Abstract: A mounting bracket for releasably mounting an article such as a sign or picture frame to a substantially flat surface such as a wall. The bracket has an adhesive disc securely attached to one side of the bracket and the opposite side of the adhesive disc has a releasable adhesive face for attaching to the wall. A tool inserted into the mounting bracket applies a rotative force to the mounting bracket for applying a shear force to the releasable adhesive face which causes the adhesive face to release from the wall. The mounting bracket is releasably mounted to a sign, which allows easy installation and removal of the sign from the wall.

Abstract: A manually operated ink stamp having a base with an open bottom and an aperture in the top wall. A box-like frame having an open bottom is disposed within the base and has a lower edge. A sleeve is connected to the upper portion of the frame and extends upwardly through the aperture in the base and is connected to a handle. The handle and frame are biased upwardly with respect to the base by a compression spring that is interposed between the handle and the base. Located within the frame is a die holder that carries a printing die impregnated with ink, and the lower surface of the die projects downwardly beyond the lower edge of the frame. A threaded adjustment is provided for adjusting the vertical position of the die holder and die with respect to the frame.

Abstract: The present invention is directed to an improved clip and supporting rack therefor. The clip is constructed with rigid outwardly diverging arms to eliminate the need to force the stamp handle through a throat, and does not require spring loading. Furthermore, the clip easily accommodates stamps having handles of numerous sizes and shapes. One embodiment of supporting rack is free standing and provides circular clip supports forming storage bins for small items such as paper clips and the like. The load from the clips and stamps on the supports is carried down through a central post. Another embodiment of rack is adapted to be straight and wall mounted with spaces provided to permit snap-on of the clips.

Abstract: An ink stamp having movable type bands. The stamp includes an outer housing having a die plate located at its lower end and carrying an ink impregnated stamp. A frame is mounted for vertical movement within the housing and carries a series of endless type bands with each band having a plurality of spaced type characters with the lowermost character in each band adapted to project through an opening in the die plate. An upper handle or knob is connected to the frame and by pulling upwardly on the handle, the frame and bands can be raised above the die plate to a position where the bands can be rotated to change the lowermost type characters, as desired. The stamp also has a provision to adjust the heights of the type bands relative to the outer housing to insure that the lowermost operating type character is at a level flush with the lower surface of the stamp in the die plate.

Abstract: A hand operated ink stamp comprising an outer casing having an open bottom and an opening in the upper surface. A printing die impregnated with ink is disposed within the casing and is carried by a die holder having an upper magnetically susceptible surface. Mounted within the upper portion of the casing is a magnet, and the magnetic force will hold the die holder and die at a raised position above the surface to be printed. A stem is mounted for sliding movement in the opening in the upper surface of the casing and is connected through a ball and socket joint to the die holder. Manually depressing the stem will overcome the magnetic force to release the die holder from the magnet and cause the die to contact the surface to be printed. The position of the magnet within the casing can be adjusted to thereby vary the printing impression.

Abstract: A method and apparatus for producing printing patterns through the use of a liquid photosensitive resin system. A partially cured resin backing member is applied to a vertical supporting surface and a glass cover plate having a photographic negative mounted on the glass surface is positioned in spaced relation to the backing member. A liquid uncured photosensitive resin is introduced into the space between the backing member and the photographic negative, and an ultra-violet lighting unit is then positioned adjacent the glass cover plate to expose portions of the resin to the light through the photographic negative, causing the exposed portions of the resin to cure or crosslink. The lighting unit is oscillated to provide tapered edges on the exposed crosslinked areas of the resin. Following the crosslinking, the pattern can be removed and the uncured portions of the resin can be washed from the pattern.

Abstract: A molding plate for use in molding printing plates. A type-form plate bearing raised printing or indicia is coated with graphite and placed in a mold cavity with the printed surface being at an angle to the vertical and facing upwardly. A liquid thermosetting resin containing reinforcement is poured into the mold cavity and air is expelled from the upper end of the cavity. The resulting cured thermosetting resin plate has recessed printing impregnated with graphite and serves as a molding plate for forming printing plates from rubber or other materials.
