To allwh'om t may concern.: l

Be it known that I, ERNEST E. HEIN Tz, a citizen of the United States, residin at Detroit, in the county of Wayne and tate d of Michigan, have invented certain new and useful Improvements in Window-Regulators, of which the following isa specification.

This invention relates to window regulators, and has for its object. a window regulator which is actuated by a lever sliding along the garnish-rail .of the window. It is primarily intended for application to closed automobile bodies.

The rear quarter window presents somewhat of a problem in applying the usual window regulator thereto. In fact, it has been such ayproblem that the' majority of cars have not used a window regulator on the rear quarter window but have employed the old pull strap. Most window regulators are designed to have the crank handle directly in the middle of-.the window. This is a very unhandy and inconvenient arrangement with the rear quarter window as it brings the crank handle vdir ectly at the side of the seat. have the raising lever forward of the center of the window would in a great many closed jobs interfere with some of the fixtures,l such as the usual toilet case that is placed in a high grade car. It is the object of the present invention to provide a window regulator which obviates :these objections 'byx hailfing a handle that runs along the garnish rai v Furthermore, the window regulator 1s provided with such an arrangement of levers as to make the operation of raising and lowering the window extremely easy. The lever arrangement is such that the thrust and pull on the window is a substantially vertical line thrust at the center of the window rail and consequently the window will not bind or cramp in the window-ways to cause friction and diiiculty in raising or lowering. i

Another feature of this regulator is a special form of clutch which offers no resistance to any effort applied to the lever handle but.- which locks when effort is applied through the window as will more fully appear in the description following.

In the drawings,

Fig. 9 is a rear View of the supporting plate or cup showing the adjusting devices for the counterbalacing spring.

The regulator supporting plate is designated a and is screwed to the inside of the lock-board b. In back of this plate and in the fro-nt of the lock-board is a cup c in which is locatedthe concaved washer d provided 'with the bolt and nuts e and fitted in to the supporting plate a. This washer forms ahub about which winds the spiral counterbalancing spring f.\ `This washer is secured to the inner end of the spring by the hook g on the spring. This washer d is pro-` vided with teeth tA(F ig. 9) with whichyis .adapted to engage the catch z which is cut off at one side. When the catch is in the position shown in Fig. 9, it locks in the gullets of teeth h and prevents the .hub from turning. When it is desired to tighten or loosen the counterbalancing spring this catch z', which is on the back of the cup o and exposed through the board b, may be readily reached by simply removing the trimming on the front of the board b. The

4catch may be then turned to bring the flat side adjacent the teeth 71,. This permits the hub to be turned by placing a tool therein. The hub may be turned such a number of notches as is necessary to tighten or loosen the spring. Thereupon the catch z' may be turned back into engagement between the teeth to hold the hub fixed. The other end of the spring is engaged by the stud y' which 'is fastened togthe lever lo. This lever k is fulcrumed onthe hub boltv e. The lever k has its swinging end pivoted to the lever m which has one end secured to a check link n, which is hungfrom the pivot p secured to the anchoring strip w. The lever m has I its end of largerswinging arc pivoted to a short link Q which in turn is pivoted by the pin'and cotter r to the bottom rail s ofthe window.4 The supporting plate a is countersunk at t, permitting the pin j to swing in the plate and wind up the counterbalacing spring when the window goes down.

Pivoted on the bolt e is a bell crank lever fw whose vright hand arm 1 cooperates with a link gto form in effect' a pair of toggle arms for thrusting on the windowv lifting lever fm..

When these toggle arms reach substantially a center line position, as shown in Fig. 2, the pin and shoulder a prevent the toggle arms from throwing any further. This center position prevents any effort directed on the window lifting lever m from breaking the.

toggle. The consequence is that when the window is in'itsupright position these toggle arms present an effective lock to hold itl in this positionwithout any other aid, such as the clutch presently to be described.

The position of the levers is such in the Ylowermost position of the window as to ef-l fectively-lock the window from jumping due to the jolting of the car. Note the position of the operating parts in Fig. 6. Any elfort of the window to raise is resisted by the levers ultimately transmitting a straight line thrust on the link 2. Thisv permits a cushion 100 of felt or rubber to be used at the bottom of the window travel and the window may be jammed thereinto and locked in antirattling position by the` levers being arranged so that'one .of them (2) assumes a dead center position t0 any thrust originating in the window.

breaking of the toggle is effected vsimilarly by anotherpair of toggle arms y and' 1 thrusting on the same iXed pivot e. As is well known, toggle levers or arms convert a force striking the toggleat the knee and traveling through a considerable distance into a greater force at the ends of the toggle traveling through a less distance. In short, the leverage is considerably multiplied. This takes 'place in both sets of 'toggle arms.

Hence the leverage is considerable. Furthermore, `the toggle arms 1 and y secure the additlonal advantage of locking against any l1/screwed to the inside of the endwise thrust brought thereupon. And additionally, the toggle lever le, in conjunction with the stud j, acts as a counterbalancing spring winding element. j y

- The toggle arms, 1, y, are broken or straightened out by the movement of the bell crank lever w. As the resistance arm of this lever is considerably shorter than the power arm it will be vevident, thatv herey also the leverage increases. connected by the engages in the groove of the channeled track lock-board. This track comprises a channeled track having turned-over ianges 5, 6l (see A .carriage 7 rides on this track which 1s provided Awith fiber rolls 8 that are riveted theretor and that run in the channel. Slitted The end of this` lever' is link 2 with a. slide 3 which fiber blocks 9 engage the under flange 6 of thetrack and straddle the same. The hooks v1() of the carriage engage over-these blocks.

A slitted liber block 11 engages inthe straddling position overtheipper flange 5.

nstruck-in hook-12 engages over this block.

These hooks 10 and 11 in combination with the blocks securely lock the carriage on the track so that it can be disengaged therefrom j only by sliding off the end. The slide 3 is locked loosely into the carriage when the carriage is assembled upon the track, as will beseen from the position of the parts in Fig. 2. This slide 3 of springs 13 anchored in the ends which engage over the prow'at each end of the slide and tend to force the disks or rolls 14 toward each other. Notice, however, that the upper' surface of the slide 3 that supports the rolls "inclines upwardly toward the center from each end, forming wedging surfaces. Hence any attempt to move the slide as an effort applied through theA link 2 will force a wedging surface up under either roll and consequently wedge the roll between the block and the track and prevent any movement. On the other hand, if the carriage is moved by the handle 15, the turned-in lug 16 (Fig. 7 will move the roll 14 and through it thrust upon the prow of the slideand in noway cause the same to bind against the track. The consequence is that a clutch is afforded which locks when actuated through effort applied to the window and which runs free when effort is applied through the handle.

It will be apparent thatthe lifting and lowering can be done bythe levers alone, omitting the check link fn, and the lower end of the lever m. In this event it will be advisable to omit the link g and attach the lever m directly to the window rail s. However, the check link n and the extended lever is provided with apair m play a very important part in anim-v ment. Of'cou'rse, the very best length "of end of the lever m to travel in a substantially vertical path. The pivot 20 describes afixed arc. Without the check link n the link Qv on the first thrust movement of the lever m would swing through 90 until it jammed against the bottom of the window rails; in the first pull of the lever m, in lowering the window, the link g would simply swing into straight line positionl with the lever m. Either of these occurrences would tend to cramp the window in its ways. The check linkby reason of swinging in a determined arc compels the end of the lever m to travel in a prescribed path and because of the loose connection through the link g with the window takes the ,stresses off the window frame and transfers them to the check link where they may be taken care of with a minimum of friction and loss of power. It will be found by experimentation that almost any length of check link will cause the end of the lever toV travel through almost a straight vertical line within a given range of movecheck link and placement will dependv altogether upon variable factors, such as the length of the levers m and` c, and hence, it will have to be in each case determined by a cut and try method.

The handle 15 is offset over the fixture in no way interferes with any of the fittings in the car.
