GEORGE FINFROCK AND GEORGE VEESENMEYER, OF CHICAGO, ILLINOIS, ASSIGNORS TO THE FINFROCK & VEESENMEYER PATENT JOURNAL OILER COMPANY, OF SAME PLACE.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 499,186, dated June 6, 1893.

Application filed June 7, 1892. Serial No. 435,859. (No model.)

To .aZZ whom it may concern:

Be it known that we, GEORGE FINFROCK and GEORGE VEESENMEYER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in J ournal- Bearings; and we do hereby 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 thesamet Our invention relates to improvements in journal bearings, and it is more particularly designed as an improvement upon the means for oiling the journal of a shaft or an axle which forms the subject matter of a prior patent issued to us on October 20, 1891,and numbored 461,426.

The object of the present invention is to provide novel means which insure'a continuous lubrication of the parts to reduce the friction and wear, and to return the ,waste oil to the receptacle, thus obviating dripping of the oil and effecting a saving in the quantity of lubricant required to properly supply the j ournal of the axle or shaft.

A further object is to improve the bearing in minor details of construction in order to secure greater simplicity, durability, cheapbearing adapted to contain a limited quantity of oil and arranged wholly within the fixed lubricant-receptacle below the journal bearing proper, said swinging bearing being pivoted at one end, combined with a supply wheel j ournaled in said swinging bearin g and operating in a vertical slot in the lower side of the journal bearing, and a spring in the receptacle, below the swinging bearing, and

having one arm forming the bottom thereof,

which arm rests against the same so as to ele- Figure l is a.vertical longitudinal section through the device, the plane of section being indicated by the dotted line wx of Fig. 2. Fig. 2 is a vertical transverse-section through the bearing and the receptacle on the line yy of Fig. 1. Fig. 3 is a horizontal section on the line m, m, of Fig. 1, looking in the direction indicated by the arrow m. Fig. 4 is a detail sectional view of the pivoted cupbearing.

Like letters denote like parts in allthe figures.

A designates the journal bearing which is divided horizontally so as to form two longitudinal sections B, C, the lower section B haying in its upper edges the longitudinal recesses b which receive the depending flanges c on the upper edges to accurately and closely fit the two sections together. In the journal bearing, at the ends thereon-we provide the annular grooves or recesses d, d, adapted to receive the usual collars provided onthe journal of the axle or shaft (not shown) and between these annular recesses or grooves the sections are lined with any suitable metal, as at D, D.

E is the fixed receptacle or box provided at one end of the journal bearing to contain oil to be supplied by the feed wheel to the journal; and this receptacle lies below and transf which lies outside of the receptacle and communicates with the chamber thereof, to enable the lubricant to be readily deposited in the receptacle without removing the same.

G is the swinging bearing shown by detail in Fig. 4, and also indicated in Figs. 1 and 2. This swinging bearin g consists of the two side plates g, g, suitably shaped and formed to provide the recesses g, g, that are in line with each other to receive the trunnions or ends of the shaft h, of the fiat or disk like supply wheel II. This supply wheel fits partly in the cup-shaped bearing and it is free to turn or rotate therein so as to raise the lubricant and supply the same to the journal bearing; and said supply wheel is further provided with transverse openings h. The lower ends of the plates or sides g, g, of the bearing G are joined by the ends '5, i, which are integral with the sides or plates g, g, and said bearing G is thus left open at top, bottom, and the ends so that the oil can freely enter the same to be taken up by the supply wheel. Said bearing is pivoted in the receptacle by means of the pin or shaft t which passes through the end i of the bearing and which is secured in the walls of the receptacle; and the end i of the bearing has a recess in one edge thereof which recess receives the free end of the upper arm 1 of a compound leaf spring I. Said leaf spring is arranged in the lower part of the receptacle or box E, below the pivoted bearing therein, and the spring is fastened at the bend by means of a rivet or screw j so as to be held securely in place in the receptacle and still leave its members free to act in elevating the cup-bearing. The upper member I of the spring bears or acts against the free end of the pivoted bearing, and said arm of the spring is prevented from becoming displaced or disconnected from the bearing by having its free end fitting in the recess or groove of the end 2" of said bearing, thps holding the parts always in operative po sition.

In the lower half or member B of the bearing A, and in the vertical plane of the receptacle, we provide a vertical transverse slot K in which fits the supply wheel H, the upper part of said wheel projecting above the slot far enough to have the necessary contact with the lower side of the journal to insure the desired rotation of said supply wheel.

The oil supplied by the wheel to the longitudinal opening in the journal bearing is distributed along the journal by means of the ducts or grooves n, 'n, in the lining of the lower member B, which grooves extend in inclined lines longitudinally of the bearing which have the inwardly leading inclines n which open into the vertical slot in the lower section B of the hearing. The upper section 0 of the bearing is also provided with a longitudinalgroove o in its lining, and with a Vertical inlet port 0 bywhich the attendant is enabled to pour oil directly into the hearing, from the upper side of the same.

To insure the return of the oil or lubricant to the receptacle after the same has passed through the bearing, and thus prevent dripping and waste of the lubricant, We provide the return passages P, P, which extend longitudinally of the bearing below the longitudinal journal opening therein. The return passage P extends nearly the entire length of the bearing, that is, from the annular groove d to the vertical slot, and the short longitudinal passage P extends from the other groove d to said slot, whereby the two passages are adapted to convey the waste oil back to the slot and thence to the receptacle.

In operation :The supply wheel is pressed by the spring elevated bearing against the journal, and said wheel is thus rotated by frictional contact with the journal. The wheel carries the lubricant up into the longitudinal j ournal-opening, and the longitudinal grooves distribute the lubricant uniformly along the journal, the oil being deposited into the grooves d, d and from thence pass through the return passages to the receptacle.

We are aware that changes in the form and proportion of parts and details of construction of the devices herein shown and described as an embodiment of our invention can be made without departing from the spirit or sacrificing the advantages thereof, and we therefore reserve the right to make such alterations as fairly fall within the scope of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination with a journal bearing having a vertical feed-slot, and an oil receptacle fixed to said journal bearing below the feed-slot thereof, of a swinging bearing G comprising the spaced connected plates g, g, having the recesses g in their apices and pivoted at one end, by a pin 1?, to the oil receptacle, a feed-wheel H fitted between said plates g, g, of the swinging bearing and having its shaft journaled in the recesses g and the leaf spring I secured in the bottom of the oil receptacle and with one end thereof fitted between the connected ends of the plates g, g, forming the swinging bearing, as and for the purpose described.

In testimony whereof we affix our signatures in presence of two witnesses.

GEORGE FINFROCK. GEORGE VEESENMEYER.
