e it known that 1, AUGUST RIEBE, en:

, gineer, a subject of the King of Prussia, German Emperor, residing in Berlin, N. W.,

Kaiserin-Augusta-Alle 30, in the Kingdom of.

'Prussia, Germany, have invented certain new and useful Improvements in Ball-BearlIlgS, of which the following is a full, clear and exact description.

provided with abutmentplates connecte by sprin s these springs p are usually in contact with't eouteror inner ring over the surface of which they slide. Conse uently there is always the risk that said p ates may be forced out between the.

balls, which press a ainst them, and that the spiral springs may e turned over, with the result'that as they are no longer controlled by the rounded ball-race they are liable to fall out, thereby naturally endangering the continued regular runmng of the ball-bearmgs. Such inconveniences are rendered impossible in the present new construction.

In the accompanying drawingawhich illus- I trate a ball-bearing constructe according to the presentinventlon, Figure 1.is a front elevationof a part of the cage and intermediate distance-pieces drawn to a large scale. Fig. 2 is a top view of a single intermediate distancepiece. Fig. 3 illustrates a complete bearing,

partly insection, constructed according to the present invention. Fig. 4 tion through a distance-piece.

The se arateintermediate distanceieces include oxes consistin of two' U-s aped bent plates f and e, sliding b their limbs telescopically one within the ot er, andwithin the box thus formed is-a spiral spring it, provided with a lubricating or felt insertion or cove t; -'Ilhe sliding connection between is a cross-sec the plates insures their parallelism and a normal pressure on the sprin ,in all positions of the plates. The expan ing' tendency imparted to the plates e and f by the spring h is, as shown in the draw' 's, limited by the stalys or straps l and k of t e cage-ring c.

notches in the plates e and f in suc manner that the expansive movement imparted to the latter by the spring 72. is limited by the shoulders or edges of said grooves or notches, and the contractile movement of said plates is also limited by the arrangement that the parts moving relativel out di 2',orat t e inner edge, as shown in ig. 3.

In order to protect the parts of the cage ends of the two-arms or limbs of the plate e when the plates are pressed together come against the other plate It would of course also be possible tolumt said movements-by forming the grooves or notches in the plates e and f of suitable w1dth with relation to the stays or straps land 7c. The abutment-plates e and f are thus no longer mechanically connected with the spring h;

butthey are supported and guided by the stays or straps 7c and Z of the cage-ring c. The

springs hdo not come into contact with the ball-race, .and thus are. not connected with the turning over or fal in out of the springs is thus rendered absolute y impossible.

Inasmuch as theseparate intermediate boxes are mounted on the same ring, the ea c forms a compact whole, which can be eas y takenoutand the boxes withdrawn from between the balls after removal of the claspring g. This arrangement has the advantage of overcoming the diificulty of dismountlng the intermediate boxes separately, which operation was 'very troublesome and caused to said springs, and

great loss of time, as the removal of the ring g, (which by its natural spring-like action,

aided during the running of the shaft, axle, or

the like by centrifugal force, takes firmly underthe hook-shaped extensions of the stays or stra s l of the cage,) can be effected Withcult and without the aid of any instrument. he straps Zmay be either at the outer ed eof the cage, as showninFi s. 1 and above described from 'wear-and tear through against the inner or outer ring,

rubbing, plates are provided, which only serve the purpose of bearing-surfaces, so that any slidm of the whole ca e construction can only ta e' lace between t ese plates and the rings,

and ence only the (plates (1 are ex osed to wear and. tear. Sai plates d ma e made of material which is only liable to e slightly afiected by the wear and tear under the strain to which they are subjected. It is, however,

. possible by using tempered steelplates to rehe stays or straps Z and 7c lie in ooves or three the wear and'tear to what is for all prac-' tical purposes a negligible quantity. It will be understood that cages constructed accordi to the "present invention may with certam modifications be em loyed in' connection with other bearings wit out departing from the principle thereof.

What I claim as my invention, and desire to secure liylietters Patent, ie-

1. In aball beiiring, a distance-piece between adj aeent balls comprising a spring, end plates inelosing said spring, and means for holding said end plates parallel to each other While permitting movement thereof toward and from each other.

21 In a lull-bearing, :i cage-ring, a distonee-pieee lietweer adjacent balls and supported by said. ring, and a elzisp-ring connect- ((l to said angering. l

3. ln :1 lull-hearing, o distance-piece having end plates, means for vonneeting snirl plates so that they can slide toward and from em-li other, nnll means for holding said piece in position between the halls.

l. in 2L hell-pouring, ll, (llstilll('lI-l((0 having (lHl plates, and means for holding; soiil piei-e in position between iliebnlls,sni i means permitting sni l plates to move toward and ll'ulll (ZH'lI other.

5. ln :1 l nll-l enring, o (listnnee-pieve how ing end plates, means for holding Sillil pieee in position between the ballsv sniil means permilling szliil plates to move toward and from (2l(.l1()ill(1,itll(l means forliniitinp snili 'inoveinents.

(i. in n lmlll e:1ring, :1 (listnnce-pieee havin; end. plates, comprising two U-shoped members adapted to slide relatively to each other, a spring interposed between suclnnemhers, and means for limitiin the movements of said members. i

7. In a ball-bearing, a distance-piece hiv ing relatively sliding end plates, and a cagering having portions interposed between such plates and adopted to support the some.

8. In :1- inth-bearing, a distance piece having relatively sliding end plates, at cage-ring; having portions interposed between sueh plates, and adopted to support the some, and a plate a between such distance-piece and said ring.

9. in at hall-hearing, a distance-piece (umprising two plates nndf, having portions sliilingnpon each ()ll1-l',$l1(li portions having depressions on their upper and lower sides, and n enge ring inning portions /r and Z entering sin-l1 depressions for supporting SlH'll piere and limiting the movements of such plates.

in witness whereof l have hereunto signed my 1121-1119 in the presence of two subscribing witnesses.
