Patented Jan. 5, 1932 UNITED, STATES PATENT OFFICE' JOHN S. NORTON, 0F SAN FRANCISCO, CALIFORNIA, ASSIGNOR 0F ONE-THIRD TO 'WIL- LIAM F. HOLLINGSWORTH, OF SAN FRANCISCO, CALIFORNIA WELDEBS HOOD Application med August 18, 1930. Serial No. 476,188.
The present invention relates to improvements in a welders hood, and its principal object is to provide 'a convenient means or operating the lens of the hood so that the Welder when desiring to view the Work ma raise the lens without the use of his han and without changing his position.
More particularly it is proposed in the present invention to use a pressure means or operating the lens and to arrange the pressure means in such a manner that the same may be actuated by a bulb arranged to lie in the arm p-it of a person wearing the hood so that the lens may be raised by squeezin the upper arm against the body.
It is further proposed in the present invention to use a hood made of leather or fabric or flexible -composition and to arrange the operating means in such a manner as to allow of free access of air into the hood and to give as much comfort to the operator as 1s possible.
Further objects and advantages of my invention will appear as the specification proceeds.
The preferred form of my invention is illustrated in the accompanying drawings, in which Figure 1 shows my hood on a Welder;
Figure 2 shows a rear view of the fro-nt section of the hood including the principal parts of my operating mechanism;
Figure 3 a vertical section taken along line 3-3 of Figure 2, and
Figure 4 a horizontal section taken along line 4-4 of Figure 2.
While I have shown only the preferred form of my invention, I .wish'to have it understood that various changes or modifications may be made within the sco e of the claims hereto attached without eparting from the spirit of the invention.
In its preferred form my hood indicated at 1 is preferably made of leather or flexible composition of suitable kind, and has a frame 2 made of metal provided in the front portion thereof. yThis frame for which a suitable openin is made in the hood material is fastene to the marginal portion of the latter by an inner frame 3, the margin of The frame itself has mounted over its vopening a hinge 5 to which is pivoted the lens frame 6. The lens frame carries an inner lens 7 of eye protecting properties, held in place by means of springs 8 and an outer lens 9 of ordinary glass held in place by two guide members 10 and bottom members 11.
One of the edges of the lens has an arm 12 extending rearwardly therefrom, and the outerend of this arm is connected by means of a link 13 to a piston Irod 14 extending from a piston 15, which latter is reciprocable in a cylinder 16 mounted adjacent the lens opening. The piston rod passes through a Vguide plate 17, and a spring 18 surrounding the piston rod and bearing on the guide plate has a tendency to push the piston upward in the cylinder. The upper end of the cylinder has a s ort pipe 19 extending therefrom, and this ipe connects with a flexible tube 20, having a ulb 21 at its outer end so that by compression of the bulb air is forced into the cylinder, and urges 'the piston 15 outward, whereby through the action of the link 13 and the arm 12, the lens is thrown upward into the dotted line position shown in Fi re 3. The tube 20 is preferably made su 'ciently long that it can be guided around the back of a person as shown in Figure 1, and allow the bulb 21 to be held in one of the'arm pits, and to be compressed by a slight movement of the upper arm. y For the convenience of the operator a spring clamp 22 may be fastened to the bulb whereby the latter may be secured to the upper arm of the individual using the devlce.
Above the lens, I preferably fasten a spacing member 23 consisting of a fairly wide strip of spring metal having a central por,- tion 24 corresponding to the outline of the meansof which it may .be fastened to the top of the frame. `A suitable elastic 26 fastened to the two ends of the member 24 may be guided around the head for holding the metal 'human forehead, and having two legs 25 by portion of the hood in position relative to the forehead.
The advantages of my invention will be readily understood from the foregoing description. The hood made of exible material maybe more easily carried and accommodated in smaller space than the hood made of rigid material. It is particularly adapted for overhead work and for work in tight places. The operating means for the lens is particularly effective and easily operated. The bulb being fastened to the upper arm, does not interfere with any of the other operations of the Welder, and whenever it becomes necessary for the latter to raise the lens so as to have an opportunity to inspect the work, he need only press his forearm against his body, which will cause the lens to swing upward on the hinge 5. If he swings the lens far enough the arm 12 and the link 13 become practically aligned for holding the lens in wide open position. Under normal conditions the spring 18 automatically returns the lens, and the other movable parts into proper position as soon as the pressure is relieved.
I claim:
l. A welders hood of the character described having a movable lens, pressure operT ated means for actuating the same, a bulb and a flexible tube connecting the bulb and the said means, the exible tube being suiciently long to allow the bulb to be positioned in the arm pit of a person wearing the hood and to be compressed by a movement of the Welders arm, and means for fastening the bulb in place.
2. A Welders hood of the character described having a movable lens, pressure actu- .ated means for actuating the lens, a bulb having a limb encircling member secured thereto adapted to embrace a limb of the Welder and allowing the bulb to be compresse-d by a movement of the limb, and a flexible tube connecting the bulb with the pressure actu'- JOHN S.
