EXTRACTORYDEVICE FOR SHAVING CREAM AND THE LIKE Filed June 22, 1934 Patented July 16, 1935 UNITED STATES EXTRACTOR DEVICE SHAVING CREAM AND THE LIKE Joseph R. Vezina, Springfield, Mass.
' Application June 22, 1934, Serial No. 731,925
6 Claims.
This invention relates to improvements in extractor devices for shaving cream and the, like.
An object of the invention is to provide a structure for withdrawing and delivery a measured quantity of shaving cream from a suitable recep-' tacle and delivering it onto a shaving brush.
One of the features of my improvement is to forciblyeject. the liquid, or creamlike substance, in a spray efiect onto the brush, when it is operated. A It comprises, broadly, a reciprocable member that is adapted for attachment to a bottle, or other receptacle, in which the substance to be ejected is placed, whereby, when the reciprooable member is moved downward, the substance is automatically delivered. When-the reciprocable member is moved or drawn upward, a measured quantity is drawn into a barrel member of the device, and, when moved downward again, as stated, the dreamlike substance is delivered onto the brush.
' Located within the device are two valves which operate in opposite directions, one of which permits the substance to-be ejected, when a downward movement is imparted to the device, and the other, or inlet valve, is then closed, and when an upward movement is imparted to the device, the discharge valve is closed and the' other is opened, as will be fully described.
Referring to the drawing:-
Fig. l is a vertical, sectional View of a receptacle in which'the semi-liquid is placed, with the device also shown in section and located therein.
Fig. 2 is a transverse, sectional view on theline 22 of Fig. 1, looking in the direction of the arrows.
Fig. 3 is a transverse, sectional view on the line' 33 of Fig. 1, looking in the direction of the arrows.
Fig. 4 illustrates a stopper construction for installing the device in a bottle having a narrow neck opening.
' Fig. 5 illustrates the device. installed on any suitable receptacle, and 45 Fig. 6 shows it located in a tumbler.
Referring to the drawing in detai1:-
I indicates a glass container, in which the creamlike substance 2 is placed. 3 designates a closure cap having a threaded connection with 50 the container. Thds cap is formed with an opening 4, in which is slidablylocated the delivery, tubular member 5. Secured to the upper end of this member is a cap having an opening i, in
P which is located the shut-oii needle valve 8 and the tubular delivery. tube 9, having the discharge opening IE3. A packing, or gasket, ring, is indicated at l l and a ring I2 is located on the upper end of the tubular member I3, which is located on the tubular member 5. I4 indicates a ring secured to the tubular member 5 with the set '5screw 15.
Located below and engaging the ring I4 is an expansive spring it; the lower end of the spring rests on the shoulder ll of the threaded member i 8, in which the lower end of the tubular member 5 is slidably secured. Located on and secured to the lower end of the tubular member 5 is the tubular-pistcn member is, having theflange 20 against which the packing ring 2| is placed, that is retained in place by thering 22 by meansxof the turnedover edge, orflange 23, of the tubular member I3. 26 indicates a ball valve resting on the upper end of the tubular member I9. 25 indicates a split ring secured on the inside of the member 5 for limiting the upward movement, or d travel, of theball valve 24, when the device is operated. 26 designates a tubular cream-receivingreceptacle member that has a threaded con nection with the threaded member [8. Its lower end is formed with theinlet openings 28 for the 25 creamlike substance 2 and thevalve seat portion 27 for theball valve 29. I i
- Asshown, the device normally rests on the bottom 35 of the receptacle .l.
In Fig. 4, is illustrated a cork 3i, in which th slidable tubular member 5 is located. The extractor device .is not, therefore, limited for use with the threaded cap 3, shown in Fig. 1.
Fig. 5 shows the device attached to acan receptacle 32, by merely-securing the same in an opening of thecover 33. i
Fig. 6 illustrates the use of the extractor device in an ordinary tumbler, oropen receptacle 34.
The operation of the device may be described as follows:--Considerthe parts in the position shown in Fig. 1. When the user presses downward on the cap 6 against the tension of the spring IS, the cream in thebarrel member 26 is forced upward through the tubular piston l9, past theball valve 24, through the slidable delivery tubular member 5 and out through the delivery tube 9, as shown at it. The ball valve 29is now in its closed position on its valve seat 21. When the user removes his hand from the cap 6, the force of the expansive spring it returns the tubular member 5 to its original position. This movement ca see thesmall ball valve 24 to close and thelarge ball valve 29 to open, whereby a fresh charge of cream is drawn into thebarrel supply member 26, ready for delivery, when the user presses downward again on the cap 6.
The needle valve 8 is closed, when the device is not in use, to prevent the cream which may be retained in the tube 5 from leaking out through the tube 9 and orifice Hi.
It is, of course, obvious that the operation of the device is the same, when used with the can structure, shown in Fig. 5, or the tumbler, shown in Fig. 6.
It will be observed that thesplit ring 25 not only limits the upward movement of the ball valve 2 but also p rmits the creamlike, or liquid substance, to flow freely through the split ring, as its ends are separated, or spaced apart, as shown in Fig. 2. iChe valve 2 therefore, cannot completely shut off the flow, when it is moved against this split ring. I
It is to be understood that the use of the split ring 251s not a necessary structure, as any stop element for theball valve 24, as a pin, may be used which wili'permit the creamlike substance to flow freely up the tubular member 5 and past thevalve 24.
It should be stated that when the reciprocable tubular discharge member 5 is moved upwardly by the expansive force of the spring It, a partial vacuum will be produced in the tubular member 5 and also in the delivery tube 9, or spout, whereby any possibility of the creamlike substance dripping from the discharge opening I0, is elfectually prevented. The device, therefore, can be placed on any piece of furniture, without injuring the same;
What I claim is:-
1. In combination, in a device for the purpose described, for intermittently discharging a ,measured quantity of a creamlike substance, said device comprising a reciprocable tubular member slidably located in the cap member of a suitable receptacle in which the substance to: be delivered is contained, a separate measuring quantity barrel member for receiving the substance and slidably connected to'the reciprocable tubular member and formed with an inlet opening at its lower end, a hollow piston slidably connected to: said measuring quantity barrel member, a valve for normally closing said opening in the said barrel member, a second valve located in the said tubular member and at the upper end of the hollow piston, said valve being also: normally closed, means in the reciprocable tubular member for limiting the travel of the said second valve comprising a split ring part located within the said tubular member, said second valve being associated with the hollow piston that is movable within 'thereceiving barrel member, a coiled spring, means for confining the coil spring between the upper end of the measuring barrel member and a fixed part on the tubular member, the construc tion and arrangement being such that when the tubular member is moved downward, the second valve will open to permit the creamlike material in the receiving receptacle to flow upward around the second valve and through the tubular member, and when pressure is removed from the tubular member, theexpansive force of the spring will return the parts to their normal position and cause the creamlike substance in the receptacle to lift the valve at the lower end of the receiving 7 barrel member and refill the same, as described.
