Be it' known that I, O'rro ALrsqrrUm-acitizen of the United States, residing -in Chicago, county of Cook, State of Illinois,
have invented, a certain new and useful Improvement in Service Doors, and declare the ifollowing to be a full, clear, and exact:
description of the same, such as will en' able'others Skilled in the -art to which it ertains to make and use the same, reference being had to the accompanying drawings', which form a .part of this speciticatioii.
The present invention relates to doors such as are now used to some extent for the outer doors in the rooms of hotels, into which clothing or other articles may be deposited by the occupant of the room to be removed by an attendant without gaining access into the room. The object of the present invention is to produce a door of thiskind of simple construction. l
Doors of the kind under consideration have heretofore been provided with two auxiliary doors enclosing between them; a compartment orjchamber; one of the auxiliary doors being for' the use of the occupant and the other for theuseof-an attendant positioned outside of theroom to I'which the door leads. This necessitates a special construction for the main door in order to giveit the requisite strength to resistfsagging, it requires hard ware, including two sets of hinges, forthe two auxiliary doors,
some and expensive. Furthermore, unless special lockln' provislons are made, 1t l1s possible that t e attendant may gain access to the room by being able to open the inner as well as the outer auxiliarydoor.v
Viewed :in one of its aspects, -my invention maybe said to have for its object to produce a simplejand novel door of the" onlyva type under `consideration `havin single auxlliary. door, the cham er bein provided by .the displacement of the centra panel of an'ordinary door out of the lane" of thelatt'en; the panel serving not on y as a structural" strength-giving element, but positively preventing'anyone from assing through the main door withoutopemng the;
latter.
In carryingout my invention, Igemploy; a main door ofthe type having a lar econ! theou'ter side' wallfv boundin -thej groove,`-;
'the? dooria Y. bead-li e continuous]'projection `itliat ref@ tralv anel bounded by four st1les.v nstead o fLa xed central ariel, I substitute-an auxiliary door adapte -to be on.` the outer" sfide vopening 'in ythe latter. 'provided for lookin lthe door,
door,
f wherein:
Figure 1f is an elevation of the inner side cfa doorarranged in accordance with my invention, a 'fragment of the surroundingv vdoor frame vbeing shown; iFig. 2 is a section and the door as a whole 1s therefore cumber- .y i

When anattenda'nt desires'zto gain access tothe compartment in panel in the form of av s hallow enably of metal, fastenedatfits e stiles of .the main door around by a suitable knob or handle, and'from the desires to lary lowing-detailed description taken in connec- .tlon with g the accompanying drawings,
through the door taken approximatelyv o n line 2`2 of Flg. `1; Fig. 3 1s a section, on a somewhat enlarged scale, taken approximately on line B-S'of Fi 1; Fig. 4 is a view similarv to Fig. 1, showing the outer side of the door; Fig. 5 vis a view on an enlarged scale showing a fragment of the inner side `of the door at the point where the latch is located and Fig. Gis .a section taken approxi`` -matel von line6-6 of. Fig. 5'.'
f. l Re erring to the drawings, '1 and 2. re Aresent theverticalv Stiles and 3 andlwt e v topand bottom stiles'of'a single'panel door,
these .stiles v forming "a frect'angular .'frame havingalarge'centralopening;1 This oper, ;ing,in the ordinary door, is filledfwith,-v panel `thatfts infgrooves Cutinto the'v inner 5 i edges of the `st`iles'.'---Instead4 of s employing.A grooves inthe stiles, Ifcut away that; portion ofeachstilethat intheordinarydoor forms v11ol leavin onv thelzinner side o is characterizedl will hereinin'g to the hinged edgeof the main door;
but, while the hinges 7 of the main door are so disposed that the latter swings inwardly, the hinges 8 for the auxiliary door are so arranged that the auxiliary door swings outwardly.
At the free Vertical edge of the auxiliary door is fastened a plate 9 projecting inwardly at right angles thereto and havmg a hole 10 therein near its ifree end. lThe rib or bead 5 is out away, as indicated at 11 in Fi 3, permitting this plate to swing inwarly past the same when the auxiliary door is closed. On the inner side of the stile carrying the lock and the knob for the main door is placed a latch device 12, which may be an ordinary ni ht, latch having a bolt 13 ada ted to pass xrough the hole 10 in the loc ring plate 9 on. the auxiliary door. This night latch may be o erated from the inner side of the ,main oor by means of a suitable knob or handle 14. A'l
tumbler device 'or other suitable fitting 15 extends through the main door to the outer side so that, upon the insertion o f a `key in the device 15, the auxiliary door may be unlocked from the outside and swing outward by grasping knob 21. y
O n the inner side of the main door is fastened a. panel in the form of a shallow pan 1 6, preferably of sheet metal, slightly larger than the panel opening in the main' door, so aslcompletely to cover this opening, Thebroad vertical face of A the panel, is preferably llat as are also the top and"bot` tom sides, whereas the two long vertical sides m^ay be inclined somewhat for the sake of neatness'. While the Ipan may be attached in any suitable way, I prefer to provide it with a laterally-projecting flange 17 -extending around the mouth thereof; this flan e being parallel with the inner surfaces of t e door stiles. In order to preventthe transmission of vibrations directly from the wood to themetal, I prefer to place between the flange 17 and the door` Stiles a layer of felt 18 or other sound-deadening cushioning material. After the pan has been placed in position, with the cushioning element between its flange and the door Stiles, it may conveniently be fastened 4in place by means of screws 19 passing through thellange and into the ,wood ofthe main door. Instead of making the flange on rthe pan flat, it is preferably made in thel form of a rounded trough the concave side of which is directed toward the door. This not only strengthens the exposed ed e of the sheet metal and prevents them rom being damaged, but it also permits-the substantial concealmentof the cushioning material, since the extreme edge of the flange may be brought quite near to the surface of the stiles, vas'long as it remains out of contact with such surface.
As best shownin. Figs. 5 and 6, a small section is cut out of the side wall of `the pan'in the vicinity of the latch, to provide a hole 20 into which both the'plate 9 on the auxiliary door and the ybolt 13 may project.l
,it 'will be seen that the main door opening is stillclosed as-completely as it'would be by anordinary door. K This is the condition existing during the time `an attendant is placing articles in or removingfthem from the compartment enclosed between the panel 16 and the auxiliary door. When the occupant ot' the room wishes torgain access to this compartment, the main. door ris swung in the clockwise direction as viewed in Fig. 3, so that the auxiliary ldoor when it is open to the same extent as shown in Fig. 3, lies in and closes 'the' greaterportion of the main door opening and'thus serves as a screen between the room and the corridor.
The auxiliary door may be provided near the top with a hook 22 or other supporting member, projecting into the compartment in the device, on which articles of clothing may be hung. Thusclothing may be placed in or removed `from the compartment without the necessity of reaching into the com partment. A
While I have illustrated and described with. particularity' only a single preferred 1. In combination, a main door having a large central stationary panel displaced out of the plane of the door to produce a recess in one side of the door, an auxiliary dooi` hinged to the main door to form a closure for the said recess, a member secured to the auxiliary door near one of the edges at a point remote from the hinged edge and projecting into the rear portion ofthe recess when the auxiliary door is closed, said member having an opening therein near its free end, a manually-operable latch secured to the main door on the opposite side from-that on which the auxiliary door is mounted, said latch having a bolt adapted to enter the openlock the latter in its closed position, and
there being a keyhole for permitting the latch to be operated by a key from the side of the main door on which the auxiliary door is mounted.
2. ln combination, a main door having a large central stationary panel displaced out of the plane of the door to produce a. recess in one side of the door, an auxiliary door hinged to the main door toform a closure t'or said recess, a keeper secured to the auxiliary door and positioned in the recess when the auxiliary dooruis closed, a latch secured to the main door and cooperating with the said keeper to lock the auxiliary door in its closed position, and means for operating said latch from veither side of the maindoor.
3. ln combination, a main door composed of a body member in the form of an open frame, a sheet metal member in the form of a shallow pan larger than the opening in the frame and having a marginal flange extending around the same, a layer of cushioning material arranged between said flange and the said body membenjastening means passing through said flange into the said body member, and an auxiliary door fitted in the opening in and lying in the plane of said body member.
4. The combination with the doorway for a room, of a main door hingedly mounted in said doorway to swing into the room, a compartment forming structure permanently secured to the inner side of the main door, said main door and compartment forming structure having registering openings formed therein, whereby access to the compartment must be had from the outer side of the main door, and an auxiliary door carried by the main door to control access to the compartment, said auxiliary door being hinged on the edge corresponding to the hinged edge of the main door but to swing outwardly in respect to the said room to permit being moved into a position to obstruct the doorway when the main door is open.
In testimony whereof, I sign this specifica.-
