LUBRICATOR Specification of Letters Patent. I Patented s e pt, 1'7, I918,

Application filed October 19, 1917. Serial No. 197,420.

To all whom it may concern:

Be it known that I, OLOF SwANsoN, a citizen of the United States, and a resident of Denver, Colorado, have invented a certain new and useful Improvement in Lubricators, of which the following is a full, clear, and exact description.

.My invention is an improvement in lubricators and relates in particular to certain improvements adapted particularly to flange lubricators of the type illustrated and claimed in my Patent No. 1,229,822, issued June 12, 1917. The principal objects of my invention are the provision of a lubricator having a feed regulator (as distinguished from a regulating valve) controlled and operated by vibration transmitted thereto on account of the lateral movement of the wheels with respect to the engine or car frame; to associate with such feed regulator a feed controlling valve automatically operated by the same vibration and constructed to positively close and shut off feed of the lubricant when the engine is standing still; and to provide certain other improvements in detail of construction and simplicity of parts which will later appear from this specification;

In the single sheet.- of drawings accompanying this application and forming a part hereof- Figure 1 is a partial, central, vertical section and partial side elevation illustrating my device and the manner of supporting and utilizing the same; and

Fig. 2 is a partialhorizontal section and partial plan view showing details of the mounting of my device.

Referring to the drawings, in which like characters of reference indicate like parts in the several views, let 1 designate the lubricant container which is preferably of cylindrical shape with a reduced lower extremity 2, also of cylindrical shape. A spring pressed cover 3 pivoted on the pin 4:, held in ears 5, closes the upper end of the container and a plug 6 is threaded into the lower end of the container portion 2, to provide a readily accessible means for cleaning. In one side wall of the reduced lower portion 2 of the container there is formed a port 7 which communicates with a downwardly inclined formed integrally with the container by casting the entire device.

The lower end of the chamber 8 is intechamber 8 preferably riorly threaded as indicated in the drawings and a lubricant distributing nozzle is screwed therein. This nozzle is preferably a chilled casting having a cylindrical opening or bore cored throughout its length, said bore being of greater diameter toward the surface 10 which is to engage the flange 11 of the Wheel IV. Within the bore in the nozzle 9 I place a pin 12, this pin being of considerably less diameter than the lower 'end of the bore but of only slightly less diameter than the upper or inner portion of the bore. A flattened head 13 serves to prevent the pin 12 from falling out of its socket.

At one side of the reduced lower portion 2 of the lubricant container I locate a heating chamber in as close proximity as possible to the lubricant regulator and controlling parts. This chamber 14 is provided with a pipe 15 leading thereto from the exhaust of the air pump or like source to furnish expanded steam to the chamber 14. Here the steam condenses, delivering heat at moderate temperature to the container adjacent thereto and maintaining the lubricant fluid even in the coldest weather. The water of condensation accumulates in the lower portion of the chamber until it rises high enough .to run out the downwardly inclined escape 15,a limited excess of water from which may trickle past the pin 16, which substantially but not quite fills the bore of an opening in the plug 17 which closes the lower end of the escape 15. This construction provides a very restricted opening out of the chamber 14, thus preventing the rapid escape of steam; and the pin 16, which is free to travel a short distance in its bore, prevents the accumulation of dirt to clog the restricted opening. A screw plug 18 closes the cleaning port in the chamber 14.

In the upper end of the reduced portion 2 of the lubricant container there is screwed a valve cage 20, closed at its lower end save for a restricted port 21- and provided on its lower face with a hexagonal wrench engaging face 22. The cage 20 is screwed up in its socket until its shoulder 33 engages a similar shoulder formed on the container; the plug is now home with its lower face well above the port 7. Around the upper reduced end of the cage 20 and resting on a shoulder 23 thereon, there is mounted a screen 24 through which the oil passes in leaving the main reservoir in the container.

A split sleeve 26 surrounds the container 1 atyang appreciable; distance above the C6Il3- ter of gravity of the device and this sleeve carries a trunnion 27. bearing 28' sup'-* ports the trunnion in such manner that the same is freetdturntherein; and thebea r"- ing 28 is carried a sleeve 29 and stands withiit's; axis 'atfright anglesto the aXisof 'said" sleeve.

If it is found that on account of excessive knocking in the journal boxes the nozzle 9 ever flies out so far as to ride on the rim of the flange 11 this can be readily remedied by mounting an adjustable, rigid finger either on the bracket 32 or on some part of the frame, which shall overlie the nozzle 9 and prevent its moving a sufticientdistance radially of the wheel to engage the rim of the flange.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a lubricator, a nozzle having a 1011 gitudinal bore therethrough, said bore having a relatively large diameter section adjacent its outer end, and a relatively small diameter section adjacent its inner end, a pin within said bore, said pin and the small diameter section of said bore being so propoi-tioned that the pin approximately stops the flow of lubricant through the small bore section while the pin is quiet but induces and regulates a substantial flow therethrough when said pin is in vibration, and means for supplying a. lubricant to the inner end of said nozzle.

2. A lubricator comprising a lubricant container, at discharge nozzle connected therewith, a vibration actuated valve controlling feed from said container to said nozzle and a vibration actuated feed regulator in said nozzle.

3. lubricator comprising a lubricant container having a bottom sloping toward a centrally located port, a ball normally closing said port but adapted to be displaced therefrom by vibration, a nozzle in communication with said port, and a vibration actuated feed regulator in said nozzle.

4. A lubricator comprising a lubricant container having a bottom sloping toward a centrally located port, a ball normally olosing said port but adapted to be displaced therefrom by vibration, a nozzle in communication with said port, said nozzle having a longitudinal bore, and a pin Within said bore, said bore and pin being so proportioned that the pin approximately stops the flow of lubricant through the bore while the pin'is quiet but induces and regulates a substantial flow therethrough when said pin is in vibration.

pin is quiet but induces and r gulates a sub-- stantial flow therethrough when said pin is in vibration.

6. In a lubricator, a heating chamber, means for supplying steam thereto, a water discharge port leading from said heating chamber, and a pinfree tovibrate in said port.
