Application April 29, 1940, Serial No. 332,327

4 Claims. (61. 137-68) This invention relates to devices for dispensing liquid to a reservoir whereby a predetermined level may be maintained in the reservoir at all times.

Specifically the invention has for its object the provision of mechanism, in which lubricant is automatically fed to the crankcase of an automotive engine to retain a specified fixed level of oil in the crank case.

Another object of the invention is the provision of means whereby an adequate supply of oil is available to the feeding mechanism.

Another object is the provision of an attachment for a crank case in which a container for oil is provided, a part of the container coasting with the attachment to initially open the container and thereafter to intermittently release oil therefrom.

Another object is the provision of a device as an attachment for a crank case in which, a support is located adjacent the crank case, a reservoir mounted on the support, the reservoir and the support having coacting parts providing a valve seat and means for securing the reservoir to the support.

It is further an object of the invention to improve the quality and enhance the utility of devices of that class to which the present invention appertains.

Other objects will present themselves as the description proceeds, it being also understood that changes may be made within the scope of what is claimed without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the drawings:

Figure 1 is a sectional view of the device taken on line I-I of Figure 2.

Figure 2 is a view partially in elevation and partially in section, the view being taken at right angles to the showing in Figure 1.

Figure 3 is a detail sectional view of a portion of a container used in connection with the invention.

Figure 4 is a sectional View of a modification.

Referring to the drawings by character of reference the numeral I designates the crank case of an internal combustion engine, in which it is desirable to maintain a fixed level of oil. Connected to the crank case in any approved manner is an inlet tube 2. Secured to the tube 2 as at 3 is a collar 4 forming a part of a bowl 5. A cover 5 for the bowl has a pan I formed integrally therewith or otherwise, the cover is secured to the bowl as shown at 8 and has a depression 9 formed in its upper surface.

A sheet metal can or reservoir I0 is mounted in the pan I. The can may be of any size,

. adaptable to the space available, preferably of several quarts capacity.

A valve seat I I is formed on the bottom of the can, the seat being of circular formation. The center of the seat is inwardly depressed to form a conical guide I2 for a purpose to be presently disclosed. The container It] is provided with a filling neck and cap l3 at the top directly over the valve seat.

A post I4 is interposed between the cap I3 and :bottom of the container, the lower end of the post is shaped to conform to the profile of the valve seat II and rest therein, the upper end of the member I4 is engaged by the cap before the cap reaches its seat on the neck of the can.

A saddle I5, having legs I6, is placed astride the can at the neck portion thereof. The legs I6 have ratchet teeth H which engage corresponding teeth I8 formed in the rim of the pan 7. When the saddle is brought to rest on the can and the teeth Il engage the teeth I8, the cap I3 may be screwed down thereby forcing the valve seat into the depression 9 and securing the can detachably to the supporting structure I. At the same time, should there be any distortion of the valve seat on the can, during the interval between packing the can and its installation on the motor, the pressure exerted by the post i on the relatively thin flexible metal of the container will reshape the valve seat and provide a perfect seating surface for the valve.

A valve stem I9 is slidably mounted in guides 28 and 2| on the bowl 5. The stem carries intermediate its ends a valve 22 adapted to seat against the valve seat I I. A float 23 is connected in the usual manner to the valve stem I9. The lower end of the valve stem moves in a socket 24 in the guide 2|, downward movement being limited by a shoulder 25 in the socket.

The upper end of the stem has a piercing point 26. When the can is introduced into the holder I the point is guided to the apex of the cone I2 piercing the same as shown at 21, thus providing for discharge of oil into the bowl 5, from whence it is carried to the crank case I by way of the tube 2. When the oil reaches the proper level the float rises and closes the valve 22, cutting off the flow until the proper level falLs when more oil is admitted.

It will be observed the point 26 is larger than the stem It on which it is mounted thereby providing ample space around the stem for a flow of oil.

As shown the post I is of tubular form and is provided interiorly with a float 28, having an indicating stem 29, which may be pointed as shown, wherewith to pierce the cap I3 when the can of oil is put into service.

The stem 29 may be indexed as shown at 38 and will show at all times'the remaining quantity of oil in the container.

The member 1 is slotted at 3| permitting the oil to flow to the interior thereof.

It will also be noted the post 1 serves as a baflle to prevent surge of oil in the container hammering on top of the valve 22, possibly causing improper opening of the valve.

In the modification shown in Figure 4 the same numerals with the sufiix a have been used to designate similar parts in the preferred form. As shown the stem 32 extends through the float 33 and is secured thereto, a collar 34 under the float rests on the bowl to support the piercing point 26 as the container is punctured.

In installing the dispenser let it be understood that a crank case is equipped with the component parts of the device exclusive of the container, and that the container comes to the user with the valve seat and guide cone already formed and as shown in Figure 3. The container having been previously filled and sealed. The container is prepared for installation by removing the cap l3 and puncturing the same for reception of the stem 29. The post 1 is then inserted through the can neck and the can placed on the holder with the cone l2 over the point 26. Downward pressure is applied to the 'can through the instrumentality of the saddle l5, the teeth ll of the legs l6 clicking over the teeth It! on the pan, thereby seating the valve seat H in the depression 9. The perforated cap is next placed over the stem 29 and screwed down on the can neck into engagement with the top of the post 1 seating the bottom of the post as hereinbefore specified.

What is claimed is:

1. A dispensing device for liquids, comprising a support, a penetrable container carried by the support, a piercing member movably mounted on the support, the piercing member and the support having parts which coact to hold said member in position to form an outlet in the container when the container is placed on the support, a

valve carried by said member and controlling the outlet, and float-actuated means connected to said member, and moving the valve to and from closed position with respect to the outlet.

2. A dispensing device for liquids, constructed as set forth in claim 1, in combination with a movable inlet closure for the container, a post inter-posed between the closure and the part of the container in which the outlet is located, and responding to a tightening of the closure to distort said part of the container downwardly and hold the container engaged with the support, against downward movement, and releasable means holding the container on the support against upward movement, whereby said downward displacement may occur.

3. A dispensing device for liquids constructed as set forth in claim 1, in combination with a movable inlet closure for the container, a tubular post interposed between the closure and the part of the container in which the outlet is located, the post having an opening for admission of fluid to the interior of the post, the post encasing the outlet and providing a baflie to prevent undesirable surge of liquid through the outlet, the post responding to a tightening of the closure to distort said part of the container downwardly and hold the container engaged with the support against downward movement and releasable means holding the container on the support against upward movement whereby said downward displacement may occur.

4. A dispensing device for liquids constructed as set forth in claim 1, in combination with a movable inlet closure for the container, a tubular post interposed between the closure and the part of the container in which the outlet is located, the post having an opening for admission of fluid to the interior of the post, the post encasing the outlet and providing a bafiie to prevent undesirable surge of liquid through the outlet, the post responding to a tightening of the closure to distort said part of the container downwardly and hold the container engaged with the support against downward movement, releasable means holding the container on the support against upward movement whereby said downward displacement may occur, a float carried by the post and guided thereby, and a stem on the float and extending without the container whereby remaining contents of the container is indicated.
