scribed; the peculiar back and forth motions of the lateral distributors from end to end of the roller-which has never been so effected in any printing machine which has ever come to my knowledge."

Patent Re-issued in the month of September, 1844.

1. For an improvement in the mode of supplying Steam Boilers, and in the manner of operating the valves of Steam Engines; Henry R. Worthington, New York City, September 7.

This patent was originally granted on the 24th of July, 1844, and noticed in this journal, vol. ix, third series, page 178, to which the reader is referred for a description of the apparatus.

Claim."What I claim, is the employment of a spring in combination with the steam valve of an auxiliary engine, for supplying a boiler with water, so arranged, substantially as described, as to admit of its being properly armed or compressed by the action of the engine upon an intermediate piece, or lever, while the steam valve remains at rest, until, at the proper time, by the farther motion of the engine, the spring is released, and also to draw said valve independently of the momentum of the engine, in the manner and for the purpose above fully set forth."

24. For a machine for Cutting Crackers; William R. Nevins, New York city, New York, November 10.

The cutters are attached to the faces of a rotating polygon. The dough is rolled between two rollers and then passes between the lower of these two rollers and the cutters which form the crackers that are carried around and deposited on an endless belt, by means of a follower in each mould which forces the crackers out, this is effected by bolts to which the followers are attached, and which are surrounded by spiral and bow springs to keep the follower drawn in against the bottom of the mould until they come around to that part of the circuit at which the crackers are to be discharged, at which time the heads of the bolts are brought against springs projecting in manner similar to cams from a cylinder within the polygon of cutters.

Claim. "What I claim is,-First-the arrangement of the cutters on a polygonal drum; Second-the spiral springs in combination with the bolts, and the manner in which they are intercepted by the springs; the whole combined substantially as set forth."

25. For an improvement in the Pump; Joel Farnham, Stillwater, Saratoga county, New York, November 10.

Claim. "What I claim, is the before described construction of the

box bolted to the bottom of the cylinder, and side trunk and cap, for simplifying and reducing the expense of the pump and its liability to get out of order, as set forth-that is to say, making a single solid cast iron box, divided into three chambers by a transverse partition, forming a receiving chamber, and a longitudinal partition extending from said transverse partition to one end of the box forming the two discharging chambers having the top perforated with six apertures, two over the first mentioned chamber, and two over each of the other chambers, and having the bottom perforated with a single aperture leading to the receiving chamber for the admission of the water to the said chamber, doing away with the lower or under cups, and valve, plates and valves, and the necessary packing, and bolts for securing the same, in the manner and for the purpose set forth."

26. For an improvement in the machine for Cutting Shingles: Lloyd White, Jeffersonville, Clarke county, Indiana, November 10.

"I am aware," says the patentee, "that shingle machines have been made with two knives so arranged as to approach each other in shaving the shingle from the butt to the point, but in such cases the block moves up towards the knives, which have no other motion than towards each other while the taper is being formed, and therefore I do not wish to be understood as making claim to the employment of two knives that approach each other in cutting from the butt towards the point. But what I do claim as my invention and desire to secure by letters patent, is the combination of the two plates, or gates, with the knives attached to them and working in slides which approach each other towards the bottom, for the purpose and in the manner described."

27. For an improvement in the construction of Bridges; Josiah Rogers, New York city, New York, November 10.

Claim.—“What I claim, is the constructing of a cylindrical bridge, either of wood, or iron, by the combining together of circular ribs, string pieces, and diagonal braces, which braces consist of continuous strips of wood, or of iron, surrounding the ribs and string pieces, and passing spirally in reversed directions from end to end of the bridge, thus constituting a braced lattice work on the exterior of the cylinder. The whole being constructed, arranged, and combined substantially in the manner set forth.

"I also claim, in combination with such a cylinder bridge, the forming of a rectangular passage way, having its vertical sides, or a vertical partition, constructed, arranged, and combined substantially as made known."

28. For an improvement in the Tuyere for Blacksmiths' Forges; Joseph Lauback, Middletown, Dauphin county, Pennsylvania, November 10.

A vertical hollow cylinder with a basined rim at the top and a valve at the bottom, is let into the hearth, the basined part at top being

made to receive the coals, and the valve at the bottom for the discharge of the cinders which may fall through. Instead of a grate for the hearth, there is a triangular piece of cast iron on a shaft placed in the upper part of the cylinder, the shaft being provided with a crank handle for turning or vibrating it, and the edges notched for the passage of the blast from a bellows, the nozzle of which is introduced near the bottom of the cylinder.

Claim. "What I claim, is constructing the blacksmith's forge with a revolving or vibrating hearth in the manner and for the purpose set forth, and in combination there with the cylinder with the basined. rim forming part of the hearth and having a tube to receive the nozzle of the bellows, said cylinder receiving the blast from the bellows, and serving as a receiver for the small cinders, as described."

29. For an improvement in Water Backs for Forges; William McEwen, Norristown, Montgomery county, Pennsylvania, Novem

ber 10.

The improvement "consists in so constructing it that the cast iron box, or tank, which contains the water, and the fire end of which constitutes the forge back, shall project into the body of the forge to a distance beyond the wall, or stack, which constitutes the brick work, or masonry thereof, so that the blast shall issue from the nozzle, or tuyere, in advance of the ordinary forge back; by which improvement it is specially adapted to the heating of wide bars or other large masses of iron."

Claim. "What I claim, is the forming of the box, or tank, with a projection, or offset, so as to cause the blast from the bellows to escape from the nozzle, or tuyere, in advance of the line of the ordinary forge back, in the manner and for the purpose set forth."

30. For an improvement in Suction, Lifting, and Force Pumps; Chapman Warner, Lexington, Fayette county, Kentucky, Novem

ber 10.

This "consists in combining two vertical cylinders of unequal diameters, the smaller one arranged above the larger one, at a short distance therefrom, leaving their axes coincident with an air chamber of greater diameter than the lower cylinder, formed on the upper end of said lower cylinder and surrounding the upper cylinder, whose flanch forms the top thereof, covering the space between the outside small cylinder, and the inside of the air cylinder with a spout passing down through said flanch to near the bottom of the air chamber, having two pistons on a single piston rod, moved by a connecting rod and lever, one of which pistons is solid and moves in the upper, or small, cylinder, for forcing, and the other, which works in the lower, or large, cylinder, is perforated for the passage of the water through the same, is for lifting the water, and also for forming a vacuum_in the larger cylinder into which the water rises through a lower valve on the bottom of said large cylinder, and also at the top of the pipe leading to the well of water."

Claim. "What I claim, is the manner of combining the two cylinders of unequal size with an air chamber having a spout so as to produce, by means of two pistons, arranged as set forth, an equal discharge of water at the upward and downward stroke, or nearly so, substantially as described."

31. For a Pressure closing Stop Cock for Conduit Pipes; Horatio Allen, New York, November 12.

A chamber is formed in the pipe, "of dimensions proportionate to the area of passage which the cock is to provide; on the inner surface of this chamber is a projection, or shoulder, of a depth sufficient to afford an adequate lap and seat to the valve which is to close against it." The plate which is to close against it is jointed to an arm projecting from a shaft which passes to the outside of the pipe or chamber, and there provided with a hand lever for opening or closing the valve, and this lever is acted upon by a spring to assist in opening or closing the valve and retaining it in place. By this arrangement the valve is kept to its seat by the pressure of the water acting against it. Claim. "What I claim, is, first, the combination of a suitable seat, formed in the inside of a pipe or of a chamber to be placed in the line of the pipe, with a plate or valve closing with the pressure against said seat, the plate or valve being carried by an arm attached to a shaft which is worked by a handle outside the chamber; secondly, the combination of a spring with the handle outside the chamber, either acting with the pressure of the contained fluid to close the valve when the pressure is very light, or acting against the pressure if the contained fluid is very great."

32. For an improvement in Spectacles; Christopher H. Smith, Niagara Falls, Niagara county, N. Y., November 12.

The bows of these spectacles are without glasses, and to the main frame are attached, by swivel joints, two sets of different kinds of glasses; either or both of which can be brought to cover the open apertures or bows, and by means of the swivel joint, the glasses can be turned so as to have either set let into the bows, and the other at the sides or over them, and thus the colors or focal powers may be changed at pleasure.

Claim. "What I claim as my invention, is combining the glasses with each other and with the main frame, by means of the hinge and swivel joint arrangement described, which admits of the glasses being changed, and at the same time adapted to the vacant apertures, all as set forth."

33. For an improvement in the manner of arranging the screw, or spiral, propeller for Steam Ships or other vessels; Francis Pettit Smith, London, England, November 12, to run fourteen years from the 31st of May, 1836, the date of the English patent.

Claim. "What I claim as my invention, is the arranging, or placing, of a screw propeller in the dead wood, or dead rising, of a vessel, VOL. IX, 3RD SERIES-No. 5.-Max, 1845.

29

the thread of which screw shall make one entire revolution, or nearly so, upon its shaft, which thread may be in one continuous piece, or it may be divided into two parts, each making one half turn, or revolution, round the shaft, or be otherwise modified whilst it is made to operate in the dead wood substantially in the manner fully made known."

34. For improvements in the Cooking Range; Abiram Spaulding, New York City, November 12.

We are under the necessity of omitting the claim, as it refers throughout to, and is wholly dependent upon, the drawings, which are very numerous, and necessary to a clear exemplification of the improvements claimed.

35. For a combined Dumb and Parlor Stove; Alonzo L. Blanchard, Albany, N. Y., November 12.

The leading characteristic of this stove is fully expressed in the following

Claim. "What I claim, is the manner of combining with each other, a statue or other ornamental device, and a pedestal, divided into compartments, substantially in the manner set forth, so that they shall constitute a dumb stove, within which the heated air from a fire below shall circulate through the respective chambers, and through the body of the statue or other ornamental device placed upon the pedestal, as set forth. I claim, also, the combining with such a stove, a fire chamber, by means of which it may be converted into a parlor stove; said combination being formed by arranging the respective openings, chambers, and dampers, substantially in the manner made known. I claim, likewise, the particular manner of hanging the door of my parlor stove with concealed hinges, as described. And lastly, I claim the manner of supplying the draught to the fire chamber through a trunk, or hollow case, located and arranged as described."

36. For an improved apparatus for making Bedsteads; Thos. Cole, Greensburg, Decatur county, Ia., November 12.

This apparatus consists of a box, into which, the rails of bedsteads are secured and held by wedges and screws, and provided with guides for directing the saws in cutting the tenons, and the bits in boring the holes, without shifting the rails.

"What I claim is the particular manner of combining and arranging the respective parts of the box for receiving the rails, and for cutting the tenons thereon, and for boring the requisite holes therein, without shifting said rails during the operation; the whole being constructed. and operated substantially as set forth."

37. For an open Grate or Parlor Stove for Anthracite Coal; Otis Jenks, Albany, N. Y., November 16.

The claim in this patent refers throughout to the drawings, and without them, a clear notion of the structure and arrangement could not be given; and as, from their complexity, their insertion would
