Definitions

  • HEALD FRAME CONTROL DEVICES This invention refers to improvements in heald frame control devices.
  • Said improvements essentially affect the form of action of the lever, or oscillator staves, from whose upper extremity effeet the control of the heald frames sending them upwards or downwards as also holding them at rest between both movements as the operation requires.
  • the driving element comprises a horizontal and longitudinally straight toothed shaft that passes through the central hole of two discs that are separated the one from the other by the thickness of the neck or rim of a connecting rod, whose projecting arm is prolonged in a flange that surrounds and articulates the aforementioned stave or lever, providing it with a reciprocating movement, which is changed in its upper resistant arm to an upward and downward movement of the heald frames, as also their period of rest.
  • an eccentrically toothed interior crown is situated in a plate provided with an exterior rim concentric with the crown and whose rim adjusts the central hole of the first disc, in whose interior face it is consolidated by points of welding or rivets to the eccentric plate with its interior toothed crown.
  • the satellite pinions gear with the toothed crown and are driven by their gearing with the horizontal shaft, each pinion being supported by smooth bolts inserted from the exterior base of the rear disc, allowing free gyration of the aforementioned satellite piflibhs.
  • Both discs are provided with two diametrically opposed slots for the operational engagement of the trigger of one or two cranked levers solidly fixed to one or two horizontal shafts which are oscillatory as the case requires, thus immovabilizing one of the discs by one or another of the peripheral slots, while the other disc remains free to turn.
  • a displacement of the cranked lever is required from its articulation point, which allows the opening and the closing of the shed to be graduated; and in order to obtain the upward and downward movements of the healds with closed shed, two opposing planetaries are provided on the same diameter, whose proper diameters differ compensating the number of their teeth.
  • FIG. 1 represents a vertical side view of the heald control device in an open shed, double lift machine without resting point.

  • FIG. 9 shows another modified device in side elevation for the healds control in an open shed, double lift machine with resting point in the up and down shed position with the possibility of semiopen shed.
  • FIG. 10 shows the device in FIG. 9 in the up shed position.

  • FIG. 13 shows a side elevation of still another heald control device of a closed shed, up and down machine, with or without resting point in the down shed and up shed position.
  • FIG. 15 shows a cfoss section of the device in FIG. 14 position.
  • FIG. 16 represents the device in FIGS. 13 and 14 in the continued movement of half shed at top shed position.
  • FIG. 17 shows a side view in elevation of a further modified device for the control of healds in a semiopen shed, double lift machine with or without resting point, in the down and up shed position.
  • FIG. 18 shows the device in FIG. 17 in the medium shed position due to the difference in the satellite pinions.
  • FIG. 19 shows the device in FIGS. 17 and 18 in the top shed position.
  • FIG. 21 shows a cross section of the device in the position FIG. 20.
  • FIG. 22 shows a side elevation of a further heald control device in an open shed, double lift machine with resting point, in the down and up shed stop position.
  • FIG. 23 shows the device in FIG. 22 in the top shed stop position.
  • FIG. 25 shows a side view in elevation of the device in FIGS. 22 and 23 in which the machine realizes the continued up and down movement of the staves.
  • FIG. 26 represents a side view in elevation of still a further modified device in an open shed double lift machine with adjustable shed resting point, in the upper and lower shed stop position.
  • FIG. 27 shows a side view in elevation of the device in FIG. 26 in the top shed stopped position.
  • FIG. 28 shows a cross section of the device in FIG. 27 position.
  • FIG. 29 shows a side view in elevation of FIGS. 26 and 27 when the machine realizes the continued up and down shed movements.
  • FIG. 30 shows a plan view of the elements comprising the heald control mechanisms used in FIGS. 1 to 12, and 26 to 29 as seen in the successive order of colocation of each of the said devices.
  • FIG. 31 shows the elements of FIG. 30 dismantled in perspective in the same order of mounting one after the other.
  • FIG. 32 represents a plan view of the elements comprising the mechanisms employed in FIGS. 13 to 21.
  • FIG. 33 shows the elements of FIG. 32 dismantled in perspective in the same order of mounting one after the other.
  • FIG. 34 represents a plan view of the elements integrating the heald control mechanisms utilized in FIGS. 22 to 25, seen in successive mounting order in each of the devices described in FIGS. 22 to 25.
  • FIG. 35 a perspective view of the elements in FIG. 34 in the same mounting order, one after another applied in FIGS. 22 to 25.
  • FIG. 40 a graph of the hook retaining eccentric of embodiment of FIGS. 5 to 8.
  • FIG. 43 a graph of the shed with 60 rest point of embodiment ofFIGS. 9 to 12.
  • FIG. 47 a graph of the open shed, double lift shed with 6 rest point of the embodiment of FIGS. 22 to 25.
  • FIG. 48 a graph of the cranked lever eccentric of the embodiment of FIGS. 22 to 25.
  • FIG. 52 shows the graph of the closed up and down shed with 60 rest point of the embodiment in FIGS. 13 to 16, with the addition of the exterior differential of the embodiment of FIGS. 36 and 37, and which provokes in the central shaft an alternating reciprocating movement of one turn to the right and another to the left.
  • FIG. 54 shows a graph of the semiopen, double lift shed with 30 rest point of the embodiment in FIGS. 17 to 21, with the addition of the exterior differential of the embodiment of FIGS. 36 and 37, and which provokes in the central shaft an alternating reciprocating movement of one turn to the right and another to the left.
  • 1 represents the driving shaft of the device, the shaft being toothed horizontally; 2 represents the eccentric disc carrier; 3 the eccentric provided with an interiorly toothed crown, eccentric 3 being fixedly connected to the carrier disc 2; 4 shows a cage of bearing needles interposed between the external eccentric surface of eccentric 3 and the interior of the connecting rod ring 5; 6 shows each one of the four satellite pinions which engage with the interiorly toothed crown of the eccentric 3 and a toothed portion of the shaft 1, and which pinions are supported on the inside face of the satellite disc carrier 7, centered to the driving shaft 1 by means of the bolts 8 (FIGS.
  • two slotted eccentrics 22 and 22 are mounted on shaft 21 for varying the position of the shafts 23 and 24, which shafts are supported in the respective extremities of the radial levers 25 and 26, with whose shafts the cranked levers 12 and 13 gyrate.
  • Levers 25 and 26 have followers engaged within the grooves of the eccentrics 22 and 22 for movement thereby.
  • Further eccentrics 22 and 22 are angularly movable in opposite directions as is evident from inspection of FIGS. 9 and 10.
  • the variation in FIGS. 17 to 21 consists of the provision of the compensated change in the number of teeth in two of the opposing satellite pinions 27 and 28 on the same diameter and in a determined number of teeth, so that in the opposing position of said pinions, the lever 16 shall not arrive at the medium shed, as much in the up as in the down position; by this means the semiopen double lift shed is attained.
  • the rotational movement of the main shaft 1 thus causes a free wheeling of the disc 7, the eccentric 3 being nonrotatably locked in position so as to also maintain the stave 16 locked in one of its extreme end positions, which in turn results in the heald being maintained in a stationary position.
