Method of upholstering a couch and edge wire spring stabilizing clamp

An edge wire clamp adapted for mounting upon and along the front rail of a hollow frame of a couch or chair to be upholstered, with the frame having a webbing thereon, a series of longitudinally extending rows of spaced coil springs within the frame mounted upon the webbing parallel to the rail and projecting above the frame, and with the frame also including a longitudinal edge wire extending tangent to the top coils of the row of springs adjacent the rail and connected thereto thereby securing the row of springs together;

• said edge wire clamp comprising an upright first support of channel shape configuration, said first support having a vertically extending web provided with inner and outer flat surfaces and a pair of perpendicular side flanges extending away from said surfaces, said outer surfaces adapted to bear against the exterior of the rail;
• a manually adjustable gripping member on said first support adapted to operatively engage the rail for adjustably securing said first support thereto;
• a grip support of channel shape configuration mounted on said first support and secured thereto;
• said manually adjustable gripping means including a manually rotatable screw threaded through said grip support and having a leading end movable toward and away from said outer surface on said first support;
• a grip mounted upon the leading end of said rotatable screw adapted to engage the rail;
• an edge wire retainer block having a rectangular opening therein through which said first support extends, said opening having a surface engageable with the outer surface of said first support, said block being slidably mounted upon said first support for selective adjustment thereon;
• a gripping means on said retainer block including a friction hand operated screw threaded through said block and extending into said opening and engaging the inner surface of said first support, said hand operated screw being adapted to thereby operatively secure said block at a predetermined height on said first support;
• an edge wire retaining means including a pair of laterally spaced pins joined to and depending from said retainer block, said pins being spaced laterally from the inner surface of said first support and adatped to secure the edge wire relative to said first support;
• and a stop bar extending through said side flanges at the upper end of said channel shape first support and projecting from opposite sides thereof, said stop bar limiting upward adjustments of said retainer block upon said first support;
• said edge wire clamp adapted to facilitate locating and stabilizing the row of springs adjacent the rail and for maintaining the outer edges of the top coils of the row of springs in a straight line at a uniform height outwardly of the rail, to facilitate the individual tying of the springs of the other row of springs together, to the row of springs adjacent the rail and to the frame.
