SPECIFICATION forming part of Letters Patent No. 716,752, dated December 23, 1902.

Application lefl January 9, 1902. Serial No. 89,088. (No model.)

To a/ZZ whom, it may con/cern) Be it known that I, LUCY B. PHILLIPS, a citizen of the United States, residing at Bridgeton, in the county of Cum berland and YStatel of New Jersey, eXecutriX` of the estate of WILLIAM H. PHILLIPS, late acitizen of the United States, residing at Bridgeton, in the county of Cumberland and State of New Jersey, deceased, (as by reference to the duly-cer.-` tified copy of letters testament hereto annexed will more fully appean) do hereby declare that WILLIAM H. PHILLIPS invented a new and useful Air-Cushion, of which the following is a specification. Y

This invention relates to air-cushions adapt. ed to be applied to various uses.

The object of the invention is to provide a cushion composed of sections, which are so connected as to avoid contact of the person using them with the connecting means.

Figure l of the accompanying drawings represents a bottom plan view of two cushionsections, showing this improved method of connecting them. Fig. 2 represents an end elevation thereof.

The same reference-numerals indicate corresponding parts in both figures.

In the form illustrated in Figs. l and 2 two cushion-sections l0 and 20 are shown provided with flaps ll and 2l, extending along the bottoms thereof near their inner edges, and these flaps are provided with longitudinally-alined perforations, as 12 and 22. A suitable lacing-cord 30 is threaded through the perforations, as l2 and 22, in the usual manner and the ends thereof tied together in abow-knot or connected in any desired manner, said cord operating to hold the cushionsections in parallelism and against separation underimposed weight. The cushion-sections are preferably provided with loops or tabs, as 13 and 23, which may be attached to the cushions at any desired point, preferably the corners, and are adapted to be used as fastoning means for attaching the cushion to the bed, chair, or other article to which Yit is desired to attach it. These connecting devices do not extend the entire length of the sections, but terminate at a point near the opposite ends thereof, whereby all-possibility of the connecting device coming into contact with the body of the person is avoided, for if the connecting-web or the lacing were carried to the eXtreme-ends of the cushion-sectionsV it would follow the curve Vof the back andcome so high as to touch and annoy the patient, while the said cushion-sections being connectedfor the greater part of their length are prevented from separating too far apart when the patients weight is applied on the 6o tops thereof. More perfect ventilation is provided, as the cushion-sections are separated throughout their entire length, and free circulation of air permitted. Each section is preferably provided with a nipple-valve 14 65 and 24 at one of the outer corners thereof, thereby permitting ready access to the sections for the purpose of inflation or deiiation without disturbing the patient upon the cushion and permitting equal or unequal inflation, 7o as may be desired. y

The principal point of importance in this invention lies in the point of attachment of the connecting aps or web to the bottom of theY cushion sections, which gives all the depth possible to be obtained, as the connecting means lies iiat on the bed, and the height of the surface upon which the patient lies may be regulated at will by the degree of iniiation of the cushion-sections.

The lacing allows the two sections to be disconnected completely for use as single pillows or pads, permits replacement of one part of the cushion in case of injury without affectin g the other part, and allows adjustment of the sections at various distances apart to accommodate different patients.

An air-cushion comprising two rectangular pillow-shaped sections, a flap secured to the 9o under side of each section and extending parallel with one edge thereof, and a lacing associated with the flaps for holding the sections parallel in use.

In testimony that l claim the foregoing as 9 5 the invention of WILLIAM H. PHILLIPS I have hereto affixed my signature in the presence of two witnesses.

v LUCY B. PHILLIPS, Exec/atrio@ of the estate of William H Phillips,

deceased. Witnesses:

N. B. OGDEN, JAS. S. WARE.
