Title: Improvements in and relating to Centrifugal Machines and the like.
Inventor: HAMILL JAMES
IPC: B04B1/18
Filed: 1916-02-14
Abstract: 102,407. Hamill, J. Feb. 14, 1916. Density separators. - One or more. hydraulically-operated valves are arranged so as to discharge material of less or greater density than the liquid without discharging the whole contents of the drum. A strainer may be fitted so as to drain off liquid from the material of greater density. Fig. 1 shows a machine for separating material of greater and less density from a liquid. The former is collected at the extreme diameter of the double-conical drum and is discharged through one or more valves e<1>. The lighter material is collected in a U-shaped annulus c<10> positioned near the annular wall of liquid and is discharged through one or more valves e through conduits e<11>. The liquid passes away through orifices a<4>. A discharge valve is shown in Fig. 2. It comprises a removable seating c<3> in the drum a, against which the plugged tube c<2> is seated by centrifugal action. The end of the tube e<2> nearer the axis of the drum has a flange e<6> and a sliding piston e<7> fitting the cylinder c'. The valve is opened by admitting liquid from the pipe d<2> to one or other of the channels d, d<1>, wherein it becomes subjected to centrifugal pressure and acts on the piston e<7>, forcing it and the tube towards the axis of the drum and opening the valve. The liquid from the cylinder c' passes out through the orifice e<8> to the outlet e<3>, or may be discharged into the liquid in the drum. The orifice e<8> is normally closed, either by the piston e<7>, or by the guide-flanges of the cylinder c<1>. In a modified machine in which water held in a heavier solid material may be drained off, the valve tube is encased in a strainer or filter, through which the liquid is discharged, the dried mud being afterwards removed from the drum by mechanical means.

Abstract: 232,354. Griffiths, A. V., and Automatic Scale Co., Ltd. Jan. 28, 1924. Automatic-feed weighers.-Relates to an automatic-feed weigher of the kind in which a bicompartment, oscillating receptacle is suspended from one end of a weigh-beam, and comprises the provision of a lever which controls the movement of the supply-gate and is in operative contact with mechanism adapted successively to effect the cutoff of the dribble-feed and the release of the receptacle. As shown in the Figure, an oscillating receptacle 5 is carried by a cradle 6 suspended from one end of a beam 7. The receptacle is divided into two parts by a partition 5a and is provided with discharge openings 5<b>, 5<c> adapted to be closed by gates 6<b>, 6<c> attached to the cradle 6. A spindle 9, rotatably mounted in the frame of the machine carries a weighted lever 10, supported by the cradle 6, and a second lever 12 attached at its upper end to a gate 13 adapted to close the supply hopper 14. An arm 15 projecting from the lever 12 engages a release lever 16, to which is secured a cylinder 17 containing a rolling ball. As the material enters the receptacle 5, the cradle drops, the feed-gate closes and the arm 15 depresses the lever 16 into contact with a tooth 19<a> on a weighted trigger lever 19. The feed continues through a small aperture in the gate 13 until the trigger lever is depressed by a pin 21 projecting from the cradle. The lever 16 when freed, strikes the arm 23 of a bell-crank lever, thus lifting the other arm 24 out of engagement with a catch 25 on the receptacle and allowing the receptacle to oscillate and discharge. The feed-gate reopens as the receptacle rises and the cycle of operations is repeated.

Title: Improvements in gravity controlled liquid applying device
IPC: A46B11/00
Filed: 1951-01-29
Abstract: 686,576. Gravity controlled liquid applying devices. JOCKERS, H. W. Jan. 29, 1951, No. 2209/51. Class 19. A liquid applying device comprises a casing having a main chamber and an auxiliary chamber, a valve passage communicating with said chambers, a valve controlling this passage, a discharge opening in the casing, a brush movable through the opening at the end of said valve and a weight within the main chamber having a flexible connection with the valve. The component parts are arranged so that a metered feed of the liquid is obtained. In the Figures a tubular casing has a body portion 1 closed at its lower end 2 and at its upper end by a casing section 3 so as to form a liquid receiving chamber 4. The inner end of the casing section is chambered as at 5 with the walls converging at 6 towards a passage 7 in a bushing 8 having a press fit in 3. The passage 7 merges into a discharge chamber 9 which leads to a discharge outlet 10. A rod 11 has near its outer end an annular groove 12 which forms valve portions 13 and 14 which have a working fit in the passage 7. A brush 15 is secured in the outer end of 11. The inner end of 11 has a portion of reduced diameter 16 to receive one end of a spring 17, the other end of which engages a reduced portion 18 of the rod 19 so that the rods 11 and 19 are connected by a flexible connection. The rod 19 is preferably of greater diameter or weight than that of the rod 11. The inner end of the rod 19 has an agitator 20 fixed to it. To prevent the brush from spreading during shipment a sleeve 22 is slipped over it. A cap 23 is in threaded engagement at 24 with the casing and seals the discharge outlet 10. When the cap is removed and the device is turned from the upright position in Fig. 1 to the inverted position as in Fig. 2 the weighted brush moves through the opening 10 and the valve rod 11 moves causing the valve ports 13 to advance in the passage 7. The groove 12 also advances thus permitting fluid to pass from 4 into the passage in restricted quantity and thence into the auxiliary chamber 9a. When the valve rod reaches the extent of its movement the spring 17 contacts the casing to limit the forward movement of the valve rod. When the casing is returned to an upright position the weighted brush is retracted within the casing. Specification 684,857 is referred to.

Title: Improvements in and relating to electrical sorting machines for sorting perforated cards for statistical and the like purposes
Filed: 1922-01-26
Abstract: 189,738. Bull, F. R. Nov. 28, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Compiling and tabulating statistics mechanically.-A machine for sorting perforated statistical cards comprises a shoot which moves across the direction of, and synchronously with, the travel of each card, so that when a circuit is completed through a perforation in a card the shoot is held so as to deliver the card to the appropriate compartment. The shoot h, Fig. 1, is rigid with a toothed sector f rotating about axis h<1> synchronously with the travel of the card between the rollers c, e and past the contact brush d. When this brush makes contact with the block d<1> through a perforation, for example number 7, the pawl g is released and holds the shoot h over compartment i<7>. Cards unperforated in the column passing the brush d are sorted into the end compartment i<10>. In a modification the upper parts of the compartments are formed with flaps k<0> to k<9>, Fig. 2, which move synchronously across the path of the card so that when contact is made through perforation number 6, for example the pawl m is released and holds flaps k<0> - - k<6> so that the card is sorted into i<6>. The apparatus is adapted to calculate statistics by insulating the teeth of the sector f for contact with the pawl, which then operates the counter. Fig. 3 shows a construction for sorting cards perforated according to several numerical denominations by a single passage of the cards. Four wheels p<1> - - p<4> are mounted on a common axle p and each has a rib moving past and close to the sides of the ends of plungers q<0> - - q<9>. Each wheel has also teeth engaged by a pawl when the latter is released as in Fig. 1 by the contact of one of the brushes n on the four columns. The brushes are shown in a vertical line for clearness. To sort cards with the number, for example, 5410, the plungers q<5>, q<4>, q<1>, q<0> of the wheels are drawn back. A card having the number 5 in the first column will set the wheel p' in the position shown, and a card having the number 4 in the second column will set the second wheel p<2> as shown and so on. Only a card bearing 5110 will, however, set all four wheels as shown, so that the axle p may be moved axially to draw the nibs past the plungers and so bring a sorting compartment into position to receive the card.

Abstract: 930,837. Making battery plates; shearing. WINKEL MACHINE CO. Ltd. Jan. 22, 1960, No. 2511/60. Classes 83 (1), 83 (2) and 83 (4). [Also in Group XXX] Battery grids (Fig. 9) after formation in a mould, slide down shoot 14 and are brought resiliently to rest by plate 131, which is carried by bars 132 and is influenced by springs 94 to bear upon the upper surface of the grids. The bar 132 is raised by the operation of a cam on cam-wheel 100 acting via pivoted bars 96, 97 and rods 98, and the grid then slides downwards till it is brought to rest and is aligned by stop 142. Again, by operation of cam-wheel 100, stop 142 is raised to permit the grid to slide further to bring it between rollers 107, 108 which retard its passage. Roller 107 is then raised by operation of cam-wheel 100 via pivoted bars 152 and rods 151, so that the grid slides on to fixed shear member 111 and is checked and positioned by pivoted stop bar 121. The upper shear member 112 then descends to cut off the flash from the grid and in ascending, the pivoted hook 124 engages and lifts stop bar 121 to permit the grid to slide down plate 86. Grid-making machine (Figs. 2 and 7).-The mould is made in two parts, fixed part 31 and movable part 33. The movable mould part works in conjunction with knock-out pins 71 and ladle 55. All three movable parts are operated from shaft 26. Thus ladle 55 is operated in rod 59, bell-crank 61-62, and cam 66; and pins 71 and mould part 33 are operated by bar 42 which is cam-operated via lever 47, the bar 42 carrying U-member 38 which engages part 33 at 36 and also carrying bolts 78 which engage pins 71 at 77. In operation, the ladle is tipped to pour metal between the mould parts. Then the movable mould part is separated to allow the pins 71 to knock out the mould. Alternatively, the mould may be knocked out by levers 83 operated by handle 84.

Abstract: 563,507. Cam gearing; locking levers. JOHNSTON, R. H., and CAM GEARS, Ltd. Feb. 16, 1943, No. 2590. [Class 80 (iii)] Consists in means for reducing shocks that may be transmitted to the operating member from the operated member in gearing, e.g. for steering road vehicles, of the kind in which a worm is engaged by a follower freely mounted on a rocker arm. The worm 4 mounted on the steering wheel column 5 is engaged by a follower in the form of a cylindrical pin 6, with tapered end 7, mounted in a roller bearing 12 and a thrust ball bearing 13 in a bush 9 carried by an arm 11 on the rocker shaft 1. The pin is located by a spring ring 17 engaging a groove therein. With such an arrangement, it is found that the pin 6 always rotates in one direction when the gearing is actuated from the controlling member, and always in the opposite direction when an attempt is made to actuate the gearing from the controlled member, e.g. the road wheels. Accordingly a coil clutch 18 is provided to prevent rotation of the pin in the said opposite direction to produce sliding instead of rolling contact between worm and follower, thus introducing frictional drag. Specifications 223,963, [Class 80 (iii)], 342,770 and 422,346 are referred to.
