SHOE JACK Filed May 5, 1,932

fllSalcaz'an Patented Aug. 15, 1933 UNITED STATES PATENT OFFICE 7 Claims.

The invention relates to jacks employed in making or repairing shoes and embodies improvements enabling a cobbler to make, resole or repair shoes with greater facility, speed and efficiency than has heretofore been possible with the jacks in common use.

Prior types of jacks have comprised a rigid upright post mounting the shoe form in inverted position. It is a requirement of a shoe jack that it be sufliciently rigid to withstand the hammer blows imparted to the shoe on the form, but with the old type of shoe jack, it becomes awkward to work on the edge of the sole or on certain other parts of the shoe because the shoe form is always rigidly maintained in upright position.

and unsatisfactory when the shoe is rigidly maintained in a vertically upright inverted position,

so that the cobbler finds it expedient to remove the shoe from the jack and hold it manually several times during the fabricating or repairing procedure. Consequently, considerable time is lost, and moreover, it is extremely difficult while holding the shoe in this manner to perform work of the highest character.

Accordingly, it is an object of the present invention to provide a shoe jack, which will enable the satisfactory performance of substantially all of the necessary repairing operations upon the shoe without removing it from the shoe jack.

Another object is to provide a shoe jack which will solidly and rigidly mount the shoe in position for hammering upon the sole, and at the same time permit swinging movement of the upper portion of the jack to an inclined position so as to render certain parts of the shoe more accessible.

inexpensive construction which is commercially practicable.

These and other objects are attained by the improvements comprising the present invention, which may be stated in general terms as including a base, an upright supporting post rotatably mounted in the base, means for detachably securing said post in a plurality of axial positions in the base, a shoe form mounting member pivotally mounted upon the upper end of the supporting post for swinging movement relative thereto, means for selectively maintaining said mounting member in upright or inclined position, and means for releasably securing a shoe form in a plurality of axial positions in said mounting member.

In the drawing forming part hereof Figure 1 is an elevational view of the improved jack, showing the base partially in section;

Fig. 2 is a fragmentary View similar to Fig. 1, showing the mounting member in an inclined position, and a part of the supporting post being broken away;

Fig. 3 is a plan sectional view taken on line 3-3, Fig. 1;

vFig. 4 is a top plan view of the jack, showing various axial positions of the shoe form; and

Fig. 5 is a fragmentary sectional view as on line 5-5, Fig. 4.

Similar numerals refer throughout the several views.

The improved shoe jack preferably includes a base 10, having a depending flange 11 for resting upon the floor or other support, and an upstanding tubular flange portion 12; and the base 10 is preferably provided with holes 13 for securing the same to the floor.

A supporting post 14 is rotatably mounted in the base 10, and may be provided at its lower end with a cylindrical portion 15, which is closely swivelled in the flange portion 12 for maintaining the post 14 in a vertically upright position. The portion 15 is preferably provided with an angular flange 16 normally spaced below the central portion of the base 10 for limiting upward 1 movement of the supporting post 14.

The upper edge of the flange portion 12 is preferably provided with a plurality of circumferentially spaced notches 1'7, and a pin 18 extends through the post 14 for engaging in dia- 1 metrically opposite notches 1'7 for detachably securing the post in a plurality of axial positions in the base. r

The upper end of the supporting post 14 is preferably tubular, and is provided with a pair 1 to similar parts of diametrically opposite upwardly extending ears 19, the upper edge 20 of each ear being preferably flat. Between the ears 19 the upper edge of the post curves downwardly to form diametrically opposite stop shoulders 21 for a purpose to be hereinafter described.

A shoe form mounting member 22 is prefer ably provided with a rounded lower end 23 fitting closely within the tubular upper end of the post 14, and the member 22 maybe provided adjacent its lower end with a circumferential recessed portion 2a forming the peripheral shoulder 25. The mounting member 22 preferably tapers inwardly from the shoulder 25 to its upper end.

Means for pivotally mounting. the mounting member 22 in the post 14 for swinging movement relative thereto in opposite directions, may include a pin 26 journaled in a slot 27 formed in the pin.26. is at the top of slot 27.. Since the rounded end 2310f. member 22 fits closely within therupper end of post 1.4, the mounting member 22 will' be-rigidly maintained inupright position by; the engagement ofedge portionsxZQ with shoulder portions 28.

By raising the mounting member'22 to the position shownin .dot-dashalines in 2, with the pin; 26 at the-bottom of slot. 27, the member 22 may be swung about the pin: 26 as a pivot, to the right as shown in Fig. 2, or to the left untilthe recessed. portion 24: is engaged by one of the stopshoulders- 21" for maintaining the mounting member in inclined position.

The upper end of mounting member 22: is preferably tubular, as indicated at 29; and the shoe form 30 is preferably provided with a substantially cylindrical portion 31 adapted .to fit within the tubular portion; 29. The cylindrical portion. 31 may be provided with a peripheral groove 32, and preferably has ratchet teeth formed on its lower end as shownat. 33. w

Ratchet pawls 34 areslidably inserted through suitable. aperturesin the'tubular portion 29' of member 22 for engaging the ratchet teeth 33 at diametrically opposite portions.

Means for releasably securingthe shoe form 30 in a plurality of axial positions in the memher 22 may include a curvedsubstantially semicylindric spring member 35, adapted to snap fit aroundthe upper end of the member 22. The spring member 35 is preferably provided with an, upwardly extending ear 36, to which is se- The spring: member 35' includes curved arms 38 extendinginopposite directions from the ear 36; and: the arms 33 are adapted to fit around member22andover pawls 34 for resiliently holding said. pawls inwardly against the ratchet teeth 33.- The ratchet teeth 33 are preferably slightly. taperedasshown in Fig. 5, to facilitate insertion into mesh with the pawls 34.

It willzbe seen that shoe forms havingdifferent 5 foot sizes or shapes may be readily inserted into or removed from the tubular portion 29 of the mounting member because of the yielding resistance offered by the spring pressed stud 37. The shoe form is releasably secured in any of a plurality of axial positions in the mounting mem-- ber, such as shown in Fig. 4, by means of the pawls 3e and ratchet teeth 33. The spring 35 presses the pawls against the ratchet teeth to provide sufficient resistance to twisting or rotary movement of the form for all practical purposes, but permits rotary movement of the form from one position to another by a quick manual twist upon the form.

In the operation of the improved jack, when a shoe is mounted upon the form with the mounting member 22 in upright position, as shown in Fig. 1, the operator may pound at will upon the shoe and the mounting member will be rigidly maintained in its upright position in the manner previously described. When it is desired to render some portion of the/shoe more easily accessible without. removing it from. the form, the mounting member. may be quickly and easily swung to the right or left toassume an inclined position, as previously described in connection with Fig. 2. In this inclined. position, the form may be rotated to a plurality of axial. positions in the mounting member, and thewhole jackmay be. axially rotated in the. base to a plurality of. positions by raising the post 14.and engaging the pin.18' in a diiierent pair of 'notches 1'7.

The result of this combination. of adjustments is to make it'practicable for. the cobbler to rapidly and efiiciently perform substantially, all of the. required. shoe making and repairing operationsupon a shoe without removing it from theform. v

The simple and compact construction of the improved jack makes it extremely inexpensive to manufacture, and the above described advantages of operation result in a substantial saving of time and effort, without detracting from the high character of the work performed.
