Abstract
An apparatus for dispensing measured lengths of a sleeve material upon an armature, especially adapted for dispensing a plastic cover upon a toilet seat, includes a source of sleeve material fed onto the armature and collected upon a take-up reel. The cover is provided with a uniform series of marks along its length which are sensed and counted to control the operation of a motor drive which directs the sleeve material to and from the armature. Timer circuits are employed to cause motor cut-off if the required length of sleeve is not dispensed within a given length of time and to inhibit motor start for a fixed period after a dispensation. The sleeve-accepting end of the armature may include an angular horn to permit the sleeve to smoothly pass onto the seat.
Claims18
Apparatus for dispensing predetermined lengths of a continuous tubular material about the length of an armature having first and second ends, comprising
- a tubular material source located proximate said first end and a tubular material collector located proximate said second end;
- guide means mounted to said first end to direct said tubular material onto and about said armature at said first end;
- drive means coupled to said collector to pull said tubular material along said armature from said source onto said collector;
- means affixed to said tubular material at fixed intervals therealong to mark continuous lengths thereof;
- sensor means located proximate said second end to generate a count signal upon the passage of each of said marking means thereby;
- and control means operatively connected to said sensor and drive means to activate said drive means upon receipt of a start signal for a period of time associated with a predetermined number of said count signals being received from said sensor means, whereby a predetermined length of said tubular material passes from said source onto said armature, a corresponding length of tubular material previously upon said armature being collected by said collector.
Apparatus for supplying a cover on a toilet seat comprising:
- a toilet seat in a generally ring-like configuration having first and second ends;
- a cover supply and takeup assembly comprising a cover source comprising a continuous length of tubular cover material having a plurality of marks thereon dividing the length thereof into equal segments located proximate said first end for supplying fresh cover material to be arranged along the length of the seat and about its surface and a cover collector located proximate said second end for the take-up of used cover material from the seat;
- drive means operatively connected to said cover supply and takeup assembly for dispensing fresh cover material onto said seat and used cover material into said collector;
- sensor means for sensing the passage of each of said marks past a fixed point along said seat and generating a sensor signal in response thereto;
- and
- control means connected to said sensor and drive means for operating said drive means in response to a start signal for a period associated with a count of the signals generated by said sensor means to provide fresh cover material along the length of the seat.
