Abstract: An iron-type golf club head is disclosed that comprises a striking face, a heel, a toe and a sole bar, wherein a recess is formed in the sole bar. A cartridge comprised of a first material at least partially disposed the sole recess, and at least one pin, comprised of a second material coupled to the cartridge. The first material has a modulus of elasticity that are less than that of the second material.

Abstract: A circuit breaker composed of a contact spring fixed at one end, carrying a movable contact at its free end and biassed to urge the movable contact away from an associated fixed contact, a switching rocker pivotally mounted to selectively move the spring into a contact closing position, and a release device arranged to move the spring into the contact opening position independently of the position of the rocker, is further provided with a latching lever which extends approximately parallel to the contact spring, is mounted to be pivotal in a direction parallel to the direction of movement of the spring and of the rocker, and is operatively connected between the spring, the rocker and the release device.

Abstract: Thermostats for use in electrically heated appliances have a positive off position and are adapted for transition to a low temperature on position within a small amount (approximately one radian) of control shaft rotation. The thermostats comprise a stacked blade assembly including a lower bimetal temperature responsive blade, an intermediate stiff spring blade and an upper less stiff flexible spring blade, with the spring blade having juxtaposed switch contacts thereon and the bimetal blade operating to separate the switch contacts when the set temperature is attained. A control bracket mounted above the stacked blade assembly defines an opening through which a control shaft extends, the control shaft butting against the stiff spring blade and positioning it. The shaft mounts a cam and the control bracket has a depending cam follower for the cam, wherein the spring blade urges the cam against the cam follower.
