Claims12
In a weaving system for forming a shed in a weaving machine wherein the weaving system includes heddle frames connected by way of return levers and transmission rods to oscillating members driven by a drive shaft, the improvement comprising:
- a support beam having a bottom wall, opposing side walls and opposite end walls which are close in fluid-tight relationship with respect to one another so as to permit a lubricating oil to be contained within said support beam, each of said opposing side walls including a cheek extending upwardly therefrom adjacent one end of said support beam, said opposing side walls being adapted to support the drive shaft adjacent said one end of said support beam, first pin means adapted to support the oscillating members mounted to said opposing side walls in spaced relationship from the drive shaft and adjacent one end of said support beam and second pin means spaced from said first pin means towards an opposite end of said support beam adapted to support the return levers,
- and a lubricating system mounted to said support beam for circulating lubricating oil within said support beam.
A weaving system for forming a shed in a weaving machine wherein the weaving system includes a drive shaft for imparting movement to heddle frames, comprising:
- a support beam having a bottom wall, opposite side walls, and opposing end walls which are connected in fluid-tight engagement with respect to one another, said opposite side walls including upwardly extending cheeks, first pin means mounted to said cheeks, oscillating lever members mounted to said first pin means and having end portions extending towards said bottom of said support beam, second pin means mounted to said opposing side walls in spaced relationship from said first pin means, return levers mounted to said second pin means, said return levers having end portions extending towards said bottom wall of said support beam, first rod means pivotally connecting said end portions of said oscillating levers to said end portions of said return levers and second rod means connected to said return levers and adapted to connect said return levers to the heddle frames, a lubricating system mounted to said support beam, said lubricating system including a pump connected by at least one conduit to lubricating pipes mounted adjacent said first and second pin means whereby a lubricant may be supplied at the first and second pin means.
