which is thus raised. The bent lever, may, in some cases,
also conveniently serve to bring back the striker when
the breech-lever is raised. Also, according to this inven-
tion, in breech-loading firearms in which the breech is
opened and closed by a breech lever moving on a trans-
verse horizontal axis carrying the breech-block, he
arranges the lock within the breech-block, and he so con-
trives it that the opening of the breech puts the lock to
full cock. He prefers that the arrangement should be
such as is described in the specification of the patent
hereinbefore mentioned, where the lever is jointed in it-
self, and one part of it moving first in opening the breech
withdraws a wedge or filling-piece from behind the breech-
block. This part of the lever in so moving presses on the
tail of the tumbler, which is centred within the breech-
block, and has the striker jointed to it; the tumbler is
thus partly rotated against the resistance of the main
spring, and a sear catching into bents in the tumbler re-

carried by the block, but is so placed that, if pressed
back when the breech is closed, it comes against the tail
of the sear, and disengages it from the bent of the
tumbler, so as to let the striker fly forward and explode
the cartridge. In central-fire breech-loading cartridges,
as at present usually constructed, there is some liability to
miss fire in consequence of the anvil within the cap
becoming displaced. Now, to prevent this, the inventor
surrounds the anvil with a short piece of thin metal tube,
fitting it tightly, but entering freely into the interior of the
cap. In central-fire cartridges in which a flexible or paper
case is used, it is usual to enclose the flanges of the "hat-
cap "between two felt wads, which are sewn together,
and the wads so prepared are glued to the back of the
cartridge. In this case the percussion cap and anvil have
to be inserted afterwards, the glue having to be pricked
out of the vent in the hat-cap. The application in this
way of the percussion cap to the charged cartridge in-
volves some danger, to avoid which he forms an enlarge-
ment or thickening on the exterior of the hat-cap for a
distance along it equal to the thickness of the outer wad,
and he encloses a perforated metal disc fitting the outside
of the hat-cap between the wads. The wads are then
attached to the cartridge without the hat-cap, and the hat-
cap containing the percussion cap and anvil is afterwards
thrust into its place. He makes the hat-cap so that the
is able to move freely in it when it is thrust further in by

sharp blow on the fulminate, and ensures its explosion.-

3530 N. PAXMAN. Improvements in obtaining power in cylinders of steam engines. Dated December 12, 1867. This invention has for its object the more effectual application of steam to the cylinders and pistons of steam engines, whether horizontal or vertical, fixed or portable, marine or otherwise. The patentee places two pistons in the same cylinder, which pistons are driven by steam in opposite directions, the steam being caused to act upon the surface of each of the pistons instead of acting upon the cylinder covers, as heretofore, the result of which will be that the entire propelling force of the steam will be utilized and a considerable amount of power obtained. To the rod of the back piston he attaches a double, and to that of the front piston a single connecting rod, which are then fixed to and drive a crank shaft, giving motion to the other parts of the engine, the steam being admitted to the above that for, say, one-third of an inch, more or less, of a ing to this invention the patentee takes the warp so cylinder between the two pistons, and acting upon them simultaneously at each stroke when leaving the centre of the cylinder.-Patent completed.

This invention consists, first, in arranging the crank shaft of direct-acting pumping engines in such a manner that, when the engine is fixed horizontally, the contre of the crank shaft shall be above the centre line of pump piston, the crank shaft working in bearings fixed or cast upon the barrel of the pump. By these means the eccentric for working the slide valve of the steam cylinder can be placed in a direct line and level with the valve spindle or rod. The invention also consists in forming a boss or crosshead upon the plunger or centre of the piston rod, also above the longitudinal centre line, this boss forming a bearing for one end of the connecting rod or rods, the other end of the connecting rod working upon a crank pin inserted at a proper distance from the centre of the crank shaft to give the requisite stroke of piston and plunger. This crank pin is inserted into the boss of a small flywheel to form a crank when one connecting rod only is used; but, in some cases, two rods may be used, one on each side; then two flywheels may be used, or one flywheel and a crank on the opposite side. The invention also consists in forming a projecting shoe or slide on the opposite side to the crosshead boss on plunger or piston rod, this shoe or slide extending low enough to work upon a raised face or guide cast upon the bed plate which carries the cylinder and pump.-Patent abandoned. 3532 W.

thus or otherwise obtained are mixed with the proper
quantity of powder charcoal, and the mixture is treated

of the metallic particles. To prevent partial oxidation
the metalized ore must be cooled without access of air.
After mixing the ore thus metalized with the necessary

3547 W. M'ILWRAITH and J. BONNER. Improvements in apparatus to be applied to looms for wearing. ber 13, 1867.

This invention relates to an improved jacquard apparatus to be applied to power looms and hand looms for the purpose of working the heddles or healds, by the action of which the warp is shed for the passage of the shuttleboxes containing the weft, and by the crossing of which through the warp the cloth is produced. In the case of a hand loom, the treadles are connected by chains or cords to a pulley fixed on a shaft extending across the under part of the jacquard apparatus, so that as the treadles are alternately raised and lowered by the action of the weaver's feet, the shaft on which the pulley is fixed is alternately rotated through a circular segment in opposite directions. At each end, or other convenient part of the shaft, one or more discs having crank pins fitted into them (or, in place of discs, a pair of cranks or eccentrics may be used) is or are situated, the crank pins are coupled by connecting rods to the upper and under sliding box of the jacquard apparatus, so that, by the action of the revolving shaft, the sliding box containing the checks or horizontal needles are alternately thrown up and down in the frame, and the vertical needles or link rods lifted or allowed to

He forms the fireplace and grate at the front of and at a considerable depth below the oven, and fits the bottom with a sliding cast-iron water and ash retainer. The firebars he places above the ash pan, one above another, in a sloping direction, or inclining upwards and backwards from the bottom. Above the bars, and similarly inclined, he fits a stout metal plate with side flanges, so as to form (when placed against the brickwork or face of the superstructure of the oven) a feeding hopper or box for containing the coal, coke, or other furnace fuel. This feeding hopper or fuel container may and should extend from the top of the furnace bars to the level of the floor of the retort house, and be closed or fitted with a movable plate or cover. The mode of charging is as follows:-The covering plate last mentioned being removed, the feeding hopper is to be filled with fuel up to the level of the floor; the fire being then lighted, the furnace is then supplied with air through the horizontal spaces between the bars, inclined as before stated; the air thus passes entirely through the fuel, and causes a perfect combustion thereof, while the heat is conducted thence by surfaces of the retorts. flues to the oven above, where it is concentrated upon the As the fuel is consumed in or at the bottom of the furnace, the waste is supplied by the gradual descent of that in the hopper, and an uniform heat is thus maintained, while its intensity is increased by the more perfect combustion which results from the mode of admitting the air partly by the improved inclined grate, and partly by other ducts or flues.-Patent completed. 3555 F.

3573 W. HUSKISSON. Improvements in the manufacture of soda and other aerated waters, and in the manufacture of aerated bread. Dated December 16, 1867.

At the present time carbonic acid gas is produced in these manufactures from whiting and sulphuric acid, which leave an insoluble residue of gypsum, which is valueless and difficult to remove from the vessels. Now, according to this invention the inventor employs in the place of whiting dolomite or magnesite, consisting of carbonate of magnesia, as free as may be from carbonate or other salt of lime. A suitable material is found in the island of Eubea, in the Grecian Archipelago, and is imported into this country. He decomposes the dolomite or magnesite with sulphuric acid, and to assist the decomposition he heats the mixture. The gas which passes off he cools by passing it through a coiled pipe, having a stream of cold water passed in contact with it, and he then causes the gas to be absorbed under pressure in the The residue from the decomposition of the usual way. dolomite or magnesite is liquid, and is readily run out of the vessel; it is valuable for the manufacture of Epsom

moulding operations in the production of castings in iron,
brass, and other metals. The apparatus consists of an
inner frame or tube, which may be either rectangular,
circular, or of other shape or configuration, which frame
is hung loose and revolves upon a stationary shaft sup-
ported in suitable brackets, or in any other convenient
manner. Attached to the periphery or ends of this inner
frame are the moulds or patterns of the castings desired
to be produced, which may be one, two, or any convenient
number, according to their size.

On the same shaft on
forged, or otherwise fixed, and on these fixed eccentrics
another frame or tube is hung loose, and is capable of
revolving simultaneously with the inner tubes by means
of shafts or stays which pass through the frames; on these
shafts, or other convenient position, eccentrics are keyed,
and these eccentrics are, by preference, grooved to work
in bushes constructed to fit the grooves. The bushes have
clips attached to them, by which the moulding boxes for
containing the sand are held against the flauches of the
outer frame, and lowered by means of the eccentrics
worked by levers when it is necessary to remove the
boxes after the moulds have been formed. The bottoms
of these boxes are made to slide off when it is necessary
to fill them with sand. The motion of the inner frame or
tube to which the moulds or patterns are attached is circu-
lar, but the motion of the outer frame or tube is eccentric,
causing the moulding boxes to be pressed against the
patterns which are attached to the inner frame or tube, and
a duplicate of the patiern is produced ready to be run with
molten metal. The eccentric motion of the outer frame
or tube is such as to cause it to turn by its weight
