Abstract

642,746. Inking and damping apparatus. HOE & CRABTREE, Ltd., R. Aug. 8, 1947, No. 22124. Convention date, June 28, 1941. [Class 100 (ii)] An inking or damping apparatus comprises a fountain, a fountain roller, means for continuously rotating the fountain roller, a braking device to control the speed of rotation of the fountain roller and means to render the braking device effective if the fountain roller rotates faster than it is being driven. The fountain roller 18 is driven by a shaft 55 connected to a shaft 45 through a flexible coupling, the shaft 45 being driven by a shaft 36 driven by an electric motor 32 through a variable speed gear 33. The shaft 36 carries a threaded sleeve 37 which engages a nut 44 fixed to the shaft 45. A flange 64 is keyed to the shaft 45 and is provided with a brake face 66 which can engage an annular brake face 67 secured to the frame 47. When the speed of the roller 18 increases above the speed at which it is driven by the motor 32 due to engagement with a ductor roll (not shown) rotating at a high speed the nut 44 is screwed further on the sleeve 37, thus causing the brake face 66 to engage the face 67 and so decrease the speed of the roller 18. When the speed of the roller falls below normal the nut 44 is unscrewed to separate the faces 66 and 67.
