OIL BECOVERING AND OBTURATING RING.

Application filed December 8, 1925, Serial No. 73,044, and in Belgium December 4, 1924.

The present invention relates to oil recovering and obturating rings for use in connection with lubricating bearings and more es ecially with journal boxes of railroad cars w erein the oil and grease is prevented from traveling along the axle to the dust-guard of the journal box. Such devices usually con sist of a disk or ring secured to the axle of the car which collects the oil as it'travels along the-axle and causes the same to flow by gravity into the oil well of the journal box. However, at times, some of the oil sweeps over the outer periphery of ,the disk and continues its travel to the dust-guard of the journal boxespecially when the car is at rest or traveling at a .low rate of speed and therefore it is the purpose of the present invention to construct an oil recovering and obturating ring of this character whereby the oil will be collected as it passes over the edges of the .ring and likewise better insure the dust. guard against oil accumulating therein which latter would hinder the work in qualities thereof.

he greater the diameter of these rings the better device or stop is provided, but owing to the construction of the journal .boxes and their arrangement in connection with the axle of the car, the diameter of the rings has been limited in order that they may be applied to the axle, and therefore, itis another object of the present invention to provide a ring of this character which may be readil applied within the journal box to the. or inary car axle and yet when the car is in motion the diameter of the ring will increase thereby affording a better obturating means or recovering means for I causing the oil to flow back into the oil well and Figure 5 is an enlarged detail-section of the ring in the form'shown in Figure 1.

Referring now more particularly to the accompanying drawings wherein like and corresponding parts are designated by'similar reference characters throughout the .several views, the numeral 1 indicates the car axle having the usualjournal box 2 applied thereto. The rear portion of this journal box is provided with the usual recess 3 in which is applied the dust guard of any well known or preferred construction. The journal portion 4 of the axle receives the usual brass 5' of the journal box and the axle isalso provided with the usual shoulders, one indicated by the numeral 6, upon which travels the dust guard and the other indicated by thenumeral 7 to which is applied the oil deflector for preventing the oil from passing from the journal portion of the axle to the rear of the journal box and'thereby preventing any of the oil from contacting with the dust guard arranged within the recess 3. The oil as it is collected by these deflectors is caused to drop by gravity into the oil well 8 of the journal box.

The improved oil recovering and obturatto receive the threads arranged upon the shoulder 7 Formed with the outer marginal edge of the disk 10 is an annular flange 11. The inner walls of this flange 11 are beveled outwardly so that the oil collected within the same will'be permitted to flow by gravity into the oil well 8 of the journal box. However, at times, a portion of the oil will passover the outer periphery of this flange 11 and such oilcpassing over the outer periphery of this flange 11 will when the car is running at low speed or stopped, gradually flow back into the recess 3 of the journal box thereby interfering with the good working of the dust guard. To prevent this oil from sweeping back into the car as is illustratd in Figure 1, or they may be secured thereto in any well known manner, but the diameter of such rings has to be limited in order that they may be inserted upon the axle within the journal box thereof and therefore I have provided a deflector as is illustrated in Figures 2 i to at inclusive, of the drawings whereby it may be tilted at various angles when inserting it along the axle so as to pass under or by projections within the journal box, such as the projecting inner ledge of the upper wall of the journal box which holds the brass 5.-

From the construction as shown it will be noted that the central opening within "the ring is of greater diameter than the exterior diameter of the journal portion of the axle, so that when applying itito the axle it may be tilted at various angles and thereby pass the projections within the journal box to its supporting shoulder 7. In this form of a ring the hub portion 9 as is illustrated in Figures 1 and 5 of the drawing is elimi- 'nated but the body portion of the ring is 'd d H liralit of o enin s 13 the. Pl V1 6 W1 1 1 p L y P g the ring directly into the Well 8 of the journal purpose of which willbe later described.

In Figures 2 and 3 of the drawings I have illustrated two ways of applying this -movable recovering and obturating ring to the car axle. Secured to the shoulder 7 of theaxle and of suliicient length to abut against the enlarged shoulder 6 ofthe same axle is a sleeve 1 1 having an annular flange formed with the outer end thereof. This annular flange 15 is provided with a plurality ofv pins 16 which are adapted to extend through the openings 13 formed within the ring. This sleeve 14 may be welded,

threaded or in any well known or preferred manner connected to the shoulder 7 of the' axle. After the ring has been inserted upon the axle and the pins "16 projecting therethrou 'h a ring 17 maybe placed upon the shoulder 7 at the outer side of the ring and connected to the pins to prevent longitudinal movement of the ring.

In Figure 3 of the drawings 1 have illus trated a. modification whereby the sleeveli is eliminated and two rings 18 and 19 respectively are employed for retaining the deviceupon the axle. These rings 18 and 19 may be secured to the shoulder 7 of the axle in any well known or preferred manner so as to prevent any longitudinal movement of the 11 rom the foregoing it is obvious that by employing an oil recovering and obturating ring as herein shown and described any oil that attempts to pass over the periphery of the ring will collect within the grooves 12 and when the car is at rest or traveling at a low rate of speed the oil will travel down around these grooves 12 and flow back to the oil well 8 of the journal box thereby preventing this oil from flowing back and interfering in any manner with the ood working of the dust guard. When the form of ring shown in Figures 2 to 4 inclusive of the drawing is employed and applied to the axle it will be noted that this ring will assume the position as illustrated in Figure 2 of the drawings when the car is at rest but when the car is in motion the ringwill assume the position as is illustrated in the Figure 8 or concentric to the axle. This sliding movement of the ring is permitted due to the fact that the openings 13 are of greater diameter than the exterior diameter of the pins 16. The ring by assuming that position as shown in Figure 2 will be disposed eccentrically with respect to the axle receiving it and consequently upon such eccentric positioning, it will be understood that the lower portion of the ring will afford a greater obturating area at the under surface of the axle, serving to positively prevent the passage of oil rearwardly of the lower portion of the ring into enga ement with the pocket or chamber 3, but to t e contrary, effecting a return of such oil from box. in applying the device to railroad cars it is first necessary to raise the journal box and weight carried thereby from the axle 1 but it is impossible to raise the journal box to a height whereby rings of large diameter may pass by the projections within the journal box a'nd'by enlarging the central opening of the ring to a diameter greater than that of the exterior diameter of the axle the ring may be readily inserted thereon and pass by the projections within the journal box to its final position upon the axle where it may, be fastened in place.

'During the travel of the car the ring will of course move with the axle and the centrifugal motion transmitted thereto will cause the ring to rise from an eccentric or normal position aS shown in Figure 2 to a concentric or Working position as is shown in Figure 3 of the drawing.

Manifestly, the construction shown is capable of' considerable modification and those modifications as are Within the scope of my claim I consider within the spirit of my invention.

I claim:

An oil recovering and obturating ring for journal boxes of railway cars comprising in combination with a shaft, a sleeve rotating with the shaft, a plurality of projecting ins secured to and extending long tudinally mm 10 said sleeve, a disk having an-opening therein of greater diameter than the exterior difor receiving the latter, an annular flange formed with said disk and a ring secured to the outer free ends of said pins for retaining the disk upon said pins.
