John Snyder, Williamsfield, Ohio.-This invention has for its object to furnish an improved plow for plowing and hoeing corn, which shall be simple and strong in construction and will do its work well.
James H. Glass and Albert J Glass, McGregor, Iowa.-This invention has for its object to furnish an improved attachment for reapers of that class in which the rakes act as beaters, in the place of a reel, and are made to descend occasionally to sweep the bundle from the platform, so that the third, fourth, sixth, or any other desired rake may sweep the platform and deliver the bundle.
John W. Hadfield, Newtown, N. Y.-This invention relates to a modification of an improvement in sky rockets for which letters patent were granted to this inventor bearing date Nov. 28, 1865. The original improvement consisted in a novel application of wings to the body or "carcass" of the rocket, whereby the use of the ordinary guide stick was rendered unnecessary and the rockets rendered capable of being packed for transportation much more compactly than when provided with sticks. The present invention also consists in a novel manner of attaching the wings to the body or "carcass" of the rocket, whereby the same advantage is obtained as hitherto, at a less cost of manufacture.
James Thoms, South Boston, Mass.-This invention relates to a new and improved manner of attaching the E-string to the tail piece of a violin, whereby a comparatively small portion of said string is wasted in case of breakage.
James E. Covert, Townsendville, N. Y.-This hame tug, according to the present invention, is made of a strip of malleable iron or other suitable material, perforated or provided with V-Shaped holes or slots having a center tongue piece, for the reception of a V-Shaped block fixed at one end of the trace, by means of which block the trace is engaged with the hame tug, where through a suitably arranged spring slot that strikes against the end of the tongue to the said V-slots, the block is held firmly in place, and consequently the trace fastened to the hame tug.
F. J. McFarland, San Francisco, Cal.-This invention relates to the location of the center boards of boats and sailing craft of all kinds, but is designed more particularly for freight carrying vessels. It consists simply in employing two center boards and locating the same at the extreme ends of the hull.
George W. Van Dusen, Williamsburgh, N.Y.-This invention consists in a novel connection and arrangement of levers and valves between the plane of movement of the perforated surface or surfaces, and an airchest or chests, and the keys or levers for opening the valves to the reeds or for operating any other mechanism suitable for producing tones, whereby through such perforated surface or surfaces the mechanism forming the connection between it and the sounding mechanism will be operated through the perforations to produce the sound or note or notes desired, of whatever length such notes or sounds are to be.
