This invention relates to new and useful improvements in a safety head gear.
The invention has for an object the construcvtion of an article as mentioned which is capable 5 of protecting the head of a person and adapted to be used in Wars, riots, and other disturbances. More specifically, the invention contemplates l characterizing the safety head gear with a steel skull cap having an opening for the face, and closing said opening with a bullet proof vision glass plate.
It is a further object of this invention to provide an arrangement which permits the glass plate to be removed and replaced in the event of breakage. 1.5 Thus, more than one glass may be carried by each person.
' Still further the invention proposes to provide a reinforcing bridge across the top portion of the skull cap to make it stii, rigid and strong. Another one of the objects of -this invention is -to provide layers of asbestos or other insulating material and strong lining within the skull cap to protect the head. v Another object is to arrange the head gear so that the air supply to a wearer is not hampered, and thereis no cramped condition to irritate ones feelings during wearing periods. g
Still further the invention also proposes an arrangement which will permit the glass plate to be lifted and maintain a slightly raised position to permit fresh air to be readilydrawn into the skull cap. It is contemplated that a person may so wear the safety head gear, when there is'no immediate danger. l
For further comprehension of the invention, and of the objects and advantages thereof, reference willbe had to the following description and accompanying drawing, and to the appended 40 claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawing forming a material part of this diselosure:-'

FigA isafront viewsimilarto Fig. 1 butillustratinga modiiication. Y
Fig.- 5 is a fragmentary enlarged sectional view takenontheline5-5ofFig.4.
The safety head gear, according to this invention,v comprises a steel skull cap Il having an 5s opening I I for onels face. An exchangeable bullet lproof vision glass plate l2 is provided for normally closing said opening.
The skull cap I0 is formed with a reinforcing bridge ,I3 extending across the top thereof from slightly above the brow to the back of the head.- 5 Within the skull cap at the back of the head there are several layers of material I4. These layers preferably comprise layers of asbestos and strong ,lining'material and are for the purpose of protecting onels head from excessive heat when it l0- is required of the wearer to pass through hot zones and re zones.
i A leather strap l5 is attached along the bottom edge of the skull cap at the sides and the back and has strap portions |59- adapted to engage beneath 15 the wearers neck. A buckle I6 is associated with thel strap portions I5@ holding the strap portions together in various adjusted positions and so provide for attaching the head gear upon diierent persons. Air may enter the head gear at the front near the chin of a wearer.
Along the edge of the opening Il there is a U- shaped track element l 8. This track` element has an open top side. 'I'he glass plate I2 is slid in from the top. It is maintained in position by 25 several pin bolts I9. Each of the pin bolts I9 comprises a screw or bolt portion I9a which is mounted upon the material of the skull cap and which supports a washer portion I9b engaging over the top edge of the glass plate. When desired, the washer portion I9b `may bepivoted to the position indicated by the dot and dash lines in Fig. 3 and this Will`take the pressure off the bolt portion ISR which then may be removed to permit removal of the glass plate The track I8 is 35 provided with a soft protective pad |89- which engages against the edges of the glass plate l2 to protect the edges from undue shock and breakage.
. In Figs. 4 and 5 a modied form of the'invention has been disclosed which distinguishes from 40 vthe prior form'in several respects. According to this form there are adjustable pin bolts 29 adapted to .hold the glass plate l2 downwards, completely within' the track as indicated bythe dot and dash lines |22, or in a raised position. A 45 spring 3l)v is mounted on the bottom portion of the V,track and normally urges the glass plate I2 intoithe raised position.
E/ach pin bolt 29 -comprises a wing head clamp screw 3l upon which a cam element 32 is mount- 50 ed. This cam element engages against the edge 0I the plate l2. When the cam element is in the position shown by the full lines on the drawing the glass plate I2 will bevraisedby the spring 30. Then there is a small opening 33 betvrfeen the 55 bottom edge of theglass plate and the opening I I in thefskull cap through which air may be readily drawn and through which the user may easilyl converse. When an emergency arises it is merely necessary for the wearer to loosen the wing screws 3l, turn the cams 32 into downward extending positions, and then tum in the wing screws to hold the cams in these positions.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself tothe precise constructions herein disclosed and the right is reserved to all changes and modications coming within the scope of the invention as defined in the appended claims.
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent isz- 1. A safety'head gear comprising a steel skuil cap having an opening for the face, a U-shaped track extended along the sides and the bottom of said opening, an exchangeable bulletproof vision glass plate mounted on said track for closing said opening, and said pin bolts for holding said glass plate uponsaid track, each pin bolt having a wing screw portion supporting a cam portion which may be turned upwards or downwards, and resilient means urging said glass plate upwards against the cam portion.
2. A safety head gear comprising a steel skull cap having an' opening for the face, a U-shaped track extended along the sides vand the bottom of said opening, an exchangeable bullet proof vision glass plate mounted on saidtrack for closing said opening, and said pin bolts for holding vsaid glass plate upon said track, each pin bolt having a wing screw portion supporting'a cam portion which may be turned upwards or downwards, and resilient means urging said glass plate upwards against the cam portion', said resilient means comprising a spring mountedupon said track and engaging the edge ofsaid glass plate.
3. A safety head gear, comprising a steel skull cap having an opening for the face; a U-shaped track extended along the) sides and the bottom of said opening, an exchangeable bullet proof glass plate mounted on said track for closing said opening, elements mounted along the open side of said track and being adapted to engage the top edge of said glass plate for releasably holding said glass plate in position on said track, and resilient means mounted on the lower vportion of said track and operating between said track and the lower edge of said glass plate to force said glass plate against said elements in the released position thereof to form a slight opening at the bottom edge of said glass plate through
