  • the summation unit or summer SSD (FIGS. 3 through 7) includes a frame 504 mounted by suitable brackets and including a plurality of crossframe or pin members 505 secured to opposite sides of the frame 504 at their ends.
  • a plurality of slide bars 813-1 through 58-10 are mounted on pin members 505 extending through elongate slots 506 in the SB slide bars. Slots 506 permit longitudinal sliding of the SB slide bars to the left and right while retaining the slide bars against vertical movement as viewed in FIG. 3.
  • a plurality of 10 pin-count magnets M-I through M-10 are mounted by brackets 507 to frame 504 disposed above slide bars SB-l through SB-IO as viewed in FIG. 3.
  • a plate 508 is pivotally mounted on a pin 511 for association with the core of each of magnets M-l through M-10. Pin 51! is secured between opposing walls of frame 504.

  • the plate 508 therebeneath is moved to an attracted position as shown for the magnets in FIG. 3.
  • the plate 508 Upon deenergization of each magnet M-l through M-10, the plate 508 is released and is moved by the urging of spring 514 to the position shown in dotted lines for the plate 508 beneath magnet M-S in FIG. 3.
  • plate 508 When in lowered or unattracted position, plate 508 carries latch end 512 into lockable engagement with a receiver or notch 515 in one of the SB slide bars as seen in dotted lines by magnet M-5, FIG. 3.
  • the latch 512 of each plate 508 is disposed laterally as best seen in FIGS. 4 and 5 for lockable engagement with the SB slide bar bearing the same numerical designation as the M magnet operating the given plate 508; thus, for example, upon release of plate 508 by magnet M-7, the latching end 512 of the plate is free to latch in notch 515 of slide bar SB-7.
  • Each of the other magnets and slide bars of identical numeral suffix are in the same manner associated through a plate 508 and latch 512, so that when the magnet is deenergized the latch 512 is free to be urged by spring 514 into the notch 515 of the slide bar to latch the slide bar against longitudinal sliding. Upon energization of any one or more of the magnets, the corresponding slide bar is unlatched and free for longitudinal sliding movement.
  • Each of slide bars SB-l through SB-10 includes a lower projection 525 disposed to engage the pin 520 supporting the pulley having the same numerical suffix as the slide bar.
  • the pulleys P-l through P-IO vary slightly in diameter.
  • the pulleys are of increasing size and diameter in the following order: P-7, P-3, P-6, P-4, P-8, P-5, P-9, P-2, P-10 and P-I.
  • Disposed around the assembly of pulleys in inverse block and tackle fashion is a flexible nonstretching tape 526.
  • the signals from the PDS pin detection switches in pinsetter AP are fed through blocking diodes to the magnets M-l through M- respectively in summer SSD so that closure of a PDS switch will cause actuation of the M magnet having the same numerical SUfflX when switch CPS in the common of all M magnets is closed.
  • energization of each magnet represents a pinfall count of one.
  • a latch 512 is withdrawn from the slide bar SE.
  • the tension on tape 526 pulling through the inverse block and tackle arrangement will thereupon cause pivoting of the corresponding pulley about shaft 524 toward the center of the block and tackle arrangement carrying the projection 525 on the corresponding SB slide bar therewith.
  • any unlatched slide bar will permit sliding motion and consequent pivoting of the corresponding pulley while any latched slide bar, i.e., where the M magnet is deenergized, will stop such pivotal movement of the corresponding pulley.
  • Slide bars SB-l through SB-5 slide to the left under urging of the pulleys, and slide bars SB-6 through SB-10 slide to the right when the corresponding magnet is energized, tension being constantly maintained on tape 526.
  • the SB slide bars are adjusted, as will be seen, so that each slide bar permits almost the same exact length of tape to be pulled for each magnet energized.
  • the amount of movement of tape 526 from the device can be taken as a mechanical measure of pinfall count, the tape moving one unit for each pin downed.
  • each SB slide bar is limitedby means of adjusting bolts 528 at the end of the slide bar toward which the slide bar moves.
  • the adjustments 528 for slide bars 58-] through SB-5 are on the left and the adjustments for slide bars SB-6 through 88-10 are on the right as viewed in FIGS. 3 and 4.
  • the adjustments are conventional, constituting a threaded shaft threaded through a nut secured to frame 504 with the shaft aligned at the end of the respective slide bar as seen more clearly in FIG. 6.
  • the bolt portion of adjustment 528 acts as a stop in the usual manner to limit the travel of the corresponding SB slide bar by abutment of the end of slide bar against the bolt portion.
  • the threads of the adjustments 528 are sufficiently fine to permit adjustment of the amount of travel of each slide bar within 1/1000 inch of each other. Thus, essentially the same distance is traveled by the center of rotation of each pulley when released and moved by tape 526, the limit permitted by the corresponding slide bar.
  • Each unit of measure added to tape 526 will, for practical purposes, be the same and will be equal approximately to twice the distance of travel of the center of rotation of each pulley.
  • the summing device is triggered by a momentary signal from the computation and control system at the beginning of each computation cycle to clear the M magnets prior to introduction of new pinfall information from the PDS switches, as fully illustrated by Cornell et al. in application Ser. No. 366,297.
  • This signal actuates the control magnet of a magnet actuated one-revolution clutch 530.
  • a motor 531 which may be a constantly driven motor, driving shaft 532, engages shaft 534 through clutch 530 for one revolution to rotate shaft 534 one revolution.
  • Shaft 534 carries a cam 537 which protrudes through apertures 538 in each of the slides SB.
  • cam 537 protrudes through apertures 538 in each of the slides SB.
  • cam 537 rotates clockwise, the first of cam 537 rotation resets the summer by erasing previous data as viewed in FIG. 3.
  • the M magnets are in the normally deenergized state and latches 512 of each deenergized magnet have fallen to the top edge of the respective slide bar and rest thereon.
  • cam 537 passes 45 of rotation, it begins to pick up any slide bars which were unlatched in the previous cycle, by engagement within aperture 538, and as cam 537 reaches 135 of rotation, the slide bars have been carried back to their reset positions.
  • the pinfall switches in the pinsetter are reset by cycling of pinsetter as described by Cornell et al.; a subsequent energization of the magnets by the pinfall switches will be attributed to a subsequent ball. If the pinfall switches in another pinsetter serviced by the summer are ready to give information to the summer, this information will at this time be picked up with the summer again acting in the manner described above.

  • stepped cam 561 is provided in order to enter less than 10 pins into the computer for calculation of score.
  • steps 1-9 inclusive of the stepped cam has the same approximate angular length.
  • stepped cam is rotated clockwise by its torsion spring one step for each unit of measure representing a pin down in tape 526.
  • cam 561 As cam 561 is rotated clockwise by releasing of the tape, for each unit the tape is released, the cam rotates an additional step relative to a pin 567 which protrudes outward through a slot. Pin 567 is secured to elements in the computer for entering the pinfall count into the computer to be used in calculating a score value which is awarded to the proper bowler as more fully described by Cornell et al. in application Ser. No. 366,297.
  • the split detection system is identified generally by reference number 601 (FIG. 3). It will be noted that slide bars SB-l through extend from the summer into split detector 601. In their extending portions, the slide bars have a series of highs 602 and lows 603 (FIG. 8) which may move into or out of alignment with each other, depending on the various combinations of movement of the slide bars with and/or relative to each other during the totalizing procedure described above.
  • the movement of the slide bars is a mechanical input to the split detector 601 and the split detector examines such input for existence of nonsplit conditions, converts the absence of nonsplit conditions into an indication of a possible split condition and further examines the input and such possible split indication to determine whether a split has actually occurred. If a split has occurred, the printer is directed to print a split symbo1S.”
  • the corresponding slide SB When the appropriate magnet M is energized, the corresponding slide SB is moved approximately one-tenth of an inch to the right or left during the pin summing procedure a precise unit, e.g., one-tenth inch as represented by the length of the double arrowed line above SB-2 in FIG. 8.
  • the slides SB are configurated with the lows 602 and highs 603 to present alignment of a set of lows 602 across the entire plurality of the slide bars and in alignment with a feeler system, as will be described, for the majority of occasions where a pinfall condition exists which cannot possibly be a split.

  • Gear 612 is in mesh with beveled gear 613 which is secured to shaft 534 so that rotation of shaft 534 drives cam 611.
  • Detection of nonsplit combinations and the basis for such detection by the present system can be understood with reference to FIG. 9. Assuming elimination of all pinfall conditions in which the head pin is left standing and more than eight pins have been knocked down, the remaining fundamental nonsplit combinations can be grouped in 11 groups as illustrated in FIG. 9. By way of explanation, there are 1,024 possible pin combinations following first ball, including a situation where there are no pins standing, and the assumption that the head pin has been knocked down eliminates the one-half of these where the head pin is still standing. Of the remaining 512 combinations, 459 combinations are herein recognized as splits, 52 are nonsplits, and the remaining I is the strike combination where all pins are knocked down.
