Inventor: STATTER JOHN GRICE
Filed: 1899-05-02
Granted: 1900-03-31
Abstract: 9160. Statter, J. G. May 2. Instantaneous generators; feedwater, supplying.- Relates to engines working in a closed circuit, in which the vapour is produced in a generator of the flash type. The arrangement of one form is shown in Fig. 1. The vapour from the flash generator A, after doing work in the engine, is liquefied in the condenser C and stored in the tank S, suitable air traps being provided. From the tank the liquid is drawn by a pump P, worked from the engine shaft through the mediation of a spring M, whereby the maximum liquid pressure is determined, and is forced into a spring accumulator K set to a lower pressure than that of the pump. The liquid is fed into the generator from this accumulator, which is also adapted for use in starting the engine. In another form of the invention, the pump, instead of being driven through a spring, is provided with a bye-pass operated by the accumulator plunger, whereby, whenever the latter is thrust beyond a certain point, the liquid pumped is allowed to flow back to the suction pipe.

Abstract: 2272. Edwards, W. R. Feb. 1. Driving-gear for boat propellers ; screw propellers; steering-gear.-Electric boats and launches are fitted with non-reversible motors driving screw propellers having reversible blades. Figs. 1 and 2 show a combined switch and reversing-wheel. The bar b of the switch is connected to, but insulated from, the spindle carrying the hand-wheel, and has at each end a brush e. In the position shown, these brushes are out of contact with the pins f, and the motor circuit is broken. At this time the blades of the screw are in their inoperative positions. When the wheel is rotated to turn the blades into the forward or backward position, the brushes e move on to the pieces f. Figs. 3, 4, and 5 show an arrangement in which a hand-lever a replaces the wheel, and is also used to steer the vessel. It is hinged at g in a swinging frame k, which, by means of cords 2, 3, actuates the tiller, and it is connected to a tube l, which surrounds the screw shaft k and rotates the blades of the screw in any usual way. The lever has a projection u on which is pivoted a switch lever v moving over a contact-segment t. When the lever is in its mid position, a projection y on the locking- rod r lifts the brush w off the contact-segment, and breaks the motor circuit. The blades of the screw are preferably narrow and flat, so as to propel equally well in both directions.

The oil &c. is placed in the tank 1, Fig. 1, which is heated by means of a solution of calcium chloride or the like in the tank 2 above the fire 3. Alcohol vapour from the alembic 8 is discharged through the perforated ring 11, and passes away through the filtering-basket 13, containing potash, to the condenser 15. After the alcohol has acted for a sufficient time, the supply is shut off, and superheated steam is admitted through the pipe 19, a current of hydrogen may be used with the steam. Finally, the refined oil is drawn off, and filtered through animal charcoal with or without carbonate of magnesia. In a modified form of apparatus, the fatty matter &c. dissolved in benzine, or sulphide of carbon is placed in the steam-heated alembic 26, Fig. 2, the benzine &c. is condensed in the coil 27, and the fatty matter &c. is pumped into the purifier 29. Steam supplied from the generator 31 enters through the pipe 32, and, after passing through the purifier 29, is condensed in the serpentine 35. Alcoholic vapour produced in the alembic 36 is passed through the purifier 29, and after condensation in the serpentine 35 is returned to the alembic 36.

Title: Improvements in Fluid Pressure Bearings for the Vertical Shafts of Centrifugal and other Machines
Inventor: MACFARLANE JAMES WRIGHT
Filed: 1902-06-30
Granted: 1903-06-18
Abstract: 14,483. Macfarlane, J. W. June 30. Step and vertical-shaft bearings; lubricating.- In hydro-extractors and other centrifugal &c. machines, oil or other suitable fluid under pressure is substituted for the ordinary footstep bearings, as described in Specification No. 16,367, A.D. 1901. In this invention, the port or ports for permitting the escape of fluid should the supported spindle rise too high are arranged on the inlet or pressure side, instead of the escape side, as in the abovementioned Specification. Fig. 1 shows the invention as applied to a machine with a hol'ow spindle, such as is described by reference to Figs. 5 and 6 in the above-mentioned Specification. The oil, on admission, passes down the inner spindle and, by way of the port D and passages, to the chamber C. The outer spindle is raised clear of the braking-device, and in rising cuts off the oil supply to the chamber C. The spindle comes to rest in such a position that the leakage from the port D is sufficient to maintain the pressure within the chamber C. If the pressure becomes too great and the outer spindle rises too high, the port E comes into communication with the chamber C, such port being connected to the oil-return port and allowing some of the fluid to escape. The invention is also described as applied to machines having solid spindles supported either at the lower or upper ends, such machines being described in the abovementioned Specification by reference to Figs. 1, 2, 3, 4, and 7, and Fig. 8 of the drawings.
