ALFRED GEORGE BROOKES of N° 59. Chancery Lane, London in the County of
Middlesex Patent Agent. IMPROVEMENTS IN SEWING MACHINERY (Communicated
to me from Abroad by Robert Whitehill of the City and State of New York in
the United States of America)
This invention is an improvement on the class of Sewing Machine represented
in British Patent N° 3143. October 23. 1872.
In the said Patent the centre of the needle bar operating crank pin of the
plannet shaft is shown as located in the plane of the pitch line of the gear attached
to the said shaft.
The location of the crank pin as shown in the said Patent fails to afford as
much dwell as is desirable when the shuttle is passing through the loop of needle
thread.
To increase the dwell of the needle at the end of its downward stroke to afford
more time for the passage of the shuttle through the loop of needle thread, and at
the same time enable the use of a longer shuttle than heretofore used in the class
of machine referred to, and also to impart as short a stroke as possible to the
needle bar, I have arranged the said crank pin so that it has a greater throw and
I have placed the centre line of the said crank pin farther from the centre of the
plannet shaft, than the pitch line of the gear thereon, and such location of the
said crank pin constitutes one part of this present invention.
My invention also consists in a split bushing inserted therein and a plannet
shaft placed in the said bushing combined with screws to close the said bushing
upon the said shaft, one of the said screws having a teat to positively engage and
thereby prevent the longitudinal movement of the bushing.

mounted on the treadle stand. Figure 20 a section of the stand on the dotted
line Figure 19 and Figures 21 and 22 are details showing the ball like end of
the shaft of the treadle stand and its adjustable supporting box.
The framework A of usual shape has a main shaft A' provided at one end with
a fixed band-wheel A' and at its other end with the plannet hub A³ which carries
the plannet shaft A+.
The plannet shaft A has its bearing in a split bushing a placed in a passage in
the plannet hub and the said hub has two adjusting screws a¹, a to bear by their
ends against the said split bushing as shown in Figure 6 to force the bushing
closely in contact with the plannet shaft, and one of the said screws, the one, marked
a¹ has a teat to enter a hole of corresponding size in the said bushing to prevent the
bushing moving longitudinally and from rotating.
The plannet gear a is attached to the plannet shaft by a screw 4 after the same
has been inserted through the plannet-hub and split bushing, and the said bushing
is made longer than the said hub so that the crank and gear on the plannet shaft
may rest against opposite ends of the said bushing.
The plannet shaft crank or disc 16 at its other or outer end, is provided with a
needle bar actuating crank pin a³ the centre line of which it will be noticed in
Figure 6 is at a greater distance from the centre of the plannet shaft than the pitch
line of the teeth of the planet gear at such location of the said crank pin beyond
the arc described by the pitch line of the teeth of the said gear enabling me to give
to the needle bar a and its attached needle a³ a longer period of rest at the end of
its downward stroke, whereby the shuttle which carries the usual under thread is
allowed more time to enter and pass through the loop of needle thread than were
the centre line of the said crank pin only at the level of the pitch line of the
plannet gear thereon as in the Patent referred to.
By placing the crank pin further from the centre of the plannet shaft than the
pitch line of the gear on the said shaft which engages the stationary sun gear B it
is possible to produce a longer dwell in, the needle bar when at the end of its
descent.
The greater the dwell when the needle bar and needle are in their lowest
position the longer the time for the shuttle to enter and pass through the loop of
needle thread, and the longer may be the shuttle
Attached to the crank pin a is the connecting rod 61 having its lower end as
herein shown enlarged to form a head be shown clearly in Figures 3 and 10 the
said head having its edges entered in to grooves of guide ways formed in the
head A of the machine
The edges of the said head 6' are shown as made V-shaped and one of the
V-shaped grooves in which the said head is moved is formed in a yielding part or
wing 63 of the machine head
Viewing Figure 1. it will be seen that the part b³ referred to is separated from
the main part of the arm head by the slot 6' and in Figure 10 it will be noticed
that the said part 6ª is cast with a curve, a core having been used, leaving an open

page_text: space 65 which permits the said part 6ª to be sprung or moved, as a lever by
suitable screws.
The screw be passed through the part 63 or adjustable wing of the guide way and
screwed into the arm head as shown best in Figure 10 enables the said wing to be
forced inward to fit the head b³ closely.
The screws b' one above and the other below the screw be and having their ends
placed against the fixed part of the arm head while their threaded shanks engage
screw threads in the wing are employed to force the wing away from the fixed part
of the arm head, and by the employment of the said screws 6º 67 adapted to operate
upon and move the said wing in opposite directions positively, the said wing may
be adjusted so.that its inner grooved face will occupy a position parallel with the
inner face of the opposite or fixed part of the said guide way in which the head b²
is reciprocated.
This head b³ forming part of the connecting rod b¹ has a stud c which is extended
loosely through the needle bar a and the upper end of the needle bar is extended
into the guide c' which is the only fixed guide employed for the said bar.
A needle bar held and reciprocated in this manner is not subjected to other than
longitudinal strain and consequently may be made smaller in diameter and by the
employment of but one fixed guide it is possible to shorten the length of the needle
bar thus reducing its weight and momentum.
The sun gear B. is fastened to the arm or framework A by a screw 18 see
Figure 5 and made as a sleeve the said sun gear forms one bearing for the main
shaft A¹,
The needle bar, at one side, is provided with a series of teeth forming a rack as
shown in Figures 1 and 3 to engage the teeth of and reciprocate the take-up gear c³
mounted on a stud 2 inserted in a carrier c³ pivoted on a fixed part of the arm
head and the said carrier is moved or adjusted by the screw c³ in order to ensure
the proper ineshing of the said gear and rack. The take up lever or arm c is
attached to this gear c² and operates as in my former Patent.
The needle bar is split at its lower end for a short distance upward, its extremo
end is tapered at 19. and above its tapered portion its cylindrical but reduced end
is provided with screw threads to receive a screw threaded nut c' having a tapering
inner surface at its lower end to act against the tapering ends 19 of the split bar
and cause the said ends to close upon and grasp the shank of the needle a
inserted into a longitudinal hole in the needle bar, and hold the needle firmly in
place.
The upper end of the needle shank is notched or shouldered as at 5, Figure 4, to
form a flat surface 21 against which acts the ends of the needle adjusting screw d
to hold the needle in such position that the axis of its eye will point in the proper
direction.
The vertical position of the eye of the needle, or its distance from the end of
the needle bar, is determined by the end of the needlo shank striking the end of
the longitudinal passage in which it is inserted see Figure 4
The main shaft A has a bevel gear c which engages a bevil gear C¹ on an
upright shaft C2 provided at its lower end with a balanced crank C³ of usual
construction it having a crank pin C on which is placed the shuttle moving
pitman C having a disc co, see Figures 3 and 11 attached to its other end by
screws 7 but if desired the said disc may be made as an integral part thereof
The disc having its edges bevilled as herein shown is fitted to guide ways in the
walls d d forming the race way for the shuttle carrier d²
The wall d¹ is acted upon by adjusting devices d³ shown as screws, which keep
the said walls and the edges of the said disc in proper contact and afford means to
take up any wear between them.
As the disc c becomes worn the screws 7 may be taken out and the disc be
turned partially around to present a new or unworn surface in the said grooves
when the said screws will be again inserted but this time in other holes 8 therein
see Figure 11.

page_text: The disc oscillates somewhat as it slides in the guide ways of the walls dd.
The shuttle carrier d² has a stem d which is inserted locsely into a hole made
through a hub rising from the upper side of the disc at its centre, see Figure 3 and
below the said disc the said stem has applied to it a collar d³ which is attached
thereto by a set screw 12.
The shuttle carrier d³ travels in a straight line in its race and as it is so moved
its disc c oscillates on the said stem. The carrier d³ has straight edges 22 which
bear against the back wall of the shuttle race, and to compensate for wear at such
point I may if desired provide the said back wall with a gib. The band wheel e
placed directly on the main shaft A¹, is held thereto by a radial stud e¹ carried by
the said shaft the said stud having its lower end bevilled to rest upon a corre-
spondingly bevilled notch e in a longitudinally adjustable screw or rod e² placed
in a longitudinal opening drilled into the main shaft as best shown in Figure 1,
the said screw or rod having upon it a nut e³ the end of which jams against the end
of the main shaft so that rotation of the said nut enables the said screw to be
moved longitudinally.
When drawn outward the bevilled surface of the screw or rod acting against the
bevel of the stud c¹ forces the latter out in contact with and holds the band wheel
securely upon the said shaft, and the force exerted by the stud to hold the band
wheel in place is directly at right angles to the shaft, and a plane intersecting the
axial centre of the hub of the band wheel, thus enabling the latter to be drawn
squarely to the shaft.
The combination of the bevilled notch et in the screw rod e² and the bevilled
stud e¹ as shown effects the prevention of displacement or loss of the parts, since
the notch is always in engagement with the stud and the two can only be
disconnected by the removal of the band wheel.
The band wheel being placed directly upon the main shaft rather than upon a
hub of the band wheel will, when loosened, run more easily on and with less
liability of turning the said shaft with it.
The upright shaft c³ has upon it, above the crank c³ a single eccentric ** which
is embraced by an eccentric strap of the feed lever ƒ but herein, instead of pro-
viding the said lever with a crook or compound cam for imparting the vertical and
forward movement to the feed dog as has been done, the said lever has joined to
its end by the screw 13, an independent crooked part f¹ preferably made from
steel.
The part f¹ having the said crook being a separate piece attached to the said
lever by a screw 13. enables one by a mere change of the portion f' to effectually
renew the feed lever
This feed lever reciprocates in a guide block f³ swivelled in one arm of a swivel
lever pivotted to the bed at f¹, another arm or part of the said swivel lever
having a pin or stud 14 which enters a diagonal slot or groove 15 in a stitch
regulating bar f³ or vice-versa fitted at its end to suitable guide ways and having
connected with it a thumb nut fo by which to adjust the said bar longitudinally
according to the length of stitch desired, and to fasten the said bar in place
The swivel lever as it is turned moves the guide block f laterally instead of
longitudinally as similar swivel blocks have heretofore been moved
It is a great desideratum to ensure the backward movement of the feed bar
always to a certain point for all lengths of stitch, and to move the feed bar or
device forward from such established point the distance desired for the stitch to be
made and by moving the guide block laterally instead of longitudinally it is
possible to accomplish the desired object.
Longitudinal change of position of this guide-block changes the fulcrum of the
lever with relation to its actuating eccentric, and consequently the backward
position of the feed bar varies at each variation of length of stitch
The under-side of the feed bar or device h has attached to it by screw ' a small
plate which bears against the under side of the crooked part fi of the feed lever,
thus obviating.the formation of a completely walled slot in the said feed bar

page_text: The single eccentric & referred to operates the feed lever and its crooked end f¹
so as to produce both the upward forward and downward motions of the feed bar,
a spring t producing the backward movement.
The presser foot m carried by the presser bar m¹ is pressed down by an
adjustable spring m³ and may be lifted by the lever m³.
Oil used in the arm head of the machine will be caught in the drip cup n
attached thereto by the screws n¹
The needle thread is led from the tension device over the sheaves o o' and
through the wiro eye o² to the eye of the needle
The thread guides containing the sheaves o o¹ are of peculiar construction as 1
will now be described
The frame part of each of the said guides is composed of a piece of sheet metal
cut to form the blank shown in Figure 3.
This blank has at one side near one
end the depression n to receive one end of the sheave as represented in Figure G
so that the end of the sheave terminates in a plaue back of the surrounding part 1
of the frame part to obviate the passage of thread between the sheave and
frame part
The blank at its left hand end as in Figure 6 has a holo p² a slot p³ and a
projection p. The metal of the blank about the hole p² when the blank is folded
as shown surrounds the outer end of the sheave as in Figures 1. 2 and 9
The projection 2 is bent at right angles to the main part of the blank and when
the blank is folded the said projection extends to the opposite side of the blank
under the sheave as in Figure 9.
The slot serves for the passage of the thread about the sheave.
In the manufacture of the Sewing Machine herein described the bed is planed
to form guides for the stitch regulating device f" and bored to receive the stud f*
and the bearings for the shaft c³ are also bored, so these points are established when
the swivel lever is put in place. To enable the pins 14 and the connecting pin 24
to be adjusted exactly into position to time the feed, the swivel lever is split as
at 26 and made to present two arms, and to these arms are added an adjusting
screw 25 by which the arms of the swivel lever may be moved toward and from
each other, such adjustment of the lever permitting wear of the feed bar with the
part of the feed lever to be compensated for so that the feed may always be
started at just the proper time with relation to the movement of the other parts of
the machine.
The side pieces B³ of the stand, of usual shape, are connected by a suitable brace
or cross piece B*, screws 30 holding the same together.
The lower ends of the side pieces are joined as usual by the treadle rod 31. The
band wheel 32 is attached to the band wheel shaft 33. it having as herein shown
at one end a ball-like journal portion 34 best shown separately and enlarged in
Figures 21 and 22 where is also shown one of the two halves 35 of the divided
bearing 35, 36 shaped to receive and fit the said ball like journal.
The two parts 35. 36 of the said bearing are fitted into a suitable recess in the
side piece B³, and are held in place by the set screw 37 which as herein shown
bears against the outside of the part 36 of the bearing the part 36 by its pressure
against 35 holding the latter in adjusted position.
By moving the parts 35. 36 of the bearing longitudinally with relation to each
other in opposite directions the said bearing may always be kept pressed firmly
against the ball like journal and wear between the said parts may be readily
compensated for.
The said shaft near its opposite end inside its attached crank 38, is supported in
a bearing 39. split from its front end backward past its centre as best shown at 40
Figure 20, the said bearing having an adjusting screw 41. by which to draw its
upper and lower parts together to thus fit the shaft 33. the latter when inserted
therein fitting loosely
The ball-like journal 34 enables the shaft 33 to be run smoothly and steadily

page_text: even though the bearings for the said shaft should be out of line, and also obviates
loss of time in fitting the shaft to its bearings.
The treadle or foot piece 42 is connected by link 43 with the crank pin 44 of
the shaft 33.
The brace or cross-piece B* has an attached dress shield. 46.
Both sides of the bearing 39 may be countersunk in line with its shaft receiving
opening to reduce the length of the bearing portion of the same and aid in
alligning the shaft 33.
The shuttle body or shell 45 open at its heel as usual, has connected with it by
a tension adjusting screw 46, a spring metal plate 47 forming a combined tension-
spring latch and bearing cap.
The part 48 of this piece of spring metal has a prong 49 to enter a hole 50 in the
shuttle shell and serves as the latch
The tension spring is composed of the narrow strip 51 and the finger 52 they
forming part of the main portion 49. and the cap or bearing 53 is connected with
and forms an extension of the part 47.
The front end of part 47 is depressed to form a seat for the head of the screw 46.
The front end 54 of plate 47 bears on the shuttle body or shell as in Figure 15
which latter serves as the fulcrum to hold the plate 47 while the screw 46 is turned
to act upon the said plate and cause the tension spring to bear with more or less
force upon the thread led from the bobbin in the shell out through the slot 55 over
the finger 52 under the spring and about the prong 56 formed by slotting the shell
from the holes 57 and thence the said thread passes out through the slot 58 and as
the shuttle is reciprocated the shuttle thread is made to slide over the convexed
rear edge of the plate 47 in the slot 58
The bearing cap 53. has an ear 60 to enter a notch in the heel of the shuttle
shell
The longitudinally moveable tension adjusting screw 46 has its shank reduced
near the centre of its length to receive the point or end of a set screw 61 to hold
the adjusting screw in place, see Figure 17.
The plate 47 with its integral parts, as described, to bear upon the thread as a
spring and to act as a latch and to serve as a cap for the heel of the shuttle shell,
is struck up from thin sheet metal and occupies much less space than were the
tension regulating spring attached as an independent piece to a rigid armı pivoted
upon the shuttle shell.
The slot in the plate 47 for the screw 46 is shown elongated in order that the
said plate and its attached adjuncts may slide longitudinally on the shuttle
shell and also be tuned away laterally to uncover the heel of the shuttle as in
Figure 12
The cap 53, it will be noticed is a very thin plate of metal and it has a central
bole to receive the journal 64 of the bobbin 65 and being of thin metal it is
possible to employ a long bobbin.
The journals 64 are shouldered at 67 just outside the heads of the bobbin to
