Claims. 1
Many lubricators for diesel locomotive traction motor suspension bearings include a plurality of felt bodies on a resilient carrier or supporting member by which they are constantly urged against the journal. The felt bodies are carefully matched in each set, impregnated with oil, and sealed in a container for protection until just before installation. Service men, however, are not careful to maintain the sets matched, and frequently unmatched felts are installed, with theres'ult that a part or parts only of the felt surface may be applied to the journal and the lubrication is faulty.
The principal object of this invention is to overcome this fault; and, generally speaking, that is accomplished by mounting each felt body separately with freedom to move independently to adjust its position and properly apply its surface to the journal.
The invention provides improvements applicable to the traction motor lubricator illustrated Miller No. 2,540,829, February 6, 1951, Locomotive Cyclopedia, 1947, pp. 1020-1021, and others.

But these diagrammatic drawings and the corresponding description are used for the purpose of disclosure only.
The form shown in Figs. 1-11 includes a base it having parallel flanges l i, between which are assembled the individual carriers or supporting means i2, i3, and It, which are mounted on the base with individual freedom to rock and to resiliently yield to pressure toward the base.
The mounting includes a bar or a hinge pintle 5 spanning the flanges l l on the base and passing through hinge blocks l6 of rectangular cross section and individual to the carriers or support ing members.
The carriers or supporting members have elongated slots I? to receive the hinge blocks and to permit the carriers to move toward and away from the base by sliding over the blocks it within the limits allowed by the slots ll.
The carriers i2 and M are each provided with a downturned flange [8 at the inner side and a short flange 13 at the outer side formed by striking a part of the metal from the body of the carrier downwardly parallel to the flange 18.
The intermediate carrier I3 has downturned parallel flanges 29. The slots l I are in the flanges it, 85, and 2t, and aligned with the aligned hinge blocks it on the hinge pintle l5.
Each carrier or supporting member is resiliently urged away from the base III by two helical springs 2| having their ends surrounding spring guides or lugs 22, riveted respectively to the base and the carrier.
Each carrier supporting member has a projecting end portion 23 strengthened by a plate and provided with a hole 25 to receive a stud 26 on the corresponding felt holder 21, which is adapted to rest on the flat portion of the carrier, and is held there by the stud 26 and the springs 2|.
The holders 2'! are channel shaped pieces of metal with side flanges 29 adapted to grasp the felt bodies 30 and confine them laterally.
Each felt body has an arcuate or concavely rounded portion 3i projecting beyond the flanges 29 for contact with a journal to be lubricated, and also has a depending portion 32 projecting below the holder forming the wick, adapted to extend into the oil in the reservoir and raise it by capillary action to the curved surface 3 I.
Each holder 2? has an upwardly projecting portion 33 provided with a hole 34 to receive a hook by which the replaceable applicators can be removed from the carriers.
Since each carrier or supporting member can rotate independently on the pintle l5 and can move toward and away from the base independ ently of the other, they are allowed any movement necessary to fit the rounded surfaces 3| against the journal to be lubricated at all times. Variations in the thickness of the several applicators will not cause variation in the contact between the rounded surfaces and the journal.
The action of the springs 25 will hold the felts against the journal and at the same time hold the studs 28 in the holes 25, so that the applicators are maintained in proper position and on their respective carriers. However, when it is desired to remove an applicator, the springs 21 for an applicator may be compressed enough to enable the operator to remove the stud 25 from the hole 25 and lift the applicator out of place. correspondingly, new applicators can be readily inserted.
In the form shown in Figs. 12, 13, and 14, the base so has flanges 5i at the upper end, which receive a hinge pintle 52 for three sets of links or levers 53, each having one end pivoted on the hinge pintle 52 and the opposite upturned end pivoted on a pintle 55 to one of the carriers or supporting members 55, 55, and 57. The carriers have parallel flanges 58 receiving the pintles 54, to which they are riveted.
The outer flanges 58 of the carriers 55 and E? are formed by striking out a portion of the carrier, as indicated at E (Fig. 13)
Each carrier is urged away from the base by two helical springs 61 having their ends surrounding guides or studs 62 on the base and the carrier.
The hinge relation between the arms or levers -3 and the base and the carriers permits each of the carriers to have individual freedom to rock about the pintles 5d and to move toward and away from the base 50. Hence, they can adjust themselves to the journal substantially as disclosed in connection with the form shown in Figs. 1-11.
The applicators for the form shown in Figs. 1244 correspond to those shown in Figs. 1 and 2, and are made fast by the same sort of studs and holes.
