Application January 6, 1938, Serial No. 183,640

'1 Claim.

Our invention relates'to the class of devices which are employed by workers to protect their eyes and faces from the injurious effects of extremely bright light, sparks, etc. incurred in autogenous welding and similar operations, and an object of the invention, among others, is theprovision of a hoodor mask to protect the face combined with shields for the eyes, which mask shall be particularly efllcie'nt to accomplish the purposes for which it is intended.

ne form of a mask embodying our invention, and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawing in which- Figure 1 is a side view bf the head of an individual shown as wearing ,our improved device to protect the head and face.

' Figure 2 is a similar view, butwith the 'mask in a raised position and the goggles or glasses in place to shield the eyes.

Figure 3 is another similar view but showing both the mask and the goggles or glasses in raised positions. Figure 4 is a top view of the device, but showing only fragments of the mask.

Figure 5 is an isometric perspective view on enlarged scale of portions of the device illustrating the connections for the parts.

In operations involving autogenous welding and similar occupations it is at times important to protect the face and eyes, at times protection of the eyes only being required and at other times it being essential that the entire face be protected. As these operations of shielding the eyes or face, or uncovering the latter, occur frequently and at short intervals and for comparatively brief periods, and as one hand of .the operator is generally occu'pied in holding a torch or other implement, it becomes essential that means be provided. whereby the hood orgoggles employed for shielding the face and head may be conveniently-and quickly operated with one hand and often in' quick succession. The device forming the subject matter of this application is designed to satisfy all of these requirements with minimum inconvenience to the wearer, such device as illustrated in the drawing herein comprising 'a head band 6 of any suitable material made to fit the upper part of the head and passing around it at the forehead. A supporting bands! secured at its opposite ends to the head band passes over the top of the head as shown in Figs. 2 and '23 of the drawing. In the preto the head band, mask supports 8 are employed, the inner ends of which project through said bands and may be riveted or otherwise secured in place. The mask 9 is pivotally attached at the outer ends of the mask supports, as shown in Figure 5, so that said mask may be swung into position to protect the face, as shown in Fig. 1, or may be supported in a raised position as shown in Figs. 2 and 3, the pivotal connection being tight enough to-support the maskin either of the pogitio shown, and for'this purpose screws in threaded into the supports may be employed. A pair of goggles II are adjustably supported by the band 6 in such manner that they may be moved to and from the band to fit faces of dinerent shapes as to the position ofthe eyes and as to'the depth of the face from front to back. In

'latter each being pivotally attached at one end to the band 6, each member of each pair of links being pivotally attached to a member of the -op-, posite pair, and as shown in Fig; 5 ofthe drawing. In order that suflicient friction may be had to hold a joint from. free swinging movement the pivots are provided with screws by means of which the proper friction may be obtained. It is preferred that the pivotal attachments for the goggles and those for the mask itself shall be separately formed, the goggles being attached to the band 6 in front of the pivotal attachment for the mask, but this arrangement may be departed from if desired. It will be observed that, as herelnbefore described, either the goggles or the mask may alone be'placed in front oithe face to shield the latter or the eyes, and either or both may be swung to .a position over the head when not required, and

and quickly moved from one to the other of the positions.

In accordance with the provisions of the patent statutes we have described the principles of operation of our invention, together with the device which we now consider to represent the best embodiment thereof; butwe desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out. 1

We claim:

A head protector'including a support to be -by a. horizontal pivot whereby the 808G188 may 10 be swung upwardly and downwardly relative to the longitudinal axis of the link member to which they are attached, said goggles when in eye protecting position presenting one of the link members below and substantially parallel with said support whereby the protecting positions of the goggles to fit diflerent faces is changed by movements of the goggles horizontally of the head.
