[*] Optional.
During the periods of four years ending December, 1900 and 1904, there were 34 and 163 British patents respectively granted for inventions relating to devices for the replenishing of weft automatically in looms, which figures bear striking evidence of the amount of energy and inventive talent which have been expended in this direction during the past few years. And how forceful are these figures when contrasted with the number of patents (31) extending over the first period of 61 years. It was, however, not until after the advent, in 1894, of the Northrop automatic loom, which received such favourable reception by American manufacturers, that the adoption of automatic looms was taken into earnest consideration by British manufacturers, many of whom now recognize that in one form or another such looms have a definite sphere of usefulness in the manufacture of a great variety of different classes of fabrics of simple construction and embodying one series each of warp and weft threads.
The Northrop Weft-replenishing Device.
The most characteristic features and essential elements of this device, and also those which distinguish it from all previous inventions of this class, consist of the removal of cops or bobbins of weft that are conveniently retained in a circular rotary hopper or magazine, and of their insertion into a self-threading shuttle, by mechanical means operated automatically either on the breakage or depletion of weft, or else when the weft is depleted to a predetermined amount, as may be elected. The magazine containing the reserve supply of weft is always mounted above the shuttle-box situated on the right-hand side of the loom, as represented perspectively in [Fig. 167], which shows a bobbin-hopper A from which a pusher B is in the act of removing a full bobbin of weft and inserting it into the shuttle, thereby ejecting the previous bobbin C which falls down a chute into a box D.
