Definitions

  • TEXT ILE MACHINE Filed Oct. 2, 1936 4 Sheets-Sheet 3 ATTORNEYS Nov. 8, 1938.
  • the new device When used for controlling the operation of a loom, the new device makes useof a pattern sheet carrying a representation of the design to be reproduced and it includes devices for operating the heddles selectively, these devices being controlled by mechanism which scans theppattern sheet.
  • the apparatus thus takes the place of a Jacquard mechanism and obviates the necessity of preparing a set of punched cards for each type of fabric to be woven.
  • the use of the new apparatus consequently simplifies and reduces the cost of manufacturing patterned fabrics to an important extent.
  • Figures 3 and 4 are enlarged fragmentary vertical sectional views of parts shown in Figure 1, illustrating the parts at different stages in the operation of the apparatus;
  • the pattern and'scanning mechanism used for controlling the supply of current to the electrcmagnets 50a, 50b may take various forms as, for example, the scanning mechanism may be of the photo-electric "or direct contact types, ch as are disclosed in the copending' application of Fisher, Tandler, and Carlisle, Serial No. 92,112,
  • the rotating shaft 29 acting through the cranks 21, 28 and the links 25, 26, causes the levers l8 to be rocked in a clockwise direction about the spindle H, the levers being restored to their original positions by the springs 20.
  • 1 swing down, permitting the arms I 3 of the control members 2 to move down with the bar B.
  • the selection of the control members is efl'ected by means of a plurality of selector elements 4
  • Each selector element is provided with a hook 43 which, upon appropriate movement of its selector element, can be brought in position to engage a projection 44 on its associated control member, this projection having a face substantially radial with respect to the axis of spindle II and to be engaged by its hook 43 and another face 45 which lies at an angle to the radial face.
  • the selective operation of the selector elements is accomplished by means of an electro-mechanical actuating device generally designated 46 which is mounted on a carriage 41 moved back and forth across the loom on a rail 48 supported on the members I0 in any suitable way.
  • the actuating device 46 may take various forms, but in the construction illustrated, it includes a pivotally mounted hammer 49 whichserves as, or is attached to, the armature of a pair of electro-magnets 50a, 50b attached to the carriage 41. These electro-magnets are energized and deenergized alternately under the con trol ofa scanning mechanism, and each electromagnet is connected through its own supply lines 5
  • This'pattern sheet is attached at one end to a rotary support 30 56 which is rotated with a stepwise motion by means not shown during the operation pf the loom.
  • a light current is supplied to the sheet in any suitable way, as by a line 51 connected through the amplifier to the source of energy, 35
  • a scanning element 58 in the form of .a roller mounted on a spindle 59 supported in the carriage 41, the roller being pressed yieldingly against the sheet by a-spring 60 encircling the spindle.
  • leading from the spindle completes the circuit.
  • the Selector elements the pat- 25 are all in a position in which 7 their hooks are out from in front of the projections on their associated control members, and in the first traverse of the carriage across the loom,
  • certain of the selector members are selected and moved to effective position with their hooks in front of the projections on their associated control members.
  • the levers l8 are swung clockwise by the action of cranks 25, 26 and associated parts, and move the bar l6 down.
  • the control members, whose selector elements have been selected move clockwisewith the downward movement of the bar It to a slight extent, until their projections are engaged by the hooks on their selector elements, after which those members are restrained against further clockwise movement with the bar It.
  • the shuttle or needle is now passed through the shed, and at the same makes a return movement across the loom, during which the selection for the next shed is effected.
  • the pattern may require that certain selector elements previously effective should be restored to ineffective position, andthe elements are freelymovable for that purpose since their associated control members have been swung counter-clockwise by the action of the knife bar 33.
  • Other selector elements will then either be left in efiective position or be moved to effective position by the electro-magnetic actuating device.
  • a spring plate 62 extending across the loom and carried by suitable supports 63 movably mounted in guide-ways in the members l0.
  • Each support 63 is connected by a link 64 to an arm 65 fast on a shaft 66 mounted in the members I!) and provided withan arm 61 carrying a roller 61a bearing on a cam 68 fast on shaft 40.
  • the apparatus includes control members l2 mounted on aspindle l l and selectively restrained by selector elements 4
  • the selector elements must be set up for the next shedding operation, and this necessitates that all the selector elements including those which have been eiiective, should be freely movable.
  • the knife bar 11 is provided for this purpose, and as the levers I0 move down, the bar is moved inover the arms I of the control members I3 which have been restrained by their selector elements.
  • the shape, of the under surface of the bar is such that in its inward movement, it forces the arms l4 downward to a slight extent and thereby moves the previously restrained control members clockwise to an amount suflicient to release the hooks of their associated selector elements.
  • the new apparatus thus takes the place of a Jacquard mechanism and eliminates the use both of a set-of punched cards and of the card barrel,,needles, hooked wires, and lifting apparatus of such a mechanism.
  • the pattern sheet'employed with the new control carries a representation of the design which is to be reproduced, and since such a sheet can be made at much less cost than the set of cards which would be necessary with a Jacquard mechanism'to reproduce the pattern, the use of ,the new apparatus reduces the cost not only of the equipment, but also of operation in the weaving of figured fabrics.
