    Winchester's Improvements in Splints. Figures 6, and 7, represent a modification in tlie construction of the knee joints ; D, being made similar to the ordinary rule joints: and Figures 8, 9, and 10, are also modifications in the hip-joints E, and are of a construction analogous to the ball and socket joint. Either 5 of these joints allows of all the necessary motion of the hip, without deranging the other parts of the splint. ? Figures 11, and 12, are respectively plan and edge view of a portion of a splint composed of thin plates of metal, lined or covered with leather or other suitable material, and connected together by the 10 joints <2, a. Should it be desired, the plates forming the pads may be made of perforated metal, or of the shape represented in Figure 13. Figure 14, shews the plan I adopt in forming the straps to fasten the splint upon the part to which it is applied. Between the parts A, and B, of the strap, I insert a strip or piece of vulcanized india rubber, or other suitable elastic material a, so that the strap will expand and admit of any swelling that might take place. The ends of the pieces A, B, have eyelet holes through which a string may be laced when it is required to prevent or to limit the expan¬ sion of the strap. 20 Figure 15, represents a mode which I adopt in order to take up any looseness in the straps or to dispense with the use of buckles. A, is one of the pads in which is cut the slot a, through which one end of the strap is passed, the other end being fixed to a stud pin. B is a small roller turning in the brackets 6, h, and on which the 25 end of the strap is wound. C, is a ratchet wheel on one end of the roller, into the teeth of which the paul D, takes and prevents the roller from running back. When it is desired to tighten the strap, all that is requisite is to turn the roller the required number of teeth of the ratchet-wheel. 30 And having now described the nature of my said Invention, and the manner in which the same is to be performed, I declare that what I claim is, the manufacture of adjustable splints composed of several pieces of wood, metal, or other suitable material, united by
