Abstract: 4457. Schade, W. March 8. Locks, electrically-controlled.-Relates to means for electrically releasing the spring latch bolt a<1> of a door lock, and so enabling the door to be opened from any desired part of the house, during the time that the ordinary locking-bolt a is retracted. The bolt a' is connected by the spring f<11> to the cylinder B, which has a projection B' engaged by the lever H, when the latter is locked, as shown, by the armature R of the electromagnet E. The cylinder is also controlled by two springs f, f<1>.

When a push in the circuit v, w of the electromagnet is closed, the lever H is released, and the bolt a' is retracted by the spring f<1> ; the ordinary electricbell fittings may be employed. As the door opens, the bolt a<11> releases the spring f, which then throws both bolts forward, and resets the bolt a'. When the door is closed, the bolt a<11> is pushed back by the staple N to the position shown, so disengaging the spring f from the bolt a<1>. The bolt a' may also be opened by the knob K, or by means of a key.

Granted: 1901-03-16
Abstract: 6997. Hill, W. T., and Evans, W. April 14. Beer and other beverages, raising. - The gas pressure required is not admitted to the barrels or casks, but only to a vessel A intermediate between it and the delivery tap. At the bottom of the vessel A there is a pipe containing check valves band o to connect it to the barrel and the tap, while at the top of the vessel there is a vent pipe l and the gas under pressure enters by a pipe k. A pair of valves j, i in the vent pipe and the gas - pressure pipe respectively are connected by a lever h from which there hangs a rod e forming both a weight and a guide for a float g. The liquor raises the float till it strikes a pin e<1> on the rod, and so operates the valve lever to close the vent valve and open the pressure valve. The liquor is then forced out, the vent pipe remaining closed till the float has descended to a pin e<2> in the rod. The vent pipe l ends in a #-piece m, one branch of which is connected to the gas space of the barrel. A differential valve m<2>, m<3> in this #-piece allows some of the gas under pressure in the emptied vessel to force its way into the barrel.

Title: Improvements in Boiling and Vaporising Fluids by Electricity.
Inventor: SAYER ROBERT COOKE
Filed: 1900-04-20
Granted: 1900-08-11
Abstract: 7314. Sayer, R. C. April 20. Stills and like closed evaporators; heating, special means for; heating, regulating. - An electricallyheated apparatus for evaporating a liquid under pressure is partly shown in Fig. 2. The liquid is supplied to a dish 25, which is heated by an electric current passed through it between two conductors, connected with the secondary of an electric transformer. The conductors support the dish in a closed vessel 1. The vapour produced is discharged through a pipe 3 or a safetyvalve 2. The liquid is supplied to the dish from a vessel 38 by two valves 36, 39, connected by a link 42 so that one is closed when the other is open. Another valve 9, connected w i t h the link 42, connects the upper part of the vessel 38 with the lower part of the vessel 1, when the valve 36 is open. These valves are operated automatically by a float 26 in the dish, either mechanically, or by electromagnetic apparatus illustrated, or by vapour pressure from the vessel 1. In the construction shown, when the float falls it closes a circuit containing a solenoid 43, which moves the link 42 and valves in opposition to a spring ; the float is connected to a lever 28 with a plunger 30 to close and open the circuit. When the float rises, another plunger on the lever 28 closes the circuit of an electromagnet, which then closes a main switch, to supply current to the primary of the transformer. The varying vapour pressure in the vessel 1 acts on a piston in a lateral tube, not shown, in opposition to a spring, to move an arm over the contacts of a rheostat in the primary current of the transformer, and so reduce the current as the vapour pressure increases. The spring is adjustable by a screw. In a modification. the float 26 and switch 28 are placed in a small separate vessel, connected by two pipes with the dish and the upper part of the vessel 1.
