Title: Improvements in or relating to coin-freed apparatus for meters
IPC: G07F15/02
Filed: 1930-06-06
Abstract: 355,403. Prepayment mechanism for meters. SOUTH METROPOLITAN GAS CO., HART, C. A., and COLEMAN, E., 709, Old Kent Road, London. June 6, 1930, No., 17544. [Class 27.] Coin action, mechanical-connection and with delivery proportionate to value of coin.-In a coinfreed apparatus for meters which can be actuated by any one of a plurality of coins of different value, a penny P inserted into a tapering slot 1, Fig. 5, in a manually rotatable drum 2 protrudes from the slot to engage and drive directly a toothed wheel 6, Figs. 3 and 4, on a shaft 5. The penny may be located by a pin 41. A shilling S passes to the bottom of the slot and engages one of a number of radial grooves 21 in the flange 20 of a sleeve 18 rotatably mounted on a spindle 19 in which one end of the drum shaft 3 is supported. The sleeve 18 is geared through wheels 22, 23 to the shaft 5 which is rotated twelve times as much for a shilling as for a penny. The rotation of the drum 2 is limited by a slot 34 therein engaging a pin 32 on a front plate 33. After the drum is rotated the coins drop out through the mouth of the slot 1 to a money-box. The rotation of the shaft 5 is transmitted through gear wheels, one of which is a change-whee], to a parallel screwed shaft 11 on which a disc 13, mounted to slide on guide-rods 14, travels to open the valve. As gas is consumed, a meter shaft 37 rotates the rods 14 and disc 13, which returns to its initial position and closes the valve. A lever 26 provided with a pin 28 to enter between two teeth on the wheel 6 controls the movement of the shaft 5, a pin 29 on the lever being engaged by a cam 30 on the drum 2. A dwell 22 on the cam allows the pin 28 to engage the wheel 6. The lever 26 is also provided with an extension 36, which moves into the path of the disc 13 and engages this shortly before it comes to the end of its permissible travel. Price-changing mechanism.-The change-wheel is a wheel on the end of the shaft 11. This wheel is removably mounted on a squared end of the shaft and is held in position by a blade spring. Indicators.-The disc 13 carries an indicating pointer 40.

Title: Improvements in the crease proofing of cellulosic fabrics
IPC: A41B1/00
Filed: 1964-04-28
Abstract: A shirt is made from a woven web of cellulosic fibres, e.g cotton or viscose rayon, in such a manner that the main body and sleeves are constructed from the major portion of the web which has been treated with more of a chemical crease-proofing agent than the remainder of the web which is a strip or strips along the edge or edges of the web bordering the major portion, and the collar and cuffs are constructed from the remainder of the web treated with less of the crease-proofing agent so that they are more resistant to wear than the body and sleeves.  A disc plough has a number of discs 7 each mounted on a stump jump arm 24 pivoted at 25 on plates 21 carried by frame members 22, 23, and pivoted at its upper end between a pair of articulated link members 30, the other end of the links being pivoted on the plate p  21 and the hinge 33 of the links being pivotally connected to a spring rod 34 surrounded by a compression spring 36 anchored at 38 to the frame.  The pivotal connections 25, 33, 38 are such that the arm assembly can be removed from the frame as a unit. The frame 5 has at one end a wheel 9 and is supported at the other end on a bar 11 having wheels 12, 13, the wheels being mounted for rotation about a vertical axis, and arranged so that they are all at the same inclination.  The wheels 9, 13 are connected by a link mechanism and a hydraulic ram 14 is connected to the wheel 12 for raising or lowering the discs.ALSO:A web of textile material formed by a continuous inter-weaving from side to side of homogeneously constituted cellulosic fibres, e.g. cotton or viscose rayon, is treated with a chemical crease-proofing agent in such a manner that more of the crease-proofing agent is applied to a major portion of the web than is applied to the remainder of the web which is a strip or strips along the edge or edges of the web bordering the major portion of the web, to render the minor portion more wear-resistant than the major portion.  The lower concentration of crease-proofing agent in the minor portion may be obtained either by using heavier pressing out of the crease-proofing agent from this portion or by using more dilute chemicals for this portion. When used to make garments, e.g. shirts, the main body of the garment is made from the crease-resistant major portions of the fabric so that it is crease-resistant and the parts which are susceptible to wear, e.g. the collar and cuffs, are made from the minor portion of the fabric having less crease-proofing agent so that they are more wear-resistant.

Filed: 1920-06-29
Abstract: 145,575. Stromberg Motor Devices Co., (Assignees of Mock, F. C.). Aug. 23, 1915, [Convention date]. Spray carburettors.-A carburettor has a U- shaped or like fuel well 30, 31 from which fuel is supplied temporarily to a nozzle 36 adjacent to the main nozzle 23 when the throttle valve 29 is fully opened. The arm 31 of the well is in communication through a restricted orifice 33 with the passage 25 from the float chamber 24 to the main nozzle, and has apertures 34, 35 at the upper end leading to the mixture passage 28 and to the atmosphere. These apertures are so proportioned that part of the suction in the passage 28 is transmitted to the arm 31, while the arm 30 is open at 37 to the atmosphere. At starting, the throttle is nearly closed, fuel is drawn from the main nozzle 25 or a by-pass, and the suction through the aperture 34 lifts the fuel in the arm 31. When the opening of the throttle relieves the suction, the fuel drops in the arm 31 and rises in the arm 30, supplying the nozzle 36 until the fuel above the nozzle is exhausted. If the throttle is now partially closed, the level drops in the arm30a.nd rises in 31, but fuel then enters through the orifice 33 until the levels are as shown in Fig. 6. The primary air supply enters a valved inlet 12 and the secondary supply is controlled by a suctionactuated valve 15 connected to a dashpot piston 16 in a fuel chamber 18 connected to the float chamber. The hollow valve stem 17 has a seat 21 co-acting with a fixed valve 20 to admit fuel to a nozzle 19 when the valve 15 opens.

Abstract: 637,253. Catches. CASE, P. F., and NYMAN, P. July 10, 1947, No. 18213. [Class 44] [Also in Group XVII] In a delivery container built into the wall of a house and having compartments accessible from both outside and inside the house, the outside door of each compartment is automatically locked when shut after making a delivery. Each compartment has a hinged tray E which is adapted to be depressed against the action of a spring J by the weight of articles placed thereon. A frame K pivotally mounted beneath the tray carries at one end a claw M lifted by the tilting movement of the tray into a position where it is engageable with a catch C carried on the outer door. A spring-loaded trigger D combined with the claw is displaced by the catch C in the closing movement. When the article is removed from the inside, the tray rises and the claw is thereby lowered out of engagement with the catch and the trigger is returned by the spring P to a position abutting the catch face of the claw. The outer door is now unlocked and remains unlocked when empty bottles &c. are replaced on the tray as the trigger prevents re-engagement between the claw and the catch as shown in Fig. 4. Spring ball catches N on the container engage grooved members O on the outer doors yieldingly to retain them shut when unlocked. All compartments are accessible through a single inside door.
