j amen STATE PATENT OFFICE.

To (all whom it may concern.-

Be it known that I, Jornv STUART SMITH, a citizen of the United States, residing at Me- Henry, in the county of Ohio and State of Kentucky, have invented a new and useful.

Lubricating Car-Wheel; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- 1o pertains to make and use the same.

This invention relates to railroad-cars, and moreparticularly to the wheel, having novel lubricating meansfor continually supplying the oil to the journal of the wheel. I

The object of the invention is to provide a device of this character which is simple in construction and which can be manufactured altavery slight cost and at the same time be sold to the trade comparatively cheap.

Another objectof the invention is to provide a chambered portion in the body portion of the wheel in which the oil is adapted to be contained, so that-by the centrifugal motion of the wheel the body part of the 01] will have a tendency to adhere to the outer portion of the chamber and will only allow a small quantity to spray therefrom in the rotation of the wheel.

A further object of the invention is to provide a eylindr1calshaped cap which is insex ted over the end of the axle for the pur pose of holding the wheel,in correct position in relation to said axle, said cap being provided with oil-ducts which are slightly in- 3 5 clined to allow the oil to find its way to the chambered portion.

"A still furtherobject of the invention is to provide means for automatically closing the end of the cap after oiling.

This invention comprises, further ob'ects and combinations of elements, which wi l he hereinafter more fullydescribed, and shown in the accompanyin drawings, and the novel features thereof wil be pointed 'out by the appended claims.

. o obtain a full and correct understanding of the details of construction and combinations of features, elements and advantages, reference is to be had to the hereinafter-set- 5 forth description, in connection with the accompanying drawings, wherein-- Figure 1 is a longitudinal vertical section through a car-wheel, showing the journal ortion of the axle with the invention app ied 5 thereto. Fig. 2 is a cross-sectional view on Specification of Letters Patent.

line 2 2 of Fig. 1. Fi 3 is a longitudinal vertical section throug a ear-wheel on line 3 3 of Fig. 2, and Fig. 4 is a view showing a modification of the invention.

Making renewed reference to the acoompanying drawings, wherein similar reference characters indicate the corresponding arts in the several illustrations figures, 1 esignates the body of a car-wheel, having a chainbered portion 2, which is ada ted, if desired, to hold packing to prevent t e waste of the lubricating material. The body of the wheel is provided with a cylindrical bore 3, adapted to receive the journal portion 5 of the axle 6. The rear of the journal portion is provided with an abutment-hub 7 to prevent the wheel from moving inward, as shown clearly in the accompanying drawings. The outer face of the bod portion of the wheel is rovided with a cy indrical inclined bore 8,w ch is of larger diameter than the bore 3 of the wheel, and said cylindrical inclined bore 8 is an extension of the chambered portion 2 and also connects with said chambered portion, so as to allow the oil to find its way from the 8 inclined oil-ducts 9 of the cylindricalshaped cap 10, the end of which fits a cylindrical recess 11, which is provided in the outer portion of the bore 8, as shown clearly in the accompanying drawings; Said cylindrical .cap is provided with inclined oil-ducts 9, as before stated,which are circular in crossseotion, as shown clearly in Fig. 2 of the aceom-, pany drawings. Said cap is also rovided with similar ducts 12 intermediate t e ducts 9, which are of the form of longitudinal recesses. The said ducts 12 open into and connect, as at 13, with thec lindrical bore 14 ot the cap 10. In this way tfie lubricating mate rial also finds its way to the journal portion, as at 15, which portion fits within the bore of said cap, as clearly shown in Figs. 1 and 2 of the accompanying drawings. i

The journal portion of the axle icli fits the cap 10 is provided with a V-shape amiu- 100 lar recess 16, 'which receiges the conicalshaped ends 17 of the set-screws 18, which are inserted throu h the wall of the cap 10, as shown clear] in ig. l of the accompanying drawings. his V-sh aped annular recess not 105 only provides means for receiving the conicalshaped ends 17 of the set-screws for preventing displacement of the cap and wheel, but serves as a reservoir in which a certain amount of oil lodges for the purpose of lubrir 10 2 choose I cating the conical-she ed ends of the setface of the cap is provided with an opening 19 and also a threaded cylindrical recess 20, which is adapted to receive a suitable packing 21 to prevent the oil from being wasted through said opening 19. receivesa lug 22, the ends of whic are conical-shaped in opposite directions, as at 23 and 24, Said p ug is rovided with a suitable check-valve 25, w ereby as the oil-can is inserted. within the end of the plugsaid check-valve will be pushed-Open against the tension of .a suitable spring 26, which will allow the oil to flow through the conical-she. ed hereof the lug 22, after which the'oil will d its w y tot 1e chambered oil portion 27 from whic it will flow through; the ducts 9 and then into the chambered portion 2 of the body portion of the'wheel, as shown clear] in F 1 of the accompanying drawings. he said spring 26 is mounted upon the stem 25 of the valve 25 and also interposed between the valve-disk and across bar 26, which spans the conical-she ed bore of the pin 22. The conical-shaped ends, as at 23 an 24, of the plug 22 are provided for the p seof preventing the plug from moving in ei her direction. Tlhe clonlcslil-shfiped end 23 off tie p ug 22 is ace witiin t e opening19=o .t e outer portibn of the cap, after which suitable parking 21 is placed around said plug over which a suits in packing-nut 28 1s eed, which is provided with screw-thieadsto engage the threads of the cylindrical recess 20 of the cap it), which will prevent ,theplug from moving outward.

From the foregoing description it will be plainly observed that a ver eflicient journalubricating device for wieels is provided which is simple in construction and which ma be manufactured at a very sli ht cost an sold to the trade comparatively ril eapx Hpvingdescribed the invention, what is claimed as new, useful, and novel is 1. A lubricating device comprisih a; cap having an oil-chamber, oil-ducts an a central'opening, a hollow plugfitting in Said opening, which opening is beveled to prevent inner movement of the plug, means to pH:- vent the outer movement of the plug and Said 0 ening 19 means for automatically closing theopening in the plu i 2. A in ricating device comprising a cap having an oil-chamber, oil-ducts and a central opening, a hollow plug fitting in said opening, sald opening having means to prevent inner movement of the plu means to prevent the outer movement of t e plug and a check-valve for the plug.

3. A lubricating device comprising a cap having an oil-chamber and inclined oil-ducts therein, a plug for the end of the cap, provided with means to prevent the inner movement thereof and a packing-nut to prevent the outer movement.

4. A lubricating device comprisin a cap having an oil-chamber and inclined oil-ducts therein, there being an opening in said cap, 'a plug to he received by said opening, means to revent outer movement thereof, there being inclined walls in said opening to prevent the inner movement.

5. In a lubricating device for wheels and axles, a cylindrical cap car ied by the end of the axle and having an oi -chamber and inclined oil-ducts, a oheck-valve-controlled plug for the end of said cap, said axle having ariannular V-shaped roove, thumb-screws carried by the cap and aving V-shaped ends to fit in said annular groove to prevent out ward displacement o the cap there being nieans to pnevent the inner movement of the u l p 6% A lubricating device for wheels and axles, comprisin a wheel, an axle, said axle hav' aacylindrieal hub portion to limit the inwii i movement of the wheel, said wheel having a chambered portion, a cylindrical inclined bore commnnicating with said chambered portion, and a cylindrical recess adjacent to said bore, a cap fitted over the end of the axle and having one end engaging said recess, which cap is provided with an oil-chamher, and inclined oil ducts, a plug fitted in the outer endpf said cap and having its ends conical shaped in opposite directions, a check-valve carried by said plug, a packinggland for said plug, and means to prevent outward movement of the plug.

In'testimony whereof I have hereto affixed my signature in the presence of two witnesses.
