WIND-SHIELD.

Specification of Letters Patent.

Patented Jan. ii, ieie.

Application filed March 6, 1911. Serial No. 612,674.

To all whom, it may concern:

Be it known that I, EDWARD L. ACKER- MAN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Wind-Shields, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to wind-shields and resides in the peculiar construction, arrangement and combination of the means for locking the sections against relative movement in an adjusted position, and in the peculiar construction, arrangement and combination of parts as more fully hereinafter described and particularly pointed out in the claims.

1n the drawings, Figure 1 is a fragmentary perspective view of a shield embodying my invention, illustrating the manner of attaching the same to the vehicle;Fig. 2 is a side elevation of the structure shown in Fig. 1; Figs. 3, 4, 5, 6 and 7 are perspective views of certain parts of the rotary lock and the pivotal connection for the shield; Fig. 8 is a central vertical section through the rotary lock; and, Fig. 9 is a similar view of the pivotal connection for the movable section.

A represents the dash of the vehicle, and 13 standards or vertical rods arranged upon opposite sides of the dash and rigidly attached at their lower ends to the vehicle frame as at C.

A is the movable shield section, which may be of any suitable construction and which is pivotally secured at its opposite side edges to the upper ends of the standards B. The pivotal connection'at each side of the shield section comprises a pair of complementary disk members 1) and E attached respectively to the side of the shield section adjacent the bottom edge thereof and to the upper end of the standard, the disk D being mounted for rotary movement upon a bolt or pin F carried by the complementary disk member. One of the disks, as L, isprovided with a recessed portion G and the other with a cooperating projection H adapted to fit within the recessed portion G which not only serves to properly position the disks in relation to each other, but also relieves the pivot pin of a portion of the torsional strains that necessarily it is subjected to. If desired, one or more washers such as the fibrous members I, may be interposed between the disks, the washers being of a diameter to fit within the space bounded by the circular projection and the recessed portion.

J are brace rods for the members B, each of which is secured to the vehicle frame at its lower ends, as at K, and has the opposite end'attached to an eye L formed integral with and projecting laterally from the disk E, carried by the standard.

The locking means for retaining the shield in its different positions of adjustment is so constructed as to permit the same to extend forwardly of the dash in its lowered position, and furthermore, is so arranged as to form a brace for the shield both in its extended and folded positions. Pref erably though not necessarily, two locking devices are employed, arranged respectively upon opposite sides of the shield. As the locking devices are of similar constructions, one only will be described in detail. Thus M is a rod formed of two telescopic sections N and U, and P an eye upon the outer end of the section N pivotally engaging a lug Q projecting laterally from a bracket .tt which is connected to the standard.

S designates a rotary lock comprising relative rotary members T and U secured respectively to the outer end of the telescopic section 0 and to the side of the shield, and so constructed as to automatically interlock. A shown, the member U is provided with an annular projection V which engages a complementary recessed portion W of the member T. This latter member is pivoted upon a bolt W passing through alining apertures in the members T and U and having the outer end it thereof extending within a housing formed by a hollow lateral enlargement X of the member T. The members T and U are yieldably pressed toward each other-by means of a coil spring Y which is sleeved upon the end of the bolt W" extending within the lateral enlargement, and has its opposite ends bearing upon the base 1) of the enlargement and a washer V locked upon the end of the bolt W by a pin Z.

A is a cap for closing the outer end of the housing.

Positioned at substantially diametrical points upon opposite sides of the circular projection V and in close proximity thereto, are lateral extensions B and C each of which is provided with a central grooved recess Y, a stop-lug Z and a cam D, the stop-lug and cam being arranged upon opposite sides of the curved port-ion. The cam of one of the extensions is however, positioned upon the side of its respective curved portion corresponding to the position of the stop-lug of the other extension, as will be readily seen from Fig. 2.

D and E are lugs arranged upon opposite sides of the recessed portion IV and which have curved faces F. and Gr adapted to -have an automatic locking engagement with the curved recesses Y.

Assuming that the shield is in the position shown in dotted, lines in Fig. 2, during the raising thereof to its extended position, the curved faces F and G will cause the lugs D and E to ride up the cams of the extensions B and C, separating the members T and U against the tension of the spring Y and permit the lugs D and E to engage the curved recess. In this position the stop lugs Z abut against said lugs D and E, but upon opposite sides thereof. The outer face of the member E is also provided with a cam H having a curved portion or seat I shaped to engage the rod, and during the straightening of the upper section, the rod is brought into engagement with the curved seat I forming a rigid connection for holding the rod against lateral movement. The tension of thespring Y is sufficient to pre vent displacement of the rod from the curved portion I of the lugs D and E and from the curved recess Y against normal strain, but when it is desired to lower the shield section a quick pull or jerk upon the same adjacent the upper edge thereof 'will cause the lugs D and E and the rod M to ride up the curved recesses Y and I and out of engagement therewith.

In the folded position of the shield the telescopic rod forms a support therefor and the shield is held against oscillation by the rotary lock. As shown in dotted lines in Fig. 2 the lugs D and E are so positioned as to engage the outer edges of the extensions B and C but upon opposite sides thereof, the tension of the spring being suiticient to normally prevent the lugs from riding up the cam faces of the extensions. I may and preferably do provide the inner end of the telescopic section 0 with a yielding bearing block, such as the member J formed of rubber, which in the folded position of the shield abuts against the bottom L of the outer telescopic section N and serves as a buffer for the inner telescopic section. It will be readily seen that by locking the rod M at spaced points considerable rigiditv is given to the upper section.

The pin IV is preferably held in proper relation to the member U by forming a counter-sink A upon the inner face of said 'A'recess C is also formed in the outer face of the member E so that the head I) of the pin F will not project outwardly beyond the seat I.

What I claim as my invention is:

1. In a wind shield, the combination with a supporting section, of a movable wind shield section pivotally connected directly to said supporting section at the upper end thereof, and .a rod having its ends connected respectively to said sections and pivoted to turn in relation thereto, and an automatic lock for locking the rod in an adjusted position of the movable shield section comprising cooperating interlocking portions respectively upon one of the sections and an intermediate portion of the rod.
