WINDOW CONTROLLER I Filed May 8, 1939. 4 Sheets-Sheet 4 Inventor Patented Feb. 18, 1941 UNITED STATES PATENT OFFICE 4 Claims.

This invention appertains to new and useful improvements in means for controlling windows such as the automobile window adjacent the drivers seat, with the principal object in view of per- 5 mitting convenient and eifortless operation of the window when the driver is required to give traific signals especially in inclement weather.

Another important object of the invention is to provide an automobile window control which is power operated and which requires only switch actuation on the part of the driver to effect the elevating or lowering movements of the window to the desired extent.

These and other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings Figure 1 represents a fragmentary vertical sectional view through a door showing in side 20 elevation the control mechanism.

Figure 7 is a side elevational view of the assembly shown in Figure 6.

Figure 8 is a, diagrammatic view disclosing the electrical connections between the electrical devices involved.

Figure 9 is a fragmentary longitudinal sectional view through the door jamb shaft jaw.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 8 that numeral 5 generally refers to the controller for regulating the duration of operation of the motor generally referred to by numeral 6.

Numeral I represents the switch which is associatcd with the controller 5 and which is in circuit with the field 8 of the motor 6.

Numeral 9 represents the switch which is au tomatically operated by the window-operating beam, while numeral I generally refers to the reversing switch. A door jamb-controlled switch generally referred to by numeral H in the lead |2 from the battery or other source of current I3.

As shown in Figure 1 the motor 6 is suitably mounted, preferably in the cowl portion of the automobile and has its shaft l4 disposed into the jamb wall l opposed to the vertical jamb portion |6 of the hinged edge of the door IT. The shaft M has the socket head l8, the surface of the socket being formed with a channel for receiving the rib I9 on the ball section which is carried by the plunger 2| operative in the barrel 22. The outer end of the barrel is flanged as at 23 to serve as an abutment for the circumferential shoulder 24 on the plunger 2|. -When the door |l is open the ball 20 simply rotates in the socket head |8 as the spring 25 forces the plunger 2| outwardly. A shaft 26 having the fixed collar 21 thereon in the barrel 22 hasthe squared portion 28 in the barrel slidably disposed in the squared opening 29 of the plunger 2|. The shaft 26 at its rear end is equipped with the bevel gear 30 which meshes with the large bevel gear 3|. This gear 3| is suitably mounted and carries with it the pinion 32 which meshes with'the semi-circular gear 33 on the shaft 34.

Extending in alignment with the straight side of the gear 33 is the shank 34 which at its outer end has the T-shaped' member 35 swingably mounted thereon on the fulcrum 36.

Asshown in Figure 1, the window glass 31 has the base strip 38 from which depends the flange 39 having the longitudinal slot 40 therein and this slot receives the stud 4| which projects from the upper end of the T-arm 35.

The T-member 35 which is substantially inverted in use has the finger protrusion 43 which operates between the two lugs 44-44 on the shank 34, these lugs serving as stops. To afford a yieldable connection between the arm 35 and the shank 34, coiled, tension springs 45 and 46 extend between the outer ends of the swing members 4'l -4'| and anchors 48 on the shank 34, the spring 46 being substantially stronger than the spring45.

As substantially shown in Figures 1, 2 and 3, a lever 49 is rockably supported as at 50 on the gear '33 and has the head 5| of insulation to which the arcuate strip 52 of current-conductive material is secured. The lower end of the lever 43 terminates in the circular head 53 which has an outwardly extending knob 54, and a compressible spring 55 is interposed between. the lever ,49 and the gear 33 to normally maintain the head 53 urged outwardly and the free end of the lever 49 urged inwardly toward the shank'34 with its slottedguide 56 receiving and retaining the elongated strip spring 51 disposed in the V-cut ,of t he boss 58. One end of this strip spring 51' is anchored and insulated as at 59 while its opposite. end isoperative between the lugs Bil-S0 on the ends of the plate BI and normally operate within the confines of the V-cut of the boss 58. The free end of the spring 51 carries the contact 62 properly insulated from the spring 51 and in wiping engagement with the strip 52.

A spring is convoluted on the shaft 34 that has one end secured to the shaft and the other end secured to the bracket 65, this spring being denoted by numeral 64.

t can also be seen that the gear 33 is secured to the shaft 64 and that the adjacent outer end of the shaft has the lateral arm 96 from which extends the rod 61 to the lug 68 of the switch 1. A

(See Figures 1 and 8.)

The switch 1 consists of the disk 69 having the pin 10 extending laterally therefrom. This pin 10 operates between the two contact arms "II and 12 which are covered with the conductor strips 13 and 14 respectively. These strips H and 12 of insulation are mounted on the strip springs 15 and it respectively, which as shown in Figures 6 and 7, are disposed at opposite sides of the stump 11 which rises from the bight portion 18 of the U-shaped frame which includes the front and back legs 19 and 80. The lower ends of these springs 15 and 16 are insulated from the stump 11 and additional blocks I, 82, 83, and 84 are secured together with the springs 15 and 16 and the stump 11 through the use of bolts 85 to properly mount the switch elements of the reversing switch I0. The switch elements consist of the strip springs 86, 81 and 83 which carry at their upper ends the cross-members 89, 90 and 9| of insulation. The strip 9i carries the contacts 92 and 93, while the strip 89 carries the contacts 94 and 95. The intermediate contact strip 90 carries the contacts 96 and 91.

This reversing switch I0 is operated by the duration and reversing switch assembly generally referred to by numeral which consists of the disk 98 having the tortious groove 99 on the front side thereof and in this groove operates the stud I00 of the rockable lever IOI which is fulcrumed as at I02 on the bracket I03 carried by the leg 19. As shown in Figure 8 the lower end of the arm IOI has the laterally disposed and bifurcated finger I04 which receives the upper end portion of the spring 81 of the reversingswitch I0.

The upper portion a of the groove 99 serves to control the window-lifting and lowering mechanism in one direction while the portion 1) controls the apparatus in the opposite direction.

A portion of the periphery of the disk 98 has the conductor strip I05 secured thereto and against this rides the brush I06. The brush I06 is insulated from the bracket I03 by the block I01 of insulation. The upper end of the conductor strip I05 has the connection I08 to the contact pin I09 which projects rearwardly from the disk '98 and is interposed between the upper portions of the arms 1| and 12 as shown in Figure l, on the inside wall of the door I1 there is a segmental dial IIO through which a shaft extends and this shaft carries at the drivers end the handle III and adjacent its inner end the short arm II2 from which extends the connecting rod II3 to the lug I I4 on the disk 98. Thus by actuating the handle I I I to the desired degree, the dial I I0 can be provided with suitable graduations, the disk 98 will be adjusted to a predetermined position with the studs I00 located at a particular position either in the groove a or the groove b which of course determines whether the contacts 96 and 91 are to be engaged with the contacts 92 and93 or 94. and 95, for regulating the motor 6 in one directionor the other. Obviously when the reversing switch I0 is in fact closed, the mechanism starts in operation and will continue until actuation of the rod 61 moves the disk 69 so that the pin 10 will disengage the corresponding arm H or 12 from the contact pin I09, thus breaking the circuit.

The mechanism shown in Figure 2 is to take care of any undue strain on the mechanism. In the event the window 31 becomes jammed, the spring 46, or the spring 45 will yield and the T-arm 35 will break or swing on the shank 34 so that the spring 51 moves out of the V-cut of the boss 58 and over the end thereof and it requires actuation of the lever 49 before this spring 51 can be restored. Obviously when the spring 51 rides over one end of the boss 58 the contact 62 is disengaged and held disengaged from the contact strip 52.

The switch II is of simple design, the same simply consisting of a spring-pressed pin operative against the switch blade so that the switch is only closed when the door is closed and will automatically open to break the circuit when the door is in open position.
