DISK-OILER ATTACHMENT FOR CAR-AXLES.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed January 13, 1905. Serial No. 240,924.

To (all whom it may concern:

Be it known that I, LAVALETTE L. LOGAN, a citizen of the United States, residing at Bobertsdale, in the county of Huntingdon and State of Pennsylvania, have invented new and useful Improvements in Disk-Oiler Attachments for Oar-Axles, of which the following is a specification.

This invention relates to a disk-oiler attachment for car-axles and journals, and is particularly adapted for use in connection with mine-cars. The oiler embodying the features of the invention has been specially devised to meet contingencies affecting such devices, both from a standpoint of structure as well as efliciency in operation.

The improved oiler is preferably cast or otherwise produced in one piece and has an open top with an extension to receive the disk which is attached to the car-axle and to provide for a snugly-closing main body or receptacle by inserting the extension around the open top and which is in the form of aflange in the under side of the bolster or other adjacent truck structure of the car. The advantage in forming the main body or receptacle of the oiler inone piece is that it can be more expeditiously applied after disposition on the axle to the truck-frame or bolster or removed from the latter when repair of the truck, axle, or replacement of a worn axle is found necessary. By having the open top formed with a surrounding extension or flange all dirt, grit, or other substance is prevented from entering the main body or receptacle when such extension is embedded in the bolster or truck-frame. Another advantage of the open-top single-piece main body or receptacle is that the disk can be more easily inserted in position within such body for application to the axle, and, conversely, said disk may be by these means more readilydetached.

Other objects and advantages will appear hereinafter, and it is preferred also that the improved disk-oiler be used on a mine-car wherein each axle is rotatable, and has a wheel fixed to one extremity and a loose wheel on the opposite extremity. It will be understood, however, that the disk-oiler may be used in connection with other axle and wheel arrangements.

In the drawings, Figure 1 illustrates a transverse vertical section through a portion of a mine-car, taken in the plane of one axle and showing the improved disk-oiler applied thereto and one wheel loose and the other fixed with respect to opposite extremities of the axle. Fig. 2 is an enlarged transverse vertical section of the disk-oiler shown applied to a portion of an axle. Fig. 3 is an outer side elevation of the disk-oiler. Fig. 4: is a top plan View of the same. Fig. 5 is a section on the line 5 5, Fig. 4:. Fig. 6 is a detail view of an expanding-key forming part of the means for securing the disk to the caraxle.

Similar numerals indicate corresponding parts in the different views.

The numeral 1 designates a mine-car body having a bottom frame 2, which may be of any suitable form for supporting a rotatable axle 3. One wheel L is rigidly secured to the axle by a pin or bolt 5, and the other wheel 6 runs loose on the axle. The object of this arrangement is to have the wheels run independently of each other, so that cars, particularl y mine-cars, can round short curves more readily, and in the event that boxes are set on the bed or truck frame of the car slightly irregularly or askew they will be forced to wear and fit neatly, and at all times the axle must turn and insure lubrication and very little turning of the loose wheel thereon, whereby wear of the wheel-hubs is reduced to a minimum and wabbling of the wheels prevented. The essential feature of the invention, however, consists, as before indicated, of a disk-oiler, including a main body or receptacle '7 of suitable proportions and contour and having upper horizontall y-disposed securing-fianges 8, which are adapted to be bolted or otherwise secured to a truck-frame or the end or bottom frame of the car. The fastening means employed for attaching the main body or receptacle 7 will be of such nature that they can be readily removed. The chamber 9 of the body or receptacle has bearings 10 projecting centrally thereinto from opposite sides, and leading to the said chamber is a filling channel or opening 11, accessible through one of the flanges and normally covered by a hinged closure 12. The flange at the point where the filling channel or opening is located is enlarged or thickened to accommodate the formation of such channel, as clearly shown by Fig. 3. The top of the body or receptacle is open, and the opening is surrounded by an extension or vertical flange 13, which is adapted to be projected into a recess or seat 14, formed in the under side of the truck-frame or bottom framework of the car, and when the body or receptacle has thus been applied and secured in place the chamber 9 will be fully closed and dust, dirt, or grit excluded therefrom, and, furthermore, by the use of this extension or vertical flange any movement of the body or receptacle on the truckframe or body framework or bed of the car is prevented.

A disk 15 is included in the organization of the oiler and inserted through the open top of the chamber 9 in line with the bearings 10, said disk having a central opening 16, corresponding to the diameter of the axle with which it is adapted to engage. After the disk 15 has been inserted in the chamber 9 the oiler as an entirety is slipped over the end of the axle, the latter passing through the bearings 10 and the opening 16 in the disk. The disk 15 also has a pin-opening 17 diametrically formed therein and communicating at one extremity with a key-seat 18, having an inner enlargement extending equally in opposite directions beyond the end walls of the pin-opening to provide means for retaining an extensible key 19 therein. The outer portion of the key-seat 18 is considerably less in length than the inner extension, and hence when the extensible key 19 is inserted in the seat and set it will be prevented from becoming accidentally disengaged. At its opposite terminal the pin-opening 17 communicates with a hole or opening 20 of considerable less diameter than the width of the pin-opening for the reception and operation of a drift to remove'the pin. A pin 21 is inserted in the opening 17, and both the latter and the pin have a rectangular contour, the axle being formed with a corresponding opening to receive the pin. The pin 21 is of such length that when it is inserted in the opening 17 the one end thereof will abut snugly against the inner terminal of the hole or opening 20 and the other end will be flush with the opposite terminal of the said opening 17. The key 19 in its normal condition is bent practically in V shape, so that the ends will pass into the outer portion of the seat 18, and after the said key is thus disposed a sharp blow is given thereto and it is flattened, the terminals thereof projecting into the inner extensions of the seat 18, and thereby securing the pin 21 against accidental displacement. When, however, it is desired to detach the disk from the axle and remove the body or receptacle, the disk is turned 'in such position that the hole or opening 20 will be readily accessible, and by means of small drift inserted in the said hole or opening against the adjacent end of the pin 21 the auxiliary key 19 will be forced out of the seatlS and permit the said pin 21 to be withdrawn. The body or receptacle of the disk is then removed longitudinally off the adjacent end of the axle. The disk 15 rotates in the longitudinal direction of the chamber 9 and is always held below the upper edge of the extension or flange 13 and at such distances from the opposite ends of the body or receptacle as to cause the surplus oil to fall back therefrom into the chamber 9.

From the foregoing description the operation of the device will be apparent. When the axle revolves, the disk picks up and continuously delivers the oil to the axle and is fed by the latter to the bearings 10. The surplus oil between the opposite faces of the disk and the inner terminals of the bearings 10 on the axle will also fall back into the chamber 9, the parts being'so proportioned that there will be ample space for this operation between the opposite faces of the disk and the inner ends of the bearings.

The improved oiler will be found exceptionally convenient in its application and operation, as well as economical in the use of oil or other lubricant.

It will be understood that changes in the proportions, dimensions, and minor details may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed is- 1. In an oiler of the class set forth, the combination with an axle and a car-body, of an oilerbody having all the parts thereof integrally formed and consisting of a lower oil-receiving chamber with a flat'closed top projecting outwardly thereover and formed with a central opening having an upstanding surrounding flange which is fitted against and the opening closed by a portion of the car-body when the oiler is applied to the axle, the body having opposite side openings for the passage therethrough of the axle and inwardly-projecting bearings coincident with the said side opening to receive the axle, the said bearings terminating at a distance outwardly from the vertical center of the body, and a disk removably applied to the axle and held between the inner opposing ends of the bearings and insertible within and withdrawable through the top central opening of the body, the said disk projecting partially upwardly into the top central opening of the body or above the flat top over the oil-chamber.

2. The combination with a car-axle, of an oil-containing receptacle cast in one piece and having an oil-containing chamber and a fiat closed top projecting outwardly over the chamber at opposite extremities and provided with a central opening, the remaining part of the receptacle being tightly closed and the said central opening sealed when the oiler is applied to the axle, the opposite sides of the receptacle having openings therein for longitudinal application to and withdrawal from the axle, whereby the entire oil-containing receptacle may be applied to and removed from the axle with the parts thereof completely intact, and a disk secured on the axle and removably insertible in and withdrawable through the said central opening, the disk being movable with the axle in the receptacle and also having a portion thereof extending upwardly into the cenltral opening above the top of the receptac e.

3. The combination with a car-axle, of an oil-containing receptacle cast in one piece and having a flat top with a central opening and opposite side openings with bearings projected inwardly toward the center of the receptacle and terminally disposed under the said central opening in the top, the bearings being elevated above the bottom of the receptacle, the outer side of the receptacle also having an oil-feeding channel or conduit means communicating with the interior thereof and provided with a cover, the receptacle being longitudinally applicable to and withdrawable from the axle without detachment or separation of any of its parts, and also having its upper central opening closed solely by a part of the car when applied to the axle, and a disk removably secured on the axle and inclosed within the receptacle and extending partially upwardly into the opening, the disk being insertible in and withdrawable through the central opening in the top when the receptacle is shifted to clear the said opening from contact with the car-body.

4. In an oiler of the class set forth, the combination with a car and axle, of a body cast in one piece and having an oil-chamber anda closed top with a central opening and also provided with opposite side openings, -bearings coinciding with the side openings and extending inwardly from the sides of the body toward the center of the chamber and terminating between the central openings in the top, the side openings and the bearings being arranged coincident with the transverse center of the body and the latter projected equally on opposite sides of the axle when applied, the said body as an entirety being longitudinally applicable to and withdrawable from the axle and the central top opening thereof being engaged by a part of the car-body, and a disk removably mounted on the car-axle between the inner opposing ends of the bearings and inclosed within the chamber, the chamber having opposite flat faces spaced from the inner ends of the hearings to permit the oil picked up by the disk to run down over the faces of the latter and the bearings, the disk extending upwardly into the central top opening and insertible in and withd rawable through the latter when the space between the inner ends of the bearings is cleared by withdrawing the body from the axle.

5. In an oiler of the class set forth, the combination with an axle, of a body cast in one piece and having an oil-chamber, a closed top with a central opening, the axle being insertible transverselythrough opposite sides of the body below the central top opening, a disk removably insertible in and withdrawable through the central top opening of the body and of itself having an opening therethrough, the disk when applied projecting upwardly into the central top opening, and securing means removablyinsertible in the top opening of the disk and through the axle, the projection of the disk into the top central opening permitting convenient application and removal of the said securing means with respect to the disk, whereby all the parts of the body may be applied to and removed from the axle without detaching or separating any of the same.
