APPARATUS FOR HOSPITAL BEDS Filed Sept. 21, 1933 I5 Sheets-Sheet 5 ATTORNEY Patented Aug. 11, 1936 UNITED STATES PATENT OFFlCE 7 Claims.

The present invention relates to apparatus or appliances for use with hospital or invalid beds, and aims to provide a novel and efficient apparatus which may be conveniently positioned in proper relation to such beds for the purpose of enabling the invalid to be supported invarious positions, or for facilitating other operations which may become necessary in the treatment of the patient.

Accordingly, I have devised an apparatus which may be conveniently attached to the frame of the bed, and adapted to form a support for various appliances in suitable overhead relation to the bed for facilitating the proper handling of the patient or enabling him to make such use of the appliances as may be desired. Where the apparatus is designed for attiatchment to the head and foot frames of the bed, suitable provision is also made for convenient longitudinal adjustment of s the apparatus for properly accommodating the length of the bed. p

It is also sought to provide apparatus of this character which may be either attached to the ends of the bed, or supported at either or both ends independently of the bed, whereby the apparatus may be readily moved into and out of overhead relation to the bed, as by a bodily movement thereof or by swinging the apparatus pivotally about one of its connections with the bed.

A further feature-of the improved construction resides in the provision of a means of supporting the patient, together with connections whereby the patient may be either liftedvertically,'or turned or rolled from one side to the other upon the bed, as for facilitating the change of bed linen, or the like.

With these various principal objects in view, as well as minorobjects as will appear in-the course of the detailed specification, the invention will now be described by reference to the accompanying drawings, illustrating a suitable form of embodiment of the improved details of construction, after which those features and combinations deemed to be novel will be particularly set forth and claimed.

Referring now to the drawings in detail, the

- apparatus is illustrated as comprising a main longitudinal frame member I for the mounting of 15 various appurtenances in overhead relation to the bed and adapted tobe supported for this purpose by upright frame members at the head and foot of the bed, respectively. The frame member Ill is shown as a square tubing, the head end of which 20 is'secured by a pin l2 to a short sleeve it which is threaded into a 1' ii at the upper end of a tubular post 16. The lower end of this post. rests upon a washer 11 carried by an adjusting nut l8 having suitable operating handles IQ for tul hing 25 the nut upon a tubular screw 20 which prclects up within the post it and has its lower end fitted to the upper section of a split clamping bracket. This bracket comprises the hinged sections 22 connected by a pivot pin 23 and provided with 30 swivel bolts 24 and nuts 25 whereby the bracket may be conveniently clamped to the top of the head frame 26 of the bed.

The opposite or foot end of the frame member I0 is fitted with an internal sleeve 28 threaded 35 for a screw 30 secured by a pin II to a short section of tubing 32 which is mounted slidingly in a T I! at the upper end of the tubular post It which is of a suitable length for supporting the same upon the top of the foot frame 26' of the 40 bed by means of a screw 28 and similar bracket structure, as in the case of the post it.

Each of the bracket devices 22 is provided with a supp rting spring 35, the lower end of which carries a nut 36 or the like for retaining en- 45 gagement with the upper bracket section, said spring extending up through the screw 2. and having its upper end provided with a retaining washer 31 for engagement with the upper endofthepost ltorliflasshowninl'lgureso 5. By this means the bracket structures are prevented from becoming casually dropped during the assembly of the parts of the apparatus in place, or in the'adjustment of the same, thus guardingagainstanyofthepartsfallingonthe 55 floor, or accidentally upon the bed, or the patient himself in case the bed is occupied.

The outer end of the tubing 82 is fltted with a suitable hand adjusting nut 48 adapted to shoul- 5 der against either the T l5 or an interposed cross member 4| clamped by a. set screw 42 to said tubing and carrying a pair of pulleys 48. 0peration of the nut 48 of course serves to accommodate the posts l6 and [6 to the particular 10 length of the bed, said nut cooperating with the collar 44 and its set screw 45 at the front of the T I! for securing this adjustment.

Each of the posts l6 and I6 may be provided with a horizontal arm 46 attached to the post by means of an adjustable split clamping bracket comprised of hinged clamping sections 41 (similar in all respects to the bracket 22). Each of the arms 46 carries a pulley 48 suspended from a screw eye 48 adapted to be secured in any one of a series of openings Si in said arms (see Figure 2),

which are also provided with rope or cable securing cleats 52.

The longitudinal member ID also serves as a support for a series of cross arms 64 having the 25 square sleeve portions 85 adapted to be adjustably secured by set screws 56 at any desired position along the member ID. The ends of the cross arms are provided with pulleys 51 for cables 68 and also with slot openings 58 for the support of straps such as 68 and 8|, as well as for reeving of the cables 58 when desired, as represented in Figure 1.

Provision may be made for the support of the apparatus at the head of the bed independently of the bed frame, as by means of a standard 68 supported on a base 64 provided with rollers 65,

the top of said standard having an elbow 66 attached by a sleeve 61 to the T I! at the top of the upright it, as illustrated in Figures 2-4. Or, if preferred, a shorter standard 68' may be provided (Fig. 7), having a collar 68 for accommodating the complete adjustable post structure I 82l between said collar and the elbow 86, as

represented in Figure 7, which view illustrates similar provision for the support of the other end of the apparatus independently of the foot of the bed by means of a still shorter standard 68", collar 88' and upper elbow 68', whereby the complete apparatus is supported altogether independently of the bed.

' This allows the apparatus to be rolled to and from the bed, as is preferable under some conditions, and moreover with onlyvone end of the apparatus thus supported independently (as with the head end as shown in Figures 2 and 3), the apparatus may be swung upon its roller support, with the foot post as a pivot, into a lateral position as illustrated by the broken lines in Figure 3, forallowingthebedlinentobechanged,orthe carrying out of other operations as desired.

In the use of the apparatus as above described, it will be understood that theapparatus may be supported either altogether independently of the bed. or by attachment of either or both ends to 68 the bed, and in the latter cases the proper vertical adjustment of the supporting posts I8 may be quickly and conveniently made by means of the nuts 18 for raising or lowering the ends of the longitudinal member-i8, in addition to which the 70 necessary longitudinal adjustment is also readily made by turning of the nut 48 and clamping the. set collar 44 as already indicated. Someof the" pelvic band 18 attached to cables 88 suspended from the pulleys 81 carried by the cross arms 64 (Figure 2); the application of a tractor or tensioning action to one of the patients limbs by a cable 62 attached to the foot and operating over 5 a pulley 48 carried by one of the arms 46, or one of the pulleys 48 carried by the arm 4|, the pulley in either case being so positioned as to dangle the tensioning weights 12 entirely outside or beyond the foot of the bed, as represented in Figures 1 10 and 2; the attachment of a strap 60 or Si in convenient position for lifting purposes; or the use of a cable for the support of the patients arm in any predetermined position by means of the arm 46 and its pulley 48, said arm 46 and pulley 15 both being readily adjusted in an obvious manner. It may be further noted that the patient may be supported by a plurality of bands sus pended from the several cross arms 54, so that if the apparatus is supported at only one end by 20 one of the roller standards, as 63, the patient may be lifted and swung entirely off the bed by a movement of the apparatus as represented by the broken lines in Figure 3.

Still another operating feature is illustrated 5 by the construction shown in Figure 6 of the drawings. Upon the post i6 is mounted a bracket member having a sleeve portion 8| secured to the post by set screws 82 and also formed with end bearings 83 for journaling a 30 shaft 84 carrying pulleys 85 for receiving the ends of the cables 58'. To the intermediate portion of the shaft 84 is secured a ratchet wheel 81 engaged by a pawl 88 pivoted at 90 to the top margin of the bracket member 80, and one end of the 35 shaft 84 is provided with a suitable handle 92 for the simultaneous rotation of said pulleys 85. The upper ends of the cables 58 already referred to may be connected by suitable splicing to the cables 58, and their lower ends attached to a 40 series of the bands 18, or to the sides of a sheet 84 on the bed, having suitable eyelets 95 for convenient attachment to the cables, whereupon the operation of the pulleys will serve to produce a uniform lifting movement upon all the cables for 45 raising the patient up of! the bed. Or, as an important alternative operation, the cables may be wound in opposite directions on the pulleys 86. as represented by the broken lines in Figure 6 with reference to one of said pulleys, whereby the 50 patient may be comfortably moved by a turning or rolling movement to one side of the bed, as a convenient method of handling the invalid, as in changing the sheets of the bed.

A modified form of attachment for connection 55 with the bed frame is illustrated in Figure 8, where the lower portion of the bracket is formed in two separately hinged sections 22' for the purpose of clearing a spindle or other portion II of the bed, where such portion would otherwise 60 interfere with the proper positioning of the post l6.

It will thus be apparent that a very efficient, practical and useful apparatus is provided for the various purposes for which such equipment may 65 be employed for invalids conflned to hospital beds, and that the same may be adjusted and operated with great facility and a maximum degree of comfort to the patient. I am aware that apparatus of the character described is not 7 broadly new in equipment of this type. but the various improvements and combinations defined in the following claims are believed to be new, and I accordingly desire to be understood as reserving the right to make such changes or mod- 75 iflcations as may fairly fall within the spirit and scope thereof.
