In provements in or relating to Harness Operating Mechanism for
Looms.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street, Birmingham, in the County of Warwick, Civil Engineer,
do hereby declare the nature of this invention to be as follows: —
The invention relates to the devices which are employed, in looms for weaving
sateens and similar fabrics, for the purpose of sustaining the plurality of harness
frames that is used in the production of such fabrics, and also for the purpose
of causing or ensuring the proper reciprocal working of the said harness frames.
The invention relates more particularly to the devices with which the support-
ing and connecting cordings or connections are combined, but does not include the
cams and treadles or other actuating mechanism.
The object of the invention is to provide a simple construction and arrangement
of parts which shall meet all the practical requirements of the uses to which the
same shall be put, and which shall permit of the employment of either the whole
number of harness frames for which the devices are fitted or any smaller number
of harness frames down to two.
The accompanying drawings illustrate the best embodiment of the inven-
tion which has thus far been contrived. Fig. 1 of the drawings
shows in elevation certain portions of a loom for weaving sateens, with the said
embodiment of the invention applied, only such portions of the mechanism of
the loom being shown as are requisite for a proper understanding of the appli-
cation and relation of the invention. Fig. 2 is à view of certain parts, looking
from the right hand side in Fig. 1. Fig. is also a view looking
from the right in Fig. 1 and showing the stand upon which I mount
the levers which are described hereinafter. Fig. 4 is a view showing the said
stand in front elevation. Fig. 5 is a view showing in side elevation the main
or supporting lever to which reference is niade hereinafter. Fig. 6 is a view in
front elevation of the said lever. Fig. 7 is a view in side elevation of the secon-
dary lever and its supporting stud. Fig. S is a view of the said secondary lever
and stud in rear, elevation. Figs. 9 to 14 are views illustrating the various
modes of using the improved devices.

usual cording or straps by means of which the said harness frames are supported,
and 4,4, designate the sheaves over which the said cording or straps pass. The
foregoing parts are or may be of any suitable or desired character and construc-
ion, and the actuating devices by means of which movement is imparted to the
parness frames may be of any usual or suitable character.

On this bracket 5
8, upon which latter in
is mounted lever 9, the same being · known herein as the main
or supporting lever and having capacity to turn upon the said stud as on a
pivot. 10 designates the hole which is formed in the said main or supporting
lever 9 to receive the turned or cylindrical projecting portion of the said stud 8.
To the upper arm of the said main or supporting lever 9 is applied
to turn
a stud 11
which is mounted
on
a pair of harness rolls 12
and 13, which latter are connected to turn together, the rear roll 13 being
slightly the greater in diameter. 14 designates a stud that is applied to the
lower arm of the said main or supporting lever 9, and on the turned or cylin-
drical projecting portion of the said stud 14 the secondary lever 15 is mounted
with capacity to turn. The hole in the said secondary lever 15 which receives
the stud 14 is designated 151. 16 designates a stud that is carried by the lower
arm of the said secondary lever 15, and 17 and 18 designate harness rolls which
are mounted to turn on the said stud, the said rolls being connected to each other
so as to rotate in unison and differing in diameter as in the case of rolls 12 and
13. 19 designates a stud that is applied to the upper arm of the said secondary
lever 15, and having mounted thereon a pair of harness rolls 20 and 21, these last
being connected to turn together and differing in diameter. 22 designates a
second stud applied to the upper arm of the secondary lever 15.
The arrangement which is represented in the drawings is capable of working
with six harness frames. Figs. 1, 2 and 9 show the manner of connecting and
operating the harness cording or straps 3, 3. The latter are in part omitted from
Fig. 2 in order the better to illustrate the devices in which the invention resides
more immediately. With six harness frames in use the front harness frame will
be connected by its cording or straps to the front roll 18, the second harness
frame will be connected to the roll 17, the third harness frame will be connected
to the roll 21, the fourth harness frame will be connected to the roll 20, the
fifth will be connected to the roll 12, and the sixth harness frame will be con-
nected to the roll 13. When it is desired to employ but five harness frames, the
cording will be connected as in Fig. 10, in which latter the rolls 18, 17, 12 and
13 are utilized in connection with the cording or straps from the first, second,
fourth and fifth harness frames respectively, the cording or strap from the third
harness frame being connected with the stud or pin 22. When it is desired to
employ only four harness frames in the loom in which the invention is applied,
the cording or straps from said harness frames may be connected with the
rolls 18, 17 21 and 20 respectively, as indicated in Fig. 11. In this case, if
desired, the main lever 9 may be held in a fixed position by suitable locking
means. If desired, the cording or straps from the four harness frames may be
connected with the rolls 18, 17, 12 and 13 as in Fig. 12, and in this case the
secondary lever 15 will be locked to the main lever 9 so that the said levers
shall turn as one upon stud 8. When it is desired to use only three harness
frames, the cording or straps therefrom will be connected, respectively, with the
rolls 18, 17 and with the stud or pin 22, as in Fig. 13, all carried by the secon-
dary lever 15, the said levers being left free to turn with reference to main
lever 9, and the main lever 9 being, if desired, held locked in a fixed position.
When it is desired to use only two harness frames the cording or straps from the
said harness frames will be connected with the respective rolls of any one pair
of the three pairs of harness rolls, as for instance the rolls 18 and 17 as shown
in Fig. 14, and the two levers 9 and 15 may if desired be locked to render them
immovable.
The devices which have been described above can be used for working four
three or two harnesses without holding or securing the levers if desired.
For

page_text: The
convenience in locking or holding the levers when desired or required, the
devices are usually provided with locking means of convenient character.
drawings show the following means or arrangements for enabling the locking or
holding of the levers to be effected.
The supporting stud 14 for the secondary lever 15 is rendered adjustable in
the direction of the length of such stud in the hole 141, which is formed in the
lower arm of the main lever 9 for the reception of the stud. The stud 14 is
formed with a shoulder, as at 142, at the inner end of the turned or cylindrical
portion on which the secondary lever has bearing, against which shoulder the
boss 152 on the said secondary lever 15 makes contact. On the lower arm of the
main or supporting lever 9, at opposite sides of the hole 141 for the reception
of stud 14, the projecting lips or ribs 144, 144 are provided. The boss 152 on
the rear side of the secondary lever 15 is flattened on its opposite sides, as shown
in Fig. 8, and by adjustment of the stud 14 the said boss may be caused to enter
between the said lips or ribs 144, 144, if desired, and thereby the secondary
lever 15 will be prevented from turning relatively to the main or supporting
Jever 9, so that both of the said levers will turn in manner like unto that of a
single rigid lever about the stud 8. 143 designates the clamping screw by means
of which the stud 14 is held in either of the desired positions of adjustment in
the hole 141 of the lever 9. The stud 8 is adjustable in the direction of its length
through the holo 93 to which it is fitted in the bracket 5, and the said stud 8
is held in the desired position of adjustment in such hole by means of the clamp-
ing screw 94. 95 designates the shoulder on the stud S at the inner end of the
turned or cylindrical portion on which the said main lever 9 is mounted, and
against which shoulder the said lever 9 makes contact. By making proper
adjustment of the stud 8 the portion 91 of lever 9 may be caused when
desired, to enter between the ribs or lips 92, 92, which are formed on the bracket 5
on the opposite sides of the hole 93 in the said bracket, and thereby the lever 9
may be held from turning movement.
When it is desired to work four or three harness frames without holding the
levers, the main or supporting lever 9 may be allowed to fall or turn partly over
under the strain which is transmitted through the harness connections, so that
its lower arm shall extend inwardly in obvious manner. Or the supporting
lever 9 may be omitted and the secondary lever 15 may be applied to the sup-
porting stud 8. In working two harness frames the levers 9 and 15 (in case the
entire arrangement is retained in place) may be permitted to swing inward under
the strain that is transmitted through the harness connections. If the main or
supporting lever 9 is removed, and the secondary lever 15 is mounted on the
supporting stud 8, then in that case the said secondary lever 15 will be allowed
to swing as noted. If desired, both the levers may be removed, and a pair of
rolls corresponding with 17 and 18 may be mounted on the supporting stud S
for two harness work.
It will be observed that all of the pairs of rolls are alike.
Among the advantages of the invention are the facts that the mechanism is
self-contained, and complete for six harness frames or less; that all strap-
pings from the various rolls is in line with the respective harness frames to be
operated; that only one size of double pulley or pairs of rolls requires to be used
in each of the places where the same is represented in the drawings; and that
the mechanism is so designed as that the stud S of the bracket 5 may constitute
the support of either the entire combination of movable levers and rolls, or of a
single lever or of a single double pulley or pair of rolls.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street, Birmingham, in the County of Warwick, Civil 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 follow-
ing statement:―
The invention relates to the devices which are employed, in looms for weaving
sateens and similar fabrics, for the purpose of sustaining the plurality of harness
frames that is used in the production of such fabrics, and also for the purpose
of causing or ensuring the proper reciprocal working of the said harness frames.
The invention relates more particularly to the devices with which the support-
ing and connecting cordings or connections are combined, but does not include the
cams and treadles or other actuating mechanism.
The object of the invention is to provide a simple construction and arrangement
of parts which shall meet all the practical requirements of the uses to which the
same shall be put, and which shall permit of the employment of either the whole
number of harness frames for which the devices are fitted or any smaller number
of harness frames down to two.
The drawings filed with my Provisional Specification illustrate the best embodi-
ment of the invention which has thus far been contrived. Fig. 1 of these drawings
shows in elevation certain portions of a loom for weaving sateens, with the said
embodiment of the invention applied, only such portions of the mechanism of
the loom being shown as are requisite for a proper understanding of the appli-
cation and relation of the invention. Fig. 2 is a view of certain parts, looking
from the right hand side in Fig. 1. Fig. 3 is also a view looking
from the right in Fig. 1 and showing the stand upon which I mount
the levers which are described hereinafter. Fig. 4 is a view showing the said
stand in front elevation. Fig. 5 is a view showing in side elevation the main
or supporting lever to which reference is made hereinafter. Fig. 6 is a view in
front elevation of the said lever. Fig. 7 is a view in side elevation of the secon-
dary lever and its supporting stud. Fig. 8 is a view of the said secondary lever
and stud in rear elevation. Figs. 9 to 14 are views illustrating the various
modes of using the improved devices.
1 designates the loom frame, 2, 2, designate the harness frames 3, 3, designate the
usual cording or straps by means of which the said harness frames are supported,
and 4, 4, designate the sheaves over which the said cording or straps pass. The
foregoing parts are or may be of any suitable or desired character and construc-
tion, and the actuating devices by means of which movement is imparted to the
harness frames may be of any usual or suitable character.
5 designates a bracket which is applied to the arch of the loom frame, it
usually being made adjustable on the said arch in a direction crosswise of the
loom by means of a slot, as 6, formed transversely in the said bracket, through
which slot passes the bolt 7 by means of which the bracket is secured to the arch.
On this bracket 5 is mounted a stud S, upon which latter in turn
mounted a lever 9, the same being known herein as the main
or supporting lever and having capacity to turn upon the said stud as on
pivot. 10 designates the hole which is formed in the said main or supporting
lever to receive the turned or cylindrical projecting portion of the said stud 8.

a

page_text: To the upper arm of the said main or supporting lever 9 is applied
a stud 11 on which is mounted to turn a pair of harness rolls 12
and 13, which latter are connected to turn together, the rear roll 13 being
slightly the greater in diameter. 14 designates a stud that is applied to the
lower arm of the said main or supporting lever 9, and on the turned or cylin-
drical projecting portion of the said stud 14 the secondary lever 15 is mounted
with capacity to turn. The hole in the said secondary lever 15 which receives
the stud 14 is designated 151. 16 designates a stud that is carried by the lower
arm of the said secondary lever 15, and 17, 18, designate harness rolls which
are mounted to turn on the said stud, the said rolls being connected to each other
so as to rotate in unison and differing in diameter as in the case of rolls 12 and
13. 19 designates a stud that is applied to the upper arm of the said secondary
lever 15, and having mounted thereon a pair of harness rolls 20 and 21, these last
being connected to turn together and differing in diameter. 22 designates a
second stud applied to the upper arm of the secondary lever 15.
The arrangement which is represented in the drawings is capable of working
with six harness frames. Figs. 1, 2 and 9 show the manner of connecting and
operating the harness cording or straps 3.3. The latter are in part omitted from
Fig. 2 in order the better to illustrate the devices in which the invention resides
more immediately. With six harness frames in use the front harness frame will
be connected by its cording or straps to the front roll 18, the second harness
frame will be connected to the roll 17, the third harness frame will be connected
to the roll 21, the fourth harness frame will be connected to the roll 20, the
fifth will be connected to the roll 12, and the sixth harness frame will be con-
nected to the roll 13. When it is desired to employ but five harness frames, the
cording will be connected as in Fig. 10, in which latter the rolls 18, 17, 12 and
13 are utilized in connection with the cording or straps from the first, second,
fourth and fifth harness frames respectively, the cording or strap from the third
harness frame being connected with the stud or pin 22.
When it is desired to
employ only four harness frames in the loom in which the invention is applied;
the cording or straps from said harness frames may be connected with the
rolls 18, 17, 21, and 20 respectively, as indicated in Fig. 11. In this case, if
desired, the main lever 9 may be held in a fixed position by suitable locking
means. If desired, the cording or straps from the four harness frames may be
connected with the rolls 18, 17, 12, and 13 as in Fig. 12. In this case the
secondary lever 15 will be locked to the main lever so that the said levers.
shall turn as one upon stud 8. Fig. 12 is a somewhat conventionalized view.
It will be understood that when the levers are thus locked together, the two
levers will stand in line with each other, in the case of the construction herein
shown, and the secondary lever will not be tilted or canted with respect to the
main lever as in Fig. 12. When it is desired to use only three harness
frames, the cording or straps therefrom will be connected, respectively, with the
rolls 18, 17 and with the stud or pin 22, as in Fig. 13, all carried by the secon
dary lever 15, the said levers being left free to turn with reference to main
lever 9, and the main lever 9 being, if desired, held locked in a fixed position.
When it is desired to use only two harness frames the cording or straps from the
said harness frames will be connected with the respective rolls of any one pair
of the three pairs of harness rolls, as for instance the rolls 18 and 17 as shown
in Fig. 14, and the two levers 9 and 15 may if desired be locked to render them
immovable. It will be understood that if the two levers are locked together, az
suggested, they will stand in line with each other, in the case of the present con-
stiuction, instead of the secondary lever being canted or tilted with respect to the
main lever, as in Fig. 14.

devices are usually provided with locking means of convenient character. The

page_text: drawings show the following means or arrangements for enabling the locking or
holding of the levers to be effected.
The supporting stud 14 for the secondary lever 15 is rendered adjustable in
the direction of the length of such stud in the hole 141, which is formed in the
lower arm of the main lever 9 for the reception of the stud. The stud 14 is
formed with a shoulder, as at 142, at the inner end of the turned or cylindrical
portion on which the secondary lever has bearing, against which shoulder the
boss 152 on the said secondary lever 15 makes contact. On the lower arm of the
main or supporting lever 9, at opposite sides of the hole 141 for the reception
of the stud 14, the projecting lips or ribs 144, 144, are provided. The boss 152 on
"the rear side of the secondary lever is flattened on its opposite sides, as shown
in Fig. 8, and by adjustment of the stud 14 the said boss may be caused to enter
between the said lips or ribs 144, 144, if desired, and thereby the secondary
lever 15 will be prevented from turning relatively to the main
lever 9, so that both of the said levers will turn in manner like unto that of a
or supporting
single rigid lever about the stud 8. 143 designates the clamping screw by means
of which the stud 14 is held in either of the desired positions of adjustment in
the hole 141 of the lever 9. The stud S is adjustable in the direction of its length
through the hole 93 to which it is fitted in the bracket 5, and the said stud S
is held in the desired position of adjustment in such hole by means of the clamp-
ing screw 94. 95 designates the shoulder on the stud at the inner end of the
turned or cylindrical portion on which the said main lever 9 is mounted, and
against which shoulder the said lever 9 makes contact. By making proper
adjustment of the stud 8 the portion 91 of lever 9 may be caused when
desired, to enter between the ribs or lips 92, 92, which are formed on the bracket 5
on the opposite sides of the hole 93 in the said bracket, and thereby the lever 9
may be held from turning movement.
When it is desired to work four or three harness frames without holding the
levers, the main or supporting lever 9 may be allowed to fall or turn partly over
under the strain which is transmitted through the harness connections, so that
its lower arm shall extend inwardly in obvious manner.
Or the supporting
lever 9 may be omitted and the secondary lever 15 may be applied to the sup-
porting stud 8. In working two harness frames the levers 9 and 15 (in case the
entire arrangement is retained in place) may be permitted to swing inward under
the strain that is transmitted through the harness connections. If the main or
supporting lever 9 is removed, and the secondary lever 15 is mounted on the
supporting stud 8, then in that case the said secondary lever 15 will be allowed
to swing as noted. If desired, both the levers may be removed, and a pair of
rolls corresponding with 17 and 18 may be mounted on the supporting stud 8
for two harness work.
It will be observed that all of the pairs of rolls are alike. Among the
advantages of the invention are the facts that the mechanism is self-
contained, and complete for six harness frames or less: that all strap-
pings from the various rolls is in line with the respective harness frames to be
operated that only one size of double pulley or pair of rolls requires to be used
in each of the places where the same is represented in the drawings; and that
the mechanism is so designed as that the stud of the bracket 5 may constitute
the support of either the entire combination of movable levers and rolls, or of a
single lever or of a single double pulley or pair of rolls.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improved devices for use in connection with the harnesses of looms for
weaving sateens and similar fabrics, comprising the combination, with the sup-
port, of the main or supporting lever, the secondary lever mounted pivotally on
one arm of the said main or supporting lever, the other arm of the said main or
