tachments, and more particularly to an at' tachment designed to protect the operators line of vision from the glare of light rays from lamps of approaching vehicles, or fromy the suns rays.

Another object ofthe invention is to provide a device of this character which may be operated by the suction of the pistons working in the cylinders of the motor, novel means being provided to control the suction through the pipe connecting the engine cylinders and cylinder'of the screen.

A still further object of the invention is the provision of a protector which may be applied to the usual motor vehicle construction, eliminating the necessity of making ex- .tensive alterations to apply the device.

With the foregoing and other objects in view which willappear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction ,hereinafter described and claimed, it being understood tha-tv changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawingz- Figure 1 is a fragmental elevational view lof 'a wind shield disclosing an attachment constructed in accordance with the present invention applied thereto. y

Figure 2 is an end elevational view thereof.

Figure 3 is a sectional view through the cylinder forming a part of the structure.

Figure 4 is an elevational view of the valve, the valve housing being shown in sec tion.

Figure 5 is a sectional view taken on the .line 5-5 of Figure 4. y

Referring to the drawing in detail, the reference character 5 designates a portion of a body of a vehicle, the showing illustra-ting that portion ofthe vehicle body which supports the wind shield frame 6. The wind shield is designated .by the reference character 7, the protector being shown as supported adjacent .to .the upper edge thereof.k

The attachmentjembodies a tubular member 8 which carries hook members 9 adapted l to lit over the frame of the upper section of a Wind shield as clearly shown by Figure 1 of the drawing. lVithin this tubular member 8 is positioned the screening member 10 or guard, which is in the form of a curtain constructed of a suitable translucent material and designed to be wound on the roller 11 which is spring controlled, to return the curtain or guard to its normal position within the tubular member 8.

Disposed adjacent to one end of the tubular member 8 is a vertically disposed cylinder. 12 which has its upper end secured to one end of the tubular member 8 in any well known manner. Operating within the cylinder- 12 is a piston 13 which has connection with the flexible member 14 that has one end thereof connected to the vcurtain or guard 10, l

Vthe intermediate portion operatingover the manifold of the internal combustion engine not shown, as through the, pipe 18, whereupon the suctioncreated by the pistons moving lwithin their cyinders will establish a vacuum within the pipe 17 to the end that the piston 13 is moved to the upper extremity of the cylinder 12, moving the curtain or bar 10 to its lowermost position to guard the line of vision of the operator.

This valve`housing 16 is formed with 'an exhaust 'opening 19, whereupon when the valve member 20 is in its normal position,

air may enter the pipe 17 to relieve the ,vac-

uum within the cylinder 12, to the end that the coiled spring, not shown, but which forms a part of the roller 11, will return the curtain or guard, to a position within the tubular member 8.

As shown, the valve member 20`is formed with a circumferential roove 21 formed adjacent to the lower end t ereof, which groove spring it, will member 20 munication between the pipes 18 and 17 asthe upper edge of a win wardly to establish communication between pipes 15 and 17, one portion of the valve member 20 moves over the )opening 19 to close the same. A coiled spring is interposed between the bottom wall of the valve housing 16 and the base of the valve member 20, the spring being indicated at 21. This be seen normally urges the valve member 20 to the limit of its uppermost position, to the end that the vacuum within pipe 17 is normally relieved.

When the operator desires to cause the guard or screen 1() to move to its active position, itis onl necessary to force the valve ownwardly to establish comdescribed.

Having thus described the invention, what is claimed as lnew is 1. A Windshield wiper including a housing, 'means for positionin the housing over shield, a cylinder supported ad] acentto the housing, a piston movable in the cylinder, a curtain adapted to be wound within the` housing, flexible means for connecting the curtain and piston, whereby movement of the piston results in a relative movement of the curtain, to move the curtain with respect to the Windshield, a pipe having communication with the cylinder, and avalve member for controlling the passage of air to and from the cylinder.

2. A movable screen for windshields including a cylinder, suction controlled means movable within the cylinder ormoving the screen to its active position, a valve housing, a pipe establishing communication between the valve housing and cylinder, said valve housing having an exhaust opening, an intake plpe extending into the valve housing at a point in the irst mentioned pipe, a vertically movable valve member having a circumferential groove adapted to normally register with the exhaust opening, said valve member adapted to be moved to provide communica,- tion between the inlet pipe and first mentioned pipe, and simultaneously cut off the exhaust opening"'and a coiled spring for normally urging the valve member to its inactive position.

In testimony, that we claim the foregoing as our own, we have hereto alii-Xed our signatures in the presence of' two witnesses.
