WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN AND RELATING TO TEMPLES
FOR WEAVERS' LOOMS." [A communication from La Société de Tassigny frères
et Cie., of Reims, France.]
The teeth points or rollers with which loom temples have heretofore becn
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 passes 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 pressure 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 guides 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, paste-
board, compressed paper, stucco-stone, or any other suitable material according to
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 templo and the method of
adapting the same to a loom, it being understood that this method of adaptation
may be varied.

page_text: 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 on 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 or cones 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, D, C, 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 toothed and provided with a
spring; J is a pressure scrow for regulating the movement 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 bar I. M is a worin or screw 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 or screw 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, D³, are screws which guide the bearing
pieces C, C¹, for producing more or less pressure upon the trunnions of the
rollers; E is a guide for lending 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 or
covered in the same manner as the rollers F, G, H. They may be smooth or
provided with belicoidal 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, 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 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 I have represented a method of mounting cylindrical guides
E, E¹, which permits the latter to bear upon the rollers F, G, with a pressure
regulated by the screws 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, E', as they are by the cone I
of the cylinder H, for the purpose set forth.
