Abstract

1,201,904. Bar-stock feeding apparatus. WALTER GOLD & SONS Ltd. 12 Jan., 1968 [20 Jan., 1967], No. 3013/67. Heading B3B. A bar feed device comprises an elongate tube 23 within which is slidably located a feed unit which includes a body portion 10 and a bar receiving portion 18, a spigot 21 on the bar receiving portion being engageable in a socket in the body portion with a ball thrust member 20 therebetween whereby relative rotation between the two portions is permitted as the feed unit moves axially along the tube 23 with the bar 25. The axial movement of the feed unit is effected by air pressure admitted through a nozzle 27 at the closed end of the tube 23 which acts on the body portion which is sealed against the bore of the tube 23 by a resilient frustoconical member 12 attached to a threaded spigot 11 on the body portion 10. The bar is engageable in a socket 22 in the end of the barreceiving portion remote from the body portion 10. It is stated that the feed unit may be actuated hydraulically or mechanically. (For Figure see next page.)
