ADJUSTABLE CUSHION Filed Nov. 14, 195e if' L INVENTO L am W0/ 46e ATTORNEY Patented Feb. 15, 1938 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to an adjustable cushion and more particularly to an adjustable cushion to be used. in connection with piano seats.

Piano benches or seats are designed primarily for adults and are always too low for children sov that resort is usually had to telephone directories, sofa pillows, and the like, as cushions to raise the child to proper position. 'I'he diculty is that these makeshifts seldom are of the right height so that the child is seldom placed in the proper position for playing. The awkwardness of sitting upon an improvised seat induces nervous fatigue and minimizes the childs ability to concentrate on the matter in hand. The old piano stool with its adjustable seat is a thing of the past, and inasmuch as it was an unstable and unsatisfactory seat, it has been largely replaced by piano benches in connection with which the instant cushion is adapted to be used.

One object of my invention is to provide an adjustable cushion adapted to properly position children at the piano.

Another object of my invention is to provide an adjustable cushion for use by children of various ages and for use by -growing children.

Other and further objects of my invention will appear from the following description.

In the accompanying drawing, which forms a part of the instant specification and whi-ch is to be read in conjunction therewith and in which like reference numerals are used to indicate like parts in the various views;

Fig. 1 is a perspective view of a cushion containing one embodiment of my invention, with parts broken away.

Fig. 2 is a perspective view of the cushion shown in Fig. l with the parts in position for the insertion or removal of a leaf.

Fig. 3 is a sectional view taken on the line 3 3 of Fig. 1.

In general, my invention contemplates the provision of a cover of flexible material, such as v fabric, leather, imitation leather, or the like, into which a plurality of leaves or inserts may be placed or removed to obtain cushions of various heights.

More particularly, referring now to the drawing, a flexible cover l made of fabric, leather, imitation leather, or the like, is formed by sewing the fabric into the shape of a bag or sack, the mouth of which is adapted to be closed by a draw string 2. Into the cover member is adapted to be inserted a plurality of leaves or inserts 3, the upper one of which 4 is made of sponge rubber, felted material, or the like, to provide a comfortable and resilient or yielding seat. Each of the leaves 3 is made the form of the nish'ed seat and may be of any suitable material, as, for example, pressed wood libres or the like. In practice, I have used leaves made of celotex, which is the trade name for a synthetic boardlike material made of pulped wood fibres pressed into shape. Each of the leaves may be of any suitable thickness. In general, thicknesses from one-half to three-fourths of an inch will suffice, and in practice six leaves or inserts are all that need be used. In order that the cushion present a neat appearance, as shown in Fig. 1, I provide an insert member 5, the center of which is cut away, as can readily be seen by reference to Figures l and 3. The hollow portion formed by the insert above and the insert below the member 5 forms a chamber for the reception of the seam 5 and the draw string 2.

After the desired number of inserts have been placed in the bag or cover l, the draw string is pulled tight and is wrapped circumferentially around the cover and pulled tight so as to draw the excess material inwardly into the space formed by the member 5, it being understood that the draw string 2 is made of unusual length to permit it to be wrapped several times around the circumference of the cushion. When the draw string has been wrapped tightly, the seam 6 and the string will lie in the hollow space formed by the member 5, as will be clearly seen by reference to Fig. 3. In this manner, the cushion will present a at and neat appearance, as shown in Fig. l.

The operation of the article will be clearly understood from the foregoing description. When the child is small a maximum number of inserts or leaves 3 will be inserted, with the top leaf 4 made of resilient material uppermost. As the child grows, the height of the cushion may be reduced by simply removing inserts or leaves 3. It will be seen that I have accomplished the objects of my invention and have provided an adjustable cushion for use with piano benches, or the like, enabling children to use seats designed primarily for adults.

It will be understood that certain features and sub-combinations are of utility and may be employed without reference to other features and sub-combinations. This is contemplated by and is within the scope of my claims. It is further obvious that various changes may be made in details within the scope of my claims without departing from the spirit of my invention. It is, therefore, to be understood that my invention 2 is not to be limited to the specific details shown and described.

I claim:

l. A cushion comprising in combination a flexible cover member in the form of a sack having an open end, a plurality of plates each of less area and height than the sack, said plates set within said sack above one another loosely in substantial alignment and adapted to be selectively removed therefrom to reduce the height of the cushion, securing means for said sack including means for closing said open end and an elongated flexible member positioned circumfer-Z entially around the cushion intermediate the upper and lower faces thereof adaptedto draw in surplus material of said cover member between adjacent plates.

2. A cushion as in claim 1 in which one of said plates is formed with a central opening, said elongated flexible member being adapted to draw in surplus material between adjacent plates and into said opening.

LETA WALLACE.
