Filed: 1968-05-15
Abstract: 1,189,923. Gauging toothed gears. W. FERD KLINGELNBERG SOHNE G.m.b.H. May 15, 1968 [Aug. 4, 1967], No. 23104/68. Addition to 1,189, 922. Heading G1M. The Parent Specification describes a testing apparatus comprising a slide 27 which when moved across a bed 10 by rotating a crank handle rotates a test gear 1 and at the same time a cylinder 25 mounted in bearing plates fixed to the bed. A shaft 20 carries a radially adjustable feeler head 17 and feeler 18 is keyed to rotate with the cylinder 25 but not move axially within the cylinder. In this Specification however the shaft 20 is made to be axially movable within the cylinder by arranging that an adjustable guide 94 moving laterally with the slide 27 engages a peg 97 in the bearing housing 96 thus giving the housing 96 and the shaft 20 axial movement. In Fig. 2 (not shown) the axial movement of 20 combined with its rotation gives a helical movement to the feeler mounted on the end of the shaft, and in Fig. 3 (not shown) the feeler head is mounted on one arm of a Z-shaped lever (100) pivoted to a stirrup (101), (102), fixed on the cylinder 25. The other arm of the Z-shaped lever is slotted and in the slot is a vertical bar (103) fixed by a bracket (104) to the end of the shaft 20. Rotation of the cylinder 25 and axial movement of the shaft combine to give the feeler 18 a spherical movement (105) about the apex point of the level gear being tested. In Fig. 4 (not shown) for testing spiral level gears, the cylinder 25 supports a stirrup (106) which in turn supports a slider (108) mounting a rotatably adjustable slotted disc (110). Pivoted across the slot is a bar (112) grinding a longitudinally slidable rod (113) mounting the feeler 18 at one end and provided with a roller (114) at its other end, the roller being pressed by a spring (115) against the axially movable collar ended shaft 20.

Title: Improvements relating to pneumatic gauging apparatus
IPC: G01L7/00
Filed: 1947-08-22
Abstract: 638,209. Pressure gauges; pneumatic gauging-apparatus. ETAVEX SOC. ANON. Aug. 22, 1947, No. 23301. Convention date, July 18. [Class 106 (ii)] [Also in Group XXXVIII] Pneumatic gauging apparatus, which can be used also for controlling the operations of a machine tool such as a lathe or grinding- machine, comprises a member 12 supplied with air at constant pressure, connected to a casing 17 in which is a differential pressure gauge comprising a circular diaphragm 29 clamped at its edge between two discs 24, 30. The discs are perforated at 27, 31, and shaped on the inside to support the diaphragm over its full area in the event of excessive air pressure. Air from the member 12 passes through a fixed orifice 15 into a chamber 18, and escapes to atmosphere through an orifice 19 controlled by a conical point 40. This point 40 forms part of a flange 45 which has screw-threaded engagement with a cap 20 of the casing 17. Air from the member 12 also passes through a fixed orifice 16 into a chamber 21, and escapes to atmosphere through a fixed orifice 22. The diaphragm 29 is connected by a rod 34 to an electric contact 35 which can be moved by the diaphragm to complete a circuit to a reversible motor 41, either through a contact' 37 or contact 38. A pinion 44 on the motor shaft meshes with gear teeth on the inside of the flange 45, whereby the orifice 19 can be varied by the motor. In use, a standard work-piece is placed on an adjustable support M, and adjusted towards the nozzle 22 so that the pressures in the chambers 18, 21 are the same, and the diaphragm therefore not deflected. A work-piece to be gauged is then placed on or moved over the support M ; if the distance between the nozzle 22 and the work-piece is under or over standard, 'the pressure in the chamber 21 will increase or decrease, respectively, the diaphragm 29 will be moved, and the motor 41 rotated to adjust the flow of air through the orifice 19 so that the pressure in the chamber 18 is the same as that in the chamber 21. A scale 48 on the flange 45 cooperates with a pointer 49 on the cap 20 to indicate the extent to which the dimension e of the work-piece departs from standard. In a modification, Fig. 3 (not shown), the flange carrying the conical point 40 is adjusted by hand to balance the pressures on the diaphragm; the latter closes contacts in lamp circuits to indicate increase or decrease in pressure in the chamber 21. The apparatus can be used on a machine tool, such as a grinding-machine, to indicate when the workpiece has been reduced to correct size, in which case the upper contact 37 is removed, and the setting arranged so that when the contacts 35, 38 are established, a relay device stops the machine.
