PROVISIONAL SPECIFICATION left by the said Benjamin Hague at the
Office of the Commissioners of Patents on the 21st September 1882.
BENJAMIN HAGUE, of the town and county of the town of Nottingham,
"IMPROVEMENTS IN STITCHING MACHINES,"
I employ two modifications of machines, the first modification consists of the
following parts, a metal platform or bed plate, from which bearings project, and to
which other bearings are secured for the several parts, namely, a double plug bearing
carrying the axle plate on which a ring plate revolves, this plate has saw gates cut
on its upper edge, in which steel points are soldered, upon these points the fabric
to be stitched is placed by the attendant, within the ring of points is a toothed
ring, which is protected by a cover plate above it, this ring is caused to revolve by
a toothed pinion secured on one end of an axle shaft at right angles to the point
ring, the reverse end of the shaft carries a ratchet wheel, held by a stop lever and
spring and driven by a clawker, hinged to a projection on a rocking lever carrying a
needle at its lower end above which is a stud, which takes into a groove in the
operating cam, the reverse side of the cam operates a tumbler lever carrying a hook
which secures the thread, the fabric is stitched with and retains such thread in the
form of a loop until the fabric is traversed the length of a stitch, and the needle
has entered such loop, when it is released, and the further advance of the needle
draws the previous loop tight. The cam shaft also carries a grooved pulley for a
band from any prime mover, this pulley slides on the cam shaft, and is provided
with a stud or driving pin, which takes into a recess in one side of an excentric
cam fast on the cam shaft, this cam operates a double ended rocking lever, which
gives reciprocating movements to a cutter blade carried by a bracket secured to the
axle plate first named, the cutting edge of the blade slides over the cutting edge of
a second blade, also secured to the axle plate, by such means I am enabled to cut
Prine 621

page_text: off the superfluous fabric, close above the steel points as fast as the fabric is
stitched.
The second modification of machine consists of a ring plate, carrying steel points
revolved by a worm and toothed wheel, the axle of which carries a smaller toothed
wheel gearing into the teeth of the ring plate, the lower end of the axle shaft
carrying the driving worm is provided with a hook revolving with it, this hook
secures the thread supplied by a needle carried by a sliding bolt, operated by a
rocking lever carrying a stud at its upper end, actuating a second rocking lever,
the lower end of this lever operates a sliding bolt attached to a cutting blade as
described in the first modification sliding upon a second fixed blade, the first
named rocking lever is connected by a ball and socket joint to a connecting rod
operated by an excentric on the upper end of the driving shaft, provided with a
grooved pulley for a belt, this grooved pulley being horizontal, the machine is
provided with other vertical pulleys to guide the driving belt, the whole of the
bearings for the above parts, form part of the bed plate or bearings are secured to
the bed plate where required, this machine operates the same way as the first
described.

"IMPROVEMENTS IN STITCHING MACHINES
"
I employ two modifications of machines, the first modification consists of the
following parts, a metal platform or bed plate, from which bearings project, and to
which other bearings are secured for the several parts namely a double plug bearing
carrying the axle plate on which a ring plate revolves, this plate has saw gates cut
on its upper edge in which steel points are soldered, upon these points the fabric to
be stitched is placed by the attendant, within the ring of points is a toothed ring
which is protected by a cover plate above it, this ring is caused to revolve by a
toothed pinion secured on one end of an axle shaft at right angles to the point ring;
the reverse end of the shaft carries a ratchet wheel held by a stop lever and spring;
and driven by a clawker hinged to a projection on a rocking lever, carrying a
needle at. its lower end, above which is a stud, which takes into a groove in the
operating cam, the reverse side of the cam, operates a tumbler lever carrying a
hook which secures the thread, the fabric is stitched with and retains such thread
in the form of a loop until the fabric is traversed the length of a stitch, and the
needle has entered such loop, when it is released, and the further advance of the
needle draws the previous loop tight. The cam shaft also carries a grooved pulley,
for a band from any prime mover, this pulley slides on the cam shaft, and is
provided with a stud or driving pin, which takes into a recess in one side of an
eccentric cam fast on the cam shaft, this cam operates a double ended rocking lever,
which gives reciprocating movements to a cutter blade carried by a bracket
secured to the axle plate first named the cutting edge of the blade slides over the
cutting edge of a second blade, also secured to the axle plate, by such means I am
enabled to cut off the superfluous fabric, close above the steel points as fast as the
fabric is stitched. The second modification of machine consists of a ring plate
carrying steel points revolved by a worm and toothed wheel, the axle of which
carries a smaller toothed wheel gearing into the teeth of the ring plate, the lower
end of the axle shaft carrying the driving worm is provided with a hook revolving
with it, this hook secures the thread supplied by a needle carried by a sliding-bolt
operated by a rocking lever carrying a stud at its upper end actuating a second
rocking lever, the lower end of this lever operates a sliding bolt attached to a
cutting blade as described in the first modification sliding upon a second fixed
blade, the first named rocking lever is connected by a ball and socket joint, to a
connecting rod operated by an eccentric, on the upper end of the driving shaft,
provided with a grooved pulley for a belt, this grooved pulley being horizontal, the
machine is provided with other vertical pulleys to guide the driving belt, the whole
of the bearings for the above parts form part of the bed plate, or bearings are
secured to the bed plate where required this machine operates in the same way as
the first described
.:

page_text: My improved stitching machine consists of the following parts, a metal bed
plate from which bearings project in which a cam shaft A revolves, on this shaft is
secured a double cam A the left side of which forms an excentric groove, in
which a friction piece slides and receives a stud which operates a rocking
lever A carrying a needle seen in Figure 2 at its lower end, the reverse side
of the cam operates a tumbler lever A³, in which a hook A' is capable of
adjustment, this hoop. secures a loop of the thread, which the needle passes.
through the fabric to be stitched, the thread, being supplied from a spool above
the machine (and shewn only in the side view Figure 2) the hook retains
the thread in the form of a loop until the fabric is traversed the length of a
stitch, and the needle has entered such loop when it is released, and the further
advance of the needle draws the previous loop tight. The rocking lever A2 has
a projection on its front in which an axle is capable of adjustment, this axle
carries a clawker B hereafter referred to. The cam shaft also carries a grooved
pulley for a band from any prime mover, this pulley slides on the cam shaft and is
provided with a stud or driving pin, which takes into a recess in one side of an
eccentric cam C, the driving pin being thrown into or out of gear by means of a
small lever rocking on an axle, secured in the bed plate, and shewn in Figure 1.
The above described parts are those which are usually employed in stitching
machines having a revolving point ring to receive the fabric to be stitched. The.
improved portions of the machine consist of the following parts. A double plug
bearing D (shewn separately in a side view at Figure 3) the upper portion of which
is securely held in the boss of a bracket D¹ attached to the top of the bed plate, to
the lower portion is secured an axle plate D³, shewn in plan at Figures 1 and 6, on
which a ring plate D³ revolves this plate has saw gates cut in its upper outer edge
in which steel points are soldered, upon these points the fabric to be stitched is
placed by the attendant, the needle entering the fabric just above the points;
within the ring of points the inner upper edge of the ring is toothed, portion of
these teeth are shewn in plan at Figure 1, and portion in side view at Figure 6, the
teeth are protected by a cover plate D above them, the ends of the plate being
secured by screws to the top of the axle plate D2 one side of the cover plate is
raised so as to just pass clear over a toothed pinion wheel E which gears into the
teeth of the ring plate, the pinion wheel is secured on one end of an axle shaft,
which revolves in the double plug bearing D the reverse end of the shaft carries a
ratchet wheel E, which is moved one tooth at each revolution of the cam shaft by
the clawker B, and is held where placed by a stop lever E2, and a spring attached
to it, and a stud in the bearing D. The eccentric cam C, operates a double ended
rocking lever C¹ (both of which are shewn in side view at Figure 5) which is
forked at its lower end and clips the projecting arm of an upper cutting blade C³,
which rocks upon an axle pin, secured in a lower cutting blade C³, these blades are
shewn in plan at Figure 9, the lower cutting blade is secured to the underside of
a bracket E³, carried by a bevel edged plate E¹ attached to the axle plate D², before
named, above the cutting blade C2 rocking upon the same axle pin is a bracket C
held securely upon the axle by a nut and lock nut, one end of this bracket is
provided with an adjustable set screw and lock nut, the lower end of the screw.
takes into a hole near the pointed end of the cutting blade C, thus regulating the
pressure of the upper blade or the lower one; the rocking lever C₁ not only gives
a reciprocating movement to the blade C over the blade C³, but the point where
the two blades meet to cut off the fabric, as fast as it is stitched can be adjusted by
raising or lowering the vertical bolt C, in the upper arm of the lever C¹, and
securing it by the set screw shewn at Figures 1 and 5, the bolt C³ carries a friction
piece at its lower end, so that when the cutting parts of each blade, become dull,
the sharp portions nearer the points of the blades may be successively adjusted to
cut the fabric, until the whole length of the blades become dull, when they will
require to be taken off and resharpened their whole length. The bracket C4 is
shewn separately in plan at Figure 8 and in side view with the two cutter blades
at Figure 10. The bracket E is provided with a vertical rod capable of adjustment

page_text: in it by means of a set screw; to the lower end of the rod is attached a plate E*,
this plate lies just above the points carried by the revolving ring plate D³. The
plate E' prevents the stitched fabric from curling over on to itself, before it reaches
the cutting blades, and the bevelled plate E' prevents the fabric from curling over
before it is stitched. On the top of the plate E is secured an arm E³, the outer end
of which is lined on the underside with leather, and lies over the boss of the ratchet
wheel E, the edge of the arm pressing upon the wheel keeps it in position. In
addition to the plates E1 and E2, to prevent the fabric above the points from curling
over upon itself I employ a screw F which revolves in the front end of a lever Fi
which is capable of adjustment, on the outer side of the left bearing of the cam shaft
below the shaft, which projects through the bearing and carries a pulley F' round
which a belt is passed, the belt being also passed round a larger pulley F³, which
carries a smaller pulley F round which a belt is passed and also round a pulley F"
on the outer end of the screw F. By such means the screw is rotated in the
direction indicated by the arrow on the pulley F, thus preventing the two edges
of the fabric from curling over upon itself, before the edges are stitched together.
By means of a stitching machine constructed and operating as above described I
am enabled to stitch two or more thicknesses of fabric together above the points of
the revolving ring, and cut off the superfluous fabric as fast as it is stitched.
Having thus described the nature of my said invention and the manner of
performing the same, I declare that I claim :-
First For stitching the fabric above the pins or points.
Second For cutting off the superfluous fabric above the pins or points.
Third, For the construction and employment of the two plates E' and E³, above
the pins or points for uncurling the fabric, and holding it up while it is stitched
and the superfluous portion cut off.
Fourth. For the construction and employment of the ring plate D³ carrying pins
or points to enable the fabric to be stitched above the pins or points, and affords
the attendant greater facility to manipulate the fabric under the ring plate
Fifth For the construction and employment of a pair of cutting blades, and
two uncurling plates, applied to a stitching machine, in which the fabric is stitched,
and cut off above the pins or points, the whole substantially as described and
illustrated in the drawings annexed
In witness whereof I the said Benjamin Hague have hereunto set my hand
and seal this seventeenth day of March in the year of our Lord one
thousand eight hundred and eighty three
