PATENT `THOMAS SAYLES, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN CAR-AXLE LUBRICATORS.

Specification forming part of Letters Patent No. 107,631, dated September 2i), 1870.

To all whom it may concern: l

Be it known that I, THOMAS SAYLEs, of Chicago, in the county of Cook andV State of Illinois, have invented certain new and useful Improvements in Car-Axle'Lubricators; andI hereby declare that the following is a full, clear, and exact description of the same, referencebein g had to the annexed drawing, which forms part of this specification.

This invention relates more particularly to certain improvements in alubricator for caraxles which form the subject of Letters Patent ofthe United StatesV granted on the 416th day of March, 1869, to Isaac P. Wendell and Thomas'Sayles, as the sole assignees of one Mark G. Hubbard, the inventor of said improved lubricator. l

'.Ihe invention consists in providing the padholding chamber with rims or upwardly-projectin g han ges, whereby the pad, which comes in contact with the journal when the lubrica-v tor is in position, will be retained in place wlthout sewing, and in such manner that it can be removed when worn, and replaced by a new one, without removing the `lubricator from the journal-box.

It further consists in the combination, with the pad-holding chamber and its supportingspring and wick or oil-conductor, of a sponge or other suitable absorptive material, placed wholly or partially within the said sustainingspring, for purposes hereafter to be described.

It further consists in the combination', witha pad-holding chamber and its sustainingspring, of a jacket which incloses the spring in such manner as to prevent-the dust anddirt, which is constantly entering the journalbox, fromlodging upon and adhering to the wick or oil-conductor, and thereby greatly impairing its conducting qualities 5 and it serves also to prevent the surging of the oil inthe box while the train is in motion,Y and consequently'the leakage of oil from the oil-box.

It further consists in the combination, with "suchIpad-holding chamber and wick` or oil conductor, of a protecting covering, placed over said wick in such manner as to protect it -from l the dust, which enters the box and wouldotherwise adhere to it in quantities sufcient to impair its qualities as an efcientconductor of the lubricating-liquid to the pad or pads.

In the accompanying drawing, Figure l is a longitudinal vertical section of a journalbox, showing, partly in section and partly by ,side elevation, the improved lubricator above referred'to, and also showing my present improvement applied thereto. Fig. 2 is a transverse vertical section of the same. Fig. 3 is a longitudinal vertical central section of the padholding plate, alone.

y A designates a car-journal box; B, the journal, with a collar, a, upon its end, and (l the journal-bearin gs, all of the construction in common use. D is a curved plate, provided with a chamber, E, into which chamber is placed a p`ad,b, of felt or other fibrous material of suitable absorptive qualities, which padis supplied with thelubricating-liquid by means of a wick or other suitable conductor, c.

The said pad-holder D is held up, so as to keep its pads ortheir equivalentpressed against the journal, by a spring-a spiral spring, G, for instance 5 'and I will here remark that I prefer to makepthe lower coil or coils of such spring ofsuftlcient diameter to extend laterally across the box, and consequently maintain its position in a better manner than when the coils are of equal diameter, as shown in the patent hereinbefore referred to. The wick passes down the inside of the spring, over the edges of the plate D.

The pad-holding plate D is provided with a lugV or projecting piece, d, at one end, and in such manner as to extend under the collar a on the end of the journal 5 and the said plate is also provided with rims or upwardly-projecting llanges e e e e at its corners, for the purpose of holding in place a pad of felt or other suitable absorptive material, b', which pad is held in contact with the journal, and supplied with the lubricating-liquid by means ofthe wick c and pad b. The advantages arisin g from the combination with the pad-holdin g plate of the lug (l and rims e will be readily understood.

The pad b is out of such size as to iit upon the plate D and be retainedin place by the rims e without the necessity of sewing it in position, as was found necessary to do with the corresponding pad. upon a plate of the construction shown and described in the said patent to Wendell and Sayles, and hence the pad b can be removed and replaced without any trouble whenever it is necessary so to do.

`The lug d, when the pad b' is new, lies some ritten.

distance below the collar of the journal, as

shown in Fig. 1,and as the pad wears the said lug comes closer and closer to the said collar, and in this way the exact condition of the pad b can be ascertained; and, moreover, by placing the hand upon the lug d the plate D can be tipped so as to permit the withdrawal of one pad and insertion of another.

F designates a jacket, which incloses the spring G. Thisjacket may be made of any suitable material. This jacket performs two very important functions First, it surrounds and incloses the wick or oil-conductor c, and prevents the dust and dirt,whicl1 enters the journal-box in large quantities, from adhering to the wick, and thereby materially impairing its efficiency as an oil-conductor. By thus protecting the wick it is at all times in operative condition as an oil-conductor. Second, the spring, with this jacket applied to it, on account of the p0- sition of the spring in the journal-box, forms a partition, which will prevent the surging of the oil from end to end of the box, as will be clearly understood by reference, rst, to Fig. 2, where its position across the box is shown, and then to Fig. 1, where the oil is shown as contained on each side of it. It will therefore be observed that the oil cannot acquire sufficient momentum to slop out of the journal-box to any extent.

H designates apiece of sponge applied to the lower part of the wick for th'e purpose of absorbing oil and keeping` the wick well fed with the same. As an equivalent for a sponge, any suitable material which will absorb the lubricating-liquid will answer.

I, Fig. 2, designates the covering, of any suitable material, which is placed over the wick where the same emerges from the spring to cross the plate-that is, it is arranged so as to cover the exposed parts ofthe wick, and its office is to shield the Wick from the dust which enters the journal-box, dust oft-en entering the box and lodging and adhering to the wick in such quantities as to impair the efficiency of the wick as a good conductor of the lubricating-liquid.

The covering I eftectually shields the exposed parts of theWick, and is a most desirable feature iu a lubricator of the construction herein described and referred to.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combinati0n,with a pad-holdin g plate, D, of rims or upwardly-projecting flanges e, secured to or cast with the said plate, and forming guards to prevent the pad from accidental lateral or longitudinal displacement, substantially as and for the purpose herein specified.

2. The combination, with the pad-holding" plate D, spring G, and wick or conductor c, of a jacket, F, substantially as and for the purposes herein specified.

3. The combination, with a spring, G, plate D, and wick or oil-conductor c, of a sponge, H, or other suitable absorptive material, to

act either as a feeder to the wick or as a barrier or partition across the journal-box, substantially as and for the purpose herein specified. f

4. The combination, with the wick or oilconductor c and pad-holding plate D, of a covering, I, to act as a shield for the said wick, substantially as herein specified.

THOS. SAYLES.
