8 Claims.

This invention relates to an automotive vehicle window regulating system, and is particularly directed to automatic means for controlling the windows of such vehicles.

An object -of the present invention is to utilize the starting motorof the vehicle as a power source for driving iluid power means for opening.

and closing the windows, controllable by means located within easy accessof the operator, or other occupant, of the vehicle.

Another object is to utilize a starting motor provided with the so-called Bendix drive for operating fluid pump means associated therewith to actuate means coupled to the windows for moving the latter, means being Provided to ren- `der thestarting motor effective to perform the dual operations of driving the fluid pump and cranking the vehicle engine. l

A. further object is to provide the starting motor with a novel remotely controlled starter drive of this type adapted to be selectively latched` or unlatched to permit the ystarting motor to be 4used to drive a uid pump to operate the windows orto crankthe engine, or both.

Further objects of the invention will appear as the description proceeds in connection with the accompanying drawing, in which:

Figure 1 is a diagrammatic view of an embodimentvof the present invention, only one of the plurality of windows to be operated being illus-K trated; and FigurelZ is an enlarged fragmentary sectional -nisms illustrating details of the present invention. Figure 1 illustrates somewhat iragmentarily a portion of an automobile indicated generally at- I, and shown asincluding a dash board I4. iioor I5 and toe board I 6. One of the doors It cylinder al connected te the lower end ef-nni; ze, and within which is positioned solenoid 'controlled iiuid `actuated means` to raise and lower the cylinder 3l and thus the window l2i) through the rod 28 and associated linkage. Fluid is supplied to and withdrawn from the cylinder through a conduit 32 .connected to a supply pipe 33 leading from a suitable pump 35.

As diagrammatically illustrated in Figure `1,

'means are shown for supplying power to the cylinder 3|, as are means for controlling the supplyv means, and means remote therefrom for' energizing or rendering effective the entire system. The powermeans has been shown as a hydraulic system'including a reservoir 3l which need not be a separate reservoir, as the use of the vehicles brake-systemreservoir or the crank cas'e of the engine is contemplated as a source of iluid or oil for the present system.

A pump 35,*of desired characteristicsis an essential element of the presentinvention, and,

" `although the type of fluid pump used is irnmateriaLthe means for operating such a pump forms an important part of vthis invention. The pump 351s, ther/efore, illustrated as directly asso- 'ciated with a conventional starting motor 4U, and as'provided with a fluid supply duct 4I in communication with the reservoir 31. and the vpipe or conduit 33, suitably branched into any desired number of branches, herein illustrated as four pipes 43, 44. 45 and 46, each of which is connected lview'of the starter drive and associated mecha- Windows ofthe'vehlcle (not shown).

ofv the vehicle is shown as including a window opening I9 adapted to be closed by`means of a glass or other transparency 20. Mounted interiorly of the door I8 and below the glass 2Il` is the window operating means indicated generally at 22, and including a pair of levers 23 and 24 pivotally connected intermediate their ends, and each having oneendpivoted respectively to a glass supporting channel 25 and a support 26 carried bythe door. Lever 23 is connected by a rod or link 28 for operation by a power unit, indicated generally at 30. The power unit per se forms no part of the presentlinventionfbut is Iincludedin the subject matter of a co-pending application of John 'B. Parsons yand Burton S. Floraday, Serial No. 275,207, led May 23, 1939.

to a power unit coupled to and capable of operating a window of the vehicle. As illustrated, the pipe 43 leads to conduit 32 and thus to the unit 30, associated with Window 20 in the door I8, and

it will be understood thatthe other pipes lead to similar units assciated with three other in detail inFigure 2. Motor 40 includes an armature 53 having a shaft 54, one end, loi. which is supported in a suitable bearing 55. The shaft 54 is provided with an extension 56, the outer end of. which is supported ina bearing 51 carried by a housing 58, which partially encloses the The power unit 30 comprises a reeiproeable 65 drive mechanism. The drive mechanism is of the type wherein a pinion gear 80 is .rotatable with and with respect to the shaft extension 56, as well as being movable longitudinally thereof into engagement with a flywheel or other gear 62 of the engine. Pinion 60 is internally threaded at 63 for threaded engagement with a sleeve 64 xed against longitudinal movement on the armature shaft and having limited rotary movement with respect thereto through the medium .of a starter spring 65 having one end secured to the sleeve 64 and the other Aend secured to a collar 61 pinned or otherwise fixed to the shaft 54.

Operation of the starter drive thus far described is in accordance with well known practice. However, in order to adapt the starting motor for use in operating the pump 35 independently of its use to crank the engine,.latch or lock means mally disposed in a transverse bore 151m the extension 56 and has a portion engaging a"`shou1 der 11 on the pinion 60, thereby holding the pinion against longitudinal movement.

A lever 80 suitably pivoted to the bell housing 8| of the engine is adapted to be rocked into engagement with the outer end of pin 69 to'release the pinion 60. The lever 80 may be remotely controlled from the dash I4, or other convenient part of the vehicle, by a Bowden wire 83 supported in a suitable sheath 84'and having a control button 85 at one end thereof. 'I'he lever 80 is also arranged to close a switch 81 mounted in the path of thelever. Switch 81 comprises spaced contacts'88, 89 and 9| adapted'to be bridged bya contact bar 90 movable into engagement therewith in response to rocking movement of lever 80. The arrangement is such that pinion 60 is released priorl to the closing of switch 81 by the lever 80. Thus it will be noted that the motor 40 ispapable of being energized by means of theswitch 81, which is-connected into an electrical circuit now to be described.

Referring again to Figure 1, the circuit' illustrated includes the starting motor energizing circuit, including an electro-responsive switch, as wellas a circuitA to a starting motor control switch so that the motor may be simultaneously or conjointly operated for window actuation and starting the engine, or each operation may be independently performed. Associated with the starter motor 40 is a solenoid actuated switch-indicated at 92.

The switch 92 includes a pair of contacts 93 .and 94, whichmay be closed electrically 'by energization of a solenoid coil indicated by the reference numeral 95 and which moves a plunger carried contact bar 96 to bridge the contacts. Energization of the solenoid causes current to ow to the starting motor to energize the same and drive the pump 35. Obviously, if the motor 40 is to be used to supply power to operate the windows of the vehicle, additional -means are re- `quired to energize the motor so that the driving In accordance with standard automotive practice, a single Wire system is used to control the organization of the present invention, all circuits leading from a battery 98 to a suitable ground. A switch is mountedfor convenient manipulation by the operator of the vehicle as on the dash I4, and may be of any suitable construction, preferably provided with four spaced contacts or binding posts to which certain of the wires of the present circuit are connected. The switch mechanism may be enclosed in a suitable box within which are carried 'a plurality of independently operable elements |0| for controlling respectively each of the windows of the vehicle. Each of the switch elements is preferably arranged so that it has a neutral position from which the switch is moved upwardly to energize a circuit to close the window and downwardly to energize a circuit to open the window. Thus the element |0| is arranged to interconnect a plurality of contact elements |02, |03, |04 and |05, which are connected into the circuit in the following manner. Contact |02 is connected by a lead |06 to one side of the solenoid coil 95, the other side of the solenoid being connected by lead |01 to a suitable ground. Contact |03 is connected to one side of the solenoid coil in unit by a lead |09, it being noted that four leads, one for each window power unit, are illustratedas being connected to the contact |03, which is Vpreferably a four-part contact or four separate contacts. The circuit is completed by suitably grounding the other end of the coil. Contact |04 is connected to a switch I0 in turn connected to the battery 98 by means of a lead Switch 0 may, if desired, be a conventional ignition or accessory switch of the vehicle, or a combined ignition and ,accessory switch. Contact |05 is connected by a lead H3 to one side of the coil 50 mounted on the flow control valve 48, which coil is grounded at ||4.

From the description thus far, it is to be noted that the electrical circuit is energizable to operate the motor 40 through switch 92. Accordingly, by manipulating switch element |0| preferpreferably adapted to bridge contacts |02, |03 and 1 |04 when in its uppermost position, and when such contacts are thus connected current will flow from battery 98 through lead switch ||0, switch |00, lead |06 and to solenoid coil 95 to energize the solenoid and close switch 92, and thus energize motor 40. At the same time the solenoid in the unit 30 is energized through lead |09, which is connected to the battery upon manipulation of element |0|. Unit 30 is arranged'so that fluid will pass into or out of the cylinder 3| when its solenoid is energized. Valve 48 is arranged to permit uidto be pumped out of the unit 30 when solenoid 50 is energized and into unit 30 when the solenoid is not energized. Thus, in this instance the coil 50 is not connected onto the circuit and not energized, so that fluid will be pumped into unit 30, and thus urge the window toward closed position.

When itis desired to open the window, switch element |0| is moved downwardly, in which posiconnection between the starter drive and the engine flywheel will not be established at times when it is desired to regulate the windows.

tion all four ,contacts |02, |03, |04 and |05 are bridged and 4lead I|3 is additionally supplied with current to energize the solenoid 50 to move valve 48 into position permit pump 35 to withdraw iiuid from the unit 30 and thus lower or open the window. The foregoing describes the operation when the motor 40 is energized and the plunger'69 is in itsouter position to latch the pinion to the shaft extension 58 and thus` prevent the starter from cranking the engine.

To use motor 48 as a starting motor, either A independently of or concurrently with the operation of the window regulating mechanism, the motor is energized upon closing of switch 81. Contact 88 is connected to the battery 88 by means of a lead H5, while contact 8| is connected to one side of the solenoid lcoil 85 by a lead Ill. Thus, closing the switch 81 energizes the solenoid 95 to close the motor circuit to energize the motor 48. At the same' time, contact 88v receives energy fromA the battery, which is cona ducted through a lead IIB 'to one side of the flow control valve solenoid 58 to energize the latter.

` window during the period in which the motor is cranking the engine, as solenoid 58 is always energized upon energization` of motor through the medium of switch 81.

From the foregoing description it will be apparent that means are provided for utilizing a single power source for the dual purpose of operating the vehicle windows aswell as cranking the engine, means also being provided for preventing actuation of a normally automatic starter drive said window, a motor, .a drive mechanism for cranking the engine coupled to said motor, a

. motor driven pump for supplying iluid to said with said drivejmechanism to render said drive when it is desired to utilize the starting motor only to operate the Window regulating means. It will also be noted that the arrangement is such that should the window control switch be actuated to,close the Window and the starter switch be concurrently actuated, the window operating means is temporarily rendered ineffective to close the window until the manual switch 8l is opened, coil 58 deenergized and valve 48 positioned to permit fluid to be pumped to the' pended claims.
