Definitions

  • tive length is adapted to be gradually shortened by the action of a pawl on a combined bevel and ratchet wheel rotatable on the fulcrum pin of the main lever and meshed with a bevel wheel secured to a screw as sociated with the lever-and fitted with a nut connected to the reciprocating member;
  • the pawl is stationarily pivoted, and adjustably fixed to the fulcrum pin of the swinging lever is a regulator adapted during its oscillations to alternately lift said pawl and then allow it to drop into engagement with the teeth of the ratchet wheel, the amount of rotation imparted to the screw during each complete oscillation being determined by the setting of the regulator.
  • Figures 2 and 3 are front elevation and plan respectively of Figure 1.
  • Figure 4 is a diagrammatic view showing the principle on which the invention is based.
  • the reciprocating member or travarrangement being such as to progressively wheel.
  • erse bar 1 is adapted to have motion imparted to it through the medium of a swinging lever 2 suspended vertically from and fixed to a fulcrum pin 3 and oscillated over a defined distance by a cam 4 acting through a bar 5 and pin 6, whilst in a slot in the lower part of the lever 2 is fitted a nut 7 in the form of a crosshead which iscapable of being moved by means of a screw 8 associated with the lever 2, to any position in the slot. Projections 9 on the crosshead 7 are girdled by a link 10 which is coupled to the traverse bar 1.
  • the screw 8 is rotated automatically by the action of a pawl 11 on a combined bevel and ratchet wheel 12 which is rotatable on the fulcrum pin 3 of the main lever 2 and is meshed with a bevel wheel 13 keyed to the top of the screw 8, whilst the lift of the screw 8 is regulated by means of a regulator 14 adjustably fixed tothe fulcrum pin 3 and which fits closely over the teeth of the ratchet wheel 12 in such a manner that the pawl 11 is allowed during each oscillation to engage the teeth of the ratchet wheel 12 and thereby impart rotary motion to the bevel wheel 13 and screw 8 thus lifting the crosshead 7 a given amount for each complete oscillation of the lever 2.
  • the cam 4 is rotated and oscillates the lever 2 and screw 8 through the medium of the bar 5 and pin 6 thus imparting a reciprocating motion to the traverse bar 1 which is pivotally connected to the crosshead 7 on the end of the screw 8 and between the two parts of the slotted lever 2.
  • the traverse bar 1 is moved in the direction of the arrow A, the combined bevel and ratchet wheel 12 is rotated anti-clockwise through the medium of the bevel wheel 13 until the regulator 14 allows the pawl 11 to drop on to the ratchet Any further oscillation of the lever 2 causes the combined bevel and ratchet wheel 12 to rotate the bevel wheel 13 and screw 8, thus raising the crosshead 7.
  • Spring-pressed pawls 15 are pivoted on the lever 2 and therefore move with same and with the wheel 12 during its anti-clockwise movement until pawl 11 drops and engages the teeth of the wheel 12 so as to arrest its anti-clockwise rotation, whereupon the pawls 15 ride over the teeth of the wheel 12 until the end of the swing.
  • the return stroke i. e. when the traverse bar 1 is moved in the direction of the arrow B
  • the combined bevel and ratchet wheel 12 is rotated clockwise through the medium of the bevel wheel 13 and the spring-pressed locking pawls 15 pivoted to the lever 2, and the regulator 14 lifts the pawl 11 in readiness for the next stroke.
  • Figure 4 shows how, by shortening the distance between the fulcrum 3 and crosshead 7 the movement of the traverse bar 1 is reduced in proportion (since the main lever 2 is always swinging through the same are) thus producing an inclined face. 15 on the yarn or like material being wound on the bobbin 16.
  • I claim 1 In a mechanism for the purpose described, the combination of a reciprocating traverse bar, a lever having a cross-head adjustable lengthwise thereof and connected to said bar, a screw for moving the cross-head longitudinally of the lever, gearing connected to the screw and oscillating with the lever, a stationary pawl adapted to engage the gearing at each oscillation of the lever, a cam for oscillating the lever, and a regulator adjustably mounted at the axis of the lever and cooperating with the pawl for determining the period of engagement between the pawl and gearing.
  • a swinging lever depending from a relatively fixed fulcrum, means for oscillating said lever, a screw extending longitudinally of the lever, a crosshead on the lever engaged with said screw, a reciprocat'ory bar connected to the crosshe'ad, a gear secured to the upper end of the screw, a second gear mounted to turn about the axis of the lever and engaging the gear on the screw, a ratchet connected with the second said gear, a stationary pawl adapted to engage the ratchet and move the same during a portion of each oscillation of the lever, and adjustable means for varying the length of time that the pawl will thus engage the ratchet.
