RECENT PATENTS.

TO WILLIAM KENWORTHY, of Blackburn, in the county of Lancaster, cotton-spinner, for his invention of certain improvements in looms for weaving.-[Sealed 12th December, 1844.]

THESE improvements in looms for weaving apply solely to such as are worked by power, and particularly to that part of the power-loom known by the name of the "stop-rod," which is for stopping the loom, or throwing it out of gear with the driving-power, whenever the shuttle does not complete its course from one shuttle-box to the other. In ordinary power-looms this is effected by the shuttle acting against a "swell" in the shuttle-box, which communicates the required motion to the stop-rod, by means of a lever, bearing against the swell, and kept in contact with it by a spring. The great objection to this arrangement is, that the shuttle has to overcome the resistance of the spring, and also to raise the weight of the stop-rod lever at every "pick" or throw of the loom, which requires to have a heavy shuttle, a powerful pick, and a slow motion, to work successfully.

The present invention consists in working the stop-rod motion entirely separate from the shuttle by the motion of the slay or lathe alone, thereby relieving the shuttle from the

burden of lifting the stop-rod lever at every pick. By this improvement the patentee states, that he is enabled to drive power-looms at twenty or twenty-five per cent. faster than has been hitherto done, and with much greater safety to the working parts.

In Plate X., two methods are shewn by which the required object, namely, working the stop-rod motion independent of the shuttle, may be effected. Fig. 1, represents a plan or horizontal view of the shuttle-box, and part of the slay of a power-loom for weaving, shewing one of the improved arrangements; fig. 2, is a side view of the same; and fig. 3, is a side view of a different arrangement of mechanism, intended to effect the same object. a, a, is the end or main framing of the loom; b, b, part of the breast-beam; c, c, part of the slay or batten; d, d, the shuttle-box; and e, e, is the swell, which is acted upon by the spring ƒ, f, and which is merely for the purpose of keeping the shuttle in its place in the box, and preventing its rebounding, by bearing against its side. The stop-rod or shaft g, g, is connected to and works the spring-lever (for shifting the driving-strap), which is on the other side of the loom, and not shewn in the drawings; on this shaft the stop-piece h, is keyed fast, which is furnished with a projecting tail-piece i, bearing upon a roller or bowl k, which revolves loosely upon a pin or stud 7; m, m, is a lever or finger which, at every throw or pick of the loom, feels (as it were) whether the shuttle has arrived in the box or not: the shaft g, is furnished with two of these fingers m, m, one acting upon each shuttle-box.

The operation of the apparatus is as follows:-As soon as the batten or slay c, c, (in beating up) arrives directly over its centre, the shuttle n, is driven out of the shuttle-box d, across the loom; at the same time, or nearly so, the inclined portion of the tail i, of the stop-piece h, will have arrived over the bowl or roller k, which will allow the spring 0, 0, to exert its power to bring down the stop-piece h; at the same time causing the fingers m, m, at each end of the stop-rod g, to feel whether the shuttle is in either box; and if such be the case, the swell, bearing against the finger m, will not allow the spring o, to bring down the stop-piece h; but should the shuttle be absent from both boxes, the stop-piece h, will be
