Renewed November 28, 1938 Claims.

This invention relates to window regulators for vehicles such, for exa mp1e,as used in raising and lowering the windows of automobiles and is concerned with a regulator of the type shown and described in the appl olson, Serial No. 132,7 regulator.

ication of Stanley W. Nich- 38, entitled Vehicle window in its travel.

Another object is to simplify the regulator mechanism of the above type, particularly with reference to the mounting of the crank arm in such a manner that a sturdier and less expensive structure is provided.

A further object i noise incident to a s to eliminate the clicking regulator of this structure at the time when the crank arm and link are brought into contact raising and lowering with each other during the movements.

For purposes of illustration, an embodiment of the invention is shown on drawing in which the accompanying Figure 1 is a fragmentary elevation of a regulator operatively connected to the window glass, some of the parts being broken away for purposes of clarity;

Fig. 2 is a vertical tially on the line 2-2 sectional elevation substanof Fig. 1;

Fig. 3 is a view similar to Fig. 1, showing the position of the parts substantially at the moment when the link is freed from engagement with its retainer or cam track;

Figs. 4, 5 and ing the relative link in various 6 are diagrammatic views showpositions of the crank arm and positions of adjustment, Fig. 4 showing the parts when the window is in raised position, Fig. 5 in an intermediate position similar to Fig. 3, and Fig. 6 in the lowered position of the window.

The illustrated embodiment of the invention comprises a window regulator having a triangularly shaped mounting plate II] which is suitably secured as by bolts and nuts H to a lock board with an inward extension gages the stud l3.

inwardly into an opening an arcuate series of gear which extends transversely Pivotally mounted on the I3 is a crank arm l4 formed l5 which pivotally en- The extension l5 projects l6 which is formed with teeth l'l, forming an internal gear, the teeth of which do not form a complete circle because of the finger extension l5.

Actuating the crank arm I4 is a pinion l8 which meshes with the teeth ll of the internal gear and the pinion l8 is operatively connected to a shaft 19 through a clutch 20, the usual crank handle (not shown) engaging the shaft I9. Detailed description of the clutch 20 is not considered necessary since clutches of this character are old and well-known in the art. Suffice it to say that the clutch 20 enables the handle shaft I!) to be turned in either direction to raise or lower the window but retrograde movement of the pinion I9 is prevented, thereby retaining the window in its adjusted position.

Pivotally connected to one end of the crank arm I4 is a link 2|, the opposite end of the link having a stud or roller 22, carrying a washer which is urged outwardly by a coil spring 23. The roller 22 fits into a horizontally elongate slot or guideway 24, one end of which is enlarged at 25 to enable insertion of the roller. The slot or guideway 24 is formed in a retainer 26 which is fixed to and depends from a channel member 21 which is rigidly secured to the lower edge of the window glass 28.

The link 2| is provided with a laterally projecting pin 29 and when the link is moved into abutment with the crank arm Hi, the pin 29 is adapted to be disposed beneath an arcuately shaped flange 30 of a plate 3| which is fixed to the mounting plate I0. In this manner, thelink f 2| and crank arm M are maintained at a constant angle with respect to each other during a portion of the path of movement of the crank arm. Projecting in opposite directions from the crank arm M are ears 32 which are engaged by the link 2| when the link and arm are moved into engagement. In order to silence the click occasioned by the contact of these parts, a sleeve 33, of rubber or other suitable material, fits over the link and abuts against the ears 32.

Assuming the window glass 28 is in its uppermost or closed position, the parts assume the position shown in Figures 1 and 4. Upon turning the crank handle in a clockwise direction, to impart similar rotation to the pinion I8, the crank arm I4 is swung also in a clockwise direction, the link 2| being retained in its abutting relation to the crank arm by engagement of the pin 29 with the underside of the curved flange track 30. The window glass 28 is thus lowered and during this movement, the stud or roller 22 moves to the right of the figures in the slot or guideway 24. An important feature of this invention resides in so arranging the slot or guideway 24 that when the parts are in the position indicated in Figs. 3 and 5, the roller mobiles and other vehicles and it is found that if the roller 22 abuts against a stop at this point, the window glass can be actuated at a substantially uniform rate of speed. It willbe apparent that upon continued turning of the crank handle, the arm [4 and link 2| will tend to straighten out substantially to the position indicated in Fig. 6 in which the window is open or in its lowered position. It will be apparent that upon turning of the crank handle or pinion I8 in the opposite direction, the above described operation is reversed, the link 2| first operating as a link until it is brought into abutting relation with the .crank arm 14, whereupon these parts act together as a bell crank lever.

It is to be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as defined in the appended claims.

What I claim is: v

1. A vehicle window regulator comprising a crank arm, an internal gear in' said crank arm,

a part of said arm projecting into the approximate center of the space formed by said internal gear, a pivotal mounting for said arm engaging said arm part, a manually operable pinion engaging said internal gear, a link connecting the end of said crank arm to the window, and means to cause said arm and link to act as a bell crank lever during a portion of the path of movement of the arm.

2. A vehicle window regulator comprising a crank arm, an internal gear in said crank arm, a part of said arm projecting into the space formed by said internal gear, a pivotal mounting for said arm engaging said arm part, a manually operable pinion engagingsaid internal gear, a link connecting the end of said crank arm to the window, means to cause said arm and link to act as a bell crank lever during a portion of the path of movement of the arm, and means associated with the window for limiting the relative movement in one direction between the link and arm during another portion of the path of movement of the arm for eifecting movement of the window at a uniform rate of speed.

3. A vehicle window regulator comprising a crank arm, an internal gear in said crank arm, a part of said arm projecting into the space formed by said internal gear, a pivotal mounting for said arm engaging said arm part, a manually operable pinion engaging said internal gear, a link connecting the end of said crank arm to the Window, abutment means on said arm against which said link bears for a portion of the movement ofsaid arm, a rubber sleeve on said link for silencing the contact between said arm and link, means to cause said arm and link of the path of movement of the arm, and means associated with the Window for limiting the relative movement in one direction between the link and arm during another portion of the path of movement of the arm for effecting movement of the window at a uniform rate of speed. I

4. A vehicle window regulator comprisinga crank arm, a link connected to said crank arm, a retainer carried by the window having a horizontally elongate guideway, a stud onthe free end of, said link slidable in said guideway, a pin on said link, a'stationary flanged track for receiving said pin to hold said link against movement relative to said arm thereby to cause .the arm and link to act as a bell crank until said stud is approximately in horizontal alignment with the axis of said arm, and means for actuating said arm, the length of saidguideway being so chosen that said stud abuts against an end thereof substantially prior to the pin entering or upon the pin leaving said track.

5. A vehicle window regulator comprising a crank arm, an internal gear in said arm, a part of said arm projecting into the space formed by said internal gear, a pivotal mounting for said arm engaging said arm part, a manually operable pinion engaging said internal gear, a link connecting the end of the crank arm to the window, and means forming part of the regulator adapted to interengage during a portion of the arm travel for holding said link and arm against relative movement thereby to cause the link and arm to act as a bell crank lever.
