91. lappuse - Be it known that I, John Fitch, of Philadelphia, in the county of Philadelphia, the State of Pennsylvania, have invented a new and improved mode of preventing steam-boilers from bursting, and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
83. lappuse - SIR: In compliance with the request contained in your letter of the...
373. lappuse - Flue hereafter to be built or rebuilt shall be built of sound Materials, and the Joints of the Work well filled in with good Mortar or Cement, and rendered or stuccoed within ; and also...
422. lappuse - The wool had been carded in the common way, and was passed between two cylinders, from whence the bobbin drew it by means of the twist. " This successful experiment induced him to seek for a pecuniary connexion equal to the views that the project excited, and one appeared to present itself with a Mr.
36. lappuse - ... a single broad hoop, and pressed into the undulated form represented, by which it is found to act with uniform energy upon the wedges, until they and the segments become so much worn in the course of time, that the steel spring recovers itself into its original circular figure; d is the frame-work, cast in one piece, with the lower plate of the piston ; e is the...
32. lappuse - ... disappeared, but for the assistance of a watchman whom I engaged to supply water at intervals. At a maximum I suppose the mass of ice was at times about two inches square, and from a quarter to a half an inch thick. The gradual introduction of the water, by aid of the funnel and valve cock, also of the pipe represented in the figure, by which it was conducted to the cavity in the sheet brass, enabled me to accumulate a much larger mass than I could have produced otherwise.
379. lappuse - That the bottom of a floating solid should be made triangular ; as in that case it will meet with the least resistance when moving in the direction of its longest axis, and with the greatest resistance when moving with its broadside foremost.
423. lappuse - Arkwright indicates great inventive talent, even if we suppose that he had seen the former machine ; but the mechanical details of the two have so little in common, that I am induced to think, contrary to the opinion of Mr. Charles Wyatt, that Arkwright had not seen the machine of Wyatt or Paul. It must, however, be admitted, that to contrive and adjust the details of such a machine, though of the greatest practical importance, is a merit very subordinate to that of him who conceived the great principle....
36. lappuse - ... between the two former, for the reception of oil ; these parts are not introduced into the figures. The action is as follows : — as the piston and cylinder wear away by the friction, the circular spring c presses out the wedges b, and these project the segments against the cylinder ; by degrees they are reduced to the dimensions of that exhibited in the annexed figure...
220. lappuse - Consolidated mines, has 1230 feet of its depth below the surface of the sea, while the bottom of the shaft of Valenciana in Mexico is near 6000 feet in absolute height above the tops of the shafts in Cornwall. The bottom of the shaft at the Sampson mine in the...
