England, Sept. 17th, 1844, to run fourteen years from the 4th of May, 1843, the date of the English Patent.

The metal to be coated, after being cleaned in the usual manner, receives the first coating of tin by deposit from a solution of a salt of tin, the metal to be coated being immersed in a vat containing the solution, and put in contact, above and below, with pieces of zinc.This coating of tin is then covered with a second coating of zinc or other suitable metal, in the molten state. The machine for applying

, the second “consists of a pair of rollers, one above the other, together with what is called a back roller, which rollers are placed in a suitable frame, to sustain the gudgeons, or bearings. The back roller is used for the purpose of raising the sheets, or plates, out of the bath; but a bar of metal, or other device, may be made use of for this purpose. The pair of rollers are made to revolve in opposite directions, so that when a plate is introduced between the rollers it is carried forward by their revolution, and falling upon the back roller, which is placed above the level of the lower roller of the first named pair of rollers, and is situated as near as convenient to the pair of revolving rollers, is so far curved upwards that its end finds its way out at the surface of the molten metal,” which is contained in a bath, the rollers being in the molten metal.

Claim.-“I claim the coating of sheets, or plates, or pieces, of iron, or of copper, by the combination of the two operations above described, in the manner above set forth, or any other substantially the same, whereby the sheets, or plates, or pieces, of iron, or of copper, are first coated with tin by precipitation, and then passed through a bath of molten metal, as above described, in order to give the second coating. I further claim as my invention and improvement, the machine or apparatus, for coating plates, or sheets, or pieces, of iron, or of copper, said apparatus or machine being constructed and arranged in the manner described, or in any other manner which is substantially the same. But as the processes of coating first by precipitation, and secondly by means of a bath of molten metal, may be combined and consecutively used, without the aid of the machine herein described, and as I believe this combined process to be substantially new, I claim said combination whether the second process be performed by the aid of the machine or by that of dipping in the ordinary way.” 22. For improvements in the Permutation Lock; Robert Newell,

New York city, N. Y., September 17th.

The patentee says—“A main object of my improvements is to prevent the discovery of the position of the parts on which the security of the lock depends, either by the use of lights, or reflectors, introduce ed through the keyhole, or by an indication obtained by the lifting of the tumblers for the purpose of ascertaining the positions in which the followers and slides have been left by the operation of the key and bits at the time of the last locking. This I effect, in part, by the manner in which I have formed, arranged and combined a series of followers, slides, follower levers, and their appendages, and in part by the aid of what I have called guard plates, which form two distinct departments or separate chambers in the lock, thereby cutting off all visible communication with the said followers, slides, follower levers, and other parts.”

We are under the necessity of omitting the claim, as it refers to and wholly depends on the drawings.

23. For a machine for Cutting and Clearing Land of the kattoon

of' Sugar Cane; Norbert Lauve, Plaquemines, Louisiana, September 17.

The machine is made with two side pieces in the form of sleigh runners with handles like a cultivator at the back, and connected together, back and front, by two arch pieces; at the forward end there is a roller, and back of it two cutters, one following the other, with the cutting edges curved, and at the back there is a double edge cutter or cultivator, called in the claim a fluke, because of its resemblance it is presumed,) to the fluke of an anchor. In the claim the first cutter is designated by the letter F and the second by the letter G. These cutters run on the surface of the ground, or a little below it, and are made adjustable by screw bolts.

Claim.—“What I claim is the manner in which I construct my rattoon cutter and plant cane scraper as described, that is to say, I claim attaching to the bottom of the two sled runners the curved knives F and G in the inanner substantially as set forth; and in combination therewith I claim the fluke for clearing off the trash and dirt, constructed and arranged substantially as set forth. I also claim the combination of the roller with the above arrangement of knives, said roller being arranged in the manner and for the purpose set forth.”

24. For an improvement in Coffee Boilers ; Daniel Rowland, Wash

ington City, D. C., September 17.

This is for a mode of packing the joint formed by the union of a coffee pot and a condenser placed above, to condense the vapor rising from the coffee, and thus prevent its escape. The condenser is a cylindrical vessel containing water, and placed on the top of the coffee pot, by means of a flanch on the former, which slips over the latter. The lower edge of the flanch is turned in to hold a ring covered with cloth to form a packing.

Claim.-“What I claim is the mode herein set forth of securing the packing between the condenser and the coffee pot by means of the ring covered with cloth and the turned edge of the condenser by which it is fastened.”

25. For an improvement in Block Letters, Numeral Figures, Orna

mental Mouldings, fc.; Lewis Katen, New York city, N. Y., September 20.

This improvement consists in making block letters, or numeral figures, mouldings, cornices, or other ornamental parts of buildings in detached frames of metal, wood, or composition, and fitting stained glass into the frames, or inclosing gold or silver leaf, tin foil, or other

coloring matter behind glass, or other transparent substance, in the said frame with cement, so as to be impervious to air or moisture,

Claim.-“What I claim as my invention, is the introduction into block letters, numeral figures, ornamental mouldings, cornices, and ornamental parts of buildings, of a coloring matter behind a plate of glass or other transparent substance in a manner which shall render it permanent and not liable to be tarnished by exposure to the air and moisture, in the manner set forth."

26. For improvements in the machine for Sticking Pins; De Grasse

Fowler, North Bradford, New Haven county, Connecticut, September 20.

The pins are delivered from a hopper on to the conductor, whicla consists of two pieces of metal (placed at such distance apart as to receive freely the shanks of the pins and not the heads, which have an inclination in the direction of their length, and the delivery end is curved to deliver the pins horizontally into the grooved slide of the sticking machine. The upper edges of the two pieces are beveled for a small portion of their length, to form a gutter for the reception. of the pins, and at the termination of the gutter they are beveled in the reverse direction to discharge the surplus pins into a gutter on each side to carry them off. This operation is facilitated by an angular piece of metal (designated in the claim by the letter en placed on the top of the conductor, which directs the surplus pins into the gutters.

Claim.-"What I claim as my invention, is-First—the combination of a sliding bed in which the grooves are cut for the reception of pins, with the stationary curved conductor, combined and arranged substantially in the manner and for the purpose set forth. Secondly, I claim the stationary conductors having two inclined bars with a downward curvature at the ends, as described, and in combination there with the gutters on each side into which the surplus pins pass, and are carried off, the triangular piece e aiding in the operation.In the above claim I wish it to be understood that I do not claim the inclined conductors when made straight, but only with the curved terminations."

27. For improvements in Balances; James H. Ball and Richard H.

Ball, New York city, N.Y., September 20.

The following claim indicates the improvements so clearly as to render explanatory remarks useless :

Claim.—“What I claim is, the combining of a spring balance with the various kinds of lever balances to which it may be adapted, for the purpose of rendering the weighing of merchandize more easy, certain, and expeditious; and this we claim whether the spring balance be used with or without our improvements upon it herein described ; secondly, we claim in combination with the spring balance described the addition of a second hand. Thirdly-We claim the spring balance described, consisting of the modes of preventing the trembling motion of the hands, viz., the liquor cylinder and dasher."

28. For an improvement in Cooking Stoves; James Lewis, Amster

dam, Montgomery county, New York, September 20.

This improvement is for “forming a double flue around the oven, by which arrangement the heat is made to circulate twice around the oven instead of once, thereby causing the cooking operations of the oven to be performed with much less fuel than heretofore consumed, and more equally.” The oven is below the fire place, and the draught passes from the fire chamber down the outside flue, along the bottom under flue, back again under the oven, up the same side that it descended, but in the inner flue; then between the top of the oven and bottom of the fire place, down the inner side flue, and up the outside flue on the same side to the pipe. There are dampers to carry the draught directly out if it is not desired to heat the oven.

Claim.-“What I claim, is making the stove with an additional fluie around the oven in the manner and for the purpose set forth.”


29. For an improvement in Horse Hames ; Joseph K. Slater, and

Sylvester G. Pratt, Boston, Mass., September 20.

This is for an improvement on improved hames, patented by Nathan Post, on the 15th of June, 1844, and noticed in this volume, page 90, and to which the reader is referred. The improvement consists in extending each of the bearers or purchase bars, which spring from the middle of each hame downwards as far as the lower end of the hame, by an intervening connecting piece of metal; or instead of connecting them in such manner, the bearer may be made of sufficient length, and be bent at right angles, and fastened at its end to the end of the hame.

Claim.—“Having thus explained our improvement we shall claim the same, that is to say, connecting the lower ends of the hames and bearers substantially as set forth, and for the purposes set forth.”

30. For an improvement in Cut-Off Valves in Steam Engines ;

Barnabas H. Bartol, Cold Spring, Putnam county, New York, September 20.

The valves are those known as slide valves, the seat of the cut-off being above that of the steam valve, and the former is operated by an arm on the stem of the latter acting against stops on the stem of the cut-off valve, the stops being adjustable for the purpose of regulating the cut-off.

Claim.—“What I claim as constituting my invention, is the manner in which I have combined the action of the cut-off and steam valves, by means of the arm attached to the stem of the steam valve, and the movable or sliding cams or stops, made adjustable on the stem of the cut-off valve, for the purpose of regulating the cutting off of the steam, by the action of the respective parts as herein described and made known."

31. For an improvement in Ships' Sails ; Archibald Trail, Great

Britain, September 24th, 1844, to run 14 years from the 24th of February 1844, the date of the English patent.

Claim.-—“Having described the nature of my invention,” says the patentee, “I would have it understood that I do not confine myself to the precise details described, and it will be evident that the directions of the strengthening cords, bands, or lines may be varied so long as the peculiar character of my invention be retained. But what I claim is the mode of manufacturing sails by applying strengthening cords, bands, or lines, crossing each other on opposite sides of the sails in such a manner as to support the canvas at intervals as described, and thereby giving additional strength to sails for ships and vessels."

32. For an improvement in the machine for Excavating Dilches;

Edwin Owen, Laporte, Louisiana, September 24.

To the forward part of the machine there is a triangular cutter lying horizontally for the purpose of clearing and cutting away bogs, brush, &c., and back of this shield, boards inclining backwards on each side from the beam, to carry the cut bogs, and brush, &c. beyond the surface to be ditched; back of these there are inclined cutters to form the sides of the ditch, which are attached at botton to the cutter whiclı forms the bottom of the ditch, and then come the mould-boards in a wedge form, the angle forming a cutting edge inclining backwards from the beam to the cutter. The inould-boards carry up the earth beyond the sides of the ditch, by two curved conductors attached to beams placed above the mould-boards.

Claim.—“What I claim is, the combination of the triangular horizontal knise and shield in the manner and for the purpose set forth. Lastly, I claim the combination of the conductors with the mouldboards in the manner and for the purpose specified, said mould-board being made to slant under at its front edge to facilitate its clearing.”

33. For an apparatus for Preserving Fruits and Vegetables by

means of Ice; Peter Kephart, Uniontown., Carroll county, Maryland, September 24.

The preservation of fruit or vegetables is to be effected by placing them in a chamber surrounded by ice, or water nearly at the freezing point, the apparatus being so contrived as to admit of changing the ice or water. The whole design being predicated on the fact that vegetables and fruits can be preserved for a great length of time in a perfect state by keeping them at a temperature near the freezing point without freezing.

The ice is deposited on the top of the compartment for fruit, &c., and the water therefrom circulates around the sides and bottom. And there are also tubes surrounding this compartment through which water of a higher temperature can be passed to moderate the temperature should there be any danger of freezing.

Claim.-“What I claim is the so constructing of said apparatus, in the manner described, as that the substances contained in the preserv. ing compartment may be subjected to the influence of the ice deposited on the covering, in conjunction with that of ice cold water produced by its melting; or to the additional influence of a thin stratum of
