ROLLER-BEARING.

SPEGIFIGATION forming part of Letters Patent No. 760,508, dated May 24, 1904. Application filed November 16, 1901. Serial No. 82,592. (No model.)

To all whom it may concern.-

Be it known that we. WALTER S. WOOD, residing in the city of Kalamazoo, and SAMUEL DOUGLASS, residing in the township of Texas,

5 in the county of Kalamazoo and State of Michigan, citizens of the United States, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification.

I This invention relates to improvements in roller-bearings; and the objects are, first, to

provide in a roller-bearing improved means for maintaining the bearing-rollers separated from each other around the axle or journal; second, to preserve parallel alinement of said rollers with the axle or journal; third, to pro vide means whereby the bearing-rollers may be spaced or separated evenly or unevenly, as may be desired, in arranging said rollers around the journal; fourth, to maintain and guide the bearing-rollers around the axle or journal in such a manner that they will operate equally as well with a half boxing or casing as with a full or divided boxing or casing; 5 fifth, to retain the bearing-rollers intheir assembled position within a hub or boxing when said hub or boxing is removed from the axle or journal; sixth, to assemble and maintain the bearing-rollers in proper position inde- 3 pendent of either journal or boxing without the use of the usual cage employed for such purpose; seventh, to preserve a perfect rolling contact between all moving parts to reduce friction to a minimum; eighth, to provide improved retaining-rings to embrace and protect opposite ends of the beai'ingrollers, said rings to always maintain the same relative position with the axle or journal whether rigidly secured or loosely mounted thereon. 4 Other objects will more definitely appear in the detailed description to follow.

We accomplish these objects of our invention by the devices and means described in,

this specification and definitely pointed out 4 5 in the claims.

Structures embodying the features of our invention are clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a longitudinal sectional eleva- 5 tion through a vehicle-wheel hub of the bicycle pattern, taken 011 a line corresponding to line 1 1 of Figs. 2 and 3. Fig. 2 is an end elevation looking from the left of Fig. 1. Fig.

Fig. 6isa transverse sectional elevation corresponding to Fig. 3 with the hub or boxing removed and illustrates some features to be referred to hereinafter. 5 Fig. 7 is a longitudinal sectional elevation through one end of a journal-bearing, taken on a line corresponding to line 4 4 of Fig. 5, illustrating some modifications which will be more particularly referred to hereinafter. 7 Fig. 8 is an assembled perspective view of the bearing-rollers and retaining-rings removed from the journal and boxing, with a portion of one of the retaining-rings broken away to show the relative position of parts. Fig. 9 is a transverse sectional elevation taken on line 9 9 of Fig. 10, and Fig. 10 is a longitudinal sectional elevation taken on line 10 10 of Fig. 9. Said figures illustrate some modifications which will be more particularly referred to hereinafter. Fig. 11 is a transverse sectional elevation through a car-axle bearing and illustrates our invention in use with only a halfboxing. Fig. 12 is a longitudinal sectional elevation illustrating some modifications of 5 parts which will receive further mention hereinafter.

In the drawings the sectional views are taken looking in. the direction of the little arrows at the ends of the section-lines, and simi- 9o lar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is a vehicle-axle, of which A is the spindle or journal portion, provided with a collar A at its inner end and a removable collar H at its outer end.

B is a boxing which as here shown isin the form of a vehicle-wheel hub of the bicycle pattern, provided with the annular flanges B B, to which the wire spokes are attached in the usual way.

B is an annular oil-chamber for the reception of lubricant.

A series of bearing-rollers C of even size from end to end are arranged between the journal A and boxing B. These bearingrollers have peripheral grooves C. C near their opposite ends and are also provided with small pintles or pins C C", projecting centrally from each of their ends.

At opposite ends of the bearing-rollers C and within suitable recesses in the ends of the boxing are loosely mounted retainingrings to hold and guide said bearing-rollers in their proper relative position around the axle or journal. Said rings are formed, preferably, of two parts D and D, which are screwthreaded together and firmly locked by opposing faces contacting. An annular groove a is formed between the parts, which corresponds in size and shape to those in the ends of the bearing-rollers. To hold the said bearing-rollers separated from each other around the journal, we make use of short intermediate spacing rollers or bodies E. Said spacingrollers are held between the bearing-rollers at their opposite ends by the retaining-rings D D and are provided with collars E, adapted to engage grooves C of the bearing-rollers and annular grooves a of the retaining-rings to prevent longitudinal displacement of the bearing-rollers.

The part D of the retaining-rings is provided with an inwardly-projecting rim D,

adapted'to embrace the pins C on the ends of the bearing-rollers 1, to prevent displacement of said bearing-rollers when removed from the journal with the boxing or independently when assembled, as shown in Fig.

8. Rim D is not intended to contact withv the pins C when the bearing-rollers are in position around the journal, but when removed from said journal the pins C come in contact with the rim D, and are thus prevented from displacement. It is obvious that when the bearing-rollers, spacing-rollers, and retaining-rings are thus assembled (see Fig. 8) they are securely held together without the use of the usual cage employed for this purpose and will admit of free handling without the liability of the parts becoming separated. In fact, they can become separated only by removing the retaining-rings. This is an important feature of our invention.

It is obvious that the surfaces of the bearing-rollers and the spacing-rollers will travel at the same rate of speed or there will be slipping between their surfaces. Therefore the internal track of the retaining-rings upon which the spacing-rollers travel should be practically of the same diameter as the boxing upon which the bearing-rollers travel.

Of course the spacing-rollers must engage the outer periphery or surface of the bearing-rollers or a surface of equal diameter which shall be attached and form a part of said bearing-rollers. Thus it will be apparent that when the boxing is revolved the retaining-rings will remain idle with the journal, and when said journal revolves said rings will revolve with it at the same rate of speed. Therefore the retaining-rings and journal will always be in the same relative position with each other, and said retaining-rings may be secured rigidly to the journal, as shown in Fig. 7, in which the part D of the retainingrings is made integral with a set-collar M and secured to the journal I by means of a setscrew in the ordinary way. The part D of the retaining-rings is here shown adjustable on part D for the purpose of adjusting the size of the annular groove (0 and is locked in position by the locking-ring a.

On the right half of Fig. 3 is indicated by little arrows the direction in which rollers C and E will revolve when the boxing is revolved in the direction of the arrow on the outside, and on the left half of same figure is indicated in same manner the direction in which the same rollers will revolve when the journal is revolved in the direction of the arrow thereon. Therefore it will be seen that the retaining-rings must revolve when the journal revolves'and remain idle when said journal is idle. I

Itis obvious that our invention permits of the use of the same size of bearing-rollers with different sizes of journals and corresponding sizes of retaining-rings and boxing, a feature of importance and practical utility in the manufacture of this class of journal bearings. Fig. 6 illustrates this feature, in which is shown a journal a trifle larger (in this case one-sixteenth of an inch) than the journal in Fig. 3. The retaining-ring is also enlarged to correspond to the enlargement of the journal. The boxing is removed from this figure, but'of course would also be enlarged to correspond to the enlarged journal. The bearingrollers are precisely the same size and the same number as shown in Fig. 3. It is therefore evident that the bearing-rollers must be spaced differently than in Fig. 3, owing to the increased periphery of the journal. We therefore introduce two larger-size spacing-rollers E, using the balance of the spacing-rollers E of the same size as in Fig. 3, which completes the train of rollers and maintains absolute rolling contact between all the parts. As the spacing-rollers act as intermediates between the bearing-rollers and retaining-rings they may be all one size or of different sizes. Of course the same size spacing-roller must be used at the opposite ends of the same two adjacent bearing-rollers in order that their parallel alinement be maintained. Thus it will be seen that the bearing-rollers may be spaced evenly or unevenly around the journal by introducing different sizes of spacing-rollers in the same train without in the least impairing the perfect working of all parts. It will be apparent that for a certain size journal, either larger or smaller than that shown in Fig.- 3, it would be only necessary to introduce an extra bearing-roller in the case of the larger journal or take out a bearing-roller in the case of the smaller journal, when the bearing-rollers would be all equally spaced, as shown in Fig. 3. Of course each size of journal will require its corresponding size of boxing and retaining-rings. It is only the intermediate sizes of journals which are between the two sizes that req uire a certain number of full-size bearing and spacing rollers to fill the train around the journal that the varying sizes of spacing rollers are required-41. a, it is to make up for the fractional part of a bearing-roller which it would require to fill the annular space around a certain size journal that we introduce the varying sizes of spacing-rollers to complete the train instead of changing the size of all the bearing-rollers and spacing-rollers, which would greatly increase the cost of manufacture. We desire also to state that with the spacing-rollers held in close contact with the bearing-rollers by the retaining-rings practical parallelism of the bearing-rollers with the journal is maintained and also prevents the rubbing of the surfaces of the bearing-rollers, thereby reducing the friction of this class of journal-bearings to a minimum.

Figs. 9 and 10 show a modification in which balls N are used in place of the spacing-rollers E. The parts D D of the retaining-rings are adjustable and are. locked in position by the locking-ring a. This structure admits of close adjustment and also of spacing the bearing-rollers evenly or unevenly the same as with the spacing-rollers. The adjustable retaining-rings may be used with the spacingrollers also.

Fig. 12 shows another modification of certain parts in which the pins 0 are removed from the ends of the bearing-rollers and the inwardly-projecting rim D from the retainingrings. G' refers to the bearing-rollers with the pins removed and D to that part of the retaining-ring with the rim removed. Of course this structure will only prevent longitudinal displacement of the bearing-rollers when around the journal and would not retain them in position when removed therefrom.

Referring again to Fig. 1, collar A at the inner end of the spindle orjournal is provided with a suitable ball-race F to retain antifriction-ballsR. At the outer end of the spindle or journal is a removable collar H, provided with the nut portion H, preferably screw-threaded to the spindle or journal for convenience in removing. Said collar is also provided with a ball-race F for retaining balls B. These collars are necessary to maintain the relative position of the boxing and journal and also to prevent longitudinal displace ment of the bearing-rollers and retainingrings. At opposite ends of the boxing is inserted rings G G, against which balls R bear. Back of these rings are the rings G G, of suitable resilient material to form a cushion to relieve the impact of end thrust upon the balls and prevent crushing. Also the resiliency of the cushion-rings tends to take up wear and lost motion between parts and prevent rattling. A ring of felt or similar material a is placed in the outer end of the boxing toprevent the ingress of dirt at that point, and also a similar ring 6 for the same purpose is placed at the opposite end of the boxing, as shown in Fig. 1, which makes the hearing practically dust-proof.

It is apparent that balls R in collars A and H could be dispensed with, as also could the cushion-rings G in the ends of the boxing and said collars still have the functions of re taining the relative position of the boxing, journal, and bearing-rollers, and retaining rings.

Referring to Figs. 4: and 5, which illustrate some modifications of our invention, J is a pillow block or base of a journal box, and J" the cap therefor,sec1u'ed to the base in the ordinary way. 1 is a portion of a journal or shaft which corresponds to the journal A in Fig. 1. At the right of Fig. 4: we show the part 1) of the retaining-rings integral with a collar K and provided with the ball race F", corresponding to the ball-race F in Fig. 1, in which is inserted balls R to bear against the ends of the boxing. Collar K is loosely mounted on the journal and could be made separate from the part of the retaining ring D. A set-collar L is secured to the journal in the usual way and is provided with a cusl1ion ring G, corresponding to the cushion-ring G in Fig. 1. ,It is obvious that this construc tion and arrangement of parts can be used at either end of the ournal. At the left of Fig.

4 we show an ordinary set collar secured to the journal, which will perform the functions of retaining the relative positions of the boxing, journal,and retaining-rings and bearing rollers. Itis also obvious that this set-collar may be used at either end. of the journal.

It will be observed by reference to Figs. 1 and 4:, that the bearingrollers and their retaining-rings are allowed a certain amount of longitudinal movement, which is limited by the collars A and H in Fig.1 and L L in Fig. 41. From the fact that the retaining-rings are always in the same relative position with the journal '11. 6., always move with it-it is obvious that contacting of the retaining-rings with the collars secured to the journal will not impede the perfect working and movement of the said rings or the bearing-rollers. However, said retaining-rings should not be allowed to come in contact with the shoulders T of the boxing, as shown in Figs. 1 and 4, as this would cause friction and impair the free working of the retaining-rings and bearingrollers.

Fig. 11 illustrates our invention applied to a car-axle journal, in which I is the journal portion of the axle, P is the bearing-boxing, and P the usual half-bushing on top of the journal. It is apparent that the retainingrings will support and guide the bearing-rollers around the under side of the journal without the use of a boxing at this point.

It is also obvious that our improved rollerbearing is perfectly adapted to be used with a separable or split boxing, as the retainingrings hold the bearing-rollers in contact with the journal and allow them to pass any separation in the boxing without a hitch 01' jar; also, the boxing may be tightened about the bearing-rollers the same as an ordinary journal-box. (See Fig. 5.)

We desire to state that our improved rollerbearing is adapted for use in any place where such bearings can be successfully used.

We also desire to state that while we have shown our improved bearing in its approved form we are aware that it may be greatly varied without departing from the essential features of our invention.
