bearing fit for the roller hubs, and impart stability to the
rollers. In practice, as one roller is pressed back by the
rope or cable clip attached to a wagon, the other roller is
turned forwards, and vice versa, as the last-named roller or

pulley is engaged, thus leverage is obtained which facili-
tates passage round a curve or bend. (Six claims.)

104460. Improvements in or Connected with Clips or
Gripping Appliances Used in Connection with Moving
Traction Cables, Endless Rope Systems, or the, like. A.
Parry, of Staveley, Sandheys, Waterloo, Lancashire.—This
invention has reference to clips or gripping appliances used
in connection with moving traction cables or endless rope
systems, such as are used in mines,, quarries, tramways,
railways, and the like, either for hauling or moving rolling
loads, as tubs or other vehicles, or dead loads as suspended
loads or the like, and of the type in which the movable
gripping jaw is operated by an eccentric headed pivoted
lever hinged on the other jaw device or part, and to which
the load is connected ; and it has for its objects and effects
to provide a clip or gripping appliance of the kind in
which both the gripping or clipping action and the releasing
action are effective and reliable, and can be easily effected ;
while at the same time it is very inexpensive and simple,
and yet strong, and it retains its effective and normal
action for a relatively great length of time, after long
usage, and the parts can be made and assembled without
machinery or fitting. Fig. 1 is a side elevation; fig. 2 is
an endless elevation ; fig. 3 is a plan of the apparatus ; and
fig. 4 illustrates the form of the appliance when used for
moving or carrying dead loads. v The clip or grip appliance
comprises three main parts, a gripping part 1, the upper
part of which acts in connection with the upper side of the
rope ; a gripping block or device 2, which works in con-
nection with the gripping device 1, and acts on the under-
side of the rope ; and a lever 3, which is carried on and by
the gripping part 1, and acts directly on the underside of
the gripping block or device 2 ; this lever being the part
which is connected to the rolling or dead load, as the case
may be, to be hauled or moved. The upper part of the
gripping part 1 is in the form of a hook, curved on its
under surface, and below is provided with projecting part
5, which constitutes a pivot journal, upon which the lever

device 3 is mounted and works, it being provided with a
button 6 at its outer end, which keeps the lever 3 in posi-
tion when placed upon it, as hereinafter described. The
lower gripping block or device 2 is generally in the form of
a saddle piece, having two flanges or flaps 7, by which it is
kept in its true position vertically and laterally, while
longitudinally it is held in position by lugs 8 on its ends,
which come on each side or edge of the grip part 1. The
outer edge of the head 9 of the lever 3 is in the form of a
part of a circle, and this part works upon the under side, of
the gripping block or device 2, between the flanges 7, which
is also curved ; and the centre of the circular portion of the
head 9 is eccentric to the axis of the journal 5, upon which
the lever 3 works ; so that when a strain comes upon it,
tending to move it to the left, the upper part of the head
9 of the lever moves upwards, and presses the block 2 on to
the under side of the rope 10, and correspondingly presses
the upper hook portion of the gripping device 1 on to the
top of the rope. With regard to the removal of the grip
from the rope, this is positively effected. This may be
effected quickly and cleanly by giving the head of the lever
3 a jerk or knock in the required way; and this can be
arranged to be readily done automatically by providing a
stop or tripping device such as commonly used in connec-
tion with which the lever will come. The button 6,
which projects over the edges of the journal 5, is disposed
at such an angle that, to place the lever 3 on the trunnion

2, it (the lever) must be placed in an angle in relation to
the part 1, which it does not take when the appliance is in
action ; that is, at an angle in which the gaps 13 on each
side of the hole 14 through which the journal 5 passes,
will pass over the ends of the button 6 ; after which, when
the lever is turned down, and the block 2 is in position
between the lever and the rope 10, the button will not
come opposite these gaps 13. The guides 8 are curved on
their inner sides, and the projections 11 of the block 2 are
curved at their ends so the action shall be easy. The
parts may in many cases be made of cast metal, such as
malleable cast or cast steel. A stop pin 15 is provided on
the inside face of the lever 3 to limit its circular move-
ment about the journal 5. (Five claims.)

104465. Improvements in the Construction of Gas
Washers and like Apparatus. G. K. Davis, 66, Deansgate,
Manchester.—This invention relates to improvements in
the construction of gas washers and like apparatus, and
particularly to apparatus of the type described in the speci-
fications of former patents, Nos. 2113/09, 5952/10, and
17005/14. The object of the present invention is to pro-
vide improved means for preventing the leakage of liquid
around the fanner shaft, and to this end the invention
consists in the provision in connection with the fanner shaft
within the washer of a centrifugal device in the form of a
disc, which throws off the liquid adjacent to the side of the
apparatus through which the shaft passes, in combination
with a grooved boss on the side of the apparatus through
which the shaft projects, the said disc being almost in con-
tact with the boss and partly encircling the same. The
use of such an arrangement effectively prevents the leakage
of liquid to the outside of the apparatus, and is piarticu-
larly advantageous when used with apparatus for the
de-arsenication of sulphuric acid. The accompanying
drawing represents a vertical cross section through one
form of device according to the invention, a is the side
of the apparatus, and b represents a portion of one of the
fanner shafts. This shaft, which is supported in inde-

pendent bearings (not shown) outside the washer, passes
through the casting or boss c, which somewhat resembles an
ordinary stuffing box, although no provision is made for a
gland, which is not necessary. The end of the said cast-
ing or boss c, which projects into the machine is grooved,
as shown at d in such a manner that any liquid running
down is guided away from the extremity of the boss c. e
is the disc which is keyed on the shaft close up to the
casting or boss c, the said disc encircling a part of the
projecting end of the boss, and having its external sur-
face increasing in diameter up to the point /. The rota-
tion of the disc e with the shaft b causes the liquid to be
thrown off the former at the largest diameter so that it is
prevented from finding its way to the outside of the
machine. In order to prevent any acid from “ creeping ”
along the shaft under the disc, an angular groove g is cut
in the disc e, the said groove being filled with acid-resist-
ing or any other suitable cement. The relative and actual
sizes of the boss and disc can be varied to suit the speed
of the shaft and the pressure within the apparatus. (Two
claims.)

Coal by Canal.—According to a published report, Mr.
Guy Calthrop, the Controller of Coal Mines, whose organi-
sation is now complete, is endeavouring to relieve the
pressure on the railways of the country by arranging for
the transport of more of the coal traffic by the canals. Mr.
Calthrop is, of course, working in conjunction with the
Canal Commission, who are heartily co-operating with him.
This policy will have the effect at once of relieving the con-
gestion on the railways, and . of setting free many more
w^agons for war and other purposes. The main idea, how-
ever, is to confine the distribution of coal as near as
possible to the locality in which it is produced. To expe-
dite the business of the Controller’s Department, district
superintendents are being appointed. One will reside in
each colliery area, and it will be his business to solve
problems on the spot on lines laid down from headquarters,
thus avoiding endless correspondence and delay.
