This device will hold the slats in any required position, but when the
slat bar is subjected to a positive pull, the strip will slip upon the
face of the flange, against which it will be held by the action of the
spring strip. By means of the set screw, the parts may be so locked
together as to prevent the turning of the slats from the outside.
This invention has been patented by Mrs. Lizzie T. Gulick, of
Corsicana, Texas.
The British Armament at Victoria.
Some mistake appears to have been made in the recent announcement that
the British Government are sending out a number of eighty ton guns
for the coast defense of Esquimault and Victoria. Twelve sixty-four
pounders have been sent out from England, not for the armaments of the
forts, but to be placed on board the British ships of war belonging to
the Pacific squadron or to go into the naval reserves. Some time ago
the British Minister of War made application to the Canadian Pacific
Railway to know if they could transport one or more eighty ton guns
over their road. An estimate of the cost was given, with the model of
a car composed of three trucks, which it was proposed to use if the
shipment was made. Since then nothing has been heard of the eighty ton
guns. The officer in command of the British Columbia district does not
speak very creditably of the condition of the armament at that point.
The artillery armament is described as old, the carriages and limbers
are reported rotten and are falling to pieces, while the guns are
without sights. The batteries at Victoria and Esquimault, the officers
say, are in a discreditable condition.--_N. Y. Evening Post_.
A SIMPLE DEVICE FOR CRIMPING BOOTS OR SHOES.
[Illustration: LA FOLLETTE'S BOOT CRIMPER.]
The crimper herewith illustrated has a yoke-shaped stationary portion,
the jaws of which are formed with transverse corrugations. The top
of this yoke has a longitudinal slot, in which are pivoted the upper
reduced ends of movable inner jaws, whose operative faces have
transverse corrugations, arranged to always meet and fit within the
corresponding corrugations of the outer jaws. These inner jaws are
normally held open by a spring. The operating or crimping screw slides
freely through the slot in the yoke, extending between the inner jaws,
and on its lower portion fits a wedge-shaped clamping block, which is
drawn up between the inner jaws by turning the operating screw. The
outer end of this screw being placed in an aperture in the heel of the
last, or in other suitable position relative to a form over which the
leather is to be crimped, and the edges of the leather placed between
the jaws, the leather may be strained about its forming block as
desired by simply rotating the screw.
This invention has been patented by Mr. Elery B. La Follette, of
Flemington, West Va.
