LENS-HOLDING DEVICE FOR FACE SHIELDS.

Application filed May 17, 1920.- Serial No. 382,059.

To 'aZZ whom it may concern.

Be it known that I, GUsT A. PETERSON, a

citizen of the United States, residing at Chicage, Cook County, Illinois. have mvented certain new and useful Improvements in Lens-HoldingDevices for Face Shields, of which the following, taken in connection with the drawings, is a description.

My invention relatesto face shields or protectors designed to be used inshielding the eyes of workmen who are occupied on work such as welding or the like, where the eyes of the workmen have to be protected from extreme heat and light as well as flying particles.

It is also an object of my invention to provide means for holding the glass or lens or other transparent means in proper position with respect to the frame; also to provide a frame of this kind by means of which the transparent member may be easily and quickly changed when it becomes necessary or desirable; also to provide an ad justable mechanism whereby one or more glasses or lenses may be held in position in said shield.

A further object of my invention is to pro vide means within the rim or frame of the glass holder for insuring pressure against the glass or lens in the frame, whereby it may be retained in position while the device is in'use, and enable the user to quickly and easily remove and replace the same without an tools or other contrivance for so doing.

in the accompanying drawings I have illustrated what I now consider the preferred form of an embodiment of my invention, without desiring to be limited as to size, contour or material out of which the shield is made.

In these drawings Fig. 1 is a front elevation of the shield,

Fig. 2 is an enlarged detail of the window of the shield in front elevation;

Fig. 3 is a sectional detail on line 33 of l igure 2,

Fig. 4 is a sectional detail on line 44: of Figure 2. 7

Referring to the drawings A represents the body of the shield which may be constructed of fiber, metal or any other opaque material which is not easily affected by heat, and is formed of a size suitable to cover the face of the user when held in front thereof. At the top edge of the shield, the body portion is formed into a concave or dish shaped ed e by cutting the material and over-lapping the edges of the out portion as shown at a-a and securing the overlapped edges together by rivets a or otherwise At the lower end of the shield I provide a handle B which may be either of the same material or of any other material suitable therefor and attached to the shield body A.

In the upper part of this shield is provided a fenestral or sight openim C out through the body portion A, preferably rectangular, although it may be of any other shape desired. Fitting into this opening is a metal frame D angular in cross section, shown more clearly in Figures 3 and i. The inner sides of this frame D are bent to form a groove d within which the edges 0 of the fiber body surrounding the opening C is received, and by pressure applied thereto this frame is clamped to the body A and held in position by frictional contact therewith.

The uppe edges of the frame D are bent to form flanges or shouuders, Zal and eX- tend the entire length of the sight opening C. The sides or ends of the frame D are bent to form a groove 6 at each end of the frame, which grooves open toward each other,the bent portion of the frame forming an abutment for the ends of the glass E.

rt will be observed that the shoulders (Z extend outwardly beyond the glass E, which provides for more than one glass or lens being placed therein, and also provides a deflector for sparks from the fire.

F is a leaf spring, there being one at each end of the window which is disposed within the groove 0 as shown more clearly in Figure 1-. Each of these springs bears directly upon the end of the glass E, holding it close- 1y to the frame and preventing its displacement.

One end 7 of this spring is bent, folded and clamped between the frame D in the body portion A, which holds it firmly in position, the bend in the frame forming the grooved preventing the springs from moving sidewise in one direction, and the bend in the frame forming the groove 6 preventing any sidewise movement of said springs in an opposite direction.

The upper end. of the groove 0 is open to permit the insertion of the glass E in position, the spring F assuming the position shown in Figure 4, the glass being slipped into place in the frame and under the pres: sure of the springs F held in position until broken or removed for any other purpose.

To remove the glass it is only necessary to press against the glass at the upper edge thereof from the inside of the shield and remove it from the frame.

It will be observed that the glass, or lensholding frame is constructed from a single piece of metal bent to form a double set of grooves at each end thereof, by means of which the frame is secured to the body. of the shield, and also receives and retains the glass and the spring for holding the glass 1n position, said spring being retained in position by clamping between the frame and the shield body.

If more than one glass is desired, or if a glass and other transparent material of con trasting colors are desired to be used, they are placed in position and held under the springs F in the manner heretofore de scribed for the one glass.

I claim:

1. A device of the class described comprising a shield having a body portion of opaque material having an elongated window open ing therein, said body portion being slit and overlapped on the edge thereof, a mm attached to the shield within said opening for supporting a transparent member therein, a

leaf spring positioned between the rim and transparent member at each end thereof to maintain it in position.

2. A device of the class described comprising a concave shield having an opening therethrough, a lens-holding rim formed of a single piece of material having means in the edges thereof for fixedly attaching said rim to the shield through said opening and attaching it to the shield body, a transparent member held withingrooves formed in said rim, leaf springs between said rim and the shield body. and adapted to bear against opposite ends of the transparent member.

3. A deviceofthe class described, comprising a concave shield having a handle attached at the lower end thereof, said shield having an elongated opening out there through, a lens-holdingv rim formed of a single piece of material,the end portions of said rim being bent to form oppositely facing grooves, leaf springs between said end portions of the rim andthe shield body, viewing members positioned within said rim and held in position by the tension of the aforesaid springs. r r

4:. A face shield having aconcave body portion provided with an opening therethrough, a lens-holding rim having engaging members formed integrally therewith to fixedly secure it through said'opening to the shield body, shoulders formed in said rim, the ends of said rim beingbentto form grooves, a transparent memb-e positioned between said shoulders and extending into the aforesaid grooves, and springs bearing against theends of said transparent members to maintain them in place, and a handle attached to the lower edge of said shield.

In testimony whereof I have. signed this specification.

eUs'r A. PETERSON.
