Title: Improvements relating to thermally-operated electrical switching devices
Inventor: ADAMS FRANCIS JOHN
IPC: H01H37/52
Filed: 1959-11-24
Abstract: 909,517. Temperature-responsive actuating- elements. PYRENE CO. Ltd. Nov. 7, 1960 [Nov. 24, 1959], No. 39859/59. Class 64 (2). [Also in Group XXXVIII] A fire-alarm or frost-warning switch of the type comprising two bi-metal strips mounted such that a relatively rapid change of ambient temperature is necessary to cause a temperature difference between them, thereby closing contacts, is characterized in that the two strips are the integral arms of a single piece of bi-metal, thus providing identical deflection characteristics of the two arms and ensuring non-operation by normal changes in ambient temperature. The strips 1 and 2 are stamped as a U-shaped member which is mounted at its base on a bracket 5 and bent into circular shape with the high-expansion side outwards for use as a fire alarm. The free ends of the arms carry insulated normally open contacts 7 and 8 which are connected by means not shown to terminals 4. The casing comprises a lower heat-insulating chamber 11 of mineral-filled melamine, for example, and an upper chamber 10 of thin aluminium blackened inside and close to strip 1. Thus slow changes in ambient temperature maintain a gap between contacts 7 and 8 but a rapid rise causes strip 1 to heat up more quickly than strip 2 resulting in closure of the contacts. A stop 6 in the path of contact 8 provides overriding actuation of the device at a predetermined high ambient temperature. The chambers 10 and 11 may be separated by a transverse partition through which the base of the U and one of the contacts extend. It is stated that one of the strips may be spring-loaded to provide snap action, or, alternatively, a switch actuated by the strips may be of the snap-action type. The device may be modified to respond to a fall in temperature, for example as a frost-warning device, by having the low-expansion side of the strips outwards. An auxiliary contact on the lower strip may co-operate with a stationary contact in series with contacts 7 and 8 such that rapid falls in temperature above a predetermined temperature do not actuate the device.

An hydraulic control for clutches 2, 3, e.g. in a tractor transmission, or for clutches and brakes in a planetary gear set, (not further described), comprises a distributer valve 11 connecting a fluid inlet 16 to one or other of fluid lines 18, 19 delivering fluid to the clutch cylinders to engage the clutches, and a spring accumulator 12 connected by a change-over valve 13 to whichever clutch, e.g. 2, as shown, is engaged, and operative, on rotating the distributor valve 11 to engage the other clutch, to maintain the first clutch engaged until the other clutch is engaged, when supply pressure in line 19 switches changeover valve 13 to recharge the accumulator. The clutch cylinders are exhausted through lines 18, 19 and outlet 17 in the valve 11. Again, Fig. 2, (not shown), four clutches are controlled, a further changeover valve (30) being inserted between the delivery lines (34), (35), of the two additional clutches (28), (29), and a third changeover valve (31) being inserted between the two valves (13), (30) and the accumulator (12). The changeover valve (31) comprises a floating piston (45) and two sleeves (43), (44) urged by springs (41), (42) away from the ends of the valve to abut fixed shoulders in the valve and the piston (45) to reduce the period during which two clutches are engaged. A stop cock (46) between the valve (31) and accumulator (12) is manually operated by a lever to disengage all clutches immediately if desired when the distributer valve (11) is moved to neutral. A one-way valve (48) connects the fluid inlet (16) to the accumulator (12). Again, Fig. 3, (not shown), two forward and two reverse clutches (2), (3) and (49), (50) are controlled by three identical changeover valves (13), (30) and (31) and an accumulator (12) connected to a further accumulator (56) by a restriction (58) and parallel one-way valve (59), the accumulator (56) discharging only after accumulator (12). The cross-section of outlet (17) is not constant, and the clutch supply lines (18), (19) and (51), (52) are not equally distributed around the valve (11), so that on changing from forward to reverse, both accumulators must be discharged before reverse gear is engaged.
