uncut to hold the two wedge-shaped parts together, the saw-
cut extending into the fuse-opening, the arrangements being
such that when the two parts are separated the portion of

the said part to move away from the fuse without disturbing
the latter. (2.) A tamping-plug having a fuse-opening ex-
tending longitudinally therethrough, said plug being com-
posed of two parts having inclined engaging faces, the fuse-
opening in one part being open on one side adjacent the
inclined face to allow the said part to move away from the
fuse without disturbing the latter during the tightening
operation. (3.) A tamping-plug having a fuse-opening ex-
tending longitudinally therethrough, said plug being com-
posed of two parts having inclined engaging faces. (4.) A
tamping-plug having a fuse-opening extending longitudinally
therethrough, said plug being composed of two parts having

water to pass and closing against its return, the valve being
also so arranged that the extent of its opening can be regu-
lated, and so that it may be prevented from opening when
desired.

Claims.—(1.) The combination, arrangement, and con-
struction of injectors substantially as described, and illus-
trated by Figs. 1 and 2 of the drawings. (2.) The combina-
tion, arrangement, and construction of injectors substantially

ments in railway signalling and communicating apparatus.

Claims.—(1.) Railway signalling and communicating
apparatus consisting of a wire or wires stretched parallel
with the railway-track upon insulated stanchions, and

being in electrical communication with the signal-box, and
said brush being in electrical communication with a bell
and indicator upon the locomotive, substantially as and for
the purposes specified. (2.) In railway signalling and com-
municating apparatus, a wire or wires stretched parallel with
the railway-track upon insulated stanchions, and a contact-
maker operated by a signal-lever in the cabin, substantially
as and for the purposes specified. (3.) In railway signalling
and communicating apparatus, a bell upon the locomotive
operated mechanically by a trip lever and a wire supported
alongside the track, together with a brush upon the loco-
motive, whereby electrical communication may be completed
between the signal-box and said locomotive, substantially as
and for the purposes specified. (4.) In railway signalling
and communicating apparatus, a mechanically operated bell
upon the locomotive, a brush making contact with a wire
stretched parallel with the railway-track, an indicator,
electric bell, and telephone, also carried by said locomotive,
the whole being arranged and operating substantially as
and for the purposes specified. (5.) In railway signalling
and communicating apparatus, a rotating brush consisting
of a number of short lengths of wire projecting from a
spindle mounted in bearings carried by adjustable brackets
projecting downwardly from the locomotive, substantially as
and for the purposes specified. (6.) In railway signalling
and communicating apparatus, a contact-brush in which
a number of short lengths of wire are clamped in a socket
carried by a bracket adjustably mounted upon the loco-
motive, substantially as and for the purposes specified.

No. 13666.—30th May, 1901.—JAMES PALMER CAMPBELL,
of Wellington, New Zealand, Registered Patent Agent
(nominee of William Chapman, of 5, Norfolk Street, Strand,
Westminster, England, Electrical Engineer). Improvements
in or relating to track-construction for electric railways
operated on the conduit system.

Claims.—(1.) A conduit electric railway in which the
underground construction at switches, turn-outs, and cross-
ings is carried out by means of cast yokes, substantially as
described. (2.) For a conduit railway, a cast yoke having
two orifices, substantially as described. (3.) For a conduit
railway, a yoke formed of two parts, each having a conduit
orifice, said parts being separated by a distance-piece, to
which they are secured, and the width of which can be
varied as the tracks diverge, substantially as described.
(4.) For a conduit railway, a yoke containing three conduit
orifices, and formed of parts each containing one conduit
orifice, and separated or not by distant-pieces, substantially
as described. (5.) A yoke for use at a crossing in which the
tracks make a large angle with each other, and having ex-
tensions for supporting the points of the conduit slots, sub-
stantially as described with reference to Figs. 22 to 24 of the
drawings. (6.) In a conduit railway, diverting the slot
from the central position at or near a switch or turn-out for
the purpose specified. (7.) Conduit yokes, constructed sub-
stantially as described with reference to any of the forms
illustrated in Figs. 2 to 15 or 17 to 20 of the drawings, for the
purpose specified.

(nominee of George Westinghouse, of Westinghouse Building,
Pittsburg, Pennsylvania, United States of America, Manu-

vehicles.

Claims.—(1.) In a coupling for railway-vehicles, a pivot-
block rigidly connected to the movable part of the draw-
gear, having a semi-cylindrical pivotal face and sides tapered
towards the front end, fitting freely in a vertical central re-
cess in the coupler-shank, so as to permit an angular motion
of the coupler-shank in a horizontal plane around the said
semi-cylindrical pivotal face of the block, substantially as
described. (2.) In a coupling for railway-vehicles, a coupler-
shank pivotally connected to the movable portion of the
draught-gear, and so constructed that a lateral movement
beyond a certain distance in either direction compresses the
draught and operating-spring, whereby the said spring tends
to return the coupler-head to its normal position, substan-
tially as described. (3.) Couplings for railway-vehicles con-
structed and operating substantially as described with re-
ference to the drawings.

into suitable staples affixed to the jambs of a door or into
mortises out in the said jambs, so as to cause the said strip
of metal to bear firmly upon the mat used with the said
door, and thus hold the said mat in position, essentially as
described. (2.) The device described, and illustrated in
Figs. 8, 9, and 10 of the drawings, for holding door-mats in
position—that is to say, a wire stretched tightly over the
mat, to be so held, one end of the said wire being attached to
a screw-eye screwed into one of the door-jambs, and the
other end of the said wire being gripped by a holdfast or
grip affixed to the other door-jamb, all essentially as de-
scribed.
