While the invention is herein illustrated asapplied to a machine of the character shown in that application, which is a machine for lasting shoe it lo will be understood that it is not limited to machines of that particular kind.
- the invention in one aspect, provides a toe rest and an instep support and novel means forcontrolling them in such manner as to perm'it them to adjust themselves to the shoe "by relative movement heightwise of the shoe.
- the toe rest and the instep support are controlledjby fluid-operated means comprising cylinders and pistons therein for moving them respectively into their shoe-supporting positions while permitting them thus to adjust themselveslto the shoe, the cylinders being in communication with each other and the admission of the fluid thereto being con- 1 trolledby a valve common toboth or them.
- the cylinder and piston associated with the toerest are of greater diameter than thecylinder and piston associated with the instep support, so that adequate pressure is applied by the toe rest to clamp the shoe against a member engaging the bottom of its forrepart while any 7, danger of tipping the shoe by thegpressure of the instep support thereon is avoided.
- the operating fluid is a liquid, such .as light oil, and to cause lthe toe rest and the instep support to control the shoe in a substantially positive manner after their engagement with it, theinvention provides for locking the fluid in'the operating means.

They include wipers 2 for wiping the marginal portion of the up erinvvardly over an insole on the "last and for pressing it down on the insole.
- the shoe is positionedin proper rel ltion to these instrumentalitiesfby a member 3 which engages the bottom of the toe end of the insole ,andihya plurality of pins 4 which extend throughlholesfin the insole intoholes provided in the last.
- a heel rest I is moved lengthwise of the shoe into engagement with its heel-end face to assist in supporting it against displacement in a heelward direction in the lasting operation.
- the toe rest comprises a rubber pad I2 arranged to engage the top of the toe end of the upper and a metal holder I4 for the pad, this holder having a lower end portion formed to lit in a cylinder I6 which is part of a casting I8 secured at its lower end to a frame casting 20.
- a depending portion 22 of the holder I4 extends into a bore in a piston 24 movable in the cylinder I6 and is connected rigidly to the piston by a cross pin 26 which extends into slots 28 formed in opposite sides of the cylinder.
- the toe rest 6 and the piston 24 are thus movable as a unit between limits determined by the pin 26 and the slots 28, the means for thus limiting upward movement of the parts being effective in case there is no shoe in the machine.
- Upward movement of the toe rest into clamping position results from the admission of fluid, preferably light oil, to the cylinder I6 through a pipe line 30 which leads from a chamber 32 (Fig. 2)' to which fluid is supplied under pressure from a reservoir 33 (Fig. as fully disclosed in the previously mentioned application.
- Such movement of the toe rest is effected against the resistance of a pair of springs 34, one of which is shown in Fig. 1, connected to the ends of the pin 26 and to the base of the cylinder I6. It will be understood that these springs serve, when permitted, to return the toe rest to its initial position.
- the instep support 8 also is operated by fluid from the pipe line 30.
- a block 36 which engages the instep portion of the'upp'er or the last, the block being preferably made of wood to provide a positive support without danger of injuring the upper by contact therewith and being mounted on the upper end of a rod 38 which serves as a piston vertically movable in a cylinder 40 formed as part of the casting I8 and communicating at its lower end through a passage 42 with the cylinder I6.
- The'block 36 has a concave face 44 which substantially fits a convex face on the holder I4 to prevent the block from turning.
- a pin 46 extends from the holder I4 into a slot 48 in the block 36 to serve by engagement with a plate 50 pinned to the piston 38 to prevent any accidental movement of the piston entirely out of the cylinder 40.
- the piston 38 is of much smaller diameter than the piston 24, and accordingly the instep support is forced against the shoe or last with less pressure than the toe rest to avoid any tipping of the shoe by the action of the instep support thereon.
- the instep support when permitted, is returned to its initial position by a pair of springs 52 at opposite sides of the cylinder 40.
- the plate 50 serves by engagement with the upper end of the cylinder to limit the downward movement of the instep support.
- the above-mentioned chamber 32 is formed in a casting 54 shown fragmentarily in Fig. 2, this casting being fast on a plate 56 which serves as a closure for the chamber.
- the admission of fluid to the cylinders I6 and40 for operating the toe rest and the instep support and the exhaust of fluid from the cylinders are controlled by a sleeve valve 58 which is slidingly movable on a tube 60 clamped tightly between the casting 54 and a coupling 62 communicating with the pipe line 30.
- the tube 60 has therein a partition 64 which closes communication between its opposite sides of this partition respectively are two sets of ports 66 and 68.
- the valve 58 is provided with an annular chamber I0 through which the ports 66 and 68 are in communication with each other when the valve is in position to admit fluid from the chamber 32 to the cylinders I6 and 40.
- the valve is positioned initially against the casting 54, as shown in Fig. 2, with the ports 68 open to exhaust.
- the valve is controlled by an arm I2 ends, and extending through the tube at opposite which is pivotally mounted at its upper end on a pin I4 supported on a bracket I6 fast on the plate 56. At its lower end the arm carries a pin the arm I2 holds the valve in its normal position against the casting 54.
- a lever 04 between one arm of which and a lug 86 on the arm 12 is a compression spring 88.
- the arm I2 is operated to move the valve 58 into position to open communication between the ports 66 and 68 in response to swinging movement of the lever 84 in a clockwise direction with reference to Fig. 2, the movement of the arm being limited by its engagement with a rod 90 threaded in the plate 56.
- the spring 88 is stronger than the spring 82 and may yield only after engagement of the arm I2 with the rod 90.
- the valve 58 is prevented from returning to its starting position by a latch 92 which is pivotally mounted on the lever and is arranged to engage a shoulder 94 formed on a plate 96 pivotally mounted on a pin 98 on the bracket I6.
- the plate is adjustable about the pin 98 by a screw I00 bearing on the plate 56 and is held in adjusted position by a screw I02 threaded in the bracket 16.
- the lever 84 is operated to move the valve 58 into position to establish communication between the ports 66 and 68 by a segmental member I04' adjustably secured to a rotatable control shaft I06 with which the machine is provided. 6
- the member I04 has an inclined face I08 which by engagement with a roll IIO on the lever 84'thus operates the lever and has also an arcuate face II2 concentric with the shaft I06 'for engaging the roll thereafter to maintain the valve 58 in the position in which it establishes communica tion between the chamber 32 and the pipe line 30.
- the latch 92 When the valve is in this position, determined by engagement of the arm 12 with the rod 90', the latch 92 is positioned over the shoulder 94 by a spring II4 connected to an arm II6 of the latch, but is spaced above the shoulder.
- the spring 82 moves the valve 58 reversely to 'a position determined by engagement of the latch with the shoulder.
- a portion thereof covers the ports 88, as illustrated by broken lines in Fig. 2, thereby locking the fluid in the pipe line 30 and in the cylinders I6 and 40 to hold the: toe rest andthe ports 68 and thus to cause the toe rest and the instep support to be returned to their starting positions.
- Fastened to the blocksby screws I28 is a strip-of leather I30 arranged to serve as a cover for the blocks andto engage the end face of the shoe.
- the holder I26 is mounted to swing about two pins I32 which are fast in the-arms I34 of a yoke member I36.
- the inner ends of the pins I32 are V-shaped and extend between the two blocks I22 tolimit turning movements of these blocks about the axes of the pins I24 and also by engagement with the blocks to limit turning movement of the holder I26 about the pins I32. It will be under stood that upon engagement of the heel rest with the shoe the holder I26 may turn aboutthe pins I32 and the blocks I22 may turn about their own axes to conform to the contour of the heel end face of the shoe heightwise of the shoe.
- the hub of the yoke member I36 is fast on the reduced front end of a rod I38 mounted in a socket formed in a carrier I46 which is fast on a shaft I42 the ends of which are mounted to turn in bearings formed i-n'plates M lfast on the frame casting 253, 0nly one of these plates being visible in the drawings.
- the rod I38 may be adjusted lengthwise in the carrier I40 for shoesof different sizes or shapes, and it is held in adjusted position and also heldfrom turningbya pin I46 arranged to enter any one of a plurality of holes I48 in the rod. The pin may be withdrawn from any one of the'holes against the resistance of a spring I50 by means of a knob I52 fast on the pin.
- Swinging movement of the carrier I40 about the axis of the shaft I42 to apply the heel rest to the shoe is effected by a pair of pistons I54 which are movable in cylinders I55 spaced apart laterally of the shoe and are connected by rods I58 to arms I50 which are parts of the carrier I40 and extend through openings in the frame casting 20, only one of these arms being visible in the drawings.
- the carrier I40 is thus operated by balanced forces applied in different locations along its axis while providing room for the casting I8 directly under the toe rest and the instep support.
- One of the cylinders I56 is shown in Fig. 1, and both cylinders are shown diagrammatically in Fig. 5. They are supplied with fluid from the chamber 32 through a pipe line I62.
- valve I68 is moved first to admit fluid to the cylinders I56 by establishing communication between two sets of ports I10 and I12, thereby causing the heel rest to be moved into engagement with the shoe. Thereafter, by a partial reverse movement the valve covers the ports I12, as illustrated by broken lines in Fig. 5,.and thereby locks the fluid in the cylinders I56 to render the heel rest substantially positive in its control of the shoe. Later in the cycle the valve is returned to itsinitial position against the casting 54 to releasethe fluid from the cylinders by uncovering the ports I12 and thus to permit the heel rest to return to its initial position.
- the mechanismfor thus operating the valve I68 is not shown in the drawings, since it is essentially of the same construction as the mechanism shown in Fig. 2 for controlling the valve-58. 6

This invention relates to shoe-supporting means for shoe machines, this application being adivision of a copending application of mine for Letters Patentfor improvements in Machines for use in .the manufacture of shoes, Serial No. 377,347, filed on February 4, '1941. While the invention is herein illustrated asapplied to a machine of the character shown in that application, which is a machine for lasting shoe it lo will be understood that it is not limited to machines of that particular kind.
V For supporting ashoe and its last,herein 'frequently referred to inclusively as the shoe,'against pressure-applied on the "bottom of the shoe, the invention, in one aspect, provides a toe rest and an instep support and novel means forcontrolling them in such manner as to perm'it them to adjust themselves to the shoe "by relative movement heightwise of the shoe. As herein illustrated, the toe rest and the instep support are controlledjby fluid-operated means comprising cylinders and pistons therein for moving them respectively into their shoe-supporting positions while permitting them thus to adjust themselveslto the shoe, the cylinders being in communication with each other and the admission of the fluid thereto being con- 1 trolledby a valve common toboth or them. 'Preferably, as shown, the cylinder and piston associated with the toerest are of greater diameter than thecylinder and piston associated with the instep support, so that adequate pressure is applied by the toe rest to clamp the shoe against a member engaging the bottom of its forrepart while any 7, danger of tipping the shoe by thegpressure of the instep support thereon is avoided. Preferably the operating fluid is a liquid, such .as light oil, and to cause lthe toe rest and the instep support to control the shoe in a substantially positive manner after their engagement with it, theinvention provides for locking the fluid in'the operating means.
The inventioniurther provides novel meansfor supporting the-shoe by-engagement'with its-heelend face. For this purpose, the construction 7 shown 'comprisesa heel rest "having members arrangedto press on the heel-endface of :the shoe respectively in difierent locations heightwise =of theshoe, these members being movable relatively to eachother about different axes extending lat.-
.erally of the shoe and movable also as a *unit substantially positive .manner in that position by control of the operating fluid.
'The above and other features of the invention, including various novel details or construction andcombinations of parts, will now be more particularly described with reierenoe to the accompanyi-ng drawings and thereafter pointed out in the claims. I

ma hin shown in t e p eviou. 1y men tioned app a i is a la n m hine t e-vine various lasting 'instrumentalities which cooperate to last the toe end of a shoe positioned bottom up ard, some of wh ch ns rum nt lii s e e sho n igbu ne d ot th pa u arl .b t scribed for an understanding of flthe present i vention. They include wipers 2 for wiping the marginal portion of the up erinvvardly over an insole on the "last and for pressing it down on the insole. The shoe is positionedin proper rel ltion to these instrumentalitiesfby a member 3 which engages the bottom of the toe end of the insole ,andihya plurality of pins 4 which extend throughlholesfin the insole intoholes provided in the last. [The operator mounts jthe ,shoe on the pins "4 with the insole in engagement Withjihe any downwa d ovement in res ons p m example, to pressure of'the wipers "2 thereon,'and
a heel rest I is moved lengthwise of the shoe into engagement with its heel-end face to assist in supporting it against displacement in a heelward direction in the lasting operation. The toe rest comprises a rubber pad I2 arranged to engage the top of the toe end of the upper and a metal holder I4 for the pad, this holder having a lower end portion formed to lit in a cylinder I6 which is part of a casting I8 secured at its lower end to a frame casting 20.
A depending portion 22 of the holder I4 extends into a bore in a piston 24 movable in the cylinder I6 and is connected rigidly to the piston by a cross pin 26 which extends into slots 28 formed in opposite sides of the cylinder. The toe rest 6 and the piston 24 are thus movable as a unit between limits determined by the pin 26 and the slots 28, the means for thus limiting upward movement of the parts being effective in case there is no shoe in the machine. Upward movement of the toe rest into clamping position results from the admission of fluid, preferably light oil, to the cylinder I6 through a pipe line 30 which leads from a chamber 32 (Fig. 2)' to which fluid is supplied under pressure from a reservoir 33 (Fig. as fully disclosed in the previously mentioned application. Such movement of the toe rest is effected against the resistance of a pair of springs 34, one of which is shown in Fig. 1, connected to the ends of the pin 26 and to the base of the cylinder I6. It will be understood that these springs serve, when permitted, to return the toe rest to its initial position. The instep support 8 also is operated by fluid from the pipe line 30. It comprises a block 36 which engages the instep portion of the'upp'er or the last, the block being preferably made of wood to provide a positive support without danger of injuring the upper by contact therewith and being mounted on the upper end of a rod 38 which serves as a piston vertically movable in a cylinder 40 formed as part of the casting I8 and communicating at its lower end through a passage 42 with the cylinder I6. The'block 36 has a concave face 44 which substantially fits a convex face on the holder I4 to prevent the block from turning. .A pin 46 extends from the holder I4 into a slot 48 in the block 36 to serve by engagement with a plate 50 pinned to the piston 38 to prevent any accidental movement of the piston entirely out of the cylinder 40. The piston 38 is of much smaller diameter than the piston 24, and accordingly the instep support is forced against the shoe or last with less pressure than the toe rest to avoid any tipping of the shoe by the action of the instep support thereon. The instep support, when permitted, is returned to its initial position by a pair of springs 52 at opposite sides of the cylinder 40. The plate 50 serves by engagement with the upper end of the cylinder to limit the downward movement of the instep support.
The above-mentioned chamber 32 is formed in a casting 54 shown fragmentarily in Fig. 2, this casting being fast on a plate 56 which serves as a closure for the chamber. The admission of fluid to the cylinders I6 and40 for operating the toe rest and the instep support and the exhaust of fluid from the cylinders are controlled by a sleeve valve 58 which is slidingly movable on a tube 60 clamped tightly between the casting 54 and a coupling 62 communicating with the pipe line 30. The tube 60 has therein a partition 64 which closes communication between its opposite sides of this partition respectively are two sets of ports 66 and 68. The valve 58 is provided with an annular chamber I0 through which the ports 66 and 68 are in communication with each other when the valve is in position to admit fluid from the chamber 32 to the cylinders I6 and 40. The valve is positioned initially against the casting 54, as shown in Fig. 2, with the ports 68 open to exhaust. The valve is controlled by an arm I2 ends, and extending through the tube at opposite which is pivotally mounted at its upper end on a pin I4 supported on a bracket I6 fast on the plate 56. At its lower end the arm carries a pin the arm I2 holds the valve in its normal position against the casting 54. Also pivotally mounted on the pin I4 is a lever 04 between one arm of which and a lug 86 on the arm 12 is a compression spring 88. Through this spring the arm I2 is operated to move the valve 58 into position to open communication between the ports 66 and 68 in response to swinging movement of the lever 84 in a clockwise direction with reference to Fig. 2, the movement of the arm being limited by its engagement with a rod 90 threaded in the plate 56. The spring 88 is stronger than the spring 82 and may yield only after engagement of the arm I2 with the rod 90. After being operated by the lever 84 the valve 58 is prevented from returning to its starting position by a latch 92 which is pivotally mounted on the lever and is arranged to engage a shoulder 94 formed on a plate 96 pivotally mounted on a pin 98 on the bracket I6. The plate is adjustable about the pin 98 by a screw I00 bearing on the plate 56 and is held in adjusted position by a screw I02 threaded in the bracket 16. The lever 84 is operated to move the valve 58 into position to establish communication between the ports 66 and 68 by a segmental member I04' adjustably secured to a rotatable control shaft I06 with which the machine is provided. 6 The member I04 has an inclined face I08 which by engagement with a roll IIO on the lever 84'thus operates the lever and has also an arcuate face II2 concentric with the shaft I06 'for engaging the roll thereafter to maintain the valve 58 in the position in which it establishes communica tion between the chamber 32 and the pipe line 30. When the valve is in this position, determined by engagement of the arm 12 with the rod 90', the latch 92 is positioned over the shoulder 94 by a spring II4 connected to an arm II6 of the latch, but is spaced above the shoulder. When the segmental member I04 passes beyond the roll, N0, the spring 82 moves the valve 58 reversely to 'a position determined by engagement of the latch with the shoulder. When the valve is in this po sition a portion thereof covers the ports 88, as illustrated by broken lines in Fig. 2, thereby locking the fluid in the pipe line 30 and in the cylinders I6 and 40 to hold the: toe rest andthe ports 68 and thus to cause the toe rest and the instep support to be returned to their starting positions.
The heel rest I which further assists in controlling the-shoe comprises two blocks I22 mounted on pins I24 the ends of which are rotatable in bearings in the two arms of a U-shaped member I26 which serves as a holder for the blocks. Fastened to the blocksby screws I28 is a strip-of leather I30 arranged to serve as a cover for the blocks andto engage the end face of the shoe. The holder I26 is mounted to swing about two pins I32 which are fast in the-arms I34 of a yoke member I36. The inner ends of the pins I32 :are V-shaped and extend between the two blocks I22 tolimit turning movements of these blocks about the axes of the pins I24 and also by engagement with the blocks to limit turning movement of the holder I26 about the pins I32. It will be under stood that upon engagement of the heel rest with the shoe the holder I26 may turn aboutthe pins I32 and the blocks I22 may turn about their own axes to conform to the contour of the heel end face of the shoe heightwise of the shoe. The
hub of the yoke member I36 is fast on the reduced front end of a rod I38 mounted in a socket formed in a carrier I46 which is fast on a shaft I42 the ends of which are mounted to turn in bearings formed i-n'plates M lfast on the frame casting 253, 0nly one of these plates being visible in the drawings. The rod I38 may be adjusted lengthwise in the carrier I40 for shoesof different sizes or shapes, and it is held in adjusted position and also heldfrom turningbya pin I46 arranged to enter any one of a plurality of holes I48 in the rod. The pin may be withdrawn from any one of the'holes against the resistance of a spring I50 by means of a knob I52 fast on the pin.
Swinging movement of the carrier I40 about the axis of the shaft I42 to apply the heel rest to the shoe is effected by a pair of pistons I54 which are movable in cylinders I55 spaced apart laterally of the shoe and are connected by rods I58 to arms I50 which are parts of the carrier I40 and extend through openings in the frame casting 20, only one of these arms being visible in the drawings. The carrier I40 is thus operated by balanced forces applied in different locations along its axis while providing room for the casting I8 directly under the toe rest and the instep support. One of the cylinders I56 is shown in Fig. 1, and both cylinders are shown diagrammatically in Fig. 5. They are supplied with fluid from the chamber 32 through a pipe line I62. In case there is no shoe in the machine, swinging movement of the carrier I40 in response to movements of the pistons I54 is limited by engagement of a shoulder I64 thereon with the frame casting 20. When fluid is permitted to exhaust from the cylinders I56 the heel rest and its carrier are returned to their initial positions by gravity, their movement being limited by engagement of a shoulder I66 on the carrier with the frame casting. Admission of fluid to the cylinders I56 and exhaust of fluid therefrom are controlled by a valve I68 (Fig. 5) which is of the same construction and operates in the same manner as the valve 58 for controlling the movements of the toe rest and the instep support. That is, the valve I68 is moved first to admit fluid to the cylinders I56 by establishing communication between two sets of ports I10 and I12, thereby causing the heel rest to be moved into engagement with the shoe. Thereafter, by a partial reverse movement the valve covers the ports I12, as illustrated by broken lines in Fig. 5,.and thereby locks the fluid in the cylinders I56 to render the heel rest substantially positive in its control of the shoe. Later in the cycle the valve is returned to itsinitial position against the casting 54 to releasethe fluid from the cylinders by uncovering the ports I12 and thus to permit the heel rest to return to its initial position. The mechanismfor thus operating the valve I68 is not shown in the drawings, since it is essentially of the same construction as the mechanism shown in Fig. 2 for controlling the valve-58. 6
