Title: An improved safety clutch device
IPC: F16D11/06
Filed: 1920-02-10
Abstract: 162,426. Regent Shears (1918), Ltd., Todd, B. W., and Batty, A. Feb. 10, 1020. Operating clutches.-In one-revolution clutchmechanism for power presses &c., of the type in which the crank-shaft A is clutched to the driving-fly-wheel by a rocking-key C, but is normally held uncoupled by the engagement of a spring- pressed arm D with a spring-pressed sliding and swivelling trigger H connected by a link N to the controlling arm or treadle, repetition of the stroke is prevented, even though the treadle &c. be held depressed, by the provision on the machineframe B of a roller P, against which an inclined face Q of the link N is held by a spring 0. In operation, the link N, normally engaging a pin I. by its hook M, pulls the trigger H against the spring R clear of the arm D, allowing a spring F to engage the clutch, as shown. The action of the parts P, Q then causes the hook M to disengage the pin L, allowing the spring R to return the trigger H into the path of the arm D, which, after one revolution, comes into contact with the trigger and thrusts it against a spring J, this movement being permitted by a slot in which its pivot K engages. As soon as the compression of the spring J overcomes the resistance, the arm D- is turned to declutch, and the spring again thrusts the trigger forward, so that it may be reengaged by the hook M on release of the treadle. Removal of the roller P permits drive as long as the link N is depressed.

Abstract: 447,516. Light - current relays. CARTON, J., Monts, Indre-et-Loire, France. Feb. 8, 1935, No. 4185. [Class 38 (v)] A moving-coil relay has an annular magnetic energizing field within which a coil is mounted so as to be displaced out of its normal position in one or other direction according to the intensity and direction of the current passing through the coil thus causing the circuit controlled by the relay to be opened or closed, the field being produced by two separate permanent or electromagnets and the coil forming part of a pivoted structure which is mounted to swing like a pendulum, that is, to either side of a vertical axis, the normal position being determined solely by gravity. As shown in Figs. 1 ... 3, the moving coil 12 is mounted in an annular air-gap 11 formed between a central core 10 and an apertured yoke 9, permanent polarizing magnets 6, 7 extending between the front and rear yoke members 8, 9. The moving coil is mounted on an insulating arm 13 extending downwardly from a transverse insulating bar 14 having pins 15 in conicallycupped bearings 16. The bearings contain mercury which is used to lead the current to the moving coil. The bar 13 carries a springing arm 19 with a contact 21 adapted to engage a fixed contact screw 21<1> when a suitable current flows through the moving coil. The gravity bias of the moving-coil structure may be varied by an adjustably weighted bar, Fig. 4 (not shown). The relay may be adapted additionally to act as an indicating instrument by the attachment to the moving-coil structure of a pointer moving over a graduated scale. If the relay is to be employed on A.C. circuits, the fixed magnet structure is modified by replacing the permanent magnets by electromagnets, preferably with laminated cores.
