HAND SHIELD Non nLncrnIc WELDING.

Application mea March 14s, 1925. Serial No. 16,486.

My invention relates to an improvement in'handv shields .for electric welding.

An object is to provide a portables-hield that can bie easily vheld in the right position I V5 and moved intodiiferent positionst will to suit the comfort and convenience of the user.

The invention is made of suitable non lnflammable or insulating ymaterial of a gen- 10 eral pyramidalform, with an opening at the center flanked inside and out with a metal framing and adapted to receive removablyl a colored glass.

It further consists Ain features that -will' be. included in the general description and set forth in the claims.

In the accompanying drawings: Fig. 1-is a view in perspective;

'Fig' 2 is aside viewg,

Fig. 3 is an-enlarged vertical section; Fig. 4 is a horizontal section; and Figs. 5 and 6 are details.

The shield is preferably made of a single piece -1 of non-infiammable, non-conducting material, such, for example, as fibre, bent at the lfour cornersl 2 vand fashioned into pyramidal formv with the edges 3 brought together and fastened by rivets 4 or in any other-approved manner. An opening -5 is 80 formed atthe center, and this is covered over by glasses 6, preferably colored. The opening is flanked y aframework 7 preferablyof sheet-metal on the outside, and

this is held by rivets or other means 8. A l sheet-metal frame 9 inside forms a recepso that it is bowed inwardly, conforming to position for the work he is doing, and in the follower from sliding out of place. The horizontal edges 15 of the frame 9 are curved inwardly. The follower is suiiciently long the Acurvature and bearing at the center against the glasses as shown in Fig. 4, whereby to hold. the latter removably in place, but with suiicient firmness and rigidity to keep it tight.

A, handle 16 is held in the socket 17 4by a screw or rivet or equivalent means 18. lThis handle isp-referably square to prevent turning in operators hand. The operator grasps in one hand and holds the shield before his eyes, while manipulating the welding electrode 19 with the other hand, as illustrated in Fig..1. In thisway, he 'is always able to move it into the desired this way he can move it closer or further fromhis face and eyes or twist it or otherwise adjust it to.- suit-the requirements.

- An article of this character is, light, durable, portable,.and in many instances is far better adapted for the work than the helmet used for this purpose.

I'claim: 1

1. A lens holder including a frame, a lens mounted in said frame, a springv follower carried by the frame for holding the len-s in proper position therein, and laterally bent spring prongs extending outwardly from said follower and normally' engaging the lens to hold said lens firmly in position.

2. A lens holder including a frame having the rear edges thereof curved in a substantially concave form, a lens mounted in the frame, and a spring follower carried by the supporting frame and conforming to. the curved rear edges thereof for holding-the lens in position, said spring follower having laterally bent spring prongs extending outwardly therefrom and normally engaging the lens to hold the same firmly in position. 90

In testimony whereof I aiiix my signature.

FREDERICK M. BOWERS.
