  • Fig. 8 is a view similar to Fig. 5, showing the release mechanism at the extreme point of roll release travel.
  • the illustrative ernbodirnent comprises an ironing machine which, except for the improved emergency roll release mechanism described hereinafter, is described in detail in my aforementioned copending application.
  • the ironing machine generally comprises an ironing shoe 10 and an ironing roll 12, suitably mounted on a base 14, which is provided with legs as 16.
  • the roll 12 is rotatably supported on a pair of spaced arms 18 and 20, as by the shafts 22 and 24 which are carried in suitable bearings as 26 and 28.
  • the roll 12 is adapted to be rotated by ice means of the electric motor 30 acting through a driving means comprising, the gear train 32, clutch mechanism 34, gear train 36, shaft 38 and gear train 40.
  • the motor 30 is also adapted to swing the roll 12 towards the shoe 10 into a working engagement therewith, by means of the gear train 32, clutch mechanism 42, the eccentric mechanism 44 and the lever 46, which is fixed in the pressure sleeve 48.
  • the roll supporting arms 18 and 20 are joined by a longitudinal tube 50 in which is oscillatably mounted the pressure sleeve 48.
  • the rear side of the longitudinal tube 50 is ⁇ provided with a circumferential aperture 52 through which the lever 46 passes, so as to permit it to be fixed in the pressure sleeve 48, as indicated at 53.
  • the circumferential aperture 52 is formed to permit a substantial movement of the lever 46 relative to the tube 50.
  • the pressure sleeve 48 is adapted to be releasably tiXed to the tube 50 by means of the release mechanism generally designated 54.
  • the tube 50 is provided with a longitudinal aperture 56, on the front side thereof, which is disposed adjacent to the left end of the pressure sleeve 48.
  • the left end of the pressure sleeve 48 is formed to provide a hollow structure 57.
  • the front side of the pressure sleeve 48 is provided with a longitudinal aperture 58 in which is freely carried a lock pin 60.
  • a spool 62 which is provided with two end portions 64 and 66 adapted to seat on the inner surface of the sleeve 48.
  • the spool 62 is provided with a center portion 68, having a diameter smaller than the end portions 64 and 66 and on which is oscillatably mounted a release trigger 70.
  • the release trigger 70 is substantially arcuate in cross-section and extends longitudinally of the spool 62, abutting against the spool end portions 64 and 66.
  • the release trigger 70 is provided with a longitudinally disposed, inwardly slanting portion 74, on the front side thereof, which is adapted to cam the lock pin 60 outwardly into a locking engagement with the aperture 56 in the longitudinal tube 50, whereby the pressure sleeve 48 and the tube 50 are releasably locked against relative movement.
  • the aperture 56 is provided with a tapered inner edge, as designated at 75, which is adapted to form a seat for the reception of lock pin 60.
  • the rear side of the release trigger 70 engages a longitudinally extending portion 76 of the torsion spring 78, which is adapted to resiliently bias the release trigger into a locking engagement with the lock pin 60 and the aperture 56.
  • the torsion spring 78 is disposed on the left end of the spool 62 and has one end anchored in the pressure sleeve 48 at a point as designated by the numeral 80.
  • the left end portion 64 of the spool 62 is cut away along a portion of its circumference, between the points designated 81 and 83, to permit the longitudinal portion 76 of the torsion spring 78 to engage the release trigger 7l).
  • a plurality of ⁇ coplanar and adjacently disposed arcuate apertures 82, 84 and 86 are respectively provided in the longitudinal tube 50, the pressure sleeve 48 and the release trigger 70 which are adapted to permit the passage therethrough of a release handle 88 which is ⁇ fixedly secured in the spool 62 in the aperture 90, ⁇ as by the threads 92.
  • Thisv is the. position in which the release mechanism, 54 is disposed during normal operation' of theironing machine.
  • the roll 12 may be oscillated by4 means ofthe eccentric mechanism 44, which provides approximately a one-half' to three-.quarters Vof .an inch separation between the rollV 12v and theshoev 10.
  • Such. amount otV separation is well adapted rfor ordinary ironing andlpressing use, but in case of anV emergencyy a much wider separationbetween the roll and the shoe is ⁇ desired. ⁇ A novel feature of the present invention.
  • thean'ormal operating position for the release handle 88 is approximately lifteen degrees froml the vertical. plane,y towards the rear side lof the machine.
  • theV operator may manually release the roll frorrrt-he shoe y by, exerting ⁇ a, rearwardly directed forceon. theV release handle 88, so as to rotate the handle approximately 45f The releasing action during such movement of the release handle 88.- may be understoodbyv considering Figs; 5 through 8.
  • the operator may restore the; ironing roll-..112 to itspre release relationship4 with-,the normal roll. voscillating,meehis. associated the eccentric:4 mechanism 44.
  • the* torsion'A spring arm 76 -resiliently biases the release trigger back to the initial locking position shown in Fig. 5.
  • the return movement of release trigger 70 is effected by torsion spring 78, its actual rate of return movement is governed by the return movement of release handle 88.
  • Such4 action occurs because the rear end 94 of the release trigger slot86 is urged by spring 78 into engagement with the release handle 88 during the return movement, thereby permitting the release trigger 70 to be moved only when the release handle is moved.
