Abstract: 186,482. Bossert, C. P. Aug. 3, 1921. Coating-machines.-In a machine for applying a thick plastic substance to an article, particularly for applying a hair-removing compound such as the sulphides of soda and lime to hides and skins, the substance is applied by an agitating- device to a feed-roll from which it is removed and thrown on to the hide or the like supported on a conveyer. The hide is placed on an endless travelling band 5, Fig. 2, carried by rollers 3, 4 mounted in the frame 2 of the machine, the roller 4 being driven by gearing from a shaft 6. Mounted on the machine frame above the band 5 is a hopper 36 to which the plastic compound is supplied from a tank 46 mounted above the machine. The hopper comprises end members 37 and a body member 38 secured by flanges 40 on end brackets 39 to a housing 42, Figs. 3 and 6. In the hopper is mounted an agitator 30 provided with helical surfaces 31 which contact with the feed-roll 25 to supply it with a film of the substance, the feed-roll and agitator being driven at a comparatively slow speed and in the same direction by gearing from the shaft 6. The agitator is preferably made in cylindrical sections 59, each having the helical members 31 cast thereon and being keyed to the shaft 29. The distributing means comprises a shaft 33 driven at a high velocity in a direction opposite to that of the roll 25, and provided with a number of radially-projecting flexible strips 34 extending the whole length of the roll 25. As the shaft 33 is rotated, the strips 34 contact with the roll and remove therefrom a portion of the substance adhering thereto, the substance being thrown down on to the hide on account of the speed of rotation. A guard or casing 35 may enclose the parts 25, 30, 33. The substance adhering to the band 5 is removed by scrapers 51. Fig. 2, beneath the band, and is received in an inclined trough 50 discharging into a receptacle 43, from which it is pumped back to the tank 46. The band is further cleaned by a spray of water.

Filed: 1957-07-09
Abstract: 840,346. Centrifugal switches. COMPTOMETER CORPORATION. July 9, 1957 [July 11, 1956], No. 21698/57. Class 38 (5). [Also in Group XXVI] A rotary switch governor for an electric motor 11 comprises an insulating disc 17 mounted on the end of motor shaft 12 and having slip-rings 21 and 25 riveted on the back face thereof for making connections to brushes 29c and 28c respectively. Two L-shaped brackets 22, 23 and 26, 27 are secured to the front face of disc 17 by means of rivets which also serve to make respective electrical connections to the sliprings 21 and 25. The bracket arm 22 carries a cantilever spring strip 32 having a contact 29 on its free end normally engaging a fixed contact 28 on bracket arm 26. The spring strip 32 is slightly off-centre with respect to the shaft 12 such that when rotated centrifugal force tends to hold the contacts 28, 29 closed. A rigid lever 35 having a U-shaped cross-section, and of greater mass than spring strip 32 and contact 29, is pivoted on the disc 17 by pin 37 to lie substantially parallel to strip 32 but on the opposite side of and at a greater distance from, the axis of shaft 12. The lever 35 is biased by a hairpin spring 41 having one arm supported by an adjustable stop-screw 50 in a locking mounting fixed on disc 17. An insulating block 38 carried on lever 35 bears on strip 32 in alignment with contacts 28, 29 and further assists in maintaining these contacts closed when the motor is at rest. The free end of lever 35 extends beyond the end of strip 32 and terminates in a hook portion 40 as shown. As the motor speeds up the lever 35 moves outwardly but the contacts 28, 29 are maintained closed by centrifugal force until the hook 40 engages the end of strip 32. On further increase in speed the greater centrifugal force acting on lever 37, due to its greater mass and greater distance from the axis of rotation, overcomes the forces tending to close the contacts 28, 29 and these are thereby opened, the speed at which this occurs being preset by means of screw 50.
