Claim 1
Independent Claim
213 words
A machine for forming a formation in a sheet of material, comprising: a. a frame means having a stationary portion, a vertically movable portion and a means to move said vertically movable portion, b. powered means mounted with said stationary portion of said frame means and said vertically movable portion thereof to move a sheet of material through said frame means between said stationary portion and said movable portion, c. means mounted with said movable portion to removably mount a cutting tool said means to removably mount a cutting tool having an adjustable mounting means constructed and adapted to adjust the position of said cutting tool vertically relative to said vertically movable frame portion, d. a cutting tool having a mounting means to removably mount said cutting tool with said means to mount a cutting tool, said cutting tool having when mounted a downwardly extending blade to in use cut a formation in a sheet of material as said sheet of material is moved through said machine by said means to move a sheet of material, and e. said cutting tool mounting means has a latch means with a movable plunger constructed and adapted to in use mount said cutting tool in a fixed position with said means to mount a cutting tool.
Claim 2
Dependent Claim
213 words
A machine for forming a formation in a sheet of material, comprising: a. a frame means having a stationary portion, a vertically movable portion and a means to move said vertically movable portion, b. powered means mounted with said stationary portion of said frame means and said vertically movable portion thereof to move a sheet of material through said frame means between said stationary portion and said movable portion, c. means mounted with said movable portion to removably mount a cutting tool said means to removably mount a cutting tool having an adjustable mounting means constructed and adapted to adjust the position of said cutting tool vertically relative to said vertically movable frame portion, d. a cutting tool having a mounting means to removably mount said cutting tool with said means to mount a cutting tool, said cutting tool having when mounted a downwardly extending blade to in use cut a formation in a sheet of material as said sheet of material is moved through said machine by said means to move a sheet of material, and e. said cutting tool mounting means has a latch means with a movable plunger constructed and adapted to in use mount said cutting tool in a fixed position with said means to mount a cutting tool.
Claim 3
Dependent Claim
95 words
The machine of claim 1, wherein: a. said vertically movable frame portion is supported from said stationary frame portion on an upper portion of said stationary frame portion, b. said means to move a sheet of material has a plurality of powered rollers rotatably mounted with said stationary frame portion and said vertically movable frame portion, c. said means to removably mount a cutting tool has a cutting tool mounting frame mounted on said vertically movable frame portion, and d. said cutting tool has a mount portion rigidly securable to said cutting tool mounting frame.
Claim 4
Dependent Claim
96 words
The machine of claim 2, wherein: a. said frame means is elongated with said vertically movable frame portion mounted on opposite end portions thereof by said means to move said vertically movable frame portion, b. said frame means has an inlet table portion on one side of said stationary frame portion for guiding sheet material into said machine and an outlet table portion on the opposite side of said stationary frame portion for guiding sheet material from said machine, and c. said plurality of powered rollers each have a resilient covering to grip said sheet material.
Claim 5
Dependent Claim
120 words
The machine of claim 3, wherein: a. said plurality of powered rollers has two pairs of generally opposed rollers on opposed side portions of said frame, one roller of each of saiD pairs mounted with stationary frame portion and one mounted with said vertically movable frame portion, and another roller of said plurality of rollers mounted with said stationary frame portion in opposed relation to said cutting tool, b. said roller mounted in opposed relation to said cutting tool has a resilient covering with an abrasive surface, and c. said means to move said vertically movable frame portion has a screw member rotatably mounted in said stationary frame portion and a threaded member mounted with said vertically movable frame portion.
Claim 6
Dependent Claim
167 words
The machine of claim 4, wherein: a. said cutting tool mounting frame has elongated members extending substantially the length of said vertically movable frame portion, said cutting tool vertically adjustable mounting means being on end portions of said cutting tool mounting frame, b. said cutting tool mount portion has a blade support portion mountable on said elongated cutting tool frame members and a cutting tool locking portion engagable with said elongated cutting tool frame members to rigidly secure said cutting tool in a fixed position, c. said means to move a sheet material has a powering means connected by a chain drive means to said plurality of powered rollers to rotate same, and d. said means to move said vertically movable portion has a pair of screw members and threaded members on opposed end portions of said frame means, said screw members being connected by a chain drive means to rotate simultaneously for raising and lowering of said opposite end portions of said vertically movable frame portion.
