This shapes pended. the core into a cylinder having circular stiffll In the accompanying drawings: ening springs M. u

Superimposed upon the core prior to the shaping thereof is an external pad or flexible lubricant applicator ll of one or more pieces of felt or the like, the same being stitched diagonally at intervals as at It to give strength and.

required stiffness thereto. It is advisable to have the outerply of felt of this pad Ii of good quality as the same takes the wear, if any, while 'the device is in use, the inner ply or piles of felt being of inferior quality as the same serves as an oil reservoir in the use of the lubricator. The pad I! is stitched to the core marginally thereof by stitches I1, also at spaced intervals as at If. thus these becoming a unit.

Arranged within the core II is a mat l8 preferably made of freely flexible relatively thick felt and functions as an additional oil reservoir.

The core has fastened interiorly thereof at opposite sides and at spaced intervals the spiderlike anchors or fasteners including the chain lengths l9 and a center ring 2. common to and loosely connected with said lengths IS, the chain lengths being fastened at II in any suitable manner to the core. The mat Ii is formed with slots 22 providing clearances for the spider-like anchors or fasteners, the latter functioning to prevent the lubricator from rolling or travelling with the journal B as they maintain the lubricator somewhat dished or non-circular in cross-section beneath the said journal B as is clearly shown in Figures 1, 2 and 3 of the drawings.

In Figures 8, 9 and 10 there is shown a slight modification of the invention, wherein the core 23 and pad 2| which are alike to these parts hereinbefore described in their make-up, are provided with the end lips 25 and this lubricator is designed to be fitted within a box 28 for a journal 21 so that the outermost lips 28 of both the core and pad will contact with the hub II of a wheel 29, thus lubricating not only the Journal 21 but also the hub 28 of the wheel.

It should be apparent that the parts I! and 2. of the spider-like anchors will function as antirolling devices to prevent the lubricator from roling or traveling with the journal, especially during the colder months of the year when lubricant is chilled.

The design and construction of the lubricator enables a saving of labor expense in the inspection of journal wedges and brasses and replacing of the same as it will not be necessary to remove the lubricator from the journal box when doing work of this nature.

An important item for the invention of this type is the reduced cost in the manufacture of the iubricator, as it is inherently strong and in the making requires no special tools nor is it necessary for the use of tools in the application and removal of such device.

The device as shown in Figures 1 to 7 of the drawings has its core ll provided'wlth transverse straps 3i forming hand loops 3i, these facilitating the removal of the device when within the journal box as should be apparent.

What is claimed is: 1. A lubricator of the character described com prising a cylindrical flexible core having resilient inserts spaced from each other and circumferentially of the core, a pad carried by the core, a mat held within the core, and anchoring spiders connected interiorly of the core and passed through the mat.

.mat held within the core, anchoring spidersconnected interiorly of the core and passed through the mat, and lips extending from opposite ends of the core and pad, the said core being formed from fabric.

4. A lubricator of the character described comprising a cylindrical flexible core having resilient inserts spaced from each other and circumferentially of the core, a pad carried by the core, a mat held within the core, anchoring spiders connected interiorly of the core and passed through the mat, and lips extending from opposite ends of the core and pad, the said core being formed from fabric, the said pad and mat being formed from felt.

5. A lubricator of the character described comprising a hollow flexible lubricant applicator of material suitable for conveying lubricant to and wiping it onto a moving surface and means within the applicator, extending across the space therein and connected with the applicator at opposite sides of said space for preventing rotation thereof due to movement of said surface.

6. A lubricator of the character described comprising a hollow flexible lubricant applicator for conveying lubricant to and wiping it onto a moving surface and meanscomprising crossed chains connecting generally opposed portions of the applicator and extending across the space therein for maintaining the applicator non-circular in cross section and to prevent rotation thereof due to movement of said surface.

7. A lubricator of the character described comprising a peripherally closed hollow flexible lubricant applicator of material suitable for conveying lubricant to and wiping it onto a moving surface in contact with the applicator and which surface tends upon movement to cause the applicator to rotate, and means connected with the applicator at opposed portions thereof and extending across the space therewithin and maintaining such opposed portions against separation to such an extent of separation as would permit the applicator to rotate due to movement of said surface.

8. A lubricator of the character described comprising a peripherally closed hollow flexible lubricant applicator of material suitable for conveying lubricant to and wiping it onto a moving surface in contact with the applicator and which surface tends upon movement to cause the applicator to rotate, and flexible tension means connected with the applicator at opposed portions thereof and extending across the space therewithin and maintaining such opposed portions against separation to such an extent of separation as would permit the applicator to rotate due to movement of said surface.
