DISPENSER CHARGE REGUATING lDEVIGE Filed April 50. 1929 Patented Dec. 2, A193() UNITED STATES i W. FITCH,` OF DES MOINES, IOWA DISPENSER CHARG-E-REGULATING DEVICE Application filed April 30j The obj ect of my invention is to provide a dispenser charge regulating device of simple, durable and comparatively inexpensive construction. y
More particularly, it is my object to provide a regulating means for the dispensing nozzle of a dispenser of the type shown and described in my co-pending application Serial No. 337,345, filed February 4, 1929.
A further object is to provide such a regulating means consisting of a fitting having a plurality of stop shoulders of different heights to coact with another tting which may be adjusted relative to the rst fitting to engage the desired stop shoulder.
Still a further object is to provide the first litting in theform of an angular member having a stop shoulder on each side thereof andthe second fitting in the form of a tubularvmember adapted to slide vertically over the first fitting and having an inwardly eX- tending flange to engage one of the stop shoulders, the flange serving to prevent rotation of the second fitting relative to the first fitting.
Still a further object is to provide an anto receive the flange of the second fitting, whereby the second fitting may be rotated relative tothe first fitting for positioning the flange to engage another of the stop shoulders. v
lVith these'and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, ashereinat'ter more iully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which: v

Figure 5 is a similar sectional view on the line 5-5 of Figure 2, showing the parts in a different position.
Figure 6 is a sectional view on the line 6 6 of Figure 4.
Figure 7 is a sectional view on the line 7 7 of' Figure 5; and
Figure 8 is a sectional view of the end olf the Y nozzle shown in Figure 2, showingit in a different position. Y On the accompanying dra-wings, I have usedthe reference numeral `10 to indicate a cylindrical casing. .The casing 10 is provided with a bottom member 12 having a depressed boss 14 at its center; In the boss v14, a socket 16 is formed.
Adjacent the top of' the casing 1() I provide a plurality of inwardly extendinglugs 18. A top for the casinglO is indicated at 20 andis provided with a plurality of outwardlyextending lugs 22. The lugs 18 Vand 22 may coactV upon rotation of the cover 20, whereby the cover is secured to the casing 10 some-v 'y what similar to a bayonet joint connection. nular groove around the first fitting adapted Secured to the cover 2O is a fitting A, over which a fitting B telescopically fits. The fitting B is constrained to move upwardly, due to a spring 24 interposed between an upwardly opening socket 26 in the fitting A and in a downwardly openingv socket 28 in the fitting B. Y
Vithin the casing 10 I provide a plunger tube 30, havinga shoulder 32 adapted to engage a shoulder 34 formed in the fitting A. Above the shoulder 32 the plunger tube 30 is reduced and its upper end is secured to the fitting B as by a screw-threaded connection.
Within the casing 10 and surrounding the plunger tube 30, I provide a follower disk 36. An enlargement 38 on the lower end of the plunger tube 30 prevents removal of the disk 36 from the tube when the cover 20 and the parts carried thereby are removed from the casing 10. The enlargement 38 is adapted to coact with the socket 16 in certain positions of the plunger tube 30.
The foregoingrconstruction is similar to that shown in my co-pending application,
with the exception of the shapes of the fittings A and B, which will now be described and which constitute the patentable subject matter of this application. The operation of the dispenser is fully disclosed in my co-pending application, but l will briefly refer to it later in this specification.
The fitting A is provided with a plurality of fiat sides 40, the fitting being angularshaped and having as many sides as adjustments are desired. Adjacent the lower end of each side 40 l provide stop shoulders 42, 44 and 46 with the exception of one side 40, on which l provide no shoulder, for which side, the cover 2O acts as a stop shoulder. The stop shoulder 42 is of predetermined height and the stop s ioulders 44 and 46 are progressively higher, as indicated bythe reference characters l), c and CZ, vthe reference character a indicating the lid`20 as a stop shoulder.
The fitting B has a circular interior adapted to just fit over the corners of the fitting A. The fitting B could therefore rotate on the fitting A except that I provide an'inwardly extending flange 48 to normally prevent such rotation. The flange 48 may engage the cover 20 or any of the stops 42, 44 or 46, depending on which stop shoulder it is positioned above, or in other words, which side 40 of the fitting A it engages.
It will therefore be obvious that the fitting B will be positioned on the fitting A in any predetermined position when the parts are assembled. However, after they are assembled it is desirable to change the adjustment, which can only be accomplished by rotation of the fitting B relative to the fitting A. The fitting B, however, cannot be removed from the fitting A, due to the shoulders 32 and 34 engaging each other. I therefore provide an annular groove 50 at a predetermined point around the fitting A so that whenever the flange 48 is in registry with the groove 50, the fitting B may be rotated.
The sprin 24 normally positions the flange 48 slightly above the annular groove 50, as clearly shown in Figure 2. When the 'fitting B is pressed downwardly a slight distance so that the lower edge of the fitting B is in alignment with the lower side of the groove 50, as shown in dotted lines in Figure 6, the flange 48 will be in registry with the groove 50 and the fitting B may now be rotated to any desired position.
Figure 5 illustrates the fitting B being rotated in the direction of the. arrow 52 from the position shown in Figure 4. the flange 48 of course, being in registry with the groove 50.
From the foregoing construction, it will be obvious that the fitting B will move downwardly a predetermined distance, depending on which stop shoulder the flange 48 will engage. T he. fitting B will be normally moved straight down by the barber or whoever is di f.;- pensing the material from the casing 10 so that the fiange 48 will prevent rotation of the fitting relative to the fitting and will merely pass the groove 50, thereby maintaining the adjustment at which the fitting B is made.
Practical operation I will now describe the operation of the device, wherein it will become obvious why variations are desirable and how variations are accomplished by the coaction of the flange 48 with the stop shoulders 20, 42, 44 and 46. T he fitting B is manually engaged and forced downwardly, whereupon the enlargement 38 on the plunger tube 30 will enter the socket 16. Further downward movement of the fitting B, as for instance to the position indicated at b when the flange 48 will engage the stop shoulders 42, as shown in Figure 2, will cause the material in the casing l() to be forced upwardly through the plunger tube 30.
On. the nozzle 54 of the fitting B l provide a rubber cap 56 having a slit opening 58. lhe pressure of the material through the nozzle 54 will cause the ends of the cap 56 to be forced outwardly, as shown in Figure 8, thereby allowing the material from the nozzle 54 lto be discharged in the form of a ribbon indicated at 60.
As the fitting B is released and forced up wardly by the spring 24, there will be a ten dency for the material within the tube 80'to remain stationary, thereby pulling inwardly on the cap 56, which closes the opening 58 to the position shown in Figure 2.
lVlien the flange 48 is adjusted to engage the cover 20 the enlargement 38 on the lower end of the plunger tube 30 will be moved downwardly to the line a. Coaction of the flange 48 with the shoulders 44 and 46 will cause the enlargement 38 to be stopped at the positions c and respectively. Thus, different quantities of the commodity from the dispenser are ejected from the nozzle 54, depending on the position of adjustment of the fitting B.
Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably in eluded within their scope.
l claim as my invention:
