Title: Improvements in apparatus for coating the interiors of barrels, drums, cans and the like
IPC: B05B3/06
Filed: 1929-04-15
Abstract: 330,060. Downs, J., and Watts, Fincham, & Co., Ltd. April 15, 1929. Gearing for stopping and starting machinery.- In apparatus for coating the interiors of barrels, 'drums, cams &c. which comprises an air ejector and valves to control the supply of air and composition to the ejector, arrangements to control the valves semi-automatically involve a clutch mechanism. The operation is as follows :-The barrel &c. is positioned with the nozzle 12 dependent therein. Lever 28 is manually depressed and a cam 63 on the lever 28 contacts with a roller 56. As a consequence arms 50 are turned about their pivotal mounting 52, springs 57 first opposing and then assisting such movement. A muff 48 is thereby moved to the right and held in such position by the springs 57 acting on the arms 50. The movement of the arms 50 also moves the free end of an arm 62 into the path of a roller 64, through the agency of a Y-shaped member 60 and its spindle 61. As the muff 48 moves to the right, it passes between two bellcrank levers 47 and turns them about their pivotal bearings in arms 46. The levers 47 are in engagement with a fixed collar 42 and their movement under the action of the muff 48 is possible only by movement of a collar 45 which, together with a sleeve 35, moves endwise on a constantly driven shaft 34 and brings a male clutch member 40 into engagement with the other clutch member 39. When the clutch is engaged, a disc 37 is coupled to the shaft 34 and rotated thereby. The disc 37 carries the roller 64 and a weight 68. As the disc 37 rotates, the roller 64 contacts with the arm 62 which is turned counter-clockwise. The movement, through the spindle 61 and Y- shaped member 60, actuates the arms 50 and moves the lower end of them and the muff 48 to the left. The movement of the muff frees the bell-crank levers 47 and allows springs 41 to move the clutch faces apart and also to move the sleeve 35 and collar 45 endwise along the shaft 34. The disc 37, being free of the drive from shaft 34, resumes its starting position by the action of the weight 68.
