LOOM TEMPLE
Robert Stevenson, Providence, R. I., assignor to
Mechanical Holding Corporation, a corporation
of Rhode Island
Application September 27, 1935, Serial No. 42,473
6 Claims.
(Cl. 139-295)
This invention relates to a loom temple for
holding woven fabric taut in a widthwise direc
tion in a loom, and has for one of its objects
the provision of a loom temple which will be
adapted for use with fabrics of varying thick
nesses without manual adjustment.
Another object of the invention is the provi
sion of a construction of loom temple which will
operate upon fabrics of Varying thicknesses with
1 O substantially the same amount of frictional en
gagement regardless of the thickness of the cloth.
Another object of the invention is the elimina
tion of markings on lightweight, fragile goods
such as silk or rayon by the use of toothed rolls
15 as occurs in the old style temple.
Another object of the invention is the provi
sion of a loom temple the parts of which will need
to be replaced less frequently than temples which
2O
have heretofore been in commercial use.
With these and other objects in view, the in
vention consists of certain novel features of con
struction, as will be more fully described, and
particularly pointed out in the appended claims.
In the accompanying drawing:
Fig. 1 is a perspective view of the loom temple
and its mounting structure;
Fig. 2 is a top plan view of the device with the
cap and movable carriage removed and showing
the base with spaced rolls mounted therein;
30
Fig. 3 is a perspective view of the movable
25
carriage;
Fig. 4 is a plan view of the underside of this
carriage;
Fig. 5 is a perspective view of the cap or guide
3
member;
Fig. 6 is a perspective view of the resilient
member or spring;
Fig. '7 is a sectional view through the central
40
portion of the device; and
Fig. 8 is a sectional view on line 8-8 of Fig
ure 7.
In the use of loom temples it is usually re
quired that adjustments be made when varying
thicknesses of fabrics are woven in the loom. In
45 the Gilpin Patent No. 1,934,495, dated Nov. '7,
1933, with which I am familiar, an attempt has
been made to provide an easy adjustment of a
bar in the temple, but no adjustment occurs
automatically nor is there any adjustment of the
50 fabric engaging guiding edges, so that different
surface frictions occur depending upon the
thickness of the cloth woven in the loom; and
in order to provide a device in which there will
5
be substantially the same sinuous path provided
through the temple and one in which the adjust
ments need not be made mechanically. I have
provided a carriage for mounting a roll above
the spaced base rolls so that the entire carriage
with the roll is movable up and down and spring
60 pressed toward the base, the edge of the carriage
serving as the guides for the fabric to determine
its path of travel over the base rolls; and the fol
lowing is a more detailed description of the
present embodiment of this invention, illustrat
ing the preferred means by which these advan
tageous results may be accomplished:
With reference to the drawing, I0 designates
-the base of the loom temple which is provided
With spaced bearings II and I2 at one end and
I3 and I4 at the other end for rotatably mount
ing in spaced relation the axles of the rolls I5
and I6. This base is provided with a suitable
arm I'I having a lip I9 with holes 20. A bracket
I8 adjustably receives the arm I1 for supporting
the same in position on the loo-m. One end of
the base is provided with a groove 22 which re
ceives the tongue 23 of the cap and guide mem
ber 24 which has overhanging arms 25 of gen
erally L-shaped cross-section with an elongated o
opening 25 between them and, as shown in Fig.
5, is of generally rectangular form with a bridge
piece 2'! connecting the arms 25 at their outer
ends, said arms and bridge piece overhanging the
base and being spaced therefrom.
‘
A carriage 30 is mounted for vertical move 25
ment in the opening or space 26 between the
arms 25, this carriage being provided with guide
surfaces 3| to engage the inner surfaces 32 of
the arms 25 on either side thereof, and a guide
surface 33 on the upstanding portion 34 toy en 30
gage the inner surface 35 of the bridge piece 21
at one end and a guide surface 36 at the other
end to engage the inner surface 3l between the
arms 25 at the other end. Thus, this carriage is
guided and may move vertically between the in 35
ner edges 32 of the arms 25 and the inner surface
35 of the bar 27 and the inner surface 31 of the
body portion of this cap». The lower portion of
the carriage below the surfaces 3| broadens to
provide abutment surfaces 38 located beneath 40
the arms 25, while the edges of the lower surface
of the carriage are provided with lips 39 which
are rounded to provide guide surfaces for the
cloth 40 in passing from between the rolls. Resil
ient means such as a leaf spring 4I are located 45
beneath each of the arms 25 to engage the sur
faces 38 of the carriage to tend to force it down
wardly. A groove 42 is provided on the under
side of this carriage in which there is mounted
a roll 43 in bearings 44 at either end thereof to '
be moved with the carriage toward the rolls on
the base.
In operation, the woven fabric passes over the
spaced rolls I5 and I6 and beneath the edges 39
and the upper roll 43, as shown in Figure 7. 'I‘he
thicker the fabric the more the carriage will be
forced up against the tension of the springs 4I,
while the fabric will maintain substantially the
same sinuous path and the same extent of fric
tional contact with the rolls regardless of its 60

thickness. Further, by reasonof this loom tem
`extending longitudinally thereof to form spaced
ple no mechanical adjustments such as shimming
up the cap or attempting to adjust screws or bolts
or the like is necessary each time a different
thickness fabric is operated on by the loom.
ported for vertical movement above said base,
The foregoing description is directed solely to
wards the construction illustrated, but I desire it
to be understood that I reserve the privilege of
resorting to all the mechanical changes to which
_ the device is susceptible, the invention> being de
fined and limited only by the terms of the
appended claims.
