This invention relates to a loom selvage apparatus which is capable of reinforcing the selvage ends of the warp while the filling is being projected through the shed so as to construct a cloth having the same appearance throughout. In many types of cloth it is very desirable to have the selvage warp ends of the same density as the ends throughout the intermediate portion of the cloth. This is particularly desirable where the cloth or fabric is to be subsequently coated as in the case of rubberized goods. In conventional weaving suitable right and left hand temples are used for the purpose of engaging the selvages of the cloth while the filling is placed therein. vIt is also customary to place the selvage ends closer together than the intermediate ends in order to provide a stronger area near the edge of the cloth to counteract the force applied thereto by the weft end.

It is an object of this invention to provide a loom selvage device which may be employed on either the right or left hand temples for reinforcing the selvage warp ends while the filling is being placed therebetween. By providing this reinforcing device, it is not necessary to make the warp ends near the selvage of any greater density than at the other points; consequently, the fabric, after it has been woven, will havethe same appearance at the edge as it has in the It is a further object of this invention to provide an apparatus for holding the selvage thread in a loom during the pick, comprising a temple head having a shank projecting downwardly therefrom and engageable by the lay of the loom upon the beat up stroke, a comb member pivoted on the said shank and having a cam sur face, adjacent its pivot point projecting into the path of the lay and spring pressed means for normally forcing said comb into engagement with the selvage warp ends thereby the selvage warp ends will be reinforced while the shuttle is insertingthe filling within the Warp shed and whereby the comb will be removed from the selvage upon the beat up stroke of the lay.

By the use of this apparatus, double width cloth can be woven in a loom without, leaving any tell-tale markings in the center of the double width cloth after the cloth hasundergone a finishing operation.

Some of the objects of the invention having been stated other objects will appear as the description proceeds when taken in connection with the accompanying drawing, in which' Figure 1 is a transverse sectional view through a portion of a loom showing the improved device mounted on a loom temple;

Figure 2 is a plan View taken. along the line 2-2 in Figure 1;

Figure 3 is an isometric view of the improved loom selvage device;

Figure 4 is a vertical sectional view taken along the line 4-4 in Figure 1.

Referring more specifically to the drawing, the numeral ll] denotes the stationary or slide portion of the loom. temple which has slidably mounted therein, shank II. This shank has integral therewith a temple head l2,. said temple head having rotatably mounted therein, a gripping roller. M as at l5. This gripping roller is adapted to engage the selvage of the. cloth immediately after it is being woven. The cloth is formed in the conventional manner by a pluralityof warp ends l6 and a filling thread I! which thread is carried back and forth through the shed in a conventional manner.

A lay I 8 is also provided which has a reed l-9 mounted therein between, which the warp ends 16 are adapted to pass. InFigure 1 the-bold line position of the lay indicates the position which is occupied when the shuttle passes through the warp thread. The dotted line position indicates that position that the lay occupies upon the beat up stroke atv the time the shuttles are disposed in the shuttle boxes at opposed ends of the lay.

As heretofore stated, it is desirable in many instances to produce a fabric which is uniform throughout and in order to do so it is. necessary to reinforce the selvage ends l6 so that the tension of the filling thread I! will not have a tendency to narrow the cloth or to produce an excess strain upon the selvage ends. In order to do this, a suitable comb 22 hasbeen provided, said comb having a plurality of teeth 23 extending downwardly therefrom. This comb is insertable within U-shaped member 24 and after it has been inserted a bolt 25 is tightened to lock the comb in position. The U-shaped member 24 is integral with a laterally projecting arm 25, said arm having slots 25 therein which slots are penetrated by screws 21. These screws have their other ends threadably embedded in an arm or bracket 28, and this arm projects forwardly and then downwardly (Figures 1 and 2) and has a suitable hole 29 therein which is loosely penetrated by a bolt 30.

The bolt 36 is fixedly secured to a suitable lug 3|. on downwardly extending lip or flange 32 of the temple head. Although the bolt 30 is fixedly secured in this lug, the arm 28 is nevertheless mounted for oscillation therearound and a suitable spring 35 is provided for normally forcing the comb 23 into bold line position as sh wn in Figure 1 so that the selvage warp ends will be reinforced while the shuttle passes through the warp shed. Torsion spring 35 has one end thereof penetrating the head of bolt 30 as at 31 and its other end engaging the front of arm 29 as at 38.

Also it will be noted that the lower end of arm '28 has integral therewith a cam surface or pro- :jection 40 which normally extends upwardly into the path of the lay [8. Upon the beat up stroke of the lay, that is when the lay assumes the dotted line position as shown in Figure 1 the rear edge of this projection 40 is engaged which will rotate the comb 23 to dotted line position and thereby allow the filling end to be beat up to its proper position to cause cloth to be formed. As the lay moves toward bold line position then the torsion spring 35 will force the comb 23 to an engaged position with the selvage to act as a reinforcing member.

It has been found necessary to cut the temple head [2 as at In to allow the proper clearance of the teeth of the comb when the lay beats up. It also allows the assembly to be more compact.

The purpose of providing the slots 26 and the screws 21 is to allow the necessary adiustment of the position of the teeth of the comb 22.

In order to furnish a suitable limit or stop against which the arm 28 may rest, while the lay is in heat up position, a fibrous or lint block 42 is secured to the side of member H by any suitable means such as screws 43. This stop does not interfere with the operation of the arm, but merely prevents the arm from being rotated too far in a clockwise manner should. the beat-up stroke of the lay furnish an excessive impact to the comb supporting arm 28.

It is, therefore, seen that we have provided a simple loom selvage apparatus which is operable upon each beat up stroke of the lay and which will reinforce the selvage ends of the cloth in such a manner that it will not be necessary to make the selvage warp ends more numerous than at other points.

In the drawing and specification there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only. and not for purposes of limitation the scope of the invention being set forth in the appended claims.
