1. A roll holder upon and from which a roll can be mounted and removed with a single hand movement;
- said holder comprising a base, a pair of spaced apart standards fixedly secured to said base and extending normal thereto, a hollow housing on each of said standards arranged in spaced relationship at the same level with respect to one another;
each of said housings opening toward one another, a pair of linearly movable plungers mounted in said hollow-housings;
each of said pair of plungers having a cavity in its inner end and having a long side and a shorter opposite side, a bevelled outer end on each of said plungers joining said long side and said shorter side to which pressure may be applied to move said plungers into said hollow housings, and a spring confined between the inner end of each of said housings and the bottom of each of said cavities in said plungers urging said plungers outwardly for supporting the core of a roll on the long side of each of said plungers;
pressure applied to said bevelled ends of said plungers forcing them into said housings when mounting a roll thereon and when removing a roll therefrom;
each of said housings having an elongated slot therein a hole in the shorter side of each of said plungers extending interiorly thereof and in communication with said slots in said housings, and a pin extending through each of said slots into each of said holes to limit the linear movement of each of said plungers and to prevent rotation thereof.
