SPECIFICATION forming part of Letters Patent No. 567,309, dated September 8, 1896.
Application filed February 4,1836. Serial No. 577,973. (No model.)
T all whom t may concern:
Be it known that' I, ANDREW C. FAENs- WORTH, a citizen of -the United States, residingat Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Ball-Bearings, of
which the following is a specification.
My invention relates to improvements in the construction of ball-bearings generally, though more especially of ball-bearing axles.
In the drawings herewith I have shown my `improvements applied to a ball-bearing axle substantially of the construction shown and described in my application for Letters Pat- Yent of the United States, bearing Serial No.
560,993, and filed August 30, 1895.
Referring to the drawings, Figure 1 is a broken and partly sectional View of a ballbearing vehicle axle and hub with my present improvements of the preferred construction applied thereto; Fig. 2, a section of the axlespindle, showing the inner face of the head or base portion of the spindle; Fig. 3, a rear face view, Fig. l a front face view, and Fig.` 5 a sectional view, of an inner bearing-cone or race member; Fig. 6, an end view of one of the ball-boxes with the balls in place 5 Fig. '7,
a face view of an outer bearing-cone or race member; Fig. 8, an inner faceview of a cap or jam-nut; Fig. 9, a broken view of the end portion of the spindle shown in Fig. 1; Fig. 10, an end view of the spindle; Fig. 11, a similar view of the construction shown in Fig. l2; Fig. l2, a view the same as Fig. 9, but showing a locking-piece of modified form; Fig.13, a broken view of the end portion of the spindle, partly in section, and showing a further modification 5 Fig. 14, an end view of the construction shown in Fig. 13, and Fig. 15 a perspective view of a spring locking-piece employed in the construction shown in Figs. 13 and 14.4
A is an axle formed with a iiange or head A' and a spindle A2. On the spindle at the iiange A' is an annular cone-piece or ball-race member t. The outer end portion of thewaxle is reduced, as shown at s, and provided with a screw-thread e. In the end of the'spindle is a central-threaded socket e2. Iirthe'constructions shown in Figs. 1, 9, l0, 11, and 12 the spindle is provided on its outer side with a longitudinally-extending groove or recess s2. Fitting over the end portion of the spindle is an annular cone fr', also forming an inner ball-race member provided on its inner circumference with a lug r', which,when the cone is placed upon the spindle', enters the groove S3. The engagement of the lug fr' with the groove s2 holds the cone against independent rotation uponthe spindle.
B is a hub, and C a sleeve provided with ball-boxes Cl C2, forming outer ball-race members. In the ball-boxes Cl C2 are'ball-retaining washers q g', which are'large enough at their inner circumference to be out of contact with the inner race members t r, and operate the 'ball-boxes when the hub is removed front` the axle. On the end of the spindle and screwed upon the thread s is a cap or jamnut D, which, by bearing against the cone a", maintains the ball-bearings in position. Tightening of the j ain-nut against the cone fr presses the ball-bearing surfaces against the balls, and loosening of the jam-nut has the opposite effect. It is desirable in practice that the jam-nut shall be so tightened against the cone 'r that the sleeve and boxes C' C2 shall be held against longitudinal play; but the jam-nut should not bear so'firmly against the cone-piece as to cause the balls to be bound in their bearings.
Fitting the threaded socket s2 in the end of the spindle is a set-screw Z, which may be adjusted to properly limit the distance to which the jam-nut D may be screwed upon the spindle. In the preferred construction I provide a locking-piece for the set-screw l, consisting of a spring-stem p, extending in the groove s2 and fastened therein at s4 and provided at the end of the spindle with a head p', having a segmental outer edge p2 and an inner engaging edge p2, adapted to fit against the head of the set-screw Z. The set-screw shown in the iigures, in the preferred'- construction, has a head of hexagonal form, and the engaging-edge p3 of the locking-piece is angular to fit a corner of the head of theV setscrew. In the base or outer innerpart of the IOO annular shoulder just large enough to receive the head or lock p'. When it is desired to change the adjustment of the ball-bearings, the jam-nut D may be removed from the spindle and the set-screw Z turned. In the turning of the screw the lock 29 yields against the resistance of the spring p. The screw is turned as described until it projects the desired distance beyond the end of the spindle to afford a stop for the inner end n of the jam-nut, which will permit the latter to be screwed so far upon the end of the spindle as to bear with desired force against the cone r.
W'hen the jam-nut is screwed upon the spindle, the lock p enters the recess n, and the annular shoulder formed thereby operates to hold the lock in unyielding engagement with the head of the set-screw to prevent turning of the latter.
In the modified construction shown in Fig. 12, I provide a lock consisting of a ring m, having an outer circumference approximating the circumference of the recess n and an angular inner circumferential edge just capable of receiving the head of the set-screw Z. The ring is provided at one edge with a stem m', fitting the recess s3 of the spindle. The head of the set-screw Z, employed when the ring m is used, may be hexagonal, as shown, so that it may be adjusted by stages of a one-sixth revolution and secured against rotation by means of the lock.
In the modified construction shown in Figs. 13, 14, and 15 no recess s3 is provided in the outer circumference of the spindle, but a recess s5is provided in one side of the threaded socket s2, the recess flaring at the end, as indicated in Fig. 13. The locking-piece consists of a spring-stem k, having a base-flange k and a set-screw engaging head or lock k2. The locking-piece is inserted into the threaded socket szto extend at its flange across the base of said socket and along its stem portion in the recess S5, the head 7a2 being beyond the end of the spindle. In this construction I prefer to employ a set-screw Z, having a serrated circumferential face, forming a ratchet, the inner or engaging face of the lock k2 being serrated to intermesh with the head of the setscrew. Vhen the jam-nut is removed the set-screw l may be turned, during which operation the locking-head 702 will yield against the resistance of the spring 7c. When the j am-nut is screwed upon the spindle, its recess n' will engage the locking-head 7a2 and hold it in engagement with the set-screw, as in the other constructions. The ends of the boxes C G2 revolve in annular grooves 1l i', located, respectively, in the flange A and jam-nut, and in the cones t r and adjacent surfaces of the boxes I provide coincident grooves for annular, preferably felt, washers h h. This construction renders the ball-races dust-proof without materially interfering with the antifricton nature of the bearings. I also provide in the flange A', about the spindle, a recushion f bears against an annular shoulder f2 on the cone r. The cushions j" g may be of leather or rubber, to render them slightly resilient. rlhe cushions operate to produce a sli ghtly-yielding engagement between the races and balls, and will neutralize shocks against the balls under the force of impacts due to the wheels traveling over a rough road. They will thus tend to prevent breaking of the balls. The cushions will also tend to prevent rattling of the parts and render the bearings noiseless. The cone 15 is prevented from turning by a pin el thereon, which passes through an opening in the cushion g/ into a socket e in the head A.
While I prefer to construct my improvements as shown and described, they may be modified in the matter of details without departing from the spirit of my invention as defined by the claims.
What I claim as new, and desire to secure by Letters Patent, is-
1. In a ball-bearing axle, the combination with a threaded spindle,hub thereon and hubretaining jam-nut screwed upon the spindle, said spindle having a threaded socket in its end, of a set-screw adjustable in the said threaded socket and at its end affording a stop for the jam-nut, and locking means on the spindle for the set-screw, substantially as described.
