To aZZ 'wwm t may concern:

Beit known that l, GEORGE W. HAWLEY, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful lmprovementsiu Foot-Supp orts, of which the following is a specificaa tlon.

'lhis invention relates to a foot support to be used in connection with fracture and orthopedic tables, and its novelty consists in the construction and adaptation of the parts as will be more fully' hereinafter described.

lt often becomes necessary while operating upon a patient on a Afracture .and orf thopedic table to move the leg and foot of the patient without changing the relative position of any of the bones of the leg and foot but itV has been impossible tp do this with mechanical certainty heretofore.

My invention meets that demand and enables the operator to change 'the position Ot the leg and'foot of the patient with 'such mechanical nicety that the relative positions of the bones of the `foot and leg are not affected in theslightest degree.

Also, any desired flexion can be accomplished and any desired traction exerted and the limb immobilized in plaster in the position desired.

1n the drawings, Figure 1 is a miniature perspective of a fracture and orthopedic table showing its use by means of the patient in dottedoutline thereon; Fig. 2 is an enlarged perspective of the foot support in use showing certain operative parts in section; Fig. 3 is an end view of the foot support showing one of the possible changes of position, in dotted outline.

lin the drawings 4 is a. fracture and orthopedic table having two traction bars 5 on each of which is slidably mounted b means winged lock nut 14 threaded to engage theI bar 10 holds a foot-piece 15 with a washer 16 between ina xed position on the opposite end against a head 17 of the bar 10, and bears against a shoulder 2 3 of the telescope rod 8. has a downwardly turned and plate member 19 lwhich has an upturned edge 27. Binding posts 24 are made integral with rod 8..

,This device is adapted to beused in connection with 'an orthopedic table Patent No. 1,126,460, as well as with others, and reference to that is made for a complete description ofthe use of the table.

In use kthe foot of the patient (2() in Fig. 2) to be treated is secured in a xed position by placing the ball of the foot against the plate 19 with the Outside of the foot against the upturned edge 28, an anklet 21 eing secured to the foot and straps 22 secured to the anklet 21 at one end and to binding posts 211 at the other end.

The telescope rod 8 can be raised or lowered manually to the desired height and secured in position by the set screw 25 en-l gaging either of the internally threaded housings 26. By turning the handle 13 of the nut 12 to the left, the threaded bar 10 will'be pushed toward the foot of the patient and contrariwise by theturning to the right. the bone to be treated is obtained. The footpiece 15 can be turned to the desired angle by lirst turning the nut 12 to the left so as to l. move the threaded bar 10 toward the foot 20 of my invention.

I claim:

1 A foot support comprising a sub-frame al foot piece carried by the sub-frame, said sub-frame being wholly supported on an orthopedic or fracture table, and being longitudinally adjustable with respect to the table, said foot piece being adjustable vertically, transversely and axially relative to the sub-frame.

2. A foot support comprising a sub-frame and a foot piece carried by the sub-frame, said sub-frame being wholly supported on ln this way the desired traction on arrangement and disposition of parts may be made without inan orthopedic or fracture table, and being longitudinally adjustable with respect to the table, said foot piece beingA vertically adjustable and axially pivoted on the subframe.

3. A foot support comprising a sub-frame and afoot piece, said foot piece being ad-` justably carried by the sub-frame, said sub-y frame being wholly supported on an orthopedic or fracture table, and being longitudinally adjustable with respect to the table, the foot piece having perpendicular and axial a justment with respect to the subfraine Vand the sub-frame being revolvable on the table.

4. A foot support adapted to be used in connection with an orthopedic and fracture table the sub-frame of which is mounted for longitudinal movement on said table, a T telescope rod slidably adjustable in a tube of said sub-frame, in combination with a foot-piece revolvable in its own plane and adapted to be moved longitudinally with respect to said table.

5. A foot support comprising a sub-frame adapted to be adjustably clamped to an orthopedic and fracture table, a telescoping member adjustably mounted therein, a

I threaded bar adapted to be moved longitudinally to the table mounted in the head of the telescoping member and a foot-piece adjustably mounted on said threaded bar so that it can be secured at any angle desired in itsown plane.

6. A foot support mounted by adjustable clamps having a T telescope rod slidably,

adjustable in a tube of a sub-frame, a footpiece revolvable in its own plane and adapted to be moved longitudinally of a patients leg, in combination with a fracture and orthopedic table having pivoted traction bars on which said sub-frame is adjustably mounted.

7 A foot support comprising a sub-frame adapted to be adjustably mounted by clamps, a telescoping member mounted therein so as to be vertically adjustable, a threaded bar adapted to be moved longitudinally of a. patients leg mounted in the head of the telescoping member, and a foot-piece adjustably mounted on said threadedihr so that it can be secured at any angle desired in its own plane, in combination with aV frac ing an upturned edge revolvable in its own l plane and adaptedto be moved longitudinally with respect to said table. A

9. A foot support comprising a sub-frame adapted to be adjustably clamped to an orthopedic and fracture table, a telescoping member adjustably mounted therein, a threaded bar adaptedl to be moved longitudi'nally to the table mounted in the head of fthe telescoping member and a foot-piece having an upturned edge adj ustably mounted on said threaded bar so that it can be secured at any angle desired in its own plane.

10. A foot support having a foot piece with an-upturned edge mounted by adjustable clamps having a T telescope rod slidably adjustable in a tube of a sub-frame, a foot-piece revolvable in its own plane and adapted to be 'moved longitudinally of a patients leg, in combination with a fracture and orthopedic table having pivoted traction bars on which said sub-frame is adjustably mounted.

11. Av foot support having a foot piece with an upturned edge comprising a subframe adapted to be adjustably mounted by clamps, a telescoping member mounted therein so as to be vertically adjustable, a threaded bar adapted to be moved longitu'dinally of a patients leg. mounted in the head of the telescopng member, and a footpiece adjustably mounted on said threaded bar so that it can be secured at any angle desiredl in its own plane, in combination with a fracture and orthopedic table having pivoted traction bars on which said subframe is adjustably mounted.

In testimony whereof I aix my signature in presence of two witnesses. GEORGE W. HAWLEY.
