[Class 69 (iii)] A spraying device for attachment to tractors having implement carrying means capable of being raised and lowered, comprises a laterally extending arm having central and outer booms 20, 28, carrying spray lances 35, said outer booms 28 being hingedly attached to the central boom such that movement of the latter from the operative position (in which the booms are in line) under control from the tractor, automatically causes the outer booms to swing inwards. Secured to the tractor is a frame 13 having vertical end pillars 14 on which sleeves 25 are slidable and rotatable. Rotatable in a guide-way in each sleeve are arcuate members 23 carrying the central boom, the sleeves also having the outer booms rigidly attached thereto, said outer booms being further supported by tie rods 34 fixed at their inner 'ends to guide rods slidable within the pillars 14. Also secured to the boom 20 are push arms 21 in turn attached to the hydraulicallyoperated links of the implement raising and lowering means, the actuation of which causes boom 28 to be raised together with the sleeves 25 which are caused to rotate by having a pin engaging helical guides 31 in each pillar 14, carrying with them the booms 28. Spraying fluid is supplied from a tank on the tractor through rigid tubes 44 and flexible tubes 41, 42. Connected in the fluid supply and secured to the frame 13 are valves 45 which automatically cut off the supply of fluid when the central boom is raised. According to the first Provisional Specification in a modification, the central and outer booms may be rotatable axially so as to raise the spray lances through 180 degrees, such movement causing the outer booms to swing inwards through 90 degrees by means of bevel gears secured to the outer ends of the central boom and the inner ends of the outer booms.

The first button SB, Fig. 11, having been positioned in the button-clamp 18 and attached to the work in the usual manner the operator lifts the presser-arm and then pulls on the work. The lifting of the arm brings a button B into engagement with feeler pins 5 spring-mounted in a rotor 3. The attached button SB in moving along the shoot engages a pin 11 projecting from a drag-link u pivoted to a sliding rack w which rotates, through gearing, the rotor 3 so that the feeler pins engage in holes in the button. The rack w moves until a shoulder 13 engages a carriage s supporting the rotor 3 and slidable on a shaft g mounted on the sewing-head. This carriage is previously locked by a lever 14 engaging a slot 15. As the pull on the work continues the carriage s is unlocked and moved, taking the rotor with the engaged button till the latter is gripped by the clamp 18. The 'pin 11 drops into a side slot 12 so that the attached button no longer exerts a pull on the side. The work is then further moved to the button-attaching position and the presser arm allowed to fall, the pin dropping out of the slot 12 and the carriage being returned by a spring 19. A finger-piece 11 is provided on the link u to permit of manual movement of the slide to place the first button.

Abstract: 500,947. Control of D.C. motors; electricity supply. MALEY, A. W., and TAUNTON, E. M. June 16, 1937, No. 16743. [Class 38 (iii)] [Also in Group XXXV] Regenerative braking.- A generator driven at varying speeds by a vehicle and supplying a source of substantially constant voltage, which generator may be the vehicle driving motor acting regeneratively is connected to the source through a contactor 5, Fig. 1, the closing of which is governed by a circuit containing a rectifier 8, and supplied by the difference between the generator voltage and the voltage of the source. The contactor 5 has a winding 7 connected in series with the rectifier 8 between the supply and generating machines 1, 2. When the generated voltage exceeds the supply voltage by a predetermined amount the winding 7 is energized sufficiently to close the contactor, whereupon tho winding and the rectifier 8 are shortcircuited or connected in shunt to a series winding 6. The winding 6 holds the contactor closed until the generated current falls to a predetermined value. The circuit including the rectifier 8 may contain contacts 9, Fig. 2, of a contactor closed by a coil 10, when the generated voltage reaches a value corresponding to the probable minimum value of line voltage. In a modification this contactor is arranged to be normally closed and held open by a coil energized through a rectifier by an excess of line voltage over generated voltage. This contactor may additionally or alternatively control the connection between the supply and the generating machines. A single winding only on the contactor 5 suffices when the winding is connected in shunt to a resistance in the main circuit by the closure of the contactor. For regeneration the machines 1, 2 may be connected as described in Specification 461,881.
