P. J, CLEVER, OF GOLIAD, TEXAS.
IMPROVEMENT IN SEWING-MACHINES.
Specification forming part of Letters Patent No. 96,881;, dated November 1li, 189; Reissue No. 3,776, dated
December 2S, 1869.To all w2hom it may conCern:
Beit known that I, P. J. CLEVER, of Golind,
in the county of Goliad and State of Texas,
have invented a new Improved Sewing-Ma-
chine; and I do hereby declare that the tol-
lowing 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 theaccompanying drawings, form-
ing part of this specification.
This invention relates to improvements in
sewing-machines, and has for its object to pro-
vide more useful and efficient machines than
those now in use.
The invention consists in the combination
and arrangement of the operating devices, as
hereinafter described.
Figure 1 represents a longitudinal sectional
elevationof my improved machine. Fig. 2rep-
resents a transverse sectional elevation taken
on lines x x of Fig. 1. Fig. 3 is a detail show-
ing a side elevation of the devices for operat-
ing the feed device and arranged to feed in
either of two directions. Fig. 4 is an eleva-
tion of the same at right angles to the eleva-
tion of Fig. 3 and partly sectioned. Fig. 5 is
a detail showing the shattle and shuttle-car-
r3ing arm and the connecting-rod for operat-
ing it. Fig. 6 is a plan view of the feed-shoe.
Fig. 7 is a detail showing the arrangement
for throwing the friction driving-wheel into or
out of gear with the friction-wheel on the
crank-shaft. Fig. S is a front elevation of the
tension device. Fig. 9 is a detail showing the
arrangement of devices introduced between
the crank-shaft and the needle-aria for work-
ing the latter; and Fig. 10 is a sectional ele-
vation of the needle-arm and cloth-presser
support, showing the arrangement of the nee-
dle-arm and tension-spring.
Similar letters of reference indicate corre-
sponding pants.
The treadle A has semicircular recesses to
fit the rods of frame A', and it is held in posi-
tion to be operated by a lever, A', having a
curved recess at one end, A3, that fits the rod
of said frame under the recesses of the treadle,
and at the other end the lever is provided
with atur b ntton,which, after passing through
a slot in the treadle, is turned transversely
thereof to lock the clamping-lever.The treadle is connected to a lever-arm, A6,
by a connecting-rod, which rod is wrist jointed
to both said treadle and lever-arm, as plainly
shown in Figs. 1, 2. This arm is fixed to a
shaft, A,, rocking on points screwed in frame
A'. The other end of said arm is at A'
wrist-jointed to a connecting-rod, A3, and this
rod is also wrist jointed to a crank of crank-
shaft A]. All this construction and arrange-
ment has for its purpose that the treadle may
be unlocked by the turn-button and loosened
by the clamp, so that it may be raised at the
rear from its frame and turned on a wrist joint
to either side or one end, to be fastened and
locked again on said frame, so that the machine
may be worked at either side or end of the
table.
The connecting-rod A' is slotted at its ends,
forming open spring-like ends, which tit and
are closed by screws on the ball-shaped end of
the lever-arm A' and the crank of crank-shaft
Ai', and, owing to this construction, the joints
may be adjusted to compensate for wear.
The crank-shaft A0, on which is mounted a
friction driving-wheel, A", turns on adjusta-
ble bearings or points held by set-screws in
frame B, hinged at one end, B', within the ta-
ble-frame, and at the opposite side said frame
is capable of rising and thlling, and has a fixed
bar, B, resting on an eccentric plate, B3, piv-
oted to a haiiner, B', secured to a bar, B', fixed
within the table-frame and provided at its up-
per end with a screw and nut for adjusting the
height of the hanger.
The plate B3 Is provided with a cam and a
handle for turning it, and so that a movement
in one direction will raise and the other lower
the frame B, so that the driving-wheel and fric-
tion-wheel B' are thrown in or out of contact.
When the frame is down the driving-wheel
may be revolved without giving motion to the
other parts.
Under the bar B' is a spring, B'' bearing on
bar B', fixed to frame B, to give a downward
pressure to the frame.
The friction-wheel B7 is constructed of a me-
tallic box, fittingloosely oncrank-shaftB'. This
box has one fixed round metallic plate at one
end and near the other end a similar plate fit-
ting loosely on it, and at the end it is provided
with a screw-thread and nut. One or more
