Title: Improved paddle machines for treating textile and like goods with liquids
Inventor: FREEMAN SAMUEL RICHARD THOMPSO
IPC: D06B5/12
Filed: 1958-01-21
Abstract: <PICT:0854619/IV (c)/1> <PICT:0854619/IV (c)/2> <PICT:0854619/IV (c)/3> <PICT:0854619/IV (c)/4> <PICT:0854619/IV (c)/5> <PICT:0854619/IV (c)/6> <PICT:0854619/IV (c)/7> A dyeing machine is characterized by a rotary multi-bladed paddle, the inner portions of the blades of which are articulated to members by means of which the blades are pivotally connected to blade-adjusting components, these components being turnable in either direction about the axis of the shaft of the paddle to effect either simultaneous radial projection or retraction of the blades and the components being adapted to be locked together and to the connecting members, after a desired adjustment has been made to prevent relative turning movement between the components and the shaft.  As shown in Fig. 3, the paddle may have five equi-angularly spaced blades A, B, C, D, E.  The blade-adjusting components may consist of discs 6, 7 (see Fig. 2) connected to the blades by links a, b, c, d, e, themselves keyed to a sleeve 8 mounted upon and rotatable about shaft 5.  Sleeve 8 may be screw-threaded to receive locking ring 9 which may act as a clamp on disc 10 whereby discs 6, 7 and links a-e are held firmly. Spacer washer 13 may serve not only to space apart and so prevent interference between links a, c, d, but also may function when locking ring 9 is screwed up to transmit the locking action from links a, c at the inner side of disc 6 to link d at the opposite side of disc 7.  Thus by manipulating locking ring 9 on sleeve 8 the desired projection or retraction of blades A-E can be achieved.  Each blade A-E may have associated with it a mainly flat plate 15 which extends transversely right across the paddle from one circular end plate 1 to the other, the plate constituting a fixed inner section of the blade in relation to which the movable section of the blade is slidable radially inwards and outwards.  Opposite marginal end portions of each transverse plate 15 may be bent at right angles to form flanges 15a by means of which the plate is secured e.g. by welding to the inner opposed faces of the circular end plates 1.  Two narrow flat strips 16 of metal may extend alongside flanges 15a and serve as slideways upon which the adjustable blade may slide whenever it is adjusted.  The inwardly directed portions of flanges 14a of the pair of guide angles 14 for each paddle blade may extend over the margins of the latter as shown in Fig. 7 such that the blade when adjusted may slide between the flanges and strips 16.  The back of the central portion of the flange of the blade may have secured thereto a U or forked block 18 to receive the relevant end of the corresponding link to which it is pivoted by a pin 19.
