1/02 Dobbies Single-lift dobbies, i.e. dobbies in which the same draw-knife or equivalent operates for every pick (D03C 1/1 takes precedence)
1/04 Dobbies Single-lift dobbies, i.e. dobbies in which the same draw-knife or equivalent operates for every pick (D03C 1/1 takes precedence) Open-shed single-lift dobbies
1/06 Dobbies Double-lift dobbies, i.e. dobbies in which separate draw-knives or equivalent operate on alternate picks
1/08 Dobbies Double-lift dobbies, i.e. dobbies in which separate draw-knives or equivalent operate on alternate picks reversible, i.e. correct sheds open automatically when the loom is driven backwards
1/10 Dobbies Centre-shed dobbies, i.e. shed formed by lifting some threads and lowering the others from central shed-closed position
1/12 Dobbies Dobbies employing toothed gearing instead of draw-knifes
1/14 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46)
1/16 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Arrangements of dobby in relation to loom
1/18 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Knives; Knife frames
1/20 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Hooks; Lifters
1/22 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Needles; Needle boxes; Needle boards
1/24 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Cylinders; Cylinder battens
1/26 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Facilitating engagement of lifting-hooks with draw-knives
1/28 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Facilitating engagement of lifting-hooks with draw-knives by creating and then eliminating back-lash between hooks and knives
1/30 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Facilitating engagement of lifting-hooks with draw-knives wherein all the hooks are disengaged from the knives, and selected hooks then re-engaged
1/32 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Facilitating engagement of lifting-hooks with draw-knives wherein all the hooks are engaged with the knives, and unselected hooks then disengaged
1/34 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Arrangements wherein warp threads pass one another at different heights to avoid congestion
1/36 Dobbies Features common to dobbies of different types (stop motions acting on defective operation of shedding mechanisms D03D 51/46) Card- or chain-saving arrangements, e.g. cross-border dobbies
3/00 Jacquards (controlling jacquard by scanning design D03C 17/06; for gripper Axminster looms D03D 39/08)
