WINDOW-SCREEN.

vTo all whom 'it matfconcern:

Be it known that I, LOWELL C. BAssroRD, a citizen of the United States, residing at 'La Grange, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

The screen of the present invention is more especially designed to be used -in co-nnection with car windows', although obviously it could be utilized in other places departing from the spirit o'f the invention. 1

One object of the present iiivention is to employ a surface of porous absorbent material, which will serve as a screening surface, and to provide means for keeping said surface in a continual moist condition.

A further object `of the invention is to construct the frame work of t-he screen yso that it may be disassembled and to position reservoirs for containing the liquid within said frames in sucha manner that when the frame work is separated the reservoirs .can beeasily removed for the purpose of renewing the supply of liquid therein.

A further object of the invention is to embody a surface of metallic mesh substance which will overlie the surface of absorbent substance and save this latter surface from the wear and tear incident to the use of -the screen.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a front elevationof one of the screens of thepresent invention; Fig. 2 an enlarged elevation showing the front portion of the frame removed;l Fig. 3 an enlarged sectional detail showing one of the reservoirs in elevation; Fig. 4 an enlarged sectional detail showing one of the reservoirs and the manner of securing the absorbent porous substance to said reservoir.A f

It is desirable under certain conditions to cause the air which enters through the screen to pass through a moistened surface so that the air willbecome cooled during such entrance and enter into the room in a cooled and moistened condition, and it is the object of the present invention to produce this result in a simple and efficient manner and by the'use of a device which` is simple in op Specification of Letters Patent.

erationand will not require any change in the outward appearance or in the method of use of the screens nowemployed.

The screen when used in conjunction with car windows comprises companion sections .5 which are hinged together. -This construction is, however, old and well known in screens, especially adapted for use. on cars, andthe present invention is only shown as applied to `this particular form of screens for -the purpose of illustration. Each of the Isections 5 are exactly alike in construction and principle of operation and a detailed' description of either one of these sections of the sections 5 will be dealtwith.

The screen comprises what may be termed an outer frame Work 6 and an inner frame work 7 these two frame works being secured together through the medium of thumb screws 8 or other suitable fastening devices. Each of the frames have extending longitudinally thereof along their upper and lower rails a groove 9, the two grooves cooperating to provide-a recess adapted to receive elongated tubes 10. yEach of the tubes is closed at one end by a fixed Cap 11 and at its opposite end by a removable .Cap 12 and each of the tubes has-enteredy thereinto the longitudinal ends 13 of a section'of absorbent porous material 14, said ends being sewill be sulicient for present purposes;

cured to the tubes by. clenching them between the free ends of the metal comprising the tube, as shown more clearly in Fig. 4 or any other well knownand applicable manner of securance may be employed.

As shown in Fig. 4, the ends of the ma-v rial. There will, of course, bea movement of the liquid from the tube into the material in both directions. :That is to say, the liquid will run on to the material from the upper of the tubes 10 and from the lower .of the tubes 10, although the movement of the lowertube will be veryslight .in comparison 'with the movement out from the upper tube since the movement from this latter tube will be assistedv by the action of gravity. It is therefore not the intention to insure a more complete moistening of the material by employing two tubes but rather to provlde an arrangement so that when the vscreen is reversed a tube containing liquid will be in position to moisten the surface of the material, thus enabling the screen to be used twice as long without removal for the purpose of replenishing the supply of liquid. If it were not for this point of advantage, the device might be equally operative with only one of these tubes which would then be located preferably upon the upper end of the frame.

The lower frame work 9 has fixedly secured thereto a surface 15 which is of the ordinary mesh wire used in screening. This surface is presented to the outside and receives all of the cinders and other matter which may be projected against the surface of the screen during usage, thus saving more or less the porous absorbent surface from the wear incident to the usage of the screen, since this porous surface is at all times turned to the inside. It is understood that this wire mesh surface is simply a protector for the surface of absorbent material and that it does not enter in any way into the inoistening of the air. If the conditions are such that a guard is not necessary for the porous substances, the wire mesh may be dispensed with.

The air after passing through the metallic surface 15 will pass through the porous surface 14 and since this remains in a constant moist condition, the air will be cooled during such passage, and will enter into the interior of the room in a cooled and moist Y condition, thus materially improving the ventilation inthe interior of the room by eliminating the heated air which is ordinarily conducted thereinto. The porous sur-` face further serves as a substantial and eiicient filter for preventing all dust and other fine particles which might otherwise enter the room throughSthe metallic screening from passing thereinto.

Since the frames are of a nature to be easily separated, the two sections VV.of material, namely, the section 14 and the section 15, can bel readily and quickly cleaned, the tubes 10 and the material 14 being very easily removed from (the body of the frame of the screen for the purpose of washing, or otherwise cleansing this material.

The absorbent porous material 14 referred to heretofore, I prefer to be of some materialprovided with a nappy surface, such for instance, as burlap, or some kind of linenwhichvis made with a nappy surface.

I claim:

1. A window screen, comprising a framework lformed of two registering sections, adapted to rest against the sides of the window casing, means for holding said sections in close engagement .with one another, a metallic mesh surface fixedly secured to one of said sections, and a fiber mesh surface superimposed over the metallic mesh surface and held in position by the locking engagement of the two sections, and means for maintaining the fiber mesh surface in moist condition, substantially as described.

2. A window screen, comprising a surface of absorbent porous material, a reservoir -for liquid provided with an elongated slit, the material being entered into said slit and clenched between the edges of the metal along said slit, and a framework in which said reservoir is mounted, substantially as described.

3. A window screen, comprising a framework formed of two registerin sections, adapted to yrest-against the si es of the window casing, means for holding said sections in locking engagement with one another, a metallic mesh surface ixedly secured to one of said sections, the' engaging surfaces of the upperfand lower rails of said framework being grooved, a tube for containing liquid seated in each of said grooved surfaces, and a section of absorbent porous material secured to said tubes' and maintained in moist condition by the liquid,-

within said tubes, substantially as described.

4. A window screen, comprising a framework formed of two registering sections, adapted to rest against the sides of the window casing, means for holding said sections in locking engagement with one another, a metallic mesh surface ixedly secured to one of said sections, the engaging surfaces of the kupper and lower rails of said framework being grooved, a tube for containing liquid seated within said grooves, said tube having an elongated slit, a section of absorbent porous material entered into said slit and clenched between the edges of` the metal along said slit,V substantially as described.
