form both the lifting and depressing motion alternately. And as the taking-up wheel 11, only performs one revolution to two of the crank-shaft, the pattern will be thus woven upon both surfaces of the cloth, but in reversed positions. As for example:-In weaving a plaid of any required square or pattern, it will be seen, that when the crank-pin 12, in the wheel 11, is passing the horizontal plane of the centre of the wheel on that side represented in fig. 2, the first acting link or row of the bowls, in the endless chain, which forms the pattern, will throw out the required number of jack-lifters x, to the action of the depressing-bar y,2; and by means of the conducting wires y,* cause the said disengaged jack-lifter to be brought against the opposite bar y, ready to be raised. Thus it will be perceived, on the following revolution of the endless chain, the crank-pin, in the wheel 11, will, by passing the horizontal plane of the centre of the wheel 11, at the opposite side, (as shown by dotted lines in fig. 2,) cause those jacklifters x, which were before depressed, to be lifted, and, consequently, produce the pattern reversed upon the cloth, and so on alternately.

The looms, thus arranged, may also be made to work two ordinary calico healds, for weaving stripes or ribs, or plain calico cloth or ground, by attaching their jacks direct to the lifting-bars y,1 and y,2 (shewn also by dots in fig. 2,) in conjunction with any pattern to be effected by the endless chain.

In those cases where it is desirable to attach these improvements, for producing the pattern or figure, to old looms, it is only necessary to adopt the method represented in figs. 9 and 10, wherein the whole of the apparatus, connected with the chain, for producing the figure, will be found to be the same as already described, excepting in

the mode of driving. In these figures 9 and 10, the motion, for working the chain, is to be communicated directly from the ordinary crank-shaft of the loom a, by means of the excentric b, crank c, and slide-rod d. Upon this slide-rod d, the draw-catch e, is attached, for pulling round the ratchet-wheel f, and driving the chain by means of the toothed wheel and pinion g, and h, when the operation of the loom will proceed, as before explained.

The patentee states, "I claim, exclusively, the peculiar construction of the endless chain, composed of side links, spindles or bolts, tubes, washers or collars, and rollers or bowls, revolving loosely, or otherwise, and capable of being readily changed and adjusted, of whatever material they may be constructed, as shewn particularly in figs. 5, 6, 7, and 8, for producing the pattern or figure upon the cloth or fabric, in looms for weaving; and the application of such thereto; and also its employment in conjunction with the taper-formed lifting and depressing-bars or arms y,' and y,2 working in combination with the vertical sliding-rods ≈, ≈, for actuating the jacks and treadles; also in combination with the jack-lifters, provided with two hooks or bearings on each side; that is, on the back and front, in order to perform the requisite and even shedding of the warp threads.

"And, further,—the manner of stringing and connecting the jack-lifters to the treadles, by placing the conducting strings or wires y,* inclined out of the perpendicular, in order to dispense with the necessity of separate springs, in such or similar situations in looms for weaving."-[Inrolled in the Rolls Chapel Office, October, 1839.]

TO WILLIAM HALE, of Greenwich, in the county of Kent, civil engineer, for his invention of certain improvements in machinery, applicable to vessels propelled by steam or other power; which improvements, or parts thereof, are applicable to other useful purposes.Sealed 22nd March, 1836.]

THE patentee proposes, by the friction, in passing of what he calls a strap or band of water, to give rotary motion to a drum, from the axle of which, a driving power is to be derived for propelling vessels, or actuating other machinery.

Plate II., fig. 1, represents, in vertical section, a furnace, in connection with which the apparatus is erected. a, is the fire-place, from whence the flame and heated vapour passes round a circular flue b. In the centre of this flue, a cylindrical vessel c, c, c, is fixed, and within it another cylindrical vessel or drum d, mounted upon an axle e, is enabled to turn freely. Between the outer cylinder c, c, c, and the inner cylinder d, there is a narrow space or channel, which is to be filled with water. The water is to be forced into this channel by a pump, connected to the pipes f; and, after circulating round the passage between the two cylinders, it will be interrupted by a stop i, and pass off by the pipe g. It is intended that the water, in its course, shall, by its friction against the surface of the cylinder d, give rotary motion to that cylinder; the power derived from which, is to be communicated through the axle e, to drive other machinery.

So far, we understand the patentee's intentions, but deny the possibility of producing an available power by any such means. We do not, however, clearly perceive what is intended to be the effect of the fire, acting on one side of the cylinder c; nor do we comprehend what is meant by con

densing, in the pipe g, as steam is not described as the agent, but what the patentee calls the channel or band of water, acting as a strap, passed round the inner drum, which is thereby to be considered as a pulley.

Another modification of the contrivance is shewn in fig. 2; in which, a conical chamber is shewn, and within it is mounted a cone, having a spiral thread or worm coiled round it. Scarcely any explanation of this figure is given, but it is easily understood that the water is to be forced in at bottom, and by acting against the inclined plane of the spiral thread or worm, the cone is intended to be made to revolve, which we presume would be the effect; but with what advantage we know not.-[Inrolled in the Inrolment Office, September, 1835.]

TO HENRY JAMES PIDDING, of Osnaburgh-street, in the county of Middlesex, artist, for improvements in collars for horses and other animals,—being a communication from a foreigner, residing abroad.-[Sealed 27th September, 1839.]

THIS improved collar is constructed upon an iron frame, which gives the collar sufficient rigidity, in itself, to allow of dispensing with the ordinary moveable hames, there being arms carried out from the sides of the frame through the padding, to which the traces are to be attached.

The two sides of the frame are connected together, at top, by a hinge joint, and are capable of opening at bottom, under the throat, by eyes or sockets, at the ends of the frame, sliding upon a straight rod or bar. By these means the collar may be expanded, in width, to suit the neck of any horse; and may be widened, when required, to facilitate the passage of the collar over the horse's head.

Plate II., fig. 1, represents the framing of the collar without its padding. a, a, are the side frames; b, the hinge-joint, upon which the frames open; c, c, are eyes at the lower ends of the arms, through which the straight part of a ring d, passes. These eyes are circular, with a small notch cut in each; and upon the upper side of the straight part of the ring d, there are small teeth, which, when the ring is raised up, are enabled to slide through the notches of the eyes, and thereby allow the frames to be extended; but when the ring hangs down, as in the figure, the teeth bearing against the sides of the eyes, confine the frames at any distance apart to which it may be desired to expand the collar, to suit the neck of the horse.

Another modification of the lower connecting parts of the framing, is shewn at fig. 2; in which, instead of the ring d, a straight bar is employed, sliding into sockets at the ends of the frames; by means of which, the collar may be opened or closed to any extent within the length of the bar.

The patentee states, that he claims, firstly,-applying a frame, and dispensing with the ordinary moveable hames; and secondly,-applying a frame when the collar is made to open for the purpose of extending or contracting it.-[Inrolled in the Inrolment Office, March, 1840.]

TO LUKE HEBERT, of Paternoster-row, in the city of London, for improvements in horse collars,-being a communication from a foreigner, residing abroad.— [Sealed 9th May, 1836.]

THESE improvements are designed to afford the means of expanding and contracting a collar, so that it may be made to fit the neck of any horse, whether large or small.
