. The invention is a cast frame for artificial limbs by which it is possible to :adjust the frame efficiently before the cast ,is made 7 The object of the invention is to provide a frame for making a cast for an artificial limb in Which the frame may readily beadjusted in position; V
Another object of the invention is toprovide' a frame for making a cast for an artificial limb by which the exact measurements for the artificial limb may be obtained.
Another object of the invention is to provide a cylindrical formin which the size and shape of the stump of a limb maybe cast, which has a readily adjustable. base.
And a still further object of the invention is to provide a readily adjustable cast frame which is of a simple and economical construction; V v
With these ends in view the,v invention embodies,ia cylindrical casing with an adjustable false bottom,- an adjustable rod upon whichthe casing is.mounted, a foot at the lower end'of the rod,- anadjustable opening attheupper end of the said casing a leather casing that may readily be. attached to the stump and a cast frame for the lower portion of the leg; r Other features and advantages of the invention will appear from the following deings, wherein:
Figure 1 is a view showin'ga framewith part broken away in which a cast is made for a limb amputatedabove the knee;
Figure-2 is a side View of the casing at the upper end ofFigure 1.
Figure 3 is a detail showing the means for attaching the cover plate to the upper end of thevcasing. r Y 4.
Figure 4 is a view of the casing somewhat similar tothatshown in Figure 1 which is particularly adaptable for making the cast of a leg in which the amputation is made belowthe knee joint. 7 i o Figure 5 is a view showing a casing similar to that shown in Figure 1 that isfparticularly adaptable for making the cast of an arm that is amputated above the elbow,

Inside of the ring18; is a: disc 22, the outer; edge of which :is provided with 9. .100
bottom which step joint to correspond with a similar joint in the ring 18 and this disc is mounted on a rod 23 which is screwed upon a vertical screw 24 at the upper end of the nut 19. It will be observed that by rotating the screw 24 the disc 22 may be raised or lowered as may be desired. On top of thedisc 22 is a circular plate 25 which is adjustably held by fingers 26. The lingers 26 are pivotally held in the plate 22 as shown at the points 27 and clamped in any suitable position by another disc 28, which is held to the rod-23 by a screw 29. It will be observed that by loosening the screw 29 the fingers 26 maybe readily. adjusted to change the diameter of the circular plate 25. 1
At the lower end of the screw 21 is a nut 30 which rests on the upper end of a tube 31 and it will be observed that by; screwing the nut 30 in one direction, the screw 21 may slide downwardly into the tube and by turning it in the opposite direction the screw may be moved upward. At the lower end of the tube 31 is a threaded portion 32, as shown in Figure 8, and on this-portion is a nut 33 which may be tightened or loosened to hold or release the tube on the rod 34. At the lower end of the tube 21 are slots 35 as indicated by the dotted lines in Figure 8 which will permit the'tube to bind around the rod. The rod 34 extends into a foot as indicated by the numeral 3G, and as shown in Figure 1. This foot may be of any suitable type or design and may be attached to the rod in anysuitable manner.
In the design shown in Figure 4 the device is provided with a casing 37 having an extension 38 similar to that shown in Figure 1 and at the upper end of the casing are sockets 39-into which outwardly extending bars 40 from the knee joints 41 may be placed as shown. The knee joints 41 are provided with upwardly extending bars 42 which may be continuous to the upper endof a leather casing 43 as shown, or may stop at the point 44 and be spliced with an upper section which will extend downward to a point 45 so that its length may be adjustable. The casing 43 may be held together by a strap 46 through eyes 47 and hooks 48, as shown, or in any other suitable. manner' In this design the foot is provided with side rods 49 which extend upward through sockets 50, 51 and 52 and which are held by a pin 53 on a chain 54. The upper end of the rod 34 is similar to that shown in Figures 1 and 9.
In the design shown in Figure 5 which is adaptable'fo-r an arm amputated above the elbow the casing 55 is provided with a ring 56 at the upper end which is similar to the ring 6 in the design shown in Figurel and flanges 57 which are similar to the flanges 3. On the interior of the casing is a false is indicated by the numeral ing62 may be strapped around the upper arm with the stump extending into the casmg so that the cast may be made in the casing 63. The interior of this casing 1s practically the same as that of the casing 2 shown in Figure 1, On the interior of the casing 62 are felt pads 64 as shown 1n dotted lines inFlgure 6. These pads are attached through the casing to the straps 42 tothe elbow joint 41 which is similar to that shown in Figure 4, and it will be observed that they extend into the hollow places above the elbow to assure a lirm grip. The casing 62 may be provided with buckles 66 by which it may be fastened on one side and may also be pro vided with eyelets 67 on the opposite side by which it may be laced. a
The special funnel shown in Figure 7 a is made with an'outwardly flaring flange 68 and a cylindrical section 69 which is provided with slots 70 to permit clearance for the sockets 39 on the casing 37, as shown in Figure 4. The lower end of the portion 69 may be curved as shown to fit the upperend of the casing 37.
t is understood that changes may be made in the construction without the spirit of the invention, one of which changes may be in the use of other means for attaching the casings shown in Figures 1 and 4 to the foot, anothermay be in the use of any other bination with the casing, and still another may be in the use of any other combination of the cast frames or casings than those shown.
Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent, is I 1. In a cast forming device of the class described, a cylindrical casing having an opening at one side with outwardly extending flanges at the sides thereof, means for holding the flanges together, adjustable means for partially closing the opening at the upper end, a horizontal partition midway of the said casing, said partition being made in sec tions, means for ad ustmg the position of the sections in relation to each other, means for ad usting the positlon of the said horizontal partition, a stem extending downward from the lower end or" the casing attached to the lower end thereof and also to the said horizontal partition, a foot at the lower end of the stem and means for readily adjusting the length of the said stem.
2. In a casting device of the class dedeparting from foot than that shown in com comprising a plurality of sections,
scribed, a cylindrical casing having a flanged opening at one side, means for holding the flanges together, an adjustable closure at the upper end of the cas ing, a horizontal partition in the said casing, means for adjusting I the position of the said partition, said partition being made in sections and means for adjusting the position of the said sections in relation to each other.
3. In a. cast frame for artificial limbs, a cylindrical shell With a vertical opening in one side thereof, means for holding the edges of the shell together at the opening, a horizontal partition in said shell, said partition means for adjusting the positions of the different sections independently to fit the lower end of a stump placedtherein, an expanding band on the upper side of the said partition, and means for adjusting the position of the said band.
In testimony whereof I affix my signature.
