SPECIFICATION forming part of Letters Patent No. 399,721, dated March 19, 1889.

Application filed February 3, 1888. Serial No. 262,921. (No model.)

T0 all whom t may concern.-

Beit known that I, WILLIAM W. WORS- WICK, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Journal-Boxes, of which the following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention has for its object an improved form of journal-box containing the following specific points of invention:

First. The use of st-ationary bearings to receive the greater part of the strain of the axlejournal, and thereby relieve the anti-'friction rollers from too great pressure. I have discovered by experience that the great pressure of the car-axle on the rollers, especially its irregular action .and heavy pounding when the car is rounding curves or passing over uneven portions of the track, causes the roller s to fiatten and lose their true cylindrical shape, and as a result they soon cease to rotate and revolve. I therefore sufficiently lighten the pressure on said rollers, so that they do not become iiattened, and yet allow them to receive a pressure sufficient to cause them to rotate, and thus act as lifters of the oil and lubricators of the journal without being in danger of becoming flattened.

Second. I form the inner flange integral with the inner end plate, as it can thus be made more cheaply, and I find that the wear on said flange is so much less than on the iron washer on the front side of the boX that it is not necessary to renew the former as often as the latter. Said flange ,and washer are both formed with their interior faces inclined inwardly from the upper portion of each to a point slightly below the center of the axle-journal, so that at that point they most nearly approach each other, and as the rollers rise in their upward movement they may be forced into parallel planes relative to each other and the axle-journal as they come into bearing or operative position, and thus continue their rotation in plane parallel with the longitudinal plane of the journal.

Referring to the drawings, Figure l is a vertical longitudinal section of my improved journal-box, the axle being shown in eleva'- tion. Fig. 2 is a horizontal section of the same, the axle being omitted. Fig. 3 is a vertical section taken on the dotted line in Fig. l, showing a face view of the flange-ring. Fig. 4 is a side elevation of the iron washer, the top being broken away, showing the brass bearing. Fig. 5 is a perspective view of the brass bearing. i

Ais thej ournal-box, provided with the outer and' inner end plates, respectively, B O, secured to the body of the box by the bolts Z). A Harige-ring, c, is cast integral with the inner plate, O, and inclines from its upper portion inward until a point is reached slightly below the center of the axle-journal D, which fits in the circular openings E of the said j ournal end plates, l5 C. The bearing-chamber F of the box is provided with the steel liningplates f f the former encircling the upper half, the latter encircling the lower half of said chamber. Said plate f is provided at its lower portion with the opening g, surrounded by flange g', which latter flange fits in the opening 7L of the oil-chamber I-I, sew cured to the under side of said box, and thus communication between the axle or bearingchamber and the oil-chamber is established. The said bearing-plates may be inserted and removed in the usual way.

The anti-friction rollers G are formed with round ends and have bearing intermediate of the aXle-journ al and the steel bearing-plates l As has been stated, the iiange-ring C is cast integral with the end plate O, but separate from the end plate B, and secured thereto by bolts 71; is the iron washer j, also formed with its inner face inclined from its upper portion inwardly until a point is reached slightly below the center of the axle-journal. Thus at said point flange-ring c and washer most nearly approach cach other, the distance between them gradually increasing until their upper portions are reached, where they are most widely separated. I make this washer j removable, as it bears a portion of the strain incident to end-thrusts of the axle, and hence Wears much more rapidly than the inner fiange, c. The inner face of the plate B is depressed, and having its outer face, l, seated therein is the rocking plate L, the raised inner face, l, of which iits loosely in the opening in the washer IOO Said plate L receives much of the strain caused by the end-thrusts of the axle and correspondingly relieves other portions of the journal-box.

At the upper portion of the journal-box is the oil-hole m, closed by the cap m', andis so located that when the journal is supplied with oil the plate L is lubricated. The oil-well is useful not only to hold a quantity of oil, but also to furnish a chamber toward which the dirt and dust may gravitate.

The axle -iits loosely within the opening of plate C, and as the car lurches and swings suddenly the oil contained in the chamber is apt to be ejected. To prevent this and to exclude dust as far as possible, I slip a cap, N, suitably bored, over the axle and bolt said cap to the plate C. Awasher, n, is tightly secured to the axle within the chamber N', formed on the inner side of said cap, said chamber being of diameter about equal to that of the bearing-chamber of the axle-box. The diameter of said washer is slightly less than that of said chamber, and the washer is located midway between the inner face of the cap and the outer face of the plate, so that the washer will not collide with either during the end movement of the axle. NVhen the oil is ejected fromthe box, as aforesaid, it strikes the collar and falls into the bottom of the chamber. The accumulation of oil and dust in the bottom of this chamber in time forms a soft packing, and it is found that very little dust enters thejournal-box and no oil escapes therefrom farther than the chamber N.'

In the upper portion of the flange c and washer j, respectively, I secure the keystoneshaped brass bearing-blocks O, and against these the axle-journal has bearing, as the distance from the point of bearing of said blocks and the bearing-plate f is equal to the diameter of the anti-friction rollers. The object of these bearing-blocks is to relieve the antifriction rollers from too great a pressure, and to prevent them from wearing flat or changing from their true cylindrical shape, as undue pressure tends to flatten the said rollers and prevent their rotation. The present contact between the rolls and the axle is sufficient to rotate them, and thus as they revolve around the axle the oil is elevated from the chamber and the axle is lubricated.

Just below the center of the axle I make the distance between the inclined flange .c and washer but little greater than the length of the anti-friction rollers, in order that as the rollers revolve upward they may be forced in parallel planes by said flange and washer, respectively, just as they come into bearing against the box-namely, just as they rise above the horizontal center of said box. From this point upward the horizontal distance between said flange and washer gradually increases. I preferably make the stationary bearing-blocks of brass; but any other suitable metal may be used. Said bearing-blocks may also be increased in number or changed in location without departing from the principle of invention.

The foregoing description and accompanying drawings set forth in detail mechanism in embodiment of my invention. Change may, therefore, be madetherein, provided the principles of construction respectively recited in the following claims are retained and employed.

I therefore particularly point out and distinctly claim as my inventionl. In a journal-box, the combination, with a stationary bearing located within the box anda rotary bearing, the working-faces of said stationary and rotary bearings being located in the same horizontal plane, of aplainfaced journal portion having direct engagement with both said bearings, substantially as set forth.

2. In a journal-box, the combination of an axle journal, stationary bearings located within said journal-box, and against which said axle has bearing at the inner and outer ends, respectively, of said journal-box, and anti-friction roller-bearings located intermediate of said station ary bearings, substantially as set forth.

3. In a journal-box, the combination of iiange and washer located, respectively, at the inner and outer portions of the journal-box and provided with openings, stationary bearings fitting in said openings, and frictionroller bearings located intermediate of said Stationary bearings, substantially as set forth.

4. In a journal-box, the combination of an axle-journal, a dan ge and a washer located, respectively, on opposite sides of the journalbox, the horizontal distance between them being least slightly below the center of said axle-journal, and thence gradually increasing upward, and anti-friction rollers located intermediate of said flange and washer, substantially as set forth.

' 5. In a car journal-box, the combination of the bearing-chamber F, the cap N, secured to the outer face of said bearing-chamber, said cap provided with the chamber N,which communicates with said bearing-chamber, the diameter of said two chambers being substantially equal, the axle-journal D, journaled in said bearing-chamber, and the washer n, rigidly secured to the axle of said journal within.

said chamber N', midway between the outer and inner walls of said chamber and free from engagement with said walls,a clear space being left on eitherside of said washerintermediate of the said respective walls and washer, the diameter of said washer being slightly less than that-of said chamber, substantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this lst day of February, A. D. 1888.
