To all whom, it may concern,.-

Be it known that I, JOSEPH GoNoEovsKv, a citizen of the United States, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Time-Locks, of which the following is a specification.

This invention relates to a time-lock for toy savings banks and other receptacles which is of novel construction and reliable in its operation.

In the accompanying drawings, Figure lis a front elevation of my improved time-lock; Fig. 2, a vertical section on line 2 2, Fig. 4; Fig. 3, a vertical section on line 3 3, Fig. 4; Fig. 4, a horizontal section on line 4 4, Figs. 1 and 2; Fig. 5, a detail of the worm shaft and wheels, and Fig. 6 a modification of the same.

The letter a represents the body or box of a toy savings-bank or other receptacle to which the time-lock is to be applied. This receptacle is provided with a hinged door a', having a pivoted latch 0.2,that may be operated by a knob a3. To the box d is suitably connected the casing b of a clockwork having lthe usual dial b and hands b2. The clock-arbor b3 carries a worm b4, that intergears with a wormwheel c', fast on one end of a shaft c, which is rotatable in bearings c2, Fig. 5. The other end of shaft c carries a worm c3, that meshes into a wormwheel d', fast on a spindle d, which is rotatably supported "in bearings of box a. The spindle d is axially movable in its bearings, so that the wheel d may be thrown into or out of engagement with worm c3. A pointer di, movable over a dial c of box a, is mounted upon the front of spindle d, while at its rear end the spindle carries a handle d3 and is surrounded by a spring d?, that normally draws the spindle back, so that the wheel d is brought into alinement with worm c3. Upon the spindled is further mounted a disk f, provided at its circumfercnce'with a notch f and ,with a pin f2, that extends through the notch to a point slightly beyond the periphery of the disk. This pin f2 engages the slotted Ainner end g' of a lever g, turning on fulcrum g2 and having a double concave rear face g3 of a curvature corre sponding to that of disk f. The forked outer end g4 of lever g engages a pin h on one arm h? of an elbow-lever turning on fulcrurn h3, the other arm h of which constitutes thc upper detent of latch 0,2. The detent h is arranged in the path of the latch 0.2, but does not interlock or contact with the same, so that during an attempt to swing the latch the strain is not transmitted to the clockwork. The lower detent of said latch turns on fulcrum t" and is inuenced by a spring ft2. The detent c' is arranged at a distance from the detent a so as to accommodate and confine the latch a2 between the detents. A stop g5 below lever g relieves the clockwork from pressure of the locking device.

The operation is as follows: To set thetimelock, the spindle dis pushed forward by handle d3 until wheel d clears worm c3, and then the spindle is rotated in the directionof the arrow, Fig. l, to set the pointer (12150 the time at which the door is to be opened. Upon releasing the spindle the wheel d will be drawn into engagement with worm c3 byspring d, so that it will be set in motion by the clockwork. The door is then closed and will re; main locked until the time to which the pointer is set is about to expire. At this time the rotation of the pin-disk f, moving along 'lower concave rear edge g3 ofrlever g, has

brought its pin f2 into engagement 'with the slot g' of lever g, and thus said leverg will be swung with its outer end upward. In this way the arm h2 is also tilted, and the detent his withdrawn from the path of latch a?, so that the door a. may be opened by turning the knob a3 and swinging the latch a2 upward. Should the exact time be missed at whichY the door is to be opened, the lock will nevertheless remain open, because the further rotation of disk f will swing the rear upper concave face g3 of lever g against the periphery of the disk, so that the lever remains locked in its tilted position and the detenth remains withdrawn. When the time-lock has been reset, the detent h will thereby be swung into its normal position, Fig. 2, and therefore the latch a2 must be swung down before thedoor is closed. After the door has been closed the latch is swung up past the momentarily-yield- IOO between the detents.

In Fig. G the Worm-shaft o is replaced bya worm-shaftj, stepped in a fixed bearingjl and turning in a sliding bearingj?. In ILhis modification the engagemenubetween the worm- Wheel d' and the Worm j may be interrupted b y swinging the shaft sidewise (dotted lilies) in lieu of displacing the shaft; d axially, as in Fifzs. L and 5.
