Improvements in Sewing Machines,
I, CHARLES MADISON HINE, Inventor, of Eagle Power Building, Sandusky
Street City of Allegheny, in the County of Allegheny, and State of Pennsylvania,
U.S.A. do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
My invention relates to an improvement in sewing machines and it consists in
the arrangement and combination of parts that will be more fully described
hereinafter, whereby a remarkably rapid, cheap, and simple machine is produced.
The objects of my invention are to produce a sewing machine by means of which
an enormously high rate of speed can be obtained, and which is especially adapted
for sewing edge seams; in which the cost of maintainance is very small; the
adjustments quickly made; the parts easily repaired should they get out of order;
and the connections direct, and in their simplest forms.
In the drawings:
:-
Fig. 1 is a perspective of a sewing machine which embodies my invention.
Fig. 2 is a side elevation of the same.
Fig. 3 is an end view.
In the construction shown, 1 is a base of any suitable construction, and from
which rises the two bearings 2 in which the main shaft 3 is journalled. Extending
horizontally from this base is the bearing 4, through the outer end of which extends
the stationary rod 5, which is parallel with the main shaft, but in a lower plane.
For convenience of construction the rod 5 is secured to the extension 4 by a set
screw 6, but the parts may be made in one casting if desired.
Pivotted upon said rod by conical screws 7, 7, and jamb nuts 8, 8, is a yoke 9,
having a slotted upward projection 10, to which is attached an eccentric rod 11, by
means of a stud 12, and a nut 13.
This eccentric rod 11, embraces with its strap 14, a feed eccentric on main
shaft 3, for the purpose of vibrating backward and forward the feed yoke 9. The
feed eccentric in the present instance is fastened to the main shaft 3, by an extended
collar 15, and screw 16, but numerous modifications of such attachment will readily
occur to a skilled mechanic. The feed yoke 9, carries another shaft 17 parallel to
and above shaft 5. Spanning this shaft 17, is the needle carrying arm 18, pivotted
by conical screws 19, and jamb nuts 20 to the shaft 17. The needle carrying arm 18
extends forward to the line of the main shaft, and then takes an upward turn.
Pivotally fastened to the upper portion of said needle carrying arm by stud 21,
and nut 22, is a connecting rod 23, embracing an eccentric 24, on the main shaft,
placed side by side with the feed eccentric.
These eccentrics may be made either separately or in one piece. At a point on
the needle carrying arm 18, slightly back of the line of the main shaft is an out-
wardly projecting L-shaped piece 25, to which the needle 26 is secured in any
suitable manner.
A spur or false needle 39 is secured back of the sewing needle
in any suitable manner to the needle carrying arm. This false needle entering the
cloth takes the strain off the needle by helping to advance the cloth. The cloth
plate 27 is fastened to the forward bearing of the main shaft. Fastened to this
cloth plate 27 is a bracket 28, to support a flat leafed pressure spring 29. The loop
forming mechanism can be such as is here shown at 30, or of any other suitable
construction, and upon which my invention is in no wise dependent. The tension 31,
may also be of any desired construction, and with which my invention does not
deal.
The spool 32, may be set on a spindle 33, on the rear bearing 2, of the main

page_text: shaft, and to avoid snapping the thread it is led up through the perforated L-shaped
standard 34, on the same bearing. After passing the tension 31, the thread passes
to the needle 26, through a perforation in the stud 21, and the needle fastening.
At the rear end of the main shaft is a balance wheel 35, with groove 36 to receive a
driving belt. By merely sliding the stud 12 up and down in the slotted pro-
jection 10, the length of the stitch can be regulated at will. The slot may be
omitted, but in that case only one length of stitch can be used. The lateral
adjustments of the needle are made with equal ease by means of the conical screws
and jamb nuts on the ends of the shafts 5 and 17. Compensation for wear can also
be effected in the same way. In operation, the eccentric 24, transmitting motion to
the needle carrying arm, raises and lowers the needle. The feed eccentric by means
of its eccentric rod transmits motion to the slotted projection on the yoke, to which
yoke said needle carrying arm is pivoted by conical screws.
Since the feed eccentric is set diametrically opposite to the eccentric 24, the
following order of action takes place :-
The action of the large eccentric 24, draws the needle down through the cloth,
and while the needle is still in the cloth, the action of the small eccentric draws the
cloth forward. The action of the large eccentric now raises the needle and while
raised, the action of the small eccentric moves back the needle into position for the
next stitch.
The machine is almost indestructible, but if injured is readily repaired by an
ordinary mechanic without special tools. It is compact, cheap, direct acting, and
wonderfully fast. All bearings needing oil are protected by oil guards, so that the
operator will never injure the fabrics being sewed by having them come in contact
with the oil. Since the feed operates while the needle is thrust through both
pieces of cloth, both upper and lower pieces will be advanced evenly and together.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In an organized sewing machine, the combination of the following parts: a
driving shaft, an eccentric upon said shaft, an eccentric rod whose lower end
embraces said eccentric, a needle carrying arm whose forward end is pivotally
secured to the upper end of the eccentric rod, a feed mechanism suitably connected
with the rear end of said needle carrying arm, and a needle, substantially as set
forth.
2. In a sewing machine, a driving shaft, two eccentrics secured to the said shaft
