. a Shoemaker works on a shoe held by such a last, it is usually necessary vfor him to either move around the stationary last or else to twist his body into uncomfortable and cramped positions as he works on different parts of the shoe.

The principal object ofthe present .in-4 vention is to provide a novel standard for ay shoemalers last, which is so constructed and arranged as to enable the angular adjustment of the shoe last with respect to the .vertical 2() Another object of the presentA invention lies `v in the provision of a novel last supporting standard having an angularly adjustable last supporting block, together with easily operable meansv for holding the block in any desired angularly adjusted position, said adjustable means also providing for the free swiveling of the supporting block, when desired.

Still another object of the present inven-VV tion is to provide a novel standard fora shoe- 35 makers last which is of simple, sturdy con- -time more particularly enumerated,will be clearly understood from the following detailed description of the same.

The invention is clearlyillustrated in the accompanying drawing, in which:

Fig. l is a view in elevation of thenovel. last supporting standard of the present invention showing a last mounted thereon.

Fig. 2 is a view similar to Fig. 1 with parts brokenl away to illustrate details of construe,` tion, the-last and its block being illustrated as held in xed position.

' F 3 is aview similarv to Fig. 2 but with the lastl audits `block illustrated as freelyI turnable. Fig. 4 is an enlarged fragmentary sectional view taken along line 4-.4 of Fig. 2; and Fig. 15 is la sectional view taken along line 5-5 of Fig. 3 but Jshowing the operating pedal turned to an angle to effect the lockingA of the operating mechanism in released position. I

s Similar `characters of reference are em-.

ployed in all of the above described viewsvto indicate corresponding parts. Y

Referring now to saiddrawing, the I 'eference numeral l designates la shoe last which` is'l illustrated as supported by the rnovel standard of the present invention. This standard comprises a circular base 2 which may be made of cast iron or other suitable` material andispreferably fixed to the floor. A hollow cylindrical column or tube 3 has its lower end portion securedv to the base 2 and extends .vertically .upwardly 'from this,

base. The top of the column 3 'is left open for receiving a.l dependingr cylindrical le-x tension` or boss 4 formed on a shoe last supp-5 porting block 5. l y l Last supporting block 5Y is illustrated as of cylindrical shape, the samebeing of larger diameter than theV column 3, whereby this block is adaptedfto rest upon 'the column with` itsV depending boss l projecting downwardly through thev open upper end of this column and intothe interior thereof. The upper surface ofthe-block 5 is provided with a non-circular recess ffor conformably receiving the shank 6 of the shoe last l. With` the shank 6 of the shoe last setinto the recess l `ture9 p'ro-videdin the column 3 so that this ball will engage in any one of the pockets7 to thereby lock the boss 4 against turning movement. A shoe member 11, illustrated as of approximately semiscylindrical shape in cross section, is employed for moving the ball 8 through aperture 9 and into engagement with any one of the pockets 7. This shoe member 11 has a tapered ball receiving recess 12 therein, as especially shown in Figs. 2 and 3, which recess is open toward`the aperture 9.

The depth of the'ba-ll receiving recess or` slot 12 increases from nothing at the lower end of this recess to a maximum at the upper end thereof. VVh-en the shoe member 11 is positioned so that the lower end of recess 12 is opposite the ball 8, the latter is held in engagement with onel of the pockets 7, thereby locking boss 4 and hence the last 1 against turning; but when this shoe member is positioned so that the upper end of recess 12 is opposite the ball 8, the latter is free to enter the `deep portion of recess 12, thereby disengaging the boss 4 and permitting turning movement of block 5 and last 1.

VIn order to move the recess 12 up and down with respect to the ball 8 and aperture 9, the shoe member 11V is made vertically adjustable and to thisend is mountedl within a slide bearing provided in bracket 13 that has the form of a strap encircling the column 3. A set screw 14 serves to lock the bracket 13 in fixed posit-ion upon the column 3. The lower portion of the shoe member 11 is somewhat enlarged as indicated at 15, which en.- largement'by engaging the under surface of bracket 13 is adapted to limit the lupward movement of the shoe member. ,l y

A coil compression spring 16 surrounds a vertical rod 17 and bears at its lower end against a bracket 18 and at its upper end against the funde-r surface of the vshoe member 11, thereby urging this shoe member up`- wardlyso thatthe lower and shallow end of recess 12 will engage the ball 8, resulting in the locking :of the shoe last against turning movement, as especially shown in 2. The bracket `18 is similar in form to the bracket 13 and is fixed upon thecolumn or tube 3 by a set screw 14. The vertical rod 17 has its upper end portion threaded into the shoe member 11 and extends downwardly through conforming apertures provided in thevbra'cl'ret 18 and in a bracket 20 which is similar to bracket 18. Bracket 20. is also secured in fixed position in the column 3 by a set screw 14. The lower end yofthe rod 17 terminates near the base 2 and this rod has at pedal 21 fixed upon the lower end portion releasing the boss 4 and enabling 'the turning of .shoe last 1 to any angular position desired. A transverse pin 22 is lixed to ro-d 17 and is positioned within a vertical slot 19, provided in the bracket 20, when the ball 8 engages in one of the pockets 7 (see Fig. 2). As the pedal 21 is depressed, the pin 22 moves downwardly within the slot 19. When the pedal 21 is fully depressed, the pin 22 has moved below bracket 20, an-d by then giving the Vpedal a part turn with the foot, the pin` 22 may be caused to engage the under surface ofthe bracket, as especially -illustratedinlFig 5, thereby holding rod 17 in its fully depressed position, and freeing the ball 8 from engagement with pockets 7.

In use, assuming that the shoe last 1 is in the position illustrated in Fig. 2, and that the shoemaker is desirous of turning this last around into the position shown in Fig. 3'. To accomplish this result, all that he need 1 v do is to press his foot down upon the pedal 21, thereby depressing this'pedal into the position shown in Fig. 3. With .the pedal 21 thus depressed, the deep portion of groove 12 lies opposite ball 8, thereby freeing this ,4-

ball from pockets7 and permitting the turning of the shoe last 1 into the desired position.

Should the shoemaker now desire to lock the shoe last 1 in fixed position, all he need do is to release hisv foot from pedal 21.there by Venabling spring 16 to raise this pedal and shoernember 11 so that the shallow portion of recess or groove 12 moves oppositeball 8, thereby pushing this ball inwardly and into engagement with ay pocket 7 registering with the aperture 9. On the other hand,

should the shoemaker desire to havey the shoe last 1 freely turnable, all he need dois to give the depressed lpedal 21 a portion of a turn, sothat the pin 22 engages the under side of bracket A20, as illustrated in Fig. 5, whereupon the rod 17 is held in its depressed position and the ball 8 is maintained inthe deep portion offrecess 12.

Owing to the use of the plurality of pock-Y ets 7 e extending completely around the boss Y 4, the last 1 may be locked in use in substantially any desired angular position with respect to the supporting standard. It will of the foot. the shoemaker is enabled to either free the shoe last so that the same may be turned to any convenient position or he may lock the last in any .such position at will. :The

simple rugged nature of the novel standard,

11.5. thus be noted that by simple manipulationsr the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
