ROLLER-BEARING.
Specification of Letters Patent.
Patented July 9, 1907.
' To all whom it may concern:
Be it known that l, ELLSWORTH Josnrn EDWARDS, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved Roller-Bearing, of which the following is a full, clear, and exact description.
My invention relates to improvements in roller-bearings, and more particularly to an improved means for spacing and guiding the rollers and for carrying the end thrust, and its object is to provide the same with certain new and useful features hereinafter more fully, described and particularly pointed out in the claims.
Reference is to be had to the accompanying drawings which form part of this specification, in which similar characters of reference indicate corresponding parts in the several views, and in which Figure 1 is a longitudinal section through an axle and wheel, illustrating one form which my invention may assume; Fig. 2 is a plan view of the skeleton frame used to space the rollers and showing the same before it is applied; Fig. 3 is an end elevation of the rollers and skeleton frame; Fig. 4 is a transverse sectional view through the rollers adjacent their ends, and more clearly illustrating the manner in which they are supported in the frame; Fig. 5 is a longitudinal section through a modified form of my invention; Fig. 6 illustrates my invention as affixed to a car axle; Fig. 7 is an end elevation partly in section of the form shown in Fig. 6; and Fig. 8 is a longitudinal section through a modified form of boxing to be used in connection with the form illustrated in Figs. 6 and 7.
Referring to the drawings in which similar numerals refer to similar parts throughout the several views, I have shown in Fig. 1 my invention as applied to a common form of vehicle wheel 1 adapted to rotate on the spindle 2. The hub 3 of the wheel carries two telescoping tubes 4, 5 having shoulders 4, 5 between which the part 6 of the hub is securely held. Pins or projections 7 may be used if desired, to prevent rotation of the tubes independent of the hub. The outer ends 'of the tubes are enlarged and the inner surface of the enlarged portions constitutes a cylindrical bearing for the rollers, hereinafter to.be described, and the inner end of each of said enlarged portions is cut at an angle to form a beveled bearing surface for the ends of the rollers.
The axle shown is the common form of vehicle axle having a tapering spindle 8, and in order to provide a cylindrical bearing surface I secure a cylindrical bearing sleeve 9 to the spindle. .A suitable spacing collar 10 is used on the reduced end of the spindle, to fill the space between the spindle and sleeve and hold the two rigidly together. At the ends. of the bearing sleeve beveled washers 11, 12 and dust guard washers l3, 14 are provided. Between these, thin washers 15 may be used if found necessary to adjust the parts by advancing trance of dust and dirt.
the beveled washers when worn. Around each bearing sleeve near the ends thereof and inclosed within the enlarged ends of the telescoping tubes 4 and 5, are the rollers 16 and their spacing and guiding means 17, which constitute an important part of my invention and which will now be described. Each roller 16 has a cylindrical intermediate portion 18 constituting the main bearing surface, a rounded end 19 and a reduced spindle 20 between the main body and the ends. The spacing and guiding means 17 for the rollers may be formed in various ways, but in the preferred form and the one illustrated, it is formed of two strips of sheet metal having rectangular openings punched therein throughout its length as shown in Fig. 2. The two side portions 22 are connected by cross-pieces 21 and between each two cross pieces each side portion is crimped to form half of a journal box for thespindles 20 of the rollers 16, leaving one side of each cross piece 21 in the plane of the centers of the rollers. Two of these strips or skeleton frames are used, and the two are riveted or otherwise secured together at suitable intervals one inside of the other, so as to hold the rollers in an annular row with the spindles of each roller held between the side portions 22, and the main portion 16 of each roller extending through the rectangular openings between the cross pieces 21. The cross pieces of one or both of the strips 17 may be omitted, leaving merely two rings having crimped or bowed portions to act as journalboxes for the spindles of the rollers.
The conical or rounded ends of the rollers bear against the beveled removable washers 11, 12, and the line around the end of the same rather than limiting it to a point at the center of the end, as would be the case were the faces of the washers 11, 12 at right angles to the axes of the rollers. The dust guard washers 13, 14 are preferably cut away slightly around their circumference, so that they fit partially within the ends of the tubes 4, 5, making a more perfect seal against the en- The end 24 of the spindle preferably extends beyond the end of the bearing sleeve 9, and by providing this end with screw threads and a nut 25, all the parts may be securely held together.
Freedom from lateral movement may be secured by right angles to the axes of said rollers.
I adapt my improved bearing to the axle of a car wheel in the manner illustrated in Figs. 6 to 8 inclusive. The beveled washer 28 fits on the car axle 29 adjacent to the car wheel 30, and against this Washer surrounding the end of the axle is the row of rollers spaced and held in place in the manner illustrated in Figs. 1 to 4. The boxing 31 has a cylindrical recess fitting over the end of the car axle and rollers, and at the inner end of this recess is a beveled washer 32 contacting with the outer end of the rollers. The boxing is firmly secured in the frame of the car truck 33 by bolts 34, 34, or in any suitable manner. 7 If desired, the boxing may be made in two parts as shown in Fig. 8, where one part may be detached on the line 35 without necessitating a complete separation of the parts.
By means of the novel structure hereinbeiore described, the rollers serve the double function of acting as bearings and also in taking all end thrust. By supporting the rollers at both ends, they are always kept in alinement and in their proper place, and it is impossible for one end of any roller to get ahead of the other.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:
