.Improvements relating to "Kenyon's Under-motion" for Operating
the Healds of Looms.
I, WILLIAM HENRY KENYON, of Denby Dale, near Huddersfield, Yorkshire,
Machine Maker, do hereby declare the nature of this invention to be
follows:-
as
This invention has reference to what is now commonly called "Kenyon's
under-motion," and for which Letters Patent were granted to me on the 14th
day of June 1883, No. 2960, and again on the 25th day of January 1889, No. 1370.
The invention described therein comprised certain levers, which by spiral springs
and cords were connected to the heald shafts for bringing the healds down after
having been lifted in the ordinary manner. The levers, named above, are not
attached direct to the spiral springs, but to a length of leather between the
lever and the spring. To the use of this leather connection, there are many
objections, therefore one object of my present invention is to dispense with the
said leather connection, and employ instead thereof metal links, coupled together
after the manner of hooks and eyes. These links are made of different lengths
or sizes so that when put together I can form a chain of any suitable length so
as to put more or less pressure on the healds, such said links being inter-
changeable after having once been fitted. The lever is made in two parts, and
after it is placed onto its. stud through a slot, a loose piece or loop is passed
over the end of the lever, the arrangement being such that the lower end of
of the loop bears against the fulcrum stud, and thus prevents the possibility of
the levers getting out of place. The top end of said loop stands above the
circle of the lever, and is so placed as to come into contact with a stud, and
thus limit the range of the lever, and prevent it from coming in contact with
any other part of the machine. The levers being thus formed in two parts can
be easily taken to pieces and taken out and replaced without disturbing the rest
of the levers. The levers are made with two hooks instead of one as formerly,
by which means I obtain two distinct values out of each spring, which enables
the machine to be used with equal facility for either very heavy or very light
work the second hook being so placed as not in any way to interfere with the
efficiency of the machine.
The chain, like leather, will follow the curve of the lever, but is more durable
and not liable to stretch, and is more easily disconnected and adjusted when
required.

"
Improvements relating to Kenyon's Under-motion" for Operating
the Healds of Looms.
I, WILLIAM HENRY KENYON, of Denby Dale, near Huddersfield, Yorkshire,
Machine Maker, do hereby declare the nature of this invention and in what
inanner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention has reference to what is now commonly called "Kenyon's
under-motion" and for which Letters Patent were granted to me on the 14th
day of June 1883, No. 2960, and again on the 25th day of January 1889,

page_text: No. 1370. The inventions described therein comprised certain levers, which by
spiral springs and cords were connected to the heald shafts for bringing the
healds down after having been lifted in the ordinary manner.
In order that my invention may be more clearly understood I will now make
reference to the accompanying sheet of drawings illustrative thereof, wherein
Fig. 1 is front elevation of "Kenyon's under-motion." A are the bottom jack
levers working upon a fulcrum or stud B carried in the brackets C. The
operating levers A. are lifted by ordinary and well known mechanism to which
they are connected by cords or wires D, but they are drawn down by spiral
springs E, and hitherto these springs have been connected to the levers by a
short length of leather strapping, to the use of which there are many objections;
therefore one object of my present invention is to dispense with the said leather-
connection, and employ instead thereof metal links F, details of which are shewn
in Figs. 2 and 3, the former being end view, and the latter plan view of the said
links. These links F are made of different lengths or sizes, so that when put
together they form a chain of any suitable length, so as to put more or less
pressure on the healds, such said links being coupled together after the manner of
hooks and eyes, and they are interchangeable after having once been connected
together. Instead of forming these links as shown in Figs. 2 and 3 they may be
formed as shewn in Fig. 8. The levers A. are cach made with two hooks G and H
instead of one hook as formerly, by which means I obtain two distinct tensions
out of each spring, which enables the apparatus to be used with equal facility
when weaving either heavy or light goods. The second hook being so placed as
not in any way to interfere with the efficiency or working of the apparatus. The
links F when put together will follow the curve of the lever A in the same manner
as the leather strapping did, but the links are more durable and not liable to
stretch, in addition to which, they can more easily be disconnected and adjusted
when required.
I make the lever A in two parts consisting of the lever proper, and a loose
piece or loop I shewn in detail in Fig. 4. The lever is made with a slot for the
purpose of being placed onto the stud B, and in order to keep it thereon, the loose
piece or loop I is slipped over the edge of the lever in such a manner that its lower
extremity comes into contact with a portion of the stud B as shewn in Fig. 1 and thus
prevents the possibility of the lever getting out of its place. The upper end of
the said loop projects above the circle of the lever A and it is so placed as to
come into contact with a fixed stud J which limits the oscillating movement of the
lever and prevents it from coming into contact with any other part of the apparatus.
The lever A together with the loop I can easily be taken to pieces so as to be
removed and replaced without disturbing the rest of the levers. Instead of using
the loop II may use a pin or stud M as shown in Fig. 9 which answers the same
purpose as the loop I. The cords or wires D hanging down from the healds are
not connected direct to the lever A, but to a link L shewn in end view Fig. 7.
When using two tiers of levers and springs, I prefer to employ one plate K shewn
in elevation in Fig. 5 and edge view Fig. 6, placed about midway on the shaft
so as to keep the tiers rigid and free from oscillation during the time they are at
work.
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 :-
Firstly. The use and employment of interchangeable links for connecting the
levers A to the springs E.
Secondly. The use and employment of interchangeable links of different lengths,
for connecting the lever A to the springs E substantially as herein shewn and
described.
Thirdly. In jack levers such as those described, the formation thereon of two
hooks G and H for purposes described.

page_text: Fourthly. In jack levers the combination therewith of the loop I, employed in
the manner and for purposes described.
