CHAIR-SEAT.

Specification of Letters Patent.

' Patented-July e, 1907.

To all whom it may concern:

Be it known 'that I, SMITH N. MoCLoUD, a citizen of the United States, residing at ,Marysville in the county of Union and State of Ohio, have invented a new and useful Chair-Seat, of which the following is a specification. v

The object of the present invention is to provide a novel form of hygienic chair seat having means that will permit the circulation of air therethroughso as to maintain the seat in comparatively cool and more healthful condition than the ordinary solid seat.

Two embodiments of the invention are disclosed in the accompanying drawings and described in the following specification, but it will be noted that the invention is not limited by the appended claims to the exact structures disclosed.

In the drawingsz--Figure 1 is a perspective view of one embodiment of the invention. Fig. 2 isl a cross sectional view therethrough. Fig. 3 is a sectional view on the line 3-3 of Fig. 2. Fig. 4 is a plan view of the central portion of the casing, illustrating the central opening therethrough. Fig. 5 is a bottom plan view of a modified form of structure. Fig. 6 is a cross sectional view therethrough. Fig. 7 is a sectional viewon the line 7-7 of Fig. 6.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

Referring first to the structure disclosed in Figs.` 1 to 4 inclusive, it will be observed that a support 8 is ernployed in the form of a fiat base-board having one or more openings 9 through its central portion. Mounted on this base or support is a casing comprising a top wall 10, and a bottom Wall 11i, These Walls have central elongated openings 12 therethrough. The margins of the top and bottom walls around the openings are connected by an inner wall 13. As a result, it will be noted that the casing is provided with a central elongated opening 14, located over and alined with the openings 9 in the base. The casing is filled with suitable cushioning material 15 that surrounds the central opening, said material being held against movement in the ordinary manner by ties 16 connecting the top and bottom walls. `Cushioning material 17 is kalso located upon the top wall 10 of the cushion or casing, and covering this material and the casing is a facing sheet 18, which facing sheet extends directly across the central opening 14, and extends down-- wardly into the same. A backing sheet 19 is secured to theunder side of the casing, and also extends across i the central opening 14, being curved upwardly into the same, so that the portions of said backing sheet and facing sheet that extend across the opening are abutted, being fastened by lines of stitching 20, or by any other suitable means. As a result of this structure, it will connected by alined openings 23 extending through the sheets. The seat is held in'. position on the base` by any suitable means, as for instance, tacks or fasteners 24 extending through a binding strip 25 located over the margins of the facing sheet, said fasteners passing through the outer margins of the facing sheet of the top and bottom walls 10'and i'l ofthe casing into the base. By this arrangement, it will be-observed that air can circulate freely through the ccntral portion of the seat, maintaining the saine in cool and healthful condition. At the same time, the structure of said seat is simple, and adds but little to the cost of manufacture.

A slightly modified form of the invention is illustrated in Figs. 5, 6 and 7. In this structure, the base or support comprises an open frame 26 bridged by a ,pair of ribs 27 or other supports, which may bc of any suitable structure. These ribs constitute supports for springs 28.` In other respects, the structure is substantially the same as that already described. A cushion is employed comprising top and bottom walls 29 and 30, having central openings, the margins around the openings being connected by an inner wall 31. Thus the casing has a central .elongated opening. Cushioning material 32 is locatedvin the casing, and

other cushioning material 33 is arranged upon the same. Over the latter is placed a facing sheet 34 that extends across the central opening, and a backing sheet 35, secured to the under side of the cushion, also extends across the opening. These two sheets extend into said opening towards each other, and have the portions located therein secured together, as shownat 36. As a result, an upper channel 37 is formed in the seat, and this channel has communication with the under side of said seat through openings 38, formed through the abutted portions of the facing and backing sheets. It will be apparent that this formof construction has exactly the same advantages as those already described, and it will also be evident that the cushions can be manufactured and sold separately from the base or support, so that they may b applied to any suitable chair.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape,

y, proportion, and minor details of construction, may be i resorted to without departing from the spirit or sacri- .cing any of the advantages of the invention.
