Title: Improvements in Electric Accumulators.
Inventor: LEIMER EWALD
Filed: 1898-07-19
Granted: 1899-03-04
Abstract: 15,801. Leimer, E. July 19. Drawings to Specification. Secondary batteries are constructed with electrodes arranged as follows :-Next the wall of the receptacle is a plain negative electrode of the PlantÚ type, to which the negative wire is connected while charging. In contact with this is an ebonite comb or grid, followed by a 'discharging' negative electrode of compound material &c., to which the negative wire is connected while discharging. A thin comb-like plate of an alloy of lead and antimony, which will resist the acid, presses against the discharging-electrode, and next in order comes a perforated ebonite plate which separates the negative half of the cells from the positive. Another comb-like metal plate, a discharging electrode, ebonite comb, and PlantÚ-type positive electrode used for charging, follow in succession, and in this way a cell with any desired number of plates is built up. It will be understood that the discharge is taken from plates which lie between the electrodes used for charging, and across which the charging-current passes. Wear and tear of the pasted or compressed plates is stated to be prevented to a large extent in this way, and the charge and discharge rate is increased.

Granted: 1901-12-07
Abstract: 1983. Lock, W. H., and Lawless, P. C. Jan. 29. Linotype machines.-Relates to means for wiping the mouth-piece of the metal pot after each cast, and has reference more particularly to the Mergenthaler linotype machine, Specification No. 14,582, A.D. 1890. Fig. 3 shows a front elevation, in which the mould-wheel O is shown in dotted lines. A stud 6 projects rearwardly from the mouldwheel, and is adapted to engage with a wiper-arm 3, which carries at its outer end a leather &c. wiper 4. The arm 3 may be a radial continuation of a spiral spring 1 surrounding the mould-wheel bearing o<2>, or it may be secured at 15 to a loose sleeve 11, to which one end of the spiral spring is also attached. The other end of the spring is secured at 2 to the arm o<3>, which springs from the mould-wheel slide o<4> and carries the bearing o<2>. While a linotype is being cast, the arm 3 is in its fully retracted position, and the wiper 4 rests against the pad 5. The stud 6 is at this time immediately behind the arm, and, when the mouldwheel commences the three-quarter revolution which brings the linotype to the ejecting point, the stud carries the arm 3 forward against the tension of the spring 1, and causes the wiper to traverse the mouth-piece v of the metal pot. The wiping being complete, the arm 3 encounters a camshaped horn 7 mounted on the arm o<3> and is drawn rearwardly until it escapes from the stud 6 and flies back to the stop 5, the mouth-piece being wiped a second time in the return movement. In a modification, the coiled spring 1 is eccentric to the bearing o<2>, its centre being below that of the bearing. The stud 6 makes contact with an adjustable contact-piece extending forwards from the arm 3. Owing to the eccentric position of the spring, the contact-piece slides downwards relatively to the stud, and ultimately escapes from it.
