Title: Spinning and smoothing lathe
IPC: B21D22/18
Filed: 1961-02-20
Abstract: 906,287. Spinning. LEIFELD, T. F., [trading as LEIFELD & CO. WERKZEUG-UND MASCHINENFABRIK.]. Feb. 20, 1961 [Feb. 18, 1960], No. 6127/61. Class 83 (4). A sheet metal spinning and smoothing lathe is characterized by a tracing device mounted on the tool slide whereby a tracer controlling the repeated spinning movements of the spinning tool along the rotating workpiece is guided at each working stroke by one template of a compound template which is of a slightly different shape than the next template of said compound template. The workpiece, e.g. a cupped blank on which it is desired to form a neck portion 11, is clamped on the chuck of the lathe. The bed of the lathe carries a template 14 on supports 13 and directly beneath the template 14 a reciprocable template 16. The fixed template 14 is curved to the final shape intended for the workpiece and the movable template 16 has a straight edge 17. The template 16 is guided on rods 18 and reciprocated by an hydraulic cylinder 23. A roller 26 on an arm 27 is adapted to roll along both templates 14 and 16 and controls the movement of the spinning roller 28. In operation, the straight edge template 16 has the purpose of permitting the tracer to move only along a portion of the template 14 on each working stroke such portion being increased after each stroke by retraction of the templet 16 until the full templet 14 is being used and the workpiece is shaped to its final form. The intermittent movement of the templet 16 is controlled by switches 30, 31 on the tracer 27 which engage stop members 34, 35 on the machine base and switches 32, 33 actuated by stops 36, 37 on the guide rods 18. These switches act on electromagnetic valve controlling the hydraulic cylinder 23. The spinning is carried out on both forward and return strokes of the roller. The stop member on the parallel guides for the last working stroke with a reduced infeed is adapted to change the rotary speed of the workpiece for smoothing the surface of the workpiece. In another embodiment the compound template consists of a set of superimposed templates 40 clamped together on a frame 43. A spinning roller 28 and a tracer 45 are mounted on the tool slide the tracer being vertically adjustable on a support 46 by an arrangement similar to that used for moving the templet 16 in the previous embodiment so that the workpiece is shaped in a series of progressive steps which are carried out automatically.

Abstract: 312,337. Gianolio, G. May 25, 1928, [Convention date]. Liquid - level pressure gauges.-A gauge adapted to indicate liquid levels at a distance comprises two tubes which transmit the pressure from the bottom of the liquid and from the space above the liquid respectively to an indicator comprising an inverted U-tube gauge. Fig. 2 shows a device comprising two tubes VS, VD; the top of the tube VS is connected to a tube K extending into a depression r in the bottom of the tank R, and the top of the tube VD is connected by a pipe z to the top of the tank. The indicator consists of the tubes CS, CD connected by the bridge part F, and an adiacent scale 70. A liquid G fills the parts VS, VD, the connecting pipes s, d and parts of the tubes OS, CD, and a coloured liquid 0 of less density fills the bridge part F. A rise in the liquid level B alters the position of the levels in the tubes CS, CD. Corrections for various errors may be made by means of a receptacle connected to the pipe s, near the transmitter or near the indicator, by making the pipe s larger than the pipe d, or by making an enlargement in the pipe s. The transmitter VS, VD may be placed in an inclined position in tanks. Valves 71, 72 connected by linkwork 73 are used for charging the tanks and manipulating the charges. These may be replaced by a spring- loaded sliding piston valve. The depression r may be replaced by a small saucer, and the leg of the siphon K entering it may be surrounded by cotton waste or the like.
