AIR MATTRESS OR ou'sH'IoN'.

SPECIFICATION forming part of Letters Patent No. 624,638, dated May 9, 1899.

Application filed August 30, 1898- T0 aZZ whom it may concern.-

Be it known that I, EUGENE FOURN'IER, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented new and useful Improvements in Air Mattresses or Cushions, of which the following is a specification.

My invention relates to improvements in that class of mattresses that is capable of being inflated and deflated; and the object of my improvements is to provide an article of hated and when inflated will be comfortable, in that it will readily conform to the different positions taken by the user and will retain the air under all conditions to which it would be normally subjected. The manner forth in the accompanying drawings, which form a part of this application, in which Figure 1 is a perspective view of my invention in the form of a mattress with a portion removed to show the anchors or fastenings. Fig. 2 is a cross-section of the mattress, and Fig. 3 is a sectional view of the fastening or anchoring device in detail on a large scale.

Like letters indicate like parts in the several views.

My invention consists generally of a rubher bag or like device adapted to be. inflated 1 by air introduced through a valve and prol vided with a covering of ticking or other textile fabric and means for anchoring or quilting the top and bottom.

By reference to the drawings it'will be seen that B represents a mattress rectangular in form and made from sheets of rubber cloth suitably secured together to form an air-tight body and with a suitable valve at one end for introducing the air. Entirely enveloping the rubber mattress is a covering A, which is composed of ticking or other suitable textile fabric and conforms in shape to the mattress B.

The covering A is held in place on the mattress and the latter is given a flat, oval, or

are placed at intervals throughout the body of the mattress. These stays are composed of a cylindrical metal disk 0, formed with a downwardly-extending hub portion 0' and a countersunk face 0 The hub C has its Serial No. 689,823. (1% model.)

lower portion flattened and perforated for the receptionof a cord, chain, or spring. The upper part of the hub G is bored longitudinally and the bore threaded to receive a threaded bolt 0, having a fiat head 0. The bolt 0 is also bored longitudinally and the bore threaded to admit a screw D. v Between the countersunk face of the disk 0 and the head of the screw 1) is interposed a flat washer 0 The stays consist, further, of chains, cords, or springs (l, which are attached to the flat portions D of the disk 0.

In applying the stays I perforate the rubber sheet B, place around the perforation a washer c, and insert therethrough the bolt 0, pressing it firmly down onto the washer. ,I then screw the threaded hub portion of the disk 0 onto the threaded part of the bolt 0 until the washer and rubber are forced into the countersunk face of the disk 0.. The

ticking or outer fabric A is then perforated and the screw D. inserted therethrough and screwed into the internally-threaded shank of the bolt 0 until the head of the latter, is firmly pressed on the head of the bolt 0 and the washer 0, thus securing a tight joint between the rubber sheet B and the cover A and adding to the effectiveness of the closure of the openin gin the rubber sheet. It will be noted that the screw D has a flat head which is providedon its upper face with a covering of cloth. When the disks, washers, and screws have been secured in the manner described at proper intervals throughout the top and bettom of the mattress, the opposing hub portress any desired contour by giving to the parts (1 different lengths.

Interposed between the top and bottom sheets of rubber is a sheet of cotton cloth E or other suitable material, which is secured to the end pieces e of the mattress. The

function of the sheet E is to prevent the two In the a sheets of rubber from sticking together when the mattress is deflated and rolled up for storing or transportation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a device of the character described,

the combination with an elastic-fabric bag, of stays consisting of metal disks having a countersunk face and a hub portion, and means for forcing the elastic fabric into the countersunk face of the disks, and means for connecting the opposite hub portions, substantially as set forth.

2. In a device of the character described, the combination with an elastic-fabric bag, of stays consisting of metal disks having a countersunk face and a threaded hub portion, a bolt for forcing the elastic fabric into the countersunk face of thedisk, and means for connecting the oppositely-extended hub portion, substantially as described.

3. In a device of the character described, the combination with an elastic-fabric bag and a non-elastic-fabric cover for same, of stays consisting of metal disks having a countersunk face and a threaded hub portion, an externally and internally threaded bolt for forcing the elastic fabric into the countersunk face of the disk, a screw adapted to enter the bolt and secure the non-elastic fabric in place, and means for connecting the oppositely-extended hub portions, substantially as described.

4. In a device of the character described, the combination with an elastic-fabric bag, and a non-elastic cover for same, of a sheet of cloth interposed between the opposing sides of the bag, and means for staying the opposing sides of the bag,substantially as described.

5. In a device of the character described, the combination with an elastic-fabric bag, a non-elastic coverfor same, a sheet of cloth interposed between the opposing sides of the bag and stays consisting of metal disks having countersunk faces and threaded hub portion, means for forcing the elastic fabric into the countersunk face and means for connecting the oppositely-extending hub portions, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

EUGENE FOURNIER.
