12' Claims.

This invention relates generally to windshield regulators and consists of certain novel features of construction, combinations and arrangements of parts that will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a perspective view of a windshield regulator embodying my invention applied to a w gvindshield and showing the latter in open posiion;

Figure 2 is a view similar to Figure 1 but showing the windshield in closed position;

Figure 3 is a horizontal longitudinal sectional view therethrough;

Figure 4 is a bottom plan view of the regulator;

Figure 5 is a fragmentary sectional view taken on the line 55 of Figure 1.

Referring now to the drawings, A and B respectively are toggle links for moving the lower edge of a hingedly mounted windshield such as C forwardly and rearwardly relative to a transversely extending flange or rib portion D of a vehicle cowl E; F and G respectively are upright posts for swinging the arms A and B; H and I respectively are gear sectors projecting laterally from the posts; J is a horizontal stub shaft having a worm K meshing with the gear sectors H and I and adapted upon being rotated to cause the posts F and G to turn; L is a crank or operating member, and M is a frame attachable to a depending portion or apron N of the cowl and constituting a common support for the regulator parts aforesaid. Preferably the windshield C is provided at spaced points of its lower edge with rearwardly extending lugs 1 and 2, while the posts F and G are provided at their upper ends with heads 3 and 4 respectively having spaced upwardly extending lugs or ears 5. The outer sections 6 and '7 of the links A and B are pivotally connected to the lugs 1 and 2 while the inner sections 8 and 9 of the links are connected to hinge pins 10 and 11 respectively extending through the lugs or ears 5. Preferably the inner sections 8 and 9 of the links are also provided adjacent the hinge pins 10 and 11 with struckout tongues 12 and 13 respectively that engage the lugs 5 and prevent the links from wabbling or rattling while in use.

In the present instance the gear sectors H and I are formed integral with .the posts F and G respectively. In fact, the post F, head 3 and gear sector H is preferably a die casting, while the post G, head 1 and gear sector I is another die casting. Thus a minimum of parts are employed and the manufacturing costs have been according opposed bearing portions 19 and 20 respec tively for th shaft J, opposed bearing portions 21 and 22 respectively for the posts F and G, opposed trough-shaped portions 23- and 24 respectively, opposed slots 25 and 26 respectively for the gear sectors H and I, overlapping attaching portions 27 and 28 respectively and overlapping brace portions 29 and 30 respectively. Preferably the opposed bearing portions 19 and 20 for the shaft J receive the flange portions 14 and 15, while the opposed bearing portions 21 and 22 for the posts F and G are constructed in such a way that spaces 31 and 32 respectively are provided upon the inner sides of the posts to permit such posts and the gear sectors H and I integral therewith to shift toward the shaft J to compensate for wear. Suitable followers 33 and 34 respectively and springs 35 and 36 are provided in the opposed trough-shaped portions 24 between the far ends 37 and 38 thereof and the gear sectors H and I for taking up the slack and maintaining the proper engagement between said gear sectors and worm K.

In use the windshield C may be opened or closed as desired by simply turning the crank L. The hinge connections between the heads 3 and 4 of the posts and the inner sections 8 and 9 respectively of the toggle links permit the latter to assume an inclined position while the windshield is open and enables the opening and closing thereof to be effected without any binding action. In this connection it will be noted that the tongues 12 and 13 struck-out from the link sections 8 and 9 will ride upon the lugs 5 when the sections swing about the hinge pins 10 and 11 and will hold the parts against rattling or wabbling. The springs 35 and 36 constantly urge the posts F and G toward the shaft J so that the proper engagement between the gear sectors H and I and worm K will be maintained at all times. Such springs not only take up the slack but also hold the parts in the frame against rattling.

Thus from the foregoing description it will be readily apparent that I have provided an extremely efficient regulator that is simple in construction, comparatively inexpensive to manufacture, and easy to install and operate.

What I claim as my invention is:

1, In a windshield regulator, a supporting frame, an operating member carried by the frame, and means operable by said member for actuating a windshield including a post mounted to turn in the frame and having a head provided with'spaced lugs, ahinge pin extending through said lugs, and a laterally projecting member having a substantially tubular portion on the pin between the lugs and having struck-out portions engaging the lugs to prevent the member from wabbling and/or rattling.

2. In a windshield regulator, a supporting frame, an operating member carried by the frame, and means operable by said member for actuating a windshield including a post mounted to turn in the frame and having a head provided with spaced lugs, a hinge pin extending through said lugs, and having means engageable with the lugs in all positions of the member for preventing the said member from wabbling and/or rattling.

3. In a windshield regulator, a supporting frame formed of sheet metal and comprising two complementary sections having opposed bearin portions for an operating shaft, and opposed hearing portions for the rotary post, said last named portions forming elongated slots permitting the post to shift laterally relative to the bearings for said shaft to compensate for wear.

4. In combination, a swinging windshield, a substantially horizontal abutment therefor, and actuating means for the windshield carried by the abutment and including a post mounted to turn about a substantially vertical axis, a lug rigid with and projecting rearwardly from the inner side of the windshield at the lower free edge thereof, and a pair of pivotally connected links pivotally connected to said post and lug, the connection between one of said links and the post including a pivot pin disposed at substantially right angles to the axis of the post and permitting both of said links to move from a position substantially at right angles to the post to a position substantially at an obtuse angle to the post, and the connection between the other of said links and the lug including a pivot element substantially parallel to the inner side of said windshield.
