Inventor: WINKLER HERMANN
Filed: 1897-07-31
Granted: 1898-06-11
Abstract: 18,023. Winkler, H. July 31. Lighting and extinguishing gas.-Relates to gas cocks designed to increase the size of the pilot flame when the main burner is extinguished, and to allow of several jets of a cluster burner being lit independently of the remaining jets. The gas supply through the bye-pass channels e, d, Fig. 1, to the pilot flame is increased when the main burner is extinguished by gas traversing the channels d<1>, b<1>, d, Fig. 2. The screw g controls the normal, and the screw h the augmented, gas supply to the pilot flame. Figs. 3 to 6 show the various positions of a cock for controlling several jets of a cluster burner. The supply pipes b<o> and i respectively communicate with different jets in the cluster, and an independent bye-pass passage d is provided.

Granted: 1898-01-08
Abstract: 21,248. Johnston, W. F., and Clokey, W. J. Sept. 16. Cultivators.-Relates to means for raising or for applying pressure to the sections carrying the tines of cultivators. The sections D are pivoted in front to the main frame bar A, and are connected to arms M on a square shaft I by means of the arms N and chains m. Additional pressure is exerted on the sections D by means of a flat spring C<1> secured to a tubular cross-bar C, having an operating-arm P connected by the slotted link p to an arm 0 on the square shaft I. The seat standard H is pivoted to a casting F, to which the draught-pole is secured, and is further supported by links K, K, adjustably secured to arms J, J on the square shaft I in such a way that the weight of the driver tends to counterbalance the weight of the sections when they are raised by operating the square shaft I. The shaft I is operated by a hand-lever Q and eccentricallymounted toothed segments. When the lever is rocked in one direction the sections are raised, and when rocked in the opposite direction the crossbar C is also rocked, thus putting additional pressure on the sections.

Patent GB-189823973-A (GB)
Title: Improved Pantographic or similar Apparatus.
Inventor: PUTZ SEBASTIAN
Filed: 1898-11-14
Granted: 1899-12-14
Abstract: 23,973. Putz, S. Nov. 14. Pantographs.-The apparatus is principally for the use of sculptors for taking points from a model and plotting it on the work. It may reproduce to the same scale or at any desired ratio, or it may give a reversed copy. The whole apparatus may be turned about a conical pivot 7 on a stand 4, the movement being limited by adjustable arms 12, 13 striking an adjustable stop 5. The limiting positions bring the point of the marker 34 over the corresponding points on the model and work. A rod 23 slides in guides 22, and the marker 34 slides in guides 33 in a piece 31 which rotates on an axis meeting the axis of the rod 33 at right-angles. The arm 29, on which the piece 31 is pivoted, rotates on the axis 30, while the carrier 21 of the guides 22 turns on an axis x, the movement being limited by a stop on the arc 20. For reproducing to scale, the marker in one limited position is adjusted to a point on the model, the parts clamped in position, and the whole instrument swung on its pivot 7 to the other limiting position. For enlarging, the movement is similar, but the rod 23 is pulled out a certain amount, indicated by a scale, and the marker slid down from the position shown till the stop 35, adjustable according to the scale, strikes the stop 33, before the point on the work is plotted. For reversing, the marker is turned on its axis 30 through 180‹ before plotting the point on the work.

Granted: 1899-05-06
Abstract: 6126. Reynolds, H. S. March 21. Boilers and water-heaters.-Relates to means for attaching the ends of boilers and other receptacles to their bodies. The head B is made with a plain flange which enters the plain end of the body A as shown in Fig. 4. A jointing-ring C, Fig. 2, is then applied, and the edges a, b of the body and head are worked into the groove 5 of the jointing-ring C. The projecting flange 3 of the ring C is then bent down all round as shown in Fig. 1, locking the edges a, b in place. The shoulder 6 on the ring C enables the head to transmit end-pressure to the body. The ring may be attached to the head before being attached to the body.
Patent GB-189918903-A (GB)
Title: Improvements in Automatic Fire Extinguishing Apparatus.
Inventor: KENNEDY ALBERT EDWARD
Filed: 1899-09-19
Granted: 1899-11-04
Abstract: 18,903. Kennedy, A. E. Sept. 19. Sprinklers, autnmatic; extincteurs; alarms, fire.- Relates to a system of automatic sprinklers connected to a tank resembling an extincteur in construction, and also to the street water supply. The sprinkler heads 16, in which the valves are supported by a lever tied up with fusible wire, are mounted on the horizontal part of the pipe 2. In case of fire, the valves are opened owing to the fusion of the wire. This allows compressed air, with which the pipes have been charged by the hydraulically-actuated pump 14, to escape. The pressure on a flexible diaphragm in the casing 10 being also released, a piston-rod 11 is retracted, thereby releasing a trip lever 9 and allowing the acid bottle inside the tank 1 to fall and discharge its contents into the soda solution. The chemical solution and gas are now forced through the pipe 2 to the sprinklers 16. When the pressure in the tank 1 has fallen below a certain amount, the pressure in the receptacle 23, which communicates with it through a non- return valve 26<a>, also falls, and allows the bellows 23<c> to collapse, thereby opening a valve 24<a> which turns on the street supply to the sprinklers. An electric alarm, which may be local or at a central station, is started by the retraction of the piston-rod 11.

Granted: 1899-12-02
Abstract: 18,968. Thompson, W. P., [Sinding-Larsen, A.]. Sept.20. Incandescent lamps.-A carbon or other filament is mounted in an exhausted U-tube, in the ends of which the leading-in wires are sealed, and which contains a drop of mercury. Current is at first supplied to the lamp through a resistance, or lamps are at first connected in series instead of parallel, until the mercury volatilizes. Instead of using mercury, the lamps may contain argon, nitrogen, or other indifferent gas, under considerable pressure, which may be four atmospheres, when the lamp is in action. It is stated that filaments can be heated to a very high temperature in such atmospheres without volatilization.

Title: Improvements in Appliances for Adjusting and Working the Shutters and Diaphragms of Photographic Cameras.
Inventor: WATKINS ALFRED
Filed: 1900-03-27
Granted: 1901-03-09
Abstract: 5737. Watkins, A. March 27. Exposures, determining; shutters; lens fittings.- Relates to a shutter combined with a slide-rule by which the time of exposure is calculated from the necessary data, namely, size of diaphragm, sensitiveness of plate, and intensity of light. The sensitiveness of the plate, and the intensity of light, are represented on two movable logarithmic scales a and b. The figures representing these factors in the particular case are first brought into coincidence by moving one of the scales, and then both scales are moved together until the index points on a and b indicate the required diaphragm aperture and time of exposure. The slide a is connected to a rack which gears with a pinion fixed to the diaphragm plate, and thus brings the required aperture opposite the centre of the lens; or the diaphragm may be set by hand. The slide b is connected to a rod m, which is tapered so as to regulate the exit from the cylinder of an air brake by which the speed of the shutter is regulated. The shutter consists of two spring-actuated sectors o, c, one of which o opens the lens, and the other c closes it, both being simultaneously released by pressing the button w against the lever x. The time which elapses before the sector c closes the lens is controlled by the air piston which is geared to the sector by the rack h and pinion i.
