It'will be seen from Fig. 1 that the arm 38' is journaled'on shaft 39' between the plates 1 [52 which, though fixed to prevent theirrotationgare' adjustable towards each other by means of the nut'54t holding them together soas to causeasuitable drag or friction upon the arm 38Hwhich tends'to retard the move 7 ment of the'ram 28 in the upward and downaward movements; of the ram 30', the purpose: of which will presently appearfi The rock.

The band feeding mechanism shown the; drawings is adapted to feed the bands from a stack of the same contained in a reservoirin which the bands gravitate andre'st upon the inturned shelves 71 at the bottom of the reservoir. The reservoir is suitably held in a fixed but adjustablepositio-n. The top of the stack of bands is pressed upon'by means of two weights'73 which bear upon the stack and force the stack downwardly and against the inturned shelves 71. 'One --ed-ge 0f the needle or pricker 7-4 adjustably held in a bracket aflixed to the reservoir. This pricker'74 by reason of the weight 73 overlymg the pri'cker 74 and also the weight of the stack .of bands in the reservoir .perforates two or perhaps three ofthe lowermost bands in the stack. By this means the lowermost band :can be pushed fromthe bottom of the stack so ithatit can be separated from the same i by the pincers hereinafter described without displacing "the adjacent overlying band.v Tflie separation of the lowermost'band from the stack .isaccomplished by means o-f'a pair ofx-friction' members-or fingers .7 6, pref-v erably made ofzrubber, the reciprocatinggmomost bandbyltearing it away from theirn'paling pricker.
