LIME-SETTING- DEVICE.

Specification of Letters Patent.

PatentedAug. 3, 1915.

Application filed September 22,1914. Serial No. 862,916.

To all whom it may concern:

Be it known that LMAX SoHNUe, a citizen of the United States, and a resident of Bonduel, in the county of Shawano and State of Wisconsin, have invented certain new and useful Improvements in Limb-Setting Devices, of which the following is a specification. Y

My invention relates to the setting of fractures, as of the arm, and the main object is to provide a simple though positive device for drawing the fractured members of a bone into normal alinement, and for maintaining the same therein.

A further object is to provide such a device which is adjustable to meet varying conditions, as for children or adults, and to place the limb under desired tension for setting fractures, and thereafter for knitting of the bones; and a further object is to pro vide such a device which is of very compact form, and which may be made foldable, for storage in a physicians bag.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated by the same reference characters in each of the views, and in which Figure l is a view of a present preferred form of embodiment of my invention, in use; and Fig. 2 is a view thereof, detached.

In the form illustrated, I provide a how 5 of band metal inwardly bent at its upper end and connected, permanently or detachably, with a ring 6 having inwardly directed, side, screws or clamps 7, and in turn riveted or otherwise connected with a vertical portion 8 of the bow, said how being bent to form a member 9 having a threaded bolt 10 therein directed toward the ring 6, the inner end of said bolt having a swiveled eye 11 thereon, and the body portion 12 of said bow is inclined, thereby giving the appearance of a triangle to the same.

In practice, the broken limb is passed through the ring 6 and said ring moved up into firm contact with the arm-pit, when the humerus is broken, the clamps 7 tightened to hold the device in position, a bandage passed around the forearm in the position of the elbow and secured to the swiveled eye 11, after which tension is applied by turning the bolt 10 until the fractured ends are brought into alinement, at which time the arm may be splintered and bandaged with my device still in position, and it may be so maintained to exert a constant strain on the injured limb.

While the device is shown as used for the upper arm, it may be just as readily used for the forearm if the fracture has occurred'in the ulna or radius, and the device may also be used for the fibula and tibia.

I prefer to provide the clamps 7 with padded heads, and I will also pad the inner side of the lower portion of the ring and the vertical portion 8 of the bow, as shown at 18 where it comes in contact with the.

body of the patient, a bandage 14 being employed to insure such contact and to maintain the device in position.

It will thus be seen that I provide a device having a rigidbody portion, means for connection with a limb at each end thereof, and means for placing the limb under tension to aline the members of a fractured bone, said device not interfering with the dressing, splinting, or bandaging of the limb. It will be obvious that I may make other forms based, upon this principle, without departing from the spirit of my invention or sacrificing its advantages, within the scope of the following claim.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is z A limb setting device, comprising a rigid frame consisting of a main portion having two arms bent at an angle thereto, a ring at the end of one arm, means in operative connection with said ring for securing the same to one end of a limb, adjustable means on the other arm for connection with the other end of said limb, and a brace member connecting said ring with said last named arm, to insure rigidity of said arms with respect to said main portion.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
