J A DOOR ATTACHMENT.

Specification of Letters Patent. Patented Feb. 22 1921 Application filed May 17, 1919. Serial No. 297,922.

To all whom it may concern:

Be it known that I, URBAN F. DURNER, a citizen of the United States,residing.at Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented certain new and useful Improvements in Door Attachments, of which the'following is a description.

My invention belongs to that general class of devices known as doors, and relates more particularly to an attachment for use on doors, whereby one at one side of a closed door can observe and converse with one at the other side of the door without first requiring the opening of the door. The invention has among its objects the production of a device of the kind described that is simple,.convenient, durable, ornamental efficient and satisfactory for use wherever found applicable. It has especially as an object the production of a device which.

when applied to a door will afford security and safety, as well as being convenient and preventing annoyance. Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the description here after given. To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and de scribed, and more particularly pointed out in the claims. p

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a perspective view of a of a door equipped with .my device; Fig. 2 is a view in elevation of a of the door and my device;

Fig. 3 is a sectional vlew taken substantially on line 33 of Fig. 2;

4 is a sectional view taken substantially on line 4-41: of Fig. 2;

Fig. 5 is'a sectional view'taken substantially on line 55 of Fig. 4;;

Fig. 6 is a sectional view taken substantially on line 6-6 ofFig. 2;

Fig. 7 is a sectional view similar to Fig. 4: illustrating a slightly modified form of device; I V

Fig. 8 is a view illustrating a modified form of plate and sleeve; and

Fig. 9 is a sectional view illustrating a modified form of hinge construction.

" Referring to the drawings, 1 represents portion portion 7 any type of door, whether in dwelling, apartment, office, hotel, institution, or the like,

and regardless of whether an outer door or an innerdoo'r. I have not considered it necessary to 1llustrate the details of the door construction proper, as this varies in differ,- ent types of doors, and depends upon the use to-which the door is tobe put as well as the materials out of which it is made. It is sufficient, however, to say that my device is applicable for any door regardless of the use'to whichit is to be put orits construction.

The device in its broadest sense consists of an attachment which may be applied to the door, the door being providedwith a small opening of the preferred size and shape at a desired point. When my device is closed, all the privacy and security of the usual door is obtained, but observation may be made and conversationcarried on to the satisfaction of the one at the inner side of the door with perfect security and as conveniently as if the door had been opened. The preferred construction consists of an inner frame or the like arranged at the inner side of the door, the same carrying a closing member or what may be'termed a small sight door of opaque material, which may be opened to permit observation and 'conversation. I also employ a slide or second door member arranged to permit observation, and which may be raised to facilitate conversation, or the passing of a card, telegram, receipt or money or the like through to the one on the inner side or vice versa. Referring to the drawings, 2-3 represent a frame which may be constructed as desired, as shown, in two parts or plates, the same being secured inplace by screws 4 or their equivalents for the purpose. The plates may be cast, stamped, cut, or otherwise constructed.

One of the plates, as shown,'3 is provided with an opening 5 of the desired size and shape, which may benormally closed by the sight door'member 6, whichis arranged to completely close the opening.

In the construction shown, the si ht door 6' is formed with extending parts i which serve as hinge members and extend into the grooves 7 (see Fig. 6), these being normally maintained-in place by the resilient straps 8 or their equivalents, which also act to shut and maintain the sight door 6 closed. The other plate or frame part 2 is preferably cut out at 9.as indicated in Fig. 5,3 but provided with extending parts or stops 10. Ar-

ranged in the frame part or plate 2 is a slide frame 11, which ispreferably provided with a transparent pane or panel 12 of glass or equivalent material, which may if desired be secured in place by the member 13 or. its equivalent for the purpose. The slide frame part ll is provided with the extending lugs ,14 arranged to engage with the stops 10 and vided with a pin 16, which may be split at the end as shown, and is of alength to extend into the opening 17 in the slide 11. As shown, the pin 16 is carried by a part 18 secured to the door, and extends through the frame part 3 see Fig. 4), 19 being a knob for opening the door and at the same time withdrawing the locking pin 16, so that the slide 11 may be raised if desired. The pin 16 thus locks slide 11 closed, and as a result the inner door 6cannot bemanipulated and opened from the exterior side of the door 1. At the outer side of the door I provide a plate or frame part 20, which may be secured in place by screws 21 or their equivalent for the purpose. Formed separately or integrally with one of the plates, as shown, integrally with plate 20, is a sleeve part 22 of a size to fit the opening out in the door. thereby improving the appearance of the device as well as making the opening the exact size desired. I have shown a sleeve part 22, which may be employed instead of extending part 22 entirely through the opening. The sleeve part 22" may be the desired size for the particular door, but if too large may be out down to fit or adjusted.

I have shown a plate 2, the purpose of which is to'prevent the sliding frame 11 from marring the door, and it also causes it toslide easier. tral.

A slightly nodified construction is shown Its use, however,1is not essenin Fig. 7 in which 23 represents the'doorund24 the plate on the exterior of the same,

which in this case is also formed with a sleeve 25. In this construction the sight door 26 corresponding to the door 6 is shown on the exterior side of the door 23, the same being pivotally hinged or supported at 27 in any suitable manner. A latch 28 arranged to engage lug 29 or equivalent, means maybe provided forlocking the small door shut, and I have shown the spring 30 tending to normally maintain the latch in look ing position. In this case 31 represents a frame at the inner side of the dobr, 32 the slide and 33 the transparent pane. Fig. 8 is intended to illustrate how the plates at the inner and outer sides of the door may be secured together by common means, and in such a manner that a plate at the exterior side cannot be easily removed. Referring to this figure, 34 represents the outer plate and 35 the sleeve, while 36 represents screws or bolts which may take the place of the screws 4 previously described, but which extend through and engage thethreaded lugs 37 or the equivalent, therebyisecuring the two provided with the glass panel 42, and 44 a small sight door corresponding with door 6. In this case door. 44 is secured to frame 41 by a pin 45, 46 being a coil spring so arranged as to tend to throw the door 44 shut and'maintain it in its closed position.

Vi hile it will be obvious that my attach- I ment may be made in various sizes, I prefer 'to make the same substantially of the size shown, which is amply sufficient for the purpose of conversation or observation, or for the passing through of a card or small article, and still of such sizes that one at the outside cannot extend a hand through the same. By providing the doors with shutters, greater privacy is obtained in the interior, and it is not possible for one to reach in by means of instruments and manipulate the door lock or knob. When one at the outside approaches and by means of the doorbell,

telephone or knocking, or otherwise attracts the attentionof the one at-the inner side of the door, the one on the inner side may open the sight door 6 or its equivalent and observe who is without. If desired they may con verse through the glass, but ordinarily it is preferred to raise the slide, especiallyif the one from the outside desires to pass a card to the one within or vice versa. There is no chance for the one without entering until the door is opened. Without my device it would be necessary, in order to see the one without, to open the door, in which case the one from without might place a foot, cane or something else in the crack of the door, thereby preventing the occupant or one at the inner side from closing the door. This is even true with chains or bolts, as the door can be prevented from being fully closed by the one at the outer side. The device is therefore particularly desirable in residences, apartment buildings and the like. It is also desirable for the same reasons in hotels, each room door being equipped with one of the devices. The same is also convenient as the one wlthin can observe who is without and converse even 1f not entirely clothed or otherwise not presentable. The one from without likewise is not able to make any observation of the interior of the room, as the sight door 6 may be only partially opened a sufi'icient distance to satisfy the one at the inner side. The device is especially attractive as well as convenient and safe. In apartment buildings, while they are generally equipped with phones or speaking tubes, and peddlers, tramps and others are supposed to be kept out of the interior halls by outer doors, these people frequently gain admittance to the interior halls, in which case the one within the apartment having doors equipped with my devices can always first observe who is outside before opening the door, as well as converse if it is not desired to open the door.

Having thus described my invention, it is" obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention,

hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. In a door attachment of the kind de scribed and in combination, plates arranged to be placed on the exterior and interior of the door, a two part tubular sleeve arranged between said plates, a sight door member pivotally carried by one plate for normally closing the opening through said sleeve, and a transparent shutter slidably arranged between said plates adjacent the sight door, and means carried by the sight door for looking said transparent shutter in position.

2. A door attachment of the character described,- comprising" supporting means located at one side of the door, a sight door movably attached to said supporting means,

a transparentshutter located adjacent the sight door and adapted to be maintained in:

position for a movement, said sight door and shutter being capable of independent relative movements, and means carried by the by the sight door and cooperating with the shutter for maintaining the closed position.

4. A door provided with an opening therethrough anoadjustable tubular sleeve ar ranged in and closely fitting said opening, plates arranged on the inner and outer sides of the door at the'ends of said sleeve, and provided with openings to permit observashutter in a tion through the door, a sight-door arranged. at the opening through the inner plate, re-

silient means, for retaining said sight door closed, a transparent shutter slidably arsupporting means i ranged between said sight door and the sleeve, and m'eanscarried .by said sight door for locking said shutter against movement when the sight door is closed.

In testimony whereof, I have hereunto signed my name in the presence f t bscribing witnesses. I
