SHEET-METAL noonFnAME 'ooivsclnnuefrroiv This inventionfrelates tothe latch plates for locks of variouskinds and classes and k particularly to devices of this class mounted 1n and constituting part of the door frame Ject-matterof my prior application filedl construction and in connection with which the latch bolt of a lock mounted on a door is adapted to operate; and the object of the invention is to provide a. latch plate with means for quickly attaching the same to the door .f frame and rsupporting the' same in an aper- Y ture 1n said door frame 1n such manner as to come in alinement with the latch bolt of alock mounted on the door hingedly 'sup'- ported in said door frame, the mounting of said'latch bolt being such as to permit of the quick attachment and detachment thereof, at will, and further to permit ofvits adjustment or reversing of the position thereof in the door frame to compensate for varying heights of the latch bolt on thedoor to bring theplatch bolt receiving aperture ofsaid plate in proper alinement withthe bolt of the door; a further object being to provide a. latch device of the class specified which is primarily adapted for use in sheet metal door frames, the door frame being fashioned tok seat said plate with theouter face thereof flushV with the outer face of the adjacent walls of the door frame, said plate having a movable device or devices adapted to engage the door frame to retain the same againsty accidental displacement; a further object being to provide a-klatchplate, which by virtue of its construction vand use will permit of the construction' of standard sheet metal door stock'frames in stock sizes with a [universal adaptation of a latch plate to said standard stock sized door frames, eliminating the necessity of constructing door frames specially for each individualfbuilding construction at the time of giving contracts therefor as is the usual custom, said standard frames being provided with an aperture of universal common form and dimensions to permit of the 1 provided with one elongated'flatch bolty remounting of suitable latch plates in connection therewith;v and with these and other objects'in view, thev invention consists in a device of the class and for the purpose speci- `fied, which is simple in constructionand oping yanother modification.

eration, efficient in use, and' which is constructed as hereinafter claimed. f

This invention constitutes divisional sub- J une 22, 1926,'Serial No..117,679, and is fully disclosed in the following specificatiomof which the accompanying drawing forms a part, in which the separate partsv Iof my improvement are designated by suitable reference characters in each of the views, and in whichz Y' Fig.' 1 is a perspective view. of a part ofa door frame showing one ofV my vimproved latch plates mounted in connection therewith.' v Y Figxfla is aview similar toFig. v1 but showing the latchplate mounted in areverse position, l

Fig. 2 is a partial section on the-line '2--2 of Fig. land on anenlarged scale. y Fig.I 3 is a back view of the latch plate detached and indicating the manner -ofy its mounting inl a-door frame. y

Fig. 4 is a view similar to Fig. 2Y but showing ai modification and,

Fig. 5 is a view similar tofFig. 4 but show-l vIn Fig. 1 of the drawing, I have shown for thepurpose of illustrating one method of carrying my invention into eect a part of a sheet metal door framelwhich may be of any conventional cross sectional 4form 11 representing the door stop portion vof the frame, limiting the swinging movement of the door in 'one' direction, which formsl at one side thereof, a face 12 to receive the free outer face or edge of the door hingedly lsupported' in the `frame 'in the usual manner. The face 12'of the frame 10 at a predetermined distance above the to receive a latch ceiving aperture 15 which extendscloser to one end 16 of the plate 12 than the other kend vthe height of said aperyture 14 in the vdoor frame'lO may be raised described v and y L yfloor is provided f with' an aperture 13 preferably elongatedV its rear side with a strip 19'secured thereto in any desiredmanner, the edge of said strip projecting beyond the beveled end of the plate 14 to engage the inner face of the part 12 of the frame to retain the plate 14er the end portion 16 thereof ag-ainst displacement,

while a lock or catch device 21 is pivoted to the other end 17 of the plate 14 as seen lat 22 and adapted to extend onto the inner face of thepart 12 of the frame 10 within theaper-v ture 13 to secure the end 17 of the plate 14 against displacement. The member 21 may be moved from the position shown in dottedV lines in Fig. 3 of the drawing to that shown in full lines in Fig. 3 and also in Fig. 2.of the drawing, by a suitable tool passed inwardly through the aperture 15 in the plate 14.

In placing the plate 14 in position in the aperture 13 of the frame, it will be understood that the end portion 16 is rst inserted into the aperture 13 adjacent one endthereof, after which the fotherend 17 of the plate 1'4 is swung into position with the member 21 in the dotted line position shown in Fig. 3 of the drawing, and said member is then turned into the position shown in full: linesas above stated.

In Fig. 4 of thedrawing, I haveshown a modification wherein the part 1 21'of a door frame, instead of being provided with the beveled faces as at 18 in Fig. 2 of the drawing, is offset to form stops 23 and, 24 to limit the inward movement of-a latch plate 25 and to support the latch plate flush with the outer face of the part 12a as clearly seen 4in Fig. 4 of the "drawing, the inner face of the latch plate 25 being provided adjacent thefends 26 and 27 thereof with springclips Y28 adapted to be sprung over the stops 23 and V24 rand toengage the Asame as-seeninFig. r4 to secure the plate 25 against accidental. displacement and yet permitting ofthe forcible removal of said plateV at will. 'The aperture 29'in the plate 25 is arranged in the same'manner` as 'the aperture 15in the plate .1.4 whereby the 'plate may be reversed intheydcor frame to raise or lower the aperture 29. .Inthe above operation of attaching yand detaching, the plate'25, it will be understoodthat the spring clips 28 are sprung inwardly, and the rounded ends of said clipsfacilfitate this.l operation.

In Fig. 5..-of .the .dra,wingylifhtweishownv anof the principles seen in Figs. 1 to 3 inclusive and part of that shown in Fig. 4 of the drawing. In this construction, the attaching plate 30 is fashioned at one end to form a V-shaped notch 31 having a projecting inner flange 32 to engage the inner wall of the door frame, the V-shaped notch engaging a beveled face in the aperture of the door frame as seen in Fig. 2 of the drawing, while the other end of the plate 30 is/provided on its inner end with a spring 33 adapted to engage la stop member-34 on thedoor frame as in the construction shown in Fig. 4. .With this form of construction, the aperture V35 in vtheplate 30 will be centralized in that the plate 30 cannot be reversed in the door frame in the manner .of the reversal of the plates 14 and 25. It will be understood, however, that either the upper or lower end of the plate may be provided with the spring clip 33 as may be desired, the door frame being fashioned to -suitthe con- Y struction employed.l

It will also be understood that my invention is not limited Yto the specific means herein shown and described for detachably supporting the latch plate in connection with the door frame, nor to the lspecific, form of said plate and various other changes in and modifications of the construction herein shown and described may be made, within .the scope of the appended claims, without departingy from the spirit of my invention or sacrificing Aits advantages. n j l I-Iaving fully described my invention, what I claim as new and desire to secure by Letters Patent, is Y v 1.- A sheet metal door framevfashionedto standardize the'manufacture thereof, vone of the side rails of said door frame being provided with a latch plate aperture and a latch plate mounted directly in connection with said door frame and fitting snuglyV in the aperture in the side rail thereof, and means for directly mounting the plate in connection with said frame in two different .positions of the plate in the frame. i

2. A sheet metal'door frame `fashioned to standardize the manufacture thereof, one of the side rails of said `door frame being provided with a latch plate aperture and a latch plate mounted fdirectlyvin. connection with said doo-r frame, and -fittingsnugly in ,the aperture in the side rail thereof, means for directly mounting the plate in connection with said frame in two differentpositions of the plate in the frame, andvopposite walls of said aperture being beveled :outwardly to form seats for correspondingly bevelediedges on said latch plate.

In testimony that'I claim vthe foregoingV as my invention I have signedv my name .this
