687,319. Lathe details. WERKZEUGMASCHINEN-FABRIK GILDEMEISTER & CO., AKT.-GES. May 1, 1951 [May 2, 1950], No. 10210/51. Class 83 (iii). [Also in Group XXV] A lathe frame has curved walls extending convexly downwardly from an integral headstock towards the base to provide a bowlshaped cross-section, the walls consisting of inner and outer members connected at the upper ends to give a smooth inverted U-form upon which guide tracks are located, the inner walls extending vertically downwards beneath the guide tracks so as to leave between them a substantial space for the passage and reception of cuttings. The frame 1 which includes the integral headstock 2, Fig. 1, is of smooth exterior form, closed at the bottom, which rests directly on the floor. Guideways 6a, 6b, Fig. 3, are provided on the upper parts of double wall members which are of inverted U-form. The rear member is cut-away to provide a large space 9 for cuttings and a plate 12 over the closed bottom forms a receptacle 11 for draining coolant. A recessed portion 15 with passages 16, 17 allows coolant running down the front of the machine to drain into the part 11. The front of the frame is curved inwardly towards the bottom to provide clearance for the operator's feet. Cut-away portions 21 provide tongues 22 which do not extend beyond the smooth surface and provide means for attaching lifting tackle. A gap is provided at the end opposite the headstock for removing cuttings and at the headstock end a large door 3, merging with the bed form, covers the driving mechanism. This door has hinges (see Group XXV), which enable the door to be moved firstly in a rectilinear direction away from its opening prior to rotating it completely to one side. The door is lined up in the closed position by dowels and fastened by a latch member (see Group XXV), the head of which fits flush with the frame when the door is locked. Electric wires and further driving mechanism are housed within the space 14 in the front doublewalled member. |
