PROVEMENTS IN SEWING MACHINES AND THEIR ACCESSORIES." A communication
to me from abroad by Roswell Heazeltine St. John, of Springfield, in the County of
Clark, and State of Ohio, in the United States of America.
This sewing machine is of the class known as lock-stitch machines having a
reciprocating needle, a reciprocating or oscillating shuttle, and a four-motion feed
and a take-up; it is adapted to feed and sew in one and the same direction, while
the main driving shaft is rotated in either direction. The take-up is operated
independently of the needle bar in such a manner as to give the necessary slack
to the thread to permit the passage of the shuttle without arresting or varying the
motion of the needle, and the take-up cam is so mounted on the driving shaft that
it will automatically receive its proper position relatively to the other parts to
operate with the same effect when the motion of the shaft is reversed. The crank
slide and cross head, by which motion is communicated from the rotary shaft to the
reciprocating needle bar are divided and adjusted by a set screw to compensate for
wear. The vertical transmitting lever operates the oscillating shuttle and feed
driver through the medium of a spherical head adjustable to regulate the throw of
the shuttle. The shuttle race is lined in part with raw hide to lessen wear,
friction, and noise, and is provided with depressions or slots to permit the escape
of dust.
The Invention further relates to what are termed reciprocating shuttles, and
particularly to those shuttles which are cylindrical in general shape, the bobbin

piece.
This part of the Invention consists in a latch which is hinged permanently to
the exterior at one end of the shuttle case, and is adapted to move in a plane per-
pendicular to the surface to which it is applied.
The Invention consists further in the provision of a series of tension pins in
combination with a latch having perforations to permit it to receive the ends of the
said pins, and also keep the thread in place.
The Invention consists further in a latch having a bevilled heel piece forming a
door to the bobbin receptacle.
The Invention further consists in mounting a driving or band wheel in a moveable
bearing frame or lever, so that the depression of the said wheel or the gravity of
the parts may be made to tighten the band as required.
The Invention further consists in so combining a band wheel running in moveable
bearings and a friction pinion that the bearings of the band wheel may be moved in
one direction to cause the wheel to tighten and drive the band, or in another
direction to cause it to release the band, and to bear against and drive the friction
pinion to run a bobbin winder, needle sharpener, or other device.
The Invention further relates to wrist pins for the driving wheels of sewing
machines, and it consists in constructing a wrist pin with two conical bearings
adjustable relatively to each other, the outer bearing being attached to a screw bolt
passing longitudinally through the centre of the pin, and tightened as required by
means of a nut.
The Invention further consists in adapting a sewing machine cover to be sup-
ported in inverted position at the end or side of the table to serve as a receptacle
for work or as an extension of the table as desired.
The Invention further consists in constructing a sewing machine cover with one
side reversible, so as to bring the opening beneath the top of the cover when it is to
be used as a cover, or in lateral position to permit the cover to be used as an
extension of the table by supporting it at one end or side of the table by the use of
hooks, clips, or other suitable attachments.

PROVEMENTS IN SEWING MACHINES AND THEIR ACCESSORIES." (A communication
from abroad by Roswell Heazeltine St. John, of Springfield, in the County of Clark,
and State of Ohio, in the United States of America.)
This sewing machine is of the class known as lock-stitch machines; having a
reciprocating needle, a reciprocating or oscillating shuttle, and a four-motion feed
and a take-up; it is adapted to feed and sew in one and the same direction, while
the main driving shaft is rotated in either direction. The take-up is operated
independently of the needle bar in such a manner as to give the necessary slack
to the thread to permit the passage of the shuttle without arresting or varying the
motion of the needle, and the take-up can is so mounted on the driving shaft that
it will automatically receive its proper position relatively to the other parts to
operate with the same effect when the motion of the shaft is reversed. The crank
slide and cross head, by which motion is communicated from the rotary shaft to the
reciprocating needle bar, are divided and adjusted by a set screw to compensate for
wear. The vertical transmitting lever operates the oscillating shuttle and feed
driver through the medium of a spherical head adjustable to regulate the throw of

page_text: une shuttle. The shuttle race is lined in part with raw hide to lessen wear,
friction, and noise, and is provided with depressions or slots to permit the escapo
of dust.
The Invention further consists in mounting the driving or band wheel in a
moveable bearing frame or lever, so that the depression of the said wheel or the
gravity of the parts may be made to tighten the band as required.
The Invention further consists in so combining a band wheel running in movenblo
bearings and a frictional pinion that the bearings of the band wheel may be moved
in one direction to cause the wheel to tighten and drive the band, or in another
direction to cause it to release the band, and bear against and drive the friction
pinion to run a bobbin winder, needle sharpening or other device.
The Invention further consists in adapting a sewing machine cover to be sup-
ported in inverted position at the end or side of the table to serve as a receptaclo
for work or as an extension of the table, as desired.
The Invention further consists in constructing a sewing machine cover with one
side reversible, so as to bring the opening beneath the top of the cover when it is to
be used as a cover, or in lateral position to permit the cover to be used as an
extension of the table by supporting it at one end or side of the table by the use of
hooks, clips, or other suitable attachments.
The Invention further relates to a wrist piu for the driving wheel of a sewing
machine, and it consists in constructing a wrist pin with two conical bearings
adjustable relatively to each other, the outer bearing being attached to a screw bolt
passing longitudinally through the centre of the pin, and tightened as required by
means of a nut.
The Invention further relates to what are termed reciprocating shuttles, and
particularly to those shuttles which are cylindrical in general shape, the bobbin
being introduced at the rear end or heel of the shuttle, and confined by a heel
piece.
This part of the Invention consists in the construction of a cylindrical shuttlo
with lateral projections at its front end with which a point or toe of approved shape
is formed. The shuttle is adapted to run sinoothy and in a race of ordinary form
either straight or curved, and it is prevented from rolling out of position by its
lateral projections.
The Invention further consists in a latch, which is hinged to the exterior at one
end of the shuttle case.
The Invention further consists in the provision of tension pins in com-
bination with a latch having perforations to permit it to receive the ends of the
said pins.
The Invention further consists in a latch having a heel piece forming a door to
the bobbin receptacle.
And in order that the said Invention may be more clearly understood and readily
carried into effect I will proceed, aided by the accompanying Drawings, more fully
to describe the same.

Figures 11 to 18, inclusive, are on a smaller scale, and Figures 19 to 27 on a
larger scale than Figures 1 to 10.
The improved sewing machine, Figures 1 to 10, in the particular form represented
is constructed as follows:-A hollow arm 1, having the usual liead 8 and suitable
bearings and recesses, is erected on a flat cloth plate 16, having hinges 52 at one
edge for attaching it to the table in customary manner. A rotary driving shaft 19
is mounted longitudinally in the horizontal portion of the arm 1, and provided
behind the same with a grooved band pulley 2 and a fly wheel 3. Within the
head 8 this shaft carries a crank disc 4, and a collar 5 behind the same for operating
respectively the needle bar 14 and the take-up 20. The needle bar slides in central
vertical ways in the head, and a straight needle 40 is attached to its lower end,
and receives a simple reciprocating movement. The take-up 20 has a transverse
horizontal pivot at the back of the head 8, and works through a vertical slot in the
face plate of the head, having an eye 45 in front of the latter to receive the thread;
it has an oscillating movement independent of the motion of the needle bar, so as
to give the requisite rest or slack to the thread during the passage of the shuttle
without the needle resting. Within the head 8 a cross head 7, having a deep
horizontal groove 51 in its back, is formed on or attached to the needle bar to
receive a slide 50, which embraces the wrist pin of the crank disc 4.
The cross
head 7 is divided horizontally, and its lower part is east on the needle bar; its
upper part has a collar to embrace the needle bar, and is attached to the lower part
by a screw 49. The slide 50 is similarly divided, its two parts being held in position
relatively to each other by dowel pins, and by tightening the single screw 49 any
wear in either or both parts may be taken up, and the fit thus rendered as tight as
when the machine is new. The cam collar 5 is mounted loosely on the hub of the
crank disc so as to slide, and is attached thereto by a screw 48 occupying a
recess 47, which permits a limited movement of the collar, as illustrated in Figures 9
and 10; it operates the take-up through the medium of a gravitating vertical
slide 9, having a lateral pin at its upper end which traverses a slot in the head, and
occupies a longitudinal slot in the take-up lever. When the take-up is depressed,
as seen in Figure 1, the lower end of the slide occupies a slot or groove in the cam

page_text: A
collar, at each end of which groove is an incline connecting it with the prominent
cylindrical surface. The rear incline is stopped by the screw 48 in proper position
relatively to the crank disc to elevate the take-up at the proper movement, and the
other, following, lowers it at the proper movement. If the driving shaft be turned in
contrary direction the collar will be reversed by the free motion of the shaft
relatively to it, and will then operate in precisely the same manner, the incline,
which before served to lower the take-up serving now to lift it, and vice versa.
pressure foot G and tension discs 10 with appurtenances applied to the head S,
thread guides 33, 332, applied to the head and needle bar, a spool holder 34 applied
to the top of the arm, and a bobbin winder 23 applied to the cloth plate are repre-
sented as customary appurtenances, and these devices or their equivalents of any
preferred construction may be employed. Within the arm 1 at its elbow the
shaft 19 is provided with a crank wrist 29, which occupies a fork 32 at the upper
end of a vertical transmitting lever 12, the pivot of which is formed by a screw
rod 13 tapped into the vertical portion of the arm 1, and secured by a jam nut 37.
A fork 32 at the lower end of this lever embraces a pair of cheek plates 15 applied
to the ball-shaped head of a coupling screw 17, which is tapped into the rear end
of a horizontal lever 18, and is locked by a jam nut 43. Both ends of the lever 12
are split parallel to the forks, as represented in Figure 8 and transverse screws 38;
382, are tapped into the same as means for tightening the forks to take up wear. The
lever 18 has a pivot near its rear end formed by a vertical screw 13 in combination
with a jan nut 30 to lock the same, and with a hollow post 21 within which the
pivot is formed. In front of this pivot the lever is bifurcated, a main arm 44
extending within the shuttle race 25, and a second arm 44 extending laterally to
connect with a rod 22 by which the feed bar 24 is actuated. The shuttle carrying
arm 44 is extended into the shuttle race through a horizontal slot formed at the
top of the casting 25, which forms the bottoin of the shuttle race. A vertical
slot 27' is formed at the lower edge of the same for the escape of dust. The shuttle
carrier proper is adapted to the shuttle 45, which in the illustration is one of
peculiar construction, as herein-after described. By adjusting the ball-headed
screw 17 the throw of the shuttle is regulated. To reduce the friction, wear, and
noise within the shuttle race in a superior manner a single strip 27 of raw hide is
applied in a longitudinal undercut groove in the top of the casting 25¹, as shown in
Figure 1. The feed rod 22 is constructed, as represented in Figure 6, with a
straight rectangular portion 28 at its effective end, and terminates in an obliquo
end 30 forming lateral inclines 35, 352, and having also a higher bottom connected
to the bottom of the portion 28 by au incline 353 in the same line as the latter.
The feed bar 24, Figure 5, slides in ways formed on the under side of the plate 16,
and is supported and guided at its front end by a screw 41, Figures 2 and 4,
occupying a deep notch or horizontal slot 501, and furnished with a friction
spring 41, as shown in Figure 2. At its rear or inner end the feed bar is furnished
with a vertical notch 50 to receive the portion 28 of the rod 22, and it is pressed
downward upon the rod by a spring 45', Figure 4. The feeding dog 30' is attached
between studs 50 by a screw 35 occupying a vertical slot, which provides for
adjusting the dog in setting up the parts. The rod 22, extending through the
notch 50 in the feed bar, is supported at its outer end, on a vertical abutment 31
adjustible by means of a screw 36 in a hanger 10¹ formed on or attached to the
bottom of the cloth plate. The inclines 353 on the feed rod engages with this
abutment to raise and lower the dog, and the incline 35 engages with the rear
wall of the hanger to impart the retreating horizontal stroke. The main or feeding
stroke is imparted by the incline 35 operating in combination with an abutment 31
Figure 2, in the form of an eccentric adjustable by means of a hand lever 20, which
projects at the front edge of the cloth plate, and may be held by friction or by
incans of notches or other detents. The pivot of this lever is formed by a vertical
screw 363. The feed will be operated in the same manner relatively to the motions
of the shuttle and needle, whether the driving shaft turn forward or backward,
and provision being made for the automatic adjustment of the cam for operating

page_text: the take-up, as before described. This machine is adapted to feed in one direction,
and to sew perfectly with the driving shaft turning in either direction, which is the
primary object of this part of this Invention. At the same time provision is made
for taking up wear at every point. The operating parts are simple and compact,
and the changeable movements may all be readily regulated.
Referring to Figures 11 and 12, 53 represents a portion of a sewing machine table,
and 54, 54, portions of the supporting frame thereof; 55 is the treadle; 56 is the pitman
connected to a wrist 57 on the driving wheel 58 to rotate the said wheel; 59 is the
band which transmits rotary motion from the wheel 58 to the driving shaft 60.
The band wheel 58, instead of running in stationary bearings as is usual has its
bearings in a vertically moveable frame or lever G1 by which the said wheel may
be thrown up to cause it to bear against and drive a friction pulley 62 when
required, and in so doing to release the band 59, so that the sewing mechanism,
which is connected to the driving shaft 60 in any usual or suitable manner, will be
left at rest. The friction pulley 62 is connected with a bobbin winder, or may be
employed to run a needle sharpener, or any other appendage of a sewing machine
which it may be desirable to operate, while the sewing mechanism remains at rest.
The Drawings show the band wheel 58 elevated, so as not to drive the band 59,
but to drive the friction pulley 62 of the bobbin winder or other device. By
elevating the free end of the lever 61, as indicated by the curved dotted line in
Figure 11, the wheel 58 will be lowered out of contact with the pulley 62, and so
as to tighten and drive the band 59.
The Invention avoids the necessity of unbanding the machine in order to avoid
driving the sewing mechanism while operating the bobbin winder.
This part of the Invention is not limited to the specific device, herein shown, for
moving the wheel into operative connection with either the band or bobbin winder
at will, and out of such connection with the other.
Referring to Figures 13 to 18, 53 represents the top of a sewing machine table
of any suitable construction; 65 is a cover made of suitable dimensions to cover
and protect the mechanism of the sewing machine in the usual manner. One
side 66 of this cover is pivotted at its edge 67 to the end 64, 64, of the cover, so
that it may swing in the path indicated by the curved dotted line in Figure 14; this
swinging side constitutes one side of the cover when used as a cover, as illustrated
in dotted lines. 68 is a button pivotted at 68', and turning against a stop 70 to
hold the swinging side firmly in this position, the free edge of the swinging side being
thus clamped between the end of the button GS and the bead or shoulder 72 of the
cover top. When the cover is to be used in inverted position to form an extension
of the table, as shown in full lines, the swinging side is turned up to form the
top of the table extension, and is there held by the button 69, which is pivotted at
69, and turns against a stop pin 71, holding the free edge of the swinging side 66
firmly against the bevel or shoulder 73. Hooks 74 are attached to the end of the
table for the reception of eyes 75 fixed on the side of the cover, or if preferred
clips 76, shown in Figures 16, 17, and 18, may be used to hold the extension in its
position at the end of the table by means of screws 77 fixed on the cover side.
These clips are formed so as to converge toward the table end, as shown in Figure 16,
in order that they may exert a wedge-like force on the extension to force it firmly
against the end of the table; they are constructed with slots and enlarged openings
to receive the screw heads, and with notches at the termination of the slots, into
which the screws descend, so as to lock them in position. Other forms of fastenings
may be used if preferred.
Referring to Figures 19 to 21, 80 is the main body of the wrist pin, which is
made in tubular or hollow form with a conical bearing 81, and the customary
tenon 82 to be inserted in the driving wheel, and secured by a bolt 83. The
adjustable portion consists of a conical head 84 and a bolt 85, the latter passing
longitudinally through the hollow body 80 of the pin, and being threaded at its
end to receive a nut S6, the face of which bears against the extremity of the
tenon S2. The head 84 is preferably formed with a flange 87 lapping over the

page_text: extremity of the bearing 81, so as to cover the space which is left to permit the
adjustment of the parts. To prevent the bolt 85 from turning within the pin 80,
and avoid the possibility of the nut working loose, the bolt is provided with a pin 88
occupying a notch or slot 89 in the end of the bearing S1.
From the above description it will be manifest that after the pin has been secured
in the driving wheel, and the pitman or connecting rod applied to the wrist, any
wear of the latter causing it to work loose to the slightest extent may be com-
pensated by drawing in the bolt 85 by means of its nut S6, so as to cause the
conical head to slightly approach the bearing 81.
While describing the device as a wrist pin for crank wheels it is not desired to
limit the Invention to this particular application of the device; it can be used with
equal advantage as a stud, shaft, or journal for a wheel to run on.
A
Referring to Figures 22 to 27, 90 is the hollow body of a shuttle. The body is
cylindrical, and of sufficient size to accommodate an approved bobbin 91, which
latter may be of a common form with solid spindle. The rear end or heel 92 of the
shuttle body is open; its point or toe 93 is sharpened, and is furnished at bottom with
lateral projections 94, which aid in forming the point, and prevent the shuttle from
turning, so as to keep the right side to the needle, besides adding to the smooth
working of the shuttle, and adapting it to run in an ordinary race, either straight
or curved. A cup bearing for one end of the bobbin spindle is formed in the solid
point 93 of the shuttle. A bearing for its other end is formed in the centre of a
bevelled heel piece 95, by which the heel 92 is closed, and the bobbin secured.
latch 96 is hinged to the shuttle case at its front end, and to the outer end of this
latch the heel piece 95 is hinged, as most clearly illustrated in Figure 22, so that the
cap shall secure the latch, and the latter shall prevent the loss of the heel piece, while
permitting its removal from the shuttle to facilitate introducing and removing the
bobbin. The heel piece is made to fit tightly enough to prevent its accidental dis-
placement, and a notch 97 is provided in the shuttle body to admit the thumb nail
for opening the heel piece. The latch is perforated as represented, but not to
receive the thread. As a more convenient substitute for holes or notches as tension
devices a series of tension pius or studs 98 is applied to the needle side of the shuttle
body, and the said perforations in the latch receive the ends of these pins. A
longitudinal slot 99 is formed in the face of the shuttle extending from the heel to
these tension pins, and preferably beneath one or more of the latter, as represented
in Figure 26. A new bobbin having been introduced the retained outer end of the
thread is quickly drawn into this slot and around one or more of the pins for the
required tension. The latch and heel piece are then closed, and the bobbin is
ready for use. The hinges and other details of construction may be of the simplest
character.
The advantages gained by this improved construction of shuttles will be
apparent. The thread and tension can be got at in one and the same operation,
thereby saving time in getting the machine ready for work, while other shuttles
have to be threaded through holes or work screws. The threading, as is well known,
is a matter of great importance. This simple device meets the demand for a
quickly threaded shuttle."
