Patent GB-1277316-A (GB)
Title: Machine tool
Inventor: GRAZIANO WILMER
IPC: B23Q3/155
Filed: 1970-06-18
Abstract: 1277316 Tool changers; machine tool details A GRAZIANO and W GRAZIANO [trading as GRAZIANO & CSNC] 18 June 1970 [21 June 1969] 29525/70 Headings B3B and B3T A machine tool, e.g. a lathe 10, comprises a tool holder turret 16 movable longitudinally by means of a first saddle 13 on which is transversely movable, a second saddle 15, and a tool holder magazine 19 suspended above the lathe. The turret 16 is rotatable to carry a tool from a replacing position to an operative position and vice-versa and a magazine 19 is rotatably supported by a first slide movable transversely on guides 22 which are carried by a second slide 23 movable on guides 24. The machine tool comprises means for moving the magazine to a tool charge position relative to the turret at all positions of the latter, means for rotating said turret and clamping a first tool at the operative position and releasing a second tool at the replacing position, and means for moving a tool from the turret to the magazine and vice-versa. The magazine 19, in the embodiment described, is connected to the turret 16 by means of a pin extension (76) (Fig. 3, not shown) so that movement of the turret also moves the magazine. Alternatively the magazine 19 may be moved by independent means under automatic programme control, which may provide for bringing the magazine to one end of the machine for re-stocking the magazine during a machining operation and then repositioning the magazine over the turret 16 when a tool change is required. The magazine includes an independent electric motor (60) for indexing itself and an independent motor (74) for raising and lowering a feed device, e.g. a drive nut or a feed screw, for moving a tool holder 18 between the turret and magazine. Alternatively a fluid pressure ram may move the tool holder 18. The turret 16 is indexed 180 degrees by a fluid pressure actuated rack and pinion drive (46) (44) after initially raising the turret by fluid pressure means to release conical engaging surfaces (43). As the turret rotates cams (53), (55) actuate tierods to clamp or release the tool holders.

J., 223, Cromwell Road, Earl's Court, all in London. Oct. 8, 1930, No. 30085. [Class 97 (ii).] An optical viewing instrument is combined with a magnetic compass card which is normally horizontal and adapted to be returned to that position when moved therefrom by inclination of the instrument and is provided with an annular rim or band having an externally marked compass scale adapted to move past a prism for reflecting a bearing indication into the image field. In the form shown, one member 2a of a pair of binoculars is provided with a vertical tube 1 carrying at its upper end a detachable ring 16 in which pivots a casing 14 on a solid trunnion 15 and a hollow trunnion 15a. The casing 14 contains a pivoted magnet 12 carrying a cylindrical card 11 the curved surface of which is marked with a horizontal line 19 and with vertical compass graduations 11a. A graduated knurled collar 22 enables the casing 14 to be turned into the horizontal if it is displaced therefrom. The indications of the card 11 and a spirit level 21 may be illuminated by daylight or electric light reflected on to them by a prism (not shown) and after passing through the window 18 in the hollow trunnion 15a are reflected by the prism 3 down the tube 1 to a prism which reflects them at 6 into the image plane 9 of the member 2a of the binoculars where they are viewed simultaneously with the object. When the binoculars are directed towards an object and the casing 14 turned into the horizontal, the magnetic bearing is indicated by the image of the graduations 11a read against a fixed vertical wire in the image field and the inclination by the angle to the vertical wire of the image of the line 19 as read against an angle scale in the image field. The casing 14, instead of being mounted in the ring 16, may be rotatably mounted in a bearing provided in the tube 1. A separate inclinometer comprising a graduated pendulum disc rotatable in a vertical plane and arranged so that its highest point almost touches the compass card may be provided, the indications of the inclinometer and compass being simultaneously reflected into the image plane. According to the Provisional Specification the readings of a detachable range-finder may be reflected into the image field.

Abstract: 1,117,870. Grinding; milling. CENTRE DE RECHERCHES SCIENTIFIQUES ET TECHNIQUES DE L'INDUSTRIE DES FABRICATIONS METALLIQUES, and M. SZWARCMAN. 6 July, 1966 [6 July, 1965; 28 June, 1966], No. 30389/66. Headings B3B, B3D and B3K. A method of machining a component 3 having one or more elements 9 made from a material permeable to a pressurized gas comprises passing pressurized gas through the element or elements simultaneously with the machining operation. As described, the component 3 consists of a metallic body which is mounted on the magnetic plate of a grinding or milling machine and is formed with a plurality of recesses 4. The elements 9 of porous material are secured at their circumferences in the recesses which are connected by a passage 5 and flow meter 8 to a source 6 of pressurized air. The air pressure deforms the elements so that they bulge outwardly and the machining operation reduces the bulge to a flat surface so that when the air pressure is cut off the outer face of the element is concave. The component 1 may consist of a machine tool carriage which is to be carried on a slide, the method ensuring that the elements do not carry the weight of the component. The material of the elements may be selected to have a greater permeability than required after machining to compensate for clogging of the material caused by the machining.
