Claim 1
Independent Claim
90 words
In an electrically operated dispensing machine in which actuation is initiated by pulling a handle, the improvement of a device for simulating mechanical actuation comprising: a ratchet member having a surface comprising a plurality of alternating ridges and notches; a member for engaging said ratchet member surface comprising a pivotally mounted arm having a protuberance thereon for progressively engaging said ratchet member surface; said ratchet member being secured for movement to engage said engaging member whereby said protuberance is urged along said ratchet member surface when said handle is pulled.
