TO ALL WH'OM IT MAY CONCERN:

Be it known that I, ALEXANDER MILLAR, of Edinburgh, Scotland, residing at Roxbury, in the county of Norfolk, and State of Massachusetts, have-invented au Improved Oiler and Filler'gand I do hereby declare that Ythe following, taken in Yconnection with the drawings whichaceompany and form part of this specification, is a description of my invention suicient to enable those skilled in the art to practise it.

The invention relates to the construction of vessels or cans lfor oiling machinery, iilling lamps, Ste.; and consists in constructing the can with a false bottoru,'in which is a. valve, and from which leads a cylinder'provided with a piston, the space `under the false bottom constituting a shallow charging-chamber `from which leads the eduction pipe, the piston-rod being connectedto a wire, so that the'piston and oiler maybe operated thereby when'the oiler is not directly held in and operated by the hand.

The object of my invention is to enable a fixed amount of luid to be ejected from the can, so as to avoid danger of overiiowing the vessel to be filled, and pf wasting the oil, and also to enable shafting and other mechanism to `be readily oiled without necessity of introducing the hand and arm into proximity with such mechanism. i

I am aware of the construction of the oiler patented by John King Von the 10th of July, 1866, but such patented oiler has several defects which are obviated in inyinvention.

The drawing represents a central section of an oiler and filler embodying my invention.

a denotes the can or vessel to containthe lubricant or other luid; b the bottom lthereof, at a little distance above which is a parallel false bottom, c, the space between constituting a shallow chamber, d, from which the fluid is ejected through the discharge pipe e, which opens out-.of one side of the chamber, as seen in the drawing. The false bottom c is provided with a valve, f, whichopens and closes afiluid-passage, g, -leading from the main reservoir h into thecharging-chamber d. Extending up from the chamber d, and opening freely thereinto, is a cylinder, z', provided with lu. piston", lc, on the end of a piston-rod, l, which extends vup through the can, and has at its top a thumb-piece, ni, for operating the piston by hand, ivliile connected thereto is a wire, n, extending along a long handle, o, made of suitable length to allow the can to be carried by its means to mechanism beyondthe reach of the artisan, as will be readily understood. 'The piston-rod isprovided with a spring, p, for press ing the piston upto the top of the cylinderLand the piston is preferably made with cup-packing, as seen in the drawing. the mouth a conical strainer, s, which shall prevent any foreign matters (which would clog the ejecting tube) from entering the` reservoir in charging it with fluid.

The operation of thc oiler is as follows: The reservoir being charged with oil through the tep q, if the piston c be now pressed down the expansion oi' the spring will driy'el it up when thc rod lis released, and the uid will rush through the opening g into the chamber d to supply the vacuum caused by ascent of piston k, the valvef falling away from the opening g bythe pressure of thc liquidabovc.v The pistonibeing then forced down, the fluid willbc pressed up into the discharge tube e. and ejected from its point, the valve f' closing and preventing uid from being forced back into the reservoir, and` causing ai'ixedfquaptitytobe ejectedupon the mechanism to be oiled, or into the vessel to be iilled, in accordance with 'the degree "of descent' of Vthe piston.

Without the false bottom c and shallow chamber d, and the valve f, -vi'twould, not. be jti'racticai 'to 'e`il`ecttl1is,` as

The mouth q of the vessel is covered by a cap, r, in the usual manner, but I prefer to place within the lluid would not be ejected from the tube with certainty,` but would,"lmuch of'it', simply dbw back intoltbe cylinder if `the ejecting tube were connected directly to such cylinderjf l 1 I claim, in combination with the reservoir, ejecting pipe, cylinder, and pistonthe' julseil bottom 2, gslillw` chamber d, and valvef, constructed and arranged to operate substantially asset forth,
