Figure 13 is a side elevational view of the device the anview on the line 8-8 of view on the line 9-9 of the line 10-10 4 adapted for use on neck structures.

Referring to the drawings; wherein like numerals designate like parts, it can be seen that the apparatus consists of the base 5 from which the socket member 6 extends. The socket member 8 receives the lower end of the tubular upright I in which slides the lower portion of the post 8.

A collar 9 is'provided around the upperpportion of the upright I and a set screw I0 is provided in conjunction therewith for fixing the said post 8 at the proper elevation.

A hub-like structure I i is provided at the upper end of the post 8, the same having an inwardly tapering pocket at each side thereof. The bottom of the pocket'at the back side of the hub structure H has the threaded pin i2 extending therethrough and through the annular and ta-. pered plug i3, which has a central opening for receiving the pin l2. A knob-like nut I4, is feedable on the pin l2 and against the tapered plug [3 to urge the plug 13 into the pocket on the adjacent side of the hub structure ii. for firmly wedging the same in place. The plug l3 has a gooseneck shaped arm ii, the upper end of which is secured between a pair'of ears 18 by thescrew 11 passing through the ends of the clamp band i8. This clamp band surrounds the lower portion of the barrel IS in which therod 20 is slidable. The upper end of the barrel [9 is longitudinally slotted as at 2! and a clamp band 22.

surrounds this portion and is provided with the set screw 23 which can be operated to tighten the band in place and contract this portion of the barrel I9 to hold the rod 20 in adjusted position with respect to the said barrel.

The upper end of the rod 20 is provided with the yoke 24 through which the headed bolt 25 extends. This bolt extends through the adjacent end of the brace arms 2626, which originally extend from the cross member 21 of the main frame and also through the adjacent end of the arms 28-28 between the outer ends of which the pulley 29 is mounted. Furthermore, the headed pin 25 passes through the pulley 30 which is situated between the outer ends of the arms 26-26 and the knurled nut 3| is provided on this nut for tightening these bars together inproper adjusted position.

The cross member 21 is provided with openings 'in the ends thereof for receiving the upright members 32 -32 of the main frame, these upright members rising from the said hub-like structure ii. The cross member 2'! is provided with set screws 83 at its ends. each notched for receiving the corresponding upright members 32 so that.

when the set screws 33 are moved in one direction or the other, the ends of the notched por- .tions will bind against the uprights 32 and. firmly hold the cross member 21 in the desired position.

Pin members 34-36 are slidable in the upper end portion of the upright members 32-32 and each is provided with a laterally disposed tapered head 36 for engagement into an internally tae pered cup member 36. The cup member is provided with an opening through which the threaded shank Sl'ofthe head 35 passes and a-knurled wardly against the cup 38 to bind the cup on the head 35. Extending from each of the cup-shaped members -38 is an arm 29 while bridging the pins I I4 is the cross bar 40. An arm ll having one nut 38 .on this threaded shank 31 can peied in-.

end bifurcated to receive the cross bar 40 is provided at this point with a set screw 42 to prevent displacement of the arm, while the opposite end is provided with a yoke in which the pulley 43 is mounted.

The arms 39 at their remaining ends are provided with internally tapered cup members 44 for receiving the tapered head members 45 of additional arm members 46. Each of these head members 451s provided with a threaded shank 41 dis 1 posed through an opening in the corresponding cup-shaped member 44. Each of these shanks 41 is provided with a knurled nut 48 whereby the cup-shaped member 44 can bewedged onto the corresponding head 45.

Between the converging end portions of the arms 46 is disposed the parallel bars 49,49. Furthermore, it can be seen in Figure 1, that risin from the cup-shaped members 44 are additional arms 50' which taken with the arms 46 serve as braces for the said bars 49-49 and be tween these bars 49-49 are mounted the pulleys 5|, 52, 53, 54, and 55.

Reverting back to the hub-like structure II, it can be seen that an anchoring extension or brace generally referred to by numeral 56 is employed and this consists in the provision of a pair of horizontally disposed trunnions 51-51 extending laterally from the'plug-like structure 58 which hasv one end tapered for disposition into the tapered pocket on the front side of the hublike structure ii. A threaded pin 59 extends from the bottom of this particular .pocket and through the plug 58 and is equipped with the knob-like nut 60. By tightening this nut against the plug 58, the plug can be jammed into the hub-like structure ll.

Internally tapered cap-like members 6I-Bl are provided on the outer ends of the trunnions 5'l--5| and set screws 62 are disposed through openings in these caps and into'the' recesses in the trunnions 5'l5'l for binding these internally tapered cap members 6| onto the trunnions 51.

Extending from each of the cap-shaped members Si is a rod 83 engaged into the adjacent end the apparatus when it is being employed.

It can be seen in Figure 3, that the base 5 can I be provided with indentations 5a to accommodate the legs of a bed when the apparatus is to be set closely to the bed.

As shown in Figure 11, in using the Russell splint for leg fractures, the foot is taped as at 89 and a cable I extends from this and over the pulley to support the-weight 10. A stirrup II is provided with the knee portion of the leg and from this extends the cable 12 which passes over the pulley 52 and over the pulley 43 and then over a pulley I3 attached to the foot, and then outwardly over the pulley 30, where it extends downwardly for supporting the weight 14. In this connection the super assembly of the apparatus can be adjusted to any desired elevated or descended position and suitable adjustment can be made to accommodate the particular size of person and his posture. I

In the case of an arm fracture as shown in Figure 12, the splint has the cable I5 attached thereto and this extends outwardly and over the pulley 30 and downwardly to the weight 19. The hand is held elevated and provided with the spreader 71 from which extends the cable 18 to pass over the pulley 54 and then downwardly over the pulleys 43 and 30 to the weight 19.

In the case of neck fractures, the chin and occiput straps BHI are applied to the head and from this extends the cable 82 to pass over the pulley 3i) and downwardly to the weight 83.

The pulleys and adjustments can be used in various other positions and adaptations to take care of various other conditions for treatment.

While the foregoing specification sets forth the T invention in specific terms, it is to be understood that numerous changes in the shape, size, and

materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
