4"'Claims.' (Cl. 24--211) wThisinvention relates to mountings for welders"hel'- metsgface shields, and the like.

helmet to be readily'shifted'from aposition 'for'useto an out-of-use position and which vwill permit the "quick detachment and reattachment'of theface-shield or-helmet, if desired.

It .isia' further object of the present-invention toprm vide animproved mounting for welders"helmets,' face shields and the like which overcomes the diflicul'ties encountered with the devices heretofore available.

It lisa further object of the present-invention to provide' a mounting for welders helmets, face shields'and the; like which is simple yet sturdy inconstruction, and which ;can:be readily applied to helmets and-face shields now inuse.

'It-is' a further object of the present invention 1t01pr0- vide a mounting for'welders helmets, face *shieldsiand .the like, with which the interconnected parts can be readily detached and the operation of which "will 'be readily understood by the user.

Other. objects and advantageous featuresof'theinven tion willflbe apparent from the specification and claims.

The .na,ture. and characteristic features of the'invention. will :be more readily understood from the'following description, taken in connection with 'the accompanying drawings forming part thereof, in which:

Figure :1 is a .top plan view of asafetyhat and welding helmet with the mounting in accordance with the invention therebetween;

Fig.- 2 is a verticalsectional view taken approximately on t-he'line 2-2 of Fig. 1; and "showing-the helmetin its downward position for use;

Fig. 3 is a view similar to Fig; 22. but showing the helmet in its upward out-of-use posifliomc 'Fig; 4 is a fragmentary vertical sectional view taken approximately on the line 44 of Fig. 1;

Fig. 5 is a sectional view taken approximately on the line 55 of Fig. 4;

Fig. 6 is an exploded view in perspective of one portion of the mounting in accordance with the invention, parts being broken away to illustrate the internal construction; and

Fig. 7 is an exploded view in perspective of another portion of the mounting in accordance with the invention.

It should, of course, be understood that the descrip tionand'" drawings herein. are illustrative merely; and that various modifications and" changes can be-Jm'ade 1n the structure disclosed without departing from'the spirit of the invention.

Like numerals refer to like'parts throughout the several views;

Referring now more particularly to the drawings .a safety hat 10 of'wellknown' type is. illustrated, and is adapted "to: besupported and held upon "the head of the user inany desired'manner; The hat'lfl' can be.of vulcaniz'ed fibre oranyothersuitable material. and can have alongonev marginal edge portion. .thereof a visor .11 which is rearwardlydisposed'ffor one character. or

use of the invention and serves to protect the back' of the neck of the user. The hat "10 has downwardly extending substantially vertical side walls.12 with an.0utW,ardI y disposedrim -1'3 therebelow;

A welders helmet is shown at 15, is provided with the customary rectangular frame 16 for. the reception of a' lens .and'protective. cover glass (not shown) and has oppositely disposed side walls 17i The helmet'15 can be made of vulcanized fibre or, any othensu'it'able material.

The mounting 18, hereinafter more fully described,

employed to interconnect the hat .10 and the helmet .15

is shown in detail in'Fi'gs. 4, 5;. and 7'.

The side portions112" of"th'e.ihat 10', intermediate. the frontand the rear of theha't '10,,preferably1each-has securedthereto, by screws 20 extending therethrough, a

projectin'gtmounting ,block 21, which can b'e...cyli1idricia.l and circular in cross section, formingpartofIthemounh ing 18.

The mountingblocks 21 preferably, havetheirlinner faces 22 "inclined to conform-to the slope of I'theside portions 12" and are mounted so that-the longitudinal axes'of the nrountingblocks 21will be disposedin align.- ment. The blocks '21 can be madeof anydesir'edmaterial, resins of the phenol formaldehyde type .beingisuitable. 7

The mcuntingblocks '21each has .a transversebore 23 With'an' interiorshoulder 24 and an. extension 25. of reduced diameter, the opposite .end' 2'6'of.'lthe.bore;23 being threaded. v

A locking pin 27 is provided in .theflbore 23" andhas a shoulder 28 for. limiting the outward movement .of: the pin 27, as determined by the shoulder .24, andtoserve as an abutment for a. spring-29 whichlnormally urges it outwardly. The'spring29 'abuts,,at its. other end, against-a threaded plug 30. The plug30 .isin threaded engagement in the threadedend 26 r 'of .thebore .24.-

The locking pins 27 each has an end portion 31 .normally extending outwardly beyond the boreextension 25 and has apart 32 ofreduced-idiameter. adjacent its terminal or free end .for. purposes to. beexplained;

The-'sideportions 17 'of the shield 15-have-opp osed sockets 35 mounted thereon for thezreception of the mounting blocks 21. The sockets 35 arecomplemental in shapeto the mounting blocks 21, inthesidewallportions'thereof have lockingslotslwithiinnericircular portions" 3610f a: diameter correspondinguto. thatot; the end portion 3101? the pin, and slots 37 extendifig to the outer edges of the sockets 35 of a width corresponding to the diameter of the pin part 32.

The pins 27 normally have end portions 31 engaged in the slot portions 36 to hold the sockets 35 in position on the mounting blocks 21. Separation of the sockets 35 from the mounting blocks 21 can be effected by pressing the pins 27 inwardly, against the force of the springs 29, to bring the parts 32 to a position at the slots 37 thereby to permit the axial separation of the sockets 35 from the mounting blocks 21.

The sockets 35 can be mounted on the interior of the side walls 17 of the shield 15 in substantial axial alignment in any desired manner but it is preferred to provide an adjustable connection, on each side of the shield 15,

head 41 is adapted to engage with a friction washer 44 which inturn engages with the inner face of a flange 45 at the inner end of the socket 35. A friction washer 46 is provided in engagement with the outer face of the flange 45 and with the inner face of the side wall 17. The noncircular shank 42 is preferably in engagement with a complemental opening 47 in the side wall -17 to prevent the turning of the stud 40.

On the stud 40, and in contact with the outer face of the sidewall 17, a metallic washer 48 is provided for engagement by a spring washer 49. The threaded end 43 extends through the washers 48 and 49 for engagement by an adjusting nut 50. By turning of the nut 50, the frictional drag imposed upon the turning of the supports for the sockets 35 and accordingly the freedom of movement of the face shield, can be varied to suit the desires of the user.

It will be seen that with the sockets 35 in locked engagement on the mounting block 21, the helmet 15 can be raised or lowered as desired, and by reason of the adjustable frictional drag imposed upon the sockets 35 the desired degree of tightness and frictional holding can be quickly attained by adjustment of the nuts 50.

If, at any time, it is desired to separate the helmet 15 from the hat 10, for use of the hat alone, or for any other purpose, this can be readily effected by pressing the pins 27 inwardly to their releasing positions and separating the sockets 35 from the mounting blocks 21. The resilient character of the hehnet is such that no ,difliculty is encountered in separating the wall portions 17 to the required extent. The helmet 15 can be quickly reattached to the hat 10 by a reverse of the operations required for separation.
