The diaphragm is loaded by a spring 19 disposed in a removable cover 16 having a connection 28 leading to the engine induction manifold. The centrifugal governor is normally controlled by the spring 7 whilst the spring 6 is compressed when the speed tends to increase beyond the full load maximum setting. A cover 15 allows access to the centrifugal governor. A spring-loaded stop 22 connected with an external lever 21 limits the maximum fuel position of the bolt 17. The stop is adjustable by a screw 25. In another embodiment, Fig. 4, the stop 36 is provided on a lever 35 pivoted on a pin 37 mounted on an adjustable crank arm 38. The lever 35 is secured to a pin 34 carried by a diaphragm 30 sealing a chamber 31 connected with the chamber of the pneumatic governor. When the engine is stationary or at starting speed a spring 39 displaces the diaphragm to the left thus removing the stop 36 from the path of a lever 12 and thus allowing excess fuel. As the speed increases the diaphragm 30 moves to the right and engages a stop pin 40 thereby re-setting the stop 36. Instead of the diaphragm 30 an electromagnet may be provided which is energized simultaneously with the electric starter for the engine.

Title: Improvements in drag devices for spinning, doubling, twisting and like machines used in the production of yarns or threads of fibrous substances
IPC: D01H7/44
Filed: 1922-10-03
Abstract: 207,657. Constantine, F. W., and Kay, T. G. Oct. 3, 1922. Spindle apparatus.-In a drag device for spinning and like spindles 2, the viscosity of a liquid which is carried in sleeves 3 is utilised to retard the motion of the said spindles. The sleeves 3 are supported within a horizontal tube 6, which acts as a lifter-rail, and communicate therewith by means of openings s. Mounted upon the tube 6, and connected thereto by a pipe 11, is a vessel 10 which contains the viscous liquid. Coacting with the vessel 10 is a member 12 supported by a stem 12a from an arm 13<a> of a member 13 which is secured by a spring 14<c> against the bar 15. When spinning begins, the spindles 2 and tube 6 will be in their highest positions, and as the tube 6 reciprocates vertieally over a space equal to that from the shoulder h of the cop to its nose f, the member 12 will cause the liquid in the container 10 and in the sleeves 3 to vary in height and thereby to apply a varying drag to the spindles 2. In addition to its reciprocations the tube 6 descends gradually, and at each stage in its descent the base of the vessel 10 makes contact with the portion 13<b> of the member 13 and causes it to slip over the bar 15. In a modification each spindle 2, Fig. 6, is provided with a separate tube 16 taking over the sleeve 3. The sleeves 3 are carried bv the lifter-rail 17 which is actuated by the rod 17<a>, while the tubes 16 are, carried on a rail 18 supported by rods 19, and the levers 17<b>, 20 are arranged to give a double, or other desired multiple, travel of the rail 18 relative to the rail 17 to secure the desired variation of the level of the liquid, and thereby of the drag. Spindle and sleeve dimensions for use with a specified oil are quoted for yarns of one hundred counts.

Abstract: 853,829. Stuffing-box substitutes. CRANE PACKING Ltd. Aug. 21, 1959 [Aug. 22, 1958], No. 27007/58. Class 122 (5). In a rotary shaft seal comprising sealing members 3, 8 urged into contact with one another axially and cooled by passing some of the sealed liquid over them, the surface of at least one of the members in the path of the coolant is extended by fins 13, grooves 14 &c. to increase the cooling effect. The member 3 rotates with the shaft 1 and the member 8 is axially slidable on a ring 7 which is secured to the shaft housing 2, prevented from rotation by; pins 10 and urged by springs (not shown) into facial contact with a carbon-ring 6 on the member 3. Fluid from within the housing 2, which may be a pump housing, is fed at a pressure exceeding that within the housing to the ring 7 whence it flows through passages 11, 12, past the members 3 and 8 which it cools and is returned to the interior of the housing through the clearance between the housing and the shafts. Notches 15 in the peripheral edges of the fins 13 allow the coolant to pass between adjacent grooves 14. In the modification shown in Fig. 4, a carbon ring 33 slidable on pins 34 on a fixer ring 35 is urged by springs 38 into contact with a metal ring 36 on the shaft 37 and the rings 33, 36 are cooled by fluid admitted at 40, and flowing along the outside of a cylinder 41 to the region of the contact faces and then returning to the interior of the shaft housing through an annular space between the cylinder 41 and the shaft 37, the ring 36 having a deep groove 42 to increase the cooling surface.

Title: Valve mechanism for automatic control of a number of fluid motors
IPC: F15B11/16
Filed: 1974-06-18
Abstract: 1470696 Hydraulic control circuits HYDRAULIC INDUSTRIES Inc 18 June 1974 [26 Dec 1973] 27014/74 Heading F1P [Also in Division E1] In the circuit shown, Fig. 3, in which control valves 10, 11, 12 control rams 14', 15', 13', flow control devices 17, 18, 19 are provided through which the fluid supply to the control valves sequentially passes. Each flow device has two positions and in the case of flow control device 17 a first position, as shown, permits flow from a pump P through lines L1, 31 to the ram 14' and prevents flow to the other rams even if their control valves 11, 12 are open. In the second position, in which a spool 26 is moved to the right, the supply to the ram 14' is cut off and the flow passes to the next flow control device 18 and the ram 15'. The spool 26 moves to the right when the pressure in a chamber 42 reaches a predetermined value at which a relief valve RI opens, i.e. when the working pressure at the ram 14' rises to a predetermined value. The circuit is applied, as described to a back hoe, Fig. 2, and effects automatic digging. Valves 10, 11, 12 are opened as shown in Fig. 3 and ram 14' begins to extend, swinging arm 14 downwards. When the pressure in ram 14' reaches the pre-set limit, extension of ram 14' is arrested by the device 17 and ram 15' begins to curl the bucket 15 thereby reducing the leverage on the arm. If this results in the pressure in ram 14' falling below the pre-set limit the curling of the bucket is stopped by the device 17 and the arm 14 continues its downward movement. Alternatively, if the pressure in the curl ram 15' rises to the limit set by a relief valve R2 the device 18 prevents further extension of ram 15' and device 19 permits the lift ram 13' to extend. This reduces the resistance to the motion of the bucket and curling or movement of the arm 14 recommences.
