-.Application filed February y12, 1906. Serial No. 300,791.
To all whom it may concern:
Beit known that I, EDWARD P. BULLARD, Jr., a citizen of the UnitedStates, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Rotary-Table Bearings, of which the following Ais a specification.
v bearing of this kind than has heretofore been produced.
Upon the .accompanying drawings, forming a part of this specification, similar numerals of reference denote like or corresponding parts throughout the several figures, and of whichv Figure 1 shows a perspective view of a portion of the bed or frame of a boring-mill and the table therefor in a raised position to show my improved bearing. Fig. 2 isl a transverse vertical section through a portion of the frame and table shown in Fig. 1. Fig. 3
is a plan view of the bearings of the frame, t
tions in't Referring in detail to the numerals of re erence marked upon the drawings, 5 indicates the base of the A-machine, whichobviously may be Elformed in'accordance with together 'i'th the foil-reservoir and connecthat of any modern boring-mill, vertical lathe, or similar machine-tool. 6 indicates a table the top design of which may likewise be of any preferred construction and driven in the usual way through an annular rack 7, attached to the under side of 'the tablev and engaged and operated through the pinion 8 upon a vertical shaft 9, to which power is communicated throu h a bevel-gear 10, operated from any suita le connection with the driving mechanism of the machine.
17 the 'top surface of which is preferably inclined at an angle with respect to the surface of the table and is adapted to receive the annular inclined engaging bearing 18. upon the under side of the table. The annular engaging surfaces of these bearings are below the surface-line of the oil within the annular pocket, and the bearings being narrow and located Aintermediate ofthe side walls form spaces 19 and 20 on either side to retain the oil, which compartments are connected through the radial oil-channels 21 of the lower bearing. There may obviously. bei
any number of these channels in the face of the lower bearing, which is best adapted to answer the pur ose of lubricating the bearing-surface of t e parts in accordance with the particular class of machine to which the device is applied.
22 representsv a illingecup or reservoir which is suitably connected through the pipe 23 and one of the oil-channels 21 with t annular pocket of the frame to su ply the oil 'i thereto. In practice the top of t e reservoir is slightly above the level of the inner wall 15 of the annular pocket, thus insuring the filling of said pocket with the filling of the reservoir and permitting a slight overflow from said reservoir to the spindle-cup. The transparent openimy 24 in the reservoir readily shows the heigzht of oil covering the bearing and indicates when an additional supply of oil'is required. The oil-reservoir is preferably filled through the top and is provided with a detachable screw-cap 25, which is removed for filling.-
IOO
With a construction as shown it Will be seen that all the Wearing-surfaces are either fully submerged or otherwise amply lubricated with oil. The side edges of the annular bearings intermediate of table and frame are fully covered with oil at all times, and besides by reason of the several oil-filled radial channels in the face of the lower bearing the -under surface of the upper bearing is constantly being exposed to the oil, which serves to cool the bearings thoroughly, besides lubricate this intermediate surface.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1.' The combination of a self-lubricating table-bearing, comprising a frame having an annular straight inclined bearing therein, an annular oil-pocket upon the inside adjoining the bearing and extendedfbelow the surface of the same, radial channels extending from the said annular pocket throughrthe top surface of said straight inclined bearing, and a table having a straight inclined portion to rotate upon the bearing of the frame.
2. table-bearing for machine-tools, comprising a frame having yan annular' inclined bearing, and an annular pocket on each side l of and extended ybelow the surface of such bearing radial ch'annels'extending from said pockets through the inclined wearing-surface of the bearing, a table rotatably mounted upon said bearingof the frame, and an oilreservoir-connected with the oil-pockets and `surface of the-lower bearing, and oil-channels extending across the surface of said lower bearing and connected with both said oilspaces. f
4. In a table-bearing for machine-tooflathe combination of a frame having a central s indle-bearing, a straightinclined annular ta lebearing, an annular pocket on each side of said table-bearing, radial channels extending through the table-bearing and connected l with both said annular pockets and a spindled table rotatably mo'unted in said spindlebearing and upon said table-bearing.
5.' A. table-bearing for machine-tools, comprising a base having a central spindle-bearing, and an annular straight inclined tablebearing, radial channels in the face of the tai ble-bearing, an annular pocket on both the with inclosing side walls the 'outer wall of the pocket-being higher than the inner one to insure the overflow of oil passing on the spindlebearing connected oil-reservoirs located on a level with the inner Wall of the pocket and a ing.
`table mounted to rotate upon the said bear- 6. A table-bearing for machine-tools, cornl prising a frame having a central spindle-bearing therein, an annular pocket exterior of said hole, and a raisedannular bearing Within the pocket, a spindled table rotatably mounted in the bearings, transverse inclined oil-channels through the face of the tablebearing adapted to lubricate the under inclined bearing-surface ofthe table, a connected oil-reservoir to ill the pocket-of the frame, and said frame being adapted to permit overiiow upon the spindle-bearing.
7. In a self-lubricating table and spindle-` bearing for machine-tools, the combination oi a frame having a central ,spindle-hole therein, an annular pocket, an annular bearing intermediate the width 'of the pocket `iorming oil-spaces Ion each side of the bearing, oil-channels extending across the bearing, a spindled table mounted upon the bearing and journaled in the hole of the frame,
oil-space to. the other, a table having an annular bearing extended into the pocket to engage the frame-bearing, 'and a spindle iitted y to the hole of the frame, an annular? pocket surrounding the spindle and adapted to receive the overflow from the oil-pocket and lubrieate the spindle, and an oil-reservoir to supply the oil to said pocket.
