[No. 2

provide simple and efficient means for automatically moving
the ribbon widthwise with respect to the printing-point.
Another object is to provide in a typewriting-machine means
adapted to shift the ribbon with the platen, such that the
ribbon will at all times be held within the field of the types,
whatever its position with respect to the platen when the same
is shifted. Other objects will be in part obvious and in part
pointed out. . . . The inking-ribbon 22 is supported
upon spools supported at either end of the machine, and is
adapted to be fed longitudinally of the platen step by step
by any desired actuating-means, controlled by the universal
bar 23, upon which the several key-levers rest, said bar being
connected by means of a link 24 with an arm extending
from a universal rock-shaft 25. Ribbon 22 is supported
in the vicinity of the impression-point of the platen by a
vertical carrier, through which the ribbon is threaded, said
carrier being comprised in the present instance by a pair of
upright members 26, which merge at their lower ends and
are fulcrumed at 27 upon an arm 28 rigidly secured to a
shaft 29 journaled in the lower portion of the machine. Shaft
29 extends rearwardly, and has loosely mounted thereon
an arm 30, and this arm is connected at its outer end by means
of a pivot-pin 31 with a link 32, the upper end of which is
shaped to fit about an eccentric 33 formed upon the outer
face of a ratchet-wheel 34 journaled upon pivot-screw 17.
Pivot-pin 31 has extended therefrom a spring 35, herein shown
looped in its middle portion, and the outer end of said spring
is fast in a collar 36 rigidly secured to shaft 29. By means
of this construction it will be seen that eccentric 33 is re-
siliently connected to shaft 29, and that an upward or down-
ward movement of links 32, as when the eccentric is rotated,
will serve through said shaft and arm 28 to raise or depress
carrier 26 and thereby move the ribbon widthwise with re-
spect to the printing-point. Erected upon channel-bar 15
of the platen-frame is a standard 37, which carries at its upper
end a pivotally mounted gravity pawl adapted at each return
movement of the carriage to be carried into engagement
with one of the teeth of ratchet-wheel 34, rotates the same,
and compels thereby a slight rotative movement of eccentric
33, thereby moving link 32 in an upward or downward direc-
tion and causing a corresponding movement of the ribbon-
carrier. Carrier 26 is guided near its upper end by means
of pins 39 extended from bed 2, which take through longi-
tudinally extending slots 40 provided in each of the upright
members of the carrier. These pins, while forming guides
for the carrier, insuring its movement in a direction at right
angles to the longitudinal feed of the ribbon, also operate
to limit the upward or downward movements, thereof when
the same is moved during the shifting of the platen-frame
for upper- or lower-case printing.

[NOTE.—The above extracts from the specification are inserted in place
of the claims.]

(Specification, £1 1s. ; drawing, 4s.)

No. 23469.—13th September, 1907.—OSWALD COATES, of
Christchurch, New Zealand, Accountant. Improvements in
shifting points for tram-lines.*

Claims.—(1.) In lines of rails, at facing points thereof,
in combination, the point secured to a bent sliding bar,
having wedge-shaped working ends, with a “finder” wheel
formed to go deep enough with its deeper flange to move the
said bar before the car comes to same, all substantially as
shown on the drawing, and as described. (2.) In com-
bination with a car and the rails it runs on, a facing point
so connected to a bent bar having wedge-shaped working
ends, with a loose wheel on the car that can be depressed
and by displacing the working end of the bar, moves the
point, all substantially as set forth. *(3.) In points of rails, in
combination, a car having wheels placed before the usual
car-wheels, capable of being raised or lowered deeper than the
car-wheel flanges go, and when so lowered can displace the
projecting working end of a wedge-shaped bent bar con-
ected with said points, for moving same as desired, with
dirt-wells for keeping said points clear, all substantially as
set forth.

No. 23530. — 25th September, 1907. — ALFRED ERNEST
SLIPPER, Sawmiller, and DAVID JOHN SMITH, Hotel-pro-
prietor, both of Kokiri, Greymouth, New Zealand. Im-
proved belt-fastener.*

Claims. —(1.) A belt-fastener consisting of two end plates
with two side plates pivotally secured to them between
which the ends of the belt are passed, substantially as de-

scribed. (2.) A belt-fastener according to claim 1, in which
the side plates are pivoted above their centres so as to give
greater leverage, substantially as described. (3.) The com-
bination with a belt-fastener according to the preceding
claims, of a central plate lying between the belt-ends and
resting in notches formed on the upper edges of the end
plates, substantially as and for the purposes set forth.
(4.) The complete belt-fastener substantially as described
or illustrated in the drawings.
