Letters Patent No. 96,886, dated November 16, 1869.
IMPROVEMENT IN SEWING-IMAC INE.
The Schedule referred to in thase Lettern Patent and making part of the same.To all whom it may concern:
Be it known that I, P. J. OtEVER, of Goliad, in
the county of Goliad, and State of Texas, have in-
vented a new and improved Sewing-Machine; and I
do hereby declare that the following is a full, clear, and
exact description thereof, which will enable others
skilled in the art to make and use the same, reference
being had to the accompanying drawings, forming part
of this specification.
This invention relates to improvements in sewing-
machines, and has for its object to.provide more use-
ful and efficient machines than those now in use.
The invention consists in the combination and ar-
rangement of the operating-devices, as hereinafter de-
scribed.
Figure 1 represents a longitudinal sectional eleva-
tion of my improved machine;
Figure 2 represents a t;ransuvese sectional elevation,
taken on the line x x of fig. 1;
Figure 3 is a detail, showing a side elevation of the
devices bfor operating the feed-device, and arranged to
feed in either of two directions;
Figure 4 is an elevation of the same-at fightangles
to the elevation of fig. 3, and partly sectioned;
Figure 5 is a detail, showing the shuttle and shuttle-
carrying arm, and the crank and connecting-roed for
operating it;
Figure ii is a plan vieAr of the- feed-shoe ;
Figure 7 is a detail, showing the arrangement for
throwing the friction driving-wheel into -gear or out
of gear with the friction-wheel on the crank-shaft;
Figunie 8 is a fiont elevation of the tension-device;
Figure 9 is a detail, showing the arrangement of
devices introduced between the crank-shaft and the
needle-arm for working the latter; and
Figure 10 is a sectional elevation of the needle-arm
and cloth-presser support, showing the arrangement
of the needle-arm and tension-spring.
Similar letters of reference indicate corresponding
parts.
The treadle A is mounted adjustable on a fame,
A', capable of supporting it in the same relative posi-
tion to either side of the table, so that it may be
changed fiomn side to side, or to one end, as maybe
required in working the machine for feeding either
way. It is connected to tile rods Qf the said frame by a
clamp, A', having curved recesses in the ends A', tak-
ing ulder the rod of the frame A'r and fitting the
curvature thereof. Above this curvatnure it rests oni a
fulcrum, A', and at the other end it is provided with
a turn-button, which, after passing through a slot in
the treadle, is turned transversely thereof and locked
above the rod. The treadle is also provided with -a
semicircular recess, fitting and oscillating on it.
The treadle is jointed to a lever, A', pivoted at A',and connected to the lower end of a connecting-rod,
A', at A'.
This rod A' is-connected to a crank-shaft, Ad, where-
on is mounted a friction driving-wheel, A1.
The shaft A" is mounted on a frame, B, hinged at
B' to the side of the frame, and connected at the other
end, on the opposite side of the machine, to a har, B',
capable of rising and falling, and arranged above a
cain-dog, B', arranged on an axle, and provided with
a handle for turning it, to raise or lower it, and above
the frame may be placed a spring, B, as seen in de-
tail in fig. 7, Sheet II of drawings, for pressing it
down.
The cam-dog is suspended by a hanger, B', from a
bar, B', fixed to the side of the frame, and the spring
B13, when used, is arranged .under this bar.
By turning this earnu-dog into the position repre-
sented in fig. 7, the fritie B will be raised, carrying
the wheel A" up into contact with the friction-wheel
B', on the crank-shaft B', arranged under the table,
parallel with the needle-armn support, and in the beai-
ings B' and B1r,
This wheel B' clutches with a ratchet-clutch, B",
connected to the shaft, so as to impart rotary motion
to it, but capable of sliding on it to and from the when",
and provided with a spring, B", to keep it up against
the clutch on the wheel.
This arrangement is provided, so that if the driving-
wheel is turned the wrong way, the clutches will slip,
and will not turn the crank-shaft.
B" is a balance-wheel on a crank-shaft, and B2i a
friction-brake lever, pivoted at B", and provided with
a rod, B11, rising up to the under side of the table,
through which a finger-stud, B", with a socket in the
bottom for the reception of the upper end of the rod
B"M, works, so that the operator may bring the brake
into contact with the wheel at any time, by pressing
down thereon.
This connection with the rod B" is made to admit
of raising the table, which is hinged at one side when
required.
A jointed brace, B", and sleeve, B", are provided
for holding the table when raised up. The ends of the
jointed brace lap at the joint, and assume the same
line when the table is raised up, so that the sleeve
slides on the lapped ends, and holds them from turu-
ing back.
The crank c of the shaft BI is connected, by a con-
necting-lrod, c', with a diamond-shaped plate, c ,
mounted on a rock-shaft, c, and a connecting-rod, c',
connects this plate with the needle-arnm 0.
The connection of the rod a' with the ivrist-pin of
tihe plate 0 is made by means of a double joint, so ar-
ranged that the rod may have oscillation in directions
perpendicular to each other.nilitid States (ltent Offits.
