Abstract
733,398. Sheet-delivery apparatus. GESTETNER, Ltd. April 27, 1954 [Sept. 4, 1953], No. 24529/53. Class 100 (1). A duplicating machine comprises a rotatably driven stencil-carrying cylinder, a pressure roller to apply the copies to the cylinder and blades for stripping the copies from the cylinder, the pressure roller and the blades being movable towards and away from the cylinder, and the blades being so moved by a mechanism separate from that which moves the pressure roller. Sheets are fed between the lower cylinder 12, Figs. 2 and 5, of a stencil duplicating machine and an impression roller 13, and are stripped from the cylinder by two blades 28, whence they are passed to guides 23 and thence to a stack. In order to permit the free passing of the means for attaching the stencil and screen to the travelling band 14, the roller 13 and the stripper blades 28 are oscillated towards and away from the cylinder 12. The blades are secured to blocks 29 which are adjustably secured by means of nuts 30 along a bar 25 so that the blades can be set to engage the parts of the sheets having least ink. The bar 25 is mounted at one end in a spring bearing to facilitate removal. The machine is driven by a handle 16 on a shaft 17, and the latter carries a cam 36 which acts on a lever 38 to oscillate a rocking member 34 pivoted at 35. A slot 33 in the member 34 engages a pin 32 on a lever 31 secured to the bar 25, so that the blades 28 are oscillated. The blades 28, the ends of which are bevelled to be tangential to the cylinder, are not required to touch the cylinder, and the size of the gap is adjusted by means of a cam 55 engaging the pin 32, the cam being set so as to correctly limit the upward stroke of the blades. The guides 23 are part of a member 20 which is hooked on to a bar 19 and secured by a spring clip 21 engaging a spindle 22. The top edge 24 of the guides is central of the sheets and higher than the blades 28, so that the sheets are bowed in the centre to impart a certain rigidity thereto.
