point v, and the upper end of the perpendicular p, as that a straight edge shall touch the face throughout the said range; the lines between the perpendicular, and the end of the board, being straight, and inclined over, as described, and the lines of the face of the mouldboard parallel to its base also being straight as set forth." 5. For an improvement in the apparatus for Distilling Grain; Benjamin Roop, Mount Pleasant, Westmoreland county, Pennsylvania, May 6. The mash tub is to be surrounded by a jacket at such distance from the bottom and sides as to leave a chamber into and through which steam, or water, is to be conducted for the purpose of heating, or cooling, the mash. Claim. "I do not claim the mode of heating and cooling by a steam, or water, jacket; but what I do claim, is said water, or steam, jacket, in combination with a mash tub and mash rake, for the purpose of heating and cooling the mash." 6. For an improvement in the mode of Setting Logs on Saw-Mill Carriages; Benjamin Webb, Warren, Herkimer county, New York, May 6. The slide of the tail block projects beyond the side of the carriage, and is there provided with a roller, which, as the carriage is run back, comes against an inclined guide, by which it is pushed with the log on it; and, for the purpose of keeping up this action, the inclined guide is attached to a slide which is, at each forward movement of the carriage, drawn towards the carriage a distance equal to the thickness of the plank to be sawed, and there held by a pall, on the slide catching in the teeth of a rack on the floor below the slide. The moving of the slide is effected by an arm that extends from and beyond the end of the tail block slide, provided with a latch, which, on the forward movement of the carriage, acts on the back face of a bevel attached to the plate of the inclined guide, and back of it; this bevel is made adjustable for the purpose of regulating the thickness of the log to be sawed, and the catch is jointed, so that, on the return of the carriage, it may pass over the bevel. Claim.-"What I claim as my invention, is setting the end of the log by causing the end of the slide upon which the log is dogged, as the carriage is gigged back, to come in contact with an inclined guide, which is again moved laterally towards the carriage the required distance for another and similar set, as the carriage advances towards the saw, by means of a latch, or other similar appendage, in contact with an inclined gauge, or adjustable bevel, attached to the slide carrying the aforesaid guide, in which position the said inclined guide and gauge are held by a pall attached to the said slide dropping into a rack fixed on the frame of the mill, or other suitable place, and this method of setting the log I claim, whether it be effected by the combination of parts above set forth, or any other, substantially the same for producing like results." 7. For an improvement in Wrought-Iron Wheels; James McCollum, Wilsonville, Shelby county, Alabama, May 6. Claim.-"What I claim as my invention, is the described mode of uniting the hub and the spokes, by making the latter embrace the former, instead of being inserted as heretofore done, by which arrangement the connexion between the hub and the rim of the wheel is stronger, and the hub is less liable to bend out of the central line." 8. For a mode of Catching Moles; Thomas Shailer, Haddam, Middlesex county, Connecticut, May 10. A number of pointed wires are attached to a sliding board, with their points downwards, and to the upper part of the slide there is attached a cord, which passes over a roller, to hold up the slide with its teeth, or wires, and having its other end provided with a fly lever, connected by means of a notch with one end of a trigger lever, the other end resting on the surface of the ground, so that the moving of the earth by the mole shall liberate the fly lever, and permit the slide with the pointed wires to fall on to the mole. Claim. "What I claim as my invention, is the manner in which I have combined the lever, one end of which is to rest on the ground, with the sliding board, and the pointed wires with each other, and with the other parts of the trap, so that the raising of the ground by the mole shall cause the wires to descend; the respective parts being arranged substantially as described." 9. For an improvement in the machine for Planting Rice and other Grain; Richard I. Gatling, Murfreesborough, Hartford county, North Carolina, May 10. In this machine there is a horizontal roller with channels, or grooves, in the direction of its circumference, and at distances apart equal to the space between the furrows; above this is placed a hopper, with a leather bottom, resting on the roller, and having a hole for each channel, through which the rice, or other grain, passes into the channels, by which they are carried down into inclined spouts, that discharge them in the furrows, prepared by teeth, forward of the inclined spouts. Claim. "What I claim as my invention, and desire to secure by letters patent, is the combination and arrangement of the perforated hopper, revolving channeled cylinder, and inclined conductors, as described." 10. For an improvement in the Double Plough; Aaron Smith, Bloomfield, Oakland county, Michigan, May 10. This is termed by the patentee, the "Double Sub-Soil Plough:""It has two mould-boards, and their proper appendages, placed one before the other on the same beam; the hind plough being so proportioned and arranged as to raise and lay its furrow slice on that of the forward one." The forward plough is smaller, and does not cut so deep as the hind one. Claim. "I do not, in this patent, make any claim to the manner in which I attach the land-side and mould-board to each other; nor do I herein make any claim to the particular manner in which I form the face of the mould-board; nor do I claim the placing of two mould-boards upon one beam; nor the causing of the rear plough to throw its furrow slice upon that of the fore plough, these having been effected by a plough for trenching; but having ascertained by varied experiments, that not only the special form of the outline of the two boards in their relationship to each other, as well as that of the turn of their surfaces, are points of great importance, I do claim the special form given to the two boards in their outlines, as designated by the numbers on the vertical and horizontal lines in figures 8 and 15, and on the lines showing the width in figures 7 and 14, (see accompanying diagrams;) these numbers, however, being taken as relative, as the size of the whole plough may be varied. It will be manifest, that in making this claim I cannot intend that these measurements should be taken with mathematical exactness, but that the outlines and proportions should be substantially the same with those set forth. I claim the particular form given to the heel of the hinder mouldVOL. IX, 3RD SERIES. No. 1, JANUARY, 1845. 5 board, as shown by the triangular space a', s, in fig. 8, and the hind view of this part in fig. 8, bis, by which form the slice deposited by the fore plough is left undisturbed, and that cut by the hind plough is raised preparatory to its being deposited upon it." 11. For an improvement in the Caps of Hand Lamps; Robert H. Eddy, Boston, Massachusetts, May 10. This is for an improvement on an oil feeder and lamp cap, patented by Joseph Benson, on the 28th of February, 1844, and noticed in this Journal at page 245, of volume viii, 3rd series, to which the reader is referred, to enable him fully to understand the improvement set forth in the following Claim. "I shall claim the combination of a cup, or receptacle, with the chamber, the object of the said cup being to catch any carbon which may drop from the inflammable portion of the wick; also the addition to, or combination with, the cap of the inclined lip surrounding the exterior edge of it, and extending from and above, the object of the said lip being to prevent any oil, or carbon, that may be in the cup, from running over and dropping on the outside of the lamp whenever the lamp is turned over into a horizontal, or inclined, position; also making the chamber entirely within the collar, or neck, in combination with a lip raised upon the upper edge of the collar; the object of such an arrangement being to arrest any oil which may escape through the screw of the lamp cap, or between that formed upon the exterior of the chamber, and the interior of the collar: the whole of the above being constructed and operating substantially as specified." 12. For an improvement in the method of applying Water, or Animal, Power as a motive force; John A. Wiszt, Philadelphia, Pennsylvania, May 10. The general principle of this device is well known, and has often, in by-gone years, been patented, and abandoned as often as essayed. It consists of an inclined wheel on a horizontal shaft, so connected with it, as to be capable not only of changing its inclination relatively to the shaft, hut of causing any part of its circumference to assume the lowest point of the inclination, whilst the shaft remains vertical, so that a weight, whether water, or animal, or any other ponderous body, traveling around on the wheel, will cause every portion of its circumference in succession to descend to the lowest point, without rotating the wheel, and thus causing the shaft, which passes through an enlarged and flat hole in a cylinder, that turns freely in the hollow hub of the wheel, to rotate. The claim is limited to the manner in which the connexion between the wheel and shaft is formed, and as it refers to, and is wholly dependent on, the drawings, we are under the necessity of omitting it. 13. For an improvement in Life Preservers; Callistus Augustus De Liancourt, Paris, France, assigned to Joseph Francis, of New York City, May 10. We deem the insertion of the claim sufficient to enable the reader fully to understand the character of this improvement. Claim. "What I claim as my invention, is the making of life preservers, buoys, rafts, and other articles for buoyant purposes, by distending the air bag with a helical spring, or with separate hoops, or rings, of iron, or other metal, whalebone, or any kind of wood, covered with any suitable, or proper flexible, material, and in combination with this the mode of making and attaching ends of any proper material, one of which is provided with a valve, by which arrange |
