.Patented ,Feu 24, 1931 UNITED STATES PATENT :OFFICE CHARLES A.. yER'JOILA, OF SAN FRANCISCO, CALIFORNIA DISPENSING DEVICE Application 4le'd'lllecember 17, 1929. Serial No. 414,728,

My invention relates'to improvements in dispensing devices for tube contained products wherein rollers are' mounted in opposing relation upon .the front and back of a body and held in firm frictional contact with said body and a tube mounted upon said vbody for pressing the product outwardly from thetube.

The primary object of my invention is to provide an improved device for dispensing the contents from collapsible metal tubes.

Another object is to provide an improved dispensing device which will facilitate the expelling of plastic products from collapsible containers.

A further object is to provide an improved device wherein pressure is applied from the closed end of a collapsible tube to dispense a product therefrom, the product being fully and etiicientl expelled from the tube.

Another o ject is to provide an improved dispensing device which is light and compact and upon which a collapsible tube of a product to be dispensed may be readily attached and detached as desired.

A further object is to provide an improved device of the character described which can be economicall manufactured and which is durable and e cient. v I accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present application wherein llke characters of reference are used to designate similar parts throughout the specification and drawings, and in which- Fig. 1 is a front elevation of my improved dispensing device with a collapsible tube of a product to be dispensed mounted thereon; Fig. 2 is a side'elevation'of the device as 4shown in Fig. 1; s v

Fig. 3 is a side elevation of the device j after a portion of the contents of thetube have been dispensed;

V Fig.` 4 is a sectional view of the device 'taken uponthe line 4-4 of Fig. 3 in the direction indicated and showing the manner in'which the tube is collapsed; and

Fig. 5 is a broken detail view, drawn upon 5 an enlarged scale, as' showing the manner in -hold said closed end of the tube.

vially through the rollers. The springs 14 which the closed end of the tube is engaged.

Referring to the drawings, the numeral -1 1s used to designate in general a body, preferably formed from suitable sheet metal. The body 1 is provided with flanges 2 along 55 the longitudinal edges thereof, and rearwardly ofset mounting bracket portions 3 are formed at the ends to engage and hold the body in spaced relation to a wall or other suitable supporting surfaces. An opening 4 is preferably formed in the upper bracket portion 3 whereby the body may be suspended upon a screw or other suitable supporting member, not shown.

A pair of tube engaging lugs 6 are struck outwardly fromthe body adjacent the upper end thereof. The lugs are preferably ar. ranged to extend over the clamp member7 commonly applied u on the closed end of a collapsible tube `8 o the ordinary and well 70 l known form, said lugs preferably having sufficient resiliency to grip and eifectually A shouldered bead 9 is preferably formed along the free ends of the lugs 6 to seat the edges of the 75 clam member 7 of a tube and prevent said mem er 7 and the end of the tube from being forced downwardly out of engagement with the lugs. An annular band 11 is preferably mounted upon the body adjacent the lower end thereof to receive the tube and hold said tube in proximate parallel relation to the body.

A pair of rollers 12 and'13 are mounted in opposing relation upon the front and back of the body 1. The back roller 13 is received between the flanges 2 and engages the back surface of the body 1. The front roller 12 extends the full width of the body 1.- Spring members 14 are mounted at the' ends of the 90 rollers 12 and 13, said members 14 bein provided with bearing portions-16 rotatab y engaging the ends of shafts 17 extending axnormally exert a pressure holding the'rollers 95 in firm'frictional engagement with the front and back of the body 1. A knob 18 is secured upon an outwardly extending end of the shaft 17 of one of the rollers whereby said roller im may be rotated and both rollers moved longitudinally along the body 1. A pair of gears 19 may also be mounted if desired upon the shafts 17 in meshing relation to impart rotation from one of the rollers to the other.

Hooks 21 are preferably struck from the body 1 adjacent the lower end thereofto receive a tooth brush 22 or other object to be used with the product dispensed.

In operation, the rollers 12 and 13 Aare moved to the extreme top of the body 1, and a tube 8 of a product to be dispensed is mounted upon the body 1 by inserting the closed end of the tube under the lugs 6, the outlet end of the tube being inserted through the band 11. When the rollers are rotated in the directions indicated by the arrows in Figs. 2 and 3 of the drawings, said rollers, being held in frictional engagement with the front and back of the body 1 by means of the spring members 14, willA be rolled downwardly past the lugs 6 and the outer roller 1 2 will be moved' to engage the closed end of the tube 8.

When it is desired to dispense a portion of the contentsl of the tube 8, the usual cap 24; screwed onto the dispensing tip 25 of thc tube is removed, and the knob 18 turned in the direction indicated in Fig. 2, thereby rolling the outerroller downwardly onto 'the tube 8 and imposing a pressure sufficient to expel i a portion of the contents from the tube. As the roller 12 is moved downwardly, the roller 13 is moved a corresponding amount so that 4the rollers will bear upon opposite sides 0f the body and cause the tube to be pressed flat against the front of the body 1, as shown in Fig. 3, thereby completely expelling the contents of the tube downwardlytoward the dispensingoutlet. As the contents of the tube are displaced entirely by pressure from the closed end of the tube, the unemptied' portion ofthe tube will be kept expanded to its full symmetrical size, thereby presenting a neat appearance and preventing the unsightly distortion commonly encountered. After the desired amount of the product has been dispensed, the cap 24 is screwed onto the tip 25 to retain the remainlng product within the tube.

My improved device is particularly useful for dispensing .dentifrices, and in this connection, the hooks 21 afford a convenientv means for hanging tooth-brushes 22 upon the body 1.

While I have illustrated and described only one specific structure ofmy improved dispensing device, the details of construction are of course subect to modification in. nu-

merous ways. without departing from the spirit of my invention, and I therefore desire. to avail' myself Aof all modifications in structure and arrangement which may fall Within the scope of the appended claims.
