In the lower ends of thelegs are balls provided withstems or shanks enteringholes in the bottoms of thelegs, so that the balls canbe readily adjusted to varythe height of the stool tosuit the child. The childcan be readily placed with-in the ring by swingingout the removable sec-tion, and when the childis in place the section is closed and fastened. This avoids the necessity of placingthe child in the ring feet foremost, and avoids the risk ofinjuring or breaking its limbs. The invention has beenpatented by Mr. Qustav Peterson, of Galveston, A Ship Bitest by Wet Rice.—The Italian ship Pran-cesca, laden with rice, sprang a leak and put into port atEast London, May 11. She was promptly pumped out anda large force of men were set to work to unload her. Therice was in bags and the work was pushed with all speed;yet the wet rice swelled so rapidly that the ship was vio-lently burst asunder May 1§. © 1882 SCIENTIFIC AMERICAN, INC October 28, Mxmtxiu %mnum. 281 ENGINEERING INVENTIONS. Mr. James Mallen, of Wellsville, O,, has patented an improved pulley for driving light machin-ery. A pulley made in skeleton form is keyed to theshaft, and a loose pulley consisting of a tire like banasurrounds it and revolves in the same plane. On theinside of the band are notches that are right angled onone side and inclined on the other, into which radialarms are forced by means of levers, and a sliding collaron the shaft to attach it to the fixed pulleys.
