'7 Claims.

My invention relates to dispensers and is for use in opening and dispensing liquid from sealed cans.

The object of the invention is to provide a device of this class which is new, novel, practical and of utility; which will allow the handling of liquid sold'in sealed cans without the usual spillage; which will assure delivery of full measure from the can; which will adequately open the can at one end for drainage and at the opposite end for air, thus assuring fast drainage; which will open the can from the bottom, thus preventing the possibility of mixing dust and dirt, which may have accumulated on the top of the can, with the contents of the can as it drains; and which will be economical in use because of its durability; and, which will be eiiicient in accomplishing all the purposes for which it is intended.

Present devices of this class do not allow easy dispensing of the oil to all types of cars; some do not provide air holes in the can for fast drainage of the oil, others provide air holes and drainage holes in the same end of the cans; nor do they dispense the oil without dripping it on parts of the car. My invention eliminates these disadvantages of present dispensers.

With these and other objects in view as will more fully appear hereinbelow, my invention consists in the construction, novel features, and combination of parts hereinafter more fully described, pointed out in the claims hereto appended, and illustrated in the accompanying twosheet drawing, of which,

Like characters of reference parts in all the figures.

It is understood that various changes in the form, proportion, size, shape, weight, material and other. details of construction, within the scope of my invention may be resorted to without departing from the spirit or broad principle of my invention and without sacrificing any of the advantages thereof; and it is also understood that the drawings are to be interpreted as being illustrative and not restrictive.

The inventive idea involved is capable of receiving a variety of mechanical expressions one of which, for the purpose of illustrating the invention, is shown in the accompanying drawings wherein:--

Numeral l designates a hollow body, its opposite ends cylindrical, and its central portion semicylindrical, leaving one-half of itscentral portion open to receive a can 2. The inside diameter of this body is just slightly larger than an ordinary one'quart oil can, and the opening is of a height to easily {admit an ordinary one quart oil can.

Inside thelower end of the body 1 is attached by screws 3, a base reservoir 4; its upper end grooved to receive an annular resilient seat 5, of a size to accommodate the end of an ordinary quart can 2, which seals tightly between the lower wall of the body I and the wall of the base reservoir 4, preventing the liquid from seeping between the two.

The interior of the base reservoir 4 is cup-like in shape and completely closes'the lower cylindrical end of the body I. Extending through the wall of the base reservoir 4, and the body I, is a hollow cylindrical housing 6, the interior bore of which is larger near its outer end. The interior boreof the housing 6 is threaded at its outer end to receive a packing nut I. The packing nut 1 and thehousing 6 are axially alined and'act as a journal for a hollow cylindrical oil spout 8, the upper portion of which is at right angles to its lower portion, and in normal position extends vertically'along the side of the body I. The extreme lower end of the spout 8 extends beyond the inner end of the housing 6 and communicates with the base reservoir'4 and the body I, allowing oil to pass freely from the base reservoir 4 through the spout 8 when the outer end of the spout is rotated to a position lower than its inner end. To prevent end play in the journal the inner end of the spout 8 is fitted tightly with a cylindrical collar 9, which is held rigidly in place on the spout by a set screw l0 designate like through its wall. Made integral with the collar I0 is a sharp cutting blade II, the position of which can be adjusted on the spout by loosening the screw ID. The end of the blade II moves in an are when the upper end of the spout is moved, and is adapted to cut a large hole I4 in the bottom of a can 2, as shown in Fig. 7, when the lower end of the can is held in position on the seat 5, by means which will be later described. A stud l2 screwed into the interior wall of the base reservoir 4 limits the movement and and prevents dulling of the blade II.

Outside of the body I is a vertical hollow handle I3, extending from the upper cylindrical portion of the body I to its lower cylindrical portion, aflixed to the body by short cylindrical extensions l5 and I6.

' Inside the upper cylindrical end of the body I is a hollow cylindrical plunger I'I, having only its upper end closed. An upstanding stud I8 is rigidly attached to the closed end of the plunger near its center. The upper end of the stud is outside the body I and is horizontally bored to act as a bearing for an axle I9 the outer ends of which are journaled' in perforations intermediate its ends in two opposed flanges of a rocker arm 20. One end of therocker arm 20 is pivotally mounted on a flange 2|, which is integral with the upper end of the body I, and which is located at a point opposite the handle I3. The upper end of the flange 2I forms a horizontal bearing for an axle 22, the outer ends of which are journaled in two centrally perforated flanges located at one end of the arm 20. The opposite end of the rocker arm is similarly pivotally mounted as shown at 23, on the upper end of a rod 24, at a point in alinement with the extended axis of the handle I3. This explains the mounting of the plunger IT on the inside of the upper end of the body I. It will be evident that the plunger is free to move upward or downward inside the body, such movement being controlled by movement of the end of the rocker arm which is attached to the rod 24.

The rod 24 is housed by the handle I3. Two coiled springs 25 and 26 are also housed by the handle I3' and surround the rod 24 inside the handle. With the plunger I! in a. raisedposition and the rod 24 in a corresponding raised position, the rod is of a length to permit approximately two inches downward movement before its lower end contacts the closed bottom of the handle I3. Midway between the ends of the handle I3 a collar 21 is carried by the rod 24. The position of this collar on the rod is vertically adjustable by means of a set screw carried by the collar 21. The collar '21 acts as a seat for the upper end of spring 26 and for the lower end of Spring 25." Movement of the rod downward is partially retarded by the force of spring 26 whose lower end is seated on the. bottom of the handle I3. Movement of the rod upward is likewise retarded by the spring 25, the upper end of which is seated against the end of a centrally bored plug 28 which screws into the upper end of the handle I3 and acts as a guide for the vertical movement of the rod 24.

The rod 24 is adapted to' be locked in stationary position at any point in its vertical travel by means of'a lock plate 29, the inner end of which is pivotally mounted on the extension I5 as shown at 30, in a manner similar to the pivotal mounting of the rocker arm 20, as shown at 23. The plate 29 has a perforation near its center large enough to barely allow the rod. 24 to slide therethrough when the plate is at right angles to the axis of the rod. A coiled spring 3i is located intermediate. the rod 24 and the pivotal mounting 30, its upper end seated on the plate 29 around a stud 32, made integral with the plate. The lower end of the spring seats around a stud 33, made integral with the extension I5. The spring 3| is normally compressed and tends to push the outer end of the plate 29 upward, and to keep the plate from a position at right angle to the axis of the rod 24. When the plate is in a position other than at right angles to the axis of the rod, the edge of the perforation in the plate frictionally grips the upper portion of the rod 24, and prevents its vertical movement. A series of notches 34 are provided in the upper end of the rod 24 to increase this grip of the plate on the rod. The plate 29 at its outer end is enlarged and bent downward to form a thumb trigger 35, adjacent the upper end of the handle. Pressure on the trigger brings the plate into aposition at right angles to the rod 24 and allows vertical movement of the rod through the'perforation in the plate.

' A pin 35a is slidably mounted through a perforation in the top of the plunger I'I near its outer wall. The lower end of the pin 35a is conical in shape and is larger in circumference than the central portion of the pin. In normal position the conical end is inside the'plunger, in proximity to the top of a. can 2 in position on the seat 5. At its upper end the pin is threaded to accommodate a correspondingly threaded top 36, which seats the upper end of a coiled spring 31 holding it in place around the pin 35a. The lower end of the spring seats on the top of the plunger I1, and the spring holds the lower conical end of the pin against the top of the plunger.

In operation the thumb trigger 35 is manually depressed; thus releasing the grip of the plate 29 on the rod 24, whereupon the spring 26 pushing on the collar 27, raises the rod 24. The rod 2 raises the outer end of the rocker arm 29, which in turn raises the plunger l1 and leaves the central opening of the body I unobstructed. A can, from which it is desired to dispense liquid, is placed inside the body. I with its lower end resting on the resilient seat 5. The trigger 35 is depressed and the rocker arm 29 is manually pushed downward lowering the'plunger onto the top of the can and tightly seating the bottom of the canon the resilient seat 5. By release of thumb pressure the plate 29 is then allowed to assume its normal position and holds the rod 24 from vertical movement, thus holding the lower annular end of the plunger tight against the can top, and the lower end on the seat '5.

of the can tightly seated pressure on its top 36, and its lower conical end punctures the top of the can 2 as shown at'38.

The upper end of. the spout is partially rotated from its normal vertical position about the axis of its lower end, which movement causes the cutting blade I I to cut a hole I4 in the bottom of the can, thus allowing the liquid to pass from the can into the base reservoir 4, and thence into the spout. The end of the spout is then rotateduntil its 1ower end is below the base reservoir 4 and the liquid pours out through the spout. A slight amount of liquid remains inrthe reservoir 4. Each time the contents of a can are dispensed the same amount of liquid remains in the reservoir, thus assuring delivery of the full contents of each-can through the spout.

Obviously, the invention is susceptible of embodiment in forms other than that which is illustrated in the accompanying drawings and described herein, and applicable for uses and purposes other than as detailed, and I therefore consider as my own all such modifications and adaptations and other uses of the form of the device herein described as fairly fall within the scope of my invention.
