Improved Heliographic Instrument for Taking the Sun's Altitude—John Oakes, of New York City : I have stated that the main object of my invention is to find the altitude of the sun when the horizon is obscured ; but I by no means intend to confine its application to that condition, as it is obvious that it can be used as well when the horizon is visible; but it is under the former condition that it possesses an advantage over the quadrant and sextant. I do not confine myself to the use of any particular sensitive preparation for the concave surface of the hemisphere. But I claim the hollow hemisphere having its concave surface prepared with a sensitive coating, and having an orifice in the center of its equatorial plane, through which to admit the sun's rays, to act upon the said sensitive coating, substantially as and for the purpose set forth.

Automatic Grain-Weighing Machine — William and Thomas Schnebly, of Hackensack, N. J. : We do not claim to be the first inventors of weighing machines in which the weight of the grain was made to open and close valves for regulating the supply and discharge of the same, for many such machines have been made. Neither do we claim, broadly, in weighing machines, the operating of the parts which control the supply and discharge of the grain by means of the scale beam, or by means of parts connected with the scale beam; many other machines have been made in which this feature is seen—the patent of W. H. Bramble, April 8, 1856, is an example in point. In this device a connection is made for one of the purposes just mentioned, with the scale beam; our connection is behind, or in the rear of the fulcrum. It is a great and important point to have the scale beam elongated in front, or in advance of the fulcrum, and to operate the parts which control the supply of, and discharge of, the grain, by arms, MM", in front of the fulcrum. This arrangement permits the discharge valves, O O, to be kept open for the full exit of the grain until the opposite tub, I, has been filled. The valves could not thus be kept open if they were operated by means of the rear end of the scale beam. The use of the elongated arm in front of the fulcrum also permits a great simplification of the machine, and dispenses with the necessity of connecting rods and levers, lessens the number of points of friction, and promotes the probabilities of accuracy. We therefore claim the weighing of grain, &c., automatically, under a continuous flow or otherwise, without employing the gravity or weight of grain, being weighed for the purpose of checking or cutting off the supply of grain entering into the receptacles to be weighed, or for the purpose of discharging the grain from the receptacles in which it has been weighed, during the period ot the process of weighing, or when the quantity of grain is being determined or weighed, substantially in the manner as set forth. We claim providing the hopper with hinged valves, each having a lever with a weight on it, and attached thereto, when used in combination with projecting arms, which are made to operate the same, in the manner and for the purpose as set forth. We claim the balanced valve in its location below the hopper, and above the stationary chute or bridge, when used in combination with projecting arms^ cams, &c., and a pendulum with an adjustable weight, m the manner and for the purpose substantially as set forth. We claim the toggle joints in combination with vertical hinged valves, when operated on and for the purpose as substantially set forth. Steam Power Meter—George- Schuh, of Madison, Ind. : I claim the combination of the one independent piston, a, working in its cylinder. A, and actuated in opposite directions alternately by the steam from opposite ends of the engine cylinder, acting successively on its opposite sides or faces, carriage, B, pendulum, H, main spring, m, secondary spring, i, friction wheel or roller, c, and disk, E, arrrnged for operation together, in the manner and for the purposes set forth. Second, I also claim driving the disk, E, in both directions of its travel, by cords, T, operated by the engine, whereby a velocity corresponding to the velocity of the piston of the engine is at all times, and throughout both strokes, communicated in a positive and accurate manner to the friction wheel, c, for the purposes mentioned. Third, And I further claim providing the driving cords, T, with compensating springs, z, when said cords and springs are combined for action with the reciprocating disk, E, and reciprocating head-block, or its equivalent, of the engine piston rod, essentially as described, to prevent material pause of the disk at the end of each stroke, and irregularity in the action of the disk, bv the driving pull on either cord, alternately producing stretch and the relaxing of either cord, when not acting as a driver, for the purpose of securing accuracy in registering, as specified. Harvesting Machines—Wm. H. Seymour and Dayton S. Morgan, of Brockport, N. Y. : We are aware that various modes of changing the gear and the velocity of the cutter have been used in which the adjustments are arbitrarily made, but these require skill and care on the part of the persons employed. These we do not claim. But we claim, firat. The combination of the chang-able pinions and gear wheel actuating the cutters of reaping and mowing machines with their centers so situated relatively, that the changeable parts shall always exactly fit and gear when properly placed and not otherwise, the whole being arranged and operating substantially as set forth. Second, The combination of the replacable pinions with the series of holes for the axle of the driving wheel of reaping and mowing machines, so arranged with relation to each other that while the rate of motion of the cutter is changed, the hight of the cutter from the ground may be varied at the same time, the proper rate of motion for the different bights being always secured, and in such manner that the changable parts shall always fit and gear when properly placed and not otherwise. Punching Machines-D. S. Sherman, of Lowell, Mass. : I do not claim the device shown in the patent of R. H. Cole, dated June 3,1856. But I claim the manner of punching a nut, washer.or other article from plate or bars, by forcing it half way out (or more or leas) in one direction into a die, and then forcing it entirely out in the opposite direetion into another die. for the purpose of making the outside edges of the nut perfectly square and free from a sharp or burr edge, substantially as described.
