Application December 18, 1931 Serial No. 581,949

5,Claims. '(Cl. 308-88) This invention relates to lubricating apparatus for journal boxes and more particularly to journal boxes used on railway cars, locomotives, etc. The invention constitutes, to some extent, an improvement upon my application, Serial No. 513,- 0 42, for Lubricating apparatus for railway journal box.

An object of the invention is to provide lubricating apparatus which will supply a uniform and even flow of lubricant to a journal, and which maybe readily removed and inserted -within a railway journal box. A further Objectis to provide improved resilient means for maintaining a lubricant bearing material, such as felt,

against a side wall of Vthe journal. Another object is to provide sealing means for preventing the escape of lubricant along the journal wall and for preventing the ingress of dust, etc. into the interior of the journal box. Other objects and advantages will appear as the specification proceeds.

The invention is fully described in the following specification and shown in the accompanyingV drawings, in whicln- Figure 1 is an end sectional View of apparatus embodying my invention, the section being taken as indicated at line 1 of Fig. 3`; Fig. 2, a transverse sectional view, the section being taken as indicated at line 2 of Fig. 1; Fig. 3 a vertical sectional View, the section being taken as indicated at line 3 of Fig. 1; Fig. 4, an enlarged detail sectional View of the sealing strip employed near the rear of the journal; Fig. 5, a front viewV of the lubricating apparatus; Fig. 6, a plan view ofthe lubricating apparatus, removed from theA journal box; Fig. 7, a broken sectional detail View of a spring hinge employed in the preferred form l.of my invention; and Fig. 8, a'front, partly sectional View of a modified form of lubricating device constructed in accordance with my invention.

Y In the preferred form of lubricatingapparatus,

illustrated in Figs. 1 to 7, inclusive, A designates a journal box which may be of the usual or any suitable construction. The box is shown equipped with a hinged cover B. As lshown more clearly in Figs. 1 and 2, the box A isprovided at an inter-r mediate point with integral lugs C which provide shoulders atC.

Secured within the upper part of the journal box is a bearing D which may be of any suitable construction. As illustrated, a journal E engages the bearing D and is provided at its outer end .with a collar E.

My improved lubricating apparatus comprises generally frame mechanism for supporting strips of lubricant bearing material, such as felt, yieldably against the side walls of the journal, means for spreading the frame to permit ready removal thereof from the journal box, means for limiting the swing of the lubricant bearing strips of felt, and also resilient means which prevent the escape of lubricant from the journal box;

In the illustration given in Figs. 1 to '7, inclusive, 10 designates strips or pads formed of felt or other suitable material.l The felt pads are yieldably supported within frame l1. As shownv more clearly in Figs. 5 and 6, the frame comp-rises a substantially U-shaped front member 12 and a similar rear U-shaped member 13. The front and rear members l2 and 13 are connected by side rails 14. Short bracket spurs 15 are secured to the front and rear ends l2 and 13, and Y are preferably twisted or turned slightly. The

hinge member 17. The upper flange 18 of the hinge is secured to a frame strip 19 which is secured to one of the felt pads 10. The hinge 17, which is of a' well known construction, is provided with a spring 20 and the iianges 16 and 18 are so positioned as to contact when the pads 10 are swung to the inner position, shown more clearly in Fig. 5, thus denitely limiting the inward swing of the lubricating pads.

As shown more clearly in Figs. 1, 2, 5 and 6, the forward ends of'frame strips 19 are turned to form cam spurs 21, these cams being adapted to engage .theinner side of the journal collar E' and to spread theinner frame memberslQ and pads 10 as the lubricating Yapparatus is drawn forwardly to remove it from the box. `In order to permit full outward swing of the members 19 and cams 21, the front end member 12 is bent outwardly to form half loops 12a. Y As the members 19 and '21 swing outwardly, they enter the loop portions 12a and enable the felt members 10 to be retracted sufficiently to clear the collar E of the journal E. f y

One of the diiiiculties which has attended the use oi lubricating apparatus of this type has been the loss of lubricant along the rear side of the journal, the -lubricant within the box being un, confined and free to flow within ythe box, is sub'- jected to violent vibration and is thrownv or splashed about the box and particularly along the rear side of the journal. The lubricant has had a tendency to iiow along the rear portion of the journal wall and to escape under the portion of the axle adjacent the journal and journal box. I have found that .this difliculty can be overcome by providing a sealing strip or wall of felt or other suitable material and shaping it so as to embrace the bottoms andvsides of the rear portion o the journal. As shown more clearly in Figs. 3, /i and 5, the felt wall 22 is supported by the vertical flange 24 of an angle iron connection 25. The connection 25 is secured by suitable means to the rear end piece 13. Preferably, the rear wall 22 is cut away centrally along a circular line 25 'to receive the journal E and thus forms a tight seal about the lower portion of the journal.

In addition to serving as a baiiie or back stopv chamber at a point between the journal box andV the adjacent axle portion.

In order to insure the apparatus against the jar and vibration to which it is subjected in the journal box, I prefer to extend the felt pads l0 so as to provide a cushioning portion 10a below the bottom of the metal frame. This extension may be from one-half to one inch long. Also, I prefer to provide baffle 22 with a similar cxtension 22a, which supports the rear part of the metal frame above the bottom of the journal box and also forms a seal against the bottom'oic the journal box.

Any suitable means may bev employed to secure the felt wall 22 to the resilient support 23 and the felt walls 10 to the inner frame member 19. In the illustration given, split rivets 27 are employed.

In the operation of the device, the frame may be inserted within the journal box by spreading the spurs 21 and bending the resiliently supported rear wall 22. After the framev has cleared the collar E( of journal E, the spurs may be released, thus allowing the :telt pads 10 to be drawn up, against the sides of the journal. In this posi-V tion, the tops of the side and end walls will abut shoulders C of the journal box and will be held againstlrotary movement. The collar E also cooperates with the rear wall or the box to prevent.

longitudinalmovement oi the lubricating device.

Any other suitable means, however', may be em-y l Vdirectly forward pull, thus bringing the spurs or.

spreaders 2l in contact withthe inner vwall or the collar E', and serving to spread the entireA inner frame 19 and felt pads 10 so as to clear the collar E. permit wide retraction ofA the spurs 2l and inner frame member 19. The rear felt wall 22` yields together with the Vresilient strap 23 and jthus;

clears the collar E'. y Y

Inthe modified form of apparatus illustrated Ealfloops 12a of the end,y .member 12" in Fig. 8, the' felt pads 28 are supported by re-1 silient spring strips 29 which are secured to the frame in the manner described in my application, Serial No. 513,042. In order to prevent the felt pads 28 from swinging inwardly to substantially collapsed position, I employ chains 30 which are secured to the frame 31 and to the top portion of spring strips 29. A sealing wall 32, substantially as describedY in connection with the preferred form of apparatus, is secured to the rear frame member 3l.

' The lubricating apparatus, both in its preferred and modified form, eects a tight sealing of the journal box against escape of `lubricant and the infiow or dust; also, the apparatus may vbe readily inserted and withdrawn from the box in a very short time and with a minimum of effort.

The foregoing detailed description has been given forfclearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended.claimsl should be construedas'broadly as permissible, in view of the prior art.
