Be i known that'I, Annnm M.

A is the hopper of a ba filling machine into which material to be ed into: the'bags designated by 'like characis introduced.

Y

C'is an'A-frame guided at its upperend by a check bar C which is pivoted at C2, in a housing C, to compensate for vertical movement of the A-frame. 'This housing C7 is ladjustable in and out .'by" means of the set screw vC$4 and is' held in position by 'means of the setecrew C.

Y XN? I "tionthe fabric of the bag will be engaged by ,top ofthe'bag is"mo.vedso that the dis-- charge nozzle extendsjinto it. In this posithe holding Qmechanism described. As the 3,0 bag is filled itgradually depresses the. scale beam and when'it is completely 'filled the discharge of material into it is stopped. The hook or stop member E prevents the outward. lmovement of the cradle until the material in the bag moves the scale beam upon which the cradle is niounted in afman-` ner more fully. described in my priorPatent 1,209,105, 'granted December; 19, '19.16.'

The-Lhandle controlling the'cradle is then moved outwardly and upwardly bythe' op'- erator. [The bag-'is thereby automatically released from' the nozzleandV is tipped Y forA -ward and out of-the frame; The handle which `controls the' cradle is, as above described, supportedfffrom above, and. its 1 `s veight is notA supported by the-scale beam and thus any" weight from the' hand of. theoperator` `upon tins vcontrolling handle does not come upon'the scale beam so' asto upset.
