FERRULE.--Archibald Shaw, Philadelphia, Pa.--This invention relates to a
new and improved ferrule for the handles of tools and other implements,
and it consists in providing the interior of the ferrule with oblique
spurs or projections, disposed or arranged in such a manner as to admit
of the ferrule being driven on the handle and at the same time prevent
it from casually slipping off therefrom. The object of the invention is
to obviate the necessity of tacks or screws being used to secure the
ferrule on the handle, as well as the pinching of the same externally to
form a burr to sink into the handle to effect the same end.
SUCTION OF VACUUM PUMP AND BLOWER.--John Doyle and Timothy A. Martin,
New York City.--This invention consists in arranging valves and air
passages with a hollow cylinder or drum having an oscillating movement,
and provided with a chamber or chambers to receive water, mercury or
other fluid, whereby an exceedingly simple and compact pump or blower is
obtained, one not liable to get out of repair or become deranged by use.
