INVALID KNEE-REST.

Specification of Letters Patent. Application filed March 17, 1906. Serialllo. 306.610.

Patented Sept. 4, 1906.

To all whom, it may concern.-

Be it known that I, LILY H. CowAN, a citizen of 'the United States, residing at Durham, in the county of Durham and State of North Carolina, have invented new and useful Improvements in Invalid Knee-Rests, of which-the following is a specification.

' This invention relates" to invalid knee-- rests, the object of the invention being to provide a knee-rest especially adapted to the requirements of surgeons, nurses, and physi cians in hospitals and at other places, the improved knee-rest being adapted to be placed upon the bed to support the knees and lower portion of the body to relieve patient s position'after operation, the device also embodying means for supportin bedclothes and holding the foot or feet of t e patient at" the necessary elevation to prevent hemorrhage after amputation, &c.

With the above and other ob ects in view the nature of whichiwillmore fully appear as the description proceeds, the invention consists 1n the novel construction and combmation of parts hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a side elevation of the knee-rest, showing one method of using the same. Fig. 2 is a plan view thereof. Fig. 3 is an enlarged side elevation of the knee-rest shown used as a prop for the patients back. Fig. 4 is an enarged fragmentary side elevation showing the connection between the hinged members or sections of the rest. Fig. 5 is a detail sec' tion showing interchangeable supportinglegs and the manner of connecting the same to the body of the rest.

The knee-rest contemplated in this invention comprises an oblong frame composed of two sections, an upper section 1 and a lower section 2, the said sections being of suitable length and connected together at their meeting ends by hinges 3. The lower section 2 consists of an open rectangular frame over which is stretched a covering 4 of woven fabric, such as cane-seating, while the upper section 1 has one portion thereof provided with a covering 5, the end portion of the section 1 being left open for a purpose which will hereinafter appear. The sections 1 and 2 are further connected by means of braces6, ar-.

ranged at opposite sides thereof and pivotally connected to one of the sections, as

with notches or teeth 9, adapted to engage pins or projections'lO on the other section of the knee-rest, whereby the two sections of the knee-rest may be held at any desired angle with relation to each other, as clearly shown in Fi s. 1, 3, and 4. Connected pivotally to the farther end of the section 2 is a bail-shaped frame 11, embodying the arms 12, the end cross-bar 13, and provided with one or more intermediate cross-bars 14'. If desired, however, the cross-bars 14 may be omitted. Said frame 11 -is pivotally connected to the section 2 of the knee-rest at the points 15, so that it may be swung to stand either vertically, as shown in Fig. 1, or folded down flatwise against the section 2, as shown in Fig.2. This adjustable frame 11 is adapted to support the bedclothing at an elevation, so as to relieve the feet of the patient from the weight of the covering in case either foot is injured. The outer corners of the section 2 of the knee-rest are also provided with threaded sockets 16, ada ted to receive the reduced and threaded ends 17'of one or more sets of interchangeable supporting-legs 18 of different lengths, whereby the frame-section 2 may be supported at any desired elevation above the bed or other surface upon which.

porting-legs of suitable length. The con- I struction of the upper section 1 of the frame also adapts suitable a pliances to be laced under the patient whi e lying within t e bed and without removal therefrom, thus greatly facilitating the handling of the patient.

I claim 1. A knee-rest embodying a plurality of sections having a jointed connection with each other, braces for adjusting and maintaining the angle between the sections, and detachable legs for supporting one of the sections at a suitable elevation.

2. A knee-rest embed ing hinged sections, means for adjusting said sections at an an le to each other andmaintaining such angle, and a bedclothes-supporting frame having a jointed connection wlth one of said sections and adapted to be positioned at any angle with respect to said section. I

3. A knee-rest embodying hinged sections,

pins on one section, and braces pivotally connected to the adj oininn' section and provided with notches or shoulders adapted to engage the said pins and hold the sections at the desired an 'le to each other, substantially as describe 4. A knee-rest embodying hinge-. sections, means for adjusting the angle of said sections and maintaining said angle, and interchangeable supporting-legs of different lengths a 1O plicable to one of the sections, substantial y as described.

In testimony whereof I aflix my signature in presence of two Witnesses.
