- SPOU'T.

Application filed June 4,

This invention relates to spouts for syrup pumps and the like and its object is to prevent the spout from dripping after pouring therefrom.

And a further object of the invention is to construct the spout in a novel manner which will prevent dripping without reducing the fiow of the fluid from the spout.

In the accompanying'drawings I have illustrated the invention in a syrup pump, as

a selected embodiment, 'andreferring thereto,

Fig. 1 is a side elevation of so much of such a syrup pump as is necessary to understand the invention.

Fig. 2 is a front elevation of the pump as shown in Fig. 1.

Fig. 3'is a sectional view on the line 33 of Fig. 2.

Fig. 4 is a top plan view showing the spout in section.

Referring to the drawings, 5 is the head, 6'

is a rod for supporting a syrup charge chamber, 7 is the spring pressed plunger rod, 8 is 5 the plunger rod handle, 9 is the discharge tube and 10 is the spout of a syrup pump. Heretofore it has been customary to provide the spout with a passa e 11 of substantially the same cross sectiona area throughout its 3 length. It is a common experience with these and other pumps that the liquid will drip from the discharge end of the spout after a pouring operation is completed. I have found that dripping may be .pre-

vented, without reducingthe flow of the fluid from the spout, by dividing the passage at the discharge end of the spout into a plurality of separate and independent passages, properly dimensioned. For example, if the cross sectional area of the passage in a discharge spout is 9/16 of an inch it will drip beause the surface tension of a drop of fluid at the end of the spout will not be suificient to retain the drop on the spout; but if the passage is divided at its discharge end into two discharge passages each having a cross sectional area of 9/32 of. an inch, there will be no dripping but, on the contrary, there will be a drop formed at the outer end of each discharge passage and the surface tension of each drop .will hold it on the spout. Therefore I divide the passage 11 at the discharge end portion of the spout into two

passages

12, 13 by a partition 1.4, the total cross sectional area of the drop there will surface tension of each drop will be sufiicien't to hold it on the spout. The two drops at the ends of the

passages

12, 13 will be spaced apart so that, under ordinary conditions, they will not join to make a large drop. In the practical use of a syrup pump a drop may or may not form at the discharge end of the spout, and the same is true of a spout made in accordance with my invention; but if the operation of the pump is such as to produce a be two drops formed on a spout constructed'in accordance with my invention. The cross sectional area of the discharge end of each passage is such that the surface tension of the drop will be sufficient to hold the drop on the spout. I prefer to bend the

passages

12, 13 downward at their outer ends, as indicated at 12, 13 in accordance with the usual practice in syrup pumps, but my invention may be embodied in spouts for other uses than syrup pumps and the passages may be otherwise shaped to suit different conditions. I have found it to be sufficient, in practice, to divide the passage of a syrup pump spout by a single partition into two discharge passages, but more than two discharge passages may be provided when required. I have shown and described the invention in a simple form which I have found entirely satisfactory in syrup pumps, but I reserve theright to make all such changes in the form, construction and arrangement of parts as may be necessary for different adaptations of the invention and within the scope of the following claims.

I claim:

1. A spout for syrup pumps and other adaptations having a fluid passage therein divided into a plurality of elongated dis charge passages spaced apart at the discharge end portion of the spout, the area of each discharge passage at its discharge end being such that a drop formed at said discharge end will be held by its surface tension on the spout.

2. A spout for syrup pumps and other adaptations having a fluid passage therein divided into a plurality of discharge passages spaced apart at the discharge end of the spout, the area of each discharge passage v 1 1,70e,458 UNITED" STATES: PATENT ori-"icE.

at its discharge end being such that a drop formed at said discharge end will be held by its surface tension on the spout, the aggregate capacity of said discharge passages being equiyalentto the. capacity of the fluid passage.

A spout for syrup pumps and other adaptations having a fluid passage therein, a

partition in the spout dividing the fluid passage at the discharge end ofthespcut into a plurality of discharge passages, the outer ends of said discharge passages extending angularly tothe general; direction at said passages andbeingspaeed apart from each other.
