LOOM FOR "WEAVINQ Application filed September 26, 1928, Serial No. 308,394, and in Great Britain July 2, 1927,

This invention relates to looms for Weaving with more particular reference to those which are fitted With automatic weft replenishing mechanism, and has for its object to devise improvements in the construction and arrangement of such mechanisms which will enable fine quality fabrics to be Woven upon such looms.

rlhe invention consists inthe provision of means for preventing what is knovvn as `aV double pick, that is the carrying into the shed of any loose weft ends that may be left v Vfrom a discharged cop or` cut from the cloth selvedge.

The accompanying drawings illustrate one mode of carrying out the invention :--l

Figure l is a more or less diagrammatic plan showing a part of the breast beam of a loom and sley with parts mounted and arranged thereon in accordance With the invention; A

rFigure 2 is an elevation'of .the end of the sley at the transfer end of the loom, and

Figures 3 and 4 are tvvo views illustrating u a detail.

In carryingv our invention into eect We may apply our improvements to existing looms or to looms specially built for the purpose, and such looms are provided With the usual accessories incidental to weft replenishing looms, that is to say, With some form of magazine (not shown) for'the cops and With atransferrer a on a hammer shaft for the purpose of pushing a full cop into the shuttle and simultaneously ejecting'- therefrom the empty cop Whenever the vveft requires replenishing.

We also provide the usual weft fork and hammer mechanism (not shown) for bringing into operation the weft replenishing means such as is commonly employed on automatic weft replenishing looms.

For the purpose of cutting thel tag endsl of the cloth selvedge Wev provide a suitabley cramp and scissors mechanism' and in order to dispose effectively of the Weft ends cut olf bythe scissors, We arrange the weft to pass from the shuttle under or round a stationary hook member c1 (Figure l) and adjacent to said hook member We provide a particular type or construction of Weft retoothed quadrant arm c2 mounted` on a bracket 03 on the transfer shaft lo and opverated by a bunter 0G on the sley. The

b unter c6 contacts With the roller or projection c5 on the arm c2 When the transfer shaft 55 lo 1s rotated during operation of the Weft replenishing mechanism sof as to move the armagainst its controlling spring c4 and thusv clear a-Way any loose vveft ends that vI might .otherwise interfere With the Weaving G0 operation. p. y

Furthermore, for the purpose of preventl ing Vvvhat has hitherto been a considerable difliculty in connectionA with weft replenishing looms, namely, the possibility of ay doublepick or the carrying into the shedv of loose weft ends left after discharge of the pirn from 'the shuttle boX We arrange the checking straps at the back of the sley or provide an iron rod or Bovvdenwire a (Fig-f F ure l) fixed behind the hand-rail containing leather tag ends Lol which Workin vthe same Way as the check strap usually arranged in kthe front of the sley, andin this Way We are enabled to forma slot or opening u2 (Figure 75 2) in the sley block, andin a suitable posi- Y Aend of weft so as to dravvv the same avvayv from. the clothand prevent the Weft end from being carried into the-shed.

Moreover, We prefer also to provide a pirn chute w1` (Figure 2) beneath the shuttle box Which makes it possible for the pirns to drop straight dovvn into the empty pirn can so thatthere Will be no fear ofthe pirns rebounding in such a manner as might other- Wise prevent-the shuttle from being discharged from the shuttle boX. SuchV chutev may also have a leather ory like guide .or buffer co2 to assist in .guiding the pirn into the pirn can. 95

It Will be understood that the inventionl is not to be limited to the foregoing'details of construction which are given by Way of example only, nor is it to belimited to any plenishing loom to which it is to be applied. a sley, a bunter on said sley7 and means on 1() Having now described our invent-ion, what said hook member adapted to be engaged by We claim as new and desire to secure by ksaid bunter during Weft replenishment to Letters Patent is rock said hook member to weft engaging In anV automatic weft replenishing loom, position.
