part of the tube with wood, or other suitable substance. Instead also of the brushes being circular, they may be made flat, and the spun glass be secured within flat tubes or between flat plates of glass, placed either parallel to each other or at any suitable angle, and closed at the ends by the blowpipe or any other suitable means.

His

A sixth improvement relates to brushes for cleaning decanters and other bottles. Two years ago Mr. Cole invented a brush for cleaning decanters, and introduced it to the trade under the name of "The Nonpareil Water Bottle and Decanter Brush." The brush answered well in most instances, but it was found too thick to pass the necks of many of the more modern decanters. It seemed at first that this defect could not be overcome without endangering the strength and efficiency of the brush, but Mr. Cole has now discovered that it can be accomplished with safety by the following method. decanter brush, as originally made, was formed on a piece of beech wood, 12 inches long and square. For eight inches of the length the wood was turned round to serve as the handle, and to the remaining square piece of 4 inches he attached the brush. The holes for the bristles were bored down two sides of the square and at the end; and the other two sides were excavated to form a backway to the holes, through which to introduce the wire by which the bristles were to be drawn in. After the brush was made, the excavations were filled up with putty or cement. The width of these excavations was about of an inch, and if they could be dispensed with there would be of an inch in diameter gained, which is considerable in so small a space as the neck of a decanter. Now Mr. Cole dispenses with them in this way. Instead of making the brush on one piece of wood, the makes the sides of the brush in two parts, that is to say on separate pieces of wood, and then fits them together back to back, and pins them together with metal pins. Beech wood can be used as in the original brush, but he prefers for this new arrangement, hard wood or bone, as having more strength and closeness of grain. The slips of wood or bone may be a little longer than is necessary for the brush part, and when united by the pins the extra length may be turned, so as to fit in a stem of beech for a handle; or the slips may be of the full length requisite, that is about 12 inches, and united by pins the whole length, which last mode the patentee thinks both the best and cheap

tube, and then to attach the tube to the brush. The second is to sew two pieces of plush together in such a manner, that they shall present two faces with the grain of each running in the same direction. This he inserts between the slips at the end of the brush, when pinning the two parts together, taking care to insert it so that the grain of the plush inclines towards the brush. The effect of this arrangement is, that in whatever way the brush is worked in the decanter, the plush presents its opposing grain to any surface it passes over, and consequently acts like a brush. The third method is to attach a flannel bag with a few shot enclosed, to the top of the brush. A flannel bag attached to a bent rod of wire is frequently used alone for cleaning decanters, but it has never been used in combination with brushes of the kind herein described.

The seventh and last improvement comprehended under the present patent relates to brushes for cleaning cruets and other small bottles, which the patentee makes in the following manner. He takes a slip of boxwood or bone, about 4 inches long, of an inch wide, and thick, and beginning at one end, he bores a row of holes about 2 inches long, boring the first hole in a sloping direction, so as to throw the bristles over the end of the wood, and gradually at each hole working to an upright. He then forms a groove at the back of the holes for the reception of the wire; the bristle is then drawn in, and cut off at any suitable height, and the wire covered over with cement, sealing-wax, or other suitable material, when the brush is complete.

HENRY JUBBER OF OXFORD, CONFECTIONER, for certain Improvements in Kitchen Ranges and Apparatus for Cooking.-Enrolment Office, Dec. 2, 1841.

The peculiarity in this new kitchen range consists chiefly in two things,-first, in the spits being worked vertically, two on each side of a fire, and each spit carrying four joints, so that sixteen joints may be roasting at one and the same time; and, secondly, in shutting up the fire on all sides while the operation of "roasting" is going on, whereby "the entire heat" is said to be rendered "available." When it is desired to ascertain the progress of the roasting, or to baste the meat, or feed the fire, there are doors which may be readily opened for each purpose and then shut.

The inventor of these patent improvements in roasting, has evidently yet to learn what roasting is. He could not by the process he describes, with closed doors, roast at all, or produce any thing but baked meats. Neither is it likely to be generally regarded as an improvement, either in roasting or baking, to have four different joints dripping

one into the other, and intermingling their odours, so that when dished, the lamb shall have the flavour of beef, the mutton of pork, and vice versa : or, what is perhaps still more probable, a flavour so odiously compounded, as to smack "neither of flesh, fish, fowl, nor yet good red herring."

JAMES CHESTERMAN, OF SHEFFIELD, MERCHANT, AND JOHN BOTTOM, ALSO OF SHEFFIELD, MACHINIST, for certain improvements in tapes for measuring, and in the boxes for containing the same.-Rolls Chapel Office, January 11, 1842.

The first of these improvements (which are four in number) consists in partly or wholly forming the tape of metal. This may be done in various ways, but the patentees prefer introducing any convenient number of fine copper or silver wires in the warp of the tape, which are equally distributed throughout the width of the tape, one at or near each selvage, and the others at equal distances between them. By these means, at a very trifling expense, the tape is made more durable, and prevented from stretching."

[ocr errors]

The second improvement relates to the boxes for containing the tapes, and consists in an improvement upon a former patent granted to J. Chesterman, (July 14, 1829.) Formerly, only one spring was used, and when required for long lengths, multiplying wheels and pinions were added; but, instead of the wheel-work, the patentee now employs an extra spring or springs, which are always constant and unvarying in their action, and not so liable to derangement.

The third improvement consists in applying the improved spring tape measure with a single or double spring, or any other tape measure of whatever description, to straight rules, sliding rules, or any other rule or instrument requiring such an addition. By way of example a drawing is given, which represents a method of applying a single spring tape measure to a 2 feet folding rule, so as to make it measure 6 feet when opened and the tape is drawn out-one spring being quite sufficient for this length.

The fourth and last improvement consists in the application of one, two, or more revolving plates of metal to the improved tape boxes, or boxes of the ordinary construction. These plates may be lettered and figured as may be required. In a drawing which illustrates this part of the specification, an almanac or indicator for ascertaining the day of the week upon which any day of the month will fall, is shown, as applied to a tape box; but it is frankly observed that any other table or tables, may be employed with equal advantage. Sometimes in the place of any table, almanac, or other printed information, the patentees substitute a plain sheet of paper, asses' skin, or other material; upon which,

memoranda or calculations may be made and effaced.

The claim is to, "1st, the method of making tapes for measuring; consisting wholly of metal, or partly so, by the introduction of metal wires, open wire fabric, or plates of metal. 2. The construction of spring tapes, with two or more springs, for the purpose of obtaining sufficient power to wind up a long length of tape, instead of employing a single spring with wheel-work, as described in the specification of the said James Chesterman's former patent of July 14, 1829. 3rd. The adaptation or application of tape measures to straight rules, either jointed or otherwise, and also to other articles or instruments requiring such addition. 4th. The application of calculating tables, or plain sheets for calculating to tape boxes of any construction whatever, in the manner set forth and decribed."

The first claim is good; the second doubtful; the third and fourth preposterous.

ANTOINE JEAN FRANCOIS CLAUDET, OF HIGH HOLBORN, GLASS MERCHANT, for certain improvements in the process or means of an apparatus for obtaining images or representations of nature or art. Petty Bag Office, June 18, 1841.

The present improvements in Mr. Claudet's well-known process are five in number, and all apparently of importance.

The first consists in giving the front of the camera obscura, an aperture large enough to admit object glasses of various foci, so as to enable the operator to work either on large or small plates, and obtain images either of near or distant objects; and in affixing these various arrangements of glasses to sliding boards, which may be moved in front of the camera, or withdrawn, at plea

sure.

The second consists in substituting for the detached mercury-box, ordinarily employed, a cup of mercury placed within the camera, and heated by a spirit lamp till the mercurial vapours rise and fill the camera. The light and mercury are made thus to act simultaneously on the plate, whereby a more intense and perfect image is obtained. In the side of the camera there is an eye-hole, covered with red or orange-coloured glass, through which the operator may watch the process, and be thus enabled to withdraw the plate the instant the proper effect is produced.

The third consists in placing immediately behind the sitter for a portrait, painted backgrounds or scenes, representing landscapes, interiors of apartments, &c., which, being thus brought within the range of the Daguerreotype apparatus, are transferred to the plate, as well as the likeness of the sitter.

The fourth consists in the employment, in

the absence of daylight, of an artificial light, produced either from the combustion of coal, promoted by a jet of oxygen gas, or from combustible gases and carburetted liquids burning together with oxygen; or from a solid refractory body suspended in a jet of inflammable gas, &c. Care must be taken that the burner is fixed exactly in the axis of the reflecting mirror, or that the greatest light falls on the centre of the curve.

The fifth and last improvement consists in performing the whole process in a lighted room, instead of in the dark, as has been hitherto the case. A white light must, however, be avoided, and screens of red, orange, green, or yellow, are therefore employed. Of these colours, red is preferred, as having the least injurious effect on the plates.

ADOLPHUS FOURMENT, OF MUSEUM-St., ENGINEER, for Improvements in Castors for Cabinet Furniture and other purposes.— Enrolment Office, June 21.

These inprovements consist, "First, In a ball and socket forming the castor without anti-friction rollers of any kind, but with three points of contact cast or otherwise raised within the socket, which rest on the ball, and enable it to turn freely while supporting the superincumbent weight whatever it may be. Secondly, in case-hardening the said ball and socket either or both, as circumstances may require, where any extraordinary quantity of friction is anticipated."

No claim is made.

The Late Solar Eclipse.-We have been indulged with the perusal of a private letter from that excellent astronomer F. Baily, Esq., giving an account of this superb phenomenon, as witnessed by himself at Pavia, over which town the line of central darkness exactly passed. The appearances were every way extraordinary, unexpected, and most singular. At the moment when the total obscuration commenced, a brilliant crown of glory encircled the moon, like the "Aureola," which Catholic painters append to their saints. Suddenly, from the border of the black and labouring moon, thus singularly enshrined, burst forth at three distinct points, within the aureola, purple or lilac flames! visible to every eye. At this moment, from the whole assembled population of the town, a simultaneous and deafening shout broke forth. A similar manifestation of popular feeling is recorded at Milan, occasioned by the selfsame astonishing spectacle, accompanied in the latter instance with a general "Huzzah! vivent les astronomes !” The eclipse was also viewed from the Superga, near Turin, by our Astroneer Royal, Mr. Airy, apparently under less favourable circumstances. We have yet heard of no astronomer witnessing from a great elevation in the Alps the shadow striding from peak to peak, or blotting in succession the fair fields of North Italy. Such an exhibition must have been perhaps the sublimest which the eye of man can ever witness as a mere physical phenomenon.-The Athenæum.
