locking position. As soon as the ball moves arm and stops the ringing of the bell. 30

Ward which retains the detent arm in the to the slightest extent the pin will be released and the spring will act to tilt the lever, the, I pin moving upward in hole 21 and the right arm of the lever swinging downward and releasing the detent arm, which causes the operating mechanism to ring the bell. 'I he ball when it settles back to place will roll against the pin but cannot move the pin downward the ball will be stopped against one side of the pin, so that the ringing of the bell will continue until the operating mechanism if controlled .by a spring has run down, or if electric ringing mechanism is used, so long as the battery holds out unless it is stopped by the operation of the look. A person knowing the combination can stop the ringing of the bell by setting up the combination and mov"" ingthe locking bolt to the unlocking position; that is, toward the left from the position The movement of the looking bolt to the unlocking position swir igs the stopping lever and moves the lower end of said lever, which is now in engagement with lever 16, downward, swinging the right end of lever 16 upward which raises the detent 'lhe oscillation of lever 16 moves pin 20 downward to the position shown in ig. 1 against the .power of the spring and permits the ball to 'roll to its normal position on top of and in engagement with the end of the pin, as in the drawing, andretains the parts in this osi tion against the power of the spring unti the ball is again displaced.

Having thus described my invention, I

1. An alarm of the character described comprising bell mechanism having "a detent arm, a pan having a dish-shaped bottom with a central hole, a ball in said pan, a lever one arm of which engages the detent arm the other arm being provided with a pin project ing through the hole in said pan to be engaged by the ball to lock the bell mechanism out of operation, and me ans for tilting the lever and releasing the bell mechanism when the ball is displaced from the end of the pin, the pin being of a length to form a stop to prevent the ball from rolling back over it when said pin is'raised. Y

2. An alarm of the character described comprising hell mechanism having a detent arm, a pan having a dish-shaped bottom with a central hole, a ball in said pan,- a lever one arm of which engages the detent arm the other arm being provided with a pin projecti.

ing through the hole in said pan to be eni gaged by the ball to lock the hell mechanism 1 out of operation, and a springbearing upon 1 one arm of the lever to tilt said lever and release the bell mechanism when the ball is displaced from the end of the pin, the pin being of a length to form a stop to prevent the b from rolling back over it when said pin is raised.

3. An alarm of the character described comprising bell mechanism having a detent arm, a pan having a dish-shaped bottom with a central hole, a ball in said pan, a lever one arm of which engages the detent arm the other arm being provided with a pin projecting through the hole in said pan to be engaged by the ball to lock the bell mechanism out of operation, means for tilting the lever and releasing the bell mechanism when the ball is displaced from the end of the pin, the a pin being of 'a length to form a stop to prevent the ball from rolling back over it when said pin'is raised, and means for returning the lever to itsnormal position against'the power of the spring and permitting the ball to again engage the end of the pin.

' 1. An alarm of the character described comprising bell mechanism having a detent arm, a pan having a dish-shaped bottom with a central hole, a ball in said an, alever one arm of which engages the ctent arm the other arm being provided with a pin projecting througlf the hole in said pan to be engaged by the ball to lockthc bell mechanism out of operation, means for tilting the lever and releasing the bell mechanism when the ball is displaced from the end of the pin, a stopping lever for returning the lever to its normal position,*a locking bolt and a cohnection betwcenthe locking boltand the stopping lever.

.5. .in alarm of 'the character described comprising bell mechanism having a detentarm, a pan having a dish-shaped bottom with a central hole, a ball in said pan, a lever one arm of which engages the detentann and the i other arm being provided with a pin pro ecting tln'ough the hole in said pan to be engaged by the ball to lock the bell mechanism out of operation, means for tilting thevlcver and releasing thebcll mechanism when the ball is displaced from the end of the pin, the pin being of a length to form a stop to revent the ball from rolling back over it w en said pin is raised, a stopping lever one end of which is ada ted to engage the lever, for the purpose set mm, a locking bolt an'dan arm pivoted to the locking bolt and connected to the stopping lever.

In testimony whereof I affix my signature, in presence of two witnesses. V
