Automatic bottom roughing machine

Claim 2

Apparatus for use in operating on marginal portions of shoe bottoms comprising a shoe support, tool supporting means, means for effecting relative movement between the shoe support and the tool supporting means in one direction whereby, when the apparatus is in use, a tool supported by the tool supporting means is caused to operate progressively along a marginal portion of a shoe supported by the shoe support, and thereafter in an opposite direction, and means whereby such relative movement in the opposite direction can be arrested, the arresting means being adjustable to operate relative to the position of the end portion of the shoe nearer to the tool supporting means.

Claim 3

Apparatus according to claim 1 further including means for supporting a template, and sensing means for cooperating with the template supported by a template supporting means, the template supporting means cooperative with the shoe support and being operatively connected to the tool supporting means to control the tool supporting means so that a tool supported thereby follows a path corresponding to the shape of a marginal portion of the bottom of a shoe supported by the shoe support and operates progressively along said marginal portion.

Claim 4

Apparatus according to claim 2 wherein the arresting means comprises a switch arrangement and an actuator arrangement therefor which are positioned relative to one another according to the size and style of a template supported by the template supporting means.

Claim 5

Apparatus according to claim 3 wherein the actuator arrangement comprises an actuator member positioned on the shoe support in a position determined by the style and size of a template supported by the template supporting means.

Claim 6

Apparatus according to claim 3 wherein the switch arrangement comprises a control valve by which is controlled the means for effecting relative movement between the shoe support and the tool supporting means.

Claim 7

Apparatus according to claim 2 including decelerating means whereby relative movement in the opposite direction between the shoe support and the tool supporting means can be decelerated prior to being arrested.

Claim 8

Apparatus according to claim 6 wherein the decelerating means comprises a switch arrangement and an actuator arrangement therefor which are positioned relative to one another according to the style and size of a template supported by the template supporting means.

Claim 9

Apparatus according to claim 7 wherein the actuator arrangement comprises a actuator member positioned on the shoe support in a position determined by the size and style of a template supported by the template supporting means.

Claim 10

Apparatus according to claim 6 wherein the means for effecting relative movement between the shoe support and the tool supporting means is fluid pressure operated and a switch arrangement for the decelerating means is included which comprises a restrictor valve by which the flow of pressure fluid to said fluid pressure operated means is restricted.

Claim 11

Apparatus according to claim 2 wherein the shoe support includes two devices by which opposite end portions of a shoe can be supported, and the one of said devices by which the end portion, nearer to the tool supporting means of a shoe is supported, is mounted for adjusting movement relative to the other of said devices, said one device being positioned in the shoe support according to the size and style of a template supported by the template supporting means.

Claim 12

Apparatus according to claim 10 wherein the shoe support is movable relative to the tool supporting means along a path extending generally lengthwise of a shoe supported by the shoe support.

Claim 13

Apparatus suitable for use in operating on marginal portions of shoe bottoms comprising a shoe support, tool supportIng means, means cooperating with the shoe support for supporting a template selected according to the style of shoe to be operated upon, sensing means operatively connected to the tool supporting means for cooperating with a template supported by the template supporting means, and means for effecting movement of the shoe support and the cooperating template supporting means relative to the tool supporting means, relative to the sensing means, in one direction, along a path extending generally lengthwise of a shoe supported by the shoe support whereby a tool supported by the tool supporting means operates progressively along a marginal portion of the bottom of a shoe supported by the shoe support, and for thereafter moving said shoe support in an opposite direction, and means for arresting movement of the shoe support moving in said opposite direction at a point in the path selectable according to the size and style of a template supported by the template supporting means.

Claim 14

Apparatus suitable for use in operating on marginal portions of shoe bottoms comprising a shoe support, tool supportIng means, means cooperating with the shoe support for supporting a template selected according to the style of shoe to be operated upon, sensing means operatively connected to the tool supporting means for cooperating with a template supported by the template supporting means, and means for effecting movement of the shoe support and the cooperating template supporting means relative to the tool supporting means, relative to the sensing means, in one direction, along a path extending generally lengthwise of a shoe supported by the shoe support whereby a tool supported by the tool supporting means operates progressively along a marginal portion of the bottom of a shoe supported by the shoe support, and for thereafter moving said shoe support in an opposite direction, and means for arresting movement of the shoe support moving in said opposite direction at a point in the path selectable according to the size and style of a template supported by the template supporting means.

Claim 15

Apparatus according to claim 2 wherein a pair of tools supported by the tool supporting means are caused to operate progressively along opposite marginal portions of the bottom of a shoe supported by the shoe support.

Claim 16

Apparatus according to claim 13 wherein the tools are rotary wire brushes, supported by the tool supporting means.
