Gauge For Controlling Record Advance

The increment of distance through which a record member is advanced is accurately controlled by using an incrementer tape having a fixed limit of travel.

Record member 1 such as a paper tape and incrementer tape 2are inserted between continuously moving bands 3a and 3b. Each is driven about an idler pulley 4 by respective driving pulleys 5a and 5b. Tape 2 is secured by strong spring 6 at one end and weaker spring 7 at the other end. Anchor block 8 is fixed to tape 2 at its one end between two rigid stop members 9 and 10, one of which is adjustable for the desired size of increment.

Member 1 and tape 2 are advanced by energizing solenoid 11. This urges drive shoe 12 downwardly against band 3a to compress member 1, tape 2 and band 3b against brake shoe 13. Such also moves downwardly against fixed stop 14 overcoming spring 15. When brake shoe 13 bottoms, bands 3a and 3b carry both member 1 and tape 2 in their direction of travel until anchor block 8 engages stop 10. The upper surface of tape 2 is coated with a material having a higher coefficient of friction than band 3a so that the record member does not move relative to the tape.

Upon de-energization of solenoid 11, drive shoe 12 moves upwardly releasing the record member and tape. Thus, brake shoe 13 pinches member 1 against fixed element 17. Spring 6 overcomes spring 7 to return tape 2 to its original position with anchor block 8 against stop 9. The energizing signal for sole...
