ATTORNEY Patented Oct. 8, 1935 UNITED STATES PATENT OFFICE 30mins.

This invention relates to improvements in. welders helmets and more particularly to the head mountings thereof.

Among the objects of the invention are to pro-' vide an adequate shield for the face of the operator that is light in weight, comfortable, easily put on and taken off and that will protect the welders cars from flying metal.

Other objects and advantages will appear as the description progresses.

In this specification and the accompanying drawings, the invention is disclosed in its preferred form. It is to be understood, however,

that it is not limited to this form because it may be embodied in other forms within the spirit of the invention as defined in the claims following the description.

Autogenous welding and cutting of metals is fraught with vocational hazards to the welder, principal among which are blinding light rays given off by the welding flame or are and the incidental heat, in addition to the fusing metal, flying particles of which constantly bombard the person of the welder.

Hampered as he is by uncomfortable working conditions, often exposed to the inclemencies of the weather, a welders helmet must combine efficiency with comfort and yet be strong enough to withstand rough usage.

In the two sheets of drawings:

Fig. 1 is a vertical section of a welders helmet constructed in accordance with this invention in position on a welders head as indicated in dot and dash lines.

Fig. 2 is a rear view looking into the helmet,

the pivotal structure on one side being shown in vertical section.

In detail the construction illustrated .in the drawings, referring to Fig. 1, comprises the head piece composed of the overhead strap l andthe brow band 2 fastened at their intersecting points by the

pivotal rivets

3 and 4 on opposite sides of the head respectively. The rearward extensions of the brow band are joined by the elastic strip 5 to form a yielding band horizontally encircling the head.

The triangular earguards 6 and I engage the

pivots

3 and 4 and are further attached to the head assembly by the

rivets

8 and 9 respectively which pass through the ear guards and the head strap and brow band to hold these parts against The visor III is preferably composed of a single sheet of hard pressed fiber board. This sheet is laterally slit on opposite sides of the center portion as at ll-ll', l2l2', l3l3'.' The margins adjacent these slits are overlapped and riveted l.

as at M to form a hollow masklike shell extending back to'about the ears at the sides l5l5'; and overhanging the forehead at the top l6; and extending under the chin at l1. These riveted overlapping margins greatly stiffen and re- 10 inforce the structure enabling the use of relatively light gage material.

It is advisable to overlap the parts with the lower edges outside as shown in Fig. 2. This pre vents the delemrious rays of light radiating up- 15 ward through these seams.

The

pivots

3 and 4 pass through the sides Iii-I5 so that the visor l0 may swing freely thereon even to the extent of being swung over the head without removal. I v

The adjustable chin rest consists of the strap i8, pivotally fixed to the opposite sides I5--l5' by bolts and nuts as at 19 and 20. This band rests against the chin and the comfortable adjustment can be fixed by tightening up the bolts and nuts 25 so that the helmet will always fit its individual wearer. The holes 2|, 22, 23 provide adjustments for different facial contours to bring the window 24 into proper relation to the line of vision and the welding area.

This window has the frame 25 within which the window is hung on the spring hinge 26 so that the window can be swung outwardand upward'to remove the ray filter glass from the line of vision for unobstructed examination of the 35 work between welding operations.

Autogenous welders are constantly being sprayed with molten metal. They often work overhead while lying down in which position the molten metal rebounding from the floor will se- 40 verely burn their ears outside and in. An instance is recorded where an ear drum was pierced by hot metal. In this flank attack the ordinary helmet is no protection to the ears. 45

The ear guards 6 and 1 are held tightly against the ears of the welder by the tension of the elastic strip 5 to eifectually close the ears and guard them against the hazards mentioned.

Having thus described this invention, what is 50 claimed and desirer to secure by Letters Patent is:

l. A .welders helmet having a head piece; a visor pivoted to said head piece and ear guards fixed to the inner sides of said head piece and visor.

2. A welders helmet having a head piece including a head strap; a brow band having an elastic insert and fixed to said head strap; ear guards attached to the inner sides oi. said brow 5 band; and a visor pivoted to said head piece.

3. A welders helmet including a head strap,

a brow band and a pair of ear guards fixed together; opposed pivots extending through said strap, band and guards; and a visor pivotal on said pivots and spaced outward tromsaid ear guards.
