BUSHING Original No. 1,641,988, dated September 13, 1927, Serial No. 696,426, filed. March 3, 1924. Application 101 reissue filed April 5, 1929.

This invention relates to bushings. The obJect of this invention is to provide a i bushing having a resilient bearing portion illltOH'lQbll door showing the application of tltitlptfifl to support a shaft or the like out of contact with the bushing and a portion arranged for insertion in and attachment to a bored structure, said portion being the sole i Preferably the head portion and attaching portion of said bushing are made integral or one-piece, but not necessarily, and said attaching portion is preferably made to be secured in .the bored structure by distorting or expanding it, though not necessarily.

An important feature of my invention is that it hasa wide field of usefulness and may be used in combinations where it is impractical or impossible to use other forms of bush .25 ing 's. Thus I have found the within described bushing to be particularly well-suited for mounting on a door and supporting the shaft of a latch mounted on said door. v

Another importantpoint about my bushing is that it may be quickly applied and is inexpensive to make, as well as having other advantages which will be pointed. out hereinafter.

The said resilient-bearing is preferably waterproofed, and should be capable of making a water and dust-tight fit around a shaft or other element, though in some instances this may not be necessary. 1

The act-o1npanying drawing discloses a preferred embodiment and several modifications of my l'iushing, as well as an application thereof.

Serial No. 352,873.

Fig. 4 is a side View of the bearing or washer; Fig. 5 1s a horizontal sectional view of-an a. modified form of bushing to said door and to a modified latch-actuating handle; and

'Fig. 6 is still another form of my bushing. While in the following description I shall describe my device more particularly with respect to its application and use in connection with latch handles for automobile doors, it will be apparent as this description proceeds that such device likewise may be applied to various analogous uses where a simple and efficient bearing support or bushing for an opcratinp shaft extending through an openingg, in a door or other structure, is desired. In such cases where the shaft is operatively connected at one side of the structure to a part to be actuated thereby, the opening receiving the shaft is often carelessly drilled, so that when the shaft is positioned therethrough, its axis will not exactly coincide with the axis of said opening, but said shaft will be more or less eccentrically related to 75 the walls of said opening. Heretofore in such instances it has been quite diflicult to properly fit and support the shaft in a bearingarranged at the opposite side of the door structure without severe binding or frictional resistance to the turning movement of the shaft, or without providing a bearing support or bushing of relatively complicated and expensive construction.

For purposes of illustration, I have shown as my present improvements as applied for use in connection withan automobile door 5 to' the inner face of which a suitable latch means having an oscillating rollback 6, is applied' Smcetlns latch constitutes no essential feano ture of my present improvements, it may be of any-desired construction. The rollback 6 is actuated by the usual handle 7 having a cylindrical shaft 8 terminating in a rectangular shank portion 9, the end of which is fitted into the bore of the rollback 6 and rigidly The-means for fastening or securing the handle shank to the rollback likewise constitutes no essential part of the present improvements, and such fastening 10g 1,484,406, issued. February outer end in concentric relation to the axis of the rollback 6, the end of said opening at the other side of the door will be eccentric with respect to the rollback. Therefore, when the handle shaft 9 is fitted through said opening and connected to the rollback 6, the axis of said shaft will not exactly coincide with the axis of the opening 11 through the door.

Accordingly, if a rigid metal bushing were fitted into the outer end of the opening 11, it would not have uniform bearing contact upon the periphery of the handle shaft and unless said bushing is especially formed in accord ance with the degree of eccentricity of the shaft with relation to the opening 11, it would not be possible to properly fit the shaft in said bushing without severe frictional binding engagement tending to retard the free rotation of the handle shaft.

In my Patent No. 1,540,495, issued June 2, 1925, I have shown, described and claimed a combination escutcheon and shaft bearing member, wherein the metal escutcheon is provided with means having direct bearing contact upon the shaft and in which a part of said member is expanded under pressure into the structure of the door whereby thememher is fixed permanently inposition. In the present case, I likewise provide a sheet metal escutcheon member or bushing 12. This member in one embodiment consists ofa one piece metal sleeve or tube having a portion 13 adapted to project into the outer end of the handle opening 11 in the door structure and a diametrically enlarged hollow annular head 14 at one endof the portion 13 of said sleeve. This head is adapted to receive an annular compressible bearing element 15, and as shown in Figure 2 of the drawing, the outer flange or wall of the annular head 14' is turned inwardly and downwardly over and upon the-annular element 15 and at its edge has gripping or binding contact therewith,

as shown at 16, whereby said annular bearing element is permanently confined withinthe annular channel of space of the head 14.

Preferably, the annularbearing element 15 is composed of a high grade of felt of suitable texture and is impregnated withan animal oil for the purpose ofrendering the same substantially waterproof. In applying this combination bearing and escutcheonto the door structure, I may use a tool somewhat similar tothat shown in my patent last above referred to, whereby tongues or. spurs .17 are struck outwardly from the end edge of the part 13 of the bushing which projects into the opening 11 and are firmly embedded in the door structure 5 whereby the bushing is permanently fixed in position upon the door. If desired, the tool may be so formed as to embedthese spurs 17 in the door structure at the same time as the 'flange 16 of the bushingis turned inwardly upon the bearing element 15. Itwill be noted that in this instance, the element 15 completely fills the annular channel of the head 14 of the bushing, the inner diameter of the annularmember 15 being predetermined in accordance with the diameter of the handle shaft 8. Since, however, the structure of the bearing element 15 is inherently yleldable and compressible, it will be apparent that as the shaft is forced through said bearing elebore of therollback 6, said annular bearin element 15 in the inner portion thereof wi l automatically accommodate itself to anyreasonable eccentric relation which said handle shaft might bear with respect to the head of the bushing or the wall ofthe opening 11, due to the-inaccurate boring of said openlng through the door so that when the handle pensating bearing support for the handle shaft effectively subserves the purpose in view, and in addition to providing an adequate and firm sup ort for the'shaft, while permitting of its ree turning or rotating movement in the opening of the door structure, the compressible bearing element of felt or other equivalent'material affords a substantially dust and watertight closure between the handle shaft and the opening through the door. Further it will be seen that my invention is adapted to be used in connection with the'ordinary type of latch handles now commonly ap ied uponjautomobiles and no additions'or c anges 1n the structure thereof are necessary. Since it is also manifest that the bushing iii-which the hearing element is confined may be produced by means of a simple sheet metal stamping operation, the device asia whole will be, therefore, inexpensive.

My new method of application of the combined bearing and bushing to the door structure further reduces cost incident to assemblage of the latch in the door by reason of the fact that all. fastening screws or other additional elements for thispurpose are eliminated. V

It is to be noted that the sole means for retaining the handle shaft in connection with the door structure is the means for fastening as ment and the end of its shank 9 engaged 1n the the inner end of the shaft in the bore of the rollback. The yieldable bearing member located at the outer facc of the door therefore constitutes the sole supporting means for the I ated. Preferably, as seen in Fi 1 of the drawings, the thickness of the yie dable material of which the bearing member 15 is formed, is appreciably less than the diameter of the shaft receiving opening in said member so that notwithstanding the fact that this material is of a high grade of wear resisting felt having its fibers more or less closely united, said bearing member will automatically adapt or accommodate itself to an appreciable degree of eccentricity in the relation between the shaft and the axis of the opening 11 through the door.

In Fig. 5 of the drawing Ihave shown the device in a slightly modified construction as applied to another type of latch havinfi a vertical operating shaft or spindle 8. This shaft extends above the upper edge or sill of the door structure 5 and to the same a suitable handle 7 is attached. Between this handle and the upper edge of the door my improved bearing and es'cutcheon member or ushing is disposed. The bushing of sheet metal is substantially identical in its construction to that previously described and is applied to the door structure in the same manner. In this instance, however, the annular member 15' of compressible material is of somewhat less diameter than the internal. diameter of the hollow annular head 14' of the bushing. Thus said annular bearing member may shift diametrically within said hollow head when the end of the shaft 8 is inserted therethrough, in accordance with the degree of eccentricity of the shaft end with respect to the opening through the door structure. At the same time, the opposite walls of the hollow annular head of the bushing prevent any axial movement of the bearing element 15' so that in such lateral shifting of the bearing element the inner portion thereof will be placed. under compressing pressure. However, it will be apparent that the same result is obtained in this case as in Figure 1 where the shaft extends transverse- 1y through the door, and a combined water and dust-tight closure for the end of the shaft opening and an adequate bearing support for the handle is provided.

In Figure 6 of the drawing, I have shown another alternative form of the device, wherein the bushing or escutcheon member consists of a body section13 in the form of a short metal sleeve or tube having an angular flange at one end providing an annular channel or groove to receive the compressible bearing annulus. The .outer wall of the flange 13 is threaded to receive a flanged cap section 13", the radially disposed wall of which has clamping and bearing pressure against the outer side of the bearing annulus 15 whereby the latter is tightly secured in place. If for any reason this hearing annulus should become loose, the cap member 13 may be further adjusted so as to increase its pressure upon said annulus.

From the foregoing description considered in connection with the accompanying drawing, it is believed that the construction, manner of use and the several advantages of my present improvements will be fully understood. It will be appreciated that by eliminating the contact of a metal bearing or supporting part with the shaft, wear of the latter is substantially obviated and also any metallic rattling noise due to vibration is wholly overcome. I have found that a high grade of felt of the proper texture and of great durability may be obtained which will be substantially immune to deterioration by the elements, temperature changes or analogous causes, and will practically retain its functional capabilities unimpaired for an indefinite period. I have illustrated and dcscribed several different constructions and applications of my invention, but no unnecessary limitations are to be implied therefrom, since it is apparent that the device might also be exemplified in other alternative constructions and applied to many other analogous uses.

Accordingly, I reserve the privilege of resorting to all such legitimate changes in the form, construction and relative arrangement of the severalparts as may be fairly e1n bodied within the spirit and scope of the invention as claimed. v
