Description

SPECIFICATION Sole Attaching Press with Abutment for Pressing Rear of Heel This invention is concerned with a sole attaching press for use in attaching soles to lasted shoes by means of adhesive comprising a support for a shoe with a sole positioned thereon, and pressure applying means operable to apply pressure between the shoe and the support to attach the sole to the shoe, the support comprising pads which are conformable to the shape of the bottom of the shoe over the to and waist regions thereof, a pad arranged to apply pressure to a tread surface of a heel of the shoe, moving means operable to move said pad into engagement with said tread surface, and an abutment arranged to apply pressure to the rear of a heel of the shoe.The abutment is mounted on a lever which is pivotal about an axle which extends transversely of the shoe to bring the abutment into engagement with the rear of the heel.

In known sole attaching presses of the abovedescribed type, the pad which is arranged to apply pressure to the tread surface is movable into engagement by moving means in the form of a piston and cylinder assembly. A further piston and cylinder assembly is arranged to pivot the lever about the axle to bring the abutment into engagement with the rear of the heel. The provision of two piston and cylinder assemblies increases the cost of the press.

This invention has the object of removing the necessity for a separate piston and cylinder assembly for bringing the abutment into engagement.

The invention provides a sole attaching press for use in attaching soles to lasted shoes by means of adhesive comprising a support for a shoe with a sole positioned thereon, and pressure applying means operable to apply pressure between the shoe and the support to attach the sole to the shoe, the support comprising pads which are conformable to the shape of the bottom shoe over the toe and waist regions theredf, a pad arranged to apply pressure to a tread surface of a heel of the shoe, moving means operable to move said pad into engagement with said tread surface, and an abutment arranged to apply pressure to the rear of a heel of the shoe, wherein operation of the moving means for the pad which is arranged to apply pressure to a tread surface of a heel of the shoe is also effective to move the abutment into engagement with the rear of the heel.

Advantageously, the abutment is mounted on a lever which is pivotal about an axle which extends transversely of the shoe to bring the abutment into engagement with the rear of the heel and the moving means carries a pin which engages in an inclined slot in the lever, the slot being so inclined that, as the moving means moves the pin, the lever is caused to pivot about the axle.

Conveniently, the pin extends transversely across a fork extending from the moving means and the lever is movable in the fork; this arrangement enables the pin to withstand considerable force.

Since the press may be required to operate on shoes which do not require the use of the abutment, the pin is optionally removable to allow the press to operate without using said abutment.

An example of the embodiment of the invention will now be described in detail with reference to the accompanying drawings.

In the drawings: Figure 1 is a side elevation view with parts broken away of a support of a sole attaching press operating on a ladies' shoe; and Figure 2 is a view similar to Figure 1 showing operation on a men's shoe.

Figure 1 shows a small ladies' shoe 1 on a last 19 in broken line and a large ladies' shoe 2 on a last 1 8 in solid line and Figure 2 shows a men's shoe 50. The shoes 1 and 2 have a high heel 3 and the shoe 50 has a.heel 52. The shoe is supported in front of its heel 3 or 52 by a pad 4 of a support of the press and at its toe on a pad 5 mounted on an assembly 7 of the support. The sole 1 3 or 51 of the shoe is positioned on the shoe with a layer of adhesive between the sole and the shoe. The pad 4 is adjustable in height by a bolt 6 and the assembly 7 is pivoted on the axle 9 extending transversely of the shoe. Beyond the toe end of the shoe, the assembly 7 is supported by a plunger 10 which rests on a spring 11 adjustable by an adjusting screw 12.

The press also comprises two presser members 14 and 15 arranged to engage respectively a heel portion and a toe portion of a lasted shoe on the support. The presser member 1 5 is adjustable longitudinally of the shoe (e.g. to the position shown as 1 5') and carries a pad 16 (16') and the presser member 14 carries a foot 17.

After the shoe has been positioned on the support, the support and the presser members 14 and 1 5 are moved together to apply pressure between the shoe and the sole. As this occurs, the assembly 7 pivots about the axle 9 to conform the pad 5 to the shape of the bottom 8 of the shoe.

When the support and the presser members have been brought together so that the shoe is under pressure, hydraulic fluid under pressure is applied to cylinders 28 and 29 in the waist region of the support which raise pistons 24 to 27 carrying pads 20 to 23 so that the pads press on the bottom 8 in the waist region of the shoe. The pads 20 to 23 are guided by guides 30 and 31 in their upwards movement.

As the pistons 24 to 27 move upwards, they release a lever 32 pivoted on an axle 33 so that a spring 34 raises the lever 32 and brings a rack 35 of the lever 32 into meshing engagement with a rack 36 on an arm 37 of the assembly 7 thereby locking the pad 5 in its conformed position. The pad 5 is supported on the assembly 7 at the rear thereof on a wedge-shaped underlay 38 which allows the pad 5 to tiit slightly on the assembly 7.

When the pad 5 has been locked in position and the pads 20 to 23 are in engagement, a higher attaching pressure is applied between the shoe and the support.

The support also comprises a cylinder 46 assembied with a piston 45 to provide moving means operable to move a pad 53 on a carrier 44 carried by the piston 45 into engagement with the tread surface of the heel 52. The pad 53 is arranged to apply pressure to the tread surface of the heel 52. A lever 42 is pivotal on an axle 43 of the shoe support which extends transversely of the shoe. The lever 42 carries an abutment 41 in the form of a pad on a support 42 which is movable along the lever 42. The abutment 41 is arranged to apply pressure to the rear of a heel 3 of the shoe when brought into engagement therewith by pivotal movement of the lever 42.

The piston and cylinder assembly 45, 46 is effective not only to move the pad 53 but also to cause the lever 42 to pivot. To this end, the carrier 44 carries a pin 49 which engages in an inclined slot 48 in the lever 42. The slot 48 is so inclined that, as the pin 49 is moved upwards, the lever 42 is caused to pivot about the axle 43 to bring the abutment 41 into engagement.

The pin 49 extends transversely across a fork 47 of the carrier 44, being received in holes therein. The fork 47 extends on both sides of the lever 42 so that the lever 42 is movable in the fork 47. The pin 49 can be removed from the holes in the fork 47 to allow the press to operate without using the abutment 41 in which case the lever 42 rests against a stop 54 (as shown in Figure 2). If desired, the stop 54 can be in the form of a microswitch which can be used to control the pressure applied by the press.

When a ladies' shoe with a high heel 3 is to be pressed, as shown in Figure 1, it is not necessary to press on the tread surface of the heel 3 and so the cushion 53 is not placed on the carrier 44.

Thus, the press operates with the piston and cylinder assembly 45, 46 only causing pressure by the abutment 41. However, when a men's shoe with a low heel 52 is to be pressed, as shown in Figure 1, it is not necessary to press on the rear of the heel 52 and so the pin 49 is removed and the press operates with the piston and cylinder assembly 45, 46 only causing pressure by the pad 53.

Because of the dual function of the piston and cylinder assembly 45, 46, the press is rendered less expensive.
