2. For an improvement in the Scrubbing Brush; George Carver, Chambersburg, Franklin county, Pennsylvania, August 1.

The handle of the brush is connected with the block by means of a pin joint to secure an equal bearing of the brush on the floor, and insure its wearing equally, instead of at the edges, as when the handle is fixed.

Claim. "What I claim is the application of the joint and hinge to the scrubbing brush and block, whether in, on, or at the side, so as to operate in the manner and for the purpose described and set forth."

3. For improvements in machinery for making Wrought-Iron Butt Hinges; Cyrus Kenney, Troy, Rensselaer county, New York, August 7.

In the making of butt hinges of wrought-iron, the two halves are cut from sheet-iron plates, by machinery for that purpose, with projecting pieces from which the knuckles are to be formed; these projecting pieces are first partly bent by one operation, and then completed by a machine, patented some years ago by a Mr. Rouse. The first of these bending operations is effected under this patent by an arrangement consisting of a rest-die attached to the bed of the machine, and two dies and a gauge attached to one end of a working lever. The face of the gauge is at a distance from the inner edge of the rest equal to the space between the end of the tongue on the hinge plate, and that part where the bending is to be commenced, and the two dies are attached to the lever, forward of the gauge, one of them to strike the metal between the gauge and rest, and the other immediately over the rest. The knuckles after being completely bent, which operation elongates them, have to be trimined off, or up-set, and the second improvement under this patent, is to effect the latter object, which is done by means of two dies, one permanent and the other sliding, the space between the two, when nearest to each other, being equal to the required length of the knuckles. These dies are grooved and mortised to receive the flaps of the hinges, and thus bring the knuckle to be upset between the faces of the dies; there are also mortises in the dies to receive the knuckles that are not being upset.

Claim. "What I claim is the method of bending the ends of the projecting pieces which are to form the knuckles, by combining the rest, dies, and gauge, under an arrangement substantially as set forth, and so as to adapt them to the partial formation of the knuckles of the butt hinges. I also claim the method, herein described, of upsetting the knuckles of the butt hinges, by providing the pressing dies with grooves and mortises, or openings, to hold the flap and receive the knuckles, for the purpose and in the manner described."

4. For a Corselet for Curved Spines; Alanson Abbé, Roxbury, Norfolk county, Massachusetts, August 7.

This corselet is made of iron and other appropriate material in two parts, one adapted to the shoulders, the other to the hips, the two VOL. IX, 3RD SERIES. No. 4.-APRIL, 1845.


being connected together by an elastic strap along the middle of the back, or spine, so that the position of the two can be changed at pleasure.

Claim. "What I claim consists in the described mode of making the back of a corselet, viz., in constructing the same of two parts, and jointing them together, and otherwise arranging them with respect to each other, as set forth, and connecting them by an elastic strap, or straps, or other proper elastic materials, which have, or have not, means of increasing their elastic force, the whole being substantially as specified."

5. For an improvement in Lamps for Light-Houses; Winslow Lewis, Sr., and Benjamin Hemmenway, Roxbury, Norfolk county, Massachusetts, August 7.

These improvements are adapted to the kind of argand lamps employed in the light-houses of the United States; and the first consists in making the inner tube of the burner in two parts, the upper part being a ferule slipped on to the main body of the tube, so that when injured by the action of the flame it can be removed, and another substituted; and the second improvement is for an arrangement to support the chimney by means of brackets attached to the outer tube of the burner at sufficient distance apart to admit of turning the wick by a milled rim attached to the ferule which carries the wick tube.

Claim. "What I claim is as follows, viz., a movable cap, or ferule, applied to, or slipped upon, the inner air tube of the burner for the flame to act upon, instead of the top of the inner tube, as heretofore arranged; also the above described mode of sustaining and arranging the supports of the glass chimney, with respect to the tube, and milled. rim thereof, by which, in connexion with the other mechanism, the wick is elevated and depressed; the ordinary kind of glass holder being thereby dispensed with, and the wick raised and lowered without turning the chimney, or lamp glass; thus preventing the chimney from being smoked on one side, or its interior surface, as often takes place in lamps where it is supported upon a glass holder as ordinarily constructed; the whole of the above being substantially as explained."

6. For a machine for Rolling Irregular Figures to a Pattern; William Field, Pawtucket, Providence county, Rhode Island, August 7.

This is for a modification of the rolling mill, and consists of three rollers arranged one above the other; the bearings of the bottom one being permanent, the upper one movable, and provided with set screws for adjustinent, and the third, or middle, one movable up and down between the other two, the upper and the lower one being geared together to insure their moving with equal velocities. A pattern of a wedge-like, or other desirable form, is placed between the middle and upper roller, and the piece of metal to be rolled between the middle and lower roller, from which arrangement it will be evident that the pattern in passing through will, by its irregu

larities, cause the space between the middle and lower rollers to increase and decrease, and thus give the desired form to the article to be manufactured, provided the passage of the metal to be rolled be carried through with the same velocity as the pattern.

Claim. "What I claim is the employment of the rollers combined and arranged in the manner and for the purpose set forth, in combination with the pattern, for the purpose described."

7. For improvements in the method of making Vessels of soft metal, such as are used for containing pigments for artists, &c.; John Rand, a citizen of the United States, now residing in England, August 7.

The patentee says, "My invention relates, first, to a mode of forming thin metal vessels of metal tin, and other metals sufficiently malleable to be operated on by the process of pressing the same into the depth of vessel desired; and secondly, my invention relates to a mode of making a screw on the neck, or nozzle, of metallic vessels, and also the mode of making screw caps."

Claim. "I would have it understood that I do not confine myself to the precise details shown, provided the peculiar character of my invention be retained: but what I claim is, first, the mode described of making soft metal vessels by causing a thick piece of metal to be pressed in the required form, by pressure of dies as is described; secondly, I claim the making a screw by pressure in dies on the necks of metal vessels; and thirdly, I claim the making of metal screw caps by pressure, as described."

The method covered by the first section of the claim, is to place a piece of soft metal in a matrix, of the form of the intended vessel, but of less length, and to make pressure on it by means of a metallic follower of the form of the inside of the intended vessel, which will force the metal out of the matrix, cause it to form around the follower, and to assume externally the cylindrical form of the matrix. The method of making screws on the necks of soft metal vessels, is to place the end of the soft metal vessel within a die having the form of the intended screw, and then forcing a conical die within the neck which forces the soft metal into the threads of the matrix; and the method of making screw caps, covered by the third section of the claim, is the reverse of the preceding method.

8. For a machine for Turning Scythe Snaths, or Handles, and other similar articles; James Ombree, Marshalton, Chester county, Pennsylvania, August 7.

The timber is first prepared and reduced to an approximate form by a saw-mill with a double carriage-the lower one in the usual manner of saw-mill carriages, and the second, or upper, one resting on the first and moving longitudinally with it, there being a roller at each end of the second carriage bearing against transverse ribs projecting upwards from the first, or lower, carriage, to prevent the upper

one from moving lengthwise, but to admit of lateral play. The upper carriage is provided with clips near each end which embrace a guide of appropriate form, so that the saw, which is operated in the usual manner, shall cut the timber of the form required.

The piece of timber thus prepared is presented to the turning instrument by means of two parallel feed rollers, and two guides parallel with each other, and at right angles with the axis of the feed rollers; the two rollers are kept in their parallel relative position by means of links, in the manner of parallel rulers, and the two guides in the same manner, and these two sets are so arranged and connected with levers, that by means of weights attached thereto they always gripe the piece of timber.

The cutting instrument is attached to a hollow chuck, through which the piece of timber to be turned passes, the cutter projecting inwards, and as scythe snaths, and the other articles intended to be turned, are of a regular taper, it is necessary that the cutter should have a regular movement towards, or from, the centre of the wheel from the commencement to the end of the operation, which is effected by having the chuck which holds the cutter made in two parts, one turning on the other, the cutter sliding in the inner part, and being connected with an eccentric groove in the outer one, which moves the cutter in or out, as the two parts turn on each other, and to effect this the two parts are connected together by gearing in such manner that, as the whole chuck rotates with great rapidity the two move on each other with a very slow motion, the difference between the two giving the necessary motion to the cutter. There are three guides, or rests, which correspond with and move in like manner as the cutter. Claim. "What I claim is, first, the manner in which I have arranged and combined the apparatus for sawing the stuff to the proper curvature, said combination consisting of the first carriage, the second carriage with its friction wheels, the curved guide strips, and the clips with thin cylindrical stems received within holes in the ends of the second carriage, substantially as set forth. I also claim the manner of arranging and combining the two parallelograms in which the vertical guide pieces, and the toothed feeding rollers, are made to embrace, conduct, and direct the handle to be turned through the opening in the wheel, or chuck; the feeding rollers being made to revolve, and the other parts of the parallelograms being acted upon and governed as described. I claim the combination and arrangement of the parts employed in causing the cutter and guides to approach and recede from the centre of the wheel (chuck) during its rotation, as described."

9. For an improvement in the machine for Winnowing Grain; Thomas Cole and John Littlefield, Allensville, Switzerland county, Indiana, August 7.

In this winnowing machine the fan is made with inclined vanes to throw the current of air in the direction of the shaft;-it is directed towards the middle of the screens by means of two vertical and oblique


wings attached to the frame between the fan and the screens. grain passes from the hopper through two shaking horizontal screens, one above the other, and from the latter of these on to another which is inclined and permanent, the lower end of which discharges the grain into the upper end of a fourth and last that is inclined and rotating.

Claim. "What I claim is, first, the arrangement of the wings in the manner and for the purpose set forth; second, the combination of the permanent inclined rectangular screen with the revolving cylinder screen as set forth."

10. For an improvement in the Truck Frames of Railroad Cars; Charles Davenport, Cambridgeport, Middlesex county, Massachusetts, August 10.

The connexions between the pedestals of this truck frame instead of being made by means of solid pieces of timber extending from one pedestal to another on each side, are, by means of two tie plates of iron bolted together through the pedestals, one being above, and the other below; above the upper tie plate, and extending from one pedestal to the other, there is an arch plate connected with the pedestals by the same bolts that secure the tie plates. The two truss frames are connected together by means of diagonal iron plates bolted to the pedestals, and so twisted and connected in the middle as to form the opening for the king-bolt that secures the truck and car together.

Clain. "I do not claim making the truck frame of a railroad carriage with side truss frames united with diagonal braces, as this has been known before, nor do I claim making these frames of iron, or other metal; but what I do claim as my invention, is making the trusses of the truck frame that are united and braced together by means of twisted diagonal plates, of arch plates, and tie bars, so arranged and bolted together as to embrace and secure the pedestals as described, by which arrangement I obtain the necessary strength with greatly reduced weight, and employ the pedestals for the double purpose of holding the boxes of the wheel axles, and connecting the tie bars of the trusses."

11. For improvements in the process of manufacturing Iron, Steel, Copper, and other metals; Arthur Wall, Poplar, Blackwall, Great Britain, August 10, to run fourteen years from the 18th of November, 1843, the date of the English patent.

The first part of this invention consists in adding to the iron, while in a state of fusion in the smelting, puddling, balling, or reheating furnaces, certain compound masses, which the patentee has designated, for more clearly explaining his process, A and B.

The composition A, is a mixture of steel, or wrought-iron, in a comminuted state, such as filings, or fine cuttings, with melted rosin, in the proportion of two pounds of filings to five pounds of rosin; it is made into balls of five pounds each, and thrown upon the melted
