Patent GB-189915895-A (GB)
Title: Improvements relating to Magnetic Compasses.
Inventor: HADDAN HERBERT JOHN
Filed: 1899-08-03
Granted: 1900-10-03
Abstract: 15,895. Haddan, H. J., [Heit, C.]. Aug. 3. Compasses, magnetic.-Relates to a registering and signalling compass. The bowl a has placed around it a series of insulated contact-strips b connected to the terminals n and thence to the battery and to the registering &c. apparatus. These strips are placed symmetrically about a strip marked zero, at first being very narrow for marking degrees, but getting gradually wider as they get further from the zero, where delicate observations are not required. The card A, from which parallel magnets E and copper counterweights G are suspended, is supported on a centre D resting in a mercury cup connected to the battery. A wire leads from the cup to one of two rollers R between which rests a pointer M, preferably a straw with copper armatures or thimbles 10, 11 at its ends. The pointer is placed east and west on the card, and it terminates in a palladium spiral S which normally is just out of contact with the strips b. When setting a course, the bowl is swung round by bevel and other gear (not shown) operated by an external handle, till the zero strip b is opposite the spiral S ; the wires from the terminals n pass down a hollow axle, which is simultaneously rotated so that the wires do not get twisted, and they end in insulated rings from which the current is taken by brushes The bowl is suspended by spring devices from a ring running on rollers on a rail. For delicate adjustment, the gear may be turned by speed-reducing gear to which the handle may be fitted. At stated intervals, say, every 30 seconds a time switch completes circuit for a magnet which operates bellows connected by a pipe with the bellows F dropping a weight P upon a weight X and actuating the counterweighted bell-crank lever O. This thrusts forward the pointer M between its guide-rollers R, the lower of which is fitted with a projecting guide-finger, so that the spring S makes contact with the strip b then in front of it, and actuates the register and signalling apparatus. The signalling- apparatus consists of a series of bells of different tones.

Title: Improvements in Sheet Feeding Apparatus for Printing and the like Machines.
Inventor: CLEATHERO EDWARD THOMAS
Filed: 1899-09-13
Granted: 1900-09-08
Abstract: 18,451. Cleathero, E. T. Sept. 13. Feeding sheets.-Fig. 1 shows an arrangement in which the pile of sheets 1 on the table 2 is fed by the usual feed-rollers 3, and 17 is the usual holding-down foot. In front of the pile and having its under side level with the top sheet is a rubbercovered roller or series of discs 4 on a shaft 5 rotated to feed on the sheet to the tape roller 6 and roller 16. Under the discs 4 is a roller or discs 7 on a shaft 8 mounted in spring bearings 9 in brackets 10 pivoted at 12 and operated by a cam on the shaft 14 to press the discs or roller 7 against the discs or roller 4 when the sheet or sheets are fed between. The roller 4 is driven, and when only one sheet is present it drives the roller 7 by friction. The roller 7 is retarded by an adjustable brake 11. When more than one sheet is present, the roller 7 does not rotate and the roller 4 feeds forward the top sheet, the others being detained by the roller 7.
