OBSERVATION-SHUTTER.

Be it known that I, jF ELD WHIrE, a citizen of the United States of America, residmg at Detroit, in the county of Wayne and State of Michigan, have invented certain .IIGW and useful Improvements in Observation-Shutters, of which the following is a specification, reference being had-therein to the accompanying drawings.

This vention relates to an observation shutterafor shielding 'an observer or operator using a view opening through armor, as 111 an armored car, an armored vessel,

fortifications or other likeplace, or operating field ordnance orfire arms in the open. The object ofthe invention is to shield such observer while at the Same time giving a' substantially unobstructed view through the opening'or to protect one-otherwise in the open, the device otherwise so arranged as to turnan ordinarylight projectile from elevation, partially broken away .and partially diagrammatic,.of an armored motor 'stru'ction may be made .without departing from the spirit of my invention and I do car equipped with observation shutters that embody the invention; Fig.2 is an enlarged- View in detail of an opening protected by such a shield; Fig. 3 is a view in rear elevation showing-a slight modification of the shield and its mounting, and Fig. 4 is a view in vertical section showing one method of l operating the shield when it is mounted so as to be shiftable, as indicated in- Fig. 3.

Referring to the drawing a circular disk 1 of suitable projectile turning armor plate, is provided with radial slots 2 and is mounted behind an o ning as indicated at Fig. 2 in such a way a sto be readily rotated at comparatively high speed.

Asshown in Figs. 3 and 4 one coniienient way of mounting the same is by securing.

' ing the shutter.

it on a-spindle/l that is journaled 1nj a rock arm ,5. A bracket 6 affords support for. the s motor. car, of armor thereon having obserinner'end of the rock arm, which swin on a suitable stud 7 Apertured ears 8 may bebrought-into alinement-with bracket lugs 9 whereby a pin 10 maybe thrust therethrough and hold the bracket in either rapidly rotating the'shutter.

sition desired. A pulley 1'1, gear wheelgor with any suitable sourceof power as by a belt 12 (see Fig. 1) or there maybe an electhe like on the spindle 4 may be connected tric motor directly connected to the shaft 4,

or any othersuitable means may be used to impart the necessary motion. V

'In'mounting such-a shield or shutter in an armored motor car, the powerplant of the car may be used to drive the'shuttcr. Bymountingthe same on a tiltable bracket or other like/means, the shutter may be moved away from in front of\the view opening at the V will of the operator. When the car is in ac-' tion, the rapidly moving shutter either in front of the driver orv those who are working the guns in the car, gives full protection to the latter, while the slots are passing rapidly enough. in" front of the eyes ofthe operator to afiord practically unobstructed view: Thus danger from projectiles is minimized and the operator is in comparative safety against small arm fire and shrapnel.v

It is apparent that such a shutter may. be

mounted atan advantageous point to protect one sighting a field piece in the open,

. or may be used to shield one firing a ride or other small ,piece, without regard to other armor or like shelter.

not care to limit. myself to any particular form or arrangement of parts. I

What I claim is 1. The combination with armor having an observation opening, of a circular observation shutter of armor material with radial slots therethrough rotatably mounted in register with the opening and means for 2. The combination with armor having an observation opening,-of anobservation shut ter, formed of a circular plate of armor material with slots theret-hrough, means rotatably mounting the shutter in register with the openings, and means for rapidly rotat- 3. The combination with an armored.

vation openings, rotatable observation shutto fr otate :theshutter disks at high speed,

' the slots being disposed to turn them-m to permit clear vision when the disks are rotating: a V- a v 4. A projectile turning observation shut- 5' ter having narrow observation openings therethrough and means for rapidly rotat- .ing the shutter. I

5. The'combination with armor having an observation opening, of a projectile turning '10 shutter plate, means for rotatably mounting the plate,v and means for rapidly rotating the plate,'the plate being provided withslots therethiough, means irotatably mount- 1 ing the shutter, and means for turning the shutter rapidly. I s v 7. An observation shntter cbnsisting of a rotatable armored plate with narrow slots therethrough and means for rapidly rotating the plate, the slots being so disposed in relation to the axis of motion of the plate as to prevent passage of shot and permit practically unobstructed vision therethrough when the plate rotates at high speed.

In testimony whereof I aflix my signature in presence of two witnesses.
