Title: Fishing reel
Inventor: SHAKESPEARE HENRY GEORGE
IPC: A01K89/01
Filed: 1952-01-02
Abstract: 696,868. Fishing reels. SHAKESPEARE CO. Jan. 2, 1952, No. 137/52. Class 48. A fishing reel has a spool 27 associated with a rotatable line-winding member 8 and mounted on a spindle 12 rotatably and reciprocatingly housed in a casing 1, the winding member 8 having a gear 20 driven by a manually operable driving gear 5 and means 36, 39, 43 being provided for axially reciprocating the spindle 12 on rotation of the driving gear 5 in'the line-winding direction W and for actuating and holding the spool 27 in projected position, Fig. 3, for casting, when the driving gear 5 is urged in the opposite direction. As shown the spool 27 comprises two flange members 28, 30 having outwardly bent edges 29, 31 respectively, the edge 29 having a brush face 33 which bears against the inner surface of a cylindrical line winding member 8 to prevent entry of the line therebetween. The spool is fixed on one end of the spindle 12, and the member 8 is secured coaxially to a bevel gear 20 rotatable on the spindle, the other end of the spindle being slidably keyed in a sleeve 15 having a flange 16 rotatable between adjustable friction members 17, 18 in a bearing 7 of the casing 1. The driving gear 5, which is operated by a handle 4, has a wearplate 41 housed in a recess 42 in its inner face, and a curved slot 43 in the plate 41 serves to guide one end of a driving pin 39, the other end of which is engaged with a scotch yoke 36 on the spindle 12. The slot 43 is positioned with one end 45 radially outwardly of its other end 44 so that rotation of the gear 5 in line-winding direction causes reciprocation of the spindle 12, and actuation of the gear 5 in the opposite direction brings end 45 of the slot 43 into engagement with the pin 39 to effect projection of the spool to the casting position. The spool is held in this position since complete rotation of the gear 5 in the said opposite direction is prevented by a stop 121 on the spindle engaging the inner face of the gear 20. Line-winding is effected by a reversible finger member 34 screwed to the periphery of the member 8, the brush face 33 on the spool flange 28 being arranged to prevent snagging of the line with finger 34 during casting.

Title: High pressure fluid intensifier and method
IPC: F03C1/10
Filed: 1974-01-04
Abstract: 1420424 Reciprocating pumps FLOW RESEARCH Inc 4 Jan 1974 [12 Jan 1973 26 Dec 1973] 00443/74 Heading F1A A hydraulically-actuated high pressure pump e.g. for supplying water to a nozzle 22 for cutting drilling or cleaning, comprises a double-acting motor piston 42 connected to pump pistons 44, 46 and reciprocating in chambers 48, 50 connected alternately to a working liquid supply pump 14 and a drain 107 by a hydraulically-actuated spool valve 38 which, in an intermediate position while reversing, connects the supply pump 14 output through a throttled passage means 114 to a low pressure zone, so that the back pressure during reversal is the same as that during the working strokes, thereby alleviating pressure shocks in the apparatus. The throttled passage means is constituted by tapered or stepped edges on the spool valve lands, Figs. 7, 10 and 14 (not shown). The valve spool is biased into its central position by springs 80, 82, and is moved into its left and right hand operative positions by working pressure under the control of pilot valves 85, 86, spool valve-actuating chambers 104, 105 being connected to supply pump 14 via throttles 110, 112 and to pilot valves 85, 86, which act to connect chambers 104, 105 to drain. In operation, in the position shown, pilot valve 86 is held open to vent spool valve chamber 105 by the pressure in working chamber 50, and pilot valve 85 is held closed by its spring 96 until engaged by piston 42, whereupon valve 85 is opened, venting spool valve chamber 104, so that the spool valve is moved into its intermediate position by its spring-loading. Working chamber 50 then de-pressurizes, permitting valve 86 to close and spool valve chamber 105 to pressurize thereby moving the spool valve to the right for the return stroke. If the pump output line 20 fails, the working chamber pressure falls and the associated pilot valve closes, causing the spool valve to move to its intermediate position and stopping of the pump. In normal use, when the pump is stopped, the spool valve moves to its intermediate position, and operation of a starting valve 120 to vent one of the spool valve chambers 104 or 105 is necessary to start the pump. In Figs. 12 to 14 (not shown), a pilot valve controlling the reversing of the spool valve is controlled with a quick-throw action by cables with plungers engaged by the working piston at the end of each stroke, the spool valve having an intermediate position in which, in addition to connecting the pump 14 through throttled passage means to a low pressure zone, the working chamber 48 or 50 under pressure is connected through a throttled passage to drain to alleviate pressure shocks.

Title: A single trigger mechanism for a sporting gun
IPC: F41A19/20
Filed: 1932-01-07
Abstract: 381,421. Single-trigger and like mechanisms for sporting guns. BROWNING, V. A., 1, Rue des Rivageois, Liege, Belgium. Jan. 7, 1932, No. 542. Convention date, Jan. 7, 1931. [Class 119.] Relates to single-trigger and like mechanisms for double-barrelled sporting guns of the kind in which a connecting member between the trigger and sears is automatically displaced from one sear to the other after the first shot has been fired. According to the invention, the displacement is effected by the return to its initial position of a movable mass which is displaced, in the first instance, by the effect of the recoil. In the form shown, a sporting gun is provided with two triggers 2, 2a, Fig. 5, which are normally connected to the sears 4, 4a, respectively, by connecting members or separators 5, 5a, Fig. 2. Each separator is formed with a beak 7 engaging beneath the corresponding sear and with a lateral stop 12 with which a two-part, spring-actuated, pivoted lever 13 is adapted to co-operate. Engagement of the lever 13 with the stop 12 of a separator is normally prevented by the combined action of the tumbler 10 or 10a and a forward extension of a movable mass 18, which members tend to retain the lever in its lowermost position. Upon pulling the trigger 2, the separator 5 and hence the sear 4 are raised and the tumbler 10 is released to fire the shot, and the mass 18 recoils against the action of its spring 20 when the shot is fired. These movements of the tumbler and mass 18 release the lever 13 and the latter is raised slightly by its spring 16 to a position in which a part 17 thereon is brought into the path of the mass 18. Thus, when the mass returns to its initial position, the lever is raised by it and the free end of the lever rides up an inclined surface on the stop 12 of the separator 5 and thereby presses the latter towards the separator 5a against the action of a spring 22. The beaks 7 of both separators are now disposed beneath the sear 4a so that the tumbler 10a is released upon the application of pressure to either of the triggers 2, 2a. The action is similar if the trigger 2a is pressed first, except that the first shot will be fired by the tumbler 10a. As applied to a single trigger doublebarrel gun, only one separator is provided, the spring 22 in this case being arranged between the separator and the fixed casing of the gun.

Title: Improvements in relays for indicating or control apparatus
IPC: G05B1/04
Filed: 1932-01-11
Abstract: 395,393. Resistance measurements; potentiometers. FOSTER, C. E., Elm Tree House, Letchworth Lane, Letchworth, Hertfordshire. Jan. 11, 1932, No. 776. [Class 37.] Recording, indicating, or control apparatus having a galvanometer provided with a mechanically depressed pointer operating periodically a brake or similar release mechanism has this release mechanism where engaged by the pointer so shaped as to cause the operation of the release to follow a predetermined time cycle which may be so proportioned that the restoring effect will be proportional to the out-of-balance condition. The invention is shown applied to an automatically balanced wheatstone bridge or potentiometer as described in Specification 8205/07, [Class 37, Electricity, Measuring &c.], in which an arm A is carried by the shaft Y of the moving coil G of a galvanometer under the influence of the out-of-balance current. The arm A is pivoted horizontally so that it can be periodically depressed by a presser bar P which moves it downwards to a position below a pair of oppositely-disposed brake levers B1, B2 engaging wheels W1, W2 operated by a clockwork or other motor. These wheels are driven in opposite directions and drive through differential gearing a drum S1 over which passes a cable R operating the carriage W which carries the contact C, moving over the slide wire E, and a recording pointer Q moving over a chart Z. When the potentiometer is balanced, depression of the bar P causes the arm A to release both brakes B1, B2 slightly but equally so that no motion of the carriage W ensues. When the potentiometer is out of balance, one brake is released for a longer time than the other, causing the carriage W to move in the direction to effect balance. In order that the restoring effect shall be proportional to the amount of out of balance in spite of the speeding- up of the wheels W1, W2 when released, the cam that depresses the bar P is so shaped that there is a dwell at the bottom of the depression and the bent-down portions b of the brake arms are so shaped that the brakes are released for a proportionately longer time near the position of balance.
