... I S arranged in a vertical position on one side of the boiler near the smoke ence an d Arts, on the secondary or residual spectrum found of danger and safety. Some rely on thick glass in the winpipe, attaching it to a vertical supporting plate having a concave side, fit on passing a ray of white light through two prisms of difdows, and some on register stoves; others recommend stone ting the boiler and bolted to it; also having a bearing at the upper end for erent substances arranged to compensate each oth@r for roofs instead of slate and others tell timid people that they a counterSh � ft for driving the pump, said shaft . extendir:g across the top of ESllu Tarran t, Muskegon, MiCh.-In this invention the forward part of the log deck is made inclin8d, so that when a log is rolled past its center it may roll directly upon the carriage, where it is stopped in proper position by the standards in the head block. A wheel or segment of a wheel has an axle which works in short guide slots in the middle part of the log deck. The wheel is preferably in the form of a half wheel or semiCircle, and an axle is arlangedin such a position that the straight oide of the said wheel Improved Stealn Engine Governor. And81's Matson, Quincy, Ill.-In this invention a pipe conducts the steam from the boiler,and is connected with a chamber. The valve and seat are made of metal suitable for the purpose. The cylinder has a flange which fits steam tight into the base flange of the chamber. The cylinder is closed at the top and fits inside the valve. The steampresses equally on each side of the valve, so that it is balanced, and has free motion to regulate the speed of the engine. The top part of the shell ot' the chamber fi ts into the upright bOW, so that the latter can be turned to give the driving shaft any required direction. Improved Hydraulic Motor. William Walter, Arkada, Washington Territory.-This invention consists n the application of the stream or body of water to a vertical ciste"n and cistern valve, which is balanced by a weighted lever, so that,on floating,the water rushes into a horizontal pipe and trough filled with water. The for wa.rd motion of the water, in connection with the closing of the ciEtern valve, produces a forward motion of a piston valve at closed end of hori zontal pipe, which is connected to the machinery to be driven by it. Both the level" power and piston power may be utilized, as desired-the lever power for crushing quarLz and stamping bones, the latter, by suitable transmission, for driving different machines. Iinproved Spring Bottom. In this in ventioD, three bottom rails, preferably, are employed in one bed. The top slats are placed transverBely upon three rows of springs that stand on the rails. Each slat is mortised, near the end, to receive a loop from each spring beneath, except from the middle springs, which have loops that lap around the slats. Strapa are fastened to the head and foot pieces of the bed bottom, and pass throngh the loops of the side row of springs and over"the slats, so that the said straps will serve to prdvent the loops from being drawn down through the mortises of the slats. These several clasps form holders bY.whlch the springs will be evenly held upon the lower rails, and are a very convenient andpractical mode of attachment for the springs, allowing them ready application and removal. Adjustable Treadle for Sewing Machines. Joseph McEvoy, Brooklyn, N. Y.-This invention consists of an arrange ment of the treadle pivot rod, in curved slots in the end frames or other Bupports, for adjusting the treadle toward or from the front of the machine to suit �he operator; the elots are curved to the axis of the crank shaft, so that the distance between the rod and the center remains the same. It is applicable to the table of a sewing machine, lathe, or any other machine to be worked by toot power. Improved Drill Rod Coupling. Robert A. Clark, Petrolia City, Pa.-This invention consists of one sec tion, having a screw threaded portion at the end, of smaller size than the rod screwing into a socket in the end of the other section by a right hand screw, and a sleeve screwing on the two sections by a left hand thread down against a collar on the lower section, by which the joints are locked so that they cannot work loose.
