'To all whom it may concern.

Beit known that. I, OSCAR C. GRAFF, a.

' citizen of the United States, residing at which will not loosen under the constant v1- bration and joltingthat it is subject to in a road vehicle. l

In the accompanying drawing Figure 1 is a perspective elevation of my device applied to an unfolded wind shield. Fig. 2 is a perspective elevation of my device, as the same appears with' the wind shield folded. Fig. 3 is a vertical section on the line 33 of Fig..- 1 with parts broken away. Fig. 4 is an end elevation of the wind shield folded showing the lip and tongue engaging 'members, with parts broken away. a a

Referring now; more specifically to the drawing, 4 is the fixed lower frame portion of a wind shield adapted to be secured tothe dashboard of a vehicle or any other suitable part, and 5 is'the foldable frame portion, each of said frame portions being provided with a suitable transparent material 6 such as glass. The upper edge of the frameA is provided with a tongue 7 while the lower edge of the l frame 5 is provided with a groove Sin which the tongue 7 is adapted to be seated, so as to revent lateral or longitudinal movementetween said frame members. As a means' for holding said frame member 5 in an un-., folded position, a bracket 9 is provided which may be formed integral with the frame 4 and which isprovided with two arms '10 and 11.

'At the outer end of arm 11 an eye is formed through which a bolt 12 passes, pivotally securing tosaid arm the'braces 13 and 14, each being provided with an eye through which the bolt 12 passes, arid a threaded nut :15 cooperates with'one endithereof.

The brace 13 is adapted/to be securedv to i the vehicle or the like at any desired point and has no movement relative to'the bracket,

while the brace i i is pivoted to the frame 5 by the: pivot bolt 16 and has a pivotal movement on the bolt 12. The arm 10 is also provided with an eye whereby'a sleeve 1 7 having a threaded shank and a nut 18 adapted to cooperate with the threaded shank, is pivoted to said arm 10'.

Slidably mounted in the sleeve 1 7 is a clamp rod 19; which is-p-ivotcd at oneendto the frame 5 bymeans ef the pivot bolt 20, its other end being threaded to cooperate with a threaded clamp 21, the movement of the ,"clamp rod being/ limited in one direction by the boss 22" on 'one'side of the sleeve and movement in the opposite direction by the clamp 21 on the opposite side of the sleevefrom said boss. A stop screw '23' prevents the clamp from being turned off the clamp rod, while astop flange 24 on the serves both as a guide and a stopfor the -f1a1ne 5 when being placed in an unfolded position.

Referring now 'to Fig. 2, the device is shown in a folded position and in assuming this ositi'on' the clamp is loosened to permit the rame 5 tobe slightly raised to unseat the tongue from the groovewhereupon it may be moved out of the vertical plane of the frame 4 and dropped down, which imparts a pivotal movement to the sleeve and gives the clamp-rod a sliding movement in relation toth'e sleeve. Then the frame 5 has dropped as far as the brace rod 14 and clamp rod 19 will nnit, it is-then in substantially a'vertic 'tion with the tongue 25on the frame 5' low the lip 26 on the frame 4 whereupon by turning the clam 21 the frame 5 is drawn upward and towar the frame 4 bringing the tongue and: lip into enga ement and therebydocking, the wind shield in its folded posit-ion. .'When it is desired tounfold the wind shield the clamp is loosened to disengage the tongue and lip and the frame 5 is then raised to a position. in

substantial vertical alinement with the frame 4 but slightly above the same. By a bracket movement of the clamp down the threads v on the clamp rod the frame 5 is drawn downward interlocking the tongue and groove until the clamp comes in contact with the sleevepvhereupon the parts are firmly locked.

in the preferred" form a pair of brackets and accompanying parts are employed on'a single wind shield although only a single device has been herein described, it is to be preferably used.

understood that two devices may be. and are therefore Without confining myself to the specific detail of construction, I Glfiil'lli' '1. The combination .with a Wind shield having a fixed' ortion and a foldable ortion,

of an adjusta le support for said oldable portion comprising a bracket secured to. the 'Xed portion, a sleeve rotatably mounted in said bracket, a clamp rod slidably engaging said sleeve and pivoted at one end to said foldable portion and a clamp having a tbreadeden gagement with the other end of said clamp-rod whereby a locking or releasing of the cla1nprod is effected.

I 2. The combination with a Wind shield having affixed portion and a foldable portion, of' an adjustable support for said toldable portion comprising a bracket secured to the hired portion, a sleeve rotatablymounted in said bracket, a clamp rod slidably engaging itis obvious that various changes maybe said sleeve and pivoted at one end to said foldable portion, a clamp havinga threaded en agement with the other end of said clam re and a brace pivoted to an to said foldable portion mbstant-ially as described. 4

3L The combination with a wind shield having a fixed ort-ion and a foldable jortion', of an adjustable support -for said 'oldable .plpirtion comprising a bracket secured to the vehicle body, and the other bracevpivotally secured to said arm and to said foldable portion, substantially as described.
