Specification of the Patent granted to THOMAS Dawson, of James-street, Long Acre, in the Parish of St. Martin in the Fields, in the County of Middlesex, Tin Plateworker; for a Lamp or Lanthorn upon an improved Construction, which may be used with or without a Reflector, for the Convenience of Travelling-Carriages, and other useful Purposes. Dated November 25, 1802.

With a Plate.

To all to whom these presents shall come, &c. Now KNOW YE, that in compliance with the said proviso, I the said Thomas Dawson do hereby declare that my said invention is described in the drawing and description thereof hereunto annexed. In witness whereof, &c.

DESCRIPTION of the DRAWINGS,

(See Plate XVI.)

Fig. 1 represents a circular lamp or lanthorn, made to fit into, and turn half round, in Figs. 2 and 3, and when VOL. II.-SECOND SERIES.

Fff

united

united or joined by solder or otherwise, forming a case, blind, or shade, for Fig. 1, for shading or darkening the light when required. A, is a small bolt or pin, made to pull up and push down, and to bolt into tube B, for the purpose of fastening door C when shut. D, is a ring, knob, &c. by which the lamp or lanthorn is turned when put or placed in the blind or shade Figs. 2 and 3, for the purpose of shading the light and preserving the glass. Fig. 1, when put or placed in Figs. 2 and 3, is united or made fast thereto by a hasp, or other proper fastening, fixed or attached in the usual way to the top of the case. E, is a small tube or hole to receive the catch or contrivance A in Fig. 4, for the purpose of fastening or uniting Fig. 1 to Fig. 2. In this case a common barrel is used therewith, for the convenience of turning the lamp or lanthorn round by the barrel in the case, shade, or blind.

Fig. 2, represents part of a case, shade, or blind, which may be either united to Fig. 3, or to a common barrel, as before described. Fig. 2 may also be made to turn round on the outside of the circular lamp or lanthorn if required; in that case the lamp or lanthorn must be attached or fixed to the carriage in the usual way, and an aperture or opening made in a case, blind, or shade, of sufficient length and width to admit the fastening of the lamp or lanthorn, so that the case may freely turn round backwards and forwards when the lamp or lanthorn is wanted to be darkened.

Fig. 4 represents the bottom of Fig. 2, with the addition of A, a catch or contrivance for uniting the same to Fig. 1, as before described.

Fig. 5 represents a square lamp, made nearly in the usual way; the door may be either made to open or shut as Fig. 1, or let down by a hinge placed or fixed at

the

the bottom thereof, and fastened at the top by a bolt or pin to a tube adjoining to the door.

Fig. 6 represents a square case, shade, or blind, made to receive Fig. 5. When Fig. 5, placed in Fig. 6, is wanted to be shaded or darkened, it must be taken out and reversed with the glass next the back part of the case, shade, or blind, and vice versa when light is again wanted.

Fig. 7 represents the rim or top of Fig. 6. A, A, are hasps, or other fastenings, for uniting or fastening the lamp or lanthorn to Fig. 6.

Thus have I given what I conceive to be a plain de scription of two of the most common-formed lamps or lanthorns in use, which will be sufficient for any workman of common abilities not only to make the same, but every other description of lamps or lanthorns to which the principle of my invention can be applied, such as ovals, oval circulars, octagons, sextagons, globular triangulers and Italian, (or round fronts and square sides,) which differ only from the above-described lamps or lanthorns in form or shape, the sole application of my principle therefore to which, as well as to all other lamps or lanthorns to which my invention can be applied, I claim as constituting my invention. The case is so constructed as to act as a shade or blind to circular, square, and other shaped carriage, or other lamps or lanthorns, for the purpose of shading or darkening the light when required, and preserving the glass from being broken; and if any accident should happen to the carriage, that the same may be taken out of their cases, &c. and used as hand lanthorns, and at pleasure replaced again.

In witness whereof, &c.

Specification of the Patent granted to WILLIAM DOBSON,

of the Strand, in the City of Westminster, Hardwareman; for certain Methods, by means of Machinery, never before applied for that Purpose, of chasing away Flies, and venomous Insects, calculated to promote the free Circulation of Air in Rooms, and to disperse the offensive Effluvia and Steam arising from Meat, Viands, &c.

Dated November 25, 1802. With a Plate.

To all to whom these presents shall come, &c. Now KNOW YE, that in compliance with the said proviso, I the said William Dobson do hereby describe and ascertain the nature of my said invention, (which I denominate the Zephyr,) as follows; that is to say: In describing the form of this machine, I shall endeavour to avoid, as much as possible, the introduction of technical terms, using only such as are most universally understood.

The zephyr consists of the following parts, viz. the pillar marked a a a, (Fig. 1, Plate XVI.) at the top of which is a globe, vase, urn, or flat circular box, marked b, for containing the movements, which are wound up by a key at the hole c, the arms on which the sails are drawn ddd, the whole of which is supported by a moveable pedestal e. The pillar consists of cylindrical tubes, of different diameters, the smallest of which is inserted, and slides into the larger, like those of a telescope, by which means the sails may be so altered as to act either above the heads or before the faces of the company, as may be most agreeable, so that the pillar is fixed or draws out, screws out or winds up, of one piece or many, plain or ornamented. The urn or box at the top of the pillar contains the power which gives motion to the machine; it consists of the strongest and simplest elock, jack, and watch work, that can be used. There

are
