Hand-loom.
A form of loom in which the motions are derived from hand power, either by a crank or by pushing the lathe or batten.
In the example,

the driving shaft, at the front end of the machine, is provided at its middle with a crank, so as to enable the weaver to use both hands when required, and also to reach any broken thread in the warp.
A feed pawl attached to a fly-wheel on the driving shaft operates a ratchet-wheel on a rearward shaft, provided with tappets which depress in succession the treadles.
The picker staff projects from a shaft journaled vertically to the batten, and on this shaft is a strap, the ends of which are divided and secured to the alternate treadles.
Thus the harness, let-off, take-up, and shuttle motions are all derived from the crank which is by the breast of the weaver.
