1 claims. (ci. :azi-60) The main object of this invention is the provision of a practical and simple device adapted to have a paste tube secured therein and to dispense4 the contents at a convenient point in predeter- 1 mined quantities which, in the case of-toothpaste, are of such a quantity as would commonly beused on a toothbrush.
In the example of theinvention which is illustrated in the drawings and described below, a dispenser for toothpaste is set forth, but it is to. be
distinctly understood that the invention may be carried out in the form4 of a ,dispenser for any other'substance lwhich is furnished on the market in so-called collapsible tubes, Vand it is therefore l5: not desired to limit the invention to the `form illustrated and described.
The above and other objects will become apparent in the description below; in 'which characters of reference refer to like-named parts in the 20. accompanying drawings.
Referring brieyto the drawings, Figure 1 is al side elevational view, of thedevice.
Figure 2 isl a plan viewoi the' same. j
Figure 3 is a front elevationalview of the same,
liliA partly in section.
Figure 4" is a rear elevational view of the same.
' Figure 5is a cross-sectional view taken on the line Bj-S fof Figure 3, showing .a tooth brush inserted.
y '30,. Figure 61is a cross-sectional view taken on the'-A vline of Figure3.'-. i
Figure-7 is' a cross-sectional view taken on the line`1'1 ofFigure 5.
,- Referring vindetail to the drawings, the numeral y,35, I0 indicatesthe base of a widened-U-shaped ,supe
port 'or ltramerh'afingthe .front-wall and the rear wall I2.` In'use-,l-.the `device may be mounted on the base l0, butfit may also be mounted in a position at right angles thereto with,.the base i3 secured to a 4wall by any suitable means, such as screws, not shown, with-the wall facing downward. f.
A- pairof parallel spaced-apart 'screw-threadedV rods or worms i3 are rotatablyl mounted in the opposite walls Il and |2 and their extremities project through both walls. On the outer side of the wall i2, pinions M are rigid on the .worms i3.
Between; the pinions' i4 a gear i5, inmesn with both pinions lli and having a knurled flange I6 rigid thereon and concentric therewith, is rotatably mounted in the wall i2.
On the outside off the wall il, ratchets il are rigid on the worms i3, and adjacent these ratchets gears I8. are loosely mounted on the worms. The
upper edge i9 of the wall is'turned outward at right angles. A slide 2li is mounted on the wall I l, and comprises essentially a plate 2| extending the width ofthe wall, having its top edge 22 and its bottom edge 23 both bent at right anglesl toward the wall, and having projecting tongues 24 |55 on its side edges bent at `right angles around the side edges of the wall The top and bottom edges 22 and 23 serve to keep the plate 2| at a distance from the wall I The plate 2| has a relatively wide vertical slot.10.
25 at its center and' near the side edges a pair' of relatively narrow vertical slots 25, these tlrreev slots extending throughout the height of the plate between its upper -and lower edges 22 and 23,'
respectively. 'A housing 21, -rectangular in hori. 15
zontal cross-section and open at the top, is secured about the center slot 25. The flooror the platform 28 of this housing has a cut-out 29 therein formed by cutting out a flap 30 on three sides, the
flap 3|) being then turned up at right angles to 20 provide a seal for the open end of the paste tube, as will presently become apparent.` Midway between the axes of therworms I3, an opening is provided in the wall in which alsleeve 3| is rotatably mounted with its ends projecting from 2,5,
both sides of the Wall An enlargedknurled flange 34 is rigid on and concentric with the lsleeve 3| on the inside of the wall Il, and a. spacer washer 32 lies between the disc portion 35 of the ilange 34 and the wall I I. '-A portion of the sleeve 0 3| which lies between the plate 2| and the wall i, is threaded and `receives a threaded-lock-and spacer-washer 33. TheV outer end of the sleeve 3| is slightly reduced and projects through the slot 25. The center portion 36 ofthe lower edge' 23 oi 1the plate 2| is cut out on its sides and-extends downward in the plane of the plate 2| in the form of a tongue or projection, in order to -slightly lengthen the slot 25. Integral with the sleeve 3| inside the flange 34 is an.internally`threaded 40 y collar 31, the threading of the same being complementary with that of a standard paste tube cap so that the threaded stern of the tube 38 may be screwed home thereinto.
On each of the worms and I2, frames or casings 39 are mounted which have openings 40 therein-facing each other. Mounted in the mutually opposed wallsl of these casings, one above and one below these worms |3, are the axles 4| of aA pair of rollers ,0. 43 and i6. Thelatter is shown corrugated and the former smooth-surfaced, although both may be of either finish. Rigid ori/the axles 4i and 42 of ,these rollers, are concave pinions 45 in' mesh with the worms I3.
is, between the walls 45.
, shown at 47'.
AdJacent each loose gear I8 is a vertical rack 45 integral with the plate 2i, whose teeth are adapted to engage the teeth oi the gears I8. 'I'he lower ends of the toothed sides of these racks slope away from the line of rack teeth. as Pawls 50, pivotally mounted on the gears I8. engage the ratchets Il'when the gears I3 turn in a clockwise direction (Figure 3) and ride loosely thereover upon rotation of the gears in the opposite direction. Co'iled springs 48, having their upper ends secured in the top edge I9 of the wall Ii and their lower ends in the door of the housing 2l, normally urge the entire slide' 20 into its uppermost position, and in this position the racks 4B are free of engagement with the gears i8 because of the abovementioned slopes il?.
In using the device, the knurled flange it is ilrst rotated to bring the rollers 43 and 44 close to the wall I2. Then, with the tube cap removed from the tube 3s, the stem of the latter is screwed home into the collar 31 by rotation of the flange 34. The tube is then held in such position as to keep its bottom edge 49 between the rollers 43 and 44 as the latter are moved in the opposite direction byy rotation of the ange I6 in the opposite direction. y As soon as a sufcient length of the tube edge 49 has been thus clamped between the rollers, thedevice is ready for use.
A toothbrush I shown in broken lines, is inserted through the open top of the housing 21 and pushed down against the fioor'28 of the latter. As soon as the slide 20 has thus been depressed a short distance against the pull of the springs lill,` the racks 48 will engage the loose gears IB, and continued depression of the slide will cause rotation of the gears I8 in a clockwise direction (Figure 3) and consequently rotation oi' the worms I3 in the same direction. and again consequently, advancement oi' the rollers 43 and Q4 toward the front wall il. As the rollers thus `vadvance, they will ride up on the tube 38 and squeeze a quantity of paste out through the sleeve 3i onto the brush 5I. As the surface of the brush has been riding past the paste outlet while the paste has been forced out, the paste will have been spread evenly along the lengthpf the brush. When thebrush is raised, the springs, 48 will restore the slide 20 to its uppermost position. and :lust before it reaches that position, the ap 30 Will begin to cover the sleeve outlet, in the uppermost position of the slide 20 the flap 30 will completely seal the sleeve outlet, as shown.
The rollers 43 and 44 might be loosely mounted in their end casings 39 without beinggeared to the worms I3 the casings 39 being instead threadably engaged with the worms, andthe device will function equally well, but in that case some means, not shown. must be tain the tube edge 69 in horizontal -position between tlie rollers to hold the tube taut in order to prevent buckling of that portion of the 'tube between the rollers and the wall 'I I.
Obviously, numerous modifications in form and structure may be made without departing from the spirit and scope of the invention.
