Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed May 21, 1904. Serial No. 209,040.

To all/ lull/077D it may concern:

Be it known that I, BURTON R. STARE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Journals, of which the following is a specification.

My invention relates particularly to means for retaining oil in and excluding dust from journal-boxes at the inner ends thereof; and my primary object is to provide more efiicient and desirable means for accomplishing said purposes than any heretofore known.

The invention is illustrated in the accompanying drawings, in which- Figure 1 represents a broken vertical longitudinal section of a journal and journal-box equipped with my improvements, the section being taken as indicated at line 1 of Fig. 5; Fig. 2, a section of the detached dust-guard;

Fig. 3, an enlarged broken section of the dust guard, taken as indicated at line 8 of Fig. 6; Fig. 4, a similar section showing the dustguard collapsed, as when in the dust-guard cavity of the journal-box; Fig. 5, a section taken as indicated at line 5 of Fig. 1; Fig. 6, an outer face view of the improved dustguard; Fig. 7, an inner face view of the outer plate of the dust-guard, and Fig. 8, an inner face view of the inner plate of the dust-guard.

In the preferred construction, A represents a journal-box, B a journal, and C a dustguard confined in a cavity or slot (0 at the inner end of the journal-box.

The inner end of the journal-box has a journal-opening a, which is intersectedby the dust-guard cavity in the usual manner. The outer wall a of the cavity a is equipped on its inner surface with an annular boss a having a milled surface (0*, provided with annular oil-grooves a. The wall of the opening in the outer wall a is beveled at its lower portion, as shown at a. The inner end of the journal-box is of sufficient width to allow spaces between the side portions of the annular boss and the side walls of the journal-box,

as shown in Fig. 5. This permits the boss to be readily milled and insures a close joint with thedust-guard. The opening in the inner wall of the guard-cavity is cut lower than the opening in the outer wall, as will be understood by observing the relative heights of the points a and a in Fig. 1.

The dust-guard comprises an outer plate 0,

having a circular perforation 0' and an annular boss 0 at the inner surface of the plate, an inner plate 0 provided with an opening 0*, receiving the boss 0 screws 0 connecting the plates near the four corners thereof, and coilsprings 0, confined between the plates and encircling the screws. The plate 0 is provided near the four corners thereof and on the inner surface of the plate with bosses 0 surrounded by annular channels 0 and affording sockets for the corresponding ends of the springs 0".

The bosses are perforated to receive the screws 0 and the perforations are countersunk at their outer ends to receive the heads of the screws, as shownin Fig. 3. The plate 0 is provided with corresponding sockets 0 for the springs and With threaded perforations for the screws 0". The screws are turned in to the proper distance and then riveted, as shown in Fig. 3. The wall of the journalreceiving perforation c of the plate 0 is provided at its side and top portions with fillings of Babbitt metal 0 and the wall is provided with continuous circumferential grooves 0 The plate 0 is provided at its inner surface, near the four corners thereof, with lugs 0 whose inner surfaces project flush with the inner surface of the annular boss 0 At the lugs 0 the outer surface of the plate 0 is provided with depressions 0 The inner surface of the boss (0 of the journal-box is milled, as stated above, and the outer surface of the plate 0 is milled, so that a close joint is provided. In addition the annular grooves 06' become filled with oil and act as packing-rings to prevent passage of oil or dust. The bore of the plate 0 snugly receives the shoulder of thejournal, as shown in Fig. 1, and the annular grooves o receive oil, which prevents the egress of oil and the ingress of dust. To secure a true surface at the outer face of the outer plate 0, the plate is first secured upon the bed of a planer with the outer surface down, and the inner surfaces of the lugs 0 and the annular boss 0 are planed. The plate is then turned over and clamped at the depressions 0 and the outer surface of the plate planed. The plates are preliminarily placed together with the lugs c passing into corresponding marginal recesses 0 in the plate 0, and the screw-receiving holes in the two plates are simultaneously bored. The construction insures the proper relation of the plates when the parts are assembled and facilitates the operation of assembling the parts. The inner surface of the plate 0 is recessed at its bottom portion, as indicated at 0 to enable the return of oil from the dust-guard cavity a to the interior of the journal-box.

hen the parts of the dust-guard are assembled, the plates are normally separated by the springs to such an extent that the dust-guard is considerably thicker than the space which receives it when in working position. When the guard is forced into position, the springs are compressed, the guard being collapsed, or rendered thinner, as shown in Fig. 4. The springs are sufliciently strong to exert quite a high pressure, preferably more than one hundred pounds, so that the outer plate of the dust-guard will be forced firmly against the annular boss a". It now will be understood that when oil is thrown against the dust-guard from thejournal-box, as in rounding a curve. the liquid-pressure acts with the springs to hold the plate 0 firmly seated against the boss with which the outer wall of the dust-guard cavity is equipped. Moreover, inasmuch as the inner wall of the dust-guard cavity is cut lower than the outer wall, the source of oil from the inside of the dust-guard will not rise as high as the top of the lower portion of the outer retaining-wall. Furthermore, the bevel surface a, will serve to prevent water from entering the journal-box and causing the lighter oil to escape from the journal-box. As stated above, the bevel surface 0, also tends to prevent sand or dust from entering the journalboX.

I have shown the journal-box provided with a boss (Z at the upper portion of the dust-guard cavity, and this boss has its top surface planed and surmounted with a flanged cap or cover CZ, which is firmly secured in place by screws (Z It is usually desirable to insert a block of wood above the dust-guard and below the cap (Z', although none is shown in the drawings. The purpose of providing the antifrictionbearings 0 at the upper and side portions of the packing-ring is to prevent undue wear at the points which are most subjected thereto owing to the starting and stopping of trains and to the jolting action which occurs when the trains are running. The springs o are practically effective to relieve the journal from the weight of the dust-guard, and the upper bearing of Babbitt metal is an additional precaution to prevent undue wearing.

Changes in minor details of construction within the spirit of my invention may be made. Hence no undue limitation should be understood from the foregoing detailed de scription.

What I regard as new, and desire to secure by Letters Patent, is-
