WINDOW REGULATOR gwoentoc (lamllceld ffm Patented Mar. 18, 1930 UNITED STATES PATENT OFFIC CLARENCE E. J'EFFERS, OF YORK, PENNSYLVANIA, ASSIGNOR TO MARTIN-PARRY CORPORATION, OF YORK, PENNSYLVANIA, A CORPORATION OF DELAWARE WINDOW REGULATOR Application filed April 9,

The invention relates to improvements in means for supporting and adjusting the position of glass panels or windows in automobile bodies.

It is an object of the invention to provide a simple mechanism having a panel supporting element and a control lever therefor per mitting the window panel or pane to be readily adjusted and retained in its various positions of adjustment.

More specifically, the invention embodies an improved form of latch element having associated parts cooperating with a window pane and a rack for holding the pane in its adjusted position, and a manually operated control lever associated therewith and controlling said latch, said control lever also serving to facilitate the raising or lowering of the pane or panel.

In the drawings Figure 1 illustrates a view of a door looking at the inside thereof.

Figure 2 is a sectional view on line 11 of Figure 1.

' Figure 3 is a view of the control attached to a panel.

Figures 4 and 5 are sectional views; and,

Figure 6 is a detail view of the rocking latch.

Referring now more particularly to the drawings wherein like reference characters indicate corresponding parts, the numeral 1 designates the door of a vehicle body, which in this illustration is an automobile body of the commercial type. This door has therein a well 2 into which the window panel 3 is lowered when ventilation is desiree.

The window panel embodies the usual glass pane sliding in suitable guiding recesses 4 in the door, with the lower edge thereof encircled by metallic plates 5.

The well 2 of the door receives the vertical rack bar 6 which is retained in position in any suitable manner. This rack bar lies substantially in alignment with a vertical slot 7 coextensive therewith and provided in the inner wall 8 of the door.

The present invention relates to improved means for raising and lowering the panel in the well of the door and for retaining this panel in any of its positions of adjustment.

1927. Serial No. 182,343.

The metallic plates 5 are provided with a pair of spaced arms 9 fashioned to receive a pintle 10 in the slot 11 between said arms. On this pintle a rocking latch 11 is mounted to freely oscillate thereon. This latch is normally held in the position shown in Figure 4 by the action of the spring 12 which exerts a tension thereon serving to throw the latch to the position as shown in Figure I. The latch is provided with a pair of spaced ears 13 having aligned openings 14 receiving the pintle 10. The latch furthermore has a pawl 15 at its lower end, a struclrout lip 16 intermediate its ends, and a stop 17 at the upper portion thereof. In operation, the pawl 15 serves to engage the teeth on the rack bar 6, this pawl being normally main tained in engagement with these teeth by the spring 12.

For controlling the rocking latch 11 and for raising and lowering the panel in the well a control lever 18 is provided. This lever is formed with a pair of spaced side plates 19 apertured to receive the pintle pin 10. A tension spring 20 is disposed between these side plates and is so connected with the pintle that it normally retains the control lever in the position shown in Figure 4. The arms 19 of the control lever serve to engage the struckout lip 16 of the rocking latch when this lever is raised to the full line posit-ion shown in Figure 5 and obviously this engagement shifts the pawl 15 from contact with the rack 6 against the tension of the spring 12. The control lever when in the full line position represented by the character A (Figure 5) offers a convenient means for raising or lowering the panel to the desired position in the well. In view of the length of the lever the panel or pane can be raised or lowered with but the exertion of little effort on the part of the operator.

In the operation of the control herein described, if it is desired to lower the pane in the well the lever 18 is raised to the full line position in Figure 5. In so doing, the side walls 19 thereof engage the lip 16 rocking the latch element 11 on the pintle 10 and moving the pawl 15 out of engagement with the teeth on the rack bar 6. The window may then be raised or lowered to the desired position, after which a release of the lever 18 results in a dropping of the lever 18 until it occupies the position shown in Figure l, resulting in a shifting of the pawl 15 by the action of the spring 12 until said pawl engages the selected tooth of the rack 6. The pawl moves into engagement with the desired tooth and further movement of the pawl is prevented by the stop 17 which engages the side of one of the plates 5 when the pawl is in an operative position. The weight of the window exerted on the pawl and this weight transmitted to one of the plates 5 by one of the stops 17, serves to throw the window or panel against the walls of its guideway to prevent undue rattling thereof.

Having thus described my invention, what I claim is:

1. The combination with a vehicle door having a well therein, a sliding pane, a bracket carried by said pane, a vertically disposed rack in said well, a pintle carried by said bracket, a rocking latch, offset ears on said latch having apertures therein through which said pintle passes, a pawl carried by said latch, resilient means normally maintaining said pawl in operative relation with the rack, a stop projecting from said latch, a control lever pivoted on said pintle intermediate said ears, said control lever having a portion to engage said stop upon a lifting thereof to disengage the ratchet from said rack.

2. The combination with a vehicle door having a well therein adapted to receive a slidable pane, a rack bar in said well, said door having in one of the walls thereof a vertical slot in substantial alignment with the rack bar, means for holding said pane in different vertical positions of adjustment, said means comprising plates secured to the lower portion of the pane and having associated therewith depending arms apertured to receive a pintle, a rocking latch mounted on said pintle and having a pawl portion normally urged in position in engagement with said rack, a control lever also pivotally mounted on the pintle and extending through said slot, said control lever having a portion operative to rotate said latch out of engagement with the rack when in its lifted position, the control serving as a means by which the window is raised or lowered.

3. The combination with a vehicle door having a well therein adapted to receive a sliding pane, a rack bar in said well, said door having a vertical elongated slot therein, means for holding the pane in different vertical positions of adjustment, said means comprising a rocking latch and a pawl carried thereon normally urged in position with said rack, a control lever cooperating with said latch extending through the slot and adapted to release the pawl from engagement with the rack, said rocking latch being provided with CLARENCE E.
