Improvements in or connected with Loom Pattern Mechanism.
I, JAMES HILL of 35 Ethel Street Keighley in the County of York, Mechanical
Engineer do hereby declare the nature of this invention to be as follows, that is to
say:
It relates to improvements in pattern surfaces formed of wheels or pulleys
mounted on metal chains as also to those pattern surfaces known as lags and pegs,
one or the other of either of these classes being usually employed for controlling
and regulating the movements of the loom's heddles and shuttle-boxes through the
medium of other well known operating mechanism, and the object of this invention
is to produce metal pattern chains as also lags with pegs that shall at all times
bear the full complement of parts for producing any movement in the heddles or
shuttle-boxes without necessitating the detachment, displacement or addition of
any of their metal pulleys or of any of their pegs, so that by having a pattern
chain of the desired length or consisting of the desired number of links or lags
with their respective pulleys and pegs constructed in accordance with this inven-
tion any desired movement may be effected by adjusting said pulleys (as I shall
continue to style my improved equivalent for the pulleys) or said pegs to be in
position for extending radially from the centre of their operating cylinder or to be
at about right angles to this position.
To attain this object in connection with the pattern surfaces consisting of metal
chains and pulleys, instead of making use of complete pulleys I employ only
portions of them, said portion being the entire hub and part of the rim, so that
when mounted upon the bar or rod of the chain they may be made to extend at
right angles to the links or to be about parallel therewith, and to hold them in
these positions the hubs have projections and recesses for coupling together, that
is to say the projections on one side of the hub of one pulley fit into the recesses
in the other side of its neighbour pulley and the two end pulleys have their
projections and recesses joined or fitted with corresponding projections and recesses
carried by a hub formed on their adjoining links.
Square holes may be formed in the pulleys so that square shafts may be employed
for holding same instead of the hubs of said pulleys having recesses and projec-
tions for this purpose, however in this case all the pulleys would have to be
detached for adjustment. Again as an alternative method of locking the pulleys
a separate pin passing horizontally through the whole series on each bar or rod,
locking those that are erect as well as those that are recumbent in their respective
positions, however this method does not lend itself to facilitating their adjustment
as does the method first before described.
The operating cylinder has its peripheral surface made to receive these hubs so
that they may rest thereon in an appropriate manner to withstand any forces they
may have to overcome when in operation.
Guide pieces are mounted on the framework to keep the links in their proper
operating positions as they pass over their cylinder.
To accomplish the object of this part of my invention when lags and pegs are to
be employed, I make use of the well known class of wooden lags, however instead
of using pegs that are merely to be inserted into the holes to effect their attachment
thereto; I so form them that to each hole in the whole series of holes a peg may
be hinged in such a manner that at one time it may lay flat upon the lag while at
another it may stand erect thereon. To effect this I make an elongated hole or
slot in the peg through which the hinging-pin passes and by which the peg may

page_text: be moved radially from as well as rotated about its said hinging-pin. By forming
cross grooves in the lag to receive the peg in its flat or reclining position thereon,
when the said peg is moved so that it crosses the hole in the lag it is held out of
its operating position, while when moved and inserted into its vertical hole in the
lag it is held in its erect and operating position.
Instead of the peg being hinged to its lag by having an elongated hole as above
described it may be hinged thereto by having a circular hole near one of its
extremities and having a tubular piece to fit over and slide upon it to hold it in its
erect or reclining positions as will readily be understood.

Improvements in or connected with Loom Pattern Mechanism.
I JAMES HILL of 35 Ethel Street Keighley in the County of York, Mechanical
Engineer, 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 pattern surfaces formed of wheels or pulleys
mounted upon metal chains as also to those pattern-surfaces known as lags and
pegs, one or the other of either of these classes being usually employed for con-
trolling and regulating the movements of the loom's heddles and shuttle-boxes
through the medium of other well-known operating mechanisms, and the object of
this invention is to produce metal pattern chains as also lags with pegs that shall
at all times bear the full complement of parts for producing any movement in the
heddles or shuttle-boxes without necessitating the detachment, displacement or
addition of any of their metal pulleys or of any of their pegs, so that by having a
pattern chain of the desired length or consisting of the desired number of links
or lags with their respective pulleys and pegs constructed in accordance with this
invention any desired movement may be effected by adjusting said pulleys (as I
shall continue herein to style my improved equivalents for the pulleys) or said
pegs to be in position for extending radially from the centre of their operating
cylinder or to be at about right angles to this position.

Similar letters and figures of reference indicate similar parts throughout the
several views.
To attain the object of this invention as regards pattern surfaces_consisting of
metal chains and pulleys, instead of making use of complete pulleys I employ only
portions of them, said portions being the entire hub a and part of the rim b, so
that when mounted upon the bar or rod c (which I preferably form hollow, as a
tube and as shewn by Fig. 3) of the chain they may be made to extend at about
right angles to the links d so that they may extend radially from or be con-
vergent in the centre e of their operating cylinder f as they are brought thereby
into operating position in order that they may place other parts into operation or
leave same inoperative as is well understood. Or instead of the rims b being
turned from their operative positions when extending radially from the centre e to
their inoperative positions when they are convergent in said centre, as shewn at b²
Fig. 2, they may be turned down to be about parallel to said links d as is shewn
at band di Fig. 17.
To hold these pulleys in these said positions their hubs a have projections a¹
and recesses a² for coupling together, that is to say the projections a¹ on one side
of the hub a of one pulley fit into the recesses a² in the other side of the hub a
of its neighbour pulley and the two end pulleys have their projections a¹ and
recesses a² joined or fitted into and with corresponding recesses d² and projections d³
carried by a hub formed on their adjoining links d or d*.
To allow the adjustment of these pulleys it is only necessary to loosen the end
binding screw & or a sufficiently to enable any one of said pulleys to be uncoupled
from the rest as will readily be understood.
Square holes g may be formed in the hubs a of the pulleys and links & so that
a square shaft h may be employed for holding same (see Figs. 7, 8, 9 and 10)
instead of said hubs a having recesses and projections for this purpose, however in
this case all the pulleys would have to be detached for adjustment or re-
arrangement.
Again as an alternative method of locking the pulleys with their adjoining links,
a separate pin 2 passing horizontally through the whole series of the hubs a on
each bar or rod c, locking those that are erect, as those at 2 and 3 Figs. 11 and 17
as well as those that are recumbent, as the one at 4 Fig. 17, or pendent as are
those at 5 and 6 Fig. 11 in their respective positions by said pin c² passing also
through the end links d, however this method does not lend itself to facilitating the
adjustment of the pulleys as does the method first before described.
The suppleness of the pattern chain composed of each of the forms of the links d
hereinbefore described is secured or obtained by the holes do, which are at the
opposite ends of said links to those ends by which they are coupled to the hubs of

page_text: the pulleys, being made circular to fit loosely on or so that they will swivel about
the pins of the adjoining links.
The operating cylinder has its peripheral surface made, by having the ribs f¹
arranged to extend somewhat tangentially to its axial shaft in order to conform to
the shape and position of the pulleys as shewn by Fig. 27, co that they may rest
thereon or against same in an appropriate manner to withstand any forces they
may have to overcome when in operation.
Guide pieces are mounted on the framework ¹ to keep the links d in their
proper operating positions as they pass over their cylinder f whether they are
going in a forward or backward direction.
To accomplish the object of my invention when lags and pegs are to be employed,
I make use of the well known class of wooden lags, however instead of using pegs
that are merely to be inserted into the holes to effect their attachment thereto, I
so form them that to each hole in the whole series of holes a peg may be hinged
in such a manner that at one time it may lay flat upon the lag while at another
it may stand erect thereon.
To effect this I make an elongated hole or slot in the peg / through which the
hinging-pin m passes, and by which (slot 1) the peg is permitted to be moved
radially from as well as rotated about its said pin m. By forming, cross grooves n¹
in the lag n to receive the peg 7 in its flat or reclining position thereon, when the
said peg is moved so that it extends across the hole in the said lag n it is held
by its pin m out of its operating position, while when moved and inserted into its
vertical hole in the lag n, it is by thus being inserted therein, held in its erect and
operating position.
Instead of the peg being hinged to its lag n by having an elongated hole /
as above described it may be hinged thereto by having a circular hole 12 (see
Fig. 26) near its lower extremity for its hinging pin m to pass through and having
a tubular piece or sleeve p to fit over and slide upon it to hold it in its erect
position by said sleeve p being slided upon it and inserted or forced down into
the hole in the lag, or in its reclining position by said sleeve p being slided to
extend across said hole in the lag n.
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.
1. In pattern surface mechanism a pulley formed so that it may be made to
assume an operative or inoperative position without being detached from the bar or
rod upon which it is mounted substantially as herein set forth and described.
2. In pattern surface mechanism the method of constructing the series of pulleys
that form the indicating mechanism so that each pulley in the series is or may be
coupled to, in order to be held by, its neighbour pulley substantially as herein
specified.
3. In pattern surface mechanism the arrangement and construction of the pulleys
forming the indicating mechanism so that they may be securely held in position
by being coupled or attached to their end chain-links substantially as herein
specified.
4. In pattern surface mechanism a supplementary bar or pin, as the pin c,
arranged so that it will couple or bind the series of pattern pulleys to their end
chain-links in order that same may be thereby held in their proper respective
position substantially as set forth.
5. The general arrangement and combination of parts forming the pattern surface
mechanism, and a pattern cylinder, as also other parts used in connection with same
substantially as herein specified.
6. In pattern surface mechanism a peg formed with an elongated slot and
means for hinging same to a peg-lag substantially as herein set forth and
described.

page_text: 7. In pattern surface mechanism a hinged-peg having a moveable sleeve for
maintaining same in position substantially as herein specified.
