MECHANICAL INVENTIONS.
Mr. William B. Hickman, of Sterling, Kan., has patented a swage to be used in welding the triangular bar which is to form the flange of a plow point or share to the body of the same.
Mr. Lucius S. Edleblute, of Cincinnati, O., has recently patented what he calls the rubber cushioned spoke and hub. This is an improvement in the class of vehicle wheel hubs having an elastic band or annular portion which surrounds the journal box and on which the butts of the spokes rest, so that the wheel is rendered elastic and more durable, also comparatively noiseless when running on stony pavements, roads, or streets.
Mr. George Richards, of Boxbury, Mass., has patented a steam muffler composed of two plates of a diameter very much greater than the diameter of the pipe through which the steam escapes from the boiler, so that the steam has room to expand before escaping to the outer air, its expansion effectually deadening the noise caused by the passage through the contracted escape pipe.
