Abstract: Holder consists of a base connected to fences at each end. Legs, one at each side of the base, are attached to the base at the movable fence end. Deploying legs positions the base in an acceptable book reading angle with the movable fence upward. Books, hard or soft cover, are held in place on the base by the inside edges of page tab assemblies which are spring loaded to the fences through elongated slots. Tabs are adjusted to hold down pages of a book by moving them perpendicularity and/or side to side over each side of an opened book's pages. Further tab adjustments needed to obtain a clear field of reading vision is obtain by rotating the tab page retainers. Page turning is accomplished without further adjustment or movement of the tab assembly.

Abstract: A structure for mounting an armature assembly to a frame of an electromagnetic relay is disclosed. Various construction details are developed which disclose a shaped bearing disposed on a frame and an armature assembly having a complementary bearing surface. The engagement of the shaped bearing and bearing surface permits pivoting of the armature assembly while providing capture of the armature assembly to the frame. In one embodiment, an electromagnetic relay (70) includes a frame (72) having a pair of spherical bearings (88, 90) and an armature assembly (78) having a pair of spherical recesses (102, 104) formed and positioned to complement the spherical bearings.
