Apparatus for transferring articles such as glass containers (A) from a first conveyor (3), on which the containers (A) are travelling generally horizontally in line one after another, on to a second conveyor (5) extending generally at right angles to the first conveyor (3) from one side of the first conveyor (3). The apparatus is operable in cycles to transfer on each cycle a group of articles (A) from the first conveyor (3) to the second conveyor (5) with the articles in the group extending in a row transversely of the second conveyor (5). The apparatus includes a support (13), a first carriage (15) on the support (13) movable generally parallel to the second conveyor (5), a second carriage (17) on the first carriage (15) movable with respect to the first carriage (15) generally parallel to the first conveyor (3), and a third carriage (19) on the second carriage (17) movable vertically with respect to the first and second carriages. The third carriage (19) carries a pusher bar (125). The carriages are driven by separate motors (43,81,117) under the control of a programmable controller (51) which operates the motors (43,81,117) during each cycle of the machine to drive the carriages (15,17,19) to cause the pusher bar (125) to transfer a group of articles (A) from the first conveyor (3) on to the second conveyor (5).
