-*This invention relates to improvements' in the artof window regulators.

I It is` onepof the primary objects of. the invention to prov-ide a.I positive operating mechanism for a movable Window and a= cooperating positive loch to hold the parts in their adjusted'positions. y v

It is a further object to provide an intermittent lock of this character operable-by the controll handle for the window. n

Still another Objectis to provide a relativelyV simple Aconstruction necessitating the useoflittle' additional mechanism without ina-kingany sacricein the function of the parts.

@ther and more specific objects will appear from the following description con# sidered in connection with the drawings in Which:

Fig. 1 represents a broken elevational view of an automobile frame part embodying our invention.

Fig. 2 is a horizontal sectionalI view through the same.

Fig; 3' is an' enlarged detail' view of the regulating and locking mechanism.

Fig Gis1 a horizontal sectionall view of the structure shown in Figi 4'.

Referring' to the details of the drawings there' are shown cert-ain portions of an automobile door` Sthe upper part of which includes awindow opening adapted to be closed by amovable window 10 when the latter is inf raised position. The" window may` be lowered into the window Well 12 by the construction hereinafter described, beR ing guided in such movement by means of the usualfwindow guides 14 mounted' in the frame part- 8. The door and trame member 8 andwindow may be of any approved construction the details thereof forming no part'` of our present invention.

For the purpose'ofsuitably adjusting and looking the window inany of its operative positions. we provide the following mechanism. A supporting' plate 16I is mounted upon one of the side members of the-frame part 8- and is'V designed to carry the entire window controlling mechanism; Thisnnechanism includes'the operating handle 18-"operatively connected to jthe window regulating arm 2O pivoted at 21 to the support-v 16the outer or free end thereof carry-,inge the roller 22 or other means designed to" engage a member carriedby thelower por# tionlofthe window 10' Ais1' shoW'nf tliiasfconnection includes the guide member 21car ried by the1transversermember. 26 which'e braces the'A lowerportionof the window.- As the arm 2O 'swingsabout itspivot' the roller' 22 causes a vertical movement of'l the Wine dow 10 as Willbe understood by those-skilledy in the art.

rlheY connection between the operating hand lever 18 and the arm 2O includes the' operating shaft 28`carried byfJ the plate 16 and serving as a: pivot for thehand lever 18. ber 30 provided upon itsf surface with a series of spaced teeth 432 mounted' for' en gagement with they teeth 34v upon thef op erated` gear member 36.-.In the'fconst-ruction'shown the gear member 36 is'fmounted uponV the same pivot'as the arm 205:.,the latter being secured tol the` gearl asindi.L cated' at 38 for rotation'` therewith. rEhe teeth' 32 uponv the ope-rating element'ft are spaced apart further than the cooperatin'g teeth` 34 on' the..4 operatedY memberr 36 sol as to provide certain lost motion betweenl the operating shaft 281' and operated member 36.' Thiswill be more fully.k understood by reference to Figs. 3 and2 4 showing the toothed operated member 30' moved to its dilferent operative positions-v. It is to be noted that the gear member isj never free ofthe gear member SO'SO as to-'be rotatable more than the distance ofra spac'e between the' teeth 34 on the member 36.'- Ther'e is accordingly provided an operative* connectionfbetwe'enf the handle 18f and the anni 20' by which the arm can be swungabout The shaft 28 carries-an operating,inern'-` its pivot to any extent permitted by the free endY thereof. l

For the purpose of providing a'L positive lock for the arm 2O a lockingl element 4;() is pi'voted as aty @to the plate 16: This? locking 'element includes the lo'clin" lug" 44 formed upon an intermediate portion there'- of and an actuating portion 46 preferably at the outer or tree end thereof; The luge/2 i mounted to' be moved into position'beto raise the lug tween the teeth 34 of the operated member 36 or to be moved upwardly out of the path of movement of said teeth to lock or unlock the operated member against. or for pivotal movement. The position of the lug 44 is controlled by theV teeth 32 of the operating member in that the operating cam 46 is designed to be engaged by said teeth 32. The element is held in engagement with the member 30 by means of the spring member 48 preferably wound upon the pivotal shaft of said element and engaging over said element as indicated at 50.

The weight' of the window is counterbalanced by means of the spring 52 connected to the supporting plate as at 54 and to a remote point on the arm as at 56. This spring relieves the gears 30 and 36 and handle 18 of the weight of the window.

'Theoperation of the device is as follows. When it is desired to move the window tol a different position` the'operating handle V18 is rotated to a position such that one of the teeth 31 comes under the operating cam 46 44 from its position between the teeth 34 on the operated member 3,6'. Just prior to or as the locking element isfraised one of the teeth 32 engages a tooth of the operated member to move the same to a new position. The relation of the parts at the time the operatedmember 36 is unlocked and being moved is shown in Fig. 4 whereinthe operating member 30 is being moved clockwise as viewed in vsaid figure. Furtherrotation ofthe handle 18 and gear member 30 rotates theoperated member 36 counterclockwise. and releases the latching element 40 from the tooth 32, sothat the locking lug 44 drops between the next pairof teeth 34 on the element 36. The gear 30 can then be rotated a limited distance as will be seen from Fig. 3, without unlocking the gear member 36 for rotation butany rotation of the gear 30 sufficiently to cause engagement of the teeth-32 and 34, as seen in Fig. 4, causes one of the teeth to pass beneath the cam 46 to raise the locking element 40 to unlock the same permitting the operated member 30 to be moved. l

It will be seen that by this construction the arm 20 is normally held positively locked in its adjusted position and that it is only freed from such locked condition by a move- Vmentrof the operatinghandle 18 to release the locking element 40. `This operated element 36 is accordingly intermittently locked Vand unlockedv dependent upon the position `of the operating handle 18, its shaft 28 and the gear 30.

lhile we have shown and described certain specific constructionsit is to be understood thatthese are merely illustrative of the invention. the scope of which is defined in the appended claims.
