  • the oscillating motion of a shaft 66 is for the purpose of actuating the heated metallic shoe 8 of the ironing machine into and out of contact with the under side of the roll I8 (see Figures 2 and 3) through a system of links and levers which will now be described. It is assumed for the purpose of this description that the shaft 66 is oscillated at the will of the operator by mechanism and controls later to be described and also that the roll I8 is rotated in a counter-clockwise direction as viewed in Figure 1.

  • the members 92 are directly connected to the end of lever 86 the connected position of the latch member 86 will cause the oscillation of the shaft 66 to move the ironing shoe 8 upward and downward into and out of operative position with the roll I8.
  • An arcuate spring is mounted at its lower end upon a pin 95 carried by lugs 92 depending from the links 92.
  • the upper endof the spring 95 is received in a recess 96 formed in the latch member 96.

  • the flange 84 provided on the hub of the sprocket 26 is engageable by a shifter fork 86, which is pivotally mounted on a bracket 31 by a pin 81.
  • bracket 31 is fastened to a stationary part 31 of the casting l2 by screws 81.
  • the shifter fork 86 When the shifter fork 86 is actuated it will push in opposition to the flange 84 against the action of the spring 86 and disengage and/or hold the lugs 82 out of engagement with the clutch member 26 so that the rota tion of the sprocket wheel 28 will be interrupted. This action of the shifter fork 86 is rendered. in

  • the cam 22 is jecting end 42A in the connected position with clutch member 26, as shown in Figure 10, for rotating cam 22 as previously mentioned.
  • a projecting portion 44 of the member 42 is used to actuate said member to pull it out from rotating engagement with member 26 against its normal spring action.
  • This movement is effected by contact with a cam lever 46 of substantially halfmoon shape ( Figures '7, 8, 12 and 13).
  • Cam lever 46 is mounted upon a pivot 48 secured to a boss 48 in the casting I2 and one of its ends 58 is adapted to be moved clockwise by a solenoid 5 2 6 through a link 58, and to be moved counter clockwise by a torsion spring 48A.
  • Counter-clockwise movement of the cam lever 46 is limited by an adjustable stop screw 46 mounted in a lug 41 carried by the cam lever 46 and engageable with a wall of the casting l2.
  • the projecting portion 44 is engaged with the cam lever 46 and the projection 42A of the clutch member 42 is held up and away from operative contact with the clutch member 26 and, therefore, will not be in a position to cause any rotation of the cam 22.
  • the end 58 of the cam lever 46 will be pulled away from the projection 44 ( Figure 8) and the lever 42 will be allowed by its natural curvature and the action of springs MA and 48A to swing into the position shown in Fig-. ure 10, that is, into a position with the projection 42A engaged in one of the notches 26 in the member 26.
  • return spring 58 is connected at one end by a pin 58 to the cam 22 and its opposite end is connected to a pin extension 68 of the pivot 48.

  • the cam 22 acts against a cam follower 62 and actuates a lever comprising two spaced members 64. and it will be evident on inspection of Figure 6 that the rotation of the cam 22 will oscillate the lever 64 and therefore osc llate the shaft 66 for shoe actuation as previously mentioned, the position of the parts in Figure '11 corresponding to the ironing position of the shoe 8 shown in Figure 2.
  • the lever64 and the shaft 66 can also be seen in the general view of Figure 1.
