To aZZ whom it may concern Be it known that I, AUeUsT RIEBE, engineer, a subject of the King of Prussia, German. Emperor, residing in Berlin, N. W., Huttenstrasse 34-35, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in or Connected with Partition Devices for Ball-Bearings, of which which'the following is a full, clear, and exact description.

The s ring-acting-intermediate pieces between tffe balls which have come into such general use in connection with ball-bearings ave often excessive demands made upon them in conse uence of the accelerative power imparted to t e balls and the compression togetherof the latter thereby caused, the resu t of which is the increased wear and tear and ultimate destruction of the springs, as well as of the end plates, which in the case of the partition device selected as an illustration of the present invention form a closure for the springs at both ends, thus eriling the precise action of the bearing. order to overcome this evil and for the purpose of regulating the admissible compressibility of the spring insertions or partition devices, a laterally-expansible sleeve d is, according to thepresent invention,.fitted onto, so as to more or less embrace, the springs of the said insertions, the sleeve in question being open laterally with aspring action in a tangential direction and st ff in an axial direction, whereby compression, beyond a certain point, of the spring parts of the partition devices brought into action can be avoided. For instance, in the device selected for illustration the balls," even when the partition deviceis fully compressed, are able'to issue. from their recesses in the end plates. In the latter 1 case the compressibility of the spring-acting partition devlce thatis, the length of sleeve dmust be so regulated that the play allowed V for spring action shall be less than thedepth of the recesses e in the end plates 6, becauseif the play should exceed the depth ofjthe' recesses e in the end plates theballs would, in the case of an overcompressed intermediate piece, of themselves come out of their respective recesses, and so considerably interfere h' rking 1 In the accompanying drawings the invention is illustrated, by way of example, in contion device or intermediate piece consisting of,

one of the end plates in elevation. Fig. 2 is a is an end elevation of another style of sleeve; Fig. 4 is a cross-section showing a third style of sleeve. Fig. 5 is a side elevation with the rings partly broken away, illustrating the parts assembled in a bearing.

The device shown in Fig. 3 is desi ned for tions require the spring 0 to be completely encases the latter must, as shown, be made in two parts d and d overlapping each other and supporting over their entire end surfaces the two end plates 1) when the spring acting partition devices are in a compressed osition.

a modification 0- the device hereinbefore described. As hereinbefore mentioned, the sleeve d must in order to be pressed over the size approximating the diameter .of said spring; but, owing to this notch or sl1t;m

no continuous support for the end plates. In fact, the plates are deprived of support in the part where the slit or openin comes, so that in certain positions of the evice the end opposite corners of the sleeve d forming the t1 ting or tipping axis. This risk of tipping is of course mereased by the point of contact of the ball not being in the center of theend plate,- but situated eccentricallywith relatlon to the same. r

, When the-position'of the partition device .is 'suchthatthe point of contact of the ball A reaches itsnearest position to the tilting axis, this point of contact may under given conditions be soclose to the tipping or tilting edge that the sleeve (Z is not able at this polnt to the utility o the sleeve (2 itself is-also renthis d' culty, it has been found that the best construction for the sleeves is that illustrated in Fig. 4, in which the sleeve d, in contrast to the previous form of construction, is extend- 1231611 a way-as to orm two extensions (Z, "W

In order to overcome ch do not inany way interral spring 0, but entirely prevent the tipping or tilting of the end plates under the conditions described above. It is obvious that with this form of construction there can be no tipping or tilting of the end 1plates even if the point of contact of the bal approaches unduly thetipping-line a; 'y, as the vertical extensions d then provide the necessary suport. I What I claim as my invention, and desire to secure by Letters Patent, is

1. In compressible partition devices for 4 ballbearings, means for limiting the com- Withdrawn laterally over said spring, the 20 length of said sleeve being such as to limit the movement of the end plates toward each other so as to prevent such compression as would permit the-device from escaping from between the rings. a

3. In partition devices for ball-bearings a spring, a pair of end plates, and a sleeve (Z adapted to be introduced laterally over the spring and having extensions (1 to providebearings for the end plates beyond the openin in the sleeve.

in witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
