In the shaped in cross-section and is applied to the block are formed a series of heel-shaped caviside of a boot or shoe heel opposite the top ties 0, each of which is open at one end.

The follower d is then inserted in the cavity, said follower having recesses to receive the studs L. When the several cavities of the block have been charged, as indicated, it is placed upon the bed of the press and the platen of the press is brought down upon the followers (Z, the result being a compression of the rands, which flattens the wrinkles formed by bending the rands and makes permanent the heel shape imparted to the rands by the walls of the cavities 0'. The pressure being removed, the block is removed from the press and the followers are removed from the cavities. The beds 6 are then lifted from the cavities, thus releasing the completed rands.

As above stated and as shown in Fig. 1, one end of each bed 6 projects sufficiently from the open end of the corresponding cavity 0 to form a handle. These projecting portions or handles of the beds enable said beds to be lifted directly upward from the cavities, so as to remove the completed rands conveniently and expeditiously. Said upward movement of each bed and a rand carried thereby results in the clearing of the fixed stops 6 hereinafter referred to and which form part of the locking means to prevent slipping or lateral movement of the parts.

It will be seen that the described appliance is extremely simple and inexpensive in con struction. Any desired number of said appliances may-be employed simultaneously in a press, the appliances being piled one upon another-between the bed and platen of the press, so that a large number of rands may be pressed simultaneously.

It will be observed that the bottom of the block a is flat. This not only enables the said block to be utilized to form a top plate for a duplicate appliance, but it also insures the resting of the block flat and square upon the platen of a press. The removable members which occupy the cavities of the block a have a total thickness exceeding the depth of the cavities in which they are to be placed, so that the upper surfaces of the followers (Z can project above the upper surface of the block a. The upper surfaces of the followers are all fiat, and therefore they will be equally borne upon by the bottom of the superimposed block when a plurality of the appliances are placed in a press.

We have found that by the use of this appliance we are enabled to materially reduce the cost of forming the complete rands ready for application to boot or shoe heels as compared with the methods and means heretofore employed.

The bed A, which is preferably a thin plate of metal, may be provided with the studs b Z) by suitably cutting the plate to-permit portions of its material to be turned up, forming the studs 6. The opening thus formed in the plate may be utilized to engage fixed stops 6 driven into the block a to prevent the endwise movement of the bed 6 out of the mold cavity. To prevent the endwise movement of the follower d out of the mold-cavity, the bed 6 may be provided with an ear or stop 6 arranged to bear on the outer end of the follower.

Since the fixed stops 5 project upward from the bottoms of the cavities in the block a through openings in the bed-plates b, the said bed-plates are practically locked, so as to be held against lateral movement or a movement that would tend to slip the bed-plates out of the cavities, and the stud Z) rising from the bed-plates and entering recesses in the followers cZ prevents any slipping movement of the followers out of their proper positions in the cavities and on the bed-plates. hen the beds are provided with ears or stops 6 said stops furnish additional locking means to prevent any slipping movement of the followers.

While we have stated that the block a and followers (Z may be made of metal, we do not limit ourselves to this material. The block and followers may be in many cases made of wood.

We claim- 1. A rand-pressing appliance comprising a block having a heel-shaped cavity, a 'heelshaped follower adapted to enter the cavity,

and a removable bed fitting between the fol-- lower and bottom of the cavity, said bed being longer than the cavity so as to project therefrom and form a handle whereby ashaped rand may be lifted from the cavity.

2. A rand-pressing appliance comprising a block having a heel-shaped cavity, a heelshaped follower adapted to enter the cavity, and a removable bed fitting between the follower and bottom of the cavity, said plate being longer than the cavity so as to project therefrom and form a handle whereby'a shaped rand may be lifted from the cavity, the combined thickness of the follower and bed exceeding the depth of the cavity whereby the appliance is adapted to be subjected to the action of a press.

3. A rand-pressing appliance comprisinga I block having a heel-shaped cavity open at one end, a loose heel-shaped bed insertible in the cavity and adapted to project from the open end thereof, and a heel-shaped follower adapted to enter the cavity, said block and bed having locking members to prevent endwise movement of the bed, the bed having also a locking member to prevent endwise movement of the follower.

In testimony whereof we have aflixed our signatures in presence of two witnesses.
