Title: Improvements in and relating to vibration transmitting devices
IPC: G10K13/00
Filed: 1923-11-07
Abstract: 228,971. Grissinger, E. Nov. 7, 1923. Cases with internal horns; soundboxes, arranging and supporting.-In a cabinet gramophone the sound projector is constructed so that the wave beam is first flared in one dimension and then flared in a dimension at rightangles thereto, the general shape being shown in Figs. 1 and 2. The tone-arm 9 is of uniform diameter expanding slightly at the standard 14, which is adjacent the same face of the cabinet as the outlet. The conduit 10 widens in one direction as shown in Fig. 2, but preferably decreases slightly in the other direction, Fig. 1. It is preferably nearly straight, but may bend to 90‹ or more in the direction of its thinness. It opens. through a slot 15 into a reflector 11, composed of two walls 24, 25 at an angle between 80‹ and 105‹, which discharges into an outward projection in which the beam expands vertically. The angle between the walls 26, 27 is less than 90‹. The throat g, h is narrower than the slot 15. The conduit 10 is formed of sheet brass secured to a square bushing 16, the large flat sides being reinforced by channel bars 19, 20, 21 clamped by cross bars 22, 23. The reflector 11 and the walls 26, 27 are of wood. The vibratory areas of the walls of the conduit 10 or the entire conduit may be embedded in plaster of paris or concrete, or the entire conduit and projector may be an iron casting, the channel bars 19, 20, 21 being formed as ribs. The walls of the end portion of the projector may be parallel or may canverge slightly. In a modification, Fig. 6, the walls of the whole of the sound projector are formed of wood, the interior surfaces of which are smooth, stained, and polished. Vibration of the thinner portion of the wall 10b is prevented by piers 10e of wood glued between the walls 10b, 10a which are drawn together by screws 10g. The sound-box is arranged on the right of the tonearm with the stylus trailing towards the vertical axis of the tone-arm. The tone-arm 9 is bent through' a right-angle at its extremity for the attachment of the sound-box 5, Fig. 3, but may be bent so as to bring the vertical plane of the needle into the same plane as the vertical pivotal axis of the tone-arm. The sound-box 5 is secured to a tube 33' which is attached to the inner ring member 33 of a roller bearing. A spring 36 engages a projection 37 to retain the sound-box in the uppermost position. The weight of the projection 37 and housing 38 may be adjusted to cause the sound-box to bear in desired degree on the record. An adjustable weight may be screwthreaded on a rod projecting above and beyond the stylus for the same purpose.

Title: Gear box
IPC: E06C5/16
Filed: 1947-10-28
Abstract: 652,380. Change-speed and reverse gear ; friction clutches. BURG, G. VAN DEN. Oct. 28, 1947, No. 28731. Convention date, Nov. 6, 1946. [Class 80(ii)] A gear box for driving the various shafts of a variable-inclination telescopic ladder, with or without change of speed-ratio, is selectively controlled by clutch-units, e.g. 37, 39, which are grouped in an upper casing 7 on separate parallel driven shafts 29, 40, 41, around a central vertical driving shaft 11a and are removable as complete units in the axial direction. The gear is mounted on a turntable 3 rotatable on the frame 2 of a vehicle, power being supplied to central vertical input shaft 11, connected by bevels with the aligned geardriving shaft 11a, and driven by an enginedriven horizontal shaft 9, Fig. 2. The input shaft 11 turns the turntable 3 in either direction through a bevel-driven horizontal shaft 13, Fig. 1, forward-reverse clutches 19, 20, worms 17, 18, and a worm-wheel 16 integral with a pinion 15 engaging a stationary ring of teeth 14 on the fixed mounting plate 1. A second bevel driven horizontal shaft 12, aligned with 13, drives plumbing gear, not shown. This turning and plumbing gear may be omitted. The driving shaft 11a of the change-speed carries fast pinions 24, 25 (or sprocketwheels) constantly meshing pairs of wheels, e.g. 26, 27, each freely mounted on their respective driven shaft 29 and clutched selectively thereto by admitting fluid-pressure to one or other side of spring-released double cone clutches 28, 37. The shaft 29 drives through bevel and spur gears 42, 44, a winch 46 for the extension of the ladder which can thus be driven at two speeds in the same direction. The second parallel driven shaft 40 carries a double clutch unit 39 and gears identical with the first, 29, and drives, through similar bevel and spur gears 47, 52 and a further bevel 54, the usual elevating and depressing screw-shaft 56 of the ladder, and since this shaft requires a power drive in both directions, there is a third parallel driven shaft 41 carrying an identical double clutch-unit and driving the spur-gear 52 reversely through an opposite bevel 49, to provide two reverse speeds in addition to the two forward speeds by the shaft 40. The vertical driven shafts 29, 40, 41, are each supported in the gear casing by an upper bearing in a cover-plate 62 and! a lower bearing-bush 63, held in the casing by a set-screw 64, release of which latter and removal of the cover plate, permits the entire shaft unit, including the double friction clutch with its associated gear-wheels, the lower bearing-bush 63 and the bevel 42, to be withdrawn axially upwards from the casing. The upper gear-casing 7 may also be removed as a complete unit from the lower casing 6. Where speed-changes are not required the double-clutch units 37 &c. may be replaced by single clutch units.
