BALL-BEARING.

Specification of Letters Patent.

Patented Nov. 17, 1914.

(Jontinuation of application Serial )lo. 655,652, filed October 18, 1897. This application filed April 6, 1910. v, Serial No. 553,897.

My invention relates to ball holding de vices, andparticularly to that class o't'ball bearings wherein a holder is used, havinga series of ball bearing points to retain the balls, the latter projecting'beyond'the device, in the inner and outer, and in .the upper directions with respect thereto, and it has for its object the provision of an organization of the class described, simple in construction, inexpensive to manufacture, and which operates in a smooth, easy and noiseless manner in practical use.

To attain the desired end, this, my invention, consists in the construction, arrangement and operation of the parts herein set forth.

In the drawings which accompany and form apart of this specification, Figure 1 my ball retaining devices; and Figs. 9 and.

10 are respectively views of blanks of which the retaining devices shown in Figs. 2 and 6 are made.

Like letters of reference indicate like parts in all the views.

I have found it desirable to devise a ball bearing of simp e construction, and one that will be reliable and efiicient, as well as noise less, in practical use, in which the balls are held in their normal positions by means of a retaining device, and I have, therefore, constructed according to my invention, an organization of the kind set forth, embodyin}; the preferred construction of parts and their mutual relationship, combination, arrangement and organization in a composite body or structure, as hereinafter described.

Referring particularly to the drawings. A

denotes y ball holding device located in the chamber formed by the inner flanges of) y i the hub A-',-and the cones of'the axle A,

inner and outer-bearing points In the embodi ment illustrated in these figures the edges cities the walls of the recesses A formed between the upper portions A of the ring, are preferably parallel with each other, and the same extend upward above the center line of I the balls B; the side walls a of the'same,

these intermediate portions in thisinstance e rtending radially or transversely of tliefj' rlng, in'connection with ,the bottom portion of said ring, constituting the recesses Af" which walls a are preferably inclined to-' ward the balls in order that the upper por-' tions of each recess will be somewhat smaller than the lower part thereof. My bearing points or detents consist, in this instance, of one or morevertical prongs, as a in Fig. 3, located in the inner and outer poi,- tions of the recess A", or lateral prongsfas' o in Fig. 4, located along the inner and? outer edges of the side inclined portions of my ring A. If preferred,-however, the. parts of my ring, forming the lower portions of f Said y be of circular f rm, 5 A shown in Fig. 5, or they may be rec tangulari as Flgs- 6 and constitutin g the recesses A, and to the upper portions, as A, of my ring, as in Figs. 6 and 7, may

be secured, as by pins a, supplementary platesA, provided with projecting retain ing portions or pointsa, formed by. the.

same being laterally recessed or 'concaved,

the said top portions being wider at their outer edge than at the inner edge thereof.

It will be apparent from a consideration of the several forms of my invention illustrated and described that it comprises a ring-shaped device having a base portion that serves as a support upon which. rests the series of balls, that from this base portion of the retainer there are bent up a series of members designated a. in the drawings. and termed herein side walls, as they serve to separate from each other the recesses in which are confined the individual. balls. though these members may also with propriety be termed standards or flaps, and

- stantially parallel with the base portionsof the retainer and in angular relation to the side walls (otherwise termed standards or flaps) that rise therefrom, so that: they extend outward from. the sidewalls more or less over. the recessesjo'r the balls, the latter being retainedinthe-holder whenit is'removed from the ball raceor bearing.

The side wallsa stotherwise termed standardsor flaps) that risefrom the base may be erpendicular thereto, as indicated-in F ig; g or inclined thereto, as-representedin Figs. 3, 4 and 5swhilethetop retainersscarried by the saidside walls maybe-integralthere;

with, 'as indieatedinz'Figs, 4, 5,, Band- .7-, m

of a compound two-part nature, including plates secured who the top-upor'tions .asindicated in Figsafi and .7 a-Eusthep, the edges of the top retainers that bound-the recesses in which are. situated-theg-balls -meyqbe straight and substantially parallel with each I other, as indicated in Fig. 4, or they may be of a substantially concave contour, as indi cated in Fig. 6, this latter construction for some purposes being the one which I prefer. In both constructions, indicated respectively in Figs. 2 and 6, the'top retainers extend outwardly, that is, they are radially disposed (each considered as a whole extending from a position substantially over the inner edge of the ring to a position substantially over the outer edge thereof, and they are each laterally enlarged, that is, each portion or extension is larger or wider at its outer portion than at its inner portion. This construction results in the production of a topretaining member for the balls having sharp corners or pointed ends. When these top retainers are constructed as-indicated in Fig. 6, that is, with the-edges that bound the 'ball recesses made concave, the pointed edges thereof are emphasized, as indicated ata in Fig, 3. The advantages incident to this latter construction arise from the fact that by 'concaving the opposite edges of the top retaining extensions the balls are allowed to project upward, that is, away from the base support, and out of their recesses, to a greater extent than where .the opposite edges are straight, as indicated in Fig. 2. When the holder is formed as indicated in Figs. .8 and 9, the parts of the top retainers designated A extend outward from the side walls (otherwise termed standards'or flaps), as clearly indicated in Fig. 7, so as to lie over and retain the balls.

It is manifest that various omissions of some -particulars could be made without materially aifecting theessential-features of yond the same .in the inner and ,outer'and,

in the upper directions, The ballsare thus securely held in place, and by means of the construction. shown, are allowed to move quite a long distance radially, and they are thus enabled to adjust themselves, in case of any. wearing of thebearing taking place, the side bearing points, "asstated, preventing the balls from rolling'ou't oftheir sockets, in either-asvertical, radial or lateral direction, which balls may be readily snapped in and out of the-retainer,.at will.

Obviously, my ball retaining device-may be advantageously employed in many kinds of hearings .or sockets, and I do not therefore wish to limit myself to the use of my device in connection with ball bearings of the kind shown alone. I

As it'is evident that many changes in the construction and relative arrangement of parts might .be resorted to ,without departing from the spirit and scope of my invention, I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that such changes and eguivalents may be substituted therefor, and t at What I claim as my invention, is z 1. An annular ball-holding device COIDr;

prising supporting means for balls, intermediate portions projecting upwardly from the said supporting means in approximately radial directions, and top retainersjoining the supporting means and projecting some what over a part of the surfaces of the balls.

prising a base constructed and arranged to support the balls, top portions extending substantially parallel to the base, inter-. the base andtop.

2. An annular ball-holding device comthe intermediate portions and overhanging F ries of upwardly extending parts, and also concaved.

5. A ball-retaining device for ball hearings consisting of a ring comprising a se ries of upwardly extending parts, and also a series of practically horizontally-positioned parts superimposed over the ring, the said practically horizontal parts being wider at their outer edge than at the inner edge thereof, and having at the outer and inner edges of the same points projecting into the ball holding recesses.

6. A ball-retaining device for ball bean ings consisting of a ring comprising a series of upwardly extending parts, and also a series of practically horizontally-positioned parts superimposed over the ring, the

said practically horizontal parts being Wider at their outer edge than at the inner edge thereof, and having the side edges of the same concaved, and having at the outer and inner edges of the same points projecting into the ball holding recews.

T. A ball-retaining device for ball bear ings consisting of a ring comprising a series of upwardly' extending parts, and also a series of practically horizontally-posh tioned parts superimposed over the ring, the said practically horizontal parts having the side edges of the same concaved.

In testimony of the foregoing specification. I do hereby sign the same in the city of New York, county and State of New York, this second day of March, 1910.
