Abstract
Abstract The marginal portion of an upper is roughened by rotary brushes while the upper is transported by a carriage having a heel support, and a toe support mounted on an adjustable slide. Adjustment to different sizes of the uppers is carried out by sensing a three dimensional cam which preferably has two parallel cam discs which are both sensed by bridging rollers whose positions are sensed by feeler rollers. The rotary brushes are adjusted in accordance with the positions of the sensing rollers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
Roughening machine for lasted uppers, comprising, in combination, movable carriage means including a heel support for a lasted upper, and a slide movable on said carriage means and having a toe support for said lasted upper, and slanted guide means; three-dimensional cam means driven to rotate about an axis; sensing means including a pair of sensing arms and sensing roller means on said sensing arms cooperating with said cam means; tool means for roughening a marginal portion of said lasted upper, and being controlled by said sensing means; movable mounting means for mounting said sensing means for adjusting movement in the direction of said axis relative to said cam means so that the position of said tool means is adjusted; and follower means guided by said guide means and connected with said mounting means for varying the position of said sensiNg means and tool means depending on the position of said toe support, slide, and guide means.
Claim 2
Dependent Claim
157 words
Roughening machine for lasted uppers, comprising, in combination, movable carriage means including a heel support for a lasted upper, and a slide movable on said carriage means and having a toe support for said lasted upper, and slanted guide means; three-dimensional cam means driven to rotate about an axis; sensing means including a pair of sensing arms and sensing roller means on said sensing arms cooperating with said cam means; tool means for roughening a marginal portion of said lasted upper, and being controlled by said sensing means; movable mounting means for mounting said sensing means for adjusting movement in the direction of said axis relative to said cam means so that the position of said tool means is adjusted; and follower means guided by said guide means and connected with said mounting means for varying the position of said sensiNg means and tool means depending on the position of said toe support, slide, and guide means.
Claim 3
Dependent Claim
50 words
A machine as claimed in claim 1 wherein said cam means includes a shaft and two axially spaced cam discs having differently shaped peripheral cam tracks; and wherein said sensing roller means include bridging roller means engaging both cam tracks and feeler roller means movable along said bridging roller means.
Claim 4
Dependent Claim
32 words
A machine as claimed in claim 2 wherein said bridging roller means are detachably mounted for replacement by a marking tool; and wherein said rotary shaft detachably supports said two cam discs.
Claim 5
Dependent Claim
43 words
A machine as claimed in claim 1 wherein said tool means include a pair of tool arm means, and tools supported on said tool arm means; and a pair of links connecting said sensing arm means with the respective opposite tool arm means.
Claim 6
Dependent Claim
61 words
A machine as claimed in claim 1 comprising actuator means mounted on said slide and on said carriage, respectively, and having an inoperative position and an operative position; switches located along the path of said actuator means and operated by said actuator means in said operative position; and additional tool means actuated by said switches to perform operations on said upper.
Claim 7
Dependent Claim
31 words
A machine as claimed in claim 1 wherein said tool means include rotary roughening brushes, and feeler fingers turnable about axes perpendicular to the axes of said rotary roughening brushes, respectively.
Claim 8
Dependent Claim
52 words
A machine as claimed in claim 1 comprising a plurality of carriages; and an endless chain for transporting said carriages with lasted uppers; arresting means for arresting said sensing means in adjusted positions; a limit switch operated by each carriage; and means operated by each limit switch to release said arresting means.
Claim 9
Dependent Claim
42 words
A machine as claimed in claim 1 wherein said guide means includes a slot slanted to vertical and horizontal directions; and wherein said mounting means include a slanted guide surface engaged by said follower means, said follower means including a follower roller.
