Title: Improvements relating to the Platens of Typewriting and other Machines
Inventor: CLARK WILLIAM
Filed: 1904-02-09
Granted: 1904-03-31
Abstract: 3219. Clark, W., [Underwood Typewriter Co.]. Feb. 9. Type-writers and l i k e machines.- The spacing-mechanism is arranged so that the platen may stop only at predetermined points corresponding to the intervals between lines, or the platen may be released so that it may be stopped at any point. A brake lever G and a locking-lever H both work on a pivot F adjacent to the usual feeding ratchet-wheel B<2> on the end of the platen shaft B. The two levers are pressed against the wheel by the ends I<1>, I<2> of a spring I coiled round the pivot F. The ends I<1>, I<2> project beyond the levers, and are adapted to be engaged by a controlling-lever J operated by a handle J<2>. When the lever J is in the position shown, the pressure of the end I<1> is taken off the brake lever G, and the end I<2> forces a roller H<1> on the lever H into engagement with the spaces between the ratchet teeth, so that the platen only stops at definite intervals. When the handle J<2> is depressed, the part J<5> of the lever J engages the end I<2> and takes the pressure off the locking-lever, while allowing the end I<1> to act on the brake lever. The platen may thus be turned into any position where it is held by the pressure of the brake lever on the ratchet-wheel. The ends I<1>, I' serve to hold the lever J in one or other of its extreme positions.

Title: An Improved Drip-feed Lubricator.
Inventor: BRADLEY HENRY WENTWORTH
Filed: 1904-05-03
Granted: 1905-03-30
Abstract: 10,190. Bradley, H. W., Bickerton, H. H., and Clerk, D. May 3. Lubricators. -In a drip-feed lubricator, for bearings, cylinders, &c., the flow of lubricant is regulated by means of a spindle a terminating at the lower end in a long taper cone which enters the feed-passage b. The opening between the cone and the mouth of the passage thus depends upon the height of the spindle, which is regulated by means of the adjustable screw-collar or bushing h, upon which a pin g, passing through the spindle, rests. On the spindle is also an enlargement c, adapted to work as a piston in a cylinder lying coaxially with the feed passage b. Holes j admit the lubricant from the cup, and an opening m, which may be protected by glass, in the upper part k of the nipple n allows the rate of flow of oil to be observed. To clean the passages and openings, the spindle is rotated by the handle f until the lugs g may pass through slots in the covering-collar h, when the spindle is reciprocated, the piston c causing a rush of oil to remove any dirt or sticky matter from the openings j, while the spindle itself clears the passage b carrying obstructions into the chamber k, whence they may be removed by an inserted finger. When the lubricator is not required, the spindle a is dropped to its lowest position when the piston c shuts off the feed.

Title: Improvements in and connected with Automatic Emergency Cut-off Valves
Inventor: SEYBOTH FRIEDRICH WILHELM
Filed: 1906-09-05
Granted: 1907-01-10
Abstract: 19,797. Seyboth, F. W., and Baumann, E. K. A., [trading as Konstruktionsb³ro Zwickau Seyboth, Baumann, und Co.]. Sept. 5. Valves closing with rush of fluid; lift valves shocks, preventing.-The valve of an automatic emergency cut-off device for steam-pipes or water conduits is arranged perpendicularly to the axis of the pipe, and the valve is actuated by a differential cylinder which is guided by a fixed piston. The valve may be closed by hand by connecting the cylinder to the atmosphere and thereby relieving part of the valve of its pressure. The valve consists of a cylinder which is free to slide on a fixed piston 8, and normally the fluid pressure on the valve is balanced since the fluid on the underside of the valve is connected to a chamber 9 between the cylinder and piston, and to the upper face 15 of the valve, by passages in a hand-operated cock 13. The weight of the valve thus keeps it open, and steam passes through the valve in the direction of the dotted arrows, or water in the direction of the full arrows. In case of a breakage, the pressure on the face 15 is reduced, and the valve is closed by pressure due to increased flux of steam or backflow of water, the water in the chamber 9 serving as a cushion and preventing sudden closing of the valve. The valve may be closed by hand by connecting the chamber 9 through the cock 13 to the atmosphere, the upward pressure on the valve then exceeding the downward pressure.
