- the object of this invention is to provide a last designed especially for use in lasting and similar machines, but whose features of construction are susceptible of embodiment in followers, stretchers, display-forms for shoes, &c.; and to this end my invention consists in the last, follower, stretcher, display-form, or like structure having the construction substantially as hereinafter set forth.
- my aim has been to provide a last capable of easy separation from and insertion into the shoe, which shall have ample strength, and to provide a last which shall embody any or allof the features of being easily unlocked at the instant of the separation of the last and shoe, such unlocking being possible without the use of the hands, so as to leave them free for manipulating the shoe, of being automatically ex tensible and self-locking, not only against collapse, but also against strains tending to move its parts farther apart than their extended positions, of having a separable or easily-removable fore part, and of having a construc tion by which anvil-heel seats of various sizes and shapes can be used.
- Figs. 1 to 13, inclusive I show such a last that is divided, so that the fore part A has a rear face A, the plane of which is preferably perpendicular to the length of the last;
- the heel part B has a short vertical face B at its front lower portion, which face when the last is extended abuts against the rear face A of the fore part A, and the front face 13 of the heel part above the short vertical face inclines backward and upward in a transverse plane.
- the opposite surfaces of the fore and heel parts may, however, be given any de sired shape or inclination, so long as a recess is formed between them when the last is extended.
- My connection between the fore and heel parts causes the heel part B to turn on or substantially on the line b where the planes of the vertical and inclined portions B and B meet or intersect the planes of the front face of the heel part and enables that line b to be located low in the last, thereby securing the great shortening of the last that is due to the low center of movement of the heel part.
- connection I employ between the fore and heel parts consists, in general, of two substantially-vertical longitudinal plates, one of which, (J, is attached to the fore part and extends across the recess between the fore and heel parts and preferably, although not necessarily, into a slot B in the heel part, and the other of which plates D is secured to the heel part B, overlaps the forepart plate 0, and preferably, although not necessarily, extends into a slot A in the fore part.
- These plates C and D are connected together, preferably by a hinge connection, at or about the line of meeting between planes of the two surfaces B and B on the front face of the heel part B.
- the vertical surfaces A and B on the fore and heel parts abut below the hinge-center and prevent the portions of the last parts above the hinge-center from moving farther apart than their normal pos'ition.
- the plates and' D which are connected to the parts of the last and extend into or across the recess between the parts of the last when the last is extended, can be made to abut against each other and not overlap when the last is extended, or they can overlap and not extend into recesses in the parts of the last opposite those to which they are attached, respectively, when the last is extended, or one of such plates can span the recess and enter a slot in the opposite part of the last while the second plate merely extends into the recess, but not into a slot in the part of the last opposite that part to which the second plate is attached when the last is extended, or a single plate can be used, which plate can extend across the recess and into a slot in the part of the last opposite that to whichsaid plate is attached when the last is extended, or a single plate can be used, which
- My invention includes all of the above-stated constructions and includes any last having a portion removed between the fore and heel parts, forming a recess lying transversely of the last when extended and having a plate or other strengthening part having considerable width, which plate or other strengthening part projects from one wall of the recess or is attached to one of the parts of the last, and said last being so con- 'st-ructed that said plate or strengthening part can directly or indirectly engage the wall of the recess or the part of the last opposite that wall or part from which it-projects or to which it is attached, respectively.
- any number of pairs which extend into or across the recess or any number of such plates used singly can be employed.
- the fore and heel part plates are preferably formed separate from and are attached to the last parts, and they are preferably formed of metal; but they can, if desired, 'be integral with the last parts.
- said plate is provided with an arc-shaped flange G on its outer face-11 e., the face op.- posite to the heel-part plate-and this flange C fits into an arc-shaped groove A formed in the wall-of a slot A in the fore part A. Teeth O and 0 formed on the arc-shaped flange O, bite into the wood in the groove A and prevent the flange from turning in the groove.
- the plate 0 is held with the flange Oin the groove A by a wedge E, that also occupies the slot A and that is semicircular in form and tapers from top to bottom and from the rear edge toward the front, although itis not necessary to have it taper in both these directions.
- the wall A of the slot A in the fore part is inclined tofit the wedge E and is out out at a to permit sufficient lateral movement of the heel-part plate, so that the arcshaped flange on the fore-part plate can enter the slot A until it is opposite the arc-shaped groove A
- the opposite wall of the slot A and the wedge E are cut out to permit proper movement of the enlarged ends of the arms on the locking-piece.
- the wedge E is also reoessed at e to permit movement of the heelbent up into a spring-handle E a portion of whose free end E engages a notch O inthe fore-part hinge-plate 0, thus locking the wedge E in place and through it the fore-part hinge-plate G.
- the flange E and springhandle E can, if desired, be formed of a strip C of spring-steel, as shown in Fig. 16, and may be fastened to the wedge E by having holes E and E formed in it and lugs E and E formed on the wedge E, the lugs being passed through the holes and headed over.
- the wedge E can be inserted and removed by hand, thus providing convenient means for readily removing one fore part and substituting another.
- the difference between lasts of the same size, but of different styles, lies almost entirely in the shape of the toe, and one heel part can thus with my means for detachably securing the fore part thereto be used with any number of fore parts.
- the fore-part plate 0 is hinged to the heelpart plate D by a rivet F, which occupies-oppositely-countersunk holes in said plates, its ends being preferably flush with the outer faces of said plates, as shownin Fig. 3.
- Each of these plates Oand D is provided with aslot G above the hinge, each of which slots G and G has a straight wall G on the side toward the outer edge of the plate and an. opposite wall G that is straight at the top only for a very short distance,from which point it sweeps out in a compound curve or in an oblique line, as preferred, and around to the straight wall.
- One of the slots G may, if preferred, have both of its walls straight.
- a vertical hole H is bored to receive the jack-pin socket I.
- Ahorizontal and a vertical saw-cut K and L are made, thus removing material to form a socket for the anvil-heel seat N, and a vertical slot B is made from the jack-pin-socket hole H forward to the front face B of the heel part, but leaving a portion M, of wood, uniting the two sides of the heel part at its front upper corner.
- the heel-part plate D, jack-pin socket I, and the anvil-heel seat N are all preferably formed in one piece and when so made are formed, preferably, by forging.
- the forging is made as thick as the two plates together,thus forming a web 0, uniting the heel-part plate to the j ack-pin socket.
- the web 0 is extended down to the top of the anvil-heel seat N.
- Ablock P on the web fills the slot from the front wall of the anvil-heel seat N to the vertical wall 13 of the heel part.
- a pin of wood Q is glued into holes in the parts B and B of the heel part,which are separated by the slot Win the heel part, and this pin passes through an alined hole 0 in the web 0.
- the pin Q fastens the forging in the heel part and firmly unites the wood of the front lower portions B and B of the heel part B where they are separated by the web 0.
- the anvil-heel seat N is formed separately from the jack-pin socket I, so that such heel-seats of different sizes and styles can be used with the same hinge mechanism.
- the jack-pin socket I is formed with a flaring portion I. near its lower end, which portion forms a shonlder,against which the anvil-heel seat N can firmly rest.
- Below the flaring portion 1' of the jack-pin socket I is a cylindrical portion 1 at the lower end of which is an annular lip I
- the anvil-heel seat N is provided with a circular countersunk hole N. In fastening the anvil-heel seat it is placed over the lower cylindrical end I of the jack-pin socket I and against elliptical in vertical cross-section.
- the lower end I of the jack-pin socket M is then expanded or upset in the countersunk hole N in the anvil-heel seat N.
- a plug of wood R is dropped into the lower end of the anvilheel seat N and is fastened in place by turning the annularlip 1 before mentioned.
- the web 0 affords a support for the front portion of the anvil-heel seat N, and. the block P prevents its turning on the jack-pin socket I.
- a locking-piece S occupies the slots G and G in the fore and heel part plates 0 and D and serves to lock the parts A and B of the last both against strains tending to collapse the last and against strains tending to move the said parts away from each other beyond their normal position.
- the locking-piece also acts to extend the last.
- Said locking-piece S con sists of a preferably-cylindrical pin S, occupying the slots G and G in the fore and heel part plates and connecting two parallel arms S and S which are enlarged at their forward ends S
- the fore part A is cut out ateach side of the slot A to allow the locking-piece arms S to play.
- the arms S are for the purpose of affording convenient means to move the locking-pin S, and for that purpose such arms S are most conveniently maintained in a substantially-horizontal position.
- the op-' posite faces S and S of the arms S and their enlarged ends S and S are in parallel planes and serve to hold the fore and heel part plates 0 and D together, thereby greatly stiffening or bracing them.
- the said faces S of the arms S are cut away at their middle portions S to reduce the friction on the plates.
- the rearends S of the arms S play between alined lugs 0 and 0 formed on opposite sides of the web 0, and the ends of a pin T, driven through a hole in the web 0.
- the locking-piece S is combined with the hinge-plates A and B by holding it with its arms S and S extended upward and threading one arm S through the superposed slots G and G in the plates 0 and D, preferably before the rivet F is put in place which forms the pivot of thehinge.
- the arms S and S of the locking-piece are then swung down to their normal position to rest on the lugs O and O on the web 0, and the pin T is driven into the hole in the web.
- the pin T and lugs O and 0 must be somewhat farther apart than the vertical thickness of the arms S and S; but a close fit may be had by making the arms S and S It will be seen that this locking-piece S can be forged at a single operation and requires no further finishing.
- the locking-piece S can, if desired, be made flaring at each end like the rivet F and the walls of the slots G and G be countersunk, in which case the locking-piece ends can be flush with the outer surfaces of the plates 0 and D and need not project beyond them.
- the particular means employed consist of a spring or springs U and U, preferablyone on each side of the web, which rest on the block P at the bottom of the web 0, extend in a curve around the wooden plug Q, and then extend forward and upward, where their upper ends are inserted in notches in the forward portions of the lower faces of the arms S and S of the locking-pieces S.
- the tops of'the slots G and G are so positioned with reference to the center I) of the hinge that when the pin S of the lockingpiece S occupies and consequently alines them the last parts are in normal extended position.
- the last is locked, for the pin is then in a portion of the slots where the walls are parallel and where they can consequently have no tendency to cam the pin to another position.
- the curve or curves at the bottoms of the slots G and G are full enough so that the pin S of the locking-piece S can remain between these curved walls G and G, and at the bottomof the slots when the last is collapsed.
- the curvature of the curved wall or walls G and G of the slots is such that when the pin S of the locking-piece S is forcibly raised it, through its action on the curved wall or walls G and 'G is caused to force the fore and heel part platesG and D apart, throwing the heel part B back into extended position and locking the last.
- I can, if desired, form the cam-surface G which serves to extend the last, di-' rectly on one of the last parts Aor B instead of on the connecting mechanism between these parts.
- I have shown the locking-piece S as having a movement away from the hinge center b to lock the last and as having a movement toward such center I) to unlock the last; but these movements could by properly shaping the slots G and G easily be reversed so that the locking-piece S should move toward the hinge center I) to lock the last and away from the center to unlock the last.
- I can also make the locking-piece S separate from the fore and heel part plates 0 and D-for instance, in the form of a pin or plugand can lock the last by passing such pin between surfaces or into openings or notches on the plates 0 and D after the last has been extended, or by tapering such pin or plug I can extend the last in the act of inserting the plug between said surfaces or into the said openings or notches.
- the plug can either be a connected part of the mechanism or can be entirely separate and removable, so that it is guided by the hand in being placed in position in the last. I can dispense with one plate 0 or D,
- the plates 0 and D in any or all of the forms described and used with any or all of the described forms of slots, locking-pieces, springs, &c., are capable of use in other relations.
- This locking-piece V consists principally of a cylindrical pin V, connecting two parallel arms V and V having vertical faces V and V that hold between them the hinge-plates.
- the vertical faces V and V of the parallel arms arecut away along their central portions V and V to reduce the friction.
- the arms V and V are provided with alined holes V and V through which holes and a roller V a pin V is thrust, after which its ends are headed over. This roller V travels in a slot G, formed in the heel-part hinge-plate W.
- a notched lug W is formed, in which rests one end of a spring X, the other end of which engages a notch V in one of the arms V of the lockin g-piece V.
- the connection between the rear ends of the arms V and V gives them greater strength to hold the fore and heel part plates against each other.
- the locking-piece S is forced toward the hinge center 17 against the action of the springs U and U and the fore and heel parts A and B are swung toward each other, thus materially shortening the last, and the last is withdrawn fromthe shoe.
- the springs U and U throw the locking-piece S upward, which latter by its action on the curved walls G and G of the slots G and G swings the fore and heel part plates 0 and D apart and with them the fore and heel parts A and B and extends the last.
- the locking-piece S then passes above the curved walls G and G and between the parallel straight walls, in which position it locks the last, thus automatically restoring it to proper position for having the parts of a shoe assembled thereon. If it is desired to insert the last into a finished or partly-finished shoe, the locking-piece S is forced far enough down in the slots G and Gabout half-way for the curved walls G and G to properly engage the pin S of the locking-piece S, when, if the heel part B be thrown toward the fore part A, the curved walls G and G will throw the pin Sof the locking-piece S the remainder of the distance to the bottom of the slots G and G. The last being now collapsed can be inserted into the shoe.
- a hook can be inserted into the recess between the fore and heel parts A and B and the locking-piece S be raised, or pressure can be applied to the heel part B to force it into extended position, and the springs U and U will raise the locking-piece S to locking position during such movement of the heel part.
- the end E of the spring E on the wedge E is raised out of the notch in the fore-part plate 0 and the wedge E is turned toward the heel part B and about the center of the arc-shaped flange C until the flange E on the wedge E is disengaged from the circular edge of the fore-part plate G, when the wedge E can be lifted out of the slot A in the fore part A.
- the fore part A is now moved laterally until the arc-shaped flange O on the fore-part plate is disengaged from the arc-shaped groove A in the fore-part slot A when the fore part A can be moved forward until it is clear of the fore-part plate 0.
- a reversal of these steps will fasten the fore part on the fore-part plate. It will be observed that the fore part does not require that any metal part be fastened permanently to it, so that there is no metal part to be furnished with a new fore part.
- the wedge which fastens the fore-part plate into the fore part can, if desired, be fastened in place merely by the friction caused by forcing it home, thus dispensing with the spring-catch on the wedge, which catch engages the notch on the fore-part plate.

To all ZU7'L0777/ it may concern:
7 Be it known that I, EDWIN J. PRINDLE, of Washington, in the District of Columbia, have invented certain new and useful Improvements in Lasts; and I do hereby declare that the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, inwhich Figure 1 represents a partial vertical longitudinal sectional view of my last. Fig. 2 represents a partial horizontal longitudinal sectional view of thelast shown in Fig. 1, the section being taken on the line a: as of said figure. Fig. 3 represents a vertical transverse sectional view, looking forward, of the last shown in Fig. 1, the section being taken on the line '3 y of said figure and the lockingpiece being omitted. Fig. at is a perspective View of the locking-piece. Figs. 5, 6, and 7 are a side elevation, a front elevation, and a top plan view, respectively, of the part comprising the heel-part plate, web, and jack-pin socket. Figs. 8, 9, and 10 are a side elevation, a front elevation, and a top plan View, respectively, of the fore-part plate. Figs. 11, 12, and 13 are a side elevation, a front elevation, and a top plan view, respectively, of the removable wedge. Fig. 14 is a perspective View of a modified form of wedge,its combined handle and flange being shown before attachment to the wedge. Fig. 15 is a perspective View of a modified form of last, and Fig. 16 is a perspective view of the lockingpiece used in the last shown in Fig. 15.
The object of this invention is to providea last designed especially for use in lasting and similar machines, but whose features of construction are susceptible of embodiment in followers, stretchers, display-forms for shoes, &c.; and to this end my invention consists in the last, follower, stretcher, display-form, or like structure having the construction substantially as hereinafter set forth.
In making my invention my aim has been to provide a last capable of easy separation from and insertion into the shoe, which shall have ample strength, and to provide a last which shall embody any or allof the features of being easily unlocked at the instant of the separation of the last and shoe, such unlocking being possible without the use of the hands, so as to leave them free for manipulating the shoe, of being automatically ex tensible and self-locking, not only against collapse, but also against strains tending to move its parts farther apart than their extended positions, of having a separable or easily-removable fore part, and of having a construc tion by which anvil-heel seats of various sizes and shapes can be used.
My improvements are capable of application to various forms of lasts; but it will be sufficient to illustrate the invention to show the same embodied in ahinged last. In Figs. 1 to 13, inclusive, I show such a last that is divided, so that the fore part A has a rear face A, the plane of which is preferably perpendicular to the length of the last; The heel part B has a short vertical face B at its front lower portion, which face when the last is extended abuts against the rear face A of the fore part A, and the front face 13 of the heel part above the short vertical face inclines backward and upward in a transverse plane. The opposite surfaces of the fore and heel parts may, however, be given any de sired shape or inclination, so long as a recess is formed between them when the last is extended. My connection between the fore and heel parts causes the heel part B to turn on or substantially on the line b where the planes of the vertical and inclined portions B and B meet or intersect the planes of the front face of the heel part and enables that line b to be located low in the last, thereby securing the great shortening of the last that is due to the low center of movement of the heel part. The connection I employ between the fore and heel parts consists, in general, of two substantially-vertical longitudinal plates, one of which, (J, is attached to the fore part and extends across the recess between the fore and heel parts and preferably, although not necessarily, into a slot B in the heel part, and the other of which plates D is secured to the heel part B, overlaps the forepart plate 0, and preferably, although not necessarily, extends into a slot A in the fore part. These plates C and D are connected together, preferably by a hinge connection, at or about the line of meeting between planes of the two surfaces B and B on the front face of the heel part B. The vertical surfaces A and B on the fore and heel parts abut below the hinge-center and prevent the portions of the last parts above the hinge-center from moving farther apart than their normal pos'ition. The plates and' D, which are connected to the parts of the last and extend into or across the recess between the parts of the last when the last is extended, can be made to abut against each other and not overlap when the last is extended, or they can overlap and not extend into recesses in the parts of the last opposite those to which they are attached, respectively, when the last is extended, or one of such plates can span the recess and enter a slot in the opposite part of the last while the second plate merely extends into the recess, but not into a slot in the part of the last opposite that part to which the second plate is attached when the last is extended, or a single plate can be used, which plate can extend across the recess and into a slot in the part of the last opposite that to whichsaid plate is attached when the last is extended, or a single plate can be used, which plate merely extends from one wall of the recess toward the opposite wall of said recess, but does not enter a slot in said opposite wall, means being provided whereby the plate can engage said opposite wall when the last is extended. My invention includes all of the above-stated constructions and includes any last having a portion removed between the fore and heel parts, forming a recess lying transversely of the last when extended and having a plate or other strengthening part having considerable width, which plate or other strengthening part projects from one wall of the recess or is attached to one of the parts of the last, and said last being so con- 'st-ructed that said plate or strengthening part can directly or indirectly engage the wall of the recess or the part of the last opposite that wall or part from which it-projects or to which it is attached, respectively. Instead of a single pair of plates any number of pairs which extend into or across the recess or any number of such plates used singly can be employed. While I have shown the plates as perpendicular to the axis of motion b, such plates can be placed in the last so that they are parallel to the axis of motion 19 and extend'across the recess between the last parts and are curved concentric to the axis of motion I).
strengthen the lastgive great strength tothe last to resist racking or twisting strains, such as occur during lasting, and when locked to each other or to the part of the lastopposite the part to whichthey are attached they furnish with the use of a minimum'amount. of metal or material a maximum strength to resist either strains tending to force the parts of the last apart beyond their normal extended positions or strains tending-to collapse the 'last.
the parts of the last, which parts have greater vertical than horizontal width at the instep, and of attachment to the jack-pin socket. The fore and heel part plates are preferably formed separate from and are attached to the last parts, and they are preferably formed of metal; but they can, if desired, 'be integral with the last parts.
To attach the fore-part plate 0 to the fore part, said plate is provided with an arc-shaped flange G on its outer face-11 e., the face op.- posite to the heel-part plate-and this flange C fits into an arc-shaped groove A formed in the wall-of a slot A in the fore part A. Teeth O and 0 formed on the arc-shaped flange O, bite into the wood in the groove A and prevent the flange from turning in the groove. The plate 0 is held with the flange Oin the groove A by a wedge E, that also occupies the slot A and that is semicircular in form and tapers from top to bottom and from the rear edge toward the front, although itis not necessary to have it taper in both these directions. The wall A of the slot A in the fore part is inclined tofit the wedge E and is out out at a to permit sufficient lateral movement of the heel-part plate, so that the arcshaped flange on the fore-part plate can enter the slot A until it is opposite the arc-shaped groove A The opposite wall of the slot A and the wedge E are cut out to permit proper movement of the enlarged ends of the arms on the locking-piece. The wedge E is also reoessed at e to permit movement of the heelbent up into a spring-handle E a portion of whose free end E engages a notch O inthe fore-part hinge-plate 0, thus locking the wedge E in place and through it the fore-part hinge-plate G. The flange E and springhandle E can, if desired, be formed of a strip C of spring-steel, as shown in Fig. 16, and may be fastened to the wedge E by having holes E and E formed in it and lugs E and E formed on the wedge E, the lugs being passed through the holes and headed over. The wedge E can be inserted and removed by hand, thus providing convenient means for readily removing one fore part and substituting another. The difference between lasts of the same size, but of different styles, lies almost entirely in the shape of the toe, and one heel part can thus with my means for detachably securing the fore part thereto be used with any number of fore parts. The
cost of adapting a last to a different fashion is thus reduced to the mere cost of a fore part. Moreover, the wear on a last comes almost entirely on the fore part, especially when the anvil-heel seat is used, so that by my mechanism the life of the last is increased many times solely at the cost of new fore parts. My detachable fore part thus results in great economy.
The fore-part plate 0 is hinged to the heelpart plate D by a rivet F, which occupies-oppositely-countersunk holes in said plates, its ends being preferably flush with the outer faces of said plates, as shownin Fig. 3. Each of these plates Oand D is provided with aslot G above the hinge, each of which slots G and G has a straight wall G on the side toward the outer edge of the plate and an. opposite wall G that is straight at the top only for a very short distance,from which point it sweeps out in a compound curve or in an oblique line, as preferred, and around to the straight wall. One of the slots G may, if preferred, have both of its walls straight.
In the heel part a vertical hole H is bored to receive the jack-pin socket I. Ahorizontal and a vertical saw-cut K and L are made, thus removing material to form a socket for the anvil-heel seat N, and a vertical slot B is made from the jack-pin-socket hole H forward to the front face B of the heel part, but leaving a portion M, of wood, uniting the two sides of the heel part at its front upper corner. The heel-part plate D, jack-pin socket I, and the anvil-heel seat N are all preferably formed in one piece and when so made are formed, preferably, by forging. Back of the portion where the fore-part plate overlaps the heel-part plate the forging is made as thick as the two plates together,thus forming a web 0, uniting the heel-part plate to the j ack-pin socket. The web 0 is extended down to the top of the anvil-heel seat N. Ablock P on the web fills the slot from the front wall of the anvil-heel seat N to the vertical wall 13 of the heel part. A pin of wood Q is glued into holes in the parts B and B of the heel part,which are separated by the slot Win the heel part, and this pin passes through an alined hole 0 in the web 0. The pin Q, fastens the forging in the heel part and firmly unites the wood of the front lower portions B and B of the heel part B where they are separated by the web 0. The anvil-heel seat N is formed separately from the jack-pin socket I, so that such heel-seats of different sizes and styles can be used with the same hinge mechanism. The jack-pin socket I is formed with a flaring portion I. near its lower end, which portion forms a shonlder,against which the anvil-heel seat N can firmly rest. Below the flaring portion 1' of the jack-pin socket I is a cylindrical portion 1 at the lower end of which is an annular lip I The anvil-heel seat N is provided with a circular countersunk hole N. In fastening the anvil-heel seat it is placed over the lower cylindrical end I of the jack-pin socket I and against elliptical in vertical cross-section.
the shoulder formed by the flaring portion I. The lower end I of the jack-pin socket M is then expanded or upset in the countersunk hole N in the anvil-heel seat N. To provide for the heel-tack of the insole, a plug of wood R is dropped into the lower end of the anvilheel seat N and is fastened in place by turning the annularlip 1 before mentioned. The web 0 affords a support for the front portion of the anvil-heel seat N, and. the block P prevents its turning on the jack-pin socket I.
A locking-piece S occupies the slots G and G in the fore and heel part plates 0 and D and serves to lock the parts A and B of the last both against strains tending to collapse the last and against strains tending to move the said parts away from each other beyond their normal position. The locking-piece also acts to extend the last. Said locking-piece S con sists of a preferably-cylindrical pin S, occupying the slots G and G in the fore and heel part plates and connecting two parallel arms S and S which are enlarged at their forward ends S The fore part A is cut out ateach side of the slot A to allow the locking-piece arms S to play. The arms S are for the purpose of affording convenient means to move the locking-pin S, and for that purpose such arms S are most conveniently maintained in a substantially-horizontal position. The op-' posite faces S and S of the arms S and their enlarged ends S and S are in parallel planes and serve to hold the fore and heel part plates 0 and D together, thereby greatly stiffening or bracing them. The said faces S of the arms S are cut away at their middle portions S to reduce the friction on the plates. The rearends S of the arms S play between alined lugs 0 and 0 formed on opposite sides of the web 0, and the ends of a pin T, driven through a hole in the web 0. The locking-piece S is combined with the hinge-plates A and B by holding it with its arms S and S extended upward and threading one arm S through the superposed slots G and G in the plates 0 and D, preferably before the rivet F is put in place which forms the pivot of thehinge. The arms S and S of the locking-piece are then swung down to their normal position to rest on the lugs O and O on the web 0, and the pin T is driven into the hole in the web. If the upper and lower surfaces of the arms S and S are parallel, the pin T and lugs O and 0 must be somewhat farther apart than the vertical thickness of the arms S and S; but a close fit may be had by making the arms S and S It will be seen that this locking-piece S can be forged at a single operation and requires no further finishing. The locking-piece S can, if desired, be made flaring at each end like the rivet F and the walls of the slots G and G be countersunk, in which case the locking-piece ends can be flush with the outer surfaces of the plates 0 and D and need not project beyond them.
Itis desirable to have the last automatic- The particular means employed consist of a spring or springs U and U, preferablyone on each side of the web, which rest on the block P at the bottom of the web 0, extend in a curve around the wooden plug Q, and then extend forward and upward, where their upper ends are inserted in notches in the forward portions of the lower faces of the arms S and S of the locking-pieces S.
The tops of'the slots G and G are so positioned with reference to the center I) of the hinge that when the pin S of the lockingpiece S occupies and consequently alines them the last parts are in normal extended position. When the pin S of the lockingpiece S is at the top of the slots G and G, the last is locked, for the pin is then in a portion of the slots where the walls are parallel and where they can consequently have no tendency to cam the pin to another position. The curve or curves at the bottoms of the slots G and G are full enough so that the pin S of the locking-piece S can remain between these curved walls G and G, and at the bottomof the slots when the last is collapsed. The curvature of the curved wall or walls G and G of the slots is such that when the pin S of the locking-piece S is forcibly raised it, through its action on the curved wall or walls G and 'G is caused to force the fore and heel part platesG and D apart, throwing the heel part B back into extended position and locking the last. I can, if desired, form the cam-surface G which serves to extend the last, di-' rectly on one of the last parts Aor B instead of on the connecting mechanism between these parts. 1
I have shown the locking-piece S as having a movement away from the hinge center b to lock the last and as having a movement toward such center I) to unlock the last; but these movements could by properly shaping the slots G and G easily be reversed so that the locking-piece S should move toward the hinge center I) to lock the last and away from the center to unlock the last. I can also make the locking-piece S separate from the fore and heel part plates 0 and D-for instance, in the form of a pin or plugand can lock the last by passing such pin between surfaces or into openings or notches on the plates 0 and D after the last has been extended, or by tapering such pin or plug I can extend the last in the act of inserting the plug between said surfaces or into the said openings or notches. The plug can either be a connected part of the mechanism or can be entirely separate and removable, so that it is guided by the hand in being placed in position in the last. I can dispense with one plate 0 or D,
using a single plate and using any of the above-described locking pieces or arrangements thereof.
The plates 0 and D in any or all of the forms described and used with any or all of the described forms of slots, locking-pieces, springs, &c., are capable of use in other relations.
The last shown in Fig. 15 differs from the last shown in the previous figures only as regards its locking-piece and the actuatingspring therefor. This locking-piece V consists principally of a cylindrical pin V, connecting two parallel arms V and V having vertical faces V and V that hold between them the hinge-plates. The vertical faces V and V of the parallel arms arecut away along their central portions V and V to reduce the friction. At their rear ends the arms V and V are provided with alined holes V and V through which holes and a roller V a pin V is thrust, after which its ends are headed over. This roller V travels in a slot G, formed in the heel-part hinge-plate W. On each side of the hinge-plate W a notched lug W is formed, in which rests one end of a spring X, the other end of which engages a notch V in one of the arms V of the lockin g-piece V. The connection between the rear ends of the arms V and V gives them greater strength to hold the fore and heel part plates against each other.
The operation of the form of last shown in the drawings is as follows: In the normal position of the last, into which position the parts of the last are thrown by the spring, the locking-piece S, owing also to the action of the spring, is at the top of the slots G and G.
'When it is desired to remove the last from a shoe, the locking-piece S is forced toward the hinge center 17 against the action of the springs U and U and the fore and heel parts A and B are swung toward each other, thus materially shortening the last, and the last is withdrawn fromthe shoe. As soon as the last is released the springs U and U throw the locking-piece S upward, which latter by its action on the curved walls G and G of the slots G and G swings the fore and heel part plates 0 and D apart and with them the fore and heel parts A and B and extends the last. The locking-piece S then passes above the curved walls G and G and between the parallel straight walls, in which position it locks the last, thus automatically restoring it to proper position for having the parts of a shoe assembled thereon. If it is desired to insert the last into a finished or partly-finished shoe, the locking-piece S is forced far enough down in the slots G and Gabout half-way for the curved walls G and G to properly engage the pin S of the locking-piece S, when, if the heel part B be thrown toward the fore part A, the curved walls G and G will throw the pin Sof the locking-piece S the remainder of the distance to the bottom of the slots G and G. The last being now collapsed can be inserted into the shoe. If the springs U and U should not be strong enough to raise the locking-piece S and extend the last, a hook can be inserted into the recess between the fore and heel parts A and B and the locking-piece S be raised, or pressure can be applied to the heel part B to force it into extended position, and the springs U and U will raise the locking-piece S to locking position during such movement of the heel part. When it is desired to detach the fore part A, the end E of the spring E on the wedge E, by means of the fingers applied to the handle E on the wedge E, is raised out of the notch in the fore-part plate 0 and the wedge E is turned toward the heel part B and about the center of the arc-shaped flange C until the flange E on the wedge E is disengaged from the circular edge of the fore-part plate G, when the wedge E can be lifted out of the slot A in the fore part A. The fore part A is now moved laterally until the arc-shaped flange O on the fore-part plate is disengaged from the arc-shaped groove A in the fore-part slot A when the fore part A can be moved forward until it is clear of the fore-part plate 0. A reversal of these steps will fasten the fore part on the fore-part plate. It will be observed that the fore part does not require that any metal part be fastened permanently to it, so that there is no metal part to be furnished with a new fore part. The wedge which fastens the fore-part plate into the fore part can, if desired, be fastened in place merely by the friction caused by forcing it home, thus dispensing with the spring-catch on the wedge, which catch engages the notch on the fore-part plate.
It will be observed that my connection between the fore and heel parts is such that the center of motion of the hinge does not have to occupy any precise relation to the heel and toe of the last, and consequently any size or shape of fore part can be used with a particular heel part. It will also be observed that, since the only requirement as to the transverse recess is that enough material shall be removed to allow the last to collapse to the desired extent, I am enabled to preserve the entire instep-curve on the top of the fore part, which is an advantage in assembling the parts of the shoe on the last in performing the operation of lasting the shoe and in removing the shoe from the last.
