Title: Improvements relating to machines for grinding points on drills
IPC: B24B3/24
Filed: 1959-12-31
Abstract: 890,035. Grinding drills. BODDAERT, W. R. Nov. 25, 1960 [Dec. 31, 1959], No. 44357/59. Class 60. A machine for grinding the point of a drill 3 comprises a centring vice 6 and a chuck 4 which are adapted to grip the lands of the drill and are mounted on a block 7 pivotal about an axis X disposed in the plane Z of the face of a grinding wheel 2, means 12A for rotating the chuck about the axis of the drill, means 15 for adjusting the position of the chuck longitudinally of the axis of the drill, a member 22 by which the position of the drill can be set in the chuck, and means 31 for dressing the face of the grinding wheel. The pivot block 7 is rotatably mounted in a member 8 on the end of a shaft 9 which is axially adjustable by a hand-wheel 1C to position the axis X of the block in the plane Z of the face of the grinding wheel. The block has a guide-way 17A for a block 17 which supports the chuck 4 in a gimbal 16A for movement about a pin 16 whereby the drill point can be supported on a rest 5 during a grinding operation or be presented to the setting device 22 which is adjustable by a screw 25; movement of the block 17 along the guide-way 17A determines the angle of the point of the drill. After positioning the point of the drill against the setting device, the drill is gripped in the chuck 4 by rotation of a nut 29 which presses jaws 26 against the lands of the drill. The drill is then moved on to the rest 5 and centred by jaws 6 movable by a screw 18 connected to the jaws by a slide 20, push rods 19 and levers, the jaws gripping the lands of the drill. Thereafter, the block 7 is rocked to move the point of the drill across the face of the grinding wheel. The drill is ground with two pairs of corresponding facets set at the backing-off and cutting angles, the backing-off angle being determined by a stop 7B in a recess 8A and the cutting angle being determined by an adjustable nut 11. The chuck 4 can be axially adjusted by rotation of a nut 15 and rotated through 180 degrees to a position determined by interengaging lugs by axially moving and then rotating a nut 12A. The pivot block 7 can be moved to a position wherein a diamond 31 carried therein can be traversed across the face of the grinding wheel, rotation of the handwheel 10 feeding the diamond and the pivot block towards the grinding wheel to maintain the axis X in the plane Z of the face of the grinding wheel. An inspection lamp 23 and a light 32 are provided to assist in adjusting the position of the drill. The machine can be adjusted to grind right and left-hand drills and assembly of the shaft 9 and handwheel 10 can be modified to receive a webthinning attachment.

As described, the workpiece consists of a slab 24 which initially rests on rollers 25, ... 28 and is fed past axially adjustable saws 20, 21, 22 to be cut into boards which are received on rollers 30, ... 34, the saws producing two boards (35, 36, Fig. 3) and waste pieces (37, 38). The guide device produces shadow lines (39, 40, 41, Fig. 2), which indicate to the operator the lines of cutting of the saws and both the saws and shadow lines are simultaneously adjustable so that the operator can produce the maximum sizes of boards. The device has a pair of uprights (43, 44, Figs. 7 and 8) which are positioned adjacent the saws 20, 21, 22 and carry triangular frames (49) between which extends a rail (53) supporting the light source (54). The source consists of a filament tube and a slotted panel so that an intense beam of light is directed downwardly and the frames (49) are vertically adjustable by means of screws (61). The uprights also carry, between the light source (54) and the path followed by the workpiece, arms (79, 85), arm (79) supporting pairs of guide rods (74, 75) and (86, 87), and arm (85) supporting pairs of guide rods (80, 81) and (92, 93), the rods being mounted in blocks secured to the arms. The shadow lines (39, 40, 41) are produced by wires (64, 65, 66) which extend under tension between pairs of blocks (67, 68, 90, 91) and (71, 72) slidable along the guide rods. The pairs of blocks associated with each wire are connected respectively to cables (101, 113, 122, Fig. 14) which are entrained about various pulleys on the arms (79, 85) and elsewhere on the machine and which, at one end, are connected to respective levers (112, 102, 121), and, at the other end, are tensioned by weight (111). Each lever is associated with a respective saw to axially move the saw so as to adjust its line of cut, the lever at the same time, by means of its cable, moving its wire so that the shadow formed thereby will indicate to the operator the line of cut that the saw will make. The arrangements of the cables about the pulleys is such that the wires always move parallel to themselves.

Title: Improvements relating to spit roasters
Inventor: BARKER HUGH PURSLOVE
IPC: A47J37/04
Filed: 1961-12-14
Abstract: 946,355. Basting devices. PARKINSON COWAN Ltd. Nov. 29, 1962 [Dec. 14, 1961], No. 44729/61. Heading A4D. A basting device for attachment to a rotatable spit 2 so as to rotate with it intermittently, comprises an arm 6 attached to a hub 4 clamped to the spit 2, and a scoop 7 at the other end capable of scooping up liquid in pan 3 and basting the article impaled on the spit. A plate 8, which has a weight 13 attached to it, has a keyhole slot 9 whose rectangular portion can fit over a similarly shaped portion of the hub 4 and a lug 11 engaging a slot 12 in the arm 6. When the spit has rotated so that the shorter side of the rectangular portion of the hub 4 is horizontal, Fig. 1, the weight 13 causes the rectangular part of the slot 9 to fit over the hub 4, the hub 4 then rotates with the spit 2 and thus lifts the scoop 7 to baste the article. When the weight 13 reaches a position below the spit 2 it causes the round part of the slot 9 to surround the hub 4 and thus the spit 2 rotates alone, and the scoop 7 swings down to the lowermost position under gravity and the cycle continues. Hence the article is basted from two sides. If the portion of the hub 4 is hexagonal more than two sides would be basted. Also, instead of a mechanical connection, a one-way clutch between the spit 2 and arm 6 could be used to carry the arm 6 upwards and let it rotate down under gravity.

Patent GB-449114-A (GB)
Abstract: 449,114. Controlling gas burners. VAILLANT, B., 5, Lenneperstrasse, Remscheid, Germany. May 22, 1935, No. 14982. [Class 135] A controlling arrangement for gas-heated water heaters of the kind in which two separate conduits 9, 11 lead to an ignition head 10, one of which leads from the actuating chamber of the main valve and is controlled at its outlet end by valve 12 actuated by a heat sensitive element subject to the heat of the pilot flame, has one or more manually actuated control members 3 in the two conduits arranged so that in the shut-off position the thermally operated valve is isolated and the two conduits connected with one another. In the form shown in the Figs. the control cock plug 3 has two through-way passages at right angles 8, 8<1>, and a longitudinal groove 6. To start the apparatus the cock 3 is turned so that the passage 8 connects the pipe 1 leading to the gas inlet to the preignition pipe 9. After the pilot burner has been ignited and the valve 12 opened by the expansion of the thermal element the plug 3 is turned so that the passage 8<1> connects the pipes 2 and 11. The pipe 2 leads from the chamber u beneath the actuating diaphragm of the main gas valve 13, as this chamber is fed through a restricted passage 13b, the escape of gas through the open valve 12 causes a reduction of pressure below the diaphragm so opening the main valve. If water is being supplied to the apparatus the gas valve 16 is also open, so that gas can now flow to the main burner where it is ignited by the pilot. When the cock 3 is turned to the shut-down position the groove 6 connects the pipes 1, 2 so equalizing the pressures on the two sides of the diaphragm and allowing the spring loading to close the main gas valve. In a modification the pipes 9, 11 are mounted on a rotatable member so that the ignition head may be moved towards the main burner and the appropriate change of supply pipes effected at the same time. In a further modification the control cock 3 and the rotatable ignition head are interconnected by a pin engaging a cam slot so as to be operable by a single handle.

Abstract: 1,166,378. Reel cases. COMDATA CORP. 9 Oct., 1967 [8 Feb., 1967], No. 45280/67. Heading B8P. [Also in Division E2] A tape reel container comprises upper and lower container members, an operating handle secured to the centre of the upper member and rotatable between first and second positions, a locking mechanism operated by the handle to lock the members together when the handle is in the first position and to allow separation when the handle is in the second position, a locking member resiliently biased to a locking position in which it locks the handle in the first position when the handle is moved thereto, the handle being incapable of being moved from its first to its second position without simultaneous manual operation of the locking member to move it out of the locking position. As illustrated the members 19, 17 are adapted to be secured together by balls 75 carried by the upper member which are urged by a cam 85 into engagement with a locking flange 93 on the lower member. The cam is carried by a rotatable operating member 77 and comprises grooves 89, 91, and flattened portions 87. When the operating member is in its releasing position the cam portions 87 are adjacent the balls (Fig. 10). Rotation of the operating member by its handle causes the grooves 89 to engage the balls and lock the container members together. Further rotation of the operating member into a slipping position with the grooves 91 engaging the balls is permitted by depression of an annular locking ring 103 against spring 97 so that the end portions 127 of the handle may pass over upstanding projections 111 on the ring. The ring is non-rotatable and movement of the operating member beyond its shipping position is prevented by lugs 115 which engage lugs 101 on the upper container member. The two container members are sealingly engaged by rings 53, 55 and 57 and the lower member comprises a substantially rectangular outer wall, a circular inner wall and a hub 49. Handles are provided by a continuous strap (41) (Fig. 1, not shown) e.g. of plastics tubing, which passes through recesses (31 and 35).

Abstract: 1,125,737. Automatic voltage control. MARCONI INSTRUMENTS Ltd. July 17, 1967 [Oct. 13 1966], No.45723/66. Heading G3R. A D. C. voltage stabilizer comprises an input source 1, 2, 3, 4; output terminals 10 connected across a storage capacitor 7; a series switched transistor 6 controlled in known manner by a monostable circuit A in dependence upon output voltage variations; and a triggering circuit B which actuates the monostable circuit A not at a constant frequency as in the usual manner but at a frequency controlled by the output voltage, the arrangement being such that the frequency decreases with decrease of output voltage and increases with increase of said voltage, whereby the transistor 6 is protected against damage which might otherwise occur, e. g. on switch-on or on overload, due to excessive charging current occasioned by abnormally low voltage across the capacitor 7. As shown, the circuit B includes transistors 21, 22 connected with capacitors 23, 24 to form a bi-stable circuit having an operating frequency determined by the emitter current of a further transistor 25 which emitter current is provided, in the condition of minimum frequency, by a fixed voltage source applied to terminal 27 and which is augmented, when the output voltage reaches a predetermined value, by current dependent upon the output voltage and derived by way of resistors 29 and a diode 28; a Zener diode 30, associated with the resistors 29 as shown, prevents the augmenting current exceeding a predetermined maximum value. Thus, when the voltage across the capacitor 7 is abnormally low the frequency of circuit B is at a pre-determined minimum, e. g. 400c/s, which is sufficiently low to protect transister 6; as capacitor 7 begins to charge and after the voltage across it reaches a certain value the emitter current of transistor 25 is increasingly augmented, and the frequency of circuit B increases accordingly until a maximum frequency, e. g. 9Kc/s, suitable for normal running is reached.
