Abstract: 328,297. Miller, H. C., and Dainton, E. H. Jan. 23, 1929. Roller-and-sheet recording- apparatus.-Relates to timedistance recorders of the kind having a time-registering device driven by a clock, a mileage or other registering device operated by the vehicle or machine for registering output independently of the timeregister, and an intermittently driven recording apparatus adapted to make a simultaneous record of time and mileage, and consists in operating the recording apparatus independently of the time-registering device through the mileage or other device driven from the vehicle or machine. The time registering discs 2, and mileage registering discs 3, Fig. 6, are independently mounted on the spindle 4 in the frame 5. The clock movements are mounted in a frame formed by spaced parallel plates including the plate 6, Fig. 1, and secured to the base plate 1 adjacent to the frame 5. The time registering discs 2 are driven from a pinion 13a on the minute hand of a driving clock while the discs 3 are driven from a spindle 16 carrying a gear wheel 17 driven from the vehicle. The driving clock comprises a spring drum a geared through a train t to a minute arbor u carrying the pinion 13a. Another clock drum drives through a gear train the arbor u<b> and controls the driving clock through an escapement 22 operated by a ratchet wheel 21 on the arbor u<b>, on the end of which is a hand x moving over a dial y. The pallets 24 at one end of the pallet levers 23 engage the ratchet wheel 21, while pallets 25 at the other end engage the scape wheel 22, the gearing being chosen so that the registering discs 2 get an impulse every minute. The ink ribbon 26 is carried on rollers 27, a driving roller 28, and a tensioning roller 29, and lies between the discs 2 and 3 and the record sheet 12. The spindle 28a of the driving roller projects through the plate 1 and carries a toothed wheel 28b, Fig. 2. The paper roll is housed in a drum 31 provided with a lateral opening 32 through which the sheet 12 is led out over the platen 37 and drive roller 38 to a take-up spool 41. The platen, which extends across the record sheet, is carried by one arm 49 of a crank lever 48 of which the arm 50 is engaged by a cam 51 on the spindle 52. This spindle passes through the plate 10 and is squared to receive a key while the other end passes through the base plate 1 and carries a toothed wheel 53, Fig. 2, gearing with a pinion 54 and with idler pinions 64, 65. The spindle 55 carries a ratchet wheel 56 engaged by a driving pawl 57 eccentrically pivoted at one end of a spindle 58 the other end of which carries pinion 59. This wheel is driven through worm and spur gearing 82, 61, 60 from a shaft 81. The pinion 61 drives through a clutch the spindle of the spool 41. The pinion 65, through suitable gea.rs, drives the record sheet and ink ribbon spindles 38<a>, 28a. The pinion 54, through gear wheels 74, 75, 76 and 17, drives mileage discs 3. The mileage discs 3, the record sheet 12, ribbon 26. and platen 37 are thus all intermittently driven through gear trains actuated by the driving pawl 57 through the ratchet wheel 56. The discs 3 and the inking and record strips are fed forward in the interval between the actuation of the platen. The cam spindle 52 may be operated by a hand key for checking and setting the records, while the clocks can be regulated by the hands x, y. The gear train at the back of the base 1 is operated by a worm shaft 81 adapted to be coupled to a flexible shaft. driven from the vehicle. The worm shaft 81 also automatically winds the two clock mechanisms through a worm gear 87 and a free wheel device and slipping clutches.
