Application November 1 4, 1941, SerialNo. 419,138

'3 clai s. (01. 70-149) This invention relates to combined means for locking the doors and windows of'vehiclesg 'li'he present" invention aims to provide means whereby vehicle windows which are power operated for opening and closing may be automaticallylocked in any desired position of adjustment which they happen to assume, automatically upon and with the operation of lockingIthe vehicle door. The exemplary embodiment of the present invention shown and described in detail herein contemplates the employment "of fluid pressure motive means for moving a vehicle window selectively between opened and closed positions under manual control. P

While'certain constructions have been proposed wherein the motive means is to some'extent fluid locked to retain the window in adjusted position, such means depend upon the presence of an adequate pressure differential for maintaining selected position. After a particular period of disuse no such pressure differential may'be present and accordingly the locking function of the motive means fails; In other instances self-docking piston have'been provided but the present invention renders reliance on such expedients unnecessary. According to the present invention, reliance upon fluid locking is entirely dispensed with insofar as periods'when the vehicle is left with itsdoors locked are concerned.

A door locking'system currently widelyused is the one wherein an element is disposed inside of the door, usually on the garnish molding, for manipulation in conjunction with the outer door handle to render the outer door handle ineffective to open the door without the use of a key. Such adoor locking system is shownand described in detail in the patent to Anderson et al. No. 2,039,- 873, dated May 5, 1936, and the general arrangement there shown is commercially referred to in the art as the Anderson-Bowlus lock. The ensuing specific description and the accompanying drawing disclose adoor lock which follows the general principles of the Anderson- Bowlus lock. albeit in a simplified form. The window locking system of my invention is exemnlified as combined with a door locking system of this type and the novel cooperation of the several e ements in providing a combined door and window locking system will appear to those skilled in the art'from a perusal of the ensuing description 7 in connection with the accompanying drawing.

While a complete and specific embodiment of 1 the principles of the present invention is shown in the drawing and described in detail herein; it i spectively, thereto.

to be'understood that my invention is not limited thereto or otherwise than as defined in the appended claims.

In the drawing: I V

Fig. 1 is a fragmentary elevational view of a vehicle door viewed from the interior, with the upholstery and other portions thereof removed for clearness; r

Fig. 2 is a fragmentary cross sectional View in the same direction as Fig. l but showing the door lock portion on an enlarged scale;

Fig. 3 is a fragmentary view or the window locking latch portion of the device on an enlarged scale; and I Fig. 4 is a view similar to Fig. 3 illustrating a modified form of window locking latch mechanism.

Throughout the severalfigures of the drawing, like characters of reference denote like parts and the numeral IE! designates generally a vehicledoor having'a window ll of the vertically sliding type. As viewed in Fig. 1, the door I0 would be hinged to the vehicle body. along its right-hand edge. 1 7

As stated above, it is contemplated herein that the window I I be raised and lowered by fluid pressure motor means and to this end there is provided a cylinder l4 pivotally" secured to the door H! as at E5 and having a piston (notshown) and a piston rod l6 pivotally connected at its outer end to the outer end of one arm I! of a bell crank it whose other arm l9'carries a pin 28 at its outer end for engagement in a horizontal slot which may be formed by a bracket 2| secured against and cooperating with the under side of a lower framing element 22 of the window II.

The bell crank l8 is pivotally secured against the door NJ as by the pivot pin 24 and movement of the piston in the cylinder M will obviously raise and lower the window through engagement of the pin 20 in the slot formed by the bracket 2|. i

A source of fluiddifierential pressure i indicated in dot-and-dash lines at 28 and manual control valves 29 and 3!! maybe selectively manipulated to divert the fluid difierential'pressure into eitherend of the cylinder l4 through the pair of branch conduits 32 and 33 leading, re-

Reference will now be had to the door locking means per se, following which the relationship between the door locking means and the power operated adjusting means and the locking means for the window will be set forth.

- The-numeral 38 designates a locking bolt which is mounted for sliding movement in a guide 39 associated rigidly with the door Hi. The left end of the bolt 38, as viewed in Fig. 2, enters a suitable bolt opening formed in the door jamb 4D and the bolt 38 may be biased to a locked position by means of a coil compression spring 4| bearing against the right-hand end of the bolt 38 and against a spring seat 42 carried by the panel of the door Ill. The spring 4| may be supported by a guide rod 43 carried by the bolt 38.

A link 45 is pivotally secured to the outer end of an arm 46 which is fixed for coaxial rotation with an outer door handle 41. With the parts in the position shown in Fig. 2, the outer door handle is ineffective and the vehicle door is locked since pivotal opening movement of the handle, which would be clockwise as viewed in Fig. 2, would merely move the right-hand end of the link beneath an overhanging ledge 50 formed on the bolt 38.

The link 45 may, however, be pivoted upwardly to a position where its right-hand end engages against the ledge 58 and permits the bolt 38 to be moved thereby to open position by manipulation of the outer door handle. vertically extending bar is disposed for guided vertical movement. The bar 5| may be guided by the guiding means 39 in cooperation with a strap 53 secured to the door I8. At its upper end the bar 5| is provided with a manual manipulating knob 54 which usually extends through a garnish molding 56 (Fig. 2) of the door window opening whereby it may readily be manipulated.

The bar 5| is adapted to be retained either in the vertical position shown in the drawing or in an upper position whereby it disposes the link in position for engagement with the ledge of the bolt 38 and such joint movement of the bar 5| and the link 45 is accomplished by the provision of a pin 58 carried by the bar 5| and engaging in an elongate slot 59 formed in the link 45. The slot 59 permits free longitudinal movement of the link 45 uponrotation of the arm 48 of the outer door handle 4'1.

For retaining the bar 5| in position for maintaining the link 45 in operative and inoperative position, respectively, a pair of detent openings 68 and 6 l, respectively, may be formed in the bar 5| for engagement with a spring pressed detent pin or ball 62 which may be retained in the bracket 53 in any convenient manner.

From the foregoing it will appear that the bar 5| may be raised and lowered by manipulation of the knob 54 from within the vehicle, but after the outer door handle 41 has been rendered ineffective by closure of the door with the knob 54 depressed and the link 45 in its extreme righthand position (by holding the outer door handle 41 in corresponding position during closure of the door), other means are required for again opening the locked door from the outside. Such means may take the form of a pawl 65 guided for vertical movement in a lock barrel 66 together with a rotatable lock shaft 61 journaled in the barrel 36 and having an eccentric pin 68 for engagement in a horizontal groove 69 in the pawl 65.

Rotation of the shaft 61 can be accomplished only by use of a proper key inserted in the keyhole at the outer side of the lock barrel 6G and such rotation raises the pawl 65 againsta flange 18 formed on a rigid lateral extension H of the bar 5|.

It will be noted that an ordinary slamming of To this end a the door with the knob 54 depressed, but without the intention of locking the door. results in automatically lifting the knob 54 to insure against accidental locking. This results from engagement of a cam face 12 on the bolt 38 which engages against a portion of the link 45 and raises the latter upon movement of the bolt to the right during the door closing operation, the bolt being so moved by camming against the door jamb 40. It is for this reason that premeditated locking requires holding the outer door handle 47 in the position to which it is normally moved to open the door, while the door is being closed to lock the same.

For opening the door ID from the inside of the vehicle, an inner door handle 13 is provided and an arm 14 fixed for rotation therewith engages at its outer end a link 15 which extends to engagement with the bolt 38. The end of the link 15 adjacent the bolt 38 carries a pin 15 which engages in slot 11 formed in the bolt 38. As will be clear from the foregoing, counterclockwise ro tation of the handle 13 as viewed in Fig. 1 will withdraw the bolt 38 from the bolt opening in the door jamb 48, while withdrawal of the bolt 38 from its jamb opening 40 by use of the outer door handle 41, does not disturb the inner door handle 13 by reason of the slot 11.

For locking the Window II in any vertical position which it may chance to assume at the time of locking the vehicle door, a plurality of latch openings 88 are formed about a portion of the periphery of a hub 8| of the bell crank l8. A resilient latch arm 83 is pivotally mounted at one end against the door l8 and its other end is provided with a lug or latch tooth 84, Intermediate its ends the arm 83 is engaged by a lower extension 85 of the bar 5| as by means of a pair of pins 86 carried by such extension and disposed directly above and below the latch arm 83. From the foregoing it will appear that downward movement of the bar 5| to render the outer door han dle inefiective automatically disposes the latch portion 84 of the arm 83 against the hub 8| of the bell crank I8. If the latch 84 is in registry with a notch of the hub 8|, it will enter such 'notch and lock the window effectively against opening or closing movement.

If the latch 84 does not register with an opening directly, the resilient arm 83 will flex and retain the latch 84 against the hub 8| for entrance into a notch 88 upon any subsequent fractional rotation of the bell crank I8. In a modified form of notch illustrated in Fig. 4 a hub 8| is shown as having ratchet teeth whereby the Window is locked only against opening movement thereof. In such case the lug or latch tooth 84 of the latch arm 83 will be correspondingly modified.

What is claimed is:

1. A vehicle door having a window movable to and from a closed position, a latch for the door, means at the outer side of the door and connectible with said latch for actuating the latch to unlatched position, means at the inner side of the door for connecting and disconnecting the latch actuating means, said means including a manually operable member, means for locking the window, and means operable by said manually operable member to render said window locking means operative by and upon latch disconnecting movement of said member.

2. A vehicle door having a window movable to and from a closed position, means for locking said window in various positions, manual means at the interior of the door movable to render the window window in various positions, manual means at the 10 interior of the door movable to render the window locking means efiective a latch for the door and means biasing said latch to latching position, handle means for opening said latch and keycontrolled means accessible externally of the door for rendering said window locking means ineffective automatically upon door unlocking operation by said key-controlled means.
