The arms of the flyer i, i, are continued downwards, and united to a boss k, at the bottom, seen best in the sectional figure. Upon this boss is fixed the pinion 7, and the flyer is supported at bottom by the perforated bracket m, which is affixed to a stationary horizontal rod n, and the flyer is kept perpendicular, and held at top by a similar perforated bracket o, affixed to a stationary horizontal rod p; the rods n, and p, being made fast to the frame work of the machine. The flyer is made to revolve by means of a wheel q, upon the horizontal rotatory shaft r, which wheel takes into the pinion 7, fixed as aforesaid upon the boss at bottom of the flyer.

It will now be seen that the spindle and flyer move independently of each other, and that if different speeds are given to the shafts f, and g, they will be made to revolve with dissimilar velocities, and hence that the rovings coming through the central tube at top and down, one of the arms of the flyer will be wound upon the bobbin uniformly as the copping rail moves the spindle up and down. Having described the nature of these improvements, and the manner in which the same are to be carried into effect, the Patentee states in conclusion, that he claims as his invention, the peculiar construction of the flyer for roving cotton, wool, and other fibrous materials in connection with the mode of adapting and actuating the same, as described above.—[Inrolled in the Rolls Chapel Office, March, 1833.]

Specification drawn by Messrs. Newton and Berry.

TO PIERRE NICOLAS HAINSSELIN, of Duke-street, St. James's, in the county of Middlesex, architect and engineer, for his invention of a machine or motive power for giving motion to machinery of different descriptions, to be called "Hainsselin's motive power." -[Sealed July 26, 1832.]

THE above invention is stated in the Specification to consist in a machine for producing motive power, the action of which depends on the descent of an endless series of reservoirs filled with water, which water is raised to a suitable elevation for the purpose, principally by the action of the machine itself, and is another scheme to obtain something like a perpetual motion, which may be added to the long list of futile projects which have gone before it. In Plate XI. fig. 3, is a front view of this apparatus or machine; fig. 4, is a vertical section taken crossways of the machine; A, is a large drum ; B, B, an endless chain carrying a series of reservoirs, or buckets, or each bucket may be fastened by a hinge joint to the other, so as to form an endless chain passing over the drum; c, is a cogged wheel, working into the pinion D; and E, is an eccentric, more particularly described hereafter. F, is a fly wheel; G, G, is a balance beam carrying a segment of a circle at each end; H, is what is called an escapement for a pendulum 1, leaving a weight 12, on its end; K, K, arẹ two pumps ; L, is the main cylinder of the machine; м, an air pump; N, a pipe through which the water which works the engine is raised; o, is a reservoir to receive the water from the descending buckets; and P, is a reservoir to receive the water from the pipe N. In making these machines the Patentee particularly recommends that the following details should be observed, when it is required

to make a machine on this plan equal in power to a steam engine, of which the expansive force is equal to a resistance of 1,000 lbs. in a second. It will be seen that air and water are the two principal agents in my machine. Water, it is known, weighs from 60 to 62 lbs. the cubic foot, and it requires 32 cubic feet of air to balance 1 cubic foot of water; and I have found by various experiments, that my machine employs about three-fourths of its power to produce its own action. From these premises it results, that in order to have a machine on my plan equal to 1,000 lbs. per second, there must be 4,000 lbs. of water in the descending buckets, and 200 cubic feet of air condensed in the cylinder L, by means of the air pump м, which is worked by hand by the lever handle a.

Fig. 3, represents 64 buckets fastened together by hinge joints, in such manner as to form an endless chain of buckets, their motion being so contrived that they descend full at one side of the drum, and rise empty at the other side,the drum being about 3 feet 6 inches in diameter-25 of these buckets can retain water at the same time, and in order that the united weights of their contents may be 4000 lbs. it is necessary that each of the 64 buckets shall be of a size (whatever be their form) conveniently to hold 160 lbs. of water.

In order to supply the 25 descending buckets with the required quantity of water, the 2 pumps к, к, are placed a little above the lower reservoir o; the rods of these pumps plumb with the extremities of the balance beam G, G, by which they are worked. The capacity of each of these pumps should be such that each stroke of the piston should raise a column of water to the upper reservoir P, sufficient for the supply of 1 bucket, that is to say, 160 lbs. These pumps, which may be called hydroneumatic, are nearly like ordinary lift pumps, the only difference being that the pump

chamber is divided into two parts by the division ƒ, the upper part being furnished with the pist on of a force pump; the same rod e, works both the piston d, of the upper part of the pump chamber c, and the valve f, of the lower part of the chamber g. The pump rods e, e, are fixed to a chain h, h, which is attached to the segments on the ends of the balance beam G, G, and thereby made to work the pump rods, while the balance weights i, i, below the extremities of these chains, keep them at a proper degree of tension, and retain the beam on a just balance. The strong cast iron cylinder L, must be capable of resisting the force of the condensed air which it is intended to contain, say at least 240 lbs. The interior of this cylinder is furnished with a division j, by which an upper and lower chamber is formed, marked k, and 7; the lower chamber k, is intended to receive the water which the pumps K, K, feed it with by means of the pipes m, m, at every stroke of their pistons ; and in this chamber the water frees itself from the air which may have been pumped in with it, and which is suf fered from time to time to escape at the cock n, when a quantity has collected sufficient in any way to retard the action of the machine. It is from this lower chamber that the water is supplied to the upper reservoir p.

The upper chamber l, of the cylinder L, is destined to receive the air which is to be forced into, and thus condensed in it, by means of the small air pump м. It will be seen that two small pipes o, o, communicate with the upper chamber l, of the cylinder L, and the upper chamber c, c, of the two pumps K, K: these pipes are to let in the condensed air upon the tops of the piston d, d, to cause the downward movement of their alternate action; 9, 9, are two valves, each furnished with a lever t, t, which levers are connected by a pointed cross bar s, as shown in plan view

in fig. 2. As the two arms or levers t, t, of this contrivance project beyond the vertical line of the pendulum 1, they are acted upon alternately by the vibration of the pendulum, thus alternately opening and shutting the valves q, 7. The lower reservoir o, may be of any convenient capacity, but the upper reservoir P, should at least be able to contain as much water as twenty-five of the buckets can hold, and the ascending pipe N, through which the water is raised from the lower chambers k, of the cylinder L, to the upper reservoir P, should be of such a diameter as to contain exactly the quantity of water required to fill three of the buckets in the space between the point u, (which should always be in a line with the divison j,) and the point v.

The cock x, is to regulate the descent of the water from the reservoir P, into the buckets, which should be just equal to what is pumped up by each pump at each stroke of the piston; y is an air cock, communicating with the upper chamber 1, of the cylinder L, and is to let a portion of the condensed air escape when its too great density causes the engine to work at too rapid a rate.

z, is a cock for emptying the lower chamber of the cylinder L, when necessary, for repairs or otherwise, and a similar cock or valve should be made to the lower reservoir o, in case, at any time, it should be required to empty it. As it is necessary that each bucket, as it empties itself, should be replaced by a full one, the pinion D, should be so regulated with reference to the toothed wheel c, (which is fixed on the same axis as the drum A,) that at every half revolution of the fly wheel F, (which gears in with the pinion D, and is on the same axis with the eccentric E,) one of the buckets shall present itself in turn under the cock x, to be filled.

The pendulum 1, is fixed on the same axis as the balance beam G, G, and the object of the eccentric fixed on the axis of the fly-wheel is, to act upon that part of the pendulum
