ing. One of these creels is to be placed at each side of the beaming-apparatus, the main framing of which is represented at 1, 1, 7; the threads or ends from the said creels (a portion only of which are shewn in the figures) pass through the reeds m, m, to the healds n, n, which are mounted with winches and ratchet-wheels o, o, for the purpose of raising the same when taking the “lease or cross-shed. p, p, are rollers, over which the yarn passes, and thence under the roller q, q1, and upwards through the reed r, r, over the rollers s, s, to the beam t. The beam t, is caused to revolve by means of a strap, connected to the stud u, fixed in the disc v, which is actuated in the following manner:-Rotary motion is to be communicated to the main driving-shaft w, by means of a strap passing around the pulley x, and by means of the bevil-wheels y, y, to the upright shaft z. This shaft carries the conical pulley 1, which drives a similar pulley 2, by means of a strap. The pulley 2, is mounted upon a shaft 3, at the upper end of which is a worm 4, driving a worm-wheel 5, keyed upon a short shaft, (working in the socket 6,) upon which the disc v, is fixed. The proper differential speed, so as to take up a uniform quantity of yarn as the diameter of the yarn-beam increases, is communicated to the said beam as follows:-7, is an upright screwed shaft, working through a nut in the boss of the forked strap-guide 8; which shaft is caused to revolve, and thus alter the position of the strap upon the conical pulleys 1, and 2, by means of a worm, upon the end of the roller q, taking into a worm-wheel upon the shaft 7 this shaft may also be turned by means of the handle thereon. A reciprocating motion is given to the reed r, r, for the more complete filling of the yarn-beam, by the following means:-9, is a small pinion, attached to the boss. of the disc v, driving a wheel 10, having upon its boss a small disc 11, placed at an angle of about 70° to its axis. The circumference of this disc 11, works in the forked end of a lever 12, which works upon a stud 13, and carries, at its other end, the reed r, r: the position of the stud may be adjusted by means of the handle upon the screw 14, which works through a nut in the stud 13. Upon the end of the roller q1, a bevil-wheel is keyed, which gears into a bevil-wheel upon

a small upright shaft 15. This shaft carries a worm, which works into a worm-wheel, for measuring the yarn, and giving an alarm when the beam is full, by ringing the bell 16.

Fig. 6, is a plan or horizontal view of the measuring and marking apparatus. 17, 17, are two small rollers, geared to the worm-wheel aforesaid, and working in a trough 18, containing color; the lower one being partially immersed in the color in the trough, and furnishing a sufficient quantity to the upper one. When the yarn-beam is full, and the bell rings, the top of the bell-lever 19, presses a portion of the yarn against the upper roller 17, which imparts to it a patch of color.

Fig. 7, is an elevation, fig. 8, a section, and fig. 9, a plan view of one end of another arrangement of creel, to be used in connection with the winding-on or warping-frame. a, a, is the crecl or frame in which the bobbins b, b, b, are laid horizontally upon pegs or skewers. The threads, being guided by the wires c, c, c, pass over the rollers or pulleys, and through the two combs d, d, over the roller e, to the yarnbeam. The formation of the combs d, d, is best seen in the enlarged view, fig. 10,-every alternate dent being partially closed, and the closed dent of the one being placed opposite to the open dent of the other: the "lease " or cross-shed is taken by raising the combs, by means of the racks and pinions. ff. The creels a, a, are mounted upon hinges g, g, for the purpose of allowing them to open for creeling or piecing-up, and close afterwards. When the yarn has been sized upon the beam, as many of the wet beams as are necessary must be placed in a frame, and the ends of the yarn passed through a comb, similar to that above described (or through a fine reed, with every alternate dent partially closed) for taking the lease or cross-shed,—thence it passes around the greater part of the circumference of a steam-cylinder, and so on to the warping apparatus.

The patentee claims, Firstly, the novel method of sizing the yarn in the cop, upon the bobbin, or upon the beam, by immersion in hot or boiling size. Secondly, the method of drying and winding the yarn, by the bobbins or tubes lying upon or adjacent to a heated cylinder. And, Thirdly,-the

apparatus employed for sizing, and the peculiar construction and form of creels, together with the novel arrangement of mechanism, shewn in the drawings, and above particularly described, to be employed for dressing; that is, drying, winding, and warping yarns, in the manner and for the purpose herein before set forth.-[Inrolled in the Petty Bag Office, August, 1847.]

To PIERRE ANTOINE JOSEPH DUJARDIN, of Lille, in the kingdom of France, doctor of medicine, for improvements in electro-magnetic telegraphic apparatus.-[Sealed 7th October, 1847.]

THIS invention relates, 1stly, to telegraphic apparatus for calling or attracting the notice of attendants, by means of audible signals, previous to making any merely visible signals; 2ndly, to an apparatus for writing or printing despatches or messages on paper, by means of groups of dots of ink or other suitable fluid; 3rdly, to certain arrangements of magnetoelectric machinery or apparatus, for producing the necessary electric currents, in order to cause either or both of the before-mentioned apparatus to perform their operations.

The apparatus for making audible signals, for the purpose of attracting the notice of the attendants to the apparatus, previous to printing any despatches, or otherwise making mere visible signals, is shown at figs. 1, and 2, in Plate XVIII., wherein a, a, is a flat foundation-plate, upon which the various parts of the apparatus are mounted; b, b, is an electromagnet, fixed upon the plate a, and having its ends enveloped with a coil of copper wire, covered with cotton or silk. At the upper end of this electro-magnet two small iron plates c, c, are mounted, in such a manner that they may be turned on their centres, so as to be moved nearer to, or further from each other, as circumstances may require, and for the purpose of regulating the action of the apparatus. d, d, is a long rectangular permanent magnet, constructed of a thin flat piece of steel, and is supported at its centre on a fine pointsuch as a strong sewing needle-which is mounted in the vertical support e. A glass bell or vessel f, similar to an

ordinary drinking glass, is secured, by means of a hole in the centre of its bottom, to a piece of brass g, which is attached to the foundation-plate a, by a screw, as a centre-pin, so as to admit of the vessel ƒ, and the piece of brass y, being moved horizontally on the screw, as a pivot. A cylinder or block of wood h, of the same form and dimensions as the vessel ƒ, is also mounted, in a similar manner, on a piece of brass, and secured to the foundation-plate a, by a pivot, round which it may be moved horizontally, precisely in the same manner as the glass vessel f; so that the vessel f, and the block h, may be moved nearer to, or further from each other, in order to regulate the action of the apparatus.

The apparatus for writing or printing despatches or messages is also shewn at figs. 1, and 2. On the foundationplate a, a, is mounted an ordinary clock-movement i, i, which is actuated, when required, by means of a weight, as shewn. One of the wheels of this clock-movement carries a long pin j,j, which extends out horizontally therefrom, and enters the forked-arm k, of the shaft of the roller m; upon which, a cylinder, covered with paper, to receive the despatches, is placed. This roller m, is mounted horizontally in bearings, as shewn in the figures; one of the ends of its shaft being screwed and made to rest upon a thin blade n, affixed to one of the bearings or supports of the roller; so that, as the roller is made to rotate slowly, by means of the long pin j, j, taking into the forked-arm on the opposite end of the shaft of the roller, it is gradually moved laterally, so as always to present a fresh surface of paper to receive the marks of the pen. 0, 0, is an electro-magnet, placed horizontally on the foundationplate a, a, of the apparatus, and between two fixed bars, which act as guides, and prevent it from moving laterally, but admit of its being moved backwards or forwards, by means of the adjusting screw s.

The electro-magnet o, o, is employed for the purpose of actuating the telegraphic pen p, (seen best in fig. 3, which is a sectional view of this part of the apparatus, drawn upon an enlarged scale). This pen is a lever, composed of iron wire and silver or platinum wire at its marking end; from the fulcrum of the lever a tail-piece depends, for the purpose of

carrying a magnet r, which consists of a long bar, extending in front of the electro-magnet o, o ;-the silver or platinum wire is bent up at its lower end, and flattened out, a notch being cut in the flattened part, for the purpose of receiving a cord, composed of two or more threads of cotton or other fibrous material, which is secured in the notch by winding round it a thread of silk or other suitable material. The pen, thus constructed, is delicately mounted on a pivot or centre-pin at q, so that it may be worked with very little power. The poles of the electro-magnet o, o, when a magnetic power is properly induced in it, and those of the permanent magnet r, are placed opposite to, and in proximity to each other,—that is, the north pole of each magnet is opposite to the north pole of the other, and the south pole of each magnet is opposite to the south pole of the other; so that the electro-magnet will repcl the permanent magnet, and thereby cause the end of the pen to rise. The end of the The end of the pen, when in a quiescent state, remains immersed in the ink-holder p*, so that it is always supplied with ink, and ready for operation at any time. The ink-holder p*, is purposely made small and narrow, in order to prevent a waste of ink by evaporation; and the ink-holder is kept supplied with ink by a pipe, which communicates with a large covered reservoir p**. The paper, upon which the despatches are to be printed or marked, is placed round a cylinder or drum of thin metal, which is slipped on to the roller m, before the latter is placed in the apparatus; and when the paper, round the cylinder on the roller m, is filled with telegraphic signals, it must be removed from the roller, and a second cylinder, provided with paper, placed thereon in its stead;-in order to prevent loss of time, several of these separate and moveable cylinders should be kept charged with paper, so that they may be instantly applied when required. The sheets of paper, which envelope these separate and moveable cylinders, should be long enough to allow their ends slightly to overlap, when wrapped round the cylinder, so that they may be gummed, or otherwise conveniently secured on the cylinders, in such a manner, that when the despatch is completed, and the cylinder removed from the machine, the sheet of paper may be detached there
