NORTH GALLERY, AND WITH CLASSES 5 & 6. 137 SAMPSON, THOMAS, Landore, near Swansea, Glamorganshire-Inventor. A high-pressure steam-boiler, with self-feeding apparatus and still, for generating steam and for chemical purposes in general. The water is admitted into the boiler without pumping, by simply moving a hand, similar to the hand of a clock, one quarter of a revolution. A retort for generating gas, or for chemical purposes, with a revolving agitator to keep the charge in motion. A condenser for gas, so constructed that by opening one joint, the whole of the condensing surface is rendered visible, and is within reach, for the purposes of cleansing: the condensed liquor is discharged at five different pipes, so that five different qualities are produced by the same operation. 139 VAUGHAN, WILLIAM, Maidstone-Inventor. Machine to facilitate the construction of marble, stone, slate, or other chimney-pieces by economising labour, and insuring accuracy in the work. The present mode of adjusting the several pieces of a chimney-piece jamb, is, by the use of wooden gauges, prepared to the various dimensions required, and by squaring up the sides (inside-slip and outground) from the face of the jamb, then temporarily fixing them with square blocks against each outside, till the whole is secured with plaster of Paris and pieces of stone fixed inside the jamb. For every jamb the same operation has to be performed. In this machine provision is made for constructing jambs, varying from 6 inches to 14 inches in width, by moveable standards fitted accurately in the grooves of the brass plates which are fixed flush with the face of the slate. These standards render the use of a square unnecessary. The graduated plates supersede the necessity of a rule, and the triangular brass gauge not only dispenses with the use of all other gauges, but ensures great accuracy. The transverse and longitudinal stops being fixed to the required heights above the top of the front of the jamb, and the ends of the side pieces being placed against them, exact provision is made for the depth of the capping and frieze to be afterwards fixed thereon. For the construction of the jamb to the opposite hand, it is only necessary that the longitudinal stop should be placed as much below the centre line on the graduated plate as it now is above. The other part of the machine remaining unaltered, both jambs will necessarily have the same form and dimensions. When several chimney-pieces of the same dimensions are required (a common circumstance), the whole number of jambs may be put together without moving any other part of the machine than the longitudinal stop once; thus ensuring, not only the same form in them all, but effecting an important saving of time. The box gauge, which may be applied to any width of chimney jamb fitted within the standards, presses the inside slip and outground against the standards, thus preventing any derangement of the several pieces, whilst they are being fixed together with pieces of stone and plaster of Paris.

By affording facility for the rapid and entire discharge of its contents, this invention proposes to prevent the accumulation of filth and sediment in house cisterns; and, by conducting the waste and discharge pipes into the house drain, both to preclude local dampness arising from overflow, and effectually to cleanse the latter by constant flushing. Though the cylindrical form of cistern with a conical base is, in all cases, preferable, the principle of this invention is equally applicable to any other form which may be topically convenient, and to any material used in the construction of cisterns. 146 QUINCEY, HARCOURT, 82 Hatton Garden— Working model of two revolving iron safety shutters, with patent convex laths (one fixed above and one under the window), with improved gearing; and of a patent corrugated office blind of perforated metal.

Universal fire-escape. The novelty of the plan is stated to be that of passing persons from the window of the house on fire to the near window of the neighbour's house adjoining, in a direct horizontal line, right or left, in lieu of lowering them down as in the ordinary way. This is accomplished by having bracket-hooks of a peculiar construction, projecting about 12 inches from the face of the brickwork, permanently fixed to the front of the house at the uppermost floor, by passing the end or stem of the hook through the brickwork, and screwing it up tight by plates and NORTH GALLERY, AND WITH CLASSES 5 & 6. WILKINS, WILLIAM CRANE, 24 Long Acre, and nuts inside. By the assistance of the neighbour at the 157 Finch and Willey's patent safety railway wheel. The peculiarity of this wheel consists in the rim of the skeleton or inner wheel being firmly imbedded in a dovetailed recess in the tire, throughout its whole circumference, rendering all other fastening, as bolts, &c., unnecessary, and preventing the possibility of accident from the breakage or throwing off of the tire. The tire can also be worn much thinner than ordinary. Improved flooring cramp.

Model of emigrants' house, about one-fourth full size, made of Morewood and Rogers' patent galvanised tinned iron, corrugated. The full size weighs about half a ton, and can be packed in two cases. When once seen put together, it may be erected by two persons in as many days. Furniture of the house, made chiefly of the same mate Fig. 1. Wilkins and Letourneau's Catadioptric Apparatus. That appearance of light, called short eclipses, has hitherto been obtained by the following arrangements:- NOBTH GALLERY, AND WITH CLASSES 5 & 6. An apparatus for a fixed light being provided, composed of a central cylinder and two zones of catadioptric rings, forming a cupola and lower part, a certain number of lenses are arranged at equal distances from each other, placed upon an exterior moveable frame, making its revolution around the apparatus in a given period. These lenses, composed of vertical prisms, are of the same altitude as the cylinder, and the radius of their curves is in opposite directions to those of the cylinder, in such a manner that at their passing they converge into a parallel pencil of light; all the divergent rays, emitted horizontally from the cylinder, producing a brilliant effect, like that obtained by the use of annular lenses at the revolving lighthouses. The first improvement exhibited has a special reference to the light, and produces a considerable increase in its power, whilst the simplicity of the optical arrangements is also regarded. It consists, firstly, in completely dispensing with the moveable central cylindrical lenses. Secondly, it replaces these by a single revolving cylinder, composed of four annular lenses, and four lenses of a fixed light introduced between them; but the number of each varying according to the succession of flashes to be produced in the period of revolution. The second improvement, of which already some applications that have been made serve to show the importance, consists in a new method of arranging the revolving part, experience having shown that the arrangements at present in use are very faulty. A short time is sufficient for the action of the friction rollers, revolving on two parallel planes, to produce, by a succession of cuttings, a sufficiently deep groove to destroy the regularity of the rotatory movement. To obviate this great inconvenience, the friction rollers are so placed and fitted on an iron axis, with regulating screws and traversing between two bevilled surfaces, that when an indentation is made in one place, they can be adjusted to another part of the plates which is not so worn. The third improvement produces the result of an increase of the power of the flashes in revolving lighthouse apparatus, to double what has been obtained hitherto. By means of lenses of vertical prisms, placed in the prolongations of the central annular lenses, the divergent rays emerging from the catadioptric zone are brought into a straight line, and a coincidence of the three flashes is obtained. The whole of the prisms, lenses, and zones are mounted with strength and simplicity, accurately ground and polished to the correct curves, according to their respective positions, so as to properly develop this beautiful system of "Fresnel." The glass of which they are composed is of the clearest crystal colour, and free from that green hue which so materially reduces the power of the light, and is considered objectionable for apparatus of this kind. The lamp, by which the apparatus is to be lighted, consists of a concentric burner with four circular wicks, attached to a lamp of simple construction, the oil being forced up to the burner by atmospheric pressure only, so that there are no delicate pumps or machinery to become deranged. Improved lantern and revolving apparatus for a lightvessel, represented in fig. 2. The principal improvement consists, in constructing the machinery to work beneath the deck, instead of in the lantern as formerly. A vertical rod, working in metal bearings, is attached to the mast, with a large gun-metal pinion fixed to the top of the rod, at the height to which it is necessary to hoist the lantern, wherein a train of cog-wheels are placed to connect with the pinion, and communicate the motion obtained therefrom to the traversing apparatus that supports the lamps and reflectors. The advantages of this arrangement are, that the lanterns can be made much lighter, the rolling of the vessel caused by so great a weight at the mast-head is greatly diminished, and the machinery being more under control and better protected, works with greater regularity and precision. An idea of the utility of these improvements may be gained by reflecting that the situations in which the light-vessels are placed, are at all times difficult of access, NORTH GALLERY, AND WITH CLASSES 5 & 6. duced a complete revolution in the apparatus for floating lights, and enabled the beautiful Argand lamps, with parabolic reflectors, to be used instead of the old lamps with smoky flat wicks.

Model of the railway-bridge, crossing Westminster bridge road. (South Western Railway.) 178 MOORSOм, W. S., Captain, 17 Great George Street, Westminster-Designer and Superintendent. Prize design for the great bridge over the Rhine, proposed by Prussian Government to be erected at Cologne. The Piers are to be of stone, and the arches of wrought (If erected at English prices, about one-fifth less). The principle of this bridge is that of the trellis or lattice beam combined with the arch. The arrangement of the cross bracing is novel and peculiar, and affords separate spaces for the great highway, the railway, and the footway. The lifting-arch is to be worked by water power; the water being contained in tanks on the tops of the towers, and being elevated to those positions by tide-wheels of peculiar construction, placed below the possibility of contact with ice, and worked by the river current. The arches are believed to be the largest in the world, proposed of rigid construction (not suspension), and calculated for the passage of locomotive engines at speed, and of artillery at the gallop. Railway viaduct over the river Nore, near Kilkenny, Ireland. The arch is constructed of timber, and the piers of stone. Length of the bridge and approaches 428 feet.

Design for a timber viaduct of great span, suitable for railway or other purposes. Its object is to unite great strength with simplicity; the beams forming it, are interwoven like basket-work, and the greater the stress thrown upon it, the more rigid it becomes. The same principle may be adapted to large roofs without the use of crossties, since the outward thrust upon the walls would be but small.
