Abstract: To minimize space requirements, a small adjusting cam is mounted beside and projects below the side of the central housing of the pressure switch. The cam actuates a follower lever which, in turn, actuates an adjusting lever acting on the calibrating (pressure adjusting) spring plunger. The double lever arrangement achieves a motion multiplying effect permitting use of a small cam and, hence, reduces space requirements. The adjusting lever is movable about an axis, one end of which is adjustable by means of a calibrating screw which prevents transmission of forces from the calibrating tool to the lever and thus allows automatic calibration. The extra low setting of the pressure switch is determined by another calibrating screw fixed in the mounting bracket to prevent transmission of adjusting forces to the lever and permit automatic calibration. The cam may be rotated to an extra low position in which the follower lever has no effect on the position of the adjusting lever, the position of the adjusting lever being determined solely by the extra low calibrating screw. A second extra low setting is provided, in which position the cam actuates an arm which may be connected to a clutch or switch altering the speed of a timer, for example, to permit alteration in the operational characteristics of the washing machine in combination with the extra low setting.

Abstract: When a cycle selection button is depressed, it causes a selected wire to be torsionally stressed to cause the selected pin to be biased downwardly against the surface of the rotary disc. The disc is carried by the timer shaft which is moved outwardly during the selection/positioning operation. The disc has various radially and circumferentially positioned holes into one of which a selected pin may drop to thereby correctly position the timer at the start of the selected cycle. Three holes are provided in the disc on the radius of the ''''soak'''' pin and a masking arrangement covers or uncovers, as the case may be, the ''''soak'''' holes so only that hole which properly combines with the selected cycle is operative. The masking arrangement is actuated by one of the possible cycle pins. Therefore, a ''''soak'''' period may be selected to precede any of a number of cycles while employing only one ''''soak'''' button and one ''''soak'''' pin.
Abstract translation: 当按下循环选择按钮时，它使得所选择的导线受到扭转应力，使得所选择的销向下偏压抵靠旋转盘的表面。 该盘由在选择/定位操作期间向外移动的定时器轴承载。 盘具有各种径向和周向定位的孔，其中一个选定的销可能下降，从而在所选循环开始时正确地定位定时器。 在“浸泡”销的半径处的盘中设置三个孔，并且掩蔽装置覆盖或露出（视具体情况而定）“浸泡”孔，因此只有与所选周期适当组合的孔才可操作。 掩模布置由可能的循环引脚之一致动。 因此，在仅使用一个“浸泡”按钮和一个“浸泡”针的情况下，可以选择“浸泡”时段在任何一个循环之前。

Abstract: Refrigerant flows from the compressor and condenser to the evaporator by a thermostatic expansion valve having its pressure and temperature sensing points in the suction line downstream of the evaporator outlet control valve which regulates the evaporator pressure relatively independently of the suction line conditions. When the compressor capacity significantly exceeds evaporator capacity this system provides additional compressor cooling at low suction pressures. The expansion valve may be the bulbless type or the externally equalized type. The outlet control valve may respond to refrigerant temperature at the coil outlet, or to fin temperature, or may be an evaporator pressure regulator valve.

Abstract: The switch-selector shaft is depressed to move latch plate against core magnetized by permanent magnet. This actuates various switches depending upon rotary position of the shaft. The termination pulse from the moisture sensing control passes through a coil to set up a counter magnetic field to allow a spring to move the latch and shaft to inactive position restoring switches to their normal positions.

Abstract: Depressing one of the cycle selection switches sets up a circuit through the shaded pole motor to drive the timer at high speed until the wiper on the end of the cam arbor finds an open circuit on the printed circuit board. During the high speed advance of the timer, the machine circuits are de-energized and, upon finding the open circuit, the shaded pole motor is de-energized, the machine circuits are energized, and the timer drive motor is actuated to sequence the timer through the selected cycle. The stepping mechanism is operated by the slow rise fast drop cam operating a pawl which engages the ratchet teeth on the cam arbor. Particularly during high speed advance, there may be a tendency for the arbor to overstep and, therefore, the pawl, in effect, is a double pawl or verge which jams two teeth at the conclusion of a step. This locks the ratchet in the stepcompleted position. Switching during an interval is accomplished by means of cams associated with the stepping cam and actuating sub-interval switches. This enables the performance of various functions during an interval of the timer. This type of timer is generally referred to as a power timer.

Abstract: The force or degree of compression of the spring is adjusted by rocking the lever about its axis A-B by means of the manually operated cam acting on the lever at D. Calibration is effected by adjusting the screw at B to rock the lever about axis A-D. Any tool forces applied to the adjusting screw during adjustment cannot be transmitted to the spring to adversely affect calibration.

Abstract: The pressure switch comprises a toggle switch in which a flexible switch tongue is moved by a pressure-actuated diaphragm against the force of a return spring, and a contact-carrying flexible switch blade, connected to the blade tongue, through an overcenter spring, is moved by snap-action in one direction as the blade tongue moves through the overcenter position in the opposite direction: To effect a safety function; a contact is movable by the switch tongue to engage a stationary contact after a predetermined movement of the switch tongue past the overcenter position, the switch tongue being movable despite the possibility of welding of the toggle switch contacts. Closure of the safety switch by the switch tongue in this way can be used to energize a pump in the event of failure of a water valve to close or to energize a water valve otherwise prevented from energization by welding of two of the toggle switch contacts.

Abstract: The Y-shaped stop device frictionally engages the gear shaft and tends to rotate with the gear. The freedom of movement of the device is restricted by the selector to permit a selected arm of the Y to be effective. If the pinion gear starts in the wrong direction, the stop wing carried by the rotor will strike the effective arm which has been frictionally rotated into a position which insures optimum starting conditions for rotation in the desired direction. Upon engagement the rotor starts in the desired direction and the friction acting on the stop device moves the arm clear of the path of the stop wings. The selector limits movement of the stop device to keep the other arm clear of the stop wings.

Abstract: In one modification the diaphragm pad or plate has a post engaging the spring seat which fits loosely in the housing to avoid interference. The spaced shoulders between the spring seat and the post provide the necessary lost motion connection to the switch actuating tongue which fits over and guides the post. In the other modification the post is guided by the tongue which fits in the notches on the post. The spring seat member is eliminated and the spring seats on the post. This design reduces the number of requisite parts and reduces friction impairing repeatability of the performance.
