To all whonm't may concem:

Be it known that I, Donn MILLER, a'citizen of the United States, and a resident of Toledo, in the county of Lucas andState of Ohio, have invented certain new and useful Improvements in \Vindow-Regulating Devices of which the following is'a specification.

Thisinvention relates to window regulators and consists of an improved window operating mechanism particularly adapted for use in automobile body construction of the limousine or closed body types. The device of the present invention is designed with the particular object of producing a regulating .lllGClltllllSIIl possessing important advantages over the mechanisms at presentused and which will be sturdy and economical of construction and more efficient in its operation.

Important and valuable features of my improved regulator include an improved construction and arrangement of the parts which allows of the ready application of the device to the door or body construction where its use is desired with the minimum of interference with other structure and thereby avoiding to a large degree weakening other membersof -the body construction,

as for examplethe lock board of a doorstructure when mounted thereon. The im-' 'proved mechanism is of a design which allows ot-its operation manually from a plurality of conveniently located points thereby permitting a desirable choice of location of the operating handle which may thus be determined with relation to the-location of the seating arrangement of varied bodied designs. It is of few and simple parts which may be reassembled upon a suitable. supporting plate and therebyadapted for unit installation and the parts thereof are of a size and arrangement which permits of-generally universal application to the commercial narrow and wide door standards of the industry and likewise for operating the glass of the body rear quarter as the mechanism is compact and adaptable to short or long lifts as the circumstances require. In addition my improved mechanlsm by reason of its improved manner ofoperation allows of liberal tolerances and in 0011- sequence economy in its manufacture as dellcate parts and accurate adjustments are not essential to its proper operation. It is moreover designed to support and apply the hit dency of'the glass ing forces to the underside and centrally of i the window glass, thereby to avoid the tenbinding within its Guiding channels or slots. My improved mec ianisrn further provides for the desirable counterbalancing of the window pane in a manner to insure ease in its action.

Further features and advantages of my improved regulator mechanism will be more fully understood by reference to the accompanying drawings illustrating a desirable embodiment thereof and wherein like reference numerals are employed to designate the corresponding parts in the several views.

In theldrawings:

Fig. 1 is a View in side elevation illustrating tie regulator mechanism of my invention as applied to an automobile door structure for operating the'glass thereof.

Fig. 2 is a vertical cross-sectional View thereof.

Fig. 3. is a view corresponding to Fig. 1 with the parts shown in the opposite extreme position as assumed when the glass'is fully lowered. Y

Fig. 4 is a view in side elevation illustrating a modification in the location of the operating lever.

In the approved embodiment of the features of my invention as herein disclosed the mechanism is illustrated as applied to an automobile door structure for operating the window or glass thereof. The door is shown composed of the frame members 1, the vertical members thereof being provided with the usual vertical and inwardly directed guide slots 2 providing guide-way within which is received the window glass 3 adapted to be moved vertically for opening and closing the window aperture in the usual manner. The glass is supported at its lower edge within a channel member 4 and the door is provided with the usual cross-bracing member or look board 5 connecting the opposite vertical frame members.

The operating parts of my improved window regulating device are desirably mount ed upon a supporting plate 6, which, as shown, is a flat plate of suitable form and is attached to the lock board 5 of the door by means of the securing screws 77. The operating parts comprise a window regulating lever and toggle actuating links or levers therefor designed to be movable above of operation and smoothness substantial or extended movement to the operating end of the operating lever, which will be vertical and rectilinear in direction.

Of the operating parts, 10 is the operat- .ing lever having an arm extension provided with a pin 11 fitted within the elongated slot 12 of connecting'member 13 depending from and attached to the supporting channel 4 carrying the glass to be operated. The lever 10 is fulcrumed upon a pin 15 supported upon the outer extremity of a lifting bell-crank lever 16 having a rearwardly extended arm 17 rigidly connected .thereto and keyed upon a bearing pin or spindle 18 suitably journalled and supported by the plate 6. The operating lever 10 at one end is pivotally connected at 20 to a toggle arm 21 which at its center portion is provided with a fulcrum pin or roller. 22 fitted within the horizontally extended and enlongated slot 23 formed in the supporting plate 6, as shown. The opposite end of the toggle arm 21 is pivotally connected by a pin 25 with an arm 26 of a bellcrank lever having a second arm 27 and pivotally supported upon the center bearing spindle or pin 18, as shown. Upper and lower equalizing

arms

29 and 30 are arranged, as shown, each pivot-ally supported at its outer end upon a fulcrum pin or roller 31 fitted within a longitudinally extended slot 32 formed in the supporting plate 6.

' The inner ends of equalizing

arms

29 and 30 are pivotally connected respectively to the

arms

17 and 27 of the bell-crank levers by means of the pivotal bearing

pins

34 and 35.

As will be noted the horizontally extended guiding

slots

23 and 32 are formed in the plate 6 in the horizontal plane of the axis of the bearing pin or spindle 18 which for distinction is hereinafter referred to as the center hearing. The

arms

17 and 27 of the respective bell-crank levers are arranged in right angular relation to their

complemental arms

16 and 26 and are reversely disposed in symmetrical angular relation to the horizontal plane of the center bearing. The pivotal connections 34 and are likewise symmetrically positioned at opposite sides of the horizontal line through the center bearing, with the equalizing arms reversely and symmetrically positioned above and below this horizontal plane. The bell-

crank lever arms

16 and 26, the operating lever 10 and the toggle arm 21 form an articulated rectangular toggle structure the opposite members of. which are parallel and of equal length. Also, as will be noted by reference to Fig. 1, the upwardly extended portion of the operating lever 10 from the center of pivot 15 to the center of the pivot 11 corresponds in length to the distance between the center of pivot 15 to the center bearing or axis of the center bearing spindle 18.

As shown in Figs. 1, 2 and 3 the manipulating means for the operating levers consists of a crank-handle or lever 40 fixed upon the external end of a shaft 41 suitably journalled upon the supporting plate 6 and .having secured upon its inner end portion a pinion 42, the teeth of whlch mesh with a gear segment 44 supported upon an exten-- sion of the bell-crank arm 17 and at its lower end upon an arm 45 which is an extension of the lever 16. Thus the gear segment is rigidly supported by the lifting lever 16 by means of its rigid arm extensions -whereby the gear segment 44 rotates about the center bearing 18 and is accordingly formed concentric therewith. Turning of the crank 40 will efl'ect the movement of the operating levers to transmit the movement to the glass 3 for raising and lowering of the latter.

In the operation from the extreme elevated position, as indicated in Fig; 1, the respective levers will move in the directions as indicated b the arrows and simultaneously the

sliding fulcrums

22 and 31 will move horizontally within the slotted guideways until the parts assume the final positlon, as indicated in Fig. 3, wherein the glass is shown fully lowered. In this movement the operating end of the operating lever 10, as defined by the connecting or coupling pin 11 will move vertically with a rectilinear movement by reason of the toggle action of the rectangular articulated structure composed of

members

10, 16, 21 and 26 during which movement the

pivotal points

15, 20 and 25 will pass center with relation to the horizontal plane through the center-bearing 18. During the operating movement the' symmetrical angular relations of the links are maintained under the controlling influence of the sliding fulcrums, which as indicated, are guided to move in a rectilinear plane. As otherwise expressed with relation to thearticulated rectangular structure, composed of

members

10, 16, 21 and 26 the center bearing 18 and sliding fulcrum 22 control the movement of the respective links whereby they will maintain a symmetrical relation at all times to the horizontal plane whereby the movement imparted to the coupling. pin 11 will be rectilinear and vertical in direction.

The characteristics of the operating move-- ment may perhaps be best i'niderstooiil when considered with respect to the vertical plane as defined by the line of travel of the pin 11. It will be. notedwith relation to this vertical plane that the lifting lever 16 and the operating lever extension. of a length equal thereto, conform to the two sides of a triangle which uniformly change their angular relation during their movement to reversal of position. In consequence, the

movement will define the base of the respective triangles completed by the two side members both above and below the central longitudinal plane and accordingly its pathv of movement is established as a straight line.

This symmetrical movement of the angular members is insured by the controlling action of the

fulcrum points

18 and 22 which are fixed with reference to the horizontal plane. It, therefore, occurs that the angular members are movable only in unison and in what may be termed amovablesymn'ictrical relation to a fixed plane to produce a straight line or vertical operating movement. It will be noted that in the full past center movement in one direction as from the extreme upper'to the extreme lowerposition of the glass 3 the fulcrum 22' will move from initial position indicated in Fig. 1 to' the oppositeend of the slot 23 and return to initial position as indicated in Fig. 3.

With the described construction 1 desir-' ably associate suitable means -for counterbalancing the weight ot the glass and other moving parts and for this purpose is here shown a helical spring 50. This spring at its innermost coil is bent to a squared form and closely fittedtoa uared portion 51 of the center bearing spin le 18and the outer extremity of "the spring is formed with a -loop or hook portion 52 fitted to an extension of the pivot 25. With this arrangement the spring is assembled under tension, as indicated in Fig. 1, to exert a pressure in the direction tending to elevate the glass and to a degree to produce a counter-balancing eflect. Incidental to this structure the tension of the spring may be readily varied to meet S)8ClfiC conditions by assembling the square innermost coil thereof in varied positions upon the squared portion 51 of the center bearin While as dls closed in Figs. 1, 2 and 3 a segmental rack and lever operated pinion may be employed to manipulate my improved regulating device, and as will appear quite obvious from thecon'struction other manipulating means may be employed there with for the lever arrangement is susceptible to manipulation from differently located points. This offers a material advantage in permitting the location of the operating lever to be varied in accordance with the body seating arrangement. As illustrative thereof a hand lever or handle may be extcrnally fixed to an extended portion of the fulcrum pin 31 to operate with a sliding movement to manipulate my improved clevice. As will be obvious this latter arrangement may be employed alone as the manipulating means or'in conjunction with other means. as shown.

As further illustrated in Fig. 4 and in .dottedllines} in Fig.2, my improved device may also bemanipulated by a hand lever 61', ,fixed toan externallyv extended portion of the "center bearing spindle 18. Also where thismeans is employed as the sole means of operation, as indicated in Fig. 4:, and as will be understood,.the segmental rack and pinion of Figsll to 3 may be omitted to- 'gether' with the supporting arms therefor.

My improved mechanism'as disclosed is of a type particularly well adapted for economy in manufacture and particularly adaptable to varied installations by reason of its compactness and as hereinbefore referred to is advantageous and economical sen'ibling of the operating parts at the point of manufacture thereby allowing install-ation as a unit by the body builders. The rectangular articulated lever structure is efficient in its operation and adapted to impart or transmit a long throw movement to the window with economy of structure by reason of the toggle action and pass center movement. This *movement is moreover definitely controlled and guided by the movable fulcrum points whereby the operating end of the operating lever moves in a straight line which insures smoothness in its operation'by avoiding lateral pressures; My improved structure as aforesaid is further advantageous in allowing for the varied positioningof the manipulating levers and the presence of the counter-balancing spring provides for the takinq up of all lost motion in a manner, w llCll contributes to silence in operation.
