| It has also been proposed in order to prevent waste of oil by over-feeding such as described, to substitute for the soft felts a harder, porous material, from which the oil is not so rapidly removed. Such materials known to me as available for this purpose and which have a cellular structure of sufficient fineness to feed oil at the proper rate, are objectionable in that they do not have sufficient oil-carrying capacity to provide lubrication over a long period, and must be frequently re-oiled. 10 One of the objects of my invention is to provide a bearing with means which shall automatically distribute oil or other suitable lubricant to the load members at a rate to adequately lubricate the parts without waste, and which shall be fed by members which have sufficient oil-carrying capacity to lubricate the bearing for a long period. Another object of the invention is to provide a device of the character designated in which any oil which may be thrown from the load members by centrifugal force during the rotation of the bearing will be retained in the bearing. 20 Other objects of the invention will appear from the following description, taken in connection with the drawings, which form a part of this specification, and in which: Fig. 1 is a view, partially in side elevation and partially in section substantially on the line 1-1 of Fig. 2, showing a ball bearing of the thrust transmitting type constructed in accordance with the invention; Fig. 2 is a view in section, taken substantially on the line 2-2 of Fig. 1; Fig. 3 is an enlarged detail sectional view through the ball and retainer assembly of the bearing shown in Figs. 1 and 2; 30 Fig. 4 is a view similar in mature to Fig. 3, showing the application of the invention to a bearing of the roller type, and Fig. 5 is a detailed sectional view illustrating a modified - 3 - | ||
