FRANK 1 LANDIS, OF WAYNESBORO, PENNSYLVANIA.

SELF-OILING JUURNAL-BEARING.

Application filed August 20, 1904, Serial N 0. 221,491.

T 0 all whom it may concern:

Be it known that I, FRANK F. LANDIS, a citizen of the United States, residing at lVaynesboro, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Self-Oiling Journal-Bearings, of which the following is a specification.

My said invention consists in an improved construction of self-oiling journal bearings, whereby a, bearing of such cha actor is provided which will be certain in its operation under all conditions, all as will be hereinafter more fully described and claimed.

iteferring to the accompanying drawings which are made a part hereof and on which similar reference letters indicate similar parts, Figure l is a view of one of my imn'oved journal bearings partly in elevation and partly in central longitudinal section, Fig. 2 a transverse section looking in the di rection imliiated by the arrows from the dotted line f2-9 in Fig. 1, Fig. 3 a cross section looking in the direction indicated by the arrows from the dotted line 3-3 in Fig. 1 omitting the parts B and B and, F 4 an end. elevation.

in said drawings,the portions marked A represent the main shell of the bearing, B a yoke and binder in which. said shell is mounted, and C a ring carrying the oiling device. The shell A is substantially of a well known form containing a bearing A for the journal or shaft, which bearing is cast in piece with said shell and with a central opening A which divides the bearing proper into two parts, which are joined by the oilchamber A cast on the lower side of said shell A, which is thus a one-piece castin The central portion a of the shell is en larged to form a ring surrounding the center of the shell and said ring is turned to semispherical form on its outside surface. Both parts of the hearing A are lined with Babbitt-metal or other suitable metal A and a groove a is formed in the upper side of said bearings extending longitudinally thereof from the inner ends of the two parts nearly to their outer ends. A circumferential groove a is also formed near the ends of the bearings and a perforation c leads from the lower side thereof into the oil chamber A A tube or perforation A is formed on one side of the shell leading into the oil chamber through which the oil is supplied thereto. Said tube is closed by a cap a.

Specification of Letters Patent.

Renewed December 11, 1908. Serial No. 467,079.

A screw-threaded opening a, closed by a screw plug a, is formed in the lower side of the oil chamber through which it may be cleaned.

The yoke and binder B is formed to fit snugly around the enlarged central ring or portion a of the shell and is connected therewith by a screw B which extends through a screw threaded perforation in the lower side of said yoke, its point being formed conical and ei'lgaging a shallow perforation in the under side of said shell, as shown. By this means any longitudinal or rotary movement of said shell is prevented while it is permitted to adjust itself to any variation in the alinement of the journal. The top of said yoke is preferably formed open and connected by a cap piece B secured thereto by bolts or set-screws Z). Said cap also covers the opening in the top of the enlarged portion of the shell. A leather or other suitable gasketb is interposed between the edges of said shell and said cap for the purpose of making the joints between them oiltight.

The ring C is split upon one side and has a transverse bolt 0 extending through ears formed at each side of the slit therein, by which the two parts may be drawn together, and the ring clamped to the shaft or journal. An arm of paddle 0 is inserted in the slit in said ring and held by means of said bolts, or carried in any preferred manner. Said arm is of the form shown in Fig. 1, being adapted to extend into the oilchamber nearly to the bottom and enter the body of lubricant therein and carry the same around, and by centrifugal force throw said lubricant into the open space between the ends of the bearings A and flood said space as the shaft or journal revolves, the lubricant running into the longitudinal groove al along the top of the bearings and keeping said bearings thoroughly lubricated.

In assembling the parts, the ring C is placedin the central opening in the hearing before cap 13 is put in place, and said bearing then slid upon the shaft or journaled to the position desired. hen in said position the screw 0 is tightened to securely clamp said ring 0, with its projecting arm 0', upon said shaft or journal. The cap B with the gasket 6 is then put into place. The ring O rotates with the shaft and through the arm 0 operates to carry the lubricant by centrifugal force into the upper part of the central chamber, from which it passes through the grooves a along the surface of the journal and thus keeps the bearings thoroughly lubricated. A principal object of said ring C and the wide end bearings A is to prevent any longitudinal movement of said journal or shaft. It being firmly clamped to the shaft its sides will abut against the inner adjacent wide ends A of said bearings and thus secure this result. The Babbitt-metal lining is widened at this part to cover the ends of bearing parts A and provide a wide bearing surface A" for the sides of said ring C. By this arrangement an oiler is provided which will not become inoperative by reason of the congealing of the oil or lubricant in the oil chamber as the arm 0 attached to ring C is held positively to the shaft and must revolve therewith and keep said lubricant agitated.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent is 1. A self-oiling journal bearing comprising a casing having the bearings therein, and formed with a central opening which divides said bearings, a yoke for supporting said casing, a conical pin engaging a conical recess forming the engagement between the two parts, a removable cap for the opening in said casing which also serves to connect the ends of the yoke, and oil distributing means mounted upon the shaft between the two parts of the bearing, substantially as set forth.

2. A self-oiling journal bearing comprising a casing, bearings formed in said casing, said casing being formed with an opening that divides said bearings, and its central portion on the under side being formed with a semi-spherical contour, a yoke provided with a conical pointed screw for supporting said casing, the point of said screw being adapted to engage with a suitable recess in the central portion of said casing, the journal, the oil distributing means carried thereby, and the cover for said opening in said casing also adapted to connectthe ends of the yoke, substantially as set forth.

3. In a journal bearing, the combination of the shell having an enlarged central portion, a yoke or binder with an open side supporting said shell. said shell being formed with a recess, a cap for closing said recess and connecting the sides of said yoke or binder, a divided bearing formed in said shell, a ring rigidly secured to. the journa between the bearing parts, and an arm projecting from said ring, substantially as set forth.

=1. In a self-oiling journal bearing, the combination of the shell formed with an oil chamber in its lower side, a ournal bearing in each end of said shell, there being an opening in the top of said shell into the space between said journal bearings, a yoke for supporting said shell provided with a removable cap adapted to close said opening, the shaft or journal mounted in said bearings, a ring rigidly secured thereon between said bearings. and a projection on said ring, substantially as set forth.

5. In a self-oiling journal bearing, the combination, of the shell formed with a central portion of enlarged diameter and an opening leading through the top of said onlarged portion of said shell, a ournal bear ing in each end of said shell, a yoke engaging with the underside of said shell and a removable cap adapted to close said opening and to connect the sides of the yoke, all substantially as set forth.

(5. In a self-oiling journal bearing, the combination of the shell formed with an opening in its top and having a bearing in each end, a yoke supporting said shell at its center, a removable cap adapted to close the opening in said shell, there being a longitudinal groove formed in the top of each bearing and circumferential groove near their ends with a perforation leading therefrom into the oil chamber, substantially as set forth.

7. In a self-oiling journal bearing, the combination of the body cast in one piece with a bearing, which bearing is divided by an annular opening, said body being in piece with both ends of said bearing, the journal or shaft mounted therein, and a ring secured to said journal in said opening, the sides of which provide end thrust hearings to prevent lateral movement of said journal, said ring having projection, for the purpose set forth.

In witness whereof, I have hereunto set my hand and seal at Washington, D. (1, this twenty-fifth day of July, A. D. nineteen hundred and four.
