Application July 1, 1954, Serial No. 440,750

1 Claim. (Cl. 2--8) This invention relates to a combined welders hood and safety hat, the primary object of the invention being to provide a welders hood including a safety hat constructed of suitable rigid material, such as metal, plastic, fiber or laminated fabric or the like, which will offer resistance to objects which may fall on the heads of welders while at work.

An important object of the invention is to provide yieldable means connected between the hood or mask and supporting hat, to cushion the sudden jar or shock directed towards the head by falling objects striking the hard hat.

Still another object of the invention is to provide means for removably connecting the helmet to the supporting hat, to the end that repairs or adjustments of the hat or hood may be readily made and the hard hat may be worn on the head without the welding hood.

A further object of the invention is to provide a connecting means between the hood or mask and the cap, which will permit the hood or mask to be swung from a vertical operative position to a horizontal position above the face of the wearer, eliminating the necessity of removing the hood to expose the face of the Welder wearing the hood.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of the hood harness which supports the hood and hat.

Referring to the drawing:

Figure 1 is a transverse sectional view through a welders hood, constructed in accordance with the invention.

Figure 2 is an enlarged fragmental sectional view illustrating the means of connection between the hard hat and hood head harness.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.

Fig. 4 is an elevational view illustrating the type of fastener used between the hard hat and hood head harness.

Fig. 5 is a side elevational view illustrating the hood as positioned on the head of the user.

Referring to the drawing in detail, the hood comprises a hard hat section 5, which is constructed of rigid mate rial such as plastic fiber, laminated fabric, metal or the like, molded or otherwise shaped to conform to the general shape of the head.

This hat section 5 is provided with socket members or keepers 6 into which the heads 7 of the head and socket fasteners extend.

The heads 7 are carried by the free ends of the spring arms 8, that are riveted at 9, to the strap 10 of the hood harness which supports the hood and hat on the head of the user.

A strap 10 is designed to fit over the top of the head of the person wearing the hood and has its ends con 2,753,562 Patented July 10, 1956 nected to the head encircling strap 11 at 12. Secured to the inner surface of the hat section 5, and disposed centrally of the hat section, is a liner 13 which is constructed preferably of sponge rubber, the liner being curved to fit the inner surface of the hat section 5, with its lower curved edge spaced a substantial distance from the strap 10, as clearly shown by Fig. 2 of the drawing, to allow the hat section to move vertically with respect to the strap 10 and head of the person wearing the helmet. Openings 13 are formed in the liner 13 through which said spring arms 8 extend when secured to the hard hat section.

The reference character 14 indicates the head-engaging web which encircles the lower ends of the strap 10, as better shown by Fig. 1 of the drawing, the web or strap 14 being supported by means of the lacing cords 15, so that the web may be adjusted to properly fit the head of the wearer, by tightening or loosening these cords.

Secured to the head encircling strap or web 11, and extending from opposite sides thereof, are the rods 16, which rods have their outer ends secured to the blocks 17 that in turn are secured in openings of the mask 18, the springs 16 providing means for normally holding the mask 18 in proper spaced relation with respect to the hard hat or outer shell section of the hood. These rods also permit of rotation of the mask 18 from a vertical position, as shown by Fig. 5 of the drawing, to a horizontal position above the head of the wearer, so that the face of the wearer may be exposed without the necessity of removing the hood.

The mask is provided with the usual Window 19 through which the welder or person using the hood may view his work, while welding.

Forming a part of the hard hat section 5, is an extension 20 which provides a protecting member for protecting the back of the head and neck of the wearer against falling objects.

From the foregoing it will be seen that the head of the wearer of the hood and hard hat, forming the subject matter of the present invention, will be protected against injury by the hard hat section, and the sudden jar and shock directed to the hard hat by falling objects, will be absorbed by the spring arms 8 and sponge rubber liner 13, the spring arms 8 acting to return the hard top hat to its normal position.

Having thus described the invention, what is claimed is:

A welders helmet comprising a hard hat section, a hat harness embodying lengths of web material adapted to closely fit over the head of the wearer of said helmet, a liner constructed of sponge rubber material secured to the lower surface of said hard hat section, spring arms connected with hood harness at one of their respective ends, said hard hat section having keeper openings, headed fasteners extending into said keeper openings, secured to the other ends of said spring arms removably connecting said spring arms to said hard hat section, and a protecting mask pivotally connected with said harness for swinging movement over the hard hat section.
