Definitions

  • This invention relates, to loom lays and more particularly to the shuttle boxes of lays and it is the general object of the invention to'provide ready means for locating the 'po-' sitign of the box back with respect to.
  • the usual loom'lay carries an upright reed and has at each end a shuttle box the back of which is usually substantially but not 19 strictlyin line with the reed, so that the shut- .tle may pass from one box to the other through-the shed and be properly aligned with the reed.
  • the shuttle'box is made up in part by a back the position of which is determined by the lay sword.
  • Fig. 1 is a front elevation of a portion of a lay made according to my invention, certainlparts being removed for the sake of clearness,
  • Fig.2 is a top plan view of thesingle box end of the lay as it would be seen by an observer standing behind the lay, certainparts being broken away to illustrate the invention more fully,
  • Fig. 3 is adetailed rear elevation taken in the direction of arrow 3, Fig.2,
  • Fig. 4 is a'view similar to Fig. 2 but show ing the drop box end of the lay
  • Fig. 5 is a rear elevation taken in the direction of arrow 5, Fig. 4,
  • Fig. 6 is an enlarged vertical section taken on line 6-6of Fig. 1, and
  • Fig.7 is a detail end elevation of a portion of the adjusting mechanism takenin the direction of arrow 7 Fig. 5.
  • a lay 10 which is mounted on lay swords 11 and 12 located. respectively at the right and left hand sides of the loom.
  • the swords project above the lay'beam as shown in Fig. 1 and have their upper ends connected by a hand raill3.
  • the lay is provided with a longitudinal upwardly opening groove 14 which receives the lower bar 15 of a reed R.
  • the upper bar position upon the upper ends of the swords '32 are smaller positioning screws 34-,
  • a loom as set for h herein for purposes oi illustration is assumed to be a 4 x 1. that is, there is a single box 20 on one end of the lay and there are shifting shuttle boxes 21 on the ther end of the
  • the single box 20 as shown more particularly in F is defined by a box back 22 having a v ical wall. 20.
  • Said box bacl has e ending rearwardly therefrom a pair of cars 2% through which extends an adjusting bolt 25. This bolt extends into the lay adjacent the o ter portion of one end thereof and is the means for l'iolding the out-er part of the box back in position.
  • a binder 26 of usual form may be employed for the frontoi the box while the bottom of thbox may be formed of a plate 27.
  • a hr cket Secured to the rear portion of the lay by means of screws 28 is a hr cket which extends across the sword as shown in Fig. 2.
  • Said bracket may be formed with a pair of cars 30 which afford support for the forward end of one of the connectors for the lay, not shown.
  • the upper end of the bracket 29 is provided with means for supporting the inner portion 31 of the box back.
  • a relal rely large screw 32 passes freely through the plate or bracket 29 and also through the sword 11, having its forward end tapped or threaded intothe portion 31 of the box back india ted at By means of this screw 32 the inner portion 31 of the box bacl: may be drawn toward the bracket or plate 29.
  • screws 3 is the screw 3" is such that it will never project bey nd the surface 23 to interfere with the flignt of the shuttle.
  • a similar ad ustmcnt in the opposite direction can be made if the surface 23 is behind its proper position. Such an ustment can be compensated for by putting shims under the ears 24:, either in front oi. or behind the bolt 25, or the box back may e subjected to a very slight twist, keeping tl e bolt and ears in their original position.
  • the angle of the surface 23 may be changed by moving through a vertical plane.
  • the box back 23 is positioned entirely by means of the screws and 3st and is not in Contact with the lay sword 11 bein .Lpil" rated from the latter by the space 38.
  • the location of the guide groove 51 may be changed in a direction transversely of the reed line by varying the position of the smaller screws 58 and it will further be seen that by varying the position of the screw 54; the plate 52 may be moved rearwardly as a whole around the bolt 53 as a center. It will therefore be seen that in connection with the drop boxes the guide for the inner end of the lay may be changedso as to keep the boxesat the shifting box end of the loom in proper alignment with the reed.
  • the outer end of the shifting boxes may be ad justed in any approved manner as for instance by the construction set forth incopendingapplication filed by Bergstr in ct to be understood oi course that the length Of 211., Sci. No. 321,204.
  • a member independent of i the reed supported by the lay and in sub- 1 stantial alignmentwith the reed to guide the screw means supported by the lay and ex tending and movable transversely of the reed to position the member relatively to the reed, andother screw means positioned with respect to the lay and having operative engagement with the member to move and hold the latter against the first named screw means.
  • a member supported by the lay to be engaged by and guide the shuttle, a plate fixed with respect to the lay, a plurality of positioning screws threaded through the plate and extendingtransverse- 1y of the reed to engage and position the member, and a retaining screw movable tranversely of the read and limited as to move ment in one direction by the plate and threaded into the member to be capable of drawing the latter toward the plate and varying the position of the member relatively to the reed.
  • a loom lay having a reed along which a shuttle may run, a member supported by the lay to be engaged by and guide the shuttle, a plate fixed with respect to the lay, a retaining screw extending through the plate and limited as to movement in one direction by the latter and having operative engage- I ment with the member to move thelatter toward theplate, and positioning screws nor mally fixedwith respect to the lay to engage the member above and below the first named screw, said positioning screws being movable transversely of the reed to vary the position of the member relatively to the reed.

  • each of said means operatively related to the member and each. movable transversely of the reed. to give the member a plurality of positions Pansversely oi the reed, and movable shuttle boxes guided by the member.
