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 feet, 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, &e., as the substitution of it for leather in pump buckets, valves, &c. These buckets can be had of any size or thickness WITHOUT SEAM or 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 anticipate 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 piecès, &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.

The POLICIES are INDEFEASIBLE and INDISPUTABLE, which renders them certain as Family provisions, and negotiable instruments of security for pecuniary transactions.

To remove all doubt upon this important subject, at present, and for all future time, the following clause has been inserted in the Deed of Incorporation of the Company; Clause 84.

"That every Policy issued by the Company shall be indefeasible and indisputable, and that the fact of issuing the same shall be conclusive evidence of the validity of the Policy, and it shall not be lawful for the Company to delay payment of the money assured thereby on the ground of any error, mistake or omission, however important, made by or on the part of the person or persons effecting such Assurance, and that on the contrary, the amount so assured shall be paid at the time stipulated by the Policy, as if so much error, mistake or omission had been made or discovered."

The whole Profits belonging to the Assured.

Important to Railway Companies, &c.

LEWTHWAITE begs respectfully to inform

J. the Directors of Railway and other Companies,

that he has

INVENTED A MACHINE

FOR

PRINTING AND NUMBERING RAILWAY AND OTHER TICKETS.

And will shortly be ready to supply them with Tickets or Machines.

J. L. has great pleasure and confidence in making this invention public, as, from the distinctness and accuracy of its work, it must prove invaluable to all who regard these objects as of primary importance. It is simple of construction, accurate in execution, throws off 12,000 or 15,000 impressions per hour, occupies but little space, and a boy eight years of age may work it with ease.

N.B.-Samples of the Tickets forwarded immediately on application, and to be seen at the Mechanics' Magazine Office, 166, Fleet-street, London.

THE DISC ENGINE, AS IMPROVED BY MR. BISHOPP.

THE DISC ENGINE, AS IMPROVED BY MR. BISHOPP.

[When noticing, recently, the disc engine erected at the Times Printing-office, and its admirable performances there (as well as elsewhere), we promised to give, on some future occasion, an explanation of those improvements made in it by Mr. Bishopp, by which he has redeemed it from a state of half oblivion and no inconsiderable odium, and raised it once more to a foremost place among the mechanical wonders of the day, Mr. Bishopp himself has since kindly favoured us with an account of his two improved disc engines, which are now in course of construction, for drainage purposes, by the eminent firm of Messrs, Whitworth and Co., of Manchester; and, by giving insertion to it, we shall no doubt render a much more acceptable service to our readers than we could do by any description or remarks of our own.-ED. M. M.]

The accompanying engravings represent a 57-inch disc pump and a 21-inch disc engine, constructed by Messrs. J. Whitworth and Co., of Manchester, on Mr. G. D. Bishopp's improved plan, and now in course of being erected at Patrington, near Hull, to drain an estate under the superintendence of Josiah Parkes, Esq., C. E.

The quantity of water to be lifted will be 12 tons per minute, and the greatest height of the lift will be seven feet.

Fig. 1, represents a side elevation; fig. 2, a plan; and fig. 3, an end view of the engine and pump. The pump, A, is constructed with plain cones and a plain diso; and in order to keep the disc in contact with the cones, the diagonal shaft, B, is driven by a drag-link, C, which takes hold of a pin fixed in the spurwheel, E; the distance of the centre of the pin from the centre, S, being greater than the radius of the circle described by the end of the diagonal shaft, B.

The spur-wheel, E, is driven by the pinion, F, on the engine-shaft, G; and the relative speeds of the engine and pump are five to one.

The pump has no valves, and the stream delivered is continuous, and not intermittent, although neither a standpipe nor an air-vessel is employed. The suction-pipe, H, descends into a well, I,

into which the water flows through a culvert, D, from the land reservoir. The culvert, N, leads into a drain, called the Winestead Drain, which leads to the sea, and has a sluice-gate at the end of it, to be opened in summer for the purpose of irrigating the land. The delivery-pipe, K, descends into another well, L, and from the latter a culvert (similar to N) leads into the Winestead Drain, Consequently, the level of the water in the well, I, will always be the same as that in the land reservoir, and the level of the water in the well, L, will be the same as that in the Winestead Drain.

As the stream delivered by the pump is continuous, the water in the deliverypipe, K, above the level of the water in the well, L, will balance so much of the pressure of the atmosphere as is due to that height; or, in other words, it will balance an equal column of water in the suction-pipe, H. Therefore, the work done by the engine will never be more than that due to the difference of levels in the two wells, which will sometimes be no more than twelve inches, and at other times will be as much as seven feet.

With an ordinary pump, or a scoopwheel, which is usually employed for raising large volumes of water at a low lift, the power exerted would always be equal to that required to raise the water to a given height; viz., that of the highest level of water ever in the Winestead Drain, or some complicated contrivance must be employed to avoid doing so.

The engine (M) is an 8-horse power high-pressure disc engine, with expansive gearing cutting, off at half-stroke, and is constructed with the improvements lately patented by Mr. Bishopp, who has been engaged for some few years past by the patentees of the disc-engine to superintend the construction of their engines. These improvements may be thus briefly indicated:

with Instead of using a disc and cones, teeth or projections cast on them, a plain disc is employed, having parallel sides, and each of the two cones has twenty-two parallel and deep grooves placed in it, into which are fitted slips of metal. These slips project a sufficient distance above the surface of the cones for the disc to touch three of them at once, and
