Application October 1,

' 9 5 Kiwi a voluntary matter or made compulsory by state Jew, Obviously the purpose of these safety hats is to protect the head of the wearer from injury which might be caused as an incident to his workin's.

While as a general rule it is necessary that all of the woren on any particular-job wear these safety hots, those on the job who are engaged in arc welding operations must weer a welding helmet or shield to protect them from the dying particles of steel and oxide which are thrown out by the welding operation.

At the present time it is en impractical proposi= tion, it not an entirely impossible one, for the operator to at the same time wear a safety hat end a welding helmet, as the presence of the safety hat on the wearer's head precludes the possibility of the welding helmets of known design being positioned thereover.

Accordingly, this invention has in view as its foremost objective the provision of a safety hat and welding helmet which may be worn at the some time on the heed of the wearer. In carrying out this objective in e, prscticol embodiment, the invention takes cognlnsnce of the feet that for long perlods of time the seiety hat will be worn alone, end the invention, therefore, has in view as a further more detailed objective the pro vision of a combination safety-hat and welding helmet which are readily detached and assembled so that one or both may worn, as occasion demsnds.

Due to the need for efiectively guarding the head end face of the -weeiiei' against flyi icles of steel and oxide, the invention has in view as a further more detailed objective the provision of means for creating a seal between the helmet and safety hot,

Ordinarily a certain amount of space between these two articles is required so as to permit of swinging movement oi the helmet with respect to in accordance with this invention a. protective strip is interposed between the helmet and hat along a required line to prevent flying particles of therebeyond.

I 55 Jinview of the fact that many conditionsarisepsssese of fillin oxide and steel passing 1937, Serial no. 166.800

in which the weldingoperotor will be desirous of wearing the welding helmet or shield alone and dispense with the safety hat, the invention also has in view as an important objective the provision of a. welding helmet of the character above described which may be readily attached to and detached from either one of these safety grate or a. headgear mode clone conventional ines.

It is now common practice in the art of welding helmets to employ a, headgear which consists substtially of a headband that extends about the he of the wearer, and which headband is provlded with a cross strip that extends across the top of the wearer's he. In accordance with this invention, this headgear is manufactured as a single unit, and is provided with means for attsching a, welding helmet thereto in such a manher thatit may be readily detached therefrom.. Thus the welding helmet may be applied either to one of these headgears or to a safety hot, as occeslon demands.

Various other more detailed objects and advantages such as those which arise in connection with the carrying out of the above noted objectives will in part become opponent and in part he hereinafter stated, as the description of the inventionproceeds.

The invention, therefore, comprises an combination welding helmet and satiety hot, and in which the welding helmet is readily attached to or deinched from a hot when the letter is in position on a wearers heed. Associated withthe helmet and hot are means for guarding against the particles of steel and oxide therebetween. An essential part of the inven tion also lies in the combination of the welding helmet with e, headgear made along conventional lines, which is adapted to have the welding helmet attached to or detached therefrom.

For a full and more complete understanding of the invention reference may he had to the following description and accompanying drawings, wherein Figure l is a side view developing a safety hat in the position in which it will be worn on a wearers head. In this view the upper part of e. welding helmet is also brought in to bring out the relationship of the welding helmet to thesafety hat,

Figure 2 is a sectional showingtsken at right angles to the showing of Figurel, and in this by the line 2-2 of Figure l, I

Figure 3 is an enlarged detailed view in perspective of one of the extensions on the welding helmet which connect the latter either to the hat or headgear,

Figure 4 is a view somewhat similar to Figure 1, developing the welding helmet substantially in its entirety by bringing out the relationship of this helmet to a headgear to which it may be attached; part of the helmet being broken away to develop the construction of the headgear,

Figure 5 is a sectional showing normal to the showing of Figure 4 and taken about on the plane represented by the line 5-5 of Figure 4,

Figure 6 is an enlarged detailed view in section of one modification of the shell which maybe employed betweenthe helmet and hat, and

Figure '7 is a similar view ofstill another modification.

Referring now to the drawings, wherein like reference characters denote corresponding parts. a safety hat is shown in Figures 1 and 2 and referred to in its entirety by the reference character H. Safety hats of this type are well-known and are available to the public as such. Ordinarily they include an outer shell it which may be made from a canvas base Bakelite oran appropriate vulcanized fibre. This outer shell is hard and rigid, and is intended to provide the required protective effects.

This shell lli assumes the dome-like shape illustrated in the drawings, and along its free lower edge is formed with an outwardly extending flange designated I l. The dimensions and curvature of this flange ll may vary at diflerent points about the hat, but "along each side assume the dimensions and curvature particularly illustrated in Figure 2. I

The outer shell III is supported from an inner harness l2 which is designed to snugly fit the head of the wearer, the outer shell It being maintained in spaced relationship from the harness. This harness l2 may be made from fabric or strips of vulcanized fibre. Ordinarily it includes the headband shown at l3, and strips which extend upwardly therefrom and towards the top;

of the wearers head; these being designated l4.

An anchoring band 9 may be secured about the inner side of the edge of the shell III as by rivets 8, and interposed between this band 9 and the shell iii are the extremities of the strips l4. At

' their upper ends these strips [4 may cross or be connected together by the cord band 9 is formed with upwardly extending ears 6 from which are struck tabs 5 that, at their lower ends, are secured to the headband l3 as by the rivets 4. Thus the shell 10 is supported in spaced relationto the headband l3.

At each side the outer shell [0 of the hat H is provided with a pair of spaced shoulder rivets it. These rivets l5 have heads and spaced from the puter surface of the shell ll, providing shoulders designated IT, for a purp se to be hereinafter pointed out. The upper part of a welding helmet is shown in Figure 1 as comprising a mask member M having the usual curvature by which it is adapted to fit about the wearer's face and protective eflects. This mask M is provided with the usual filter glass at It.

The maskM is'pivotally mounted at each side to a pair of extensions designated l9 and Isa respectively. The pivotal mountings at each side of the mask M are referred to generally by the refshown at I. The- IS that are enlarged provide the desired s,'1e'/,eea

This view is taken about on the plane represented erence character 24, and the detailed construction .ofthese pivotal mountings need not be described here in detail. It suiiieq to say that the mountings are eiiective to provide a required amount of frictional resistance to pivotal move-- ment of themaskMwith respect tothe extensions it and its whereby the mask will remain in any position into which it may be adjusted. A friction device for this purpose is clearly illustrated and described in the co-pending application ofFrederick M. Bowers, Serial No. 166,187, flied Oct. 1, 1937, and entitled Headgear friction joint device for welding shiel The extensions l2 and Ila are of duplicate const'ruction, and only one of them needs be described for thepurpose of this specification. At the lower extremity the extension II is of the loop formation represented at 2|, and which loop formation receives the pivotal mounting 22. As shown in Figure 2, this loop formation 21 snugly fits in the curvature of the flange I I.

Above the loop formation the two thicknesses of the material defining the extension it are "joined together, and for all elective purposes constitute a single unitary strip, this strip being provided with elongated openings 22 that are enlarged. as shown at 23. These openings 22 are spaced apart a distance corresponding to the spacings of the rivets I! on the hat 3.-

At this point it is well to note that the mask 11 and extensions l2 and [to may be made from any appropriate material, but a vulcanized fibre has now-assumed a definite status in the art of welding helmets and is indicated as a preferred material, as it is particularly adapted to the manufacturing operations. v

The enlarged portions 22 of the elongated openings 22 are designed to have the heads it of the rivets it pass therethrough. Thus the extensions i2 and Isa may be detachably anchored in position on thehat H by causing the enlarged head it to pass in the enlargements 23 of the openings 22, after which lateral movement is imparted to the extensions i2 and "a to cause the rivets I! to move upwardly in the elongated openings 22 whereby I engage the extensions I2 and lie to securely hold them in position onthe outer shell ll of the hat H. With the extensions I2 and its thus positioned the mask M is pivotaily mounted on the hat H. Y

In order to effectively E -Id against fly D"- ticles of metal and oxide when the mask M is in eflective position, the invention has in view the use of interlocking angle irons which amended by the shield and hat respectively, to provide a seal in the space between these parts. As shown in Figure 1, the mask M carries a strip of angle iron 24 that may be anchored thereto in any appropriate manner, as by the rivets shown at 2!. A second angle strip that is complemental to the strip 24 is shown at 26 as being carried by the shell it of the hat H and secured thereto by rivets 21. when the mask M is in position in front of the wearer's face these angle strips 24 and 2" will interlock in the manner illustrated, and provide an effective seal. i

In some instances the interlocking arrangement shown in Figure 1 may be dispensed with and a single strip that is carried either by the shield or hat employed. For instance, as shown in Figure 6 the strip 24 that is carried by the mask M substantially fills the space between this mask M and the shell It, to provide the desired protective effects, or asshown in Figure 'l the strip 2! the shoulders II of the rivetsare-7,900

that is carried by the shell II will alone provide the protective effects.

Referring now more particularly to Figures 4 and 5, a headgear which isma'de along conventional lines is shown as comprising a headband 28 that is adapted to extend about the head of a wearer, and which carries the cross piece 20 that fits over the top of the head of a wearer. The

headband

28 and 29 ismade' from the usual fibrous material, and is comparable to the conventional headbands now incorporated in the welding helmets and shie -maskMareadaptedtobe headband adapted mit passage of 'through.

At each side thecross piece 29 carries a pair of spaced rivets which are in all respects similar to the shoulder rivets ii that are carried by the hat I-I. Thus the extensions l9 and Na of the anchored to the headgear in the same manner as they are secured to the hat H.

While preferred specific embodiments of the invention are hereinbefore set forth it is to be clearly understood that I am not to be limited to the exact constructions illustrated and described,

because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims.
