Improvements in Dobbies Employed in Looms for Weaving.
I, BERNARD GALBOIS BOULAYE, of 5, Rook Street, York Street, Manchester,
Merchant, do hereby declare the nature of this invention to be as follows:-
The improvements relate to dobbies employed in looms for weaving, and have
for object to provide lattices for such dobbies, the pegs whereof are permanently
attached, while, at the same time, they are capable of ready adjustment into and
out of action, to enable alterations in the pattern to be produced.
In lattices as at present for the most part employed, the same are perforated
with holes, for the reception of pegs which are placed in the required parts of
the lattice, according to the pattern required to be woven, as is well understood.
In carrying out my improvements, I mount upon the lattices pegs of a special
character hereinafter to be described, the number of such pegs corresponding, by
preference, to the number of holes at present employed.
These pegs are hinged or fulcrumed close to their bases or connection with the
lattices, so that they may be turned up or down close to the said lattices, or into
grooves or recesses formed therein.
Thus, when a peg is not required, in lieu of being drawn out of a hole and
removed, as at present, it is simply turned upon its fulcrum or hinge out of action.
By this means, the pegs are always ready to hand, and their adjustment into and
out of position for work is simplified.
Springs or other means may be employed to retain the pegs in either position,
and variations in detail, such as in the character of the hinge joints, may be
made without departing from the peculiar character of the invention.
Dated this 1st day of December 1899.

the same is to be performed, to be particularly described and ascertained in and
by the following statement:-

page_text: Fig. 1 is a portion of a plan view, much enlarged, and Fig. 2 is a cross section
thereof, partly in elevation, of a dobby "lag" arranged in accordance with one
form of my invention, while Fig. 3 is a plan view, similarly enlarged, of a detail
of the improved lag.
The same letters indicate corresponding parts wherever they occur.
In the drawings a hollow form of lag a is shown, and I mount upon the lag a
number of pegs 6 corresponding to the number of holes therefor at present
employed, or as may be desired. These pegs bare tightly held in split sockets c
which are fulcrumed upon the cranked spindle d; but the pegs may be formed
without sockets in one piece of metal, or otherwise, and pivoted direct. Thus
when a peg is not required, instead of being drawn out of a hole and removed,
as at present, it is simply turned upon the fixed spindle d and thereby put out
of action, as indicated by the broken lines in Fig. 2, the upper part of the lag
being slotted to allow of this.
Springs e may be arranged as in Fig. 3 for the purpose of bearing against
the lower ends of the sockets c to retain the pegs in either position.
In Fig. 2 the elevation of the socket and peg which alternate with the socket
and peg shown, is omitted for the sake of clearness, and for the same reason the
intermediate supports for the fixed cranked spindle d are not shown.
h shows a pair of the usual links or eyelets to enable the lag to be connected
to other lags to form a dobby lattice. In lieu of the cranked spindle shown
two straight spindles may be employed, or a short spindle for each moveable peg,
or each moveable peg may be provided with pivots which turn in recesses in the
lag and are held in place by a plate or otherwise; and other variations in detail,
such as the character and arrangement of the hinge joints, the means whereby
the pegs are retained in the required positions, and the material and construc-
tion of the lag, may be made without departing from the peculiar character of
the invention.
said
Having now particularly described and ascertained the nature of my
invention, and in what manner the same is to be performed, I declare that what
I claim is:
In dobby lattices, lags provided with pegs which are capable of being put out

page_text: of action when not required without disconnection from the lags, and also capable
of being retained in the operative and non-operative positions in manner substan-
tially as herein set forth.
