March 24, 1931. c, GlLMORE LOOM ATTACHMENT- Filed May 16, 1929 2 Sheets-Sheet 1 III! gwvwntoo MOR Patented Mar. 24, 1931 UNITED STATES PATENT OFFICE 7 WILLIAM C. GILMORE, OF GREENVILLE, SOUTH CAROLINA 1.00 ATTACHMENT- Application filed m 16, 1929. Serial No; 363,569.
My invention relates to attachments for looms and more particularly to a device which is primarily intended to be applied to the loom temples for the purpose of catching the loops of the filling yarn which are not woven intothe selvage,although of course the device is adapted to engage a selvage loop itselfand hold thesame until the weft threads forming said loop have been beaten up in the 7 fabric by the reeds intheforward movement of the lay. V V
Ordinarily, in some classes of goods Woven on looms, owing to the tension of the yarn,
a catch cord' (sometimes called a selvage cord) has to be used to hold the looped ends of. the
filling yarn. The shuttle laying the filling yarn first passes over the cord and in its return movement passes under the cord. It
frequently occurs that the catch cord becomes broken with the result that the selvage is imperfect and the goods damaged.
Briefly stated, this invention has for its primary object to eliminate the necessity for also adapted to engage a free loop of filling yarn, or a selvage loop until the same is beaten into the fabric thereby preventing the formation of saw teeth or filling cuts in the selvage,thenature of the device being such that it can be readily applied to standard loom temples, and being susceptible of adjustment as the occasion may require to the end that the most efiicient operationmay, be obtained.
A further object of the invention resides in the provision of a novel guide means for the loop-engaging elementf-which guide means positively effects a stripping of the loop from the loop-engaging element when the same is retracted in the'movementof the i lay towards the breast beam of the loom.
A further object of the invention resides in the provision of a device ofthiskind.
adapted to be operated by the lay of the loom which, incorporates novel catching means, whereby the loop-engaging element can be maintained in inoperative position.
7 The invention also resides in certain novel 50. features of construction, comblnatlon and arhave been illustrated as are consideredneces- '-sary for an understanding ofthe invention the use of the catch cord for holding the looped ends of the filling yarn, and which is rangement of the various parts and in modes of operation,' all of which willbe readily understood and appreciated by those skilled in the art, upon reference to the accompanymg drawlngs 1n con unction with the followin hand; j
2 is a side'elevational view of a loom te'm'ple'to which my invention is shown applied,'there being illustrated also aportion of the lay of the loom;
Fig. 3 is across-sectional view thru the temple taken'on the line 33 of Fig; 1;
Fig. 4: is a view similar to Fig. 2 but showing the loop-engaging element retracted thru the instrumentality of the lay-in its forward movement;
Fig. 5- is a diagrammatic view, partly in i section and'illustr'ating'the. operative action.
of the loop-engaging element; and
Fig. 6 is a perspective view of a temple with my attachment applied thereto. 7
Referring-specifically to the drawing, A designates the breastbeam of the loom, to which are applied-adj acent each end, the tem ple. supporting bracket-s B each carrying -.a
' temple slide C, the forward arm C of which supports the usual box D containing the rolls (not shown).havingthepinpoints on their peripheries for engagingv the two selvagesof the cloth to hold the latter stretched against contraction. a The letter E designates the fabric-and H the lay'of the:loom,the reeds being hown dotted. The warp threadsare designated at F, F while the filling yarn or weft thread is designated at G,the looped ends of which are indicated as G in Fig. 5. These filling yarn or selvage loops G as the case may be, are formed by the shuttle (not shown) when it commences its return trip.
The function of my invention is through the element or wire13, to engage the respective loops G as they are formed, whether they be selvage loops or the loops of filling yarn not woven into the selvage, to temporarily hold the same until they are beaten into the fabric by the reeds, in the forward imovement of the lay.
The attachment which is'the subject of this invention comprises an elongated U-shaped.
, It will be perfectly obvious that when the lay moves to the. position shown in Fig. 4 from the position shown in Fig,- 2 that the rod 8 will beforced rearwardly. e
The rearwardly extending ledge D of the temple box D has pivoted thereon, as at 95,
one end of a plate 9 having; opening from its opposite end a longitudinal slot: 9a which is adapted to receive the vertical portion 8b of the rod 8. The plate 9' functions somewhat after the fashion of an auxiliary guide but its primary function is to serve as a latch for locking the rod 8, through the rod portion 85, in a rearwardposition-there being provided a lateral notch opening from the slot 9a as clearlyindicatedin Figure 6.
Notch 9c is manually tion 8?). e
Adjustably carried by the rod v8 between the ends 7a of plate 7 is a collar 10,-there engaged with rod porbeing provided a set screw 10a for clamping the collar to therod at a predetermined point so that thet nsionof the spring 11, which is disposed between a the collar: and the reargagement of the lower beam of the 'tracted into said guide sleeve.
most upturned end 764 of plate 7, may be regulated.
To the rear end of the rod 8 is secured the block 12,the same being adjustable and adapted to be held at a predetermined point on the rod 8 by meansof a set screw 12a. The selvage or filler yarn-loop-engaging wire 13 is bra-zed or otherwise secured to the block 12 as shown and extends through afiexi'ble guide sleeve 14 which is preferably formed ofxcoi-led wire; 'The sleeve 14 extends through alined holes in the upturned plate ends 70; and projects forwardly through the hole 15a in the stud 15 which is threaded through the bracket 16. This bracket plate 16' secured against the outer end of the temple box D by means-of the maend of the wire 13 will properly engage the loop of filling yarn (or selvage loop for that matter) as the same is formed by the shuttle. Of'course the engageinent'of the wire or needle 13 with'the filling yarn or selvage loop G, is ,momentary,it being obvious that when the lay moves forward on its'beating stroke, the wire 13 will be retracted into its guide sleeve 14 through the rearward movement of rod 8 which is producedby the en lay with the trip end 8d of the rod.
Various adjustments of the stroke of: the wire 13 can be had by the manipulation or adjustment of the block 12. on the rod 8., or-
, by adjustment of the collar 10;
. The flexible guide sleeve. 14 is of the utmost importance since the projecting outer G from the wire 13 when .the same isrc Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is :t
1. A filler thread or selvage loop retainer attachment for loom temples comprising a U-shaped carrierplate having a closed longitudinal slot adapted to receive the attaching screws which mount the temple slide upon its support whereby said Ushaped plate can be adjusted withthe temple or relatively thereof, a flexible guide sleeve extending through the lateral ends of said attaching plate, alongitudinally and rotatably adjustable stud-having a transverse hole through which said guide sleeve is adaptedto extend, carrying means for said stud supportable by the outer end of the temple box, aloop-engaging wi re extending through" said guide and projecting from both ends thereof, an
end thereof serves to positively strip the loop actuator rod for said loop-engaging wire and slidably carried by the lateral ends of said carrier plate, an adjustable block mounted on the rear end of said actuator rod and to which the corresponding end of said wire is attachecl, an adjustable collar carried by the actuator rod between said lateral ends of the U-shaped carrier plate, a coil spring on said actuator rod and confined between-said collar and the laterally turned rear end of said carrier plate for normally tending to actuate said rod in a forward direction to project the forward end of the loop-engaging wire beyond the stud-carried end of said guide sleeve, the forward end of said actuator rod having a downwardly extending vertical portion and terminating in a forwardly extending lay-intercepting bumper, and a latch member carried by the temple and adapted to engage the downwardly extending portion of the actuator rod for holding it in retracted position against the action of said spring whereby to maintain the free end of the loopengaging wire retracted into the stud-carried end of its guide sleeve.
