  • ABSTRACT 1221 Filed: on. 23, 1973 Appl 408692
  • An improved connecting means for operably connecting a loom drive to a harness controlling and a color controlling selector dobbies wherein axially moveable 3 139/324 clutch and spline connections are used to disengage (511 int. D03c 13/00 the main loom drive while permitting the dobbies to 139/1 R. I be simultaneously operated by other means. such as by a hand wheel or crank.
  • FIG. is a partially schematic perspective view of a typical loom showing both the color selector and harness controlling dobbies together with the improved connecting mechanism of this invention
  • FIG. 2 is a front perspective showing the improved connecting mechanism
  • FIG. 3 is a front perspective of the improved connecting mechanism showing the parts in the position where the loom drive has been rendered ineffective
  • FIG. 4 is a sectional view taken along the line for FIG. 3.
  • FIG. I the numeral indicates the overall loom which also includes the first dobby II that controls the harness frames, which are shown in phantom by and are indicated by the numeral I2.
  • the first dobby I1 is controlled by means of the punched tape 15 while the second dobby is controlled by means of the punched tape 16, both in conventional manner.
  • the loom also contains a suitable drive means which is here indicated as being a bevel drive 17 that is connected to a motor (not shown) located on the lower right hand side of the drawing in FIG. I.
  • the bevel drive I7 has an output drive shaft I8 around which is entrained a drive chain 19.
  • the improved connecting means 25 of this invention comprises a main dobby drive shaft 26 which is mounted for rotation in the journals 27 and 28 located adjacent to each end of the drive shaft 26.
  • the main dobby drive shaft 26 includes splined connection 29 located between the two journal points to allow for axial movement between cooperating parts of the shaft. for reasons which will be subsequently explained.
  • a first means 30 that is here shown as a gear or a sprocket and which is operably associated with a clutching device that will be more fully explained hereinafter and is connected to the bevel drive I7 by means of the previously mentioned drive shaft [8 and drive chain 19.
  • the second means 31 fixed on main dobby drive shaft 26 is also here shown as a sprocket although other means could as well be used.
  • the second means 31 drives a chain 32 and this chain is responsible for operating the first dobby II, which is in turn controlled in its operation by means of the dobby tape 15.
  • the third means mounted on and for rotation with shaft 26 is a gear or sprocket 33 that cooperates with a chain 36 which in turn is connected through appropriate gearing to the gear reduction box 35.
  • the gear reduction box which contain a driving worm gear. is responsible for rotation of the connecting shaft 37.
  • the connecting shaft 37, through the linkage just mentioned before is driven by bevel drive 17, and in turn effects the movement of chain 39 through sprocket 38.
  • Chain 39 is operably connected to the second dobby l3 and thereby effects operation of this part of the apparatus.
  • the next element ofthe improved connecting means that is rotated by means of main dobby drive shaft 26 is the gear means 40 which is clearly shown in FIGS. 2 and 3 of the drawings.
  • the gear means 40 is itself mounted on a collar 41 which is secured to the main drive shaft 26.
  • the collar 41 also includes a flange 42 on its left most end and a clutching dog 43 on the end which is furthest to the right (as seen in the Figures).
  • the clutching dog 43 cooperates with a corresponding dog 44 that is formed on the first driving gear means 30.
  • the last element carried on collar 41 is the timing plate 45 which has the configuration shown in FIG. 4. It can be seen that plate 45 has a relieved or removed portion 46 but otherwise has a substantially larger diameter than the diameter of the gear means 40. In order for collar 41 to be moved axially away from the drive sprocket 30, it will be necessary for the timing plate to be in the position shown in FIG. 4. In any other position the enlarged portion of plate 45 will contact the end wall of the smaller of the two gears shown in FIG. 4 and axial movement will not be possible.
  • FIGS. 2 and 3 there is provided an elongated shaft which extends substantially co-axially with the main dobby drive shaft 26.
  • This shaft is constructed in two sections, the first being an enlarged tubular section 50 of a preselected inner diameter and the second being a smaller solid shaft 52 having an outside diameter that can be inserted into the tubular shaft 50.
  • the larger of the two shaft portions, 50 is shown as having a hand wheel 51 mounted on its end while the smaller of the two shaft portions, 52, is shown as having gear means 56 attached to it for rotation with that shaft member.
  • There is also a spline element 55 which has outwardly extending portions that fit around the collar 41 and which abuts against the flange 42. This spline is secured to the tubular member 50.
  • portion 50 In order that the portion 50 might move axially with respect to portion 56 the two parts of the shaft are assembled together with a key that requires both shaft members to rotate simultaneously but which key fits in an elongated slot formed in the shaft member 50 so that this part of the shaft combination can be moved axially back and forth without requiring similar movement of portion 52 of the shaft combination.
  • the shaft 50 and its related parts it will be necessary for the operator to in sure that the relieved portion 46 of timing plate 45 is in the clear position, as indicated in FIG. 4. lfa portion of the timing plate 45 overlaps gear means 56 then the operator must turn the loom by hand until the angular position of the shaft 26 is such that the cutaway portion 46 will be adjacent to the gear means 56.
  • the operator upon effecting the axial movement of the shaft 50 and spline 55 and gear means 40 can manually turn the shaft 50 and through the means that keys it to the shaft portion 52 and turn the gear means 56. Rotation of gear means 56 results in movement of gear means 40 and this in turn will cause movement of the harness frames and also of the yarn controlling fingers 14.
  • the operator need only back the loom up to the point where the missing pick is located. remove the pick. and then once again commence operation of the loom. Since the color dobby l3 and the frame dobby 11 are directly interrelated by means of the present mechanism, it will automatically assure that the tape controls 15 and 16 are again synchronized to present the proper weft yarn for insertion into the warp shed.
  • said improved connecting means includes means for disengaging the drive means therefrom.
  • said improved connecting means includes gear means mounted for axial movement therealong and wherein said means operatively connected with said improved connecting means includes gear means for mating with said axially movable gear means to effect rotation thereof.
  • first means mounted on said main drive shaft said first means being operably connectable to the drive rotation therewith and for axial movement therealong to be engaged with and disengaged from said first means as desired
