    Abstract: A lock unit secured within a base cavity in a cradle telephone includes a reciprocal angle plate susceptible of being releasably locked in a lowered position wherein its top portion spans the circuit controlling yieldable plungers to hold the same depressed with the receiver, which normally controls said plungers, either seated in its cradle or removed therefrom, whereby unauthorized use of the telephone is prevented. When the unit is unlocked said angle plate, under the projective force of said spring urged plungers, will, when the receiver is removed from the cradle, where it overlies said angle plate, move upwardly with the plungers to activate the telephone circuit and thus allow normal, authorized use of the telephone set.

    Abstract: The retractable and extensible shackle of the present padlock is formed with a section, which includes the short leg of the shackle, which section is deflectable relative to the remainder of the shackle when the shackle is released from the padlock body and projected away therefrom, thereby giving the shackle a wide mouth for easy entrance thereinto of a bar or other fixed element of an item to which the padlock is to be applied. Then, when the deflected portion of the shackle is returned to its normal position and the retracted shackle is secured within the padlock body the shackle will so closely encompass the engaged bar or element that there will be no room for the application of a cutting tool by a prospective thief.

    Abstract: For the protection of the outer end portion of an internal combustion engine exhaust pipe, a protector is available which includes a collar secured to the outer end portion of the exhaust pipe hingedly carrying a protective cover formed with a weighted, radially outwardly projecting fin. The cover normally overlies and closes the open outer end of the exhaust pipe to which it is applied but will hingedly move to open position through exhaust gas pressure. This invention provides a lock for securing the cover in its closed position to prevent the undesired introduction of foreign material into the discharge end of the exhaust pipe when the engine is not being operated and the equipment or vehicle embodying the engine is idle and unattended.

    Abstract translation: 为了保护内燃机排气管的外端部分，可提供保护器，该保护器包括固定到排气管的外端部的轴环，该轴套铰接地承载形成有加权的径向向外突出的翅片的保护盖。 盖通常覆盖并关闭其所施加的排气管的敞开的外端，但是将通过废气压力铰接地移动到打开位置。 本发明提供了一种用于将盖固定在其关闭位置的锁，以防止当发动机未被操作并且体现发动机的设备或车辆空转和无人看管时异物将异物引入排气管的排放端。
