Definitions

  • This invention relates to a guiding attachment for a heddle supporting shaft of the loom.
  • Such attachment permits the operation of heddle supporting shafts of large dimension in such a manner that confronting attachments do not touch while they are moving in either the upward or the downward direction.
  • the invention has among its objects the provision of a guiding attachment for heddle supporting shafts which is securely and rigidly attached to the shaft, which may be made of any necessary vertical dimension. and nevertheless will not interfere with the use of warp threading machines.
  • the guiding attachment is constructed of several superposed parts, and preferably in two parts or sections of which the first section is rigidly connected with the heddle supporting shaft while the second section is detachably connected to the first section.
  • FIG. I is a view in front elevation of a heddle supporting shaft of the loom, the shaft being provided with two guiding attachments;
  • FIG. 2 is an enlarged view in front elevation of a first embodiment of guiding attachment in accordance with the invention. such attachment being shown secured to the lower portion of the heddle supporting shaft, shown in FIG. 1;
  • FIG. 3 is a view in vertical cross-section to the guiding attachment, shown in FIG. 2, the section being taken along the line lll-
  • FIG. 4 is a view in front elevation of a second embodiment of guiding attachment connected to the lower portion of the heddle supporting shaft of the loom;
  • FIG. 5 is a view in side elevation of the guiding attachment shown in FIG. 4, the view being taken from the point of view line 55 in FIG. 4;
  • FIG. 6 is an exploded view in front elevation of the second embodiment of guiding attachment, shown in FIG. 4;
  • FIG. 7 is an exploded view in side elevation of the guiding attachment, shown in FIG. 6, the view being taken from the line 7-7 in FIG. 6.
  • FIG. 1 there is shown a heddle supporting shaft of the loom, such shaft consisting mainly of parallel upper and lower shaft rod 1 and 2, respectively, which are connected by longitudinally spaced parallel side supports 3 and 4.
  • the upper and lower shaft rods 2 are provided with heddle supporting channel formations 5 and 6 respectively, and with upper and lower guiding attachments 7 and 8, respectively. Since the guiding attachments 7 and 8 are similar, except for being disposed in mirror-image relationship with respect to each other, a detailed description of the lower guiding attachment 8, shown in detail in FIGS. 2 and 3, will suffree.
  • the guiding attachment 8 is composed of an upper part 9 and a lower part 10, the two parts being detachably connected to each other. Parts 9 and 10 are advantageously made of wood.
  • the upper part 9 has a central channel 18 therein which snugly receives the lower shaft rod 2 and is rigidly attached thereto as by gluing and the like.
  • the two parts 9 and 10 are of flat, relatively narrow dimensions, such parts being maintained in a lined coplaner relationship by a tongue and groove connection, generally indicated at 12, in this instance the tongue being located on the upper part 9 and the groove being disposed in the lower part 10 of the guiding attachment.
  • the parts 9 and 10 are securely connected together in aligned relationship by a screw 11 which is disposed with its head in a laterally central bore 16 in a part l0, the shank of the screw extending upwardly through a smaller bore at the upper end of the bore 16 and into an insert l5 having internal threads 17.
  • the screw preferably, has a hexagonally socketed head so that it can be turned by an Allen wrench.
  • the insert 15 is preferably made ofa synthetic resin, such as nylon, having a relatively high coefficient of friction with the metal of the screw 11 so that once tightened the screw I1 is virtually locked from becoming loosened and accidentally unscrewed.
  • the lower end of the bore 16 in the part 10 is provided with an inserted sleeve 13 having an inner diameter which is smaller than the outer diameter of the head of the screw 1].
  • the sleeve 13 preferably has the lower end of the bore therein flat or beveled, as shown at 14, so as to facilitate the insertion thereinto of the above-mentioned Allen wrench for assembling and disassembling the parts 9 and 10 through turning of the screw 11 in the appropriate direction.
  • the attachment is likewise made in two parts, the first for upper part, being designated 9', and the second or lower part being designated 10'.
  • the upper or the first part of the attachment receives the shaft rod 2 in a central slot or groove 18' therein, the parts being rigidly connected as by gluing.
  • Parts 9' and 10' are connected at a tongue and groove connection 12', the tongue in this instance being disposed on the part 10' and groove being on the part 9.
  • the screw and nut employed for securing the two parts of the guiding arrangement together in the first embodiment
  • in the second embodiment there are employed quickly and easily operated matching arrangements for this purpose.
  • the righthand edge of the assembled parts 9', 10' are provided with a central vertically extending groove of which the section in the part 9 is designated 19 and the section in the part 10' is designated 29.
  • a similar but oppositely disposed groove is provided in the left hand edge of the assembled parts 9'. 10', the section of such-groove in part 9' being designated 20 and the section in part 10' being designated 30. Spanning the section 19 of the groove and the right-hand edge of part 9 is a cross pin 21, and spanning the section 20 of the groove in the left hand edge of the part 9' is a cross pin 22.
  • Similar but oppositely disposed levers 2S and 26 are pivotally mounted upon pivot pins 27 and 28 which span the groove sections 29 and respectively in part 10, the levers 25 and 26 lying partially in the groove sections in the respective parts 9', 10'.
  • the upper ends of the levers 25 and 26 are provided with inwardly open, confronting slots which receive the respective cross pins 21 and 22.
  • the levers 25 and 26 are constantly urged into a latching position by coil compression springs 33 and 34. disposed in blind bores 35 and 36 respectively in the part 10'.
  • the springs 33 and 34 act compressively upon the respective levers 25 and 26 in order to thrust them into their latching position.
  • Such springs can be overcome, however, so that the levers may be swung to free the cross pins from the slots in the levers by pressing together projections or buttons 31 and 32 which are provided on the lower ends of the levers 25 and 26 respectively.
  • buttons 31 and 32 which are provided on the lower ends of the levers 25 and 26 respectively.
  • such buttons normally projecting at a substantial distance beyond the respective side edge of the part 10' in order to be readily engaged by the hand of an operator.
  • a multi-part guiding attachment for heddle sup- 5 porting shafts of looms comprising a first part rigidly connected to the shaft, and a second part detachably connected to such first part.
  • a guiding attachment according to claim 1 wherein the parts are aligned in a common plane 0 through a tongue and groove connection.
  • a guiding attachment accordinging to claim 4, wherein the shell has an enlarged outer end to facilitate the insertion of an Allen wrench.
  • a guiding attachment according to claim 7, wherein the latch arrangement comprises a spring loaded latch disposed on a side edge of and pivotally situated in the second part of the attachment, such latch cooperating together with a cross pin which is arranged in an opensided recess in the first part of the attachment.
  • a guiding attachment according to claim 8 comprising two similar latch arrangements disposed on opposite side edges of the second part of the attachment.
  • a guiding arrangement according to claim 9, wherein the latch arrangements are flat levers disposed in recesses on the side edges of the second detachable part, and comprising springs inserted in blind holes in the second part. said levers have knobs which partially protrude from the second part of the guiding attachment.
