The following inventions have been patented this week, as will be found by referring to our tist of Claims :— MACLULM FOR CUTTING GLAZIER'S POINTS. —This machine (the Invention of J. G. Baker, of New Brunswick, N. J.) is intended to cut the triangular pieces of sheet metal used by glaziers to hold the panes of glass in their place while the putty is hardening, and called " tins" or " points." The invention consists in the employment of a rotating drum with cutters attacued, a stationary die or bolster, and feed rollers, so arranged that the tins or peints may be cut from the sheet metal with great rapidity, and with but a small expenditure of power ; and also for cutting shoe nails and other Hrticles of triangular form. MECHANICAL TOLLER.—J. Bartholomew, of Dundee, N. Y., has invented a novel device for gathering toll from grists. The invention consists in having a series of chambers formed in a rotating cylinder, and provided with valves, the chambers, as the cylinder rotates, passing under a spout, and receiving the grain, and the valve being so operated that the necessary toll will be discharged from one or more chambers into a separate recep.tacle, while the grist will be discharged from the other chambers either directly into a hopper or into any other proper receptacle. GAS RETORT.—This invention consists in a certain construction of a retort, by which a very large heating surface is obtained, for the generation of gas, and convenience is afforded for cleaning out as often as necessary. There is also a contrivance attached for regulating the supply of material to the retort. W. H, Lanbach, of Philadelphia, Pa., is the inventor. DEVICE FOR HOLDING SHEEP. — When sheep are being sheared they get nerveus and move about very much, thus hindering the operation, and endangering themselves, by causing the shears to run into their bodies. To prevent this, J. E. Chapman, of Castile, N. Y., has contrived a concave bed combined with rotating adjusting wheels, so arranged that they hold the sheep perfectly secure while being sheared, withont hurting it. ICE PITCHER.—The ice pitchers now commonly used are deuble-walled ; this invention consists in surrounding an ordinary double-walled pitcher, or other vessel for holding liquids, with an addltionHI shell, arranged concentrically with it, and arranging above the double top and bottom of the common pitcher correspending additional disks, i n such a manner as to interpose an additional air space to the entrance of the external heat, and thus more thoroughly preserve the temperature of the contents of the pitcher, and at the same time keep the exterior shell or wall at such a relative degree of temperature with the exterior atmosphere as shall prevent the condensation of the moisture on the outer surface, and the consequent unpleasant dripping of water. G. W. Smith, of Hartford, Conn., is the inventor of this excellent construction of pitchers, and' they are manufactured in every variety of design by Rogers, Smith Co., at Hartford, Conn.v who also have an office at No. 170 Broadway, New York. WHISTLE SIGNAL ALARM.—A. E. Turnbull, of Springfield, Ohio. This invention is intended to Hnnounce the arrival of a train near a station or other place, in order that the officials may be on the alert. It consists in arranging and combining two levers in front of the locomotive, and connecting them together, and terminating their lower ends in such reIHtion to uprights fixed between the rails, where it is designed to blow the alarm whistle, as to cause one lever to open the orifice from the boiler to the whistle, and the other to close ] the lame orifice, and thus close all communi- : cation between them.
