Filed: 1925-08-24
Abstract: 238,906. Tecalemit, Ltd., (Assignees of Fouquet, E.). Aug. 22, 1924, [Convention date]. Connecting fixed lubricators with moving apparatus; controlling flow of lubricant.-Lubricant is supplied to passages in the pivot pins of chains through a nozzle 13 arranged in a casing 12 containing a valve, the casing 12 being mounted in a member 2 pivoted to a sprocket-wheel 4 over which the chain passes. The member 2 carries a roller 6 engaging a stationary cam 8, so that, as a pin comes on to the sprocket-wheel, the member 2 is rocked about its pivot 3 by the action of the cam 8 to bring the nozzle 13 into engagement with the head of the pin. A cam 9 then causes the valve to open. Before the pin leaves the wheel 4, the valve closes and the member 2 is pushed back by springs 10. The cam 8 and roller 6 may be dispensed with, the spring 16 pressing the valve towards its seat being stiffer than the springs 10, so that the member 2 is rocked about its pivot 3 before the valve is opened. In the Specification as open to inspection under Sect. 91 (3) (a), Specification 238,580 is referred to, but this reference does not appear in the Specification as accepted.

Abstract: 492,620. Thermally - actuated valves. SCHOENFELD, F. H. Aug. 10, 1937, No. 22024. [Class 135] A thermally-actuated valve of the kind in which a lever is pivoted in a frame mounted in the valve casing and is acted on by a thermostatic element while supporting a secondary lever which is adapted to act on the valve, the secondary lever being under the influence of a spring connected with the frame for effecting a snap action of the secondary lever, has the frame provided with alternative seats for the pivots of the main lever so that the device may be arranged to close with rise of temperature and act as a temperature regulator or high temperature cut-off or may be arranged to close with fall of temperature to act as a safety-cut-off under the control of the pilot burner. Fig. 2 shows the device arranged as a temperature regulator. The expanding tube 51 has an adjustable screwthreaded connection with a rod 50 bearing on the main lever 40 which is offset at the top and provided with knife edges 43. The lever 40 is bent at right-angles at the bottom and is bifurcated to provide bearings for the secondary lever 54. This lever has an offset stop 53 working in an aperture in one side of the frame 30 and is loaded by a spring 60 anchored to an eye 61 on the frame 30. The upper end of the lever 54 is bent twice at right-angles to provide an abutment adapted to unseat the valve member 67 against the action of a spring 70. This spring is housed in a removable closure member 72 which also carries a guide 74 for the valve spindle 65. The thermosensitive element is adjusted by an arm 78 clamped by a set-screw on the rod 50 and the leverage of the main lever is varied by shifting the frame 30 bodily by means of a crank disc 86 on a spindle 84 passing through a stuffing box to the outside of the casing where it is provided with a manipulating head 85. The valve is shown in the open position, on the thermal tube expanding the lever 40 turns clockwise moving the fulcrum of the lever 54 to the other side of the spring anchorage so permitting the spring to snap the valve closed. The opening movement is aided by a spring 75. When used as a high temperature safety cut-off a spring-loaded sliding catch is provided to lock the lever in its retracted position after the valve has closed. When used as a pilot-burner controlled safety cut-off the device is inverted and the lever knife edges are moved to the alternative shoulder so that the thermal element engages the lever between the pivot and the end carrying the secondary lever.
