Patent GB-255174-A (GB)
Title: Improvements in acoustic diaphragms
IPC: H04R7/12
Filed: 1925-04-27
Abstract: 255,174. Walker, D. F. April 27, 1925. Diaphragms.-Relates to acoustic diaphragms, applicable to instruments, such as telephonic loud-speakers and microphones, sound-recording and reproducing machines, and musical instruments. According to the invention, the diaphragm is built up of a number of separate rigid sections united at their edges so that adjoining sections lie in different planes. In the construction shown, a large diaphragm, suitable for a loud-speaker, is formed of triangular panels 1 joined together so that they radiate from a central bush 1, the edges 4 of the panels being disposed in a common plane to which the edges 2 are inclined. Thus the panels form V-sectionjed channels. The spaces between the small sides 5 of the triangles 1 are filled in by sector-shaped smaller panels 6, the edges 7 of which fit against a peripheral support 8. The panels 1, 6 are preferably made of thin wood or parchment, stiffly supported on stouter wooden frames, and the construction of the diaphragm may be such that all the veneer surfaces are on one side and the framework on the other. Alternatively, stiff flat panels of wood, celluloid, or ebonite, &c., may be used. The points of the panels at the periphery of the diaphragm are sunk into shallow holes in the supporting ring 8, where they are secured by a suitable, medium such as a cellulose cement. The adjacent edges of the panels are also cemented as shown at 9, Figs. 11 and 12, and the meeting edges on the veneered side are covered by narrow strips of veneer 10. The cementing is carried out whilst the sections of the diaphragm are held together by means of a jig or cramp, the points of the panels which adjoin the centre being temporarily supported by a rubber bush. This is subsequently replaced by the flanged wooden bush 11, cemented and held in place by a ring.. The bush is connected to the Electromagnetic armature or the equivalent. The panels may be so disposed that the long edges 2 are in the plane of the peripheral ring 8. Instead of constructing the diaphragm with radial corrugations as shown, it may be built of quadrilateral and triangular sections, forming annular corrugations. In the application to musical instruments, vibratory or resonant parts thereof are connected to the diaphragm through a stylus or otherwise. For example, in a violin the diaphragm may be mounted on the body of the instrument and its centre connected by a vibratory post to the bridge over which the strings are stretched.

Title: Improvements in or relating to lathe and like tailstocks
IPC: B23B23/00
Filed: 1956-04-10
Abstract: 806,389. Lathe-details. JEANNERET, J. L. April 10, 1956 [April 14, 1955], No. 10919/56. Class 83 (3). A high-speed feeding-device for a lathe or like tailstock comprises a plunger slidably carried in a casing rigid with the tailstock and adapted to produce a quick motion of the normal screw-control movement of the tailstock-sleeve, the plunger being moved by a roller &c. connected to a crank and rotatable by a handle mounted on an axis perpendicular to the tailstock-axis, the roller engaging a transversegroove in the plunger. A housing 1, Fig. 2, carrying the quick-action device, is secured to the rear of the tailstock-housing 2, and the normal screw 9 moving the centre-sleeve 3 is controlled by the hand wheel 10. A hand-lever 8 is secured to a short spindle at right-angles to the tailstock-axis and rotatable in bearings 23, 24 in the housing 1. This spindle has a crank 11 at its inner-end carrying a roller 12 which engages a transverse-slot in the underside of a longitudinally-slidable member 17, Fig. 4, arranged within the casing 1 and bored to allow the operating spindle of the slow-motion adjusting-handle 10 to pass therethrough. The member 17 transmits quick-action movement to the tailstock-centre through collars 27, 28, 18, and a spring 16 which allows for expansion. The slow-motion feed may be locked by screwing-up a set-screw 19 to engage a collar 20, which is prevented from rotation by a pin 21 slidable in a hole in the casing 1. Alternatively, the quick-motion device may be locked by a set-screw 25 when the tailstock is used for drilling operations. A pin 14 fixed to the housing, Fig. 4, moves relatively to a slot 15 adjacent the handle 8, and limits the movement of the latter.
