54. For a Machine for Shelling Corn; Ira Smith, Downingtown, Chester county, Pennsylvania, February 13.

This machine does its work by means of a vertical revolving plate, constructed in the well known way of making such plates. The supposed novelty will appear from the claim, which is to "putting teeth or projections on both sides of the wheel, instead of on one side, as in the common method, thereby shelling twice as fast.” It so happens, however, that this contrivance is old, having been patented some years since, and subsequently re-invented more than once.

55. For a Machine for making Screws; William Keone, Monroe, Orange county, New York.

This machine is for cutting the threads upon wood screws; it is contrived with considerable ingenuity, and possesses much originality; it appears likely to operate well, and should it do so, and make screws with sufficient speed, it will be of great value; from want of the latter property, several such machines, in other respects very perfect, have been abandoned. The dies in this machine consist of two cast-steel wheels, about an inch and a half in diameter, fixed so as to revolve on axes, with their edges Dear. ly in contact; upon these edges the female screw is cut. They are so constructed as to be borne up towards each other, whilst the screw is being cut, and they, and the apparatus to which they are attached, are contained within a can, or vessel, filled with oil and water. A hollow vertical shaft passes through the bottom of the vessel, and through this shaft the requisite revolving motion is communicated. The contrivances to effect this, and the other requisite objects, are too complex for verbal description. The claim is to the combination and arrangement of the several parts of the machine for making screws, particularly the mode of giving the dies a simultaneous horizontal and vertical movement in oil and water, whilst cutting the screw." We do not think the former part of this claim sufficiently guarded, as the combination and arrangement may be much varied, whilst the result will be the same, and the means sabstantially similar.

56. For an improvement in the Wheat Fan; David Flanders and Calender Rathburn, Fort Covington, Franklin county, New York, February 13.

The general construction of this wheat fan is the same as those in common use, and although much pains have been taken to describe its individual parts, we are not told, and are unable to discover, in what its special utility and novelty consist.

57. For a Machine for Cutting Sausage Meat; Ambrose Henkel, Shenandoah county, Virginia, February 13.

The general construction of this machine may be inferred from the claim to "a cylinder with knives; secondly, their cutting between bars of any kind; and thirdly, the general construction of the machine." This claim is much too broad, the two first items in it not being sustained by their novelty, and not, therefore, sustaining the third.

58. For an improvement in Hydraulic Docks; Zebedee King, City of New York, February 13.

Those who are acquainted with the different plans which have been

devised for raising vessels out of the water for the purpose of repair, know that the principle of Bramah's press is applied to that purpose in the Hydraulic Dock, at New York, and probably elsewhere. The present patent is taken for improvements on the mode of constructing and using certain parts of that apparatus, which improvements are explained at large, and fully shown in the drawings, but cannot well be presented in a summary.

Specification of a patent for an improvement in the art of manufacturing

Rope or Cordage. Granted to WILLIAM FANNING, City of New York,
February 3rd, 1836.

To all to whom these presents shall come, be it known, that I, William Fanning, of the City of New York, in the county and State of New York, have invented a new and useful improvement on the art and manufacture of rope, or cordage, made from hemp, flax, cotton, manilla, cicol, or grass, and that the following is a full and exact description of the method of making the circumvolved rope.

What I claim as my own improvement, and not previously known, in the art and manufacture of rope, or cordage, is making the ready, or strand, of the rope, with as many true and separate spiral twists and turns, as there are circles of threads in the ready, or strand, when finished; which is done -by first taking as many threads as are necessary to form the inner, or centre, circle of the ready, or strand, placing them through as many holes made circular on a plate; they are then fastened to a machine sufficient to give sufficient turn, and drawn through a tube of proper size, giving to threads and centre circle of ready, or stand, a spiral form in exact proportion to its size. The first circle formed is then put through the centre hole of the plate, and as many threads rove through the holes of the plate in a circular manner, as are necessary to form the second circle; the threads and centre circle first formed, is then fastened to a second machine, standing a proper distance from the first named, and drawn together through a second tube of proper size, the circle of threads last rove completely circumvoling the centre of first circle formed, giving to yarns and second circle a spiral form in exact proportion to size of circle formed, and every succeeding circle is rove through the plate, tubed, twisted, and formed in the same manner as the above described second circle, giving to each circle a spiral form in exact proportion to its size, and every circle of threads rove separately through the holes of the plate tubed and formed, giving a true spiral form to each, will be completely circumvolved by the succeeding circle and rendered impervious to water: the threads are reeled separately on bobbins, and placed in a frame, as usual, in making other ropes. The machine used in making the circumvolved, together with the rope, or band, applied to the same, is such as has been in common use for many years, to which I have no claim of invention or improvement.


Specification of a patent for an improved machine for Cutting Straw.

Granted to Isaac S. WRIGHT, Elbridge, Onondaga county, New York,
February 3rd, 1836.
To all whom it may concern, be it known, that I, Isaac S. Wright, of

Elbridge, in the county of Onondaga, and the State of New York, have invented certain improvements in the construction of machines for cutting straw, and I do hereby declare that the following is a full and exact description thereof.

The straw to be cut is placed in a trough in the usual way, but the trough differs in form from those generally employed, being, most commonly, made out of two pieces of plank, joined together lengthwise, at right angles, or at any angle greater or less than a right angle, as may be preferred. This trough has a cutting koise at one end, which is fixed into a fraine sliding up and down in grooves, like a mill saw frame. This knife consists of two cutting parts, united together at the middle, so as to form a right angle, or any angle greater or less than a right angle, as may be preferred. The angle of the trough points downwards, and the angle of the knife upwards, the cutting edge being downwards. The gate, or frame, which carries the knife, may be moved up and down by means of a lever, a treadle, a crank, or in any of the known ways of producing such a motion. The fore edge of the trough is armed with iron and steel for the knife to cut against. Both the knife and the trough, may, instead of being in the angular shape described, be made curvilinear, in which case it will be best to make the curve a segment of a small circle in the middle, corresponding with the angular point above mentioned. The object in view will, in either case, be equally well attained; this object being so to form the knife and the trough, that as the former comes down upon the straw they shall concur in gathering and forcing it into a compact state. The same end may be partially attained by giving the described shape to the knife alone. I intend sometimes to surmount that part of the trough which is against the knife, by a short angular or curved piece in the same form with the trough inverted, for the purpose of keeping the upper portion of the straw more completely together whilst feeding. The feeding may be per. formed in any of the usual ways.

What I claim as my invention, and which I intend to secure by letters patent, is the angular, or curved, form of the knife above described, whether used with or without a trough, similarly formed for the purpose set forth, I do not claim the angular trough when used alone, the same having been previously employed, but without an angular or curved koife, such as is herein described.

Specification of a patent for a melhod of preventing ale, beer, and other mall

liquors from becoming acid in warm weather. Granted to Josiah Stow. ELL, Manchesler, Hillsborough county, New Hampshire, February 5th, 1836.

To all to whom these presents shall come, be it known, that I, Josiah Stowell, of Manchester, in the county of Hillsborough, and State of New Hampshire, have discovered and applied to use a new and useful method, or process, for preventing ale, beer, and other malt liquors, from becoming acid, or sour, in warm, or hot, weather, and from preventing the wash, or mash, of distillers, from becoming acid: and that the following is a full and exact description thereof.

To preserve malt liquor where the temperature of the weather is from seventy-four to ninety-four degrees, Fahrenheit's thermometer, for every

one hundred and seventy gallons of liquor apply one pound of raisins in the following manner: Put the raisins into a linen, or cotton, bag, and then put the bag containing the raisins in the liquor before fermentation. The liquor may then be let down at sixty-five, or as high as seventy degrees Fahrenheit's thermometer.

The bag containing the raisins must remain in the vat until the process of fermentation has so far advanced as to produce a white appearance, or scum, all over the surface of the liquor, which will probably take place in about twenty-four hours. The bag containing the raisins must then be taken out, and the liquor left until fermentation ceases. The degree of heat in the place where the working vat is situated, should not exceed sixty-six, nor be less than sixty degrees of Fahrenheit's thermometer.

To prevent distillers' wash, or mash, from becoming acid in hot weather, put about two pounds of raisios into one hundred and fifty gallons of the mash, the raisins to be chopped and put into the liquor without a bag, the wash may be let down into the working vat at seventy-five, on eighty degrees of Fahrenheit's thermometer, if the temperature of the place where the working vat may be, does not exceed seventy degrees. One pound of hops should be put into the wash, or mash, vat, for every eight bushels of malt, at the time of mashing, and three-fourths of a pound of hops for every bushel of inalt brewed, to be boiled in the liquor in the copper.


Specification of a patent for an apparatus for the drying of cotton and other

articles, and of protecting them from the effects of rain and storms. Granted to John PHILBRICK, Wilkinson county, Mississippi, February 12th, 1836.

To all whom it may concern, be it known, that I, John Philbrick of the county of Wilkinson, in the State of Mississippi, have invented an apparatus for the drying of cotton, after it has been picked from the plant, and of a great variety of vegetable and other substances, which require exposure to the sun and air; and by which apparatus they may be immediately protected from the effects of rain and storms; and I do hereby declare that the following is a full and exact description thereof, reference being had to the drawing which accompanies, and makes a part of, this specification.

I erect a staging, consisting of parallel rails, which are to support piatforms, troughs, or cars, upon which the cotton, or other articles, to be dried, are to be spread. These cars, or platforms, may be of any convenient dimensions, but for the sake of description, we will suppose them to be made five feet wide, and eight feet long, and the wheels, or rollers, upon which they run, to be six inches in height. In the accompanying drawing one of these rails is marked with the letter C, and rises six inches, or the height of the platform, above the rail upon which it reclines at its left end. P, B, K, L, are platforms, troughs, or cars, which rest and run upon the rails, having wheels, or rollers, upon their under sides for that purpose. The rails upon which the platforms rest, rise one above the other in the form of steps, as seen in the drawing; the platform marked K, is represented as having passed from the right hand rail on to the next platform, having been pushed forward by the man, H, and now stands upon the platform on the next rail, against which it catches, and both pass together under the shed in
