These tongs are intended for grasping tightly pipes of different sizes ; and they maintain such good hold that the pipe can readily be turned or manipulated in any manner that may be desirable. The hooked jaw. A, and the short jaw, B, are constructed in the parts where the pipe is grasped, much after the usual and well-known manner; but the part of A through which the pivot, e, passes, is slotted and increased in size to compensate for the strength lost by the slot. The pivot, e, is secured in B, so that it can turn therein, or so that when e is prevented from turning, B can move about e as a center. There is a collar formed on e, and counter-sunk in B, which supports A, and is clamped between the collar and the washer, c, by the nut, d. e is flattened where it passes through the slot in A, for greater strength, and to prevent the pivot from turning therein. The inclined plane, E, forms part of A, or is fixed to it. The washer, c, is also an inclined plane, which is prevented from turning out of place by projections on the under side. It will be obvious from inspection of the engraving, that any strain which tends to separate the two parts of the tongs in the direction of their length, or to increase the distance between the surfaces of A and the tempered steel edge, of B, must cause the inclined plane of c to move up on the inclined plane, E, increasing the distance between the upper surface of the collar and the lower sur* face of the nut. This cannot be done without stretching or breaking the pivot by direct tensile strain. When much power is applied to the tongs, the nut, dj may become hard set. A light blow upon the end of handle, B, starts the pivot forward in the slot, and the tool is again ready for adjustment. Tongs made of steel, to work 5, f, |, and 1 inch pipe, weigh but four pounds ; and three sizes will take the place of the ten sizes now required, and perform better, at great saving of expense for repairs, than the single tongs now in use. The United States patent right (granted April 6, 1858,) is offered for sale by the inventor, who is in active trade, and has no time to devote to this business. A sample tongs may be seen, and particulars known on application to John Sawyer, No. 15 Gold street, this city, or at the office of the inventor, H. H. Gilmore, No. 1^9 Milk street, Boston, Mass. .

[A series of driving wheels are fitted on to an annular tread or way, and attached to radius axles connected at their inner ends, a wheel from which the power is taken being fitted on the driving wheels, the latter wheels rotating the former one with an increased speed due to their combined forward and rotating movements.] Mill-Stone Dress—Samson WolfiE, of Vicksburg, Miss.: I claim dressing mill-stones with elbow-shaped furrows, A and B, which are partly concave in their transverse section or curved as shown at a, and partly beveled in the same section as shown at b, and so con- structed that all the feather edges, c c, of the main furrows radiate from the center of the eye. B, of the stone, and that the elbows, d d, or commencement of the angles are at a point nearer the circumference than the eye of the stone, substantially as and for the purposes set forth. [By this method of giving the furrows a concave form in their transverse section from their commencement to their angle or elbow, they are made deeper and more roomy, and the grain is not liable to choke the action of the stonjs, and a rolling action is imparted to the flour, and the flour thus kept cool near the eye of the stones. And by giving the furrows a bevel form in their transverse section, from their elbow or angle to the circumference of the stones, they are made shallower between these points, and consequently the draft is not so great and the discharge of particles of grain with the flour does not occur. The accomplishment of these two objects in mill stones, as every practical miller is aware, has long been considered an important desideratum.] Construction oi^ Wooden Saddle Trees for Harness Saddles.—F. P. Ambler, Jr., of Trumbull, (assignor to F. P.
