Abstract

<PICT:0783182/III/1> Articles of flat ceramic ware which have been sprayed on one face while travelling on a conveyer consisting of a plurality of parallel endless wires (not shown) are turned over to present their other faces for spraying by a wheel which consists of a number of slotted discs 20 arranged between the wires, and which is rotated through part of a revolution about an axis transverse to and just above the plane of the wires in response to an article entering one of the slots and contacting the operating lever 39 of a switch 38. Closure of switch 38 by the article energizes a solenoid 37 controlling a valve 36 which thereupon supplies compressed air to the lower end of a cylinder 31, extending its piston rod to move a pawl carrier against the damping action of an oil-filled damping cylinder 34. A pawl 26 on the pawl carrier turns the discs 20 through a ratchet wheel 25 through one sixth of a revolution to brng the next series of slots into position for receiving an article. At the end of the movement an abutment 40 on the piston rod of cylinder 34 operates a switch 41, de-energizing solenoid 37 to re-set valve 36 whereby air is exhausted from the lower end of cylinder 31 and admitted to the upper end to return the parts to their original positions in preparation for the receipt of another article. A spring-loaded catch 28 prevents backlash in the ratchet mechanism. After three such movements the first-received article is deposited back on to the conveyer wires, in inverted position.
