end jointed to a crank pin on the fly wheel, and the other to one end of a vibrating lever, by which a draw cut is given. At the junction of the knife and lever a connecting rod is jointed which extends down and is jointed to one end of a lever, turning on a fulcrum near the middle of its length, the other end being provided with a whetstone, which, as the knife descends, rises and rubs against the outer face of the knife, and sharpens it.
Claim. "Having thus fully described the nature of my invention, what I claim therein as new, and desire to secure by letters patent, is the adjustable whetstone so arranged and combined as that it shall meet in its ascending angular motion the edge of the knife in its descending angular motion, thereby setting the edge in towards the straw-rest, and giving the edge of the knife an appearance much like that of the sickle."
3. For an improvement in the Truss for the Treatment and cure of Hernia; Eliakim C. Darling, New Orleans, Louisiana, November 6.
Claim. "What I claim as my invention, and desire to secure by letters patent, is the use of a continuous metallic band entirely encircling the body and fastening in itself, and of such materials as not to stretch by use, but of such malleability as to allow any person to shape it to themselves at pleasure; thereby doing away with the use of leather or other straps of stretching material."
The pad and its appendages are connected with this metallic belt in the same manner as heretofore with the spring.
4. For a Balance Crane for Raising and Weighing Heavy Bodies; Louis Henry, Paris, France, assigned to Claudius Gignoux, New York city, New York, November 9.
"The nature of my invention," says the patentee, "consists in combining with a lifting crane, a weighing apparatus, so that the articles that are raised by the crane, can be at once weighed, thereby facilitating the double operation."
The mast of the crane instead of being supported at the top and bottom in permanent bearings, is connected with a standard, supported in the same manner as the mast of the ordinary crane, by means of links, and connected with a steelyard balance, so that the whole weight of the crane can be made to rest on the balance, and knife edges in links at the top of the mast.
Claim. "Having thus fully described my improvements, and the operation of the same, what I claim therein as new, and desire to secure by letters patent, is the combination of the balance or steelyard with the lifting crane, substantially in the manner and for the purpose herein set forth."
5. For an improvement in the Grain Cradle; Wm. A. Wood and John C. Loveland, Hoosick Falls, Renssellaer county, New York, November 9.
This is for making the teeth of metal tubes or partly of metal teeth and partly wood, instead of wood alone, and when made partly of wood and partly of metal, the hollow metallic part constitutes the extremity which is the most liable to bend.
Claim. "What we claim as our invention and improvement, and desire to secure by letters patent, is the use of said hollow metallic teeth and hollow metallic parts of teeth; the metal being less liable than wood to relax and straighten."
6. For improvements in the Cotton Press; Jedediah Prescott, Memphis, Shelly county, Tennessee, November 9.
The follower of this press is operated by means of two parallel levers jointed to the underside of it (one at each end) and to a carriage, that runs on truck rollers on the bed of the machine, and is worked by cords passing around pulleys and extending to a capstan. The ends of the box are let into grooves in the follower or platen of the press, and work up and down with it, and at the end of the operation they are lifted out of these grooves and liberated by two short levers that strike against projections on the frame-these levers are designated in the claim by the letter z. The lower edges of the sides of the box are jointed to the frame, and, when closed, are held in place by two bars, which are thrown up towards the end of the operation, by pins connected and moving with the platen.
Claim. "What I claim as my invention, and desire to secure by letters patent, is-1st. The combination of the inclined parallel levers with the horizontal carriage and rollers, arranged and operated in the manner and for the purpose set forth. 2d. The arrangement of the ends d of the box grooves in the platen, so as to rise and fall with the platen, and be liberated from it at the termination of the pressing.— 3d. The combination of the levers with the platen, arranged and operated in the manner and for the purpose above set forth. 4th. The manner of disengaging the bars from the box, by means of the pins upon the ascending ends of the box, in order to throw open the sides of the box, to tie and remove the bale."
7. For improvements in the Tide Mill; John Gerard Ross, New York city, New York, November 9.
The wheel is placed in a race, at one end of which there is a tide gate hinged to a wall beyond the end of the race and shutting against either side of the race; and at the other end of the race there are two current gates, one termed the "inner current gate," and the other the "outer current gate," these are hinged to the ends of the race way wall and shut against a pier placed beyond the end, and in a line with the middle of the width of the race way. The current in passing along opens the "current gate" and after acting on the wheel passes out through the "outer current gate," and on the return tide the pressure of water closes this "outer current gate," which causes the current to pass around to that side of the tide gate opposite to that at which it entered on the rise of the tide, throws it against the opposite VOL. X, 3RD SERIES-No. 1.-JULY, 1845.
side of the race-way, acts on the same side of the wheel as on the rise of the tide and passes out through the "inner current gate." The dam walls are formed with pits open at the sides for the free ingress and egress of the water to act on floating caissons which sustain the wheel and always keep it at the required elevation. The shaft of the wheel (or wheels) is connected with the frame work of the mill by bars radiating from the axis of a cog wheel, into which mash the cogs of the master wheel.
Claim. "First. I claim as new, and of my invention, and desire to secure by letters patent, the mode described of fitting the tide-gate I, at one end of a race-way, formed by an inner and outer dam-wall, in combination with an outer current-gate K, and an inner current-gate L, at the opposite end of the race-way; the whole constructed and operating substantially as herein described.
Second. I claim the mode of forming the dam-walls with pits, open at the bottom, to receive and float the caissons that carry the waterwheel; and the combination there with of the described means for regulating, adjusting, and directing the ascent and descent of the wheel or wheels, substantially as the same are described and shown herein. Third. I claim the combination of the described mode of fitting the gates and wheel, and making them act together in the manner described herein."
8. For an improvement in the Smut Machine for Cleaning Grain; Jacob Groat, Troy, Rensellaer county, New York, November 9. This is for the addition of a reservoir or spout to the case, or concave, which surrounds the beater and rubber, into which the grain is thrown, and the discharge therefrom is regulated by a gate, so that the grain may be kept in the machine as long as may be necessary to clean it thoroughly.
Claim. "Having thus fully described my improvement, what I claim therein as my invention, is, first, the regulating reservoir or spout, constructed as above described, in combination with the cylinder and concave, as herein specified."
9. For an improvement in the Means of Removing Mud, Sand Bars, &c., from the Beds of Rivers, &c.; Dennis Vermillion, Washington, D. C., November 9.
A mass of logs are put together in the form of a boat, to be moved down by the current, tide, or otherwise, and which from its great weight and strength will acquire great momentum. Iron breakers, sharpened at the lower end, pass obliquely through apertures in this mass, and extend down to the depth required to act on the obstruction to be removed. At the stern there is suspended a drag rake, connected with the boat by means of two arms that slide freely in apertures in the ends of a cylinder which is hung on appropriate journals; and for the purpose of raising this rake, cords extend from it to a windlass on the boat. The operation of the apparatus is this-The boat being put in motion by the current, or otherwise, is directed towards
the sand bank, or other obstruction, and the breakers and rake having been set to the required depth, the breakers cut up and loosen the sand, mud, &c., which is then raked into deeper water.
Claim. "What I claim as my invention, and desire to secure by letters patent, is the combination of a bulk of square logs, resembling the hull of a vessel, the adjustable breakers and the rake with its oscillating cylinder and windlass; the whole forming an apparatus for removing sand or mud bars or shoals, or other similar obstructions to navigation, from the beds of rivers and other waters; said apparatus being (substantially) constructed, and operated, as herein above described."
10. For an improvement in the Cultivator Tooth; James Birdsell, Hamilton, Chester county, Pennsylvania, November 9.
The nature of this invention consists in attaching a separate cutter to the tooth of a common cultivator constructed in the ordinary way; the said cutter being so formed as to be turned to make the heel become the point, and vice versa. It is convex on the upper, and concave on the under side, and the latter rests on the ground, so that being reversible it will keep sharp until worn out.
Claim. Having thus fully described my improvement, I wish it to be understood that I do not claim a self-sharpening cultivator tooth, as that is known; but what I do claim as my invention, and desire to secure by letters patent, is the self-sharpening convex cutter constructed substantially as herein set forth, in combination with the cultivator tooth, in the manner and for the purpose described."
11. For an instrument for Measuring Coats, Vests, &c, and for Drafting the same for Cutting; John P. Combs, Trenton, Mercer county, New Jersey, November 9.
Two scales are jointed together and provided with a protractor, and to each of these scales there is a measuring tape attached by eyelet holes and buttons at given distances apart on the face of the scales and corresponding with the marked divisions thereon.
Claim. "What I claim as my invention, and desire to secure by letters patent, are the jointed protractor, and the straps or measures, and attached with the screw and eyelet holes, as before described; by means of which all the angles necessary to be had, in order to insure a perfect fit, are easily and accurately obtained."
12. For an improvement in the mode of Constructing Fire Places and Flues; Daniel Hemingway, Leesburg, Harrison county, Kentucky, November 13.
The back of the fire place is vertical to a certain height, it then falls back about one foot inclining upwards to the height of the arch, and from this line it widens out on each side in a circular form, and contracts in the same manner to form the flue.
Claim. "I do not claim expanding the flue above the throat; but what I do claim as my invention, and which I desire to secure by letters patent, is dropping the back of the fire place below the arch,
in the manner described, in combination with the expanding flue, substantially in the manner set forth."
13. For an improvement in the Horizontal Wind Mill; Daniel Dennett, Centreville, St. Mary's Parish, Louisiana, November 13.
The wings or vanes of this mill are jointed to radial arms, and are suspended by cords to vibrating levers that pass through, and are jointed to, the shaft above the arms to which the wings or vanes are jointed, so that by this arrangement the moment one vane begins to make "back wind," (as it is termed,) it is blown down, and by its connection with the one on the opposite side of the shaft draws it up to catch the wind.
Claim. "Having thus fully described the nature of my improvements in the horizontal wind-wheel, what I claim therein as new, and desire to secure by letters patent, is the manner herein set forth, of combining the motion of the two opposite vanes by means of cords, chains, or rods, by which they are connected to the end of a vibrating beam, substantially in the manner and for the purpose herein made known.".
14. For a machine for making Tuscan or Leghorn Braid; Elisha Fitzgerald, New York city, New York, November 13.
It is to be regretted that, from the necessary complexity of the mechanical arrangements, a description without drawings could not be made sufficiently clear. After the pieces of straw have been deposited in a box, the whole operation of taking each separate piece, introducing, bending it over, trimming off the surplus, and transferring and retransferring the pincers or nippers by which the pieces are held, and the completed braid delivered, is carried on, with the most beautiful regularity, without the hand of an attendant.
As the claim refers to, and is wholly dependent on the drawings, we are under the necessity of omitting it.
15. For an improvement in the manufacture of Lamp Black; Gilbert Mini, Philadelphia, Pennsylvania, November 13.
The rosin or other material to be burned is put into a furnace which opens into a large room, without chimney or any other opening than the one communicating with the furnace.
Claim. "What I claim as my invention and improvement, and desire to secure by letters patent, is the mode herein described of burning lampblack-that is to say, burning it in a confined building or room without a chimney or draught, substantially in the manner set forth in the above specification."
16. For an improvement in the Point for Manifold Writers; Jesse K. Park, New York city, New York, November 13.
The "nature of this improvement consists in making a spiral flexible point, of either steel, platinum, gold or silver wire, or any other metal suitable for the purpose. Said spiral to form a cone and so
