Title: An improved last-carrying head for footwear vulcanizing machines
IPC: B29D35/00
Filed: 1957-10-21
Abstract: 877,453. Footwear vulcanising machines. CAPDEVILA, G. M. Oct. 21, 1957 [Oct. 22, 1956], No. 32835/57. Class 87(2). A last-carrying head for footwear vulcanising machines comprises a body 30 rotatably mounted on a main body 10 and carrying at least one pair of lasts, (not shown), protruding therefrom at diametrically opposite locations, and means for rotating the body 30 between a number of angularly-spaced positions, the or each pair of lasts being mounted on a slide 67 transversely guided in the body 30 and movable to effect radial movement of the lasts at each of said positions of the body 30. The motor for rotating the body 30 is of the oscillating vane type and is formed by a cylindrical box 48 in which are fixed quadrant 56 and a rotatable quadrant 58, the latter being rotatable through angles of 180 degrees when there is but one pair of lasts, as in the embodiment described. In order to effect rotation of the quadrant 58, two holes 59 (one of which is shown in Fig. 1) are provided at opposite ends of the cavity formed by the fixed quadrant 56 and the box 48, each hole being connected to a pressure fluid source. One surface of slide 67 is provided with a circular groove 73 which engages a curved rib 74 on a lifting member 75 connected to a pressure fluid-operated piston 83. The raising of piston 83 consequently raises the slide 67 and when this reaches its upper position the groove 73 is centred about the axle of the body 30 and ready to revolve when the motor 48 is operated to reverse the relative positions of the lasts. In cases where the pressure of the piston 83 is insufficient to resist the upward reaction of the vulcanising mould, the slide locking device shown in Fig. 3 is used. This comprises a rod 114 which passes through a guide 113 in a cylinder 110 attached to the main body 10, through a hole 124 in the slide 67, and into a socket 125 on the other side of the main body 10. The cylinder 110 is held in place by a cap 111 screwed into the body 10. By applying pressure fluid through a conduit 119 or radial holes 121, the rod 114 is pushed into or out of locking position. The pressure fluid is fed to the various hydraulic mechanisms by means of any conventional valve combination operated manually or by means of sequential feeding distributer devices.

Title: Surface generating method and apparatus
IPC: G05B19/31
Filed: 1969-07-08
Abstract: 1279871 Lapping ITEK CORP 8 July 1969 [26 July 1968] 34251/68 Heading B3D [Also in Divisions G3 and H2] Independent relative movement in two directions between a surface generating means and a workpiece, e.g. a lap and a flat optical surface, is controlled by a programmed data source, and the drive system is such that a predetermined amount of overshoot occurs when motion is required to stop or change direction. The object is to ensure that the path taken by the lap is a series of smooth curves. The workpiece 15 is theoretically divided into hexagonal areas, each approximately the size of the lap. Each area is defined by the co-ordinates of its centre and the programme comprises a sequence of these be-ordinates, in digital form, the sequence being determined as disclosed in Specification 1,253,716 as being the best path for the lap to follow to remove previously measured irregularities. Thus, the programmed path is a series of straight lines joining the centres of predetermined areas, but the drive system, which moves the lap 12 and its rotating motor on orthogonal rails 17, 17<SP>1</SP> and 20, 21 above the workpiece includes an integrator and selectable resistors in each (X and Y) motor speed control circuit whereby the acceleration and deceleration of each motor is predetermined. Signals representative of the X and Y position of the lap from encoders are fed into a buffer register (Fig. 6, not shown) from which they are compared with the next desired position co-ordinates stored in an active buffer register from the programme tape. The desired position co-ordinates are changed when both the X and Y position has been reached or passed by the lap. Thus, starting at 305 in Fig. 10 the lap is moved to 307, using X drive only. At 307 the next command requires further movement in the same direction for X and also upward movement for Y. The X drive continues at full speed but Y has to accelerate so the lap follows the curve shown to 308, then with both drives at full speed to 309 which is the X destination but not the Y. Therefore, X decelerates, overshooting point 309 in X, while Y continues, to produce curve 311, until at 312 the Y destination also is reached, whereupon the next pair of co-ordinates on the programme are fed into the active buffer store so that movement continues along the line shown. The drive motors are "pulse motors" energized with square waves at a frequency determined by the speed control signal, and in a direction determined by logic circuits (Figs. 7 to 9, not shown) and the computer circuits include parity control and fault detecting arrangements shown in block form only. Motion is stopped by a switch 341 if the lap exceeds the edges of the workpiece ; this is actuated by a cord 335 attached to the centre of the lap carriage. The workpiece is mounted on a carriage 16 separate from the frame of the machine, but securable thereto for working; this facilitates removal for measuring and accurate replacement. The lap carriage has two supports on rail 17 and one on rail 17<SP>1</SP>.
