I, ANDREW GUTHRIE, of Halliburton Place, Galashiels, in the County of Roxburgh,
North Britain, Engineer do hereby declare the nature of this invention to be as
follows:-
This Invention relates more particularly to an improvement upon the Harness
Engine of the Hill and Hattersley Open Shed Power Loom for the purpose of
obviating the difficulty experienced in mending broken warp threads by reason of
the heddles remaining always up when the loom is stopped.
The Invention consists in applying lifting bars at the points of the levers which
project at the end of the Harness Engine and to which the heddles are connected.
The weaver has control over these bars by a handle in front of the loom so that when
the weaver requires to have the heddles level in order to mend the broken warp
threads the said handle is pulled and the bars lift the ends of all the levers which
are out and this allows the heddles to become level, and a further advantage is
obtained in that the tuner can go over the leaves and see that all is in order with
greater facility and in less time than heretofore.

page_text: Improvements in or relating to the Harness Engines of Open
Shed Power Looms.
1, ANDREW GUTHRIE of Halliburton Place, Galashiels, in the County of Rox-
burgh, North Britain, Engineer, 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:—
This invention relates more particularly to an improvement upon the harness engine
of the Hattersley and Hill open shed power loom for the purpose of obviating the
difficulty experienced in mending broken warp threads by reason of a quantity
of the heddles remaining always up when the loom is stopped.
This is attained by the means illustrated in the drawings hereunto appended, in
which fig. 1 is a sectional front elevation of a harness engine and loom, only a suffi-
cient portion of each being shewn to illustrate this invention; and fig. 2 is an end
elevation of said harness engine.

The invention consists in applying lifting bars a a¹ at the points of those levers or
draw catches 6 b¹ which project at the end of the harness engine and to which the
heddles c are connected by the strings d d', levers e e¹ff, connecting rods 9 g¹ g³ g³
and levers h and i in the well known manner. The cause of said draw catches b
being made to project as above set forth is by reason of the draw-bars or knivers k k¹
operating them in order to effect the raising or lifting of the heddles c as is well
understood, so that only those draw catches that are in connection with the heddles
thus lifted, project as above described, the remainder of said draw catches 6' being
in connection with those heddles which are not raised.
The bars a a¹ are joined together at their outer ends by the upright pieces 11,
through which their said outer ends pass in order to operate in slots made in the
guides mm². The said upright pieces are joined by the rods n n¹ to the
Levers o o¹ (the lever o¹ being a bell cranked lever) which are rigidly mounted on the
shaft P₁ and to said lever o¹ is joined or coupled the levers by the rod t. To said
levers is attached the handle u.

Whenever it is desired to level the heddles or in other words to place all the threads
of warp into the same plane, in order to repair the broken ones and for other objects
and purposes well known to every one conversant with this class of loom;
it is only
necessary for the weaver to pull at the handle u by which, through the levers 8, 0, 0,
rods t and n, n¹ and upright pieces ; the bars a a¹ are lifted, forcing the draw
catches bor b¹ out of connection (as shewn in broken lines fig. 1b) with their draw
bar or kniver or k¹ as the case may be, according to which series of said draw
catches 6 or b¹, projects (the drawcatches b are illustrated as projecting), in this
manner allowing all the heddles c that may be raised thereby, to fall by gravity or be
pressed down by the weaver, or the operative, level with or into the same plane as
those heddles that were not lifted.

page_text: 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. The bars a and a placed in the position beneath the series of draw-catches b
and 6' as herein set forth and illustrated, in combination with said draw-catches b
and 61; said bars a and a¹ being arranged to operate said series of draw-
catches 6 and 6' substantially as specified.
2. The combination of the bars a a¹, the joining pieces I l, means for operating
same, and the guide pieces m m¹, with the draw-catches 6 6¹ forming part of the
harness engine herein before referred to, the whole being arranged to operate sub-
stantially as and for the purpose specified.
