TIME LOOK FOR nut roivronrnns.

specification of Letters Patent. Patgntea lu 16 1922 Application filed June 18, 1920; Serial No. 389,977.

time locks and more particularly to a time lock especially; adapted for use on automobiles to lock a switch in an electric circuit to prevent movement of the vehicle until apredetermined time.

The objects of the invention are the provision of a time lock controlling a switch in an electric circuit from the, battery and magneto, a solenoid controlling a throttle valve in the intake manifold in the engine being also included in said circuit. I

These objects together with other objects are attained by providing a clock mechanism having any usual and well known time operated mechanism contained therein and located adjacent to a. switch in an electric circuit from the battery and magneto, a

solenoid controlling the operation of a valve in the intake manifold being also included in said circuit, means being provided for opening said switch and holding the same locked in the open position until such time as the time mechanism upon the clock is set to operate at which time the switchwill be automatically closed.

With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and.

minor details of construction may be made within the scope ofthe appended claims, without departing from the spirit or sacristrument board showing the mechanism in elevation.

Fig. 3 is a rear elevation of the mechanism, parts beingbroken away for the purpose of illustration.-

Fig. 4 is a sectional view through a portion of the switch.

Fig. 5 is a diagrammatic view of the wiring ofthe device.

A practical embodiment of the invention is disclosed in the accompanying drawings, forming a part of this specification in which similar numerals of reference indicate, corresponding views.

The instrument board of an automobile is indicated bythe numeral 1 and the clock 2 is housed within the instrument board, being preferably provided wit-h an annular flange 3 by means of which the clock is permanently attached to the instrument board.

The clock 2 may be of any usual or well known design of time or alarm clock and is provided with the small dial 4 having the indicating hands 5 which may be set at any predetermined time to automatically operate the alarm mechanism in the usual manner. A stem 6 is provided for setting the alarm mechanism and this stemis preferably removable in order that the mechanism may not be tampered with after the time mechaparts throughout the several nism is set.

The battery is indicated by the numeral-7 and the magneto by the numeral 8, the wires 9 and 10 being connected to the battery and to the, magneto the wire 9 being connected by means of the wire 11 to the solenoid 13, the armature 14 of which is pivotally connected, by means of the link 15, with anarm 16 which is rigidly attached to the butterfly valve 17 located in the intake manifold 18 of the engine.

The wire leads to the switch member 19 upon which is located a pivoted switch arm 21, said arm being normally held in contact a contact point 12 by means of the wire 12,

a wire 1O connecting the wire 10 with a similar contact point 12*. A spring. 14 is located around the armature and interposed between the solenoid and thrust collar 1 3 to normally ur -e the armature into the position shown in 4 ig. 5 to hold the valve 17 in the open position.

A plunger 23 is slidably mounted through the top of the instrument board and through adoearing bracket 24; and is provided with a thrust collar 25 being fixed upon said plunger between the bearing and the top of the instrument board, a. coil spring 26 being located around the plunger between the bearing and said collar to normally hold the collar in engagement with the instrument board holding the head 27 oi the plunger normally out of engagement with the arms 21 oi the switch.

The plunger is provided with a notch 28 arranged to be engaged by the spring pressed pawl 29 which is pivoted at 30 upon the rear of the clock and a tail 31 is provided upon said pawl arranged to be engaged by the tappet 32 upon the disk 33 which is arranged to be rotated in the direction of the arrow shown in Fig. 3 by the operation of the alarm or time mechanism in the usual manner.

A plunger 35 provided at its extremity with a switch member 36 is slidably mounted in the upper end of the tube 37 within which the wires are enclosed, a coil spring 38 being provided around said plunger to normally hold the switch member 36 out of engagement with the contact points 12 and 12*".

The operation of the device is as follows: Assuming that the clock 2 registers about three minutes of two as shown in Fig. 1 and the driver desires to park the machine for about an hour the time mechanism will be set for 3:00 oclock as shown in said figure and the plunger 23 will be depressed as shown in Fig. 3, the spring pressed pawl 29 engaging the notch 28 in said plunger and preventing the plunger from being raised.

As the plunger 23 is depressed the insulated head 27 thereon will engage the arms 21 and 21" moving said arms downwardly out of contact with each other breaking the circuit from the battery and magneto to the spark plugs while at the same time the plunger 35 will be engaged by said head 27 and moved downwardly, moving the switch member 36 into engagement with the contact points 12 and 12 closing the circuit from the batteries to the solenoid, energizing said solenoid and drawing the armature 14 thereof inwardly against the tension of the spring 1% closing the valve 17 in the inlet manifold.

The ignition will thus be cut oil and the supply of gas to the cylinders will be shut off and the parts will remain locked in this position until the predetermined time for which the time mechanism is set at which time the time or alarm mechanism will opcrate in the usual manner rotating the disk 33 in the direction of the arrow shown in Fig. 3, the tappet 32 thereon engaging the tail 31 of the spring pressed pawl 29 moving said pawl downwardly out oi. the notch and allowing the spring 26 to throw the plunger 23 up into the normal position, the springs 22 raising the switch arms 21 into engagement with each other while the spring 38 willraise the plunger 35 moving the switch member 36 out of engagement with the contact points 12 and 12, closing the circuit from the battery and magneto to the spark plugs and opening the circuit to the solenoid, the spring 1 h moving the armature thereof into the position shown in Fig. 5 opening the valve 17 and allowing the admission of gas to the cylinders.

I claim:

1. In an electric circuit, a switch comprising a pair of spring pressed arms, a. second switch including aspring pressed switch member, a plunger provided with an insulated head and arranged to be depressed to engagesaid spring pressed arms and said spring pressed switch member to operate both of said switches, means for holding the plunger in the depressed position and a time operated mechanism arranged to engage said means to release the plunger at a predetermined time.

2. In an electric circuit, a pair of switches, means for holding one switch normally open and means for holding the other switch normally closed, a plunger arranged to be depressed to close the normally open switch and open the normally closed switch, a spring pressed pawl arranged to hold the plunger in the depressed position and a time operated mechanism arranged to engage said pawl to release the plunger at a predetermined time.

In testimony that I claim the above, I have hereunto subscribed my name.

ARTHUR WV. LYDA.
