HAME TUG.--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.
CENTER BOARD.--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.
MUSICAL INSTRUMENT.--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.
