CONTINUOUS AUTOMATIC LUBRICATGR.

Application. filed September 20, 1927, Serial 170.220,?90, and in Mexico'May 2S, 1927.

This invention refers to improvements in automatic and continuous lubricators forv railway car journals.

The lubricator according to the present invention does away with the use of cotton waste completely and economizes in the use of oil andgrease. It works automatically by the rotation of thejournal and efiects a continuous lubrication of the same without any waste of oil, as this oil returns to the oil chamber after having passed around the journal, and from there it starts again on its travel by means of the special elevator, which constitutes one of the main features of the invention.

The invention as illustrated in the accompanying drawings is adaptable for the ordinary journal boxes now in use, but it is also intended that this new lubricator be manufactured incombination with and as a part of the said journal boxes.

In the accompanying drawings:

Fig. 1 represents the lubricator placed on the journal of'a railway car inside of the usual journal box.

Fig. 2 represents a sectional View of the lubricator, showing the'elevator, in section, placed on the rim of the journal of the railway car, and showing also in section the oil chamber.

Fig. 3 is a sectional View of the lubricator, the journal of the'railway car, the canal or lubricating chamber which lubricates the journal, and the oil chamber.

Fig. 4: is a sectional view of the elevator placed on the rim of the journal of the railway car, and the oil chamber.

Fig. 5 is a side View of the elevator.

Fig. 6 is a sectional front view of the lubricator, showing the elevator placed on the rim of the journal of the car and in the act of lifting the oil up from the oil chamber to the canal or lubricating chamber which lubricates the journal.

Fig. 7 is a perspective View of the whole lubricator with parts being broken away to show the interior.

Same numbers of reference throughout all the figures indicate same parts.

With reference to the drawings: 1 is the lubricator; 2 is a wedge which forces the lubricator to remain in contact with the proper journal of the car; 3 is a plate which is placed at the bottom of the journal box 00, which is the usually used; 4: is a rein- The elevator is fixed to therim of the journal .of the railway car by means of screws 8 or other mechanical means. The rim is numbered 6.

'9 is the oil chamber in the lubricator. This chamber has placed on its cover a lubricating chamber 10 which is formed as a canal 11, open in its upper part for the ad-' mission of the journal, and in which canal the journal will rotate and be lubricated. There is a space between the surface of the journal and that of the said canal. This canal receives oil from the elevator which raises it from the oil chamber and delivers it on the inclined planes 12 and 13 by means of the rotarymovement imparted to it by the journal, and by means of the chambers formed in the said elevator 7 by the spaces 20 and the cover 1 1. These spaces are filled with oil from the oil chamber 9, and when one of'these chambers'filled with oil reaches the upper part of the canal, the oil will pass on to the inclined planes 12 and 13 by the openings 15 and 16, and from there it will flow down into the canal 11 by its own weight. The lubricating chamber is provided in both ends with borders which fitto the surface of the ournal, thus preventing oil from running out of the lubricator or back to the oil chamber before lubricating the journal.

The oil enters into the lubricating chamber and lubricates the journal, and the remainder or excess oil goes back to the oil chamber through the perforation 17 in the bottom of the lubricating chamber at the opposite end to that in which the. elevator is located.

The apertures 15 and 16 are provided with upper flanges 18 and 19 with the object of forcing the oil to run down the inclined planes 12 and 13, and the borders 20 and. 21 are placed so as to prevent the oil from dropping outside of the lubricator on the sides. B indicates the journal bearing which forms part of the usualjournal box. 22 is the inlet for the oil to the oil chamber and is provided with a lid. 7

Our lubricator works as follows:

The whole structure is placed inside the usual journal box of a car and fastened by mechanical means, then the elevator is fixed firmly at the end of the journal of the car, either on a rim on said journal or otherwise, and the cover in form of a circular boX open on the inside is slipped over the said elevator. Then the oil is poured into the oil chamber, and when the journal of the car rotates the elevator will rotate with it, and

,each space between two projections on the inner face of the elevator will form a chamber with the circular chamber and thus carry oilupwards to the lubricating chamber.

Between the lower ends of the flange on the inside of the top of the circular chamber and the adjacent ends of the lubricating chamber placed on top of the oil chamber, there are provided openings 15 and 16 through which the oil goes onto the inclined planes l2 and 13 which form, on each side, the upper borders of the lubricating chamber, and from which it runs down into the lubricating chamber proper guided by the flanges 18 and 19 thus lubricating the jour-- nal. After having lubricatedsaid journal sufficiently the remainder or excess of oil will drop through the perforation 17 down into the oil chamber and so on continuously.

Having thus described our invention what we claim is:

l. A continuous automatic lubricator for railway journals, comprising a horizontal oil chamber, a circular chamber open in one of its faces and fixed perpendicularly to one end of the said horizontal oil chamber, which opens into the said circular chamber; an

elevator in the form of a disc fixed to the journal, said elevator being provided with projections on the surface of its'inner face, said projections forming a circle; a lubricating chamber above the horizontal oil chamber forming a horizontal canal running in the same direction as the journal, said lubricating chamber providing a space between it and the surface of the canal, the upper edges of said lubricating chamber being inclined towards the centre of same; said lubricating chamber having an aperature for the passage of the oil down into the oil chamber, each extreme of the lubricating chamber being provided with borders which adjust to the form of the ournal and said elevator be ing arranged to lift oil from the oil chamber to the inclined upper edges of the lubricating chamber.

2. A continuous automatic lubricator for railway journals comprising a horizontal oil chamber, a lubricating chamber on top of said oil chamber, for receiving the journal having inclined and upright flanges; an elevator fixed to the journal, said elevator being covered with a circular chamber which communicates with the said oil chamber in its lower part and is open on its inner face; the upper half of the circular chamber being provided with an inner flange; an opening on each side between the circular chamber and the adjacent portion of the lubricating chamber on top of the oil chamber, for the passage of the oil from the elevator to the inclined flanges of the said lubricating chamber, said upright and horizontal flanges preventing oil from dropping outside of the lubricator.
