Hand loom with dobby mechanism, drop boxes and numerous accessories

This loom differs from others chiefly in the arrangement for raising and lowering the shafts; it consists of pegs inserted in holes in wooden lags, travelling round a spindle turned by a hand wheel at the front of the loom. Dobbies are used for patterns which are beyond the range of tappets but not sufficiently complex to require jacquards. There are 25 heald-shafts and three shuttle boxes on each side. Pegs are inserted in the lags according to whether in any one pick, or throw of the shuttle, a warp is shown in the design as passing over or under the weft. The peg pro- jecting from the face of the lag presses against one arm of a fork, the other arm of which is connected with a vertical hook from whose lower end the heald shaft hangs. A horizontal knife is raised by pressing down on a pedal at the front of the loom and in its motion upward it carries with it all the hooks which have been pressed by pegs towards it. A quarter turn of the hand wheel in front brings another lag with its pegs into operation for the next pick.
