Granted: 1913-03-13
Abstract: 9203. Ubbelohde, L. April 18. Resistances.-In a furnace, an oxidizable wire wound on an insulating tube is protected by an outer layer of carbon but is separated from it by a porous insulating layer to avoid shortcircuiting at high temperatures. The wire may consist of an alloy of iron and nickel, containing 25 per cent of the latter metal and having a resistance at 1,000‹ C. only 46 per cent greater that at 20‹ C. ; this enables the furnace to be started at the full working pressure. In the form shown, a wire a is wound on a tube b of glass, porcelain, or the like and is embedded in a porous material which may consist of 27 parts of burnt clay, 10 parts of fibrous asbestos, 63 parts of alumina, and a little water-glass, made plastic with a 3¢ per cent solution of soda, the whole being surrounded by powdered carbon d in a metal case. An air-tight packing f of asbestos sheets at each end of the tube is held by a metal cover. In a modification, the porous insulator consists of a clay tube separated by a space from the wire a.

Abstract: 10,642. Smith, T. L., and Brackenbury, E. W. June 12, 1911, [Convention date]. Tar-macadam, plant for making. - Relates to machines for mixing tar - macadam, in which the materials are heated by hot furnace gases which enter the mixer at the end from which the materials are discharged, and consists in adapting the conduit leading the gases from the furnace to the mixer to swing away from the mixer when this is rotated to discharge its contents. In the form shown, a rotary drum 11 is mounted on trunnions 31 in a frame 30 carried by a truck 10. The drum is rotated by a steam-engine fed by a boiler 14, and hot gases from the furnace of this boiler are delivered to the discharge end of the drum by a pipe 15, which is provided with pivotal elbows 16, 21, and is suspended at its discharge end by a link 22 pivoted to the frame. The pipe is also pivoted to a link 27 turning on a pin 29 on the drum above the trunnion 31 so that, when the drum is tilted forwards, the discharge end of the pipe is swung clear of the end of the drum. The feed-apparatus comprises a bucket 13 into which are loaded the ingredients to be mixed, and a ladle 40 mounted thereon for containing the tar. The bucket is raised by a hoist 36, the rollers travelling on curved tracks 37, 38 adapted to tilt the bucket in its upper position to discharge its contents into the feed end of the drum 11, and the contents of the ladle into a hopper 41. The fire is forced by a blower, preferably driven by steam jets from the top of the boiler, and the speed of the gases in the pipe 15 is regulated by adjusting (1) a sliding valve 18 operated by a lever 19, and (2) a damper 20 in the smoke stack. When the materials in the drum have been thoroughly heated and dried, the tar from the hopper 41, which is heated by the exit gases from the drum, is admitted to the drum, the whole is thoroughly mixed, and is finally discharged by tilting the drum on its trunnions. The pipe 15 is made fire-resisting by constructing it in halves, lined with asbestos, and bolted together.

Abstract: 24,960. Smith, C. Oct. 31. Automatic alarm signals.-In apparatus for periodically testing a battery used in a fire alarm or other circuit, a clock closes the battery circuit through an electro-magnet, which controls a mechanically-operated signal indicating when the current given by the battery is below normal. In the arrangement shown, a clockdriven disk 1 has a contact 2 engaging with two contacts 4 to close the circuit of the battery through an electro-magnet 10. The disk is also formed with a cam surface 3 engaging with a roller on the armature 11 of the electro-magnet. If the current is normal, the armature is held up when the gap 18 in the cam surface reaches the roller, but if below normal, the roller falls into the gap, and a lug 14 on the armature releases a weight or spring to operate a visible or audible signal. Specification 21,059/06, [Class 40, Electric telegraphs &c.], is referred to. According to the Provisional Specification, the electro-magnet may control an auxiliary electric signalling-circuit. In this case the clock-driven disk has two contacts engaging with two separate pairs of spring contacts to close first the battery circuit and then the signalling-circuit. If the current is normal, the electro-magnet opens the signalling-circuit, but if below normal the signalling-circuit is closed by the disk contact, and a bell is sounded or a visible signal is operated.

Abstract: 28,592. Frankiess, S. Dec. 11. Locking nuts.-A self-locking nut comprises two sections which spring apart to bind on the threads of a bolt, and are drawn together by a set-screw or other means to release the lock. The nut is made from a blank having the shape of two hexagonal or square nuts 1, 2, Fig. 4, connected by a thinner piece 5. After the blank is bent over and the nut straightened up, the two parts are clamped together by a setscrew 7, and the nut is then tapped. On loosening the set-screw after the nut has been screwed on to a bolt, the two parts tend to spring apart, causing the nut to bind on the threads. To prevent its detachment, the setscrew is burred over at 8, or a transverse pin engages a cut-away portion. In a modification, the part 5 is omitted, the blank consisting of two hexagons joined along one side. For square nuts, a bar is rolled with two chamfered edges, and the other edges are chamfered in the shearing process; the cut sections are bent over with the sharp edges inwards.

Abstract: 26,273. Pullin, J. P. Nov. 15. Electric appliances.-In electro-medical appliances adapted to be connected, as by a wall-plug, to the ordinary supply mains, means are provided whereby the current is automatically cut off from the working terminals, in the event of the occurrence of a wrong connexion to the supply mains being made. In the arrangement shown in Fig. 1, a movable armature a', provided with a coil adapted to be energized by the main circuit, is mounted between permanent magnets a<2>, and in the correct working position, as shown, connects the positive and negative terminals through two electro-magnets c in series. These electro-magnets, when energized, attract their armatures e, and so complete the operative circuit to the working terminals b. The operative circuit is in shunt to the resistance d, which may be variable or interchangeable, and a second variable resistance b<1> is connected across the terminals b, thus enabling the potential difference between the terminals to be varied or adjusted as desired. If a wrong connexion is made to the supply, the armature a' is turned automatically so as to disconnect the electro-magnets c and to connect the electro-magnets f, which thereupon attract the armature e and so prevent the working circuit from being completed. Lamps g, h, the latter of which may be coloured, may be provided to indicate whether or not the connexion has been correctly made. In the modified arrangement shown in Fig. 3, a polarized armature a<5> is mounted between two electro-magnets a<3>, a'. When correct connexion has been made, the armature is attracted by the electro magnet a<3> and connects the contacts a<6>, a<8>, and a<7>, a<9>, thereby completing the working circuit, which is bridged across the variable resistance b<1> and, as indicated by the arrows, is connected through a reversing-switch to the working terminals. If wrong connexion is made, the armature is attracted by the electro-magnet a' and the working circuit cannot be completed.
