"AN
IMPROVED MACHINE FOR SEWING AND STITCHING GLOVES AND OTHER SIMILAR
ARTICLES."
The sewing machine which is the subject of the present Invention is more
especially intended for stitching gloves, but it is also applicable to sewing or
stitching other articles. It is distinguished from the machines bitherto employed
for the same purpose by the four following arrangements.
1st. The shuttle, instead of being placed as in existing machines below the
vertical needle in combination with which it works to make the knot, is placed
above the said needle, that is to say, that the respective positions of the two
essential parts are reversed.
2nd. The shuttle employed by preference in this machine permits of using a
bobbin containing a much larger quantity of thread than in the ordinary systems.
This result is due to the particular arrangement of the mechanism which imparts
to the shuttle its rotary movement. This mechanism comprises as essential parts
two tenons engaging in mortises formed on the shuttle, which is placed a little
obliquely so that the tenons can leave their mortises to allow of the loop to pass,
and thus act like the pallets of an anchor escapement.
3rd. The feed foot or presser is actuated by the carrier which holds the shuttle
and can be raised during the work by means of a pedal adjoining the driving pedal.
4th. The bed of the machine is in the form of a cylinder movable around its
axis, so as to draw all the machine in the direction desired for the convenience of
the work.
Such being the novel features of my Invention, I proceed to describe a machine -
constructed in accordance therewith for sewing and stitching gloves.
The bed of the machine is a hollow cylinder, and contains part of the driving
mechanism. The ends are cast with hollow trunnions serving as axes to the
cylinder, and turning in bearings bolted to the platform of the table; a pressure
screw prevents oscillating movement of the cylinder if necessary. The driving
shaft passes through the hollow trunnions; it carries the driving pulley at one
end, and at its other end is the mechanism which imparts the up-and-down move-
ment to the vertical needle. This mechanism is composed of a crank fixed to the
Iriving shaft and connected by a rod to the needle rod by means of a screw

the cylinder freely through two holes diametrically opposite cach other, and it
terminates at its upper end in a split screw, in which the needle is placed, and
secured by a small nut. The needle rod is surrounded by a vertical sleeve fixed
by screws to the upper surface of the cylindrical bed. Near the connecting rod
the driving shaft is supported by a small bracket or chair on the lower surface of
the cylinder.
I now come to the part of the machine which relates to the shuttle. This shuttle
is particularly characterized by its mechanism. All the parts of this mechanism
are carried by an arm similar to that of ordinary sewing machines. The rotary
motion of the shuttle is transmitted to it from the driving shaft by means of
bevilled gearing, a vertical shaft, and an upper horizontal shaft; this last-named
shaft carries at its end a plate furnished with two tenons engaging in mortises in
the shuttle. These are the tenons which give the shuttle its rotary motion, but
as it is placed in a position slightly inclined to the vertical plane of the ends of
the tenons, they alternately quit and enter their mortises and render the shuttle
free to pass into the loop formed by the needle, an escapement action which is an
essential feature of my Invention. The shuttle. thus actuated turns with slight
friction in its carrier, which guides it in a slightly oblique position, it is provided
with its hook which seizes the loop of thread from the needle and it is hollowed
out to receive the bobbin. The bobbin is mounted loosely on a small socket in

supported at the end of the horizontal arm of the machine immediately above the
needle. It is to this carrier that the feed or presser apparatus is fitted. This
apparatus produces the feed of the work by a to-and-fro movement, produced
by a cam which is keyed on the upper horizontal shaft near the plate before
mentioned. This cam acts on a projection of the feed foot which rises and descends
at the same time that it is displaced laterally by the abutting of an adjustable
screw against the edge of the shuttle carrier. The head of the feed foot is formed
with a hole which serves to guide it in its movement; it is provided with a pro-
jection to which a spring is attached to give the desired pressure. By means of
a small cam with a handle, the feed foot can be raised above the fabric. But an
arm actuated by a cord from a pedal allows the operator to lift the feed foot if
necessary while the work is proceeding.
The machine constructed as herein-before described is employed in two ways
for glove work, that is to say, that it will produce the stitching on the back of
the glove and also the sewing for the fingers; in the first case the skin is placed
flat on a small work plate; in the second case this work plate is removed and the
finger to be sewn is placed on the sleeve (before-mentioned) of the needle rod,
bringing the two edges of the skin under the hole through which the needle passes.
