Definitions

  • Laundry ironing machines are ordinarily provided with means for varying the pressure exerted by the clothed roller and its polishing bed on one another, reference being had, inter alia,
  • the ends ofthe roller are adapted to yield through different distances, so that the roller may temporarily get out of parallelism with its bed, whereby the cloth of the roller is likely to shift, the consequence being that the thickness of the cloth at one end exceeds that at the opposite end, so that the roller assumes a permanent inclination relative to its bed and the satisfactory operation of the machine is impaired.
  • the means under review ordinarily also serve for lifting the roller from its bed, although this function could as well be performed by a separate lifting gear.
  • the present invention which has for its object to avoid the inconvenience referred to above, is suitable for laundry ironing machines of any description, wherein the bearings of the roller trunnions are associated, through a suitable lever system, with mechanism for lifting and lowering the roller, and it primarily consists herein that all elements of the lever system are rigid and that the said resilient element is interposed in the actuating mechanism. Owing thereto, it is impossible for one end of the roller to move up or down and thereby increase or decrease the tension of the resilient element, withoutthe'other end performing an equal movement, abstracting, of course, from possible slight clearances and torsions in the various parts of the pressure controlling means.
  • FIG. 1 and 2 illustrate an elevation and an end view, respectively, of a preferred embodiment of the invention
  • Fig. 3 being an end view of part of a second embodiment.
  • the clothed roller is designated by 4, the stationary, heated polishing bed by 5.
  • Each of the bearings 6 and I of the roller trunnions is pivoted to the top end of a crank rod 8, 9 respectively, the lower end of which is asso- 10 which is pivoted to the frame.
  • crank I II I I
  • shaft I2 which extends in parallel relation with the roller axis and is supported vertically below the roller in bearings of the frame of the machine.
  • the crank rods are of equal lengths, and the same is the case with the two cranks, which, moreover, are parallel with one another.
  • Each bearing 6, 1 is associated with one end of a normally horizontal arm I3, the other end of The drawing shows only one of said arms, which are parallel and of equal lengths.
  • crank shaft I2 causes the roller to perform movement, in parallel relation with itself, in a circular path about the stationary common axis of rotation of the arms I3.
  • the roller 4 is lifted from, or urged towards its bed '5.
  • a segment of a worm wheel I 4 is keyed thereto, said segment meshing with a worm I6 keyed to a horizontal, transverse shaft I5.
  • Said transverse shaft which is provided with a handwheel I50, and is lengthwise movable in bearing blocks I 1, It secured to the frame, is also provided with a collar I9 adapted to abut against the bearing block I8.
  • a coiled spring 26 Interposed between, and bearing against both worm I6 and bearing block I! is a coiled spring 26 encircling shaft I5.
  • Bearing I8 is provided with a scale 2
  • the roller l4 will first descend until original conditions are restored, whereupon worm F6, in conjunction with the transverse shaft I5, is gradually moved to the left so as to load spring 26.
  • the pressure of loaded spring 20 is transmitted, as an additional ironing pressure in excess of the weight of the roller, to the latter through the medium of worm I6, segment I l, shaft I2, cranks I0, II and Said additional ironing pressure can 3 be read from scale 2
  • the pressure exerted by theroller on its bed rather sud: denly increases,- from zero to a maximum value,- from the moment wherein the descending roller engages its bed, so that accurate adjustment Off said pressure is difficult to realize.
