Abstract This invention consists of a metal casting mounted on a grinder, the casting is adapted to hold air-operated mechanism in the form of a longitudinally-disposed piston and rod adapted to provide support for a carbide throw-away insert by means of other mechanism, as will hereinafter be described. This air piston and its associated parts is located in the left-hand portion of the aforesaid casting. The casting is provided with an opening between its left-hand portion and its right-hand portion for the reception of the carbide throw-away insert which is held in place by means of an anvil on the end of structure of the internal mechanism of the device in which the aforesaid piston rod is located. The aforesaid carbide throw-away insert is also held in place for grinding by means of mechanism on the end of a locator clamp rod that is longitudinally disposed in the right-hand portion of the aforesaid metal casting. This invention is activated to firmly hold the often-mentioned carbide throw-away insert by means of both air and oil systems, as will hereinafter be described in this specification.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
Apparatus for grinding throw-away inserts comprising: a. a structural frame having a longitudinal principal axis; b. an anvil element stationarily mounted on said frame on said longitudinal axis and having a face concentric on and transverse to said axis conditioned to abut one surface of said inserts; c. a plunger element slidably mounted on said longitudinal axis toward said anvil element and having a face conditioned to abut a surface of said inserts opposite said one surface; and d. a locator element slidably mounted on said longitudinal axis, said locator forming a housing surrounding said anvil and having an opening larger than and concentric with said anvil element and adapted to hold said inserts concentric on said axis, said opening having walls longitudinally slanting toward said anvil element, said insert being mounted on said locator at said opening, said plunger element being forced against said insert toward said anvil, and means for withdrawing said locator over said anvil when said insert is concentrically mounted on said axis between said plunger element and said anvil element.
Claim 2
Dependent Claim
175 words
Apparatus for grinding throw-away inserts comprising: a. a structural frame having a longitudinal principal axis; b. an anvil element stationarily mounted on said frame on said longitudinal axis and having a face concentric on and transverse to said axis conditioned to abut one surface of said inserts; c. a plunger element slidably mounted on said longitudinal axis toward said anvil element and having a face conditioned to abut a surface of said inserts opposite said one surface; and d. a locator element slidably mounted on said longitudinal axis, said locator forming a housing surrounding said anvil and having an opening larger than and concentric with said anvil element and adapted to hold said inserts concentric on said axis, said opening having walls longitudinally slanting toward said anvil element, said insert being mounted on said locator at said opening, said plunger element being forced against said insert toward said anvil, and means for withdrawing said locator over said anvil when said insert is concentrically mounted on said axis between said plunger element and said anvil element.
Claim 3
Dependent Claim
40 words
Apparatus as decribed in claim 1 wherein said housing of said locator element has a lower ledge extending beyond all other walls of said housing, said ledge maintaining inserts in position for said piston element properly to abut said insert.
Claim 4
Dependent Claim
87 words
Apparatus as described in claim 1 wherein said means for withdrawing said locator includes: a. a shaft located on said axis on the side of said anvil opposite said plunger element; b. means for coupling said shaft to said housing; and c. motive means for withdrawing said shaft from said anvil, whereby said opening is positioned between said plunger and said anvil when inserts are positioned therein, and said opening is withdrawn around and behind said anvil when inserts are locked between said anvil and said plunger.
Claim 5
Dependent Claim
26 words
Apparatus as described in claim 1 wherein said slanting walls of said housing are centered about said axis on all transverse cross sections of said housing.
