FOR WEAVERS' LOOMS." [A communication from abroad by La Société de
Tassigny Frères et Cie., of Reims, France.]
The teeth points or rollers with which loom temples have heretofore been
provided frequently tear fray or cut the fabric upon which they operate, but
according to the present Invention I obviate this defect by providing a temple in
which there are neither teeth nor rollers of the kind heretofore used.
The said Invention consists essentially in providing two cylindrical or conical
rollers over which the fabric or web pa-ses with an adherence which is regulated
by the pressure (variable at will) which is brought to bear upon the said rollers by
a third cylindrical or conical roller, the pre-sure being sufficient to hold or retain
the fabric and to cause it to be maintained in the loom, at its regular or proper
width. Two guiding rods which may be of half round or cylindrical or conical
shape lead or direct, the fabric to or from the aforesaid cylinders or cones as it
enters between and leaves the same. These gui les may be subjected to the same
pressure as the upper cylinder and impart it to the two lower cylinders in order to
increase the effect. The cylindrical or conical rollers of the temple may be made
of metal, wood, or composition. In order to ensure the necessary adherence of the
fabric upon the surface of the rollers the latter may be furnished with gold
beaters skin, buff, or other leather, hardened, vulcanized or ordinary india-rubber
or india-rubber mixed with pumice stone or other material, gutta percha, piste-
board, compressed paper, stucco, stone, or any other suitable material according to

page_text: r
the nature and strength of the fabrics. The cylinders or cones may be plain or
channelled or with helicoidal grooves according to the fabric which they are to
guide.
I will now proceed to describe, with reference to the accompanying Drawings,
the arrangement of the various parts of my improved temple and the method of
adapting the same to a loom it being understood that this method of adaptation
may be varied.
Figures 1, 2, 3, represent a top view or plan, a front elevation, and a side view,
of a temple constructed according to my Invention and mounted in the support by
means of which it is attached to the loom.
The remaining Figures are bereinafter referred to.
A is a guide serving to lead the fabric evenly or with regularity to the cone B.
C is a cone which also receives the fabric. D is a cone communicating pressure to
the two rollers B and C by means of the pressure screw J in order to cause the
fabric to be led evenly at its full width in the loom. E is a guide serving to hold
the fabric upon the cone C. F G H are the axes upon which the coues B C D are
mounted having nuts at their two ends and shoulders which fit to the bar or piece
which supports the said axes. I is the bar or piece to which the axes F G H are
attached this bar being partially to thed and provided with spring.
J is a
pressure screw for regulating the movement of the rollers B CD. K is a spring
permitting the temple to recede to avoid shocks. L is a guide which holds the bar I.
M is a worm for regulating the temple. N is the support of the temple which is
adapted to the loom. O is a support for the guide L and the worm M.
In Figures 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15 I have represented a
"modification of my said Invention which differs from the arrangement hereinbefore
described with respect to the manner of mounting the rollers and the guides on the
bar or piece, and with respect to a special arrangement of the rollers and guides
with the object of increasing the adherence of the fabric.
The support which carries the bar is the same as herein before described;
A represents a front view of the toothed bar or piece carrying the guide rods and
the rollers. A is a side view of the same. B is a front view of the said bar
with the guides but without the rollers. B' is a side view of the same. C C' are
bearing pieces for holding the rollers. D Dare screws which guide the bearing
pieces CC for producing more or less pressure upon the trunnions of the rollers.
E is a guide for leading the fabric evenly to the roller F. The position of this
guide may be varied by means of a slide and screw. E is a second guide for
holding the fabric upon the roller G. These two guides may be replaced by small
rollers either of cylindrical or conical form made of metal or clothed in the same
manner as the rollers F G H. They may be smooth or provided with helicoidal
grooves. F is a roller for receiving the fabric, G is a similar roller for the same
purpose. His a roller for exerting pressure upon the two rollers F G by means of
the pressure screws D D¹. I represents conical portions of the rollers F G H and
of the guides (see Figure 15) upon which a part of the border is reversed thus
increasing and completing the drawing or stretching effect. J is a small plate,
which, by means of a screw, holds the bearing piece C'. KKK represent cylinders
with plain surfaces and of different dimensions.
The manner of mounting the rollers upon the bar and the arrangement of the
same render the temple made according to this modification stronger and more
effective.
In Figure 14 I have represented a method of mounting cylindrical guides E El
which permits the latter to bear upon the rollers F G with a pressure regulated by
the screw D. These guides thus assist, with respect to pressure, the cylinder H.
These guides may also have a conical end I see Figure 15 like that of the compressing
cylinder H so that the conical parts I of the cylinders F and G may be pressed by
the conical parts I of the guides E as they are by the cone I of the cylinder H for
the purpose set forth.

the fabrics. These cylinders or cones may be plain or channelled or may have
helicoidal grooves according to the fabric which they are to guide.
I will now proceed to describe with reference to the accompanying Drawings the
arrangement of the various parts of my improved temple and the method of adapting
the same to a loom it being understood that this method of adaptation may be
varied.
Figures 12 and 3 represent respectively a top view or plan, a front elevation,
and a side view of a temple constructed according to the said Invention and mounted
in the support by means of which it is attached to the loom.
The remaining Figures are hereinafter referred to.
A is a guide serving to lead the fabric evenly or with regularity to the cone B.
C is a cone which also receives the fabric. D is a cone communicating pressure to
the two rollers B and C by means of the pressure screw J in order to cause the
fabric to be led evenly at its full width in the loom. E is a guide serving to hold
the fabric upon the cone C. F G H are the axes upon which the cones B, C, D,

are attached this bar being partially toothed and provided with a spring. J is a
pressure screw for regulating the operation of the rollers B C D.
K is a spring
permitting the temple to recede to avoid shocks. L is a guide which holds the
M is a worm for regulating the temple. N is the support of the temple
which is adapted to the loom. O is a support for the guide Land the worm M.
In Figures 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15, is represented a modification
of the said Invention which differs from the arrangement bereinbefore described
bar I.

page_text: with respect to the manner of mounting the rollers and the guides on the bar or
piece and with respect to a special arrangement of the rollers and guides with the
object of increasing the adherence of the fabric.
The support which carries the bar is the same as hereinbefore described.
A represents a front view of the toothed bar or piece carrying the guide rods and
the rollers. A is a side view of the same. B is a front view of the said bar with
the guides but without the rollers. B₁ is a side view of the same. CC are
movable bearing pieces for holding the rollers. D D¹ are screws which guide the
bearing pieces CC for producing more or less pressure upon the trunnions of the
rollers. E is a guide for leading the fabric evenly to the roller F. The position
of this guide may be varied by means of a slide and screw. E is a second guide
for holding the fabric upon the roller G. These two guides may be replaced by
small rollers either of cylindrical or conical form made of metal or clothed in the
same manner as the rollers F G H. They may be smooth or formed with
helicoidal grooves. F is a roller for receiving the fabric, G is a similar roller for
the same purpose. H is a roller for exerting pressure upon the two rollers F G by
means of the pressure screws D D'. I I represent conical portions of the rollers
F G H and of the guides (see Figure 15) upon which a part of the edge or border
is reversed thus increasing and completing the drawing or stretching effect. J is
a small plate, which by means of a screw, holds the bearing piece C¹. K K K
represent cylinders with plain surfaces and of different dimensions.
The manner of mounting the rollers upon the bar and the arrangement of the
same render the temple made according to this modification stronger and more
effective.
In Figure 14 is represented a method of mounting the cylindrical guides E E¹,
which permits the laiter to bear upon the rollers F G with a pressure regulated by
the screw D. These guides thus assist, with respect to pressure, the cylinder H.
These guides may also have a conical end I (see Figure 15) like that of the
campressing cylinder H so that the conical parts I of the cylinders F, G, may be
pressed by the conical parts I of the guides E as they are by the cone I of the
cylinder H for the purpose set forth.
If the fabric has very little elasticity, the guides E E¹ in order that they may
offer little resistance to the operation of the loom should be of cylindrical or conical
form either with a smooth surface or having grooves either straight or spiral.
These guides may be either fixed or movable in the direction of their axes, and in
the latter case they may be moved by means of a slide and screw.
Pressure may
also be exerted upon the cylinders F G by any suitable means. The ends of the
guides may be in the form of a truncated cone, corresponding to that at I in the
compressing cylinder H so that the conical part I of the cylinders F G are pressed
by the corresponding conical parts of the guides E E. To still further facilitate
the operation of the apparatus, all the cylinders may be mounted on pivots. The
cylinders instead of being grooved may have raised pieces on their peripheries.
Any suitable number of upper and lower cylinders and of guides may be
employed, and may be made of any suitable material having notches or roughened
surfaces of any kind sufficiently smooth not to cut or pierce the fabric. These
roughened parts may be arranged spirally in order to more effectually maintain the
fabric at its full width.
In Figures 16 to 28 are represented various modifications of the said Invention.
The bearings and the screws designed to exert a pressure upon them are dispensed
with. The piece A adjusted by means of a screw and thumb-nut J is employed in
place of the screws hereinbefore described, and the feet B of this piece A serve as
bearings (Figure 16) or guides G may be used instead of the feet B; these guides
may be made larger if desired, and may impart the same pressure to the guide
bars F (Figures 25 and 26).
In order to equalize the pressure on the compression rollers D, a spring may be
placed between the piece A and the top of the temple, or preferably a spring
placed between the piece A and the thumb-screw J (Figure 18). This combination

page_text: will permit the compressing cylinders to rise slightly when there happens to be
a knot or thick part in the fabric; the same result may be obtained by making the
piece A of steel and a little curved so that it will press upon the compressing
cylinders D. Cylinders K of various forms may be employed if desired.
In Figures 29 and 30 is shewn a device for giving better effect to the operation
of the improved temple. The fabric is passed through as shewn in Figure 30, that
is to say, below the cylinder A and above the cylinders D D' and the spirals of the
cylinders are placed in such a manner that they will draw in the same direction.
With some very strong fabrics the draught may be augmented by adding two
compressing cylinders E of small diameter acting upon the upper part of the
roller B on each side. Or, as shewn in Figure 29 the fabric may be passed under
the guide cylinder D then over the cylinder A under the cylinder B, over the
cylinder C and under the guide cylinder D', the spirals, as in the preceding case,
being arranged in the proper direction.
If it is desired to use compressing cylinders E they are made to act upon the
cylinders A C. I do not limit myself to the number of rollers, compressing
cylinders and guides, which may be varied as required.
Having thus fully described the said Invention as communicated to me by my
foreign currespondents, and the manner of performing the same I wish it understood
that I claim―
First. The improved temple for drawing the fabric in the direction of the weft,
and consisting essentially of a suitable number of rollers, either cylindrical or
conical, pressed upon by one or more adjustable rollers, in combination with the
guides or guiding rods which lead or direct the fabric to and from the said rollers,
substantially as set forth, and as shewn in the accompanying Drawings.
Second. The arrangement of the support for attaching the temple to the
frane of the loom, substantially as set forth, and as shewn in the accompanying
Drawings.
In witness whereof I the said William Robert Lake have hereunto set my
hand and seal this Eighteenth day of July in the year of our Lord One
thousand eight hundred and eighty two.
