' To all whom it may concern:

Be it known that we, Trmonoan Soni- DORSKY and JACOB Baaasrrrcn, citizens of the United States, residing, respectively, at New York city, in the county of Bronx and State of New York,.and at New Yer city,

in the county of New York and Eitate of New York, have invented certain new and useful Improvements in Door Attachments,

of which the following is a full, clear, and

exact specification.

This invention relates to door attachments, particularly devices whereby a person seeking admittance may be viewed from within without opening the door.

One object of the present invention is to provide a device of'this character which may be attached to a door of substantially any thickness found in practice.

Another object is to provide means for attaching the device from within,so that the same may notbc tampered with by any on authorized person without.

more fully up ear from the detailed description and the eatures of novelty will be particularly pointed out in the claim.

In the drawing illustrating this invention, Figure 1 is an elevation of our improved dcvice viewed from the exterior of the door, a

fragment only of the latte" being shown.

Fig. 2 is an elevation of the device, viewedfroin the interior of the door. Fig 3 is an elevation corresponding to that in Fig. -2, with the small door or wicket open. Fig. 4: is a section partly broken away to illustrate the interior construction. Fig. 5 is a sectional view illustrating a' modified form containing a spring catch for holding the removable window. Fig. 6 is a further modifled form in which .the wicket is mounted to swing upon a horizontal instead of a vertical axis. Fig. I is a detailvie'fw illustrating the fram'e with the adjustablestraps.

The device comprises essentially a frame passing through an aperture in a door from the exterior thereof, this frame being provided with adjustable straps extending through the door and fastened at the interior thereof; a removable w'n scoping within the frameprov means for holding the same in. adios. position; and a small door or wicket which mag be opened from within.

starring in detail to the drawings, the frame consists preferably of an annular late 10, having a tubular extension 11 prw ecting therefrom and entering the apex-'- ture from the exterior or the door. tending from this tubular portion ll straps 12 formed of sheet metal or some other easily beat material. The ends of these straps may be bent over at the interior and fastened to the interior of the door by suitable attaching means such as screws 13, passing through perforations 14 formed adjaccnt the ends of the straps. As the latter 1 may be readily bent, it will be seen that they y can be made to tit any thickness of door. 76 A suitable frame may also be provided at the interior of thedoor, this frame havin a tubular extension 16 fitting the interior 0 the aperture and disposed in substantial alineinentwith the tubular portion 11 ofthe exterior frame. The frame 15 may be 215 toned by suitable fastening means such as screws 17, passing into the panel of the door. A door or wicket 18 is hinged to the frame 15 and suitably latched thereto by a latch 19.

The aperture is normally closed at the oxterior the cot by a window 20 mounted within a frame consisting of a tube 2], telescoping within the tubes 11 and 16, and provided with an inwardly extending unnular rim 12 against which the window abuts, the latter being held firmly in place b a split collar 23 which is suitably fastens to the interior of this tube. The latter abuts against an inwardly extending annular 95 shoulder or rim 25, forming an ei'rtension of the plate 10, past the tubular portion 11. The tube may be clamped in position by suitable means such as a set screw 26 threaded in boss '27. formed at the interior 100 of the tube. Thus when the person within desires to observe the person seeking admittance, he opens the wicket 18, and if he is still not satisfied, he may unclamp the tube 21 by unscrewing the set screw and 105 remove the same, so as to leave the aperture free for communication. Then the tube 21 may be replaced and the wicket closed, restoring the device to normal position.
