LUBRIGATOR.

Application filed May 22, 1919,

To all whom t may concern:

Be it known that I, SAMUEL J. SHARP, a citizen of the United States of America, and resident of Wheeling, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Lubricators, of which the following is a specification. j

This invention relates broadly to lubricators, and more specically to a self-acting, or automatic, oiler for journal bearings.

The primary object of the invention is to provide an extremely simple, inexpensive and eicient lubricator which, while generally applicable to the moving parts of machinery requiring lubrication, is designed particularly for use on the journal bearings of the steam-heated cylinder driers employed in textile and paper mills.

As is well known, a high temperature must be maintained in the cylinder driers of textile and paper mill machinery in order that the same shall properly perform their functions, and this inevitably results in such a degree of heat being imparted to the journal bearings of such cylinders that reliable and eiicient lubrication of the bearings becomes a matter of prime importance. Further, it is not only essential that the feeding of the lubricant shall be continuous while the journal is in motion, but also that the feeding shall cease during the time that the journal is at rest, both for husbanding the supply and for preventing waste lubricant from flowing over the ends of the cylinders into contact with surfaces which will be engaged by the'cloth or paper to theJ in-r jury of the latter. y

It is al purpose of the present invention to supply a device by whichy provision is made for the proper lubrication of the journal bearings referred to in the manner hereinbefore indicated as essential.

A further object is to provide a lubricator the application of which to, and the removal of which from, a journal lbearing of any ordinary type is the work of an instant, and which has a construction that renders its replenishment when occasion requires and with any desired form of lubricant ak task that can be accomplished with facility.

A still further object is to provide a device of the character mentioned embodying a container which is separated interiorly by a division wall into two compartments, of

which one is a reservoir for the lubricant and the other is a receptacle for water resulting from the condensation of steam which may escape into the container past the wick-like feeder.

With these and other objects in view, the invention resides in the structural features which will hereinafter be exemplified, reference being had to the accompanying drawings, in Which- Figure 1 is a side elevation of the invention, illustrating its application to a journal bearing;

Fig. 2 is a longitudinal section of the invention with the lid or cover thereof upraised; and- Fig. 3 is a top plan view of the same with the wick removed. j'

Referring to said drawings, l indicates a box-like container the under side of one end of which is prefer-ably curved, as shown at 2, to approximate the curvature of the upper part of the bearing, as 3, with which it is to be associated, adapting it for conformably seating upon such bearing, as shown in Fig. 1. Formed on or carried by the under side of the container adjacent to that end which is reduced in depth by the provision of the curved bottom 2 is a vertically depending stem l which is adapted to seat more or less vloosely within the usual bore or oiler-opening 5 provided in the top of the bearing for anchoring said container in place. Through seating of said stem in the hole 5, as aforesaid, the deviceis rendered Anot only self-supporting, or anchored, in its operative position, but also readily applicable and removable as occasion may require. Fitted closely in and protruding slightly from the lower end of a vertical bore 6 whichl rleads outward through said stem 4 from the interior of the container is one end of a wick 7 which may be of any preferred form and material adapted to conduct a lubricant by capillary action. Said wick has its opposite end disposed within the lowermost part of the container so that it will continue to function as a feeder until either the reservoir has been emptied of its contents or the lubricant has become congealed, or approaches a solid form, to the extent that it can not be conducted by capil lary attraction-that is, -to the extent that capillarity ceases. l l

In this connection it is to be noted that 'tion of its under side arcuately curved to adapt it for conformably seating upon the top of a journal bearing, a stem depending vertically from said arcuately curved p0rtion of the container and adapted for seating in the oiler-hole of the bearing whereby said container is anchored in place, said stem having a passage leading therethrough from the interior of the container, a wick disposed within said container and having an end fitted in said passage, and a screw directed into the embraced end of the wick whereby the latter may be expanded within said passage for diminishing the rate of flow of the lubricant therethrough.

7. A lubricator for journal bearings, comprising a lubricant container having its under side shaped to conform to the eX- terior of the bearing, adapting it for resting directly upon the latter, a stem depending vertically from the under side of said container and adapted to seat within the oilerhole of the bearing for anchoring said container with respect to said bearing, said stem having a passage leading therethrough from the interior of said container, a wick disposed within said container and having an end fitted within said passage, and means separating the interior of said container into two compartments, said means being disposed slightly rearward with respect to the location of said passage.

8. A lubricator for journal bearings, comprising a lubricant container having its under side shaped to conform to the eX- terior of the bearing, adapting it for resting directly upon the latter, a stem depending vertically from the under side of said container and adapted to seat within the oilerhole of the bearing for anchoring said container with respect to said bearing, said stem having a passage leading therethrough from the interior of said container, awick disposed within said container and having an end fitted within said passage, and a partition wall located adjacent to and rearward of the position occupied by said passage whereby the lubricant is prevented from owing to a point whence it may drain directly through said passage.

9. A lubricator for journal bearings, comprising a lubricant container having its under side shaped to conform to the exterior of the bearing, adapting it for resting di rectly upon the latter, a stem depending vertically from the under side of said container and adapted to seat within the Oilerhole of the bearing for anchoring said container with respect to said bearing, said stem having a passage leading therethrough from the interior of said container, a wick disposed within said container and having an end fitted within said passage, and a partition wall located adjacent to and rearward of the position occupied by said passage whereby the interior of the container is divided into a water receptacle and a reservoir for the lubricant, the former having said passage leading therefrom.

In testimony whereof, I aix my signature in presence of two subscribing wit- SAMUEL J. SHARP.
