Thisinvention relates to that kindoft railway aXle lubricating device in which an ab'- sorbent pad connected to or 'formed integral With-capillaryy feeders dipping into the oilV in the axle-box is supported in contact with' fthe journal by means'of a spring frame com`- c prising a cradleya ltransverse bearer'strip central to the cradle, straight longitudinal side members connected togetherby trans- Yverse strips, and double elliptical side members attached to the'longit-udinal side inem'-,

bersrandto the ends of the transverse bearer strip.

In employing this type of lubricating fide-A vice it has beenfound that' the cradle member had va tendency torbecome wedged between the ends-ofthe double elliptical side journal and the other 4end'is'leict iinlubri` cated. Now the object of the present invention is to modify or improve the construc-` fr panying drawings/wherein cradle depressed at `one end.

According ,to the invention the double elfV liptical sidermembers ot tlie'spring frame are connected together by transverse members adapted to prevent vthe'vvedging otlthe.4

cradle between Vthe ends ofathe double elliptical side members when the said cra'dl'efis depressed thereon. l l i i Q f i In order that the invention may be clearA ly understood and readily carriedy into effect, the same Will now be Amore fully described with reference to and-by aidofthe accom- Figure l is asileelevation of kmy improved aXle lubricating device. v, lFigure 2 is a plan view of Figure l, but With a portion ofthe absorbent pad omitted for the sake of clearness. i
