UNITED STATES FRANZ LAIBACE, OF NEW YORK, N. Y.

LOCKOUT OR DOOR PEEP.

Application filed Kay 21, 1919. Serial No; 298,731.

To all whom it 121,04; concern:

Be it known that I, FRANZ LAIBACH, a citizen of the United States, residin at New York, county of New York, and tate of New York, have invented certain new and useful Improvements in Lookouts or Door Peeps, of which the following is a specification.

This invention relates to an improved lookout or door peep adapted to be applied to the doors of dwellings, lodge rooms, or the like to permit of visual examination by the occupants of any person desiring admission before the door is opened, the invention being an improvement on that disclosed and claimed in a previous patent granted to me on Dec. 10, 1918, under No. 1,287,349.

The present invention has for one object to improve the means for securing the door peep in place.

Another object is broadly to widen the range of vision of the door peep when applied to a. door of considerable thickness.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing 5, and to the appended claims in which too various novel features of the invention re more particularly set forth.

Figure 1 of the drawings is a front view of a door peep constructed according to my invention.

Figure 2 is an axial sectional view thereof. showing it in position on a door.

Figure 8 is a horizontal axial sectional view.

Figure 4 is a transverse section on the line 4-4 of Fig. 3.

Referring now to Figs. 1 to 4 1 indicates a door of ordinary construction such as 18 used in dwellings, lodge rooms or the like. This door is formed with an aperture 2 to receive the door peep which here comprises a tube 3 having soldered or otherwise secured on one end a sleeve-like extension 4 which fits snugly in the aperture 2.

The opposite end of the tube 3, which extends inwardly into the room or apartment, is formed with a cupped disc 6 whose flange projects over and localizes a ring 7 spaced between the disc and the inner face of the door, the purpose of this ring being presently set forth.

The extreme inner end of the tube 3 has soldered or otherwise fixed therein a flaring eye-piece 8 which carries a lens 9. A second lens 10 is carried at the opposite end of the door peep, being mounted in a short cylindrical member 11 which projects into the sleeve 4 at one end and at its opposite end into a cylindrical flange 12 projecting from a circular plate 13 upon the outer face of the door. This plate 13 may have soldered on its face a ring 14 holding a plain glass disc 15 which covers and protects the lens 10.

The lenses 9 and 10 are constructed in a manner known to those skilled in the art, to widen the range of vision from the eye piece so as to enable the occupant to obtain a comprehensive view through the door peep. In order to further increase the range of vision so as to enable a person out of direct alinement with the eye peep, or a number of persons, to be examined the lenses are secured in rings 16 mounted on vertical pivots 17 and are connected together by a telescopic strip made up of two parts 18, 18 and which is secured to one side of each of such lenses and extends through the tube 3 close to the side thereof, and may be extended or constructed according to the distance the lenses are spaced apart, the two parts of the strip engaging one another with sufficient frictional hold to move the shutters but may be moved upon one another by hand for adjustment.

Secured to one of the pivots 17 is a projecting handle 19 and it will be apparent that by manipulation of this handle the lenses may be swung on'their pivots to face at an angle toward either side of the door.

The device is held in position by means of screws 20 which pass freely through suitable openings in the disc 6 and door, and through tapped openings in the plate 13 and ring 14 and have nuts 21 threaded on their ends. The ring 7, before mentioned, acts as a spacer and rings of different axial width, or a plurality of rings, may be employed according to the thickness of the door in which the device is to be placed.

In front of the lens '9 I provide a air of shutters 23 and 24 which'are hinge on a common axis as at 25 on the disc 6 and have operating handles 23' and 24 thereon, the tube 3 being slotted to receive the shutters. The shutter 23 is solid-and the shutter 24 is provided with a slot 26 for a peep hole. The upward movement of both shuttors is limited by a lu 27 on the shutter 23 which engages the wa of tube 3 when the shutter is moved up. In order to hold the shutter 24 in position when the shutter 23 1s raised the handle 24' of the former has an integral spring clip or finger 24 WhlCh projects over and engages yieldingly a projection 24" on the disc 6. I

It will be understood of course that any of the shutter constructions here shown may be combined with any of the tube or mounting constructions and that plain lasses at both ends or a single lens at the inner end 7 are not only ada table for doors or the like,

but may be use for otherpurposes in the art demanding an oblique vision.

Having thus described my invention and set forth the manner of its use, what I claim as new and desire to secure by Letters Patent is:

1 A tube having angularly adjustable lenses therein, and means for supporting larly adjustable lens at each 0 positet end thereof, means for securing sai tube in a I door, and means for adjusting said lenses in unison.

3. In a look-out, an adjustable tube 'having angularly adjustable lenses, means for securin saidtube to a support and means for ad ustin said lenses 1n unison, said means inclu mg an extendible link passing through the tube and connected to the said lenses so that the lenses will co-operate through a limited angle of movement, or until the axis of each, fails to intersect the other.

4. In a look-out, a tube havin an angularly adjustable lens at each opposlte end thereof, means for securin said tube in a door, and means for adjustlng said lenses in unison, said means including a link passin through the tube atone side thereof, an connected at the opposite ends to the said lenses, so that the two lenses will co-operate through a limited angle of movement, or 7 until the axis of each fails to intersect the other.

In testimony whereof I have afiixed my signature.
