Abstract
Abstract Improvements in heald frame control devices wherein a toothed driving shaft is meshed with planetary pinions of similar diameter mounted on a disc. The pinions are meshed with an interiorly toothed eccentric which actuates by its smooth exterior a flange that carries a projecting appendice articulated to the corresponding oscillatory driving lever of the heald frame. The disc and eccentric are selectively retained by the respective extremities of a cranked control lever which is oscillatable about its vertex. The eccentric and flange cause a relative reciprocating movement that is transmitted to the driving lever of the heald frame whereby the control lever undergoes a movement of displacement from its articulation point that graduates the opening of the shed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
224 words
Improvements in heald frame control devices having positive countereffect movement and double lift with Open shed, comprising a toothed driving shaft, a plurality of planetary pinions disposed adjacent and in meshing interengagement with said toothed shaft, a disc disposed concentric with said shaft and having said planetary pinions rotatably mounted thereon, an eccentric member disposed for rotation concentric with said shaft and having a toothed surface disposed in meshing interengagement with said planetary pinions, said eccentric member having an actuating surface eccentrically disposed relative to the rotational axis of said shaft, a flange movably supported upon said eccentric actuating surface and having a projecting portion, an oscillatory driving lever articulated to the projecting portion of said flange, the driving lever being adapted to be connected to and cause oscillation of a heald frame, a control lever disposed adjacent the rotary shaft and angularly movable for causing a portion of said control lever to engage the disc or the eccentric member for selectively retaining same in a selected position and means for causing the control lever to undergo a movement of displacement from its articulation point for graduating the opening of the shed, whereby rotation of said eccentric member causes relative reciprocating movement of said flange relative to said eccentric member with said relative movement being transmitted through the driving lever to the heald frame.
Claim 2
Dependent Claim
224 words
Improvements in heald frame control devices having positive countereffect movement and double lift with Open shed, comprising a toothed driving shaft, a plurality of planetary pinions disposed adjacent and in meshing interengagement with said toothed shaft, a disc disposed concentric with said shaft and having said planetary pinions rotatably mounted thereon, an eccentric member disposed for rotation concentric with said shaft and having a toothed surface disposed in meshing interengagement with said planetary pinions, said eccentric member having an actuating surface eccentrically disposed relative to the rotational axis of said shaft, a flange movably supported upon said eccentric actuating surface and having a projecting portion, an oscillatory driving lever articulated to the projecting portion of said flange, the driving lever being adapted to be connected to and cause oscillation of a heald frame, a control lever disposed adjacent the rotary shaft and angularly movable for causing a portion of said control lever to engage the disc or the eccentric member for selectively retaining same in a selected position and means for causing the control lever to undergo a movement of displacement from its articulation point for graduating the opening of the shed, whereby rotation of said eccentric member causes relative reciprocating movement of said flange relative to said eccentric member with said relative movement being transmitted through the driving lever to the heald frame.
Claim 3
Dependent Claim
41 words
Improvements in heald frame control devices according to claim 1, in which at least two planetary pinions are provided and disposed on diametric opposite sides of the rotational axis of said driving shaft, said two planetary pinions being of different diameters.
Claim 4
Dependent Claim
65 words
Improvements in heald frame control devices according to claim 1, in which the planetary pinions comprise a first set of planets disposed in meshing engagement with said two shafts and a second set of planets disposed in meshing engagement with said first set and with the toothed surface of said eccentric member, said first and second sets of planets being rotatably supported upon said disc.
Claim 5
Dependent Claim
86 words
Improvements in heald frame control devices according to claim 1, in which the eccentric member has an interior toothed surface disposed in substantially concentric relationship with the rotational axis of said toothed shaft, said eccentric member further having a substantially cylindrical smooth exterior surface thereon disposed eccentrically relative to the rotational axis of said toothed shaft, said flange comprising a cranklike member having one end thereof rotatably supported upon said smooth eccentric surface, the other end of said cranklike member being articulated to said driving lever.
Claim 6
Dependent Claim
92 words
Improvements in heald frame control devices according to claim 4, in which the disc and the eccentric member each have slots on the outer peripheries thereof, and there being provided a pair of pivotal control levers with the extremity of one of said control levers being adapted to extend into the slot formed in the eccentric member and the extremity of the other control lever being adapted to extend into the slot in the disc for permitting either the eccentric member or the disc to be selectively maintained in a selected position.
Claim 7
Dependent Claim
56 words
Improvements in heald frame control devices according to claim 5, in which the control levers are mounted for pivotal movement toward and away from the disc and the eccentric member about selected pivot points, and means mounting said control levers for permitting selected movement of said pivot points relative to the rotational axis of said shaft.
Claim 8
Dependent Claim
58 words
Improvements in heald frame control devices according to claim 6, in which the mounting means includes an arm member extending radially relative to said shaft and angularly displacable substantially about the rotational axis of said shaft, said control lever being pivotally mounted on said arm at a point displaced radially outwardly from the rotational axis of said shaft.
Claim 9
Dependent Claim
35 words
Improvements in heald frame control devices according to claim 7, further including ecceNtric cam means coacting with said arm member for causing swinging movement of said arm member about the rotational axis of said shaft.
Claim 10
Dependent Claim
102 words
Improvements in heald frame control devices according to claim 1, in which a pair of control levers are provided adjacent the control device with one of said control levers being disposed for coaction with the eccentric member and the other of the control levers being disposed for coaction with the disc, one end of said control levers being disposed for coaction with said eccentric member and said disc, and the other end of said control levers being united by a linking rod provided with self-reciprocating movement, said control levers each being pivotally mounted at a point disposed between the opposite ends thereof.
Claim 11
Dependent Claim
118 words
Improvements in heald frame control devices according to claim 1, in which first and second connecting rods are pivotally interconnected to the disc and the eccentric member, respectively, said first and second connecting rods in turn being pivotally interconnected to a slideable control member and a rotational rotatable cam member disposed in driving engagement with said slideable control member for causing slideable movement thereof with the slideable movement of the control member causing a corresponding oscillation of the disc and the eccentric member due to the connecting rods disposed therebetween, said connecting rods being interconnected to said disc and said connecting member for causing oscillation thereof in opposite directions in response to reciprocation of said slideable control member.
