SARAH ELLEN PRIESTLEY, Willow Cottage Liversedge, ANNIE PRIESTLEY,
Fieldhead, Birstall, near Leeds, Married Women, MAILON HIRST, Littletown,
Liversedge, Mechanic, do hereby declare the nature of this invention to be as
follows:
An improved lag the lower part of which is made after the style of a half
circular grate or grates with bars to keep the wheels in their proper place so as
to do away with the tins or so called bushes as used at present also enabling the
pattern plan or design to be altered whilst the lags remain on the loom to any
design the loom will weave.
As used to-day different sized loose tins are placed between each wheel to keep
them in their proper places and are difficult to get off and on we do away with
these tins and substitute the fixed grates thus allowing the wheels to be moved
whilst the lag is on the loom.

We, SARAH ELLEN PRIESTLEY, of Willow Cottage, Liversedge, ANNIE PRIESTLEY,
of Fieldhead, Birstal, near Leeds, Married Women, and MAIILON HIRST, of
Littletown, Liversedge, Mechanic, all in the County of York, do hereby declare
the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to certain improvements in apparatus for placing the
bowls or wheels in position on the lags of looms for weaving pieces to pattern or
design, such design being effected by the position of such bowls or wheels on
the same.
"
Hitherto, the bowls or wheels have been placed in position upon a series of
spindles, such position being secured by the intervention of sleeves or ferrules or
what are technically called "tins of varying lengths. In order to alter the
position of such bowls or wheels as hitherto constructed. it is necessary to uncouple
the links which unite the spindles together and take off the bowls or wheels and
ferrules or tins" and replace the bowls or wheels upon the spindle with sleeves

or ferrules of the required length in order to fill the intervening space, in order to
insure the proper position of the howls or wheels on the lag. Now this operation
involves a good deal of time and attention, apart from the difficulty of insuring such
bowls or wheels being in their proper posi ion, owing to the wear and tear of the
ends of the ferrules or " tins."
Our invention consists in the formation of a lag, consisting of a series of parti-
tions with spaces, in plan, similar to a rate. The formation of such partitions may
be either semi-circular or straight. In the former case the boss of the bowl or
wheel when placed in position rests upon the partitions, prior to the insertion of
the spindle, and in the latter case, the bowl rests upon the hollow part of the
cylinder prior to the insertion of the spindle.
By such means, it is only necessary for the operator to place the bowls or wheels
in the required position within any of the spaces made by the partitions. and
then insert the spindle, the sleeves or ferrules of varying lengths, hitherto in
use, being entirely dispensed with.
Another advantage of our improvement consists in the fact that, it is not
necessary to disconnect the links which bitherto connected the ends of the spindles
of the lags together, as, we connect together the ends of the frame of the grates
forming the lags by hinges, and pass the spindle through one end of the frame.
then through the bosses of the bowls or wheels and then through the other end
of the frame. The ends of the spindles are drilled and a split pin inserted in order
to retain the spindles in position.
In explaining our invention in detail, reference is made to the accompanying
drawings in which Fig. 1 represents a plan of two of our improved lags hinged
together at the ends.
Fig. 2 is a cross section of Fig. 1 through line a, b, showing the semi-circular
partitions.
Fig. 3 an end view of Fig. 1.
Fig. 4 is a plan, of one lag only, showing the same with straight partitions,
and
Fig. 5 is a cross section of Fig. 4 through line e,.
The lag frames or grates A. are hinged together at each end O, by links B.
placed in the recesses C, and secured therein by pins D. The frames or grates A,
are divided by partitions or cross bars E. flat on the top at T. and semi-circular
below in order that the spindle may pass in clear of the partitions as shown at H,
or, the partitions or cress lars may extend from side to side in a more direct
manner with a hole bored in the centre of each partition for the spindle G, as
shown at J, Fig. 5 in either ease. the bowls or wheels F. F, F. are placed in the
spaces S. S. S. in order to make the design and secured therein by the passing
of the spindle G, through one end O. of the lag frame A, and centre of the bowls or
wheels in their respective positions and through the other end 0, of lag frame, the
spindle is then secured in such position by split pins passing through the ends of
the spindles or other like means.
The lag frames or grates A. are mounted upon evlinders of ordinary construction.
and are operated in the ordinary manner, the bowls or wheels F, F, F. operate
the horizontal levers, which through the ordinary mechanism operate the warp
threads.
By constructing the lag frames or grate: A, as above described and shown, when
the pattern or design is required to be alter d, the same may be accomplished
without removing the lag frames or grates from the loom, that is to say, by with-
drawing the spindles G. from the frames, the bowls or wheels F. F. F. are liberated
and may then he rearranged in the spaces S, between the partitions E, in order to
make the pattern and secured in the respective spaces S, on reinstating and
securing the said spindles.
It is well known, that in use. the logs are secured together. forming an endless
chain, which is operated by the revolving of a cylinder which is divided into
compartments and which in section represents a chain wheel.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, we declare that what
we claim is:-
Lag frames or grates A, provided with spaces or recesses which admit of the
bowls or wheels F, F, F, being placed therein, hinged together at the ends,
arranged substantially in the manner and for the purpose as hereinbefore set
forth.
