US3572841A — Material pickup for groove cutters

Claim 1

Independent Claim 247 words

In a cutting machine having a rotatable cutter, apparatus for removing particles of material produced by the cutter during cutting, said apparatus including: means for supplying said cutter with a cooling liquid; structure disposed to contain within limited bounds said liquid and said material being centrifugally projected by the cutter; collector means disposed to receive the liquid and the material from said structure, the latter including an open bottom hood overlying the cutter in diametrically opposed relationship to a surface being cut; said hood having a front, surface-engaging, flexible apron spaced radially outwardly of said periphery of the cutter, and an outlet above the apron; said collector means including a first, open top container at the rear of said hood underlying the latter radially outwardly of the periphery of said cutter; and a second container disposed to receive liquid and material projected through said outlet by the cutter; said cutter having a member on each side respectively thereof, rotatable with the cutter and provided with an annular face spaced radially inwardly of said periphery of the cutter; and means for stripping the cutter and said faces of liquid and material tending to rotate with the cutter and the members around the axis of rotation thereof; certain of said stripping means being disposed to direct the stripped liquid and material into the first container through the open top of the latter, another of said stripping means being disposed to direct the stripped liquid and material through said outlet.

Claim 2

Dependent Claim 247 words

In a cutting machine having a rotatable cutter, apparatus for removing particles of material produced by the cutter during cutting, said apparatus including: means for supplying said cutter with a cooling liquid; structure disposed to contain within limited bounds said liquid and said material being centrifugally projected by the cutter; collector means disposed to receive the liquid and the material from said structure, the latter including an open bottom hood overlying the cutter in diametrically opposed relationship to a surface being cut; said hood having a front, surface-engaging, flexible apron spaced radially outwardly of said periphery of the cutter, and an outlet above the apron; said collector means including a first, open top container at the rear of said hood underlying the latter radially outwardly of the periphery of said cutter; and a second container disposed to receive liquid and material projected through said outlet by the cutter; said cutter having a member on each side respectively thereof, rotatable with the cutter and provided with an annular face spaced radially inwardly of said periphery of the cutter; and means for stripping the cutter and said faces of liquid and material tending to rotate with the cutter and the members around the axis of rotation thereof; certain of said stripping means being disposed to direct the stripped liquid and material into the first container through the open top of the latter, another of said stripping means being disposed to direct the stripped liquid and material through said outlet.

Claim 3

Dependent Claim 54 words

In a cutting machine as claimed in claim 1, said hood having a downwardly facing, rear, terminal edge spaced above said surface and radially outwardly of said periphery of the cutter; said first container depending from said edge with its open top between said periphery of the cutter and said edge of the hood.

Claim 4

Dependent Claim 149 words

In a machine for cutting grooves: a rotatable cutting disc having opposed sides and a peripheral cutting edge; means for supplying said disc with a cooling liquid during removal of material from a surface being grooved by the disc; structure disposed to contain within limited bounds said liquid and said material being centrifugally projected by the rotating disc; collector means adjacent said disc and said structure for receiving the liquid and the material; and means for stripping the disc of liquid and material tending to rotate with the disc around its axis of rotation, including a stripper plate in said structure having a clearance notch receiving said disc to position the plate in closely spaced relationship to the peripheral edge and sides of the disc to effect removal of liquid and material therefrom; said stripping means being disposed to direct the removed liquid and material into said collector means.

Claim 5

Dependent Claim 149 words

In a machine for cutting grooves: a rotatable cutting disc having opposed sides and a peripheral cutting edge; means for supplying said disc with a cooling liquid during removal of material from a surface being grooved by the disc; structure disposed to contain within limited bounds said liquid and said material being centrifugally projected by the rotating disc; collector means adjacent said disc and said structure for receiving the liquid and the material; and means for stripping the disc of liquid and material tending to rotate with the disc around its axis of rotation, including a stripper plate in said structure having a clearance notch receiving said disc to position the plate in closely spaced relationship to the peripheral edge and sides of the disc to effect removal of liquid and material therefrom; said stripping means being disposed to direct the removed liquid and material into said collector means.

Claim 6

Dependent Claim 84 words

In a machine as claimed in claim 3, said structure including said structure including an open bottom hood overlying the disc in diametrically opposed relationship to said surface and having portions disposed forwardly and rearwardly with respect to the direction of rotation of the disc; a said collector means including an open top container at the rear of said hood underlying the latter radially outwardly of the peripheral edge of the disc and disposed to receive liquid and material revolving completely through the hood.

Claim 7

Dependent Claim 51 words

In a machine as claimed in claim 3, there being a member on each side respectively of said disc, rotaTable therewith and provided with an annular, circumferential face spaced radially inwardly of said peripheral edge of the disc; said plate extending inwardly to terminations proximal to the faces of the members.

Claim 8

Dependent Claim 24 words

In a machine as claimed in claim 5, portions of said plate adjacent said faces of the members being disposed in tangential relationship thereto.

Claim 9

Dependent Claim 71 words

In a machine as claimed in claim 3, there being a series of said discs axially spaced from one another and rotatable as a unit; and members between the discs rotatable therewith and provided with annular, circumferential faces spaced radially inwardly of the peripheral edges of the discs; said plate having a series of said notches receiving corresponding discs, and extending inwardly to terminations proximal to said faces of the members.
