Abstract: 629,088. Towelling dispensers. STEVENS, A. H. (Steiner Sales Co.). Oct. 12, 1945, No. 26671. [Class 18] A device for dispensing towelling that is drawn from a supply roll and subsequently rewound on another roll, has means for limiting immediate supplies to three lengths or bights and means for restoring delivery only after the lapse of a predetermined interval. The device comprises two upright plates 2, 3, between which are supported a pinch roll 32, and a soiled towelling roll, the latter being driven by frictional contact with a roller 17 connected by chain and sprocket gearing with a measuring roll 16 in surface contact with the pinch roll. A disc, secured to the end of the roll 17, has a protruding portion 46 with a shoulder 47 that engages a shoulder 51 formed on the lower end of a pivoted arm 49. On rotation of the roll 17, by the user pulling on the towelling, the protruding portion 46 strikes the upper part of the arm 49 and throws the lower portion into the path of the protruding portion 46 of the disc so that the shoulders 47, 51, become engaged and a further delivery of towelling is momentarily stopped. On release of the pull on the towelling, the shoulders become disengaged and the arm 49 drops to an inoperative position so that a further delivery may be obtained. A link 97 eccentrically mounted on the end of the roll 17, is connected to a slide 93 having a pawl 96 and an arm 104. Rotation of the roll 17 causes the link 97 to raise the slide 93 so that the pawl engages the top ratchet of an upper set 94 on a second slide 92, arranged parallel to the first slide 93, causing it to be raised. At the same time the arm 104 engages a rod 102 to raise it clear of an arm 108 of a second pawl 106 and to allow this pawl to fall to a position where it will engage the top ratchet of a lower set 95 formed on the second slide 92, the rod 102 being held in a raised position by a suction cup 101 thereon engaging a stationary cup 100. One complete revolution of the roll 17 causes the pawl 96 to raise the second slide 92 to a position where it is held by the second pawl 106 as the first pawl 96 becomes disengaged by the completion of rotation of the roll. Further rotation of the roll causes the first pawl 96 to engage a second ratchet of the top set 94 and to raise the second slide 92 to a higher position in which it is similarly held by the second pawl engaging another ratchet in the lower set. Still further rotation of the roll 17 causes the first pawl 96 to engage the bottom ratchet in the top set and to raise the second slide such that it engages a rod 80 carrying an arm 85 which holds the pivoted arm 49 in a position causing the shoulders 47, 51 to become engaged to prevent further withdrawal of towelling. The rod 80 and arm 85 are maintained in this position by a suction cup 79 on the end of the rod adhering to a stationary cup 75. An air inlet hole 76 restricts the passage of air between the cups 75, 79, and 100, 101, so that a predetermined period of time passes before the rods 80, 102 drop to their original positions to permit further withdrawal of the towelling. The first slide 93 returns to its initial position at the end of each revolution of the roll 17 and therefore when the lower rod 102 falls and disengages the second pawl 106 prior to the lowering of the upper rod 80 it in no way obstructs the return of the second slide 92 to its initial position.
