Title: An Improved Safety Appliance for Centrifugal Governors.
Inventor: MILNER JAMES
Filed: 1897-07-13
Granted: 1898-03-26
Abstract: 16,654. Milner, J. July 13. Centrifugal governors ; safety-gear.-Relates to the means described in Specification No. 12,875, A.D. 1896, whereby, on the occurrence of any accident to the strap or driving-gear of the governor, the latter in its collapse causes the throttle valve to be closed. The present invention consists in arranging such gear so that it becomes automatically re-set on starting the governor again, and does not require a special re-adjustment by hand. The rod by which the throttle valve is operated is shown at A. In order to provide for the depression of this rod when the governor collapses, a spring capable of acting on it through the forked bar C is maintained under compression by a head E resting on a cam. This is moved so as to release the spring whenever one of the governor balls sttikes a projection k. The re-setting is arranged for thus :-By worm gear the wheel M is continually driven from the governor driving-gear and thence the wheel H would be always driven if it engaged therewith. It engages, however, only when not in its " set " position, and is free whenever it is in that position. This is owing to the slide K, by which the engagement is effected, being pushed outwards by a cam-stop Q. The result is that the driving of the governor causes the wheel H to revolve until the mechanism is " set and then fails to drive it any further.

Title: Improved Electro-mechanical Apparatus for the Control of Electric Motors.
Inventor: DULAIT JULIEN
Filed: 1897-07-20
Granted: 1898-07-20
Abstract: 17,142. Dulait, J. July 20. Motors, controlling.-Apparatus for starting, stopping, and reversing electric motors, particularly applicable to the control of electric lifts, is shown diagrammatically in the Figure. M, A, and D are three push contacts for effecting the ascent, stoppage, and descent of the lift, P is a battery, and X is a resistance switch in the armature circuit. On making contact at M, an electromagnet a attracts a lever l carrying plungers, which enter mercury cups b, b<1> on the armature leads, and forming part of the reversing-switch; at the same time the contacts #, #<1> are brought together by the lever and the electromagnet E, becoming excited, attracts a lever a which closes at j, j<1> the field excitation circuit. Solenoids S, S' in the field circuit then actuate the lever B of the resistance switch, and the armature is supplied with current, the resistance being gradually cut out. In order to stop the motor, contact is made at A. On doing this, the electromagnet y is excited, the lever a released, and the excitation circuit broken at p, p<1> and made at h, h<1> in such a manner as to prevent sparking. The solenoids S, S<1> are now inactive, and the switch lever is retracted by a spring R, thus throwing the armature out of circuit. On the switch lever making contact at k, c, the current passes through the releasing-magnets #, #<1>, of the reversing-switch, and finally, on making contact at n, c, the magnet s actuates the lever t and short-circuits the motor. For bringing about the descent of the lift, contact is made at D, on which the magnet z is excited and actuates the lever l<1> of the reversing-switch so as to supply current to the armature in the opposite direction.

Title: A Device for Automatically Lighting and Extinguishing Gas Lamps.
Inventor: HAHN TH
Filed: 1898-04-05
Granted: 1899-03-04
Abstract: 8072. Hahn, T. April 5. Lighting and extinguishing gas.-Relates to a device for automatically lighting or extinguishing any number of lamps from one controlling centre. A receptacle D, having a central gas pipe C, is connected to the service pipe of each burner or burners. A double bell B fits over the end of the pipe C, and dips into the mineral oil in the receptacle to an extent determined by the ring L. By increasing the pressure in the mains, the gas from the pipe C forces the oil down and passes through the triangular apertures 0 into the outer bell and thence to the burner. On lowering the pressure, the oil rises and covers the apertures, so preventing the passage of gas. A bye-pass W supplies a pilot flame constantly with gas. In the modification, shown in Fig. 4, gas forces its way past the bend K, to the burner, when the pressure is increased ; when the pressure is diminished the oil rises and stops the passage of gas past the point K.

Title: Improvements in or relating to Acetylene Gas Generators.
Inventor: KUEPPERS KARL
Filed: 1899-04-20
Granted: 1899-06-10
Abstract: 8339. K³ppers, K., and Schroeder, H. April 20. Acetylene. - An apparatus for generating acetylene in which the supply of carbide is automatically regulated. Consists of a water vessel m, in which is an inner vessel d to which an ascending tube c is attached. Fixed on the top of this tube is the carbide supply hopper a, having a discharge valve e, which is connected by a lever f to a bridge-piece attached to an annular float g. As the float rises, the valve is opened ; as it falls, in consequence of the pressure of gas driving back the water, the valve is closed. The carbide in falling is directed by the conicallyshaped shield h. The acetylene escapes by a pipe i and cock l to a purifier. A second pipe n from the pipe i leads the gas to the upper part of the carbide holder to equalize the pressure in the generator and the carbide receiver. This pressure is indicated by a gauge attached at s. A safety escape pipe, open to the atmosphere, is provided. Above the hopper is a glass tube within which a metal bar x can move. This bar is drawn to one side, and thus held by a hook forming part of a wire the other end of which is connected to an outwardly-curved elastic membrane r. When the membrane is pressed inwards, the grip on the upright rod is released, and the rod falls, a flat plate or ball on its lower end resting on the carbide. By this means the upper end of the rod acts as an indicator of the amount of unused carbide in the holder.

Title: Improvements in or relating to Bottle Labelling Machine.
Inventor: ERMOLD EDWARD
Filed: 1899-08-23
Granted: 1899-10-28
Abstract: 17,099. Ermold, E. Aug. 23. Damping and affixing labels.-Relates to machines for labelling bottles. The pickers P, which are supplied with paste at C, take up a label at E and bring it forward so that a bottle placed over it can be pushed down on to it and then between the wipers F by a plunger D. These pickers P are mounted as horizontal slides, carried by a vertically-sliding plate B on a carriage which is moved backwards and forwards on the guide-bars a by the lever b<18>. As the carriage comes forward, the paste-box C is raised by the lever C<4>, so that the paste roller may supply paste to the pickers. Roughened surfaces on the underside of the carriage engage wheels on the ends of the roller to revolve it, and a pivoted adjustable scraper C<9> regulates the thickness of the layer. When the carriage is over the label holder, the lever b<27> depresses the slide B so that the pickers gather the top label E, and further forward motion brings it under the plunger D. At this position cam rails r' are spaced wider apart, so that the picker slides which bear upon them can open out to let the bottle pass. The bottle is placed in position over the label so as to bear against a gauge plate on the carriage B, and then the plunger D is depressed by the lever D<2> so as to drive it between the spring- protruded guides b<9>, which are mounted on the carriage B just above the pickers P. Below the latter are the wipers F mounted on spring-controlled arms F<1> pivoted on the frame of the machine. The wipers consist of flexible plates, which may have slit edges, and may lie on plates with curved edges; Finally the bottle is received on the elastic band &c. of a forked support. The labels are contained in a holder consisting of rods E<5> adjustable in slotted lugs at their top ends so as to accommodate different sizes. They are pressed upwards by a follower E<8> mounted on a screw spindle E<9>, which works through a feed-nut E<10>, and is driven by bevel gearing from ratchet gear e<7> or a hand-wheel e<6>. The nut only engages one side of the screw, and is mounted on the spring-returned lever E" so that it can be released for adjustment or filling. Fingers e hold the labels at the top, and allow of their separation one by one. The label ratchet feed, picker carriage, paste box, picker-depressing lever, and bottle plunger are all worked from a cam shaft (not shown in the Figures herewith) which is geared to a main shaft with treadle and clutch for starting and stopping.
