WIPEH Filed Aug. 31, 1929 7 111 732 Jo n :4 6 h C d Patented Apr. 12, 1932 UNITED STATES JOHN W. ANDERSON, OF GARY, INDLQNL WIPEB.

Application filed August 31, 1929. Serial 10.389353.

My invention belongs to that eneral class of devices known as windshiel wipers or squeegees and relates more'particularly to an improved type of wiper blade or swipe, as it is generally known.

The invention has among its objects the production of a simple, durable, eflicient, inexpensi ve and satisfactory device of the kind described for use wherever found applicable.

' be less inclined to smear and will not be rendered inoperative or ineflicient through the accumulation of snow, ice, dirt or mud on, or in itself, the same being substantially selfcleaning at all times.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a side elevation of my improved applied to a windshield glass;

wiper ig. 2 is an enlarged sectional view taken substantially on the line 22 of Fig. 1;

Fig. 3 is the same view of the blade in operative relation with the surface to be Wi ed; and

ig. 4 is a perspective view of a ortion of the rubber strip. p

Referring to the drawings in which a preferred embodiment of the invention is shown, it may be mentioned that the blade is an improvement in the type illustrated in my pending application, Serial No. 337,041, and consists of a blade preferably of rubber consisting of a body part provided with a head having a plurality of arrises extendin from end to end thereof. I have designate the blade generally by the numeral 1, the same consisting of a body part 2, rovided with a rib or enlarged rib 3 extending along the back or rear edge thereof. The opposite edge of the body part 2 is enlarged as indicated at 4 and provided with the shoulder portions 5. At this edge there is provided the head 6, which is connected to the body part or edge 4 by a hinge portion 7 of reduced size, so that the same is comparativel flexible and constitutes a hinge whereby t e head portion may be flexed from one side to the other for example as shown in Fig. 3. The head is comparatively thick so that in itself it does not flex or yield to any extent, other than to closel hu the surface to be wiped and is provide wit arrises 8, substantially similar to those shown in my pending application referred to.

The blade 1 is mounted in a holder 9 which consists of a channel or U-shaped member preferably formed with an enlarged loop at the closed side with the outer ends flared as indicated at 11, so as to closely fit the body portion 2, and of a width or size so as to engage at the shoulders the edge portion 4 of the body. The blade is adapted to be moved over a surface to be wi ed or squeegeed as for example the outer ace of a windshield glass 12, it being immaterial whether the blade 'is moved back and forth in a. straight line or moved in an are by means of a spring arm carried by a rock shaft. For purposes of illustration, I have shown the last mentioned type of actuating means, which 16 re resents the arm that swings back and fort As shown the holder 9 is provided with an through the rubber blade. A clamping member is secured by a bolt 17 and nut 18 and connects the holder with the arm 16. As

opening 14 which opening also extends As the device is moved back and forth over the surface to be wiped the blade is flexed back and forth at the hinge portion 7, there being also some slight play between holder and the sides 19 of the clamp. The head 6 is at all times maintained in contact with the face to be wiped and maintains uniform engagement therewith regardless of variations, in the surface or lack of careful fitting of the clamps, etc., so the wiping tends always to be uniform and even. Obviously no dirt, snow, or thelike can get in between the holder and the wiping blade, and the blade is firmly held in place in the holder. Should any water, dirt, snow or ice get in the space 7' adjacent the hinge, the head working back and forth during the flexing of the hinge portion causes the same to drop out and the device thus cleans itself. It will be noted that the shoulders formed at 55 form a stop for the head and these also at all times prevent the metal edge of the holder coming in contact with the glass or surface wiped. The device is inexpensive to manufacture and is applicable on practically any type of wiper or squeegee and has a comparatively long life in use.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. A flexible wiping element for a squeegee, consisting of a body part provided with a rib on one edge of greater thickness than the adjacent body portion, and with a head on the opposite edge, said head and body being integrally connected together by a hinge portion of a thickness less than the thickness of the adjacent body and head, whereby the head may be flexed back and forth at the hinge, the body portion constituting a stop for the head remote from said hinge portion, thereby limiting the movement of the head when flexed to either side.

2. A flexible wiping element for a squeegee, consisting of a body part provided with enlarged rib portion on one edge of a greater thickness than the adjacent body portion, and with a head on the opposite edge, said head and body being integrally connected together by a hinge portion of a thickness less than the thickness of the adjacent body and head, whereby the head may be flexed back and forth at the hinge, the body portion constituting a stop for the head remote from said hinge portion, thereby limiting the movement of the head when flexed to either side, the head tapering outwardly from the edge at the juncture with the hinge, and provided with a plurality of wiping edges.

Patent dated April 12, 193

As the device is moved back and forth over the surface to be wiped the blade is flexed back and forth at the hinge portion 7, there being also some slight play between holder and the sides 19 of the clamp. The head 6 is at all times maintained in contact with the face to be wiped and maintains uniform engagement therewith regardless of variations, in the surface or lack of careful fitting of the clamps, etc., so the wiping tends always to be uniform and even. Obviously no dirt, snow, or thelike can get in between the holder and the wiping blade, and the blade is firmly held in place in the holder. Should any water, dirt, snow or ice get in the space 7' adjacent the hinge, the head working back and forth during the flexing of the hinge portion causes the same to drop out and the device thus cleans itself. It will be noted that the shoulders formed at 55 form a stop for the head and these also at all times prevent the metal edge of the holder coming in contact with the glass or surface wiped. The device is inexpensive to manufacture and is applicable on practically any type of wiper or squeegee and has a comparatively long life in use.
