The Hattersley Domestic Loom was part of the Hattersley Domestic System that include other machines such as pirn winder and warping mill. It was a compact machine, combining all the know how and precision engineering of the nineteenth century with the need for a treadle operated loom. This looms has tappets to control up to 8 shafts, healds or boards; most simply have 4 shafts and a set of four 2/2 Twill tappets and four plain weave tappets. 5,6,7,and 8 pick tappets were available. In order to cope with the different gearings the tappet drive cog on the bottom drive shaft could be adjusted and there are two sizes of tapped mounting drive cogs. There was also a Dobby version. The first thirty Hattersley's were sent to the Outer Hebrides in 1919. These were 36 inches in the reed space and single shuttle. In 1924 the first six shuttle, 40 inch reed space looms arrived in Stornoway and this type of loom was the most commonly used loom in the islands' Harris Tweed Industry.
