Title: Improvements in means for spinning metal
IPC: B21D22/16
Filed: 1933-08-02
Abstract: 424,884. Making hollow-ware. MIDLAND METAL SPINNING CO., Ltd., and WYER, J. M., Tower Works, Pelham Street, Wolverhampton. Aug. 2, 1933, No. 21684. [Classes 83 (ii), 83 (iii), and 83 (iv)] Spinning ; bending; beading ; lathes.- A machine for performing a spinning operation on a metal vessel, such as forming a neck on an aluminium vessel J, comprises a chuck H in which the work is rotated, and a carriage B movable transversely on a longitudinally traversable saddle C, the carriage B supporting means such as an external spinning tool S and an internal tool R to displace the material radially as they move longitudinally, in a straight line, the tools being automatically displaced radially after each longitudinal traverse. The movements of the slides are controlled by handles L, N and racks and pinions M, O, and are limited by cams V, W on the saddle the former of which abuts against a stop b to limit the longitudinal traverse and the latter of which is engaged by a member e on the carriage B. The cams are partially rotated after each traverse of the tools so that the strokes are successively shorter in length and at a smaller radius as indicated in Fig. 13, the cams being formed to impart the desired shape to the neck. The cams are secured for rotation to the centre member of a free-wheel device k permitting rotation in one direction only, teeth on the external part of the wheel k meshing with a roller-rack on a slide p, slidable in the saddle C, a stop u on which engages a finger a<1> at the end of the rearward movement of the saddle to move the slide up to a stop r against a spring and rotate the cams. The wheel is held by a spring-pressed plunger m engaging a wheel after each movement. Before the last stroke the finger a<1> is caused to swing upwardly so that the cams are not actuated on the return stroke. The upward movement is effected by a roller d<1> on a vertically movable plunger f<1> which is allowed to move upwardly under the action of a spring when a lever j<1> is swung clear of the end of it, this occurring when a nose m<1> on the lever enters a recess n<1> in the surface of a member p<1> rotatable with the cams and against which it is urged by a plunger q<1>. In this position the tool-turret A is released by a handle E and rotated to bring tools a<2>, b<2> into action, which complete the shaping of the neck. The third set of tools comprises a trimming-tool c<2>, a flanging tool d<2>, and a tool e<2> for curling the flanged edge. The saddle is then retracted to bring the stop u against a second stop to return the cams to their initial positions, the other parts of the machine being reset. The cams may be replaced by a series of projections. The carriage B and saddle C may be moved by cams instead of by hand levers.

Abstract: 157,502. Harrap, W. O. Sept. 5, 1919. Registering webs. - Relates to devices for guiding cloth &c. to stentering, finishing, dyeing, drying, and other machines wherein angularly adjustable pairs of edgenipping rollers are arranged to draw out the fabric as it is fed, the nip of the rollers being controlled automatically by mechanical means. The movable roller a', Fig. 2, is carried by a cradle b<4> fulcrumed at b<3> to the bracket b supporting the other roller a, and is acted upon by a plunger or sliding device c influenced by a spring-pressed pivoted loading-lever g. The other end of this is forced by the spring g<3> against a thrust collar f<3> adjacent to a clutch half f<2>, which is slidably mounted on a driven shaft e and normallv engages the other clutch half f<1> rigid on the shaft e. A cam-groove f<4> in the clutch half f<2> engages a bowl h<2> on one end of a bell-crank lever b pivoted at h<1>, as shown in Fig. 5, so that the other end h' of the bell-crank normallv oscillates between the two positions shown in Fig. 6. If the fabric runs to one side, an arm j linked to a pivoted feeler i<2> engaging the edge of the fabric is thereby obtruded into the path of the end h<3> of the bell-crank lever h, which then disengages the sliding clutch half f<2>, thus releasing the pressure of the loading-lever g on the plunger c and releasing the nip between the rollers a, a<1>, until the fabric is caused to run central again by the nipping rollers at the opposite side. Figs. 5 and 6 also show additional means which may be provided for positively moving the obtruding arm j into and out of obtruding position, and means comprising a pivoted sector k formed with a curved recess k' terminating in shoulders k<2> and vibrated continuously by means of a spring- pressed lever k' engaging a cam k<5> on the shaft e. The obtruding arm j carries a double pawl member l pivoted thereto at l<1> and connected by a link m to a stud i<3> on the pivoted boss i of the feeler i<2>. When the latter is tilted by the fabric running out of centre the pawl member l is also tilted so that its right-hand pawl l<2> engages the right-hand shoulder k<2> of the vibrating sector k, which then moves the obtruding arm j into obtruding position. When the feeler moves back to its normal position the pawl member l is tilted in the reverse direction, and the arm j is moved positively out of obtruding position by the lefthand shoulder k<2> engaging the left-hand. pawl l<2>.

Filed: 1961-06-22
Abstract: 934,905. Space discharge devices. FERRANTI Ltd. June 20, 1962 [June 22, 1961], No. 22546/61. Class 38 (4). A high voltage controlled chopping means for, say, terminating a testing impulse applied to a transformer winding comprises a series stack of low voltage gaps 1-41 having a chain of parallel grading resistors 46 connected thereacross, at least one gap being a triggered gap, and each of the non-triggered gaps having a portion of perforated metal allowing ultraviolet radiation from a fixed gap to pass and trigger the next unfixed gap. The gaps comprise a hemisphere 1 and spheres 2-41 constructed from metallic gauze supported within, and connected to copper rings 42, the assembly being adjustably supported by non-conductive threaded rods 43. The spheres 2-4 are connected to the rings 42 through resistors which are also connected to triggering electrodes 49-51. The hemisphere 1 has a triggering electrode 48 connected to a delay line 52. When the impulse is applied across the transformer a pulse is applied to the delay line 52 which gives a delay equal to the impulse duration. The resistors 46 distribute the impulse across the stock in a desired relation which is insufficient to fire the gaps. The gaps may alternatively have a spacing progressively increased from the triggered end. When the pulse arrives at the triggering electrode 48 this gap is fired, shunting bottom resistor 46, thus setting off gaps 2-4. U-V radiation from gap 4 then passes to gap 5 causing this to fire also the subsequent gaps due to the redistribution of voltage. In another arrangement (Fig. 3, not shown), the stack is comprised of a number of insulating telescoping tubular units each having hemispheres mounted internally and resistors wound externally, any required number of units being assembled according to the voltage required.
