Title: An Improvement in Locks and Keys for Doors, Cupboards and the like.
Inventor: DAVIDGE HENRY THOMAS
Filed: 1903-02-25
Granted: 1903-12-31
Abstract: 4421. Davidge, H. T. Feb. 25. Locks, key, latches.-Relates to locks for doors, cupboards, &c., in which the key arranges the tumbler or other mechanism while the bolt is operated by a handle. The tumblers T, Fig. 5, are pressed upwards by the lever L actuated by the strong spring J. On turning the handle H, the lever L is depressed and the tumblers descend under the action of the weak springs F to positions determined by the notches on the key, Fig. 3, inserted with the notches upwards in the keyhole W, in which positions the stump D on the bolt can pass through the gates Z. The bolt is operated by the follower G. There is a separate keyhole W on each side of the lock, neither keyhole extending through it. The same key is used on both sides, the notches engaging separate sets of edges on the tumblers. The end of the bolt may be bevelled, forming a latch operated by a spring, the same handle H being used for the latch and lock. Fig. 6 shows a modification forming a spring nightlatch. The bolt is in two separate parts U, V, both acted on by the spring Y. The part U has a bevelled end Q, and can be withdrawn from the staple by the knob P inside the door, without moving the part V. If the part V is operated by the handle H and the key on the outside, the bolt moves as a whole. The stump D does not leave the gates on the left-hand side, so that, when the pressure on the handle is released, the bolt is shot by the spring Y. Any arrangement of tumblers may be used in the locks, and, in some forms of the invention, the key can only be withdrawn when the door is fully locked or unlocked. A small stop connected to a knob on one side of the door may be used to operate the lock without a key. In the Provisional Specification, it is stated that the keys are made of thin strip aluminium or other metal, and that they may be folded together like the blades of a knife.

Title: Improvements in connection with the Automatic Feeding of Steam Boilers by Gravitation under Steam Pressure.
Inventor: PICKERING WILLIAM JOSEPH
Filed: 1903-10-24
Granted: 1904-07-28
Abstract: 23,027. Pickering, W. J. Oct. 24. Feedwater, supplying.-The apparatus for the automatic feeding of steam boilers by gravitation under steam pressure, as described in Specification No. 24,040, A.D. 1902, is modified so as to be applicable to cases where the water supply reservoir is situated below the boiler. An upper open tank A and a lower closed tank B, preferably of cylindrical form, are both mounted above the boiler, the water supply tank C, Fig. 4, being below the boiler. When the water in the tank B falls below a certain level, a float operates, by means of a double-action steam cylinder, a three-way sliding valve K, which shuts off communication between the boiler and the tank B, and allows the tank C to communicate with the tank B through the pipes T, J, J'. As the steam from the tank B escapes through the pipe J, the branch pipe J<3>, which is provided with a check valve M' having a downward flow, and a silencer N, the float valve D, which has a limited movement, allows a small quantity of water to flow from the tank A through the pipe E, which is fitted with a check valve E', to the tank B. The vacuum thus formed draws the valve D on to its seat and causes the water in the tank C to rise through the pipe J<2>, which is provided with a check valve M having an upward flow, and enter the tank B through the pipe T, which terminates in a spreader. When the tank B is filled with water, the float therein, which is provided with a counterweight R, operates, by means of the steam cylinder, the valve K so as to allow the tank B to communicate with the steam space of the boiler through the pipes O, T, and with the water space of the boiler through the supply pipe O<1>. The water then flows from the tank B into the boiler. Fig. 2 shows a modification of the valve D in which a lever H raises the valve when the suction pressure in the pipe E is allowed to fall.

Abstract: 12,228. Hopkinson, J. June 3, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Adjusting; bearings.-To enable weighing-apparatus, and especially spring apparatus, to register accurately at all temperatures, heat-compensating bars are employed. In the form shown, a platform or receiver A is supported on knife-edge bearings h<3> on a lever B pivoted at b to a standard C, and connected by the load rod G to a spring E which is attached to the indicating-device F. The effective leverage of the platform lever is varied, to neutralize or compensate for changes due to variations of temperature, by a bar H connected to an expansion B' of the lever B, and pivoted to a lever H<1>, pivoted to the lever B at its opposite end, the longer arm of which is pivoted to a second bar H<2>. The other end of the bar H<2> engages a cross bar or frame H<3>, carrying the platform pivots and adapted to slide on the platform lever. The pivots work in slots H<4> in the lever, and ball bearings I are provided. A spring I<1> holds the bar H' in position. The bars H, H<2> are formed of a metal having a high heat expansion, such as zinc, and neutralize the expansion or contraction of the other parts of the apparatus. In a modification, the bar, such as H, is connected at one end to the top side of the lever, while its other end is connected by a short lever, pivoted to the platform lever, to a second bar beneath it. This second bar co-operates with a sliding bearing on the forward part of the platform lever for the load rod. In another form, two expansion rods and their connecting-lever are arranged in the same plane beneath the platform lever, and are connected together by knife-edge or point bearings, being maintained in contact by a spring. Instead of two expansion bars, a horse-shoe arrangement, formed of plates of metal having different coefficients of expansion, is used, one end being directly connected to the platform lever and the other to an extension of the bearing for the pivots of the load connection.
