Abstract: 1360308 Stoning fruit GUNSON'S SORTEX Ltd 5 Jan 1973 [22 Feb 1972] 8138/72 Heading A4C Apparatus, suitable for stoning fruit such as cherries, comprises a blade 16 adapted to reciprocate at a stoning station 15 so as to  remove the stone 13 from each cherry 12 inturn, a hollow rotatable carrier 10 in which the cherries are presented in turn at the station 15, a plate 27 located so as to separate stoned cherries which remain in the pockets 11 of the carrier from unstoned or partially stoned cherries, a sonic transducer such as a microphone 21 located so as to be struck by each stone removed at the station 15. The microphone is connected to an ejector by a circuit including an amplifier, an adjustable level detector, abistable device (32), Fig.2 (not shown) and an amplifier (34). The device (32) is set as the blade 16 moves downwardly and closes a switch (35) and the device is reset when the microphone is struck by a whole stone. Signals from the microphone below a certain strength do not reset the device (32) so the ejector is operated only when the microphone has not been struck at all or by only part of a stone &c. At the ejector station 22 a stationary nozzle 23 receives a jet of air from the ejector and the unstoned &c. cherry is removed. The absence of a cherry from any pocket before ejection is detected by a member 26 which, if necessary, prevents resetting of the device (32). Compressed air or mechanical means may be used to increase the velocity of the stone as it leaves the cherry. A mechanical ejector may replace the pneumatic ejector at station 22.

Title: Improvements in hawking machines
IPC: D06B23/00
Filed: 1919-04-02
Abstract: 137,196. Wordsworth, G. H., Green, H., and Mitchell, I. April 2, 1919. Hawking type. - The rollers of hawking-machines are formed of a series of aluminium or like light metal or laminated wood sections having projecting boxes, which engage to form annular grooves between the sections to receive ordinary or special strippers. The rollers are centrally supported, and the leading-in roller is positively driven. Each roller is constructed of a series of sections a, Fig. 1, the projecting bosses a' of which fit truly against each other, leaving annular grooves. The bosses are mounted on shafts b, c and are nipped together by nuts screwed on the threaded outer ends of the shafts. A series of aluminium plates d forming strippers are mounted on strips e, carried on the front and rear bars f, g, and lie in the grooves. The strippers on the leading-in roller have extensions d<2> to ensure effective stripping. The rear roller is driven frictionally and has its bearing-blocks pressed by springs h against the front roller. To permit of its movement, the strippers of this roller are cut away at d<3>, and the openings a<1> for the bosses d<1> are extended laterally. The strippers may alternatively consist of floating rings i, Fig. 3, of aluminium or like metal, the depending surfaces forming the strippers. The rings have a slow creeping motion during operation, which ensures equal wear. In a further alternative form, the strippers may be shaped as shown in Fig. 1, but carried by the roller instead of by the strips e, slotted extensions engaging bars on the frame to keep the portions d<2> in position. In another construction, plates d, Fig 5, are used, carrying metal bands d<5> having a depending part d<2> and having their free ends forced into thickened parts of the plate d. If ordinary strippers are used, they are attached in each row individually to removable longitudinal bars to facilitate detachment, separate sets being provided above and below. A single set of strippers, entering the lower portion of the grooves and extending just beyond the roller centre, may be used on the rear roller. The machine is suspended centrally from a shaft k. The gearing can then be conveniently applied to drive either the leading-in roller only or both rollers.
