Abstract: On each tooth of the belt one type carrier is pivotally mounted by means of one pin each. The type carrier, which preferably accommodates two type characters, is U-shaped, embracing the belt with a certain amount of play. The play, which exists both in a vertical direction and in the direction of firing of the print hammers, permits an accurate alignment of each type carrier in the guide provided in the printer station.

Abstract: 1,267,082. Selective printing. INTERNATIONAL BUSINESS MACHINES CORP. 29 May, 1969 [1 June, 1968], No. 27175/69. Heading B6F. A printer comprises a print head 1 continuously driven along a printing line, the print head including hammers 3 and a continuously rotated type carrier 10. The type carrier comprises a chain having rubber inserts into which typebars 9 in the form of leaf springs are embedded. The hammers 3 are mounted on a hammer carrier 2 supported between leaf springs 12 and reciprocated during motion of the print head and type carrier by an eccentric or cam 8. The print head may be driven along the printing line by a tape, rope, chain or spindle drive (not shown).

Abstract: 1,261,226. Selective printing. INTERNATIONAL BUSINESS MACHINES CORP. 13 May, 1969 [14 May, 1968], No. 24319/69. Heading B6F. Type elements 3 are attached to an endless band, 1 having teeth on its inner surface by side limbs which engage the sides of the belt and pins (10, Figs. 2, 3) which engage holes or grooves in the teeth on the belt and holes on the side limbs of the type elements. The pins permit the type elements to pivot as they meet a guide 4 so that they are aligned parallel with the back 5 of the guide 4 without tensioning the belt 1. Grooves (11, Fig. 3) in the teeth permit movement of the type elements towards and away from the outer face of the belt.

Abstract: 1,010,983. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 24, 1963], No. 32653/64. Heading B6F. Type-wheel machines; type-band machines; type-bar machines; hammer-impression mechanism; electric signal input arrangements.- A high-speed selective printer used for output units of data processing machines and having types mounted on a rotary-type carrier, a chain or type bars, is provided with an electromagnetically operated drive mechanism for a plurality of hammers 1 comprising a corresponding plurality of electromagnets 11 for each of which the print hammers 1 are adapted to form an armature in that the hammers carry two armature yokes 12, 13 of soft magnetic material, said electromagnets exerting on said hammers a force in the impression direction. Each hammer 1 comprises a bar of rectangular cross-section having a hammer head on its front end and the hammer is mounted on a pair of leaf springs 3, 4 serving also to return the hammer to its rest position after impression. The hammer also carries two U- shaped armature yokes 12, 13, the polar surfaces 14 are inclined and co-operate with like polar surfaces 15 of the electromagnet 11 having coils 16, 17 energized with current pulses J2 and J1 respectively. The pulse J1 is of short duration but higher amplitude, whereas the pulse J2 is of longer duration and is ineffective by itself to displace the hammer into its printing position. For impression, both coils 16, 17 are energized simultaneously by said pulses J1 and J2, but when the short pulse J1 terminates on completion of impression the pulse J2 produces a magnetic force retarding the return movement of the hammer, thus preventing rebound. The return movement is limited by a buffer stop 9 having a mass equal to the hammer 1 and clamped to an elastic separator 10.
