For reasons, fully y o -pending application, beare offthis type are relatively exandfconsiderable time andvv skill v` gth'e bearing member in place. It reque'ntly happensl that the opening ghfthe door is notl accurately centered thfefrol'lback and in such cases the solid metal bushing offers considerable frictional v'resistance-to vthe `free turning movement of4 the'ilatch handle. I have succeeded inolvervcoming these diiiiculties by providing a latch handle bearing member as shown in my prior application and which Iconsists, in its preferred vform, ot a one-piece sheet metal sleeve) 5 having an enlarged hollow annular head'f formed on one end thereof to surroundA the latchI handle opening 8 at the outer face of the door 7 and subscrve theV purpose of an escutcheon., Within the hollow annular head 8 the annular bearing element 9 of felt or other compressible material is secured.

Upon the inner side of the door structure 7, a suitable'latch, partly illustrated in Figure 1. of the drawings, is secured, said latch including the usual actuating rollback 10 having the handle receiving bore 11. It is the intent in the manufacture of such automobile doors to accurately bore the opening 8 thercthrmlgli so that when the latch is apv plied the bore 1l ofthe rollback 10 and the is Ea 1 horiaontal sectional view Ahor zontal section-.taken on.

eX'pendedin `properly attaching and opening 8 will be coaxially centered with respect to each other. Not infrequently, however, due to carelessness, either in applying the latch to the door structure or in oring the o ening 8, such exact coaxial alignment of t e rollback bore and said opening is not obtained and the axis of the openingB may extend at a slight angle with respect to the axis ofthe bore 11. l Furthermore, as shown in Figure 1, the opening 8 may extend through the door structure at an angle of-` -v oth'er than 90 with-respect to the outer face of said door.

In applying the sheet metal bearlngand escutcheon member, the end of the sleeve 5 which has an outer diameter approximately equal to the diameter of the opening 8, is inserted into. the outer end of said opening until -the inner side of the annular head 6 contacts with 'the door face. This bearing member is-then permanently fixed in osition by rmeans of my improved toolwhic in its preferred embodiment, is ot' the following construction:

The tool body 12 is preferably, though not necessarily, of rectangular form and one end of this tool body is provided with the longi- -tudinally extending slots 13 disposed in v will be presently ri htan ot er. he body 12 'is further formed with a longitudinal bore 14 communicating with said `slots at one of its ends and having its other end counterbored or enlarged as at 15 to provide an internal annular shoulder 16.

the longitudinally extending concave.

' 21v is formed and said body portion is provrvided atV its other end and at the inner side thereof with a longitudinally projecting arm 22. This arm may be of any suitable form, but as herein shown, is slightly curved or flared outwardly and at its extremity is provided with a spur or tooth 23 of suitable form or shape.

As. clearly shown in Figures 2 and 6 of the drawing, the shank portions 20 of the tool elements are arranged in the slots 13 between the spaced arms 18 of the tool body,

said-tool elements being disposed in diametrically op ospite relation to each other and each of t e shank portions having an opening therethrough to loosely receive a pivot pin 24 which at one of its ends is provided lar intersecting relation to each with a threaded head 2510er engagement in the threaded opening 26 of one of the arms 18, while the other end of said pin is seated in a recess 27 provided in the side face of an opposed arm 18. The shank 20 of each of the tool elements at the inner end thereof is formed with a convex cam face 28.

The actuating means for the pivotally mounted tool elements consists of a rod 29 having a part of relatively small diameter extending between the several tool elements and withl which the concave faces 21 of said tool elements engage in the normal position of the parts.` This rod at the outer end oi` said portion of small diameter terminates in an enlarged `interiorly threaded portion 30 which is connected with said small diameter section of the rod by a tapering or conically' the tool elements, a second conical or taperedcam portion 33 is provided and connects said portion of the rod with the'part 34 thereof of relatively larger diameter which is slidingly engaged in the bore 14 of the tool body. This part 34 in turn at its other end has an enlarged head 35 slidingly engaged in the counter-bore 15. The part 34 of the rod is provided with a longitudinally extending keyway 36 receiving the inner end of 1the screw 37 which is threaded in the tool body and thus prevents turning or rotative movement of the rod relative to said tool body. A threaded .member 38 is engaged with the thread 17 vin the end of the tool body so that the distance between the end of this member and the annular shoulder 16 deteriii'ihs-tlie vpossible extent of `longitudinal movement of the actuating rod 29 in either direction. A lock nut 39 threaded upon the member 38 aga-inst the end of the tool body secures said member in its adjusted position. This member has a longitudinal bore 40 loosely receiving the stem 4l projecting from the head 35, the end portion of said stem extending beyond the member 38 being threaded to receive the 'internally threaded cylindrical nut 42. This nut is provided with an annular flange 43 on the end thereof opposed to the member 38 and is loosely confined for rotative movement relative to vsaid member by the couplingr element 44 t-hereto by a suitable set-screw 46. An operating handle 47 of any desired form 1s fixed to the other end of the nut 42 In the use of my improved tool` as above described, after the sleeve 5 has been insert-v ed in the outer end of the opening 8 in the door, as shown in Figure 1, the nut 42 is turned until the cam part'33 of the rod 29 engages against the convex cam surfaces 28 of the tool elements so that said tool elements are moved to the position shown in Figure l of the drawings wherein the inner 'faces 21 of the body portions of said elements are substantially engaged upon the periphery of the rod 29. In this position of the tool elements, it will be observed that the diameter of a circle touching the points of teeth 23 is slightly greater than 'the internal diameter of the compressible bearing element 9. Thus it is necessary to apply considerable pressure to forcev these points or teeth through said bearing element and within the inner end of the sleeve 5 to the posil tion shown in Figure 1 of the drawing, wherein the ends of the body7 portions 19 of the tool elements bear against the outer side of the escutchon head 6 on said sleeve. The

,rod 32 being positioned through the bore of the rollback 10 serves to support the weight of the tool during this positioning of the tool elements. The body ofthe tool is firmly grasped so as to maintain pressure against the escutcheon head 6 and hold the edge thereof at its inner face in tight contact against the face of the door at all points around the opening 8. The nut 42 is then turned in the proper direction by means of the handle 47 and the rod 29 is moved from the position shown in Figure 1 to that illustrated in Figure 2 of the drawing.

In this movement of the rod 29, it will be evident that as the conical cam portion 31 of said rod is drawn between the inner flaring or convex surfaces of the arms 22 of the tool elements, said arms are forced outwardly, the tool elements rocking freely upon their respective pivots 24. Under this expanding pressure, the points or teeth 23 on the arms 22 force the meta-l sleevewall outwardly at diametrically opposite points to provide the protuberances 5 therein which are firmly embedded in the wood structure of the door and eflectually prevent an possibility of the sleeve working loose an( moving outwardly through the latch handle opening 8. This expanding movement of 'the tool elements is limited by contact of the enlarged part 85 of the rod 29 with the end of the element 38. Bv now reversing the rotation of the nut 42, the rod 29 is shifted in the opposite direction and when the conical cam part 33 thereof rides upon the cam surfaces 28 of the shanks 20 of the respective tool elements, said elements are again rocked upon their pivots 24 and positively eff returned to their normal positions,'the `arms 22 of said tool elements moving inwardly as A the conical cam portion 31 of the rod moves outwardly between said arms. Thus the points of the teeth 23 of the armsare disengaged from the Wall of the bearing sleeve and said arms may then be withdrawn through the compressible bearing element 9. T he latch operating handle may' now be easily and quickly fitted in position through the bearing element 9 and connected with the. rollback 10 and since said bearing element is composed of compressible material, it will automatically accommodate itself to any misalignment between the axis of the.` opening 8 and the axis of the latch handle, thereby providing'a proper bearing sup ort for the handle at the outer face of t e door while reducing frictional resistance to a minimum.

By means of my improved tool it will be apparent that such sheet metal bearing members may be very quickly fixed to the dootI structure with the assurance of a definitely accurate relation between`said bearing element and the latch rollback. `-It will be seen that I have avoided the use of springs or other non-positive and easily breakable parts for returning the tool elements to normal position and provide a positively acting cam means for this purpose so that the positive simultaneous disengagement of the points or spurs 23 of the tool elements from the wall of the sheet metal bearing element is assured.

From the foregoing description it will be seen that I have referred to the attachment of the bearing member by means of my improved tool to .a door structure of wood. However, it is evident that the same tool,

with slight modifications in the form of the arms 22 and the bits or points 23 thereof, may be employed forvattaching and securing such a sheet metal bearing member to a metal door structure. In such case, the end of the metal sleeve might be bent or flanged over at diametrically opposite points/by suitably formed bits or teeth on' the ends of the.

arms 22 upon the inner side of the sheet metal door structure and forced into recesses formed in the edge of the opening in the door. Since the necessary changes in the tool to permit of such application of the bearing member to a. metal door could be readily made by the skilled mechanic. they are not herein illustrated in detail. It will further be understood "that though I have herein referred to a simple and satisfactory means for actuating the individually movable tool elements, this actuating means as well as the detail construction of the tool body and the manner of mount-ing the tool elements therein might be exemplified in various other alternative structures. cordingl y, I reserve the pri vilege .of resorting to alll such legitimate changes in the form,

construction and relative arrangement of the several parts as maybe fairly embodied ltool body, a lurality of tool elements hav- .end of each tool element being ing reduced s ianks at one of their ends pivotally mounted in said slots for radial movement relative to the tool body, the other provided at the inner side thereof with a ongitudinally rojecting arm inclined outwardly with reation 'tothe actuating member, one end of said actuating member projecting beyond said arms and having a cam surface adapted to engage the inner faces of said arms upon axial' movement of said member 1n one d1- rection to radially expand said tool elements,

said actuating member being also provided with a second cam surface to' coact with the Shanks of said tool elements upon an axial movement of said member in the o posite direction to move the outer ends of t e tool elements inwardly, and means mounted upon.V

the tool body for manually operating said actuating member. f
