Title: Improvements in or relating to a machine for finishing by turning the ends of pipes
IPC: B28B21/92
Filed: 1959-04-07
Abstract: 856,220. Lathes. PASQUALE, C., GAMBERA, F., and REGIS, L., [trading as R.C.M. REVISIONE COSTRUZIONE MACCHINE]. April 7, 1959, No. 11733/59. Class 83 (3). A machine for turning, cutting-off and facing both ends of a pipe T simultaneously, comprises two machining-heads 2 adjustable along a bed 1, each head including a work-driving-spindle 3 and tool-holders 6, 6a supporting respectively a turning tool 13 and a cutting-off and facing tool 14, and the tool-holders being retractable longitudinally to permit lateral delivery of the abestos-cement &c. pipes T. The spindles are driven, through shafts 16, from a central drivebox 15, and the pipes are delivered along adjustable inclined guides 18, Fig. 2, by alternate operation of a pair of hydraulic release devices 20, 21. Rollers 24, on brackets 22 pivoted on vertical slides 25, support the work before and after machining, when it is held by expanding grippers 4 on the spindles, which are retracted towards the headstocks after release of the work. The brackets 22 are pivoted hydraulically into the lowered position during machining. Opposite sides of each headstock 2 have brackets 8, Fig. 3, guiding rods 5, 5a which carry the tool-holders 6, 6a. Hydraulic cylinders 9, 9a between the brackets effect fast traverse and feed of the tool-holders, which have lateral cylinders 11, 11a for pistons 12, 12a, Fig. 5, carrying the tools. Operation.-In the hydraulic circuit, Fig. 5, connections for only one of the headstocks are shown. The tool-holders 6, 6a are traversed by cylinders 9 until holder 6a for the cutting-off and facing tool 14 is stopped by a stop-screw 61, carried by rods 5a, engaging a stop 60 on a piston 59. The traverse of holder 6 for turning tool 13 is reduced to feed by a cam 42, which operates on a valve 40 to restrict the flow passage from the front of cylinder 9. Feed of tool-holder 6 is stopped by a stop 43 carried by rods 5, which also carry an abutment for closing a switch 44. Radial-feed of tool 14 occurs when a stop 56 on the rod 5a opens a valve 55, which allows escape of oil from the piston-rod end of cylinder 11a under the control of a regulator 54. An abutment 57 on the pistonrod operates a distributer valve 52, which connects cylinder 58 for piston 59 to exhaust, so that the feed of tool-holder 6a by cylinder 9a may be resumed for end-facing the pipe under the control of a regulator 53. At the end of this operation, an abutment on piston 59 closes a switch 62 in series with switch 44 and reverses supply valves 34, 35. This retracts the toolholders and tool 14 hydraulically, and allows a spring 15 to return tool 13.

Title: Improvements in or relating to methods of forming blocks of wood veneer laminations
IPC: B27L5/00
Filed: 1962-03-28
Abstract: 1,017,823. Woodworking.AARONSONBROS. Ltd., M. ALLAN, and M. BERMAN. March 26, 1963 [March 28, 1962], No. 11960/62. Heading B5L. A method of forming a V-shaped block of veneer laminations which may be sliced into sheets comprises stacking a plurality of laminations 11 with the grain running in parallel and adhesive between successive laminations, applying pressure only to a limited portion of the stack to form the V of the block in that portion, and subsequently applying pressure over the whole of the laminations which are thereby pressed together to form the V-shaped block. The block is formed in a press having an upper die 2, which can be raised and lowered by means 12, and a lower die 3 having a portion 4 which can be raised to the position shown by springs 5. In operation, the laminations with the adhesive therebetween are placed on the lower die and the upper die is lowered to engage the laminations while fluid pressure is supplied to cylinders 8 to maintain pistons 7 connected to the portion 4 in their upper position so that an initial pressing is effected to form the V in the block. Thereafter, the die 2 is moved further downwardly and the portion 4 retracted so that the whole area of the laminations is pressed. The so-formed V-shaped block may then be attached to the upper die by clips 13 to act as a die during the forming of a further block. The blocks may be sliced into sheets as described in Specification 1,017,824. The grain of the laminations may run normal or parallel to the length of the V of the block. In an alternative embodiment, the portion 4 and pistons 7 are formed as a whole.

Title: A Motorised Drive for a Rotary Electric Switch
Inventor: HAWORTH ROBERT
IPC: H01H3/58
Filed: 1966-03-19
Abstract: 1,165,731. Mechanical switches. SANTON Ltd. 14 June, 1967 [19 March, 1966], No. 12187/66. Heading H1N. A motorized drive for a rotary electric switch 8 comprises an electric motor 10 with a reduction gear 11, a clutch 12 on the output side of gear 11 to connect or disconnect the motor output shaft with a driving spindle 7a for the switch 8, a motor control switch 23 and control means 21 for opening and closing the control switch 23. Control means 21 is rotatable with spindle 7a and when rotation of the spindle has begun, rotating the switch from one angular position to the next, control means 21 closes switch 23 and opens it stopping the motor when the next angular position of the switch is reached. As shown, control means 21 is a disc with notches in its periphery corresponding with the angular positions of the switch and switch 23 is a microswitch with its actuating button nesting in one of the notches in the at rest position. When a remote mounted main switch (not shown) is closed the motor begins rotating and disc 21 rotates. As soon as disc 21 begins rotating the button of microswitch 23 rides out of the notch on to the disc periphery when the microswitch is closed. Microswitch 23 is in parallel with the main switch so that when the main switch is released microswitch 23 holds the motor energized until the disc 21 has turned so that the button of switch 23 falls into the next notch when switch 23 is opened and the motor stopped. To prevent over-running of the motor 10 the gear 11 is driven through a friction clutch which acts as a brake on the motor immediately it is de-energized. The motor 10 may be disconnected from the rotary switch spindle 7a so that the rotary switch 8 can be turned by hand by knob 7c. Knob 7c is on spindle 7b which runs through the centre of hollow motor shaft 9 and clutch 12 (see Fig. 4). Clutch 12 comprises a member 12a fast on spindle 7b and a member 19 slidable on spindle 7b and permanently keyed to the hollow output shaft 11a from the gear. Member 19 is moved by projections 17 on the end of a bifurcated lever 15 pivoted at 16 and connected to the end of push rod 13 carrying button 13b. When button 13b is depressed, lever 15 pivots about 16 and slides member 19 along the shaft out of engagement with member 12a. Member 19 is normally biased into engagement with member 12a by a spring 13a on push rod 13.

Abstract: 664,092. Photo-electric control of tracking apparatus. SPERRY CORPORATION. May 11, 1949 [May 26, 1948], No. 12568/49. Class 40 (iii). [Also in Group XXXV] An object, such as a star or an aeroplane in a bright sky, which radiates more or less energy than its background is automatically tracked by a telescope. In one arrangement, Fig. 2, a rotary shutter 28, driven by a constant-speed motor 31, divides the image field in two so that when the disc of light 38 from, e.g., a star is not central in the field, as shown in Fig. 3A, the photo-cell 35 will receive more light than when the shutter is turned through 180 degrees, and thereby provide an alternating output. The amplified photo-cell output is compared in phase-sensitive amplifiers 62, 63, with referencevoltages from a two-phase generator 46 driven from the shutter, to control up-down, and leftright tracking servomotors 18, 19. When the telescope is correctly tracking a circular image the photo-cell output will be unmodulated. To track a dark object on a light background, the error signals are reversed. In an alternative arrangement, Fig. 5, a reversion prism 51 is rotated about the focal axis 17 by a constantspeed motor 52, causing the image to rotate (at twice the prism speed) before it reaches a splitting prism 54 reflecting on to two photocells 55, 56. The cells are connected to a push-pull amplifier, and the output is compared with reference voltages from a two-phase generator 57 as before.

Filed: 1944-07-03
Abstract: 582,595. Grinding-apparatus. CARTNER, J., and DAVIES, R. July 3, 1944, No. 12656. [Class 60] In the grinding of articles, for example, dies, of irregular form, the article is fixed in relation to a cam having a profile parallel to that required in the article, the cam being gyrated whilst maintained in contact with an abutment having its cam contacting face adjustable in relation to the axis of the grinding-wheel, the cam being gyrated in a plane at right angles to the grinding-wheel axis. For the grinding of an external or internal workpiece by the use of an internal cam, a cam plate 10, Figs. 1 and 3, is employed with parallel internal and external cam contours 11, 12, the plate resting freely on the worktable 13 and the grinding-wheel 14 being mounted on an axis at right angles to the table. The contour 11 is engaged by a follower roller 15 having a conical bore 16 in which is the conical head 17 of a spindle 18 coaxial with the wheel 14, and the cam is driven by a friction roller 22 engaging the external surface of the cam ; by axial adjustment of the spindle 18, the roller 15 and the cam 10 are displaced horizontally, the roller 22 moving correspondingly so that the work-piece is moved to or from the grinding-wheel. The roller 22 is carried by an axle 23 mounted in one end of a lever 25 pivoted to the table 13 at 26 and the axle 23 is driven by chain gearing 30-32; a hole 34 in the lever receives a spring or weighted cable to press the roller 22 against the cam 10. On the cam are pillars 35 carrying a plate 36 provided with tapped holes 37 to receive bolts 38 for securing the work-piece 39, spaced by collars 42, to the plate 36. In operation, the cam 10 is gyrated by the rotation of the roller 22, the work-piece 39 thus being moved correspondingly past the grinding-wheel 14, cut being applied by adjustment of the spindle 18, which is screwed to engage an internally threaded sleeve 44 secured to the table 13 and rotated by a graduated hand-wheel 43. An external profile also may be ground, using the external cam 12. In a modification the axis of the grinding- wheel is horizontal, the wheel being mounted on a slide 77, Fig. 5, adjustable by rack gearing 81-83, and the cam 10 being secured by bolts 35 to a face-plate 60 mounted on a spindle 61 ; the work-piece 39 is secured by bolts &c. 42 to a second face-plate 64 also mounted on the spindle 61. The spindle is carried at one end of a balanced lever 62 pivoted on a carriage movable on rails at right-angles to the axis of the grinding-wheel, and the cam is rotated by a friction roller 22 driven by a motor 75 and carried by one end of a pivoted arm 71. The follower roller 15 is adjusted by the coned end of the spindle 18 which engages a nut 44a and is provided with a hand-wheel 43a. The master cam and work may be mounted on a fixed bearing and the grinding-wheel head and adjusting spindle with the follower rigidly connected to move as a unit.
