bottoned at 27. The suspenders 15 may be removable to facilitate washing and are shown as fastening at the front at 28. In the rear I prefer to attach them removably to the seat flap, as at 52, in order that greater freedom of movement of the body in the garu'ient may be allowed when the flap is opened.
1 secure additional support for the blouse portion of the garment to lift it free from the shoulders by fastening the garment, preferaoly removably, to the suspenders some sue 1 points as 30, finding that I can lift the garment away from the body and shoulders much better by this means with thinner and lighter material, holding it away a much larger part of the time than by dependence upon the support of the lower portion of the garment alone trom the suspenders.
I prefer to make the points of support in the front rather than at the baclr and at the front only. in order to prevent the garment from clinging too closely to the front oi the wearer, I provide spacers in the form ir-ads upon the under side or": the garment, it placing them near enough to the 3), so that the fastenings shall L pull the garment in toward the wearer ol'iiectionably and shall not interfere with the pumping action which I aim to secure. The character of tastenings at 30 should also be accommodated to this function.
In operation, the bending of the body of the wearer forward and backward, as well as the lowering and lifting of the arms of the wearer cause the spaces at the back and front, respectively, between the blouse and the body of he wearer the one to be reduced and the other increased alternately with coincident rush oi": air from the one space and into the other. Substantially the entire front and back of the garment at the middle swing away from and toward each other, respectively, opening and closing the side rents. A part of the air pumped by the alternate closiu oi? these spaces at the upper back and front passes from the one space about the sides of the wearer and into the other space; and practically all of the air admitted as the wearer leans forward and expelled as he straightens or leans backward, 2'. (2., pumped bythe opening and closing of the middle part of the garment, is driven out of the garment through one or more of the openings at the neck, sleeve ends, open sides and at the bottoms of the legs. The result is a nearly continuous circulation of pumped air between the wearer and the garment, which in practice has been; found to pass up and down the legs as well as in and out the sleeves, evaporating the perspiration and giving a three fold benefit. It avoids the objection of the presence of the perspiration itself, the air cools by its own circulation, and the evaporation of the perspiration causes heat units to be absorbed in the operation.
In my consideration of the slitted sides of the garment, I have regarded these sides as open when the slitting was capable of opening and closing effectively to accommodate the pumping action, even where the space left open by the slit is somewhat covered by netting or other quite porous means of obscuring the view of the body of the wearer.
It will be evident that various parts of my invention are not only separately new but highly advantageous in separate use as well as in combination with other features making up my preferred form shown.
It will be evident tl'iat the support for the parts away from the body, as well as the inlet and outlet air spaces, and the spacing.
from the body, so as to secure spacing and pumping action, may be obtained by other means than have been illustrated by me, without departing from the spirit and scope of my invention and that the detail even of the particular means shown by me may also be greatly varied.
