WC, ROBERT WILSON MORRELL, Stuff Merchant, THOMAS PARKINSON,
Skirt Manufacturer, and JOSEPH PARKINSON, Sewing Machine Maker, all
of Bradford, in the County of York, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN SEWING MACHINES," to be as
follows:-
This Invention relates to improvements in the class of machines for
which Letters Patent were granted to Robert Wilson Morrell, dated
23rd March 1865, No. 819, and the present Invention relates to an
improved means. and apparatus for imparting to the forward feed bar
and to the lateral or sideway feed bar the required movements, whereby
the material being sewn or operated upon is fed to, brought under, and
held in proper position for the needles.

I mount on a shaft supported by the end frames of the machine cam
tappets or step wheels, and at each end of the machine levers having
fulcrums about midway their length are provided at their lower ends
with runners or antifriction bowels, which rest or bear on the tappet
wheels; the end of one of the said levers engages with a pin in a slido
block, to which block and to a like slide piece at the other end of
the machine the feed bar for giving the lateral or ordinary feed is
connected. On rotation being imparted to the tappet shaft each suc-
ceeding lift or step on the tappet will move the lever last referred
to on its fulcrum, causing its upper end to act on the pin and slide
piece, so moving the feed step by step while the desired lateral traverse
has been given, whereas other tappets on the tappet shaft will act on
levers lifting or raising the feed bar clear of or above the other cam
step tappets will now act on runners or antifriction bowls attached
to the lower end of pendant levers moving them outward on their fulcra.
About midway the length of the pendant levers are hinged and adjustable
links; these links arc. connected with two slide pieces which support
and carry the forward or front feed bar, which will be moved step by
step forward as each throw or lift of the tappet plates acts on the
pendant levers.
During the period or time the forward feed is in operation the lateral
feed bar will be inoperative by reason of the runners of its levers moving
over a plain part of its tappets, and so will the forward feed bar remain
inoperative from a like cause when the lateral feed bars are inoperative,
'the feed bars being returned to 'their original position by means of
tappets or springs..
The use of the apparatus above described for actuating the feed bars
.dispensing with the movement of the under feed as well as of any
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Wilson Morrell, Thomas Parkinson, and
Joseph Parkinson in the Great Seal Patent Office on the 9th
January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ROBERT
WILSON MORRELL, Stuff Merchant, THOMAS PARKINSON, Skirt Manu- 8

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of July, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty.
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Robert Wilson Morrell, Thomas
Parkinson, and Joseph Parkinson, Her special licence that we, the said
Robert Wilson Morrell, Thomas Parkinson, and Joseph Parkinson, our
executors, administrators, and assigns, or such others as we, the said
Robert Wilson Morrell, Thomas Parkinson, and Joseph Parkinson, our
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
" IMPROVEMENTS IN SEWING MACHINES," upon the condition (amongst
others) that wè, the said Robert Wilson Morrell, Thomas Parkinson,
and Joseph Parkinson, our executors or administrators, by an instru-
ment in writing under our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Robert Wilson Morrell, Thomas
Parkinson, and Joseph Parkinson, do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following
statement and accompanying Sheets of Drawings (that is to say):
This Invention relates to improvements in the class of machines for
which Letters Patent were granted to Robert Wilson Morrell, dated
23rd March 1865, No. 819, and the present Invention relates to an
improved means and apparatus for imparting to the forward feed bar,
and to the lateral or sideway feed bar, the required movements, whereby
the material being sewn or operated upon is fed to, and brought under,
and hold in proper position for the needles.

page_text: f
We mount on a sliaft supported by the end frames of the machine
cam tappets or step wheels (one at each end of the machine); levers
having fulcrums about midway their length are provided at their lower
ends with runners or antifriction bowls which rest or bear on the tappet
wheels; the other end of one of the said levers engages with a pin in ´a
slide block, to which block and to a like slide piece at the other end of
the machine the feed bar for giving the lateral or sideway feed is mounted.
On rotation being imparted to the tappet shaft each succeeding "lift"
or step on the tappet will remove the levers last referred to on its
fulcrum, causing its upper end to act on the pin and slide piece, so
moving the feed step by step until the desired lateral traverse has been
given, whereon other tappets on the tappet shaft will act on levers
lifting or raising the feed bar clear of or above the work. Other cam
tappets will now act on runners or antifriction bowls, attached to the
lower ends of pendant levers, moving them outward on their fulcrums.
About midway the length of the pendant bars are hinged and adjustable
links; these links are connected with two slide pieces which support
and carry the forward or front feed bar, which will be moved step by
step forward as each throw or lift of the tappet plate acts on the pendant
levers.
:
During the period or time the forward feed is in operation the lateral
feed bar will be inoperative by reason of the runners of its levers moving
over a plain part of their tappets, and so will the forward feed bar remain
inoperative from a like cause when the lateral feed bar is in operation,
the feed bars being returned to their original position by means of
tappets or springs..
In order that this Invention may be fully understood, we herein give
reference to accompanying Sheets of Drawings of a machine with our
improvements applied thereto.
Fig. 1 is an end elevation; Fig. 2, a side elevation; and Fig. 3 is a
detail shewing a modification of some part of our improvements.
A is the feed bar for giving the forward motion to the material under
operation, and B is the lateral or sideway feed bar; C is a shaft, which
is mounted in the end frames D of the machine; E is a cam or step
wheel which acts on the friction pulley F" of the lever F, which lever is
,hinged at G, and the top end of the said lever bears against a pin H in
the slide H', to which slide the feed bar B is attached by means of the

page_text: pin J passing through the piece J' on the end of the feed bar. The
Drawing shews the bar just at the point of commencing the lateral feed:
By the time the cam E has performed half a revolution the lateral feed will
be completed, whereon the cam K acting on the levers K and K (the latter
of which is attached to the feed bar at "a") will raise the said bar clear
of or above the work, and the forward feed bar A is next put into operation.
This feed bar is mounted (similarly to the feed bar B) in slides L, which
slide pieces are connected by links M to the pendant levers N, at the
bottom of which are antifriction bowls Q bearing against cams R. As
these cams rotate the feed bar is moved step by step, and by the timo
that they have performed half a revolution the feed bar B will have
completed its travel in the required direction; it is 'then raised above
the work by cams S acting on levers S1 and S2, the latter being connected
to the feed bar at "b." The return motion of both feed bars is effected by
springs; those for the forward feed bar A are shewn at "c," the spring
for actuating the feed bar B being attached to the lever F at the other
end of the machine.
Although we have described the feed bars as being lifted from the
material, and drawn back to their original positions by means of springs
when the travel in one direction has been completed, it will be obvious'
that the feed bars may be used for moving the material in both directions,
that is, backward and forward, and from right to left, and vice versa, by
means of suitably arranged cams, according to the combination pattern
required.
It has not been thought necessary to illustrate both ends of the
machine, on account of the similarity of the mechanism.
Instead of the arrangement of levers shewn in Fig. 1 for effecting the
forward feed that shewn at Fig. 3 may be adopted.
In the accompanying Drawings the slides and slide boxes L and H¹
O are shewn at right angles, whereby the stitches produced by the two
feeds are likewise at right angles. It will however be readily seen that
by altering the angle of the slides the figures produced by the stitches
may be varied; also by making the grooves in the slides curved a similar
pattern will be produced on the material under operation.
5
By referring to Fig. 4 it will be seen that the material is inserted in
the machine at an angle of 45°; by first moving the material laterally

page_text: and then forward the diamond pattern is produced. It will be seen
that if the material were not inserted at this angle the lateral feed
would in time draw the material to one side of the machine, and further
progress would be impossible.
Having thus described the nature of our said Invention, and shewn
by Drawings how the same is to be or may be performed or carried into
practice, we would have it understood that we do not confine ourselves
to the precise details herein set forth, as the same may be modified;
but what we claim as our Invention and believe to be new is,―
Firstly. The use or employment of two feed bars, each having a :
separate action or movement regulated by cams and tappets, substan-
tially as herein shewn and described.
+
Secondly. The means herein shewn and described, whereby the
material under operation is moved by the feed bar any required number
of stitches without a separate lift for each stitch as heretofore, and con- -
sequently avoiding the disengagement of the cloth, and securing greater
exactness of pattern in the sewing.
. Thirdly. The application of slides for guiding the feed bars, whereby
a variety of patterns may be produced, substantially as shewn and
described.
In witness whereof, we, the said Robert Wilson Morrell, Thomas
Parkinson, and Joseph Parkinson, have hereunto set our hands
and seals, this Sixth day of January, in the year of our Lord
