Definitions

  • ABSTRACT A device for periodic recording of traffic flow on roads or of liquid level of a river by printing on paper tape the positions of a set of counter print wheels of a mechanical counter that is driven in response to vehicular traffic or to a change in liquid level. As a traffic counter the device provides automatic periodic resetting of the wheels to zero.
  • a novel, disposable printing ribbon cartridge permits construction of the device with rigid support, by spaced vertical plates secured to each other and a base plate, of both ends of the counter as well as of an assembly of print rolls to improve printing while avoiding threading of the ink ribbon.
  • a corelator-locking mechanism of the device fixes position of the wheels during printing.
  • a onepiece counter wheel, with a pawl mounted in it for resetting to zero, provides more rigid faces for the decagonal periphery.
  • the most pertinent prior art device is a traffic counter previously made and sold by the Streeter Amet Division of the assignee of the present patent application under the trademark Recodet.
  • the device of the present invention includes a counter-printer with the counter being driven by a motor that is driven by pulses generated through a system.
  • a base plate supports a single vertical plate that provides only cantilever support to the mounting bracket that supports an assembly of printing rolls above the counter wheels. Those rolls are moved in a rocking motion across and then back across the printing zone. This motion with the double passage of the rolls through the printing zone can result in a poor quality print if the paper has moved slightly before the return movement.
  • the assembly of counter wheels on their shaft have that shaft supported in a cantilever manner by its support at one end by a plate supported by the vertical plate and not also directly supported by the base plate.
  • That traffic counter had counter wheels constructed of two pieces to enclose a spring-loaded pawl used for resetting.
  • One piece was a disc with a peripheral flange having a decagonally shaped outer surface and a cylindrical inner surface. The other piece fit inside the flange and the two pieces were secured together.
  • This construction did not provide the rigidity at the perimeter required for accurate definition of printing. Such accuracy is needed because tape is printed to duplicate long and short line indicia corresponding to that embossed on the particular portion of the peripheral surface of the wheel. Those indicia on the printed tape are optically read by a tape reader to convert the information to a more useful form.
  • U.S. Pat. No. 2,195,869 discloses a recording device stated to be useful to record traffic flow using a mechanical counter with a printing mechanism and using a continuous ribbon and an ink-supply roll.
  • the ribbon passes through the printing zone in the direction of travel of the paper tape to be printed and this must be of substantial width.
  • the shaft for the counter wheels is supported in a cantilever mounting. Quality of the inked ribbon is dependent on the efficacy of the ink supply roll and that will vary with temperature and presumably with time.
  • the device of U.S. Pat. No. 2,688,445, similar to U.S. Pat. No. 2,195,868, passes an ink ribbon through the printing zone in the direction of travel of the paper tape.
  • the device has two spools for the ribbon and they are on opposite sides of the printing zone. Manual threading is required.
  • the width of the ribbon must equal the transverse width of the printing zone occupied by counter wheels.
  • Ink ribbon cartridges are used in some typewriters. See U.S. Pat. No. 2,986,260. These, like magnetic tape cartridges exemplified by U.S. Pat. No. 3,075,717, have a ribbon on one spool and connected to a second spool mounted on parallel axes in a casing of the cartridge with none of the length of the ribbon between the spools being oriented by guide means integral with the cartridge in a path that presents the operating surface of the ribbon at a working zone in a plane other than parallel to the axes of the spools.
  • Other patents disclosing replaceable ribbon cartridges are U.S. Pat. Nos. 3,075,627; 3,513,957; and 3,615,155.
  • U.S. Pat. No. 3,549,823 has guide means to change the orientation of the ribbon to parallel to the common axis of the spools but this is provided merely to change direction and elevation. There is no change at the working zone.
  • the recording device of the present invention includes a rigid support assembly comprising a base plate, a rear vertical main plate fixedly mounted on the base plate, and a front vertical auxiliary plate fixedly mounted on the base plate in parallel with but spaced from the main plate, and standoff rods between and fixedly secured to the vertical plates.
  • the device also includes: a counter assembly having counter wheels and mounted on and between the vertical plates at a printing zone; a printer assembly mounted on and between the vertical plates and below the counter assembly; power-driven means mounted on the support assemblyto move a printable tape in a horizontal path of travel through the printing zone parallel to the vertical plates and between the counter wheels and the printer assembly; means mounted on the support assembly to support the tape at a horizontal plane before passage of the tape below the counter wheels; means mounted on the support assembly to support the tape at said horizontal plane after passage below the counter wheels; and an ink ribbon cartridge mounted on the support assembly and containing a casing, an ink ribbon, a supply spool for the ribbon and rotatably mounted on the casing, a takeup spool for the ribbon and rotatably mounted on the casing, and guide means as an integral part of and adjacent one end of the cartridge to direct a part of the ribbon extending between the spools in a manner so that a printing surface of that part of the ribbon is at the printing zone below the counter wheels and extends
  • the device of the invention preferably has more specific construction for some of its components mentioned above as will be apparent from the detailed description.
  • components are included for automatic periodic resetting of the counter wheels at selected predetermined periods of time, such as every cycle of printing operation.
  • the counter wheels have a novel construction to provide a substantially rigid periphery containing embossed indicia at each of its polygonal side portions.
  • Each counter wheel is constructed to provide radial support to the central opening across the entire width of each polygonal side portion instead of being constructed with polygonal side portions as parts of a peripheral flange without such support.
  • Each counter wheel is a one-piece construction.
  • the counter wheel is a one-piece component of a counter wheel subassembly for the counter assembly.
  • the other components of the subassembly are a pawl, a spring and a pin mounted and secured in a noncentral hole.
  • the pin has an enlarged head and the shank adjacent the head is enlarged.
  • the noncentral hole is enlarged by a deep recess at one face of the wheel and the outer portion is further enlarged by a shallow recess to permit pivotal movement of the pawl on the enlarged shank portion of the pin above a spring helically wound about the enlarged shank in the deep recess with one free end of the spring abut a wall portion of the deep recess shaped to prevent rotational movement of the spring in one direction about the pin.
  • the other free end of the spring engages the pawl so that the pawl is biased into the central opening of the wheel to engage a notch in the shaft on which the wheel is rotatably mounted. This engagement rotates the wheel when the shaft is rotated in one direction but, of course, permits free rotation of the wheel in the same direction relative to the shaft.
  • This one-piece counter wheel is molded thicker than the width of the polygonal sided periphery and has a coaxial integral gear on one face. Between the polygonal-sided periphery and the other face the periphery is multistepped to provide at the outer stepped portion adjacent that face a star gear having the same number of teeth as the sides of the polygonal sides of the periphery with the base between each tooth aligned with the center line of each polygonal side.
  • the intermediate stepped portion provides a locking ring that is notched in alignment with and shaped like the notch between the teeth of a two-tooth segment integral with it and extending toward teeth of the star gear.
  • the locking ring and the two-tooth gear segment have a slightly larger diameter than the diameter of the integral gear on the other face of the wheel and thus on the corresponding integral gear of the next higher order gear that is engaged by the pinion turned by the gear segment.
  • brackets for pinion gears makes possible the avoidance of ambiguity due to marginal pinion engagement as can occur when there is a common shaft on which pinions are rotatably mounted and which is mounted on a bracket pivotally mounted for movement of the pinions away from the counter wheels by the gears during the resetting of the latter.
  • the means to rotate the shaft, on which the counter wheels are mounted is constructed to turn the shaft through two complete revolutions to eliminate any remaining possibility of reset error that may occur otherwise when under certain conditions the counter wheel is positioned to indicate a print of nine for the wheel at the time reset is started or if the reset pawl should fail to drop into the notch of the shaft mounting the wheels after a wheel completes a revolution and the counter wheel is then positioned to indicate a print of zero.”
  • the disclosed embodiments of the present device contain the star gear on each device to be engaged by a rocked correlator-and-locking mechanism of the device. That mechanism is pivotally mounted and has fingers engaging the star gears prior to printing to ensure horizontal positioning of the downwardly facing side of the polygonal periphery indicating that digit of the decimal number counted or otherwise indicated.
  • the device is maintained locked in correlating position until completion of a printing operation.
  • the device includes means operatively associated with means to move the printer assembly to perform this function so that the fingers are moved into and out of position, before and after, respectively, the printing operation.

  • the ribbon 168 is wider than necessary for use if its transport were parallel to that axis of revolution. However, the oblique transport virtually eliminates use of any given portion of the ribbon for a second time. This provides a larger number of printing uses of maximum quality for a given length of ribbon and thus increases the time between replacements of cartridges.

  • the shaft 88 has a longitudinal rightcangled notch 210 with a radial wall so that engagement of pawl 209 in notch 210 results in resetting by counterclockwise rotation (as viewed in FIG. 20) of shaft 88 when shaft 88 is thus rotated, but counterclockwise rotation of the counter wheel does not turn shaft 88.
  • Each counter print wheel has a decagonal periphery to provide ten print sides that are flat except for raised indicia comprising one of the numbers from to 9 and one of 10 combinations of a set of parallel lines that are short or long to indicate by a binary code the number appearing on the same print side.

  • gear 210 has an outer diameter of 0.955 inch
  • locking ring 214 can have a suitable larger diameter of 0.975 inch. This prevents ambiguity when pinion 211 is pivoted away momentarily from gear 208 as it is rotated during resetting of that counter wheel. The pivotal movement of pinion 211 away from gear 208 is insufficient for the teeth of pinion 211 to clear locking ring 214 of the next lower order counter wheel for an undesirable degree of turning of pinion 211.
