To ALL WHoM rr MAY ooNonRN:

Be it known that vI, JOHN C. FISH, of the townand county of Barnstable, and State of ll/Iassachusetts,y

have invented a new andimproved Device for Oiling Rotating Bodies; and I do hereby declare that the following, taken'in connection with the drawings which accompany and formpart of this'specication', is a description of my invention sufficient to enable those skilled inthe art to practise it.

l This inventionl illustrate'herein in itsl application to the hubs of carriage-wheels, though it may be applied in asimilar 'nianner and with similar results to other bodies rotating or moving on or about shafts, axles, or pins. In the drawings l Y l I 4Fi ure shows in sectional elevation a. wheel for a Wa on or carriafre, havin a lied to its hub m g g e g PP Y y improved oiling device.

This consists of a reservoir,.a, provided with a tube, c, extending through it and secured therein, said tube having two openings from its side into the body of the reservoir, an upper one at d, and a lower one at c. The top and bottoni of..this tube c are open, the bottom connecting with a tube,f, set into the hub g and the box it of the wheel, and the top being provided with the threads of a nut. Closely fitting in the tube c is a tube, e, closed at its top,- and provided with 'screiv-th`reads, which, kttingthe nntltbreads at the top of tube c, canse tube t' to rise and fall therein whenever tube is rotated. In the sides of tube z' are three openings, two of which, nino, correspond with the openings e in the tube e when the tube t' is-raised suliicientlyin tube c for tbedppeiopening o in' tube z' to communicate with the' atmosphere. In the tube between its openings n and'o, prefer to locate a plug orv partition for a. purpose tojbe hereafter referred to. In the reservoir there is a l removable screw-plug, 70, serving to close the orifice through which the supply of oil is delivered to the'reservoir.

rEhe-tube z' is provided with means 'oy which it can be rotatechand thus raised and lloweie'ed in tube c by the employment of a wrench or screw-driver. If the reservoir is filled orl partly iilled with oil, and the parts are in the position shown in the drawing, it will be obvious that oil must gravitate upon the axle m from the reservoir, as air will flow through the'openin'gv, tube z', openings o, and d, to supply the place ofthe oil flowing upon the surface to be lubricated. But if the tube z' is sciewed down into tube c, so that the opening v no longer admits the passage of air, the flow of oil will be stopped, as the oil will not run out of the reservoir and producen vacuum therein. The'oil will also be prevented from ilowing, because the passages 1t and e will no longer open into each other, the solid metalof the tube i closing the passage e.. The purpose of the plug or--partitio'n"beforc v mentioned as inA the tube z', is to act as the piston of a syringe in forcing the oil before it upon the siiiface to be lubricated, as the tnbe t' is'moved inwards into tube c. The joint between' the tube c in the reservoir and the tubef in the hub may be made, as in lig. 1, by a Washer of suitable lyielding material, or by a thimblc, as Seen in fig. 2, the thiinble enclosing the adjacent ends ofc-the tubes c mdf. In applying this oiling device to carriage-wheels, the size, shape, and locution of the reservoir may be varied to suit circumstances, and in some instances it maybe wholly embedded in the wood of the hub. An amount of lubricating material can bc easily contained in the reservoirs of a set. of wheels suilicient to last a carriage in constant use for several weeks; no oil is lost or wasted, neatness is preserved, andthe oiling is easily effected by thc simple operationvof rotating the tubos z', instead of by propping up cach end of each axle and removing the wheels therefrom-iu thc usual way. y

I claim a lubricating apparatus, constructed of a reservoir in which is located the tube @,provided with openings as described, and with a perforated movable tubo, t', operating substontiallyus described.

JOHN C. FISH.
