Title: Improvements in Electric Gear for Controlling Lifts or Hoists
Inventor: BJOERNSTAD JOERGEN
Filed: 1901-05-01
Granted: 1902-04-17
Abstract: 9019. Bj÷rnstad, J. May 1. Motors, controlling.-Relates to electrically-controlled lifts or hoists, in which a control switch operated by a push-button or the like is provided at each floor, and also similar corresponding switches in the car. Fig. 2 is a diagram of part of the circuits, showing the switch at one floor and the corresponding switch in the car D*. Each switch is normally held by a spring c so as to connect the contacts d*, d, and, when operated by the button a, disconnects these contacts, and connects contacts e*, e, the current which then flows energizing an electromagnet g, which holds the switch on the contacts e*, e. With the switches in their normal position, there is connection through all the contacts d*, d, both at the floors and on the car, through a wire E' extending the length of the well. The wire E<1> is connected at both ends to the negative main, the connection from the upper end being through the electromagnet which starts the motor so as to bring the car down, and the connection from the lower end being through the electromagnet of the up switch. The positive main is connected to all the contacts e*, and all the contacts e are connected through the magnets g to a wire E extending the length of the well, and connected, at the landing where the car is, to the wire E' by the contact E* on the car. On pressing a button a at a floor above where the car is, or a corresponding button on the car, the continuity of the wire E<1> is broken at a point above the car, and consequently the current (which reaches the wire E<1> through the contacts e*, e and magnet of the operated switch, wire E, and contact E*) leaves the wire E' by its lower end, and actuates the up switch. Similarly, if the button pushed is below the car, the current flows from the upper end of the wire E' and actuates the down switch. On the car reaching the desired floor, the magnet g of the switch which has been operated is short-circuited by a contact H* on the car, and the control circuit therefore broken. This short-circuiting device comprises contacts h<3> extending the length of the well and each corresponding to a particular floor, and being engaged by its own contact H* on the car. Each contact h<3> is connected to the two magnets g of its floor, and, at the floor, it is interrupted and its place taken by a contact h<3*> connected to the corresponding contacts e. A contact H* can thus short-circuit either the magnet g of its floor switch or the magnet g of the corresponding car switch. In a modification, the magnets g of the floor switches are short-circuited by a single contact on the car, and each of those in the car by its own contact fixed in the well. The positive lead to the contacts e* may pass through switches n controlled by the well doors and car door.

Title: Improvements in or relating to Steam Engines
Inventor: CLARK PHILIPPE LYONS
Filed: 1902-02-17
Granted: 1903-05-16
Abstract: 4007. Clark, P. L. Feb. 17. Exhaust steam, return- ing to boiler.-The object is to complete the utiliza- tion of the latent heat of the exhaust by returning it to the source of supply. In the arrangement shown, A is a steam generator, C the engine, and B a steam chamber or reservoir. The steam chamber B is first charged with steam from the generator and thereafter supplies steam to the engine. The exhaust from the engine is led back into the steam chamber or reservoir through a coil D, and is forced in by an injector E fed with live steam. In the reservoir B is a pump G, sup- plied with steam therefrom and discharging its exhaust into the main engine exhaust pipe, which draws water of condensation or steam, as the case may be, and returns it to the generator A, so as to maintain a constant difference of pressure between the generator and the reservoir. Congestion of the reservoir B may, if slight, be relieved by a safety-valve, or may be prevented by the use of a reservoir B of variable volume with an auto- matically-adjusted differential piston as shown in Fig. 2.
