WIND-SHIELD.
Specification of Letters Patent.
Patented Oct. 1'7, 1905.
Application filed May 27.1905. Serial No. 262,642.
f0 (ti/l whom it may concern.-
Be it known that I, JOSEPH EYssE'RIo, a citizen of the French Republic, residing at (Jarpentras, in the Department of la Vancluse, France, have invented new and useful Improvements in Wind-Shields, of which the following is a specification.
This invention relates to a wind-shield which is applicable to any kind of vehicle or to a boat or ship.
The object of the invention is to divert the horizontal current of air due to the speed of the vehicle or the like or to a head-wind and to divert it to pass above the head of the driver or observer.
An improved wind-shield which is given as an example and is constructed according to this invention is illustrated in'the following drawings, in which- Figure 1 shows it in side view as attached to a motor-car. Fig. 2 shows the same device in front elevation. Fig. 3 illustrates in more detailed side view an adjustable supplementary part employed to increase the area of the shielding-surface.
The improved shield, which is essentially an apron, is fixed to the lower part of the car by an adjustable bracket, (shown at a.)
The main part of the shield consists of two curved portions, viz: first, one, 6 0, whose chord forms an angle of about forty-five degrees with the horizontal; second, an upper second part 0 (Z, struck to a smaller radius,.
(about from fifteen to twenty centimeters.) This second part is angularly adjustable, so that it is possible to vary the angle of a tangent struck from its upper edge, as is hereinafter Further, an additional adjustable part permits the surface of the upper portion of the shield to have its area varied. This adjustable part (indicated at (Z 6) is concentric with the part 0 (Z and may be slid thereon to effect the necessary variation of area of surface of the upper part of the shield. The angle of the tangent referred to and as shown in Fig. 1 is about at ninety degrees with the horizontal.
The portion 7) c of the shield may be cut out or notched to allow the entrance of part of the steering-wheel, the opening so formed being covered with a hood f.
With the apparatus constructed as described and in use and with the upper portion disposed with its tangent as indicated at d in the proper direction there is produced behind the upper part of the shield a region of calm air the vertical section of which approximately follows a parabolic curve; but in its.
well in front of his car and at the same time be protected. It has therefore been necessary to extend the shielded region. sired result has been attained by the addition of a further part b g to the lower part b 0 of the shield, but of smaller depth than this lower part and fixed parallel to the main surface at a distance of about ten centimeters. The parallelism of'these two parts is essential to efficiency.
The part c d must have its inclination varied more or less according to the conditions under which it is working. It has therefore been made movable around the hinge 2'. (See Fig. 3, in which figure the upper part is shown in greater detail.)
WVhen the part shown at d. Fig. 1, occupies the position indicated at (Z in Fig. 3, the tangent before referred to will be atan angle of about forty-five degrees with the horizontal, and this position is convenient for use with slow speeds. l/Vith the same part in the position indicated at (Z, Fig. 3, the tengent is at about sixty degrees with the horizontal. This position is suitable for average speeds of from fifty to fifty-five kilometers an hour. When the part (Z is moved back to the position (1'' in Fig. 3, the shield is in the position for use with high speeds.
As before explained, to the part 0 d may be added a second concentric surface, which lies upon the surface cal and may be movable thereon to increase or diminish at will the height of this part. This second surface is indicated by the broken lines in Fig. 3, and it may be secured in place by winged nuts or equivalents. There are two ways of varying the angle of the trangent to the upper edge of 0 (Z, either by angularly moving the part indicated in the full lines to the positions d d cl or by extending or moving the second concentric surface, as shown in the dotted lines. The angle of the tangent to the hori- The dezontal (if) is thus variable form forty-five degrees to ninety degrees.
In the are at 7r: It" in are indicated the centers of the curve of the part 0 (Z in its various positions.
For the better understanding of the drawings the extra sliding piece and its thumbshield, and a supplementary curved plate attached to the main lower part of the shield and parallel therewith, all substantially as hereinbefore described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOSEPH EYssERIc.
