To all whom it may concern:

' face and 'head of welding operators and Be it known that I, WILLIAM L. GALLA- HAN, a citizen of the United States of America, and a resident of Garwood Union county, New Jersey, haveinventeol certain new and useful Improvements in Welding- Hoods, of which thefollowing isv a specification.

This invention relates to improvements in welding hoods. 7

The object of the invention is to provide a shield or hood for the protection of'the adapted to be quickly put on and adjusted for each individual operator.

Other objects of the invention are to pro vide a light, well ventilated shield or hood having protecting pads for the face of the." operator 'and so arranged that the protecting eyeglasses may be swung outward or otherwise temporarily removed from the window of the hood to permit the operator to inspect the work' with the naked eye and rest his eyes when the arc is not drawn without the necessity of removing the hood.

. Other objects will appear as this specification proceeds while reference is had to the accompanying drawing in which Figure 1 is a side elevation of a welding hood embodying my invention. Fig. 2 is a top view of the hood. Fig; 3 is a. horizontal sectional view through the window. Fig. 4

is a vertical central sectional view, and Fig.

The hood comprises the curved face shield 6 and the top or head shield 7 preferably made of sheet metal and suitably joined the operator slides the strapstogether unt the hood sits firmly on his head after which by a locking seam 8, Fig. 5. The top shield' is provided with a ventilating duct 9 .or.

there may be several such ventilating ducts. The hood is secured to the head of the operator by fastening

straps

10 and 11 which are slotted to permit ,of adjustment by a lock screw' orbolt 12. After the hood is put on he tightens the screw 12.

' For the protectionof the face and cooperating with the fastening straps there are provided two

face straps

and .both .are padded with a lining 16of 5'5 Theface straps also serve the purpose of preventing the cheek portions 17 spreading or gettingout of shape.

The operator obs'erves his work through a window o'penin 18 closed by a window containing colore glass to protect the eyes against the glare from the weldin arc. The construction contains some of t e features of the invention and is as follows: Surroundin the window opening 18 in the face shield t ereis a window casii1g'19, ,p referably an aluminum casting secured' to the shield by rivets 20 and provided .with hinge lugs 21, Fig. 2. The window comprises the from g in frame 22 which is also preferably made of aluminum for the sake of lightness and provided with hinge lugs 23 by means of which the window is hinged to the casing 19. 24;

are springs, one on each sideof the windowand'secured to the shield as shown for keepmg the window closed tightly against the j casing 19. The window is further provided .with a front flange 25 and from side to side of the window pass the rods 26 which serve two, purposes. First, they act as stops for the window against the casing.19 and second, they act asbacking for-the glass, see

Fig. 5.

cut away as at 29 to permit the glasses to be inserted from the one side.

30, 30 are-flat springs secured to the front .fiange 25. The glasses are inserted behind the springs which press the glasses against the aforesaid .rods 26 so thatthey are held securely within the frame 22.

The hood as here described and illustrated is very light, yet furnishes adequate protectric are causes additional air current so that the hood isv at all times well ventilated.

-During the work the -window may be tionfor the head of the operator. The duct 1 or ducts '9 provide'a means ofescape from the heated air aroundthe operators head within the hood and the heat from the elec 105 opened as shown in dotted lines in Fig. .1

to permit the operator to inspect the workF- and rest his eyes. The springs also serve to maintain the window in its open position as is evident from the drawing.

The details of construction may, be varied from that shown and described and I do not wish to be limited otherwisethan the scope of the appended claim requires.

I claim:

The combination with a Welding hood having an opening for observing the work,

a rectangular window casing secured to said hood and surrounding the said opening, a -W1I1Cl0W frame hlnged to the sald w ndow casing at the top thereof and provided with vertical front flanges on all sides thereof, lateral rods 1n said window frame adapted to abut the said casing when the window is closed, a plurality of difi'erently colored glasses adapted to be inserted through an opening in the one side of said window frameysprings interposed between the said front flan es and the said glasses at the top and the ottom thereof for keeping said glasses in position against the said lateral rods and a spring on each side of said window frame and secured to the said hood for normally keeping the said window closed.
