Specification of To allwhom it ma yponcem:

' Be it known that I, JAMES A. Glass, acitizen of the Unite'l'States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements" in Doors, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereotl I l v The invention relates to doors having the latch casing housed within them, and bedoors.

In the manufacture of metal doors, such as-are now in quite common use in railway cars and other situations, it has been found difficult to permanently and satisfactorily secure the latch casing within the chamber of the door. The more common expedient of fitting within the door a mortised block to which the face plate of the latch casing has been attached, has been attended with serious d'itficulties in practice, due to the tendency of the attaching screws to work 1oose,the inability to relieve the latch-controlling spindle of thed'uty of maintaining the latch in place, and for other reasons.

casing to the side walls of the door; and the invention consists in adevice as hereinafter described and as illustrated in various forms in the drawings, in which.

Figure 1 is a detail plansection of the door and .door jamb taken above the latch casing, a part of this casing being shown in plan section; Fig. 2 is a detail perspective of the door and latch casing, some parts being removed and some parts being in sec- 7 tion; Fig. 3 is a detail inpcrspectirc of the latch-controlling spindle and of an escutcheon plate, the latter being shown in sective of the door showinga modified form of construction: Fig. 5 is a detail in perspective tion; and Fig. 6 is a detail in pers 'iectivo of the spindle and an escutcheonplate used in connection with the devi i As illustrated in Fig. lihe door shown side or wall plates 10, 11, spaced apart and inclosing a chamber, and an edge Wall i The last-named wall is apertured to permit 55 the insertion of a latch casing 13, which 2 in the wall plate 10, th s plate bemg aper Letter P n Patented Nov. 18, 1913.

may be provided with the usual face plate" 14: and,-if desired, screwed to a supporting plate 15 attached to the inner 'face of the wall 12 and-m'crlapping its opening. An escutcheon plate 16 applied to the outer face of one of the walls, as '11. of the door, and is prorided with a plurality ofstuds, as 17. 18 and 19, which project through this wall. The latch casing 13 is provided 'with a lug, here shown at 20, projecting from the inner end of the casing andengaging the end of the stud 17, to which it is secured by a screw 21, its face plate 14 being held The" wall 10 of the door is apertured, as shown' snugly against the seating plate 15.

at to provide access to the screw 21, and this aperture covered by an escutcheon plate 23 having instanding studs 24, 25,

which are in alinementand telescopic engagement. with the, studs 18, 19. Screws,

as :26, set through the escutcheon plate 23, enter threaded sockets in-the studs 18, 19,-

and drawthe two cscutcheon plates toward each other. The threaded sockets of the studs 18, 19, are of suiiicient depth to permit the screws to be set up so as to slightly compress the plates 10. 11, of the door, whereby these plates by their elasticity serve to securely hold the screws against turning under the influence of jars and vibrations. The latch-controlling spindle :27 may be of any desired form and pa... through the escutcheon plates 16 and '23. The latch is, however, securely held in position by the means described, so that the spindle is .not called upon to maintain it in position, and it is therefore free to turn in its bearings.

In the construction illustrated in Fig. 4, both of the escuteheon plates, here designated by the numerals 28, :29, are provided with instanding' studs for attachment to the lug 20 ot the latch casing. In this stance the securing means is a screw 32 set through one of the escutcheon plates. as 29, through its stud 31, the lug 20, and into the stud fit). with which it iria-kes threaded engagement. 5y making the studs30 and 31 of such length that they dd not normally reach the lug 20, the plates l0, 11, may be slightly com1n'csscd for the purpose of securing the proper spring action for preventing 'the screw from working loose. When this form of constmcthtnis followed, it becomes unnecessary to provide the aperture, as 22,

tured to accommodete: the studs, as M,

which cooperate with the studs 35, 36, of the cscutcheon plate in securing the two escutdieon plates together. s uctimi ","lustrcted in Figs. and 6, the latch casing, here desi noted 37, is provided with a plnraiity oflugs, as 38, 39 and 4:0, each having a threaded aperture for receiving screws, as all, 4172, 4.3, set directly through the side walls 10, 11,01": the door, and tending to draw them up with a compressive action while securely holding the latch casing in place. An escutcheon plate as 44 may be applied to each side of securing screws.
