SHOE REPAIRING JACK Filed May l, 1931 INVENTOR. JAMES LEEDS 1 FIESI BY ATTORNEY.

Patented Apr. 19, 1932 JAMES LEDDY, OF SAN FRANCISCO, CALIFORNIA SHOE REPAIRING JACK Application filed May 1,

The present invention relates generally to improvements in shoe repairing jacks and more particularly to improvements in shoe repairing jacks of lever actuated character.

The primary object of the present invention is to provide a shoe repairing jack which eliminates the strap generally used bycobblers to hold the shoes on the usual form of shoe jack.

Another object of the invention is to provide a shoe repairing last of the class described which includes mechanism for clamping shoes by the soles thereof and also means for clamping the heels of womens shoes to the last.

Still another object of the invention is to provide a shoe repairing ack which positively clamps the shoe in place upon the last form and holds the same in fixed position while the shoe is being half-soled or the heel of the shoe is being repaired.

Additional to the foregoing objects is that of providing a mechanically operated shoe repairing last which is comparatively simple in construction and operation.

Other objects and advantages of the invention will become apparent with reference to the subjoined specification and the accompanying one sheet of drawings in which Figure 1 is a side elevation illustrating the ack in general and showing a shoe clamped in position upon the last thereof;

Figure 2 is an enlarged side elevation of the operating mechanism of the jack and showing the last in reversed positions;

Figure 3 is an edge view illustrating the jack with the shoe clamp in operative position as in clamping a mans shoe upon the last of the device;

Figure 4 is a vertical sectional detail illustrating the various operating parts of the jack, as indicated by the line 4-4 in Figure 2;

Figure 5 is a perspective detail illustrating a womans shoe held in position upon the last by means of an additional heel clamp carried by the device; 7 v

Figure 6 is a sectional detail illustrating the configuration of the last supporting spindie, as indicated by the line 6-6 in Figure 4; and

1921. Serial No. 534,177.

Figure 7 is a fragmentary detailillustrating the hingeand means for normally urging the shoe clamping lever to inoperative position, as indicated in full lines in Figures 1 and 2-and in dottedlines in igure 3.

Referring more particularly to the drawings in which the preferred form of the invention been illustrated the'numeral 10 generallydesignates the shoe repairing ack, M

The head 13 carries the working parts of the device and consists of the usual removable and reversible last 1.7 fitted upon the upper tapered end 18 of the shank 19 upon which the shoes are placed for half-soling and the like.

As indicated in Figure 1, a shoe 20 is shown clamped upon the last 19 for repair purposes and is indicated as clamped to the last in the following manner V Aclamp lever 21 arranged transversely of the last 17 and pivoted or hinged at the point 22, which hinge is carried by a slidable collar 23, arranged to slide upon the shank 19, carries said clamp lever upwardly and clamps the shoe on the last, by, and through means hereinafter described.

An actuating lever 24-, pivoted at the point 25 to the collar 23 and having an arcuate slot 26 arranged in the segment 27 thereof, which slot 26 engages a pin 28 carried by a fixed collar 29, causes the upward movement of the slidablecollar v23 upon the shank 19.

This upward movement of the slidable collar 23 is'due to the fact that the pivot point 25 is eccentrically arranged relative to the arcuate slot 26 formed in the segment 27, which causes the clamp 21 to be first raised upwardly and then brought downwardly to engage the shoe sole and hold the shoe in a firm clamped position upon the last.

The collar 23 also carries an upright bracket 30, which bracket has pivotally supported at its upper end a heel clamp 31 having a forked end 32 adapted to grip and hold the heels .33 of womens shoes, a fragment of which is shown on the last 17 in Figure 5.

The heel clamp 31 is manually controlled and normally rests in the position shown in Figures 1 and 2 as also does the clamp lever 21, as indicated in Figure 3, a handle 34: being attached to said lever 21 to provide means for the manual swinging of the same from inoperative to operative positions.

A heavy coil spring 35 is mounted upon the shank 19 between the slidable collar 23 and a fixed collar 36, said spring tending to normally urge the actuating lever 24 downwardly to assist the operator in drawing the clamp 21 downwardly upon the shoe sole.

What I claim and desire to secure by Letters Patent of the United States is the following 1. A shoe repairing jack of the class described comprising an operating head including a fixed shank having a last mounted thereon, a slidable collar upon said shank, shoe clamping levers carried by said collar and eccentric means associated with the collar and adapted to actuate said clamping levers.

2. A shoe repairing jack of the class described comprising an operating head e1nbodying a fixed shank having a shoe last associated therewith, a slidable collar mounted upon said shank, shoe clamping levers pivotally carried by the collar, and a segment eccentrically mounted upon the collar and adapted to actuate said clamps.

3. A shoe repairing jack of the class described as claimed in claim 2 and including spring means cooperating with the slidable collar to urge the clamps to shoe clamping positions.

l. A shoe repairing jack of the class described comprising, in combination, an operating head embodyin a fixed shank having a shoe last associated therewith, a slidable collar mounted upon said shank, shoe clamping levers pivotally mounted upon the collar, and segments eccentrically mounted relative to the collar and adapted to raise the same and carry the clamping levers upwardly and then downwardly to clamp the shoe fixedly upon the last.

In testimony whereof I hereunto ailix my signature.
