JOHN 5. N01? TON. BY

ATTORNEYS.

Patented Apr. 19, 1932 UNITED STATES JI'OHNQ. NORTON, 011 SAN FRANCISCO, GAIJIORNIL wnnnnws noon Application filed October 11, 1930. Serial 110. 488,128.

My invention relates to improvements welders hoods, audit consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a welders hood in which an eye shield section is movable in the plane of the front face of the hood by a chin-actuated means for un covering the eye opening in the front face.

The glare shield is held in raised position by means of a weighted trigger, and the operator can free the trigger from the shleld by moving his head abruptly in a lateral direction, whereupon the shield will drop mto closed position by gravity.

A further object of my invention is to provide a device of the type described which is simple in construction and which dlsposes the dark glass on the inside of the hood and the protecting glass on the outside of the hood.

Other objects and advantages will appear as the specification proceeds, and the novel features of the device will be particularly pointed out in the claims hereto annexed.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a section along the line 1-1 of Figure 2, 0

Figure 2 is a front elevation of the devlce, and

Figure 3 is a rear elevation.

Tn carrying out my invention 1 make use of a standard hood indicated generally at 1 and having a front .face 2. The hood is supported upon the head of the operator by a headpiece 3.. The parts thus far described are standard in construction and form no part of my invention except insofar as they cooperate with the partsnowto be described.

The front face 2 has an opening 4 which is disposed at the level of the operators eyes.

A glare shield indicated generally at 5 is slidable across the opening 4 and isconstructed in the following manner.

An outer member 6 is slidable on the outer face of the portion 2 of the hood, and this member has flanged edges 7 for reinforcing it. y The side flanges 7 slidably engage with guides 8 that are secured to the face 2. The

bottom flange 7 rests against a stop 9 which is also secured to the face 2.

The piece 6 is secured to a U-shaped member 10 that is disposed on the inner face of the part 2.and is spaced from the piece 6 by a U-shaped spacing member 11. The outer sides of the member 11 bear againstthe sides of the opening 4 and guide the glare shield 5 in its movement. y

The glare shield carries glasses which cover an opening 12 in the piece 6. A dark glass 13 is disposed on the inside of the glare shield and is secured to the U-shaped member 10 by side clips 14 (see Figure 3) and a bottom clip 15. A clear protecting glass 16 (see F igure 2) is disposed on the outside of the glare shield 5 and is secured to the piece 6 by side clips 17 and a bottom clip 18. These glasses are removable so that new ones can be sublowermost position with the exception of the opening 12, and this opening is covered by the

glasses

13 and 16. V The means for raising the glare shield 5 vertically is shown in Figures 1 and 3. 19 are pivoted to the U-shaped member 10 and are disposed beyond the sides of the glass 13 so as not to interfere with the vision. These arms are connected to levers 20 that are pivoted at 21 to a support 22, the latter being secured to the inner face of the part 2. Links 23 are secured to the inner ends of the levers 20 and have their other ends secured to an enlarged end 24 of a pull rod 25. The rod 25 is guided in a sleeve 26 that is carried by the support 22. p

An adjustable chin rest 27 is carried by the along a rack 28 formed in the rod 25.

I also provide means for supporting the .glare shield 5 in raised position, and this comprises a weighted trigger. 29 (see Figure '3) pivoted at 30 and having a cam edge 31 and a top edge 32. A pin 33 is carried by the glare shield 5, and the upward movement of the shield will cause the pin 33 to engage with the cam edge 31 and swing the trigger 29 in a clockwise direction about its pivot 30. The

triggerwill swing back into the position shown in Figure 3 when the pin 33 clears the edge 31. A freeing of the glare shield 6 w' now cause it to move downwardly until the pin 33 rests upon the top edge 32. The trigger 29 will now support the glare shield in raised position. 4

From the foregoin description'of the various parts of the dev1ce, the operation thereof may be readily understood.

i 10 The hood ad usted on the operators head in the usual manner, and the chin rest 27 is raised so as to lightly contact withthe chain of the operator. Theweight of the glare shield 5 will hold it in closed position,

16 and the operators eyes will be protected by the

lasses

13 and 16.

Vhen the operator wishes to raise the glare shield, he moves the chin rest 27 downwardly, and this, through themechanism already de- 20 scribed, raises the glare shield and uncovers the lower part of the opening 4, The operator can now check the work. The trigger 29 supports the glare shield in raised position as long as the operator desires.

. In-releasing the glare shield, the operator moves his head abruptly in a lateral direction, which causes the weighted trigger 29 to move in a clockwise direction about the pivot 30 and to free the pin 33. The glare shield 30 5 will now drop into closed position by avity.

4 Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of 3 various changes, and I reserve the right to employ such changes as may come within the scope of the claims hereto annexed.

I claim: 1. The combination with a welders hood 4 having a front face with an opening for the eyes therein, of a glare shield normally covering the opening, chin actuated means for sliding the shield along the hood surface into open position and comprising arms pivoted to the sides of the shield, levers connected to the arms, links connected to the levers, and a bar connected to the links and having a chin support extending beneath the chin.

2. The combination with a welders hood having a front face with a sight opening therein, of a glare shield normally covering the opening, means for moving the shield in the plane of the front face of the hood for uncovering the opening, a member engage- 5 able with the shield for holding thelatter in open position and being releasable from engagement when the hood is moved abruptly in a lateral direction.
