LUBRICATING- APPARATUS.

Specification of Letters Patent.

Patented Oct. 13, 1908.

Application Iled February 11, 1907. Serial No. 356,668.

To all whom it may concern.:

Be it known that I, CHARLES B. ROYAL, a citizen of the United States, residing at `Oak Park, in the county of Cook and State of Illi- V nois, have invented certain new and useful Improvements in Lubricating Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in 'the art to which it appertains to make and use the same, reference being-had to the accompany ing drawings, and to the letters and figures of reference marked thereon, which form a part of this specication.

My present invention relates to a lubricating device, and more-particularly to one for .use in lubricating journals on locomotives,

the object of Iny invention being to provide a continuous liquid lubrication for the journal on its lower or free side.

In accomplishing this object, I have provided the improved details of structure which will presently be fully described and ointed out in the claims, reference being ha to the accompanying drawings forming part of this specication, and in which,

Figure I is a'view in side elevation of a journal box, and parts of a lubricating device constructed according to myinvention, showing the locomotive axle in cross section. Fig. II is a view in end elevation of the journal box, and bracket supporting arts of the lubricating apparatus. Fig. II is a to plan view of Fig. I. L Fig. IV is an inverte plan view of the journal box with the lubricating parts and axle removed. Fig. V is a Side view of the journal box and parts, sectioned on the line V-V, Fig. II. Fig. VI is an end view of same on the line VI-VI, Fig. I. Fig. VII is a perspective view ofthe sliding cellar block. Fig. VIII is a similar View of the cellar supporting bracket.

Referring Inore in detail to the parts,-1 indicates a journal box, having the side flanges 2 inclosinga body portion 3, and is provided in its upper body portion, between the said flanges, with a chamber 4. Box 1 is provided with the usual journal opening 5, at the top of which is secured a brass 6 shaped to receive the axle journal 7.

At the lower outer endof each of flanges 2 is an offset 8 and fitting against the edges of the offsets and against the inner edges of the lower ends of body 8 are the flanges 9 and 9 of the supporting brackets v10, there being a pin 11 projecting through said flanges, and

the lips of said body portion for the purpose of retaining the bracket firmly in position.

12 indicates studs on the upper faces of brackets 10 which fit within perforations 13 in the bottom of the body arms for more firmly anchoring the parts. tween the lower arms of the box body are the studs 14, and seated on the brackets oversaid studs are the coil springs 15, which support the lubricant cellar block 16 yieldingly against journal 7. Block 16 is provided with end ribs 17, which fit within the grooves 18 in the body arms, and serve as guides during the vertical` travel of the cellar block in the opening between the body arms. Block On brackets v10 be- Jj- 1.6 is provided at its corners with cut out portions 19, which fit over the flanges 9 of bracket 10 to permit said block to seat against the bottom of the bracket. Block 16 has a rounded upper surface and is hollowed out to form a cellar 20 for containing the lubricant,

which latter escapes through a slot 21 in said upper surface.

23 is a babbitt lining which extends around the upper edges of block 16 and around the edges of slot 21, forming a bearing for the journal. p

. Extending downwardly from chamber 4, through the body ofthe box is a channel 24, provided at its lower end with a plug 25 for retaining the liquid lubricant therein, and extending through the inner side of the box body into channel 24 is a tube 26, on which is secured a flexible tube 27, the latter in turn being secured to a short tube 28, which extends through the bottom ofthe cellar block 16 into the chamber 20.

29 is a channel in the upper part of the box body, adapted to register with the channel 30 in the brass 6, b Ameans of which the lubricant is fed direct y from chamber 4 to the upper portion of journal 7.

31 are pins extending through the upper portions of the box body, into brass77 6 for the purpose of retaining the latter in position.

When in use, the parts are arranged as described, and chamber 4 filled with a lubricating oil, which passes through channel 24, and the flexible tube 27, into the chamber in the cellar block 16. When such chamber has been filled, the oil will pass upwardly through the slot 21, into contact with the journal.

As the brass wears away the cellar block is forced to follow upwardly by means ofy the compression springs, so that the cellar block will always be in the proper position for lubricating the journal, irrespective ofthe condition of the other parts; the flexible tube permitting the vertical movement of the cellar block without affecting the lubricant feed and ribs 17 guiding its upward travel. If so desired, the lubricant su ply may be carried in another position and feed to the cellar by a longer tube, although the construction shown is preferable.

With a device of this construction it is possible to constantly provide the journal with liquid lubricant from the bottom or free side of the box without the use of waste or like material; and to provide a close or tight bath irrespective of the wearing of the brass.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent isf- 1. A lubricating apparatus comprising a journal box,\a chambered cellar block slidably mounted in saidbox, alubricant receptacle, and a conduit connecting said receptacle and the chamber in said cellar block, said conduit being iiexible for a portion of its extent.

2. A lubricating apparatus comprising a journal box, a cellar block carried by said box, a lubricant receptacle, a conduit leading from said receptacle, and a 'liexible tube connecting said conduit and cellar block.

3. A lubricating apparatus comprising a l journal box, having a recess opening through the bottom, and a lubrican 3receptacle at the top, a cellar block slidably i ounted in said recess, and yieldingly tensioned upwardly therein, said box being providedwith a conduit leading from said receptacle, and a ilexible tube leading from said conduit to said cellar block.

et. The combination of a journal box, having a body portion provided with a lubricant receptacle at its upper end, and with a conduit extending downwardly therethrough,

an axle journal having a seat in said box, a

lubricant cellar block yieldingly supported against the bottom of said journal, and having an interior lubricant chamber, and a ilexible tube connecting said chamber and the conduit in said box.

5. The combination'ol a journal box having a conduit extending therethrough, a plug closing the lower end of said conduit, an axle journal having a seat in said box, a lubricant cellar block supported against the lower side of In testimony whereof' l allix my signature in presence of two witnesses.
