street, Rotherham.—A rope haulage clip constructed in the
form of a hinge, in one side of which is a groove for receiving
the rope, and on the opposite side a, tenon which compresses
the. rope in groove when the two sides of hinge are pulled
together by eye bolt and wing nut. The required grip on rope
to suit the load to be hauled is adjusted by wing nut, so
that the rope may be allowed to run freely through clip, or
load taken up at will, without it being necessary to detach
clip from rope: A boss for connecting clip by chain to
corves is placed in such position that its line of stress is almost
parallel to the rope, so that no kinking of the rope is
caused by hauling stresses. The clip is fitted with renew-
able gripping piece. Let A, B be the two sides of hinged
pivoted at R, and when permanently assembled and securely
riveted is quite free to
open and close. C is eye
bolt pivoted in B, and D
is wing nut, by which the
two sides of hinge A and
B are pulled together to
grip the rope. The con-
struction of the wing
nut. is such that it guards
the eye bolt from damage
by shock, that would
otherwise bend or break
the bolt, .also the bolt not
projecting through the
nut, a better grip of wing
nut is allowed for the pur-
pose of operating the clip.
In body A a receptacle is
formed for holding the
loose renewable gripping
piece E, that sits on four
strong springs, which fit

clip to adjust itself to any inequalities in rope due to either
haulage stresses or wear. The loose gripping piece E is
retained in receptacle by two loose stops S, S, that fit each
side of hinge boss of the member B, and they are kept
permanently in position by the hinge pin passing through
them and holding them firmly against projections formed
inside the hinge jaw of member A as shown in fig. 2. Eig. 1
shows elevation of members A and B before assembling; on
A is shown boss with hole H, to which is permanently
secured eye of haulage chain, also in each side of jaw for
hinge are shown stops S, S, that retain the loose gripping
piece E in receptacle formed in body A; fig. 2 is a sectional
elevation through M, N, with clip closed in position for
gripping rope, and shows how stops S, S, retain loose
gripping piece E in receptacle, and fit projections formed in
hinge jaw of member A; fig. 3 is an elevation of stop S
and loose gripping piece; fig. 4 is an elevation of wing
nut adapted for either spanner or hand. (One claim.)

22735 (1914). Improvements in or relating to Miners'
Safety Lamps. W. Best, of Providence House, New Park-
street, Morley, Yorkshire.—Relates to improvements in the
burners of miners’ safety lamps, and particularly to burners
wherein two concentrically mounted wick tubes carry between
them a circular wick, whose flame is regulated by means of
two slidable or telescopic sleeves, one of which is situated
within the inner wick tube, and the other on the outside of
the outer wick tube, the said two slidable sleeves being con-
nected together, and being adapted to be moved simul-
taneously up and down through the medium of a screwed
spindle in direct engagement with a projecting lug formed
on the outer sleeve, and which is passed vertically through
the oil vessel of the lamp. The object of the invention is to
provide an improved burner, which, while being very simple
to construct, will be efficient in operation, and ensure the
free and uninterrupted burning of the wick flame; and the
invention consists in the provision of a burner having an
inverted V-shaped opening formed through the side walls of
the two wick tubes near the base-thereof, for allowing air to
pass up the centre of the burner by way of the inner wick
tube, while the inner and outer slidable or flame-regulating
sleeves of the burner are connected together by a rod passed
through the said inverted V-shaped opening in the side walls
of the wick tubes, so as not to interfere with or impede the
flame of the wick. Fig. 1 is a sectional elevation' of the
lower portion of a double glass cylinder lamp, fitted with a
burner in accordance . with

10, concentrically mounted in a base flange 11, carried within
a recess 12 of the oil vessel 1, and fixed therein by a thumb-
screw ring 13, and through the side walls of the burner is
formed an inverted V-shaped opening 14, by way of which
atmospheric air entering the lamp is free to pass and travel
up through the central passage 15 of the burner, while into
the space between the two tubes 9, 10, is passed a wick 16,
adapted to be raised and lowered by means of a pair of pinion
wheels 17, through a milled-headed spindle 18; the said wick
16, which is a broad flat wick, is introduced at the base of the
burner, and is caused to ascend to the top of the burner.tubes
9, 10, by rotating the pinion, wheels 17 through their spindle
18, and be thereby transformed into a tubular wick as shown.
The burner tubes 9, 10, are provided with an inner sleeve 19,
and an outer sleeve 20, connected together by a rod 21,
passing through the opening 14, in the side 'walls of the
said burner tubes, so as not to interfere with the flame of the
wick when burning, and the outer sleeve 20 is formed with
a projecting lug 22 carried on the screwed end 23x of a spindle
23, passed vertically through the oil vessel 21, and provided at
its base with an operating head 23p, by means of which latter
the spindle 23 is rotated to raise and lower the sleeves 19, 20,

simultaneously, and so cause them to act as a flame regu-
lating and extinguishing' device. The atmospheric air enter-
ing the lamp is admitted by way of the space 24 between the
two glass cylinders 7, 8, and through the perforated wall 5
of the dome 6, to the burner, some of the air so admitted to
feed the flame passing direct to the wick at the exterior of
the burner, and some by way of the opening 14, and up the
central passage 15 of the burner, to assist the combustion.

THE ACQUISITION OF ENEMY PATENT RIGHTS.

The following list of British Patents, which have been
granted in favour of residents of Germany, Austria, or
Hungary,' is furnished in view of the new Patents Acts,
which empower the Board of Trade to confer upon British
subjects the right to manufacture under enemy patents,
which right, when acquired, can be retained after the war,
and is specially compiled for the Colliery Guardian by
Lewis Wm. Goold, chartered patent agent, 5, Corporation-
street, Birmingham. It is desirable in the first instance to
obtain the latest particulars upon the Patents Register. If
any patent listed has been assigned to a non-enemy pro-
prietor, the law does not apply.

3926/07. Winches. Two independent alternately braked
and working motors are employed to drive the
i drum, one for heavy loads, and the other for
light loads. Vereinigte Maschinenfabrik

6746/07. Furnaces; charges, agitating. Relates to a
method of attaching the stirring arms of
mechanical roasting furnaces to their shafts.
The vertical shaft is provided with the usual
transverse passages to receive the ends of the
stirring arms, which are tapered to facilitate
their insertion, and are provided with projec-
tions to prevent radial movement; these pro-
jections are brought into engagement by
turning the arm in an horizontal plane. W.
Troeller, Germany.

7108/07. i Mine props. Mine props are formed from
' pulverised waste stone, such as tufaceous lime-
stone, etc. One form consists of a cylinder of
! compressed waste stone closed by a bottom
piece, and covered with a layer of .shavings,
paper, etc., impregnated with fireproof
material. The cylinder is fitted with a piston
formed from pulverised stone and covered with
shavings, etc., and fitted with a large head,
the piston resting upon a filling of gravel or
waste stone. In a modification, the prop is
hollow, the piston being supported by means
of compressed air. The piston may be dis-
pensed with, the cylinder being then made
solid. F. Nellen and A. Voigt, Germany.

7375/07,; Rope grips. Consists in providing rails at suit-
; able positions on the track adapted to engage
j sliding surfaces or rollers on the rope grip to

prevent the grip from tilting as the operating
lever is moved; guide rails are also provided at
curves. The cable grip, or one of its jaws, is
provided with <a sliding surface or rollers which
engage with guide rails placed at the necessary
positions on the track. To take up the lateral
pull of the hauling rope at curves, a guide rail
bent to correspond with the curve engages a
roller mounted on a vertical pivot on the grip.

7650/07. Coke ovens. In an horizontal regenerative coke
oven, gas is supplied to the upper and lower
end alternately of each flue as the draught is
reversed, so that each flue has a continuous
supply of gas, and is not heated merely by
combustion products. Each flue may be sup-
. plied with gas from the main through a
channel and nozzles. In the ribs between the
flues are air flues, which serve to convey air
for combustion, or combustion products, accord-
ing to the direction of the draught, and which
may be formed one in each rib, or one to several
flues. F. J. Collin, Germany (dated April 4,
1906).

Damage of Vessel During Coal Loading. — In the Com-
mercial Court of the King’s Bench Division, last week,
before Mr. Justice Bailhache, Messrs. William Cory and
Son, coal shippers and merchants, of London, were proceeded
against by the Scholefield Steamship Company, of Sandhill,
Newcastle, to recover compensation for damage done to the
ss. “ Eversley ” in discharging a cargo of coal at Albert
Dock in October 1914. Liability was denied by the
defendants, who stated that the ship’was not a collier, and
that her interior structure rendered her unsuitable for the
use of the electric crane and grab, and that it was impossible
to avoid doing certain damage to the vessel.—For the
plaintiffs, Mr. Mackinnon, K.C., said that the damage was
done in discharging cargoes of coal from the “ Eversley ” at
the Albert Dock hoist. It had been agreed that his lordship
should be asked to decide the question of liability only. If
the defendants were held to be liable they would be able
to get the damages assessed by referees. The defendants
discharged the coal by. electric crane with a grab, and great
damage was done to the “ Eversley ” in unloading the
cargoes, owing, as the plaintiffs alleged, to negligence on the
part of the defendants.—Mr. Justice Bailhache, in giving
judgment, said that the “ Eversley ” was under charter
for four voyages, and the defendants undertook to discharge
the coal obtained from their collieries. The ship sustained
a good deal of damage when discharging coal at Albert Dock
on the first occasion, and still more on the second, but there
was no appreciable damage on the third occasion. The
damage was caused by the method of discharge. Messrs.
Cory had, at the Albert Dock, huge cranes, to which were
attached grabs. The apparatus used at this hoist was com-
paratively new. It was designed to work in connection with
the modern type of collier. To this appliance came the
“ Eversley,” which was not a modern collier, but an ordinary
tramp steamer, with the ordinary holds to be found in such
vessels, and it was obvious that the grabs could not be got
into the wings, or more than 3ft. away from the hatches.
As soon as the grab was lifted from the coal there was
a swing into the centre hatch, and the stanchions were
smashed. The grab knocked against the side of the ship,
and the ceiling and No. 4 hold were damaged, as well as
the hatchways. The battens were also torn off at the
side of the vessel. The plaintiffs therefore claimed that the
defendants were liable, by reason of negligence in dis-
charging the cargoes, for the damage done to the
“ Eversley.” But they did not allege negligence by the use
of these grabs, although they might have done so. The
question was not whether the grabs were unsuited for the
work, but 'whether the damage was done by their use. His
lordship said he thought there was some negligence in the
use of the grabs, and he had no doubt a great deal of the
damage was done by trying to get them as far as possible
into the hold. He gave judgment for the plaintiffs for so
much of the damage as the assessor would say was due to
the negligence of the use of the grabs, and not to the fact
that they were unsuitable for this particular work.
