Abstract: 397,850. Pulley-hoists ; brakes. QUICK, C. G., BALL, D. A., and BENNETT, T. R., 109, Borough Road, London. Feb. 29, 1932, No. 6078. [Class 78 (v).] A pair of arms 3, Fig. 2, supporting the roll feeding a printing-machine are carried by a shaft 5 which is operated, to raise and lower the arms, by a reduction gear comprising a cable 12 wound on a differential drum fast on a shaft 14 and passing round a pulley 15 on an arm 16 fixed to the shaft 5. The arms 3 are automatically held in any position to which they are moved by a pawl 26, Figs. 2 and 3, pivoted to the machine frame and engaging a ratchet wheel 24 loose upon but normally clutched to the shaft 14 through a friction clutch 23. The release of the clutch to allow the arms to fall by gravity is effected by a handle 17 acting through a control device which re-engages the clutch as soon as movement of the handle ceases. The handle 17 is operatively secured to a sleeve nut 19 engaging a threaded sleeve 22 keyed to the shaft 14 and carrying the clutch 23. A lug 18 on the nut 19 engages a slot 20<1> in a disc 20 fixed to the shaft 14. The weight of the arms 3 causes the nut 19 to press the wheel 24 against the clutch 23. Upon turning the handle 17 in the proper direction, the nut 19 is withdrawn to release the clutch, but this release is maintained only so long as the handle is turned to keep the nut withdrawn. The handle is separate from the nut 19 and operatively connected thereto by lugs 28 thereon engaging recesses in a flange 19<1> on the nut.

IPC: H01H73/30
Filed: 1918-04-10
Abstract: 124,906. Fernandez, A. April 10, 1918. Thermal c u t - outs. - A thermal cut-out which operates by the expansion of a wire to release the latching- device is set by a longitudinal movement of a handle, and the circuit can be m a n u a l l y opened, while the cut-out remains set, by the rotation and consequential longitudinal movement of the handle. The movable contact members 4, 5 consist of springs mounted in lugs on the base 1, and a contact 19 mounted on a spring 16 and adapted to engage a spring contact 24. The handle 9, Figs. 1 and 4, is mounted in a bracket 8 on the base. The bracket 8 also supports a resilient conducting member 10 adapted to hold a spring member 16 in its operated position. A hook 11 on the member 10 is connected by a conducting-wire 12, Figs. 1 and 9, to an adjustable hook 13 connected by a member 21 to the contact 19. The members 5, 16 are connected by an insulated bolt 39. To close the cut-out, the handle 9 is pushed until the member 10 engages the underside of the spring 16, when the contact 19 engages the contact 24 and the contact member 5 engages a contact member 27, Figs. 1 and 6. The circuit will then be completed as follows : Lead 7', members 5, 27, to lead 30; and lead 7, member 4, bracket 8, member 10, wire 12, member 21, contacts 19, 24, to lead 25. When the current through the wire 12 exceeds a predetermined value, the wire 12 expands sufficiently to allow the member 10 to disengage from the member 16, and the cut-out operates to open the circuit. To open the circuit when the cut-out is set, the handle 9 is rotated to cause a projection 38 thereon to engage a cam-surface 37 on the base 1, thereby producing a longitudinal movement of the handle 9 and causing the contact member 4 to disengage from the bracket 8, thereby breaking contact between the leads 7, 25. A cord 31, Figs. 1 and 6, is secured to the handle 9, and as the handle is rotated, it moves the contact 27 from the member 5 against the action of a spring 29, thereby disconnecting the lead 7<1> from the lead 30.

Filed: 1916-05-02
Abstract: 105,956. Stevens, W. A. May 2, 1916. Controllers, drum.-A reversing controller for an electric motor is arranged to short circuit the motor series-field before interrupting the supply to the motor. Two contact segments 1, 2 are carried by but insulated from the controller spindle. The segment 1 is long enough to engage the fixed contacts a, b in the zero position of the controller, while the segment 2 can only engage one of the contacts c, d. The generator e, motor armature g, and motor series-field coil h are connected to the controller as shown. As the controller moves back from the full ' on ' position, the segment 1 short-circuits the field coil h and the segment 2 then disconnects the motor and generator. When moved from ' off ' to ' on,' the motor and generator are connected before the short-circuit round the coil h is broken. In a modification, a resistance is connected in the lead between the contacts a, d for braking purposes.
