PROVISIONAL SPECIFICATION.
An Improved Construction of the Taking-up Catch Mechanism
Employed in Looms for Weaving.
We, HENRY AINSWORTH, of Harwood Mount, Great Harwood, in the County of
Lancaster, Weaving Manager, WILLIAM CAMPY, of 41 Clayton Street, in the same
place, Weaving Manager, and JOSEPH ANDERTON of 55 St. Hubert's Road, in the
same place, Engineer, do hereby declare the nature of this invention to be as
follows:--
This invention of an improved construction of the taking-up catch mechanism
employed in looms for weaving consists in making the catch or pawl in a double form
and in so mounting it that it may be readily detached from its bearing on the upper end
of the ordinary rocking lever and be at once replaced in a transposed position. To
this end we form the upper end of the rocking lever with a circular aperture or
bearing. A vertical slot somewhat narrower than the diameter of the circular
aperture forms a passage from the bearing and through this slot or passage one of two
round pins or pivots (flattened on two opposite sides) with which the double pawl is
provided is passed through to the bearing. The flattening of the pin or pivot sides is
so arranged as to permit of the double pawl being easily slipped in or out of its
bearing in a nearly vertical direction; the rounded part of the pivots fitting easily
within the circular aperture; the relations of the flattened sides of the pivot and the
slot being such that when turned upwards the larger diameter of the pivot is presented
to the mouth of the slot and the pawl cannot therefore be withdrawn from its bearing
when in working position.
The double pawl has its two extremities sloped down or pointed to suit the form of

page_text: the catch wheel teeth, its central part consisting of two flat sides (forming a hollow
intervening space which fits easily upon the flat side surfaces of the upper end of the
rocking lever), the two pins or pivots (one for each pawl) passing across the hollow
space and being placed respectively near each end thereof.
The parts as above described may all be produced (ready for putting together) in
cast metal and thus the necessity of hole drilling and rivetting loose pins is dispensed
with; increased durability and facilities for rapidly reversing or replacing the pawls
being moreover afforded.

We, HENRY AINSWORTH of Harwood Mount, Great Harwood in the County of
Lancaster, Weaving Manager, WILLIAM CAMPY of 41 Clayton Street, in the same
place, Weaving Manager, and JOSEPH ANDERTON, of 55 St. Hubert's Road, in the
same place, Engineer do hereby declare the nature of this invention, and in what
manner the same is to be perforined, to be particularly described and ascertained in
and by the following statement :-
This invention of an improved construction of the taking-up catch mechanism
employed in looms for weaving consists in making the catch or pawl in a double form
and in so mounting it that it may readily be detached from its bearing on the upper
end of the ordinary rocking lever and be at once replaced in a transposed position.
The accompanying Drawings illustrate the nature and details of our said invention.
Fig. 1 is a side view of our improved taking-up catch mechanism;
Fig. 2 is a similar view with the double catch or pawl shewn in section ;
Fig. 3 is another similar view shewing the mode of removing or replacing the
double pawl; and
Fig. 4 is a plan view of the double pawl detached.
We form the upper end of the rocking lever A with a circular aperture or bearing b.
A vertical slot c, somewhat narrower than the diameter of the circular aperture b,
forms a passage from the bearing, and through this slot or passage one of two round
pins or pivots d d (flattened on two opposite sides) with which the double paw! E is
provided is passed through to the bearing b. The flattening of the pins or pivots is
so arranged as to permit of the double pawl E being easily slipped in or out of its
bearing in a nearly vertical direction (as shewn at Fig. 3) the rounded part of the
pivots fitting easily within the circular aperture b; the relations of the flattened
sides of the pivot d and the slot c being such that when the pawl is turned upwards
(as shewn in Figs. 1 and 2) the larger diameter of the pivot is presented to the mouth
of the slot c and the pivot cannot therefore be withdrawn from its bearing when in
working position.
The double pawl has its two extremities sloped down or pointed to suit the form of
the catch wheel teeth W, its central part consisting of two flat sides (forming a
hollow intervening space which fits easily upon the flat side surfaces of the upper end
of the rocking lever A), the two pins or pivots d d (one for each pawl) passing across
the hollow space and being placed respectively near each end thereof.
The parts as above described may all be produced (ready for putting together) in
cast metal and thus the necessity of hole drilling and rivetting loose pins is dispensed

page_text: with increased durability and facilities for rapidly reversing or replacing the pawls
being moreover afforded.
Having now particularly described and ascertained the nature of the said
invention, and in what manner it is to be performed we declare that what we
claim is
The use or employment in looms for weaving of taking-up catch mechanism
constructed and arranged substantially as described and shewn in the Drawings.
