Patented Dec. 13, 1949 UNITED STATES PATENT OFFICE 2,491,092 DROP WIRE COVER A ND WARP BRUSH John S. Denney, Lat Grange, Ga. Application December 17, 1948, Serial No. 65,892

This invention is particularly concerned with the preventing of trash of all kinds from falling on the drop wires or detectors forming part of a warp stop motion equipment of a loom. As is well-known in the art when lint or other trash on the warp is permitted to come into contact with the drop wires or detectors draw-backs, breakouts and other objectionable defects de- 6 Claims. (Cl. 139349) through the medium of hinges tending walls 9, l0, respectively, hinged as at H and P2 to a stationary wall section l3 that extends Briefly, the present invention consists in the provision of a combined drop wire or detector finger cover and warp brush for attachment to the loom to substantially enclose the drop wires and to wipe the warp clean to thereby preclude the possibility of lint and other trash on the warp passing therewith into contact with the drop wires or detector fingers.

The invention together with its objects and ad-' vantages will be best understood when the following detailed description is read with reference to the accompanying drawing in which is illustrated what is presently considered a preferred embodiment of the invention, and wherein:-

Figure 1 is a fragmentary perspective view of a loom illustrating a practical application of this invention;

Figure 2 is a perspective view of the combined drop wire cover and warp brush emboding the features of this invention;

Figure 3 is a front elevational view of the combined drop wire cover and warp brush, with a frame part of a loom shown in cross section, and illustrating the manner in which the device of this invention is mounted on the loom and the movability of parts of the device with respect to the loom; and

Figure 4 is an end elevational view of the drop wire cover and warp brush with the longitudinal wall sections thereof shown in a partially raised position.

Referring now in detail to the drawing it will be seen that the combination drop wire cover and warp brush of this invention is in the form of an attachment to be applied to a loom without altering the structural details of the latter. To that end the device comprises a pair of attaching plates 5-5, a hood having end walls 6 that are detachably connected to the members between the end walls 6 and is secured at its opposite ends to the walls 6 at the upper edges of the latter as at M.

The aforementioned hood comprising the walls 6, 9, Ill and I3 may be of any suitable cross sectional shape, the only requirement as to the cross sectional shape and longitudinal, dimensions of the hood being that they be sufficient for the.

hood to extend over and substantially enclose the drop wires l5 of the loom it (see Figure 1) to which the hood is applied as contemplated by this invention.

The wall 9 of the hood is provided at its free longitudinal edge with a flange I! to which is.

While the brush secured as at I8 a brush 19. may be of any suitable construction, it preferably embodies a back or base portion formed from a or trash that might fall on the warp.

It is also within the contemplation of this in- I vention to provide the wall ID at its free longi- It may be also here stated that when desired a suitable} brush may be suspended in any well-known mantudinal edge with a rolled edge 20.

ner from the edge 20 of wall It for brushing loose ends of the threads from the warp so that the loose ends will be free to fall to the floor free of the loom.

There are also suitably mounted on the wall section [3 of the hood rings or eyelets 2! which may be selectively engaged with any suitable suspension means (not shown) mounted on the loom l6 above the drop wires [5 for holding the hood in, for example, the partially raised position shown in Figure 3 to permit access to the drop wires [5, as might on occasion be required.

In applying the device of this invention to the loom l6, and as shown to advantage in Figures 1 and 3, the attaching plates 5 are secured to opposite portions of the frame IEO. of the loom l6 at the desired position of vertical adjustment through the medium of tap bolts 22 that are threaded into the frame Ito and extend through slots 23 provided in the attaching plates 5. The plates 5 thus serve to support the hood of the del equipped with removable hinge pins 8, and longitudinally exvice transversely on the loom and over the drop wires l which form, as is well-known in the art, part of a thread detecting mechanism or electric warp stop motion now generally constituting standard loom equipment, and the brush IS in wiping engagement with the warp 24.

In actual practice with the hood and brush of this invention in proper position on the loom and as shown in Figure 1, the hood will effectively serve to substantially enclose the drop wires !5 to prevent lint, cotton, and other trash from falling on the drop wires, while at the same time the brush, being in wiping engagement with the warp 24, will serve to effectively pick up all loose ends of the warp and cotton and trash that would otherwise fall on the warp and, in the absence of this invention, be carried with the warp into the drop wires, or as they are sometimes referred to in the art, detectors l5.

It is well-known in the textile industry that lint, cotton and other trash which is permitted to contactthe drop wires or detector fingers 15 of a loom cause what are known in the art as mat-ups,v

draw-backs, breakouts and other defects in the finished cloth With my invention the causes of these defects in the cloth are prevented by reason of the fact that through the medium of the hood and brush assembly contemplated by this inventionand' operating in the manner herein described trash of all kinds is precluded from fallin on the drop fingers or detectors [5 of the cm. As a result a loom'equipped'witha drop wire cover and a. warp brush assembly as herein described will produce a high quality of cloth and at minimum cost,,tl1eproduction capacity of the loom. being materially enhanced as will be apparent to those skilled in this art.

It will also be appreciated from the detailed description oi this invention that either of the walls 9 and "I may be swung upwardly on the hinges" H and l2'soas to permit ready access to the drop wires !5 from either side of the hood; and thatalso' by removing the hinge pin 8 of a selected hinge T the hood may be vertically swung upwardly on the other'hinge i as suggested in Figure 3 seas to expose the entire assembly of drop Wires l5 and thereby permit complete access tc-the wires:

Also by vertically adjusting the plates 5 on the. frame Him the hood and associated brush ['9 are supported at the desired position of elevated ad.- J'ustment with respect to the drop wires and warp 24 as desired and as conditions of use may dictate.

While the invention has been described in detail in its presently preferred embodiment, it will, of course, be understood that such has been done for purposes of illustration only and not by way of limitation, and therefore only such limitations are to be imposed thereon as may reasonably come within the scope of the appended claims.

What I claim is:

1.. A combination dropwire cover and warp brush for looms, comprising a casing adapted to be mounted on the loom to substantially enclose the drop wires, and a brush disposed on the casing for wiping. engagement with the warp.

2. A loom attachment comprising a casing for disposition over the drop wires of the loom, and a brush mounted on the casing and extending lengthwise thereof for brushing contact with the warp andzco-acting with the casing to prevent lint and other trash from falling on the drop wires 3..A loom comprising. in combination, drop wires,.

a casing substantially enclosing said. drop wires,

and a brush mounted on the said casin in brushing. contact. with the warp.

4. A loom comprising in combination, drop wires, a casing disposed over said drop wires,v

a brush mounted on the casing in wiping contact with the warp, and interengaging means on the loomand on the casing for supporting the latter andbrush atv selected positions of vertical adiustmerit onthe loom.

5. A casing. for disposition over the drop wires of a loom comprising attaching members, a hood.

having end. walls hinged to the attaching members, and longitudinal wall. sections hingedly supported between the end walls.

6..A.casing for disposition over the drop. wires of. a loom comprising attaching members, a hood having end walls hinged to the attaching. members,.and longitudinal wall sections hingedly supported between the end walls, and a brush.
