Abstract: 1,167,783. Selective printers. BRUNSWICK CORP. 31 Jan., 1967 [8 July, 1966], No. 4672/67. Heading B6F. Type-case machines; type-wheel machines; machines with two or more sets of types.-A selective printer system for a bowling alley includes four printers, P 1  . . . P 4 , Fig. 1, each printing any bowler or team score on a score sheet 48 in any frame for any plurality of bowlers or teams and including a platen 42, Fig. 12, for the score sheet 48, a printing carriage 41 having a plurality of type sheets 222, Figs. 14, 15, mounted on pivotal arms 201 . . 211 pivotally supported on support arms 214, the printing carriage 41 being reciprocated in a plane parallel to the platen from a position removed from the platen to a printing position overlying the platen, in which latter position the pivotal arms 201 . . . 211 are selectively released for the type wheels to be impelled by springs 224, Fig. 15, against the score sheet 48 on the platen 42. The printers P 1  ... P 4 , Fig. 1, are driven by a common drive belt DB trained over respective drive and idling pulleys 30, 33, individual drives for the printing carriages, which are reciprocated a printing stroke along guide bars 47a, being provided by belts PB trained over drive pulleys 36 and idler pulleys 32, 35, 37 to 39. Type character selection; power and electric signal assisted type actions.-The type character 220, Fig. 15, to be printed in any particular line or frame on the score sheet 48 is selected by the transmission of an output signal from a computer (not shown) to a segment on a commutator 90, Fig. 1, whose output is applied to a respective one of a plurality of annularly disposed character selecting solenoids CHS, Fig. 12, provided with pivotally mounted pawls 274 (Fig. 18) which are displaced into the path of a radial lug on a rotary member fast with a gear 264, Fig. 19, which meshes with gears 262, 260. The latter is mounted on a shaft S which supports gears 232, Fig. 14, one for each type wheel 222, to rotate the latter through intermediate gears 228, Fig. 15, and 226, when in response to actuation of a singlerevolution clutch a shaft K, driven by the driving pulley 36 (Fig. 22) oscillates a link 288 through a bellcrank 284. The link 288 oscillates in turn a crank arm 292 to displace angularly by frictional engagement the gear 262, to drive gear 264 until the latter is arrested by engagement of the pawl 274 with the radial lug. The rotation of the gear 262 is transmitted by the shaft S and associated gears to the type wheels 222. The selected type wheels 222 are released for impression first by a common bail 234, Fig. 15, and secondly by selectively actuated latches (242, Fig. 16) released by associated solenoids (FRS, Fig. 16) one for each print arm 201 . . . 211 to cause impression in selected frames on the score sheet 48. Type aligning and resetting arrangements.- The type wheels 222 are aligned for impression by a lug 302, Fig. 19, on a cam actuated lever 298 and the released print arms 201 . . . 211, Fig. 12, are reset by a cam actuated bail 248 and interlocked by the common bail 234, Fig. 15. Type-carriages; letter and line spacing arrangements; tabulating arrangements.-The type carriage 41, Fig. 14, is mounted on the slidable guide rail 47a, Fig. 1, along which it is reciprocated by a cam follower 51 pivotally mounted on a fixed guide 47, Fig. 5, and slot-pin connected to the guide rail 47a. The cam follower 51 is provided intermediate its length with a cam follower pin 52 disposed in a face cam groove 54 of a cam plate 50, which is rotated by gears 64, 82, 86 in response to actuation of a clutch 65 by a computer signal applied to a solenoid A (Fig. 8) which pivots a pawl 71 in an anticlockwise direction to cause the clutch 65 to drive the cam plate 50, whose cam groove 54 has an undulated configuration to advance the carriage intermittently through 13 different line spacing positions during each revolution of the cam plate, a dwell on the cam plate causing the carriage to be temporarily arrested for impression. Since each type wheel is used to print in a number of columns in a score area, i.e. print units, tens, hundreds and thousands, the carriage 41 includes a frame 219, Fig. 14, which is laterally slidable on a pair of shafts K, A and spring biased into contact with a cam 326 fast with the shaft K. Rotation of the cam 326 causes the frame 219 to move towards the cam 326, the frame movement being arrested selectively at one of column positions by a stepped abutment member 320 which coacts with one of column solenoid COS-10 . . . COS-1000 actuated interposers 328-10 . . . 1000 mounted pivotally on a pin 330. The frame 219 is returned to its home position by the cam 326 after each printing cycle.
