THE HE invention consists in this: Instead of making the pin or revolving piece of the improved lock-cock, solid throughout, excepting that part in which the aperture, or channel, is made for the liquor to pass through, they make a cavity in the upper part of the said pin, or revolving-piece between the cross or handle, ring, or other termination made use of for moving the said pin. or revolving-piece and socket, into which the said pin or revolving-piece is fitted, by turning and grinding, and in the cavity so made a lock, having a bolt, is fixed, and likewise the other parts, usually constituting such as operate by means of a bolt; and the said bolt is thrown backwards and forwards, by a motion at right angles to the axis of the pin, by the action of the key, in order that when the said bolt shall be protruded, or shot out of its cell, in the manner of locking, part of the bolt shall stand forward beyond the face of the pin, or revolving piece, and shall enter into a cavity in part of the motionless socket, into which the pin is placed, and shall thereby render the said pin itself motionless, and shall make it impracticable to turn or open the cock, until the bolt shall have been first shot back by means of its key: the whole is so formed that the water-way or course through the cock shall be shut, whenever the said bolt is or shall be protruded in the manner of locking into the said motionless socket, and shall not be capable of being opened until the bolt is withdrawn. It is farther observed, that this improve nent on cocks may be applied to any kind or description of cock, and to the lower as well as, or instead of, to the upper part of the said pin or revolving piece, and the bolt may also, when preferred, be made to shoot or lock into a fixed or motionless piece, proceeding from the vessel or receptacle, in which any liquor or fluid is to be guarded and secured by the said improvement, as well as into a fixed or motionless piece, such as has been described; and that the effect of the last mentioned disposition and application of the bolt with regard to the said vessel or receptacle will be such, as not only to prevent the pin from revolving, with regard or in relation, to the cock itself, but likewise to prevent the said cock, whilst locked, from being unscrewed or drawn out of the vessel. MR. HENRY STUBB's, (PICCADILLY,) for a new invented grand imperial Aulaum, from three to twenty-feet wide, without seam, and to any length or colour, for decorating Rooms, &c. The aulæum is manufactured to the required width, without seams, and to any figure or design. The texture surpasses surperfine cloth, and it approaches in appearance to that of velvet, con. sequently when hung on walls and other places, exhibits a lustre of grandeur and magnificence to the eye of the beholder. It is produced by labour from fine linen and worsted cloth; these are ticles are inseparably attached and firmly incorporated into each other, chiefly by glue, and a small portion of colour, with some driers, of binding and adhesive qualities; the most prominent and that which constitutes the fine face and beauty of the aulæum is a dyed, coloured, or white flock. This being prepared M Mr S. proceeds with the fine linen and worsted cloth, which answers for the back or ground of the aulæum; this fixed in the frame or otherwise suspended in length and breadth, either perpendicular, leaning, or horizontal, it then receives a considerable quantity of glue, together with a small portion of water colour; these two ingredients warmed into a proper consistency of heat, and laid on with a brush, at once form a flexible parchment: the operation of the brush gives lassitude to every thread; the cloth will then expand nearly an inch in every foot; the frames must be then extended in all directions to the tmost extent that the worsted or linen will admit of. When thoroughly hard or dry, another process commences, the parchment undergoes some considerable friction from pumice-stones, all promihent threads and superfluous glue is cleansed off, and then what follows, is a thin coat of colour, as nearly as possible to the colour of the flock in tended for the face of the aulæum: the whole piece of parchment being thinly covered, the flock is put into a sieve and dispersed over it, which still continues strained to a very high pitch, the aulæum is then dressed on the under side, and the flock diffuses and regularly adheres to the composition until finish ed. The aulæum is then dried, by a very strong fire which takes off the effluvia. MR. JOHN ISAAC HAWKINS', (GREAT TITCHFIELD-STREET,) for a certain instrument applicable in Mechanics as a Balance or Equipoise. The nature of this invention, and the manner in which the same is performed, are best described by the drawings attached to the specifications; but perhaps the following account may give the reader some insight into the subject: Instead of a weight commonly used to counter-balance or equipoise a lamp, chandelier, lustre, window-sash, shutter, &c. a steel spring is employed, such as in a spring-clock, is called a main spring, one end of which is attached to a fixed axis, and after coiling this spring around the axis, it is fastened by the other end to a barrel, which has rotation on the axis, as is done in a spring clock. It is known that if a smail weight be sus. pended by a line or chain, to the circumference of the barrel, the barrel will be turned a small distance, but to make it turn_farther, a larger weight is necessary. This spring and barrel is therefore not an equipoise or balance, MONTHLY Mag. No. 212. but requires an addition to constitute it such, for which reason a fusee is fastone end of the barrel: this ened to fusee is so formed, that when the spring is slack, or nearly so, and consequently very weak, the line or chain, which supports the weight, shall hang near the axis; but as by the rotation of the barrel, the spring is wound up and becomes stronger, the said line or chain shali recede upon the fusee from the axis, and thereby procure a greater power of purchase upon the spring, and this in such proportion as that the spring shall support any given weight when hung to the line or chain in all The same effect may be situations. produced by fixing the barrel instead of the axis, and letting the fusee with the axis be turned, instead of the barrel being turned. This machine may be made of iron, brass, steel, or any kind of hard metal, or other hard substance; and in order to bring it into action it must of course be fixed in some situation capable of supporting its own weight, and the weight of the thing to be balanced, and the whole machine may be concealed by any covering or ornament, which In some cases two fancy may suggest. or more machines are placed on one fixed axis, for the purpose of counterbalancing two or more window blinds, or weights of any description. For some purposes it will be requisite to have two or more lines or chains, and consequently to make the fusee with double br multiple grooves; or to have two or more it may be fusees. For other purposes convenient to put the spring and barrel on one axis, and the fusee on another, and to employ a line or chain to connect one going them together, as well as round a cylinder fixed to the fusee, to support the weight, to be counter-balanced. The shape of the fusee must, in all cases, be determined by the va rying power of the spring; and the thickness of the line or chain. ple rule to find this shape is to take account of the actual weight which the spring will support at every half or quarter turn of the barrel, the weight being suspended from the circumference of the barrel. A sim Multiply this weight by the radius of the barrel, and divide the sum by the weight designed to be suspended from the fusee, the quotient will shew the distance at which the line or chain ought to hang from the axis, and consequently will determine the shape of the fusee. In the case of lamps, in which the weight is perpetually varying, a small spring SA 15 is purpose of counter-balancing a weight, and as this has not been done before, the patentee claims the right of doing it in all the various forms which fancy or convenience may dictate, a number of which are shewn in the drawings in the margin of the specification. introduced pressing against the a spring with a snail, or fusee, for the barrel or fusce, or any other couvenient part, to create a degree of fric. tion, to prevent the lamp preponderating when full of oil, and to hinder the counter-balancing spring from being too powerful when the oil is consumed, or the burner removed. The chief advantage of this invention, consists in combining MONTHLY RETROSPECT OF THE FINE ARTS. The Use of all New Prints, Communications of Articles of Intelligence, &c. are requested under COVER to the Care of the Publisher. N Monday the 15th ult, this gal lery was again opened to the public, with the addition of a splendid picture, which the energetic and venerable president of the Royal Academy has just completed, on a large scale, of "Christ healing the Sick in the Temple." It is certainly one of the finest productions of the pictorial art, and reflects additional honour upon the British school. The picture was originally intended to be sent to America; but the directors of the British Institution resolved, upon the recommendation of Sir Thomas Barnard, not to permit such a valuable specimen of genius to be sent out of the country, but to retain it here, that it might be hereafter placed in a national gallery, as a standard by which any works o arts to be admitted there may be judged. The purchase-money of the picture (three thousand guineas) is to be raised by a subscription of sixty of the subscribers to the British Institution, at fifty guineas each, which is now (April) seven-tenths full. Arrangements have been made for the exhibition of this splendid monument of British art in this gallery; for which purpose, the exhibition closed on the 28th of March, and opened again on the 15th ult.. Such of the pictures as have been sold have been delivered to the purchasers, and those which remain unsold are now exhibiting in the middle and north rooms, until the gallery be finally closed for the present season. The south room is devoted to Mr. West's picture, and a few of the largest of the others: those for the premiums, sold or unsold, all remain. It is also proposed to have a print of this picture engraved and published by subscription, and the profits arising there from are to be applied to the increase of the fund lately established by the Institution for annual premiums in historical painting. This liberal and judicious pa tronage, on the part of the British Insti tution, is entitled to much praise; and there is no doubt but that their liberal example will be imitated by all those whose situation in life marks them as the proper patrons of the fine arts. Mr. Fuseli has completed his excellent series of Lectures on Painting, to the students of the Royal Academy; to which he has added, since the last season, much new and important matter. The whole of the lectures this season have been more numerously attended than ever be fore remembered, both by professors, amateurs, and patrons, of art; which is highly satisfactory, and proves the increased influence and extension of love for art among the public. The great exhibition has several times been crowded to the doors, and numbers could not ob tain admission for want of room. On Friday the 22d ult. the second anniversary of that laudable and benevolent institution "The Artists' Fund,” was held at the Freemasons' Tavern, at which a numerous and respectable society of artists and friends to the arts met to celebrate it. The chair was taken by A.W. Devis, esq. The dinner was excellent; and, after a selection of loyal and convivial toasts and sentiments, the chairman gave "The Royal Academy," which called up Mr. West, the president of that royal institution, who returned thanks in its name. "The British Institution," was next given, and received with universal applause. In the interval between each toast, several appropriate songs and 'ees were sung by Messrs. Taylor, Elliott, Doyle, and a young gentleman. In the course of the evening, the chairman made the |
