Abstract: 203,179. Caufield, N. H. Aug. 28,1922. Shocking-machines.-The sheaves are delivered from a binder into a basket consisting of side-members mounted in bearings 20 on the main frame 1, a pivoted bottom 99, forward end 63 and a normally open top-piece 43<a>. The sidemembers are formed by plates 30, 31 inclined inwardly toward the rear and carried on bare 24, 26, 27, 32, the bars 24 be,ing supported by the bearings; the upper edges of the plates 30, 31 are formed as outwardly extending flanges 34, 35, and plate springs 36, 37 are fitted at their rear ends. The main frame 1 is connected on one side to the binder and is supported on the other by a wheel 2 carrying a sprocket 3 driving through a chain a sprocket 4 that may be clutched to its shaft 5 'by moving a link 17 to shift a laterally-projecting rod 15 clear of a clutch-operating lever 13. The shaft 5 aud a corresponding shaft 49 at the other side of the frame to which it is connected by a cranked shaft 46 carry cams 110, 111 operating levers 106, 107 for swinging the sidemembers between their horizontal and vertical positions. Each forward bar 32 of the side-members carries an L- shaped bracket on which is pivoted a normally vertical arm 42, the two arms being connected by the curved plate 43<a> that closes the front of the basket when the latter is swung to the vertical position for depositing the shock. The arms 42 are operated through spring-pressed telescopic links 44 by the cranked shaft 46. The bottom of the basket in its depositing position consists of a plate 63, preferably fork-shaped that normally hangs vertically in front of the wide forward end of the basket from the bars 64, 65 pivoted on the frames of the side-members and connected, through slotted links, with bell-crank levers 75, 76 mounted on the pivots of the side members and operated by rods 80, 81 from the shaft 46. The front side of the basket as it attains its depositing position is formed by a curved plate 99 extending between two bars 94, 95 that lie alongside the bottom bars of the sidemembers and that are attached at their rear ends to the rear ends of the top bars of the side-members by links 96, 97; links 92, 93 extend also between the forward ends of the bars 94, 95 and the bottom bars of the side-members, links 90, 91 connecting these links intermediate of their ends to arms of the bell-crank levers 75, 76. In operation the sheaves are delivered by the binder to the basket in its open position, Fig. 1, in which the forward end of the basket is covered by the plate 13 which at its upper end in this position engages within jaws formed on the bracket carrying the arms 42; when the desired number of sheaves has accumulated the attendant throws in the one-revolution clutch by operating the link 17, and the shaft 5 begins rotating, causing the basket to be swung into its vertical position by the levers 106, 107 and simultaneously moving the plate 43<a> forward to compress the shock in the basket. After the basket has attained its vertical position the plates 99, 63 are swung clear of the rear and the bottom of the basket respectively by the action of the bell-cranks 75, 76, thus permitting the shock to be deposited on the ground. The further rotation of the shaft 5 operates the levers 106, 107 to bring the basket with the plates 99, 63, 43<a> into receiving position, Fig. 1. Spring catches hold up the arms of the plate 63 until the basket has reached such a position that theplate 63 can be released without danger of striking the soil, and stops check the movement of the basket when it attains the receiving position.
