")
This invention relates Firstly to the use in combination of certain appliances
hereinafter described whereby all motion or movement of the slay or "going part"
is abolished and a fixed and stationary reed and shuttle race are available―
secondly, To improved apparatus for operating the healds.
The slay and reed are carried or supported on fixed upright arms so that the
whole is stationary, the shuttle or shuttles is or are brought into line with the
race for picking by means of horizontal boxes operated by stud wheel and forked
levers as ordinary or otherwise moved and set in line with the race. A comb or
rake is mounted upon arms connected to levers carried by a cross shaft (counter-
balanced by weight) and operated by means of cam plate so as to cause the said
comb or rake to be raised and passed through the warp and then by a forward
movement to beat up the weft in lieu of the beat up being performed by the reed
as in a going slay and read beating up.
For operating the healds we utilize the motion or turn of the peg barrel so as to
slide endwise a bar, on which at intervals of its length are placed inclines or cam
surfaces the latter push forward L levers the lower part or arm of which move
the ordinary hooks into position for engaging with the hook of the heald rods
which lift the healds as required.

This invention relates-Firstly-To the use in combination of certain appliances
hereinafter described whereby during the ordinary working of the loom all motion
or movement of the slay or "going part is abolished and a fixed and stationary
reed and shuttle race are available-Secondly-To improved apparatus for operating
the healds.
The slay and reed are carried or supported on upright arms, so that the whole is
stationary, the shuttle or shuttles is or are brought into line with the race for
picking by means of horizontal boxes operated by forked levers and wheels or
otherwise moved and set in line with the race. A comb or rake is mounted upon
arms connected to levers carried by a cross shaft and operated by means of cam
plate so as to cause the said comb or rake to be raised and passed through the
warp, and then by a forward movement to beat up the weft, in lieu of the beat up
being performed by the reed, as in a going slay and reed beating up.
For operating the healds we utilize the motion or turn of the peg barrel so as
to slide end wise a bar, on which at intervals of its length are placed inclines or
cam surfaces, the latter push forward L levers, the lower part or arm of which
move the ordinary hooks into position for engaging with the hook of the heald
rods which lift the healds as required.
Such being the nature and particulars of this our said invention we will now
proceed to describe the same in detail and in order that the invention may be fully
understood We have hereunto annexed sheets of drawings and have marked the
same with figures of reference.

page_text: operated by tappet and upright 15 working through guide brackets 16 the
rack wheel will be turned in the direction shewn by the arrow moving the boxes
to the right but when the lever 12 is raised by the jacquard (11 will be down)
and the rack 8 will be in gear with rack wheel 10 and the shuttle boxes move in
the opposite direction or to the left hand-When the box is to be moved more
than one cell or shuttle (skipping) a tappet of greater throw 17 will be brought
into position to act on end 18 of the L lever 13 the tappet 17 being made hollow
so as to slide over or enclose the tappet 14 and the sliding motion of the tappet is
by fork lever 19 under control of the jacquard as is well understood-At 20 is the
comb or rake mounted upon arms 21 the teeth 22 being mounted on the rod 23
having spacing pieces 24 providing requisite distances between the teeth for
reception of the warp threads-25 are nuts of the rod 23-When the comb 20 has
been placed in position the slide piece or holding bar 26 is securely fixed to the
slide 27 and holds the comb 20 firmly in position. the arms 21 are connected to the
levers 28 carried by the fulcrum shaft 29. the comb 20 is raised and lowered by
means of the cam and lever 30-The forward movement of the comb 20 to beat
up the weft is obtained by the levers 31-and the crank 32 producing the ordinary
double beat up.
At 33 is the peg barrel or jacquard cylinder in which are the
holes 34 to allow the end 35 of the bar 36 to enter when the bar is required to be
stationary, and its L lever 37 to engage the catch 38 of the heald rods 39-When
the peg barrel 33 brings a blank side 40 against the end 35 of the bar 36 the
cam surface 41 will force the L lever 42 ready for engaging with its corresponding
heald hook.
Having thus fully described the nature and particulars of this our said
invention together with the manner in which the same is to be performed and
carried into practical effect we would have it understood that we claim as our
invention
The stationary slay and reed combined with the comb or rake for beating up
the weft constructed and operated as described and illustrated by the annexed
drawings.
The improved apparatus comprising the bar 36 cam 40-L levers. 37-and 42
operated by the jacquard cylinder 33 constructed and combined as herein described
and shewn by the drawings.
In Witness whereof
the said William Irving for and on behalf of myself
and the said Frederick Howarth have hereunto set my hand and seal this fifth
day of December in the year of our Lord one thousand eight hundred and
eighty three.
