PROVISIONAL SPECIFICATION.
Improvements in Hackling Machines.
ABRAM COMBE of Falls Foundry Belfast Ireland Machinist do hereby declare
the nature of this invention to be as follows :-
•)*
These improvements in hackling machines consist of new arrangements for raising
and lowering the channel which carries the holders and also for sliding the holders
from over one tool to over another.
The novelty of the arrangement for raising and lowering the channel which carries
the holders consists in the peculiar form of the lifting lever which is controlled by a
runner on the main motion wheel.
The lifting lever is made in the form of a loop at one end of which is the stud on
which it swings.
To the upper side of the loop a connecting rod is attached which communicates
motion to the lifting shaft at the top of the machine the connecting rod being attached
to the looped lever by means of a clip which can be readily set to the required position
on the lever to give the desired length of lift.
The lower part of the looped lever is acted upon by a runner attached to the main
motion wheel and the surface of the looped lever upon which the runner acts is so
formed that the desired differing rates of speed are given to the channel in its rise
and fall and a rest or dwell is obtained for the operation of sliding the holders from
over one tool to over another.
The novelty of the arrangement for sliding the holders from over one tool to over
another consists in using a tappet placed on the opposite side of the main motion
wheel to the runner which actuates the looped lifting lever and making this tappot
actuate a runner carried by a lever which is connected by a rod to the ordinary
weighted lever that slides the holders from over one tool to over another.
The tappet raises the ordinary weighted lever while the holders are stationary in
the channel and liberates it when the channel is at rest at its highest position to
enable it to slide the holders from over one tool to over another and the tappet is
formed in such a way that the action of lifting the weight and sliding the holders
takes place smoothly and without jerks or vibrations.

COMPLETE SPECIFICATION.
Improvements in Hackling Machines.
ABRAM COMBE of Falls Foundry Belfast Ireland Machinist 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 :-
These improvements in hackling machines consist of new arrangements, and
appliances, employed for raising, and lowering the channel which carries the holders,
and also for sliding the holders from over one tool to over another.
The improvements above referred to are illustrated in the drawings herewith in
which Fig. 1. is a side view of so much of a hackling machine as is necessary to
illustrate the application thereto of my invention.
Fig. 2. is an end view of the same, and Figs. 3, 4 and 5 are details or parts
detached, and drawn upon a larger scale. The same letters, and figures of reference
being employed to indicate the same or like parts in the several figures.
The novelty of the invention for raising and lowering the channel (c) which carries
the holders (h) consists in the peculiar form of the lifting lever, (a) and an adjustable

page_text: clip, hereinafter described, which lever (a) is controlled by a runner (4) on the main
wheel (b).
The lifting lever (a) is made in the form of a. loop-atrone end of which is the
fulcrum stud (a) upon which it swings.
To the upper side of the loop a connecting rod (d) is attached, which communicates
a rocking motion to the lifting shaft (e) at the top of the machine, the connecting
rod (d) being attached to the looped lever (a) by means of a clip (d'). which by
slackening and tightening a nut (d2) can be readily set, or adjusted to the required
position on the lever (a), to give the desired length of lift to the channel (c) which
carries the holders (h).
The lower part of the looped lever (a) is acted upon by a runner (1) attached to
the main wheel (b), and the surface of the looped lever (a), upon which the runner (61)
acts, is so formed that the desired differing rates of speed are given to the channel (c),
in its rise, and fall; and a rest or "dwell" is obtained for the operation of sliding the
holders () from over one tool to over another.
The novelty of the invention for sliding the holders (h) from over one tool to 'over
another consists in using a tappet (f) placed on the opposite side of the main
wheel (6) to the runner (6), which actuates the looped lifting lever (a), and making
the tappet (f) actuate a runner (g) carried by a lever (g), which is connected by a
rod (s) to the ordinary weighted lever (k), that slides the holders (h) from over one
tool to over another.
The tappet (f) raises the ordinary weighted lever (k), while the holders (h) are
stationary in the channel (c) and liberates it when the channel (c) is at rest at its
highest position in order to enable the weighted lever (k) to slide the holders (h)
from over one tool to over another, and the tappet (f) is formed in such a way that
the action of lifting the weight on the sliding lever (k) and sliding the holders (h)
takes place smoothly, and without jerks or vibrations.
I have described, and shewn a form of lever (a) which gives satisfactory results;
but I do not confine myself to the form or configuration thereof as illustrated as it is
obvious that the shape may be varied without departing from the principle of the
invention so long as it is provided that the "race," for the runner (1) therein, gives
the requisite varied motion to the rod (d); and connections.
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:
I. The looped lever (a), and adjustable clip attachment d' and a runner such as b
all in combination, for giving the lifting motion in hackling machines, and as herein
described, and substantially as illustrated by drawings annexed.
II. The sliding tappet (f), (on the opposite side of the wheel (b) to runner (¹))
runner (9), and lever (g) all in combination, and as, and for purpose herein set
forth, and substantially as illustrated by annexed drawings.
