.SPYING APERTURE FOR DOORS, WALLS, AND THE Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed August 6. 1907. Serial No- 387.353

To all whom it may concern:

Be it known that I, JOHN SHAoKLEY, subject of King of Great Britain, residing at Whitehaven; in the county of Cumberland, England, have invented certain new and useful Im rovements in S ying A ertures for Doors,%Valls, and the Li e, of w ich the following is a specification.

This invention contemplates certain new and useful improvements in spying apertures or devices for doors, walls or the like, so that, for instance, a householder may see the person at the door Without such person seeing the one inside, before opening the door, so as to determine whether or not the door shall be opened.

The invention consists essentially of a pair of devices designed to be fitted within openings in a door, wall or the like, said devices being provided with glass or lenses through one of which the person inside may view the person outside without himself becoming seen, and at the other of which there is desi ned to-be placed a light of any character W ich will shed its rays through the latter device upon the person outside so that such person ma be seen at night.

With this and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arran ements and combinations of the parts that T shall hereinafter fully describe and then point out the novel features in the ap ended claims.

For a and the merits thereof and also to acquire a knowledge of the details of construction and the means for effectin the result, reference is to be had to the folfbwing description and accompanying drawings, in which:

Figure 1 is a perspective view illustrating the applicatign of my invention to a door.

Fig. 2 1s a transverse sectional view of a door equipped with the invention. Figs. 3 and 4 are similar views of modifications hereinafter specifically referred .to.

Corresponding and like arts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters.

Referring to the drawin the numeral 1 designates a door, which I ave selected for the purpose of illustration, although it is to be understood that my invention 18 e ually applicable to walls and the like. The door 1 is provided with two openings 1 and 1", that 11 understanding of the invention and which is normally closed by an opaque shutter or disk 5 which may be swung or otherwise moved away from the opening and which in the present instance is shown as pivoted at 6.

The illuminating aperture or device comprises a front plate 7 which. may be similar to the front late 2 and which is preferably countersunr in the door at the front of the opening 1". A lens 8 is held in the opening by the front plate. 9 designates the back plate of this opening. A reflector 10 is set ack of the opening 1 and is preferably provided on its lower side with a segmental rim 11 formed with an arm 12 by which the reflector may be secured to the door.

13 designates a smoke guard which in the present instance is in the form of an angular plate, one member of which may be slipped back of the ed e of the back plate 9 so as to frictionally'hold the smoke guard in proper position to protect the woodwork from the illuminant held between the reflector 10 and the opening 1".

From the foregoing description in connection with the accompanying drawing, it is obvious that a person may hold a light of any character in front of the reflector and thereby throw the rays upon a person standing outside of the door, wall or the like, while. at the same time the-person inside may view the 'person outside by merely moving the shutter 5 away from the opening 1. Obviously the erson outside cannot view the person inside during this operation. By this means it will be seen that I have provided an efficient device which, as an examle, will be a large measure of protection to liouseholders, as they can scrutinize visitors before opening the door, and thus protect themselves against possible insult and inury, or annoyance.

The spying device, as well as the illuminating device, may be made in diversified ways, and the parts variously arranged.

For instance, as illustrated in Fig. 2, a ring 14 may be provided to receive the glass or lens, said ring being provided with an inturned flange 15 extending around the glass or lens and with an outturned flange 16 which may be secured to the front plate 2 by means of the curled over edge 17 of the latter. Asillustrated in this view, an outer tube 1.8 is fastened to the ring 14 and is provided with interior threads designed to engage the exterior threads of the tube 19 which fits snugly in the opening 1 and which is secured to and forms part of the back plate 4.

Fig. 3 illustrates a modification in which 20 designates the front plate. This front plate is provided with bosses 21 in which tie rods 22 screw, said tie rods also extending through the back plate 23. T he front plate 20 is provided with a shoulder 20 against which the glass or lens 24 abuts, the said glass or lens being held in place by a ring 25 screwing in the front plate from the rear.

Fig. 4 illustrates another modification in which the front plate 26 is provided with a rearwardly extending flange 27 within which the glass or lens 28 is mounted, 29 designating a ring screwed into the flange 27 to se cure the lens or glass in place: The flange 27 is exteriorly threaded also and is engaged by the interiorly threaded tube 30 formed integral with or secured to the back plate 31. In this form, in order to prevent the front plate from turning while the back plate is being connected thereto, the said front plate is provided with a pin 32 embedded in the door or like structure to which the device is applied. It is obvious that the front and back plates maybe of such size as to support both the spying device and illuminating device,

and that the illuminating device may be placed either above or to one side of the spying device, as judgment may dictate. When the illuminating device is placed to one side of and on a line with the spying device, the former should be so adjusted that the rim of the reflector will protect the light from the eyes of the person spying out, and the smoke cap should be tilted or moved to proper position to protect the door.

The interior of the spying device should preferably be painted or otherwise made solid black, as well as the front side of the shutter, so that'the person outside-may not see the movement of the shutter to the open position, and the reflector should, of course, be kept bright.

Having thus described the invention, what is claimed as new is:

1. The combination with a door, wall, or the like, provided with two openings extending therethrough, of a glass held in one of said openings, a removable closure secured to the door or the like at the rear side of said opening, a lens held in the other opening, and a reflector secured to the door or the like at the back of said last named opening and spaced therefrom, said reflector being formed at its lower side with a segmental rim.

2. The combination with a door, wall, or the like, provided with twoopenings eX- tending therethrough, of a glass held in one of said openings, a removable closure for the rear side of said opening, a lens held in the other opening, areflector at the'rear side of the last named opening and spaced therefrom, said reflector being formed at its lower side with a'segmental rim, said rim being formed with a downwardly projecting arm secured to the door or the like, a back plate secured to the door at the rear of the last named opening, and an angular plate, one' part of which is adapted to be slipped back of the edge of said back plate into frictional engagement with the same and the rear face of the door, over the reflector.

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

JOHN SHACKLEY.
