Abstract: 297,105. Brackett, E. M., and Brackett, F. M., (Assignees of Daneke, D.). Sept. 16, 1927, [Convention date]. Delivery apparatus.-In a cutting machine the sheet to be severed is positioned by a movable gauge controlled by adjustable stops on a cylinder rotated through a slipping clutch from a constantly rotating shaft, when freed by a detent actuated from the knife slide. The knife 6 is reciprocated in side guides from a crank 16 and is connected by a pin and slot with a clamp-bar 24. An end gauge for the sheet is positioned by a finger on the gauge engaging stops 5<1> adjustable in grooves in a cylinder 56. A sectional ratchet cylinder 60 is connected through a slipping clutch 72 with a constantly rotated shaft 67. A pawl 86 is adjustable on a shaft 85 to release one of the ratchets on cylinder 60 when the shaft is rocked against spring pressure by a finger 90 on the knife slide. The ratchet cylinder 60 comprises wheels with 1, 2, 3, &c. teeth. By adjusting the pawl to engage the appropriate wheel and setting the stops 5<1> the number of gauge settings per stroke of the gauge may be varied. A delivery table is mounted on a pivoted arm connected by a rod 98 to a cam plate 102 on a shaft 101 rotated through a slipping clutch from a power shaft. Movement of the cam 102 is controlled by fingers 116, 117 associated with sliding bars 118, 119 which are selectively actuated by adjusting pins 1<c> in extreme positions in a member 125 on the cylinder 60. When the pins are in central position the delivery table is not actuated.

In a direct current measuring device of the type comprising a core of ferromagnetic material which is adapted to encircle a current carrying conductor portions of the core being moved relatively one to another to enable the device to be placed around or removed from the current carrying conductor and comprising means for indicating, in dependence upon the magnitude of the flux induced in the core, the current flowing through the conductor, the instrument is rendered more sensitive at relatively low current values by magnetically polarizing the core. The polarization of the core may be carried out by including in it a portion of permanent magnetic material or a permanent magnet may be arranged to cross the gap in the core in which is mounted the indicating instrument movement. Alternatively, the core may be polarized by means of a winding thereon energized from a direct current source or from an alternating current source through a rectifying means. The instrument movement arranged in the gap of the core may be either a soft iron movement, a permanent magnet movement, or alternatively may comprise a moving coil energized from a direct current source. The invention may be applied to the measurement of direct current or in other instruments such as watt meters in which the quantity to be measured is dependent upon the current flow in a conductor.
