Abstract
Abstract Bar feeder apparatus for separating one bar at a time from a supply of bars so that the bars can be individually delivered to a bar working machine upon demand. The apparatus includes a rotatable transfer drum which picks up one bar at a time from the supply and delivers it to a downwardly inclined rack, the pick-up means of the drum being adjustable to enable it to accept bars of different diameters. At the lower end of the rack means are provided to retain the bars in a row on the rack, the retainer means also being adjustable for bars of different diameters. Cooperating with the retainer means is an actuator mechanism for releasing one bar at a time from the rack for delivery to the bar working machine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
211 words
In a bar feeder apparatus, a rotatable bar transfer drum for separating one bar at a time from a supply of bars as the drum rotates, the drum comprising a drive shaft, a plurality of uniformly spaced pairs of discs mounted on the shaft, one disc in each pair being fixed on the shaft and the other being angularly movable relative thereto, each disc in the disc pairs being formed with a plurality of bar receiving cavities spaced uniformly about its periphery, the two discs in each pair being angularly movable relative to one another to bring their respective cavities into a predetermined degree of registry for receiving a bar of a given diameter, a plurality of elongated tie rods passing through all of the discs together with means to tighten the rods so that the discs are maintained in fixed relation to one another after the cavity adjustment has been made, the tie rods passing through closely fitting holes in the movable discs and through slots in the fixed discs, and means connected to the drive shaft and operable before the tie rods have been tightened to vary the angular position of the shaft whereby the angular position of the fixed discs relative to the movable discs can be adjusted.

Claim 3
Dependent Claim
182 words
In a bar feeder apparatus, including an inclined rack comprising a plurality of spaced, parallel plates, a bar retainer assembly located adjacent thE lower end of the rack and comprising a plurality of retainer levers disposed between adjacent pairs of plates and projecting above the upper surfaces thereof, the levers being fixed on a common shaft journalled for angular movement whereby the height of the levers above the rack plates can be adjusted, a plurality of operator levers respectively positioned adjacent the retainer levers and normally disposed below the upper surfaces of the rack plates, the operator levers being fixed on a second common shaft, means to rock the last-named shaft and rotate the operator levers whereby a bar resting against the retainer levers is pushed over the latter and can leave the rack, a lever arm operably connected to an end of said first-named common shaft, a scale coacting with said lever arm, and means to secure the arm in any desired position with respect to the scale to set the retainer levers at the desired height above the rack plates.
