When a hydraulic device is utilized to prevent the cushioning thereof, which will permit loosening of the shoe and slippage between the anvil and the swingable head of the machine, a locking means is provided, either automatically or manually actuated, to hold the anvil or last member rmly in position against the bottom of the head with the front portion of the shoe firmly gripped therebetween. In the form shownthe anvil 4or last member is locked into clamping position by a screw device provided with a hand' knob or wheel.

The contacting surface of the head vis preferablyV provided with a replaceable flat pressure series of diierent shapes and sizes of anvil mem-A bers for correspondingly different sizes and shapes of shoes, and also with a number of.iiat andembossed pressure plates which may be readily placed upon the top of the anvil member. These plates may be provided with suitable positioned and sized embossments. projections and elevations forshaping the shoe as Vmay be, desired-as for example to form depressions inthe sole of the shoe for one or all of the toes,'for boxing the shoes, for smoothing out the inner sole, for ren.

is prefer-I' ably hinged at one end to an upward extension" lthe piston 26 at 21.

To this end the leverage of the handle may be regulated to impart the desired pressures in back of the piston I5. For this purpose the handle includes a plurality of spaced annular grooves Il and these selectively cooperate with a shank 2l connected to and actuated by the manipulator Wheel I8', the shank 2 I being adjustably carried by block I8. It is therefore apparent that the leveragev of the handle may be varied by arranging shank 2If in any one of its several annular grooves.

The block I6 also receives the stud 22 which has VVa head 23 pivotally connected to the link 24 at its innermostv end 25 and also pivotally connected to The piston 25 fits into the cylinder 28 kby which a liquid, such as cil, may be forced into the hydraulic cylinder I4. The

f hydraulic cylinder I4 is provided with a release valvel 29 which is actuated by the knob 30.

The upper portion of the frame I2 is provided withra cylindrical guidey 3 I, which receives the depending shank or stud 32 depending from the last or anvil member 33 shaped complementally to a portion of a shoe.` The lower end 34 of the stud 32 rests upon and contacts with the top of the piston I5 of the hydraulic cylinder I4.

.The -upper portion of the anvil member is shaped to the front portion of the shoe which is to bereceived or placed thereupon. The top of the anvilor last member 33 has a projecting ledge or lip 35 `which'is shaped to receive the replaceable pressure plates 36, and the type more fully shown in Figs. 3 to 12. These plates are each correctlypositioned upon the ledge 35 by the vertically depending lip 31 at their front ends and by the curved downturned portion 38 at their rear ends, curved portion 38 having a depending terminal fitting along the rear slightly inclined vertical end face of ledge 35 of the anvil and cooperating with thel latter to prevent longitudinal displacement of a respective pressure plate placed on the; anvil.

The-upper part of the structure I2 is provided withan upstanding extension 39, the upper portion of which receives the pivot rod or pin 40 formingv aI pivotal connection with the downturnedv end 4I A'ofthe elongated head member 42.

The other end of the head is similarly provided with a pinor rod 43 which pivotally or swingably Y connects the depending link or latch 44 with the Fig. 2 is a side sectional view'upon,V the line head 42, the laterally extending handle carried by the latch servingto enable manipulation of said latch 44. The structure or frame I2 is provided with 'the outward extension or lip 46 overhanging a side thereof, which lip cooperates and interlocks with the concavity 41 in the latch 44 to hold the same firmly in position. For purposes of speciiication, latch 44 may be considered asl a socketorfhousing for removably enclosing overhanging lip 46. The contacting face of the head 48 is provided with'the replaceable pressure resisting lplate 48, which may be readily removed and replaced by loosening the screws 50.

To'lock the anvil member in clamped position, the depending shank32 of the anvil member 33 is provided' Withatapered slot 5I which cooperates with'. the end of the threaded shank 52 having the adjusting wheel or knob 53. The end 54 of the shank 52 may be firmly clamped against the verticallyinclined face of the tapered slot 5I by turning of the knob 53 to prevent movement of the anvil member when it has gripped the sole of the shoe against the complementary clamping plate 49 contacting head 42.
