IPC: B23Q35/20
Filed: 1957-05-30
Abstract: 862,540. Copy-milling; copy-planing. BUFFOLI, M. May 30, 1957 [June 5, 1956], No. 17128/57. Class 83 (3). A machine for cutting cams comprises a tool G rotating about, or reciprocating along, a fixed axis, a rotary blank-support 46, and a mechanical drive to rotate the support and to move it to generate the cam, the drive including an oscillatable lever 5 having at least two pivot points 6, 11, the first of which is displaceable along the lever as a function of the cam slope, and the second being displaceable with the lever. The machine is for cutting a cam E, Fig. 7, which is to co-operate with a follower 50 mounted on a lever 51, the other end of which carries a gear sector 52 engaging a rack 53 on a machine slide. The axially adjustable cutter represents the follower. The movement of the work support represents the relative movement of the cam with respect to the follower. The radius L of the sector is represented by a lever 36, Figs. 2 and 4, pivoted at 37 to the centre of a table c and engaged by a pin 40 on an adjustable slide 38. When the table c is rotated, tapes 32 thereon move a slide 34 carrying a pin 35 engaging the lever, and the pin 40 is moved with or against the force of a spring 41. Movement of the slide 38, indicated by a scale 48, represents the movement of the rack 53. A slide A is adjusted so that the axis of oscillation V of the table c is at the correct distance L from the cutter axis, representing the distance between the axis of the follower and the axis of oscillation of the lever, and indicated on a scale 43. The axis 29 of the plate 46 carrying the cam blank E is then set at the distance I from the axis V by adjusting a slide F against a scale 45, the distance I representing the distance between the cam axis and the axis of oscillation of the lever. A worm 3 is then rotated to swing the table c, and a hand wheel 22 is rotated to adjust the blank E, through worm gearing 28, to an initial position corresponding to the point at which the follower engages the point of maximum diameter of the cam. To generate a portion of constant diameter on the cam, a main pivot 6 engaging the lever 5 is adjusted by a screw 8 to be coincident with a pivot mounted on a rack-toothed slide 4 meshing with teeth on the table c. When a screw 13 is then rotated, a block 12 carrying the pivot 11 rotates the lever 5 about the common pivot 4, 6, without causing rotation of the table c. A clutch 27, which is engaged one way or the other according to the direction of cam rotation, causes rotation of the cam through an angle indicated on a scale 46.

Title: Improvements in valves
IPC: F25B41/06
Filed: 1940-12-03
Abstract: 543,951. Fluid actuated valves. DILLMAN, E. J., and COWLEY, W. E. Dec. 3, 1940, No. 17191. [Class 135] In an expansion valve, for refrigerating apparatus, having an element responsive to the vapour pressure of a liquid in a bulb element, the warm liquid refrigerant entering the valve casing is utilized to maintain the vapour pressure responsive element at a higher temperature than the bulb element. As shown, the casting 1 has an upper portion 3 and valve casing 4 separated by a narrow neck 2 which prevents the flow of heat from the portion 3 to the casing 4. Warm liquid refrigerant enters the part 3 at 12 and passes to the valve port 15 via a circuitous path in the part 3 and ducts 13b, 13. To the part 3 is secured a diaphragm 50 having deflection limiting plates 51, 52, on opposite sides. Rods 61 connect the diaphragm 50 to a slidable valve carrier 27, the clearance around the rods 61 allowing the space 65 below the diaphragm to be subjected to the gas pressure existing on the outlet of the valve 36. The space 66 above the diaphragm is connected to a bulb 67 which is subjected to the evaporator temperature. The coned valve element 36 is rendered self-centring by being fixed to a sleeve 32 having a radial flange 33 resting upon a flange 31 of a sleeve 29 fixed in the carrier 27. The flanges 31, 33, which are pressed together by a spring disc 40, are connected by upstanding tags 37 on flange 31 entering clearance notches in flange 33. The diaphragm 50 and carrier 27 are acted upon by springs 57, 42, the latter being adjusted by screwed member 19. The valve 36 is thus controlled by the differential pressure acting on the diaphragm 50, the chambers 65, 66, being kept warm by the liquid refrigerant flowing through space 11 of casing part 3 to prevent condensation of the vapour in the chamber 66.

Title: New or Improved Method for Producing and Regulating Sliding or Rotary Motion by Differential Mechanism Driven by Electric Motors Differentially Controlled.
Inventor: MARTIN ALBERT
IPC: H02P5/695
Filed: 1916-12-01
Abstract: 112,963. Martin, A., Whitfield, J., Campbell, T. B., and Campbell, A. J. Dec. 1, 1916. Systems depending on the use of two motors.- Two motors, differentially controlled, are connected by worm gearing to differential screw or mitre gearing to give rectilinear or rotary motion. In the arrangement shown in Figs. 1 and 3, the motors 1, 2 drive worm-wheels 4, 7 respectively, the wheel 4 being secured to a sleeve 5 threaded internally to suit the screw spindle 6, which can move axially through the wheel 7 but is feathered to rotate it. A bell-crank lever 8 on a pivot 9 is connected by a link 13 to a valve or governor, and a lever 10 on the pivot 9 is connected to a slide rod 11 which is also connected by levers 12, 21 to the rheostat arm 24. The lever 12 is also connected by the rod 19 to a rocking lever 18 operated by series and shunt electro-magnets 14, 16. As the prime mover of the generator 33 is started up, the motors 1, 2 run at equal speeds and there is no axial movement of the spindle 6. With no load on the generator, the shunt solenoid 16 operates the rocking lever 18 to pull the rod 21 and move the rheostat arm 24. This varies the strengths of the motor fields and causes the motor 1 to run faster and the motor 2 to run slower. The spindle 6 moves axially and operates the link 13 to close the governing valve. With load on the generator, the series solenoid 14 comes into action and this opposes the action of the solenoid 16. In a modification, differential mitre gearing is employed instead of the screw gearing.
