SHIELD FOR WELDERS HELMETS Filed April 27, 1945 Patented Feb. 5, 1946 UNITED STATES PATENT OFFICE SHIELD FOR WELDERS HELMETS Arthur Krogel, Spokane, Wash. Application April 27, 1945, Serial No. 590,547

3 Claims.

This invention relates to a shield for a welders helmet and it is one object of the invention to provide a shield which may be applied to the window of a helmet and serve very effectively to prevent rain striking the window of the helmet and blurring the Window so that the workman cannot see clearly through the glass of the window. As now made, the glass of a helmet is exposed to weather and when it is raining and water collects upon the glass it is necessary to remove the helmet and wipe the glass dry in order that a clear view may be had through the glass. This is very annoying to the welder and in addition causes loss of time.

Another object of the invention is to provide a shield having a portion adapted to rest upon the top of the window and provided with depending arms at its opposite sides so formed that they will firmly grip the window and hold the shield in place. Since the arms are of resilient metal the shield will be firmly held in place but may be easily removed when not in use or when it is desired to transfer it to another hood.

Another object of the invention is to provide a shield having side portions extending downwardly at an incline and serving to prevent rain from driving inwardly under the shield from a side and striking the glass of the window.

Another object of the invention is to so form n the rear portion of the shield that it will fit closely against the front of the hood over the window and very effectively prevent water from running down upon the glass of the window.

The invention is illustrated in the accompanying drawing wherein:

Figure 1 is a side view shield applied to a hood.

Figure 2 is a perspective view of the shield.

Figure 3 is a top plan View of the shield.

The improved shield is used as an attachment for a welders helmet and is applied to the window I of the helmet 2 which is of conventional formation. The window projects forwardly from the helmet and at its front end has the usual dark glass through which the workman may look at Work being done without his eyes being injured by looking at the flame through clear glass.

The shield 3 is formed of sheet metal or other suitable material and extends the full width of the window 3, side portions of the shield being bent downwardly to form diagonally extending side extensions l having depending flanges 5 along their lower edges. The side extensions and their flanges taper towards their front ends so that while their rear portions will serve very efshowing the improved fectively to prevent rain from driving under the shield and striking the glass of the window their forward portions will not block the Workmans view at sides of the window. It should also be noted that the lower edges of the flanges 5 extend horizontally level with the top of the window. A flat lip 6 extends rearwardly from the shield and this lip may have its rear edge 1 curved longitudinally so that it has close fitting engagement with the front of a helmet or the rear edge of the lip may be straight in order to fit closely against a helmet having a flat front. Resilient arms 8 hold the shield to the window and these arms are formed integral with the lip 6 and extend downwardly from opposite side edges thereof. Upper end portions of the arms are bent to form shoulders 9 for resting upon the top of the window and supporting the shield in the position shown in Figure 1 and lower ends ill of the arms are curved inwardly so that they will engage under the window and prevent the arms from slipping upwardly. Therefore the shield will be held firmly in place and since the shield and its lip are spaced upwardly from the top of the window the glass-carrying door at the front of the window may be swung upwardly without interference by the shield. Therefore the workman may move the black glass out of the way and he will be permitted to look at work done without removing the shield. The shield will be firmly held in place but may be easily removed when not needed or it is desired to transfer it from one helmet to another. When the shield is in place rain will be prevented from striking the glass of the window and blurring the glass so that the workman cannot see clearly through the glass. Therefore it is not necessary to remove a helmet and wipe rain water from the glass and this annoyance and loss of time is eliminated.

Having thus described the invention, what is claimed is:

1. A shield for a welders helmet comprising a visor of dimensions adapting it to extend the full width of the window of a helmet and project forwardly therefrom a distance suflicient to prevent rain water from striking the glass of the window, said visor having side portions bent to extend downwardly at an outward incline and formed with depending flanges along their lower edges, the saiddownwardly extending side portions and their flanges being tapered towards their front ends, a lip extending rearwardly from said visor for fitting in close contacting engagement with the front portion of a helmet above v the window thereof, and resilient arms at oppohaving their upper end portions bent to form' shoulders'for resting upon the top of the window and their lower ends bent to provide portions for engaging under the window. 7

2. Ashield for a welders helmet comprising a visor having downwardly extending side portions, a lip extending rearwardly from said visor for extending over the window of a helmet and abutting the front of the helmet, and resilient arms extending downwardly from op site sides of the lip for gripping a window from opposite sides, said arms having their upper portions bent to form shoulders for resting upon the Window spacing the lip upwardly and holding the lip in upwardly spaced relation thereto, andlower ends of the arms being bent inwardly for engaging under the window.

3. A rain shield fora welders helmet compris ing a visor of dimensions adapting it to extend the full width of thewindow of a helmet and project forwardly from the window an appreciable distance, a lip extending rearwardly from said visor for abutting engagement with a helmet over the window thereof, and resilient arms extending downwardly from opposite side edges of said lip for gripping the window from opposite sides, said arms having upper portions bent to form shoulders for resting upon thewindow'and from the window.
