Abstract: 407,232. Automatic musical instruments. ILES, G. B., The Gap House, Broadstairs, Kent. July 3, 1933, No. 18872. [Class 88 (i).] In a note-accenting device for an automatic piano or organ, each striking-pneumatic is provided with two valves b, c both of which, in the normal position, place the striking-pneumatic duct a in communication with the atmosphere through upper seats o, o<1>, and movement of one or other of which places the duct a in communication with high- or lowtension vacuum chambers d or e respectively through seatings n<1> or n, closes the open-airseat o or o<1> of that valve, seals the open-air-way through the air seat of the other valve and closes the communication to the vacuumchamber of the other valve. In the form shown in Fig. 1 the last-mentioned action is attained mechanically by means of a pivoted balanced lever g carrying cups i, i<1> which are pivoted downwards onto sheepskin seats r, to close the open-air-way of either valve, by the suction in the striking-pneumatic duct a, and there is a direct mechanical connection between the valves b, c, by means of stems b<2>, c<2> and the lever g, so that as one valve is lifted the other is lowered onto its seat n or n<1>. Fixed or screwadjustable leather buttons k may be provided on the stems b<2> c<2> or lever g. A modification, also shown, dispenses with this mechanical connection by providing one-way valves between the low-tension chamber and the striking-pneumatic duct a, which seal the lowtension chamber from the duct a even through the low-tension valve has been lifted from its seat n by the high-tension vacuum in the duct a. For this purpose a sealing-disc and washer rest looselv beneath the seat n on a collar provided on the valve-stem so as to be drawn up against the seat n independently of the valve by the high-tension vacuum. Alternatively a common low-tension vacuum-chamber is arranged below individual vacuum-chambers for each valve and communicates therewith through a one-way sheepskin flap-valve. In these forms the upper valve-seats o and r are both formed by a flat wood or fibre plate and the sealing-cups i, i are of wood and carry sheepskin seats. In a modification of the form shown in Fig. 1, the valves b, c are horizontallyopposed with aligned valve-stems b<2>, c<2> adjacent and bearing, if desired through leather-buttons, on opposite sides of a pivoted plate, the opposite cupped or flat faces of which form the seats for sealing the open air-ways. In all forms the valves are operated by supplying atmospheric air from the tracker-duct to purse-chambers m or ml, the purses l or l<1> of which have the usual bleed-holes.

Abstract: 807,317. Centreless grinding. SCRIVENER Ltd., A., and ADAMS, A. E. Sept. 9, 1957 [June 21, 1956], No. 19232/56. Class 60. A feed mechanism for a centreless grinding machine comprises a reciprocatory pusher rod k which advances workpieces c successively into a scoop e mounted above the gap between the grinding and control wheels a, b of the machine and has associated means for rotating the scoop and vertically-moving a cradle h so as to convey a workpiece from the scoop to a working position between the wheels and return it to the scoop. The workpieces, which may be in the form of wheel axles, are initially arranged on an inclined platform i so that actuation of a hydraulic piston-and-cylinder device n causes the pusher rod k to advance a workpiece into the scoop e, the movement of the workpiece discharging a completed workpiece from the other end of the scoop. The movement of the pusher rod is accompanied by movement of linear cams o, p which, respectively, engage projections r, y on vertically-movable racks s, 5. The vertical movement of rack s is transferred into rotary movement of the scoop e by means of a shaft u, at one end, connected to the rack by a pinion t, and, at the other end, connected by a chain w to the scoop. The vertical movement of the other rack 5 is conveyed by pinions 6, 8 on a hollow shaft 7, concentric with the shaft u, to further pinions 10 engaging vertical racks 11 on rods g formed with forked ends h comprising the cradle. In operation, a workpiece is advanced by the rod k into the scoop which, at a pre-determined point during the movement of the rod, is rotated 180 degrees for the workpiece to fall through an opening f in the wall of the scoop into the cradle.h. The workpiece is then lowered by the cradle into a steady d between the wheels a, b which are shaped to correspond with the configuration desired to be ground on the workpieces. At the completion of grinding, the pusher rod is withdrawn from the scoop and the cradle lifts the workpiece into the scoop which is then rotated to hold the workpiece until a further workpiece is pushed into the scoop.
