Cla-ims. (Cl. 221-39) This invention relates to an air-vent oiler, and the principle of the invention can be applied to all kinds of oil cans.

An object of the invention is the -provisionof simple novel and ecient means for supplying air to the spout of an oiler whereby the oil will flow freely through the spout when the oiler is in operation.

Another object of the invention is to provide a workable device to prevent back-flow of oil through the air pipe to the outer surface of the can and to eliminate any air vent in the oiler cap, in order to keep the outer surface of the can free from oil.

A still further object of the invention is to provide a workable device for control of oil from the spout by stopping the air supply at point of intake,

Another object of the invention is the A-provision of novel and eilcient valve means as a unitary part of an air tube arranged'in the oiler.

A still further object of the invention is the construction of a novel and eilicient valve device on the air tube of an oiler, the valve of the device being protected Ypractically completely from contact with the oil, whereby the valve will not stick like an exposed ball valve would do.

With the foregoing and other objects in View, my invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims. s

In the drawing: Y l

Figure 1 is a View in elevation of an oiler, showing part broken away for the purpose tof disclosing the interior structure f the oiler.

Figure 2 is a sectional view taken on line 2-'-2, Figure 1 and looking in the directionY of the arrows.

Figure 3 is an enlarged Vertical sectional view of the upper part Aof the air tube, showing particularly the valve device thereof.

Figure 4 is a view similar to Figure 3 with the exception that this view shows a valve device in an open or invertedposition. s

Figure 5 is a sectional view taken on line 5--5, Figure 3 and looking in the direction of the arrows.

Referring to the drawing by numerals, I designates the container while 2 is the spout; A ller'S is'provided having a closed cap 4.

In the container I and spout 2 is positioned an air tube 5, which communicates at its lower end 6 with the outer atmosphere. This tube is securely fastened in vposition upon the container. The air tube 5 comprises the primary section 'l extending up into spout 2, and upon the upper or inner end of section I is an enlarged auxiliary section 8. For securing the two sections of the air tube 5 together a novel lock 9 is provided. This lock 9 comprises I a socket it (Fig. 5) formed in the primary section l and a registering detent lI formed in the auxiliary section 8, whereby the sections are securely fastened together.

The outer end ofthe auxiliary section 8 is reduced, presenting a small aperture lI2 for the air to pass freely through, but aiiording a relatively small opening for any oil to attempt to enter the auxiliary section 8. A transverse stop pin I3 is placed within the auxiliary section 8 for the purpose hereinafter specified. A solid cylindrical Valve I is slidably mounted in the auxiliary section 8, this valve being pointed'on its ends. The inner pointed end rests upon the valve seat l5 constituted by the inner extreme end of the primary section 1. When the oiler is in its normal'position (Figs. '1 and 3) the valve I4 will be resting upon itsseat I5, but when the oiler is inverted, for discharging oil, the upper or outer end of the cylindrical valve IG will be resting against the pin I3 as shown in Figure 4., whereby the outer air will readily pass in the air `tube and be discharged out of the end I2 insuring of free'flo'w of oil out of spout 2.

The solid cylindrical valve I4 will immediately seat (Fig. 3) when the-oiler is Vmoved to an uprightposition, thus closing the air tube 5 and retaining what air is inthe auxiliary section 8 around it and preventing the oil from owing into the air tube. 'Ihus it will be seen that by entirely enclosing the valve I4 it will not stick like an-exposed ball valve would do, and further the instantaneous seating of the valve on its seat I5 causes an air-seal around the entire valve within itsl Vsolid casing or sectional, whereby backflow of oil is prevented-at the discharge end {2,'which is `a decided improvement and of great importance .and advantage.

The air vent 5 runs up into the spout 2 above the level of the oil inthe can. The spout 2 at such place is considerably larger than the small end of the spout where the oil ows out. .When the 'spout 2V of the can is turned down for the oil tol flow out, unless airis admitted into the spout on the can, oil will be'prevented from flowing from'th'e :end ofthe spout 2. When the operator desires to use the can, he can turn the spout down and the needle valve I4 slides down through force of gravity and strikes the bar I3. This allows the Valve seat to be opened at I and this permits air to flow past said valve seat and around the needle valve and out the spout. As air is thus introduced into the spout the atmospheric pressure in the can is overcome and the oil will ow through from the end of the spout.

Besides relieving the atmospheric pressure the invention will obviate the back flow of oil through the air vent to the outside of the can, which condition obtains with reference to the cans commonly in use. The engineer's gloves soon become saturated with oil and some of the oil is wasted.

Another reason for inserting the air vent into the spout is this: Where the air vent opens merely into the top of the body of the can, oil rushes into the large end of the spout and the action of the air introduced lower down in the can is too slow. The oil being generally fairly heavy, the result has been that the average locomotive engineer cuts a piece o of the smaller end of the spout, so that the oil will flow faster. When this is done, there is a great deal of oil wasted, because the oil ows out at times much faster than is necessary, and there being such a large quantity of oil going out the spoutrwhen the can is turned upright, some of the oil runs down on the outside of the spout and down on the body of the can itself.

Still another reason for my novel device is that' in the type of oilers in use at present, which, of course, has an air vent, the Valve mechanism becomes so loose that oil works out of the body of the can around the valve adjustment device.

To summarize, the air is introduced in the spout through an air vent or intake, so that it will be near to the small end of the spout where the oil goes down, thus affording quicker action. The air is not introduced to mix with the oil, but to relieve the amospheric condition caused by pouring oil from the can. Further, my novel device places the end of the air vent above the oil level, so that the oil can ow back to the inside of the can when the oiler is not in use, and it stops the flow of oil back through the vair outlet to the outside of the can.

Therefore, it will be seen that I have provided a novel and efficient construction which Will prevent back-flow of oil throughrthe air tube 5, while at the same time insuring of plenty'fresh air being discharged into the spout, resulting in free discharge of oil from the oiler when it is in use. My novel construction also insures of a clean and tidy oiler with no oil leaking onto the` outer surface of the container and the c spout thereof. Y

The pin i3 allows of sufficient sliding movement of the valve I4 to insure positive action thereof. The weight of the cylindricalA solid valve I4 is suicient to cause it tovpromptly seat as in Figure 3 or` promptly open as shown-in Fig-- ure 4, insuring at all times of a free flow of fresh air to the spout when the oiler is in'operation.

In those types of oil cans in which they are operated by ordinarily pressing on'V the Abottom thereof, if my invention is applied to such cans, the air supplied thereto will be so positive as to eliminatethe necessity ofsuch pressure! Y While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawing, certain .minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.
