TO ALL WH'OM IT MAY CONGERN:

Be it known that we, THOMAS R. ROBINSON, and ROYAL EJ ONES, of Providence, in, the county of Providence,

in the State of Rhode Island, have invented a new and useful improvement in Lubricating "".Bolsters` for spinning y l frames, and Lubricator for other machinery, forthe purpose voi' regulating the flow of oil; andweldollxereby` declare that the following is a full and exact description thereof, reference being hadtoithe accom'panying``` f and to the letters of reference marked thereon.

drawings,

Figure 1 is a perspective view. Figure 2 is a sectional view of the bolster. I l l y l Figure 3 is a perspective and sectional view of the cap or press-screw used `ori` the ,lubricatcr i'orI` other y ss-screw used on the bolster, andthe cap or press-screw the only difference between the cap Or pre used on the lubricatcr for other machinery, being that in the latter no spindle hole is drilled..`

The nature of our invention consists in regulating the flow of oil ina bolsterandIIlubricator for `other y, machinery, by the use oi' a press-screw, which compresses an absorbent placed inthe bottomi of andannulari chamber, as shown in the drawings, (fig. 2,) and as hereafter described.` I i i i I i To enable others skilled in the art to malte and use our invention, w tion and operation. I, I I I I I I A is an annular chamber for holding the supply of oil. B is the absorbent placedin the bottorxuof the chamber lA, and is compressed to regulate the flow of Ioil. C is the cap or pressfscrew, the" cylinder o ich extends into 'the chamber A, and presses-upon the absorbent B. This cylinder also forms `,theiinn i i i chamber A, and is surrounded by the oil.,` DD are the holes in the top of ,the press-screw C, fora oil to the chamber Ar 'E E is the chamberin which the spindle revolves, and into which the `oil i'lows.` used asa bolster, ahole must'necessarily bedrilled in the press-screw C, as shown in iig.\2,`for,'1eceiving y spindle; but when used for lubricating other journal bearings than those of spindles,"the cylinder` of` the pr sscrew islmade solidthat is, no I spindle passage is drilled, as shown in fig. 3.. I "I i I I A i y F The operation is as follows: The absorbent is placed in the bottom of the chamber A, and theiprcss-screw then screwed down upon it. The cha'mber IA is then filled with oil, through the holes D D. `lfThe1 dow oflfoilIis regulated by th d according to the amount ofloil required. i The e press-screw, more or less compression being use oil will continually pass through the absorbantjB into the passage E, thence to the journal bearing.` The absorb ent can be so vcompresse drop` an hour,II

d that the ilow of oil will be at the rate of from one drop a second toIone Sto. The advantages of our bolster and lubricator,

machinery e will proceed to describethe constr`11c` l over others .now in use, are the regulation `of"`the owof Ioil,

the saving of both time and oil, and the ease with which the absorbent can be removed when it becomes clogged or gummed.

ini as our invention, and desire to secure by Letters vPatent, is-

What we cla y A lubricating bolster, having chamber A, cap C, withy or without central perfcratiomE, `and absorbent, `1?,

substantially as described for the purpose set forth. I `1, y y R ,I A
