TOOTH-PASTE DISPENSER.

Application led May 2,

The object of my invention is to provide a suitable and convenient. me-ans of quickly dispensing a dentifrice paste or tooth paste onto a brush, requiringonly the use ofY one hand, andin a rapid and eiicient manner.

Reference will be had to the accompanying drawing in which Figure 1 is an elevationl of my machine, when same is hung up on the side of the wall, or a plan view where the machine is lying horizontal.

Figure 2 is a side view from that of Figure 1, showing'the tooth brush in a dierent position.

Figure 3 is a cross section of line 3 3 of Figure 2.

. Figure 4 is a transverse sect-ion on line 4--4 of Figure 1.

`Fig. 5 is a fragmentary section on line 5 5 of Figure 2.

@00th paste or dentifrice isalmost exclusively sold in what is known as collapsible tubes and it is the purpose of my invention to furnish an attachment in which these tubes may be placed and the tooth paste served therefrom by simply using the 'tooth brush as the instrument for the discharging of the paste onto the brush, thus making necessary the useof one hand only, which is a great convenience. In the drawing 1 indicates the tube and 2 the nozzle end with the screw cap removed and in place thereof there has been put a temporary plug or metal cork 3.

rIhis attachment or device is composed of a base or frame member 4 carrying some side members 5 which furnish the bearings 6 for a set of compression rolls 7, and the end 8 of the tube 1 is pushed in through these rollers 7 and thereby the paste is forced out from the nozzle 2 of the tube 1. Thebase member 4 is provided with the guide flanges 9 upon which there is av slidving block 10 (see Figure 4) to which by the rivets 11 there is fastened a guide plate 12.. This plate 12 andthe block 10 clasp in an elastic lit to the flanges 9 so that the block 10 will not move by gravity only, but will stay wherever put because ot a slight frictional contact on the lian es 9. The block 10 is provided with an a utment flange or projection 13 perforated and shaped'to lit over the nozzle end 2` of the tube and over the main portion of the tube as shown.

Block 10 has an extension 14, extending downward and between the flanges 9 and is 1924. Serial No. 710,486.

embossed with -a little cavity 15 adapted to receive the end 16 of the tooth brush shown on dotted lines in Figure 2.

A holder' for a.tooth brusl is made by cutting asunder and pressing out a lip or clasp piece 17 out of the side of the frame v which thus pushes the tube bodily toward the rolls 7 and thus brings about collapsible action in tube 1, which forces out the paste in an extruded portion indicated by 19.

In Figure. 2 the `action of gravity would deflect the extruding paste in a downward inclination as shown at 19 in Figure 2 when the device is laid horizontal, but would naturally extend out in a straight direction downward if the device is mounted in an upright position; In either case Whenever suiicient quantity has been discharged from the tube, the brush is withdrawn by swinging the handle dexterously and wiping, as it were, the paste oli' from the nozzle 2 laying the paste lengthwise onto the bristles of 'the brush in the manner most desired.

y The user pulls the plug, sticks in his brush with a. quick deXterous movement and withdraws it with the paste on it and then rapidly replaces the plug again, thus saving much time in the ordinary toilet service of handling these things.

The ordinary person who uses tooth paste with a tube has a habit of squeezing the tube` up inside the nozzle end, the region which I designate as 20 in Figure 2, leaving l the main bulk of the paste in the rear of the tube until zone 20 is exhausted. Frequently in the collapsing of zone 20 ruptures will be produced in the metal of the tube, thus preventing the balance of the contents of the tube .from being utilized. In my method of dispensing the tooth paste `the fullv contents ofthe tube is obtained with little or no loss, and with greater convenience to the user, and the time consumed brushing ones teeth is very much lessened. Inasmuch as mostfpeople do this every day, the item of time consumed in lthis toilet servllft ice is quite am iem besides the mammie? ou? 1@his eonveiiieiiee eec'tedwith the use my device,
