UPRIGHT PIANO.--Geo. C. Manner, New York city.--This invention consists in placing the strings of an upright piano in an inclined position in the frame instead of a perpendicular one, as heretofore, for the purpose of enabling the hammer handle to be pivoted so near the strings that when the hammer head is driven up against them, it shall necessarily fall back again by its own weight. CARPET CLEANER.--Alexander Stevenson, New York city.--This invention relates to new and useful improvements in carpet cleaning devices, having for its object to provide a simple and efficient apparatus consisting of a yielding bed, brushing rollers, moving rollers, and a beating apparatus, whereby the carpet, being bound upon a roller, or rollers, may be moved along, from time to time, over the said yielding bed and brushing rollers, and be beaten and brushed. COTTON CULTIVATOR.--I.W. Burch, Fayette, Miss.--This invention comprises a pair of plows suspended from the frame of a truck so as to work on both sides of the row, for "barring off" or scraping the weeds and earth away from the row, also, a pair of rotary cutters having oblique blades for throwing away from the plants, and designed, also, to work on both sides of the rows, and closer to the plants than the plows, both sets of devices having vertical vibration. WATER WHEEL--Geo. W. Cressman and Burt Pfleger, Barren Hill, Pa., and Nice Keely Roxborough, Pa.--This invention relates to improvements in turbine wheels designed to produce an arrangement of the gates within the bucket rim (the water being secured from below, and the wheel being made hollow, for the reception of the water, and to provide space for the said gate), in a manner calculated to relieve the wheel of pressure from the water, either in an upward or downward direction. ATTACHING FLY AND MOSQUITO BARS TO WINDOWS, DOORS, ETC.--James Hebron, Buffalo, N.Y.--This invention relates to improvements in attaching fly and mosquito bars to window sashes or frames, doors, or other light frames to be used in combination with window frames or doors, and consists in attaching one edge of the cloth to a round or other shaped bar or rod of wood or metal, by binding thereon and sewing, passing the thread spirally around the bar or rod, and then securing the rod to the sill or frame, either on the surface thereof, or in a groove formed therein, then stretching the cloth across the window and securing it by clamping another rod down upon it by staples, either in a groove or not, and, in some cases, securing the ends in a similar way. It is also proposed to stretch the cloth over or under these rods.
