LIFE-SAVING MATTRESS.

SPECIFICATION forming part of Letters Patent No. 325,227, dated August 25, 1885. Application tiled May 25], i885. (Xo model 'o all whom it may concern.-

Be it known that L ALBERT A. YOUNG, of Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful [mprovementin Mattresses, Uush ions, &c., of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertai ns to make and use the same, reference being had to the accompanying drawings, forming part of this specifica-- tion, in whichl `igure l is an isometrical perspective view in longitudinal section of a mattress embodying my improvement; Fig. 2, a like view in transverse section of a cushion embodyingmy improvement; Fig. 3, a side elevation of one ofthe stays and two of the attaching-loops for the tufting-cord or upholstering-twine, a portion ot' the air sack being shown in section; Fig. 4, a vertical transverse section of the parts shown in Fig. 3; Figs. 5, (i, and 7, perspective views representing modifications ofthe attaching loop or eye for the tuftingcord, and Fig. S an enlarged sectional view.

Like letters ot reference indicate corresponding parts in the different figures ot' the drawings.

My invention relates more especially to that class of mattresses, cushions, Src., which are known to the trade as life-saving, being provided with upholstered air sacks adapted to be inflated; and it consists in a novel construction and arrangement of the parts, as

hereinafter more fully set forth and claimed, the object being to economize in the cost of manufacture by saving in labor and materials, and also to produce more durable, effective, and otherwise desirable articles oi' this char acter than are now in ordinary use.

The rubber sacks heretofore employed in goods of this character have in some instances been provided with a series of short interiorly-disposed rubber tubes, the ends of the tubes being respectively attached to the top and bottom of the sack and opening outwardly through the same, and the tufting cords of upholstering-twine passed through the tubes from top to bottom of the mattress or cushion. The employment of tubes is,

however, objectionable in some respects, but principally because of their cost and the dificulty of attaching them in such a manner as to form perfectly durable and air-tight joints where they open outwardly through the sack. They also operate as fines through which the air passes, and therefore render it disagreeable to sleep on a mattress provided with them, especially in cold weather.

My invention is designed to obviate these objections, and to that end I make use of means which will be readily understood by all conversant with such matters from the following explanation: In the drawings, A represents the body of the sack, which is composed ot' rubber, rubber-cloth, or other suitable tlexible material, being made air-tight and provided with an intlating-tube, or, the size and form of the sack varying` of course, in accordance with the size and form of the mattress, cushion, or other article in which it is used. A series of stays, B, are disposed within the body of the sack, their ends being respectively cemented or otherwise suitably attached to the walls or top and bottom of the suck, as best seen at z in Fig. 4. The stays are preferably composed of two strips ot' stout but flexible rubber cloth about one inch in width, the strips being cemented together to form the body of the. stay, but opened outwardly at the ends where the stays are cemented or attached to the walls or top and bottom of the sack; but they maybe made ot' a single strip, or in any other suitable form, or of any suitable material which can be readily and properly cemented or secured tothe top and bottom or walls of the sack. A ring or re-enforce, O, having a slot or hole at its center adapted to receive the stay B, is passed on over either end of said stay before it is attached to the sack, and after the stay has been cemented or attached to thesack the rings are also firmly cemented or otherwise suitably attached to the same, and also to the out-turned ends, z, of the stay; but the rings may be omitted, if desired.

Disposed on the outer side of the sack, opposite either end of each ofthe stays B, there is an inverted button, l), provided with a metallic loop or eye, mf, the button being secured in position on the sack A by means of a rubber or rubber cloth disk or binder, E, having a hole at its center, through which the eye m of the button protrudes, the disk being ce- IOO mented or otherwise properly attached to the outer side of the sack. 'Ihe sack is incased in afcovering, H, composed of ticking, cloth, or other suitable material, the space between the sack and covering being stuied in the usual manner with hair, cotton, wool, or other suitable material, J.

In securing the upholstery in position on the sack A, the tufting-cords d are passed through the eyes m of the buttons D, thence through the hair or stuffing J, and secured to the tufts t. rlhe tufts may, however, be omitted and the cords attached to the covering or tied or knotted 0n the outside of the same.

It will be obvious that as the sack A is not perforated to receive the tufting-cords or up- 'holstering-twines, if the stays B or buttons D become accidentally detached there will be no danger of leakage.

It is deemed preferable to place the attaching-loops m directly opposite the stays B; but I do not confine myself to placing the loops in this manner, as they may be disposed in any convenientposition, and as many used as may be required in properly upholstering the sack. Neither do I confine myself to using the button D or eye m for securing the inner end of the twine d to the sack, as a ring, h, may be employed for this purpose, as shown in Fig. 5, the ring being secured by a loop, t, and Stay, l, cemented or otherwise properly attached to the sack. A plain loop, `Q/,may also be employed instead of the button D and eye m, said loop being likewise secured to the sack. I, however, deem the button D, having the eye m, preferable to the ring h or loop y,as it is strong and inexpensive.

The modification of the loop or eye shown in Fig. 7 is also preferable to those shown in Figs. 5 and G. It consists in a short strip or piece of rubber, rubber clothtorstout canvass, K, folded to form the upwardly-projecting flange r at its center, the iiange being provided with an eyelct, z, for receiving the tuftingcord d and the ends b ot` the strip, cemented or otherwise properly secured to the sack A. The eyelet may, however, be omitted, if desired, and the cord sewed or passed through the llange by means of a needle.

Myimprovement is also applicable to chairs, sofas, lounges, and all other work in which upholstered air-sacks are employed.

' The tube is provided with a cap for closing it air-tight, and is otherwise suitably constructed and inserted in the sack.

Having thus explained my invention, what I claim is- 1. In an upholstered air-sack, the combination of the following instrumentalities, to wit: an airsack provided with a suitable inflatingtube, stays disposed on the interior of the sack and connecting its walls or top and bottom, a body of hair or other suitable stufng material, twine or t'ufting-cords, and eyes, loops, or other suitable devices attached to the airsack for receiving and holding the inner ends of the tufting-cords, substantially as described.

2. The sack A, provided with the inatingtube fr, stays B, and eyes or loops m, substantially as and for the purpose specified.

3. The sack A, provided with the stays B, tube x, and buttons D, having eyes m, substantially as described.

4. As an improved article of manufacture, a mattress or cushion having the air-sack A, provided with the tube x, stays B, and eyes m, in combination with the covering H, stuff` ing J, and cords l, constructed, combined, and arranged substantially as described.
