Title: Improvements in Non-refillable Bottles
Inventor: PELTON CHARLES HENRY
Filed: 1903-03-17
Granted: 1903-04-30
Abstract: 6170. Pelton, C. H. March 17. Stoppers; refilling, preventing and detecting.- The top of the neck of the bottle is made flat, and is closed by a cork or other packing-ring C and a cap B, to which is attached a beaded tube D of wood or other material extending downwards into the neck ; the tube rests, by means of a flange F, on a shoulder A<1> in the neck, and is retained in place by a bead H which enters a groove A<11> ; a packing-ring I makes a joint between the tube D and the bottle neck. Inside the tube D, a second tube L, L' is supported frictionally by means of a flange M. A ball valve 0 closes the upper end of the tube L, and a smaller ball valve N closes the upper end of the reduced portion L'. When the bottle is filled and the parts are in position, as shown, the ring C seals the bottle. When the ring is removed, and the bottle is turned on its side, the liquid will flow out from inside the tube D through the openings D<11> and through the enlarged part of the neck. At the same time, air will enter the openings D<1> in the tube D, and pass the valves 0, N into the bottle. The bead E outside the tube D forms an obstruction to the liquid on the upper surface, causing the liquid to follow the bead to the lower side, thus preventing it from entering the openings D<1>. Any attempt to withdraw the tube would cause it to break at the openings D<1>, or if successfully withdrawn, a wooden ball P placed on the tube L<1> would be drawn off into the bottle and expose the fact of the removal. Any attempt to refill the bottle with an air pump will cause the tube L, L<1> to rise, so that the cork or other valve J, which is located normally below the tube, closes the tube D, and thus prevents any liquid from entering the bottle.

Abstract: 8468. Mingay, N. A. April 14. Lamp and gas brackets.-An electric light fitting for bakers' ovens, in which the lamp may be readily taken out and renewed at the normal temperature of the oven, comprises an outer tube A, Fig. 1, fixed to the oven wall and an inner tube C, fitted with a lamp holder D and temporarily secured to the outer tube A by the pin c which slides in a slot in the outer tube. The inner tube C contains two metallic rods G which connect the spring terminals F with the terminals of the lamp, against which terminals they press. The rods G are insulated and kept in place by porcelain insulators E' and asbestos discs J. To insert a new lamp in the fitting, the metal cap L is unscrewed, thereby enabling the inner tube C to be pressed into the outer tube until the pins c can be turned in the curved slots and released therefrom. The inner tube C is then withdrawn and a new lamp fitted in the holder. In a modification, the outer tube A is made large enough to allow the withdrawal through it, from outside the oven, of the inner tube C and lamp. For this purpose the cap L is secured to the inner tube C.

Patent GB-190320147-A (GB)
Title: Improvements in Series High Pressure Centrifugal Pumps.
Inventor: JACKSON BYRON
Filed: 1903-09-18
Granted: 1904-01-14
Abstract: 20,147. Jackson, B. March 4, [date applied for under Patents Act, A.D. 1901]. Centrifugal pumps.-Relates to the construction and arrangement of series centrifugal pumps, and an automatic adjustable balance for the end thrust on the shafting. Fig. 1 shows a vertical, and Fig. 2 a horizontal, type of the pump in sectional elevation. These consist of two or more chambers A, A' which are exactly similar, and another chamber 2, which is connected to the tangential delivery pipe 5<1>. The impellers 3 are of the enclosed type, and of the form shown in Fig. 3, and are all keyed on the same shaft. The water passes from the suction pipe through the first set of impellers and then through the curved water-ways 10 to the next set of impellers. These water-ways are of the shape shown in Fig. 4, so as to prevent any change in the direction of the whirling water. In the horizontal form, shown in Fig. 2, the impellers have apertures 19<1> in them, so that the pressure of the inflowing water is balanced on both sides of the impeller. To compensate for the varying pressure caused by the end travel of the pump shaft changing the clearance space between the sides of the pump case and propeller, a plug valve or sleeve 6 is fitted on the end of the shaft. This plug is arranged to be advanced or retracted by the screws 7, 7<1> according as more or less back-pressure water in the chamber 8 is desired to be liberated in order to restore or maintain equilibrium. In the vertical type, the water cushion in the chamber 8 serves to sustain the weight of the running parts. Whenever the pressure in the chamber 8 exceeds that on the opposite side of the impeller, the shaft moves towards the suction end, and some of the water escapes. When the pressure exerted from the suction end is greater than that from the discharge end, the shaft moves towards the plug, thus closing the chamber 8, and further motion is resisted ; the impellers are thus automatically kept in their central position in the pump-casing.
