Title: Improvements in Vacuum Drying Apparatus for Continuous Working
Inventor: HILLIG OTTO MORITZ
Filed: 1901-08-29
Granted: 1902-04-10
Abstract: 17,364. Hillig, O. M., and M³ller, W. Aug. 29. Drying-apparatus.-A continuous vacuum drying-apparatus is shown in Fig. 1. The circular chamber is divided in radial drying-compartments a with perforated partitions or floors b. The partitions are connected by passages d, Figs. 1 and 6, with a rotary valve f, which has radial ports h connecting apertures e in the passages d with the central vacuum chamber g. A rubber disc valve l is normally pressed upwards by a coiled spring, and, when pushed down on to its seat by the pressure in the vacuum chamber, closes the ports in the valve f. In operation, when a compartment is to be recharged, the valve f is turned to shut off the vacuum chamber. The compartment is emptied and recharged, and by means of a passage k in the valve it is connected to the vacuum chamber, and thus produces a rise of pressure which causes the disc valve to close and the recharged chamber only to be exhausted, until equilibrium is established, when the disc valve rises and all the chambers are brought into action. In a modification, the valve f<1>, Fig. 11, has two sets of radial ports h<1>, h<2>, controlled by two rubber valves l<1>, and connecting by two sets of passages e', e<2> with an upper and lower series of drying-compartments, respectively. By means of a port m in the valve f <1> and corresponding ports o' in the valve casing, two adjacent compartments can be put into communication so as to equalize the pressure in a recharged chamber and in the adjoining chamber, which is about to be discharged. The modified valve may be adapted to the first-described form of the invention.

Patent GB-190216208-A (GB)
Title: Quick-acting Distribution Apparatus for Vacuum-brake-cylinders for Railway and Tramway Vehicles
Inventor: MILLING JACOB CHRISTIAN
Filed: 1902-07-21
Granted: 1903-07-09
Abstract: 16,208. Milling, J. C. July 21. Brakes.-The vacuum brakes of a train of railway or tramway vehicles are applied and withdrawn slowly or rapidly by causing the air to flow to and from the brake cylinders through the apparatus shown in Fig. 1. The apparatus is so attached to the brake cylinder, that the passage 1 communicates with its upper part, and the passage 4 with the vacuum chamber or reservoir. To apply the brakes lightly, the air is admitted slowly to the vacuum pipe 24 and to the chamber B, and lifts the plate 9 covering the apertures in a piston or diaphragm 10. The air then passes through the passage 2 to the lower part of the brake cylinder. If the air is admitted rapidly, the apertures in the piston 10 are closed by a ring 13, which is connected to the plate 9 by distance-pieces 12 working in the apertures. The apertures being closed, the piston 10 is lifted, and carries with it the cylindrical valve 18, so that the external air is drawn through the filter 22 and through the valve 18, and passes into the brake cylinder, and the brakes are applied rapidly. When the brake cylinder is filled with air, and the pressures on both sides of the piston have become equal, the valve 18 and the piston 10 are drawn down by the spring 19, and the plates 9 will fall so as to close the apertures in the piston 10. If the air is pumped slowly from the pipe 24 and the lower part of the brake cylinder, it passes through small perforations 25 in the piston 10, which is not moved by the flow of air. If the pumps act rapidly, the pressure in the chamber B falls below that in the chamber A, the piston 10 is forced down, and the spring valve 5 is drawn down with it. The chambers 1, 2 are thus thrown into communication, and the pressure on both sides of the brake piston is equalized, so that the brakes are removed immediately. If the suction is strong enough, the piston 10 is drawn down until the ring 13 strikes the top 14, and the plates 9 are lifted from the piston, thus enlarging the area of the flow. When the pressure is equalized, the piston 10 is lifted by a spring 15. The mouth of the chamber C is arranged for the attachment of a hose in dusty or snowy weather. A spring-loaded lift valve on the passage 4 serves to admit air to the brake cylinder when the brakes are to be released on uncoupling the engine.

Title: Improvements in Boring Machines
Inventor: HARKER WILLIAM
Filed: 1902-10-14
Granted: 1903-08-20
Abstract: 22,339. Harker, W., and Allcock, A. T. Oct. 14. Deep-boring. - Relates to the class of boring- machines, such as diamond boring-machines, in which the feed is determined by the difference of speed of a nut and the screw to which the boring-bar is connected. As shown in Fig.1, the screw A drives the countershaft B by spur gearing 1, 2, and on the shaft are mounted the fast and loose bevelwheels C, D, between which are two or more bevel-wheels G mounted inside the spur-wheel E which drives the feed-nut H. When the bevelwheel D runs free, no motion is given to the nut H, but when it is fixed, the nut and screw A run at the same speed. For intermediate speeds, the bevel-wheel D is driven by means of its attached ratchet-wheel J, to which motion is imparted by a pawl 17 on the radius-arms 16 oscillated from an adjustable crank M on the rocking shaft L, which is worked by a cam 9 on the driving-sleeve of the screw A. The ratchet-wheel J may be held stationary by a second pawl 6, operated by a handle 21, which also serves to turn a plate N to mask the ratchet wheel from the pawl 17, and to put a brake 22 on the spur-wheel E. Worm gearing may be substituted for the ratchet gearing, and driven from the main shaft through speed cones and belting. Another modification is shown in Fig. 8, in which the epicyclic bevel gear is concentric with the feedscrew, the bevel-wheel D being fixed to the nut I and the spur-wheel E being driven from a countershaft, which is run at any desired speed by ratchet or worm gear, as described above.
