HARVEY G. SMITH, 0F LOS ANGELES, CALIFORNIA.

WINnsHIELD.

citizen of the United States, residing 'at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Windshields,.of which the following is a complete specification. l

My invention relates to that class of wind-shields known as auxiliary or wing wind-shields, which are intended to be attached to each side of the ordinary windshield of a vehicle, and the object of my improvement is to provide a wind-shield which is capable of universal adjustment and to provide one which can be folded back against the main wind-shield without striking the body or door of the vehicle. Another purpose in my improvement is to provide a wind-shield which is capable of vbeing rotated in a vertical plane and locked in that position'so that a V-shaped opening is provided between the ordinary wind-shield and the wing shield thus allowing a clear vision in snow or rain storms and still reducing the` draft to aminimum. I attain these objects by the mechanism illustrated Vin the accompanying drawingsin which: Figure 1 is a plan view of my device attached to an ordi-- nary wind-shield, the latter'and also part of the attachment being shown in section.

F ig. 2 is a side elevation with the clamp screws removed and the corrugations of the rotary clamp shown. Fig. 3 is an end elevation. Fig. 4 is an isometric view of the device showing slight modiiications in design and with diagrammatic arrows to clearly illustrate the vdirection of all possible adjustmentsz Similar letters and figures refer to similar parts in the several views. Al is the frame and G the glass of the ordinary wind-shield. 1 and 2 are 'the separate members of an adjustable bracket adapted to be clamped to the frame A by the screws 3. Integral with the member 2 and at rightangles to its axis is a circular bracket 4 having on its outer face the corrugations 5 and being also provided with a raised boss 6 adapted to engage with a recess on the adjacent disk 7 and for the purpose of both centering same and of taking the shearing stress on same. The circular bracket or lug 4 is also provided with a tapped hole to receive the clamp screw 8. The clampidisk Specification of Letters `Patent.

7 is provided with corrugations on its inner surface'which are adapted Ito engage with the corrugations 5 and a hole adapted to register with the raised boss 6 ofthe lug 4. Integral with the clamp disk 7 and extending out from it on one side is the vertical bracket 9. This bracket is provided with a at rightangles to .hole 10 having its aXls that of the disk 7 and is also provided with split clamp-lugs 11 and a clamp-screw 12 by which the 'rod 13 may be adjustably clamped therein. The rod 13 isprovided with screw threads at each end. Adapted to be screwed on to each end of the rod 13 are the slotted arms 14, the said arms 14 being adjusted and locked in position on the rod 13 by the lock nuts 15. If desired the arms 14 may have a plain bearing on the rod 13 instead of the tapped'hole, thus allowing a swinging adjustment without changing the distance between the said arms 14. The glass auxiliary wind-'shield 16 is provided with lugs 17 which may be cemented on the glass as shown, or they may be bolted to the glass through holes for the purpose. The lugs 17 have trunnion pins 18 which are adapted to fit the slots 1'9 in the arms 14. The ends of these trunnion pins are threaded and are provided with the clamp-nuts 20 which lock the glass and trunnion pins in both lateral and rotative position on the .arms 14.

In the alternative construction shown in Fig. 4 the vertical bracket 9 is not split but is provided with a separate clamping plate 9a... In place of the rod 13 and the slotted arms 14, the rod 21 is provided, the same being bent to three sides of a rectangle. Adapted to slide and clamp on the horizontal arms of the rod 21 are the tubular brackets 22, which are provided with an offset vvertical lug 23 adapted to receive the trunnion pins 18, the said pins being locked by the same clamp-nuts 20 as in the construc- `tion shown in Fi s. 1, 2 and 3. If desired the tubular .braclrets 22 may be split or sawed through on one side so that they will be tightly clamped onthe arms of the rod 21 by the action of the clamp-nuts 20.

The operation of my device is as follows: The brackets 1 and 2 are first clamped on the main wind-shield frame A, being located in any desired position and securedby tightening the screws 3. The rod 13 or the with the 'rod 21 is used. The clamp disk 7 carrying with it the glass 16, arms 14 and rod 13 or 21 is lthen assembledon the circular bracket 4: in position' over the boss 6 an secured by the clamp-nut 8. l

The operation of the assembled mechanism is clearly shown in Fig. 4 in which the arrow B' shows the direction of rotative movement; the arrow C the vertical adjustment of. the rods 13 our 21; the arrow the horizontal swin 'ng movement; the arrow E the lateral adjustment of the auxiliary wind-shield on the arms 14 or onthe rod 21; the arrow F the rotative adjustment of the auxiliary wind-shield on the trunnion pins 18. It will benoted that my device can be applied to existing auxiliary wind- 'shield lasses, their varying size being accommo ated bythe adjustments ofthe spacing of the arms -14 on the rod 13. Special forms. of the lugs 17 may be provided for glasses-A which are not rectangular or are otherwise diiferent from' the form shown.

What I claim as my invention and desire to secure by Letters Patent is :d 1. In an auxiliary wind-shield a clamp adapted to be attached to a vehicle, a pivot lug integral with said clamp, a bracket revolubly mounted thereon, corrugations on the adjacent faces of said lug and said bracket, a rod mounted in said bracket and capable of rotative and longitudinal adjustment, means for lockin said rod, slotted arms adjustably mounte at the extremities ofsaid rod, a wind-shield revolubly mounted on trunnions capable of being adjusted and-locked in said slots in said arms; all substantially asshown and described.
