mode of lifting the warp, or chain as it is called, so as to throw a much greater portion than usual of the weft, or shoot on to the face of the cloth; for the purpose of increasing the quantity of pile, and thereby improving the appearance of the cloth when finished.

The beating up of the weft, which in ordinary looms is produced by the hand of the weaver, who brings the lay forward with two smart strokes, which strike the reed against the weft thread, is, in the present improved loom, effected by means of a spring or springs attached to the breast beam, and to the lower bar of the lay.

The movements of the loom are produced by rotatory wheels with cams or tappets acting upou the different parts of the machinery, as may be seen by reference to several patent power-looms described in our Journal, (see Bowman's patent, Vol. II, Roberts' Vol. VII, Buchanan's, ib. and others in our subsequent volumes). The present

patentee, however, does not claim the modes of moving the operative parts of the loom, but simply under this head, the spring or springs, for drawing the lay forward, with considerable force.

In order however, to explain this invention, it is necessary to say, that immediately beneath the lay, there is a rotatory cam, which as it revolves, acts against a piece extending from the under part of the lay, and by that means, forces the lay back, and retains it in that position while the shuttle is passing across, between the sheds of the warp. As soon as the shuttle has passed, the cam escapes from the lay, and allows the spring connected to the lay, and to the breast beam, to pull the lay forward with considerable force, which causes the reed to beat up the weft as above said.

Various kinds of springs may be employed for this purpose, provided they are so placed as to draw the lay

toward the breast beam. A long blade spring is pro posed, which is made fast to the breast beam at one end, and is attached to the lay near the middle, by a swivel joint; or, instead of being immediately attached to the lay, two other blade springs may be affixed to the lower bar of the lay, and these attached to the acting end of the former, which it is considered would soften the beating up stroke, and yet give all the required force. Or instead of these blade springs, helical wire springs might be employed, one end of the spring being secured to the breast beam, and the other to the lay.

The improved mode of lifting the warp, is by the employment of three headles as the harness, one third of the warp threads being tied up by each headle, and these being made to rise one at a time in succession by the movements of the machinery, previously to every throw of the shuttle, cause only one third of the warp threads to be above the weft, while two thirds are always below it. By this arrangement a greater portion of the weft is thrown on to the surface of the cloth on the right side, and the means afforded of drawing out a larger quantity of pile, which greatly improves the face of the cloth, when the giging, shearing, and dressing, has been completed.

To WILLIAM GRIMBLE, of Cow-cross Street, in the County of Middlesex, Gentleman, for his Invention of certain Improvements in the construction of Apparatus for Distilling Spirituous Liquors.

[Sealed 14th May, 1825.]

THE apparatus proposed as the subject of this patent, is

intended to be adapted to the ordinary still, and to be interposed between the head of the still, and the worm tub, for the purpose of catching the aqueous parts of the vapour, driven off in the process of distillation, and conducting them back again into the still while the alcoholic vapour or spirit is allowed to pass into the worm, and become condensed as usual.

Plate VIII, fig. 2, represents the apparatus partly in section; a, is the head of a still, on to which a square rim b, b, is fitted and secured air tight by luting; c, is a plate to which the rim is made fast. This plate is perforated with holes, from each of which a pipe d, d, d, rises, and through these pipes the vapour proceeding from the still is intended to pass into the close box e, e.

Within the box e, there are a series of tubes f, f through which the atmospheric air is allowed to blow, for the purpose of presenting a cold surface to assist in condensing the vapour as it rises into the box. These tubes may be carried in any direction through the box, or may be coiled round within it, as may be found most convenient, the air of the atmosphere being allowed to pass through the tubes freely.

The bottom of the box e, is made convex, for the purpose of conducting the condensed vapour to the corners of the box, where there are tubes g, g, by which the liquid flows down into the still below. The lower ends of these tubes g, are bent round, in order to enable them to hold a small quantity of the condensed liquor, which prevents the vapour from the still rising up those tubes.

The apparatus so constructed and attached to a still, causes the aqueous parts of the vapour, arising from the distillaton to be arrested in the box e, and conducted down into the still below, while the alcoholic vapour which is not condensed by the cold air tubes, passes off by the

pipe h, to the worm in the worm tub, where it becomes condensed in the usual way. A thermometer i, is proposed to be inserted into the box c, for the purpose of shewing the temperature, and enabling the director to regulate his fire; or, in place of this, a pyrometer may be placed within the head, and its outer extremity made to act upou certain levers connected to an index and dial plate, for the purpose of shewing the degree of heat within.

The form of the apparatus, and the precise number of pipes, is a matter of little or no consequence, the patentee proposes it to be square, and to have 672 pipes, but does not confine himself to that particular shape, as it might be round or of any other form; neither is that exact number of pipes essential, as a greater or less number may be employed, according to the size of the apparatus.

TO THOMAS WORTHINGTON the Younger, and JOHN MULLINER, both of Manchester, in the County of Lancaster, Small-ware Manufacturers, for their Invention of, and Improvements in, the Loom or Machine used for the purpose of Weaving, or Manufacturing of Tape, and such other Articles to which the said Looms or Machines may be applicable.

[Sealed 21st June, 1825.]

THIS invention consists of certain appendages to be applied to a loom for the purpose of accommodating the delivery of the warp threads to the speed with which the work is taken up upon the beam or roller. - The improve

ments are designed principally for, if not exclusively applicable to those looms which are employed for the weaving of tapes, and such narrow goods or small-wares.

Plate VIII, fig. 3, is a side view of the frame-work of a loom, intended to be worked by the power of steam or water, in which representation the novel features are shewn, but many of the old parts are omitted to avoid confusion ; a, is a rigger upon the main shaft b, which receives its motion by means of a band from a steam engine; c, is the warp roll or bobbin from which the yarn or thread is drawn, that produces the warp; d, is the work roll or beam, upon which the work ultimately is taken up as it becomes woven.

The course in which the warp threads are conducted from the roll, c, is shewn by the line e, e, e. The warp having proceeded upwards from the roll c, passes over the rollers f, and g, and under the roller h, then up again over the roller g, and downwards under the roller i, from whence it proceeds on through the heddes k, and lay, where the shuttle passing to and fro between the open warp, weaves the fabric; which being conducted over the breast beam m, proceeds round the rollers o, and p, to the work-roll d, before mentioned.

A toothed-wheel affixed to the shaft b, on the opposite side of the loom, takes into and actuates another wheel at the end of the tappet-shaft, (neither of which however are shewn in the figure,) because they form no part of the present improvement. By means of this gear, the evolutions of the loom are performed in the way that power looms are commonly put in action.

At the end of the tappet-shaft there is an endless screw ¶, which takes into pinions on the ends of the lateral shafts r, and s. At the reverse end of these shafts, there are also other pinions: that of the shaft r, taking into the be
