Filed: 1926-04-26
Abstract: 266,935. Marks, E. C. R., (Bates Valve Bag Co.). April 26, 1926. Packing and filling materials into paper and like bags.-Relates to a method of and apparatus for packing and filling materials into paper and like bags. The free end of an elongated tube of paper &c. is closed, and a charge is inserted through an opening in the side of the tube, which is then closed and severed so as to form a separate bag. As shown, a tube a of paper, Figs. 1 and 3, is fed from a source of supply through a cage 25 and over a spreading device comprising plates 38, Fig. 4. Rollers 35, 37 rest upon the inside of the tube and are supported on the outside by rollers 27. A rod 32, depending from the frame in which the rollers are mounted, carries a tubular member 31 around which the tube is fed downwardly until the lower end is level with a table 48. A flap 42 is resiliently mounted at the top of the tubular member and is adapted to be swung inwardly. In use, a tube of paper is drawn downwards until the lower end is level with a sewing apparatus 52<1>, Fig. 3, and is closed by moving the tube laterally so that a transverse seam 52 is sewn. The tube may then be raised to allow projections at the lower end of the tubular member to press the corners out and open the end of the partially formed bag. The tube is pulled down again until a mark 50 is felt to be level with a bead 47, Fig. 4, on the tubular member. The tube is then swung so that a knife 45 at the bottom of the filling hopper 44 shears transversely through the tube wall and presses back the flap 42 so that the discharge spout registers with the opening in the tube as shown in Fig. 5. A predetermined charge is released and falls to the closed end of the tube, the lower end of which is placed on a conveyer 49. The tube is fed through the sewing apparatus which sews two parallel seams 52 against a reinforceing tape and severs the material between the seams at the point where the material was cut to form the opening for the insertion of the charge. Before the seams are sewn, the tube is bent so as to wrinkle at 53, Fig. 3, to permit the formation of a bellows fold in the bag. The various parts of the apparatus are vertically adjustable.

Abstract: 821,694. Thermally-actuated valves. BRITISH THERMOSTAT CO. Ltd. April 2, 1957 [April 11, 1956], No. 11042/56. Class 135. In a fuel burner safety shut-off valve, the valve obturating member 1 is urged into the shut-off position preventing flow through an outlet 6, by a spring 7 acting on a spindle 2 which has a shoulder 13 engaged by a sliding latch plate 11 to hold the valve in the open position, a pair of thermally-responsive motor devices or bellows 14 and 15 being adapted to operate independently on the latch plate to release the valve in response to flame failure and overheating conditions respectively. The valve may also be adapted for independent actuation into the shut-off position in response to excess flow of the fuel. As shown, the valve is opened by a push-button 8. Lighting of the burner causes thermal compression of bellows 14 against a spring 19, allowing a spring 20 to move the latch-plate to the left into latching position when the button may be released. On flame failure, the latch-plate is returned to the unlatched position by spring 19, or is independently returned by expansion of bellows 15 on overheating, the latch plate having a lost motion connection 18 with the bellows 14 to permit the independent action of the respective bellows. The obturating member 1 is free on its spindle and is of a relatively light material such as nylon, being thereby adopted to close automatically and independently in response to excess flow.
