Application June 18, 1949, Serial No. 99,971l

6 Claims.

The object of this invention is to devise a novel device for applying lacquer, nail polish or other liquid material, and, while primarily designed for applying such material to nails, it is not limited to such use and can be employed for many other purposes.

A further object of the invention is to provide novel means for counterbalancing a brush so that, when the brush carrying end of the container is directed upwardly, the brush will be automatically retracted to be positioned in the delivery passage from the container for the material being dispensed.

A further object is to provide for limiting the outward travel of the brush, and for this purpose the rod which carries the brush is provided with a stop, which in some cases may be in the form of a valve to cooperate with a seat at the entrance end to the delivery passage. In this manner, the amount of material passing to the brush is metered. p

The counterbalance acts as a piston to effect the feed of the material to the brush and also as an agitator to maintain the liquid in a homogeneous condition.

With the foregoing and other objects in view as will hereinafter clearly appear, my invention comprehends a novel device for applying liquid material.

It further comprehends a novel construction and arrangement of a container and of a brush carrier having `a counterbalance or weight to retract the brush within the delivery passage of the container and also with means to limit the outward movement of the brush and if desired to control the amount of liquid fed -to the brush.

For the purpose of illustrating the invention, I have s-hown in the accompanying drawings preferred embodiments of it which I have i'ound in practice to give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and the invention is not limited to the exact arrangement and organization of these instrumentalities herein set forth.

Figure 1 is a perspective view of a device for applying liquid, embodying my invention.

Figure 2 is an exploded view of the component parts.

Figure 3 is a sectional elevation.

Figure 4 is a sectional view of a portion of the device in an inverted position.

Figure 5 is a sectional view of another embodiment of the invention.

Similar numerals of reference indicate corresponding parts.

Referring to -the drawings:

A tubular casing l has one end closed and the other 'end open and in Figures 1 to 4 inclusive the casing or container is sectional, being provided with a tip 2 connected with the body of the casing in any desired manner and as shown by a friction fit. IThe tip 2 at its inner end has a chamber 3 leading from thechamber of the casing and terminating in tapered walls forming a stop or seat 4 at the entrance end of a dispensing or delivery passage 5. The outer wall of the tip has a threaded portion 6 and preferably tapers forwardly towards its free end.

A brush l is secured in any desired or conventional manner to the outer end of a rod 8 which latter has secured to its inner end a weight or counterbalance 9 which is detachable since it is shown as in 'threaded engagement with the rod. Selectively positioned on the rod is a stop or seal l0 which may serve as a valve and controls thev amount of liquid passing to the brush. The counte'rbalance acts as a piston to feed the liquid to the delivery passage, and for different vlscositles of liquid a heavier or lighter counterbalance can be employed to control the flow in accordance with the character of the liquid which is being used. Thestop limits the outward movement of the brush so that only a desired amount of bristles are exposed.

A cap Il has a threaded portion l2 to engage the threaded portion 6 of the tip and when in closed position on the tip seals the outer end of the delivery passage 5.

The casing can be reillled with liquid on removal of the tip.

In the embodiment seen in Figure 5, the casing and tip are integral, and a closure i3 is detachably connected with the inner end of the casing. Otherwise the construction and arrangement of the component parts are the same as that already described in connection with Figures 1 to 4, inclusive.

The operation will now be readily apparent to those skilled in this art and is as follows:

The counterbalance has a clearance with the inner walls of the casing to limit the amount of pumping action, and since the casing has been shown as round the counterbalance has been shown as square. The rod has the requisite clearance in the delivery passage so that when the device is inverted the brush will be moved forwardly to be presented exterior of the front end of the top of the casing and a proper amount of liquid will tlow through the passage to the brush. The liquid dispensed can thus be applied to a desired surface without spilling or dripping.

When the brush end of the casing is directed upwardly, the counterbalance will automatically move inwardly carrying with it the brush and the stop or seal and the brush will be retracted into the delivery passage.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a device for applying liquid, a tubular casing closed at one end, having an internal chamber and having a tip with a discharge passage leading from the chamber, a rod Within the chamber, a brush at the outer end of the rod and within the passage when the casing is in an upright position with the tip directed upwardly, a weight within the casing and carried by the rod to move it and thereby the brush, said weight being free to move in either direction by gravity, whereby liquid is fed from the chamber to the passage and the brush is moved outwardly of the passage when the casing is inverted from an upright position, and the movement of the weight when the casing is returned to an upright position retracting the brush within the discharge passage.v

2, The construction deiined in claim 1, wherein the Weight is at the inner end of the rod, and a stop on the rod limits its outward movement.

3. In a device for applying liquid, a tubular casing closed at one end, having an internal chamber and having a tip with a discharge passage leading from the chamber to the discharge passage, a rod within the chamber and extending into the discharge passage with a clearance to permit liquid to pass around the rod, a brush at the outer end of the rod and within the passage when the casing is in an upright position with the tip directed upwardly, a weight carried by the rod to move it and thereby the brush, said weight being free to move in either direction by gravity, whereby liquid is fed from the chamber to the passage and the brush is moved outwardly of the passage when the casing is inverted from an upright position, and the movement of the weight when the casing is returned to an upright position retracting the brush with in the passage.

4. The construction deiined in claim 3, wherein the weight has a clearance with the inner wal-l of the chamber to permit liquid to bypass the weight.

5. yIn a device for applying liquid, a casing for liquid having a discharge passage, a brush normally within said passage to substantially close it when the casing is in an upright position with the discharge passage directed upwardly, a weight connected with the brush and free to move by gravity in opposite directions and of sufficient mass to retract the brush within the passage and to move itoutwardly of the passage, the tilting of the casing towards an inverted position causing the gravity movement of the weight tomove the brush outwardly oi the pasv sage and the return of the casing to an upright position retracting the brush within the passage.

6. In a device for applying liquid, a casing for liquid closed at one end, having an internal chamber and a discharge passage leading from said chamber, the inlet to said passage forming a seat, a rod within said chamber, a stop on the rod to engage the seat` and` seal said inlect, a brush connected with the outer end of said rod and normally within said passage when the casing is in an upright position with the passage directed upwardly, a weight connected with the rod and free to move by gravity in opposite directions to retract the brush within the passage or .move it outwardly thereof, the tilting of the casing towards an inverted position causing the gravity movement of the weight to move the brush outwardly of the passage and the return of the casingto an upright position causing a gravity movement of the weight to retract the brush within the casing.
