Silkscreen frame mounting assembly for press

In combination:

• a stencil screen printing press including a screen frame support having spaced support members,
• a mounting assembly for removably mounting a stencil screen frame on said screen frame support between said support members,
• said mounting assembly comprising an open rectangular carrier frame having sidewalls along the edges of the carrier frame substantially normal to the plane of the carrier frame and flanges projecting inwardly from sa1d sidewalls along the sidewall edges at the opposite side of said carrier frame and disposed in a common plane generally parallel to said plane of the carrier frame, said opposite side of said carrier frame having an opening bounded circumferentially by said flanges, said carrier frame being adapted to receive said screen frame in a position wherein said screen frame rests on said flanges, screws threaded in said carrier frame sidewalls with their axes substantially parallel to said plane of the carrier frame for engaging the edges of a screen frame positioned in the carrier frame to releasibly secure the screen frame in the carrier frame, and means mounting said carrier frame on said screen frame support of the printing comprising mounting brackets rigidly joined to two opposite sidewalls of said carrier frame including arms extending outwardly from said opposite sidewalls and over said support member in a common plane substantially parallel to said plane of said carrier frame flanges and offset from the latter plane toward one side of said carrier frame, and means for securing said bracket arms to said support members.

In combination:

• a stencil screen printing press including a screen frame support,
• a mounting assembly for removably mounting a stencil screen frame on said screen frame support including mounting means attached to said screen frame support for receiving a screen frame, and readily accessible, easily releasible fastening means for releasibly securing a stencil screen frame to said mounting means,
• said mounting means comprising a carrier frame for removably recieving said screen frame, and attachment means attaching said carrier frame to said screen frame support,
• said fastening means being mounted on said carrier frame,
• said carrier frame being an open rectangular frame having sidewalls transverse to the plane of the carrier frame for confining the screen frame edgewise, and flanges projecting inwardly from said sidewalls generally parallel to said plane for supporting the screen frame in the carrier frame,
• said fastening means comprising fasteners threaded in said carrier frame sidewalls for engagement with the screen frame in the carrier frame,
• said attachment means comprising mounting brackets on said carrier frame, and means securing said mounting brackets to said screen frame support,
• said printing press being a cylinder screen printing press including a cylinder located at one side of said carrier frame with its axis generally parallel to the plane of said carrier frame,
• said carrier frame flanges being located along the edges of said carrier frame sidewalls adjacent said cylinder, whereby said carrier frame supports a stencil screen frame with its stencil screen in a plane substantially tangent to said cylinder, and
• said screen frame support comprising a carriage movable back and forth in the edgewise direction of said carrier frame transverse to said cylinder and parallel to the plane of the carrier frame.

A stencil screen frame and mounting assembly to be mounted on the screen frame support of a stencil screen printing bress between spaced support members of said screen frame support, comprising:

• a rectangular screen frame having a stencil screen spanning one side of the screen frame,
• an open rectangular carrier frame to be positioned between said support members of said printing press of receiving said screen frame through one side of the carrier frame, said carrier frame having sidewalls along the edges of the carrier frame substantially normal to the plane of the carrier frame and flanges projecting inwardly from said sidewalls along the sidewall edges at the opposite side of said carrier frame and disposed in a common plane generally parallel to said plane of the carrier frame, said opposite side of said carrier frame having an opening bounded circumferentially by said flanges,
• said carrier frame receiving said screen frame in a position wherein said screen frame rests on said flanges with said stencil screen extending across said carrier frame side opening,
• screws threaded in said carrier frame sidewalls with their axes substantially parallel to said plane of the carrier frame and engaging said screen frame positioned in the carrier frame to releasibly secure the screen frame in the carrier frame, and
• mounting brackets rigidly joined to two opposite side walls of said carrier frame for mounting said carrier frame on said screen frame support of the printing press, said mounting brackets including arms extending outwardly from said opposite sidewalls in opposite edgewise directions of said carrier frame and in a common plane substantially parallel to said plane of said carrier frame flanges and offset from the latter plane toward said one side of said carrier frame for engagement over said screen frame support members of said printing press.

In combination:

• a stencil screen printing press including a screen frame support having spaced support members,
• a mounting assembly for removably mounting a stencil screen frame on said screen frame support,
• said mounting assembly comprising an open rectangular carrier frame to be positioned between said support members, said carrier frame having sidewalls along the edges of the carrier frame substantially normal to the plane of the carrier frame and flanges projecting inwardly from sa1d sidewalls along the sidewall edges at the opposite side of said carrier frame and disposed in a common plane generally parallel to said plane of the carrier frame, said opposite side of said carrier frame having an opening bounded circumferentially by said flanges, said carrier frame being adapted to receive said screen frame in a position wherein said screen frame rests on said flanges, screws threaded in said carrier frame sidewalls with their axes substantially parallel to said plane of the carrier frame for engaging the edges of a screen frame positioned in the carrier frame to releasibly secure the screen frame in the carrier frame, and mounting brackets rigidly joined to two opposite sidewalls of said carrier frame mounting said carrier frame on said screen frame support of the printing press, said mounting brackets including arms extending outwardly from said opposite sidewalls in opposite edgewise directions of said carrier frame and in a common plane substantially parallel to said plane of said carrier frame flanges and offset from the latter plane toward said one side of said carrier frame for engagement over said screen frame support members of said printing press.
