Abstract: Disclosed is a stationery case for keeping writing materials, which comprises an ornament mounted on a compression spring which is fastened in the interior of the casing. The ornament has a magnet fastened therein and is pressed and released so that clips which are received inside a curved recess in the casing can be taken out of the casing and placed on a recessed surface portion on a cover at the top of the casing for ready use. A plurality of compartments are made inside the casing in the portion opposite to the curved recess for keeping a variety of writing materials. A whistle is fastened inside the casing and is controlled to make a sharp, clear sound during a downward stroke of the ornament.

Abstract: In a supply head of a nut feeder, a guide member having both side walls guiding both end surfaces in minor axis direction of a flange portion of a transferred T-nut is fixed to the front end of a rod arranged movable forward and backward within a sleeve and magnetized for prescribed time so as to attract the T-nut to its holding surface at the top end. When the T-nut is attracted by the holding surface at the top end of the rod and the rod is moved forward to the welding position of the work, the rod is demagnetized and the T-nut becomes free thereby the T-nut abuts on the guide pin on the work by inertia force and is rotated and held to prescribed position on the work. In this case, both end surfaces in the minor axis direction of the flange portion of the T-nut are guided by both side walls of the guide member, and the T-nut is rotated in proper attitude and held to the correct welding position on the work.

Abstract: A parts supplying apparatus for carrying and supplying a part such as a projection nut to a predetermined point in space comprises a telescopic supply rod including an outer and inner shaft and, a magnet being fixed to a proximal end of one of the two shafts. The supply rod first extends in its entirety towards the predetermined point, or destination, with the part attracted and held at the proximal end by way of the magnet. When the part reaches slightly short of its destination, relative displacement in longitudinal direction of the outer and inner shafts takes place so that the magnet is moved away from the part until its magnetic force on the part is no more influential, whereupon the part is allowed to fall under gravity down to the destination accurately.

Abstract: A rod feeding and placement mechanism for use in apparatus for making hanging file folders comprises a magazine wherein a plurality of flat, elongated, metal rods are vertically stacked, one above another. A pair of laterally spaced-apart, horizontally disposed, slightly convergent, contra-rotating de-stacking screws located below the magazine engage the lowermost rod in the stack and advance or feed it laterally along a rod-path. Another pair of laterally spaced-apart, horizontally disposed contra-rotating top screws above the de-stacking screws then receive the rod from the de-stacking screws and advance or feed it further along the rod-path to an at-rest position located above a flat paperboard blank. Guide rails and magnetic strips support the rod as it advances along the rod-path. The rod is releasably maintained for a moment in the at-rest position by permanent magnets.

Abstract: A pin and staple box composed of an outer case with the opening for placing the pins and staples and an inner box to be placed within the outer case. The upper end of the inner box can be ejected outside the top of the outer case. At the middle portion of the front of the outer case, a horizontally extended plate is formed. There is a small gap between the edge of the plate and the ejecting front plate of the inner box so that the ejection of the inner box shall not be hampered, and a chute is formed for placement of the metal pins, staples and the like. Further, on the front plate of the inner box, a magnetic element is installed. Thus, when the front plate of the inner box ejects to let a portion be exposed outside of the top of the outer case, the pins, staples and the like will affix to the front plate automatically, and the user can easily take them.

Abstract: A machine for making hanging file folders, each of which folders comprises a folded paperboard blank and a pair of support rods fastened to the upper edges of the folded blanks and includes a rod applicator mechanism comprising a conveyor for moving an unfolded flat blank having glue patterns thereon along a path; a mechanism for momentarily interrupting or stopping movement of the blank along the path; a pair of rod-dispensing magazines adjacent the path; and rod transfer mechanisms for transferring rods from the magazines and applying them to the glue patterns while the blank is stopped, whereafter blank movement resumes. The conveyor includes a pair of separable rollers between which the blank passes and by which it is advanced when the rollers are closed. The mechanism for momentarily interrupting movement of the blank effects momentary separation of the rollers and includes a stop member temporarily movable into the path of movement of the blank to arrest its progress after the rollers separate.

Abstract: To move a workpiece from one location to another, the main body of the transfer mechanism is raised on an air bearing and pivoted automatically or manually from station to station, with the workpiece being held by a gripping head mounted to one end of the main body by a tranfer arm. To control the gripping head, a piston, slidably mounted within the transfer arm, is biased away from the gripping head so that, when air pressure is applied, it is forced toward the gripping head and, when air pressure is removed, it is moved away from the gripping head with the gripping head being provided with any one of a number of interchangeable piston-controlled gripping devices. To control the air pressure in the transfer arm, two external sensing switches are mounted outside the main body to control the flow of air, which switches are activated when the body is lowered.
