TO WILLIAM HENSON, of Allen-street, Lambeth, in the county of Surrey, engineer, for improvements in machinery for making or producing certain fabrics, with threads or yarns, applicable to various useful purposes. -[Sealed 19th November, 1840.]

THESE improvements consist in certain novel arrangements or constructions of machinery, whereby looped or knitted fabrics are produced, similar to those manufactured in the ordinary warp-frame, but in a more expeditious manner.

The fabrics may be used for a variety of purposes; for instance, a close fabric may be produced, extending throughout the width of the machine, which may be afterwards cut up, and formed into various articles of dress; or it may be made in narrow widths, with selvages, for the purpose of being applied as surgical bandages, and for other purposes; or, when manufactured from woollen yarns, may be subjected to the operation of fulling or felting, in order to produce an appearance, resembling a closely woven woollen cloth. And also, by the same machine, open

or fancy work, such as is usually called "tattings," may be produced, if desired.

In his specification, the patentee's improvements are shewn, applied to the production of a closely-knitted fabric, extending along the whole width of the machine.

In Plate VI., fig. 1, is a front elevation of the machine, the top rail of the frame-work and work-roller, with its appendages, being removed, in order to expose such parts as lie immediately behind them; and fig. 2, is an elevation, shewing the right-hand end of fig. 1. Fig. 3, is a vertical section, taken transversely through the machine, in the line a, b, of fig. 1, looking towards the left-hand; and fig. 4, is a similar section, taken through the machine, in the line c, d, of fig. 1. Fig. 5, represents a detached portion of the machine, partly in section, taken in the line e, f, of fig. 1, looking towards the right-hand.

a, a, a, a, is the frame-work, by which the various parts of the machine are supported; b, b, is the main shaft, to which rotary motion is communicated from any suitable first mover, through the pulley c. This shaft carries the wheels or cams which actuate the working parts of the machine, hereafter to be described. d, d, is the warp-roller, on which the yarns or threads are wound, (intended to produce the knitted or looped fabric); and e, e, is the work-roller, on which such fabric is to be wound, as produced by the operations of the machine.

The parts connected with these two rollers, and the apparatus connected therewith, are more particularly shewn in the partial end view of the machine, at fig. 6.

The warp-roller d, d, is mounted, turning in bearings, affixed to the upper part of the frame-work of the machine; on the shaft of which, at each end of the roller, are affixed the ratchet-wheels 36, 36; on which shaft, the pullies 37, 37, are also mounted, but turning loosely thereon. 38, 38, are clicks or palls, turning on centres, formed by ears or lugs. 39, 39, extending from the pullies 37, 37; which clicks or palls take into the teeth of the ratchet-wheels 36, 36.

Weighted cords 40, 40, extend over the peripheries of the pullies 37, 37, in order to give the required tension to
