Patented May 2, 1944 MOUNTING AND REGULATIN G MECHANISM OF SLIDING WINDOWS Laurence Francis Moroney, Moonee Ponds, near Melbourne, Victoria, Australia Application August 2, 1940, Serial No. 349,927 In Australia August 28, 1939 This invention relating to improvements in the 8 Claims.

mountings and actuating mechanism of sliding windows, shutters and the like, is particularly adapted for use with vertically sliding windows of motor-cars and other vehicles. It is not limited, however, to such application since it will be apparent from the description hereinafter contained that the improvements can be applied with advantage to windows, shutters and like elements of stationary buildings of different natures and to movable protective plates in aircraft and 1 other structures.

In the manufacture of doors of motor-cars and other self-propelled vehicles by metal pressing operations as is now largelypractised in the art,

it has been found that there are distortions in r quite an appreciable percentage of the doors and as a result the guideways for the sliding windows are not perfectly vertical. This has frequently occasioned trouble because the required freedom of slidable action of the windows has not been obtained by the use of mountings and regulating mechanisms of previously known constructions. Variations in the guideways, due to distortions, involve considerable work in fitting the window actuating mechanism and in adjustments the guideways be out of truth owing to distortion in manufacture, the window panels in being raised and lowered are liable to wedge or jam in their guideways, Window panels have been so mounted that they are permitted certain flexibility of movement to accommodate themselves to guideways out of truth, but this has oftentimes resulted in breakage of the glass panels when the doors have been slammed to closed position.

A principal object of the invention, therefore, 1

is to provide improvements in the mountings of windows of motor-cars and other vehicles where- ,by the sliding windows have desired rigidity of support and are moved in their set paths with a minimum of noise andwithout risk of jammmg. a

Another object is to provide improved actuating mechanism of simple and relatively inexpen sive construction for opening and closing a slidable window in practically instantaneous manner by rotative movement imparted by the driver or anotheroccupantof the vehicle to a regulator handle which issuitably positioned and can be A further important object is to provide a window actuating mechanism which incorporates means for automatically locking the window panel when it is fully closed and also when moved to any selected open position so that it will neither ascend nor descend under vibratory strains to which it is subjected in the travel of the vehicle, and cannot be raised or lowered except by operation of the regulator handle. Thus, the window of a motor-car or other vehicle can be raised to its closed position for security or to a partly closed position for security while also providing for ventilation. In either case, the window is automatically locked in its set position so that it cannot be forced upwardly or downwardly by an unauthorized person exerting force on it from an external position, but the window can be freely elevated and lowered, as may be desired, by manipulation of the regulator handle from the interior of the vehicle.

A still further object is to provide window actuating mechanism having an improved regulator handle for operative fitment in angularly adjustable position to the rotatable shaft of said mechanism. The handle is characterized by having improved means for effecting an interlocking engagement with the shaft when it is placed thereon in selected angular position and providing for convenient release when it is desired to detach the handle from said shaft.

Other objects of the invention will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention consists of mountings and actuating mechanism for sliding windows having the features of construction, combination and arrangement hereinafter fully described and particularly pointed out in the claims.

Figs. 12 to 22, inclusive, are drawn to enlarged scale.

Referring more especially to Figs. 1 to- 8 of the drawings,v 2 designates the frame of a motor-car door, 3 a pivoted ventilating window, and 4 a vertically movable glass window panel having at its lower end a channelledmetal edging as is customary in the art.

A mounting plate 6 is, secured vertically to the frame 2. Rigidly fastened to said frame and said mounting plate below the window opening and at one sideof the glass panel 4 is a guideway l wherein arunner or slide 8 is fitted. The said guideway preferably consists of a cylindrical hardened steel tube formed with a longitudinal slot 9 which extends from its upper to its lower end and has a width that permits said runner to have freedom of slidable movement in a vertical path while tending to restrain it against undue rocking motion.

fThe runner 8 is provided at its outer marginal portion with spherical steel'balls "ii! which'are revolvable in cage recesses H formed in said runner, adjacent to its upper and lower ends. These balls project slightly beyond the outer vertical edge of the runner and bear against the inner surface of the tube 1. By this means, the runner is adapted for free slidable movement with minimum of friction. In its travel it will be substantially noiseless and will be guided accurately in its vertical path by the tube 7 without being dependent upon guideways formed in the door about the window opening.

Constructed integrally with and extending horizontally from the runner 8 is an arm 12 which is of suitable dimensions to provide a satisfactory 'mounting to rigidly support the vertically slidable window panel 5 by being secured to the channelled metal edging 5 of said panel. An elongated slot I3 is formed horizontally in the outer end portion of said supporting arm and it has an enlargement as indicated by hi at one end thereof for the purpose to be hereinafter explained.

Positioned on the outer side of the mounting plate ii is an operating lever i5 which is fulcrumed on a pin or stud i6 rotatable in a bearing provided in said mounting plate, the fulcrum being at a point to provide in said lever a short arm ll and a long arm I8. A shaft i9 is rotatably fitted to said mounting plate and projects on the opposite sides thereof. Adjustably fitted to the inner end of said shaft is a regulator handle 20, and fastened to the outer end of said shaft is a crank arm 2|.

Revolvably mounted at the end of the crank arm 2| is a small roller 22 which is in operative engagement with, and is adapted to travel along an elongated slot 23 formed in the short arm I? of the fulcrumed lever ii. A helical compression spring 24 may be fitted within the slot of placing the flanged roller into operative position in the slot when the parts are being assembled.

stud while its other end is anchored to a stud 28 on the mounting plate 6. I

The modified construction of vertical guideway 1 for the runner 8 illustrated by Figs. 9 and 10 consists of a hardened steel tube I formed with a longitudinal slot 9 as hereinbefore described, but it is formed with a longitudinal rib positioned diametrically opposite to said slot, and this rib has on its inner surface a longitudinal channel 29. The runner 8 has at itsouter marginal portion an extension 30 which fits within and is guided in its vertical movements by the longitudinal channel 29 so as to more effectively restrain said runner against unduerocking motion. The elongated slot E3 in thewindow supporting arm [2, instead of being horias well as horizontally in said slot l3 during vertical movements of the window-panel 4.

Reference is now made to Figs. 12 to 19 which illustrate in detail the mechanism that is pro-' vided in order that the slidable window panel 4 will be automatically locked at its fully closed position and at any selected open position to which it is moved.

The shaft I9 is constructed in two co-axially aligned parts which hereinafter will be described as the driving shaft 3| and the driven shaft 32. A cylindrical casing 33 is secured by suitable means to the mounting plate 6 concentrically about the driving shaft 3|, and it is formed with a centra1 apertured boss 34 to provide a suitable bearing for said driving shaft.

The casing 33 has one portion 35 of its inner surface smooth in order to ensure a satisfactory bearing surface for a rotatable element. The other portion of the casings inner surfac in dicated by 35 is of slightly reduced diameter and. is formed circumferentially with serrations 31 which are closely spaced and adapted for engagement by locking devices to be hereinafter described.

Fixed on the inner end of the driven shaft 32 is a block or rotor 38 having a cylindrical member 39 of such diameter as to fit rotatably, but snugly, within the smooth portion 35 of the casing 33. To further ensure freedom of rotatable movement of said block, its surface 43 which is contiguous to the mounting plate is plane.

Formed on that surface of the rotatable block 38 which is opposite to its plane surface 40 are two studs 4| whereon pawls or detents 42 and 43 are pivotally fitted. Stops 44 and 45 for said pawls corresponding in thickness thereto are formed at diametrically opposite positions on said block. A bearing recess 45 is formed centrally in the block 38 to provide a seating for the inner end of th driving shaft 3|, which is of reduced diameter.

Each of the pawls 42 and 43 has at one end a pointed tooth 41 and opposite to the tooth a flat surface 43. A helical compression spring 49, accommodated in a hole 50 in the stop 44, bears at its opposite ends on the flat surfaces 48 of the pawls and by the outward pressure exerted by said spring the teeth 41 are normally maintained in engagement with the serrations 3'1 to lock the block 38 against rotatable movement.

Each of the pawls 42 and 43 has on its inner edge a recess 5| of substantially semi-circular shape and a flat portion 52. A cam 53 of special construction is fastened on the driving shaft 3|, being position between said pawls in operative relationship theretosee Figs. 18 and 19.

The cam 53 has two diametrically opposite projections 54 and 55 which are conformable to the recesses 5| of said pawls, and two projections 55 and 5'! which are at right angles to the projections 54 and 55. The projection 56 is designed to operate each of said pawls, while the oppositely set projection 51 does not act upon either pawl, but it tends to prevent tilting movement of the driving shaft 3|. The pawls 42 and 43, the stop 45, and the cam 53 are so designed that sharp percussive action is avoided, and the driving shaft 3| having its inner end seated in the recess 45 in the rotatable block 38 is held firmly and is restrained against vibratory motion. The block 38, studs 4| and stops 44-45 may advantageously be formed inte grally by diecastin When the window panel 4 has been elevated to its closed position, the parts of the mountings and actuating mechanism are in the relative positions seen in Figs. 1, 3 and 18. The window panel is securely locked against opening movement by the engagement of the pawl teeth 4"! with the casing serrations 31, thus preventing rotatable movement of the block 38. The panel is further locked against movement by the crank arm 2| being disposed at approximately right angles to the slot 23 in the fulcrumed lever.

When-it is required to open the window by lowering the panel 4, the requlator handle 20 is rotatively'moved in clockwise direction. Upon the initial rotational movement of the driving shaft 3| whereon said handle is fitted, the cam projections 55. and 56 act simultaneously, the former upon the recessed portion 5| of the pawl 43 and the latter upon the flat portion 52 of the other pawl 42, to impart pivotal movement to both pawls on the studs 4| against the pressure of the spring 49. The teeth 41 are thus withdrawn from engagement with the serrations 31. The pivotal movement of said pawls is limited by their flat surfaces 48 contacting with opposite sides of the stop 44.

The rotational movement imparted to the driving shaft being continued by pressure exerted on the regulator handle 20, the cam projection 56 acting through the pawl 42 upon the relative stud 4| and the stop 44 imparts rotary movement in clockwise direction to the block 38 and to the driven shaft 32. Rotary movement of the driven shaft imparts turning motion to the crank arm 2| whereby roller 22 is caused to fulcrum the lever l5 on the pin or stud l6, said roller travelling along the slot 23 in the short arm of said lever. As the lever turns about its fulcrum, the lowering of the flanged roller 25 at the end of its long arm l8 permits the hori- Zontal arm l2 of the runner 8 with the window panel 4 that is mounted thereon to descend under gravitational force, the degree of downward movement of the window panel being regulated by the degree of rotation of said lever. The clockwise downward movement of the lever is against the resistance of the spiral spring 21, and in this movement of the lever the roller 26 travels along the slot E3 in the horizontal arm l2. As the lever l5 approaches its horizontal position, the leverage of the window panel about the ful crum l5 increases. But the leverage exerted by the crank arm 2i acting through the operative connection of its roller 22 also increases.

During the latter part of the downward movement of the window panel, the leverage about the fulcrum l6 and the leverage exerted by said crank arm progressively decrease so that substantially uniform pressure on the regulator handle 20 induces substantially uniform motion of the window panel.

The window panel having been lowered to the extent that is required, pressure is removed from the regulator handle 2|], whereupon thecompressed spring 49 forced outwardly the ends of the pivoted pawls 42 and 43 so that their teeth 4'! are instantly forced into engagement with the serrations 31 of the casing 33 and the block 38 and driven shaft 32 are locked against rotation.

When the regulator handl 2B is initially moved anti-clockwise to raise the window panel, the cam projections 54 and 56 act simultaneously upon the recessed portion 5| of the pawl 42 and the fiat portion 52 of the opposite pawl-43150 pivotally move said pawls and thus withdraw their teeth i! from engagement with the, casing serrations 3'2" against the pressure of the spring 49. Upon continuation of the handle movement, the. cam part 55 acting through the pawl 43 upon the relative stud 4| and the stop 4, imparts rotary movement to the block 38 and the driven shaft 32 fixed thereto. Consequently, turning motion is given to the crank arm 2| and its roller 22 applies power to fulcrum said lever on the pin or stud I6 while travelling along the slot 23 in said lever. The flanged roller 26 at the end of the long arm of said fulcrumed lever thereby exerts force to elevate the horizontal arm 12 with the window panel 4 mounted thereon. In this upward movement of the parts, assistance is given by the spring 27, and the roller 26 travels along the slot l3 in said horizontal arm 12. The correct vertical line of movement of the horizontal arm and the supported window panel, when being lowered and raised, is ensured by the slidable operation of the runner 8 within the rigidly fitted vertical guideway '1.

Immediately pressure is removed from the regulator handle, the teeth H of the pivoted pawls are automatically returned from their released positions into effective engagement with the casing serrations in the manner and for the purpose hereinbefore explained. In consequence, the window panel is locked with security in the selected elevated or lowered position. It cannot ascend nor descend under vibration to which it is subjected, and it cannot be moved upwardly or downwardly by forces applied to it until such time as the pawl teeth 41 have been withdrawn from the casing serrations 31 by operation of the regulator handle 20.

The object of the helical compression spring 24 fitted in the slot 23 in the short arm ll of the lever l and bearing against the roller 22, as is illustrated in Fig. 11, is to compensate for the increasing torsion ofthe spiral spring 21 during the latter part of the downward movement of the window panel 4 and for the decreasing torsion of said spring 21 at the end of the upward movement of the window panel. Consequently, the

force which is required to be exerted on the regulator handle 20 to raise or lower the window panel will be substantially the same, irrespective of the positions occupied by said panel. The same result may be achieved by the modification illustrated in Fig. 10, according to which the slot [3 in the window supporting arm i2 is inclined, instead of being horizontal, and the roller 26 at the upper end of the lever 15 is thus constrained to travel in an oblique path in the vertical movements of the window pane].

When the regulator handle 20 is operated in clockwise direction to lower the window panel 4, the roller 26 initially travels upwardly in. the slot l3. In the first half part of rotational movement of said handle, the window panel descends lower than the half-way point, the extent of its downward movement beyond the half-way point corresponding to the vertical distance between said roller when in its initial and end positions in the slot. During the latter half part of the movement of said handle, the window panel descends to its fully open position, the roller 26 then travelling downwardly in said slot 3. Similarly, when the handl 20 is operated in, anticlockwise direction, the window is moved upwardly a distance less than to the half-way point in the first half of thev rotational movement of said handle and a greater distance in the latter half movement of said movement. By means of this construction, the effect of the increased torsion of the spring 21 during the latter Part of the downward, travel of the Window panel is balanced.

It will be understood that varying degrees of vertical movement imparted to the window panel by any desired rotatable movement of the regulator handle 26! can be obtained by adjusting the several ratios of the different levers of the mechanism. In the exemplary embodiment of the invention illustrated by the drawings, the ratios are such that the regulator handle is turned approximately to effect full raising and full lowering movements of a window panel of 14 inches height. Consequently, the window panel can be opened and closed in practically instantaneous manner by simple movements imparted to the regulator handle.

The actuating mechanism now provided for raising and lowering the wndows of motor-cars customarily includes a regulator handle which is angularly adjustable on a rotatable shaft or spindle of the mechanism so that it can be manipulated with ease by the driver or other occupant of the vehicle.

It, is desirable that the regulator handle, in addition to being angularly adjustable, should be speedily detachable from the shaft or spindle and will be automatically locked in operative association with the shaft or spindle when fitted thereon in the selected angular position.

The driving shaft 3| of the Window actuating and locking mechanism hereinbefore described extends slightly inwardly of the frame 2 and its inner end is fashioned as a boss 58 of polygonal configuration which is formed with a circumferential groove 59-see Figs. 20 to 22. The handle arm 20 preferably has at its outer end a finger knob as EU for convenient operation, and at its inner end it has a base plate 6| of discoid shape adapted to be secured flatwise to the interior surface of the door or body of the vehicle. Formed integrally with the base plate of the handle arm is a socket 62 having its inner surface of polygonal contour correlated to the configuration of the boss 58 onto which it is adapted to be slidably fitted so as to be incapable of independent rotary movement thereon.

A finger catch 63 is pivotally fitted on a stud 64 in a shallow recess 65. formed in the outer surface of the base plate 6|. This catch is pivotally movable in a slot 66 formed in the socket 62 and its inner end is adapted for locking engagement with the circumferential groove 59 on said boss 56. Anchored at one end to the base plate 6! is a light compression spring 6! which bears at its opposite end against the outer portion of said pivoted catch.

When the handle, socket BI is slidably fitted over the polygonal boss 58 in selected angular position, the spring-press catch automatically engages the groove 59 and locks the two parts in operative association so that rotative movement given to the handle arm 20 transmits similar movement to the shaft 3|. The handle arm capable of many angular adjustments, the degrees of which are determined by thesides of the polygonal boss. To disengage the handle, it is only necessary to press with the finger against the outer end of the pivoted spring-pressed catch I 63 to release its inner endfrom the groove 5Q whereupon the handle can be slidably withdrawn from the boss 58.

The improvements in mountings and actuating mechanism are subject to modification in-constructional details and in matters of design, particularly in the application of the invention to sliding windows of different designs and those of vehicles other than motor-cars. The invention contemplates other modifications which will be apparent to those skilled'in the art. The described arrangement of the slot and roller con nections between the window-supporting arm l2 and the long arm l8 of the operating lever I5, and between the short arm I! of said lever and the crank arm 2| is that which is preferred, but the arrangement of said parts may bereversed, that is to say, the rollers 28 and 22 may be fitted to the window-supporting arm l2 and to the lever arm l1, respectively, with the co-operating slots l3 and 23 formed in the lever arm l8 and in the crank arm 2|, respectively. Moreover, the vertical guideway for the runner 8 may comprise two tubes I in parallel spaced relationship instead of the single tube 1. All such modifications are deemed to be within the ambit of the invention as defined by the appended claims,
