This invention relates to an indicator adapted to show the time which has elapsed since a machine has ceased operation, for example, since a conveyance has come to rest. 5 For convenience, it is referred to as a parking clock since one of its most useful applications is as an indicator of the time during which a vehicle has been parked. The principal object of the invention is the provision of elapsed time indicating means adapted to be mounted upon a device capable of movement or operation and actuated by potential power means to indicate the time during which the device is not in motion or According to the invention, the elapsed time indicating means is actuated by power means whereof the potential is adapted to be restored during the operation of the device, means being provided to return the elapsed time indicating means and to restore the potential in the power means dependent upon the movement of the machine which means are-retained in operative position during the movement of the said 7 device.

It is also an object of the invention to provide electro-niagnetic devices for restoring the potential in the power means and returning the elapsed time indicating means to so initial position, dependent upon a source of electrical energy which .is disconnected during the operating movement of the device although the said means are mechanically retained in operative position.

These and other objects of the invention,

and the means for their attainment will'be more apparent from the followingdetailed description taken in connection with the accompanying drawings illustrating a preferred embodiment of the invention in which:

Figure 13 is a view showing a wiring diagram illustrating the operation of the device.

In general the invention involves a dial 14 indicating divisions of time in the illustrated embodiment, six in number, over which one or more pointers or

hands

15 and 16 are propelled to indicate elapsed time, that is time which elapses between two events, such as the stopping and starting again of a conveyance, machine or device of any character capable of movement or operation. The hands are propelled by what may be broadly termed clock mechanism since the measurement of time during which the machine is at rest is made in units of standard time. Also combined in the indicator is standard time indicating means, hereafter referred to as a time piece, suchas is illustrated by the dial 17 and the hour and minute hands, 18 and 19, respectively. In the illustrated embodiment, the

potential or power means for actuating the clock mechanism takes the form of a main spring 20.

The time piece 17-19 functions constantly to give the time of day, but the elapsed time indicating means 1416 functions only when the machine or other device upon which the indicator is mounted is not in operation or in motion. So soon as the machine stops, suitable devices hereinafter to be described are caused to release the elapsed-

time indicating pointers

15, 16 which are then caused, by the main spring 20, to travel over the elapsed time indicating dial 14 and their travel is continued until the machine starts,

- when the progress of the

hands

15, 16 is arrested and they are returned, to initial position, indicated by the ordinal zero, in F igure 1, by a movement which simultaneously restores the potential in power spring 20. In the illustrated embodiment the elapsed time indicating dial is shown as divided into only six subdivisions to represent six hours of inactivity of the device upon which the indiester is mounted. Obviously, any number of hours may be indicated and the mechanism adjusted to operate for such period, but only six hours parking time is provided for in the illustrated embodiment as all that is required from practical considerations, as municipalities which find it necessary to restrict the parking of vehicles do so for periods of less than the six hours, or not at all. The instrumentalities availed of to effect this movement are shown as electro-magnetic devices which are energized by any convenient source of electrical energy indicated conventionally at 22 in Figure 13. This energization is controlled by devices responsive to movement of the device when in operation,

specifically the swaying of a conveyance.

Referring particularly to Figure 4, the indicator mechanism includes what may be termed a center shaft 24 which is rotated in one direction, to wit, a clockwise direction by the main spring 20 and in turn is operably connected by trains of gears, to be described, to the respective indicating

hands

15, 16 and 18, 19 of the parkin and

time clocks

14 and 17 respectively. he center shaft is rotated in the opposite direction by the electro-magnetic devices to wind the main spring and return the parking hands to initial position. A ball clutch 26 between the center shaft 24 and the standard time indicating mechanism 1719 and escapement mechanism 27 permits the center shaft 24 to drive the

parking clock hands

15, 16 and the standard

time indicating hands

18, 19 in clockwise direction and operates the escape ment 27 but uncouples the time clock and escapement when rotated in the opposite direction, i. e. in a counter-clockwise direction, by the electro-magnetic devices. The main spring 20 is mounted on an arbor 28 journaled at its ends in the front and rear clock frame members 30 and 31- and is secured at one end to a pin 33 Figures 4 and 5 and at its other end to the arbor 28 to rotate the'arbor. It is positioned between a disc 35 freely rotatable upon the arbor 28 and carrying a flange 36 serving to space the disc from the rear frame 31 and a gear 37 fixed on the arbor 28 by which the center shaft 24 is rotated through the pinion 38 with which the gear meshes. The gear 37 and pinion 38 form mechanical means to drive the shaft section 24 from the arbor or another shaft section 28. The gear 37 and pinion 38 may alsobe called a driving connection between the arbor 28 and the shaft 24.

The pinion 38 is carried on the plate 39 fastened upon an inner member 26 of a ball clutch indicated as a whole at 40 so that clockwise rotation of the pinion 38 by the gear 37 turning in a counter-clockwise direction by the unwinding of the spring 20 causes engagement through balls 41 of an outer clutch member 42 freely rotatable on a hub carried by the inner member 26 of the ing the gear 45 with the escapement 27. The

arbor 49 carries rigidly therewith a gear 50 meshing with a pinion 51 rigidly mounted on the arbor 52 with the gear 53 which in turn meshes with a pinion 54 mounted upon an arbor 55 carrying the toothed wheel 56 forming one of the elements of the escapement 27. The escapement may take any form, that illustrated being a common form of escapement used in clocks and which in usual fashion controls the rotation of the center shaft 24 and hence the unwinding of the spring 20 in synchronism with standard periods of time.

The pinion 46 on the inner clutch member 26 drives the elapsed time hour hand 16 at a speed proportionately slower than the minute hand as will be understood. This hour hand 16 is carried upon a sleeve or hollow shaft 60 concentric with the end of shaft 24 and is rotated by the pinion 46 meshing with a gear 61 fixed upon one end of an axle journaled in the front frame 30- and carrying upon its front end in front of the front frame 30 a pinion 62 which meshes with a gear 63 carried on the hollow shaft 60. By suitably proportioning the

pinions

46, 62 and

gears

61 and 63 the hour hand 16 may be propelled over the face of dial 14 at a rate to indicate hours of parking time while the minute hand 15 is directly propelled by the .shaft 24 and hence by the mainspring 20 whereof the rate. of unwinding is controlled by the escapement at a rate to indicate hours of parking time.

The standard time indicating hands, to wit, the minute hand 18 and the hour hand 19 are mounted upon what ma be calleda clock shaft 65 also journaled in t e front and rear frame members 30and 31, the minutehand 18 being directly carried on the end of the shaft and the hour hand 19 being carried upon a sleeve or hollow shaft 66 concentric with the clock shaft 65.

The clock shaft 65 is rotated by the main spring 20 by a train of gears now to be tie-- scribed. An idler gear 68 pivotally mounted '-on the front frame member 30 meshes with and is rotated by the gear 45 carried with the outer ball clutch member 42 and in turn meshes witha gear. 69 loose on the shaft 65 but capable of frictionally driving the same by a spring clutch connection therewith consisting of a coil spring 70 disposed between anabutment 71 fastened on theshaft 65 and a collar 72 which is loosely mounted on the clock shaft 65 and which tends to press the collar against a flange 73 formed on or carried with the gear 69. In the illustrated embodiment this flange is shown as a pinion since stock clock parts may be conveniently used in the assembly of the indicator. Thus rotation of the center shaft 24 under the action of spring 20 causes the rotation ofthe gear 69 and with it the clock shaft '65.

Also mounted on the clock shaft'and preferably integral with the gear 69 is a pinion 75 adapted to mesh with a gear 76 fixed on an axle journa'led in the front frame member 30 and carrying on its other end in front of the front frame a pinion 78 which meshes with and drives a gear 79 carried with the sleeve 66.

By suitably proportioning the train of gears just described in a manner well understood the

hands

18, 19 are propelled over the face-17 of the clock to indicate standard periods of time, to wit, hours and minutes.

Thus the elapsed time indicat0rs,'15, 16, are driven from and the clock hands 18, 19 move in unison with gear 45 carried with the outer clutch member 42 which i's-rotatable on the hub of the inner member 26. Therotation of'gear 45 is thus controlled by the escapement 27 and its rotation is permitted in only one direction to wit, clockwise, by the ball clutch. The rewinding of the spring and hence the storing of the potential in the power means, which is the spring, is effected by turning the center shaft in a counter clockwise direction during which operation the escapement, and thestandard time or clock gearing are momentarily unclutched from the center shaft. The center shaft 24 is turned in counter clockwise direction' by electro-ma etic devices, now to be described w ich, because of their construction, effect the rewindin by a step by step movement. Each step 0 rewinding is of extremely short duration, so that the momentumof the escapement is enabled to. continue the operation of the standard time mechanism, without retardation or variation due to the interaction of the escapement v gearing and the standard timeclock gearin i I Tieference will now be had to Figures 7 through 10 and Figure 13 form understand- 7 removably secured to the forward end of the armature shaft 81 and the outer member 83 is carried for rotation with the end of the center shaft 24 by a joint capable of relative movement to compensate for inequalities in alignment of the two shafts. The end of shaft 24 is rectangular as at 29 and is disposed within a slot 86 formed in a he: 1 87 carried by the clutch member 83. A helical spring 25 surrounds the head 87 between the abutment 85 and the clutch member 83 to contribute to the alignment of the parts. The clutch is illustrated in detail in Figure 11 from which it will be understood that rotation of the armature shaft in a counter clockwise direction will turn with it the nter shaft 24 and thereby wind the main 17 as will be understood, when shaft 81 is rotated in clockwise direction as viewed in Figure 11 for apurpose which will be more apparent hereafter, as it is desirable that shaft 24 be free for rotation in the operation of the clock mechanism. The balls 88 are therefore held in a neutral position by forks 89 integral with the rocking lever 84 fulcrumed on the hub 44 of the clutch member 82. A spring 102 carried on the frame member 105 retards said lever 84 when returning to its neutral position, its stopping point being assuredor effected by a spring 107.

The rear end of armature shaft 81 carries what may be describedv as a two pole armature 90 rotatable within the diametrically opposite pole pieces 91 and forming with the armature what is in effect an electric motor.

Referring particularly to Figure 13, current from a source of electrical energy 22, say a storage battery, flows by the conductor 101, to the coils 103, of the field magnet 92 for the motor pole pieces 91. From the field magnet the current returns to the battery 22 through circuit closing devices operable automatically dependent upon the movement or operation of the device on which the indicator is mounted.

Assuming, for the sake of convenience in description, that the indicator or'parking clock is mounted upon a motor vehicle, a vibrator or trembler 110 in the form of one arm of a bell crank lever 102 is pivotally mounted as at 111 upon a transverse frame member 105 and is adapted to be brought into contact with a pair ofspaced pole pieces 112 by the swaying of the vehicle. These pole pieces 112 are electromagnets electrically connected, by the conductor 113, with the positive terminal of the battery 22 and through a conductor 114 with a pair of normally closed

contacts

115, 116, conductor 117, electromagnets 112, trembler 110, and conductor 118 to the ground G. Thus when the trembler 110 contacts with the pole piece, the circuit is completed which energizes electromagnets 112 and they retain the trembler in circuit closing position to energize the field of the motor so long as

contacts

115 and 116 are closed.

Contact 115 is resiliently carried upon an insulating block 119 secured to one arm of a lever 104 pivoted as at 124 upon frame member 105 said lever 104 being normally retained by the spring 120 in such position that the

contacts

115, 116 are normally closed. As a practical expedient conductor 114 is connected with a resilient leaf .121 which is always in wiping contact with a similar resilient leaf 122 carried on the pivoted block 119 in electrical connection with the resilient arm 123 carrying the contact 115 so that regardless of the position of the block-119 as it pivots about the fulcrum 124 an electrical connection will always be assured through the

contacts

121, 122.

The closing of the

contacts

110 and 112 also completes the circuit including the battery and the motor and hence energizes the motor field since coil 103 of the field magnet is in circuit with electrical conductors 106, and

contacts

108, 109 which are normally closed.

Contact 109 is carried upon a resilient frame 130 mounted upon a metallic rocking member 131 pivoted at 137 on insulator 134 and operatively connected by bar 132 through a conductor 133 with the contact 121 and from thence to the ground as hereinbefore described.

Thus, so soon as the trembler 110 makes an electrical contact with the pole pieces 112. the field magnet 92 is energized together with the armature 90, the winding of which is energized by .a shunt connection between

conductors

101, 106. The armature 90 is thereupon caused to rotate immediately in the direction indicated by the arrow X about the aXis of the armature shaft 81 and thereby turning the armature shaft in a counter clockwise direction to wind the spring as previously described. That is, during the rotation of the armature shaft 81 in counter clockwise direction, the center shaft 24 is clutched to the armature shaft 81 and is rotated therewith to'wind the mainspring 20 through the

gearing

37 and 38. This rotation of the shaft 81 takes place through only a relatively small angle and is extremely rapid in order to permit the momentum of the escapement to continue the operation of the standard time mechanism without interruption, the escapement and standard time clock mechanism being disconnected by the .by contacts with one arm 136 of the rocking member 131 rotating it about its pivot 137 to carry the contact 109 away from the contact 108 and break the circuit including the motor field 103 and deenergize the motor pole pieces. A spring 139' immediately returns the armature'to initial position as shown in Figure 9 bringing the pin 135 in contact with the other arm 140 of the rocking member 131 to rock that member about the pivot 137 and carry the contact 109 again in contact with contact 108 to close the circuit and permit the reenergization of the motor which effects another rotation of the armature shaft in counter clockwise direction, as before.

During the movement of the armature under the influence of the spring 139, i. e. the

return-ing movement, the armature shaft 81 is disconnected orunclutched from the cen-' ter shaft 24 by the ball coupling so that the spring remains wound by the partial revolution of the armature shaft 81 just described. During the return movement of the armature shaft 81 the clutch 26 engages with the es capement, sothere is no backlash and this

indicators

15, 16 to the initial or zero po-- sition by a step by step movement coinciding with the step by step winding of the main spring 20 so that when the mainspring 20 is fully wound up the elapsed time hands 15, 16 are at zero or initial position.

The alternate energization and deenergization of the motor continues until the step" by step rotation of the main spring arbor 28; completely winds the main spring' As we viewed from Fig. 13, main spring arbor 28 rotates in a clockwise direction when rewinding which brings a cam 142 into contact with a shoulder 143 carried upon the arm 144 of the bell crank forming the trembler 110 and serves to depress the arm 144 so that the contact 110 is retained in circuit closing position to keep the arm 144 rigid and mot onless until such time as the spring requires further winding.

A portion of the cam 142 or'a second cam 141 also carried on the end of the power spring arbor 28 also depresses, at about the same time, an arm 145 of the pivoted lever 104 heretobefore referred to as carrying the pivoted block 119 rotating the block about its pivot 124 against the action of the spring 120 to open the

contacts

115, 116 and thereby interrupt the several circuits including battery 22 so that subsequent or continued vi- Of course during the further or continued operation of the conveyance the standard time clock continues to function thereby necessitating the unwinding of the main spring 20 to some extent. This unwinding of the main spring however, results in the rotation of the main spring arbor 28 to bring the cams 141, 142-out of contact with the

arms

144, 145 thereby permitting the

contacts

115, 116 to close quickly under the influence of the spring 120 and the trembler 110 to operate to energize the motor.and rewind th spring as described.

' The parts are so proportioned that when the main spring 20 is unwound to the point where winding it again will just return

pointers

15, 16 to zero position, the cam 142 on the main springarbor 28 comes around in a contra-clockwise rotation as viewed in Fig. 13 and contacts with the other face of the projection 143 on the bellcrank 102 to 1'0- tate the bell crank to again close contacts 110,-

112 to reenergize the motor and wind up spring 20. It will be noted that arm 104 -1s cut away or recessed to such an extent that cam 141 does not contact with arm 104 and therefore the spring 120 is effective to hold the

contacts

115, 116 closed. This occurs after six hours of operation of the elapsed time indicating mechanism. Six hours operation has been adapted arbitrarily as it is unlikely that municipal parking ordinances will attempt to regulate parking in situatlons where it is unobjectionable for that length of time,

From an inspection of Figure 3 it will be, observed that what may be termed broadly, clock mechanism is carried between a pair of

frame members

30, 31 spaced by posts-146 and that the electro magnetic devices are carried by the frame member 105 from'posts 147,

the frame member 105 being suitably spaced from but carried rigidly on the clock mechanism frame by posts 148. Thus a compact structure is provided which is interconnected as a unit and carries, by the posts 149, the face 15 upon which the

dials

14, 17 are depicted.- The entire structure is thus conveniently supported within a casing or housing 151 which may be carried say on the vehicle for convenient observation and reference. Obviously the supporting

frame

30, 31, 105 moves with the device upon which it is mounted and for the purposes of description the frame may be looked upbn as'the device, the movement of which affects operation of the mechanism although it will be obvious that by the term device any instrumentality is intended to be covered.

It is thought that the operation of the indicator is apparent from the foregoing description. It will be observed that the main spring 20 is wound by a periodic turn of the center shaft 24 in one direction of rotation by what is in effect a motor and that this periodic turn of the center shaft 24 returns the elapsed

time indicators

15, 16 to initial position. While the vehicle is in operation this vibration or swaying serves to close the electrical circuit which energizes the motor and the rotation thereof is transmitted to the center shaft by a ball clutch to rotate the same. Movement of the motor armature through the predetermined angle serves to interrupt the current energizing the pole pieces of the motor and permits a spring to return the armature to initial position when the circuit is again established and the armature again turned to cause a further turning of the center shaft 24. 7
