To all whom it may concern.-

Beit known that I, JEAN BAPTISTE FoNDU, asubject of the King of Belgium, residing at Vilvorde, in Belgium, have invented certain new and useful Improvements in Lubricators, (for which I have obtained patents in France, No. 179,011, dated October 13, 1886; in Belgium,No. 72,621, dated April 3, 1886; in England, No. 15,068, dated November 19, 1886, and No. 8,108, dated June 6, 1887; in Austria-Hungary, No. 22,920, dated June 2, 1888, and in Italy, No. 23,588, dated June 30, 1888;) and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The present invention has for its object to provide a lubrcator applicable to connectingrods, pulleys, and other rotating or oscillating parts, whereby the grease or lubricant is caused to pass through an opening in a feed passage or duct located above the level of the grease or lubricant when the lubricator is stationary and horizontal.

The invention consists in certain novel details of construction and combinations and arrangements of parts to be now described, and pointed out particularly in the appended claims.

In the accompanying drawings, Figure 1 represents a vertical section through a lubricator as applied to a pitman or connectingrod. Fig. 2 is a top plan of the same. Fig. 3 is a section on the line w, Fig. 1. Figs. 4 and 5 are vertical sections of lubricators adapted for application to any class of rotating or reciprocating machinery.

Similar letters of reference in the several figures indicate the same parts.

It will be understood that in the use of the present lubricator the parts to be lubricated have a motion in which the direction of movement is changed-as, for instance, the reciprocatory movement of a connecting-rod or the rotary movement of a pulley-by which movement the grease or lubricant is thrown into the opening of a feed tube or duct in such manner that a small portion is caught and carried to the journal-bearing. The shape of the body of the'lubricator itself, as well as.

the manner of attaching it to the moving part, is immaterial.

In the drawings, Fig. 1; the bodylettered A is shown as if formed on a base either constituting a part of or adapted to be secured directly on a connecting-rod, while in Figs. 11'

and 5 it is shown somewhat of the shape of an ordinary lubricator and adapted to be secured in position in the ordinary manner.

From the bottom of the receptacle a tube B or similar discharge-duct extends upward to a convenient heightand at a point near the top lateralopenings b are provided leading into this duct. In the preferred construction these lateral openings b are in an extension C of the duct, formed on the top orl cover and registering with the duct vB, which construction of grease is regulated at will and absolutely by means of a screw E working through the top and past the lateral openings to close them to a greater or less extent. The screw itself is locked and held in adjusted position by a setnut F of usual construction.

In the form shown in Fig. 1 the entire domeshaped top is formed by t-he cover, which is removably held inplace by set-screws; but it is obvious that the cover needs be of such size as is desired for lling and cleaning purposes only. Thus in Figs. 4 and 5 the cover is simply a large screw-plug, and the walls of the receptacle proper are drawnin, froming the curved or dome-shaped top. In fact it is .preferable to employ a removable screw-top in every instance, and I have therefore shown such construction applied also to the structure shown in Fig. 1. Y

The efficiency of the device in some situa- Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a lubricator having a curved top or upper portion, of the discharge duct or tube having lateral entranceopenings at or near the top of the curved portion and with no communication with the cupI atV the bottom, and a regulator for said openings working through the top of the lubricator, substantially as described.

2. In a lubricator for moving parts, the com-A bination, with the receptacle, the removable top having the curved inner surface, and the screw Working through said top, of the discharge duct or tube having lateral entrance- 3o openings at or near the top of the curved portion and in position to be closed by the screw and with no communication with the cup at the bottom, substantially as described.

3. In alubricator for moving parts, the combination, with the receptacle and discharge duct or tube having no communication with the cup at the bottom, of the top having the curved inner surface with the tube depending from its highest part, registering with the discharge duct or tube and having the lateral openings for the entry of lubricant at or near the top of the curved portion, substantially as described.

4. In a lubricator for moving parts, the combination, with the receptacle and discharge duct or tube, of the top having the curved inner surface with the tube depending from its highest part, registering with the discharge duct or tube and having the lateral openings for theentry of lubricant, and the screw working through said top and past the openings to close or vary the size of the same, substantial] y as described.

In witness whereof I have hereunto set my hand in presence of two Witnesses.

JEAN BAPTISTE FONDU.
