SHOE-STRETCHIN G LAST.

Ap'pncation sied .my 25, 1927. semi No. `208,155.

rlhis invention relates to a shoe stretching last, and has for its principal object, the provision of means in a single last for individually or simultaneously stretching the shoe length, the width ofthe counter, :the height ofthe toe box and the vamp and shank of the shoe.

Another `object is to v shape of which` can be changed to accommodate various .styles of shoes. l Other obje-cts and advantages reside in the detail construction of the invention, which is designed for economy, elliciency and simplicity. hese will become more apparll ent fromr the following description.

YIn the following detailed. description of the invention, reference is had to the accompanyin `drawing which forms a part hereof. Li e numerals refer to like parts 80 in all views of the drawing and throughout Vthe descri tion.

In the rawings: 'K Fig. 1 is a side elevation of my improved last. `1 2 'is a yplan view thereof.

Fig, 3 is a horizontal section through the last, taken on the line 3 3, Fig. 1.

Fig. Llis a. vertical section, taken on the .line lr-4, Fig. 2. Inthis section, the length Yof the last has beenincreased by means of the lengthadjustment and the toeA has been raised to the position employed for stretchingthe capand toebox of a shoe. n

Figs. 5 and 6 are horizontals'ections simllar to Fig. 3 illustrating the mechanism in various positions to bel later described.r

My improved last isshaped in its entirety to conform to the last or' interior surface of' an avera e shoe, it being intended to have 34o ai pair o lasts typical for ladies shoes, a

second pair of` lasts for mens, and athird pairfor childrens shoes. VIn thedrawings theladies` last is illustrated.

My improved last comprises. 'a body 10,A

separated therefrom by a spacerf16., VOnV each side of the heel member 15, adjustable right and left counter stretchers 17 and 18, respectively, are carried. f

provide a last, are.

rlhe toe member 14jis secured to "a leafA spring 19, which in` turn is secured to the;

ledge 13 so as to provide a spring hingeuatv the point of the toe member. `The toe meinber is preferably attached to the spring 19 by Vmeans ofscrews, as illustrated, so that members to suit various styles of toer Vshapes may be used interchangeably. rfhe rear portionV of the toe member may be raised by means of an adjusting screw 20l `which acts to force a ball 21,7 which acts as a wedge,faga inst an inclined surface 43 under the rear portion of the` toe member.' VMotion is imparted to the ball 21fthrough a .second ball 22 anda plunger 23 which are actuated by the adjusting screw 20. ,'By'this con# struction rotation ofthe adjusting screw in Y onedirection will raise the rear portion kof j the toe member 111'; and cause ity to stretch the cap and .toe box of the shoe;- Rotation vof the screw in the opposite direction allows the leaf springA 19 to force the balls 21 and 22and the plunger 23 into the body 10.

Each of the vamp stretchingmembers 11 and 12 is pivoted adjacent its one extremity at 24; to a hinge bar25. The hinge bars 25 in turn are pivoted adjacent the other eX.-

4tremities of the vamp members at `26. A

spring 27 connects the vamp stretching meni- .bers through-the body 10 and acts to con stantly draw vthem toward each other, Should it be desired tostretch the forwardl portion of the vamp adjacent the toe b'oX, an adjusting screw 28 is rotated. The screw 28 is provided with a pointedV extremity which acts to.. forceY a pair of balls 29 apart. The balls 29' act against the hinge members 25 to swing them about their pivots 216, asshown I i in Fig. 6, thus causing the forward extremities of thef vamp members l1 and 12 to move outwardly and stretch the shoe. HRotation of the adjusting screw 23 inthe opposite direction allows the spring 27 to return Athe hinge members to their former position.V

y Should it be desired to stretch the rear portion of the vamp, a third adjusting screw 30 having a similar poined extremity kis rotated so as to separate a pair of ballsf31 carried in the body 10. This forces plungers 32 against the rearward extremities 'of lthe vamp stretching members 11 and 12, as

lli() shownlin Fig. 5, thus stretching the shoe atl the rear of the vamp.

Should it be desired toy ,stretchv theentire length of the vamp, both of the adjusting screws 28 and 30 may be threaded inwardly so as to move the stretching members ll and l2 outwardly in substantially parallel relation, thus combining the actions of Figs. 5 and G.

Should it be desired to stretch the length [of the shoe, a pinion shaft 33 is rotated. The shaft 33 carries a miter pinion 3a which meshes with a similar pinion 35 carried on the mid-portion of a right and left hand threaded screw 36. "One extremity of the screw 36 is threaded into the body l0, the other extremity is threaded with an opposite hand thread into the heel member li The shaft "Q rides vin the separator 16 ou which Vsurrounds the screw 36 and acts to maintain the miter pinions in mesh. The separator moves with the movement of the screw and always maintains a mid-position between the body l() and the heel member 15. lt is prevented from rotating with the screw by a tongue 3? which tits within a vertical groove in the body member. The heel member l5 is prevented lrom rotating on the screw by means of a pin 38Vwhich rides in openings Vin the separatorI and heel member.V

It can be readily seen that rotation 1oit the shaft 33 will cause the heel member l5 to move away romrthe body member l() as shown in Figs. l'and 5, so as to increase the length oit the last and stretch the length of the surrounding shoe. Y i Should it be desired to stretch the width of the counter, a fourth adjusting screw 39 having a pointed extremity is rotated so as to cause the pointed extremity to separate a pair of balls 40 carried in the heel member l5. These balls act against the counter stretching members 17 and 18 so as to separate them from the heel member, as shown vin Fig. (5.

When the adjusting screw 39 is released the counter members 1T and 18 are returned to their former position-s by a leaf spring 4l,

to the extremities of which they are secured at 42. The mid-portion of the spring 4l is secured to the i'orward face of the heel member 15.

The body member is preferably, but not necessarily, made of metal, and may be slreletonized to save weight if desired. The movable stretching members may also be of metal but could be formed of hard wood or similar light weight material. 1

lVhile a specific form of the improvement has'been described and'illustrated herein, it is desired `to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
