M l. l A 'preferred construction has been illustrated in the accompanyingdrawings and will be ratherV specifically` described, with the understanding however, `that within, the scope of the invention as claimed, variations may be made. n v

.An expansible leg form L is shownhaving v'a forwardly projecting instep form yI and provided also with a heel form H, both forms I and H being` detachable from the leg form L, in order that instep andheel forms of different dimensions may be substituted the tree or TheJ ieg form L isdrvided info from and rear sections F and R respectively, and the.

i upperand lower end facesof said sections,

are formed with parallel undercut grooves l2.v Plates l3lie against the aforesaid end faces or' the sections F and R and are provided with dove-.tail ribs 14 which are slidably received in the grooves 12, said plates 13 being formed with central` openings l5. Vertical screws 16 passrotatably through the lopenings andare rotatably mounted in bearing blocks 17 which are shdably seated in recesses 13 formed in the adjacent sides of the torni sections F and R. Also formed kin these sides ci' thesections F and R, are longitudinai wedge-ways 19 in which wedges 20 are slidabiy received, the screws 16 being threaded through said wedges respectively.,

By operating the upper screw, the upper ends or the form sections F and R may be spread to any desired extent, independently of the ower'ends of said sections. Similarly, by operating the lower screw, the lower ends of said sections may be spread without similarly i moving the upper ends of the sections.'

Filler strips-21 are interposed between the seetions'F and R of the leg form and are provided in their ends with vundercut notches 221slidably receiving the ribs 14. Any desired numberof' thesev filler strips may be employed, or forunusually small boots, all :of them* may `be removed.

The instep form I is dove-tailed to the front leg section F as shown at 22a, being detachably secured by screw 23 (Fig. 3 .v The crest ofthis instep form I, and the' ront of thelegsection F are formed with registering Ylongitudinal grooves 24 Vand 25, in which a flat metal strip 26 is snugly seated, the upper portion of said strip 26 being securedfto the leg section F by a screw 27, while the lower portion of said strip is secured by another screw 28 to the instep form I. By removing the

screws

28 and 23, the instep form I may beV downwardly slid from the leg form, whereupon another instep form of desired proportions may be substituted. .V

Thestrip 26 is provided with a plurality of spurs .29 spaced apart longitudinally thereof and adaptedfor passage through the "overlapped edges "EIO of the boot-forming leather or other material 31.` These spurs Vthus not only anchor the overlapped ed es ofthe material, but form the same with per end of the leg being formed A material 3l. Any desired number of the liller strips 2l may be-einployed, or they may all vbe omitted as desired, and instep and heel openings to later receive eyelets or the like.

To prevent accidental pulling of the edges 230 from the spurs 29, a clamping strip 321s employed, said clamping strip havmg its lower end hinged at 33 to a plate 34, the latter being detachably secured by a screw or the like tothe lower side of the instep form I. Strip 32 extends along the crest of the form I and vertically in front of the leg section l?, and is provided with openings 36 which receive the projecting ends of the spurs 29. The upper end of the strip 32 is formed with a vertical slot 37 through which the flat head 38 of a clamping screw 39 may pass, said screw being threaded through the upper end of the strip 26. By turning the screw 39 retrogradely to loosen it and then disposing its head 38 vertically, the strip 32may be forwardly swung .to released position, the slot 37 then clearing said head 3S.

When detaching the instep form I for substitutlonof another, the plate 34 is detached from said instep form and is attached to the form to be substituted, detachment and reattachnient of said plate 34 being effected by means of the screw or the like 35.

The heel forni H preferably embodies a block 40 secured wit-hin the bight portion of a U-sliaped metal plate 4l, the ends of said plate constituting forwardly projecting ywings 42. The upper end of the block 40 abuts the lower end of the leg section R and is provided with an upstanding stud 43, said lower end of section R being formed with a downwardly opening socket 44 which removably receives said stud. The lower end .of blocs 40 projects below the plate 4l and is provided with ears 45 to which the lower end of a rear clamping strip 46, is hinged at 47.

This strip 4G extends vertically at the rear ofthe section R and isprovided with releasable clamping means 47 at its upper end, similar to the clamping means for the front strip 32.

The heel forni II may be readily detached from the leg section. R and replaced with a heel form of other required dimensions, and when so doing, the clamping strip 46 is detached from the one heel forni and attached to the substitute form.

The spurs 29 and the front and

rear clamping strips

32 and 46, serve to hold the leather or the like 3l against the form, so that upon operation of the screws 16 and consequent spreading of the sections F and R, said material may be stretched to the required eX- l tent. If desired, a spring-contacted band 48 may be employed to assist in holdinv the upfrom the forms I and IFI of desired dimensions and proportions, may be used. Hence, bootlegs of desired sizes and shapes and having instep and heel portions of proper dimensions, may be readily formed with the improved tree, and due to the spurs 29, the front edges of the leg and instep portions will be provided with openings for eyelets or the like.

The rear clamping strip 46 is preferably provided with a measuring scale as seen in F ig. 5. The part 49 shown at the lower end of this strip is merely a spring which assists in outwardly swinging the strip 46 about the hinge 47.

Y Attention is again invited to the fact that variations may be made within the scope of the invention as claimed.
