Title: Improvements in and relating to Means for Automatically Stopping Looms or Changing Shuttles in Looms.
Inventor: ROEHRIG FRIEDRICH WILHELM
Filed: 1899-09-21
Granted: 1899-12-16
Abstract: 18,985. R÷hrig, F. W. Sept. 21. Loom shuttle-changing mechanism; stop-motions; swells.-When the weft on the bobbin has become nearly exhausted, the loom is stopped automatically, or a fresh shuttle is inserted in position in the rotary shuttle box 30. The loom is also stopped automatically when the shuttle fails to enter the shuttle box. For changing the shuttle, the disc 15, Fig. 2, is first set in such a position that, after a certain length of weft has been used, a projection 16<c> on a lever 16 falls into a notch 15<a>, and by means of a link 18 the lever 16 shifts the hook 19 into engagement with a cam-actuated lever 10 described in Specification No. 12,224, A.D. 1898. This causes the lever 20 to be rocked, and the shuttle box 30 to be turned one step, bringing a fresh shuttle into operation from a hopper or receptacle. At the same time the rod 25 lifts the pawls 4, 11 out of gear with their ratchet-wheel 12, and allows a weight 24 to return the disc 15 to its starting position. Instead of this the lever 16 may be connected to the stopping-gear of the loom. For stopping the loom in case the shuttle fails to enter the shuttle box, each cell is provided with a spring swell 31, Fig. 3, which is pressed into its recess at the extreme positions of the lay by means of fixed cam-pieces 34, 35. When the shuttle is in the box, it operates upon the finger 36 on the rod 38, and lifts the arm 37 into the position shown in dotted lines, but, when the shuttle fails to enter the box, the arm 37 is allowed to engage with the sliding-block 39<a> which operates the stopping-gear of the loom. In a modification, the cam-pieces 34, 35 are dispensed with, and the ends of the swell are covered by a plate, and a spring is placed between them, at the inner end of the swell, to act against the stronger spring 37<a> of the arm 37.

Title: Improvements in and relating to Steam Engines.
Inventor: WHITFIELD MARCY LELLAND
Filed: 1900-03-06
Granted: 1900-06-30
Abstract: 4257. Whitfield, M. L. March 6. Engines with reciprocating cylinders; cycles or systems of working; valves and valve gear.-Relates to engines of the type in which a reciprocating piston-cylinder works within a stationary cylinder and over a stationary piston-abutment, and consists of means for enabling such engines to be worked either compound or simple, and to be reversed. The invention is especially suitable for marine engines and locomotives; it is illustrated in the Specification as applied to vertical engines and to horizontal engines. Fig. 2 shows a vertical section of one form, and Fig. 3 shows a part section at right-angles to that shown in Fig. 2. In these c is the stationary cylinder, d, e the reciprocating piston-cylinder provided with a crosshead 6 to which the connecting-rod 7 is attached, and g the stationary piston supported by the abutment f, which is bifurcated so as to clear the crosshead and connecting- rod. The main distributing- valve l works in a casing k supplied with live steam by the branch 42 and communicating with the interior of the reciprocating cylinder by passages 3 in the bifurcated abutment f. There is an oscillating exhaust valve h lodged in a casing forming the upper cylinder cover, and an intermediate valve i lodged in the piston e and made to oscillate with the valve h by means of the splined spindle 13. The main valve l is worked through arms m on a rocking shaft by a double-eccentric link - motion, and from the main valve the movement is transmitted to the exhaust valve through suitable linkage and thence to the intermediate valve. The main valve l is in the form of a sleeve closed at the ends by piston heads. It has three sets of ports, one much larger than the others, working over three sets of ports in the valve-chest liner, and its action depends upon the extent of its travel. With limited travel the working is compound ; steam is admitted to the piston-cylinder to effect the up-stroke, the exhaust valve h being open, and at the completion of the stroke the exhaust valve is closed and the intermediate valve i is opened, thereby allowing the steam to expand from one cylinder into the other during the downstroke, on the completion of which the same action is repeated. With increasing travel the cut-off becomes later, and at a certain point steam begins to be admitted to the large cylinder during the down-stroke ; with full travel of the valve simple working is established. The link-motion enables all these changes to be effected by an ordinary reversing-lever, and also enables the engine to be easily reversed.

Title: Improvements in Electric Brakes for Electric Railway Vehicles.
Inventor: NEWELL FRANK CLARENCE
Filed: 1900-05-16
Granted: 1901-04-13
Abstract: 9058. Newell, F. C. May 16. Electric locomotives and motor vehicles.-A single braking-switch 42, operated from either end of the vehicle, cuts off the main current supply from the trolley 84, and couples up the motors 98, 102, which then run as generators on a circuit including the magnetic-brake device 108, the driver's running controllers 40, and reversing- switches 41 irrespective of their position at the time. The controllers 40 in connection with the ordinary resistances 93 can then be used to control the action of the brake when its switch is in the on position, shown in Fig. 2, and, when it is in the off position, as shown in Fig. 1, the ordinary series-parallel control is obtained. The brake switch is held off by the spring 9, and is pulled on by the slotted rods 5 and levers 2, which can be held by the pawls 10, the action at the ends of the vehicle being independent.

Title: Improvements in Apparatus for Mixing and Burning Inflammable Gas and Hydro Carbon Vapours and Air for the Production of Light and Heat.
Inventor: BOWER GEORGE
Filed: 1900-06-07
Granted: 1901-06-07
Abstract: 10,432. Bower, G. June 7. Gas stoves.-Relates to a lamp or heating - appliance in which the supply of gas or hydrocarbon vapour, the supply of air, and the amount of surface of a mantle exposed to the flame are all regulated simultaneously by one movement. In the form shown applied to a lighting-burner in Fig. 2, the burner has a tube 1 upon which can slide a sleeve 10 carrying, by means of the rod 8, the mantle. Upon the sleeve is a projection 11, which bears against a cam surface 13 mounted on the gas tap 14 and provided with a handle 15. By turning the gas tap on, that is, in the direction of the arrow, the sleeve and, therefore, the mantle are raised, and the air inlet perforations 9 are uncovered to a greater or less extent. The burner tube is formed, as shown in Fig. 1, with an outer tube 1 having a tubular porcelain or other lining 3, above which is a compressible washer 5 upon which another similar lining 4, shaped as shown, rests. The top is covered with a cap having a wire-gauze or perforated disc 6, which, in the case shown, carries the mantle rod 8. Beneath are air-supply holes 9 and the gas jet 2. Several devices for simultaneously performing the movements abovementioned are described. In one, the gas valve is a screw and carries a pinion which gears with a rack attached to the sliding sleeve. In another form, the mantle and sleeve are fixed, the upper part of the tube being connected with the burner tap so as to fall when the gas is turned on, and vice versÔ. In another example, the sliding sleeve is internal, and is provided with an external ring and pins passing through spiral slots in the outer casing, these slots also serving as air inlets. As the ring is screwed down, the sleeve also falls, more of the air openings are closed by the sleeve, and finally the pointed lower end of the mautle rod falls into the gas-supply jet orifice, and so cuts off the supply of gas. Or, again, the slot may be vertical, with the pins simply moving up and down in it. In another form, by turning a screw a pointed rod is passed up the gas jet to close the orifice, at the same time that the sleeve and mantle are lowered at a quicker rate, the difference in rate being due to the use of screws of different pitches simultaneously operated. The mantle may be carried so as to prevent shock by vibration. By omitting the mantle, the burner may be used for heating vessels.

Filed: 1900-09-08
Granted: 1901-09-07
Abstract: 16,019. Grimshaw, R. Sept. 8. Door-closing apparatus; hinges.-To the bottom of a door M<1> is attached a shoe M, to which is secured a spindle C carrying a plate D and overlapping leather washers F, F<1> arranged to form a piston working in a cylinder B. Attached to or formed integral with the spindle is a bracket H<1>, in which is mounted a pulley K, which travels in a semicircular inclined or tapered groove P. When the door is closed, the pulley rests in a step in the groove. Upon opening the door, the spindle C is raised, thereby raising the piston and forcing the air from above the piston through a valve Q, or past the piston leathers, to the space at the bottom of the cylinder. The door closes by its own weight, and the air below the piston is compressed and allowed to escape through passages R, X, thereby cushioning the door in closing. The escape of the air is regulated by a valve S<1> adjusted by a screw R'. Air is admitted to the space above the piston by a passage or along the sides of the spindle. A spring E serves to cushion the piston in rising. In a modification, the bracket H<1> is cast integral with the shoe.
