nosrrran nan original application filed August 2.

The invention relates to hospital beds and it is particularly directed to an overhead frame or structure for such beds by which to support and secure extension upon a fractured limb, this application being a div1sion of my application Serial Number 296,930 filed August 2, 1928, which has resulted 1n Patent N umber 1,823,890, dated Sept. 22, 1931.

Devices of this general type are known in the art as overhea frames and are principally used 1n cases of limb fractures. It is highly important in many such cases to be able to obtain abduction of the limb at any angle. For instance, if the upper bone of the leg be broken near the hip the short upper section Wlll have its lower end drawn forcibly outward by the action of the muscles. The angle which this short upper section assumes to the body differs in different cases due to physical differences in the patients and to the position and character of the fractures. In all cases, however, it is imperative, if the bone is to knit with the broken parts in true alignment as it should, that abduction be had on the lower part of the upper leg in a straight line with the upper section of the broken bone. Hitherto it has been customary to use an overhead frame in which the members had no adjustment for the purpose of obtaining such direct line adjustment and to strap, tie with rope or otherwise secure a temporary member to the frame in an effort to get a part of such member in a position so that a pulley could be attached thereto in position for straight line abduction. Settin g the crudeness of such apparatus aside there always existed in such devices the danger of slippage with consequent injury to the patient. As above mentioned the upper part of the bone deflects laterally and usually this lateral deflection is accompanied by anterior deflection. It is, therefore, necessary that abduction should be had in most cases in an outward and upward direction from the patient on the bed. Furthermore, if the patient moves or is moved the apparatus should be capable of easy and quick adjustment to his changed position.

The principal object of the present invensuspension and extension 1923, Serial No. 296,950, new Patent Bio. 1,823,880, dated eptember 22, 193i. Divided and this application filed. November 1,

tion is to provide a novel overhead suspension and extension frame for a bed wherein certain of the members are so connected as to be capable of being arranged in all positions necessary to obtain straight line abduction on a broken limb, the connections between the members being such as to readily lend themselves to quick adjustment both angularly between the connected members and longitudinall along the gonnected members.

T e invention is illustrated in the accompanying drawing in which Q Fi re 1 is a perspective view of a bed having t e invention applied thereto; Fig. 2 a plan view of one of the clamps by which the posts or standards of the rack or frame are clamped to the bed posts; Fig. 3 an elevational view, partly in section, of one of the pivotal supports of the frame and Fig. 4 an elevational view of another of the pivotal supports.

In the illustrative embodiment of the invention the bed is formed, in the usual manner, of the head 1, foot 2, and two attachable side rails 3, 4. Further detail of the bed construction is not essential to this divisional application, suflice to say that the mattress carrying cot 10 is suspended on the bed frame for raising and lowering.

The overhead structure or frame comprises four posts or pipes 29 adapted to be attached to the bed posts by the clamps 30, the stem 31 of each of which clamps extends through the post and is held in place by a nut on the stem. Nuts 32 on the arms 33, 34 of the clamp hold the plate 35 firmly against the inner face of the bed post, the plate being loose on the said arms.

The jaws 36 are pivoted to the caps 37 that are threaded on the upper ends of the posts 29. The jaws support the rods or

pipes

38 and 39 in longitudinally adjusted position, set screws 40 in the jaws securing the same to the rods or pipes. Upon the rods or

pipes

38 and 39 are adjustably mounted any number of jaws 41 each of which is pivoted to a similar jaw 42, a set screw 43 in the jaw 41 being adapted to secure said jaw to the rod or pipe in any position thereon. The jaws 42 receive the rods or pipes 44 and similar double jaws 45 may be mounted on either or both rods or pipes 44 and adjustably support another rod or pipe 46. The rods or pipes 44 may be set at any angle relatively to the longitudinal axis of the bed so that the de- 5 sired extension of the limb may be secured, the usual )ulleys being mounted on the rods or pipes w ierever desired, and the usual cords with weights thereon being passed over the ulleys and connected to the splint or to thee not shown. A wide range or adjustment 0 the extension device is thus possible, the swivel members permitting a multiplicity of variations and adjustments of the frame members. What I claim is:

An overhead suspension and extension frame for hospital beds including a set of four corner posts each adapted to be connected to a respective leg of a bed, yoxes on top of said posts, cross-bars each resting in the yokes of a pair of the posts at a respective end of the bed, means to secure said cross-bars in said yokes, swivel members slidably mounted on and extending upwardly 95 from said cross-bars and having their upper portions constituting yokes, means to secure said swivel members in adjusted position on the cross-bars, a longitudinal bar resting in swivel yokes on respective cross-bars, means to secure the longitudinal bar in said swivel yokes, other yokes slidably mounted on the longitudinal bar and extending upwardly therefrom, means to secure the last mentioned yokes in adjusted position on the longitudinal bar, an extension bar resting in the last mentioned yokes and projecting beyond the end of the longitudinal bar to support a pulley, and means to secure the extension bar in said yokes.

In witness whereof I have hereunto subscribedmy name.
