Title: Improvements in or relating to the control of the grit feed of grit laying apparatus
Inventor: ROBSON ERNEST GEOFFREY
IPC: E01C19/20
Filed: 1957-11-05
Abstract: 885,126. -Grit distributer. AVIATION, MINISTER OF. Feb. 5, 1959 [Nov. 5, 1957], No. 34471/57. Class 6(1). [Also in Group XXIX] The rate of feed of grit from a hopper mounted on a grit laying vehicle is controlled by a gate the opening and closing of which is effected by a servomotor controlled by the speed of the vehicle. In one embodiment, the grit 2 in a hopper 1 passes on to a conveyer belt 5 driven by the vehicle at a rate determined by the setting of a gate 4 pivoted at 7 and actuated by a doubleacting hydraulic motor 38 controlled by a pilot valve 20 which is actuated by a solenoid 30. The solenoid is controlled by a switch 13 consisting of a pair of contacts 15, 16 mounted on a sector 14 and movable about the pivot 7 by an arm 12 carrying a roller 11 which coacts with a cam 10 movable by a centrifugal governor 9 driven by the vehicle. The arrangement is such that an increase or decrease of speed of the vehicle causes movement of the sector 14 to bring either of the contacts 15, 16 into engagement with a contact 18 to complete an electrical circuit to the solenoid to move the pilot valve 20 in the direction for increasing or decreasing the opening provided by the gate 4, the movement of the latter also moving the contact 18 to an insulating portion 17 of the sector 14 so that the valve 20 is returned to its neutral position and the gate 4 brought to rest at a position corresponding to the changed speed of the vehicle. A number of cams 10 may be provided, each having a different contour for controlling the opening of the gate in accordance with the nature and size of the grit being fed from the hopper. These cams may be mounted or formed upon a plate arranged transversely of the vehicle and manually operated to bring the required cam into engagement with the roller 11. In a modification, four cams and follower rollers 11 together with the switch gear 15, 16, 18 &c. are provided and a manually operable switch is employed for selecting any one cam for control of the solenoid operated valve 20. In a further modification, a hydraulic pump driven at a speed proportional to that of the vehicle and delivering fluid to a spring- loaded piston is employed instead of the centrifugal governor. The spring-loaded piston operating through a rack and pinion gear actuates a rotary cam having a follower which operates the pilot valve controlling the gate motor. Movement of the gate causes movement of the housing of the pilot valve to bring the gate motor to rest at a position corresponding to the speed of the vehicle. A number of differently contoured cams may be provided arranged to be brought selectively into engagement with the rack. Specification 706,035 is referred to.

Abstract: 466,520. Clamping - mechanism for cutting - machines. THORNTON, A. A. (Seybold Machine Co.) Dec. 12, 1935, No. 34484. [Class 31 (i)] A clamping-mechanism for holding stacks of material in a guillotine machine includes a system of levers and springs which turn as a unit until the clamp engages the work when part of the system remains stationary and the remainder moves round a pivot thereon to apply pressure to the work. The system comprises a cam lever 22 which is rocked on a shaft 23 by an eccentric 16, an eccentric strap 16a and a connecting rod 18 and has a cam surface 22a including a notch 22c to co-operate with a roller 30e carried by a double bell-crank lever 30. The latter is pivoted on levers 31 loosely mounted on the shaft 23 by holes 31u, being normally held in the position shown in Fig. 2 by springs 31b bearing against washers 24 on the shaft 23. A shoe 33 co-operating with an arcuate track 34 is pivoted to the lower ends of the levers 31. Springs 27 mounted on rods 25 carried by the washers 24 on the shaft 23 bear against a bar 26 on the bell-crank 30 to hold the roller 30e up to the cam 22a. The lower ends of the bell-crank are connected by pins 38b and slots 30d with lower hinge members 38 which are pivoted at 37 to upper hinge members 36; the upper and lower hinge members are coupled together by rods 40 and are urged apart by powerful springs 42. The upper hinge members are connected by links 46, levers 48, 50 and pull rods 52 to the clamp. In operation, a treadle is depressed to start the driving shaft 10 and the lever system moves as a unit clockwise about the shaft 23 until the clamp engages the work ; then the springs 27 yield, the roller 30e rides out of the notch 22c, and the levers 31 move downwards against the springs 31b so that the shoe 33 is forced into engagement with the track 34. The bell-crank 30 then rocks about its pivot 35 which is now stationary and operates through the hinge members 36, 38, links 46, levers 48, 50 and pull rods 52 to clamp the work with a force depending on the springs 42.
