Title: Improvements in lift mechanism for agricultural implements mounted on tractors
IPC: A01B63/10
Filed: 1952-06-16
Abstract: 711,251. Agricultural implements. ALLIS-CHALMERS MANUFACTURING CO. June 16, 1952 [June 29, 1951], No. 15114/52. Class 6 (1) Lift mechanism for independent tool mountings on a tractor comprises a single power device connected through lost-motion means to adjacent actuating arms on a transverse shaft in two sections independently rotatable on the tractor, and hand-lever means for each tool mounting for setting stops which coact with further arms movable with the shaft sections. Fig. 1 shows the invention applied by lifting, by chains 68, 31, assemblies of ganged hoes 27, with associated plant shields 28, supported at each side of the tractor by parallel-motion links 24. The links are connected to fixed arms 19 clampable along a transverse draft bar 16 at the front of the tractor. The lift control or setting gear is carried by a transverse frame 39 bolted to the tractor body 3 and supporting right and left hand levers 48 by sleeves 51 turning on a hollow shaft in two independent sections 59, 61 fast with arms 62, 63 from which the tool gangs on each side are suspended by chains 68. The shaft sections 59, 61 carry respectively power actuating arms 69, 71 between which the pin 81 on the piston rod 78 of the power cylinder 77 is connected through the medium of lost-motion arcuate slots 72 in each arm. For simultaneous raising of the tools on each side, the arms 69, 71 may be connected by a pin passed through holes 93. The power cylinder receives fluid under pressure from pump 82 through pipe 83 under the control of lever 84.

Title: Improvements in apparatus for playing a game of skill
IPC: A63F9/14
Filed: 1927-06-08
Abstract: 284,132. Rogers, R. C., (Scandinavian Export Agency Aktieselskabet). June 8, 1927. Manipulative speed competitions, mechanical apparatus for.-In an apparatus for playing a game of skill, of the type comprising a number of dolls with rubber heads or bodies exploded by air supplied intermittently, the explosion of a doll actuates apparatus to expel air from the remaining dolls. In the form of apparatus shown, each player rotates a separate hand-wheel 2 attached to a centrifugal governor 4 carrying a disc 6. The disc is provided with a cam 8 which during the rotation of the disc depresses alternately two plungers 9, 10 so as to open, in turn, a pair of valves 16, 17. A puff of air is thus allowed to pass from a compressed air supply 20 to a pipe 25 and thence to a rubber doll's head 32. The rapidity of the puffs of air, and consequently the rate of inflation of the doll's head, depends upon the speed of rotation of the hand-wheel 2, but if the hand-wheel be rotated too quickly the governor raises the disc 6 and thus diminishes or entirely cuts off the supply of air. The player who first explodes his doll's head is the winner. A block 33 carried by a spring 34 is arranged upon each doll's head, and when the head explodes the spring strikes a rod 38 and thereby rotates a shaft 40 (common to all the doll's heads) so as to displace a catch 48 and allow a pair of spring-pressed arms 44 to rise. The arms carry a rail 43 extending beneath a row of valves 41, one valve in each supply pipe 25. The valves are thus all opened immediately a doll's head explodes, thereby preventing the explosion of further dolls' heads by the continued rotation of the hand-wheels. The exploded head may be removed and a new head fitted by first lowering a clamping cone 30 by means of a lever 37.

Abstract: 529,139. Washing drinking vessels &c. VARLEY, E. V. May 23, 1939, No. 15291. [Class 138 (i)] Cups, mugs, drinking glasses and the like are placed on eccentrically mounted brushes 9, Fig. 1, on spindles 7 which are rotated by spur gearing 11 driven from a hub 2. The cups &c. are passed between pairs of stationary brushes 3 which clean the outsides. The cups are retained on the brushes 9 by loops 13 carrying brushes 14. Each loop, 13, Fig. 4, is pressed into the retaining position by a spring 19 and is turned back from this position by a curved cam 21 engaging a projecting arm 22. The arc of travel during which members 13 are held out of position enables an operator to remove a cup and replace it by another.

Abstract: 1384484 Photo-flash apparatus GTE SYLVANIA Inc 29 March 1973 [12 June 1972] 15292/73 Heading G2X A selective actuating mechanism for use with a row of percussively-ignitable flash-lamps and a plurality of pre-stressed strikers mounted on a support 12, comprises a longitudinal guide located parallel to the row of flash-lamps and a slidable member which is successively indexable along the guide and is provided with means for sequentially releasing the pre-stressed strikers to fire successive flash-lamps in the row in response to the indexing. As shown a flash-lamp assembly for insertion in a camera flash-cube socket comprises two rows of four-flash-lamps 21-(28) facing in opposite directions and associated prestressed strikers (31)-(38), two guide channels 76, (82) and two bars 68, (84) which slide in the channels and have a series of ramps 71-74, (91)-(94) for releasing arms 64 of the prestressed strikers to fire the associated flash-lamps. Indexing is effected by engagement of ratchets 96 on the bars with a camera member 100 which is raised when the shutter is operated and thus causes the bar (e.g. bar 76) to move to the right whereby one of the ramps releases a striker arm; the bar is prevented from returning by a spring ball latch assembly 104-108. After the first row of flash-lamps has been fired, the assembly is turned around.

Abstract: 1501511 Abrasion wheels INOUE-JAPAX RESEARCH Inc 14 April 1975 15313/75 Heading B3D [Also in Division C7] A rotatable, electrically conductive, abrasive wheel electrode 1 for electrochemically grinding a workpiece has a machining surface 11 comprising electrically non-conductive abrasive material in a matrix of electrically conductive material, formed to a profile complementary to that required to be formed in a workpiece wherein the matrix material is removed in the circumferential position to a depth which varies to define an electrical conductivity pattern such that the conductivity is less in portions facing in directions the radial component of which is minor relative to the axial component, than in the remainder. Preferably the depth of removal in at least part of the radial directionfacing surface is 10 to 100 microns, and in the axial direction-facing surface is between 100 microns and 10 mm. The material may be removed by electrochemical dissolution using a further treatment electrode 3, or by chemical etching, mechanical brushing or spark erosion. The surface may be prepared by mechanical dressing. As shown, the electrode 3, e.g. a block of graphite or semi-sintered metal, vertically movable by a cylinder-piston/motor arrangement 4, is first displaced downwardly and ground mechanically by the rotating abrasive wheel electrode 1 until the electrode 3 has a shape complementary to the machining surface 11, then withdrawn to space it radially from the machining surface by a distance L (Fig. 4) of between 0À1 and 10 mm, and material is removed electrochemically, by delivering electrolyte upon the rotating surface 11 via nozzle 5 and closing switch 7 connecting power supply 6. A monitoring electrode 10 may be provided juxtaposed the wheel electrode and connected via a selectable resistor 9 (Fig. 8) to an electromagnetic coil for controlling the switch. The further electrode may be a stylus electrode (403, Fig. 9) arranged to be traversed in a first direction and second peripendicular direction as programmed by a numerical control device.
