#@EnsoN ADJUSTABLE LUBRICATOR.
Patented Dec. 19, 1876.

JACOB EDSON, OF BOSTON, MASSAOHUSETTS.
v IMPROVEMENT IN ADJUSTABLE LUBRICATRS.
Specification forming-part of 'Letters Patent No. 135,392, dated Decemberr19, 1876; application tiled November eo, 1876.
' of this specification. l
My invention relates to improvements in adjustable lubricators, and is especially adapted for containing lard, grease, heavy oils, or lubricating compounds that will not tlow out through thejlower ortfice without additional pressure, although my inventionimay also be used for lighter oils, in the ordinary way.
. My invention consists of a case or receptacle for the lubricating compound or oil, which 'receptacle isiprovided with an internal scrc'wthread, and is provided in its lower end with an opening, through which the lubricating material is fed to the journal or bearing, Ste.
The oil-receptacle is covered in its upper endby means of a screw-threaded cover, fitting into the internal screw-thread'of the oil-case, by which arrangement the said cover can be screwed down upon the lubricating compound contained in the receptacle, so as to force it out through the lower opening to' the journal, bearing, Src., in the proportion required. In addition to this adjustable arrangement of the screw-threaded cover, itis provided with an elastic or yielding follower, fitting closely, but so as to be free to play up and down, in the recess of the cover. The said yielding follower vis held in its proper relative position in the` cover by means of a central bolt or pin, the upper end .of which is screwed into the upper end of the cover. Behind the said yielding follower is located a suitable spring, by which arrangement the follower will yield upward when the cover is screwed down upon the lubricating material, and as the latter is consumed, the follower will automatically be forced downward upon the lubricating inaterial, and thus force it out to the journal bearing, &c., for a day, or more er less, withlcompressed will valso serve as an elastic cushion, for the purpose of automatically forcing the yielding cover upon the lubricating ma; terial as it is fed to the journal, bearing, &c'.`, in addition to the expansive force of the spring aforesaid.
On the accompanying drawings, Figure'l l represents a si`de elevation of my invention. Fig. 2 represents a central longitudinal section, and Fig. 3 represents a plan View of the same. l
Similar letters refer to similar parts wherever they occu-r on the dier'ent parts of the drawings. l
a represents the case or receptacle for the lubricating material, provided with an internal screwthread, b, as shown, and having an opening, c, inits lower end, and a suitable screw-threaded shank, or similar device, by means of which the lubricator can easily' be secured to the journal, bearing, 8vo., for which it is to be used. rlrepresents the cover, having an external screw-thread, e, fitting into the internal screw-thread b in the case a. The coverd is provided in its extreme upper end with a suitable handle, f, by which it is operg represents the yielding or elastic follower, fitting closely, but with freedom to move up and down, in the annular recess or air-chamber h above the said follower. i represents the pin or bolt by which the follower is kept in its properposition, and on which it is guided during its motion up and down in the .recess h. Above the follower g is located, around the pin i, an Aexpansive spring, la, the upper end of 'which rests against the ppperterminus of the air-chamber h, as shown in Fig. 2; The upper end of the pin o'r bolt 11 is screwedinto a screw-threaded part in the upper portion of the cover d, as shown.
The lower. part of the air-chamber his shown cylindrical in form, its upper part being shown conical or tapering; and I wish to state that I do not wish to confine myself to this particular shape andform, as the same may be carried out in any suitable and well-known manner vwithout departing from 'the spirit of my invention.
Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1. A lubricator *consisting -of a. case vor receptacle having an internal screwthread, in combination with an adjustable screw-threaded cover, as and for the purpose set forth .and
described.
