Title: An Improved Automatic Mercury Vacuum Pump.
Inventor: MILNER SAMUEL ROSLINGTON
Filed: 1903-01-08
Granted: 1903-03-19
Abstract: 493. Milner, S. R. Jan. 8. Exhausting.-A T÷pler pump is converted into an automatic portable apparatus as follows:-A three-way cock T, communicating with the reservoir A at u, the atmosphere at z, and the water pump at v, is actuated automatically by solenoids K, K<1>, the circuits of which are controlled by mercury contacts X, X', Z in the air-escape pipe, and U, V in the reservoir A. The circuits are broken after each movement of the cock by a lever i and contacts j, j<1>, so that no sparking occurs at the mercury contacts. The process of working is as follows :-After the system has been exhausted by the water pump, the cock M is closed, and the vessel A is put into communication alternately with the atmosphere and the water pump by the cock T. The cock is first reversed by the contact Z, the circuit through X, X<1> being broken by a circuit through Y, Y', in a manometer G, acting on the contact Q. After a time, however, the air pressure in E fails to force the mercury so high as Y, Y' for several strokes, when the contacts X, X<1> control the valve. When, however, the pressure does rise high enough to make contact at Y, Y<1>, then the contacts X, X<1> are cut out until the mercury is forced to Z. The valve M is constructed with a mercury seal, as shown, and is inclined at an angle of 45‹ so that, when it is turned off, its opening to the pipe n<1> comes below the mercury.

Title: Improvements in Steam Generators.
Inventor: FROMONT FERNAND ADRIEN
Filed: 1904-12-05
Granted: 1905-06-29
Abstract: 26,491. Fromont, F. A. Dec. 5. Sectional boilers; partitions, internal.-A generator consists of an upper steam and water drum 1, and one or more heating- tubes 3, which are each formed from two tubes eccentrically arranged one within the other and enclosing an annular water space, the widest part of which is at the top. The form described, of which Fig. 1 shows a vertical section with the lower part of the plane of section displaced, has four of these heating-tubes, which are connected by branch tubes 2 to each other and to the drum 1. The upper branch tubes are surrounded by outer tubes 9, which extend a short distance above the water line. The front ends of the tubes 3 are connected by curved sections 4 of similar eccentric construction. To facilitate the discharge of the bubbles of steam, thin perforated plates are arranged in the annular water spaces, the branch connecting pipes 2, and the tubes 9. These plates are of horse-shoe shape, and are formed in two parts connected by a hinge at the bottom and a strap at the top. The furnace gases surround the outer surface of the heating-tubes, and pass behind a partition 19 and through the lower tubes 3, and subsequently through the upper tubes and past the feedwater heater. Steam receivers; priming, preventing.-The steam receiver is fitted with a number of perforated conical partitions 8 for the prevention of priming. Feedwater, heating. - The feedwater - heating arrangements are shown on the right of Fig. 1 and in Fig. 3, which is a section on the line C C, Fig. 1.

Title: Automatic Oiling Device and Alarm for Engines.
Inventor: TISMER PAUL GERHARD
Filed: 1905-02-13
Granted: 1905-05-11
Abstract: 2933. Tismer, P. G. April 4, 1904, [date applied for under Patents Act, 1901]. Indicating interruption of flow of liquids.-A multiple-delivery lubricator for steamengines &c. is provided with a whistle or other alarm to give warning of a defect io the lubrication, and d with means for indicating the situation and nature of the defect. The chamber 1 is supplied through the pipe 2 with lubricant under a pressure of, say, twenty pounds per square inch, obtained by means of an elevated tank or otherwise. A number of ducts 4, arranged in a circle, lead to the bearings. Lubricant at a higher pressure of, say, forty pounds per square inch, is supplied, preferably by a rotary pump geared to the engine, through the valve-chamber 27, passage 25, and a pipe 5, which is rotated in stuffing-boxes 6, 11 by means of the wheel 16, engaged by the weighted pawl 17, operated by the reciprocating rod 24. The branch 10 of the pipe 5 has an opening which registers in turn with the ducts 4, and is held in close contact with the wall 3 of the chamber 1 by the screw 43. The opening in the branch 10 is bevelled, so that in intermediate positions between the ducts 4 the oil discharges into the chamber 1. The by-pass 33 connects the chamber 1 with the valve-chamber 27 through the port 34. To reach the pipe 5, the high-pressure oil displaces the floating valve 26, which is suitably weighted by means of the chamber 31 fixed to the stem 32. In the balanced position of the valve 26, the port 34 is closed. The high-pressure oil supplied successively to the ducts 4 serves to remove obstructions, and acts as a test that the lubrication is proceeding properly. Should a leak or break occur in one of the ducts 4, the pressure in the pipe 5, when the branch is opposite that duct, will be reduced, and the valve 26 will fall, closing the opening to the valve chamber 27, and opening the port 34. At the same time, the disk 39 on the valve-stem 32 engages the arm 45b of the strip 45, Fig. 4. This shortens the toggle 48, 49, and causes the point 51 on the arm 49 to make a puncture on the dial 52 opposite a graduation corresponding to the duct which is defective, and the link 56 opens the valve 55 of the steam whistle 54. Similarly, if one of the ducts becomes clogged, the pressure rises, lifting the valve 26, and the disk 39 engages the trip-arm 45<a>, causing the dial to be punctured in a different position, and the whistle to sound as before. The dial 52 is rotated by the gear-wheel 19 fixed to the pipe 5.
