Title: Device for compensating for grinding wheel wear in a grinding machine
Inventor: GOLDBERG ISAAK MIRONOVICH
IPC: B24B49/04
Filed: 1969-03-17
Abstract: 1,268,451. Grinding. GOSUDARSTVENNY PROEKTNO - TEKHNOLOGICHESKY I EXPERIMENTALNY INSTITUT "ORGSTANKINPROM", and MOSKOVSKY IN- .STRUMENTALNY ZAVOD "KALIBR". 17 March, 1969, No. 2834/69. Heading B3D. [Also in Division G4] A device to compensate for grinding wheel wear in a grinding machine comprises an actuating mechanism 2 for moving a grinding wheel relative to a workpiece being machined, and a measuring mechanism 1 for measuring a workpiece that has already been machined, the mechanism 1 comprising a casing 3 for locating the workpiece being measured, and a measuring probe 9. The probe is resiliently mounted in a base 6 which is resiliently mounted in the casing 3 for movement relative to the casing in the direction of the workpiece being measured, and the base is operatively associated with a pusher 21 adapted to cause the base and measuring probe to move towards the workpiece being measured. An output unit 12 includes resilient means, separate from the resilient mounting of the measuring probe 9, for resiliently mounting the unit 12 between the base 6 and probe 9 for transmitting a signal to the actuating mechanism 2 to move the grinding wheel. The signal is produced by relative movement of the base 6 and probe 9 after the probe has contacted the workpiece being measured. In the device described the probe 9 is supported by elastic diaphragms 7, 8 in the base 6, which is itself supported by elastic diaphragms 4, 5 in the casing 3. The probe 9 is linked by flat springs 13, 14 to a flange 11 of the base 6, each spring carrying an electrical contact 15, 16. The pusher 21 is a wedge. The actuating mechanism includes a ratchet wheel 30 rotation of which causes adjustment of the grinding wheel. In operation a machined workpiece 20 is placed on measuring bases 18, 19 and the pusher 21 is slid by an hydraulic cylinder 23 to cause the base 6 and probe 9 to move towards the workpiece 20, thus deforming diaphragms 4, 5. When the probe contacts the workpiece the base 6 is moved relative to the probe to deform diaphragms 7, 8 and to bend springs 13, 14 until the contacts 15, 16 close. At this moment movement of the pusher 21 is stopped so that an electrical contact piece 26 moved therewith is in contact with one of a series of contact pieces 27 determined by the size of the workpiece 20. An hydraulic cylinder 35 is then operated to cause a lever 31 to rotate the wheel 30 to adjust the grinding wheel and at the same time to move an electrical contact piece 32 over a series of contact pieces 33 each connected to one of the pieces 27. When the piece 32 reaches the piece 33 corresponding to the piece 27 contacted by the piece 26 a circuit is made which actuates a relay 39. This sends a control signal to electromagnets 40, 41 which reverse valves 42, 43 so that the pusher 21 and lever 31 are returned to their initial positions leaving the wheel 30 in its adjusted position.

Filed: 1942-03-04
Abstract: 556,043. Uniting by fusion. HOWELL, N. March 4, 1942, Nos. 2842 and 7460. [Class 83 (iv)] An oxy-gas metal-cutting machine has its torch traversed by energy previously stored in a device by manually displacing said torch, the speed of traverse being determined by the rate of release of the stored energy. The energy may be stored by lifting a weight 5 which is connected to a piston in a cylinder 3 by a hollow rod 6 and to a smaller weight 10 by a chain 4 passing around a wheel 8 on the rotary torch carrier 2. The bottom of the cylinder 3 is connected to a reservoir 11 through a non-return inlet valve 12 and through a valve 13 which car be adjusted to regulate the flow of fluid from the cylinder and nence the speed ot traverse of the torch. In a modification the piston is connected to a rack engaged by a pinion 16 on a shaft 17, Fig. 2, which carries a drum 19 and weight 20 at one end and at the other a pinion 21 engaging pinions 22, either of which can be secured to the carrier 2. The head 24 may be angularly adjustable about the axis of the shaft 17. In other modifications the torch is moved along a straight line. Provisional Specification 2842/42 describes the use of compressible gas to supply the necessary energy which has been stored in it by a previous movement of the torch or by a compressor and an arrangement in which a piston actuated rack bar operates a pinion and endless chain, to either flight of which a slide, carrying the torch, may be clamped.

Abstract: 928,446. Making cartons from blanks. PEMBROKE CARTON & PRINTING CO. Ltd. Dec. 23, 1960 [Feb. 3, 1960], No. 3913/60. Class 18. [Also in Group XXIX] A machine of the die and plunger type for forming cartons from blanks, in which double side walls are folded over to enclose flaps on other walls to hold the carton erect, has the folding means 93 intermittently operated by the movement of the plunger. Blanks inserted into the machine along a platform 63, are pressed into a die 51 by a plunger 41 to bend up the sides of the carton at 90 degrees to the base. The plunger is driven downwards by a pneumatic motor 28 forcing sprung jaw members 83 back into recesses 61. At the bottom of the plunger downstroke the jaw members 83 spring back to grip the partially formed carton; the plunger 41, suitably grooved to avoid the jaw members 83, then withdraws. As the plunger 41 is withdrawn from the die 51 pivoted folding members 93 swing inwards to fold over the double side walls of the carton. The members 93 are turned, through chain and sprocket means, by a lever 100 which turns under the interaction of rollers 101 with a cam surface 102. The rollers 101 engage the surface 102 at the end of the withdrawal stroke and beginning of the downstroke only, consequently imparting an intermittent motion to the members 93. During the remainder of the motion the rollers 101 engage the sides of rods 22 on which the plunger assembly is mounted. The rods 22 slide in bearings 16, 17 and are driven by the motor 28 whose motion is controlled by limit valves 20, 37 in conjunction with a pneumatic relay valve (see Group XXIX). The die 51 is removable by releasing screws 55 and the plunger 41 by removing screws 40 to enable these to be replaced by members of different dimensions and thus enable cartons of different sizes to be dealt with.

A machine for applying sealing compound to the interior of receptacle, e.g. crown, caps comprises a transfer mechanism having two pairs of gripper members 20 supported on a carriage 11 which is reciprocated so as to supply the caps, in succession, to a chuck 7 rotatable below a nozzle 41 for applying the compound. The caps are fed from a cap-making machine 30 via a shoot 2 to a retainer device comprising a lower plate 3 spring-urged upwards towards a fixed top plate 6. The carriage 11 has two side arms 18 with holes 19 in which the grippers 20 are slidably mounted, the members 20 being spring-urged into contact with slide members 25 pivoted at 26 and interconnected by links 27 and a lever 28 so that they hinge inwards together thereby pushing each pair of the grippers 20 against caps between them. The slide members 25 are operated through link and rocker arm mechanism and a cam 32 in a shaft driven by a motor 31, a further cam 14 on the said shaft reciprocating the carriage 11, the arrangement being that the grippers 20 are moved inwards when the carriage 11 is in its rear position and remain gripping the caps as the carriage moves forward. When the rear pair of members 20 is in line with the chuck 7 the cam 32 allows the slide members 25 to move outwards and so release the caps, the front cap being released on to a conveyer belt 37 and the rear cap on to the chuck 7. The nozzle 41 may be controlled by a solenoid, automatically operated by micro-switches 42 actuated by a cam 43, and is mounted on a carriage 44 pivoted at 45 to enable the nozzle to be swung away from the chuck 7. Adjustment means for the nozzle may be provided. The chuck 7 has holes 10 enabling each cap to be held in position by suction, and is caused to rotate by gearing from the motor 31, up and down movement being imparted by a cam 8 also driven by the motor 31. Switch means are provided to ensure that discharge of compound from the nozzle only takes place at the correct times. The caps may be fed to the shoot 2 from a hopper. Specifications 675,569, 807,074 and 884,126 are referred to.
