9 Claims.

This invention relates to a loom and more especially to means for illuminating the reed in a loom and also the harness frames containing the heddles, when the loom stops.

It is a well known fact in weaving mills that, although there might be what is considered a good system of lighting, usually the source of illumination is so far away from the loom reeds and the lay cap in addition casts its shadow over the reed that it is difiicult to rethread the reed by passing open warp ends through the dents in the loom reed. In the weaving of very fine quality of cloth, the splits in the loom reed which form the dents or spaces therebetween are very fine and only a few thousandths of an inch thick, and the space between the splits which is called the dents is only a few thousandths of an inch wide. It is quite a strain upon the eyes and requires very good eyesight to pass the warp threads through the reed on account of a lack of sufiicient illumination. With my invention the reed is automatically illuminated when the loom stops also, if desired, the harness frames are automatically illuminated so that the heddle eyes also are plainly visible to an operator in passing broken warp ends through the heddle eyes and also through the loom reeds.

It is, therefore, an object of this invention to provide a source of illumination for illuminating the loom reed and also the harness frames, if desired, upon stoppage of the loom so that the warp threads can be easily rethreaded through the reed or through the heddles in the harness winds.

It is another object of this invention to pro- A vide a source of illumination for a loom reed and means automatically operable upon stoppage of the loom for energizing the source of illumination to illuminate the loom reed and also the harness frame adjacent to the reed.

Some of the objects of this invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings in which:

Figure 1 is an elevation of a portion of one end of the loom, showing parts in section and parts broken away;

Figure 2 is an elevation looking from the right hand side of Figure 1;

Figure 3 is an elevation of one side of the lay of the loom taken along the line 33 in Figure 1 with the center portion thereof broken away and showing my invention applied thereto;

Figure 4 is a transverse sectional view taken along the line 44 in Figure 3;

Figure 5 is a top plan view, with the shipper lever in section, of the guide for the shipper lever;

Figure 6 is a vertical sectional view taken along the line 65 in Figure 5;

Figure '7 is the wiring diagram of the illuminating means.

Referring more specifically to the drawings, the numeral It indicates one of the side frame members of a loom, said loom having a warp stop mechanism comprising a top conducting bar H and a bottom conducting bar l2 with a plurality of drop members l3 thereon through which the warp threads M of the warp passes. This warp stop motion has its upper bar ll grounded to the loom frame as at I6 and its bottom bar 12 is connected by a wire I! to a solenoid 58 which, when energized, raises a link !9 to raise a dagger Zllup to Where it will'be engaged by a bunter 2! disposed ona lay 22' of the loom.

The lay 22 of the loom is mounted on'suitable swords 23 which oscillate on a rocker shaft 25 mounted in the side frames of the loom. The dagger 2c is pivotally mounted on a lever 21 pivoted as at 28 and has a projection 29 adapted to engage the upper end of the shipper lever 30- to knock it out of the holding notch 31 to allow it to slide along a slot 32 in a bracket 33 to the dotted line position in Figure 5 when the bunter splits M therein forming dents between which the warp threads Id pass. These warp threads also pass through suitable heddles, not shown, in harness frames 13 and M, manipulated in a conventional manner by the loom mechanism. This mechanism thus far is conventional and it is in association with this mechanism that my tube 55 in any suitable manner such as by means circuit disposed in close proximity to the shipper f brackets 5| and 52. These brackets have lever, the shipper lever in operating position welded thereto suitable rods 53, 54 and 55 for holding the switch in open position, moving of protecting the tube against blows and for shadthe shipper lever by stop motion means to stop ing eyes of the operator in manipulating the loom 5 the loom serving to disengage the shipper lever and in rethreading the reed 46 at the harness from the switch to close the circuit to the source frames 43 and 44. One end of the tubes 59 and of illumination to thereby illuminate the loom 45are connected by a suitable wire 51. From the reed when the loom is stopped, and a second end of tube 45 therellealds a wire 60 through a source-qofiillumination mountecLon the lay and suitable connecter fil and :from theconnecter 6t '10 adapted to castii ts -rays of ilight ontolthe; harness I lead a wire 62 downwardly and properly supframes, said second source of illumination bein ported by one of the swords 23 to one side of a a connected in series in said circuit with the first coil 65 in a transformer 6-6.
