RDYAL S. HILDRETH, DF SOUTH ADAMS, ASSIGNOR TO HIMSELF AND RUFUS B. RICHMOND, 0F ADAMS, MASSACHUSETTS.

Letters Patent No. 98,655, dated Januar/y 4, 1870.

IMPROVE!) LUBRICATOR.

lill

. il To all whom it 'may concern:

Beit known that I, ROYAL S. HILDRETH, of South Adams, in the county Berkshire, and State of' Massachusetts, have invented a new and useful Improvement in Lnbricators; and I do .hereby declare that the following is a full, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The object of this invention is to furnish Va simple and cheap means for oiling or lubricating journals in all situations; and consists in the use of a spring within the oil-cup, in connection with an oiliug-wire, so arranged that the wire shall be at all times pressed against the journal, in whatever position the oilcup may be placed, as will be hereinafter more fully described.

The accompanying drawing represents a vertical section of the lubricator, as when in use, in 'a vertical position, the journal and journal-box being shown in dottd lines.

Similar letters of reference indicate corresponding parts.

A is the oil-cup, which is made of glass, or of other suitable material, with a metallic collar, B, cemented to the neck, on which collar is fitted a tubular screwcap, C, as seen in the drawing:

I) is an oiling-wire, which passes loosely through the tubular cap, to the innerI end of'wbich there is attached a spiral spring, E.

The spring bears upon the bottom of the cup, and the outer endl of tbe'vyire D bears on the journal.

Tbetube of the cap G is screwed into the box-cap, so that the oil, which flows through the tubeA around the wire, will be conducted by the wire to the journal. The same result is produced when the cup is placed in a horizontal instead of a vertical position, or in any other position, so long asthe oil in the cup rises above the end of the wire.

It will be readily seen that the wire and spring may be so adjustedthat the end of the wire will press constantly against an uneven surface, as, for instance, for oiling a cam; but I design it more especially for journals of upright sbafts,.and for use generally where ordinary lubrication cannotl be applied, or Where they are only partially eiective.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The combination of oil-cup A, collar B, cap C, spring E, and wire I), all arrangedV and fitted together as and for the purpose specied.

R. S. HILDRE'IH.
