LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 227,570, dated May 11, 1880.-

Application filed February 20, 1880. Patented in England Ifebruary 27, 1878.

ed over the surface to be oiled and connected therewith by a hollow stem or tube containing a suitable conductor which regulates the flow of the lubricant, and also fil rs or strains The object of our invention is to for fectly oil-tight joint between the reservoir its stem or tube, to prevent loss by breakage and to facilitate refilling and cleaning the res- 2o ervoir by a simple and inexpensive construction of parts.

The figure of the accompanying drawing is a sectional elevation of our improved lubricator.

I 5 A represents a glass reservoir of any convenient size or shape, and B its neck, integral therewith, and constructed with convex sides internally.

represents an annular plug of cork with- 0 in the neck B; D, the ordinary metallic stem or tube which supports the reservoir and conveys the oil to the surface which is to be lubricated; and E, a combined conductor and filter, of a preferred form, composed of a num- 3 her of strands of galvanized wire twisted together, the same filling the interior of the tube D throughout a given portion of its length. Any of the common filtering and flow-controlling fillings may be substituted for the con- 0' ductor and filter E, if desired.

The plug 0 is attached at its lower end to a rigid disk, X, and slides therewith upon the tube D, to which it is tightly fitted. The upper end of the plug engages with a collar, y,

5 attached to the extreme upper end of the tube by upsetting or riveting the latter.

Care should be taken to make the plug of greater length and of a greater diameter at its lower end than the neck B will accommodate, and the collar 3 should be flaring. as shown. Said plug O, in combination with the neck B, forms acheap and very superior coupling between the reservoir A and the tube 1). Being elastic and a non-conductor of heat, it

is not affected by jarring nor by expansion and contraction, like a metallic coupling, and being compressed by the said convex internal \walls of the neck, it readily forms a perfectly oil-tight joint therewith and with the tube within itself, the requisite force being readily applied to the plug through the medium of said rigid disk X, which also supports the plug beneath, and any tendency to displace ment operates, through thetlaring lower end of the neck in one direction and the flaring collar 3 in the other, to expand the plug and preserve its tightness.

In inserting the plug the neck cannot be subjected to strain which would cause fracture, and when it is removed to refill or clean the reservoir it leaves the same free from all attachments.

We do not claim as new aninverted glass reservoir having a detachable tube containing an oil conductor and filter; but

What We claim as new andof ourown invention, and desire to protect by Letters Patent of the United States, is

The improved lubricator consisting of the glass reservoir A, with its neck B, having convex internal walls, the plug O, of elastic material, the tube D, with its filtering and flow-regulating filling E, and the disk X and flaring collar y, as herein specified.

In witness whereof we have signed our names in the presence of two subscribing witnesses.
