direction, two oscillatory sets of agitators, arranged in differ-
ent planes and having their adjacent portions formed as
knife-edges and their rear faces corresponding, substantially
as described. (14.) In a mixing or other similar machine

bination of the vessel in which the mixing is adapted to be
effected, an oscillatory set of agitators having their acting-

No. 16744.—5th August, 1903.—DAVID ALEXANDER POE,
Manager, and WILLIAM HERMANN SCHARF, Superintendent,
both of Montreal, Quebec, Canada. Linotype Machine.

Extract from Specification.—The following extract from
the specification is inserted in place of the claims: A
machine embodying our invention comprises in its general
characteristics a series of circulating matrices, each having a
female character and distributing-teeth and a series of cir-
culating expansible spacers to be used with the matrices ; a
keyboard representing the various characters and spacers, and
finger-keys to release them in the desired order ; mechanisms
for assembling the matrices and spacers in lines and for
transferring the lines successively from the assembler and
presenting them for alignment and justification and the
action of a casting-mechanism comprising a mould which is
designed to be filled with molten metal to produce the lino-
type or slug with its edge formed in the line of matrices ;
mechanisms for distributing the matrices and spacers, after
the casting operation has been finished, to their respective
magazines from whence they started, and mechanism for
trimming the type-bars and delivering them successively
into a suitable galley. Furthermore, in a machine em-
bodving our invention, the casting, trimming, and ejecting
mechanisms are arranged in a plane at an angle to the
assembler or to the plane of assemblage of composition, and
accordingly our invention comprises means for turning the
matrix line after its composition and transferring it to the
casting-mechanism, and in connection therewith various
other novel devices are provided in the casting-mechanism
and in the mechanisms for separating the matrices and
spacers, and transferring the former to their distributing-
mechanism and the latter to their magazine. In all linotype
or type-casting machines prior to our invention the matrices
falling from the magazine were assembled in line, and the
composed line was moved forward in the plane of assemblage
—i.e., in the same plane—to the casting-mechanism, and
thereafter moved bodily upward and rearward to a dis-
tributing-mechanism, whereas in a machine embodying our
invention the assembling-mechanism and casting-mechanism
are arranged at an angle to each other, and there is also
provided an intermediate assembler or line-support adapted
to be turned or having an oscillating or vibratory motion in
order to receive the line of matrices in one direction from the
assembling-mechanism and deliver it in a different direction
to the casting mechanism ; and whereas also in a machine
embodying our invention means are provided for turning the
composed line for presenting to the casting-mechanism and
thereafter turning it so that it faces in the original position
for presentation to the distributing mechanism.

No. 16747.—5th August, 1903.—HENRY MANNING, of 46,
Gray’s Inn Road, London, England, Engineer. Improve-
ments in and connected with lock-stitch sewing-machines.

Claim.—(1.) In a lock-stitch sewing-machine, the combina-
tion of a needle-bar working in vertical guides clear of and
below the work-plate, and having its upper end cranked to
extend over the work-plate and to hold the needle and take-
up device; a cam for operating the needle-bar, attached
thereto below the level of the work-plate ; a shuttle-carrier con-
sisting of a lever mounted to rock about a horizontal axis at
the lower part of the machine-frame, provided with cam-
surfaces whereby it may be operated, and having at its upper
part a cradle adapted to carry and permit the shuttle to slide
freely in contact with the shuttle-race ; a presser-foot ser-
rated to serve also as a means for feeding the work ; a lever
for carrying and operating the same, mounted to vibrate
clear of the work-plate about and transversely of the shuttle-
carrier axis, said lever being provided with cam-surfaces
whereby it may be operated, and having its upper end, which
carries the presser-foot, cranked to extend over the work-
plate ; a horizontal driving-shaft mounted beneath the work-
plate ; a disc fast on said shaft ; cam-studs carried by said
disc for operating the needle-bar cam and the presser-

foot lever respectively ; and a cam on said shaft for operating
the shuttle-carrier ; substantially as specified. (2.) In a lock-
stitch sewing-machine of the kind specified, the combination
with a rocking lever having a cradle for holding the shuttle,
of a spring-pressed latch adapted to normally close the rear
opening of the cradle and to be retracted to permit the inser-
tion and withdrawal of the shuttle, substantially as de-
scribed. (3.) In a lock-stitch sewing-machine of the kind
specified, the combination with a vertically reciprocating
needle-bar having its upper end cranked to extend over the
work-plate and provided at its lateral extremity with means
for holding the needle, of a take-up device for the needle
thread consisting of a spring arm attached at one end to the
needle-bar and provided at its free end with a loop for the
passage of the thread-bight formed between guide eyes on
the needle-bar, as specified. (4.) In a lock-stitch sewing-
machine of the kind specified. a spool-winding device consist-
ing of a U-shaped spring frame whereof one limb is pivotally
attached to the machine-frame and the other has a bearing
for one of the spool pivots, and a spindle journalled in said
frame and provided with spool driving and supporting means
and having fast on it a pulley adapted to be frictionally
driven from the main shaft of the machine, the U-shaped
frame being adapted to be removably locked in the operative
position by being sprung over a fixed projection on the
machine-frame, as specified. (5.) In a lock-stitch sewing-
machine of the kind specified, a folding crank-handle for
driving the machine, so placed angularly of the driving-shaft
as to act as a counterpoise to the other moving parts of the
machine so as, when free, to maintain the needle in con-
venient position for threading, as described. (6.) The em-
ployment for actuating the sewing-mechanism proper of a
sewing-machine, of independent portable treadle-operated
driving-gear whereof the frame is provided with a sole-plate
adapted to be held by the foot of the operator or of the
table supporting the sewing-mechanism, and with a clamp-
ing-device for adjustably securing the driving-gear to the
leg of the table, as described.
