Oscillator system for paper machine

Claim 1

An oscillating device to apply oscillation to a relatively moveable component of a paper machine, comprising a prime mover locatable remotely from the machine mechanically connected in driving relation with liquid pump means, said pump means being connected in liquid transfer relation with an oscillator means, said liquid pump means comprising a first compressible bag and a second compressible bag arranged in mutually opposed compressing relation within restraining frame means, said prime mover being arranged to provide alternate cyclic compression of said pump bags, said oscillator means comprising a third compressible bag and a fourth compressible bag arranged in mutually opposed compressing relation within restraining frame means, linkage means connecting said oscillator means to said machine component, said first bag being connected in liquid transfer relation solely with said third bag and said second bag being connected in liquid transfer relation solely with said fourth bag whereby in operation, on actuation of said prime mover to compress said first bag liquid is transferred therefrom to said third bag to cause expansion thereof, thereby moving said linkage means and said machine component, said expansion of said third bag compressing said fourth bag to transfer liquid to said second bag in expanding relation therewith.
