DISPENSER Filed. Jan. 1e, 1928 Patented June 18, 1929.



Application led January 16, 1928. Serial No. 247,132.

The object oi. my invention is to provide a dispenser particularly intended and adapted for use with-shaving cream Vand products 0l a somewhat similar consistency, but capable of use for a great variety of products ol very simple and inexpensive and eilicient construction.

A further purposey of the presentrinvention is to provide such a, dispenser in which 1o special means is provided for imposing pressure on the contents.

Still another purpose is to provide in such a device a desirable control means having parts so arranged and constructed as to permit thecrcam to be discharged from the dispenser in small quantities and yet to prevent leakage and to'ati'ord such cut-off means that no drop or surplus of cream will be left on the outside of the dispenser.

invention consists in the construction, arrangement and combination of the various parts of my dispenser, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective View of a dispenser embodying my invention.

Figure 2 is a vertical,. detail, sectional view taken on the line 2-#2 of Figure 1.

Figure 3 is a similar View of the lower part of the dispenser, the compression spring being shown in another position. l

Figure 4 is a horizontal, sectional view taken on the line 4-4 of Figure 2.'

Figure 5 is a vertical, sectional view through the dischargey nozzle of the dispenser; and

Figure 6 is a detail, sectional view taken on the line 6-6 of Figure 5, the movable cap forming part of the discharge nozzle being shown. at its inner limit of movement.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally the casing forming a part of my improved dispenser. The casing 10 is a tubular member, which prior to the assembly otdthe other parts thereon is open at both en s.

Mounted in the casing 10 and extending diametrically across the easing and supported in its wall at its opposite sides isa. shaft 12. On the shaft 12 are rotatably mounted two sleeves 14, each provided at its outer end with an annular rib 16.

With these and other objects in view, my`

Slidably received in the casing 10 above las shown in Figure 2, so that by rotating the spring it may be screwed upwardly or downwai-diy on the shaft 12.

The casing 10 has at its lower end in its outer surface an annular groove 32.

Iprovide a bottom cap 34 having an annular flange 3G provided with an annular, internal groove 38. The cap 34 is provided on its upper surface with a pair of spaced ribs 40,*which receiver-:between them the end 42 of theN spring 30. The cap is placed below thev casing l() with'the spring end 42 received between the guides 40. f

f The resilient expansion ring 33 is then compressed in the groove 32 until the edge of the flange l361is'k slipped over the lower part of the jfexpansionvringand then the cap is slipped intoplace as shownr in Figures 2 andv 3, whereupon the ring 33 expands until it stands partly in the groove 38 whereupon the cap will be rotatably but non-removably mounted on the casing.

By rotating the cap, the spring will be rotated .and caused to travel up and down on the`-sha'ft"12.

The sleeves 14 reduce the friction between Aing 46 is a tube 48 havingat its inner end a valve seat 50.

Preferably on the upper part of the tube 48 is a longitudinally arranged rib 52 Mounted on the outer end of the tube 48 is a sliding cap 54.

In the under side of the tube 48'is a dis- I charge opening 56 elongated circumferentially of the tube 48.

The cap 54 has in its upper part a slot 58 to receive the rib 5 2.` In its lower part the cap 54 has a discharge opening 60 likewisev circumferentially elongated. The material of the cap 54 on both sides of the opening 60 is tapered as indicated at 62 (Figure 2).

I provide a combination valve and ,plunger structure, comprising a cone-shapedvvalve 64, adapted to c coact with the seat 50. Connected with the valve 64 is a stem 66 projecting into the tube 48 and having in its outer end a plunger member 68'. VVThe plunger member fits snuglyf'in the tube 48 and prol nected with the outer end of the cap 54 by means of a pin 74.

The inner end of the stem 66 has a portion 76 tapered toward the valve 64, and the outer end thereof has a portion 78 tapered toward the plunger 68.

In the actualvuse of my dispenser, the cap 44 is removed, the lower cap 34 is rotated until the larger portion of the spring 30 is below the shaft l2 as illust-rated for instance in Figure 3, a charge of shaving cream or the like 80 is placed in the containerk 10, and the cap 44 is then replaced.

The spring 72, being compressed between the end of the tube 48 and the closedV end of the cap 54, pushes the cap outwardly for setting the valve 64, and holding the opening 60 in the cap 54 outwardly just beyond the opening 56 in the tube 48. The cap 34 is then rrotated for causing the spring 3() to travel upwardly on the shaft 12, so that a substantial portion of the spring will be compressed between the shaft 12 and the plunger 18 for imparting substantial pressure on the shaving cream 80.

When it is desired to take a small ycharge of cream from the dispenser, .the cap 54 is pressed toward the container, thus compressing the spring 72 and shoving the plunger 68, the stem 66 and the valve 64 inwardly.

The cream being under pressure will travel into the space in the tube 48 around the stem 66. r

The inward movement of the cap 54 brings the opening 60 to register with the opening 56 (see Figure 5).

Someof the cream will pass out through the openings 56 and 60 and when the pressure on the cap 54 is released, the spring 72 will move the cap outwardly, causing the opening 60 to move to position out of registry with the opening 56 and immediately thereafter causing the valve 64 to be seated.

The sharp edge around the opening 60 will not leak, and which willnot leave a drop of cream hanging around the discharge opening.

.Y -My present nozzle accomplishes these desirable purposes. n

By the use of the ring of leather or similar material, I impart enough friction to the parts, so that the action of the spring on the cap 54 and connecting parts is in itself quick, and I also prevent any leakage of cream past the ring 70.

One trouble, which I have found great diticulty in overcoming, has been due to the fact that the cream in the tube 48 is under pressure after the valve 64 is closed, unless someA means for relieving such pressure is provided, and when such pressure exists, it l is difficult to make a nozzle from which the cream does not ooze out.`

I have relieved the pressure on the cream in the tube 48 -after the valve 64 is, closed by providing the tapered portions 76and 78 at thek ends of the stem 66.

I have tried a nozzle of the kind here shown without the tapered portion ,and`

found it impossible to avoid some oozing of the cream.

If a little cream squeezes out, the device is unsatisfactory. kSince the device is used in barber shops, this is anfundesirable feature, displeases customers,l and is of considerable importance. I found that by forming'the stem 66 with the tapered portions 7.6

and 78 the oozing outof the cream is avoided..

f This result is accomplished, as I believe,

because when the cream is traveling outc wardly, when thenozzle is in discharging position, as shown in Figure 5, the movement of the cream causes fvacuumpockets 82 and 84 around the tapered portions 76 and 78. A

In this connection, I form the openin 56 of such size as to easily take care o -all cream that will discharge through the passage around the stem .66'without imposing any back pressure.

IVith the structure valve 54 is closed, the cream underpressure in the passage around the stem 66 Willen:-V

pandl into the air pockets, and the pressure on the cream will disappear, and hence there is not the tendency for the cream to force or ooze its way out through the opening 56, and between the tube 48 and the walls of the cap 54 to the opening 60. as occurs when no tapered portions 7 6 and 7 8 are provided.

The feature just described is one of great importance in a device of this kind because it results in a discharge nozzle from which the cream will not ooze out.

here shown, when the l lll My entire device is of simple construction and is intended to be furnished primarily to barbers, so that the barber can use fresh shaving cream for each customer under the most sanitary conditions.

I claim as my invention:
