The '''Brother KH-800''' is a standard gauge (4.5mm) manual knitting machine. Released in the early 1970s, it is historically significant for introducing the 8-button patterning mechanism that preceded the modern punchcard system.<ref name="BrotherHistory">"History of Brother Knitting Machines," Brother Industries Archive.

The '''Brother KH-800''' is a standard gauge (4.5mm) punchcard knitting machine.

== Historical Context ==
Before the advent of the 24-stitch punchcard, Brother utilized a system of 8 buttons to select needles for patterning. The KH-800 allowed for Fair Isle and Tuck stitches by manually depressing combinations of these buttons in sequence with the row counter.<ref>Newton, Eileen. ''The Machine Knitting Book'', 1974.</ref>

== Key Features ==
* '''8-Button Selection:''' Patterns are limited to 8-stitch repeats. This system requires the knitter to manually change button settings every row or every few rows to create complex motifs.
* '''12-Stitch Punch Card System:''' Unlike the later 24-stitch standard, the KH-800 uses cards with a 12-stitch width. This allows for automatic patterning for tuck, slip, and fair isle, though with a smaller repeat size than modern vintage standards.
* '''Metal Bed Construction:''' Known for extreme durability, though it lacks the "sinker posts" found on later machines like the KH-881, requiring the use of weights for almost all knitting.<ref name="Service800">"Brother KH-800 Service Manual," Machine Knitting etc. [https://machineknittingetc.com/brother-kh800-user-guide-and-service-manual.html accessed Feb 2026]</ref>
* '''Metal Bed Construction:''' Known for high durability and a rigid metal bed housing 200 needles at a 4.5mm pitch.
* '''Lace Carriage:''' It was one of the first models to support a semi-automatic lace carriage, though it requires multiple passes compared to the "Fashion Lace" carriages of the 80s.
* '''Manual Needle Selection:''' While it features a punch card for automatic patterning, it also supports manual selection for specialized stitch work.
* '''Lace Capability:''' Compatible with a dedicated lace carriage that utilizes the 12-stitch card system for transfer patterns.

The Brother KH-800 is a standard gauge (4.5mm) punchcard knitting machine. Released in the early 1970s, it is a significant transitional model as it features a 12-stitch patterning repeat utilizing a specialized punch card system. It served as the predecessor to the more common 24-stitch repeat systems found in later models like the KH-820 and KH-881.

Key Features[edit]

  • 12-Stitch Punch Card System: Unlike the later 24-stitch standard, the KH-800 uses cards with a 12-stitch width. This allows for automatic patterning for tuck, slip, and fair isle, though with a smaller repeat size than modern vintage standards.
  • Metal Bed Construction: Known for high durability and a rigid metal bed housing 200 needles at a 4.5mm pitch.
  • Manual Needle Selection: While it features a punch card for automatic patterning, it also supports manual selection for specialized stitch work.
  • Lace Capability: Compatible with a dedicated lace carriage that utilizes the 12-stitch card system for transfer patterns.

Technical Specifications[edit]

  • Gauge: 4.5mm (Standard)
  • Patterning Width: 12 stitches
  • Needle Count: 200
  • Pitch: 4.5mm

Maintenance[edit]

The KH-800 uses a standard foam-based Sponge Bar (needle retaining bar). Because of the machine's age, this foam is almost certainly degraded in "as-found" units and must be replaced to prevent needle damage or carriage jams.
