lle vit known that I, FREDERICK JouN h'liamsnr, Sr., a citizen of the United Statics, residing at Dayton, in -.tbe county of Mont rolncry `and State of Ohio, have in- )sible-Last lescription, in connection with the accompanying draw- `ingsuis a specification, like letters on the My invention is a. collapsible last lock, capable of automatically locking the instep block of a last in expanded or dis-tended position, one form of my invention also pro-.

riding means for automatically holding thel instep block of the last in collapsed position while l)erlflittingf thc heel part to swing in- One of the most diilicult problems to sol vc in this art is theproper locking of hinged lasts without introducing colnpllcatedgor ex- ,e'nsive accessories. Of course the lock must e located yiadjaccnt the transverse cuts or .openingsof the lust, and these must ot be cut away `to any extent because the train which is brought upon'the last is g 'eatest nt this middle region and hence all tle 4mate l must remain lor stren th. According; my present invention inc udes the rovislon of a latcl or bolt, stamped out o' the boundaries' of the latterin one and the same plape therewith, ,being automatically pro- Jeqted behind `the collapsin pin or rivet when the last is in expander? position.

Inrther advantages of my mvention and thegconstrnctonal ,details thereofy will be m laplgmrent from the following descripf taken inconnection with t e accomppnying drawings, in which Ihave shown reife out of many embodiments of which vention is capable. n*-hedrawingaFigures 1 and 2 reprepartly broken away, a iw .prmgidedf with vone 4form of my inventhe last in its lengthorexpanded position, and Fig. 2 in its collapaedfposition; 3 and 4 are views of the two, arts ofthe compound hinge connection; Fig. shows a hook lfor unhooking theY last; Figs. und 7 are views similaito Figs. 1 and 2, showing a simpler form of my invention; Fig. 8 is a side view of a modi- Lettersl'atent.

My invention applies more particularly to what are known as the Pym collapsible lasts, sometimes called also Krentler collapsible lasts on account of the various Krentler iniprovernents on the original P m construction. This type of last; as s own in the drawings, comprises a heelpart l and forepart 2, .comprising also a body ortion 3 and un upper or instep part 4. I lave omitted in the drawings to show the various usual last trimmings, and will confine my description to the improvements Whichconstitute my invention.

The last parts are severed as usual, by a longitudinal downwardly curved slot 5, eX- tending forwardly into the fore art to permit the instep block to' rise and all, and the V-shaped gap f between the rear end of the instep block md the forward end vof the heel partfor permitting the latter to be turned on the pivot pin 7 as a center. The heelpart 75 is provided with a vertical kerf 8 and the forcpiu't with an alined vertical kcrf 9, 10,

in which, Ain the last of the drawings, Figs.

1 and 2, plates I1 and 12 are mounted standing in-one and tl e same plane, and in Figs. 6 and7 a single plate 13. The plate 11 is secured at its forward end on the pivot-7 and at its rear end is made rigidly fastby transverse pins or rivets 14, l5, While the forward plate 12, which together with the plate 1.1- constitutes the compound hinge connection between the three parts of the last,

is provided with .a cam-shaped slot or open- 'ing 16, in which Works a transverse pin. 17,

operating on 'the general principle explained 90 for eiiample in the rPym Patent No. 673,889. The slot 1-6' is provided with a lower recess 18 and a semi-circular portion 19, in which VI mount a tongue or bolt 20, held under a normal tendency to rise, by means of a. spring 21, secured in notches as shown plainly in Figs. 1, 2, 4 and 8, in the opposite edges of the adjacent parts, so that the bolt is 4normally heldin the position shown the bolt locking directly against the pin 17, whereby the last is held unyieldingly extend l.- In Fig. 4 the spring is omitted and the latch is down in the recess 18. The recess 1.8 and bolt 20 are length andso located that in whatever postion the parts are, the bolt is engaged at its lied form of hinge.

opposite sidesxand preferably also adjacent in thedrawings Figs. 1, 2, 8, Fig. 1 showing 100 preferably of such a V10:5

\ lar ement for the' in 7, anda shoulder -permit this movement downwardly. `To facilitate by the walls of the adjacent erfs,so that 1t is im ossible for it to drop out or be inadvertent y pushed out or loosened. The bolt turns up lon its socket recess 19 with a hinge-like action, and is always `in proper position, being stamped fromV the slime ieee of metal owhich the hinge is forme its opposite ends,

y Above the boltis an enor extension 22 in the cam slot 16, see 1,'for receiving a pron vor hook 23, Fi for depressing the late or bolt 20 when the arts are in the position shown in Fig. 1, an for the pin 1;1 when the gats arein the position shown Fig. 2. e plate'11hasvan annular r ear 24 concentric with the perforationr opening i plate 12 as a correspondingly 26 tting'snugly on the ear 24 in the same plane therewith, and terminati 27. 4Thehook-sha jend 28 ol the late 12 at the lower si on the 'arc surface' ofV partially embraces, and coperates with the cam slot 16 and in 17 in compelling the instep block A,to c ose down into collapsed osition as shown'in Fig. 2, when the plate 2 has been turned forward about theFpin 'T as a center, 4to the ositionshown in` xg. 2. When in'this osition'the fore'part will remain collapsed and the' ,heelpart can be or down, as shown in full lines and 1n otted lines; actively. This facilitates the entrance o y shoe without disturbinlgethe lining, and permits the heelpart to lowered while the foreart'still remains colla ed. l en the heelpart has n lowered, the forepart is distended or lexpanded byfturning the plate 12 backwardly and ownwardly upon the pin 7 as a center, and to to be readily accom plis'hed I have provided the late 12 with a shouldered projection 29, w ich provides a notch 80 against which the hook 23 may be pressed, thereby turningh the plate 12 t e speedy final movement of the -plate 12 l'. provide a second notch 31, against which the hook 23 may be pressed when the parte are nearly in the position shown in Fig. 1, for completing" the movement. The moment that the plate 12 has been turned into its final rearward position, the latch or bolt 20 is instantly raised by its spring thereby rendering the last perfectly rigid. To give 'great strength to this position I have' rovided a curved foi-ward edge 32 to the pate 11, and a correspondingly curved edge V33 V'to the plate l2, so that said edges 32, 33, meet throughout their length when the last is lengthened and expanded, said lcurves interlocking and preventing any tendand possibility of Vshifting' movement. Figs. 6*8 asimpler form of connection and the` shaped recess in astop e'of the recess 26 sides the ear 24, which it ltlie last'within a fintoV the annular seat 21 into locking position,-

is shown, in which th independent movement of the instep h ook is omitted, they hinge late 13 there shown containin a cam slot the same as the slot 16 of p ate 12, and a bolt or latch 35 the same as the bolt 20 already described, said bolt 35 being 9p- 'erat'ed by the hook 23 inserted in an enlargment 36 of said slot correspondingrto the enlargement 22 already described. he bolt Sofie shown asdield'raised by atlat loafA spring'j? in Figs. 6 and 7, andvbya icoiled spring 38 rin Fi 8. YThe plate 13 has three holes `39, 40, 4 for receiving a pivot pin 7 and tra erse' insyor rivets 14, 15, of the lastfaeo adyl The plate 12 is retersbly grossed with oldngjnotc 42120 enga or rivetewasshown in 2.

In making xn l. im rov collapsible last, the last issaw 'in ,eusualmannerandjis then provided 'with vertical saw lcuts or kerfs y extending inwardly, in alinetnent with each other, perpendicolari tol-the meeting faces of the' adiacentseca t ends, said! saw cut or kort eprresponding accurately width to the thickness' of the plate and con` nections 11 and 12 or' 1.8, as thel case may he. In the 'former case theplate 12 is interiocksd with theplate 11 so that the' recess 2o fits tightly and accurately over the bossor a transverse pin `ear 24, and the curved edge 33 is nested snug against, the edge 32. :The circular 'rear end of the bolt 20 1s then pressed snugly 19 provided v.there or in the plate 12, and the sprinlm is pressed into `its holding notches. e compound connection, as thus assembled, is thenlplaeed in the alined kerfs of tl'lelast and the `pins T, 14, 15 and 1T are inserted and secured, there'- by'complctingl the last. If now it is desir to insert the ast in a lastedshoe, the bolt` a shoulder or? 20v is rst de ressed by the hook 23 and the heelpart is tt en turned up to'the osition shown in F1g.'2, thereby ing the plate 12 forward, and as its cam slot '16 rides over the pin 17 1t automatically coll lapses the forepart, whereupon the last is' 'inserted in the shoe its iai' as practicable, by hand, and thenl the heelpart isturned ldown to the position showjn in Fig. 1.. This rootement of the'heelpart in automatica ly fore# 11a my preferredv con struction, as 'shown in Figs. 1-4, still leaves? the forepart contracted, however, so that the" down-turning of 'the heolfart may readily' push the forepart forwar lining of the shoe forward with it.` thelast for carryin 'the we has thus been turned down into exl tended position'within the shoe, theoltxeritf"l toi' of t e plate 12 andif nessary completes the down-turning of saidplate b 'engaging the notch 31. also, `whereupon t Q-bolt 20 snaps upwardly behind the pin 1T and 'locks' the last rigidly in .expanded position, firmly supportingall parts of' the shoe, will! rasees downwardly upon the: notch 30' be seen that; although I have. ln'ovided a compound hinge plate, in whieh the part |23 is capable ol' operation independently ot' the parl ll, or both parts It and l2 may be op eraled together at will, vet the last does not require any more transverse pins than t'ormerly. and yet the binge plates or eomponnd `ronneetion lie all in one 'and the same plane so as' to oeoupy the same narrow parallelsided kerfs. Thi,4 gives great. strength to the last and also eeonomy of mannt'aeture, and prevents the parts beeoming laterall)v diseonneeted or bent and broken.

The eonstrnetion shown in Figs. tL-Is| is put together in general the same as already deserihed for the preferred eonstrnetion, exeepting that there is only one plate to be plaeed, said plate reeeiving its bolt and spring in substantially the way already de'- seribed in the other eonsirnetion.
