' NOZZLE.

Specification of Letters Patent.

- This invention relates to nozzles of the character employed in connection with receptacles holding liquid to be dispensed, such liquids, for example, as molasses and An object of the invention is to avoid waste of the liquid by leaking thereof from the nozzle. Such leaking is sometimes due to looseness between the valve plate and the orifice plate, and at other times to the valve handle being inadvertently moved sufiiciently to open the nozzle orifice, the latter often being the result of a person accidentally knocking against the handle.

A further object of the invention is to avoid looseness between the valve plate and the orifice plate.

Another object is to make provision for latching the valve .plate in closed position, so that it cannot be accidentally opened.

Other objects are simplicity and inexpensiveness of manufacture.

The accompanying drawings illustrate the invention:

Figure 1 is a side elevation of a nozzle embodying the invention.

Fig. 2 is an enlarged fragmental' plan of the nozzle shown in Fig. 1.

Fig. 3 is an enlarged front elevation from the right of Fig. 1.

Fig. 4 is a side elevation partly in vertical section on line indicated by X -X*, Fig. 3.

There is provided a hollow body 1, the

bore thereof being indicated at 2. At one end the body 1 is provided with a screw threaded portion 3 for connection with the container with which it is to be used. The other end of the body 1 forms a curved plate 4 through which the bore 2 extends to form the orifice 5 of the nozzle.

Slidably fitting the orifice plate 4 is a valve plate 6, the rear face of said plate being concave to correspond with the convex curvature of the front face of the plate 4. The plate 6 is provided with a stud 7 which is inserted in a coil spring 8 having one end resting against the plate 6 and having its other end inserted in a spring chamber 9 formed in a valve-operating handle 10.

The handle 10 is provided with arms 11 pivoted at 12 to the opposite sides of the body, the axes of the pivots 12 coinciding with the center of an imaginary circle of which the outer face of the plate 4 constitutes a portion.

The construction above described is old and the invention resides in the additional features to be described hereinafter.

The end of the'spring 8 lying within the recess 9 seats against a plate 13 which in turn rests against the inner end of an adjusting screw 14 that projects through an orifice 15 in the handle 10 and that engages a nut 16 positioned in the recess 9. Turning of the screw 14 changes the position of the plate 13 relative to the valve plate 6 so as to produce more or less compression of the spring 8. Thus, when the spring 8 looses some of its expanding power, the screw 14 will be adjusted to compress the spring further so as to maintain a fluid-tight joint between the valve plate 6 and the orifice plate 4. By drilling the orifice 15 into the handles of nozzles already manufactured and inserting the nut 16 and plate 13 in the recess 9, this particular springadjusting feature of the invention may be readily applied to existing nozzles.

Projecting laterally from the handle 10 is an angular bracket 17 which, as shown, may be attached by a screw 18 projecting through one leg to the handle 10 of any existing nozzle of the type shown. The other leg of the bracket 17 projects laterally from the handle and is provided with a series of holes 19, in any one of which may be positioned the pivot 20 of a latch 21. The pivot 20, in this instance, is in the form of a screw which is held in place by a nut 22. When the valve plate 6 is in position to close the orifice 5, a spring 23 on the screw 20 yieldingly holds the latch 21 in position to engage a notch 24 which is cut in one edge of the plate 4.

The latch 21, when engaging the notch 24, prevents the valve plate 6 from being moved into open position; and, when it is desired to discharge liquid from the container to which the nozzle is connected, the operator will grasp the handle 10 and press with his thumb against the thumb piece 25 of the latch 21 so as to swing the latch out of the notch 24, and he will then raise the handle 10. In closing the nozzle,the latch 21 will slide upon the adjacent edge of the plate 4 until the latch registers with the notch 24 and the latch will thereupon automatically move into said notch. It'is obvious that the notch 24 may be readily provided in nozzles already manufactured by filing the edge of g the plate 4:. The series of holes 19 provides for selective positioning of the screw 20 to fit the latch to various widths of nozzle.

I claim: I

1. In a nozzle, a hollow body having a curved plate at one end provided with an orifice, a curved valve plate slidably fitting the orifice plate, a handle having a spring chamber, a plate in the spring chamber, a spring inserted in the spring chamber between the last named plate and the valve plate, a nut mounted in thehandle, a screw engaging the nut and having its inner end seated against theplate in the spring chamher, and arms provided on the handle and pivoted to the body.

V ,2. Ina nozzle, a hollow body having a curved plate at one end provided with an orifice, a curved valve plate slidably fitting the orifice plate, a handle, a spring between the handle and the valve plate, arms provided on the handle and pivoted to the body,

3. In a nozzle, a hollow body having a curved plate at one end provided with an orifice and having a notch in one edge of the plate, a curved valve plate slidably fitting the-orifice plate, a handle, a spring between the handle and the valve plate, arms provided on the handle and pivoted to the body, abracket fastened to the handle and projecting laterally therefrom and provided with a hole, a pivot extending through the hole, a latch on the pivot adapted to engage the notch when the valve plate is closed over the orifice, and a spring tending to hold the latch in engagement with the notch.
