(Grant ed rt e-ta of" March s, 1883, amended April 30, 1928;"370"0.-G.@157)" The invention described herein may be: manu factured and used 'by' or :for. the Government for governmental ipurposes, without the payment to. me of any royalty thereon.- I i This invention relates. to a. shieldefor observation openings: a I 3 Where occupants of'a chamber'or'compartment are SUbjECtltO :gun -fire orgas attacksit is customary to provide slits; or openingswhereby they may observe with minimum exposure. the case of armored vehicles and tanks it has; been found that a large number of eye injuries occur due to the splash of the metal of the bullet.
The principal object of the invention is to provide a novel shield which includes a transparent portion and an armoring and sealing portion. These portions are mounted so that they may be readily moved into line with the sight opening in a wall member.
To these and other ends, the invention consists in the construction, arrangement and combination of elements described hereinafter and pointed out in the claims forming a part of this specification.
A practical embodiment of the invention is illustrated in the accompanying drawings, wherein:
Fig. 1 is a perspective view of the improved shield and its mounting.
Fig. 2 is a view in front elevation with parts broken away.
Fig. 3 is a view in side elevation of the entire unit.
Fig. 4 is a longitudinal sectional view on the line 44 of Fig. 2 and showing the transparent portion in line with the sight opening.
Figs. 5 and 6 are similar views showing other positions of adjustment of the auxiliary frame, and
Fig. 7 is a perspective view of the movable auxiliary frame.
Referring to the drawings by characters of reference, there is shown a support 5 which is the wall of a chamber or compartment. The wall is provided with a sight opening which in the preferred form consists of a relatively wide slot 6. A portion 6a of the slot is generally perpendicular a distance view while a portion 61) is inclined to afford a close View; The outer side. of the support adjoining the slot is provided with inclined surfaces 5a to protectthe sight opening against the splash from bullet.
A main frame '7 extending about three sides of the slot 6 is attached to the support by means of bolts 8. A head rest 9 of a resilient material is held onto the upper part of the main frame 'by means of clips 10 secured by screws 11 to the sides of the main frame. The main frame-7 cooperates with thesupportin formingwa socket in which an auxiliary frame 12- (Fig. 7) may be inserted. o
Theauxiliary frame 12 is formed of a thin flexible metal and includesv a top :13, sides; ;14141 that are offset inwardlyas at. 15 intermediate their. height, and an arched or bowed bottom 16 constituting a handle. Stirrups 1'7,-17 are provided' on the, lower ends. of; the sides Mi.
A relatively thick metal guard plate 18- :is-carried in the upper part of the auxiliary frame, being supported on the offsets 15. On one side of the guard plate there is a gasket or rubber pad 19 which is preferably vulcanized to a thin plate 20 that is attached to the guard plate by means of screws 21. The pad 19 is of sufficient dimensions so that it may be used to close the sight opening 6 (Fig. 6).
A laminated glass plate 22 is carried in the lower part of the auxiliary frame, being supported on the stirrups 17. The plate 22 may be readily inserted and removed from the auxiliary frame by exerting pressure on the handle 16 to cause the sides 14 of the frame to spread apart as indicated in dotted lines in Fig. 7.
In the position of adjustment shown in Fig. 4 the auxiliary frame is inserted all the way into the main frame so that the glass plate 22 is positioned opposite the sight opening 6 and an observer may look through the sight opening. In this position the auxiliary frame is held by means of a pair of plungers 2323 mounted in the opposite sides of the main frame and'engaging in apertures 2424 in opposite sides of the upper part of the auxiliary frame.
When it is desired to secure protection against the entry of bullets the auxiliary frame is grasped by its handle 16 and pulled downwardly until the apertures 24-24 are engaged by a second set of plungers 25-25 mounted in the main frame below the plungers 23. In this position of adjustment (Fig. 5) the guard plate 18 is in line with and covers the sight opening.
When it is desired to prevent the entry of gas through the sight opening, the auxiliary frame is removed from the main frame, reversed, and then reinserted until engaged by the lower set of plungers 25 to position the rubber pad 19 over the sight opening as shown in Fig. 6.
It will be noted that the glass plate 22 is of a thickness equalling the combined thickness of the guard plate 18 and pad 19 so that the auxiliary frame may be moved upwardly from either of the positions of adjustment of Figs. 5 and 6.
I claim:
1. In a shield, a support having a sight opening, a main frame secured to the support and extending on opposite sides of the sight opening, an auxiliary frame of flexible metal movable in and out of the main frame, said auxiliary frame including a top, sides with inwardly directed olfsets intermediate their height and with stirrups on the lower ends, and an arched bottom constituting a handle, a guard plate in the upper part of the auxiliary frame and supported on the offsets of the sides, a pad on one side of the guard plate, a transparent plate in the lower part of the auxiliary frame and supported on the stirrups, and plungers carried by the main frame and adapted to selectively engage the auxiliary frame in positions with the guard plate and transparent plate in line with the sight opening.
"2. In a' shield, a support having a sight opening, a main frame secured to the support and extending on opposite sides of the sight opening, an auxiliary frame of flexible metal movable in and out of the main frame, said auxiliary frame including a top, sides with inwardly directed offsets intermediate their height and with stirrups onthe lower ends, and an arched bottom constituting a handle, a guard plate in the upper part of the auxiliary frame and supported on the offsets of the sides, a transparent plate in the lower part of the auxiliary frame and supported on the stirrups, and plungers carried by the main frame and adapted to selectively engage the auxiliary frame in positions with the guard plate and transparent plate in line with the sight opening.v v
3. In a shield, a support having a sight opening, a main frame secured to the support and extending on opposite sides of the sight opening, an auxiliary frame of flexible metal movable in and out of the main frame, said auxiliary frame including a top, sides with inwardly directed offsets intermediate their height and with stirrups on the lower ends, and an arched bottom constituting a handle, a guard plate in the upper part of the auxiliary frame and supported on the offsets of the sides, a transparent plate in the lower part of the auxiliary frame and supported on the stirrups, and means for supporting the auxiliary frame in positions with the guard plate and transparent plate in line with the sight opening.
4. In a shield, a support having a sight opening, a mainframe secured to the support, an auxiliary frame movable in and out of the main frame, a guard plate in the upper part of the auxiliary frame, a pad on one side of the guard plate, a transparent plate in the lower part of the auxiliary frame, and means for supporting the auxiliary frame in positions with the guard plate and transparent plate in line with the sight opening.
