Filed: 1959-05-12
Abstract: <PICT:0887340/III/1> Apparatus for coating the vertical walls of a succession of articles 1 carried in spaced relationship at a substantially constant rate by a conveyer 2, the said walls being those substantially at right angles to the direction of travel, comprises support arms 6 and 7, pivoted about a horizontal axis provided by shafts 8 and 9 and providing a track along which a spray gun carriage 13 is movable.  Means responsive to the presence of an article, e.g. a photo-electric cell 55, and suitable control gears, causes the carriage 13 to complete an excursion from an initial position outside the path of the articles 1, across that path, and back to its initial position, and actuating means, e.g. the cylinder 49 and piston 51, move the arms 6 and 7 through an angle, predetermined by stops 46 and 48, about the said horizontal axis, when the carriage has crossed the path of the articles.  The angular positions of the arms and the speed of the carriage are such that the spray guns 14 are maintained at a constant distance from the wall being coated as coating is effected.  Timing means is provided for regulating the actuating means and the period during the excursion when the guns project coating material.  The movement of the spray gun carriage 13 is obtained by mounting it on trolleys 10, 11, running on rollers 12 along the arms 6, 7.  Endless chains 18, 24 run on sprockets 15, 16 and 21, 22 on the two arms 6, 7 respectively, and carry drive dogs 19, 25 which engage in slots 20, 26 in the trolleys 10, 11.  The chain 18 is driven from a motor 31 and the drive is transmitted to the chain 24 through further chains and sprockets and a cross-shaft 35.  The carriage 13 may be pivoted on the trolleys 10, 11, and biased so as to maintain the sprays horizontal.  A safety-probe 78 is provided to stop the machine if the articles approach the spray guns too closely.  In a modification, the gun carriage may be mounted cantilever fashion on a single trolley.  The apparatus may be adapted to coat either the front or the rear walls of the articles 1, or both.

Title: Improvements in or relating to speed regulating devices
IPC: G05D13/00
Filed: 1929-05-29
Abstract: 334,214. Hecht, N. F. S., and Alexander, D. P. May 20, 1929. Electric governors. - In a speed-regulating device which when a mechanism tends to increase speed a reactionary torque is set up absorbing energy and tending to neutralize the change of speed, mechanism is provided whereby, if the speed departs from that of a timing device, the reactionary torque is varied so as to synchronize and phase the two devices. The armature 1 of the shunt motor to be controlled is connected in series with the resistance 6 and windings 5 of a regulating device 50. The regulating device 50 comprises a mass arranged to be moved by centrifugal force against the action of springs, the displacement of the mass serving to bring into action a variable reactionary torque due to electric eddy current braking. Connected to the motor through reduction gearing is a commutator 8 with three brushes 9, 10, 11, the brush 9 being always in contact and brushes 10 and 11 contacting with a strip 13. A circuit is made across the mains through a clock pendulum 16, relay 14 and the brushes 9 and 10, 11. The arm 15 of the relay makes and, breaks the circuit of a resistance 18 connected in parallel with the coils 5. When the pendulum and brush 10 contact together, the braking effect of the device 50 is reduced thus causing the motor to accelerate and when the pendulum and brush 11 contact together, the circuit is broken by arm 15 moving to the left. Thus the motor 1 is kept in synchronism and phase with the timing device. Specifications 189,366, [Class 40 (v), Wireless signalling &c.] ; 233,828, [Class 139, Watches &c.]; 292,194, [Class 38 (iii), Electric motor control systems &c.], and 309,217 are referred to.

Title: Improvements in or relating to hydraulically actuated loading mechanism for refuse collectors
IPC: B65F3/18
Filed: 1945-07-05
Abstract: 602,108. Refuse-collecting vehicles. SCAMMELL LORRIES, Ltd., HUGH, P. G., and WATTS, L. D. July 5, 1945, No. 17184. [Class 108 (i)] [Also in Group XXX] Automatic control mechanism for hydraulically-actuated loading mechanism for refuse collectors of the type comprising a travelling refuse scoop includes means responsive to build-up of hydraulic pressure which occurs when the carriage reaches the limit of its travel in the direction for carrying refuse into the interior of the collector to reverse the direction of drive, so as to return the carriage automatically to the refuse-receiving position, and means for stopping the driving mechanism when the carriage reaches the refuse-receiving position. As illustrated, the control mechanism is applied to a refuse-collecting vehicle with loading mechanism of the kind described in Specification 467,479 in which a scoop 6 is moved vertically in a refuse receptacle at the rear of the vehicle and horizontally along the top of the vehicle, the scoop being operated by hydraulic mechanism as described in Specification 602,107. The scoop-operating mechanism is controlled by a valve 14, operated by a spring or weight-loaded lever 35 which is raised to the position " Y " for moving the scoop in the forward direction, and lowered to the position " X " for driving the scoop rearwardly. To commence the cycle of operations, the lever 35 is moved to position " Y " and the scoop moves to the end of its travel at the front of the vehicle, or to an intermediate position if the vehicle is nearly filled with refuse. Pressure then builds up in the control valve 14 to overcome the force exerted by the spring of a plunger 32, which is forced outwardly to release a catch 38 and allow the lever 35 to move to the position " X, " and return the scoop to the starting position. When the scoop reaches the bottom of the refuse receptacle it comes into contact with a spring-loaded bar 39 connected by a telescope link 41 to a lever 42, which returns the lever 35 to its intermediate neutral position. An adjustable stop 43 is provided to enable the lever 35 to be set accurately in the neutral position.
