Press die clamp

An apparatus for clamping together first and second separable components comprising (a) a support member having an inclined surface and beng adapted to be fixed to the first component, (b) a mounting member fixed to said support member and extending therefrom, and (c) a clamping member slidably mounted on said mounting member and movable between a clamping position and a detached position thereon, said clamping member being adapted to frictionally engage the second component and the support member along said inclined surfae when in said clamping position and to retain the first component adjacent to the second component during thermal expansion of the components while in said clamping position, said clamping member being disengagable from both said first and second components when in said detached position.

An apparatus for clamping together first and second separable components comprising (a) a support member adapted to be fixed to the first component, said member defining an inclined surface and a generally vertical surface, (b) a mounting member fixed to said support member and extending from said vertical surface, (c) a clamping member slidably mounted on said mounting member and movable between a clamping position and a detached position thereon, said clamping member adapted to frictionally engage the second component and frictionally engage said support member along said inclined surface when in said clamping position, wherein said clamping member being adapted to retain the first component adjacent to the second component during thermal expansion of the components while in said clamping position, said clamping member being disengagable from both said first and second components when in said detached position, and (d) a retaining member mounted on said mounting member, said retaining member being connected to said clamping member and adapted to retain said clamping member on said mounting member, said retaining member being freely rotatable with respect to said clamping member.

An apparatus for clamping a heated platen of a frame-type press to a flat surface of an embossing die comprising (a) a support block adapted to be fixed to the platen, said block having an inclined surface and a generally vertical surface, (b) a threaded mounting stud fixed to said support block and extending therefrom, (c) a generally C-shaped clamping member slidably mounted on said mounting stud and movable between a clamping position and a detached position thereon, said clamping member having an upper leg, a lower leg, an aperture and a recess, said lower leg defining a face generally oriented parallel to the flat face of the embossing die, said aperture being adapted to receive said stud, said upper leg being adapted to frictionally engage said inclined surface and said lower leg being adapted to frictionally engage the die when in said clamping position and wherein said clamping member is adapted to retain the die adjacent to the platen during thermal expansion and contraction of the die while in said clamping position, said clamping member being disengagable from both the platen and the die when in said detached position, (d) a retaining nut mounted on said mounting stud, said retaining nut being connected to said clamping member and adapted to retain said clamping member on said mounting stud, said retaining nut being freely rotatable with respect to said clamping member, said nut defining a head portion and a flange portion, and (e) a washer fixed to said clamping member and partially covering said recess, said washer being adapted to retain said flange portion within said recess.

In a clamping system for holding a first component to a lip of a second component, the components having surfaces that extend due to heat expansion, the improvement comprising: (a) a first member adapted to be fixed to the first component, said first member having an inclined surface, (b) means for clamping the first componen, to the second component, said means having a first sloped surface adapted to frictionally engage said inclined surface and a second surface adapted to frictionally engage the lip of the second component while in spaced relation to the extending surfaces thereof.
