UNITED STATES ANGELO ROBERT CLAS, OF TOLEDO, OE' IO.

WINDOW-REGULATING APPARATUS.

Application filed November 18, 1922. Serial No. 800,788.

To all whom it may concern:

Be it known that I, ANGELO ROBERT OLAS, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have made an invention appertaining to a Window-Regulating Aparatus; and I do hereby declare the followmg to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to window regulating apparatus particularly intended for use in closed automobiles and other closed vehicles.

The object of the invention is the provision of a simple and efficient apparatus of the character described, which is easily operable to raise and lower an associated window, is adapted to positively lock a window against accidental lowering when in any position of adjustment, is composed of a few easily accessible parts, and is free from rattles.

The invention is fully described in the following specification, and while in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is an inner side elevation of an automobile door embodying the invention with the upholstering removed, the window in partly lowered position, and with portions broken away. Fig. 2 is a vertical section on the line 22 in Fig. 1. Fig. 3 is an enlarged cross-section on the line 3-3 in Fig. 2. Fig. 4 is a vertical section on the line 4-4 in Fig. 3, with a portion broken away. Fig. 5' is'a perspective view of a portion of one of the ratchet channel strips, and Fig. 6 is a cross-section on the line 6-6 in Fig. 4.

Referring to the drawings, 1 designates an automobile door having in its upper portion a window opening 2 and provided with a closure for said. opening in the nature of a vertically slidable glass plate 3 adapted, when lowered or removed to its open position, to enter a chamber 4 in the lower portion of the door. The window is guided at its side edges by channel strips 5 of felt or other suitable material adapted to prevent rattling of the glass, and these strips are set into recesses provided therefor longitudinally in the upright frame members or casing sides 6 of the door.

The glass plate 3 fits at its lower edge into a metal channel strip 7, as is customary in w ndows of this type, the ends of the strip termmating short of the side guide strips 5 for the plate. An ear 8 is fixed to and projects downwardly from the edge strip 7 centrally of its ends and a cable 9 is anchored at one end to the ear, thence extends upward therefrom over a sheave 10 carried withln the upper portion of the chamber 4 by a cross frame part 11 of the door, the cable extending downward from the sheaves and attaching at its opposite end to the free end of a counter-balancin lever 12, which is pivoted at one end to a racket 13 secured to one of the frame sides 6 near its lower end. The lever 12 extends across the chamber 4 substantially in a vertical plane with the lower edge of the window plate 3 and is acted on by a coiled contractile spring 14 to counter-balance the weight of the window plate 4. The upper end of the spring 13 is adapted to be placed in engagement at its upper end with any one of a plurality of notches 15 in the lever to adjust the tension of the spring with respect to the lever, and the lower end of the springis anchored to the cross-member forming the bottom of the chamber 4. This counter-balancing means for the window plate is very efficient as the counter-balancing pressure of the same against the plate is constantly exerted against the lower edge of the plate at its central portion, thereby eliminating any tendency of the counter-balancing means to exert a lateral pressure on the plate to cause a binding of the same in its guides.

Each side frame upright 6 of the door or window casing, as the case may be, is provided longitudinally thereof at the inner side of the respective guide strip 5 with a channel 16, which opens at what may be termed its outer side to the window opening 2 and the chamber 4. A channel strip 17 preferably of metal, is .fitted into each frame bar channel or recess 16, or at least the portion thereof which opens into the window opening 2, and preferably extends a distance down into the portion of the frame bar channel which opens into the chamber 4. The inner side of each channel strip 17 is provided longitudinally thereof with a series of ratchet openings or notches 18, while the outer side of the strip is provided with a longitudinally extending opening or slot 19, which is restricted with respect to the width of the channel strip by an inward turning of the terminal edge portions of the channel strips. This provides a ratchet strip of channeled or hollow form, which is substantially rectangular in crosssection and provided longitudinally thereof in its inner or rear wall with .a set of ratchet openings or notches 18, and in 1ts front or outer wall with a slot or elongated opening 19.

The binding strip 7 for the lower edge of the window-plate 3 has an ear 20 rigidly projecting from each end thereof into the adjacent door frame channel 16 and also into the associated ratchet strip 17 through the front opening 19 thereof, should the ratchet strip extend down into the channel 16 a sufii'cientdistance for such purpose. A

control or liftin rod 21 is mounted longitudinally in each ratchet strip 17 and has its lower end pivotally connected to the adjacent car 20 of the window plate 3 for limited rocking movements in a planeparallel or substantially parallel to the face of the plate 3. The mounting of the control rods 21 in this manner enables them to have inner and outer locking'movements relative to the ratchet strips 17- or transversely of the window and within the confines of the ratchet strips.

Each control bar 21 is provided at the inner side of its upper end portion with a pawl or tooth member 22 for engagement within any one of the ratchet openings 18 with which it may register to coact with the lower wall of the opening to support the control rod in any position of its vertical adjustment within the ratchet'strip. The tool 22 is preferably carried by a stem 23. which pro ects outwardly through the associated rod 21 and the ratchet strip 19 and is provided at its outer end without the ratchet strip with a handle 24. A spring 25, preferably of bowed form, is disposed between the upper end portion of each control rod 21 and the outer slotted wall of the associated ratchet strip 17 and acts to normally urge the upper end of the control rod toward the inner side of the ratchet strip and to retain the tooth 22 in engagement with a ratchetopening, as is apparent.

- To raise or lower the window plate 3 it is only necessary for the operator to grasp the control handles 24 at each side of the window casing and draw them outwardly to efl'ct an outward rocking of the control rods 21 against the tension of the springs 25 and a consequent withdrawal of the ratchet teeth 22 from the engaged ratchet openings, after which a raising or lowering force exerted on the handles 24 will impart a corresponding raising or lowering moveesa-lea ment to the window plate. If the ratchet teeth 22 are of the beveled face type, as

shown in the drawings, the window ma raised without first moving the control andles to withdraw the teeth from the ratchet openings, as is apparent.

I wish it understood that my invention is not limited to any specific construction, arrangement, or form of the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claims. and also that while I have particularly shown and described the window regulating -means in amociation with a door, it may be applied to any window casing.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-

window member mounted for raising and lowering movements in the casing, a control member disposed lengthwise of the window member and pivoted thereto, said control member having a tooth near its free end, and ratchet means carried by the casing for coaction with the control member tooth to support the control and window members in difi'erent positions of vertical adjustment.

2. In combination, a window casing, a window member mounted for raising and lowering movements in the casing, a control member disposed lengthwise of the window member and pivoted thereto for rocking movements in the plane of the window, said control member having a tooth near its free end, ratchet means carried by the casing for coaction with'the control member tooth to support the control and window members in different positions of vertical adjustment, and spring means acting on the control member to normally hold it in position for ber of said means being pivoted to the window member and extending therefrom lengthwise of the casing along the ratchet member of the means.

4. In combination, a window casing, a window member mounted for raising and lowering movements in the casing, and pawl and ratchet means connecting the casing and window member, the ratchet member of said means being carried by the casing and extending lengthwise of a side portion thereof and the pawl member of said means comprising a rod extending lengthwise of the casing adjacent to a side edge of the window and pivoted at one end to the window and having a tooth adjacent to its other end for engagement with the ratchet member of said means.

5. In combination, a Window casing, a window member mounted for raising and lowering movements in the casing, a chan neled ratchet strip carried by the casing lengthwise of the window member and adjacent to a side edge thereof, a control member mounted in the. ratchet strip lengthwise thereof and having one end pivoted to an adjacent edge of the window member and having a tooth adjacent to its other end portion for holding engagement with the ratchet strip. 7

6. In combination, a window casing, a window member mounted for raising and lowering movements in the casing, a channeled ratchet strip carried by the casing lengthwise of the window'membermand adjacent to a side edge thereof, a control memedge portion 0 ratchet strip, and means within the ratchet strip and acting on the control member to normally retain its tooth in holding engagement with the ratchet strip.

7 In combination, a window casing, a window member mounted for raising and lowering movements in the casing, an elongated hollow ratchet strip mounted in a side of the casing lengthwise thereof and having ratchet teeth in one side and an elongated longitudinally extending opening in its opposite side. a control rod mounted in the ratchet strip lengthwise thereof and having one end fpivoted to an adjacent side the window member for locking movements transversely of the ratchet strip, said rod having a tooth near its free end portion for engagement with the ratchet teeth and having a handle part projecting without the ratchet strip to the elongated opening therein, and means acting on the control bar within the ratchet strip to normally retain the control bar ber mounted in the ratchet strip lengtl'lwise tooth in holding engagement with a registhereof and having one end pivoted to an adjacent edge of the window member and having a tooth adjacent to its other end portion for holding engagement with the te'ring ratchet tooth.

In testimony whereof I have hereunto subscribed my name to this specification. ANGELO ROBERT CLAS.
