page_text: I, LOUIS WILLEMAIN, of No. 9, Exchange Street, in the Town of Westfield,
County of Hampden and State of Massachusetts, United States of America,
Machinist, do hereby declare the nature of this invention to be as follows:-
This invention relates to looms and particularly to a new and improved con-
struction of loom-temples, the object of the invention being to provide a temple
which can be used on the most delicate fabric without injuring it or picking
up the threads thereof, and which can readily be adjusted to give more or less
transverse draft to said fabric and which can be adjusted to grip said fabric
with sufficient force to prevent it from yielding to any strain transverse to the line
of its movement in passing through the loom, but in which the grip of the
device on said fabric to hold it against said transverse strains does not in
the slightest degree impede the movement of said fabric through the machine.
The invention consists in the construction as hereinafter set forth.
In carrying out the invention I provide an annular case having an arm of any
suitable form to permit of securing it to the loom in a proper position, said arm
lying in a plane below the top of said case to give free passage to the fabric
across the top of said case. A suitable lug extends outward from the side of the
case, at right angles to said arm; said case, lug, and arm being preferably made
integral, and these and all other parts of the device are made of any suitable
metal.
A ring for receiving the parts of the temple co-acting with those parts con-
tained in the case, is bolted to said lug, by a bolt, said ring being provided with
a second lug similar to the first mentioned lug for that purpose. Said bolt
passes through both lugs and is provided with a head countersunk in the underside
of the first lug and with a nut bearing on the upper surface of the second lug.
The upper end of said bolt is slotted transversely whereby it may be turned with
a screw-driver when the nut is loosened, and the head of the bolt is provided with
a pin located near the edge of said head.
Said lugs are so constructed that when they are bolted together the contiguous
edges of the ring and the case will be separated by the space through which the
fabric passes.
Lying within the lowest part of the case is the circular cam-plate provided with
an annular groove in its periphery. The diameter of the top of said cam-plate
exceeds somewhat the diameter of the lower part thereof, and said case is made with
two internal diameters corresponding substantially with those of said cam-plate,
thus forming within said case a shoulder on which the projecting edge of the
cam-plate rests.
At a point in said annular groove which would lie substantially under the edge

page_text: of the fabric when the latter is in proper position in the space the base of said
groove is inclined upward an easy curve from the lever of said base leading up to
the summit of said incline and from thence down to the level of the base again,
the angles of the said ascent and descent being substantially the same; and in the
part of said cam-plate forming the top of said annular groove lying over said
incline a slot is cut concentric with the cam-plate and of substantially' the same
width as the depth of the groove and extending only over that part of said groove
occupied by said upwardly inclined part thereof.
On the edge of said cam-plate, coinciding with the highest part of the incline,
is a trough extending through a suitable slot in the side of the case, and provided
with a slot radially located in 'said tongue relative to the centre of said cam-
plate, The slot in the case, through which the tongue passes, is made wide
enough to permit said tongue to be swung laterally to either side of the centre
of the bolt, whose centre coincides with the centre of the slot.
The slot in said tongue receives the pin in the. head of the bolt whereby, by
turning said bolt, the highest point of said incline may be swung to one side or
the other of a line drawn at right, angles to the line of movement of the fabric
through the temple, through the axis of said cam-plate.
The case is provided with a central boss, therein and said cam-plate has its
centre turned out to fit said boss and may be rotated more or less therein with its
edges free from the sides of said case.**
case.
1+
The plunger-plate is a circular plate adapted to fit in the case on the top
-of the-cam-plate, and the central perforation therein fits the boss in said case
closely enough to prevent contact between the edges of said plunger-plate and the
Said plate is provided with a row of holes concentrically arranged thereon
and extending therethrough-at-right angles to the plane of rotation of said plate.
The centres of said row of holes coincide with the centre of the slot in the top of
said cam-plate. The holes receive the plungers which are of a length substantially
equal to the thickness of the plate. Said plungers are provided with the heads
on the ends thereof which bear on the cam-plate the holes in said plates being
counterbored far enough to receive said heads and permit them to move endwise
therein for a certain distance. After said holes have been bored and counter-
bored in that end thereof lying next to the cam-plate, an annular groove is
turned in that side of the plunger-plate whereby the thin metal wall between
the counterbored ends of said holes will be cut away for a certain depth.
When the cam-plate has been put in place in the case a sufficient number of
hard steel balls of slightly less diameter than said groove, are put into the said
groove through the slot to fill said groove; and the plunger-plate having the
plungers thereon, is then laid in said case on the top of said cam-plate. When
the balls are placed in the groove, those that rest on the upwardly inclined part of
said groove, will project through the slot and above the surface of the said cam-plate;
and, therefore, when the plunger-plate is placed in position on said cam-plate,
the plungers lying over said slot will be forced upward so that their upper ends will
project above the upper surface of the plunger-plate to practically the same extent
that the balls project above the surface of the plate.
As the walls between the holes in the plunger-plate have been cut away, as
stated, by the groove, which has a depth somewhat in excess of the distance
which the balls project above the cam-plate, it follows that said plunger-plate
may be rotated without hindrance, and that when said plate is so rotated, the
bases of the plungers are successively caused to ride up on the balls lying on
the incline, thus forcing the upper ends of said plungers outward
above the surface of said plunger-plate.
The upper ends of these plungers, as they are forced upward, impinge, when
near the summit of the incline, against the surface of a circular plate supported
to rotate freely in the ring, and said plate is concentric with, and parallel with,
the contiguous face of the plunger-plate.
A ring of some yielding material, such as rubber, is applied to said plate and

page_text: covers that part of it extending from the edge thereof inward for a distance a
little greater than the diameter of the plungers. Said circular plate is held in
proper position by screws entering the hub of a shell which is screw-threaded to
enter the threaded interior of the ring, and said shell is made to project far enough
out of said ring to permit of locating a check-nut thereon, the position of which
will determine the distance between the faces of said circular plate and said
plunger-plate.
To obviate the possibility of disturbing the adjustment of the check-nut, a
part of the hub of the shell on the outside of said shell, is made square, and a
plate having a slightly larger diameter than said check-nut, has a square perfora-
tion through it which fits over the square end of the hub of the shell; and after
said check-nut has been set, the said plate is placed in position and fixed there
by a screw and the shell can then be screwed into or out of said ring by grasping
the said plate whose edge is knurled and rounded for the purpose, without being
liable to disturb the adjustment of the check-nut. The edge of the ring is made
to extend somewhat below the surface of the plate to prevent contact between the
face of plate and the fabric.
The adjustment of the face of the plate relative to the ends of the plungers in
their outermost position, is a very delicate one, as it determines the force with which
the fabric shall be gripped between said plungers and the ring of the plate.
It is obvious that as the point of contact of said plungers with said plate is
to one side of the center of the plunger-plate and said plate, that the fabric
gripped between the said two plates may be freely drawn through the temple, but
that any attempt to draw said fabric transversely to said direction would be
impossible as long as the fabric is gripped between said two plates.
It is understood, of course, that these temples are placed on each side of the loom
to grip each edge of the fabric and are placed opposite each other; and it has been
stated that the fabric is gripped before the plunger arrives at the highest point of
said incline, and said grip is maintained on the fabric for an equal distance
each side of a line drawn through the centre of the temple and through the bolt,
if the centre of the slot in the tongue coincides with the abovementioned centre-
line. That is to say, said fabric is gripped at a point on one side of said line
equi-distant from said line with the point on the other side at which said grip
is released.
Thus, by moving said tongue right or left, the point of gripping engagement of
said fabric may be varied relative to the point of release and thus more or less
transverse draft may be given to the temple as may be desired.
I provide a thin rubber ring similar to the ring above referred to except that
this ring is provided with short projections which are adapted to enter depressions
in the tops of the plungers when said ring is placed on the plunger-plate in a
position opposite the ring on plate.
The purpose of this ring is to protect a very thin material from being injured
by the ends of the plungers being forced against it.
The great advantage of a loom-temple which in nowise disfigures the fabric,
however light it may be, and one in which the adjustment for lateral draft on said
fabric is so simple and easy to operate as is the construction embodied in this
invention, is very apparent.
It is obvious that if desired more than one row of plungers may be employed,
and that such construction would be clearly within the scope of this invention.
Such a construction might be desirable in temples designed to be used on looms
weaving exceptionally heavy fabrics.

I, LOUIS WILLEMAIN, of No. 9, Exchange Street, in the Town of Westfield,
County of Hampden and State of Massachusetts, United States of America,
Machinist, 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:-
This invention relates to looms and particularly to a new and improved con-
struction of loom-temples, the object of the invention being to provide a temple
which can be used on the most delicate fabric without injuring it or picking
up the threads thereof, and which can readily be adjusted to give more or less
transverse draft to said fabric and which can be adjusted to grip said fabric
with sufficient force to prevent it from yielding to any strain transverse to the line
of its movement in passing through the loom, but in which the grip of the
device on said. fabric to hold it against said transverse strains does not in
the slightest degree impede the movement of said fabric through the machine.
The invention consists in the construction as fully hereinafter set forth and
particularly pointed out in the claims.
In the drawings forming part of this Specification,-
Figure represents-a-temple in top_plan_view, constructed according to this
invention, a part thereof being broken away.
Figure 1 is a perspective view of a thin flexible disk.
Figure 2 is a sectional view of the temple taken on line 2-2, Figure 1.
Figure 3 is a sectional view of the temple taken on line 3-3, Figure 1.
Figure 4 is a plan view of a cam-plate.
Figure 5 is a perspective view of the same in a different position.
Figure 6 is a perspective view of the circular plunger-plate and one plunger
which is separated from said plate.
Referring to the drawings, A represents an annular case having an arm B of any
suitable form to permit of securing it to the loom in a proper position, said arm
lying in a plane below the top of said case A to give free passage to the fabric C,
across the top of said case. A suitable lug A¹, extends outward from the side
of the case A, at right angles to said arm B; said case, lug, and arm being
preferably made integral, and these and all other parts of the device are made of
any suitable metal.
A ring for receiving the parts of the temple co-acting with those parts
contained in the case A, is bolted to said lug A¹, by a bolt 2, said ring being
provided with a lug B₁ similar to the lug A' for that purpose.
Said bolt passes through both lugs and is provided with a head 3 countersunk
in the underside of the lug A' and with a nut 4 bearing on the upper surface of
the lug B¹.
The upper end of said bolt 2 is slotted transversely whereby it may be turned
with a screw-driver when the nut 4 is loosened, and the head 3 of the bolt is
provided with a pin 5 located near the edge of said head, as shown in Figures 1
and 5.
Said lugs A and B are so constructed that when they are bolted together the
contiguous edges of the ring D and the case A will be separated by the space a,
through which the fabric C passes, as shown.
Lying within the lowest part of the case A is the circular cam-plate (see
Figure 5) provided with an annular groove 7, in its periphery. The diameter of
the top of said cam-plate exceeds somewhat the diameter of the lower part thereof,

page_text: and said case A is made with two internal diameters corresponding substantially
with those of said cam-plate 6, thus forming within said case a shoulder 8 on
which the projecting edge of the cam-plate rests, as shown in Figures 2 and 3.
At a point in said annular groove 7, which would lie substantially under the
edge of the fabric when the latter is in proper position in the space a, the base
of said groove is inclined upward (as indicated by 9) an easy curve from the
level of said base leading up to the summit of said incline and from thence down
to the level of the base again, the angles of the said ascent and descent being
substantially the same; and in the part of said cam-plate 6 forming the top
of said annular grove 7 lying over said incline 9, a slot 10 is cut concentric with
the cam-plate 6, and of substantially the same width as the depth of the groove 7,
and extending only over that part of said groove occupied by said upwardly
inclined part thereof.
On the edge of said cam-plate, coinciding with the highest part of the incline 9,
is a tongue 12, extending through a suitable slot in the side of the case A, and
provided with a slot 12 radially located in said tongue relative to the center of
said cam-plate. The slot in the case A, through which the tongue 12 passes, is
made wide enough to permit said tongue to be swung laterally to either side of the
center of the bolt 2, whose center coincides with the center of the slot 12".
The said slot 12", in said tongue 12, receives the pin 5 in the head 3 of the
bolt 2, whereby, by turning said bolt, the highest point of said incline 9 may
be swung to one side or the other of a line drawn at right angles to the
line of movement of the fabric through the temple, through the axis of said
cam-plate 6.
The case A is provided with a central boss b, therein and said cam-plate 6 has its
center turned out to fit said boss and may be rotated more or less therein with
its edges free from the sides of said case A.
The plunger-plate 13, shown in perspective in Figure 6, is a circular plate
adapted to fit in the case A on the top of the cam-plate 6, and the central
perforation therein fits the boss b in said case closely enough to prevent contact
between the edges of said plunger-plate and the case. Said plate 13 is provided
with a row of holes 14 concentrically arranged thereon and extending therethrough
at right angles to the plane of rotation of said plate. The centers of said row
of holes coincide with the center of the slot 10 in the top of said cam-plate. The
holes 14 receive the plungers 15 which are of a length substantially equal to the
thickness of the plate 13. Said plungers are provided with the heads 15 on the
ends thereof which bear on the cam-plate 6, the holes 14 in said plate 13 being
counterbored far enough to receive said heads and permit them to move endwise
therein for a certain distance. After said holes 14 have been bored and counter-
bored in that end thereof lying next to the cam-plate 6, an annular groove 14ª is
turned in that side of the plunger-plate in the position shown in Figure 6, whereby
the thin metal wall between the counterbored ends of said holes will be cut
away for a certain depth.
When the cam-plate 6 has been put in place in the case A, a sufficient number of
hard steel halls 16 of slightly less diameter than said groove 7, are put into the
said groove through the slot 10, to fill said groove; and the plunger-plate 13
having the plungers 15 thereon, is then laid in said case on the top of said cam-
plate 6.
When the balls 16 are placed in the groove 7, those that rest on the upwardly
inclined part 9 of said groove, will project through the slot 10 and above the
surface of the said cam-plate 6; and, therefore, when the plunger-plate is placed in
position on said cam-plate, the plungers 15 lying over said slot 10 will be forced
upward so that their upper ends will project above the upper surface of the
plunger-plate 13, to practically the same extent that the balls 16 project above the
surface of the plate 6.
As the walls between the holes 14 in the plunger-plate have been cut away, as
stated, by the groove 14, which has a depth somewhat in excess of the distance

page_text: which the balls 16 project above the cam-plate 6, it follows that said plunger-plate
may be rotated without hindrance, and that when said plate is so 1otated, the bases
of the plungers 15 are successively caused to ride up on the balls lying on the
incline 9, thus forcing the upper ends of said plungers outward above the surface
of said plunger-plate.
The upper ends of these plungers 15, as they are forced upward, impinge,
when near the summit of the incline 9, against the surface of a circular plate 17
supported to rotate freely in the ring D, and said plate is concentric with, and
parallel with, the contiguous face of the plunger-plate 13.
A ring 17" of some yielding material, such as rubber, is applied to said plate 17,
and covers that part of it extending from the edge thereof inward for a distance
a little greater than the diameter of the plungers 15.
Said circular plate 17 is held in proper position by screws 18 entering the hub
of a shell 19, which is screw-threaded to enter the threaded interior of the ring D,
and said shell is made to project far enough out of said ring to permit of locating
a check-nut 20 thereon, the position of which will determine the distance between
the faces of said circular plate 17 and said plunger-plate 13.
To obviate the possibility of disturbing the adjustment of the check-nut 20,
a part 19 of the hub of the shell 19, on the outside of said shell, is made square,
as shown in dotted lines in Figure 1, and a plate 22, having a slightly larger
diameter than said check-nut, has a square perforation through it which fits
over the square end 19" of the hub of the shell 19; and after said check-nut 20
has been set, the said plate 22 is placed in position and fixed there, as shown in
Figure 2, by a screw 28, and the shell-19 can then be screwed into or out of said
ring D by grasping the said plate 22, whose edge is knurled and rounded-for-the-
-purpose, without being liable to disturb the adjustment of the check-nut 20.
The edge of the ring D is made to extend somewhat below the surface of
the plate 17, as at D, to prevent contact between the face of plate 17 and the
fabric.
The adjustment of the face of the plate 17 relative to the ends of the plungers in
their outermost position, is a very delicate one, as it determines the force
with which the fabric shall be gripped between said plungers and the ring 17", of
the plate 17.
It is obvious that as the point of contact of said plungers 15 with said plate 17
is to one side of the center of the plunger-plate 13 and said plate 17, that
the fabric gripped between the said two plates may be freely drawn through the
temple in the direction indicated by the arrows in Figure 1, but that any attempt
to draw said fabric transversely to said direction would be impossible as long as
the fabric is gripped between said two plates.
It is understood, of course, that these temples are placed on each side of the loom
to grip each edge of the fabric and are placed opposite each other; and it has been
stated that the fabric is gripped before the plunger arrives at the highest point of
said incline 9, and said grip is maintained on the fabric for an equal distance
each side of a line drawn through the center of the temple and through the bolt 2,
if the center of the slot in the tongue 12 coincides with the abovementioned
center-line. That is to say, said fabric is gripped at a point on one side of
said line equi-distant from said line with the point on the other side at which said
grip is released.
Thus, by moving said tongue 12 right or left, the point of gripping engagement
of said fabric may be varied relative to the point of release and thus more or less
transverse draft may be given to the temple as may be desired.
Figure 1 shows a thin rubber ring 24, similar to the ring 17, of the plate 17,
except that this ring is provided with short projections 24, which are adapted to
enter depressions in the tops of the plungers 15, when said ring 24 is placed on the
plunger-plate in a position opposite the ring 17 on plate 17.
The purpose of this ring 24 is to protect a very thin material from being injured
by the ends of the plungers being forced against it.

however light it may be, and one in which the adjustment for lateral draft on
said fabric is so simple and easy to operate as is the construction embodied in this

It is obvious that if desired more than one row of plungers 15 may be employed;
and that such construction would be clearly within the scope of this invention.
Such a construction might be desirable in temples designed to be used on looms
weaving exceptionally heavy fabrics.
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
1. A loom temple consisting of two revoluble plates supported face to face in
proximity to each other, a movable part in one of said plates, means for causing said
movable part to be moved across the space between. said plates and into contact
with the face of the opposite plate through the rotation of the plate in which said
part is supported, substantially as described.
2. A loom temple comprising two revoluble circular plates having substantially
coinciding axes, means of support for said plates, a movable part in one of said
plates, an undulatory surface on which said movable part is supported, whereby,
by the rotary movement of the circular plate bearing said movable part, the latter
is caused to move in a direction substantially at right angles to the plane of
rotation of said plate, and into contact with the other of said circular plates, and
means for varying the point of said contact, substantially as described.
3. A loom temple comprising two revoluble circular plates, supports for said
plates for permitting their rotation in proximity to one another in substantially
parallel planes, a plurality of parts supported in one of said plates for movement
therein in lines parallel with the axis of said plate, an undulatory surface on which
the parts in said plate bear, whereby when said parts are moved by the rotation of
said plates, they are successively moved towards the other of said circular plates,
at a predetermined point, and means for moving said undulatory surface whereby
said predetermined point may be shifted, substantially as described.
4. A loom temple comprising two circular plates revoluble in parallel planes,
one above the other, supports for said plates, a secies of concentrically arranged
plungers in one of said plates, a cam-plate located below said plungers and on
which the latter bear, whereby some of said plungers are supported in a plane
lying above that of the rest of said plungers, and in contact with the other of said
circular plates, whereby a piece of fabric may be gripped between said raised
plungers and said plate with which they are in contact, and means for moving said
cam-plate whereby the point of contact between said plungers and said
circular plate may be varied, substantially as described.
