Sewing Machine Needle Turvauti.
I, PATRICK BRALLEY of No. 1939 Market Street, Oakland, Alameda County,
State of California, U.S.A. Barber, 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 a device for threading the needles of sewing machines.
It consists in certain details of construction which will be more fully explained by
reference to the accompanying drawings upon which :-
Figure 1 is a perspective view of my needle threader in position.
Figure 2 is a side view showing it turned up and held out of the way while the
needle is threaded.
Figure 3 is an enlarged perspective view of the needle threading block.
Figure 4 is a side view of the block, the two parts that form it being opened.
The object of my invention is to provide a device which is adjustable with
relation to the needle and needle-bar, so hinged that it may be turned up out of the
way when not in use, and readily turned down to clasp the needle, having a hole
through it which exactly coincides with the eye of the needle, and serves as a guide
to direct the thread through the eye, the device being made in two separable parts
which will open automatically by a little pull, to allow the device to be moved away,
leaving the needle and thread in position for use.
A is my needle threading block. It consists of two parts fitted accurately
together and having one end secured to a flat elastic steel plate B which normally
holds the two parts with their adjacent faces lying together like a single block.
Between these two, near the end opposite to the attachment B is made a tapering
hole or countersink C terminating in a very fine hole upon the opposite side, into
which the tapering portion guides the thread.
Upon the opposite side of the block is a vertical groove or channel D with a spring
plate E fixed to one side and extending over this groove or channel, so that wben
the device is properly adjusted, the needle lies in this groove or channel and is held
in place by the spring E, so that its eye is exactly in line with the hole C, and a
thread introduced into this hole, will be directed through the eye of the needle.
The threading device is then pulled to one side, the thread being held by the
hand, and by means of a little groove or channel F extending outward from the side
of the hole C and between the two pieces A, the thread is enabled to pass between
these plates and separate them enough so that when they are drawn to one side the
thread and needle will be left in readiness for use.
In order to properly adjust the device, I have attached it to the vertically
reciprocating needle bar G by making a hole through this bar, and a corresponding
hole is made through the rear of the arm of the machine, and this allows a screw 1
to be passed through the hole in the needle bar, and it extends out through the
plate J upon the front of the arm.
To this projecting end of the screw is secured the bent arm K slotted to allow
the screw to pass through, and having a locking nut L by which it is secured at any
desired point.
To the lower arm is hinged a rod or wire M which extends downward and carries
the needle threading block A at its opposite end, so that when the block A is
disengaged from the needle, it may be swung upward around the hinge point of the
rod and held by a clasp O.

page_text: When it is to be used it is turned downward and by springing it a little to one
side, it can be pushed over the needle so that the needle lies in the vertical channel D,
and the spring E clasps and holds it in place as described.
The vertical adjustment of the device is made by means of the screw I and
locking nut L, before described, the slotted arm being slipped up or down until the
hole in the threading device is exactly opposite the eye of the needle. It is then
locked firmly by the nut L and when this is done everything is complete and in
readiness for use at any time.
The device being attached to the needle bar, reciprocates with it and there no
change in its position relative to the needle. By its use the finest needle can be
easily threaded without difficulty.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A threading device for sewing machine needles consisting of a block having a
hole or perforation adapted to coincide with the eye of the needle, an arm to the
end of which the block is secured, and means for adjustably securing said arm and
block to the needle-bar, consisting of a slotted plate fitted to the arm of the
machine and having its lower end connected by a hinged-joint with the upper end
of the arm which carries the block, a screw projecting from the needle bar through
a slot in the arm of the machine, and through the slot in said plate, and a locking nut
for adjustably securing said plate, and provided with means for maintaining the
block elevated when not in use.
2. A needle threading device for sewing machines consisting of a block having a
hole or perforation adapted to coincide with the eye of the needle and direct the
thread there-through, an arm carrying the block at its lower end, a slotted plate
fitted against the arm of the machine having its lower end bent outwardly and
hinged to the upper end of the arm which carries the block, about which hinge the
device may be turned down for use and up out of the way when not in use, a screw
pin from the needle bar passing through a slot in the arm of the machine and through
the slot in the plate, and a nut engaging said pin and adjustably securing the slotted
plate, said nut being provided with a clamp into which the block carrying arm may
be placed and maintained in an elevated position.
3. A device for threading sewing machine needles, consisting of a two part block,
a spring plate by which the two parts are normally held together, a tapered opening
or hole made partially in each block between the meeting faces thereof, a vertical
channel into which the smaller part of the hole opens upon the opposite side, said
channel being adapted to fit the needle, and a spring plate between which and the
block the needle passes, whereby it is retained in the channel with the eye in line
with the hole of the threading block.
