PROVISIONAL SPECIFICATION.
Improvements in Lags and Pegs or Pattern Surfaces, applicable for
use in connection with the Shedding Mechanism of Looms.
We, JAMES HILL of Ethel Street Keighley in the County of York, Engineer
and EDWARD HILL of the same place Draughtsman, do hereby declare the nature
of this invention to be as follows, that is to say :-
It relates to improvements in the construction of lags and pegs, such as are used
as pattern surfaces in connection with the shedding mechanism of looms, and
consists of forming these lags and pegs in such a manner that they will afford
considerable advantages for being altered or changed from the production of one
design to that of another.
To attain this object we form the lag of sheet metal, which we fold in such a
manner as to produce a hollow lag having a contour or external shape corresponding
somewhat with the shape of the well known wooden ones at present in use, along
the upper surface of this lag being formed a slot or niche communicating with the
interior of said lag.
The pegs are preferably formed of metal (though wooden pegs of the proper
shape might be employed) their lower parts being made to fit within the cavity of
the lag while their projecting parts extend through the niche or slot beyond the
outer upper surface of the lag to produce the desired effect in the shedding
mechanism as is well understood.
Blank parts, that is to say parts formed to correspond with the shape of the
lower part of these pegs but having no projecting part to extend beyond the surface
of the lag, may be employed for spacing said properly formed pegs in order
to maintain same in proper position or in their respective paths of motion when
in usc.
Instead of the effective and the bottom or base part of the pegs being made
integral as above described the upper part may be formed so that it may be hinged
to the lower part in order that when it is not desired to be in its erect position
relatively with its lag it may be turned down to extend within said lag and so be
in an inoperative position while yet its bottom part serves as a spacing medium for
the effective or operating pegs.
When all the pegs and their spacing parts are placed within the hollow lag a
plug or hinged piece at the ends of the lag are driven or moved into position thus
forcing the pegs against each other and into their proper respective positions for
performing their functions in the machine.
Dated this 3rd day of September 1891.

COMPLETE SPECIFICATION.
Improvements in Lags and Pegs or Pattern Surfaces, applicable for
use in connection with the Shedding Mechanism of Looms.
We JAMES HILL of Ethel Street Keighley in the County of York, Engineer
and EDWARD HILL of the same place Draughtsman, 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, that is to say :-
It relates to improvements in the construction of lags and pegs such as are used

page_text: as pattern surfaces in connection with the shedding mechanism of looms, and
consists of forming these lags and pegs in such a manner that they will afford
considerable advantages for being altered or changed from the production of one
design to that of another.
In the accompanying sheet of drawings
Figs. 1 and 2 are respectively side and top views of a lag with its complement of
pegs or blanks as hereinafter described.
Fig. 3 is sectional end view of parts shewn by Fig. 1.
Fig. 4 is side, top and end views shewing the lag in detail.
Fig. 5 shews the sheet-metal blank before it is folded to form the lag.
Fig. 6 is a sectional top view shewing the method of attaching the joining links
to the lag.
Figs. 7 and 8 are drawings in detail shewing the pegs and blanks hereinafter
described.
Fig. 9 is a detail drawing hereinafter referred to.
Fig. 10 is a detail drawing shewing the method of forming a metal spacing piece
or blank for supporting the metal peg shewn by Fig. 11.
Fig. 12 shews the blank part from which the spacing piece shewn by Fig. 10 is
formed.
Fig. 13 is side view of a portion of a lag shewing the method of mounting
therein the pegs and spacing pieces shewn by Figs. 10 and 11.
To attain the object of our invention we form the lag a of sheet metal, which we
fold in such a manner as to produce a hollow lag having a contour or external
shape corresponding somewhat with the shape of the well known wooden ones at
present in use, along the upper surface of this lag a being formed a slot or niche b
communicating with the interior of said lag a.
The pegs are preferably formed of metal as hereinafter described, although
wooden pegs of the proper shape may be employed. These pegs have their lower
parts made to fit within the cavity of the lag a which forms the framework for
holding them in position together, while their projecting parts c¹ extend through
the niche or slot & beyond the outer upper surface a¹ of the lag a to produce the
desired effect in the shedding-mechanism as is well understood.
Blank parts d, that is to say parts formed to correspond with the shape of the
lower part of these pegs, but having no projecting part to extend beyond
the surface a¹ of the lag a, are employed for spacing said properly formed pegs in
order to maintain same in proper position as shewn by Fig. 1, so that they may
travel with the lag a in their respective and desired paths of motion when in use.
Instead of the effective or projecting part c¹ and the bottom part of the pegs
being made integral as above described, the upper part may be formed so that it
may be hinged to the lower part as is the upper part to the lower part f
(Figs. 1, 11, 12 and 13). The part is stamped out of sheet metal in the blank
form shewn by Fig. 12, after which it is bent or folded into the shape shewn by
Fig. 10 so that it may be slided within the hollow lag a to maintain the part fin
position whether it is made to stand erect or to be in its pendent position shewn in
broken lines Fig. 13. By forming the parts fand I as above described the part f
may be turned down or arranged to be in its pendent position when not desired to
be operative, the mere loosening of the parts to allow space for the turning down
of this part being all that is necessary to effect their arrangement in position for
producing any design that may be desired. The bottom parts f¹ in all cases secure
the relative lateral position of the parts f, the distance from one part to another
being equal to the breadth of the party.
a
When all the pegs c, c' and parts d'or f¹ and f, are placed within the hollow lag
they are held in position by the plug piece g which is secured by the pin so that
all and each of the operating pegs are maintained in their respective positions for
performing their functions in the machine.
The linking or coupling together of the lags a is secured by the links k being
inserted within a bulged part of the lag a as shewn by Fig. 6. The well known

page_text: kind of coupling rings being further employed for coupling these links k to form a
complete chain of pattern lags.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is.
1. A metal frame for holding pegs and spacing parts to form a peg-lag or pattern
surface substantially as herein specified.
2. The combination of pattern-surface pegs having base parts for determining
their relative positions, base parts for interchanging with said pattern-surface pegs,
and a metal frame or hollow lag for holding said pegs and base parts substantially
as specified.
3. The combination of a hollow lag, a hinged peg and a folded support for
maintaining said peg in or out of its operating position substantially as herein set
forth.
4. The method of forming or constructing lags and pegs for pattern surfaces
substantially as herein set forth and described.
