Joseph Deeley, of the London and Newport Iron Works, Newport, Monmouthshire, RESPECTFULLY recommends to the notice of the Public his Patent Foundry Furnace, which has been effectually tested and is now in constant use at the above works, where it may be inspected by all persons interested. This Furnace operates without the aid of any motive power to impel the air. An immense saving is the consequence, both in erecting and working. One-third of the coke usually required is more than sufficient; a loss of only twenty-two pounds to the ton being sustained in smelting. The Iron melted in this Furnace also undergoes an extraordinary improvement in quality.-Scotch Pig and Scrap being returned equal to the best cold blast in point of strength, and capable of being chipped or filed with the greatest facility. Foundries using the Furnace may exist in the most densely populated cities, without causing the least nuisance, all smoke, dust, and noise being entirely avoided. The Foreign Patent Rights of the above are for disposal, affording Capitalists the most favourable opportunity for profitable investment.-Apply to the Patentee as above. To Engineers, Machinists, and others.-Plant Machinery and Tools; and also the Lease of the Factory, by Messrs. TOPPIN, HURFORD, and Co. (successors to Mr. W. W. Simpson), on the premises at Chariton, near Woolwich, on WEDNESDAY, October 31, at 11 o'clock, by order of the Mortgagees, FOURTEEN TURNING LATHES, a 5-horse power non-condensing patent rotary steam-engine, a 6feet lathe wheel by "Holtzapffel," 3 hydraulic presses, drilling, chopping, and punching machines, portable forges, wrought-iron windlass, heading press, vices, new files, turning and drilling tools, grindstone, benches, scales, steel bars, riveting wire, ladders, trucks, anvils, force pumps, stoves, packing-cases, iron safe, dial, olhce fittings, old iron, and other effects.-May be viewed two days preceding the day of sale, and catalogues had of Messrs. Sewell and Fox, solicitors, 51, Old Broad-street; on the premises; and of the auctioneers, 13, Bucklersbury, London. PATENTEES AND INVENTORS desirous of Selling the Whole or Shares of their Patents or Inventions, may be introduced to Respectable Capitalists, and rely upon an equitable arrangement being made between them, by MR. EDWARD PALMER, Auctioneer, Estate and Patent Agent, 20, Change-Alley, Cornhill. GUTTA PERCHA. Wharf Road, City Road, London. IT cannot now be doubted even by the most sceptical, but that GUTTA PERCHA must henceforward be regarded as one of the blessings of a gracious Providence, inasmuch as it affords a sure and certain protection from cold and damp leet, and thus tends to protect the body from disease and premature death. Gutta Percha Soles keep the feet WARM IN COLD, AND DRY IN WET WEATHER. They are much more durable than leather and also cheaper. These soles may be steeped for MONTHS TOGETHER in cold water, and when taken out will be found as firm and dry as when first put in. Gutta Percha Tubing, Being so extraordinary a conductor of sound, is used as speaking tubes in mines, manufactories, hotels, warehouses, &c. This tubing may also be applied in Churches and Chapels, for the purpose of enabling deaf persons to listen to the sermon, &c. For conveying messages from one room to another, or from the mast-head to the deck of a vessel, it is invaluable. For greater distances the newly-invented ElectricTelegraph Wire covered with Gutta Percha is strongly recommended. Mill Bands. The increasing demand for the Gutta Percha strapping for driving bands, lathe-straps, &c., fully justifies the strong recommendations they have everywhere received. Gutta Percha Pump Buckets, Clacks, &c. Few applications of Gutta Percha appear likely to be of such extensive use to manufacturers, engineers, &c., as the substitution of it for leather in pump buckets, valves, &c. These buckets can be had of any size or thickness WITHOUT SEAM OF JOINT, and as cold water will never soften them, they seldom need any repair. Gutta Percha Picture Frames. The Gutta Percha Company having supplied HER MAJESTY THE QUEEN with several elaborate Gutta Percha Picture Frames for Buckingham Palace, which have been highly approved by the Royal Family, fully auticipate a great demand for frames from the nobility throughout the country. In order that the picture-frame makers may not be injured, the Company will supply the trade with the mouldings, corner and centre pieces, &c., and allow them to MAKE UP the frames. Pattern books for the trade are now ready. Gutta Percha soles, solution, inkstands, card-trays, medallions, picture-frames, brackets, mouldings, window-blind cord, soap-dishes, tap-ferrules, cornices, vases, fire-buckets, bowls, pen-trays, stethoscopes, thin lining, thread, flower-pots, ear-trumpets, &c., &c., manufactured at the Company's Works, Wharfroad, City-road, London; and sold by their Wholesale dealers in town or country.

To Engineers and Boiler THE BIRMINGHAM PATENT IRON TUBE Central Patent Agency Office, IT Brussels. has long been the opinion of many Scientific Men, Inventors and Manufacturers, that it would be of the greatest utility to establish in some central part of Europe, a Consulting Agency Office, directed by an experienced Engineer, who might assist Inventors by his experience and advice, to procure Patents (Brevets) and prepare the requisite papers, and to promote generally the interests of his clients. Influenced by this prevailing feeling on the subject, M. JOB DIXON, consulting Engineer, Knight of the Netherlands Lion, &c., has, at the solicitation of numerous scientific friends in England and the Continent, opened a Patent Agency Office at Brussels, Rue d'Artifice, 84, bis, Boulevard de Waterloo, Where orders will be received for the Procuration of Patents of Invention for the various States of Europe, and the United States of America; and where Mr. DIXON may be personally advised with on all matters relating to the Securing of Patents for Inventions or to the working of the same. Persons favouring Mr. DIXON with their com mands, may rely on the most judicious care, confidence, and dispatch. N.B. All letters or packages to be addressed postpaid.

Specification enrolled September 14, 1849. Patentee, Alexander Swan, of Kircaldy, Manufacturer.) I. MR. SWAN's improvements have, firstly, for their object, the economizing of fuel in the generation of steam, in the evaporation of fluids, and in the distillation of coal and other like substances. Two of his exemplifications will suffice to show the general system on which he proceeds : Figs. 1, 2, 3, and 4 exemplify the application of these improvements to an ordinary steam boiler. Fig. 1 is a longitudinal section of the boiler, furnace, and appendages. Fig. 2 is a cross section on the line, ab, of fig. 1; and fig. 3 is an end elevation. A, is the furnace; B, the furnace door; C, the ash-pit; D, a small cylindrical boiler, which occupies a place in the interior of the furnace, and is prolonged backwards to E, between which and the furnace, A, it forms the core around which a spiral flue, FF, is constructed. The heated products of combustion arising from the furnace are thus made to traverse over nearly the whole of the exterior surface of the boiler, D, before arriving at the flue, G, where they come in contact with the exterior surface of the boiler, H, and ultimately pass into the chimney by the internal flues, J. By this arrangement, the greater portion of the heat generated in the furnace is absorbed by the boiler and its contents before the gases enter the chimney. KK, are pipes which connect the boilers, D and H, together, and through which the steam and water have free course to circulate. L is an apparatus for regulating the draught through the chimney, according to the pressure of the steam inside the boiler. When the pressure increases, through a too great intensity of fire in the furnace, or from other causes, the regulating apparatus closes the damper, M, and slackens the fire, while, on the contrary, a decrease of pressure of the steam causes the regulator to open the damper. A view of this regulating apparatus, partly in section, is given on an enlarged scale in fig. 4. N, is an upright cylinder fixed on the top of the pipe, O, which last has free communication with the boiler; P, is a metal plunger, which fits loosely into the cylinder, N. At the bottom this plunger rests upon a diaphragm, O2, of vulcanized caoutchouc or other suitable elastic substance capable of resisting the force of the steam, and at top it carries a rack, Q, which takes into a pinion, R, affixed to the shaft of a grooved pulley, S. The damper, M, is suspended from a chain on the pulley, S, and counterpoised by a weight, T, upon the opposite side of the Fig. 5 represents this system of heating The lees are introduced through a pipe at L. MM, are the handles of the scrapers or tube cleaners. Fig. 6 is a longitudinal section, and fig. 7 is a cross section of a tube for evaporating lees. It is fitted inside with a moveable division-plate AAA, with level flanges on its surface, as represented in section. The lees are admitted at B, circulate between the flauges and escape at C, in a The heat is to be applied recovered state. to the external surface of the tube by means of a furnace and spiral flue, as has been described in reference to fig. 5. II. Mr. Swan shows, secondly, how his spiral flue system may be advantageously applied to the heating of air for drying purposes; such as the drying of yarn cloth, paper, grain, &c., and also to heating of houses.
