Abstract

1,226,413. Metal stock feed. A. W. SCRIBNER. 12 June, 1968 [23 June, 1967], No. 27854/68. Heading B3W. [Also in Divisions B8 and F2] In a machine such as a press stock is fed by feed heads 24, 53 reciprocated by fluid motors 17, 47, the heads carry stock-gripping means 32, 60 operated by separate fluid motors and a control means operates so that each feed head in turn partakes of a feed stroke while the other partakes of an indexing stroke, the feeding strokes being initiated when the press or like tool is nearer to the bottom than to the top of its operative stroke. The feed heads may be side-by-side as shown in Fig. 1, or in end-toend relation moving alternately toward and away from each other, Fig. 10 (not shown). Stroke adjustment is by a collar 74 positioned over holes 75 or 76, a fine adjustment is provided by an abutment 73 threaded on collar 74. The control means is a cam-operated valve (F2V), the cam being operated by the ram of the press so that it completes one cycle for every two cycles of the press ram.
