lL AJICl'" ESCUTCHEON AND METHOD OF APPLYING THE SAIWII?.

Application led .Tune 28, 1923. Serial No. 648,394.

To all ywhom it may concern:

Be it known that I, LEON OTTINGER, a citizen of the United States, and a resident of the city, count-y, and State of New York,

have'invented certain new and useful Improvements in Latch Escutcheons and Methods of Applying the Same, of which the following is a specification.

This invention relates toV an improved latch escutcheon and method of applying the same and has more particular relation to such escutcheons as are used in connection With the latches of automobile doors. Heretoforeit has been the practice to provide a relatively long cast metal bushing threaded or otherwise fixed in the outer end lof the handle receiving opening of .the door to provide a bearing for the handle, said bushing having a flange or escutcheon plate formed on one end to engage against the face of the door around the latch handle. However, in view of the fact that the inner and outerI faces of the door are not parallel,

and the wall of the opening does not extend at right angles to the outer face of the door, it is impossible to secure close contact` of an escutcheon plate or flange of uniform thickness against the door face entirely around the opening. In other words,l at one side of the-opening in thedoor the plate Would be' slightly spaced from the door face, un-

less said plate is specially formed and thickened upon one side. Escutcheon members of this type are, therefore, relatively expensive. A so, these escutcheon plates'are provided With openingsvtol receive attaching screws threaded in the door which 1s an v additional item'of expense.

It is, therefore, the primary object and purpose of' my present invention to provide a combined escutcheon and shaft bearing member for door latch handles and a method of applying the same to the .door whereby close contact of the escutcheon against the door face entirely around the opening is assured with a proper accurate alignment of the opening of theescutcheon member with ,respect to the latch actuating rollback to which the handle is to be connected, regardless of the angular relation ofthe wall of the handle receiving opening with respect to the face 0f the door.

In one embodimen-tof the invention, I provide an escutcheon member, which, when applied and secured to the door provides a tangential single point bearing contact for the shank of the latch handle. Preferably,

the escutcheon member is initially in the form of a sheet metal sleeve having an outturned rounded bead or other ornamental formation on oneend thereof adapted to bear against the outer facev of the door around the handle opening therein. In the application of this escutcheon member to the door, I position the same against the door face With the sleeve extending into the handle opening and 'then properly lcenter said sleeve in concentric relation with the latch actuating rollback. While maintaining pressureagainst the outer face of the escutcheon member to hold the edge member thereof closely against the door face, I :then apply anoutward pressure against the inner wall of the inwardly extending part of said member whereby the latter is expanded and the edge thereof is firmly embedded in .the Wood struct-ure of the door. y y escutcheon member is tightly and securely Thus the fixed in place at the outer end of the handle opening Without the use of screws or other supplemental fastening or attaching means. It is another object of my. invention to providea combined escutcheon and handle bearing which is of suchconstruction that it may be used in connection with the various types of latches-now employed' upon automobile doors and Willdecrease the number of operations required in the application of such latches While providing a neater appearance on the outer face of the door around :the latch handle than is possible with the use of such devices now employed in this art." i

With the above and other objects in view, the invention consists in the improved escutcheon member and in the mannerof applying'the same to the door, as will be herelnafter more fully described, illustrated in the accompanying drawing and subsequently incorporated in the subjoined claims.

In -the drawing wherein I have disclosed` severaly practical and desirable embodiments of the invention and in which similar reference characters designate corresponding parts throughout'the several views:

Figure 1 is a horizontal section through an automobile door having a latch applied ment initial form of the escutcheon member -before securing the same in its final position in the door; i

Figure 3 is a sectional view illustrating the centering and expanding tool for the sheet'metal escutoheon member;

Y Figure' 4 is an inner face view of the escutcheon member in its ori inal form: and

Figures 5 and 6 aredetail sections illustrating several alternative forms of thefdevice.

While the. invention to be hereinafter described is more particularly designed for application and use in connection with the doors of automobiles, it will be apparent that the device might also be advantageously used in connection with the-latch handles of house doors and in other cases where it is desired to provide a bearing support for the operating-handle and a neat and attractive lappearance of the outer face cf the door -no essential feature of the present improvements, it may be of any desired construction. v,For the purpose of -this explanation it will suffice to state that the latch mechanism includes an actuating rollback 7 which is suitably mounted in the walls of the latch case for oscillating or. rotative movement. The rollback 7 is operated by -means of the usual handle 8 and as herein shown, one end of this handle is rigidly fixed in the bore. of the rollback by means of the screw 9. Likewise, this'handle attaching means constitutes no essential part of the resent improvements, the same being ful y described and claimed in m co-pending application for patent, Serial No. 613,809, filed January 20, 1923. i

It will be observed from reference to Figure 1 of the drawing that the outer face 10 of the door is not disposed in parallel relation to the inner face thereof. Therefore, if the handle receiving opening 11 is bored through the door withits outer end in concentric relation with the axis of oscillation of the rollback -7, it will be apparent that.

. plate can be brought into close contact with the face 10 of the door only at one side of the-opening V11. Various suggestions have been advanced for remedying this difficulty.

4Thus it has been roposed touse a separate escutcheon plate, oosely mounting the same on the outer end of the bearing bushing, and interposing a spring between said plate and a washer engaging the door around the handle opening. 1t will be apparent, however,

that such a device will be quite expensive ameter of the sleeve 13 is appreciably less than the diameter of the opening 11 and in the application of the member 12 to the door, the edge of the flange or bead 14 is closely engaged against the door face 10 entirely around the opening 11 whilethe sleeve 13 projects into said opening.` While I have referred to the escutcheon member as having the semi-cylindrical bead 14 it will, of course,`be obvious that since this formation of the sleeve end is purely for purposes of ornamentation, the sheet metal plate from which the device is produced might be of greater area and formed with an escutcheon plateor flange extenslon of any deslred ornamental configuration to extend overa greater area of the door face 10.

After the escutcheon and bearing ymember as been positioned, as seen in Figure 2 of the drawin s, the expanding tool 15. illustrated in igure 3, is then applied. This expanding tool may be of any conventional construction, but as illustrated is providedY with a plurality ofV pivotally mounted expanding members 16 between which a co- `noidal expanding head 17 isl arranged. Each of the members 16 has a reduced dee ly grooved or concaved end portion 18. he expanding head 17 is preferably provided with a socket to receive the end of the centering rod '10 which isA detachably fixed in said socket by the screw 20.

In' arranging the expanding tool in posiI tion, the members 16 are positioned against the escutcheon flange or bead 14 with their reduced end portions 18 extending through the sleeve 13. In order to insure'a concentric relationship of the sleeve 13 with the axis of the latch actuating rollback 7, the end of the centering rod 19 is engaged in the boreiof 'said rollback. The expanding tool 15 is then operated to force the members 16 radially outwards() that .their concave end portions 18 will exert an expand-.

ing pressure against the sleeve 13 extending into the o ening 11. Thus this end of the sleeve wil bev outwardl expanded and the edge thereof firmly em edded inthe wood structure of the door 5 around the opening or passage 11 extending therethrough. In this expandin action, it will be understood that themem` ers 16 of the tool bearing against the es cutcheon flange or bead 14 holds the edge thereof in close bearingbcontact against the doorface 10. rIhus at all points around the outer end of the opening 11 the escutcheon flange will be in positive contact with the face of. the door. After the expanding tool is removed the member 12 is then in the form of a tubularannulus open -at `one side thereof with one edge of said open side extending into the opening 11 of the door and embedded in the door structure. Thus, as seen in Fig. 1 of the drawing, when the operating handle 8 for the latch rollback 7 is inserted'and secured to said rollback, the handle shank will have a single circumferential point of bearing contact upon the inner face of the tubular escutche'on at 21. InHFigure 1 of the drawing, I have illustrated the opening 11 in the door having its outer end concentric with the rollback 7, while in Figures 2 and 3 of the drawing, the opening 11 is supposed to have been inaccurately bored through the door so that' its outer end is eccentric to the rollback. In the latter instance, it will be understood that the proper centering of the sleeve 13, before expansion in the end of the opening 11, is essential in order that the shank of the handle may be properl \7 fitted or mounted in the escutcheon and bearing member after its application to the door. 4

In Figure 5 of the drawing, I have shown a slightly modified form ofthe device in which the sleeve 13 is of vgreater length to provide a relatively long straight inter.- mediate bearing portion 21 for the handle shaft instead of the single point circumferential Contact above, referred to. Also, in this case, I may embed the outer edge of the escutcheon bead or flange in the face of thedoor as shown at 22, as well as expanding the inner end edge of the sleeve 13 into the door structure.

In automobile door latches having the solid metal sleeve or bushing threaded into the outer end of the handle opening, such bushing is usually provided with an internal annular shoulder intermediate of its ends against which a shoulder formed on the handle shank seats. In order to adapt my invention for use in connection with latches having such` a shouldered, handle shank, I -may. provide the construction shown in Figure 6 of the drawings wherein the sleeve is rovided at the inner side of the semi-tubular escutcheon flange or bead 14 with anl inwardly projecting annular 'shoulder 23. Th'e reduced end portion of the sleeve indicated at 13* embed its edge in the door structure, and the expanding tool may be of such form as to also contract the semi-tubular bead or esc'utcheon fiangelft slightly and thus enibed the sharp circumferential edge :24

. formed at the juncture' of said escutclieon purpose in view.

is expanded` .ta

Ysaid flange with the Wallpof the shoulder 23 into the wood. These two spaced points of en-V gagement of the metal member` in the door structure provides greater security.

From the foregoing description consideredl in connection with the accompanying drawing it is believed that the construction of my improved escutcheon and handle bearing for door latch handles as well as the method of applying same will be clearly and fully understood. Owing to the fact that after positioning' the escutcheon meniber, 4it. may be lirmlv and securely fixed upon the door by av single operation of the,

expanding tool, it will vbe apparent that the time required in the application of such sha-ft bearing and escutcheon membersis very materially reduced over that necessary in the vapplication .of such devices as are nowV very generally employed in this art. It will further be appreciated that since'I eliminate the necessity of using screws or other fastening members, the cost of this, item of automobile body construction is very -greatly reduced. Also as I altogether discard the threaded bearing bushing heretofore employed, extreme accuracy in the boring of the handle receiving opening il: the door structure becomes -unnecessary so that there will be a further reduction o f time consumed in the application of the latch tothe door. These several items when compared with the total manufacturingcostof the individual seem' quite insignificant2 yet in the aggre- 'gate they constitute an appreciable item of expense.

thus correspondingly decrease hisoverheadl expense.

automobile body I may I I have .referred in the foregoing descripi tlon and illustrated in the drawings several forms or embodiments of my present invention wluch are entlrely practical for the manifest that the might possibly be secured by utilizing a combination .bearing and escutcheon member ofpother structural forms 4than those Nevertheless, it will bev same desirable results herein disclosed. Accordingly it is-to be -v understood that I reserve the privilege of resorting to all such legitimate changes in the several novel features of my present improvements as may be fairly embodied withinthe as claimed.
