To JOSEPH GIBBS, of Kent Terrace, Kent Road, in the county of Surrey engineer; and Augustus Applegarth, of Crayford, in the county of Kent, calico printer, for certain improvements in steam carriages. -[Sealed 29th September, 1832.]

IN plate XIV.* fig. 1, is a side view of a steam carriage, constructed as described by the Patentees in the specification of the above Patent: fig. 2, is an end view of the same; a, a, is a wrought iron frame work or carriage supported by springs b, b, connected with axle c, of the driving wheels d, d, and steering wheel e.

The boiler or steam generator f, f, f, is firmly secured to the carriage a, and consists of three parts, the body of fire box f 1, made of strong plate iron, containing the water in a double casing surrounding the fire; ƒ 2, is a cylinder containing water, and filled with copper tubes about two inches in diameter, through which the fire and heated air pass from f 1, in a downward direction towards the chimney g. There is a connecting pipe h, to convey the water from ƒ 2, to f 1, as shown in the figure ; ƒ 3, is the steam chamber or separator, where the steam is separated and collected from the water; i, is a waste steam chamber upon the top of the separator, into which the waste steam is conducted by pipes in its passage from the cylinders to the chimney; the safety valve is placed in this chamber.

* Plate XIV. will accompany our next Number.

The construction of the various parts of this boiler will be better understood by reference to the sectional figs. 3, and 4, which will be described hereafter.

The cylinders of the engines k, k, are made in the usual manner, but move or vibrate in bearings 7, fixed or suspended from the frame a. The cylinders are supported by, and vibrate upon, the steam pipes m and n, which are cast with the cover of the cylinders, and are made hollow to admit the passage of the steam into and from the cylinders in the manner frequently used in vibrating engines; m, are the pipes which convey the steam from the separtor ƒ 3, into the cylinders; n, are the pipes which convey the waste steam from the cylinder to the chamber i; o, o, are the slide valves made in any of the usual constructions, and worked in the usual manner. The pistons of the cylinders are of the usual construction, and may be packed with metallic or other packing.

The ends of the piston rods carry friction rollers p, moving in the parellel guides q; the ends of the piston rods are connected with the arms or cranks r, firmly fixed upon the ends of the shaft s, turning in bearings suspended from the frame work. The crank arms r, are set at right angles to each other; and upon the shaft s, two toothed pinions t, t, are fixed; u, u, are two toothed wheels, which revolve freely around their axes upon the shaft or axle tree c, of the running wheels, and either of them can be occasionally connected with the shaft by means of clutches in the usual manner. The driving wheels d, d, are fixed upon the axle c, and the loose wheels u, u, are always in gear with the fixed pinions t, t; and as the wheels and pinions are made of different diameters, when either of them is connected with the axle tree c, a fast or slow motion will be communicated to the running wheels. The shafts, and the axle tree c, are securely connected together by strong links or couplers v, which keep the teeth of the

wheels u, and the pinions t, properly in gear. The springs b, b, are furnished with shackles at each end, in order that the action of the wheels and pinions may be influenced as little as possible by the motion of the spring. The shaft s, being connected with the frame work a, a, while the axle tree c, rises and falls with the springs, but in a curvilinear direction around the centre of the shaft s.

It should be observed that the shackles of the springs b, should be made of one piece of iron, and the pins should fit them and the springs exactly, to obviate side or swinging motion; and the teeth of the wheels u, and the pinions t, may be rounded at each end: the action of the machine will be evident by the figures. When steam is admitted into the cylinders, the pistons are alternately raised and depressed, which cause the crank arms 7, and the spindle s, with its pinions t, t, to revolve; and on its clutches being connected with one of the toothed wheels u, already in gear with its corresponding pinion t, it is made to revolve and carry the axle tree c, round, and consequently the running wheels d, with it, thus causing the whole machine to advance.

The guiding or steering motion is produced in the usual manner, viz:-the upright shaft or rod w, is moved by means of handles at its upper end. At the lower end is a toothed pinion, which works into a toothed segment x, fixed upon the divided or forked support y, connected with the steering wheel e, by means of two pairs of elliptical springs b. The support y, moves in bearing on the end of the frame work a, and has a pair of steady plates z, to keep it upright.

The

The seat of the conductor is over the water tank, the upper side of which serves as a floor for the stoker. boiler is supplied with water by a force pump, in the

usual manner; and the waste steam is conveyed from the chamber i, into the chimney by means of the bent pipe, which projects three or four inches into the waste chamber.

Fig. 3, is a horizontal section of the boiler, partly described under figs. 1 and 2. Fig. 4, is a vertical section of the boiter with all its parts; f1, is the body or fire box, which is surrounded by the double casings a, a, containing water; g, is the chimney; i, the chamber to receive the waste steam, as it blows off from the cylinders through the pipes n, n, described in figs. 1 and 2; b, is the safety valve, connected by a rod with the lever c, to which is attached the spring d, which may be regulated to the pressure required; m, is the pipe, which conveys the waste steam to the chimney; e, is the hopper, through which the fuel is supplied to the furnace; h, are the fire bars; ƒ 2, is the cylinder which contains the copper tubes j, j, and through which the fire and heated air pass in a downward direction from the fire box f 1, to the passage k, leading to the chimney g, in the direction shown by the arrows.

The cylinder ƒ 2, is made distinct from the fire box fl, and has its top and bottom ends made of strong plate iron, into which the copper tubes are inserted and firmly fixed. The water in the cylinder ƒ 2, communicates with the water in the double casings a, a, of f 1, through the pipe x, shown in fig. 1; o, is the feed pipe, which conveys the water from the force pump in the usual manner.

In ƒ 3, is fixed the apparatus for separating the steam from the water; p, p, is a circular plate of copper, which goes across the interior of the chamber ƒ 3, and is bent downwards in a conical form, as shown in the section; and as the steam rises from the surface, intermixed as it frequently is with boiling water, they pass together upwards in the direction of the arrows, and strike against the bot

tom of the circular plate p, p, which forces them back in a downward direction; the water, by its superior gravity, falls into the bottom funnel q, which returns it to the body of water; while the steam, being lighter, ascends between the circular plate p, and through the mouth of the top funnel r, into the upper part of the chamber ƒ 3, whence it goes into the cylinders through the steam pipe; if any water should have passed with the steam into the upper part of the chamber f 3, it will return down the funnel r, by its own gravity, as in the upper part of the chamber the steam and water are in a state of less disturbance.

The top funnel r, and the bottom funnel q, are supported from the circular plate p, by means of four rods.

When constructing a locomotive engine for propelling another vehicle for the conveyance of passengers, the Patentees propose that the steering wheel and the guiding apparatus should be removed from the locomotive engine carriage, and placed in front of that for carryng the passengers; and when the engine is used for drawing carriages containing goods, they are to be attached to the hind part in the usual manner.-Inrolled in the Inrolment Office, March, 1833.
