MACHINE FOR rnnnmo' nnannn BLANKS. Application filed September 6, 1923. Serial No. (31,210.

This invention relates to machines for aurim of the bucket wheel 21 and is provided 55 tomatically feeding headed blanks with their with a flat rear section parallel to the plane headed ends upward, and more particularly to of the bucket wheel. Each bucket 27 is roi a blank feeding machine inwhich a series of vided at its forward end with a laterally ina blanks are continuously fed upon an inclined clined end wall adapted to deflect blanks to chute from a rotary bucket Wheel, which is Ward the front of the bucket wheel. The 60 mounted to rotate in a plane at right angles to. 1 buckets 27 are adapted to pick up blanks from the ch t the hopper while the buckets are traveling One object of the invention is to provide a upwardly, and to discharge the blanks into 10 device of the above nature which will be simthe chute 19 when traveling downwardly.

In order as vided with a peripheral flange 20 against to prevent the properly positioned blanks which a rotary blank feeding bucket'wheel 21 which pass under the kicker wheel from beis adapted to fit. The bucket wheel 21 is ing accidently jolted out of the chute by the mounted on a stud shaft 22 supported by a vi ration of the machine, a cover rail 44 is bearing standard 23. The standard 23 has 11 provided, said cover rail being secured to said 100 flat front section 24 secured to the base 13 by chute by angle brackets .45 and screws 46. bolts 25. The rear end of the shaft 22 beyond One advantage of the present invention lies the standard 23 is provided with a hand wheel in the fact that the bucket wheel is located at 26 by means of which the bucket wheel 21 may the end of the chute and at right angles therebe manually rotated whenever desired.
