Abstract
Abstract A hollow horizontal support of inverted U-shaped cross-section has a base plate secured transversely thereto at its rearward end, and also has parallel side walls interconnected by a top wall, and further has a forward end wall with a downwardly-extending portion serving as a fixed article-gripping jaw. Slidably mounted in a hole in this end wall and provided with a movable article-gripping jaw projecting downward therefrom is a spring-pressed plunger, the forward end of which projects forwardly through the forward end wall in a push-button portion, the rearward end of which slidably engages the side wall of a hole in the front wall of a hollow rear spring abutment and plunger guide member of up-ended scoop-shaped form disposed in the interior of the U-shaped support and held therein by integral transverse lugs projecting laterally therefrom and fitting into notches in step portions of the opposite side walls of the support. A compression coil spring encircling the reduced-diameter rearward portion of the plunger between the movable article-gripping jaw and the fixed spring abutment member urges the movable article-gripping jaw into gripping engagement with an article inserted between it and the fixed article-gripping jaw.

A spring-pressed-plunger article holder adapted to be mounted upon an upright wall, said article holder comprising an elongated hollow open-bottomed support having a top wall and laterally-spaced side walls and a forward end wall, an article-holder-mounting base plate secured to the rearward end of said support, said walls and said base plate cooperatively defining an elongated open-bottomed plunger-housing cavity in said support, said forward end wall having a forward plunger guide hole therethrough and having a fixed article-gripping jaw extending downward therefrom, a combined rearward spring abutment and plunger guide member disposed in said cavity in direct engagement with said base plate, said combined abutment and guide member having a rearward plunger guide hole therethrough coaxial with said forward guide hole, means for securing said rearward spring abutment and plunger guide member within said support cavity with its rearward plunger guide hole in alignment with said forward plunger guide hole, an elongated plunger slidably mounted in said guide holes and having a push-button portion projecting forwardly from said forward end wall, said plunger also having a movable article-gripping jaw depending transversely therefrom in parallel relationship to said fixed article-gripping jaw and movable unitarily with said plunger, and a spring member disposed between said movable jaw and said spring abutment and plunger guide member and adapted to urge said movable article-gripping jaw toward said fixed article-gripping jaw into gripping engagement with an article disposed therebetween, said combined rearward spring abutment and plunger guide member being of up-ended scoop shaped construction with a front wall, a pair of side walls disposed in spaced parallel relationship, and a bottom wall interconnecting the lower ends of said front wall and side walls, said plunger being loosely mounted in said rearward guide hole whereby to greatly facilitate tilting and sliding of said abutment and guide member relatively to said plunger during assembly, said side walls of said abutment and guide member having rounded upper rearward corners adapted to rockably and slidably engage said base plate during tiltable insertion of said member into said cavity.
