Description

Nov. 18, 1930. w. H. COITON LUBRICATING DEVICE Filed Oct. 31, 1924 Patented Nov. 18, 1930 UNITED, STATES T N J Y O FICE WALTER I-IL common, ori cnrcne'o, ILLINOIS LUBRIoerIrie nEvIcE Application filed October 31, 1924. serial no; 747,030.
ther'object isto provide means for augment:
ing radiation of heat from the container and O furthermore, to prevent ,the wasteful flow of lubricant when steam is shut off the chamber to which the device is applied.
Other and further objects andadvantages of the invention'will appear from the followingdescription taken in connection with the accompanying drawings,- in which Fig. 1 is a central vertical section showing the invention; p Fig. 2 is a top or plan view; and
fication of a detail.
The device consists of a body portion 10 provided at its lower end with a securing nipple 11 and an angular portion 12 for the engagement of a wrench for attaching the nipple 'to its support in the usual manner. A dome shaped cap 16 removably secured to the body portionlO forms a closure for the chamber or lubricant container 17.
A tube 13 extendingaxially' through the container 17 is provided with a spring closed valve 14:. The valve is held in operative position and is enclosed in a valve chamber formed by the cap 15 which is threaded to the tube. A hole 26 in cap 15 completes a passage from the tube 13 to the chamber 17 The body portion 10 is preferably provided with radiating ribs 18 for cooling said container. The body portion may, if desired, be
m provided with a pet-cock 19 secured to a passage leading'from' the bottom of chamber 17 for removing the water. of condensation as occasion may require.
The device is shown secured to a steam chest 20 in which numeral 21 designates a steam passage which communicates with tube 13. p
The operation of the device is as follows:
r The chamber 17 being filled with lubricant 0 such as grease, and cap 16 replaced, the de- Fig. 3 is a vertical section showing a modi vice'is-ready--;for service. Steam entering the passage-'21 will pass up tube 13 raising valve 14' and continue through passage 26 into chamber 17. If the container is filled with grease it will immediately melt and become a liquid. When the pressure inchamber 17 equalizes the pressure in the tube the valve will drop and close the passage. Condensation now takes place in chamber 17,'the lubricant being lighter than the water of condensation'will float and be forced into the valve chamber. The recession of temperature and pressure in chamber 17 will again cause the lifting of the valve and a small quantity of lubricant spreading out as a film'on the 3 walls of the tube will pass down the tube at each impulse. Should steam be shut off from the chest 20 the valve 14: will cease its impulse and stay closed, preventing further flow of lubricant until the steam is let on again.
In the modification shown in Fig. 3 the tube 130 in threaded to the body portion 10 and a ball'valve 140 is seated at the throat of the tube. A chamber 22 near the top of the tube is filled with fibrous material such as cotton wick which may be compressed to any desirable degree by a screw 23 having a small passage 24. Tube 130 also is contracted at 25 below chamber 22.
The fibrous material forms a further impediment to the passage of matter through tube 13 which will result in slower but somewhat similar operation of valve 140 to that shown in Fig. 1.
What I claim as my invention and desire b to secure by Letters Patent, is
1. In a lubricating device, in combination, a lubricant'container, a steam chamber, a pasbetween the container and steam cham- )0 her, said passage comprising a tube extending upwardly within said container, a spring pressed valve closing the'upper end of said passage when the pressure within said container and chamber are equalized, said valve being adapted to be moved by the steam pressure to, open said passage when the pressure in saidchamber exceeds that in said container, and a cap within said container threaded ,on the upper end of said tube for enclosing said valve and for positioning the same on the upper end of said passage. 7
2. A lubricating device comprising a container provided with a threaded nipple extending outwardly therefrom and a tube extending upwardly therein, said tube and nipple being provided with a bore, a spring pressed valve for-closing the upper end of said bore, a cap for enclosing said valve, said v cap having an aperture through its side wall,
a closure for said container for enclosing said tube, cap and valve, a pet cock in'communication withthe lower portion of said container, and heat radiat ng ribs on the exterior of said container.
