Title: Improvements relating to grabs, grapples and the like
IPC: B66C3/10
Filed: 1947-06-27
Abstract: 627,807. Grabs. PRIESTMAN BROS., Ltd., and CHILD, A. June 27, 1947, No. 17081. [Class 78 (iv)] The jaws 5 of a grab or grapple suspended from and operated by the rope of a single-line crane or the like are connected to two crossheads 8, 9 sliding in a frame 6 so that one crosshead 8 rises and the other, 9, falls when the jaws are opened. A block 7 sliding in the frame 6 and connected to the suspension rope carries a hook 10 for engaging a stud 12 on the crosshead 8, while the crosshead 9 carries a member 23 adapted automatically to disengage the hook 10 when the crossheads 8, 9 are close together and the load on the hook is relieved. The jaws 5 are arranged in pairs joined by stays 15, 16'on a shaft 14, and are connected by links 19 to the crosshead 8 and by crossed arms 17 and links 21 to the crosshead 9. The chain 26 by which the grapple is suspended is attached to a shackle 26 on the sliding block 7 and passes through a guide eye 27 on a crossbar 13 ending in an eye 28 for suspension from the hook of a crane. When the jaws 5 are open the crossheads 8, 9, lie close together on either side of the block 7 so that when the grapple rests on the load with the chain 25 slack the hook 10 pivoted at 11 to the block 7 is disengaged from the stud 12 by a weight 23 having a pin and slot connection 24 with the crosshead 9 and which engages the tail 22 of the hook 10. When the grapple is raised from this position the crosshead 9 is lifted by the block 7 to close the jaws 5 on the load. When the load is subsequently lowered and the chain 25 slackened the block 7 descends until the hook 10 engages by gravity around the stud 12 on the crossbar 8, so that when the grapple is again raised, the crossbar 8 is pulled up to open the jaws. A dashpot 29 damps the opening movement of the jaws and preferably acts only in one direction. The sliding weight 23 may be replaced by a spring device and other forms of jaws may be used. The block 7 preferably has shoes 33 guiding its sliding motion in the frame 6. Specification 30459/09, [Class 78 (iv)], is referred to.

Kinematograph apparatus.-In apparatus comprising a film-controlled cut-off shutter, means is provided, operated by the shutter releasing mechanism, to prevent the shutter from being opened until the shutter controls have been reset. As shown, two vertically-sliding shutters a<1>, a<2> are connected by pins and slots to a T-shaped lever c<1> which is mounted on a spindle c and is urged by a spring c<3> into a position such that the shutters close the light aperture n. The spindle carries a commutator j and a catch wheel j<1> which is normally engaged by a catch piece k<2> on a lever k<1> pivoted at k. The armature h<1> of a solenoid engages the lever k<1> so as to release the catch wheel when the solenoid is energized; energization is effected by the closure of film-controlled contacts. The commutator breaks the driving- motor circuit when the shutters are closed. The end of the lever k<1>, when lifted, engages the end m' of a plunger so as to press it, against the action of a spring, into a position such that, after the shutters have closed, it prevents the shutter a<2> from being raised until the solenoid is deenergized. The switch-actuating arms engaging the film are mounted on spindles t, Fig. 5, projecting externally of switch boxes. Each spindle t carries an insulating arm t<2> which presses a contact spring s into engagement with a spring contact plunger r to complete the circuit. A condenser within the box is connected across the contacts. According to the earlier Provisional Specification, the spindle in the lower switch box carries four spring arms bearing contacts, and the shutter carries a spring-pressed wiper engaging contact surfaces to make and break the motor circuit. According to the later Provisional Specification, the end of the horizontal arm of the lever k<1> is forked, one branch being connected to the solenoid and the other carrying a cam or wedge serving to prevent the raising of the shutter.

IPC: G03B37/04
Filed: 1926-07-10
Abstract: 255,095. Nistri, U. July 11, 1925, [Convention date]. Aeronautical photography. - Apparatus such as cameras mounted on aircraft are operated by means coupled to a constantly rotating driving-shaft at regular and adjustable intervals by apparatus comprising a clockwork mechanism and an adjusting device, inserted between the clockwork and the coupling means. In the form shown, the shaft 31, Fig. 2, operates the camera &c. and is intermittently connected to a power-driven shaft 24 through the clutch 29, 30 by means of a fork 22 operated from a toothed wheel 10 driven at a constant speed by a spring 11 under control of an escapement 14. The spring 11 is connected at its inner end to a central axle, to which is secured a worm-wheel 15. The length of the interval is set by turning the head 3, Fig. 1, of a graduated disc carrying on an arm a pin 4, against which an arm 7 is returned immediately following a coupling- operation, and from which it is carried round by the wheel 10 until it reaches a pin 32 and turns a lever, carrying the pin 32 and bearing a cam, so as to free the cam from the tooth 18<1>, Fig. 3, of a sliding part 17 carried upon and rotating with the wheel 15, the part 17 being then drawn by springs 19 to disengage a tooth 20 of the part 17 from the fork 22, which is then turned by a spring 34 to engage the clutch 29, 30. A tooth 8 on the arm 7 engages the wheel 10 when kept in its lowered position by a spring 9, disengagement being effected by means of the wheel 15, which is driven by a worm on the shaft 31 and immediately upon commencing its rotation depresses by means of a cam one end of a pivoted lever 35 and so lifts a rod 6 bearing at its upper end the arm 7, which is returned by a spring to its initial position in contact with the pin 4. Continued rotation of the wheel 15 releases the lever 35, so that the tooth 8 falls into engagement with the wheel 10 and begins its second movement towards the lever 32, but before this movement is completed, the wheel 15 has completed a revolution and the part 17 has been returned by the cam 32 to strike the fork 22 and disengage the clutch 29, 30 and thus stop the shaft 31 and also the wheel 15 in readiness for the next clutch engagement. In its rotation, the wheel 15 re-winds the spring 11. Counting- mechanism operated by the wheel 15 indicates the number of operations of the shaft 31.
