Title: Improvements in or relating to Apparatus for Automatically Weighing Grain and Granulated or Powdered Substances.
Inventor: SIMON RICHARD
Filed: 1897-08-25
Granted: 1898-08-20
Abstract: 19,635. Simon, R. Aug. 25. Automatic-feed weighers.-An arrangement of apparatus for weighing grain and the like consists of an equi-armed balance beam A having a weight pan B at one end and a sack-holder D at the other. The escape of granular material from the hopper is controlled by a pair of cut-off gates G, H, which are pulled over by hand and kept in position by a pawl. The descent of the beam under the action of the weight causes the disengagement of the pawl, and the outer gate is nearly closed, leaving a dribbling feed only past the inner gate. As the beam continues to descend, a catch upon the trunk D completely closes the gate and stops the feed. The sack is then removed and another put in its place, the action of the apparatus commencing anew.

Title: Novel or Improved Apparatus for use in Maintaining the Water in a Steam Boiler, or in each of a Number of Steam Boilers, at, or Approximately at, a Constant or Desired Level.
Inventor: EVANS JOSEPH
Filed: 1897-12-24
Granted: 1898-11-19
Abstract: 30,484. Evans, J., and Evans, W., [trading as Evans & Sons, J.], and Hopwood, A. Dec. 24. Feed-pumps for steam generators. In order to maintain the level in a steam boiler, especially in the case of a watert u b e boiler, a return pump is employed which removes excess of water from the boiler and returns it to the tank supplying the feed-pump or injector, or to the suction valve of the feed-pump. Circulation is thus promoted at the sime time. In the arrangement shown, the feed-pump A and return pump B are arranged in line, with a common plunger. The feedwater is supplied to the water drum C of a water-tube boiler, and the excess is withdrawn from the steam drum D by the pipe b, the end of which is T-shaped as shown, or otherwise shielded, to prevent the passage of scum to the pump. The discharge pipe of the return pump communicates both with the feedtank J and with the suction-valve' box L of the feed pump. The two pumps may, however, be variously arranged, and one double-acting pump may serve both purposes, one end being arranged to supply the feed and the other to withdraw the excess. The discharge valve E, Fig. 4, of the return pump is pressed down by steam from the boiler acting on the piston G, or otherwise loaded to prevent it from being raised except by a pressure exceeding that of the boiler ; and the clearance spaces of the pump are so proportioned as to prevent steam which enters the pump, when the water level in the boiler is below the normal, from being compressed sufficiently to lift the valve. In the case of a double-acting pump, a similarly-loaded valve may be inserted in the discharge pipe.

Title: An Improved Means for Producing Acetylene Gas.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1898-04-21
Granted: 1898-11-26
Abstract: 9269. Thompson, W. P., [Grand, J.]. April 21. Acetylene l a m p s; velocipede l a m p s .- Acetylene is produced without water coming into actual contact with the carbide. The carbide is contained in a porous vessel and the water in an outer vessel, and the humid atmosphere inside the carbide container, due to moisture passing through the porous walls, acts upon the carbide to generate the gas. The method is particularly applicable for bicycle and carriage lamps. In the form shown, the carbide is contained within, but does not fill, the porous vessel A, which is supported by a ring E attached to a bell B immersed in the water reservoir C. The exit of gas is regulated by the tap D. In this case, the water is driven away from the sides of the vessel A when the gas accumulates therein. In other forms, in which there is no bell, the water is always in contact with the outer side of the porous vessel. The vessel may be made of porous earthenware or other suitable material, as, for example, of paper pulp mixed with tar and flour strongly compressed and carbonized in a furnace.
