MANUFACTURE OF SCOOPS.--S. Geo. Knapp, Woodhaven, N.Y.--This invention relates to an improved mode of manufacturing sheet-metal flour, grain, and other scoops, and consists in forming the bowls in one piece of metal, without seams or joints, by stamping up sheets of metal into the form of a trough, with a flange around the top, and cutting the same transversely in the center, with blanks for the bowls of two scoops, to be finished by trimming or shaping the cut ends, turning down the flange at the top, for stiffening either over wire or not and attaching the handle; the object being to produce scoops with bowls formed in one piece, and shaped at the base or in the part where the handles are connected, and to smoothly effect an economy of labor by stamping two blanks at one blow of the drop press, and also to control the metal under the action of the drop better in shaping the deep curved part of the base so as to upset and stiffen the blanks thereat. BORING MACHINE.--E.C. Barton, Bloomsburg, Pa.--This invention relates to improvements in wood-boring machines, whereby it is designed to provide a simple and efficient arrangement of frame operating devices and feeding table for boring light articles to be presented to the machine by hand. HASP LOCK.--E.R. Culver, New London, Conn.--This invention relates to improvements in that class of locks where the locking devices are incased within a hasp, and a hook is used in connection with the hasp for locking, or independently for fastening the door without locking. WATER WHEELS.--W.J. Thompson, Springfield, Mo.--This invention relates to improvements in that class of horizontally running wheels, which receive the water from above or below on curved buckets taking the water at one side and discharging it at the other, and it consists of an improved arrangement of vertically oscillating gates, which, when open, form chutes for the water; it also consists of an improved means for working the gates. PIPE COUPLING.--J.D. Ware, Savannah, Ga.--This invention relates to improvements in pipe couplings, and consists in forming a dovetailed groove across the end of one part, with an annular recess in the bottom around the bore for a packing ring, and fitting on the other part a dovetailed projection for engaging in the groove, and in arranging on one of the parts an eccentric ring to work against the head of the projection and force it tightly into the groove.
