. theiultiinate purpose-being to give the shoe a. snug. fit about the waistiof the foot while giving the larger ballportion of the foot.

ampleopportunity to s read in the shoe while supporting the Weight of the wearer.

' In-the, drawingswe have illustrated various forms-of embodying the principle of this invention.

Figure 1. is a; side. elevation part1 sectionshowing oneforniof the last. 1g,.23isa lan view of the same-partly iIL'SQCtlOH. igr 3 is adetail view'of the separable section of the: fore part. Fig, 4 is aside elevation. partly in. section or broken. away to show interior parts. of the same artlyins'ection.

The under yinggprinci is of. our invention.

consistsin dividing the orepart of: the last in the direction of its longitudinal axis by a vertical division, the cut-out portion being coinpletely severedfrom the other and having a sliding temporary engagement with the main section of the fore part by which the two arts are held togetherby spring tensionw ion in their normal position for service but are-com 'letely' se aratedby 7 the act of Withdrawing t 6 main, ody of the last from the shoe, thereby leaving the sep-.

arable section to drop' out when the shoe'is inverted.

In the-practice of our invention according to the form shown inthe first three figures of h drawings, the-last block a issevered by S'pocmmfionotLetteislPateut. Application man January ma sci-1am. 470,502.

Fig. 5. isaplan viewrawnted ma arena,

: a longitudinal out as at (1" extending. from thetoe-along. the longitudinal axis of' the lastto its middle; portion, thence laterally 'to' the side ofi thelast back of the balls The of. the last is grooved on its inner longitudi nal faceto-receive as ring metal tongue 6 which is firmly secure at-itsforward end in anysuitable mannerto the-inner. wall of the.

Wardly and outwardly sothat its-: rear endproiect's some distance beyond inside wal or-face of the section as shown in Fig.

The vertical inside face of the main section a is provided with a staple or hook -like device a adapted to receive the springtongueb' to-allowthe same to have a sliding movement therein. The main portionmay wall: ofi the separablc sectionrb is provided fixedin the corresponding portion of the main section at As-the rear portion. of the groove so as to engage the cooperating st'a lea,v it is obvious that when the sep=- ara lesectionis-placed in position to have the rean orfree end of the spring'tongue enterthe staple, the-parts are thenin posi tionto permit the rearward movement, which owingto the-inclination of the spring tonguertends to'pressthe twosections closely together as the separable block assumes its normal position for service. Theguide pins 0/ and a engaging the sockets or recesses in the separable section tend to hold the two parts rigidlyin operative position to resist external pressure when the shoe is being lasted or otherwise worked upon.

- In Figsal and 5 We have shown a somewhat modified. .l'orm of the invention. the main section a ofthe last block and the separable section b are divided as above described but instead of employing 'a single :staple for receiving the spring tongue 6 we {provide two-staplesa and a placed astride awear plate a through both of which the spring tongue is passed. In this case the Int-nit some distance-apart, serves to prevent slot or groove 6 but which is inclined rear;

sectibn-b Whichfills out-this cutaway portion from its proper operative position relative to the main section. In order to avold the spreading: open of the two sections at the toe portion to enable the laterally projecting 5 guide pin of. the main section to passby the I springtongue, we make this guide pin in the form of a yielding plunger a, seated in a pressed plungera adapted to press forward.

normally against the rear face of the sepa- 2o rable'section 'b. When the parts of the last are in lace in the shoe, the external pres-j sure 0 the uppervkeeps this plunger retracted but assoon as the main section isdrawn back to give the two sections a chance to separate, .the lunger acts to. cause this separation. In ig. '1 we showed the heel portion of. the last block joining the main portion withoutv any break or joint. In the orm shown in Fig. 4 however,.the heel portion of the last is hingedly connected to the main body of the fore part. b means of a hinged-joint c, a wedge-shape filledbya wedge-shaped piece 0 having sliding engagement with the rear transverse wall of the fore part and the front transverse face ofthe heel part. v The above described constructions make it possible Waist portion properly adapted 40 the 'foot and an-v enlar ed ball' ample room toallow t spread inside the shoe and is also capableof satisfyin'g extreme requirements for large to support ballmeasure relativeto the waistvmeasurement in cases where a bunion. or swelling is formed on the ball of the foot as often happens. a I

What we claim is i 1.
