摘要： A dispensing cabinet for strip material, such as paper towel, has a relatively large handwheel extending through a slot in the front face. A roll of the material is engaged by a boss member on the wheel so as to be rotated by rotation of the handwheel. The edge of the handwheel is provided with radially-extending protrusions constituting both finger engaging members to help the user rotate the handwheel and ratchet teeth engageable by a ratchet member mounted on a pivoted plate mounted adjacent the horizontal cabinet slot through which the strip is dispensed. The ratchet member is normally clear of the ratchet teeth, but any attempt to pull the strip from the roll engages the ratchet member with a tooth so that the roll cannot rotate; the strip can therefore only be dispensed by operation of the handwheel, reducing the tendency to dispense a wastefully long strip. The dispensed portion is torn from the remainder of the roll by pulling it strongly against the lower edge of the plate, which also engages the ratchet so that the roll cannot rotate during the tearing operation.

摘要翻译： 用于条带材料的分配机构（例如纸巾）具有延伸穿过前表面中的槽的相对较大的手轮。 一卷材料通过车轮上的凸台构件接合，以便通过手轮的旋转而旋转。 手轮的边缘设置有构成两个手指接合构件的径向延伸的突起，以帮助使用者旋转手轮和棘轮齿，该棘轮可安装在邻近水平机箱狭槽安装的枢转板上的棘轮构件，通过该棘爪构件分配带。 棘轮构件通常是从棘轮齿上清除的，但是任何从辊中拉出带的尝试都是用齿与棘轮构件接合，使得辊不能旋转; 因此，只能通过手轮的操作来分配带材，从而减少分配浪费长的条带的倾向。 将分配的部分从辊的其余部分撕开，将其强力地靠在板的下边缘上，该下边缘也接合棘轮，使得在撕裂操作期间辊不能旋转。
