Specification of the Patent granted to CHARLES LUCAS BIRCH, of Great Queen-street, in the Parish of Saint Giles, in the County of Middlesex, Coach-maker; for an Improvement in the Construction of the Roofs and upper Quarters of Landaus, Landaulets, Barouche Landaus and Barouche Curricles, and other Carriages, the upper Parts of which are made to fall down.

Dated July 21, 1807.

To all to whom these presents shall come, &c.

NOW KNOW YE, that in compliance with the said proviso, I the said Charles Lucas Birch do hereby declare that my said invention is described in manner following; that is to say: Frame and fix in the top quarter rails to the tops of the standing pillars and slats, and fix the slats to the neck plates; rabbit the inner parts of the standing pillars, the top quarter rails and the slats, and board them with thin deals, or any other proper material. Let the crown-pieces or cornice rails be long enough to bevel or mitre into the corners of the top of the standing pillars; and let in the hinges and thimble catches on the top of the crown-pieces and top of the quarter rails. Fix on the hoop sticks and back and front rails, and board them all up except the two hoop-sticks which are nearest to the hinges, which may be placed as close as possible to admit of the head striking conveniently low. Conceal or let in one or more boxed locks to the centre hoop sticks, or at least the hoop-sticks which unite the thimble catches, and fix them so as that they may be opened by a key on the inside of the carriage. Stretch strong canvas, or other fit material, and nail it, or otherwise fasten it, both on the inside and the outside of the slats and elbows, and stuff it between with flocks or tow, or other fit material. Likewise stretch and nail on or fasten canvas, or any other VOL. XIII.-SECOND SERIES.

Y

proper

proper material, to the top hoop-sticks on the roof which are nearest the hinges before you put on the leather covering.

In witness whereof, &c.

OBSERVATIONS BY THE PATEntee.

In travelling, a carriage built upon this construction will carry one or more imperials on its roof without interfering with the regular process of opening it, and when in that situation will remain without doing the least injury to its upper parts.

The spring curtains to the landaus remain without being removed, whereas those on the old plan were obliged to be taken down, before there was a possibility of opening it.

Specification of the Patent granted to JOHN SHORTER MORRIS, of Pancras-place, in the County of Middlesex, Gentleman; for a Machine for Mangling.

Dated February 4, 1808.

With Engravings.

To all to whom these presents shall come, &c.

NOW KNOW YE, that I the said John Shorter Morris, in compliance with the said proviso, do hereby ascertain and describe the nature of my said invention, and declare that the figures and drawings annexed are explained in the manner following. The letters refer to the same figures in each drawing.

Figs. 1 and 2 (Plate VIII.) represent side views, and Fig. 3 a perspective view of the machine. aa, Fig. 3, a wood frame, put together with bed screws.

two horizontal, parallel, cylindrical rollers, whose axis bear on brass or iron let into the wood frame, one of which, b, is seen in Figs. 1 and 3. c, Figs. 1, 2, 3, moveable roller, round which the linen or cloth to be mangled is rolled, and placed on the two rollers bb. d a roller, the axis of which works in pieces of brass or iron e e, Figs. 1 and 2, which slides between two pieces of brass or iron let into the inner side of the wood frame. To the bottom of ee is fastened the long flat piece of iron ff, Figs. 1, 2, 3, with hooks at their lower extremity, to which is attached the chains ggg, which support the scale or platform h, on which iron weights, pig-iron, or any other heavy substance is placed. To the top of ee is fastened the engine-chains ii, which pass through an aperture at each end of the top of the wood frame, and is fastened on the pullies at each end of the shaft k with a screw. The ends of the shaft k work in cast-iron, screwed on the top of the wood frame Fig. 3. 7 a lever, which may be fixed to either ends of the shaft k. m, Figs. 1 and 3, a handle fixed to the axis of the top roller d.

To use the Machine press down the lever 1, Figs. 1, 2, 3, and fasten it with the hook n, Fig. 3, which raises the roller d, and the platform with weights on it. Then take out the roller c, and roll the linen and mangling cloth round it. Then place it on the rollers bb, unhook the lever, and the weights on the platform will press the roller d on the roller c, on which the linen is rolled. Put the top roller in motion by turning the handle m, and it will give motion to all the other rollers, and in a short time make the linen beautifully smooth; then press down the lever, fasten it with the hook, and take the -roller c out.

[blocks in formation]
[ocr errors]

The machine as above described will mangle almost all descriptions of linen; but if any large irregular lumps are formed by the linen rolled round the roller, I put a band round all the rollers: hence, when the top roller is put in motion, it will communicate motion to the two bottom rollers, and oblige the roller c to act with them; and shall sometimes fix a fly-wheel to the axis of the top roller, or fix a wheel with teeth on the axis of each of the bottom rollers, and one between them to connect them. Then the fly-wheel may be put on the axis of either of those wheels; the fly-wheel to be on the opposite side of the machine to the handle m. As a substitute for the platform and iron weights, a box may be suspended, in which stones, sand, gravel, or any substance may be placed to act as a weight.

The utility of this machine is not confined to mangling only, but may be used with success as a copperplate printing-press, a letter copying machine, or a cylindrical press, either as represented in Figs. 1, 2, 3. or with two rollers only; one with its axis bearing on brass or iron let into the wood frame, and the other as d pressing on it.

In witness whereof, &c.

OBSERVATIONS BY THE PATENTEE.

From experiments which have been tried with this machine, it appears to act best with a wheel on the axis of each of the bottom cylinders, and a pinion be tween them, with the fly-wheel on the pinion, and mo◄ tion given from the fly-wheel; thus it will pass over all inequalities with great ease. The top cylinders and weights rising and falling as they approach, from the

two

two bottom cylinders being put a little asunder, the one on which the linen is rolled acts as a wedge, greatly increasing the power of the weights, giving the linen three equal pressures. Upon the whole, this machine mangles with greater ease, performs its work better, and with more expedition than any before invented, and is very compact in its construction.

Harvest.

IN the beginning, middle, or end of August, accord

ing as the time of sowing has been earlier or later, and the season propitious, the seeds are ripe for gathering the poppy heads. Several methods have been recommended to harvest the crop. At first, the heads or balls were broken off from their stems, gathered together in large quantities, and deposited in a barn, or any other convenient.place, in large heaps, in order to dry them. This method was not only tedious but injurious; some of the balls becoming musty communicated a disagreeable taste to the seeds, and consequently to the oil, Mr. Poske, of Zell, in the electorate of Hanover, prefers the following method. He draws the entire plants out of the ground; binds a sufficient number of them at each extremity, and places them against each other in the manner of wheat-sheaves; and lets the whole remain in the field for eight or ten days, until they are perfectly dry. It was customary to cut open the capsulum with a knife: he prefers hacking it in two or three

places
