CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters 1 atentNo.592,910, dated November 2, 1897. Application filed January 20, 1897. Serial No- 619,838. (No model.)

To all whom it may concern.-

Be it known that I, WINFIELD S. HAINEs,

a citizen of the United States, residing at Gladstone, in the county of Delta and State of Michigan, have invented certain new and useful Improvements in Oar-Axle Lubrioators; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its especial object to provide an efficient, reliable, and'durable lubricator for car-axle journals, but is capable of use in other applications for lubricating a journal or shaft upon which the load is carried from a top non-rotary bearing in cooperation with the journal.

To these ends my invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein, like notations referringto like parts throughout the several views Figure l is a central longitudinal section on the line a." w of Fig. 2 with some parts broken away and others'shown in elevation. Fig. 2 is a horizontal section on the line x x of Fig. 1 with some parts broken away and others shown in plan.

ing as they would appear when detached and pulled apart from each other, and Fig. 4: is a detail in perspective showing the lock chip or key detached.

The car-axle is of the usual form, and for the purposes of this case it will be convenient to note the body portion a, the journal a, the inner flange a and the outer flange or collar a The main box bis also of the usual form, and it is only necessary to note the lock notch or shoulder b and the slot or recess b for the sectional dust-guard b c is the bearing-brass of the usual form, and

c is the lock chip or key for cooperation therea Fig. 3 is a perspective view showing my oil-well and the brass or top bearwith. The brass c is provided with the usual inner end flange o, and thelock-chip c is of the proper form to engage over the top of the brass with one end abutting against the flange o of the brass and the other end abutting against the lock notch or shoulder b in the main box I) for holding the parts in proper workin g position.

Turning now to my improvementl provide an oil-well ff of the proper form to embrace the journal a and afford a receptacle for a body of oil in which the journal can run. This oil-well f f is of such shape as to be carried on the journalflanges a and a and is provided with a top slot f? for the passage of the brass. or top bearing 0. The said well is also provided with a supply-duct'f, which is normally closed at its top by a cover J. The outer end of the well-body is also provided with a horizontal lug f having a concave face forcoop'eration with a spring f or other equivalent device for holding the well from endwise displacement when in working position. The spring f is shown as engaging with eyebolts f tapped into the vertical walls of the main box I). The body portion f of the oil-well is enlarged relative to the size of the portion f and is recessed, as shown at f, for affordin g a seat for the journal-flange a Otherwise stated, the part f is of the proper shape to adapt the outer end of the well to fit over the journal-flange 06. The inner end of the sleeve or reduced portion f of the Well is provided with a collar or flange f for abutting against the car-wheel 7t, as shown in Figsx'l and 2. The groove b in the main box I) for the sectional dust-guard b is of the proper vertical length to permit. the dustguard to move up and down therein and to be entirely removed therefrom through the top in the usualway.

To mount the parts in proper working position, the dust-guard 12 being made in sec tions; as before stated, the following plan may be followed: The lower section of the dust-guard having been placed in position in the main box I), the oil-well f f is introduced into the box with the portion f projecting therefrom at its back. The top section of the dust-guard If is then applied. The main box Z) and the oil-well f f are then slipped over the journal together and turned upside down. The weight of the main box I) will then cause the same to drop sui'ficiently far below the journal to afford clearance for introducing the brass c and the lock-chip a into their proper relative positions. The main box I) and the well f f are then turned upward into their proper positions for cooperation with the truck-frame.

The above plan would be followed when mounting the parts on a detached axle. If it is desired to apply the oil-well to an axle in working position under the car, the same can be done by first jacking up the box I), then inserting the oil-well through the open end of the main box and applying the same to the journal, then positioning the brass c and the lock-chip c and, finally, applying the upper section of the dust-guard and lowering the main box 1; into working position.

Vhen the oil-well ff is in working position, it must be obvious that it is carried by the flanges a and a of the journal in a stationary position. The bearing-brass 0, working as it does through the slot f in the oilwell, engages with the side wallsof the slot, filling the opening f and preventing the oilwell from rotating with the car-axle. The brass is itself held by the chip or key 0 and the weight thereon from the main box Z) together with the load from the car. The lock chip or key 0 conforming in cross-section to the angular surface of the brass c, securely holds the brass from slipping rotatively in respect to the lock-chip on the main box I) The well f f being filled with oil up to or nearly to the top of the supply-duct f it is obvious that the journal a will run in a bath of oil. Hence the journal will be perfectly lubricated. The oil will also work out onto the journaldlanges a and (t and afford an abundance of lubrication between the said flanges and the parts of the oil-well ff, which engage therewith. The only weight, however, on the journal-flanges a and a is that of the oil-well itself. Hence there is little wear and tear between the journal-flanges a a and the cooperating parts of the oil-well. As the oil-well itself does not rotate, there is no wear and tear on the dust-guard b Hence a tight joint is insured at that point. The well f f, in cooperation with the bearingbrass c, which fills the slot f in the well, completely covers the axle-journal. Hence dust and dirt is excluded at the top and front. The spring-action clamping device f serves to hold the oil-well with its rear-end flange 9 abutting the car-wheel, thereby maintaining a tight joint at that point. The fact that this keeper or clamping device operates with a spring action enables the same to take up any wear that may occur on the rear end of the oil-well from the car-wheel. Any other suitable form of spring-action keeper or clamping device might be substituted instead of the coiled spring shown.

From the foregoing it will be seen that the journal is protected from dust at all points.

By the simple device herein desoribed,therefore, I have provided a lubricator for car-axle journals, which affords a constant bath of oil for the journal,which is dust-proof, and which is subject to extremely little wear and tear under the service. For removing the oil-well it is obvious that the keeper-spring f may be unshipped, and by then reversing the mounting action hereinbefore described the well can be readily removed.

The construction herein described may be changed in its details to some extent without departing from the principle of the invention. It will also be understood that although cspecially designed for car-axle journals the invention may be elsewhere used on any journal whereon the load is carried from the top in cooperation with a suitable brass or other bearing.

It will of course be understood that the expression bearing-brass as used in the specification and in the claims is not intended to limit said claims to the use of this particular material. The expression is simply used because of its fixed and well-known use in the trade.

\Vhat I claim and desire to secure by Letters Patent of the United States, is as follows:
