Definitions

  • This invention relates'to improvements in flatwork ironing machines of the type in which the work passes between a roller and a curved bed, the bed being formed of two arcuate sections, or two series of arcuate sections embracing about 180 of the periphery of the roller, each section or each series of sections being pivotally mounted so that they can be moved to and from the roller surface for the purpose of applying the necessary pressure between the roller and the bed when the machine i in operation and to be moved from the roller when the machine is inoperative.
  • the principal object of the present invention is to provide means for operating the sections or series of sections so that both sections or both series of sections will be applied with a predetermined pressure ratio to the periphery of the roller, and to so arrange and operate the sections that distortion of the bed is obviated or reduced to a minimum thereby making it possible to employ a long roller without the pressure between it and the bed differing at different parts of its length.
  • the pairof sections or each pair of sections of thebed are supported by balanced interconnected linkage systems controlled from a common source of power whereby the sections will apply equal pressure or pressure at a predetermined ratio to the roller and when the operating power is removed will automatically fall away from contact with the roller.
  • Fig. 1 is an end elevation of the machine showing the sections in their operative positions
  • - Fig. 2 is a similar end elevation, with the frame of the machine removed, showing the sections moved away from the roller,
  • Fig. 3 is a part front elevation of the machine showing three sections forming one part of the bed; 7
  • Fig. 4' is an elevation of one of the sections
  • Fig. 5 is a transverse section thereof
  • Fig. 6 is a longitudinal section of the roller
  • Fig. 7 is a section on line l! of Fig. 6.
  • the frame of the machine comprises two end members A. of substantially triangular shape connected by two longitudinal members A preferably in the form of angle irons, and a series of transverse members A also preferably in the form of angle irons.
  • the transverse members A form supports 0 a stationary longitudinal rod B extending longitudinally from end to end of the machine and the end frames A carry the bearings c for the shaft C of the roller C, which iscapable of rotation but is stationary in respect of its axis.
  • the axis of the rod B is vertically below the axis of the roller C and the linkages which carry and apply pressure to the sections'of the bed are pivotally mounted on the rod B so that the rod B and the bearings c for the shaft C of the roller C form stationary supports which receive the load applied to the machine.
  • the bed is formed of two memori of trough like sections D and D one series being on one side of the vertical longitudinal centre line of the machine and the other series on the opposite side thereof.
  • Each section D is formed with a curved surface d corresponding to the cylindrical surface of the roller C and extending over rather more than 90 so that when the sections are in contact with the surface of the roller they embrace rather more than 180 thereof.
  • Each section D is in the form of a steam chest to which steam is supplied by flexible tubing through the inlet d and exhausted through the outlet d 7
  • a series of ribs 1 or other means are cast with the chest to strengthen it.
  • the sections are controlled in pairs, one from the-series D and the other from the series D
  • the section D is pivotally mounted on one end of a link 6 the other end of which is pivotally mounted on the fixed bar B and the section'D is pivotally mounted on one end of a corresponding link e the other end of which is also pivotally mounted on the bar B.
  • Two further links 1 and f are pivotally mounted on the same pivot points on the sections D and D as the links e and e and are connected together by a tie bar F one end of which is pivotally mounted on the link I and the other on the link F, the pivot points being approximately mid-way along the links.
  • the piston rod G and cylinder G are not fixed they are free to move in relation to each other thus when the piston and piston rod G move inwards towards the longitudinal centre of the machine the cylinder G2 will also move inwards toward the said longitudinal centre i. e. in tha opposite direction to th piston and piston ro
  • the consequent movement of the lower ends of the links f and F Will cause the piston rod G and the cylinder G to move inwards towards the longitudinal centre of the machine until the piston has come to the end of its inward stroke when the parts are in the position shown in Fig. 2.
  • each pair .of sections D and 'D? of thebed is supportedas hereinbefore described-by links e and e and'controlled by linksf and f -froma piston G and cylinder G there being as many pistons :and cylinders as there are pairs of sectors and all the cylinders are supplied simultaneously with steam or other pressure fluid at the same pressure so that they will operate-in unison.
  • each pair of sections D and D may be vprovided withintermeshing teeth which when engaging each other leave a small'gapthrough which moisture from the work canbe withdrawn by the application of suction tothe space formed by thetwo recesses d at the lower ends of thesections.
  • roller Cris built up from a'series of sections C pre'ferably,'though not necessarily, equal in number and length to the sections D or "D forming the bed.
  • Each section 0 is .carried'bytwo sets of arms H and H radiating from a hub I-I afiixed on the roller shaft 0 mounted in the bearings c at each end of the machine.
  • the ends of the rollers are closed by end discs C
  • the roller C is heated by longitudinal steam pipes .K carried by hollow spokes k at each end .of the roller, each pipe being ,provided'with an interior helix k which ensures movement of the steam along the pipe as the roller rotates.
  • Each end of the roller shaft c is formed with an axial passage 0 which is connected to the passages in the spokes Ic, steam being supplied at the inlet endIL and exhausted at the other end L
  • the hollow spokes k are preferably made in two parts connected by a union k for ease of assembly and the spokes at the inlet end are each provided with a check valve k :Steam is supplied to the passage 0 at the inlet end in any suitable known way for supplying steam to a hollow rotating shaft and is similarly exhausted from the passage 0 at the exhaust end.
  • the abutting endsof the sections C are pref-- erably for-med with spigot ends as shown .at .0 and the sections are pulled together by nuts h actingon the end hubs H. j
  • the periphery of the roller C is perforated as shown in Fig. 6 and is surrounded by a layerof wire mesh M over which the usual blanket covering is laid.
  • Moisture from the work may thus bedrawn into the roller by the application of suction to its interior such as through the stationary housing N surrounding the shaft C at the end L of the roller and in contact with the end disc C through which apertures are formed.
  • the housing .N is connected by a duct 11, to a suitable exhausting means.
  • the roller C can be driven in any usual way and the feeding and delivering of the work .to and from the roller can also be conventional, the sections D and D being provided with curved extensions 11'' at the feed-and delivery edges.
