(oi. 13942 55 the reed side, of providing the necessary rigidity in theypartsywith which the fabric contacts i passing,toresist the efforts to which they are subg mitted, and of ensuring ';that .-thegfabric ;has;, a sufliciently large enveloping arc aroundtlie lower p r 'of th 'cyli d r-pr .i. 1.

The fact that this temple offers only a small bulk in height, on the; reed side, enables. it to be used, in'particular, with looms on the sleyof which are fixed elements for the guiding;of the Weft carrier or needle as well ascertain parts which, at the forwardbeating-ue movement of the batten, must be able to pass freely under the t mp f1 According to the invention, the temple is char acterized in that it comprises; a plate l aving -an opening arranged longitudinally below the cylintier and xt d-ins p f ably. be o th 13 of said cylinder to assist in l hfijensioning of the selvedge of the fabric downwardly deflected under the cylindensaid opening in the plate providing. a'bar' of reduced height and Width on the side facing the reed; a relativelywlde table suitably profiled longitudinally and transversely on the *side opposite to the'reed side; and a foretable at the end: 1 E

Other characteristics and advantages will appear in the following description of a construction or arrangement of a t mple designed according 'to'the invention that is givenmerelyby way of non-limitative'example, reference being made to the attached drawing, in which:

Fig. 1 is a side elevation of a temple intended for the right-hand selvedge of the fabric and supposed to be seen from the front of the loom;

Fig. 2 is an end elevation of Fig. 1;

' Fig. 3 is a cross-sectional elevation taken on the line III-III of Fig. 1;

Fig. 4 is a plan View of Fig. 1;

Fig. 5 is an end elevation showing a variant of the profile of the fore-table.

I is the ring cylinder of which 2 are the rings fitted with spikes 3; 4 is the centre spindle of the spiked ring cylinder fixed in a support 5 which has, for this purpose, a slide I5 to enable the height to be adjusted.

Risa plate integral with thesupport -5 a nd at right angles thereto, having an elongated opening-1 extending under the cylinder:- in the same direction and beyond the free end-of- -the latter. This opening is bordered, on theside facing the reed, by a part of reduced height and ,width, in the form'of a small bar 6a; onthe breast beam side, by a part 6b of relatively considerable width formlng'a table; and; at the; end by a fore-table 6c. The fabric, fromith e fellof the cloth onwards, passes] over the-bar tainto the opening 1, under the cylinder l encirclin g partly its lower part and then passes on to-the table 612-. The end of the plate 6 directed towards thecentre of 2 the fabric and forming the foreetable 5c, fx; tends sufficiently beyond the opening 1 tinni-v part, amongstother advantages, the necessary rigidity to the bar to. I r The bar to is preferably trapezoidal in c oss section. The faceoppositethe reed 8' advantageously is sloped or inclinedto correspond with the greatest obliquity that the reedcan assume, at the moment of the beating up of-the weft, and the face turnedtowards the cylinder I isarranged at a short distance fronithe latter-.---;A's a result of its shape, the bar Boa-extends a' little beyondthe cylinder I, so that the distance ;'be tween the reed iiv when in beating .up position (Fig? 3) and. the-place where the fabric comes into contact wanes: spikes 3 on the rings 2 --is reduced to ,theii'iinimuin. Further "the bar ta, the rigidity Of which is ensured .by its construde 'tion, can, despite its" narrowness, be of su'cha low.

The table 6b can be shaped over all .or part of its-length, with apro'gressive increasein thick ness that can extendto the support 5, The table :51; may alsoi befp-rovided .with a longitudinal profile" consisting of wavy line having arising part followed by a horizontal part and, then. eventually, by a falling part, or still, by a rising curve or a rising and a falling one, or again, as shown in the drawing, by a rising straight part followed by a curve that rises and then falls.

Crosswise ridges 9, preferably in the shape of the teeth of a saw, may be arranged on the whole or part of the surface of the table 6b, which, combined with the rising cross profile of the table 6b, contribute to maintain the width of the fabric and thus assist the action of the cylinder on the latter.

It is possible with advantage to render the upper part of the table 6b interchangeable by providing it with a removable plate 6d fitted on its lower face with studs l9 fitting into holes H. Thus it is easily possible to alter the profiles lengthwise and crosswise and the nature of the surface of the table by the changing of the plate so as to adapt the action of the temple to the type of fabric and to the working conditions oi the loom.

The upper part of the longitudinal edge of the opening I, that comprises the table 612 or/and the plate 6d, includes a rounded part 1a., preferably progressive with the slope, to facilitate the travel of the fabric.

The fore-table 60 may increase in thickness from the bar 6a. This fore-table 60 also can he advantageously provided with ridges arranged. in a general direction similar to that of the ridges 9, when its profile swells out as shown in Fig. '5. s The part of the bar 6a adjacent to the support 5 can havea beak or projection I2 arranged above it, the purpose of this projection being to guide the weft threads or/and the warp threads.

Further, a finger [3 may be provided, at a suitable distance from the cylinder, for the purpose of guiding the selvedge.

The cylinder is provided with a sleeve I l between the support 5 and the first spiked ring 2, the sleeve being of such a length that the first ring will act in the best conditions.

Itis to be understood that variants, improvements of detail and uses of equivalent means may be conceived and employed without departing from the scope of the invention. Thus for instance the plate 6 may be prolonged in such a way as to be mounted on the breast beam or on the 'scrimp bar, in which case the size of the support 5 in which the centre spindle 4 is mounted is reduced.

The slide [5 provided-in the support 5 for the mounting of the centre spindle 4 of the cylinder I need not be vertical, but may be inclined in order to favour the action of the cylinder when the reed is inclined.

What I claim is:

1. A temple for weaving looms of the trough and roller type, adaptedto tension the fabric downwardly deflected, comprising an elongated plate; a support projecting at one end of said plate; a cylinder rotatably mounted in said support; said plate having a longitudinal aperture under the cylinder and extending therebeyond for 'forminga fore table and a table portion, said table portion on one side, having a surface the said plate on'the opposite'side thereof.

2. A temple according to claim 1, wherein the table portion has a thickness progressively increasing in the longitudinal direction on at least a part of its length from the end opposite the support towards said support.

3. A temple according to claim 1, wherein the table portion has a thickness progressively varying in the longitudinal direction on at least a part of its length.

4. A temple according to claim 1, wherein the table portion has a thickness varying in the longitudinal direction on at least a part of its length to form a rising straight part followed by a curve that rises and then falls.

5. A temple according to claim 1, wherein the table portion has a thickness varying in the longitudinal direction on at least a part of its length, to form a slope up and a consecutive slope down.

6. A temple for-weaving looms of the trough I and roller type, having a reed and adapted to tension the fabric downwardly deflected, comprising an elongated plate; a support projecting at one end of said plate; a cylinder rotatably mounted in said support; said plate having a longitudinal aperture under the cylinder and extending therebeyond for forming a fore table and a table portion, said fore table, on the side opposite the reed side, having a thickness progressively increasing in the longitudinal direction on at least a part of its length from the edge towards said table portion, said table portion, on the side opposite the reed side, having a surface the shape of which in longitudinal and transverse direction is adapted to receive said fabric; and a substantially low and narrow bar integral with said plate on the reed side thereof.

' '7. A temple according to claim 1 wherein at least a part of the table portion is transversely serrated.

8. A temple according to claim 1 wherein at least a part of the table portion is transversely serrated.

9. A temple according to claim 1 wherein at least a part of the table portion is madeof a removable piece.

10. A temple according to claim 1 wherein the bar is provided with a guiding projection adjacent to the support.
