    Abstract: This invention relates generally to signs such as are used for house numbers, door plaques, and other identification items, and particularly to the type of signs in which the number or letters are removable and replaceable. The novelty of this invention resides in all the components, such as the outer frame, the background, and the numbers, letters, or symbols, being replaceable or interchangeable. The above mentioned components of the sign are combined by simple press fitting, or by means of a set of screws which are also used to attach the said sign to a wall or similar surfaces.

  • Patent number: 4002250
    Abstract: This invention consists of a metal plate pickling rack which eliminates manual handling at several stages of the pickling operation, and provides a safety factor for the operator against contact with the pickling acid. The rack consists of an acid resisting metal rack in which the plates are contained in two opposite piles. The plates are spaced from each other, are supported at their bottom edges by alternately spaced notches in the opposite walls of the rack, and are supported at their top edges by leaning against a pair of removable rods centrally located in the rack. When the entire pickling operation is completed, the upper plate edge supporting rods are removed and the plates fall alternately out of the rack into a uniformally stacked pile which is ready for shipment or the next operation.

  • Patent number: 3994652
    Abstract: This invention consists of a combined rolling pin and dough cutter. It is made up mainly of a central shaft provided with a handle at each end, and a series of abutting cylindrical rollers, all of the same diameter, rotate freely upon the central shaft to function as a rolling pin. To perform as a dough cutter, a series of circular cutting discs are inserted between the rollers. These discs are of a larger diameter than the rollers, so that their cutting edge extends beyond said rollers. One handle of the shaft is permanently fixed to the shaft while the other handle unscrews from the shaft to allow the insertion of the rollers and discs. One of the handles of the shaft is bored with a longitudinal hole into which is inserted a center pin which is used for cutting circular sections of dough used in pie making.

  • Patent number: 3963137
    Abstract: This invention consists of a vehicle for handling multi-furrow ploughs, which are very heavy and are equipped with only one wheel in the rear, when not attached to a tractor during operation. It consists of a two wheeled cart provided with two hooks attached to the main body of the cart, by means of which the front end of the plough is picked up and held, and a central arm for pulling the cart which is swivably attached to the main body. A ratchet operated cylinder having two oppositely threaded screws, one going in or out at each end simultaneously, is swivably attached to the arm and to the main body of the cart, so that turning the ratchet in one direction expands the distance between the screw ends thus lowering the hook towards/the ground to pick up the front end of the plough, and turning it in the opposite direction reduces that distance and lifts the hooks and front end of the plough to make it mobile.
