Apparatus for dispensing sheet material
First Claim
1. Apparatus for dispensing sheet material comprising:
- structure forming a housing having a discharge opening;
means disposed within the housing for storing a supply of sheet material with a portion of the sheet material positioned within the housing adjacent the discharge opening;
advancing means disposed within the housing for advancing the sheet material through the discharge opening, said advancing means including an electric motor;
means for activating the advancing means for a predetermined period of time to advance a predetermined length of the sheet material through the discharge opening, said predetermined length of sheet material being grippable by a user to enable the user to withdraw a length of the sheet material from the dispensing apparatus;
means for enabling the activating means for permitting the activating means to supply electrical energy to the advancing means;
said enabling means and said activating means being associated with the housing and being responsive to the proximity of a portion of a hand of a user with respect to the housing without the user contacting the dispensing apparatus for enabling the activating means and thereafter activating the advancing means for advancing a predetermined length of the sheet material through the discharge opening; and
means responsive to the withdrawal of sheet material by the user for storing energy to energize said electrical motor.

Abstract
The disclosure relates to an apparatus for dispensing sheet material such as paper towels. The dispensing apparatus when activated dispenses sheet material for a predetermined time which results in a predetermined length of sheet material being dispensed. The dispensing apparatus is actuated in response to the proximity of a portion of a hand of a user to the dispensing apparatus without the hand of a user contacting the apparatus. The dispensing apparatus dispenses sheet material from a roll of material by means of an electrical motor operating for a predetermined time to advance a predetermined length of the sheet material. The motor for advancing a predetermined length of the sheet material can be battery powered. The housing of the dispensing apparatus has a modular frame having a first compartment for the means for advancing the sheet material and a second compartment for the means for activating the advancing means. The dispensing apparatus can include means for storing energy for energizing the advancing means in response to the withdrawal of sheet material from the dispensing apparatus by a user.
