MPROVEMENT IN SELF-LUBRIGATIN G JOURNAL-BOX.

TO ALL WHOM IT MAY CONCERN:

- Be it known Vthat L SAMUEL FISH BOND, of Worcester, in the county of Worcester, and State of Massa.- chusetts, have invented a certain neu' and useful Improvement on Self-Lubricating Journal-Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification', and in which- Figure 1 represents a plan of a self-lubricating,journal-box constructed according to my improvc1uent,'\vith thejournal of a shaft arranged for rotation therein and Figure 2, a transverse section of the saine through the line :u s; in g,V Il.

My improvement relates tothat description of self-lubricating journal-boxes in n'hicu the oil or lubricating material is contained in the loiver or box part of said devices, and is drawn out on to thejournal by the rotation of the latter, While the surplus of er any ex-tra oil so extracted is by the same motion returned or worked back to the reservoir. '.lherehave been numerousLiournaleboxes for accomplishing this end, but my invention essentially'diifers frein them both in ci ,istruction and principle of action, and the nature of my invention consists in constructing the box part, prelembly on either side of the journal, with oil reservoirs or chambers open at the ntop, which admits of the same being cast clear of sand, and of being readily cleaned froin'time to time, and establishing lower communications for supply of the journal ivith oil, that' may'y be fed thereto or drawn from either reservoir by the rotation of the journal, through the intervention of wicks or fibrous feeders, while the interior upper edgesof the reservoirs are arranged and constructed to act as Scrapers or clearers for shaving or cutting off surplus oil throughout, it may be, the width of the `journal, and returning itV to the reservoirs.

Referringtto the accompanying drawing, A represents a revolving shaft or spindle, the journal a of which is arranged to run in a journal-box, B, to which C the gland, that may be provided with air apertures, b, for feeding in the oil and lgiving the necessary atmospheric pressure thereon to produce' the required flow. The journal-box B is constructed with oil chambers or reservoirs, D, open at the top, andarranged along either side of thejournal a, preferably for nearly 'the whole length of the latter. This lconstruction admits of the oil reservoirs being formed clear of sand in casting the box, which it is difficult or impossible to do where the reservoir is of a close character and cored out from beneath; also` admits of said oil chambers being made cleaner generally, and of being cleared out with facility from time to time, as occasion may require. Under certain circumstances there may bcibut one chamber D, say on the side of thejournal which occupies a front or forward position relatively to the run of the shaft in its ordinary direction, but the arrangementlof such chamberson opposite sides of Vthe journal is preferred, more particularly where the journal is required to be lubricated in opposite directionsof travel, and the principle of action being the'same, the description here given lwill be confined to a double arrangement of reservoirs, as represented in the drawing. These chambers D are provided at or -near their bottoms, on their inner sides, with apertures, c, that forni vents to supply the ljournal with oil, und which may have wicks or fibrons'feeders projecting through them from the interior of the reservoirs to and against the journal. The upper -inner edges (Z of said chambers areV made sharp or thin, so that oil drawn by the rotary motion of the shaft out of the supply apertures from either or both chambers will be evenly distributed over the journal, and any surplus orex tra quantity be cut or-:cleared off, more especially by the edge d, which occupies a front position-relatively to the direction .in travel of ithejo'urnah andwill he returned to the reservoir or reservoirs, thus restricting the lubrication to thin or licht strata, and providing a long and free return, it may be for the Whole length4 of thejourna-l, for the surplusoil, thereby avoiding waste or scattering at the ends of the journal, which in avery rapid motion of the shaft it has heretofore been diflcult to prevent, even clear end return passages failing to accomplishthe saine.

What I claim as my invention, and desire to secure by Letters` Patent,ris Y A self-lubricating journal-box, constructed substantially as described, with a chamber or chambers forming oil reservoirs along either side of the journal, also provided 'with lower supply apertures and their upper inner edges made to form Scrapers or clcarers for removing surplus oil and to return it to the reservoirs, essentially as herein set forth.
