-1 Claim.

and has particular reference to spring actuated valves therefor.

One object of the invention is to provide an improved device of the character described hav-' ing few and simple parts, and which is particularly easy and ,quick to assemble and to clean,

and which is neat and attractive in appearance,

and durable, reliable and efficient in use,

Another object of the invention is the provision of a device of the nature set forth having a onepiece valve, finger piece and spring, these parts being cooperative with each other for a simplified mounting without requiring screws, rivets, pins or the like, whereby the structure need merely be snapped into fully operative position.

Another object of the invention is the provision of a device of the type mentioned wherein the operating structure is resilient to afford a l more uniform and greater range ofspring action part, which may be the valve or the immediate actuator therefor, forms a strip spring which causes closing of the valve in cooperation with other I Another object of Itheinvention is to furnish a device as stated, wherein a slide valve element is connected at an acute angle to an actuator, or pivot member, th'ese beingso related to each other that upon retraction of the valve element the angle is decreased or the distance between'the plane of the valve element and the pivot point is dimin-r' ished, whereby a spring portion can be provided in the valve element or at the connection in the pivot member, so'that downward pressure on the connection functioning as a finger piece causes opening of the valve, and release of the pressure causes the spring to increase the angle or distance referred to in order to project the valve along its plane to closing position.

Other objects and advantages of the invention will become apparent as the specification proceeds.

With the aforesaid objects in-view, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the (Cl. 222-473) This invention relates to dispensingdevices,v

subjoined claim, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

In the drawing:

Figure 1 is a view in side elevation showing a device embodying'the invention with the valve closed.

Fig. 2 is a. top plan view thereof.

Fig. 3 is a view in side elevation of a cap embodying the invention, like that of Fig. 1, but with the valve retracted to open position,

Fig. 4 is a top plan view of cap but with the valve-spring unit removed.

Fig, 5 is a central sectional view of Fig. 2

Fig. 6 is a bottom plan'view of the valve-spring unit.

Fig. 7 is a diagrammatic sectional view of a modification.

The advantages of the invention as here outlined'are best realized when'all of its features and instrumentalities are combined in one'and the same structure, but, useful devices may be produced embodying less than the whole. 4

It will be obvious to those skilled in the-art to which this invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing. therefore, is submitted merely as showing the preferred exemplification of the invention. Referring in detail to the drawing, Ill denotes a .device embodying the invention. The same may include any container, such as a glass bottle ll, having a new control means l2 suitably connected thereto. For example, the means 12 may comprise a cap l3 internally threaded at H! for detachable connection to the container ll. Formed in or on the cap I3 is a valve seat l5 which is desirably elongated, and with which communicates an outlet or part l6. If the latter be arranged as a spout, the port is preferably at one end of the valve seat I5. Adjacent to the other end of the valve seat, and lying in the central vertical plane of the latter is a handle ll connected to the cap, and desirably extending downwardly. For reasons hereinafter apparent,

' the horizontal plane of the valve seat I5 is spaced a substantial distance above the handle ll. More specifically, the decorative dome wall l8 carries a thickened wall portion l8 that forms a portion of the seat l5, and an upward opening recess or chamber 20 being formed lateral to the dome and above the handle. While the handle may ice-variously constructed, it is hollowed out may be made by a reverse curve.

at 2| for lightness, and reenforced by a central web 22. v

The valve-spring unit 28 is preferably made of a single piece of resilient material such as sheet stock consisting of steel, plastic,'or other materials. It may be of generally U-shaped form,

. having arms 24, 25, disposed at an angle to each other. The arm 24 may include a slide valve portion 26, and is primarily lineally movable. This arm is therefore substantially longer than the arm 25 which operates mainly angularly as by a pivotal action or the like. As the arm 25 controls retraction of the valve by said angular movement, it may be-called an actuator. The bight portion 21 of the unit -23 serves as a finger piece to cause the angular movement of the arm 25. It will be noted that the arm 24 may comprise a section of substantial length between the valve part 28 and the finger piece 21. For example, this section may include a part 28 plane with the valve and a part 29 which is curved for added flexibility and as a portion of the finger piece 21. The free end of the arm 25 may have a hook portion 30 that If need be, a stop 3| may be formed by striking out a tongue from the part 28, and a notch 32 may be cut in the end of the hook 38. This completes thevalve-spring unit 23.

Means is provided for slidingly guiding the arm 24 along the valve seat I5, including a pair of lips or flanges 33, which may have enlarged undercut portions 34 that confront each other. The lips 33 retain the valve in a true lineal sliding path while the undercut parts 34 prevent separation of the valve from the seat l5. For coop eration with the stop 3|, astop portion 35 may be cast on the top of the dome wall l8, to function as in Fig. 5, the recess 20 affording ample clearance space for the stop when the valve. is retracted.

being two openings 31 for receiving the tines. of

the notched book 30. These tines extend in part into the openings 2|, so that a lost motion pivotal action is obtained, because the hook 3||-slides in and out relative to its receiving openings 31 in course of the angular movement of the arm 25.

curved hook is adapted to slide on an edge of the socket to accommodate the swinging action of the arm 25, with the hook moving in an outward direction upon downward swinging movement of the short arm. The entire unit 23 is removable for thorough cleaning of the device, by upwardly springing the short arm 25 to remove the portion 38 from its socket.

For assembling, the arm 24 is first inserted and engaged in the undercut lips 34, and then the arm 25 is bent upward and the hook 38 is snapped into the openings 31, which constitutes an extremely simple operation.

For opening the valve 26, the operator holds the handle l1 and presses down on the finger piece 21, causing the valve-spring unit 23 to assume the position of Fig. 3. When this occurs the hook turns and slides on an edge of the openings 31, some deflection occurs in the arm 25, the bight 21 tends to close and may move into contact with the handle as a stop, deflection.

occurs in curved spring part 29, and deflection also occurs in the straight part 28. The deflection of the part 28 is clearly shown in Fig. 3 and is beyond the supporting track 36, but there is ample clearance for the stop 3|. It is therefore noteworthy that the valve arm 24 serves as a spring, particularly the section comprising the part 28, 29 thereof. But the valve,,26 and the For instance, the maximum inward movement is shown in Fig. 1, in which the closed end of-the notch .32 rests on the top of the rib, a result which is possible because the openings 31 are interconnected by a. slot 38, which may be optionally provided.

It will now be clear that in the position of Fig. 1, the valve-spring unit 23 is automatically retained in operative valve closing position. Thus the valve cannot be withdrawn accidentally because the hook 38 prevents such movement.

Likewise the arm 25 could not drop out of place, because the undercut lips prevent such movement of the unit. Thus the latter is secured horizontally at one end and vertically at its other end, with spring pressure effective between the ends to maintain the required positioning. Further, the curved hook 38 provides for pivotal lost motion of the short arm 25, and since the socket is an opening 31 in a thin plate-like portion, the

immediately adjacent part remains quite plane.

- It is desirable to note that whe'n the valve is re tracted, the angle between the arms 24, 25 diminishes and also the distance between the pivot point of the arm 25 and the arm 24 as evidenced by the downward flexure of the parts 28, 29. In a sense, therefore, the unit as a whole may be considered as bent, with the arm 25 serving as a motion controlling link or guide. Because of the substantial length of the sections 28, 29 and the provision of the bight 21, here is ample, large range resilience, without un ue variation in stress, so that deflection of the arm 25 need not occur, as would be the case if the part 20 were fixed instead of forming a lost motion pivot. But if the arm 25 were so fixed, the tension would increase much more sharply. Another important advantage is an ample leverage, which is well placed for easy and convenient action at the finger piece 21;

It is noteworthy-that the valve spring unit is well balancedand stable, even the arm 25 being guided by the side walls of the recess 20 and having a reliable footing at the openings 31.

Upon release of the finger piece, the unit returns to initial position instantly, until limited bythe stop engagement at 3|, 35. The unit is again completely balanced and stable. This would not be the case if a hinge were provided instead of the folded portion 21, but would obtain if a spring hinge were used, although the latter would complicate the device and would require a casing to function as a finger piece in place of the bight at 21.

a slot 44 in the valve part, and projecting to form a stop such as 3|. Undercut retaining lips 34 may be provided for the valve and correspond-' ing lips 45 for the spring, the latter being in other respects like the spring shown in the device l0, except that it is provided with a toe 46 inserted in a slotted member 41 that is stationary, whereby the short arm of the spring is flexed to a desired degree when the valve is retracted as in Fig. 3. Thus there is a greater degree of spring pressure for advancing the valve, and this is sufficient to overcome any friction with the guide 45 in the angular deformed position of the spring. Incidentally this illustrates an advantage of the device In in which the guide 34 is remote and hence causes little friction because the leverage is great. In the device 40, the only bottom support for the long arm of the spring may be the valve itself, hence this arm is subjected to less flexure than the arm 24 of the device II), but this is compensated in part by flexure of the shorter arm; There may be any desired clearance in the opening 44 to assure smooth workin of the device.
