Inventor: BRINKHAUS HUGO
Filed: 1898-01-04
Granted: 1898-02-26
Abstract: 225. Brinkhaus, H. Jan. 4. Rolling of vessels, utilizing for propelling.-The vessels are provided with bilge heels each consisting of a series of plates 9 pivoted to shafts mounted in bearings carried outside the hull. Each plate 9, while oscillating under the action of waves and the motion of the vessel, communicates its motion to toothed sectors 15 mounted loosely on a shaft 16. Ratchet levers 20 convert the oscillating motion of the sectors into a continuous rotation of the shaft 16, which transmits the motion through a spring connection and gearing to a shaft 38 common to all the power plates 9. A disengaging-clutch is fitted on each intermediate shaft 35. The shaft 38 may be the propeller shaft of the vessel, or in an anchored vessel it may transmit its power through a dynamo and electric conductors to any desired destination. The anchor cables may also be made to actuate the shaft 16 during the upward and downward movement of the vessel.

Title: Improvements in Obtaining Gold from Certain of its Ores.
Inventor: SULMAN HENRY LIVINGSTONE
Filed: 1898-05-13
Granted: 1899-03-18
Abstract: 11,001. Sulman, H. L. May 13. Gold.-Relates to a process for obtaining gold from base mineral sulphide ores, especially those containing iron pyrites, marcasite, mispickel, copper pyrites, galena, blende, &c., by heating them with a solution of an alkaline or alkalineearth polysulphide. As an example, a 30 per cent. solution of sodium sulphide, to which from 5 to 150 per cent. of sulphur is added, is maintained at a temperature of 85‹ to 100‹ C., and the crushed ore is then added, the proportion of polysulphide solution being from 40 to 70 per cent. of the weight of the ore. The solution of the gold may take place in the steam-jacketed vessels A, A', which are connected above by a pipe having a valve F, and below by pipes E having a valve e. Near the bottom of each vessel is the perforated iron plate C. The solution may be passed from one vessel to the other so as to act upon several successive charges of ore, or be discharged completely, by admitting steam to the upper part of the vessels. The solution obtained contains a double sulphide of sodium and gold. The gold may be separated by any known means, such as by electrolysis. The latter process is described ; the polysulphide solution being re-formed for re-use.

Title: Improvements in Printing Machines.
Inventor: GILL LEONARD UPCOTT
Filed: 1898-06-13
Granted: 1899-05-13
Abstract: 13,207. Gill, L. U., and Bradley, A. G. June 13. Cylinder machines with plane printing - surfaces; feeding sheets; delivery apparatus. - Relates, firstly, to apparatus for cutting sheets from a web and feeding them to the impression cylinder, and, secondly, to apparatus for delivering the printed sheets. The web E' is fed from a roll E by a pair of drawing-rollers b, b<1>, and passes through a pair of guide-plates a to feed-rollers c, c<1>. A loop of web E<3> is left between the rollers b, b<1> and the guide a. The roller b is covered with rubber or the like, and it is driven by bevel gearing &c. from a cone e driven by a friction-wheel from a second cone e' driven by bevel gearing &c. from a cam shaft g. The friction-wheel is adjustable along the cones by a screw e<3> for varying the speed of the rollers b, b<1>. The roller c is covered with rubber and, the roller c<1> is driven intermittently by gearing from a shaft c<5> operated by ratchet mechanism and a crank on the shaft C. The shaft g is driven by chain gear g<7> from the shaft C, which is geared to the driving-shaft B. The sheet is cut off by a cutter lever F operated by a rod and a crank-pin on the shaft g. The sheet E<4> is carried by reciprocating grippers d down the feed-board G to the grippers H<1> of the cylinder H. I represents the reciprocating bed, J the ink table, K the inking-rollers, and L the distributing-rollers of the machine. The grippers d are reciprocated by arms on a shaft h<4> on which are two arms operated by cams on the shaft g. The rollers c, c<1> feed sufficient web for the shortest sheet, and when a longer sheet is required the grippers d move the required distance, drawing the web with them, and then remain at rest during the cut. This movement is effected by a stepped cam adjustable on the shaft g. The roller c is raised and lowered, and grips the web on to the roller c', which is then at rest, while the cut is made. The sheet passes under smoothers d<3> over the gripper plate d' to the grippers d. The grippers are opened at the required times by a pivoted plate operated by a cam &c. The printed sheets are delivered by the grippers H<1> to sets of tapes k, k<1> which deliver them to sets of tapes l<1>, l<2> mounted in a pivoted frame oscillated to move the tapes alternately into position to receive the sheet from the tapes k, k<1>, and to deliver it to the reciprocating grippers m. The sheet is stopped as it moves up the tapes l<1>, l<2> by fingers o' on an adjustable bar o. The tapes l<1>, l<2> are driven alternately in opposite directions. The grippers m carry the sheet and deposit it, printed side up, in the delivery box N. The grippers m are reciprocated in guides m<2> by lever &c. mechanism, and are opened to receive and release the sheet by projections on the framing. As the grippers approach the lower end of the box N, they operate fingers which free the sheet from the grippers. They also operate a knocker-up which knocks up the sheets against an adjustable side guide n'.

Title: An Improved Stuffing-box or Packing-device.
Inventor: STUMPF JOHANN
Filed: 1899-10-13
Granted: 1899-11-18
Abstract: 20,573. Stumpf, J. Oct. 13. Stuffing-boxes.-Packing and lubrication are jointly effected by the use of a relatively hard grease, such as raw beef suet, which is kept under suitable pressure. The invention is shown as applied to a plunger pump. The plunger c passes through a pair of grooved bushes f, between which is situated the chamber containing the grease. This is subjected to pressure by a piston h. to the upper side of which liquid from the pump delivery is admitted by a tube i. A screwed spindle m not connected to the piston is provided for putting pressure on the grease when the pump is not working. Grooving of the plunger (or piston-rod) is avoided by the use of this device, and the film of grease on the plunger serves to protect it against the action of corrosive liquids.
