Abstract

952,974. Bar feeds. HARDINGE BROTHERS Inc. Oct. 23, 1962, No. 40042/62. Heading B3B. A bar stock feeding device comprises an outer tube 12, an inner tube 14 concentrically mounted with an annular space therebetween and a piston 30 adapted to be reciprocated within the inner tube. The free end of the tube 12 is sealed by a screwed plug 15 which also supports the inner tube 14. The discharge end of the tube 12 houses a sleeve 18 which receives a split bushing 20 to support the bar stock 11 during machining. Fluid means such as compressed air is supplied to the piston and cylinder assembly through ports 61 and 63 to actuate the piston 30 to feed the bar stock into the machine. The device is supported by stands 24, 25 which are adjustable in height. The stand 25 has means for securing the device in the form of a clamping screw which also co-operates, when clamping or releasing, with a valve head 46 which permits the opening or closing of the pressure system when the device is removed and installed during renewing of the bar stock.
